Description

Technical Field

[0001] The utility model relates to a polyurethane composite board, in particular to an anti-falling polyurethane composite board thermal insulation system. Background Art

[0002] In construction projects, polyurethane thermal insulation composite panels, as an efficient and energy-saving building material, are widely used in exterior wall insulation systems due to their excellent thermal insulation performance and light weight. However, despite its significant advantages, the challenges faced during the actual installation process, especially when fixing it to the base wall, cannot be ignored.

[0003] In order to ensure that the polyurethane thermal insulation composite board can be firmly attached to the base wall, composite glue is often used as the main bonding material during the construction process. With its good bonding strength, weather resistance and ease of construction, composite glue ensures the effective connection between the insulation board and the wall to a certain extent. However, due to the complex and changeable external environmental conditions, such as extreme temperature, humidity changes, strong winds, ultraviolet radiation and possible rainwater penetration, these factors may have an adverse effect on the bonding performance of the composite glue, thereby increasing the risk of polyurethane thermal insulation composite panels falling off.

[0004] Specifically, composite adhesive exposed to harsh environments for a long time may age, harden or lose its viscosity, resulting in a weakened bond between the composite adhesive and the insulation board and the base wall. In addition, the quality of the base wall treatment is also one of the key factors affecting the fixing effect of the insulation board. If the base wall is uneven, oily, dusty or not pre-treated according to the specifications, it will directly affect the bonding effect of the composite adhesive, thereby increasing the possibility of the insulation board falling off. Utility Model Content

[0005] In order to overcome the disadvantage that the existing polyurethane thermal insulation composite board is fixed to the base wall by composite glue, and its adhesion stability is lost over time, the utility model provides an anti-falling polyurethane composite board thermal insulation system.

[0007] Preferably, the screw rod is provided with symmetrical threads.

[0008] Preferably, it also includes a rotating block, a handle and a locking block. The locking block is rotatably connected to the middle of the sleeve. The middle of the locking block is fixedly connected to the rotating block. The rotating block is provided with a handle. The end of the screw is provided with a spline. The rear end of the locking block is engaged with the spline.

[0009] Preferably, a protective plug is also included, and the protective plug is arranged on the sleeve, specifically located outside the locking block.
