Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting bracket for a handrail post when a temporary handrail is installed in a construction work.

[Prior Art] Conventionally, when installing a temporary handrail, a guard post in which the handrail support fitting and the handrail support are integrally formed, or a temporary member having a function similar to that, or a clamp fixture and a single pipe Etc. were used in combination.

[Problems to be Solved by the Invention] In the above-mentioned conventional method, a method of disposing a temporary handrail on the H steel material on the outer periphery of a building is disclosed in order to prevent workers, building materials, and the like from falling, particularly in steel frame construction. However, in that case, when installing the mounting bracket of the handrail support, the worker must work at or below the feet, so when performing work in high places, there is a risk of falling or other disasters. There is a possibility that it may happen and it is not safe.

When placing slab concrete on the deck plate, a skirting board is attached to the outer end surface of the H steel material on the outer periphery of the building to prevent the concrete from flowing out, but at that time, dismantle all temporary handrails that have already been installed. It is necessary to pour concrete and install temporary handrails again after pouring.

It takes a lot of time and effort to install and remove the handrail support pillar and the mounting bracket for the handrail support pillar, resulting in a reduction in work efficiency.

Further, there is a problem in that safety is not reliable because a temporary handrail for preventing falling cannot be installed on the outer periphery of the building when the slab concrete is poured.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems of the related art, and an object thereof is to allow an operator to easily and safely attach a temporary handrail, particularly a handrail support fitting. It becomes possible to dismantle the handrail for temporary installation during the placing of slab concrete, and to provide a highly safe handrail support fitting without the trouble of installation after placing.

As a means for this, a hollow cylindrical mounting portion having a notch for preventing slippage is integrally formed on a pedestal protruding in a brim shape.

[Operation] With the above structure, since the pedestal and the mounting portion are integrally formed, the pedestal and the mounting portion can be self-supporting, and therefore can be easily mounted on the H steel material by welding or the like.

Since the mounting portion is formed in a tubular shape, the handrail support can be easily mounted.

Since the handrail support bracket and the handrail support are covered with paper tubes and the like, the time and effort for removing the handrail support and handrail support mounting bracket during concrete placement are eliminated, so that disassembly of the temporary handrail is unnecessary.

Also, since the temporary mounting handrail is no longer needed due to the hollow tubular mounting part, the strength of the slab concrete can be reduced by filling the holes with mortar after removing the handrail support post and the handrail support fittings. The above-mentioned conventional problems are solved so as not to have any effect on the above.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of the present invention.

(1) is a mounting bracket main body, which is integrally formed with a hollow cylindrical mounting portion (1b) on a pedestal (1a) protruding like a collar.

In addition, a notch (3c) is provided at the upper end of this cylindrical mounting part to prevent the single pipe used as the handrail support from coming off.

Next, a description will be given of an example of using the mounting bracket for the handrail support pole for construction according to the first embodiment of the present invention.

FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6 are a side view and a partial cross-sectional view showing a usage example of the first embodiment of the present invention.

As shown in FIG. 2, the main body (1) is installed on the H steel material (C), and the pedestal (1a) is welded and fixed to the H steel material (C).

Next, as shown in FIG. 3, the cylindrical mounting portion (1
The b) is covered with a paper tube (A) slightly longer than the mounting part, and the single tube (B) is inserted therein so as to fit into the tubular mounting part (1b) of the main body (1). Similarly, as shown in FIG. 4, the main body (1), the paper tube (A), and the single tube (B) are installed at predetermined intervals, and the temporary handrail is assembled by using the single tube (B) and the like as pillars.

Then, as shown in FIG. 5 and FIG. 6, slab concrete (E) was placed without disassembling the temporary handrail, and when the temporary handrail became unnecessary, the single pipe handrail (B) Can be disassembled to remove the paper tube (A), and then the hole (G) can be filled with mortar (F) for processing, and the main body (1) can be buried.

[Effect of the Invention] As described in detail above, according to the mounting bracket for the handrail prop for construction of the present invention, since the pedestal and the mounting portion are integrally formed, they stand independently as a single item. Since it can be installed on the H steel by welding or the like, the safety of the operator is improved.

Moreover, since the mounting portion is formed in a tubular shape, it is easy to mount the handrail support pillar, and by covering the mounting bracket and the handrail support pillar with a paper tube or the like, the handrail support pillar at the time of placing concrete,
Since there is no need to remove the handrail support bracket, the work efficiency can be greatly improved.

Also, since the mounting part is a hollow cylinder and the handrail is no longer needed, after removing the handrail props and handrail prop fittings, the holes are filled with mortar so that the strength of the slab concrete is little. It is possible to obtain a mounting bracket for a handrail strut that is practically useful so as not to affect it.
