Technical Field

[0001] This utility model relates to the field of building materials technology, and is a polyurethane insulation board that is easy to connect. Background Technology

[0002] With the continuous improvement of building energy efficiency standards, polyurethane insulation materials are widely used in building exterior wall insulation systems due to their excellent thermal insulation performance. However, existing polyurethane insulation boards suffer from problems during installation, such as inaccurate positioning, large gaps in the joints, and poor sealing, resulting in poor insulation performance and low installation efficiency. Furthermore, traditional insulation boards are mostly fixed to the wall using adhesive or mechanical methods, which not only increases the difficulty of construction but also makes subsequent maintenance and replacement difficult. Therefore, designing a polyurethane insulation board that can solve the above problems is of significant practical importance. Summary of the Invention

[0005] A polyurethane insulation board for easy connection includes an insulation board, a guide strip on one side of the insulation board with multiple inserts fixedly connected to the guide strip, a guide groove on the other side of the insulation board with slots inside the guide groove, reinforcing ribs embedded inside the insulation board, two insulation boards being connected by an interlocking method to form a joint, an elastic sealing strip being provided at the joint between the insulation boards, positioning holes being provided at the four corners of the insulation board with fasteners inside the positioning holes, and connectors being provided at the top and bottom of the insulation board.

[0006] In a preferred embodiment, the connector is provided with multiple threaded holes, and a fixing screw is threaded into each threaded hole. A washer is provided between the connector and the fixing screw.

[0007] In a preferred embodiment, the insulation board includes a main layer, a sound insulation layer fixedly connected to the upper part of the main layer, a heat insulation layer fixedly connected to the lower part of the main layer, and a protective plate fixedly connected to the outside of the heat insulation layer and the sound insulation layer, wherein the protective plate is provided with anti-slip texture.

[0008] In a preferred embodiment, the protective plate is an aluminum-zinc coated steel plate.

[0009] In a preferred embodiment, the insulation board has multiple connecting grooves on its upper and lower sides.

[0010] In a preferred embodiment, the two sides of the main body layer are fixedly bonded to the sound insulation layer and the heat insulation layer using polyurethane adhesive.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Improved Installation Efficiency: The polyurethane insulation board utilizes a slot and insert design to enable quick connection between insulation boards, simplifying installation steps and reducing construction time and costs. Simultaneously, the use of guide grooves and guide strips ensures precise alignment between insulation boards, avoiding the tedious process of manual measurement and adjustment.

[0013] 2. Enhanced Sealing Performance: The sealing strip between the two insulation boards is made of flexible rubber, which effectively fills the tiny gaps between the insulation boards, preventing the formation of thermal bridges and improving the overall sealing and insulation effect of the insulation system. Furthermore, the elastic design of the sealing strip can adapt to certain temperature changes, ensuring a tight seal during long-term use.

[0014] 3. Improved structural stability: The insulation board is embedded with reinforcing ribs, which enhances the overall strength and rigidity of the insulation board, making it less prone to deformation when subjected to external impacts and extending the service life of the insulation board.

[0015] 4. Enhanced structural stability: The use of connectors, fixing screws, and washers ensures a firm connection between insulation boards, improves the overall structural stability and durability, and reduces deformation or damage caused by environmental factors.

[0016] 5. Multifunctional integration: By integrating a heat insulation layer, a sound insulation layer, and a board into the insulation board, not only is the thermal insulation performance improved, but fireproofing and sound insulation functions are also added, making the insulation board suitable for a variety of complex environments and meeting higher building standards.

[0017] 6. Aesthetics: The anti-slip textured design on the surface protective layer not only enhances the aesthetics of the insulation board but also increases its safety when used on the ground, making it suitable for various building application scenarios.

[0018] In summary, this system enables rapid connection between insulation boards, simplifying installation steps and reducing construction time and costs. The combined use of guide grooves and guide strips ensures precise alignment between insulation boards, avoiding the tedious process of manual measurement and adjustment. Simultaneously, the flexible rubber sealing strip effectively fills tiny gaps between insulation boards, preventing the formation of thermal bridges, improving overall sealing and insulation performance. Its elastic design also adapts to temperature changes, ensuring sealing performance over long-term use. Embedded reinforcing ribs enhance the overall strength and rigidity of the insulation boards, making them less prone to deformation under external impact and extending their service life. The use of connectors, fixing screws, and gaskets ensures a secure connection between insulation boards, improving the stability and durability of the overall structure. By integrating a thermal insulation layer, a sound insulation layer, and a protective panel, this insulation board not only improves thermal insulation and protection performance but also adds fire resistance and sound insulation functions, making it suitable for various complex environments and meeting higher building standards. The anti-slip textured design on the surface protective layer not only enhances aesthetics but also increases safety when used on the ground, making it suitable for various building application scenarios.
