てある。 At various construction sites such as road construction sites and subway construction sites, guard fences are erected on the boundary between the construction site area and the safe area (passable area) to prevent anyone other than those involved in the construction work from entering the construction site. At the same time, they are designed to prevent danger to passersby, cars, etc.

Ｂを隣接状態で立設する。 Conventionally, as shown in Fig. 1, a long H-shaped steel A is used as a base and laid on the boundary line between the construction site area and the safety area, and a tubular holding member D is installed between the lower end support legs C on both sides of the guard fence B using the H-shaped steel. The guard fence B was welded to A and the supporting legs C were inserted into this holding member D to hold the guard fence B upright. Similarly, H
A large number of guard fences B are erected adjacent to each other along the length direction of the shaped steel A.

とができない等の欠点を有していた。 However, in the above-mentioned guard fence erection technology, the H-shaped steel used as the foundation for erecting the guard fence is borrowed by the construction contractor from another company for a fee during the construction period, so it cannot be used on site. The holding member welded and fixed in
It must be removed when returning the shaped steel, and it takes time to fix and remove the holding member, and this requires
This also results in damage to the shaped steel. Further, there is a drawback that if the fixing position of the holding member is shifted, the support leg cannot be inserted.

断されることになる。 Next, if the lower end support legs 14, 14 on both sides of one guard fence 13 are inserted from above into the insertion part 6 on one side (inside) of the two frames 1 fixed to the H-shaped steel 11, each support leg 14, The lower end of 14 is placed on the upper end of support plate 12, and bolts 9, 9 are inserted into each screw hole 1.
0 and 10, and the tips of the bolts 9 and 9 are pressed against the support legs 14 and 14, respectively, so that the support legs 14 and 14 are fixed, and therefore the guard fence 13 is held in an upright state. Become. One support leg of another guard fence (not shown) adjacent to this guard fence 13 is inserted into the other insertion part 6 of the frame 1, and the other support leg is inserted into one side of another frame (not shown). The construction area and the safety area can be completely isolated by installing multiple guard fences 13 adjacent to each other along the length of the H-shaped steel 11 in the same way. It turns out.

上記する本考案によれば枠体１はＨ型鋼１１に
着脱自在であるとともに支持板１２の任意の位置

3 can be fixed, the frame 1 is attached in advance to both support legs 14 of the guard fence 13 installed at the end of the H-shaped steel 11, and both frames 1 are attached to the H-shaped steel support plate. 12 to hold the guard fence 13 upright, and then attach the support legs 14 on one side of another guard fence 13 adjacent to this guard fence 13 to the fixed frame 1 before attaching the support legs 14 on the other side. If the frame 1 is fixed to the support plate 12 and the support legs 14 on one side are attached to the pre-fixed frame 1 when the frame 1 is attached to the support plate 12, the frame 1 can be fixed to the support plate 12. There is no need to calculate the position for each support leg 14 interval.

もよい。 The thickness of the metal plate forming the frame body 1 is the same as the bolts 7 and 9.
If it is not sufficient to screw in and support the face plate 4.
A bolt insertion hole is simply drilled in the hole, and a nut is fixed to either the inner or outer surface of the face plate 4 facing this insertion hole.
The bolts 7 and 9 may be screwed into these nuts.
