Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-assembled construction method which is carried out before placing a slab concrete of a bearing wall reinforcing bar of SRC construction.

[0002]

2. Description of the Related Art Conventionally, since beam a and wall b on the upper floor are reinforced after the slab concrete is cast, a wall streak c is performed before the concrete is cast (see FIG. 2).
The reinforcement of the wall reinforcing bar d was performed.

[0003]

In the above-mentioned conventional method, the work is complicated because the wall streak is performed before the slab concrete is poured and the streak after the marking is corrected to the proper position for assembly. In addition, there is a danger that the streak sticks to the worker's body during the upper work, and the streak is disturbed by concrete placement.

Further, the heads of the stiffeners fluctuate and are not stable, correct bar arrangement is not possible, and it takes time for the wall reinforcing bar assembly process after placing concrete. Furthermore, the space and process for floor concrete staking out and reinforcing bar loading overlap and become confusing. The present invention has been proposed in view of the problems of the conventional construction method, the object of which is to prevent the occurrence of disorder in the bar arrangement, eliminate the overlap of the process, and prevent the danger during work. The point is to provide a pre-assembly method for wall reinforcement.

[0005]

In order to achieve the above object, according to the method of pre-assembling a load-bearing wall reinforcing bar according to the present invention, after erection of a steel column or a PC column and a steel beam, the web of the steel beam portion is constructed. The brackets are attached at appropriate intervals along the longitudinal direction of the beam, and the upper main bars of the beam section are arranged over the respective brackets, then the ribs are arranged at predetermined intervals on the same main bar, and then the After arranging the lower main bar and binding the ribs to the upper and lower main bars, suspend the wall vertical bar on the upper main bar of the beam through a hook, and lower the wall vertical bar to the beam section of the lower floor. The fixing length is inserted into the wall to arrange the horizontal wall of the wall to the vertical wall of the wall.

[0006]

According to the present invention, as described above, after the steel frame or the PC column and the steel beam are erected, the reinforcing bar supporting brackets are provided on the web of the steel beam at predetermined intervals along the longitudinal direction of the beam. Install, bridge the upper main bar of the beam over the brackets, place the ribs at predetermined positions on the main bar, hang it, and pass the lower main bar of the beam over the lower part of each rib. The ribs of the SRC beam above the load-bearing wall are easily assembled in advance by binding the ribs and the upper and lower main bars together.

Next, the vertical wall of the wall is suspended using a hook by utilizing the upper main bar of the beam rebar thus assembled, and the lower part of the vertical bar of the wall is inserted into the beam portion of the lower floor with a required fixing length. By simply arranging the wall and arranging the horizontal wall of the wall to the vertical wall of the same wall, it becomes possible to reinforce the wall reinforcing bar before placing concrete.

[0008]

The present invention will be described below with reference to the illustrated embodiments. F ₁ is a floor to which the method of assembling the beam and the reinforcing bar of the bearing wall of the present invention has been applied and the placing of concrete has been completed. According to the assembling method of the load-bearing wall rebar of the present invention, after the construction of the steel frame columns (including the PC columns) and the steel frame beams is completed, the bracket 2 is appropriately attached to the web 1 of the steel frame beam G in the longitudinal direction of the beam. Projected at intervals, the upper main reinforcement 3 of the beam is arranged on each bracket 2,
Next, the ribs 4 are suspended from the main ribs 3 at the predetermined intervals, and the lower main ribs 5 of the beam portion are arranged on the respective ribs 4 to assemble the upper beam rebars above the SRC bearing wall first.

Next, the vertical reinforcing bar 6 of the load bearing wall is suspended from the upper main reinforcing bar 3 via the hook 6a, and the lower end portion is fixed to the lower floor portion by a fixing length 6
Only b is inserted, the horizontal reinforcing bars 7 of the wall are arranged on the vertical reinforcing bars 6, and the wall reinforcing bars are assembled first. In this way, when the first assembly of the reinforcing bars is completed, concrete is poured to construct the bearing wall and slab.

[0010] As described above, according to the present invention, conventional as pillars, in addition to the previous group of reinforcing bars of the beam, reinforcement of the bearing wall is also intended to previously set at the same time, F ₂ is previously set by the present process Indicates the floor on which According to this method, after the placing of the concrete on the floor where the pre-assembly of the load-bearing wall reinforcing bars has been completed as in the conventional method is completed, the reinforcement bars of the next floor can be saved and the effort can be saved without arranging the anchoring bars of the next floor. It can be omitted and the work can be done ahead of the upper floor without being influenced by concrete pouring.

In the figure, 8 is slab reinforcement and 9 is concrete.

[0012]

According to the present invention, as described above, after erection of a reinforcing bar column or a PC column and a steel frame beam, brackets are projected from the web of the beam at predetermined intervals in the longitudinal direction of the beam to bear a load bearing wall. The upper reinforcement of the upper SRC beam is arranged, the ribs are suspended on the same reinforcement, and the lower reinforcement is arranged on the same reinforcement, and the beam reinforcement is assembled first, and the wall reinforcement is attached to the upper reinforcement of the reinforcement. The beam reinforcement and wall reinforcement can be assembled first by suspending them via hooks and inserting the lower part of them into the beam portion on the lower floor by fixing length, and by arranging the lateral wall reinforcement. By omitting the stagger, the process wrap is eliminated and the risk of work by the stagger is eliminated.

Further, wall reinforcement can be assembled before placing the floor concrete, and disorder of the reinforcement can be prevented, so that good quality reinforcement work can be performed.
