However, in the above-mentioned prior art, when the columns of the temporary enclosure are to be erected without driving the columns into the ground, as shown in FIG.
Is necessary, and since a large number of columns 40 are set up,
The number of support members 42 required increases. Creating and securing these multiple supports 42 to the columns 40 requires a lot of material and labor time. Furthermore, after the temporary enclosure was removed,
Since the support member 42 is unnecessary and is discarded, the material is wasted. Moreover, since the support member 42 protrudes from the temporary enclosure, there is a risk that the construction worker may get his feet caught on the support member 42 during walking and break off. In addition, even if the temporary enclosure is provided with the support member 42, there is a concern that the temporary enclosure may fall down due to strong wind. Therefore, it is necessary to periodically check the state of the support member 42. If the state of the support member 42 is poor, the maintenance must be performed. Must. These regular checks and maintenance are cumbersome, time consuming, and if possible,
This is the operation you want to delete. In addition, if there are retaining walls, block walls, etc., it may not be possible to secure a place for installing a temporary enclosure.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to attach a temporary enclosing wall to a retaining wall, a block wall, or the like, if the wall is provided. , To prevent the temporary enclosure from falling down, enabling the installation of the temporary enclosure even if there is no space previously required,
It is to provide a temporary enclosure support bracket.

The supporting bracket 3 has a U-shaped cross section, and is attached to one of the opposing holding pieces 3a. Is provided with a through female screw 6a and a through hole 6b. A bolt 4 is screwed into the penetrating female screw 6a from outside the one holding piece 3a. The number of the bolts 4 is four, and it is preferable that they are arranged evenly in a balanced manner, but the number of bolts 4 may be one or more.

The pressing plate 5 has an insertion rod 5a on one plane.
Are fixed perpendicular to this one plane by welding or the like. The pressing plate 5 is mounted with the insertion rod 5a inserted through the through hole 6b from inside the one holding piece 3a. An external thread may be screwed into this insertion rod 5a. In this case,
Insert the nut 5b from the outside of the one holding piece 3a into the insertion rod 5a.
It is better to screw it on. The nut 5b is inserted into the insertion rod 5a.
Has a role of preventing the pressing plate 5 from falling out of the through hole 6b, and other nuts may be used as long as they have the same role.

On the other hand, a hollow pipe 2 is provided outside the other holding piece 3b opposite to one holding piece 3a of the support fitting 3.
However, it is fixed by welding or the like so that the opening direction P of the U-shaped cross section of the support fitting 3 and the direction of the central axis of the hollow pipe 2 match. The hollow pipe 2 may be a hollow cylinder or a hollow prism. As shown in FIG. 2, a through hole 2 a is provided on a side surface of the hollow pipe 2, and a welding nut 2 b is welded to the outside of the opening of the through hole 2 a, and a bolt is attached to the welding nut 2 b. 8 is preferably screwed from the outside of the hollow pipe 2 and inserted through the through hole 2a, and the number of sets including the through hole 2a, the welding nut 2b, and the bolt 8 is one or more. Is preferred. A female through screw may be provided instead of the through hole 2a and the welding nut 2b.

It is preferable that an elastic member 7 such as a rubber plate is bonded to the inside of the other holding piece 3b of the support fitting 3 with an adhesive or the like, like the pressing plate 5.

Next, a description will be given of a procedure for using the temporary surrounding column support metal fitting 1. As shown in FIGS. 3 and 4, the temporary surrounding column support bracket 1 is used by being attached to a retaining wall 10, a block wall, or the like.

First, the pressing plate 5 is moved so that the distance between the other holding piece 3b of the support fitting 3 and the pressing plate 5 is equal to or larger than the width of the retaining wall 10 or the like. Thereafter, the inner surface of the connecting surface 3c that forms the U-shaped cross section of the support fitting 3 and connects the two opposing holding pieces is brought into contact with the upper surface of the retaining wall 10 or the like, thereby temporarily supporting the support pillar support fitting 1. Is placed on the retaining wall 10 or the like. Thereafter, all the bolts 4 are evenly tightened to apply the axial force of the bolts 4 to the pressing plate 5, and the retaining wall 10 and the like are clamped between the clamping pieces 3b and the pressing plate 5. At this time, the holding wall 10 of the holding piece 3b and the pressing plate 5
It is preferable that an elastic material 7 such as a rubber plate is adhered to the surface that comes into contact with the like so as not to cause scratches, cracks, and the like on the retaining wall 10 and the like. With the above, attachment of one temporary enclosure support pillar 1 to the retaining wall 10 and the like is completed, and thereafter,
In the same manner, the temporary surrounding column support bracket 1 is attached to a required position.

After the mounting of the temporary enclosure support bracket 1 on the retaining wall 10 or the like is completed, the temporary enclosure support 40 is inserted into the hollow pipe 2 and the bolt 8 is tightened to fix the support 40. Thus, the work of erecting the column 40 of the temporary enclosure is completed. In addition,
The bottom 2c of the hollow pipe 2 may be open or closed by welding an iron plate or the like. When the bottom 2c is open, the bottom of the temporary enclosure column 40 reaches the ground, but when the bottom 2c is closed, the bottom of the temporary enclosure column 40 stops at this closed section. When the bottom portion 2c is closed, it is preferable to provide a through hole 2d in the closed portion to discharge water, sand, and the like that have entered the hollow pipe 2.

[0015]

As described above, the temporary enclosure support bracket of the present invention can be mounted on a retaining wall or the like, so that the temporary enclosure support can be set up even if a conventionally required place is not secured. Yes, and since there is no need for supporting materials, there is no protrusion at the foot of the building worker while walking,
Safe, no wasted materials. In addition, the work of erecting the column of the temporary enclosure can be easily performed in a short time because the column is simply inserted into the hollow pipe. In addition, since the temporary enclosure support bracket is sandwiched between the retaining wall and the like by the strong axial force of the bolt, there is no fear that the temporary enclosure support will fall down, and therefore, it is not necessary to periodically check and maintain the support. Further, since an elastic material such as a rubber plate is adhered to a surface of the holding piece and the pressing plate that comes into contact with the retaining wall or the like, the retaining wall or the like is not damaged or cracked.
