Agglomeration building variable cross-section one-way precast hollow slab overlapped floor system
The invention provides an agglomeration building variable cross-section one-way precast hollow slab overlapped floor system. Overlapped layers are fixedly connected between every two adjacent variablecross-section one-way precast hollow slabs in the length direction of the overlapped floor system. The variable cross-section one-way precast hollow slabs comprise midspan areas and support areas. The support areas are located on the two sides of the corresponding midspan areas at equal intervals. The thicknesses of the midspan areas are larger than those of the support areas. The overlapped layers are poured at the opposite support areas of every two adjacent variable cross-section one-way precast hollow slabs. The upper surfaces of the overlapped layers are flush with those of the midspan areas. The problems that the using quantity of cast-in-place concrete overlapped layers is large, bearings need to be arranged at the construction period and connection between slabs and walls and connection between the walls are unreasonable in an overlapped floor system of the prior art are solved. According to the agglomeration building variable cross-section one-way precast hollow slab overlapped floor system, there is no need to arrange slab bottom bearings at the construction stage of the overlapped floor system, continuous stressing of floor slabs can be achieved after negative moment reinforcement is arranged inside each overlapped layer and overlapped layer concrete is poured, and it is ensured that the effects that the using amount of cast-in-place concrete is reduced and construction efficiency.
本发明提出一种集块建筑变截面单向预制空心板叠合楼盖，该叠合楼盖在长度方向上，相邻两块变截面单向预制空心板间固定连接有叠合层，变截面单向预制空心板包块跨中区域和支座区域，支座区域等距地位于跨中区域的两侧，跨中区域的厚度大于支座区域的厚度，相邻两块变截面单向预制空心板的相对支座区域上浇筑有叠合层，叠合层的上表面与跨中区域的上表面齐平。解决了现有技术的叠合楼盖存在现浇混凝土叠合层用量大、施工期间需要设置支承、板与墙连接及墙与墙连接不够合理的问题，本发明使得该叠合楼盖施工阶段免设板底支承，设置叠合层内负弯矩筋并浇筑叠合层混凝土后能实现楼板的连续受力，确保节省现浇混凝土用量，提高施工效率。
