Description

[Detailed description of the invention] The present invention relates to a support device for beam reinforcing bars.

To construct beams and walls in a concrete building: 1) A beam pre-assembled with pre-assembled reinforcing bars is erected between the erected columns, and a wall reinforcement is placed between the beam and the already completed floor. After arranging the reinforcement, formwork is placed and concrete is poured in one piece.

Figure 1 shows a conventional beam reinforcing bar support device.
Reference numeral 1 indicates an already completed floor, 2 indicates a column, and 3 indicates a beam made of prefabricated reinforcing bars. Because of the length, the two bodies are joined together by welding to a joining plate 3a in the center, and reference numeral 4 is the floor l
This is a wall reinforcement placed between the beam material 3 and the beam material 3.

The beam material 3 made of assembled reinforcing bars is a long and heavy object.
In order to prevent it from bending under its own weight, it was suspended by a steel wire 5, such as a piano wire, stretched between the center of the beam 3 and the pillar 2.

However, according to the above method, (1) the stretched steel wire 5 is located in the upper area of the beam 3 which serves as the work floor, which poses a hindrance to the work.

■Difficulty and instability in obtaining sufficient support;■
If column 2 is a reinforcing bar, steel 1i! Reinforcement is required at the part where the anchor is taken.

There were other drawbacks.

Therefore, the object of the present invention is to provide a support device for beam reinforcing bars to improve the above-mentioned points of entry.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3 of the drawings.

FIG. 2 is a front view showing essential parts of the present invention, and FIG. 3 is a side view of the same.

As with the conventional construction method, columns (not shown) are erected on the completed floor 11 that has already been poured with concrete, and beams 13 made of prefabricated reinforcing bars are erected between the columns.

This beam material 13 is preassembled on the ground in one piece if the length between the columns is short, or two or more pieces if the length is long, and the ends are joined to the joint plate 13a by welding or the like. This is an assembled reinforcing bar. The upper end of a support member 15 made of channel steel is welded to the joint plate 13a of the beam 13, and is vertically disposed perpendicular to the beam. On the other hand, on the floor 11 is a joint plate 1 similar to the joint plate 13a joined to the beam material on the floor immediately below.
3b is anchored and its upper end protrudes, and the upper end of wall reinforcement 14b also protrudes.

Therefore, the supporting member 1 is vertically installed from the constructed beam 13.
The lower ends of the joint plates 13b and 5 are integrally joined by welding or the like to support the beam 13 and prevent the beam from deflecting. After that, as in the conventional construction method, the wall reinforcements 14a are tied to the wall reinforcements 14b and the beams 13, and formwork is provided on both sides of the wall reinforcements and the beams (not shown), and the concrete including the support materials 15 is concreted. An integral beam and wall is constructed by pouring.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist. For example, in the above embodiment, channel steel was used as the support member 15, but existing steel frame materials such as engineered shaped steel or other narrow shaped steel, round or Izo steel pipes, etc. can be used. In addition, the support member 15 can be joined by not only welding but also bolt fastening or other known joining means as appropriate, and the anchor for joining the lower end of the support member 15 is not limited to the joining plate 13b on the floor immediately below. . Furthermore, the configuration of the assembled reinforcing bars, which are the beam members 13, can be applied to any structure other than the truss structure shown in the drawings, as long as the shape of the joint plate 13a is partially changed.

As described above, the support device for beam reinforcing bars according to the present invention has an upper end connected to a beam member made of prefabricated reinforcing bars installed between the beams, and a lower end of the supporting member vertically installed along the wall reinforcement arrangement on an already completed floor. The reinforcing bars are supported by being connected to anchors protruding from the wall, and the supporting members are embedded in the wall concrete.

It is most desirable to use existing steel frame materials such as shaped steel and steel pipes as the support member. The effects of the present application with the above configuration are as follows: (1) Unlike the conventional configuration in which steel wire is stretched over a beam serving as a work floor, the supporting member does not pose an obstacle to the work.

■ The main load on the columns is reduced, and there is no need to reinforce column reinforcing bars.

■ Use □ shaped steel, steel pipes, etc. as supporting members and install beam reinforcing bars □ Strongly support: something can be done.

(2) Supporting members such as shaped steel and steel pipes already exist and can be provided at low cost.

- Since the supporting member is embedded within the wall by pouring concrete into the wall, it does not spoil the aesthetic appearance, and it can also be used as a type of structural member if necessary.

As described above, although the beam reinforcing bar support device of the present application has an extremely simple structure, it exhibits effects that can improve the drawbacks of the conventional type.
