Description

Technical Field

[0001] The invention relates to the technical field of wall panel installation, and in particular to a wall panel structure for installation on a curved wall. Background Art

[0002] Wall panels are the most common interior decoration materials in the construction industry. With the development of social economy and the advancement of science and technology, my country's interior decoration materials have achieved unprecedented rapid development. Building comfort, humanization, high environmental protection and low energy consumption have become the latest pursuit of contemporary people. This has also posed new challenges to traditional and backward building decoration companies and backward traditional materials, and brought new opportunities to new materials and environmentally friendly materials development companies. At present, the wall panels used for installation on curved walls on the market cannot adapt to the installation of a variety of walls, and the curved angles of different curved walls are different, which is not suitable for standard product development.

[0003] Chinese patent CN213477386U, with an announcement date of 2021-06-18, discloses a fiberglass wall panel suitable for curved walls, including a flexible fiberglass coil and a fiberglass base strip. The flexible fiberglass coil includes a fiberglass non-woven fabric base layer, a coating layer and a finishing layer from the inside to the outside, and the fiberglass non-woven fabric base layer is bonded to the finishing layer through the coating layer; the cross-section of the fiberglass base strip is an isosceles trapezoidal structure that is narrow on the outside and wide on the inside, and an avoidance angle is formed between the sides of two adjacent fiberglass base strips. The fiberglass non-woven fabric base layer in the flexible fiberglass coil is fixed to each fiberglass base strip through anchor nails, and the ends of the anchor nails are hidden in the coating layer, and the length of the anchor nails is less than the height of the fiberglass base strip. The prior art uses a glass fiber base strip to provide support for the flexible glass fiber coil sheet, which can bend adaptively according to the curvature of the curved wall. After the position of the glass fiber base strip is determined, the adhesive is filled in the avoidance angle to fix the glass fiber wallboard to the wall, and the construction operation is convenient. Although the flexible wave fiber coil sheet in the above patent can bend adaptively, the coil sheet is easily damaged after long-term use, and the bending angle of the coil sheet is limited, which cannot adapt to the installation of various wall surfaces.
