Abstract

The present invention provides a structure installation stand that has high strength against both load and wind pressure, has a small number of parts, and can reduce costs.
When the entire structure installation stand 1 is seen, a mounting bar 4, a vertical column 5 and a tension bar 6 are combined in a right triangle shape. In the gantry 1 configured in such a right triangle shape, this force is distributed to the mounting beam 4, the vertical column 5, and the tension bar 6 regardless of the direction of the force acting on the mounting beam 4. Therefore, the strength of the gantry 1 is increased. In addition, the inclined end surface portion 12d and the tip portion 4a, which are the two overlapping of the tip beam portion 12 of the mounting beam 4, have a strength higher than that of one portion, and the reinforcing member 13 It is reinforced. For this reason, even if the force applied to the mounting bar 4 is concentrated on the tip 4a, the tip 4a can withstand this force.

Description

  The present invention relates to a structure installation stand suitable for installing a flat structure such as a solar cell module on the ground or a flat roof.

  In this type of conventional frame, legs are often provided in consideration of installation on the ground or a flat roof. For example, when supporting a solar cell module, four legs are erected on the ground or a flat roof, a rectangular frame is fixedly supported on these legs, and the solar cell is mounted on the frame. The module is mounted. Also, the two front leg portions are shorter than the two rear leg portions, the frame body is inclined, and the light receiving surface of the solar cell module is substantially directed in the incident direction of sunlight (Patent Document). 1 and 2).

  On the other hand, since the flat solar cell module is easily subjected to wind pressure, it is necessary to sufficiently increase the strength of the mount not only for the load of the solar cell module but also for the wind pressure.

  For example, as shown in FIG. 17A, in the structure in which the leg portions 102 and 103 are erected vertically and the frame body 101 is supported by the leg portions 102 and 103, the frame body 101 and the frame body 101 are provided. Since the load G of the solar cell module 104 acts in parallel with the legs 102 and 103, the strength of the legs 102 and 103 with respect to the load G can be increased.

  However, when wind pressure F acts on the solar cell module 104 as shown in FIG. 17B, the wind pressure F acts on the legs 102 and 103 obliquely, and thus is perpendicular to the legs 102 and 103. Since not only the direction force f1 but also the force f2 in the direction orthogonal to the leg portions 102 and 103 acts, the force f2 in the orthogonal direction acts in the direction of tilting the leg portions 102 and 103. The strength of the legs 102 and 103 tends to be insufficient.

  Alternatively, as shown in FIG. 17C, when the leg portions 102 and 103 are provided perpendicular to the frame body 101, the wind pressure F acts in parallel with the leg portions 102 and 103. The strength of each leg part 102 and 103 becomes high.

  However, as shown in FIG. 17 (d), since the load G of the frame body 101 and the solar cell module 104 on the frame body 101 acts obliquely on the leg portions 102, 103, the leg portions 102, 103 are provided. The force g1 in the vertical direction and the force g2 in the direction orthogonal to the legs 102 and 103 act on the force G2, and the force g2 in the orthogonal direction acts in the direction in which the legs 102 and 103 are tilted. The strength of the legs 102 and 103 tends to be insufficient.

  That is, as shown in FIGS. 17A and 17B, when the legs 102 and 103 are erected vertically, even if the strength against the load G is high, the strength against the wind pressure F tends to be insufficient. When the legs 102 and 103 are provided perpendicular to the frame body 101 as shown in FIGS. 17C and 17D, the strength against the load G tends to be insufficient even if the strength against the wind pressure F is high. .

For this reason, conventionally, the front two leg portions 102 are set up vertically and the rear two leg portions 103 are provided perpendicular to the frame body 101 so that both the load G and the wind pressure F can be obtained. The strength of the connection between the legs 102 and 103 and the frame body 101 is made sufficiently high after the legs 102 and 103 are erected vertically so that the strength is not insufficient, and the load G and wind pressure F are increased. It was stronger than any of the above.

  However, when the front leg portions 102 are erected vertically and the rear leg portions 103 are provided perpendicular to the frame body 101 as in the prior art, the front side with respect to the load G Even if the strength of each leg portion 102 is high, the strength of each leg portion 103 on the rear side is insufficient, and even if the strength of each leg portion 103 on the rear side is high with respect to the wind pressure F, Since the strength of the leg portion 102 was insufficient, the strength did not increase sufficiently with respect to both the load G and the wind pressure F.

  In addition, in order to sufficiently increase the connection strength between the leg portions 102 and 103 and the frame body 101 after the leg portions 102 and 103 are erected vertically, the strength of the component parts and the connection portions is sufficiently high. And the number of parts needs to be increased, resulting in increased costs and complicated on-site assembly work.

