Description

Technical Field

[0001] The utility model relates to the technical field of wall insulation, in particular to a composite insulation board. Background Art

[0002] As is known, composite insulation wall panels are currently widely used building materials products. As an important component of the wall, the strength, impact resistance, and thermal insulation performance of the wall panels have become important factors affecting the development of building exterior walls. The composite insulation wall panels in the existing technology often adopt a multi-layer structure consisting of an insulation layer, a waterproof layer, and a heat insulation layer, and these layers are usually installed by pasting. Due to the poor seismic performance of the composite insulation board, when affected by changes in the external environment or when the wall vibrates strongly, the layers are easy to fall off, thereby affecting the thermal insulation performance of the insulation board. In addition, the existing composite insulation wall panels are mostly placed for installation during the installation process. This installation method will result in poor connection between two adjacent insulation wall panels, and gaps are easily generated at the joints, affecting the thermal insulation effect. Summary of the Invention

[0003] In order to overcome the deficiencies in the background technology, the utility model discloses a composite thermal insulation board.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

Corresponding to the first step at the recessed surface, a plurality of recessed holes are evenly spaced between the left side below the thermal insulation layer A and the step surface, and springs are fixed in the recessed holes. The thermal insulation layer and the sound insulation layer are both located between the convex strips and the inner wall of the recessed surface. A plurality of convex columns that slide with the recessed holes are provided on the upper surface of the thermal insulation layer, and a plurality of sliding strips provided on the lower surface of the thermal insulation layer are respectively slidably connected with a plurality of sliding grooves on the upper surface of the sound insulation layer. A recessed step surface is provided on the upper right side of the thermal insulation layer B, and cooperates with the second step on the inner wall of the recessed surface of the outer frame.

[0006] The composite thermal insulation board has convex strips and concave surfaces arranged correspondingly on the left and right sides, and when the two outer frame bodies are connected, the concave surface of the left outer frame body is clamped with the convex strip located on the right outer frame body.

[0007] In the composite thermal insulation board, the height of the spring in an uncompressed state is two-thirds of the height of the concave hole, and the diameter of the spring is smaller than the diameter of the convex column.

[0008] In the composite thermal insulation board, a buffer gap is provided between the lower side of the thermal insulation layer A and the upper side of the heat insulating layer.

[0009] The composite insulation board is provided with jacks on the front and rear surfaces of the insulation layer B, and the side panels on the front and rear surfaces of the outer frame are provided with plug-in blocks. The side panels are plugged into the jacks through the plug-in blocks, and the outer surfaces of the side panels after plugging are flush with the front and rear rear surfaces of the outer frame.

[0010] The composite insulation board has an inwardly extending bent plate at the upper ends of the arms on both sides of the outer frame, and the cover plate is in a "convex" shape.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] The composite thermal insulation board described in the present invention has a thermal insulation layer A with a buffering function arranged in the outer frame. When it is affected by changes in the external environment or when the wall vibrates strongly, the spring achieves a buffering effect, and the thermal insulation layer A is limited by the cover plate, the heat insulation layer and the sound insulation layer are connected by a sliding bar, and the thermal insulation layer B is limited by the second step. The coordinated combination of the layers not only ensures the stability and sealing of the thermal insulation layer, but also eliminates the disadvantages of using adhesives.
