Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Application Field The present invention relates to a steel beam provided with anchor pieces for temporary braces used for rebuilding after the assembly of the steel beam is completed. be.

BACKGROUND TECHNOLOGY Conventionally, as shown in FIG. 3, when a steel beam 11 is assembled by being joined to a steel column 10 having a height of several stories, when rebuilding the building, wire ropes 12 are used as shown in the figure. They were working on straightening out the distortion.

Problems to be Solved by the Invention However, the above-mentioned conventional rebuilding process involves work up and down several floors, which not only makes the work complicated and lacks safety, but also requires a large amount of force and is difficult to correct. There were drawbacks such as:

By the way, the present inventors have developed a construction method for each floor using column-attached beams instead of the conventional construction method as described above, and as shown in FIG. The steel beams 1 are assembled by joining them in the direction between the beams.

Therefore, the column-attached beams 4 are for one floor, and since they are manufactured in a factory, there is almost no need for accuracy correction after construction, and the steel beams 1 can be assembled in the inter-beam direction as shown in Figure 1. Only a small amount of subsequent reconstruction will be required.
Moreover, since this rebuilding work is done for each floor, it not only does not require strong force, but also has the advantage that the work process is extremely short.

The inventors of the present invention have realized that strong force is not required for rebuilding as described above, and that the steel beams
The anchor piece for the temporary brace attached to the
The present invention was developed by focusing on the fact that a hanging hook can be used as a hanging piece during erection work, and the purpose is to make a brace anchor piece double as a hanging piece. In this way, it is possible to eliminate the trouble of installing and removing hanging pieces, reduce costs and shorten construction period, and provide a steel beam equipped with anchor pieces for braces that can be erected safely and quickly. be.

[Structure of the Invention] Means for Solving the Problems A steel beam provided with the brace anchor piece of the present invention is an anchor having a hole drilled therein for hooking a lower hook portion of a temporary brace for rebuilding. In addition to attaching the bead to the steel beam, the above-mentioned piece is placed at a position on the top surface of the beam such that the steel beam can be suspended in a horizontal state when the hanging hook is hooked into the hole and lifted during construction. It is characterized by:

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a steel beam in the inter-beam direction, and a piece 2 is attached to the upper surface of the steel beam. A hole is drilled in the piece 2, and the piece 2 is hung by hooking a hanging hook of a hanging wire 3 of a crane, etc., as shown by the imaginary line, and the piece 2 is hung horizontally as shown in the figure. It is set between the beams 4, 4 and joined with bolts, etc., and the hanging hook is removed from the hole in the piece 2. Note that the hanging piece 2 attached to the steel beam 1 is attached at a position where the center of gravity of the steel beam 1 is calculated so that it can be stably lifted in a horizontal state.

Once the erection work is completed as described above, the next step is to rebuild.

When rebuilding, as shown in FIG. The upper hook part 5b of the temporary brace 5 is hooked into the hole 7a of the anchor piece 7 attached to the steel column 6 of No. 4, and the upper hook part 5b of the temporary brace 5 is tensioned with the turnbuckle 8, and the distortion is corrected while checking the construction. Note that 10 is the top surface of the concrete floor.

[Effects of the Invention] As described above, the present invention allows the anchor piece of the temporary brace for rebuilding to be used as a hanging piece for a hanging hook during erection, so the hanging piece does not have to be specially attached or removed. This not only saves time and money, but also allows the erection work to be carried out safely and quickly since the piece is placed on the top of the beam so that the steel beam can be suspended horizontally during erection.