  Therefore, the present invention has been made in view of the above-described conventional problems, and has high strength with respect to both load and wind pressure. An object of the present invention is to provide a structure installation stand that can be maintained, has a small number of parts, and can reduce costs.

  In order to solve the above-mentioned problems, the structure installation stand of the present invention has two foundation portions spaced apart from each other, and the tip of a mounting bar on which the structure is placed is placed on one of the foundation portions. Fixing, fixing the vertical support post between the other of the foundations and the mounting post, and arranging the mounting post and the vertical support vertically, thereby tilting the mounting post The tip of the mounting bar fixed to the one base part is formed by bending a metal plate so that two sheets are stacked, and the two ends are stacked. The part is fixed to the one base part.

  The mounting bar is formed by bending a metal plate so as to have at least two side plates extending in the longitudinal direction of the mounting bar, and the front side of each side plate is bent. Two side-by-side stacks are formed, and the inclined end surface portion of the mounting bar is formed by the front end side of each side plate that is the two-layer stack, and the side plates that are stacked in two so as to be parallel to the base portion A tip portion on the tip side is bent to form a tip portion ahead of the inclined end surface portion, and the tip portion is fixed to the base portion.

  Further, the structure installation stand of the present invention is a structure installation stand in which the mounting beam on which the structure is placed is supported by being inclined, and the mounting beam described above extends in the longitudinal direction of the mounting beam. A metal plate is bent so as to have at least two side plates parallel to each other, and the front end side of each side plate is folded into two layers, and the two side plates are stacked by the front end side of each side plate. In addition to forming the inclined end surface portion of the mounting beam, the front end portion of each side plate stacked in parallel with the base portion is bent so that the front end portion ahead of the inclined end surface portion is formed. The tip is fixed to the base.

  And, the other foundation part is arranged apart from the foundation part, the vertical support is interposed and fixed between the other foundation part and the installation post, and the installation post and the vertical support are fixed. Are arranged vertically, thereby supporting the mounting rail in an inclined manner.

  Further, the vertical strut is formed by bending a metal plate so as to have at least two side plates extending in parallel with each other in the longitudinal direction of the vertical strut. The lower end surface portion of the vertical column is formed by the lower end side of each of the two side plates stacked, and the lower end surface portion is fixed in contact with the other base portion.

  Moreover, the tension bar which connects each said base part is provided.

  Furthermore, the mounting beam includes a main beam portion extending in a longitudinal direction of the mounting beam, and a tip beam portion connected and fixed to one end of the main beam portion, and the tip beam portion is inclined. It has an end face part and the tip part ahead of the inclined end face part.

  In addition, a reinforcing member is provided that is overlapped and fixed to the distal end portion on the distal end side of each of the two stacked side plates, and that abuts both the upper surface of the distal end portion and the inclined end surface portion.

  In such a structure installation stand of the present invention, the tip of the mounting beam is fixed to one foundation part, and the vertical support is interposed between the other foundation part and the mounting beam, And vertical struts are arranged vertically, and the mounting bars are inclined and supported. Thereby, the mount frame which combined the mounting bar and the vertical support | pillar in the shape of a right triangle on two foundation parts is comprised.

  In the gantry constructed in such a right triangle shape, this force can be received in a distributed manner regardless of the force acting on the mounting bar from any direction. For this reason, even if a load or wind pressure is applied while a flat structure such as a solar cell module is placed and fixed on a mounting bar, the cradle can withstand these loads and wind pressure. be able to.

  In addition, since the main components are only the two basic parts, the mounting bar, and the vertical support, the number of parts is small, the cost can be kept low, and the assembling work is easy.

  In addition, since the mounting bar and the vertical column are arranged vertically, when the wind pressure acts on the flat structure on the mounting beam vertically, this wind pressure is applied in parallel to the vertical column. And the strength against the wind pressure is sufficiently high.

  In such a right triangle shape, even if the force can be received in a distributed manner, all the force concentrates on the connection portion with the base portion, so it is necessary to increase the strength of the connection portion with the base portion. Therefore, the metal plate is bent so that two sheets are stacked to form the tip portion (vertical apex of the right triangle) of the mounting rail, and the two stacked end portions are used as one base portion. It is fixed to increase the strength between the tip of the mounting bar and one of the foundations.

