Fabricated prefabricated one-way floor slab, floor slab mold and demolding manufacturing method
The invention discloses an assembly type prefabricated one-way floor slab, a floor slab mold and a demolding manufacturing method and belongs to the technical field of civil engineering. The problems that the cast-in-place amount of concrete of an existing floor slab laminated layer is large, more supports are needed in the construction and assembly period of the floor slab, and the earthquake resistance of a prefabricated slab is poor are solved. A plurality of longitudinal reinforcing steel bars are evenly distributed in the plate body in the longitudinal direction, a plurality of transverse reinforcing steel bars are evenly distributed in the plate body in the transverse direction, the angle between each longitudinal reinforcing steel bar and each transverse reinforcing steel bar is 90 degrees, variable cross sections are symmetrically arranged on the plate body, reinforcing stirrups are arranged on the variable cross sections, and a plurality of plate end teeth are arranged at the end of the variable cross section on each side. A plurality of hogging moment steel bar connecting grooves are symmetrically formed in the plate body, and a plurality of plate side connecting reinforcing grooves are symmetrically formed in the two sides of the plate body. The workload of on-site cast-in-place concrete is reduced, the cost and environmental pollution are reduced, the plate body is simple in structure and clear in force transmission, and the safety can be guaranteed.
装配式预制单向楼板、楼板模具及脱模制造方法，属于土木工程技术领域。本发明解决了目前楼板叠合层的混凝土现浇量大，楼板在施工装配期间需要较多的支承，预制板的抗震性较差的问题。本发明包括板主体，板主体内纵向均布有多根纵向钢筋，板主体内横向均布有多根横向钢筋，每根纵向钢筋与每根横向钢筋所呈角度为90°，板主体上对称设置有变截面，变截面上设置有加强箍筋，每侧变截面的端部设置有多个板端齿，板主体上对称设置有多条负弯矩钢筋连接槽，板主体的两侧对称设置有多个板侧连接加强槽。本发明减小现场现浇混凝土的工作量，降低成本以及环境污染，板主体构造简单，传力明确，安全性可以得到保证。
