Description

Technical Field

[0001] This utility model relates to the technical field of polystyrene composite insulation board, and in particular to an external wall insulation structure of polystyrene composite insulation board. Background Technology

[0002] In the field of building energy conservation, external wall insulation systems have become one of the core energy-saving structures in modern buildings due to their ability to effectively reduce building energy consumption and improve the indoor thermal environment. Among them, polystyrene composite insulation boards, with their advantages of low thermal conductivity, lightweight, and convenient construction, have become one of the mainstream insulation materials for external wall insulation systems and are widely used in the exterior walls of multi-story and high-rise buildings. However, existing external wall insulation structures using polystyrene composite insulation boards directly bond and fix the insulation boards to the exterior wall. Under the long-term action of the insulation board's own weight, the fixing strength of a single bond is insufficient to support it, which easily leads to the risk of localized hollowing or even complete detachment of the insulation board. Moreover, when subjected to external impact, the force is easily concentrated in a localized area, causing cracking or detachment, which exacerbates the degradation of insulation performance and structural damage. Utility Model Content

[0003] The technical problem this utility model aims to solve is to address the aforementioned technical deficiencies by providing a polystyrene composite insulation board external wall insulation structure. This structure is more firmly fixed to the external wall and is less prone to cracking or falling off when subjected to external impact.

[0004] The technical solution adopted by this utility model is as follows: A polystyrene composite insulation board external wall insulation structure is provided, comprising a leveling layer, an adhesive layer, an insulation layer, a plastering mortar and fiberglass mesh layer, and a decorative layer arranged sequentially; the insulation layer is made of polystyrene composite insulation board; multiple pre-set grooves are opened on the insulation layer; expansion bolts are also included, and the bolt heads of the expansion bolts are fixedly connected to limit plates, the limit plates corresponding to the pre-set grooves; a fixing groove is provided on the outer side of the limit plates; and flexible gaskets corresponding to the pre-set grooves are also included.

[0005] To further optimize this technical solution, a flexible gasket for the external wall insulation structure of a polystyrene composite insulation board is a butyl rubber self-adhesive gasket.

[0006] To further optimize this technical solution, a leveling layer for an external wall insulation structure using polystyrene composite insulation board is made of cement mortar.

[0007] To further optimize this technical solution, the adhesive layer of a polystyrene composite insulation board exterior wall insulation structure is an adhesive mortar.

[0008] To further optimize this technical solution, both the limiting plate and the expansion bolts of the polystyrene composite insulation board external wall insulation structure are made of metal.

[0009] To further optimize this technical solution, the decorative layer of a polystyrene composite insulation board exterior wall insulation structure is made of real stone paint.

[0010] Compared with traditional polystyrene composite insulation board external wall insulation structures, the advantages of this utility model are as follows:

[0011] 1. The leveling layer and adhesive layer are set up to fill the height difference of the wall, and the high-strength adhesive force fixes the insulation layer to prevent the insulation layer from failing to bond.

[0012] 2. The installation of insulation layer, pre-set groove, flexible gasket, and expansion bolts, along with the dual fixation of the insulation layer through adhesive layer and mechanical anchoring, significantly improves the overall stability.

[0013] 3. The installation of expansion bolts, limiting plates, flexible gaskets, pre-set grooves, insulation layers, plastering mortar and fiberglass mesh layers, and fixing grooves disperses the local external force to a larger surrounding area when the decorative layer is subjected to external impact, avoiding cracking or detachment caused by concentrated external force, and making the outer structure less prone to damage when subjected to force.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, an external wall insulation structure using polystyrene composite insulation board includes a leveling layer 1, an adhesive layer 2, an insulation layer 3, a plastering mortar and fiberglass mesh layer 4, and a decorative layer 5 arranged sequentially. The insulation layer 3 is made of polystyrene composite insulation board. Multiple pre-set grooves 6 are formed on the insulation layer 3. Expansion bolts 7 are also included, with the bolt heads of the expansion bolts 7 fixedly connected to limit plates 8, which correspond to the pre-set grooves 6. A fixing groove 9 is provided on the outer side of the limit plate 8. Flexible gaskets 10 corresponding to the pre-set grooves 6 are also included. The flexible gaskets 10 are butyl rubber self-adhesive gaskets. The leveling layer 1 is cement mortar. The adhesive layer 2 is bonding mortar. The bolts of the limit plate 8 and the expansion bolts 7 are both made of metal. The decorative layer 5 is made of stone paint.

[0020] When using it, the leveling layer 1 is set up by first leveling the exterior wall with cement mortar to fill the height difference of the wall and provide a flat, dry and solid base layer for the bonding layer to avoid the failure of the insulation layer 3 bonding.

[0021] After the leveling layer 1 is dry and firm, the insulation layer 3 is bonded to the adhesive layer 2. The high-strength adhesive force fixes the insulation layer 3, which bears the weight of the insulation layer 3 and part of the external load, thus preventing the insulation layer 3 from becoming hollow and falling off.

[0022] The insulation layer 3 is a polystyrene composite insulation board, which has the effects of heat preservation, heat insulation and waterproofing;

[0023] The plastering mortar and fiberglass mesh layer 4 protect the insulation layer 3 from external erosion, disperse stress through the fiberglass mesh to prevent cracking of the plastering layer, and connect the decorative layer 5.

[0024] Decorative layer 5 is made of real stone paint, which beautifies the building's appearance, blocks rainwater, and protects insulation layer 3;

[0025] After the insulation layer 3 is fixed, a hole is precisely drilled at the position of the preset groove 6. Then, the flexible gasket 10 is pasted into the preset groove 6 to ensure that the gasket is completely attached to the groove and there is no looseness. Next, the expansion bolt 7 is inserted into the drilled hole. Through the mechanical interlocking of the bolt expansion end with the base wall, the insulation layer 3 is fixed by the double fixation of the adhesive layer and mechanical anchoring, which greatly improves the overall stability.

[0026] The limiting plate 8 of the expansion bolt 7 and the flexible gasket 10 are both embedded in the preset groove 6, flush with the surface of the insulation layer 3, without protrusion, laying a flat foundation for subsequent plastering construction; when the plastering mortar and the fiberglass mesh layer are applied, the textured structure of the fixing groove 9 on the surface of the limiting plate 8 can form a tight mechanical interlock with the mortar. After the mortar fills the gap of the fixing groove 9, it forms a firm overall connection with the fiberglass mesh and the limiting plate 8; when the decorative layer 5 is subjected to external impact, the distributed expansion bolts 7 and the limiting plate 8 can play a rigid support role. The limiting plate 8, through its stable connection with the plastering layer, disperses the local external force to a larger surrounding area, avoiding cracking or detachment caused by concentrated external force, and the outer structure is less prone to damage when subjected to force.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
