Example Embodiment

[0041] Example 1

[0042] The autoclaved aerated concrete slab structure of the present embodiment, as figure 1 As shown, the autoclaved aerated concrete slabs 2 are vertically connected to each other, and the two top ends of the autoclaved aerated concrete slabs 2 are steps 10 opposite to each other, which are staggered when connected; one of the connected transverse joints is vertically fixed Floor 7; the corner formed by the floor 7 and the inner wall connected to the autoclaved aerated concrete slab 2 is fixedly connected to the beam 6 . The surface of the concrete slab is sprayed with waterproof paint, and its proportion is as follows

[0043] The waterproof coating includes an adhesive, an aqueous solution, and a desiccant, wherein the adhesive has a weight percentage of 70-80, the aqueous solution has a weight percentage of 5-15, and the desiccant has a weight percentage of 5. 10 parts of rubber powder, the particle size of which is not greater than 1 mm; adjusting th...

Example Embodiment

[0049] Example 2

[0050] The basic structure of the autoclaved aerated concrete slab structure of this embodiment is the same as that of Embodiment 1. The difference and improvement lies in that the beam 6 is an I-shaped steel beam, and the upper surface thereof is fixed with a rivet 61, which is fixed to the floor 7 by the rivet 61. connect. The floor slab 7 is tightened by the I-beam, and the floor slab 7 is close to the connecting transverse joint to avoid water seepage. The inner wall of the autoclaved aerated concrete slab 2 is also fixed with two angle steels 5 distributed up and down, and the upper angle steel 5 is attached to the connecting transverse joint formed by the two autoclaved aerated concrete slabs 2, and supported on the bottom of the floor 7, The bottom angle steel 5 is supported on the bottom of the I-beam beam. Improve the stability of I-beam fixing. The surface of the concrete slab is sprayed with waterproof paint, and its proportion is as follows

Example Embodiment

[0056] Example 3

[0057] The basic structure of the autoclaved aerated concrete slab structure of this embodiment is the same as that of the embodiment 2, the difference and improvement lies in that two angle steels 5 are fixed on the inner wall of the autoclaved aerated concrete slab 2 through two bolts 1 . To improve the fixed stability of the angle steel 5. The connection between the floor 7 and the autoclaved aerated concrete slab 2 is filled with fine stone concrete caulking 8 , and the floor 7 and the autoclaved aerated concrete slab 2 are connected together through the transition of the fine stone concrete slab 8 . The connection between the fine stone concrete caulking 8 and the autoclaved aerated concrete slab 2 is filled with an elastic material caulking 9, which acts as a buffer to avoid and reduce stress changes on the floor 7 due to environmental changes. The surface of the concrete slab is sprayed with waterproof paint, and its proportion is as follows

Abstract

The invention discloses an aerated concrete slab. The aerated concrete slab comprises autoclaved aerated concrete slabs (2) which are vertically connected with each other, and is characterized in thatthe two tops of the autoclaved aerated concrete slabs (2) are steps (10) opposite to each other, and are matched with each other in a staggered manner during connection; a floor slab (7) is vertically fixed to one connecting transverse joint; a cross beam (6) is fixedly connected to a corner formed between the floor slab (7) and the inner wall of the connected autoclaved aerated concrete slab (2); the surface of the concrete slab is sprayed with waterproof coating.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to an autoclaved aerated concrete slab structure. Background technique [0002] According to the national standard "Autoclaved Aerated Concrete Slab" GB15762-2008, autoclaved aerated concrete slab (NALC) refers to a high-performance autoclaved lightweight aerated concrete slab made of cement, lime, and sand. (Thickness ≥ 150mm) Both sides are tongue and groove boards, the width of the board is 600, and the two ends are flat. As an exterior wall panel, because the two ends are flat, there will be horizontal seams when the exterior wall panels are installed vertically or vertical seams when they are installed horizontally, and then splicing will produce through seams, although the seams are treated with PE rods, special sealants and other materials , but due to the limited service life of the sealant, deformation between layers or construction problems, water leakage ofte...
