Description

Technical Field

[0001] This utility model relates to the field of exterior wall panel installation technology, and in particular to a fixing device and exterior wall device for exterior wall panels. Background Technology

[0002] To enhance the strength and insulation effect of building insulation wall panels, decorative panels (bricks) or insulation bricks (insulation boards) are typically applied to the exterior walls. Traditional brickwork, being small in size, can be adhered using adhesives. However, recently widely used green and environmentally friendly decorative materials—such as microcrystalline boards—can reach sizes of 2500mm x 1000mm. Using adhesives in these cases can easily lead to weak adhesion and detachment of the decorative panels. This delays the installation of the exterior wall panels, causing overall construction delays, reduced efficiency, and compromised construction quality, resulting in losses for the construction company.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a fixing device and an exterior wall device for exterior wall panels, so as to solve the problems existing in the prior art, ensure the stable and reliable fixing of exterior wall panels, shorten construction time, and improve construction quality.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Figures 1-2As shown, the system includes multiple crossbeams 1, multiple fixed columns 2, and multiple connectors 3. Horizontally, multiple crossbeams 1 at the same height are arranged end-to-end. Vertically, multiple crossbeams 1 are arranged at intervals. Each crossbeam 1 extends horizontally (i.e., its length is parallel to the horizontal plane). Each fixed column 2 extends vertically (i.e., its length is parallel to the vertical direction and perpendicular to the horizontal plane). The fixed columns 2 are used to fix the crossbeams 1 at right angles and are fixedly connected to at least one crossbeam 1. Each fixed column 2 includes an outer mounting plate 204, a first base plate 201, and a second base plate 202. The two ends of the outer mounting plate 204 are fixedly connected to the first base plate 201 and the second base plate 202 respectively via a web plate 203. The first base plate 204... The side of the second base plate 202 away from the outer mounting plate 204 is used for fixed connection with the crossbeam 1; the side of the outer mounting plate 204 away from the first base plate 201 and the second base plate 202 is used for contact with the outer wall panel; the outer mounting plate 204 and each web plate 203, the first base plate 201 and the corresponding web plate 203, and the second base plate 202 and the corresponding web plate 203 are all at right angles; the connector 3 has a first mounting surface and a second mounting surface that are perpendicular to each other; the first mounting surface is used for fixed connection with the web plate 203; the second mounting surface is parallel to the plane of the side of the outer mounting plate 204 away from the crossbeam 1; in the vertical direction, the upper end of the second mounting surface is used for fixed connection with the previous outer wall panel by the first fastener 4, and the lower end of the second mounting surface is used for fixed connection with the next outer wall panel by the second fastener 5.
