Description

[Detailed Description of the Invention] This invention relates to a temporary scaffolding clamp used to tighten scaffolding members at a construction site.

In this type of clamp, the holding body is rotatably attached to one end of the holding body, and a bolt is rotatably attached to the other end of the holding body, and the holding body is tightened with this bolt. Therefore, a structure in which the scaffolding member is held between the legs is common. However, with this configuration, since the scaffolding member is held between the holding body and the holding body part, only the scaffolding members of a certain diameter can be tightened, and the tightening may be incomplete or the scaffolding members may wobble after long-term use. There were some difficulties, such as the occurrence of

This invention was devised in order to solve the above-mentioned difficulties.It is especially used for scaffolding members made of square pipes, and the purpose is to provide a scaffolding member of different diameters that can be fastened together and that can be firmly fastened together. purpose.

The following description will be made based on the illustrated embodiment. 1
shows a clamp of this invention. This clamp 1 is made up of two clamps fixed back to back at right angles, and each clamp has a holding body 2, a holding body 3, and a bolt. It consists of 4.

The holding body 2 is formed in an L-shape, and the inner surface in contact with the scaffold member A has a length that is in contact with half the circumference of the scaffold member. A notch 5 for inserting a bolt is provided at the tip of the attachment body 3.

On the other hand, the other end of the holding body 2 is further bent at a right angle to form a bolt pivot attachment part 6, and a bolt 4 is rotatably pivoted to this bolt pivot attachment part 6. The bolt pivot portion 6 is provided with a slit 7 extending diagonally with respect to the bolt tightening direction. The bolt 4 is pivotally attached by a pin 8 passing through the slit 7, and the pin 8 can slide and move along the slit 7.

The bolt 4 has a rectangular base 9 which is a pivotally connected part to the pin 8, and the surface of the base 9 that contacts the scaffolding member A is slightly protruded inward from the bolt body, and has a smooth inner surface. It is formed. Further, the inner surfaces of the holding body and the bolt that are in contact with the scaffolding member A each have a length that is in contact with a quarter circumference of the scaffolding member.

In use, the scaffolding member A is held between the holding body 2 and the holding body 3, the bolt 4 is inserted into the notch 5 at the tip of the holding body 3, and the nut 4a attached to the bolt 4 is inserted.
to tighten the scaffolding member A. In this case, not only the scaffolding member A is held between the holding body 2 and the holding body 3, but also the base 9 portion of the bolt 4 comes into contact with the scaffolding member A. Depending on the diameter of the scaffolding member A, for example, when tightening the scaffolding member A with a larger diameter as shown in FIG.
The bolt 4 and its base 9 move downward, and the bolt 4 and its base 9 move to a position where they come into contact with the side surface of the scaffolding member A, and the holding body 2, the holding body 3, and the base 9 hold the scaffolding member A. to hold. In addition, as shown in Fig. 2, when tightening the scaffold member A with a smaller diameter, by tightening the nut 4a attached to the bolt 4, the pin 8 moves upward in the slit 7, and the bolt 4 and its base 9 move inward and abut against the side surface of the scaffolding member A. The scaffold member A is held between the holding body 2, the holding body 3, and the base 9.

This invention has the above-mentioned structure, and the bolt pivoting part of the holding body is provided with a slit extending diagonally, and the pin to which the bolt is pivoted is formed so that it can move within this slit. The bolt moves inward or outward depending on the diameter, and the base of the bolt protrudes slightly inward from the bolt body and has a smooth inner surface, so the movement of the bolt causes this base to move into the scaffolding member. Since the scaffolding member is brought into contact with the holding body and the holding body, and the scaffolding member is tightened, it can be used with scaffolding members of different diameters, and there is no need to use other types of clamps at the site.

In addition, unlike conventional scaffolding members, the scaffolding members are clamped and tightened by the holding body and the base of the bolt with a smooth inner surface in addition to the holding body, so it is firmly tied and can withstand long-term use. It does not cause any stickiness.
