As shown in FIG. 1, the lower end of the column 2 for supporting the scaffold plate 4 is inserted into the main body 11, and the front of the main body 11 (the side opposite to the building). (A surface 11T) and a portion 11B near the lower end portion and a portion 11B near the lower end portion are fixed by set screws. Thereby, the column 2 is held in a vertical state.

The column 2 supports a scaffold plate 4 via a bracket 3 attached to a position at a predetermined height of the column 2. The bracket 3 includes a horizontal portion 31 on which the scaffold plate 4 is placed, and a cross stick 32. At both ends of the horizontal portion 31, hook portions 311 protruding downward are provided. The support 2 has a pocket 2 at a predetermined height.
The hook 311 at one end of the bracket 3 is inserted into the pocket 21 and locked. The other end of the bracket 3 is fixed to the upper end of a staff 32, and the lower end of the staff 32 is attached to the pocket 21 of the support 2.
, Thereby receiving the load of the scaffold plate 4. The pockets 21 of the support column 2 are provided stepwise at a plurality of height positions, so that the mounting position of the bracket 3 can be changed stepwise. In addition, the pocket portion 21 has four front, rear, left and right
Since the bracket 3 is provided so as to protrude in the direction, the direction of the bracket 3 can be changed to the front, rear, left and right, and therefore, it is possible to easily cope with, for example, a protruding corner, a entering corner, etc. of a building.

The upper and lower mounting pieces 12T and 12B are steel plates, and are the back surface of the main body 11 (the surface facing the building).
Are welded so as to be perpendicular to the main body 11 at a portion near the upper end and a portion near the lower end. The mounting pieces 12T, 12
The free end side of B is formed wider than the fixed end side, and the mounting pieces 12T and 12B are generally T-shaped as a whole. Bolt insertion holes are provided at two positions arranged in the width direction on the free ends of the mounting pieces 12T and 12B. On the lower surface of the lower mounting piece 12B, a locking piece 121B made of a steel plate is provided to protrude downward.

The free end side of the upper mounting piece 12T is overlapped on the upper surface of the lower flange 5B of the floor beam 5 of the building made of H-section steel and fastened with bolts and nuts. An anchor bolt 61 of the foundation 6 of the building is inserted into a bolt insertion hole provided on the free end side of the lower mounting piece 12B, and is fastened with a nut. At this time, the lower mounting piece 12B
Is in contact with the outer surface of the foundation 6, so that when the worker is on the scaffolding plate 4, the mounting bracket 1
It receives a horizontal load applied to the lower end side.

FIG. 1 shows the mounting bracket 1 at one location and its mounting structure. The mounting bracket 1 is mounted around the building at appropriate intervals in the same manner as described above.

With the above-described mounting structure, the main body 11 is stably mounted on the lower end (floor 5) and the foundation 6 of the building frame. In the example shown here, first, the upper floor of the building is constructed on the ground, and then the upper floor is pulled up by a hydraulic jack, and the lower floor is constructed underneath. We are going to build. For this reason, as shown in FIG. 1, a gap s of several tens cm is formed in advance between the lower surface of the floor beam 5 in the upper floor portion and the upper surface of the foundation 6 by a spacer P, a bundle (not shown), and the like. With this, equipment such as a hydraulic jack is carried in, workers enter and exit, and the like. Therefore, the interval between the upper and lower mounting pieces 12T and 12B of the mounting bracket 1 is set to be substantially equal to the gap s.

According to the mounting bracket 1, since it is attached to the lower end portion of the frame of the building and the foundation 6, it is not necessary to remove the temporary scaffolding even when performing joint work on the building. It does not take. Further, since the mounting structure is simple, the scaffold can be easily installed and removed.

[0019] Furthermore, since it can be mounted in a stable state irrespective of irregularities on the ground, it is safe. Also, because it does not require much space for installation,
It can be easily installed even if there is not enough space around the building.

Furthermore, as described above, the mounting is easy and the number of parts is small, so that the working process is simple and the cost is not high.

In the present invention, various modifications may be made in addition to the mounting bracket 1 shown in the above embodiment. For example, the main body may be configured to be expandable and contractable by a nesting structure or the like so that the distance between the upper and lower mounting pieces can be adjusted, so that it is possible to cope with mounting parts having different sizes.

The mounting bracket of the present invention can be used for purposes other than mounting a temporary scaffold. FIG. 2 shows an example of a temporary mounting base for building components using the mounting bracket of the present invention.

The temporary mounting base 7 for building components shown in FIG. 2 includes the mounting bracket 1, the bracket 3A, and the plate 8. FIG. 1 shows the mounting bracket 1 and its mounting structure.
The bracket 3A is basically the same as the bracket 3 shown in FIG.

As shown in FIG. 2, the bracket 3A is attached to a substantially intermediate portion of the main body 11 of the attachment 1 by a clamp 13. Clamp 13 is pocket part 1
The hook 311A of the bracket 3A is inserted and locked in the pocket 131. The lower end of the staff 32A of the bracket 3A abuts below the pocket 131 in the main body 11 of the mounting bracket 1.

The plate 8 is horizontally placed and supported on the bracket 3A and another bracket (not shown) provided next to the bracket 3A. As the plate 8, any plate material or panel material can be used as long as it has a strength enough to temporarily store building components such as an outer wall panel. For example, a scaffold plate for the temporary scaffold can be used. 4 may be used as it is.

When using the temporary mounting base 7, for example, as shown in FIG. 3, the lower end of the outer wall panel 9 is placed on the temporary mounting base 7, and the upper end is placed on the frame of the building C. By doing so, the outer wall panel 9 can be temporarily placed in front of the mounting position. This facilitates the work of attaching the outer wall panel 9 to the frame of the building. In addition, the temporary mounting base 7 can be assembled using the mounting bracket 1 attached to the floor beam 5 and the foundation 6 of the building C as it is in order to perform work at a high place by the temporary scaffold. In other words, the mounting bracket 1 can be shared by the temporary scaffold and the temporary mounting base in a state where it is mounted on the frame of the building C and the foundation 6.

The temporary mounting base 7 has an outer wall panel 9
In addition, arbitrary building components can be placed.
