It is related with the foundation for the equipment installation of the deck foundation roof which is the foundation of the, and its construction method.

Conventionally, facilities such as a solar panel unit for generating electricity using natural energy (sunlight) and a hot water unit for water heating, or an outdoor unit for an air conditioner have been installed on the roof of a building. To fix it, a foundation for installation is installed on the roof.
Further, a structure for installing a roof pedestal is disclosed to solve the problem that the load on the roof surface is increased by the concrete equipment installation foundation, and to secure the waterproof performance and stably install the equipment. (For example, refer to Patent Document 1).

JP 2011-208361 A (Page 5-6, FIG. 3A)

  The invention disclosed in Patent Document 1 is called a deck plate (hereinafter referred to as a “steel deck”) having a corrugated cross section (a crest-shaped crest and a crest-shaped trough are alternately continuous in the width direction). ) And a heat insulating material installed on the top surface of the mountain portion of the steel deck, a U-shaped receiving bracket having a head and a pair of legs, and a head of the receiving bracket The raising base which is the lip channel steel mounted in the board, and the fixed rail installed in the raising base.

  The pair of leg portions are pierced from the upper surface of the cross-section material, the lower ends (tips) of the pair of leg portions are pressed against the upper surface of the mountain portion of the steel deck, and the head is substantially the same as the upper surface of the heat insulating material It is at the same level. And the waterproof sheet which covers the head of a metal fitting and the upper surface of a heat insulating material is installed, and the metal fitting and the metal fitting in the state where the lip (the lower end of the flange) of the raising base is located on the head of the metal fitting via the waterproof sheet The raising platform is fixed to the mountain portion of the steel deck via a waterproof sheet by a tapping screw with a drill that penetrates the head of the receiving bracket and the web of the raising platform. Further, the raising base is covered with a waterproof covering material, and a fixed rail placed on the upper surface of the waterproof covering material is fixed to the fixed rail by a tapping screw with a drill through the waterproof covering material.

That is, in the invention disclosed in Patent Document 1, since a facility such as a solar panel unit is installed on the fixed rail, the load of the facility is locally applied to the peak portion of the steel deck. For this reason, there were the following problems.
(A) Since the load from the top of the equipment is concentrated on the steel deck, the legs of the catch on the steel deck's top (upper flange) are affected by the weight of the equipment, the load from the wind, earthquake, etc. There is a possibility that the pressed position and the web in the vicinity of the position (the slope portion between the upper surface of the peak portion and the lower surface of the valley portion) are locally deformed, buckled or collapsed.
(Ii) If the steel deck is crushed, the steel deck cannot support the load due to local deformation, which may lead to deformation or collapse of the roof itself. In particular, web buckling is a failure mode that must be avoided for steel.
(Iii) Further, with the local deformation or the like, the heat insulating material may sink or crack, or the waterproof sheet may sink or tear, and there is a concern about the collapse of the heat insulating mechanism or the waterproof function.

(E) Furthermore, if the support is installed at a position away from the support beam supporting the steel deck (position near the center of the support span), the steel deck will be bent due to bending deformation of the steel deck. Since the compressive force parallel to the direction of the support span acts on the mountain portion, the local deformation is promoted.
(O) Therefore, at this time, it is necessary to reduce the support span (narrow the distance between the support beams) or strengthen the steel deck (thickening, improving the quality). The degree of freedom during installation decreases (installation may be difficult).

The deck foundation roof equipment installation foundation and the deck foundation roof equipment installation foundation construction method according to the present invention have the following effects.
(I) The lower member is attached to the bottom of the valley of the steel deck directly above the beam, and equipment installation means for installing equipment on the upper member fixed to the lower member via a heat insulating material and a waterproof sheet is provided. Therefore, the load such as the weight of the equipment installed by the equipment installation means is transmitted to the beam via the bottom surface (lower flange) of the steel deck. That is, the load of the equipment is difficult to be transmitted to the top surface portion (upper flange) of the steel deck.
(A) For this reason, local deformation, buckling or crushing of the top surface portion (upper flange) or side surface portion (web) of the steel deck is prevented. Therefore, the possibility that the roof itself is locally deformed or collapses is eliminated.
(B) Furthermore, since the heat insulating material is prevented from sinking or cracking due to local deformation or the like, or the waterproof sheet is settling or tearing, the heat insulating mechanism and the waterproof function are prevented from collapsing.

