AI Technical Summary
The core material of existing thermal insulation partition boards has low compressive strength, making them prone to compression deformation or structural damage during transportation and use. In particular, the panels are prone to denting or cracking at the joints under localized concentrated loads. Furthermore, increasing the density or thickness of the core material will increase costs and weight.
The structure employs a polyurethane core board, reinforcing plate, and support tube. The support tube is filled with polyurethane core material and fixed by a limiting component. The support tube and polyurethane core board are interlocked. The support tube and reinforcing plate provide support, disperse stress, and reduce deformation.
It improves the compressive strength of the thermal insulation board, avoids core board dents and joint cracks, while maintaining lightweight and thermal insulation performance, reducing material costs and construction complexity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building wall materials technology, specifically a thermal insulation board for lightweight composite interior walls. Background Technology
[0002] Insulated partition wall panels are lightweight wall materials that combine the functions of partitioning and thermal insulation. They are usually composed of an insulating core material (such as polystyrene, rock wool, aerogel, etc.) and two reinforcing panels on both sides (such as calcium silicate board, gypsum board, or fiber cement board). They are characterized by low thermal conductivity, which can effectively reduce indoor and outdoor heat transfer, while meeting building energy conservation requirements. They are suitable for interior partition walls or partition walls where high thermal insulation performance is required.
[0003] Currently, most thermal insulation partition boards on the market use lightweight insulation materials as the core layer. Although they have good thermal insulation performance, the compressive strength of the core material is generally low. During transportation, installation, or long-term use, they are prone to compression deformation or even structural damage, affecting the overall stability of the wall. In particular, when the board is subjected to localized concentrated loads, the core layer is unable to effectively disperse stress, leading to panel dents or joint cracks. Although existing technologies can improve strength by increasing panel thickness or using high-density core materials, this will significantly increase material costs and weight, and reduce construction efficiency.
[0004] Therefore, there is an urgent need for an innovative structural design that can maintain lightweight insulation properties while effectively enhancing compressive strength. Utility Model Content

The push block 905 pushes the insert block 901 to retract into the first slide groove 12. The insert block 901 compresses the compression spring 903, and the collar 8 can be sleeved on one end of the support tube 7. By releasing the push block 905, the compression spring 903 can push the insert block 901 into the slot 11, thereby quickly fixing the collar 8, preventing the support tube 7 from loosening and falling off, and facilitating its quick assembly. In this embodiment, preferably, a groove 3 is provided on one side of the polyurethane core board 1, and a reinforcing plate 6 is embedded in the groove 3.
