Laminated slab floor system and preparation method based on prestressed floor with truss

Abstract

The invention provides a laminated slab floor system based on a pre-stress baseplate with a truss and a preparation method of the same, wherein overall performance is good, the laminated slab has strong rigidity, a joint surface has strong shear capacity, and construction is convenient. The laminated slab floor system comprises a laminated floor slab and a supporting construction component connected to the laminated floor slab, wherein the laminated floor slab comprises a pre-fabricated baseplate, the truss and a cast-in-place laminated layer, the pre-fabricated baseplate comprises horizontal structural ribs, the bottom part of the truss is embedded in the pre-fabricated baseplate, the top part of the truss is higher than the upper surface of the pre-fabricated baseplate and embedded in the cast-in-place laminated layer, the cast-in-place laminated layer is disposed on the prefabricated baseplate, and hogging moment steel ribs are disposed inside the cast-in-place laminated layer; and the laminated floor slab is located on the supporting construction component, and the supporting construction component is a load bearing wall, a cast-in-place concrete beam, a ring beam, a cast-in-place concrete shear wall, a superposed beam, a prefabricated shear wall or a steel beam.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a laminated slab floor system based on a prestressed floor with trusses and a preparation method. Background technique [0002] The industrialization of construction has become an inevitable trend in the development of my country's construction industry. It has become the mission of modern construction practitioners to transform the cast-in-place construction model into a prefabricated and assembled on-site construction model. [0003] At present, laminated slabs mainly include ordinary flat prestressed concrete laminated slabs, prefabricated ribbed prestressed concrete laminated slabs and ordinary reinforced truss laminated slabs. Ordinary flat prestressed concrete composite slabs rely on the rough surface on the upper surface of the base plate to combine with the concrete of the laminated layer, which resists section shear force and has poor shear resistance; prefabricated ri...

AI Technical Summary

Problems solved by technology

Ordinary flat prestressed concrete composite slabs rely on the rough surface on the upper surface of the base plate to combine with the concrete of the laminated layer, which resists section shear force and has poor shear resistance; prefabricated ribbed prestressed concrete composite slabs have concrete ribs, which are useful The ribs are easy to be damaged during the hoisting and transportation process, and it is not easy to pass through the steel bars; because of the ordinary steel bar truss laminated slabs, the plate stiffness is small and the required slab thickness is large because of the use of ordinary reinforced steel bars, which increases the weight of the structure, and The plate bears a small load range
