  In particular, referring to FIG. 7, the first opening 43 on the one end 17 side formed by the first through hole 41 and the second opening 44 on the other end 18 side formed by the second through hole 42. Are projected onto the vertical cross section in the short direction at the center in the longitudinal direction (that is, the vertical cross section of the VII-VII line shown in FIG. 2).

  If comprised in this way, after arrange | positioning two or more block structures, it inserts connecting tools, such as a wire rope, between one 1st through-hole and the other 2nd through-hole, In the space and the other second space portion, the block structures can be connected by fixing both ends of the connecting tool in a retaining state using a fixing tool such as a bolt.

  While it is possible to connect the block structure using the connecting tool and the fixing tool, the fixing tool can be stored in the space, so that the block structures can be connected and fixed by a simple mounting operation. It is possible to increase the safety by suppressing the protrusion of the tool.

  Further, a protrusion 25 is formed at one end 17 (that is, the left side) in the longitudinal direction of the main body 11, and a receiving portion 26 is formed at the other end 18 (that is, the right side). The reason for forming the protruding portion 25 and the receiving portion 26 in this way will be described later.

  Further, on the upper surface 15 of the main body portion 11, column insertion holes 27, 28, and 29 are formed for inserting and fixing columns of a protective fence such as a guard pipe, a guard rail, and a crossing prevention fence. The depth d of the column insertion holes 27, 28, 29 is set to 400 mm, which is smaller than the height H (= 450 mm) of the block structure 10.

  An inclined surface 37 and an inclined surface 38 are formed above the one end 17 and the other end 18 of the main body 11, respectively. The inclination angle with respect to the road surface set for the inclined surface 37 is different from the inclination angle with respect to the road surface set for the inclined surface 38.

  Below, the structure of the connection structure which connected block structures is demonstrated in detail.

  11 is an enlarged view of a P11 portion in FIG. 1, FIG. 12 is an arrow view in the direction of arrow XII shown in FIG. 11, and FIG. 13 is a view of the coupling tool and the fixing tool shown in FIGS. FIG. 14 is an enlarged view of a P12 portion in FIG. 11.

  First, with reference to FIG.11 and FIG.12, the connection structure 1 which connected block structure 10A (2nd block structure) and block structure 10B (1st block structure) is demonstrated. In the following description, when each part of the block structure 10A is shown for identification, “A” is added to the end of the code, and when each part of the block structure 10B is shown, “B” is added to the end of the code. .

  The connecting structure 1 is configured such that the other end 18A of the block structure 10A and the one end 17B of the block structure 10B are opposed to each other, and the protrusion 25B of the block structure 10B is opposed to the receiving portion 26A of the block structure 10A. The block structure 10A and the block structure 10B are arranged so as to be in a line in the longitudinal direction.

  The protruding portion 25B has a semi-cylindrical convex shape, and the receiving portion 26A has a concave shape corresponding to the convex shape. Therefore, in a state where the connection tool 50 is not connected, the block structure 10A has the receiving portion 26A in contact with the protrusion 25B, and the center S of the semi-cylindrical protrusion of the block structure 10B is used as an axis. The dimensions are such that they rotate about 15 ° in the direction of arrow M or arrow N, respectively.

  Further, a lubricant is applied to the first through hole 41B of the block structure 10B and the second through hole 42A of the block structure 10A, and the second through hole from the first space portion 31B side of the first through hole 41B. The communication tool 50 for connecting the block structure 10A and the block structure 10B is inserted through the second space portion 32A side of 42A.

  Next, referring to FIG. 13, the connector 50 includes a wire portion 51, a bolt portion 53 provided at one end of the wire portion 51, and a bolt portion 54 provided at the other end. .

  The fixtures 61 and 62 are composed of nuts 63 and 64 and washers 65 and 66, respectively.

  Next, referring to FIG. 14, on the side surface 35B of the first space portion 31B, the washer 65 of the fixing device 61 is attached to the bolt portion 53 of the connecting device 50 on the block structure 10B side, and the nut 63 is screwed. As a result, the connector 50 is fixed to the block structure 10A side in a retaining state.

  In addition, since it is the same also about the block structure 10A side, the description is not repeated here.

