Abstract
Description
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.
