Concrete laminated slab prefabricated part with two-way ribs

Abstract

A concrete laminated slab prefabricated component with two-way ribs relates to the field of concrete prefabricated parts technology and prefabricated structures in the construction industry. The thin plate (1) is made of a group of horizontally stressed steel bars (4) and a group of vertically stressed steel bars (5) bound together and then poured concrete, and the two sets of reinforcing ribs (2) are respectively arranged on the thin plate (1) in two directions perpendicular to each other, and the set of suspension rings (3) are respectively fixedly installed on the two sets of reinforcing ribs (2). Two-way ribs increase the stiffness of the component, reduce the deformation of the prefabricated component and the stress of the steel bar during construction; it is convenient to ensure the thickness of the protective layer for laying the steel bar on the slab; the thin concrete slab reduces the weight of the prefabricated component, which is conducive to the transportation and hoisting of the component; Tensile steel bars can be prestressed steel bars, which can save a lot of steel.

Description

technical field [0001] The invention relates to the field of concrete prefabricated parts technology and assembled structures in the construction industry, in particular to a prefabricated component of concrete laminated slabs with two-way ribs. Background technique [0002] With the development of my country's economy, the labor cost of construction is getting higher and higher. The current labor cost has gradually been higher than the price of building materials, and this trend is getting bigger and bigger. Traditional concrete structure construction is not only time-consuming, labor-intensive, but also relatively rough. If the assembled structure is completely adopted, the seismic performance is not as good as that of the cast-in-place overall structure. Therefore, the country has also proposed the green construction concept of assembling the overall structure. The existing laminated slabs use 500-600 small prefabricated components, and then lay vertically distributed ...

AI Technical Summary

Problems solved by technology

The existing laminated slabs use 500-600 small prefabricated components, and then lay vertically distributed steel bars on the prefabricated class. Due to the large difference in the thickness of the protective layer and the large difference in the two-way stiffness, the actual force is still a one-way floor. Cracks are also prone to appear at the joints of prefabricated components, and the on-site construction process is more complicated

However, for traditional cast-in-place concrete slabs, on-site construction needs to bind steel bars, support formwork and supports, and the construction process is complicated, which will waste a lot of labor