  For example, the mounting bar is formed by bending a metal plate so as to have at least two side plates parallel to each other extending in the longitudinal direction of the mounting bar, and the front side of each side plate is bent to overlap two sheets. The inclined end surface portion of the mounting bar is formed by the tip side of each of the two side plates stacked, and the tip of the side plate of each side plate stacked so as to be parallel to the base portion The tip portion is bent to form a tip portion ahead of the inclined end surface portion, and the tip portion is fixed to the base portion. That is, one metal plate is bent to form a two-layered tip portion, and this tip portion is fixed to the base portion.

  Further, in the structure installation stand of the present invention, the mounting bar is formed by bending a metal plate so as to have at least two side plates extending in the longitudinal direction of the mounting bar. The front end side of each of the side plates is folded to form two stacked sheets, and the inclined end surface portion of the mounting bar is formed by the front end sides of the two side plates stacked, and the two stacked sheets are parallel to the base portion. The front end portion of each side plate is bent to form a front end portion ahead of the inclined end surface portion, and this front end portion is fixed to the base portion.

  Since the force acting on the gantry concentrates on the connection location between the gantry and the foundation, it is necessary to increase the strength of the location where the gantry is connected. Therefore, the metal plate is bent so that two sheets are overlapped to form the tip end portion of the mounting bar, and the tip end portion formed by stacking the two sheets is fixed to the base portion.

  Then, the other foundation part is arranged away from the foundation part, the vertical support is interposed and fixed between the other foundation part and the mounting support, and the mounting support and the vertical support are arranged vertically. The support bar is inclined and supported.

  Thereby, the mount frame which combined the mounting bar and the vertical support | pillar in the shape of a right triangle on two foundation parts is comprised. And, as described above, the gantry constructed in the shape of a right triangle is a state in which a flat structure such as a solar cell module is mounted and fixed on a mounting bar, as described above. Even if wind pressure acts, the mount can withstand these loads and wind pressures.

  In addition, since the mounting bar and the vertical column are arranged vertically, when the wind pressure acts on the flat structure on the mounting beam vertically, this wind pressure is applied in parallel to the vertical column. Therefore, it has sufficient strength against this wind pressure.

  Further, with respect to the vertical struts, the metal plate is bent so as to have at least two side plates extending in parallel with each other in the longitudinal direction of the vertical struts, and the front end side of each side plate is bent to form two sheets. A front end surface of the vertical column is formed by the front end side of each of the stacked side plates, and this front end surface is fixed in contact with another base portion. Thereby, the intensity | strength of the connection location of a vertical support | pillar and another foundation part can also be raised.

  Moreover, since the tension bar which connects each foundation part is provided, between each foundation part is reinforced. When installing each foundation at a location with high strength such as the ground, there is no need to provide a tension bar. However, when installing each foundation at a location with low strength, a tension bar is provided for each foundation. It is necessary to reinforce between the parts.

  Further, the mounting beam is divided into a main beam portion and a tip beam portion, and the mounting beam is assembled by combining the main beam portion and the tip beam portion. As a result, the tip beam portion is shortened and the manufacture thereof becomes easy, and as a result, the mounting beam is easily manufactured. If a long mounting bar is manufactured integrally, it is necessary to bend one long metal plate, but it is necessary to fold the tip side into a predetermined shape. A space that allows movement of the metal plate, such as up, down, left, and right, is required, which makes bending difficult.

  In addition, a reinforcing member is provided which is overlapped and fixed to the front end portion on the front end side of each of the two side plates stacked, and abuts on both the upper surface and the inclined end surface portion of the front end portion. Since the inclined surface of the mounting bar and the upper surface of the tip part form an angle with each other, a reinforcing member is brought into contact with these surfaces to prevent the tip part from bending in the direction in which the mounting bar rises. be able to.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing an embodiment of the structure installation stand of the present invention. The structure installation stand 1 of this embodiment is for installing flat structures, such as a solar cell module, on the ground or a flat roof. In this gantry 1, a pair of foundation parts 2 and 3 are installed on the ground or a flat roof at a certain distance, the tip part 4 a of the mounting bar 4 is connected and fixed to one foundation part 2, and the vertical column 5 is attached. It is interposed and fixed between the other base 3 and the mounting bar 4, the mounting bar 4 and the vertical column 5 are vertically arranged with each other, and a tension bar 6 is bridged between the bases 2 and 3. It is fixed.

  As shown in FIG. 2, each base portion 2, 3 is formed by projecting a bolt 8 on a rectangular base 7, and the rectangular base 7 is fixedly arranged on the ground or a flat roof with the bolt 8 facing upward. To do.

