Description

[Detailed description of the invention] This invention relates to a joint structure for easily assembling H-section steel materials on site.

In the past, many joint structures of this type have been devised, but none of them are particularly suitable for H-beam steel. Normally, H-beam steel and joint members are connected by bolts and nuts, but the threads of the bolts and nuts are exposed at the connection.
It made the exterior look unsightly.

This invention solves the problems of the conventional example described above, and its purpose is to use a box-shaped joint member and store the threaded part of the bolt and nut in the box, so that the bolt can be tightened. To provide a joint structure in which a threaded part or a nut is not exposed and the joint member is used as an end cap to provide a sense of unity with the H-beam steel.

Hereinafter, the configuration of this invention will be explained with reference to the drawings showing one embodiment.

FIG. 1 shows the joint structure of this invention applied to a four-sided joint of beams 1, 1, girders 2, and columns 3 made of H-section steel. Reference numeral 4 denotes a joint member in the shape of a cubic box, with one side open and mounting holes 5 provided on each of the other five sides. A plate body 7 with mounting holes 6 is welded to the tips of each of the beams 1, 1, girder 2, and column 3. Bolts are passed through the mounting holes 7 into the mounting holes 5 of the joint member 4, and the joints are attached. The beam 1, girder 2, and column 3 are attached to the joint member 4 by fitting and tightening a nut into the threaded portion of the bolt from inside the member 4. As a result, the head 8 of the bolt is exposed, but the threaded portion and nut of the bolt are housed inside the joint member 4 and are not exposed. Reference numeral 9 denotes a rainproof cap, which has a locking piece 10 protruding from the bottom, and is placed over the open surface of the joint member 4. Furthermore, the mounting hole 5 of the joint member 4 to which the H-shaped steel material cannot be mounted.
are hidden with a resin cap, etc.

FIG. 3 shows the joint structure of this invention applied to a three-way connection between a beam 1, a girder 2, and a column 3 made of H-shaped steel. Lighting equipment 1 instead
1 is provided.

In the above embodiments, a four-way connecting portion and a three-way connecting portion have been described, but the H-shaped steel material is attached to the joint member 4 in the same manner in the case of a two-way connecting portion and a five-way connecting portion. Further, the mounting holes 5 provided in the joint member 4 are not limited to five faces, and may be provided only on the face to which the H-beam steel is mounted. Furthermore, although a rainproof cap 9 and a lighting fixture 10 are provided in the above embodiment on one open side of the joint member 4, other appropriate equipment may be provided as required.

Therefore, if the joint structure of this invention is used, the double building 12 shown in FIGS. 4 to 6,
Various types of multi-row buildings, such as the triple-row ridge 13 and the double-row ridge 14, having a large number of three-way connecting parts, four-way connecting parts, and five-way connecting parts can also be easily produced.

Since this idea is structured as described above, H
The steel section and the joint member are transported separately to the site and then assembled easily, and the bolt threads and nuts are not exposed, and the joint member acts as an end cap and is integrated with the H section steel. It is something that you can experience and has excellent practical effects.

Claims (1)

[Scope of utility model registration request] One side of the cubic box-shaped joint member 4 is opened, mounting holes 5 are provided on the other appropriate faces, and a plate 7 with mounting holes 6 provided at the tip of an H-beam steel is welded. The H-shaped steel material is attached to the joint member 4 by passing a bolt from the attachment hole 6 into the attachment hole 5 of the joint member 4, and fitting and tightening a nut into the threaded part of the bolt from inside the joint member 4.
