Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a pre-assembled column / beam unit reinforcing bar.

[0002]

2. Description of the Related Art When a super high-rise building is designed with a reinforced concrete structure, since the reinforcement of columns is dense, there has been a major obstacle in terms of quality and efficiency in the conventional reinforcement at the site.

[0003]

Therefore, in a super-high-rise building made of reinforced concrete, prefabricated reinforcing bars preassembled in a dedicated factory are generally used. However, assembling such super-sized pre-assembled reinforcing bars is required. The work is not easy, requires a large amount of labor and labor, and a large number of reinforcing bars interfere with each other, making it difficult to perform a rational work.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a highly accurate workability in which a super-large H-shaped column-beam unit reinforcing bar is rationally assembled. The point is to provide an excellent rebar assembly method.

[0005]

In order to achieve the above object, according to the method of assembling a pre-assembled column and a beam unit rebar according to the present invention, the left and right sides 1 in which a column rebar group is provided oppositely through a panel zone. A beam unit is horizontally placed on a slide frame at an intermediate position between a pair of half-divided column units and both half-divided column units, and the beam reinforcing bar fixing end of the beam unit is placed in the panel zone of each half-divided column unit. Insert the column rebar groups that face each other across the panel zone in the adjacent column half-division unit, and join the reinforced joints on the outer side and the inner core by lap joints outside the panel zone. When assembling the split unit, the pillar rebars of the split unit are assembled with a predetermined gap held therebetween via a template.

[0006]

As described above, according to the present invention, the column half-divided reinforcing bar unit oppositely arranged on the slide base is constituted by the group of opposing column reinforcing bars with the panel zone interposed therebetween. The beam reinforcing bar anchoring portion in the beam reinforcing bar unit disposed in the middle is inserted into the panel zone of the half columnar unit, and the column reinforcing bar groups facing each other through the panel zones of the respective half columnar units are provided in other than the panel zone. The outer side is a reinforcing bar, and the inner side is a core bar that is joined by a lap joint, and an H-shaped pre-assembled column beam unit rebar is assembled by a column rebar and a beam rebar.

At this time, a template is used for assembling the column rebar of the half-column unit to maintain the space between the rebars and increase the rigidity during suspension.

[0008]

The present invention will be described below with reference to the illustrated embodiments. 1 is a slide mount installed on the base, and a pair of opposing left and right half-divided column units A are horizontally placed. In the middle of the both half-divided column units A, a beam X reinforcing bar fixing end b is placed. The beam unit B which it has is mounted horizontally.

In the half-split pillar unit A, a pair of upper and lower pillar rebars 2 are provided opposite to each other via a panel zone a. 3 is a hoop muscle, and the hoop muscle 3 is not arranged in the panel zone a. Reference numeral 4 is a beam reinforcing bar, and 5 is an X-shaped beam reinforcing bar fixing portion. (See FIG. 1) The opposing half-split column units A, A are moved in the direction of the arrow in FIG. 2 along the slide base 1, and the fixing end portion b of the beam X-shaped beam bar arranged in the beam unit B is moved. Insert into the panel zone of each of the half-split column units A, A.

In each of the half-divided pillar units A, the cores in which the end portions are hooked to the upper half-pillar unit ribs A ₁ and the lower half-pillar pillar ribs A ₂ which are adjacent to each other except in the panel zone. The muscles 6 are arranged along the main pillar muscles 7 so that the ends of the muscles 6 project outward from the ends of the pillar unit muscles. Reference numeral 8 in the figure denotes a width stop bar. As described above, after inserting the both-end beam reinforcing bar fixing portion 5 of the beam unit B into the panel zone of the half-divided column unit A, the outside is the inside of the half-divided unit reinforcement A ₁ or A ₂ except the panel zone. The child muscle 6 is pushed into the half-divided unit muscle A ₂ or A ₁ on the opposite side, and the shear reinforcement muscle 9 is laid in the hook portion at the tip and joined to each other by the lap joint method. Join through the method. In the figure, 11 is an auxiliary muscle.

The template 1 is provided at the end of the column rebar group 2.
2 are arranged, each rebar of the column rebar group 2 is inserted into the through hole 12a of the template 12 to maintain the interval between the column rebar groups 2, and to maintain the rigidity of the rebar group at the time of suspension, and the preceding bar. Reinforcing bar 2'that interferes with the coupling is lifted in advance. Thus, after the half-split column unit A and the beam unit B are assembled into an H-shape, the hoop muscles are arranged in the panel zone by split hoop muscles or the like.

After that, the H-shaped column and the beam unit rebar are hung at a predetermined position through the hanging jig C and set. In the figure, 13 is a fixing nut, and 14 is a coupler with a hanging hook.

[0013]

As described above, according to the present invention, the pre-assembled rebar columns,
The beam can be easily assembled into the H-shaped column and the beam unit, and the unit can be easily suspended at a predetermined position and assembled. Further, the template can be used for assembling the pillar unit to accurately hold the gap between the pillar rebars, to maintain the rigidity during hanging, and also to be used for hoisting the interfering reinforcing bars.
