Description

Construction method using beam-reinforced deck plate}

The present invention relates to a construction method using a deck plate. In more detail, it relates to a construction method using a beam reinforcement deck plate.

The structure of the building is divided into wood structure, brick structure, cement block structure, stone structure, reinforced concrete structure, steel frame structure, and steel frame reinforced concrete structure, depending on the material of the main structure.

Among them, reinforced concrete structures, steel structures, and steel reinforced concrete structures are structures that compensate for the weakness of the tensile stress of concrete with steel aggregates such as reinforced bars, sections, steel plates, and steel pipes.

Reinforced concrete structures are constructed by installing a reinforced structure and installing a formwork outside it to pour concrete inside the formwork.In the steel structure, an important frame part is assembled with a steel member, and a steel member is used as a formwork or a separate formwork is used. It is installed and constructed by pouring concrete. Steel reinforced concrete structures are constructed in a way that a reinforced concrete structure and a steel concrete structure are mixed.

Such conventional steel reinforced concrete structures require 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 a great deal of time and cost, so the construction period of the building is very long and manpower and cost There was a problem with this taking a lot.

Moreover, in the case of constructing a multi-story building, conventionally, it was only necessary to construct one floor sequentially. In other words, a multi-storey building by installing reinforcing bars or steel structures at the lowest level, placing concrete by installing a formwork, and then curing the concrete, then installing reinforcing bars and steel structures and formwork on the upper layer again, and repeating concrete placement and curing. Was constructed. Accordingly, there is a problem that the construction period of the building is doubled according to the number of floors, and it takes a lot of time and cost to construct a multi-story building.

In order to improve this problem, Korean Patent Application Laid-Open No. 10-2016-0034136 includes the steps of installing a lowermost load-bearing structure by combining a plurality of beams; Installing a load supporting structure forming one or more upper layers by combining a plurality of beams on an upper portion of the lowermost load supporting structure; Installing at least one of a mesh-like structure (exo-skeleton) for forming a wall and a deck plate for forming a slab on the load-bearing structure of the lowermost layer and the upper layer; And pouring concrete into the mesh-like structure (exo-skeleton) or on the upper portion of the deck plate is disclosed.

According to this high-speed construction method, a vertical structure made of a tensile structure including a beam and a horizontal structure made of a deck plate are assembled/combined to form a multi-layered structure, and lightweight concrete is poured therein to simultaneously construct a plurality of layers. By doing so, there is an effect of shortening the construction period of a multi-storey building and reducing the cost required for construction.

However, in this high-speed construction method, a large load is placed on a horizontal member such as a deck plate in the concrete pouring (injection) process forming the slab. In order to solve this problem, the patent has a limitation that lightweight concrete must be used. Lightweight concrete is a weight reduction by replacing the aggregate of general concrete with an artificial lightweight aggregate. As the artificial lightweight aggregate, a foamed synthetic resin such as expanded polystyrene is used.

1 to 3 are views for explaining a construction method according to an embodiment of the present invention. Referring to this, the construction method of the present invention will be described as follows.

First, as shown in FIG. 1, a load supporting structure of a building is installed. This load-bearing structure comprises a plurality of vertical beams 1 serving 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 between the vertical beams (1), a horizontal beam (2) is installed. As with the vertical beam 1, the horizontal beam 2 may be variously used, such as a truss, an H-beam, an I-beam, an L-beam, and a tubular beam.

Meanwhile, in the illustrated embodiment, a structure in which four vertical beams 1 are installed is illustrated, but the structure is not limited thereto, and additional vertical beams 1 between the vertical beams 1 according to the width and requirements of the building ) Can also be installed.

And reinforcing beams 3 are installed between the uppermost and lowermost horizontal beams 2. Like the vertical beam 1, the reinforcing beam 2 may be variously used, such as a truss, an H-beam, an I-beam, an L-beam, and a tubular beam.

Next, as shown in FIG. 2, the beam reinforcement deck plates 10 are installed on the load supporting structure. The beam reinforcement deck plate 10 may be installed on the load-bearing structure by fixing the ends of the beam reinforcement deck plate 10 to the horizontal beams 2. As shown in FIG. 2, the beam reinforcement deck plate 10 is mounted on the horizontal beam 2 and then fixed with bolts or welding.

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

2 and 4, the beam reinforcement deck plate 10 includes a plate 11, a longitudinal reinforcement 12, a transverse reinforcement 13, and a gasket 14. Since the beam reinforcement deck plate 10 is reinforced by the transverse reinforcement 13 and the longitudinal reinforcement 12, it can withstand the pouring of heavy concrete with a specific gravity of 2.5.

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

The sidewalls forming the protrusion 15 of the plate 11 are formed with through-holes into which the transverse reinforcement 13 can be inserted. In this through hole, a gasket 14 is fitted so that concrete does not leak from the joint between the plate 11 and the transverse reinforcement 13.

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

In addition, the longitudinal reinforcing material 12 has an opening through which the transverse reinforcing material 13 can be fitted.

As the transverse reinforcement 13, an H-beam, a truss, or a pipe may be used. The transverse reinforcing member 13 passes through the through hole of the plate 11 and the longitudinal reinforcing member 12 alternately through the openings.

The beam reinforcement deck plate 10 is arranged with the plate 11 on the longitudinal reinforcement 12 after fixing the longitudinal reinforcement 12 to the horizontal beam 2, and the horizontal beam 2 and the horizontal beam 2 using bolts, etc. After the plate 11 is joined, it can be installed on the load-bearing structure by inserting the transverse reinforcing members 13.