(C) Furthermore, since the lower member is attached directly above the beam, bending deformation of the steel deck is prevented. For this reason, there is no need to reduce the support span (narrow the distance between the support beams) or strengthen the steel deck (thickening, improving the quality), especially the degree of freedom when attaching to the existing deck base roof Will not drop (it may be difficult to install).
(D) In addition, even in the case of a roof that needs to have a fireproof structure, the loading conditions when obtaining the roof fireproof certification of the steel deck do not become severe.

(Ii) Moreover, since the front end edge of the lower leg part of the lower member has penetrated into the concave groove of the steel deck, attachment is easy, and the load of the equipment is reliably transmitted to the steel deck.
(Iii) Moreover, since the inter-member heat insulating material is installed between the upper bottom surface and the lower top surface, it is difficult for heat from the facility or the outside to be transmitted to the beam via the steel deck. Moreover, since the upper member is fixed to the lower top surface by the center fixing means via the inter-member heat insulating material, the fixing becomes easy and reliable.
(Iv) Since the lower top surface is held by the head of the member fixing bolt constituting the center fixing means and the intermediate nut, and the upper top surface portion is held by the intermediate nut and the upper nut, the fixing mechanism is simple. Fixing is easy and reliable.
(V) Moreover, since the member fixing bolt and the lower member are not in direct contact, heat transfer between them is suppressed.

(Vi) Further, since the upper member is fixed to the pair of mountain top surfaces via the heat insulating material between the members by the peripheral fixing means, the fixing becomes easy and reliable, and the rotation of the upper member with respect to the steel deck is prevented. The
(Vii) Since the surrounding fixing means is a tapping screw, the fixing mechanism is simple, and fixing is easy and reliable.

(Viii) Furthermore, since a part of the lower leg portion of the lower member is fixed to a part of the steel deck by fillet welding or screwing, the foundation for installing the equipment for the deck base roof is securely attached to the steel deck. Therefore, the reliability as the foundation for equipment installation is improved.
(Ix) Furthermore, since a clearance edge is formed on the lower leg portion of the lower member, the clearance edge is parallel to the ridge of the steel deck, and the bottom of the lower leg portion is pressed against the bottom portion. By simply rotating the member, the lower leg can be easily and reliably attached to the steel deck.

In FIG. 8A to FIG. 8C, the construction method of the deck base roof equipment installation base (hereinafter sometimes referred to as “construction method”) for attaching the equipment base 200 to the deck base roof 100 is a pre-assembled facility. The foundation 200 for installation is attached to the steel deck 10, and the deck base roof 100 is completed after that.

(Assembling the foundation for equipment installation)
The assembling of the facility installation base 200 is to fix the upper member 40 to the lower member 20 via the inter-member heat insulating material 33.
That is, with the lower heat insulating material convex portion 31 c of the lower heat insulating material 31 inserted into the lower through hole 24 of the lower member 20, the lower heat insulating material surface 31 b of the lower heat insulating material 31 and the intermediate heat insulating material surface 32 b of the intermediate heat insulating material 32 To sandwich the lower top surface 22. Then, the lower washer 82 is brought into contact with the lower surface of the lower heat insulating material 31, the intermediate washer 83 is brought into contact with the upper surface of the intermediate heat insulating material 32, and the lower washer 82, the lower heat insulating material hole 31a, the intermediate heat insulating material hole 32a, and the intermediate washer 83 are formed. An intermediate nut 84 is screwed onto the penetrating member fixing bolt 81 to fix the member fixing bolt 81 to the lower member 20 (see FIG. 8B).

