DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary mounting device used for mounting various temporary members such as safety handrails, safety nets or work scaffolds at a construction site of a building.

[0002]

2. Description of the Related Art Conventionally, when attaching a temporary member such as a temporary safety handrail, a clamp is attached to an outward horizontal edge or a vertical edge of an existing steel die, and the temporary member is attached to the clamp. Therefore, the temporary member cannot be attached by the clamp unless the horizontal and vertical edges are directed outward from the die steel.

[0003] For example, in a wooden prefabricated house, lightweight steel as a beam material for supporting a floor panel is provided around a floor opening (a stair mounting opening or the like) on the second floor so that a horizontal edge portion thereof faces inward. It is arranged, but in this case, even if an attempt is made to attach a safety handrail or the like for preventing a worker from falling along the opening, the horizontal edge of the section steel is present inward below the floor plate. Therefore, it is not possible to attach a safety handrail or the like using the horizontal edge portion.

[0004] The present invention utilizes the inward horizontal edge portion of the shape steel when the shape steel is provided around the stair mounting opening or the like so that the horizontal edge portion faces inward as described above. It is another object of the present invention to provide a temporary mounting device capable of mounting a safety rail or the like for preventing a fall around the opening.

[0005]

In order to achieve the above object, a temporary mounting device according to the present invention comprises a U-shaped main body which is fitted outwardly to an inward horizontal edge portion of a shape steel, and a U-shaped main body. A holding member which is located between a pair of upper and lower horizontal legs of the main body and which is attached to the U-shaped main body so as to be able to ascend and descend within a certain range by a vertically long hole and a fixing tool penetrating therethrough; The member is formed with a clamp mounting portion projecting laterally outward from the tips of the upper and lower legs of the U-shaped main body.

The pressing member has a longitudinal section formed in a gate shape, and the lower leg of the U-shaped main body is loosely fitted between both side plates. It is preferable that a mounting plate portion sandwiching a vertical connecting portion connecting both legs is continuously provided, and both mounting plate portions are mounted on the U-shaped main body by the elongated hole and the fixing tool.

The holding member 11 is formed such that the upper plate 11a and the side plates 11b, 11b have a gate-shaped vertical section, and the lower leg 8a of the U-shaped main body 7 is provided between the side plates 11b, 11b. While being loosely fitted, both side plates 11b, 11b
A mounting plate portion 20 sandwiching the vertical connecting portion 13 of the U-shaped main body 7 is integrally connected, and the mounting plate portion 20 is provided with the elongated hole 9.
Is formed and fixed to the U-shaped main body 7 by the elongated hole 9 and the fixture 10 so as to be movable up and down within a certain range. Further, the upper plate 11 of the pressing member 11
The end of “a” opposite to the mounting plate 20 is the clamp mounting portion 12.

The clamp 3 mounted on the clamp mounting portion 12 has a U-shaped main body 21 similar to the U-shaped main body 7 of the temporary mounting device 2, and the lower leg 21a of the U-shaped main body 21 has an upper side. A fastening screw shaft 23 for clamping and fixing the clamp mounting portion 12 between the leg portion 21b is provided, and a disc spring 24 is attached to the tip of the screw shaft 23. The column holding rod 4 is fixed to a vertical connecting portion 21c connecting the upper and lower legs 21a and 21b, and the lower end of each handrail column 6 of the safety handrail 5 is fitted to the column holding rod 4. Fixed.

In using the temporary mounting device 2 having the above-described configuration, the holding member 11 is fitted into the U-shaped main body 7, and both mounting plate portions 20 of the holding member 11 are vertically connected to the U-shaped main body 7. The bolt 10a of the fixture 10 is passed through the elongated hole 9 and the bolt insertion hole 19 with the portion 13 interposed therebetween,

The horizontal edge part 1a is inserted between the vertical edge part a and the edge of the horizontal edge part 1a and the vertical connection part 13 of the U-shaped main body 7 is brought into contact with the horizontal edge part 1a. then,
The fastening screw shaft 14 is fastened, the upper plate 11b of the holding member 11 is pressed and fixed to the lower surface of the horizontal edge portion 1a via the disc spring 15, and the wing nut 10b of the fixture 10 is tightened to be temporarily mounted. The device 2 is fixed to the horizontal edge 1a.

By fixing the temporary mounting device 2 to the inward horizontal edge portion 1a of the section 1 in this way, the section 1
Then, the clamp mounting portion 12 of the holding member 11 projects outward on the opposite side of the U-shaped main body 7 by inserting the vertical wall portion 1b. Therefore, the outwardly protruding clamp mounting portion 12
The main body 21 of the clamp 3 is fitted to the
The clamp 3 is fixed to the clamp mounting portion 12 by tightening the clamp 3. In this case, when the fastening screw shaft 23 is fastened, the clamp mounting portion 12 is pressed against the upper leg portion 21b of the U-shaped main body 21 by the disc spring 24 at the tip, whereby the clamp 3 is fixed to the clamp mounting portion 12. become. Then, the handrail support 6 of the safety handrail 5 may be fitted and fixed to the support rod 4 attached to the clamp 3.

In this embodiment, the holding member 11 is formed by the fastening screw shaft 14 provided on the lower horizontal leg 8a of the U-shaped main body 7 and the fixing tool 10 penetrating the elongated hole 9 of the vertical connecting portion 13.
Is fixed to the U-shaped body 7, but the fastening screw shaft 14 is not essential to the present invention, and
The holding member 11 may be fixed to the U-shaped main body 7 by itself.

[0015]

In the temporary mounting device according to the first aspect of the present invention, the U-shaped main body is fitted to the inward horizontal edge portion of the mold steel, and the upper horizontal leg portion of the U-shaped main body and the holding member are held. The holding member is fixed to the U-shaped main body by a fixing tool with the horizontal edge portion sandwiched between the member and the temporary mounting device is fixed to the horizontal edge portion.

By fixing the temporary mounting device to the inward horizontal edge portion of the section steel in this way, the clamp mounting portion of the holding member projects outward on the side opposite to the U-shaped body with the vertical wall section of the section steel interposed therebetween. become. Therefore, if a clamp is mounted on the outwardly protruding clamp mounting portion, various temporary members such as safety handrails can be mounted by the clamp.

Further, as in claim 2, the pressing member is
