Description

Hollow slab structure and construction method "

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow slab structure, and more particularly, to a hollow hollow slab structure formed by using a paper board inside a slab and a construction method thereof.

In the case of a multi-story building, if shock or vibration is applied to the floor, the noise is not effectively attenuated through the interlayer slab, but is emitted to the lower layer through the slab. Especially, in the case of a multi - story apartment building such as an apartment house, which is a main living space, the noise generated from the upper floor is transmitted to the lower floor, giving an unpleasant feeling. Now, the blocking of the noise is an important factor .

Accordingly, as a countermeasure for solving the interlayer noise problem of the multi-story building, the thickness of the slab gradually becomes thick.

However, if the thickness of the slab of the building is increased, the weight of the slab itself also increases, and the thickness of the lower wall and the column for supporting the slab should also be increased. In this case, not only the amount of concrete used increases but also the construction period and cost increase.

In order to prevent such a problem, a method using a hollow slab having a hollow inside the slab has been implemented.

For example, Korean Patent No. 10-0717766 (entitled: Hollow tube unit for slab and slab including the same) discloses a technique for reducing the weight of a slab by providing a hollow tube inside the slab.

Conventional hollow tubes are made of steel pipes or synthetic resin pipes. In the case of hollow tubes made of steel pipes, they are heavy, expensive to produce, and have poor processability. Hollow tubes made of synthetic resin pipes are not environmentally friendly There is a disadvantage.

In addition, the method of constructing the hollow slab by using the hollow tube is complicated and troublesome, and it takes a long time to reduce the construction efficiency, which is a drawback that the construction cost is substantially increased.

4 is a vertical sectional view of the paper board shown in Fig.

Hereinafter, a hollow slab structure according to an embodiment of the present invention and a construction method thereof will be described with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same elements.

FIG. 1 is a perspective view showing a hollow slab structure according to an embodiment of the present invention, FIG. 2 is a vertical sectional view of the hollow slab structure shown in FIG. 1, and FIG. 3 is a perspective view showing the paper board shown in FIG. 1 And Fig. 4 is a vertical sectional view of the paper board shown in Fig.

1 to 4, a hollow slab structure 100 according to the present invention includes a lower concrete layer 110, a plurality of hollows 120 (see FIG. 1) formed in a concave groove shape on the upper surface of the lower concrete layer 110, A plurality of paper boards 130 covering the plurality of hollows 120 and an upper concrete layer 140 formed on the lower concrete layer 110 and a plurality of paper boards 130, .

Specifically, the lower concrete layer 110 is a base concrete layer formed by curing the concrete for a predetermined period after pouring the concrete to a predetermined thickness.

The plurality of hollows 120 are formed in a concave groove shape having a predetermined depth on the upper surface of the lower concrete layer 110. The plurality of hollows 120 may have a shape extending in parallel to each other at regular intervals. The cross-section of each of the plurality of hollows 120 may have a trapezoidal shape as shown in FIGS. 1 and 2, but is not limited thereto, and may have various shapes such as a quadrangle, a semicircle, and the like.

The plurality of hollows 120 may be formed by providing a mold having a shape corresponding to the shape of the hollow 120 at a position where the hollow 120 is to be formed when the concrete for the lower concrete layer 110 is laid .

The plurality of paper boards 130 are installed on the upper surface of the lower concrete layer 110 so as to cover the plurality of hollows 120. The plurality of paper boards 130 cover the plurality of hollows 120 to prevent the concrete from entering the plurality of hollows 120 when the upper concrete layer 140 is formed. That is, the paper board 130 maintains the shape of the hollow 120 even after the upper concrete layer 140 is formed.

The paperboard 130 may include a honeycomb plate 131 and paper plates 132 and 133 bonded to the bottom and upper surfaces of the honeycomb plate 131.

The honeycomb plate 131 is made of paper and has a plurality of cells 131a arranged in a honeycomb shape. The honeycomb plate 131 has a honeycomb structure in which a plurality of cells 131a are arranged in a honeycomb shape so that the vertical compression strength of the honeycomb plate 131 is higher than that of the honeycomb plate 131. Therefore, It can withstand its weight enough.