  Further, the member fixing bolt 81 is passed through the central through hole 33 a of the inter-member heat insulating material 33, and the upper nut 85 of the upper member 40 is screwed to the member fixing bolt 81. That is, the assembly is completed by rotating the upper member 40 until the upper bottom surface portion 44 contacts (slides) the inter-member heat insulating material 33 with respect to the lower member 20 fixing the member fixing bolt 81. To do. At this time, the intermediate washer 83 enters the counterbore portion 33b of the inter-member heat insulating material 33, the upper surface of the intermediate nut 84 comes into contact with the lower surface of the upper bottom surface portion 44, and the central through hole 33a of the inter-member heat insulating material 33 (FIG. 7A). (See below).

(Deck foundation roof completed)
After the deck base roof 100 is installed on the bottom surface 14b of the steel deck 10 directly above the beam 90 to prevent the upper member 40 from rotating, the roof heat insulating material 91 and the roof waterproof sheet 92 are attached. Then, the waterproof reinforcement sheet 93 is installed across the part of the upper member 40 exposed above the roof waterproof sheet 92 and part of the roof waterproof sheet 92 (FIG. 1). reference).

(Installation of equipment installation foundation)
FIGS. 9A and 9B illustrate a construction method of a foundation for installing a deck foundation roof according to Embodiment 2 of the present invention. FIG. 9A shows an initial stage of attaching a lower member to the deck foundation roof. FIG. 9B is a partial plan view seen through a part explaining the end of the attachment, and FIG. 9B is a partial plan view seen through a part explained.
9A and 9B, the procedure for attaching the lower member 20 of the equipment installation base 200 to the deck base roof 100 is as follows. First, the lower relief edges 29a and 29b of the lower member 20 are the protrusions 17b and 17c of the steel deck 10. The lower leg portions 27 a and 27 b of the lower member 20 are pressed against the valley bottom surface 14 b of the steel deck 10 in a state parallel to the front end of the steel deck 10. That is, since the distance L (see FIG. 9B) between the lower clearance edge 29a and the lower clearance edge 29b is smaller than the distance H between the protrusion 17b and the protrusion 17c (L <H), the lower clearance edge 29a , 29b does not interfere with the tips of the ridges 17b, 17c.

Therefore, the lower member 20 is rotated with the normal of the valley bottom surface 14b as the center of rotation while the lower leg portions 27a, 27b are pressed against the valley bottom surface 14b of the steel deck 10. At this time, the lower surface of the inter-member heat insulating material 33 abuts (slides) on part of the top surfaces 13a and 13b.
Then, the lower tip edges 28a and 28b of the lower member 20 enter the concave grooves 18b and 18c, respectively, and the lower legs 27a and the lower legs 27b (the lower tip edge 28a and the lower tip edge are formed by the grooves 18b and 18c. (Same as 28b) and are pressed downward by the ridges 17b and 17c (more precisely, the lower surfaces of the ridges 17b and 17c forming the concave grooves 18b and 18c) ( (See FIG. 9B).
That is, at the initial rotation of the lower member 20, the intersection (corner) between the lower tip edge 28a and the lower relief edge 29a and the intersection (corner) between the lower tip edge 28b and the lower relief edge 29b are concave. The lower side faces 23a and 23b are elastically deformed by strongly abutting (sliding) on the groove 18b and the concave groove 18c, and when the rotation of the lower member 20 further proceeds, the lower tip edges 28a and 28b and the concave groove 18b, 18c becomes parallel.

