Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam-deck deck plate,

The present invention relates to a deck plate and a construction method using the same. More particularly, to a beam-strengthening deck plate and a construction method using the same.

The structure of the building is divided into a wooden structure, a brick structure, a cement block structure, a stone structure, a reinforced concrete structure, a steel structure, and a steel reinforced concrete structure depending on the material of the subject structure.

Among them, the reinforced concrete structure, the steel structure and the steel reinforced concrete structure are structures in which the weakness of the tensile stress of the concrete is complemented by the steel aggregate such as steel bars, steel plates, and steel pipes.

The reinforced concrete structure is constructed in such a way that a reinforced structure is installed and a form is installed on the outer side of the reinforced concrete structure to pour concrete into the formwork. The steel frame structure is formed by assembling an important skeleton portion with a steel member, It is installed by installing concrete. The steel reinforced concrete structure is constructed by mixing the reinforced concrete structure with the steel concrete structure.

Such a conventional steel reinforced concrete structure requires a lot of time and cost to install the formwork, and after the concrete is cured, it is necessary to remove the formwork again with much time and cost. Therefore, the construction period of the building is very long, There was a lot of trouble.

Furthermore, in the case of constructing a multi-layered building, conventionally, it has been forced to sequentially construct one layer at a time. In other words, after installing the lowest reinforced steel or steel structure and installing concrete, concrete is cured and then reinforced steel, steel structure and form are installed on the upper layer, concrete is laid and cured repeatedly, Respectively. Accordingly, the construction period of the building is doubled depending on the number of the floors, and thus, it takes a lot of time and cost to construct the multi-story building.

In order to solve such a problem, Korean Unexamined Patent Publication (Kokai) No. 10-2016-0034136 discloses a method of assembling a load supporting structure having a plurality of beams, Installing a load supporting structure constituting one or more upper layers by combining a plurality of beams on the uppermost load supporting structure; Installing at least one of a mesh-like structure (exo-keelitone) for forming a wall and a deck plate for forming a slab in the lowermost and upper-layer load supporting structures; And placing the concrete in the interior of the mesh-like structure (exo-squeegee) or on top of the deck plate.

According to this high-speed construction method, a multi-layer structure is formed by assembling / joining a horizontal structure composed of a vertical structure including a tensile structure including a beam and a deck plate, and a lightweight concrete is laid thereon, Thus, the construction time of the multi-storey building can be shortened and the construction cost can be reduced.

However, in such a high-speed construction method, a large load is applied to a horizontal member such as a deck plate in a concrete casting (injection) process of forming a slab. In order to solve such a problem, there has been a limit in the above patent to use lightweight concrete. Lightweight concrete is made by replacing aggregate of ordinary concrete with artificial lightweight aggregate to reduce its weight. Foamed synthetic resin such as expanded polystyrene is used as artificial lightweight aggregate.

Korean Patent Publication No. 10-2016-0034136 Korean Patent Laid-Open No. 10-2016-0034117 Korean Patent Publication No. 10-2016-0034143

1 to 3 are views for explaining a construction method according to an embodiment of the present invention. The construction method of the present invention will now be described with reference to the drawings.

First, a load supporting structure of a building is installed as shown in FIG. This load-bearing structure comprises a plurality of vertical beams (1) functioning as columns. The vertical beam 1 may be a truss, an H-beam, an I-beam, an L-beam, a tubular beam, or the like. And a horizontal beam 2 is provided between the vertical beams 1. As with the vertical beam 1, the horizontal beam 2 may be a variety of trusses, H-beams, I-beams, L-beams and tubular beams.

In the illustrated embodiment, four vertical beams 1 are provided. However, the present invention is not limited thereto. The vertical beams 1 may be additionally provided between the vertical beams 1 according to the size and requirements of the building. ) May be installed.

And the reinforcing beams 3 are installed between the uppermost and lowermost horizontal beams 2. Like the vertical beam 1, the reinforcing beam 2 may be a variety of trusses, H-beams, I-beams, L-beams and tubular beams.

Next, as shown in Fig. 2, the beam-strengthening deck plates 10 are installed in the load-supporting structure. The beam-strengthening deck plate 10 can be installed in the load-supporting structure by fixing the ends of the beam-strengthening deck plate 10 to the horizontal beams 2. [ As shown in FIG. 2, the beam-strengthening deck plate 10 may be placed on the horizontal beam 2 and fixed with a bolt or welded.

FIG. 4 is a perspective view showing a part of the beam-strengthening deck plate shown in FIG. 2. FIG.

2 and 4, the beam-strengthening deck plate 10 includes a plate 11, a longitudinal stiffener 12, a transverse stiffener 13 and a gasket 14. As shown in Fig. Since the beam-strengthening deck plate 10 is reinforced by the transverse stiffener 13 and the longitudinal stiffener 12, it can withstand the placement of heavy concrete with a specific gravity of 2.5.

The plate 11 is formed with a plurality of protrusions 15 formed in a longitudinal direction at regular intervals along the lateral direction. The plate 11 can be made of steel, plastic, glass fiber reinforced plastic or the like.

Through-holes through which the transverse stiffener 13 can be inserted are formed in the side walls forming the protrusion 15 of the plate 11. A gasket (14) is inserted in the through hole so as to prevent concrete from leaking from the joint between the plate (11) and the transverse stiffener (13).

The longitudinal stiffener 12 is disposed in a space surrounded by the wall surfaces of the protrusion 15. As the longitudinal stiffener 12, an H-beam, a truss, a pipe, or the like may be used.

The longitudinal stiffener 12 is formed with an opening through which the transverse stiffener 13 can be fitted.