The paper plates 132 and 133 are bonded to the bottom and top surfaces of the honeycomb plate 131 to prevent concrete from entering the cells 131a of the honeycomb plate 131, (131). For this, the paper plates 132 and 133 preferably have a thickness of 1 mm or more. The paper plates 132 and 133 may be made of a corrugated cardboard sheet or a laminate in which inks and inks are adhered to each other by an adhesive.

The entire surface of the paperboard 130 may be packed with a waterproof film 134, and the waterproof film 134 may be made of synthetic resin having waterproof property such as vinyl.

Since the paper board 130 is made of paper, if the concrete comes into direct contact with the surface of the paper board 130, moisture inside the concrete penetrates into the paper board 130, . However, if the entire surface of the paperboard 130 is packed with the waterproof film 134, the moisture of the concrete can be prevented from penetrating into the paperboard 130, It is possible to maintain the strength of the metal plate.

The upper concrete layer 140 is formed on the lower concrete layer 110 and a plurality of paper boards 130. The upper concrete layer 140 may be formed by pouring concrete so as to cover the upper surface of the lower concrete layer 110 and the upper surface of the paper boards 130 to a predetermined thickness, and then curing the concrete for a predetermined period of time.

The upper concrete layer 140 may be a lightweight concrete layer made of lightweight concrete or lightweight foamed concrete in order to reduce its weight and alleviate noise.

Although not shown, reinforcing bars may be installed in the lower concrete layer 110 and the upper concrete layer 140, respectively.

A finishing mortar layer 150 may be formed on the upper surface of the upper concrete layer 140 to a predetermined thickness. The finished mortar layer 150 may be made of lightweight mortar or lightweight foamed mortar.

The hollow slab structure 100 according to the present invention having the above-described structure is constructed by using the paper board 130, particularly the paper board 130 made of the honeycomb plate 131 and the paper boards 132 and 133, And a hollow 120 is formed in the substrate 100.

Therefore, compared to the case of forming a hollow by using a conventional steel pipe or a synthetic resin material pipe, the material cost is low and the weight is light, and the construction time is short and the construction cost is simple. There is an advantage to be able to do.

Also, the honeycomb plate 131 and the paper plates 132 and 133 of the paper board 130 can be manufactured by recycling waste paper, which is also environment-friendly.

Hereinafter, a construction method of the hollow slab structure 100 having the above-described construction will be described.

In detail, a plurality of hollows 120 are formed in a concave groove shape having a predetermined depth on the upper surface of the lower concrete layer 110 while forming the lower concrete layer 110. The lower concrete layer 110 may be formed by pouring the concrete to a predetermined thickness and then curing the concrete for a predetermined period of time. At this time, if a mold having a shape corresponding to the shape of the hollow 120 is formed at a position where the hollow 120 is to be formed, a plurality of molds may be formed on the upper surface of the lower concrete layer 110 simultaneously with the lower concrete layer 110. A hollow 120 may be formed.

Next, a plurality of paper boards 130 are installed on the upper surface of the lower concrete layer 110 so as to cover the plurality of hollows 120.

3 and 4, the plurality of paper boards 130 are prepared by preparing a honeycomb plate 131 having a plurality of cells 131a arranged in a honeycomb shape and made of paper, And by adhering paper plates 132 and 133 to the bottom and top surfaces of the comb plate 131. The paper plates 132 and 133 may be made of corrugated cardboard or a laminated paper having a thickness of 1 mm or more. In addition, the entire surface of the paperboard 130 can be packed with the waterproof film 134, and a synthetic resin material having waterproof property such as vinyl can be used as the waterproof film 134.

Next, as shown in FIGS. 1 and 2, an upper concrete layer 140 is formed on the lower concrete layer 110 and the plurality of paper boards 130. The upper concrete layer 140 may be formed by pouring the concrete so as to cover the upper surface of the lower concrete layer 110 and the upper surface of the paper boards 130 to a predetermined thickness, and then curing the concrete for a certain period of time.
