Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a metal fitting for connecting a reinforcing bar and a steel beam.

[0002]

[Prior art]

 Heretofore, a technology for assembling a reinforcing bar and a steel beam that directly connects the reinforcing bar and the steel beam has not been disclosed.

[0003]

[Problems to be solved by the device]

 As mentioned above, since the technology for directly connecting the reinforcing bar and the steel beam has not been established, there is a problem that the work of assembling the reinforcing bar and the steel beam on the site is increased and the number of construction days is increased.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned conventional problems, and the first gist of the present invention is to provide an inverted U-shaped portion which is fitted to a reinforcing bar to fix the reinforcing bar, and the inverted U-shaped portion. This is a joint metal member of a reinforcing bar and a steel beam, in which each end of the character-shaped portion is bent at a right angle in the longitudinal direction of the reinforcing bar, and the right-angled bent portion is fixed to the lower surface of the upper flange of the steel beam.

A second gist of the present invention is that a metal short tube portion to be inserted into a reinforcing bar and an outer periphery of the metal short tube section are integrated along the longitudinal direction of the reinforcing bar, and an upper flange of a steel beam is provided. It is a metal fitting of a reinforcing bar and a steel beam, which is composed of an L-shaped engaging portion fixed to the lower surface.

[0006]

[Action]

 According to the combined hardware of the first aspect of the present invention, the inverted U-shaped portion of the combined metal is fitted to the reinforcing bar placed on the upper surface of the upper flange of the steel beam, and the right-angled folding is performed in the combined metal. By fixing the curved part to the lower surface of the upper flange of the steel beam, the reinforcing bar and the steel beam can be integrated, and therefore, by assembling the reinforcing bar and the steel beam for each block in advance at the factory, It is possible to reduce the assembling work and reduce the number of construction days.

Further, according to the second aspect of the present invention, the metal short tube portion of the metal joint is inserted into the reinforcing bar placed on the upper surface of the upper flange of the steel beam, and the metal joint is attached. By fixing the L-shaped engaging part of the object to the lower surface of the upper flange of the steel beam, the reinforcing bar and the steel beam can be integrated, and therefore the reinforcing bar and the steel beam are preassembled in blocks at the factory. This will save on-site assembly work and reduce the number of construction days.

Then, as shown in FIG. 2, the inverted U-shaped portion 1 a of the combined metal fitting 1 is fitted to the reinforcing bar 3 mounted on the upper surface of the upper flange 2 a of the steel beam 2 and the straight part of the combined metal fitting 1 is fitted. The angled bent portion 1b is welded to the lower surface of the upper flange 2a of the steel beam 2 so that the reinforcing bar 3 and the steel beam 2 are integrated.

FIG. 3 is a perspective view of a metal fitting 11 according to a second embodiment of the present invention. The metal fitting 11 includes a metal short tube portion 11a to be inserted into a reinforcing bar and a metal short tube portion 11a. The L-shaped engaging portion 11b is welded to the outer periphery along the longitudinal direction of the reinforcing bar and fixed to the lower surface of the upper flange of the steel beam.

Then, as shown in FIG. 4, the metal short pipe portion 11 a of the joint metal fitting 11 is inserted into the reinforcing bar 3 mounted on the upper surface of the upper flange 2 a of the steel beam 2, and the L-shaped part of the joint metal fitting 11 is inserted. The bottom plate of the plate-shaped engaging portion 11b is welded to the lower surface of the upper flange 2a of the steel beam 2 to integrate the reinforcing bar 3 and the steel beam 2 with each other.

FIG. 5 is a perspective view of a metal fitting 21 according to a third embodiment of the present invention. The metal fitting 21 is placed on the upper surface of the upper flange 2a of the steel beam 2 as shown in FIG. The metal short pipe part 21a to be inserted into the rebar 3 is welded to the outer periphery of the metal short pipe part 21a along the longitudinal direction of the rebar 3 and fixed to the lower surface of the upper flange 2a of the steel beam 2. It comprises an engaging portion 21b and a fastening bolt 21c which is screwed to the bottom plate of the L-shaped engaging portion 21b and abuts against the lower surface of the upper flange 2a of the steel beam 2.

[0013]

[Effect of device]

 According to the above-described combined metal fitting of the present invention, the inverted U-shaped portion of the combined metal fitting is fitted to the reinforcing bar mounted on the upper surface of the upper flange of the steel beam, and the right angle of the combined metal fitting is fitted. By fixing the bent part to the lower surface of the upper flange of the steel beam, the reinforcing bar and the steel beam can be integrated. Therefore, by assembling the reinforcing bar and the steel beam for each block in advance at the factory, Assembling work at the site can be saved and the number of construction days can be reduced.

Further, according to the second embodiment of the present invention, the metal short tube portion of the second metal fitting is inserted into the reinforcing bar placed on the upper surface of the upper flange of the steel beam, and the second metal fitting is provided. By fixing the L-shaped engaging part to the lower surface of the upper flange of the steel beam, the reinforcing bar and the steel beam can be integrated, and therefore, the reinforcing bar and the steel beam must be preassembled for each block in the factory. As a result, on-site assembly work can be saved and the number of construction days can be reduced.
