Description
Technical Field
[0001] The utility model relates to the field of autoclaved aerated concrete materials, in particular to a high-strength autoclaved aerated concrete compression plate. Background Art
[0002] Autoclaved aerated concrete is a lightweight prefabricated foam concrete building material that can be made into prefabricated products such as blocks, wall panels and roof panels. It has light weight and low transportation costs. The prefabricated products can be transported to the construction site for assembly, which helps shorten the construction period.
[0003] Autoclaved aerated concrete is usually made by mixing quartz sand, calcined calcium sulfate, lime, cement, water and aluminum powder, and then heating and pressurizing in an autoclave to solidify and form, with high production efficiency. In order to improve the thermal insulation effect of autoclaved aerated concrete panels, it is usually necessary to increase the porosity and reduce the density, but the compressive strength will also decrease, which needs to be improved. Utility Model Content
[0004] The utility model aims to provide a high-strength autoclaved aerated concrete compression plate to improve the structural strength, especially the compression resistance.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] Wherein, the tops of the first inclined steel mesh and the second inclined steel mesh are welded and fixed to the first flat steel mesh.
[0008] The bottoms of the first inclined steel mesh and the second inclined steel mesh are welded and fixed to the second flat steel mesh.

[0010] Wherein, the elastic buffer pad is a flame retardant rubber pad.
[0011] Wherein, the bottom surface of the elastic buffer pad is provided with flame retardant glue.
[0012] The beneficial effects of the utility model are as follows: a high-strength autoclaved aerated concrete compression-resistant plate, in which a first plane steel mesh, a second plane steel mesh and a support frame are specially designed. The first plane steel mesh and the second plane steel mesh are used to improve the compression resistance of the surface of the autoclaved aerated concrete plate substrate. When the surface is subjected to force, the force is dispersed and it is not easy to be damaged. A continuous triangular support structure is formed through the support frame to improve the structural strength inside the autoclaved aerated concrete plate substrate. Without reducing the porosity, the overall structural strength can be improved, and the thermal insulation effect is good and the compressive strength is high. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0014] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.
[0015] like Figure 1 The high-strength autoclaved aerated concrete compression plate shown in the figure comprises: an autoclaved aerated concrete plate substrate 1, a first plane steel mesh 2, a second plane steel mesh 3 and a support frame 4. The autoclaved aerated concrete plate substrate 1 is made by mixing quartz sand, calcined calcium sulfate, lime, cement, water and aluminum powder, and then heating and pressurizing and curing in an autoclave. In order to improve the thermal insulation effect, a higher porosity is required. For example, the density of the autoclaved aerated concrete plate substrate 1 is 500kg / m 3 It can ensure good thermal insulation effect, but the compressive strength is only 3.5MP, which needs to be improved.
[0016] In this embodiment, the first planar steel mesh 2, the second planar steel mesh 3 and the support frame 4 are pre-buried in the autoclaved aerated concrete slab matrix 1, and the structural strength of the autoclaved aerated concrete slab matrix 1 is improved by the first planar steel mesh 2, the second planar steel mesh 3 and the support frame 4.
[0017] The first planar steel mesh 2 is horizontally arranged above the second planar steel mesh 3, such as Figure 1 As shown, the first plane steel mesh 2 is close to the top surface of the autoclaved aerated concrete board substrate 1, and the second plane steel mesh 3 is close to the bottom surface of the autoclaved aerated concrete board substrate 1. The first plane steel mesh 2 and the second plane steel mesh 3 are used to improve the compressive resistance of the surface of the autoclaved aerated concrete board substrate 1. When the surface is subjected to force, the force is dispersed through the first plane steel mesh 2 and the second plane steel mesh 3, and it is not easy to be damaged.
[0018] In order to further improve the structural strength inside the autoclaved aerated concrete board substrate 1, the support frame 4 is distributed between the first plane steel mesh 2 and the second plane steel mesh 3 along the length direction of the autoclaved aerated concrete board substrate 1. In this embodiment, the support frame 4 includes a first inclined steel mesh 41 and a second inclined steel mesh 42, respectively. The first inclined steel mesh 41 and the second inclined steel mesh 42 are V-shaped and arranged between the first plane steel mesh 41 and the second plane steel mesh 42. The V-shaped first inclined steel mesh 41 and the second inclined steel mesh 42 cooperate with the first plane steel mesh 2 and the second plane steel mesh 3 to form a continuous triangular support structure, which can improve the overall structural strength, especially the compressive strength, without reducing the porosity.
[0019] In this embodiment, the tops of the first inclined steel mesh 41 and the second inclined steel mesh 42 are welded and fixed to the first planar steel mesh 2, and the bottoms of the first inclined steel mesh 41 and the second inclined steel mesh 42 are welded and fixed to the second planar steel mesh 3, so as to form a three-dimensional reinforcement structure with high stability, convenient production and not easy to loosen.
[0020] In order to buffer the impact, an elastic buffer pad 6 is arranged above the autoclaved aerated concrete board substrate 1. In this embodiment, the elastic buffer pad 6 is a flame-retardant rubber pad, which elastically deforms when subjected to force to reduce the impact on the autoclaved aerated concrete board substrate 1. The bottom surface of the elastic buffer pad 6 is provided with a flame-retardant adhesive 5 to bond and fix the elastic buffer pad 6 and improve the flame-retardant effect.
