Deck Plate Using Sandwich Panel {DECK PLATE USING SANDWITCH PANNEL}

The present invention relates to a deck plate using a sandwich panel, and more particularly, by combining a sandwich panel and a truss girder filled with insulation, flame retardant, soundproofing material, etc., while maintaining the advantages of the existing deck plate, insulation, flame retardant, sound insulation, etc. It is a deck plate that requires no additional finishing work or formwork disassembly to add functionality.

In general, the majority of building structures are constructed using reinforced concrete. The building structure using reinforced concrete is a composite structure in which a combination of concrete and compression material is used together.It can be obtained by repeating the process of dismantling the formwork after reinforcing the formwork and reinforcing the reinforcement and pouring concrete. have.

However, according to the conventional technology, there is a problem in that a large amount of air is required due to the construction step of installing formwork with plywood, lumber, etc., and performing the reinforcement work such as reinforcing bars, and the dismantling work of dismantling the formwork after curing of concrete. .

In order to solve this problem, a formwork having a deck plate form that can support the weight of the concrete itself generated during the process of curing concrete and concrete that is placed between the beams, which are structures for constructing buildings, or Dice panels have been proposed. Such deck plates have the advantage of easy installation and mass production. In addition, the cost savings can be achieved by applying the plain support method to the deck plate.

However, the conventionally proposed deck plate has a problem that is not only insulated, heat-insulating function, but also vulnerable to noise and fire, and needs to dismantle the formwork or formwork panel separately, which requires a lot of air.

The present invention is to solve the problems of the prior art as described above, by combining the truss girder on a sandwich panel filled with insulation, flame retardant, soundproofing material, etc., a separate finishing work for functions such as insulation, flame retardancy and sound insulation Let's provide a deck plate that's not needed at all and that doesn't even need to be dismantled.

Deck plate using a sandwich panel according to an embodiment of the present invention for solving the above problems, Sandwich panel comprising a layer filled with at least one of the insulation, heat-resistant material, non-combustible material or sound insulation between the upper panel and the lower panel; And a truss girder fixed to the upper panel of the sandwich panel, wherein the upper panel may be formed of reinforced plastic or wood.

The truss girder is preferably composed of an upper reinforcing bar, a lattice material which is opened downward toward the center of the upper reinforcing bar and welded to the upper reinforcing bar, and a pair of lower reinforcing bars welded to the lower side of the lattice material.

Preferably, as another embodiment for coupling the truss girder to the sandwich panel, it may further include a fixing member for fixing the lower reinforcing bar to the upper panel. At this time, the fixing member, the U-shaped fixed body formed with a through hole through which the lower reinforcing bar transversely, and the lower portion of the leg portion of the fixed body penetrates the leg portion of the fixed body in contact with the upper panel upper surface It may include a piece that is fastened to the upper panel.