  The mounting bar 4 is a combination of the main bar 11 and the front bar 12 having a hat-shaped cross section as shown in FIGS. 3A and 3B. As shown in d), the front crosspiece 12 is connected and fixed to one end of the main crosspiece 11.

  The vertical support 5 has a U-shaped cross section as shown in FIG. Further, the tension bar 6 has an L-shaped cross section as shown in FIGS. 1 and 4A to 4D.

  Each of the mounting bar 4, the vertical column 5 and the tension bar 6 is obtained by cutting and bending a metal plate such as a plated steel plate.

  Here, as shown in FIGS. 1 and 4A to 4D, the bolt 8 of the base portion 2 is inserted through the hole of the tip portion 6a of the tension bar 6, and the tip portion 6a of the tension bar 6 is used as the base portion. 2, the bolt 8 is inserted into the hole of the tip portion 4 a of the mounting bar 4, the bolt 8 is inserted into the hole of the reinforcing member 13, and the tip portion 6 a of the tension bar 6 is mounted on the base portion 2. The front end 4a of the mounting bar 4 and the reinforcing member 12 are sequentially overlapped, and after that, a washer is inserted into the bolt 8, and a nut 15 is screwed into the bolt 8 and tightened. As a result, the tip 6 a of the tension bar 6 and the tip 4 a of the mounting bar 4 are fixed on the foundation 2.

  Further, as shown in FIG. 5, the bolt 8 of the base portion 3 is inserted into the hole of the rear end portion 6 c of the tension bar 6, the rear end portion 6 c of the tension bar 6 is placed on the base portion 3, and the lower end of the vertical column 5 The bolt 8 of the base portion 3 is inserted into the hole of the surface portion 5 a, and the bolt 8 is inserted into the hole of the holding member 16. And the presser member 16 are sequentially stacked, and then a washer is inserted into the bolt 8 and a nut 18 is screwed into the bolt 8 and tightened. Thereby, the rear end portion 6 b of the tension bar 6 and the front end portion 4 a of the mounting bar 4 are fixed on the base portion 3.

  Further, as shown in FIG. 1, the upper end portion of the vertical column 5 is inserted into the inside of the hat-shaped main beam 11, the bolt 19 is passed through the main beam 11 and the vertical column 5, and a nut (not shown) is inserted into the bolt 19. And the vertical column 5 is connected and fixed to the main beam 11. The upper ends of the vertical struts 5 are positioned and connected so that the vertical struts 5 and the main beam 11 are arranged perpendicular to each other.

  As described in detail later, such a structure installation stand 1 is used by arranging a plurality of structures on the ground or a flat roof. A plurality of structure installation stands 1 are arranged in parallel and fixed substantially, and a plurality of horizontal beams are horizontally laid on the mounting beam 4 of each structure installation frame 1, and a solar cell module is installed between these horizontal beams. To support.

  As is apparent from FIG. 1, when the entire structure installation stand 1 is viewed, the mounting bar 4, the vertical column 5, and the tension bar 6 are combined in a right triangle shape. In the gantry 1 configured in such a right triangle shape, the force acting on the mounting beam 4 can be distributed and received on the mounting beam 4, the vertical column 5, and the tension bar 6. The strength of 1 is increased. For example, the load of the solar cell module mounted on the mounting beam 4 and the wind pressure applied to the solar cell module can be distributed and received on the mounting beam 4, the vertical column 5, and the tension bar 6. .

  Further, the cross-sectional shape of the mounting bar 4 is made a hat shape to increase its cross-sectional strength, and the cross-sectional shape of the vertical support 5 is made U-shaped, or the cross-sectional shape of the tension bar 6 is made L-shaped. , Their cross-sectional strength is increased. That is, the strengths of the components of the mounting bar 4, the vertical column 5, and the tension bar 6 are also increased.

  Note that the tension bar 6 may be omitted as long as the foundations 2 and 3 can be firmly attached to the flat roof and the positional deviation between the foundations 2 and 3 does not occur. However, when the base portions 2 and 3 are installed on the ground, the tension bar 6 is necessary.

  By the way, in a right triangle structure composed of the mounting bar 4, the vertical column 5, and the tension bar 6, the force can be distributed and received on the mounting bar 4, the vertical column 5, and the tension bar 6. Since this force finally concentrates on the front end portion 4a of the mounting bar 4 and the lower end surface portion 5a of the vertical column 5, it is necessary to increase the strength of these portions.

  Therefore, in the present embodiment, a structure for exceptionally increasing the strength is adopted for both the front end portion 4 a of the mounting bar 4 and the lower end surface portion 5 a of the vertical column 5.

