  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A side groove block fence post attachment structure 100 according to the present invention will be specifically described below with reference to the drawings.

  As shown in FIG. 1, the side groove block 50 has a U-shaped side groove 53 formed between opposing side walls 51 and 52. An extension block 54 formed separately is attached to the road side wall 51 by being fixed to a locking hole (not shown) with a bolt (not shown).

  As shown in FIGS. 2 and 4, the mounting recess 10 is formed on the outer upper portion of the side wall 52 on the pedestrian side of the side groove block 50. The mounting recess 10 includes a central support wall 11 and fixed walls 12 and 12 that extend obliquely outward from both sides of the support wall 11. Bolt holes 13 and 13 are formed in the fixed walls 12 and 12, respectively. The fixed walls 12, 12 include top portions 14, 14, and a top portion 15 having a thinner width than the top portions 14, 14 is formed on the upper portion of the support wall 11. As shown in FIGS. 3 and 4, the top portion 15 has a plurality of recessed portions 16, 16, 16 formed on the outer periphery.

The fixture 20 is made of metal and has a substantially inverted W shape in plan view as shown in FIGS. 5 and 6. That is, the fixture 20 includes a plate-like first support portion 21, plate-like second support portions 24, 24 extending obliquely straight from both sides of the first support portion 21, and the second support. It consists of plate-like fixing parts 25 and 25 that extend obliquely straight from the tips of the parts 24 and 24, respectively. A protruding piece 22 is formed on the bottom of the first support portion 21, and a protrusion 23 is formed near the bottom. Locking holes 26 and 26 are formed in the fixing portions 25 and 25. The locking holes 26 and 26 are composed of small diameter portions 27 and 27 and large diameter portions 28 and 28 that communicate with each other.
The diameters of the small diameter portions 27 and 27 are wider than the shaft diameters of the bolts 30 and 30 so that there is play, and the small diameter portions 27 and 27 are formed to be inclined outward.

Next, a method of attaching the columnar fence post F to the fence post attachment structure 100 of the side groove block described above will be described.
The top 15 formed on the upper portion of the support wall 11 is crushed using a tool such as a hammer, and the top 15 is removed as shown in FIG. Since a plurality of recessed portions 16, 16, 16 are formed on the outer periphery of the top portion 15, the top portion 15 can be easily crushed and removed cleanly. In this way, the top part 15 is formed on the upper part of the support wall 11, and it is configured to be crushed and removed during construction, depending on the situation of the construction site, the interval for attaching the fence posts F may be wide or narrow, When it is not necessary to attach the fence posts F to all the mounting recesses 10 with a large attachment interval, if the upper part of the support wall 11 of the mounting recesses 10 to which the fence posts F are not attached is open outward, the mounting recesses 10 are within. This is because there is a possibility that trash will accumulate or a pedestrian may get caught in the opening, which is also not aesthetically pleasing. In addition, the number of pedestrians walking on the gutter block was small at the time of construction of the gutter block, and the fence was not attached considering the budget etc. When the number of slabs increases and it becomes necessary to attach a fence to prevent falling, it is not necessary to reconstruct the gutter block to change the gutter block to which the fence can be attached. Since the fence post F can be easily attached by crushing and removing with the use of, the useless construction can be avoided and the construction cost can be reduced.

  Next, the bolts 30 and 30 are temporarily tightened in the bolt holes 13 and 13. The large diameter portions 28, 28 of the attachment portion 20 are attached to the temporarily tightened bolts 30, 30, and then the attachment tool 20 is moved downward to attach the bolts 30, 30 to the small diameter portions 27, 27. The locking holes 26 and 26 are composed of small-diameter portions 27 and 27 and large-diameter portions 28 and 28 that communicate with each other, so that the bolts 30 and 30 can be easily attached to the large-diameter portions 28 and 28. Attachment to 20 bolts 30 and 30 becomes easy. Next, the fence post F is inserted between the support wall 11 and the fixture 20. As a result, the bottom of the fence post F comes into contact with the projection 23 formed near the bottom of the first support portion 21 and a downward force acts on the projection 23, so that the small diameter portions 27 and 27 are inclined outward. In combination with this, the fixture 20 is pressed in the direction of the fence post F, and the bolts 30 and 30 are difficult to be removed from the small diameter portions 27 and 27, and the bolts 30 and 30 are easily tightened. Further, when the gutter block is installed on an inclined ground, the diameter of the small diameter portions 27, 27 is designed to allow play with respect to the shaft diameter of the bolts 30, 30. The fence post F can be attached vertically or nearly vertically.

  Next, by tightening the bolts 30 and 30, as shown in FIGS. 7 to 10, the fence column F is fixed to the fixed walls 12 and 12 via the fixture 20 and pressed against the support wall 11. It is firmly fixed.

  When the fence post F is fixed via the fixture 20 formed in a substantially inverted W shape in plan view according to the present invention, the fixture 20 is point-contacted with the fence post F and A, B, C as shown in FIG. In addition, since the pressing force acts in the direction of the support wall 11 in any of A, B, and C, the fence column F can be firmly fixed. On the other hand, as shown in FIG. 12, when the fence post F is fixed with the plate P (corresponding to the attachment method of FIG. 9 of Patent Document 1), the plate P is in point contact with the fence post F with X, Y, Z. A pressing force acts in the direction of the support wall W only in X, and in Y and Z, the pressing force acts in a direction parallel to the support wall W, so the fence column F is fixed only by the pressing force in X. The fence post F cannot be firmly fixed. Although not shown, it can be fixed with an R-shaped plate that comes into surface contact with the fence post F. However, the plate that comes into surface contact with the fence post F becomes insufficient and avoids rattling. The fence post F cannot be firmly fixed. Actually, when the attachment state of the fence post F attached to the side groove block 50 was confirmed as described above, the fence post F was fixed extremely firmly in the attachment recess 10.
