The wedge pin having a wedge pin (35A) is introduced into the joint hole (45a) of the lower connecting portion 45 of the longitudinal connecting means 40, and the head (36a) caught inside the lower panel rim 13 ( It consists of a wedge pin (36A ') to fit in the slot (36b) exposed to the lower connection portion 45 outside the 35A).

Further, as shown in FIGS. 1, 2B, and 3B, the width of the smooth portion 31 of the lateral connecting end 30 is equal to the width of the lower panel 10, and the support member 39 is provided. The smooth portion) 31_ has a length that can protrude to both sides,

The lower connecting portion 45 of the longitudinal connecting means 40 can be supported by the support member 39 so that a lot of load is applied during curing of the concrete (lower panel 10-horizontal connecting means 30). Combination] it is possible to increase the reliability of the formwork assembly (A) according to the present invention by enabling the organic connection between the transverse connecting means 30 and the other member in which the load is concentrated.

The application process of the beam formwork assembly A of the present invention as described above will be described in detail with reference to the accompanying drawings.

First, as shown in FIGS. 3A and 3B, the support member 39 is fixed and assembled to the mounting portion 35 of the plurality of lateral connecting means 30, and then assembled to the ground or the work bench. Inverted so that the smooth portion 31 faces downward,

As shown in FIG. 2A, the lower panel 10 is also positioned so that the flat plate 11 faces downward.

The lower panel 10 and the transversely extending connecting means 30 coincide with the coupling hole 13a of the lower panel rim 13 and the fastening hole 33a of the transverse connecting means contacting part 33 and fastening means. Bind each other using the (34) and the wedge pin (34B).

Subsequently, two supporting plate 37B insertion pieces 37b are slidably coupled to the guide grooves 37A of the supporting portions 37 of the lateral connecting means 30, and at this time, the support plate 37B has a bolt and The separation prevention protrusion 37C fixed by the coupling of the nut is already fixed.

When the lower panel and the lateral connecting means are connected by the length of the designed beam, the lower panel 10-the lateral connecting means 30 are inverted by using a device such as a manpower or a crane.

This [lower panel 10-lateral coupling means 30 combination] is balanced by the separation prevention projections 37C of the two support plate 37B in contact with the ground or work table.

Next, as shown in Figures 2b and 2c, the upper panel 20 is coupled to the [lower panel 10-lateral coupling means 30 combination],

At this time, the nail 36B, which is a joint means, is embedded in the outer frame member 23 of the upper panel 20 through the through hole 41a of the upper connecting portion 41 so that the longitudinal connecting means 40 is fixed. It may be in the form.

Connection of the upper panel 20 and the upper panel is made by the longitudinal connecting means 40,

If necessary, a separate connecting means, for example, may be in the form of reinforced by the connecting means for connecting the slab (slab) of the upper layer to be located above the beam formwork panel and the upper panel 20.

In the longitudinal connecting means 40 used to couple the upper panel 20 and the lower panel 10 to the lateral connecting means 30, the intermediate connecting part 43 is the lower panel 10. In contact with the protruding portion 11a of the flat plate portion 11,

The lower connecting portion 45 is exposed through the joint hole 45a of the lower connecting portion 45, the wedge pin 36A fitted through the coupling hole 13a of the edge 13 of the lower panel 10 The other wedge pin 36A 'is introduced through the slot 36b.

As a result, the beam formwork assembly A of the present invention, which is composed of a combination of the lower panel 10, the upper panel 20, the lateral connecting means 30 and the longitudinal connecting means 40, which are in close contact with each other, is completed. .

Such a formwork assembly (A) is arranged between two pillars (P1) (P2), which are already cured and molded by lifting with equipment such as a tower crane,

The transverse connecting means 30 ′ (see FIG. 1) serving as a filler is positioned at the contact surfaces of the pillars P1 and P2 and the cooking body A.

After the fixed position is lifted by the equipment and floating in the air, as shown in Figure 1, the separation preventing projection 37C protruding to the lower portion of the support plate 37B of the lateral connecting means 30 is

The copper bar is erected to support the copper bar assembly A so as to be positioned in the hollow 51 opened in the center of the contact plate 53 of the copper bar 50.

In this case, the club 50 is preferably in the form of a height adjustable.

Furthermore, when using the beam formwork assembly (A) according to the present invention has the advantage that the use of the wire and yoke material is unnecessary as described above, in addition to

In the conventional beam formwork, wait until the beams on the lower floor are cured enough to have sufficient bearing capacity after curing of the lower beams due to the Jangjae and Yoke materials (e.g. more than 4 days after the concrete is placed). Since the form panel had to be dismantled and moved to be reused for the beams of other parts of the building (upstairs or other spaces on the same floor), the utilization efficiency of materials decreased and the construction cost increased accordingly.

When using the beam formwork assembly (A) according to the present invention, as shown in Figure 4,

Only after the curing of the beam (J) for a certain time (for example, about 1 to 3 days after the concrete is placed) after the lateral connecting means 30 and 30 'acting as a filler and the copper bar 50 supporting it Leaving the upper and lower panels 20 and 10 are dismantled and moved to another part of the building to be reused, so the material utilization efficiency is much superior.

In the above description, the assembling order of the formwork assembly A according to the present invention and the supporting process using the copper circle 50 may be variously modified by those skilled in the art, and the present invention is not limited to the specific assembling order described. .

As described above, the beam formwork assembly according to the present invention allows the lower panel and the lower panel which form part of the formwork to be connected through a separate transverse connecting means, and the connection of the lower panel and the upper panel is also a separate species. It can be made through the directional connecting means to improve the assembly convenience and work efficiency, and in particular, the lateral connecting means of the specific structure can be supported by the right bar without skipping the conventional long wire and yoke material, reducing the material cost and work The transverse connecting means can also serve as a supporting area of the longitudinal connecting means, and in particular, when dismantling, the upper and lower panels can be dismantled more quickly than before, and used for the construction of other parts of the building. It is excellent in material utilization efficiency.

In the above description of the present invention, the formwork assembly for beams having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention may be variously modified and changed by those skilled in the art, and such modifications and changes may be made by the present invention. It should be interpreted as being within the scope of protection.