  Next, the structure of the front end 4a of the mounting bar 4 will be described. The mounting beam 4 is a combination of a main beam portion 11 and a tip beam portion 12 as shown in FIGS. The main beam portion 11 is formed by bending a metal plate so that the cross-sectional shape thereof becomes a hat shape, and an intermediate plate 11a extending in the longitudinal direction of the main beam portion 11 and each of the parallel portions on both sides of the intermediate plate 11a. It has the side plate 11b and each edge plate 11c which protrudes from the edge of each side plate 11b to both sides. The front crosspiece 12 is formed by bending a metal plate in the same manner as the main crosspiece 11, and includes a middle plate 12a, side plates 12b, and edges 12c, and further forward from the middle plate 12a. It has a protruding inclined end surface portion 12d and a tip end portion 4a ahead of the inclined end surface portion 12d.

  As shown in FIG. 1, engaging holes 11 d are formed at a plurality of positions spaced apart from each other on the middle plate 11 a of the main crosspiece 11. Further, as shown in FIG. 3A, in the vicinity of one end of the main beam portion 11, two holes 11e are formed in the intermediate plate 11a, and two holes 11e are formed in each edge 11c, for a total of six. The hole 11e is formed.

  As shown in FIG. 3 (b), an opening hole 12f is formed in the middle plate 12a of the tip crosspiece 12. In addition, two holes 12g are formed in the middle plate 12a of the tip bar portion 12, and two holes 12g are formed in each edge 12c, respectively, so that six holes 12g are formed in total.

  As shown in FIGS. 4A to 4D, the front beam portion 12 is fitted inside one end of the main beam portion 11, and the six holes 11 e of the main beam portion 11 and the six holes of the front beam portion 12. 12 g are overlapped, and six bolts 21 are inserted into the holes 11 e and 12 g, nuts 22 are screwed into the bolts 21 and tightened, and the main beam portion 11 and the tip beam portion 12 are combined and fixed. At this time, the opening hole 12f of the front beam portion 12 overlaps with the engagement hole 11d near one end of the main beam portion 11, and the engagement hole 11d near one end of the main beam portion 11 is opened.

  FIG. 6 is an expanded view of the front end crosspiece 12. The front crosspiece 12 is obtained by cutting a metal plate such as a plated steel plate into the developed shape of FIG. 6 and bending the developed shape of the metal plate, folding each folding line 23 into a mountain, and folding each folding line 24. Are folded to form the middle plate 12a, each side plate 12b, and each edge 12c, the folding line 25 of each side plate 12b is folded in a mountain, and the front end side of each side plate 12b is overlapped to form the inclined end surface portion 12d. And the tip end portion 4a ahead of the inclined end surface portion 12d, and further, the folding line 26 between the inclined end surface portion 12d and the tip end portion 4a is valley-folded, so that the tip end portion 4a becomes the tip beam portion 12 (mounting beam). It is inclined with respect to the longitudinal direction of 4). And as shown in FIG.3 (b), the hole 4b is formed in the front-end | tip part 14a.

  Here, since the front end 4a of the mounting bar 4 is fixed to the base part 2 and the vertical column 5 is fixed between the base part 3 and the mounting bar 4, the mounting bar 4 is inclined. Supported. In this state, the tip portion 4 a that is valley-folded by the fold line 26 is just parallel to the upper surface of the rectangular base 7 of the base portion 2.

  For this reason, as shown in FIGS. 4A to 4D, the distal end portion 4a is placed on the rectangular base 7 of the base portion 2 via the distal end portion 6a of the tension bar 6, and the reinforcing member 13 is further provided thereon. When the nuts 15 are screwed into the bolts 8 and then tightened, the tip 4a is pressed evenly against the upper surface of the rectangular base 7 of the foundation 2 via the tip 6a of the tension bar 6, and the tip 4a Is firmly fixed on the base 2.

  Further, the reinforcing member 13 has a U-shaped cross-sectional shape as shown in FIG. 7, and is formed with a hole 13a at the center thereof and edge plates 13c on both sides thereof. The front end side of each edge plate 13c is cut obliquely to form each contact end face 13d.

  When the reinforcing member 13 is placed on the distal end portion 4 a of the distal end beam portion 12, the contact end surfaces 13 d of the reinforcing member 13 are directed toward the inclined end surface portion 12 d of the distal end beam portion 12 as shown in FIG. 8. Then, a nut 15 is screwed into the bolt 8 and tightened, the lower surface of the reinforcing member 13 is brought into pressure contact with the distal end portion 4a of the distal end beam portion 12, and each contact end surface 13d of the reinforcing member 13 is inclined to the inclined end surface portion 12d of the distal end beam portion 12. Pressure contact. As a result, the inclined end surface portion 12d of the front end crosspiece portion 12 is pressed, the front end portion 4a of the front end crosspiece portion 12 is reinforced, and the front end portion 4a is prevented from being bent in the direction in which the mounting crosspiece 4 is raised. it can.

