Description

Technical Field

[0001] This utility model relates to the field of building exterior wall panel technology, and in particular to a composite thermal insulation exterior wall panel. Background Technology

[0002] With the development of construction technology, the use of prefabricated exterior wall panels has become widespread and standardized. Prefabricated exterior wall panels are large panels pre-produced in factories with predetermined installation dimensions. They can be directly fixed to the reinforced concrete structure of a building using fasteners, replacing the original brick walls. This greatly improves construction speed while providing excellent thermal insulation and soundproofing. The main materials for exterior wall panels include rock wool boards, polyurethane boards, foamed concrete boards, steel plates, and gypsum boards. Among them, rock wool boards provide thermal insulation, polyurethane boards provide both thermal insulation and moisture protection, and foamed concrete boards, steel plates, and gypsum boards provide fire resistance and structural support.

[0003] In the prior art, the utility model patent with authorization announcement number CN218876502U provides a polyurethane rock wool composite board, which includes two polyurethane layers and a rock wool layer fixedly connected between the two polyurethane layers. Multiple rock wool fibers are arranged in the rock wool layer, and the multiple rock wool fibers are distributed vertically between the two polyurethane layers, which ultimately improves the compressive strength of the composite board and avoids unevenness on the surface of the composite board when applying a coating.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: 1. When installing existing boards, it is inconvenient to align adjacent boards, which requires manual adjustment and is time-consuming; 2. The existing boards have weak support capacity and insufficient compressive strength. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a composite thermal insulation exterior wall panel. During installation, this composite thermal insulation exterior wall panel can easily achieve alignment between adjacent panels; it has strong support capacity; the structure between the composite layers of the panel is stable; and it has a long service life.

[0006] The technical solution to the technical problem solved by this utility model is as follows: An embodiment of this utility model provides a composite thermal insulation exterior wall panel, including a rock wool board and a polyurethane board. The rock wool board is placed in the middle, and two polyurethane boards are placed on the top and bottom sides of the rock wool board, respectively. The composite thermal insulation exterior wall panel also includes a foamed concrete board, a retaining strip, and a blocking strip. Two foamed concrete boards are placed on the side of the two polyurethane boards away from the rock wool board, respectively. Vertical through slots are provided on both sides of the polyurethane board. The blocking strip corresponds to the shape and size of the slots, and the cross-section of the retaining strip is twice the cross-section of the blocking strip.

[0007] As an optimization, the cross-sectional shape of the slot is rectangular or an open trapezoid, the cross-section of the blocking strip is a corresponding rectangle or trapezoid, and the cross-section of the card strip is rectangular or hexagonal.

[0008] As an optimization, the polyurethane board is connected to the rock wool board using microporous foaming molding technology.

[0009] As an optimization, the composite thermal insulation exterior wall panel also includes fastening bolts that penetrate the rock wool board, with both ends of the fastening bolts located in the polyurethane board or concrete board on the upper and lower surfaces of the rock wool board, respectively.

[0010] As an optimization, the composite insulated exterior wall panel also includes supporting steel bars, which are vertically arranged in the polyurethane board and the concrete board, and the supporting steel bars penetrate the top and bottom surfaces of the composite insulated exterior wall panel.

[0011] As an optimization, the composite thermal insulation exterior wall panel also includes horizontal reinforcing bars, which are horizontally connected to adjacent supporting reinforcing bars.

[0012] The effects provided in the description of this utility model are merely those of the embodiments, and not all the effects of this utility model. The above technical solutions have the following advantages or beneficial effects:

[0013] 1. The retaining strip is installed in the groove between two adjacent composite insulated exterior wall panels, and the blocking strip is installed in the groove along the edge of the composite insulated exterior wall panel to seal the groove and ensure the strength of the exterior wall panel. By using retaining strips to connect two adjacent composite insulated exterior wall panels, the panels can be easily aligned during installation. The use of foamed concrete panels improves the supporting and compressive strength of the composite insulated exterior wall panel and enhances its fire resistance.

[0014] 2. By using microporous foaming molding technology to connect rock wool boards and polyurethane boards; and by using fastening screws to connect rock wool boards, polyurethane boards, and foamed concrete boards, the structure between each composite layer of the board is stable and the service life is long.

[0015] 3. By incorporating reinforcing bars into the polyurethane and concrete panels, the compressive strength of the composite insulated exterior wall panel is improved. Furthermore, the stability and positional accuracy of the reinforcing bars within the exterior wall panel are enhanced by using transverse connecting bars to connect adjacent reinforcing bars.

The blocking strip 8 corresponds to the shape and size of the retaining groove 21, and the cross-section of the retaining strip 6 is twice the cross-section of the blocking strip 8. The polyurethane board 2 is connected to the rock wool board 1 using microporous foaming molding technology. The cross-sectional shape of the retaining groove 21 is an open trapezoid, the cross-section of the blocking strip 8 is a corresponding trapezoid, and the cross-section of the retaining strip 6 is hexagonal.

[0028] The retaining strip 6 is installed in the retaining groove 21 between two adjacent composite insulated exterior wall panels, and the blocking strip 8 is installed in the retaining groove 21 on the edge of the composite insulated exterior wall panel to seal the retaining groove 21 and ensure the strength of the exterior wall panel.
