Q345 0.8-1.5mm Corrugated Metal Floor Decking High Bearing Capacity

Product Specification

Customized Metal Floor Decking High Bearing Capacity for Floor Slab

The pressed steel plate that supports the floor concrete is called the pressed steel plate, that is, the metal floor decking.

Specifications:

The floor deck profile has a thickness of 0.8mm, 1.0mm, 1.2mm, a width of 688mm~940mm, and a height of 51mm~76mm. The floor deck of the engineering floor and the reinforced concrete structure work together to form a composite structure. The floor deck is laid and connected with the steel beam, the end of the slab is penetrated and spot welded with the steel beam, and the stud and the steel beam are penetrated and welded in the middle; the floor deck is connected with the pressure hole with special clamping pliers; the plug is dedicated Spot welding of galvanized plug plate and floor deck and steel beam. If it is a special-shaped cutting of the floor deck with a curved area, the plasma cutting machine is used to cut the cut, the cut is smooth and the surface galvanized layer is complete. The floor deck is welded by manual arc spot welding, the electrode is E4303, the diameter is 3.2mm, and the penetration welding point is 16mm. The original design welding spot spacing is 305mm, and the welding point will be doubled to ensure that the floor deck is not when the operator walks. Deformation, the end of the floor bearing slab does not leak when the concrete is poured. When the elevation of the floor structure changes inconsistently, the measures of adding welded steel shall be adopted to make the horizontal structure a step transition. When the elevation is lowered, welded angle steel is added to the web of the I-beam; when the elevation is raised, welded channel steel is added to the flange of the I-beam. When there is a reserved opening on the floor, when the size is generally greater than 500mm×500mm, the first opening measure is adopted, that is, the welded steel joist is added to the steel beam to increase the rigidity of the opening. The mesh reinforcement is disconnected at the opening and is connected to the Welding of profiled steel; when the size of the opening is less than 500mm×500mm, the measures of opening the hole will be adopted, that is, adding a plug dividing plate on the floor deck, the mesh steel bar is penetrated, and the steel bar can be cut after the concrete is poured.

Features:

1: Meet the requirements of rapid construction of the main steel structure, can provide a firm working platform in a short time, and can use multiple floors to lay profiled steel plates and layered concrete slabs.

2: In the use stage, the floor deck is used as the tensile steel bar of the concrete floor slab, which also improves the rigidity of the floor slab and saves the amount of steel and concrete.

3: The surface embossing of the profiled slab produces the greatest bonding force between the floor deck and the concrete, so that the two form a whole, with stiffening ribs, so that the floor deck system has a high-strength bearing capacity.

4: Under the cantilever condition, the floor deck is only used as a permanent template. The length of the cantilever can be determined according to the cross-sectional characteristics of the floor deck. In order to prevent the cracking of the cantilevered slab, it is necessary to equip the support with negative ribs according to the design of the structural engineer.

The length of the cantilever can be determined according to the cross-sectional characteristics of the floor deck. In order to prevent the cracking of the overhanging plate, it is necessary to equip the support with negative ribs according to the design of the structural engineer.

Application:

Products are widely used in power plants, power equipment companies, automobile exhibition halls, steel structure workshops, cement warehouses, steel structure offices, airport terminals, railway stations, stadiums, concert halls, grand theaters, large supermarkets, logistics centers, Olympic venues, sports Steel structure buildings such as stadiums.

To meet the requirements of rapid construction of the main steel structure, it can provide a firm working platform in a short time, and can use multiple floors to lay profiled steel plates and layered concrete slabs.
