Description

[0001] DEAK PLATE FOR CONSTRUCTION [0002]

The present invention relates to a buried deck plate, and more particularly, to a deck plate that can prevent damages and deformation of a deck plate during a construction process and can prevent leakage of water after installation.

In the case of building a traditional building structure, it is made of a reinforced concrete slab structure in which concrete is placed and cured after arranging reinforcing bars. However, this conventional method requires a lot of construction time and cost, It is not easy to construct a high-rise building.

In order to solve such a problem, recently, it has been proposed and used to construct a slab of a building by using a deck plate. Such a deck plate is formed by a built-in type in which a slab is left united with a slab, And then removed.

The deck plate as described above is formed by molding a metal plate having a predetermined width and length so as to hold a truss girder which functions as a reinforcing bar while also acting as a form for constructing a slab in a steel structure.

Various types of deck plates have been developed and used. The deck plates are classified into a type in which a fixed foot and a deck plate constituting a truss girder are fixed by welding, and a type in which a fixed foot constituting a truss girder is inserted and held in a deck plate.

Hereinafter, a representative structure of a deck plate of the type in which the tension girder is welded is described with reference to FIG.

The deck plate 1 to which the prior art is applied is formed by connecting hooks 2 and 3 of male and female bodies so as to be connected to the deck plate 1 at the adjacent positions on both ends of the metal plate, And a plate body (4).

In the middle of the plate body 4, the truss girder 6, which serves as a core of the slab, is fixed by welding by fixing the fixing ribs 5 upwardly while keeping equal spacing.

The truss girder 6 fixed by welding with the fixed rib 5 is formed by a pair of reticle bars 7 formed repeatedly so as to have concave and convex portions and an upper reinforcing bar 8 connected to the upper portion of the reticle bar 7 in the longitudinal direction A lower reinforcing bar 9 connecting both sides of the intermediate portion of the reticle, and a fixing foot 10 protruding from both sides of the lower end of the reticle bar 7.

The fixing rib 5 of the deck plate 1 and the fixing foot 10 of the truss girder 6 are fixed by welding so that the deck plate 1 and the truss girder 6 are united to integrate the concrete, So that no phenomenon occurs.

Patent No. 10 - 0751502 - 0000 Patent No. 10 - 1029102 - 0000 Patent No. 10 - 1151066 - 0000 Patent No. 10 - 1481480 - 0000

The deck plate to which the conventional technique as described above is applied may have various shapes of the fixed ribs, but the deck plate may simply be bent and simply protruded in a truncated (∧) or arcuate shape (∩) And the deck plate is often damaged in the process of welding due to the relatively thin thickness of 0.5 ~ 1 mm as compared to the fixed foot of the truss girder.

In the process of fixing the truss girder and the deck plate by welding, the deck plate of a thin thickness is easily deformed to fail to maintain the shape, and the deck plate at the welding position is melted to generate holes, It is difficult to maintain a stable state of the truss girder.

In the case of deformation such as deflection of the deck plate during the welding process, the truss girder fixed to the deck plate is excessively spaced above the deck plate, making it difficult to obtain the strength of the slab in a steady state by the concrete curing, The deformed deck plate is exposed as it is, and the appearance is damaged.

In the process of fixing the deck plate and the truss girder as described above, welding heat and gas are exposed to the surface of the deck plate to cause discoloration and unevenness, so that the surface aesthetic appearance of the deck plate exposed after completion of the slab is not cleaned.

In particular, when a hole is formed in the deck plate, the truss girder at the hole forming position can not be firmly held, so that the truss girder is displaced in the process of pouring the concrete. Therefore, it is difficult to ensure uniform durability of the slab after the concrete curing And in case of severe damage, the disengaged truss girder is exposed to the upper part of the slab.

In addition, in the process of pouring the concrete, concrete flows down through the holes formed in the deck plate, and moisture, etc., leaks from the concrete, causing the strength of the slab at the hole to be weakened. The connection hook formed for connection is simply retained in the hooked state, thereby providing a cause for leakage from the upper side of the deck plate through this portion.

In addition, after the curing of the concrete in which the hole forming part is laid is completed, since the hole part is exposed as it is, there are various problems such that the aesthetic pipe is damaged as well as the hole forming part is corroded or oxidized and becomes weak with time It is true.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a metal plate, which comprises a left connecting hook formed on both sides of a plate body of a metal plate, a right connecting hook, and a fixed rib protruding upward to fix the truss girder. A deck plate;

The left connecting hook includes a first left bending portion bent in an inward direction of the plate body, a left left bending portion extending downwardly inclined from the left first bending portion, a left bending portion bending in a direction outside the plate body from the left- And a left rectilinear portion protruding from the left 2-bending portion toward the outside of the plate body; The right hook has a right bending portion bent in an inward direction of the plate body, a right bending portion extending upward from the right bending portion, a right bending portion bending in the outward direction of the plate body from the right bending portion, , And a right-side line portion protruding from the right-side 2-folded portion in the outward direction of the plate body;

Further comprising a waterproof means for increasing the adhesion and airtightness and preventing the flow and the leakage of water on the inner surface portion connected to each other when the left and right connection hooks are engaged;

It is possible to prevent the deck plate from being deformed and damaged while increasing the coupling force with the truss girder and to prevent the discoloration and deformation of the plate material due to the welding heat and the welding gas while being able to eliminate the leakage phenomenon in the concrete casting process .

The present invention improves the deck plate to prevent deformation and damage of the deck plate even when welding is performed to maintain the truss girder, thereby improving the rigidity of the deck plate itself as well as improving the durability of the finished slab, Effect.

It is also possible to improve the quality and durability of the deck plate by improving the connection hooks formed at both ends for connection with the adjacent deck plate, have.

And it is possible to prevent the deck plate from being damaged, deformed or discolored due to the high temperature and harmful gas generated in the process of welding the deck plate and the truss girder.
