A prefabricated concrete floor system with interlocking interlocking joints and its construction method

Abstract

The invention discloses a staggered interlocking prefabricated concrete floor system, which comprises a plurality of prefabricated floor slabs with interlocking and interlocking front and back interlocking interlocking interlocking installation and use of a plurality of concave-convex grid-like tooth grooves, and the upper and lower prefabricated floor slabs pass through the interlaced concave-convex The grid-shaped tooth grooves are tightly occluded and connected, and the joints between the slabs are staggered. The slab seams between two adjacent prefabricated slabs are pasted with FRP fiber cloth and epoxy resin. The strips are connected into a whole. The present invention provides a brand-new prefabricated assembled floor plan, which is novel and reasonable in design, adopts the basic idea of ​​"one-way prefabrication, positive and negative interlocking, staggered joints, joint reinforcement", and combines "large slab prefabrication, split use "The prefabrication process uses the characteristics of the floor slab to complete the assembly construction. The cast-in-place strips at the end of the slab and the reinforcement of FRP fiber cloth at the seam of the slab can effectively improve the overall performance of the assembly floor structure and the efficiency of prefabricated construction, saving human resource costs and economic benefits. Significantly, it is beneficial to popularize and use.

Description

technical field [0001] The invention relates to the technical field of prefabricated prefabricated floor slabs, in particular to a staggered interlocking prefabricated concrete floor system and a construction method thereof. Background technique [0002] The prefabricated building refers to a building formed by producing and processing some or all of the components used in the building in the factory, and then transporting them to the construction site, where they are installed and spliced. Therefore, the prefabricated building has the following four characteristics: first, the construction speed is fast; second, it is less affected by the climate; third, it saves a lot of labor; fourth, it is green and environmentally friendly. The prefabricated structural system relies on its advantages of standardization, industrialization, industrialization, assembly, intensification, high efficiency, intelligent construction, energy saving and environmental protection. The national and ...
