Problems solved by technology

For example, when the object to be assembled is a shelf, when the pipe P1 described in the former publication or the joint described in the latter publication is mounted on the pipe but the accuracy of the height dimension is poor, it is easy to cause the shelf to be damaged after assembly. Shaking and other problems
It is difficult to adjust the height accurately when the work is performed by the operator's feeling in this way.

[0043] figure 2 It is a perspective view for explaining the 1st Example of the pipe joint of this invention, and shows the state which inserted the pipe joint. This figure is related to figure 1 (a) Corresponding. image 3 It is the perspective view of this 1st Example, FIG.4(a) is the top view, FIG.4(b) is the front view, and FIG.4(c) is the right side view.

[0044] The pipe joint 11 is composed of two split joints, a 1 / 4 core barrel type split joint 111 and a 3 / 4 core barrel type split joint 112 . The 1 / 4 core cylinder type spliced ​​joint 111 is composed of a 1 / 4 cylinder side wall portion 3A of the core cylinder portion 3 having a circular arc with a central angle of 90 degrees, and from both ends of the cylinder side wall 3A to the cylinder side respectively. The semi-tubular protruding half-pipe portions 44, 44 are formed of semi-tubular protruding wall portions at an angle of 90 degrees. The other 3 / 4 core barrel type spliced ​​joint 112 is composed of a 3 / 4 barre...

Abstract

A pipe joint, comprising a plurality of split joints combined with each other forming a core tube part allowing pipe materials to be inserted therein in the directions orthogonal to each other and projected tube parts formed projectedly from the core tube parts outward, wherein bolt holes are formed through the projected tube parts at the positions near the core tube part, and hole parts are formed in the side faces of the core tube part, whereby the split joints can be fixed to the pipe materials with bolts and nuts through the bolt holes.

Description

【Technical field】 [0001] The present invention relates to a pipe joint for connecting pipes of various lengths and an assembly using the pipe joint. 【Background technique】 [0002] Conventionally, with various lengths of pipe fittings and joints, the cylindrical portion is formed by combining a variety of spliced ​​joints with a size and shape suitable for the pipe receiving portion of the pipe fitting as a composite assembly between the ends of the pipe fittings or at the intermediate position of the pipe fittings. , insert a pipe into the cylindrical portion, and fix it with bolts and nuts in a sandwiched state. A structure in which a plurality of pipes can be freely assembled vertically and horizontally by using this structure is known. [0003] As an example of such a prior art, a method of connecting a pipe and its joint described in Japanese Patent Publication No. Sho 53-25170 are: In the spliced ​​joint composed of the joint part and the semi-tubular pipe part conne...
