DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pre-assembly method for beam reinforcing bars and an apparatus therefor.

(Prior art) Figures 5 to 7 show beam reinforcing bars (D), and upper main reinforcements (a).
) and the lower end main reinforcement (b1), the ribs (S) are arranged between them.

Conventionally, when pre-assembling the beam reinforcing bars, the beam main reinforcement is arranged, and if the cost reinforcement (S) is of the closed type as shown in Fig. 11, it is inserted from the main reinforcement end, and as shown in Fig. 12. In the case of the open type, the ribs were bent as shown by the dotted lines, inserted into the main reinforcement from the side, and then welded.

(8 Problems to be Solved by the Invention) However, when inserting closed type ribs as main reinforcing bars, if the main reinforcing bars are previously received by horizontal supporting members, the reinforcing bars may get in the way and become impossible to insert.

On the other hand, the open ribs were inserted laterally into the main reinforcement and then welded on site, which required a great deal of effort and time.

The present invention has been proposed in view of the problems of the prior art, and its purpose is to provide an improved method and apparatus for assembling beam reinforcing bars that can easily and quickly assemble beam reinforcing bars in advance. It is in the point of providing.

(Means for Solving the Problems) In order to achieve the above object, the method for assembling beam reinforcing bars of the present invention includes a hairpin in which vertical mounting holes are arranged in rows at predetermined intervals between the tops of both side supports of a fixed frame. A pipe is hung horizontally, and then the vertical leg piece of a T-shaped rib temporary support member consisting of a top horizontal piece and a vertical leg piece is placed vertically so that the horizontal piece is perpendicular to the hairpin pipe. Suspending the required number of ribs on the horizontal piece by fitting into the mounting holes, then inserting the upper end main reinforcement of the beam into each of the ribs, and placing it at a predetermined position on the hairpin pipe, Next, the ribs are removed from the top horizontal piece of the rib temporary support member, suspended and tied at a predetermined position on the upper end main reinforcement of the beam, and the lower end main reinforcement of the beam is inserted through the rib and tied. has been done.

Furthermore, in order to efficiently perform the method for assembling beam reinforcing bars, the beam reinforcing bar assembling apparatus of the present invention includes a fixed pedestal having a pair of opposing supporting columns on both sides, and a horizontally removable horizontal structure between the tops of the supporting columns on both sides of the fixed pedestal. A hairpin pipe for supporting the main reinforcing bars at the upper end of a beam with vertical mounting holes drilled at predetermined intervals, as well as a vertical leg piece that is inserted into the vertical mounting hole of the hairpin pipe, and a horizontal top part for hanging the ribs. It consists of a T-shaped rib temporary support member made up of two pieces.

(Function) The present invention involves fitting vertical leg pieces of a T-shaped rib temporary support member into vertical mounting holes provided in a hairpin pipe horizontally suspended on both side supports of a fixed frame, and connecting the hairpin pipes in the same member with each other. A required number of ribs are inserted into the top horizontal pieces intersecting at right angles and suspended to temporarily support the ribs.

In this state, the upper end main reinforcement of the beam is inserted through the ribs, and the reinforcements are mounted at a predetermined position on the hairpin pipe, and then the ribs are removed from the horizontal part of the rib holding member and the beam is inserted into the ribs. Move it onto the upper main reinforcement, and suspend and tie it at a predetermined position on the upper main reinforcement.

Next, the main reinforcement at the lower end of the beam is inserted through each of the ribs and attached to a predetermined position, and after the beam reinforcing bars are assembled, the beam reinforcing bars are lifted and the hairpin pipe is removed from the fixed frame.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Vertical locking pieces (4) are welded to the top of the hairpin pipe (B), and both ends of the hairpin pipe (B) are fitted across the vertical locking pieces (4) (see Figure 8). Insert the vertical leg piece (5) of the rib temporary support member (C) into the required vertical mounting hole (3) of B) so that the top horizontal piece (6) extends perpendicularly to the hairpin pipe (B). (7) in Figure 0 to be inserted is the vertical leg piece (5

Next, the top horizontal piece (6) of the rib temporary support member (C)
Suspend the required number of ribs (S). (Refer to Figure 3) In this way, the ribs temporarily supported by the rib temporary support member (C) (
The upper end main reinforcement (a) of the beam is inserted into the beam S), and the upper end main reinforcement (a) is mounted at a predetermined position on the hairpin pipe (B). In the figure, (4a) is a guide roller installed between the brackets (4b) of the vertical locking pieces (4) of both branches (2), which improves the sliding of the upper main reinforcement (a) of the beam. . (See Figures 9 and 10) On the other hand, horizontally connect the left and right branches (2) of the fixed frame (A) with pins (8) inserted through pin holes arranged in the vertical direction. The lower end main reinforcing bars (b) of the beams inserted through the cost reinforcements (S) are mounted at predetermined positions on the supported lower end main reinforcing pipe (9).

Next, the cost reinforcement (S) is removed from the top horizontal piece (6) of the cost reinforcement temporary support member (C), placed at a predetermined position on the upper end main reinforcement (al), and tied to the upper end main reinforcement (a). Suspended from the rib (a), the rib temporary support member (C) is suspended from the pipe (

).

(Effects of the Invention) According to the beam reinforcing bar assembly method of the present invention, as described above, the T-shaped ribs are fitted into the vertical mounting holes of the hairpin pipes, which are removably suspended horizontally between the tops of the columns on both sides of the fixed frame. The ribs, which are suspended and temporarily supported by the top horizontal piece of the reinforcement holding member perpendicular to the hairpin pipe, are placed at a predetermined position on the hairpin pipe. The beam was moved to a predetermined position on the upper main reinforcing bar and tied together, and then the lower end main reinforcing bar of the beam was attached to the cost bar suspended from the upper end main reinforcing bar, and the beam reinforcing bars were assembled in advance. Closed type reinforcing bars can be attached to the beam main reinforcement as they are without any trouble, and unlike the case where open type reinforcing bars are used, on-site welding work is not required, and reinforcing bar assembly work can be easily and quickly performed.

Furthermore, the beam reinforcing bar assembly device according to the present invention serves as a fixed pedestal for assembling beam reinforcing bars, as well as for attaching a cost reinforcement temporary support member and setting the upper end main reinforcement of the beam, and can be freely attached and detached between the columns on both sides of the fixed pedestal. A hairpin pipe suspended horizontally on the hairpin pipe, and a rib temporary support member that is removably inserted into the vertical mounting hole of the hairpin pipe and temporarily supports the ribs until they are attached to the beam upper end main reinforcement placed on the hairpin pipe. With this configuration, the method for assembling the beam reinforcing bars can be carried out efficiently.
