Cold-formed thin-walled steel truss prefabricated laminated slab and construction method
The invention discloses a cold-formed thin-walled steel truss prefabricated laminated slab and a construction method.The cold-formed thin-walled steel truss prefabricated laminated slab comprises a cold-formed thin-walled steel truss and a concrete bottom slab, the cold-formed thin-walled steel truss is formed by bending a cold-formed thin-walled steel plate, the cross section of the cold-formed thin-walled steel plate is in an I shape, and the concrete bottom slab is arranged on the cold-formed thin-walled steel truss; comprising an upper flange, a lower flange and a web plate connecting the upper flange and the lower flange, the upper flange is filled with concrete, a cavity is formed in the lower flange, and steel bar holes are formed in the web plate; the concrete bottom plate comprises a concrete layer, transverse bottom bars and longitudinal bottom bars, the transverse bottom bars and the longitudinal bottom bars are embedded in the concrete layer and are arranged in a longitudinally and transversely interlaced mode, the transverse bottom bars are bent steel bars, the bent positions of the transverse bottom bars penetrate through the steel bar holes, and the lower flange is embedded in the concrete bottom plate. The laminated slab is higher in flexural capacity, higher in rigidity, less in concrete consumption, low-carbon and energy-saving, meanwhile, the weight of the laminated slab is reduced, the requirement for hoisting equipment is lowered, cold-formed thin-walled steel can be blanked in a customized mode, and the factory-like and intelligent degree is high.
本发明公开了一种冷弯薄壁钢桁架预制叠合板及施工方法，所述冷弯薄壁钢桁架预制叠合板包括冷弯薄壁钢桁架和混凝土底板，冷弯薄壁钢桁架由一块冷弯薄壁钢板弯折而成，横截面呈“工”形，包括上翼缘、下翼缘、连接上翼缘与下翼缘的腹板，上翼缘内填充有混凝土，下翼缘内为空腔，腹板上开有钢筋孔洞；混凝土底板包括混凝土层和埋于混凝土层内的横向底筋、纵向底筋，横向底筋、纵向底筋纵横交织排列，横向底筋为弯起钢筋，其弯起处穿过钢筋孔洞，下翼缘埋于混凝土底板内。本发明的叠合板抗弯承载力更强、刚度更高，混凝土用量更少，低碳节能，同时减轻了叠合板重量，降低对起重设备的要求，冷弯薄壁钢可定制化下料，工厂化、智能化程度高。