  As described above, the front end 4a of the mounting bar 4 is formed by bending a development-shaped metal plate shown in FIG. 6, and has an inclined end surface portion 12d and a front end portion 4a that are stacked in two pieces, This distal end portion 4 a is fixed to the base portion 2. Further, the reinforcing member 13 reinforces the distal end portion 4a of the distal end crosspiece portion 12 so as not to bend in the direction in which the mounting crosspiece 4 rises.

  In FIG. 6, reinforcing plates 12e indicated by alternate long and short dash lines are attached to the two sides of the inclined end surface portion 12d, and these reinforcing plates 12e are folded inside the end beam portion 12 and overlapped with each side plate 12b. Thus, the strength of the front crosspiece 12 may be further increased.

  Next, the structure of the lower end surface portion 5a of the vertical column 5 will be described. As shown in FIG. 9, the vertical support 5 is formed by bending a metal plate so that the cross-sectional shape thereof is a U-shape, and is similarly long as the intermediate plate 5 c extending in the longitudinal direction of the vertical support 5. The side plates 5d are parallel to each other and extend in the direction. And the folding line 5e of each side plate 5d is mountain-folded, the front end side of each side plate 5d is overlapped to form a lower end surface portion 5a, and a hole 5b is formed in the lower end surface portion 5a.

  As shown in FIG. 5, the lower end surface portion 5a of the vertical column 5 is placed on the rectangular base 7 of the base portion 3 via the rear end portion 6c of the tension bar 6, and the presser member 16 is further stacked thereon. The nut 18 is screwed into the nut 8 and tightened to fix the lower end surface portion 5 a formed by overlapping the vertical struts 5 to the base portion 3.

  In this way, the inclined end surface portion 12d and the distal end portion 4a are provided on the distal end beam portion 12 of the mounting beam 4 so as to overlap each other, and the distal end portion 4a is fixed to the base portion 2, and the vertical support 5 is A lower end surface portion 5 a that is stacked is provided, and the lower end surface portion 5 a is fixed to the base portion 3.

  The inclined end surface portion 12d and the front end portion 4a, which are the two stacked front end beam portions 12 of the mounting beam 4, have a strength higher than that of one portion and are reinforced by the reinforcing member 13. For this reason, even if the force acting on the mounting bar 4 is concentrated on the tip portion 4a, the tip portion 4a can withstand this force.

  Similarly, since the strength of the lower end surface portion 5a of the two vertical struts 5 stacked is also high, even if the force acting on the mounting bar 4 is concentrated on the lower end surface portion 5a of the vertical strut 5 The lower end surface portion 5a can withstand the force.

  For example, in a state where the solar cell module is mounted on the mounting bar 4, the load of the solar cell module acts on the mounting bar 4, the vertical column 5, and the tension bar 6 in a right triangle shape. A horizontal force and a vertical force are concentrated and applied to both the front end portion 4 a of the mounting bar 4 and the lower end surface portion 5 a of the vertical column 5.

  Further, when wind pressure acts on the solar cell module on the mounting rail 4, this wind pressure also acts to increase the horizontal force and the vertical force applied to the front end portion 4 a and the lower end surface portion 5 a.

  However, since the strength of the tip portion 4a and the lower end surface portion 5a is high, the tip portion 4a and the lower end surface portion 5a can withstand these forces, and the solar cell module can be supported without hindrance.

  If the strength of the tip portion 4a and the lower end surface portion 5a is not high, the tip portion 4a and the lower end surface portion 5a cannot withstand the load and wind pressure of the solar cell module, and these are deformed or damaged.

  In other words, because the strength of the front end 4a and the lower end surface 5a is increased, it is possible to adopt a right-angled triangular structure composed of the mounting bar 4, the vertical column 5, and the tension bar 6. I can say that.

  In addition, since the vertical support 5 is arranged perpendicular to the mounting beam 4, the wind pressure acting on the mounting beam 4 can be received by the vertical support 5, and against a large wind pressure in severe weather conditions. Even withstand.

  Furthermore, although the tip 4a of the mounting bar 4 and the lower end surface 5a of the vertical column 5 are high in strength, they are obtained by cutting and bending one metal plate, which increases the number of parts. There is no invitation.