  With this configuration, for example, in the connection structure, even when an impact is applied from the M side to the N side in the short direction of the block structure, the connection tool is resistant to the impact, and the block structure 10A. Since the block structure 10B can rotate within a certain range as described above, a buffering effect due to this rotation can be expected, and the connected state can be maintained.

  The fixing tool 61 and the fixing tool 62 may be attached to such an extent that the connecting tool 50 is stretched between the block structure 10A and the block structure 10B, and may not be strained.

  In this way, when the block structures are coupled without tensioning the coupling tool, when the impact in the short direction as described above is applied, there is room for the block structures to move to each other, so that the buffering effect is achieved. I can expect.

  As described above, the connection structure 1 includes the block structure 10B, the block structure 10A arranged side by side on the one end portion 17B side of the main body 11B of the block structure 10B, and the first penetration of the block structure 10B. A connector 50 that is inserted from the first space portion 31B side of the hole 41B to the second space portion 32A side of the second through hole 42A of the block structure 10A, and connects the block structure 10B and the block structure 10A. In the first space portion 31B of the block structure 10B, the first fixing member 61 that is attached to make one end of the connector 50 to be retained from the block structure 10A side, and the first structure 61A of the block structure 10A. 2 In the space portion 32A, a second fixing tool 62 that is attached to make the other end of the connecting tool 50 to be retained with respect to the block structure 10B side; It is configured to include.

  If comprised in this way, a block structure can be connected flexibly according to road conditions, and the connection structure which improved the safety | security by suppressing protrusions, such as a fixing tool, can be obtained. Therefore, it is possible to form a separation band or the like by the connection structure more freely as desired.

  Further, when connecting, since the pair of insertion holes are connected to the first space portion and the second space portion, a wide working space can be secured. Therefore, workability when connecting the block structures is improved.

  Further, since the first space portion and the second space portion are respectively formed on the side surface portion of the main body portion, the space portion is covered with a part of the main body portion. Therefore, it is possible to prevent water and dust from accumulating in the space as compared with the case where the space is formed on the upper surface of the main body.

  FIG. 15 is a view showing a connection structure formed by connecting block structures according to the second embodiment of the present invention. Since the description is basically the same as that according to the first embodiment, the difference will be mainly described.

  Referring to FIG. 15, the connecting structure 1 according to the second embodiment is the first embodiment in that the block structure 10 </ b> A and the block structure 10 </ b> B are connected by the connecting tool 50 and the fixing tools 61 and 62. However, the structure of the space part etc. formed in each of the block structure 10A and the block structure 10B is different. Further, due to the difference in configuration, the connection method is different.

  16 is a front view showing an external shape of the block structure shown in FIG. 15, FIG. 17 is a plan view of the block structure shown in FIG. 16, and FIG. 18 is a block shown in FIG. 19 is a right side view of the structure, FIG. 19 is a left side view of the block structure shown in FIG. 16, and FIG. 20 is a cross-sectional view of the XX-XX line shown in FIG. FIG. 21 is a cross-sectional view of the XXI-XXI line shown in FIG. 16, and FIG. 22 is a cross-sectional view of the XXII-XXII line shown in FIG. Is a vertical sectional view in the longitudinal direction).

  With reference to these drawings, in the block structure according to the first embodiment, on the front side of the main body portion, the two space portions of the first space portion and the second space portion were provided. In the block structure 10 according to this embodiment, one space portion is provided on the front side of the main body portion.

  More specifically, the block structure 10 includes a main body portion 11 extending in the longitudinal direction and the front surface 13 side of the main body portion 11 at the center in the longitudinal direction and the center in the height direction from the surface of the main body portion 11. The space 70 formed toward the inside, the first through hole 41 communicating from the space 70 to the one end 17 of the main body 11, and the communication from the space 70 to the other end 18 of the main body 11. The second through hole 42 is provided.

  Further, the block structure 10 has a symmetrical space portion 74 formed on the back surface 14 side of the main body 11 at the center in the longitudinal direction and the center in the height direction from the surface of the main body 11 toward the inside. A symmetric first through hole 45 communicating from the symmetric space 74 to one end 17 of the main body 11 and a symmetric second through hole 46 communicating from the space 70 to the other end 18 of the main body 11 are provided. .

