Description

Deck Panels {Deckpanel}

The present invention relates to a deck panel, and more particularly, to a deck panel provided by changing the structure of the truss girder in the bone portion of the corrugated deck plate.

The deck panel slab method is widely used in the construction of floors and ceiling concrete slabs of large buildings. Looking at the overall construction of these deck panels, the deck panels are designed to withstand the concrete's own weight and construction load. It consists of a deck plate (deck steel plate) serving as a formwork of a predetermined thickness and a plurality of truss girder (fixed steel plate) fixed to the upper surface of the deck plate in the longitudinal direction to maintain the strength of the concrete slab, Truss girder is mainly used triangular truss girder. Deck panels that play such a role are used by combining a plurality of deck panels according to the area of the building.

Deck plate acts mainly as formwork during construction, and after construction, it becomes the surface of concrete slab structure.The surface is plated with zinc to prevent corrosion caused by contact with concrete, and the foot of corrugated lattice rebar Ribs, which are placed welding ribs, are formed at regular intervals in the width direction, and female and joint portions are formed at both ends of the width direction in order to continuously arrange a plurality of deck plates by the required area of the building. Are formed respectively. Such deck plates are of flat plate type or corrugate plate type.

The truss girder is a pair of corrugated lattice bars that are continuously bent along the deck plate in a constant wave form along the longitudinal direction of the deck plate, and the upper reinforcing bar welds the top of the pair of corrugated lattice bars. And the lower reinforcing bars respectively installed under the pair of corrugated lattice reinforcing bars, wherein the upper and lower reinforcing bars form a triangle, and are installed in the longitudinal direction of the deck plate, respectively, wherein the upper and lower reinforcing bars are reinforced with corrugated lattice reinforcing bars. As the reinforcing bars, the main slab of the concrete slab is used to maintain the overall strength of the concrete slab, and a foot is formed at the bottom of the corrugated lattice reinforcing bar to be horizontally bent and spot welded to the rib of the deck plate.

Thus, both ends of the horizontal bar are welded to the lower rebars of the truss girder, which is installed on the top of the deck panel to form a triangle, and the upper ends of the vertical bars are welded to the upper reinforcement, so that the horizontal bar and the vertical bar crosswise, and the intersection of the horizontal and vertical bars is welded. Horizontal and vertical rods are fixedly connected.

The deck panel having the structure as described above is transported to the construction site by a vehicle, and a plurality of deck panels are coupled to each other by the connecting portion of the deck plate according to the area of the building, and both ends are mounted on the beam (beam) and the beam (beam) facing each other. The lower end is fixed to the upper surface of the beam (beam) by welding.

After the concrete is placed on the upper surface of the deck panel installed in this way, the concrete slab that forms the floor and ceiling of the building is constructed after a certain period of curing. The vertical rod is to prevent the deck plate is pushed out of the beam (beam) by the pouring pressure during concrete pouring.

The truss girder of such a shape is installed in the case of a corrugated deck plate, the foot of the corrugated lattice reinforcement is mounted on the bottom of the bone.

The components of the deck panel and the installation structure of the above-mentioned components are registered in Korean Patent No. 0180079 (Decks Girder of Reinforced Concrete Slab), Korean Utility Model 20-0146601 (beam coupling structure of Deck Panel), and Korean Registered Patent 10-729860 (Triangle Truss Type Deck Panel End Structure).

And in the steel structure, in the case of I-beams (beams), as described in the Republic of Korea Utility Model No. 20-0146601, the beam (beams) between the deck panel and the deck panel vertically welded to the I-beams (beam) ), One row (beam center) or two rows (beams) acting as shear connectors so that the concrete placed in the beams is fixed so that the beams and the concrete slab behave integrally. Stud bolts (both sides of the beam) or stud bars connecting deck panels are provided.

In addition, in the case of TSC (T-type Steel Composite beam) composite beam, instantaneous electric welding by a stud gun as a shear connector on both upper flanges of TSC composite beam, as disclosed in Korean Patent Registration No. 10-0592398 (bottle top flange TSC beam) The stud is installed.

The structure of the conventional deck panel as described above has the following problems.

First, the resistance to the load of concrete poured during construction is determined by the upper reinforcement of the truss girder under compression. Looking at the structure of the truss girder, one of the upper reinforcement under compression is low in strength due to its low cross-sectional area. There are two bottom reinforcing bars, which have a large cross-sectional area, and the arrangement structure of the high-strength upper and lower reinforcing bars is unreasonable, which lowers the resistance to concrete loads.

Second, since the stress moment acting on both ends of the deck panel of the hardened concrete slab after construction is greater than the stress moment acting on the center of the deck panel, the upper rebar is placed more than the lower rebar or the upper rebar is The thicker than the lower reinforcing bar should be used, but the upper and lower reinforcing bars are used with the same thickness, so the durability of the building is lowered and the resistance to earthquake loads is reduced.

Third, the flat or corrugated deck panel is installed on the upper surface of the beam, and the truss girder is a structure for maintaining the overall strength of the concrete slab as the main root of the concrete slab. As concrete should be cast to have a sufficient coating thickness, the thickness of the concrete slab becomes thicker, which limits the height of the concrete slab at a limited building height.

Fourth, stud bolts installed on the upper flange of I-beams used as shear connectors and studs installed on the upper flanges of TSC composite beams result in increased labor and cost increase, and the stud bar is connected to the truss girder physically and continuously. As a result, the resistance to shear force will be improved rather than stud bolts, but it will result in more labor and cost increase than using stud bolts. Therefore, stud bolts are used in place of stud bars.

Fifth, the vertical fixing between the welded to the upper flange of the I-beam, as disclosed in the Republic of Korea Utility Model 20-0146601 (beam coupling structure of the deck panel) and Republic of Korea Patent 10-729860 (end structure of the triangular truss-type deck panel), Vertical rods and horizontal rods cause labor and cost increases.

The plurality of diagonal embossings in FIG. 9 may be in the form of a fin but may be in the form of a slash (//////) or a backslash. By this embossing, even if the thickness of the corrugated deck plate is thin, the bearing capacity is exerted without local buckling.

By forming the valleys 11 in an inverted diamond model, it is possible to minimize the amount of concrete poured into the valleys than the conventional rectangular valleys.
