摘要
为了改善桁架钢筋叠合板节点施工,提出一种新型节点构造措施。并进行了出筋叠合板、不出筋叠合板、现浇板以及新型带套筒叠合板的静力加载对比试验。试验结果表明,只要使叠合板的板端具有足够的受剪承载能力,采用套筒处理叠合板底板伸出纵向钢筋的方式对叠合板的承载能力基本无影响且叠合板具有良好的裂缝控制能力和力学性能。
In order to improve the construction of truss reinforced concrete composite slab joints, a new type of joint construction measure is proposed. The static loading comparison tests of the reinforced laminated slab, the unreinforced laminated slab, the cast-in-place slab and the new type of sleeved laminated slab were carried out. The test results show that as long as the plate end of the laminated plate has sufficient shear bearing capacity, the method of using the sleeve to treat the longitudinal reinforcement of the laminated plate bottom plate has no influence on the bearing capacity of the laminated plate and the laminated plate has good crack control ability and mechanical properties.