At this time, the distance M (see FIG. 9A) between the lower tip edge 28a and the lower tip edge 28b is the depth of the groove 18b (the portion where the lower surface of the ridge 17b forming the groove 18b intersects the valley bottom surface 14b). And the depth G of the groove 18c (corresponding to a portion where the lower surface of the protrusion 17c forming the groove 18c and the valley bottom surface 14b intersect) is longer than M (G> G). Although the amount of elastic deformation of the lower side surfaces 23a and 23b is reduced, it is still in an elastically deformed state. Therefore, as described above, the lower end edges 28a and 28b of the lower member 20 are gripped by the grooves 18b and 18c. The
Therefore, the lower member 20 is in a state where it can reliably contact the steel deck 10 and pass force to each other by a simple operation.

  Next, a tapping screw 87 that penetrates the peripheral through hole 46 of the upper member 40 and the inter-member heat insulating material 33 is screwed (installed) on the top surfaces 13a and 13b. That is, the upper member 40 cannot be rotated with respect to the steel deck 10 (rotation with respect to the lower member 20) by the tapping screw 87 (see FIGS. 1 and 2B).

(Installation of roof insulation)
The roof heat insulating material 91 is formed with a roof heat insulating material through hole 91a through which the upper main body portion 41 of the upper member 40 passes. Accordingly, the roof heat insulating material 91 is installed on the mountain top surfaces 13a and 13b in a state where the upper bottom surface portion 44 of the equipment installation base 200 attached to the steel deck 10 so as not to rotate by the tapping screw 87 is covered (see FIG. 1). ).
In addition, as the roof heat insulating material 91, it is comprised from the roof partial heat insulating material 91b which only covers the upper bottom face part 44, and the roof whole heat insulating material 91c in which the range equivalent to the roof partial heat insulating material 91b is a space (through-hole). However, the roof partial heat insulating material 91b and the entire roof heat insulating material 91c may be integrated.
In addition, when the equipment installation foundation 200 is attached to the existing deck base roof, a through hole that covers the upper bottom surface portion 44 is formed in the existing roof heat insulating material, and the equipment installation equipment is installed via the through hole. The foundation 200 may be attached to the steel deck 10, and then a roof heat insulating material (corresponding to the roof partial heat insulating material 91b) that closes the through hole may be installed.

(Installation of roof tarpaulins)
The roof waterproof sheet 92 is formed with a sheet through hole 92a through which the upper main body portion 41 of the upper member 40 passes. Therefore, the roof waterproof sheet 92 is installed in a state of covering the roof heat insulating material 91 (the roof partial heat insulating material 91b and the entire roof heat insulating material 91c).
Further, the waterproof reinforcing sheet 93 is installed across a part of the upper member 40 above the roof waterproof sheet 92 and a part of the roof waterproof sheet 92.
The waterproof reinforcing sheet 93 includes a sheet cylindrical portion 93a that surrounds the upper main body portion 41, and a planar seat flange portion 93b that is formed continuously toward one end of the sheet cylindrical portion 93a toward the outer packet. doing. And the sheet | seat cylindrical part 93a, the upper side surface 43, the sheet | seat flange part 93b, and the roof waterproof sheet 92 are adhere | attached by the solvent-type or heat-melt-type adhesion | attachment means (refer FIG. 1).
In addition, although the adhesion means 93c and 93d are waterproof seal agents and caulking agents, the present invention is not limited to this, and a waterproof tape may be applied across both members.

  The construction method for attaching the facility installation base 200 to the deck base roof 100 is not limited to the construction method described in FIGS. 8A to 8C. First, the lower member 20 is formed into the valley bottom surfaces 14a to 14c of the steel deck 10. And then other components for installation may be attached, or after assembling a part of the installation base 200 as shown in FIG. 8B, this is applied to the valley bottom surfaces 14a to 14c of the steel deck 10. The deck foundation roof 100 may be completed by attaching and then attaching other parts of the equipment installation foundation.