In some cases, the pre-assembled beam reinforcement deck plate 10 may be fixed to the horizontal beam 2 and installed. The beam reinforcement deck plate 10 has a plate 11 on top of the longitudinal stiffeners 12 arranged at positions corresponding to each of the protrusions 15, and the through-holes of the plate 11 and the longitudinal stiffener 12 It can be assembled by inserting the transverse reinforcing material 13 so as to pass through the openings.

In FIG. 2, two beam reinforcement deck plates 10 are shown, but more beam reinforcement deck plates 10 may be installed depending on the number of floors. Among the beam reinforcement deck plates 10 shown in FIG. 2, the lower beam reinforcement deck plate 10 serves as a two-story floor, and the upper beam reinforcement deck plate 10 serves as a rooftop floor.

Next, as shown in FIG. 3, the transverse reinforcement 13 of the beam reinforcement deck plate 10 is connected to the other beam reinforcement deck plate 10 on the upper layer through the vertical connection reinforcement 18. The vertical connection stiffener 18 may be connected to the transverse stiffener 13 of the beam reinforcement deck plate 10 on the upper floor. Although it may be connected in a slightly oblique line, it is preferable to connect the upper and lower connecting stiffeners 18 to be vertical by moving the position of the beam reinforcement deck plate 10 on the upper floor about the width of the protrusion 15. It can also be connected to the longitudinal reinforcement 12.

The upper and lower connection stiffeners 18 may be disposed at a wall position installed to divide the inner space of the layer (the second floor in FIG. 2) between the pair of beam reinforcement 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 reinforcement deck plate 10 is connected to the uppermost reinforcing beam 3 through the upper and lower connection reinforcements 18. And the beam reinforcement deck plate 10 of the lower layer is connected to the reinforcing beam 3 of the lowermost part through the upper and lower connection stiffeners 18. As a result, the upper and lower beam reinforcement deck plates 10 are supported up and down by the upper and lower reinforcing beams 3.

H-beam, truss, pipe, wire, etc. may be used as the vertical connection stiffener 18.

Next, a mesh-like structure (exo-skeleton, not shown) is installed between the vertical beams 1 which are load-bearing structures. Such a mesh-like structure (exo-skeleton) forms a wall shape of a mesh-like structure having a predetermined thickness. If necessary, exterior and interior materials may be attached to the interior and exterior surfaces of the mesh structure, respectively.

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

When concrete is poured in this way, most of the concrete poured into the mesh-type structure (exo-skeleton) forms the wall of the building together with the mesh-type structure (exo-skeleton), and the beam reinforcement deck plate (10) The concrete poured into the floor and the ceiling (slab) of the building together with the beam reinforcement deck plate 10 are formed.

In addition, it is possible to reduce construction time and increase construction convenience by installing a window frame or door frame in advance on a mesh-like structure (exo-skeleton).

5 is a view for explaining another construction method according to an embodiment of the present invention. This embodiment uses a method different from the method shown in FIG. 3 in the step of reinforcing the beam reinforcing deck plate 10 after the steps shown in FIGS. 1 and 2. In this embodiment, as shown in Figure 5, using the vertical connection stiffeners 19 such as steel wires or pipes, the transverse reinforcing members 13 are vertical beams 1 positioned on the top of the beam reinforcing deck plate 10. ). Steel wires or pipes exposed to the outside of these steel wires or pipes are removed after the concrete is hardened.

6 and 7 are perspective views illustrating a part of a beam reinforcement deck plate according to other embodiments of the present invention.

Unlike the embodiment shown in FIG. 4, the beam reinforcement deck plate 20 shown in FIG. 6 includes only a transverse reinforcement material 23, and the beam reinforcement deck plate 30 shown in FIG. 7 is a longitudinal reinforcement material. It has only (32). When the area of the building is not large, as shown in FIGS. 6 or 7, a beam reinforcement deck plate provided with only one-way reinforcement may be used.

8 is a perspective view showing a part of a beam reinforcement deck plate according to another embodiment of the present invention. In the embodiment shown in FIG. 8, unlike the embodiment shown in FIG. 7, connectors 46 are formed on the upper surfaces of the protrusions 45 of the plate 41. Accordingly, the longitudinal reinforcing material 42 is exposed upwardly through the connector 46.

In the embodiments shown in FIGS. 1 to 3, it has been described that the transverse reinforcing members 13 are connected with the upper and lower connection stiffeners 18, or the lower transverse stiffener 13 is connected to the upper longitudinal reinforcement 12, but this If the beam reinforcement deck plate 40 of the embodiment is used, the longitudinal reinforcement 42 of the lower beam reinforcement deck plate 40 and the longitudinal reinforcement 42 of the upper beam reinforcement deck plate 40 are formed through the connector 46. They can be connected to each other with the upper and lower connection stiffeners.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes are possible within the scope of the technical spirit of the present invention. It will be obvious to those who have the knowledge of.

For example, although it has been described that reinforcing beams 3 are installed at the top and bottom, beam reinforcement deck plates may be installed.

In addition, in the embodiments shown in FIGS. 1 to 3, it has been described that the beam reinforcement deck plates 10 are supported vertically by the reinforcement beams 3 at the uppermost and the lowermost portions, but the reinforcing beam 3 is only at the uppermost or lowermost portions. You can also install them. For example, the upper beam reinforcement deck plate 10 may be connected to the uppermost reinforcing beam 3, and the lower beam reinforcement deck plate 10 may be connected to and supported by the upper beam reinforcement deck plate 10. In addition, on the contrary, the lower beam reinforcement deck plate 10 is supported by the lowermost reinforcement beam 3, and the upper beam reinforcement deck plate 10 is connected to the lower beam reinforcement deck plate 10 with a vertical connection stiffener 18. Thus, the upper beam reinforcement deck plate 18 may be supported.
