Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel structure, reinforcing bars, and a steel structure, particularly a structure for constructing columns and beams of buildings by combining relatively thick sections.

We have developed a variety of steel structures in which channel steel is butted against each other to form columns with square cross sections, and H-beams are used for beams.

By the way, although the above structure is suitable for high-rise buildings, it is not suitable for low-rise buildings, especially SRC structures, since it is difficult to arrange reinforcing bars.

This invention uses channel steel, and by arranging them facing each other at intervals, the arrangement and fixation of reinforcing bars and beam steel joint plates are improved.The details will be explained with reference to illustrated embodiments.

In Figures 1 to 3, a column steel frame 1 is constructed by arranging channel steels 2, 2 facing each other at intervals, and a joint plate 3 having a cross-shaped plane is arranged at the beam attachment position. ,
One opposing flange 4 of the joining plate 3 is arranged at the center of the interval between the channel steels 2, 2, and the other flange 5 is arranged at right angles to the center of the web of the channel steels 2, 2.
protrudes through the web of the channel steel 2.

Alternatively, as shown in FIGS. 4 and 5, the tip of the flange 5 can be butt welded to the inner surface of the web of the channel steel 2, and the plunger 5' can further protrude from the outer surface of the web.

Then, a beam steel frame 6 made of angle iron or the like is connected to each flange protruding from the column steel frame 1.

In the case of an SRC structure, reinforcing bars 7 are arranged between the intervals between the channel steels 2 and 2 and through the webs of the channel steels 2 and 2.

By the way, the joining plate can be changed in various ways.

As shown in FIG. 6, in order to lengthen the welding length of the channel steel 2 to the web, both ends of the flange 5 can be made to protrude 8 vertically.

Also, as shown in Figs. 7 and 8, reinforcing bar insertion holes 9 are provided in the flange 5.
can be provided.

As shown in FIGS. 9 to 12, when the flange 5 is inserted into the web of the channel steel 2, a reinforcing plate 11 is provided around the insertion hole 10.

In addition, the flange 4 of the joint plate 3 arranged at the center of the interval between the channel steels 2 and 2 is a plate 12 that spans the flange of the channel steel 2 and the flange 4, or an angle plate, etc., as shown in FIGS. 13 and 14. connected by.

This invention has the above configuration, and since the channel steels are arranged at intervals, it is possible to attach joint plates, etc.
It is easy to arrange reinforcing bars when constructing an RC structure.

Also, when burying in concrete, it is best to surround it with concrete.

Furthermore, steel frames are relatively lightweight and can be made from common steel materials, making them easy to manufacture and process.