(Function and effect)
The equipment installation base 200 has the above-described configuration, and the deck base roof 100 is formed by being attached to the steel deck 10 in the manner described above.
(A) The load such as the weight of the equipment installed on the upper member 40 is transmitted to the beam 90 via the valley bottom surface 14c of the steel deck 10, and is difficult to be transmitted to the peak surfaces 13a and 13b. Therefore, local deformation, buckling or crushing of the top surfaces 13a, 13b or the inclined surfaces 15a, 15b, 15c, 15d is prevented. Therefore, the possibility that the deck base roof 100 is deformed or collapses is eliminated.
(B) Further, since the sinking and cracking of the roof heat insulating material 91 or the sinking and tearing of the roof waterproof sheet 92 due to local deformation or the like is prevented, the heat insulating mechanism and the waterproof function are prevented from collapsing.
(C) Furthermore, since the lower member 20 is attached immediately above the beam 90, bending deformation of the steel deck 10 is prevented. For this reason, there is no need to reduce the support span (narrow the spacing between the support beams) or strengthen the steel deck 10 (thickening, improving quality), especially when installing on an existing deck basement roof. The degree of freedom is not reduced (installation may be difficult).

(D) Since the lower end edges 28a and 28b of the lower member 20 and the lower legs 27a and 27b of the lower member 20 have intruded into the concave grooves 18a and 19b of the steel deck 10, installation is easy and The load is reliably transmitted to the steel deck 10.
(E) Since the inter-member heat insulating material 33 is installed between the upper bottom surface portion 44 and the lower top surface 22, the equipment or external heat transmitted to the upper member 40 is transmitted to the steel deck 10. It has become difficult.
(F) Since the member fixing bolt 81 passes through the lower heat insulating material hole 31a of the lower heat insulating material 31 and the intermediate heat insulating material hole 32a of the intermediate heat insulating material 32 and does not directly contact the lower member 20, the upper member 40 The equipment or external heat transmitted to the lower member 20 is hardly transmitted to the lower member 20.

(G) Since the upper member 40 is fixed to the lower top surface 22 by the member fixing bolt 81 and the upper nut 85 (corresponding to the center fixing means) via the inter-member heat insulating material 33, the fixing is easy and Be certain.
(H) Since the upper member 40 is fixed to the top surfaces 13a and 13b via the inter-member heat insulating material 33 by the peripheral through hole 46 and the tapping screw 87 (corresponding to the peripheral fixing means), the fixing is easy. In addition, the upper member 40 cannot rotate with respect to the steel deck 10 (lower member 20).

(L) Furthermore, since a part of the lower leg portions 27a and 27b of the lower member 20 is fixed to a part of the steel deck 10 by fillet welding or screwing, for installation on the deck base roof 100 Since the foundation 200 is securely attached to the steel deck 10, the reliability as the equipment installation foundation 200 is improved.
(Nu) Furthermore, since the lower relief edges 29a, 29b are formed on the lower legs 27a, 27b of the lower member 20, the lower relief edges 29a, 29b are made parallel to the protrusions 17a, 17b of the steel deck 10, The equipment installation foundation 200 can be easily and reliably attached to the steel deck 10 simply by rotating the lower member 20 with the tips of the lower legs 27a and 27b pressed against the valley bottom surface 14c.

[Embodiment 3]
FIG. 10 is a front sectional view for explaining a foundation for installing a deck foundation roof according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted.
In FIG. 10, a deck installation roof equipment installation foundation (hereinafter referred to as “equipment installation foundation”) 300 includes member fixing bolts 88 in place of the upper nut 85 in the equipment installation foundation 200 described in the first embodiment. The upper member 340 is used which is fixed by welding with the threaded portion facing downward.
That is, the lower nuts 89a and 89b are screwed onto the member fixing bolt 88 welded and fixed to the upper member 340 in the pocket of the lower main body portion 21 (below the lower washer 82). That is, since the lower nuts 89a and 89b function as double nuts, the member fixing bolt 88 and the lower nuts 89a and 89b have a structure that is difficult to loosen. Further, the intermediate nut 84 is unnecessary.
In the above, the head of the member fixing bolt 88 is fixed to the upper surface of the upper bottom surface portion 44 by welding, but the head of the member fixing bolt 88 may be fixed to the lower surface of the upper bottom surface portion 44 by welding. At this time, it is not necessary to process the intermediate through hole 45 in the upper bottom surface portion 44.

