The present invention relates to a deck plate of a deck panel for a concrete slab, and more specifically, the adhesive force with the concrete slab can be increased, improve the structure of the connection portion is easy to work with the adjacent deck plate, watertightness of the connection portion It relates to a deck plate of a deck panel for a concrete slab so that this can be improved.

The most common method of constructing reinforced concrete slab in a general reinforced concrete structure is to form a formwork to form the outer surface of the concrete and a copper support supporting the formwork, and to reinforce the reinforcement on the formwork and then cast the concrete. After that, if the concrete is cured through a curing process for a period of time is made of a process for removing the formwork and copper bar.

However, this method requires a lot of manpower and work according to the construction and dismantling of the formwork and copper barrier, and it is necessary to perform separate reinforcement work, and finish work due to the surface defect of the structure when removing formwork after concrete curing. There is a lot of problems, such as the need for a considerable amount of air, and the economic feasibility due to the generation of waste materials due to form damage during form dismantling.

Therefore, in recent years, a slab of reinforced concrete is formed by using a deck plate composed of a deck plate serving as a formwork and a truss girder installed to maintain the strength of the slab on the deck plate, without using a circle and formwork. Deck slab method is mainly used.

1 is a perspective view showing the overall configuration of a deck panel commonly used in the prior art.

As shown in the drawing, a conventional general deck panel has a deck plate 100 having a predetermined thickness designed to withstand the weight and construction load of concrete sufficiently, and a truss fixed in the longitudinal direction on the upper surface of the deck plate 100. It is made of a girder 200.

The truss girder 200 is installed on the lattice reinforcement 210 continuously bent along the longitudinal direction with a constant waveform, and installed in the upper and lower portions of the lattice reinforcement 210 and installed in the longitudinal direction of the deck plate 100, respectively, It is made of reinforcing bars (220, 230) to secure the tensile strength, the foot (212) is formed in the bottom of the lattice reinforcement 210 is bent horizontally welded to the rib (110).

Deck plate 100 serves to bear the tensile load of the slab as well as the formwork, the surface is plated with zinc in order to prevent corrosion caused by contact with the concrete, the lattice of reinforcement 210 Ribs 210 on which the foot 212 is placed are formed at regular intervals in the width direction, and both ends of the width direction are connected to another neighboring deck plate so that the deck plate can be continuously arranged as required by the joint. 120 and 120 'are formed, respectively, and the conventional general structure of such a joint 120 and 120' is shown in FIG.

That is, Figure 2 is a front view showing a conventional deck plate connection structure, the connection structure of the conventionally known joint is a so-called hook type structure, at each end of one deck plate and the other deck plate adjacent to it The hooked joints 120 and 120 'are bent to face each other so that the bent ends of these joints overlap each other and are connected.

However, in this type of connection structure, even if the bending angle of each joint is slightly different at the time of joining, it is easy to create a gap in the joint part because the bent contact surface of each joint is point contact or line contact rather than the surface contact, and through the gap, There was a problem that the water of the concrete poured in the leak down.

In addition, the joint bent in the shape of the hook simply connected to the overlapping structure, there is a problem that the joint strength of the joint portion is not strong, structural stability is lowered and the leaking space is easily formed.

Therefore, an improvement of the deck plate has been proposed to solve such a problem, and the prior art has disclosed Korean Patent Application Nos. 2004-0098988, 2004-0027555, and 2004-0020969.
