Description

Formwork structure {A FORMWORK STRUCTURE}

This disclosure relates to a formwork structure for constructing structures such as beams or slabs of a building.

In a conventional building construction site, the form construction process is carried out by forming a form using various materials, then placing structural rebar and pouring foundation concrete on top of it.

These conventional forms are made on site by cutting and processing plywood and square lumber according to drawings, and must be dismantled again after pouring and curing the concrete. During the dismantling process, most of the formwork was damaged and could not be reused, which became a double burden as it had to be disposed of as waste.

Accordingly, in recent years, non-dismantled permanent formwork has been used in which formwork and some reinforcing bars are manufactured in advance at a factory, constructed on site, and then used without dismantling after pouring concrete.

These permanent forms can be manufactured in advance at a factory, and there is no need to dismantle the forms for walls and slabs after curing the concrete, which not only improves work efficiency but also reduces construction time and labor costs, so their use is increasing.

This permanent form can be used to support the load of structures such as deck plates or slabs during the construction of beam buildings. In this case, the formwork supports the structure with a lower wall and side walls to form an internal space. During the process of pouring and curing concrete in the internal space, the lower wall and side walls of the form are not only subjected to significant pressure from the concrete, but also receive significant vertical load from the structure under construction. Accordingly, the lower wall and side walls of the formwork may bulge outward, which makes the structure of the building unstable and increases the risk of causing a safety accident.

The present disclosure has been made in response to the above-described background technology, and is intended to provide a formwork structure that can provide high stability.

The technical problems of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

A formwork structure for solving the above-described problems is disclosed. The formwork structure includes: a bottom plate; a plurality of side plates each of which has a lower end connected to one of both sides of the lower plate to form an internal space; at least one lower plate bead protruding from the lower plate into the internal space and extending along the longitudinal direction of the lower plate; and at least one side plate bead protruding from the side plate into the internal space and extending along the height direction of the side plate; may include.

Alternatively, the longitudinal direction of the lower plate in which the lower plate bead extends and the height direction of the side plate in which the side plate bead extends may be perpendicular to each other.

Alternatively, the formwork structure may include: a stirrup connecting body extending along the longitudinal direction of the formwork structure and fixing the stirrup to the side plate or bottom plate by connecting means; It may further include.

Alternatively, the stirrup connection body may include: a lower plate stirrup connection body installed in parallel with the lower plate bead.

Alternatively, the formwork structure may further include: a plurality of stirrup connection support members located at a distance from each other on the top of the lower plate and extending across at least two of the lower plate beads.

Alternatively, the stirrup connection body may include: a lower plate stirrup connection body installed obliquely with the longitudinal direction of the formwork structure across at least two of the lower plate beads.

Alternatively, the stirrup connector may include: a side plate stirrup connector installed to intersect the side plate bead.

Alternatively, the formwork structure may have: one end connected to one of the two side plates located opposite each other on both sides of the lower plate, and the other end connected to one of the two side plates located opposite each other on both sides of the lower plate. It may further include a lateral pressure prevention member connected to the other one of the plates.

Alternatively, the form structure may further include: a lateral pressure prevention member hanger installed on the side plate bead at an angle with the height direction of the side plate bead so that one end of the lateral pressure prevention member can hang over it.

The present disclosure can provide a formwork structure that can provide high stability.

The plurality of plates constituting the formwork are each subjected to significant pressure in the lateral and/or vertical directions while the concrete inside is cured. Additionally, when a structure such as a deck plate is placed on top of the side plates of the formwork, the side plates are subjected to significant pressure in the vertical direction. In this case, the plurality of plates of the formwork may have a problem of swelling in the outward direction.

The formwork structure according to some embodiments of the present disclosure includes a plurality of plates of the formwork through a lower plate bead installed on the lower plate and a side plate bead installed on the side plate in a direction suitable for supporting the pressure caused by the concrete curing inside the formwork. This can prevent the problem of them swelling outward. Additionally, the form structure according to some embodiments of the present disclosure can effectively prevent (or support) lateral pressure applied to the side plate of the lateral pressure prevention member. The formwork structure of the present disclosure has high structural stability and can prevent the plurality of plates of the form from swelling or spreading. Hereinafter, specific embodiments of the formwork structure will be described with reference to the attached drawings.

1 is a perspective view of a formwork structure according to some embodiments of the present disclosure. FIG. 2 is a cross-sectional view of the formwork structure shown in FIG. 1.

According to some embodiments of the present disclosure, as shown in FIG. 1, the formwork structure 1000 includes a lower plate 100, a plurality of side plates 200, a lower plate bead 300, a side plate bead 400, and a strut. It may include a rub connector (500, 500A, 500B), a stirrup connector support member 510, and a stirrup 600. The structure of the formwork 1000 described above is merely an example, and any one of the above-described configurations may be removed or an arbitrary configuration may be added.

