Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing bar assembly method used in cast-in-place concrete construction.

Conventionally, this type of reinforcement method has been carried out by tightening individual reinforcing bars on-site, resulting in complicated on-site construction, long construction periods, and complicated process control. The disadvantage is that there is a lot of waste. The present invention has been made in view of these conventional drawbacks.
This enables on-site reinforcement work to be carried out in a simple and short period of time.

Hereinafter, the configuration of the present invention will be explained based on an illustrated embodiment. FIG. 1 shows vertical bars (1) (1) of deformed reinforcement bars,
.

Similarly, the horizontal bar of deformed reinforcing bar (2) <2) , , and,
The welded wire mesh (3) is welded to each other in a mesh shape, and in this example, first, such a welded wire mesh (3) is made into a standard shape,
Various pre-assembled reinforcing bars as shown in FIGS. 2 to 6 are manufactured by modifying the welded wire mesh (3).

Now, to explain these, FIG. 2 shows a base reinforcement (4) constituting a peripheral part of the base reinforcement arrangement, and the welded wire mesh (3) is formed into a rectangular shape. On the other hand, Fig. 3 shows the corner base reinforcement (
5), the welded wire mesh (3) is also formed into a substantially rectangular shape, and in this embodiment, the base reinforcement (4) and corner base reinforcement (5), which have been previously assembled, form the base arrangement. I try to structure the muscles.

Next, FIG. 4 shows the wall reinforcement (6) and the welded wire mesh (3).
is formed into a rectangular shape with a predetermined width, and two
The reinforcing deformed reinforcing bars (7) are welded vertically. This reinforced deformed reinforcing bar (7) is designed to withstand shear force because the deformed reinforcing bars that constitute the longitudinal reinforcement (1) and the horizontal reinforcement (2) are designed to withstand shear force.
It is reinforced against bending.

Figure 5 shows a corner wall reinforcement (8), which is a welded wire mesh (3) which is rectangular with a predetermined width, similar to the wall reinforcement (6).
is bent at right angles, and two deformed reinforcing reinforcing bars (9) for bending reinforcement are vertically welded to the bent portion.

Finally, FIG. 6 shows the beam reinforcements (10) placed in the upper and lower parts of the opening, in which the weld metal (3) is processed into a rectangular shape with a predetermined width, and the horizontal reinforcements protrude from both upper and lower edges. (2) (2)
01. , two deformed reinforced reinforcing bars (,1,'
i) (11), and the ends of the transverse reinforcement (2) are welded to the irregular reinforcement reinforcement (11) (, '1.1) so that these two reinforcement reinforcement bars (11) (, '1.1) are parallel to each other in the horizontal direction. IIXI
A triangular bent portion (13) is formed so as to embrace I).

Next, to explain the reinforcement assembly method using each of the tapered reinforcing bars mentioned above, the corner base reinforcement (5) is
and base reinforcement (4) are laid at predetermined positions to perform base reinforcement. Next, on this base reinforcement arrangement, as shown in Figure 8, beam reinforcements (1
o) (1,0) ~ are placed so that the reinforcing reinforcing bars (11) are above and below, and similarly, the wall bars (6) are placed next to the beam bars (10).
) Corner wall reinforcements (8) are placed at each corner at predetermined positions on both sides. At that time, use the two reinforcing reinforcing bars (IIXIl,) above and below the beam bar (10) to connect the wall bar (6) or corner wall bar (8).
Reinforced reinforcing bars that intersect and cross each other (7)
Tie (11) together. Note that the beam reinforcement (10) has an opening (
13) Several types with different heights are prepared depending on the size of the device, and these are placed at respective positions.

The reinforcing reinforcing bars (11) of the beam bars (10) are bent in a U-shape at one end in the left and right direction, and furthermore, in the part directly connected to the □ corner, these reinforcing reinforcing bars (11) are bent at right angles. It is bent (12). A beam reinforcement (10) for the second floor is similarly connected to the upper part of the opening (13).

As described above, according to the present invention, it is only necessary to connect base reinforcements, corner base reinforcements, wall reinforcements, corner wall reinforcements, and beam reinforcements that have been preassembled in the form of welded wire mesh to each other on site. Compared to the conventional construction method in which individual reinforcing bars are connected one by one on site, the reinforcement work on site is much simpler, the work is easier, and the work can be completed in a shorter period of time. It can be manufactured in advance at a factory efficiently, and compared to cutting on site, it can minimize material waste, resulting in a lower overall cost.
