The invention discloses a concrete composite slab base plate based on a corrugated steel web truss and a cement base plate. The concrete composite slab base plate based on the corrugated steel web truss and the cement base plate includes a cement base plate and a plurality of corrugated steel web trusses; the corrugated steel web trusses are arranged in parallel and spaced along the main span direction of the cement base plate, and the spacing between two adjacent corrugated steel web trusses is 300mm to 1000mm; the web of each corrugated steel web truss adopts a rolled cold-formed corrugatedsteel web, and the width of the corrugated steel web is 50mm to 300mm; the upper chord limbs of the corrugated steel web truss are made of cold-formed thin-walled steel, and the upper chord limbs arefilled with mortar or fine stone concrete; the upper chord limbs are fixedly connected to the wave crest surface of the corrugated steel web; the trough plate surface of the corrugated steel web is embedded in the cement base plate and is fixedly connected to the cement base plate through connecting pieces; and the embedding depth is not greater than the half wave height of the corrugated steel web. The concrete composite slab prepared by the invention has high rigidity, high bearing capacity, is convenient for transportation and hoisting, and has a low construction cost.
本发明公开了一种基于波纹钢腹板桁架和水泥基板的混凝土叠合板底板，包括水泥基板和若干波纹钢腹板桁架，波纹钢腹板桁架沿水泥基板的主跨度方向平行间隔布置，相邻两个波纹钢腹板桁架间的间距为300mm～1000mm，波纹钢腹板桁架的腹板采用辊压冷弯成型波纹钢腹板，波纹钢腹板的宽度为50mm～300mm，波纹钢腹板桁架的上弦肢件采用冷弯薄壁型钢，上弦肢件内填充砂浆或细石混凝土，上弦肢件与波纹钢腹板的波峰板面固定连接，波纹钢腹板的波谷板面埋置在水泥基板内且通过连接件与水泥基板固定连接，埋置深度不大于波纹钢腹板的半波高。本发明制备的混凝土叠合板底板刚度大、承载力高，方便运输和吊装，建造成本低。
