Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a hollow slab type deck plate structure that does not require a flotation prevention device, and a hollow slab type deck plate structure without anti-

More particularly, the present invention relates to a hollow slab type deck plate structure, and more particularly, to a hollow slab type deck plate structure, and more particularly to a hollow slab type deck plate structure, And a method of easily constructing a hollow slab type deck plate structure and a plurality of lightweight molding materials integrally with each other without requiring a flotation prevention device.

Generally, the reinforced concrete structure applied to the floor of each tier of a high-rise building, the bridge roof, etc. is a composite structure that uses concrete as a compression material and reinforcing bars as a tensile material. When reinforcing concrete structures are built, generally formwork is formed to form the outer surface of concrete. Reinforcement is placed on the formwork to match the design strength of the structure, concrete is laid, and the formwork is removed when the curing is completed.

The reinforced concrete method is a structure that uses complementary characteristics of reinforcing steel and concrete as a method of using the tensile characteristics of steel and the compression resistance of concrete. Reinforced concrete structures require a relatively large amount of air and workforce, such as plywood and slabs, which are then used to reinforce the reinforcing bars and to remove the formwork when the curing process is completed. It is incapable of recycling, resulting in waste of materials and industrial waste caused by waste materials.

In order to solve the above disadvantages, the proposed method uses a deck plate having a generally large curved cross section as a non-molding method. The use of the deck plate eliminates the need for construction and disassembly of the formwork, reduces the generation of industrial waste, facilitates wiring work and piping in the lower bend, enables safe work, and shortens the overall construction period.

The conventional deck plate structure is composed of a plate member in which protrusions and recesses are continuously formed, and an attaching member that is attached to the recessed portion of the plate member and improves the adhesion of the concrete.

However, such a conventional deck plate structure has a problem that a large amount of concrete is consumed and its weight is also increased because concrete is laid throughout the deck plate. Thus, since the conventional deck plate structure is relatively heavy, there is a problem in application to high-rise buildings in which stability and robustness are required. Therefore, a deck plate structure capable of reducing weight while maintaining stability and rigidity is in desperate need.

To solve these problems, the prior art Patent No. 10-0779900 ("hollow-type slab structure using a hollow member for a deck plate and its construction method") is known. As shown in FIG. 1, the prior art has a structure in which a hollow member is fixed to a deck plate and then a concrete is laid to reduce the weight of the bottom plate.

However, in the prior art, since the hollow member must be separately fixed by using a deck plate having a T-bar, it is not only troublesome but also has a limitation in that stress is concentrated by forming a sharp angle at the corner of the hollow member .

Disclosure of Invention Technical Problem [8] The present invention has been made in order to solve the above-mentioned problems of the related art, and its object is as follows.

First, the present invention has a synergistic effect by combining a deck plate and a hollow slab technology, and particularly, a lightweight molding material is installed between truss girders coupled to a deck plate, and even when such a lightweight molding material is not fixed to a separate fire prevention device, And an object of the present invention is to prevent an injured person from being caught by an orthogonal vicinity when the vehicle is cast.

Secondly, it is another object of the present invention to prevent the concentration of stress by rounding round edges of the lightweight molding material, and to improve the workability by assembling a plurality of lightweight molding materials into one assembly and applying them to the field.

Thirdly, it is another object of the present invention to make it easy to identify cracks and leakage occurrence positions by enabling demoulding after the deck plate is used as a mold substitute.

According to an aspect of the present invention, there is provided a deck plate, A plurality of truss girders provided on the upper surface of the deck plate and spaced apart from each other by a predetermined distance, the upper and lower reinforcing bars being connected to the lattice frame to form a triangular cross section; A plurality of spacers interposed between the deck plate and the truss girder to fix the deck plate and the truss girder in a spaced apart state; A plurality of lightweight forming members arranged continuously in the longitudinal direction between adjacent truss girders; An orthogonal vicinity of the upper reinforcing bar of the truss girder; And a lattice girder of the truss girder is bent at a bending point where it meets with the upper and lower reinforcing bars, and orthogonally near and perpendicular to each other are respectively disposed on the deck plate, Shaped deck plate structure in which a plurality of lightweight molding materials are prevented from buoyancy by engaging in the vicinity of an orthogonal phase when the concrete is poured onto the concrete slab.

According to another aspect of the present invention, there is provided a truss structure, comprising: a first step of installing a deck plate coupled with a plurality of truss girders and spacers between structures; A second step of arranging orthogonally near the lower reinforcing bar of the truss girder; A third step of arranging a plurality of lightweight molding materials between adjacent truss girders; A fourth step of arranging an orthogonal neighborhood on the upper reinforcing bar of the truss girder; And a fifth step of pouring and curing the concrete after placing the concrete on the deck plate on which the lightweight molding material is disposed. The present invention provides a method of constructing a hollow slab deck plate structure that does not require a float prevention device.

