Abstract

The invention discloses a prestressed concrete two-way laminated slab and a manufacturing method thereof, which belong to the technical field of construction engineering. Its structure includes a prefabricated bottom plate, a laminated layer and a steel truss. The trusses are connected, and the laminated layer transverse steel bars and laminated layer longitudinal steel bars are arranged inside the laminated layer. The laminated layer longitudinal steel bars are fixed on the upper surface of the steel truss. The transverse prestressed reinforcement is arranged at equal intervals, the longitudinal prestressed reinforcement is arranged at equal intervals along the length direction, the longitudinal prestressed reinforcement is located above the transverse prestressed reinforcement, and multiple steel trusses are arranged at equal intervals along the width direction on the upper part of the prefabricated floor. The invention also discloses a manufacturing method of the laminated board. The invention has the characteristics of high overall rigidity of the laminated slab, good force bearing performance, two-way force transmission mechanism, no joints on the prefabricated bottom plate, reduced on-site support and formwork consumption, and improved construction speed and the like.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prestressed concrete two-way laminated slab and a manufacturing method thereof. Background technique [0002] Prefabricated buildings have the advantages of high industrialization level, fast construction speed, reduced material and energy consumption, and reduced dust and construction waste on the construction site. In recent years, with the improvement of my country's requirements for green construction, energy conservation and emission reduction, and the substantial increase in labor market prices, prefabricated concrete structures have been widely promoted and applied in various provinces across the country. Floor slabs began to change from traditional integral cast-in-place or integral prefabrication to laminated floor slabs with factory prefabricated lower floors and cast-in-place upper laminated floors. [0003] Compared with the traditional integral ca...
