Description

Technical Field

[0001] This utility model relates to the technical field of rigid polyurethane sandwich panels with metal surfaces, specifically a high-strength rigid polyurethane sandwich panel with metal surfaces. Background Technology

[0002] Sandwich panels consist of two layers of molded metal panels and a high-polymer thermal insulation core that is foamed and cured directly between the panels. They are easy to install, lightweight, and efficient. The filling system also uses a closed-cell molecular structure, which can prevent moisture condensation. Sandwich panels are a common product in current building materials, with excellent flame retardant, sound insulation, and environmental protection properties. Polyurethane sandwich panels are a type of sandwich panel that uses polyurethane as the filling material for the core. The material is lightweight and has good thermal insulation properties, and is often used as a wall installation structure in buildings.

[0003] Rigid polyurethane sandwich panels with metal faces are widely used in roofing and wall cladding systems for industrial plants, warehouses, and large public buildings due to their excellent thermal insulation properties, high mechanical strength, and convenient installation. However, existing rigid polyurethane sandwich panels with metal faces still have the following shortcomings in practical applications;

[0004] Polyurethane sandwich panels use polyurethane as the inner cavity filler. Although polyurethane has good thermal insulation properties, its own structural support strength is limited. The inner cavity of the sandwich panel is supported only by the polyurethane filler. Although there is external metal panel support and protection, the strength of the middle part of the sandwich panel is still relatively weak and the structural stability is poor. In addition, traditional sandwich panels are not convenient and quick to install, thus reducing the efficiency and effect of using rigid polyurethane sandwich panels with metal faces, resulting in poor practicality. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a high-strength metal-faced rigid polyurethane sandwich panel. The aim is to solve the problems of limited structural support strength of polyurethane, despite its good thermal insulation properties; the inner cavity of the sandwich panel relies solely on polyurethane filler for support; and the central strength of the sandwich panel remains weak and structural stability is poor despite the external metal panel's support and protection. Furthermore, traditional sandwich panels are not convenient or quick to install. Therefore, this invention enhances the efficiency and effectiveness of the metal-faced rigid polyurethane sandwich panel, thus improving its practicality.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-strength metal-faced rigid polyurethane sandwich panel, comprising a sandwich panel body, wherein a reinforcing mechanism is provided within the sandwich panel body; the reinforcing mechanism further comprises a polyurethane filling layer and reinforcing plates, wherein a working cavity is provided within the sandwich panel body, wherein multiple sets of reinforcing plates are provided inside the working cavity, wherein a polyurethane filling layer is provided between the reinforcing plates, and an installation mechanism is provided on the outer side of the sandwich panel body.

[0009] Furthermore, to improve the installation effect, the present invention includes the following improvements: the installation mechanism further includes an installation plate and a sliding block. A groove is provided on one side of the installation plate, an installation plate is provided on the right side of the sandwich panel body, and a sliding block is provided on the left side of the sandwich panel body. The sliding block is slidably connected to the groove in the corresponding other sandwich panel body.

[0010] Furthermore, in order to improve the stability of the reinforcing plate, the present invention is improved as follows: the reinforcing plate is inclined and the multiple sets of reinforcing plates are arranged in a V-shape within the working cavity.

[0011] Furthermore, to improve stability, the present invention includes the following improvement: the sandwich panel body is made of stainless steel metal plate.

[0012] Furthermore, in order to improve the strength of the sandwich panel body, the present invention includes: reinforcing ribs, wherein multiple sets of reinforcing ribs are evenly distributed on the inner wall of the working cavity.

[0013] Furthermore, the improvements of this utility model include: the sliding block is configured as a T-shape, and the sliding groove is adapted to the corresponding sliding block.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a high-strength metal-faced rigid polyurethane sandwich panel, which has the following beneficial effects:

[0016] Structural strength and stability are significantly improved

[0017] The working cavity is supported by a composite structure of "V-shaped reinforcing plate + inner wall reinforcing ribs": the V-shaped reinforcing plate disperses the external load and avoids stress concentration in the middle, while the reinforcing ribs enhance the buckling resistance of the inner wall and improve the overall stability; the reinforcing plate and the polyurethane filling layer form a "rigid skeleton + flexible filling" system, which takes into account both high strength and resistance to brittle fracture.

[0018] Installation efficiency has been greatly improved.

[0019] The "T-shaped sliding block + matching groove" design enables "sliding embedding" splicing, which requires no complicated procedures and can be operated by a single person. The installation efficiency is improved compared to the traditional method, and the T-shaped structure prevents splicing misalignment and ensures accuracy.

[0020] Balancing heat insulation and durability

[0021] The polyurethane filling layer is retained to maintain excellent thermal insulation; the sandwich panel body is made of stainless steel, which is corrosion-resistant and weather-resistant, and the reinforcement mechanism enhances its resistance to deformation, extending its service life to more than 15 years.
