Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an autoclaved aerated concrete composite insulation wall panel. Background Technology

[0002] Autoclaved aerated concrete (AAC) wall panels are porous concrete products made primarily from silica sand, cement, and lime, reinforced with rust-proofed steel bars, and cured under high temperature, high pressure, and steam. They offer excellent sound insulation and absorption properties, as well as good thermal insulation. With a lightweight specific gravity of 0.5, which is only 1 / 4 that of ordinary concrete, they significantly reduce the self-weight of the walls and lower the cost of building foundations. Products include exterior wall panels, interior wall panels, floor slabs, and roof panels.

[0003] Existing traditional external insulation adhesive boards have low strength, and while some three-layer sandwich composite wall panels have good strength, the inner and outer layers cannot work together to bear the load, resulting in low overall load-bearing capacity. Furthermore, some composite wall panels also suffer from weak compressive strength in the insulation area, making them prone to collapse. Therefore, this utility model proposes an autoclaved aerated concrete composite insulation wall panel. Utility Model Content

[0006] The autoclaved aerated concrete board and the insulation board are bonded and fixed together by an adhesive. The insulation board has an embedded insulation support pad inside. The insulation board is covered with the insulation slurry on its outer layer. The outer layer of the insulation slurry is shaped and fixed by a mesh cloth.

[0007] It also includes connectors and tie members, one end of which is fixed through the autoclaved aerated sand plate and the other end is embedded in the thermal insulation mortar or fixed to the outside of the mesh cloth.

[0008] Preferably, the autoclaved aerated sand plate is provided with a groove for fixing the connector and the tie member.

[0009] Preferably, both the connector and the tie member are equipped with rubber sealing rings.

[0010] Preferably, the thermal insulation support pad has compressive support capacity; the interior of the thermal insulation support pad is filled with thermal insulation grout.

[0011] Preferably, the adhesive is an adhesive mortar or a polyurethane adhesive.

[0012] Preferably, the insulation board is an XPS board, EPS board, phenolic board, polyurethane board, or PIR board.

[0013] Preferably, the insulating mortar is a fireproof and heat-insulating mortar.

[0014] Preferably, the connector is made of stainless steel, Q235B or FRP; the tie is made of stainless steel, Q235B, FRP or extended insulation nail.

[0015] Preferably, the connectors are located at both ends of the wall panel, and there are multiple tie members located in the middle of the wall panel.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model of autoclaved aerated concrete composite insulation wall panel adopts a design that combines autoclaved aerated concrete board, insulation board, insulation mortar and mesh cloth, which can not only ensure the wall panel's firmness, but also achieve the effect of integrated insulation and structure, with high overall load-bearing capacity and strong compressive strength.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] As shown in the attached figure, an autoclaved aerated concrete composite insulation wall panel includes an autoclaved aerated concrete board 1, an insulation board 2, an insulation mortar 3, a mortar 11, and a mesh fabric 4.

The insulation board 2 has an embedded insulation support pad 6 inside, which has compressive support capacity and can be filled with insulation mortar to ensure that the insulation area does not collapse and the structure is stable. The outer layer of the insulation board 2 is provided with insulation mortar 3, which is shaped and fixed by a mesh cloth 4. The mesh cloth 4 is an alkali-resistant mesh cloth.

[0031] It also includes connectors 7 and tie members 8, with connectors 7 passing through and fixed to both ends of the autoclaved aerated concrete plate 1; such as Figure 1As shown, one end of the tie member 8 is fixed through the autoclaved aerated concrete plate 1, and the other end is embedded in the thermal insulation mortar 3; as Figure 6 As shown, one end of the tie member 8 is fixed through and to the autoclaved aerated concrete plate 1, and the other end is fixed to the outside of the mesh cloth 4. Both the connector 7 and the tie member 8 are equipped with rubber sealing rings 10, which makes the connection hole more sealed and prevents water leakage and air leakage.