According to the present invention, the following effects are expected.

First, since the lightweight molding material is prevented from being lifted up by the orthogonal vicinity of the truss girder coupled to the deck plate without requiring a separate injury prevention device, the workability is improved.

In other words, although the conventional hollow member (lightweight molding material) has to be fixed to a separate float prevention device in order to prevent floatation due to the concrete insertion pressure, the present invention is characterized in that the upper surface of the lightweight molding material is caught near an orthogonal phase, So that a separate injury prevention device is not required.

Secondly, since a lightweight molding material disposed between adjacent truss girders is provided as one assembly, a plurality of lightweight molding materials can be easily installed at one time and thus the workability is greatly improved.

In addition, such a lightweight molding material has rounded corners to prevent stress concentration, thereby improving structural performance.

Third, the concrete can be demolded after the concrete with the hollow slab type deck plate is cured, so that the steel sheet can be recycled and the economic efficiency can be improved.

Furthermore, when the deck plate is demoulded, the lower surface of the poured concrete is visible, so that cracks and leaks can be confirmed, which can be suitably used in underground parking lots and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is based on the synergy effect of combining the two techniques of hollow slab and deck plate 100. Particularly when the lightweight molding material 400 does not require a separate float prevention device, .

FIGS. 2A to 2E illustrate a construction process of a structure of a hollow slab type deck plate 100 in which a float prevention device according to the present invention is not required. FIG. 3 (a) FIGS. 4A to 4D show various embodiments of the lightweight molding material 400 in the structure of the hollow slab-type deck plate 100 in which the float prevention device according to the present invention is not required.

FIG. 5 illustrates an embodiment of a structure of a hollow slab-type deck plate 100 in which the float prevention apparatus according to the present invention is not required.

Specifically, the present invention relates to a deck plate (100); The upper and lower reinforcing bars 220 and 240 and the lattice frame 260 are coupled to each other at a predetermined distance from the upper surface of the deck plate 100 to form a plurality of truss girders 200 ); A plurality of spacers 300 interposed between the deck plate 100 and the truss girder 200 to fix the deck plate 100 and the truss girder 200 in a spaced apart state; A plurality of lightweight molding materials 400 arranged continuously in the longitudinal direction between adjacent truss girders 200; An orthogonal neighborhood 500 latticed over the upper reinforcing bars 220 of the truss girder 200; And an orthogonal substructure 600 disposed on the lower reinforcing bar 240 of the truss girder 200. The lattice frame 260 of the truss girder 200 includes upper and lower reinforcing bars 220 and 240 When the concrete C is laid on the deck plate 100, the plurality of lightweight molding materials 400 are arranged in a direction perpendicular to the orthogonal upper and lower sides 500 and 600, Is characterized in that buoyancy is prevented by engaging with the quadrangular pyramid (500).

The deck plate 100 is a plate member formed by a waveform used in a floor structure and has a rigidity and a rigidity in an out-of-plane direction by forming a cross-section into a trapezoid or a square shape. Means a plate having increased buckling resistance in the direction of the arrow.

The truss girder 200 is attached to the deck plate 100 by attaching a spacer 300 to the upper surface of the deck plate 100 at every predetermined position. 5, the deck plate 100 may be detachably coupled to the spacer 300. After the concrete C is cured, the bolts fastened together with the spacer 300 and the deck plate 100 are disassembled . The deck plate 100 thus demolded has an advantage of being economically advantageous not only by recycling the steel plate but also by observing the lower surface of the cured concrete (C), thereby facilitating confirmation of cracks and leakage .

The spacer 300 may be made of a metal or a plastic material and fixes the truss girder 200 and the deck plate 100 to be spaced apart from each other.

The truss girder 200 is spaced apart from the upper surface of the deck plate 100 in the longitudinal direction and is composed of an upper reinforcing bar 220, a lower reinforcing bar 240 and a lattice muscle 260, . In other words, the truss girder 200 is connected to the upper reinforcing bar 220 and a pair of lower reinforcing bars 240 arranged parallel to the lower reinforcing bar 220 by a curved lattice root 260 to form a triangular cross-section.

An orthogonal neighborhood 500 and an orthogonal neighborhood 600 are abutted on the upper reinforcing bar 220 and the lower reinforcing bar 240 of the truss girder 200 in the orthogonal direction. At this time, a lattice-shaped space is formed by the upper and lower reinforcing bars 220 and 240 and the vicinity of the upper and lower reinforcing bars 220 and 240, and the lightweight molding material 400 is placed in the space.