The formwork structure 1000 may be a structure for constructing a building structure. For example, the form structure 1000 may form an internal space where concrete is poured by combining a plurality of plates made of a rigid material (eg, a metal material) to construct a beam structure. In some examples, the formwork structure 1000 may support a structure such as a deck plate disposed on top of the side plate 200. However, it is not limited to this, and the form structure 1000 may include various structures for constructing a building structure.

The lower plate 100 and the plurality of side plates 200 may be connected to each other to form an internal space where concrete is poured. For example, the lower ends of the plurality of side plates 200 may be connected to one of both sides of the lower plate 100 to form an internal space. For example, as shown in FIGS. 1 and 2, two side plates 200 may be arranged on both sides of the lower plate 100 to face each other. In this case, the form structure 1000 may have a U-shape with an open upper surface. However, the formwork structure 1000 is not limited to this and may have various forms.

In some examples, when a structure such as a deck plate is installed on the formwork structure 1000, the upper end of the plurality of side plates 200 may contact the lower surface of the structure such as the deck plate. In this case, the lower ends of the plurality of side plates 200 may be connected to the side of the lower plate 100. Accordingly, a structure such as a deck plate can be supported by a plurality of side plates 200.

According to some embodiments of the present disclosure, at least one lower plate bead 300 may protrude from the lower plate 100 into the internal space and extend along the longitudinal direction of the lower plate 100. According to some embodiments of the present disclosure, at least one side plate bead 400 may protrude from the side plate 200 into the internal space and extend along the height direction of the side plate 200.

Referring to FIG. 1, the lower plate bead 300 may extend along the longitudinal direction of the lower plate 100 to be suitable for supporting the pressure applied in the vertical direction to the lower plate 100 of the formwork structure 1000. Additionally, the side plate bead 400 may extend along the height direction of the side plate 200 to be suitable for supporting pressure applied to the side plate 200 of the form structure 1000 in the vertical and outward directions. In some examples, the longitudinal direction of the lower plate 100 to which the lower plate bead 300 extends and the side plate to which the side plate bead 400 extends to further support the pressure applied in the outer direction of the formwork structure 1000. The height directions of (200) may be perpendicular to each other.

Specifically, in the case of a conventional formwork, beads installed on the side plate and bottom plate were installed extending in the same direction. For example, when the beads installed on the lower plate are installed in a direction crossing both sides of the lower plate where the side plates are installed, the form cannot effectively support the pressure applied to the lower plate in the outward direction. In this case, the conventional form had the problem of high installation cost and installation difficulty by installing a separate structure at the bottom of the form to support the pressure applied to the lower plate. Additionally, when the beads installed on the side plate are installed in the longitudinal direction of the side plate, the form cannot effectively support the pressure applied to the side plate in the vertical and outward directions. The formwork structure 1000 of the present disclosure includes a lower plate bead 300 extending along the longitudinal direction of the lower plate 100 and a side surface of the formwork structure 1000 to be suitable for supporting pressure applied in the vertical direction of the formwork structure 1000. The problem of the formwork plates swelling outward is solved through the side plate bead 400 extending along the height direction of the side plate 200 to be suitable for supporting the pressure applied to the plate 200 in the vertical and outward directions. It can be prevented effectively.

In some examples, the lower plate bead 300 and the side plate bead 400 may have various shapes, such as a plate shape, an A shape, or a T shape. In some examples, in order to effectively prevent the formwork structure 1000 from swelling in the outward direction, the lower plate bead 300 and the side plate bead 400 have higher rigidity than the lower plate 100 and the side plate 200. It can be manufactured from materials. In some examples, the bottom plate bead 300 and the side plate bead 400 may function as a coupling structure that secures the stirrup 600 to the internal space of the formwork structure 1000.

Stirrup connector 500 may be used to install stirrup 600. The stirrup connector 500 can perform a function of providing a binding force to the stirrup in a state where the bead and the stirrup are not welded (connected with a steel wire, etc.). Additionally, when the thickness of the fire-resistant coating changes depending on the purpose of the building (long-standing building, etc.), the thickness of the stirrup connector 500 can be adjusted to suit this situation. In some examples, as shown in FIG. 1, the stirrup connector 500 is installed in the longitudinal direction of the formwork structure 1000 so that the stirrup 600 can be installed in a direction intersecting the longitudinal direction of the formwork structure 1000. It can be extended according to . In this case, the stirrup connector 500 can be used to secure the stirrup to the side plate or bottom plate by any connecting means. In some examples, connecting means for securing stirrup 600 to stirrup connector 500 may include wire rope. However, it is not limited to this, and the connection means may include various methods.

In some examples, as shown in FIG. 1, the stirrup connector 500 is installed side by side with the lower plate stirrup connector 500B installed in parallel with the lower plate bead 300 and the side plate bead 400. It may include a plate stirrup connector (500A).

