A prefabricated and assembled lattice composite floor slab and its construction method

Abstract

The invention discloses a prefabricated and assembled lattice type composite floor slab and a construction method thereof, belonging to the technical field of prefabricated and assembled buildings. The prefabricated assembled lattice type composite floor is assembled by a plurality of prefabricated slab units. Intercostal grid; the sides of the rib beams that constitute the intercostal grid are provided with upper, middle, and lower planes, and the lower parts of the upper and lower planes extend toward the intercostal grid to form inclined surfaces. The surface is connected with the surface of the upper and lower regions, and the intercostal cells are correspondingly filled with intercostal cell filling materials. Adopting the technical scheme of the present invention can effectively satisfy its heat insulation and sound insulation performance on the basis of ensuring the bearing capacity of the floor slab, and at the same time can better control the thickness of the floor slab. Continuous performance improvement conditions, strong practicability.

Description

technical field [0001] The invention belongs to the technical field of prefabricated and assembled buildings, and more specifically relates to a prefabricated and assembled lattice-type composite floor slab and a construction method thereof. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and then transported to the construction site. A building that is assembled and installed on site through reliable connections. The advantages of prefabricated buildings are: high efficiency, compared with traditional methods, factory production is not affected by natural environments such as bad weather, the construction period is more controllable, and the production efficiency is much higher than manual work; high pr...

Problems solved by technology

[0007] The purpose of the present invention is to solve the current lack of prefabricated assembled structural sound insulation floor products that are convenient for construction. Commonly used prefabricated assembled floor slabs are generally prefabricated slabs with steel trusses + cast-in-place layers, and their thickness cannot meet the current green building standards. Sound insulation requirements; and the common hollow floor is poured integrally, and the slab and rib beam are stressed together. When prefabricated construction is applied, not only the construction is difficult, but also the sound wave is transmitted through the rib beam, and the sound insulation effect is not good. , providing a prefabricated assembled lattice composite floor and its construction method
