Problems solved by technology

[0002] The existing cast-in-place slab is an integral concrete structure with a relatively large specific gravity, resulting in a relatively large building weight and high foundation costs
The specific gravity of air-entrained concrete is relatively small, but its strength is not good, so it cannot be used as a load-bearing component alone

Embodiment 1

[0021] An autoclaved aerated concrete and reinforced concrete composite structural member, which consists of: a concrete structural member 1 for building with reinforcing steel bars 5, and the low-stress part near the horizontal mandrel in the middle of the member is made of autoclaved aerated concrete 2. The specific width and shape can be determined by usual engineering calculations and the label of aerated concrete.

Embodiment 2

[0023] Among the above-mentioned autoclaved aerated concrete and reinforced concrete composite structural members, the autoclaved aerated concrete member is a columnar prefabricated member 2, and a set of positioning members 3 can be arranged on the side of the columnar as required , During the on-site construction, the position of the aerated concrete precast component in the cast-in-situ slab is ensured by the positioning piece. In the concrete member, tensile steel bars 4 may be provided as required. By increasing the bearing capacity of reinforced load-bearing parts, aerated concrete replaces ordinary concrete at non-load-bearing parts, thereby reducing the weight of non-load-bearing parts, thereby optimizing wall performance

Embodiment 3

[0025] An application of the above-mentioned composite structural member of autoclaved aerated concrete and reinforced concrete as floor slab and roof slab.

Abstract

The invention relates to a composite structure of autoclaved aerated concrete and reinforced concrete and an application thereof. The prior precast slabs have large specific gravity, resulting in high weight of buildings and very high cost of foundations. The autoclaved aerated concrete has low specific gravity but poor strength, so as not to be used as supporting parts. The inventive product comprises a building concrete structure member (1) containing reinforced steel bars, wherein the low stress part at the middle of the concrete structure member uses autoclaved aerated concrete (2). The product can be used as precast elements for buildings, such as floor slabs and roof slabs, etc.

Description

Technical field: [0001] The invention relates to a lightweight concrete building board adopting an autoclaved aerated method and its application as a floor slab and a roof slab. Background technique: [0002] The existing cast-in-place slab is a monolithic concrete structure with a relatively large specific gravity, resulting in a large building weight and high foundation cost. The specific gravity of aerated concrete is relatively small, but its strength is not good and cannot be used as a load-bearing component alone. Summary of the invention: [0003] The purpose of the present invention is to provide a lightweight and high-strength prefabricated panel, which can reduce the weight of the building and greatly reduce the construction cost. [0004] The above objectives are achieved through the following technical solutions: [0005] The autoclaved aerated concrete and reinforced concrete composite structural component includes: a concrete structural component for building with ...