The side plate stirrup connector 500A and the bottom plate stirrup connector 500B may be fixed in different ways. For example, the lower plate stirrup connection body 500B may be fixed to the lower plate 100 using the stirrup connection support member 510 located at a distance from the upper end of the lower plate 100. In some examples, as shown in FIGS. 1 and 2 , stirrup connection support member 510 may extend across at least two bottom plate beads 300 . In this case, the stirrup connection support member 510 may extend in a direction perpendicular to the longitudinal direction of the lower plate 100. There may be a plurality of stirrup connection support members 510. In this case, the plurality of stirrup connection support members 510 may be positioned spaced apart from each other along the longitudinal direction of the lower plate. In this case, the lower plate stirrup connector 500B may be installed spaced apart from the upper end of the lower plate 100 along the longitudinal direction of the lower plate by spanning a plurality of stirrup connector support members 510. Since the lower plate stirrup connection body 500B is located at a distance from the top of the lower plate 100, the stirrup 600 can be easily installed on the lower plate stirrup connection body 500B using a wire or the like. The side plate stirrup connector 500A may be installed on the side plate 200 by being fixed in a direction perpendicular to each of the plurality of side plate beads 400 by any connecting means. For example, the side plate stirrup connector 500A may be fixed across a plurality of side plate beads 400 through welding or the like. However, it is not limited to this, and the side plate stirrup connection body 500A and the bottom plate stirrup connection body 500B may be installed in various ways.

In some other examples, the stirrup connector 500 may include a lower plate stirrup connector 500B installed across at least two lower plate beads 300 at an angle to the longitudinal direction of the formwork structure. In detail, the lower plate stirrup connector 500B may be installed by crossing two or more lower plate beads 300 at an angle to the longitudinal direction of the formwork structure, instead of crossing the stirrup connector support member 510. . In this case, the lower plate stirrup connector 500B is not parallel to the lower plate bead 300, but can be installed without using the stirrup connector support member 510. However, it is not limited to this, and the lower plate stirrup connector 500B can be installed in various ways.

The stirrup 600 may be fixed to the inside of the formwork by being connected to the stirrup connector 500. As shown in FIG. 1, the stirrup 600 may have a U-shaped open shape. As another example, the stirrup 600 may have a closed shape of a square ring, but is not limited thereto. As described above, the stirrup 600 may be connected to the lower plate 100 and the side plate 200 through the stirrup connectors 500A and 500B. Alternatively, the stirrup 600 may be fixed on a plurality of beads using fastening means such as welding or mounts, hooks, cable ties, and bolts/screws. The stirrup 600 may perform the function of a structure forming a building structure. In addition, the stirrup 600 may perform the function of supporting the lateral pressure of the side plate 200 together with the side plate bead 400 by being connected to the side plate.

Figure 3 is a perspective view of a formwork structure including a lateral pressure prevention member according to some embodiments of the present disclosure. FIG. 4 is a cross-sectional view of the formwork structure shown in FIG. 3.

In some embodiments of the present disclosure, the formwork structure 1000 may further include a lateral pressure prevention member 700.

In some examples, one end of the lateral pressure prevention member 700 may be connected to one of two side plates 200 located opposite each other on both sides of the lower plate 100. Additionally, the other end of the lateral pressure prevention member 700 may be connected to the other one of the two side plates 200 located opposite each other on both sides of the lower plate 100. By fixing both ends of the lateral pressure prevention member 700 to the two side plates 200 located opposite each other, the lateral pressure prevention member 700 prevents the lateral pressure that causes the two side plates 200 facing each other to spread apart. It can perform its function. Accordingly, the structural stability of the formwork structure 1000 can be increased.

In some embodiments of the present disclosure, the form structure 1000 may include a lateral pressure prevention member hanger 710 for fixing the lateral pressure prevention member 700.

Specifically, as shown in FIG. 3, the lateral pressure prevention member 700 may be installed at an angle with the height direction of one or more side plate beads. In this case, the lateral pressure prevention member hanger 710 may be installed on the side plate bead 400 at an angle with the height direction of the side plate bead 400 so that one end of the lateral pressure prevention member 700 can hang over it. For example, one end of the lateral pressure prevention member 700 may be placed on a structure where the lateral pressure prevention member hanger 710 and the side plate bead 400 intersect in an inclined X shape. As shown in FIG. 4, two lateral pressure prevention member hooks 710 are provided so that the lateral pressure prevention member 700 can be hung on two side plates 200 facing each other on both sides of the lower plate 100. It can be installed on two side plates facing each other. However, it is not limited to this, and the lateral pressure prevention member 700 may be fixed using various methods.

In some embodiments of the present disclosure, the form structure 1000 may further include a side support portion (not shown) to effectively support the vertical load of the side plate 200. In some examples, the side support may have a shape extending vertically along the side plate. In this case, one end of the side support may be in contact with the bottom of a structure such as a deck plate located at the top of the side plate 200. Additionally, the other end of the side support may be in contact with the top of the lower plate 100. Through this shape, the vertical load applied to the side plate 200 can be effectively supported.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the scope of the disclosure.