  Next, the construction example of the structure installation stand 1 of this embodiment is demonstrated. FIG. 10 shows a plurality of structure installation stands 1 arranged side by side to support a flat structure such as a solar cell module. Here, four structure installation stands 1 are arranged side by side at regular intervals, and three horizontal rails 27 are arranged horizontally at predetermined intervals on the mounting bars 4 of each structure installation stand 1. It is handed over. Further, two vertical crosses 28 are bridged between two vertical columns 5 adjacent to each other to reinforce each vertical column 5.

  A plurality of solar cell modules (not shown) are arranged side by side between the lower and central two horizontal rails 27. Similarly, a plurality of solar cell modules are arranged between the two horizontal rails 27 at the center and upper side. Solar cell modules (not shown) are fixed side by side.

  In this structure installation stand 1, as shown in FIGS. 1 and 10, engagement holes 11 d are formed at a plurality of locations of the main beam portion 11 of the mounting beam 4. As shown in FIG. 11, the main beam portion is formed. 11, the tap metal fitting 31 is attached from the back side of the middle plate 11a through the engagement hole 11d, the pair of support pieces 31a of the tap metal fitting 31 are projected to the front side of the intermediate plate 11a, and the horizontal rail 27 is interposed between the pair of support pieces 31a. It is sandwiched and supported.

  As shown in FIG. 12, the tap metal fitting 31 has a screw hole 31c formed in the middle plate 31b, side plates 31d provided on both sides thereof, bent in double, and further protruding from the center of each side plate 31d. A support piece 31a is provided.

  The upper end of the side plate 31d is made lower than the upper surface of the middle plate 31b, and the gap Pa between the upper end of the side plate 31d and the T-shaped support piece 31a is defined as the gap between the upper surface of the middle plate 31b and the T-shaped support piece 31a. It is wider than Pb.

  Further, the lateral width Qa of the tap fitting 31 is set to be slightly narrower than the inner separation distance Qb (shown in FIG. 11) of the side plates 12b of the main crosspiece 11.

  As shown in FIGS. 13A and 13B, the one support piece 31a of the tap metal fitting 31 is inserted into the insertion slit 11f of the main rail 11, and the one support piece 31a is inserted into the engagement hole from the insertion slit 11f. Next, the other support piece 31a of the tap metal fitting 31 is inserted into the insertion slit 11f, and the other support piece 31a is also moved from the insertion slit 11f to the engagement hole 11d. The T-shaped head is hooked on the engagement hole 11 d and the tap metal fitting 31 is attached to the main crosspiece 11. At this time, each side plate 31 d of the tap metal fitting 31 is disposed perpendicularly to each side plate 11 b of the main crosspiece 11.

  When inserting the support piece 31a of the tap metal 31 into the insertion slit 11f, it is necessary to incline the tap metal 31 with respect to the middle plate 11a of the main crosspiece 11. However, in the state where the tap metal 31 is inclined, the tap metal Since both edges of the engagement hole 11d are passed through the wide gap Pa between the upper end of the side plate 31d of the 31 and the T-shaped support piece 31a, the insertion work of the support piece 31a of the tap metal fitting 31 is facilitated.

  Further, by simply hooking the T-shaped head of each support piece 31a to the engagement hole 11d, the tap metal fittings until the T-shaped head of one support piece 31a abuts the edge of the engagement hole 11d. 31 is slid along the engaging hole 11d in the downward direction of the main crosspiece 11, and the tap metal fitting 31 is in a suspended state, but the insertion slit 11f is provided in the upwardly inclined direction with respect to the engaging hole 11d. Therefore, the T-shaped head of each support piece 31a does not fall out of the insertion slit 11f.

  Note that the engagement hole 11d and the insertion slit 11f in the vicinity of the front end of the middle plate 11a of the main crosspiece 11 overlap the opening hole 12f of the middle plate 12a of the front crosspiece 12 so that the engagement hole 11d and the insertion slit 11f are overlapped. Each support piece 31a of the tap metal fitting 31 is inserted through the opening hole 12f.

  In this way, after attaching the tap metal fitting 31 to the engaging hole 11d of the main crosspiece 11 of the mounting crosspiece 4, the horizontal crosspiece 27 is arranged between the pair of support pieces 31a of the tap metal 31 as shown in FIG. At the portion of the metal fitting 31, the holding member 32 is overlapped with the horizontal beam 27, and the bolt 33 is screwed into the screw hole 31 c of the tap metal fitting 31 through the hole of the holding member 32 and the groove hole 27 a of the horizontal beam 27 to tighten the horizontal beam 27. It fixes to the main crosspiece part 11 of the mounting crosspiece 4.

