As shown,

The improved yoke truss unit of the present invention includes two lattice roots 250 that are folded in a zigzag shape and have a narrow upper end and a wider lower end; An upper wire 230 joined to the top of the two lattice roots 250; And a lower wire (270) joined to the lower end of the lattice root (250) of the wire truss (200); And

An engaging plate 400 installed on the wall mold while pressing the lower wire 270 using the tie beam 300;

, ≪ / RTI >

The wire truss 200 is horizontally mounted on the outer surface of the wall mold,

And the coupling plate 400 is coupled to the tie beam 300 protruding from the outer surface of the wall mold while pressing the lower wire 270.

The tie beam 300 typically functions as a shear reinforcement, not as a function of maintaining the form spacing, but after the concrete is laid.

With two deck plates 100 facing each other,

And the improved yoke truss unit is installed on the outer surface of the deck plate 100.

At this time, the deck plate 100 may be of any type of de-molding or sloping type, but it is preferable that the deck plate 100 is composed of a sloping under-wall part buried in the ground,

11 is an example of the production of the wire truss of the present invention which is used in a slit form,

12 is an example of the production of a wire truss of the present invention used as a demolding.

As described above, the deck plate 100 can be used in any form of slope or demolding, but it is preferable that the underground outer wall portion buried in the ground is slanted and the underground inner wall portion is demolded.

At this time, when the deck plate 100 is formed in a sloped shape, the iron wire truss of FIG. 11 is used which does not deform the iron wire truss,

It is preferable that the wire truss of FIG. 12 is used so that the deck plate 100 can be demolded and the wire truss can be demolded.

The iron wire truss of the present invention used as the slant type of Fig. 11 has the same or similar shape as the iron wire truss of Fig. 2 (a)

Another embodiment of the wall formwork structure using the improved yoke truss unit of the present invention uses the improved yoke truss unit,

The wall mold is a deck plate 100 configured with an upper reinforcing bar 130, a lattice frame 150, a lower reinforcing bar 170 and a deck plate 110,

With two deck plates 100 facing each other,

The modified yoke truss unit is installed on the outer surface of the deck plate 100 constituting the inner wall of the two deck plates 100,

The claw portion 330 at the other end of the tie beam 300 is caught by the upper reinforcing bar 130 or the horizontal wall 700 of the wall of the deck plate 100 constituting the outer wall of the two deck plates 100 .

Here, the upper reinforcing bar 130 functions as a vertical reinforcing bar for the entire wall, and the horizontal reinforcing bar 700 serves as a horizontal reinforcing bar for the entire wall.

Figs. 7 and 8 show another embodiment of the wall formwork structure using the improved yoke truss unit of the present invention. In FIGS. 7 and 8, the wire truss 200 is omitted for convenience sake, but it will be understood that the wire truss 200 is actually provided.

The embodiment of Fig. 7 shows a state in which the center lines of the truss portions of the facing deck plates are aligned,

8 shows a state in which the center line of the truss portion of the facing deck plate is shifted, and Fig. 9 shows an advantage of the embodiment of Fig.

Generally, the deck plate 100 used in the present invention is preliminarily manufactured in a predetermined size.

Therefore, the embodiment of FIG. 7 is advantageous in that the spacing between both the molds is maintained without any additional means at the start and end positions of the inner wall and the outer wall form being the same, and is preferably used in the portion where the wall is not bent.

The embodiment of FIG. 8 is mainly used where the start and end positions of the inner wall and the outer wall form are different. Particularly, as shown in FIG. 9, there is an advantage that interference of the reinforcement is not generated near the corner of the wall.

In the embodiments of FIGS. 7 and 8, it is desirable to deploy the central horizontal reinforcement 800 at the center of the wall in practice.

Fig. 13 (a) shows an example in which truss members are used as a substitute for the central horizontal reinforcing bars in Figs. 7 and 8. Fig.

Fig. 13 to Fig. 13 (b) are front views of the truss member, and Fig. 13 (c) is a side view of the truss member.

As shown in the figure, the truss member is formed in a shape in which a reinforcing bar is joined to a truss reinforcing bar.

When using only the central horizontal reinforcing bar 800, the spacing between the deck plates 100 in Figures 7 and 8 is kept somewhat narrow. However, the truss members are spaced apart from each other by the interval between the deck plates 100 as shown in Figure 13 (a) It can be widely adjusted and it will be structured by horizontal reinforcement of the wall in the future.

In the present invention, a construction method for constructing the embodiment of FIGS. 7 and 8 will be described as follows.

(1) a decking step of erecting a plurality of the deck plates 100 in series on the ground so that the upper reinforcing bars 130, the lattice muscles 150 and the lower reinforcing bars 170 face upward;

(2) a deck unit forming step of binding the plurality of deck plates 100 to one deck unit by binding or joining the central horizontal reinforcing bars 800 to the upper reinforcing bars 130;

(3) a step in which the deck unit is poured into the deck unit by hooking a pair of hooks on the central horizontal reinforcing bars 800;

(4) a deck unit mounting step of vertically mounting the deck unit on the ground;

(5) Reinforcing the wall to reinforce the remaining wall reinforcement;

(6) a deck installation step of installing a plurality of deck plates 100 on the opposite side of the deck unit, one by one;

And a control unit.

The central horizontal reinforcing bar 800 functions as a support for hanging a pair of hooks at the time of buckling and the upper reinforcing bars 130 of the deck plate 100 are brought into contact with the deck unit after the walls are installed, Since it has a function to keep it open, there is an advantage that a separate interval adjustment is not necessary.
