Fabricated formwork-disassembly-free prefabricated steel bar truss floor and construction method thereof
The invention discloses a fabricated formwork-disassembly-free prefabricated steel bar truss floor which comprises a formwork system and a concrete structure. The floor is characterized in that the formwork system is formed by splicing a plurality of independent formwork system units, and a steel bar truss of each disassembly-free formwork system unit is in lap joint with a structural beam. Uninterrupted first bottom layer steel bars which are consistent with the direction of steel bar frames are laid between the adjacent steel bar frames, and second bottom steel bars are laid on the upper portions of lower chord ribs in the direction of vertical steel bar frames, and intersections of the first bottom steel bars and the second bottom steel bars are bound and connected. An upper layer structural rib net is welded to the upper surfaces of the steel bar trusses of the formwork system. An overall steel structure formed by the formwork system and upper layer structural ribs is densely filled with concrete, and the fabricated formwork-disassembly-free prefabricated steel bar truss floor is formed after the concrete is solidified. The invention further discloses a construction method of the fabricated formwork-disassembly-free prefabricated steel bar truss floor. The floor has the advantages of being simple in structure, convenient to process, capable of improving construction efficiency, good in rigidity and the like.
本发明公开了一种装配式免拆模预制钢筋桁架楼板，包括模板系统和混凝土结构体；其特征在于，所述模板系统采用数个独立的模板系统单元拼接而成，每个免拆模板系统单元的钢筋桁架的搭接在结构梁上；在相邻的钢筋行架之间铺设与钢筋行架方向一致的不间断的第一底层钢筋，沿垂直钢筋行架方向在下弦筋的上方铺设有第二底层钢筋，第一底层钢筋和第二底层钢筋交叉处绑扎连接；在模板系统钢筋桁架的上表面焊接有上层结构筋网；在上述的模板系统和上层结构筋形成的整体钢结构内密实填充混凝土，混凝土凝固后形成预制钢筋桁架免拆模楼板。本发明还公开一种装配式免拆模预制钢筋桁架楼板的施工方法；本发明具有结构简单、便于加工、提高施工效率，刚性好等优点。
