The thickness of galvanized floor deck is 0.8mm, 1.0mm, 1.2mm wide and 688mm ~ 940mm, and the height is 51mm ~ 76mm. The bearing plate of the engineering floor and the reinforced concrete structure work together to form a composite structure. The floor deck is laid and connected to the steel beam, the end of the deck is penetrated with the steel beam by spot welding, and the middle is used for the penetration welding of the steel beam with the peg; Spot welding of galvanized plug deck and floor bearing deck and steel beam. If it is a special-shaped cutting of the floor bearing deck with an arc area, it is cut by a plasma cutting machine, and 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, the penetration weld point is 16mm. The original design of the welding spot spacing is 305mm, and the welding spot is doubled to ensure that the floor deck is not Deformation, no slurry leakage at the end of the floor slab when the concrete is poured. When the elevation change of the floor structure is inconsistent, adopt welded steel measures to make the horizontal structure step transition. When the elevation is lowered, the I-beam web is welded with angle steel; when the elevation is elevated, the I-beam flange is welded with welded channel steel. When there are reserved openings on the floor, when the size is generally greater than 500mm × 500mm, the first opening measures are adopted, that is, the welded steel joists are added to the steel beams to separate them, increasing the rigidity of the openings, and the mesh reinforcement is disconnected at the openings, and Welding of section steel; when the size of the opening is less than 500mm × 500mm, the rear opening measures are taken, that is, the plug partition plate is added on the floor slab, the mesh reinforcement is penetrated, and the reinforcement can be cut after the concrete is cast and formed
Galvanized floor carrier board application:
Products are widely used in power plants, power equipment companies, automobile exhibition halls, steel structure workshops, cement warehouses, steel structure offices, airport terminals, train stations, stadiums, concert halls, grand theaters, large supermarkets, logistics centers, and Olympic stadium sports Stadiums and other steel structures.
Precautions for floor deck installation:
The galvanized floor deck steel structure column grid spacing is generally 5 ~ 9.0m × 8 ~ 15m, the secondary beam spacing is 3m, and the floor deck blanking length is 4.97 ~ 8.97m, transportation and installation are more difficult, especially the belt is round Vertically hoisting the floor deck in the arc area, it is more difficult to thread the jacket between the secondary beams from top to bottom, and it disrupts the normal process of secondary beam welding. The control of the cutting length is 3 ~ 6m, which can avoid the problem of inability to lift between the secondary beams during vertical transportation. A special soft sling is used when lifting the floor deck. Check the soft sling for tears or cuts each time it is lifted. Probes should be prevented when the floor deck is placed on the steel beam. When laying material, the operator should fasten the safety belt and ensure that it is fixed on the peripheral safety rope while laying. Welding adopts penetration spot welding connection. Before welding, we should prepare arc welding test and adjust welding current. Because there is no horizontal formwork and vertical support at the bottom of the floor deck, the cloth should not be too concentrated when pouring concrete. Use a flat plate vibrator in time Vibration sharing.
Application:
Galvanized metal floor decking is 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, and logistics centers , Olympic venues, stadiums and other steel structure buildings.
