Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of assembling a frame for a steel-reinforced concrete IJ-contact structure, in which the frame unit is formed by prefabricating.

(Problems to be Solved by the Invention) Prefabricating a frame unit in a steel reinforced concrete structure has conventionally been carried out by assembling columns and beam steel frames, followed by column reinforcement and beam reinforcement arrangement, but this method However, there is a problem in that it is difficult to arrange and position the stirrups.

This invention was made to solve the problems associated with assembling the frame unit, and attempts to solve this problem by assembling the reinforcing bars in advance.

(Means for Solving the Problems) In the present invention, after the column reinforcement is assembled into the ground prior to the column steel frame position, the steel frame unit formed by assembling the column steel frame and the beam steel frame is suspended over the column reinforcement, and the column reinforcement is By inserting the steel frame into the column reinforcement, it is possible to easily arrange reinforcement to the O-column steel frame, and at the same time, to ensure its positioning.

The main reinforcement bars and tie bars of the column bars are assembled in a subassembly yard at intervals equivalent to the span of the steel frame unit, the steel unit is suspended there, and the column steel frame is placed in the center of the tie bars.

Furthermore, main beam reinforcement and stirrups are arranged around the beam steel frame to form a steel-frame reinforced concrete frame unit.

(Example) The present invention will be explained below based on the drawings showing one embodiment.

In this invention, after the column main reinforcement 1a and the tie reinforcement 1b are assembled into the ground,
This is a method of prefabricating the frames and assembly unit B that constitutes the steel reinforced concrete frame by inserting the column steel frame 1 of 22) A, which is assembled by joining the beam steel frame 2 to the column steel frame 1.

The beam steel frame 2 is joined to the central part of the column steel frame 1, and the frame unit A is assembled into an H shape as shown in FIG.

Next, an example of the construction procedure will be explained according to FIG.

First, the main column reinforcements 1a and stirrups 1b are assembled into the ground at intervals equivalent to the span of steel frame unit A (I).

Next, suspend the steel frame unit) A from above (■),
Place the column steel frame 1 at the center of the stirrup 1b (II[)
.

Next, the main beam reinforcement 2a is arranged around the beam steel frame 2 and after pressure welding (■
), the stirrup 2b is reinforced V).

Work on converting the framework unit to Robreno has been completed i)
.

Note that the beam main reinforcements 2a and stirrups 2b may be placed in place at the time of assembling the steel frame unit A.

Figure 2 shows the on-site construction method using this frame 22)B.

This construction procedure will be explained.

First, erect the frame 22) B in the designated position (1).

The column steel frame 1 and the column steel frame 1 protruding from the upper surface of the slab are connected, and the column main reinforcements 1a and 1a are connected to each other (■).
, the beam steel frames 2 and 2 are joined, and the beam main reinforcements 2a l 2a are connected (1).

Next, pillar steel frame 1,1. Attach the stirrups 1b and stirrups 2b to the joints of the beam steel frames 2 and 2, respectively, and construct the frame 22)
The assembly work at site B is completed.

(Effects of the Invention) This invention is as described above, and since the column steel is inserted after the column reinforcement is assembled first, the reinforcement arrangement and positioning of the tie bars is facilitated, and the workability of prefabricating the frame unit is improved. Improved.
