[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper structure of a beam in a steel reinforced concrete structure.

[0002]

2. Description of the Related Art Recently, even in the construction of steel-framed reinforced concrete, a deck plate has been used for a slab in order to save labor and the like for the construction. In this case, the connection between the beam portion constructed as a steel reinforced concrete structure and the deck plate is as shown in FIG. In this figure, reference numeral 1 denotes a beam portion constructed as a steel-framed reinforced concrete structure. It is established. Reference numeral 5 denotes a slab, and the slab 5 has a deck plate 6 as a mold, and concrete is cast thereon. Then, a web 8 is formed from the lower surface of the upper flange 7 of the steel beam 2.
Gusset plates 9, 9 welded over the side surfaces are provided so as to protrude to the side, and deck plate receiving angles 10, 10 are attached to the respective ends thereof.
The steel beam 2 supports the deck plate receiving angle 10, and the deck plate 6 is placed on the deck plate receiving angle 10 and connected by welding or the like. In addition, 11 shows the formwork of a beam part.

[0003]

However, in the above-mentioned steel beams, gusset plates are often welded and carried in a factory, and in this case, the following problems have occurred. That is, the overhanging gusset plate is easily damaged during transportation and must be repaired on site. In addition, the arrangement of beams, especially stirrups, was extremely difficult to perform, and spiral streaks could not be used.

In view of the above circumstances, the present invention has an object to prevent the gusset plate from protruding greatly and not to obstruct the arrangement of the beams, and the steel beam supports the receiving angle for the deck plate. An object of the present invention is to prevent a gusset plate from being damaged when a steel beam is transported, and to facilitate a reinforcing work.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is a beam part constructed by steel reinforced concrete construction, and the steel beam of the beam part has a receiving angle for a deck plate. At the end of the supporting beam, the deck plate receiving angle On the upper flange of the steel beam ,
Attach the gusset plate fixedly provided on the upper flange of the front Symbol steel beam, on the end side of the coupling means, across the beam direction
The above-mentioned problem is solved by making a reinforcing bar hung .

[0006]

In the present invention, before the connecting means is attached to the gusset plate, only the gusset plate is located on the upper flange of the steel beam, and the gusset plate is for attaching the connecting means. , Will be small. Further, even if the steel beam is suspended and installed in this state, the gusset plate does not hinder the bar arrangement work. When the connecting means is attached, the receiving angle for the deck plate can be attached.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on one embodiment shown in FIG. In addition, the same reference numerals are given to portions having the same configuration as that of the conventional example shown in FIG. In the beam portion 1, a small gusset plate 1 is placed on the upper flange 7 of the steel beam 2. Thus, the connecting means is placed on the upper flange 7 and is mounted on the gusset plate 12 in the field. And this connecting means 13 is provided by assembling a plurality of angle members, the end portion side of the coupling means 13 it
As shown in the drawing, it has a shape that once descends downward from the upper flange 7 and then bends laterally.
The connection means 13 is attached to the gusset plate 12 after the steel beam 2 is erected and a predetermined reinforcing arrangement is performed. Linking
The part bent toward the side of the means 13 has a beam
Reinforcing bar 3 (two-stage bar in the illustrated example)
And the connecting means 13 supports the hung reinforcing bar 3.
I am trying to do it. And the end 1 of this connecting means 13
The deck plate receiving angle 10 is attached to 3a, and the steel beam 2 supports the deck plate receiving angle 10 via the connecting means 13 and supports the deck plate 6.

[0008]

[Effects of the Invention] As described above, according to the present invention,
It is a beam part constructed by steel reinforced concrete construction,
In the beam portion in which the steel beam of the beam portion supports the deck plate receiving angle, the deck plate receiving angle is attached to an end portion. Placed placed on the upper flange, Installing the coupling means, the gusset plate fixedly provided on the top flange of the front Symbol steel beam
A reinforcing bar extending in the beam direction is hung on the end side of the connecting means.
Since the steel beam is erected without connecting means, the gusset plate does not become a hindrance as in the past, simplifying the work of arranging beams. And ready-made products such as spiral stirrups can be used. Then, the gusset plate provided on the upper flange of the steel beam can be made small, and damage during transportation can be reduced. In addition, the arrangement (welding) of the gusset plate is simple, and the effect is excellent in practicality.