[Embodiment 4]
FIG. 11: is sectional drawing of the front view which isolate | separates each member which demonstrates the construction method of the foundation for the equipment installation of the deck foundation roof which concerns on Embodiment 4 of this invention, and shows mutual up-and-down relation. In addition, the same code | symbol is attached | subjected to the part which is the same as Embodiment 3, or an equivalent part, and a part of description is abbreviate | omitted.
In FIG. 11, the upper member 40 is fixed to the lower member 20 via an inter-member heat insulating material 33.
First, only the lower member 20 is installed on the component deck 10 (see Embodiment 2).
Therefore, the intermediate heat insulating material 32 is placed on the upper surface of the lower top surface 22. Then, the inter-member heat insulating material 33 is brought into contact with the upper surface of the intermediate heat insulating material 32 and the mountain top surfaces 13a and 13b of the steel deck 10 (accurately, a slight gap may occur without making contact). At this time, the intermediate heat insulating material hole 32 a of the intermediate heat insulating material 32 and the central through hole 33 a of the inter-member heat insulating material 33 coincide with the position of the lower through hole 24 of the lower member 20.

Next, member fixing bolts 88 fixed by welding to the upper member 340 are inserted into the intermediate heat insulating material hole 32 a, the central through hole 33 a and the lower through hole 24, and the upper bottom surface portion 44 is inserted into the upper surface of the inter-member heat insulating material 33. Is placed.
Then, the lower heat insulating material 31 and the lower washer 82 are inserted into the member fixing bolt 88, and the lower nuts 89a and 89b are screwed into the member fixing bolt 88. At this time, the lower heat insulating material convex portion 31c of the lower heat insulating material 31 is inserted into the lower through hole 24 of the lower member 20, and the lower heat insulating material surface 31b of the lower heat insulating material 31 and the intermediate heat insulating material surface 32b of the intermediate heat insulating material 32 are used. The lower nuts 89a and 89b are made to function as double nuts with the lower top surface 22 interposed therebetween.
Then, a tapping screw 87 that penetrates the peripheral through hole 46 of the upper member 340 and the inter-member heat insulating material 33 is screwed (installed) on the top surfaces 13a and 13b. That is, the upper member 40 cannot be rotated with respect to the steel deck 10 (rotation with respect to the lower member 20) by the tapping screw 87 (see FIG. 9). Alternatively, after the tapping screw 87 is screwed to the top surfaces 13a and 13b, the lower nuts 89a and 89b may be tightened to function as a double nut.
Thereafter, similarly to the second embodiment, the roof heat insulating material 91, the roof waterproof sheet 92, the waterproof reinforcing sheet 93, and the adhesion means 93c and 93d are installed.

Therefore, the same effect as the construction direction in Embodiment 2 can be obtained, and the upper member 40 can be more reliably installed over a long period of time.
In the above, the lower heat insulating material 31 is inserted into the member fixing bolt 88 after the upper member 40 is placed. However, the present invention is not limited to this, and the inter-member heat insulating material 33 is intermediately heat-insulated. Before placing the upper surface of the material 32, the lower top surface 22 may be sandwiched between the lower heat insulating material surface 31 b of the lower heat insulating material 31 and the intermediate heat insulating material surface 32 b of the intermediate heat insulating material 32.
Further, the lower heat insulating material 31 including the lower heat insulating material convex portion 31 c may be installed on the upper surface of the lower top surface 22. At this time, an intermediate heat insulating material 32 may be installed on the lower surface of the lower top surface 22, or a second lower heat insulating material 31 may be installed.

  Since the present invention has the above-described configuration, the load of the equipment installed on the deck base roof does not act locally on the mountain portion of the steel deck, so that equipment of various weights exhibiting various functions can be installed. It can be widely used as a foundation for installing equipment on the deck base roof.