The lightweight molding material 400 is a member installed between adjacent truss girders 200 and reduces the weight of the concrete C placed on the deck plate 100 to reduce the weight thereof. The lightweight molding material 400 is preferably formed of styrofoam in consideration of heat insulation and ease of fabrication. However, the lightweight molding material 400 may be formed of various materials including plastic or the like.

Meanwhile, the lightweight molding material 400 may be manufactured in the form of a housing as shown in FIGS. 2d and 2e. At this time, it is preferable that the lower surface is made flat and is stably fixed on the upper surface of the deck plate 100 and the upper surface is also made flat. This is because when the lightweight molding material 400 is lifted due to the placement of the concrete C, So that the surface can be reliably stuck to the orthogonal neighborhood 500. In particular, lightweight molding material 400 is preferably arranged such that the plane center between adjacent orthogonal subframes 600 lies on the same line as the orthogonal neighborhood 500, 220 and the orthogonal neighborhood 500 should be butt-coupled. The side surfaces of the lightweight molding material 400 may be convex so as to protrude beyond the center height of the lightweight molding material 400. This is because when the lightweight molding material 400 is disposed between the adjacent truss girders 200, So as to prevent the phenomenon of flowing to the left and right when the concrete (C) is poured. Further, it is preferable that the lightweight molding material 400 is rounded so that each corner is rounded. This smoothes the casting of the concrete C and prevents the concentration of stress on the corner portion.

3 (a), a plurality of lightweight molding materials 400 may be preliminarily connected to each other and disposed between adjacent truss girders 200. As shown in FIG. 3 (b), the lightweight molding material 400 may further include a plate-shaped hooking part 400a which is formed to have a predetermined cross-section on the upper surface. An embodiment in which a plurality of such lightweight molding materials 400 are connected is shown in FIGS. 4A to 4D. As shown in FIG. 4B, a branch 420 for linearly connecting the hooking part 400a, The plurality of lightweight molding materials 400 may be connected in the longitudinal direction by the side connection portions 440 that are three-dimensionally protruded from the respective side surfaces of the lightweight molding material 400. The plurality of lightweight molding materials 400, the hooking parts 400a and the branching parts 420 manufactured in the shape of FIG. 4b are all made of plastic, and the plurality of lightweight molding materials 400 manufactured in the shape of FIG. And the side connecting portion 440 may all be made of styrofoam.

4A, a plurality of lightweight molding materials 400 may be connected by forming the branch portions 420 and the side connection portions 440 together in the lightweight molding material 400 provided with the hook portion 400a . At this time, the lightweight molding material 400 is made of styrofoam, and the hooking part 400a and the branching part 420 can be made of plastic.

As described above, since the plurality of lightweight molding materials 400 are integrally manufactured and used in the field, the workability is greatly improved and the construction period can be shortened.

4D, when the lightweight molding material 400 is connected to the hanging part 400a and the branches 420 and is vertically and horizontally connected, the upper reinforcing bars 220 of the truss girder 200 So that the construction can be more easily carried out. This is because the legs 420 are positioned between the upper reinforcing bars 220 and the orthogonally upper side 500 to prevent injuries.

The construction method of the structure of the hollow slab type deck plate 100 in which the above-described float prevention device is not necessary can be seen from FIGS. 2A to 2E. As shown in FIG. 2, the truss girder 200 and the spacer 300, A first step of installing the plate 100 between the structures; A second step of arranging the orthogonal vicinity 600 on the lower reinforcing bar 240 of the truss girder 200; A third step of arranging a plurality of lightweight molding materials 400 between adjacent truss girders 200; A fourth step of placing an orthogonal vicinity 500 on the upper reinforcing bar 220 of the truss girder 200; And a fifth step of pouring and curing the concrete C onto the deck plate 100 on which the lightweight molding material 400 is placed.

The method of the present invention may further include a sixth step of separating the deck plate 100 from the spacer 300 after the curing of concrete C after the fifth step.

Such a construction method is the same as that of the deck plate 100 described above, and thus a detailed description thereof will be omitted. However, since the lightweight molding material 400 in the third stage is manufactured in a plurality of longitudinally and laterally connected shapes, it is brought into the site and is cut between the adjacent truss girders 200 by cutting one line in the field, thereby greatly improving the workability.

Briefly, the structure and construction method of the hollow slab type deck plate 100, which does not require the float prevention device according to the present invention, can attain light weight while maintaining the stability and robustness of the slab, It is possible to provide the heat insulating effect according to the material of the lightweight molding material 400 as well as the inherent functions of the material 100 itself, thereby saving energy. In addition, since the hollow slab is formed by using the lightweight molding material 400 together with the deformation type deck plate 100 structure, it is possible to confirm the position of the water leakage and the crack after the construction, and the steel sheet can be recycled and economical effect can be obtained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

It is therefore intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
