Description

Formwork structure for supporting deck plates {A FORMWORK STRUCTURE FOR SUPPORTING DECK PLATES}

The present disclosure relates to constructing a structure such as a beam or slab of a building, and specifically to a formwork structure for supporting a lower portion of a deck plate.

In a conventional construction site, the formwork construction process is performed by forming a formwork using various materials, then placing structural reinforcing bars, and pouring foundation concrete thereon.

This conventional formwork is made by cutting and processing plywood and square materials according to drawings on site, and must be dismantled again after concrete is poured and cured. During the dismantling process, most of the formwork was damaged and could not be reused, so it became a double burden to be disposed of as waste.

Accordingly, in recent years, a non-dismantling permanent formwork that can be used without dismantling after prefabricating formwork and some reinforcing bars in a factory, constructing them on site, and then pouring concrete is used.

Such permanent formwork can be manufactured in advance in a factory, and there is no need to dismantle the formwork of walls and slabs after curing concrete, so work efficiency as well as shortening of the period and labor cost can be reduced, and its use is increasing.

This permanent formwork can be used to support the load of deck plates and slabs during the construction of beam structures. In this case, the formwork supports the deck plate through the side walls for forming the inner space. During the process of pouring and curing concrete in the interior space, the sidewall of the formwork not only receives considerable lateral pressure due to the load of the concrete, but also receives considerable vertical load due to the deck plate. Accordingly, the side walls of the formwork may swell outward, which destabilizes the structure of the building and increases the risk of causing safety accidents.

1 is a partial cross-sectional structural view of a formwork structure for supporting a deck plate according to some embodiments of the present disclosure.

Referring to FIG. 1 , a formwork structure 1000 for supporting a deck plate may be a structure for constructing a building structure. For example, the formwork structure 1000 for supporting the deck plate forms a space inside in which concrete is poured by combining a plurality of plates made of a rigid material (eg, metal material) to construct the beam structure 3000. can do. In this case, the formwork structure 1000 for supporting the lower deck plate may support the deck plate 2000 disposed on top of the side plate.

The side plates constituting the formwork for supporting the conventional deck plate are subjected to considerable pressure in the lateral direction while the concrete inside is cured. In addition, since the deck plate is disposed on top of the side plates of the formwork, the side plates are subjected to considerable pressure in the vertical direction. In this case, the side plates of the formwork may have a problem of swelling outward due to the vertical load of the deck plate and the lateral pressure generated by the concrete being cured inside the formwork.

The formwork structure 1000 for supporting a deck plate according to some embodiments of the present disclosure may include a side support for supporting a vertical load of the deck plate 2000 and a pressure caused by concrete curing inside the formwork. The side support may be located under the deck plate to support the load. In addition, the side support may be connected to the side plate through a bead protruding from the side plate to support the pressure applied on the side plate. Therefore, the formwork structure 1000 for supporting the deck plate of the present disclosure has high structural stability, and can prevent the side plates from swelling or spreading. Hereinafter, specific embodiments of the formwork structure 1000 for supporting a deck plate will be described with reference to the accompanying drawings.

The structure of the above-described formwork structure 1000 for supporting the deck plate is merely an example, and any one of the above-described structures may be removed or an arbitrary structure may be added.

The lower plate 100 and the plurality of side plates 200 may be connected to each other to form an internal space in which concrete is poured. For example, as shown in FIG. 2 , two side plates 200 on both sides of the lower plate 100 may be disposed to face each other. In this case, the formwork structure 1000 for supporting the deck plate may have a U-shape with an open upper surface.

The support connection part 500 may have various shapes. For example, the support connection part 500 may have a shape penetrating the upper and lower surfaces of the bead. Also, the support connection part 500 may be an opening having a shape corresponding to the side support part 400 . For example, when the side support part 400 has a bar shape, the support connecting part 500 may have a rectangular opening through which the bar shape of the side support part 400 can pass. As another example, when the side support part 400 has a cylindrical shape, the support connecting part 500 may have a rectangular opening through which the cylindrical shape of the side support part 400 can pass. However, it is not limited thereto, and the support connection part 500 may have various shapes. Here, the support connection part 500 has a shape corresponding to the side support part 400 when some space is left on the support connection part 500 by passing the side support part 400 on the support connection part 500 or not. If not, you can include all of them.

The support connection part 500 may connect the side support part 400 to the plurality of side plates 200 . Specifically, the side support portion 400 may be installed so that one end thereof is in contact with the lower surface by passing through the support connecting portion 500 of the first bead connected to the plurality of side plates 200 . In this case, the lateral pressure applied to the plurality of side plates 200 may be transmitted to the side support 400 through the support connecting portion 500 . Therefore, the side support part 400 can perform a function of increasing the overall strength of the formwork structure 1000 for supporting the deck plate by reducing the lateral pressure applied to the plurality of side plates 200 .

According to some embodiments of the present disclosure, the uppermost bead 310 of the first beads 310, 320, and 330 may be disposed between the side support 400 and the deck plate 2000 when the deck plate 2000 is installed. can In other words, the lower surface of the deck plate may be in contact with the upper surface of the uppermost bead 310 and the lower surface of the uppermost bead 310 may be connected to the upper end of the side support 400 . In this case, the side support part 400 may vertically support the plurality of side plates 200 by supporting the uppermost bead 310 upward. Accordingly, resistance to pressure in the vertical and lateral directions of the plurality of side plates 200 may be increased, and thus the overall strength of the formwork structure 1000 for supporting the deck plate may be increased.

According to some embodiments of the present disclosure, the stirrup 600 may be connected to a plurality of beads and fixed to the inside of the mold. The stirrup 600 may be fixed on a plurality of beads using fastening means such as welding or mounting, hooks, cable ties, bolts/screws, or the like.

In this case, as shown in FIG. 3A , the support connection part 500 may have a 'c' shape. When the area corresponding to all or most (eg, 90% or more) of the side surface of the side support 400 is directly connected to the side plate 200, the lateral pressure applied to the side plate 200 is An area transferred onto the support part 400 may be widened. Accordingly, resistance to lateral pressure of the side plate 200 may be increased.

As another example, referring to FIG. 3B , the side support part 400 may be connected to the side plate 200 only through the support connecting part 500 . In this case, as shown in FIG. 3B , the support connection part 500 may have a 'ㅁ' shape. In addition, the side support 400 may be made of a material or structure capable of withstanding a higher vertical load than the side plate 200 . Accordingly, a vertical load applied by the deck plate 2000 may be applied mainly to the side support. Therefore, a phenomenon that the side plate 200 swells outward due to pressure in the vertical direction can be prevented.

4 is a perspective view showing a modified configuration of a formwork structure for supporting a deck plate according to some embodiments of the present disclosure.

In some embodiments of the present disclosure, the formwork structure 1000 for supporting the deck plate may further include a deck supporting part 700 .
