Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a joint device for structural members,
More specifically, the present invention relates to a joint device used for joints between structural members such as columns and beams.

[Conventional technology]

For buildings constructed using hollow materials,
A predetermined structure is constructed by connecting a plurality of structural members, such as columns and columns, or columns and beams, to each other in the horizontal or vertical direction. For example, in a joint between columns, a frame-shaped joint material 2 is inserted from the open end surface of the joint pipe material 1 into the inside of the joint pipe material 1, as shown in FIG. The two are fixed by welding so that about 6 mm protrudes from the end surface 1a of the joint pipe material 1.

[Problem that the invention attempts to solve]

In the above-mentioned joint device, when inserting the joint material 2 into the joint pipe material 1, the joint material 2 is
Protruding from the end face of the joint pipe material 1 by about 6 mm relies on experience, so the work has to be very careful, time consuming, and requires experience. There is a problem of becoming scarce.

[Means to solve the problem]

Therefore, this invention aims to make it possible to reliably obtain the protrusion length necessary for welding work without requiring special experience when inserting the joint material into the joint pipe material. It includes a rectangular joint material divided into two in the circumferential direction, a joint pipe material in which the joint material is accommodated in a protruding state from an end face, and a joint plate fixed to this joint pipe material, and the joint material has a plurality of holes on its outer surface. A structure in which a stopper is provided at a position where the joint material can protrude from the end face of the joint pipe material by a predetermined length, and a joint plate of a size that protrudes from the joint pipe material in all directions is fixed to the joint material. It is characterized by:

[Effect]

In this invention, a stopper is provided protruding from the outside of the corner of the joint material, and this stopper touches the end face of the joint pipe material to reliably determine the insertion length of the joint material into the joint pipe material.
Furthermore, there is no effect on quality inspection using ultrasonic waves after completion.

【Example】

Hereinafter, the configuration of this invention will be explained with reference to embodiments shown in the attached drawings. First, in FIGS. 1 and below, reference numeral 10 indicates a joint pipe material formed of a rectangular hollow member made of steel pipe, etc. A joint material 20 is accommodated in the end opening 11 of this joint pipe material 10, and this joint material 20
is fixed to the joint tube 10. This joint material 20 has a shape along the inner edge of the opening 11 of the joint pipe material 10, is approximately square in the figure, and is divided into two joint material units 21, 21 at the circumferential middle part. The corner portion 22 of each joint material unit 21, 21 has a curved surface with a small radius of curvature. The joint parts of the joint material units 21, 21 have a similar shape with step parts 23, 23, and each joint material unit 21, 21 has two corner parts 22. A stopper 24 is formed on the outer surface of the holder by exposing it by pressing, extruding, welding, or the like. This stopper 24 is such that the joint material 20 is the joint pipe material 10.
When inserted into the interior, it rests on the end surface of the joint material 10 and controls the protrusion dimension from this end surface 12.The end surface of the stopper 24 hits the end surface of the joint material 10, and the required protrusion length L of the joint material 20 is is retained. Further, the joint material 20 has a corner-shaped 45-degree inclined surface 25 formed on the inner edge of the end opposite to the protruding end, and when welding the joint material 10 with the joint pipe material 10, the position of the tip of the welding rod is is now visible. With a part of the joint material 20 protruding from the end surface of the joint pipe material 10, the joint material 20 is welded to the joint pipe material 1.
0, and a joint plate 30 having a flange-like projecting portion 31 on the end face of the joint material 20 is integrated by welding. In this case, the stopper 24
As a result, one end of the joint material 20 and the end of the joint pipe material 10 protrude evenly, so the joint material 20 and the joint plate 30 maintain an angle of exactly 90 degrees, and therefore the columns can be joined straight, and welding is not required. is easily done. Furthermore, the joint material 20 is also inserted into the end of the hollow pillar material 40, and at this time, the stopper 24 rests on the opening edge 41 of the pillar material 40, and the joint material 20 protrudes from above the opening edge 41. In this state, the joint pipe material 10 of the joint material 20 is integrated by welding.
The joint plate 30 fixed to is integrated by welding. As shown in FIG. 1, a joint material 20 fixed to a joint pipe material 10, a joint material 20 fixed to a joint pipe material 10,
A joint plate welded and fixed to this is located, and the column material 40
In addition to extending in the length direction, by positioning the ends of the beam material 50 against the overhanging parts 31, 31 of the joint plate 30, it is easy to integrate the two, and the structure using the beam material 50 can be extended in all directions. can be used for the development of In particular, since the stopper 24 is located on the curved surface part of the corner part 22 of the joint material unit 21 constituting the joint material 20, this curved surface part is Since it is outside the target area of the sonic test, it will not falsify the test results.

[Effect of the idea]

As is clear from the above description, according to the joint device for structural members of this invention, when the joint material is inserted into the joint pipe material, a plurality of stoppers are formed on the outer circumferential surface of the joint material, so that the end face of the joint pipe material The protrusion length of the joint material can be reliably maintained, making welding to the joint plate easier, and the stopper does not interfere with ultrasonic inspection during welding inspection.