  A pair of insertion holes 21 and 22 for inserting a pair of claws of the forklift are formed on the bottom surface 20 of the main body 11 so as to extend from the front surface 13 to the rear surface 14 of the block structure 10 in the short direction. Yes. Furthermore, guide grooves 23 and 24 are provided in the upper part of the insertion holes 21 and 22 at the center in the longitudinal direction of the main body 11 so that a sling such as a wire rope or a belt sling can be guided, respectively.

  The space 70 has a substantially rectangular shape extending in the length direction. In addition, the other end of the first through hole 41 communicates with one side surface 71 (one end portion 17 side of the main body portion) of the space portion 70, while the other end of the second through hole 42 extends to the space portion 70. It leads to the other side surface 72 (the other end 18 side of the main body).

  A first opening 43 on the one end 17 side formed by the first through hole 41 and a second opening 44 on the other end 18 side formed by the second through hole 42 are short in the center in the longitudinal direction. The respective positions K1 projected on the vertical cross section in the hand direction (that is, the cross section of the XXI-XXI line shown in FIG. 16) are in the same positional relationship (see particularly FIG. 21).

  When configured in this way, when two or more block structures are arranged, a connecting tool such as a wire rope is inserted between one first through hole and the other second through hole, In the other space portion, the width of the connection method is widened by fixing both ends of the connection tool in a state where they are secured by using a fixing tool such as a bolt or by connecting the space portion through.

  The symmetric space 74 is formed symmetrically with respect to the space 70 and a vertical cross section in the longitudinal direction at the center in the short direction (that is, a cross section taken along line XXII-XXII shown in FIG. 17).

  Each of the symmetric first through hole 45 and the symmetric second through hole 46 is formed of a steel pipe embedded in the main body portion 11, similarly to the first through hole 41 and the second through hole 42. Each of the symmetric first through hole 45 and the symmetric second through hole 46 has a vertical cross section in the longitudinal direction at the center in the short direction (ie, as shown in FIG. 17). (Cross section of line XXII-XXII).

  A symmetric first opening 47 on the one end 17 side formed by the symmetric first through hole 45 and a symmetric second opening 48 on the other end 18 side formed by the symmetric second through hole 46 are provided. The respective positions K2 projected on the above-described vertical cross section in the short direction are in a positional relationship corresponding to each other (see particularly FIG. 21).

  Thus, the block structure 10 is a structure which can be connected with another block structure symmetrically on both the back side and the front side. If comprised in this way, when two or more block structures are arrange | positioned, connecting tools, such as a wire rope, are inserted between one symmetrical 1st through hole and the other 2nd symmetrical through hole also on the back side. And a block structure can be connected by fixing the both ends of a connection tool using fixing tools, such as a volt | bolt, in one symmetrical space part and the other symmetrical space part.

It is the structure provided with the 2nd fixing tool 62 attached in order to set it as a state.

  If comprised in this way, a row | line | column can be comprised flexibly by changing the number of several block structures, and it can connect efficiently. Therefore, it is possible to form a separation band or the like by the connection structure more freely as desired.

  From another point of view, the connection structure 1 includes a row in which the block structure 10A and the block structure 10B are connected in the longitudinal direction, and from the space 70B side of the first through hole 41B of the block structure 10B.

When each part of the structure 10H is shown, “H” is added to the end of the reference numeral.

  The connecting structure 1 has a second through hole 42F from the one end side of the first through hole 41F of the block structure 10F arranged at one end of the row among the block structures included in the row through the space portion 70F. Through the first through hole 41H of the block structure 10H arranged at the other end of the row among the block structures included in the row, through the space 70H to the other end side of the second through hole 42H, A connector 50 for connecting the block structures 10F, 10G, and 10H included in the row, and one end of the connector 50 at one end of the block structure 10F is retained with respect to the block structure 10H side. The other end of the connection tool 50 is secured to the block structure 10F side at the other end of the first fixing tool 61 and the block structure 10H to be attached.

For this reason, compared with the case where it connects between the adjacent block structures 10F and 10G and between the block structures 10G and 10H, the effort of a connection can be saved.

  Therefore, it is possible to flexibly configure the columns by changing the number of the plurality of block structures and to connect them efficiently.

  Furthermore, when attaching the first fixture 61 and the second fixture 62, a wide working space can be secured at one end of the first block structure and the other end of the second block structure. Therefore, compared with the case where a fixing tool is attached in the space part of the block structure of both ends, the workability | operativity which attaches a fixing tool also improves.