As the transverse stiffener 13, an H-beam, a truss, a pipe, or the like can be used. The transverse stiffener 13 passes through the through hole of the plate 11 and the longitudinal stiffener 12 alternately through the opening.

The beam-strengthening deck plate 10 is formed by fixing the longitudinal stiffeners 12 to the horizontal beam 2 and then placing the plate 11 on the longitudinal stiffener 12 and using the bolts or the like, After the plate 11 is engaged, the transverse stiffeners 13 can be fitted into the load supporting structure.

In some cases, the pre-assembled beam-strengthening deck plate 10 may be fixed to the horizontal beam 2. The beam-strengthening deck plate 10 raises the plate 11 on the longitudinal stiffeners 12 disposed at positions corresponding to the respective projections 15 and the through holes of the plate 11 and the longitudinal stiffeners 12, And the transverse stiffener 13 is inserted so as to pass through the openings of the transverse stiffener 13.

Although two beam-strengthening deck plates 10 are shown in FIG. 2, more beam-strengthening deck plates 10 may be provided depending on the number of layers. Of the beam-strengthening deck plates 10 shown in Fig. 2, the lower beam-strengthening deck plate 10 is a two-layer floor, and the upper beam-strengthening deck plate 10 is a roof-top floor.

Next, as shown in Fig. 3, the transverse stiffener 13 of the beam-strengthening deck plate 10 is connected to another beam-strengthening deck plate 10 immediately above via the up-and-down connecting stiffener 18. [ The upper and lower connecting stiffeners 18 may be connected to the transverse stiffener 13 of the beam-strengthening deck plate 10 in the upper layer. It is preferable to connect the upper and lower connecting stiffeners 18 so that the upper and lower connecting stiffeners 18 are vertically shifted by moving the position of the beam-strengthening deck plate 10 in the upper layer as much as the width of the projections 15. It may also be connected to the longitudinal stiffener 12.

The upper and lower connecting stiffeners 18 may be disposed at wall positions provided to divide the inner space of the layers (two layers in Fig. 2) between a pair of beam-strengthening deck plates 10 connected to each other. Therefore, after the building is completed, the upper and lower connecting stiffeners 18 are located inside the wall, so they are not visible from the outside.

The upper beam-strengthening deck plate 10 is connected to the uppermost reinforcing beam 3 via the upper and lower connecting stiffeners 18. And the lower beam-strengthening deck plate 10 is connected to the lowermost reinforcing beam 3 through the upper and lower connecting stiffeners 18. As a result, the upper and lower beam-strengthening deck plates 10 are structured to be supported up and down by the uppermost and lowermost reinforcing beams 3.

As the upper and lower connecting stiffeners 18, H beams, trusses, pipes, wires and the like can be used.

Next, a mesh-like structure (exoskeleton, not shown) is installed between the vertical beams 1 as load supporting structures. Such a mesh structure (exo-squeegee) is in the form of a net-like structure wall having a predetermined thickness. If necessary, exterior and interior materials may be attached to the interior and exterior surfaces of the mesh-like structure, respectively.

In this state, the concrete is supplied to the upper part of the beam-strengthening deck plate 10. The concrete then flows down along the beam-strengthening deck plate 10 and descends along the mesh-like structure between the vertical beams 1. Therefore, slab and wall concrete can be poured at once. High-rise buildings can be divided into 5 floors and laid at once.

When concrete is laid in this manner, most of the concrete placed in the mesh-like structure (exo-squeegee) forms a wall of the building together with the mesh-like structure (exo-squeegee) The reinforced concrete deck plate 10 forms a ceiling (slab) with the floor of the building.

In addition, a window frame or a door frame may be installed in advance in a mesh-like structure (exo-squeegee) to reduce the construction time and improve the convenience of installation.

5 is a view for explaining another construction method according to an embodiment of the present invention. This embodiment uses a method different from that shown in Fig. 3 in the step of reinforcing the beam-strengthening deck plate 10 after the steps shown in Figs. 5, the transverse stiffeners 13 are connected to the vertical beams 1 (see FIG. 1) positioned on the upper part of the beam-strengthening deck plate 10 by using the upper and lower connecting stiffeners 19 such as steel wires or pipes. ). These steel wires or pipes are removed from the steel wire or pipe exposed to the outside after the concrete has hardened.

6 and 7 are perspective views showing a part of a beam-strengthening deck plate according to another embodiment of the present invention.

The beam-strengthening deck plate 20 shown in Fig. 6, unlike the embodiment shown in Fig. 4, has only transverse stiffeners 23, and the beam-strengthening deck plate 30 shown in Fig. (32). When the area of the building is not large, a beam reinforcing deck plate having only one directional stiffener may be used, as shown in FIG. 6 or 7.

8 is a perspective view showing a part of a beam-strengthening deck plate according to another embodiment of the present invention. In the embodiment shown in FIG. 8, connectors 46 are formed on the upper surfaces of the protrusions 45 of the plate 41, unlike the embodiment shown in FIG. Thus, longitudinal stiffener 42 is exposed upwardly through connector 46.

1 to 3, the transverse stiffeners 13 are connected by the upper and lower connecting stiffeners 18 or the lower transverse stiffener 13 is connected to the upper longitudinal stiffeners 12. However, The beam stiffening deck plate 40 of the embodiment allows the longitudinal stiffener 42 of the lower beam stiffening deck plate 40 and the longitudinal stiffener 42 of the upper beam stiffening deck plate 40 The upper and lower connecting stiffeners can be connected to each other.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.

For example, the reinforcing beams 3 are provided at the uppermost and lowermost portions, but beam-reinforcing deck plates may also be provided.
