Description

[Detailed description of the device]

[0001]

[Industrial field of application] This invention is for constructing a temporary chain suspension scaffolding for handrails at a desired height of a chain for suspending a passageway of the suspension scaffolding so that an operator can safely pass therethrough. The present invention relates to a mounting bracket for mounting a handrail pipe on a chain for suspending a pipe in that case.

[0002]

2. Description of the Related Art Conventionally, a handrail pipe has been attached to a hanging chain by winding a metal wire.

[0003]

[Problems to be Solved by the Invention] In the above conventional method,
Since the handrail pipe is attached to the hanging chain by winding a metal number wire, etc., side slippage occurs when the worker comes into contact with the handrail pipe during the installation work or after the installation, and it falls. Cause Further, there is a problem in that the worker is uneasy in terms of strength as a mounting tool for supporting the handrail in a place where a worker frequently comes and goes, only by winding the number wire.

[0004]

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to have strength as a mounting tool for supporting a handrail, and also during mounting work of a handrail pipe. Alternatively, the present invention provides a handrail pipe mounting bracket that can be securely attached without causing side slippage when an operator comes into contact with the handrail pipe after attachment.

As a means for this, a bolt is provided so as to protrude from the bottom surface of the clamp fitting, and a recessed chain engaging portion capable of advancing and retracting and a nut for tightening are attached to the bolt.

With the above structure, a bolt is projected on the bottom surface of the clamp metal fitting, and a concave chain locking portion capable of advancing and retracting and a tightening nut are attached to the bolt, so that a desired hanging chain can be obtained. The main body can be attached to the hanging chain by inserting the protruding piece on one side of the concave chain locking part into the hollow part of one wheel and tightening the tightening nut, and the handrail pipe is attached with the clamp metal fitting. It is possible to solve the above-mentioned conventional problems.

The main body is attached to the hanging chain by fitting the protruding piece 3a on one side of the concave chain engaging portion 3 into the and tightening the tightening nut 4. As shown in FIG. 5, the handrail pipe C is attached with the clamp metal fitting 1, and the attachment metal fitting and the handrail pipe of the present invention are similarly attached to the hanging chain at the required intervals to remove the handrail of the passage of the suspension scaffold. To construct.

Next, another embodiment of the present invention will be described. Sixth
The drawing is a partial cross-sectional view showing another embodiment of the handrail pipe mounting metal fitting for the construction work hanging scaffolding according to the present invention. When the nut 14 is tightened on the bottom surface of the clamp metal fitting 1, the bolt 12 is The elongated holes 11b and 11 are formed so that the protruding pieces 13a and 13b at both ends of the recessed chain locking portion 13 that can move forward and backward are fitted.
By providing b, it is possible to prevent rattling when attached to the hanging chain and to realize more stable attachment to the hanging chain.

[0010]

As described in detail above, according to the handrail pipe fitting of the suspension scaffold for construction work of the present invention, a bolt is provided on the bottom surface of the clamp fitting, and the recessed type is capable of advancing and retreating to the bolt. Since the chain locking part and the tightening nut are attached, the protruding piece on one side of the concave chain locking part is fitted into the hollow part of the desired one wheel of the hanging chain, and the tightening nut is tightened. The main body can be attached to the hanging chain by tightening it, and the handrail pipe can be attached with the clamp metal fittings, so when the handrail pipe is installed or after the worker comes in contact with the handrail pipe. Without skidding on
A handrail pipe fitting that is useful for practical use, such as a reliable attachment for work safety and reliability, and a reliable support for the handrail in terms of strength. Obtainable.
