Truss deck panel for slab

The present invention relates to a truss deck panel for building slab, by installing the deck plate formed with T-shaped reinforcement ribs, to prevent deformation of the deck plate during construction, reinforcing the structural rigidity of the deck panel It relates to a truss deck panel. In addition, the truss deck panel for the construction slab of the present invention installs a single 'Ω' type lattice material in one direction at regular intervals, thereby fulfilling the structural role of the lattice material required for the construction slab, while saving material during construction. The present invention relates to a truss deck panel for a construction slab having high workability, which can maintain excellent quality at a construction site without welding, rebar processing, etc. at a construction site.

Generally, the reinforced concrete structure that makes up the main structure of a building is a composite structure in which concrete, which is a compressive material, and reinforcing material, which is used as a tensioning material, is used together.It is a form that forms the outer surface of concrete, reinforces the steel on the form, and then places concrete. When curing is completed, the process consists of removing the formwork.

Such a structure requires considerable air due to the construction work for installing formwork with plywood, lumber, and the like, and the dismantling work for dismantling the formwork after curing of concrete. In particular, the structure has good adhesion between the concrete surface and the formwork, which is difficult to separate it during the dismantling of the formwork. Accordingly, a separate surface finishing work is required due to the failure of the structure surface. Formwork has a problem in that it is difficult to reuse due to damage during the dismantling operation, causing a large amount of construction waste materials.

As one of the improvements to the prior art, a method of using the structure used to form the exterior of concrete instead of the formwork as it is part of the reinforced concrete structure has been proposed. The most widely used of these methods is the method of using the deck panel.

Since the installation work is performed by simply covering the deck panel between beams, it is not necessary to install and dismantle the formwork, and to install wiring and piping such as electricity and notification facilities in the lower bend, and no additional finishing work is required. It has been widely used in the construction of slab floors in large buildings in recent years due to the advantages of providing a safe working space for the installation of a separate safety net. However, these deck panels are only required to install and dismantle the formwork compared to the prior art, and additional reinforcement is required for the firm settlement between the surface of the deck panel and the concrete, which is a flat surface, and thus additional air input is indispensable. In addition, the reinforcement process has a problem that it takes a lot of air, just as in the general formwork process.

Conventional deck panel (D) as shown in Figure 1 designed to solve the above-described problems are provided with two lattice material 21 facing inclined outwardly of the upper and lower roots 22 and 23 The installation work is completed by joining the deck girder 20 is formed on the deck plate 10 to form a deck panel (D), and after the concrete curing, the deck plate 10 is a finishing material as it is air of the slab structure construction It has the effect of shortening (separate reinforcement process is unnecessary) and cost reduction by construction. In addition, the deck panel (D) is a vertical fixation muscle 32 and the upper end is connected to the upper root 22 and the horizontal fixation muscle 32 is connected to the horizontal fixation muscle 32 and the vertical fixation muscle extending downward The '+'-shaped fixing part 30 composed of 31 is formed, thereby preventing the strength and deformation of the deck panel D to form a more stable deck panel (D).

However, the deck panel D as described above has a structure in which the lattice material 21 of the deck girder 20 constituting the deck panel D is opposed to each other, so that material loss due to excessive consumption of the lattice material 21 is achieved. Due to the increase in the number of welding welds to the welding work is a factor that increases the manufacturing cost, and forms a space between the opposed lattice material 21 of the deck girder 20, the inflow of aggregate during concrete injection There is a problem that is not easy. In addition, the deck panel (D) as described above, in order to achieve a predetermined structural performance for achieving the purpose as a truss deck panel for building slabs, the fixing portion 30 for receiving the upper and lower roots 22 and 23. Since it must be installed, the construction process for installing it is increased, the workability is lowered, the manufacturing cost is raised, there is a problem that the air is delayed. In addition, the deck panel (D) as described above has a problem in that the deck plate 10 itself lacks rigidity, so that distortion or deflection occurs during transportation or construction, and thus the construction is not smooth.

The truss deck panel for the construction slab devised to solve the above problems is to install a deck plate formed with T-shaped reinforcement ribs, to prevent deformation and deflection of the deck plate during construction, the upper and lower It is an object of the present invention to provide a truss deck panel for a building slab, which can reduce the construction process because there is no need to install a separate fixing part for fixing.

In addition, the truss deck panel for the construction slab of the present invention installs a single 'Ω' type lattice material in one direction at regular intervals, and performs a structural role as a lattice material required for the building slab, It is aimed at providing truss deck panel for construction slab with high workability that can save material by reducing the number of lattice materials used, and there is no work such as welding or rebar processing at construction sites and can maintain excellent construction quality at construction sites. .

At this time, the T-shaped reinforcing rib 111 is composed of a horizontal portion (111b) and the vertical portion (111a), reinforces the rigidity of the deck plate 110 itself, the deck plate at the time of transport or construction ( 110) to prevent deformation and sag. In addition, between the horizontal portion 111b and the vertical portion 111a of the T-shaped reinforcing rib 111, a predetermined size space 111c is formed therethrough, so that the reinforcing rib 111 is more stable. To achieve. In addition, although the space 111c formed below the horizontal portion 111b of the reinforcing rib 111 is shown as an inverted triangle, the structure of the reinforcing rib 111 may be stabilized. If it is a form, it can be transformed into another form. In addition, as shown in FIG. 5, a groove 111d (not shown) having a predetermined size may be formed on an upper portion of the horizontal reinforcement rib 111 of the deck plate 110.
