Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a butter material connecting device for fixing butter materials in parallel, which are used for supporting formwork and the like.

[Conventional technology]

Is it possible to use the seed Bataneo as a light source? Tora is made of lightweight shaped steel, which can be used singly or in pairs, but since Bata material is of a fixed length, it is cut each time according to the size of the formwork to be formed. It is used by cutting it to a predetermined length or adding it by connecting it.

Cutting and splicing Bata wood is a standard work at present, so
Not only does it require a lot of work, but it also has the disadvantage of increasing the construction cost of the formwork, as there are many cut-off parts of the batten, which results in wasted materials.

Therefore, a butter material as disclosed in Japanese Utility Model Application Publication No. 58-5541, for example, has been proposed as a material that improves the deficiency α of the butter material.

[Problem that the invention seeks to solve]

The above-mentioned improved idea uses a connecting material with a 7-run part that contacts a part of the outer peripheral surface of the two pipes to be joined, and has a structure in which the pipe material and the 7-run part are fixed with screws, etc. There is. However, with the Bata material of this invention, the pipe material and the connecting material are attached together using screws, etc., so when joining, screw holes must be drilled at the positioning points each time, requiring a lot of screwing work. However, the problem is that the work is quite troublesome. Also, since the axes of the two joined pipes are separated from each other, they will twist under load.
On the other hand, the connecting material of this invention has low rigidity, cannot prevent twisting, and has low strength, resulting in problems such as the need to increase the number of batters used in the formwork. There is a point.

The present invention solves the drawbacks of the conventional butterfly material connections, and makes it possible to extremely easily connect butterfly materials to each other at any desired position, and also to ensure strong bonding with almost no twisting of the butterfly materials. The purpose of this invention is to provide a butter material connecting device that allows easy connection.
