什么是钢筋桁架彩钢楼承板

为了解决第一代和第二代钢桁架楼承板净高较小等缺点,工程师研制了第三代钢筋桁架彩钢楼承板钢筋桁架彩钢楼承板第三代地板支撑板是改变和减少原有地板支撑板的凸型和高压型, 钢筋桁架彩钢楼承板将地板中的钢筋在工厂用半自动钣金焊接设备加工成钢筋桁架,以取代地板承载的凸高和支承板能力。厂内钢桁架与楼承板焊接后采用硅烷、纯锰磷化、水洗、烘干、镀锌等除锈防锈环保技术,采用高频电阻焊连接。模板系统将混凝土楼板中的钢筋与施工模板相结合,形成一个能承受施工阶段湿混凝土自重和施工荷载的承重构件,该构件在施工阶段可作为钢梁的侧向支撑。在使用阶段,钢桁架与混凝土共同承担使用荷载。

1桁架楼盖受力模式和组合方式合理,钢筋桁架彩钢楼承板现浇混凝土整体刚性好,便于双向板的施工和使用。但普通压型钢板下蒙皮与肋方向垂直,钢筋无法定位。
2施工中,当梁间距大于3米时,普通压型板基本上需要加临时支撑;钢桁架模板最大无支撑间距可达5米。
三。桁架模板上的临时开孔不需要加固,机器电线和管道的铺设方便
4钢板不参与受力,不需要防火防腐涂料,也不需要担心火灾后的修复问题。安全经济,板底平整,净高有保证,楼板双向刚度一致,抗震性能好。解决了封闭板的双向配筋问题,保证了钢筋间距和混凝土保护层厚度
5双向板的设计和施工简单方便。适用于大跨度厂房。涂层合理,螺柱焊接质量可靠,端部无需熔透焊接。地板的抗剪性能良好。
6硅烷化、磷化、水洗干燥、镀锌等除锈防锈工艺,密封避光。

In order to solve the shortcomings of the first generation and the second generation of steel truss floor support plates, such as the smaller net height of buildings, engineers developed the third generation of steel truss steel bearing plates. The third generation of floor support plates is to change and reduce the convex and high-pressure type of the original floor support plates, and the steel bars in the floor are processed into steel bars trusses by semi-automatic sheet metal welding equipment in the factory, so as to replace the convex height and bearing plate of the floor Carrying capacity. After welding, silane, pure manganese phosphating, water washing, drying, galvanizing and other rust removal and anti rust environmental protection technologies are used to connect the steel truss and floor support plate in the factory with high frequency resistance welding. The formwork system combines the reinforcement in the concrete floor slab with the construction formwork to form a load-bearing component which can bear the dead weight of wet concrete and construction load in the construction stage, and the component can be used as the lateral support of steel beam in the construction stage. In the use stage, the steel truss and concrete work together to bear the service load.

1. The stress mode and combination mode of the truss floor are reasonable, and the cast-in-place concrete is rigid as a whole, so the construction and use of the two-way slab can be easily completed. However, the lower skin of the ordinary profiled slab is perpendicular to the direction of the rib, and the reinforcement cannot be located.
2. In the construction, when the beam spacing is more than 3 meters, the ordinary profiled slab basically needs to add temporary support; the maximum unsupported spacing of steel truss formwork can reach 5 meters.
3. The temporary opening on the truss formwork does not need reinforcement, and the laying of machine wires and pipes is convenient
4. The steel plate does not participate in the stress, does not need fire-resistant and anti-corrosion coating, and does not need to worry about the repair problems after the fire. It is safe and economical, the bottom of the slab is flat, the clear height is guaranteed, the two-way stiffness of the floor is consistent, and the anti-seismic performance is good. The two-way reinforcement problem of the closed plate is solved, and the spacing of reinforcement and the thickness of concrete protective layer are guaranteed
5. The esign and construction of the two-way slab is simple and convenient. It is suitable for large-span workshop. The coating is reasonable, the stud welding quality is reliable, and the end does not need penetration welding. The shear performance of the floor is good.
6. Silane, phosphating, water washing and drying, zinc plating and other rust removal and rust prevention processes, sealed and protected from light.
