Abstract

(57) [Summary] (with amendments) [Purpose] To provide a mounting bracket that can easily and reliably attach a single pipe for a scaffold base and a suspension chain when constructing a suspended scaffold in construction work. [Structure] A clamp fitting 1 and a chain support fitting 2 are rotatably connected.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed for use under scaffolding when constructing suspended scaffolding such as S construction and SRC construction in construction work. Concerning mounting hardware for underground pipes and hanging chains.

0002

[Conventional technology]

Conventionally, it is used as a steel frame material to construct work scaffolds such as S construction and SRC construction. After the H-shaped steel was erected, a single tube for the scaffold base was wrapped around the H-shaped steel approximately 2m below the H-shaped steel. A suspension system in which a scaffold is constructed by suspending a suspension chain and constructing a scaffolding board on top of the single pipe. A construction method for scaffolding is disclosed.

0003

[Problem that the idea aims to solve]

In the above conventional method, the single pipe for the scaffolding base, which is suspended below the H-shaped steel, is connected to the suspension chain. Because it is wrapped directly around the suspended scaffold, vibrations occur due to the passage of workers after the suspended scaffolding is constructed, and There are problems such as the pipe slipping out of the chain.

0004

[Means to solve the problem]

This idea was devised in view of the above-mentioned conventional problems, and its purpose was to We provide hanging scaffold mounting hardware that securely grips pipes and makes it easy to attach chains and single pipes. It is something that

[0005] As a means of achieving this, a clamp fitting for supporting the single tube and a chain are wrapped around and supported. It is characterized by being rotatably coupled to a chain support.

[0006] With the above structure, the single pipe for scaffolding base is supported by the clamp fitting for supporting the single pipe. It has a secure grip and is easy to install. In addition, wind the hook attached to the end of the hanging chain through the chain support. Easy to install as it can be installed by simply hooking it onto the chain at the desired position. This solves the conventional problems mentioned above.

【Example】

FIG. 1 is a perspective view showing an embodiment of the mounting bracket of the present invention, and FIG. 2 shows the structure of the embodiment. It is a perspective view showing a component. As shown in Fig. 2, it consists of a clamp fitting 1 and a chain support 2. A hole 1 large enough to screw the mounting bolt 2d of the chain support 2 into the bottom of the pump fitting 1. Drill a. The chain support 2 can be slid on the inside of the U-shaped portion 2a and the opposite side of the U-shaped portion 2a. The U-shaped portions 2b that can be connected are connected by a connecting shaft 2c, and in that case, the U-shaped portions 2b Screw together so that it slides at any angle around the axis. As shown in FIG. 1, the mounting bolt of the chain support 2 is inserted into the hole 1a of the clamp fitting 1. Screw in the bolt 2d, and then screw the mounting nut 2e into the mounting bolt 2d. It is configured to be rotatably coupled to the clamp fitting 1.

[0008] FIG. 3 is a partial sectional view showing how the mounting bracket according to the embodiment of the present invention is used. Then, attach the tip of the hanging chain B wrapped around the H-shaped steel A to the U-shaped part 2b of the chain support 2. At the same time, after gripping the single tube D for scaffolding base with the clamp fitting 1, Hang the hook part C on the hanging chain B and fix it. In the same way, attach the hanging chain B to the single pipe support clamp, and then Assemble the single pipes D for the scaffolding base, place the scaffolding boards E in the required positions, and construct the suspended scaffolding. It is something to do.

[0009]

[Effect of the idea]

As explained in detail above, according to the mounting bracket for suspended scaffolding for construction work of this invention, Clamp fittings for supporting single pipes ensure secure grip to support single pipes for scaffolding. It is easy to install, and is effective in ensuring safety and improving work efficiency. In addition, wind the hook attached to the end of the hanging chain through the chain support, Easy to install as it can be installed by simply hooking it onto the chain at the desired position. , a suspended scaffold for construction work that is practically useful and can be expected to improve work efficiency as well as the above. You can get the mounting hardware.