  At this time, since the lateral width Qa of the tap fitting 31 is set to be slightly narrower than the inner separation distance Qb of each side plate 12b of the main crosspiece 11, there is almost no gap between the tap fitting 31 and the main crosspiece 11. Further, the middle plate 31 b of the tap metal fitting 31 overlaps and comes into close contact with the middle plate 11 a of the main crosspiece 11. Accordingly, there is almost no gap between the tap metal 31 and the main beam part 11 at the upper and side portions of the tap metal 31, and the main beam part 11 is reinforced at the part of the tap metal 31.

  Moreover, since each side plate 31d of the tap metal fitting 31 is arranged perpendicular to each side plate 11b of the main crosspiece 11, the side plate 11d of the tap metal fitting 31 prevents the side plate 11b of the mounting bar 11 from being bent. Each side plate 11b of the mounting bar 11 is strongly reinforced, and deformation such as twisting of the mounting bar 11 is prevented.

  For this reason, even if a large load or force is applied to the tap metal 31, the main beam 11 is not deformed or damaged at the portion of the tap metal 31, and the tap metal 31 is dropped from the main beam 11. There is nothing.

  Next, the construction procedure for supporting the solar cell module using a plurality of structure installation stands 1 as shown in FIG. 10 will be described.

  First, three horizontal rails 27 are laid over each mounting rail 4, and for each horizontal rail 27, the horizontal rail 27 is disposed between a pair of support pieces 31 a of each mounting rail 4, and each bolt 33 Are screwed into the screw holes 31c of the tap fittings 31 of the mounting bars 4 and tightened to fix the horizontal bars 27 to the mounting bars 4. At this time, the lower horizontal rail 27 is securely fixed by tightening each bolt 33 strongly. Moreover, about the center and upper side crosspiece 27, each bolt 33 is lightly clamped and temporarily fixed.

  Subsequently, the fixing bracket 43 is fixed to the horizontal rail 27 for each horizontal rail 27 using a bolt 41 and a screw fitting 42 as shown in FIG. The fixing metal 43 has a hooking claw 43a at its upper end, and engages the hooking claw 43a with one side of the solar cell module to fix and support the solar cell module. One set is used.

  Further, as shown in FIGS. 15A and 15B, an eaves edge cover 44 is attached in front of the lower horizontal rail 27.

  Thereafter, as shown in FIG. 16A, the solar cell module 45 is inserted between the lower horizontal rail 27 and the central horizontal rail 27. In practice, a plurality of solar cell modules 45 are arranged side by side between the lower horizontal beam 27 and the central horizontal beam 27.

  At this time, the bolts 33 temporarily fixing the central crosspiece 27 are loosened, and the tap fittings 31 supporting the central crosspiece 27 are moved along the engaging holes 11d of the mounting bars 4. To adjust the position of the central horizontal rail 27 and bring the central horizontal rail 27 into contact with the upper side of the solar cell module 45.

  Subsequently, the upper side of the solar cell module 45 is lifted as shown in FIG. 16B, and the lower side of the solar cell module 45 is pressed against the lower side rail 27 as shown in FIG. 16C. As a result, the hooking claws 43 a of the fixing fitting 43 engage with the engaging grooves 45 a on the lower side of the solar cell module 45.

  Further, as shown in FIG. 16 (d), the upper side of the solar cell module 45 is lowered and placed on the central cross rail 27.

  Then, the central horizontal beam 27 is pressed against the upper side of the solar cell module 45, and the solar cell module 45 is sandwiched between the lower horizontal beam 27 and the central horizontal beam 27. In this state, the central horizontal beam 27 is The bolts 33 that are temporarily fixed are firmly tightened to securely fix the central crosspiece 27. As a result, the solar cell module 45 is sandwiched between the lower horizontal rail 27 and the central horizontal rail 27 and firmly supported.

  The solar cell module 45 is sandwiched and supported between the central horizontal rail 27 and the upper horizontal rail 27 in the same procedure.

  In addition, this invention is not limited to the said embodiment, It can deform | transform variously. For example, although the cross-sectional shape of the mounting bar is a hat shape, it may be a U shape or a C shape. Moreover, although the mounting beam is divided into the main beam portion and the tip portion, it is not necessarily required to be divided. Since the tip portion alone is short and easy to bend, it is divided into a main beam portion and a tip portion. For example, if the main beam and the tip are integrated, the direction and position of the tip changes when the tip is bent, and the direction and position of the long main beam change accordingly. Space is required, and the machining work becomes difficult.
