Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, and in particular to precast concrete components with thermal insulation and fire resistance. Background Technology

[0002] Precast thermal insulation and fireproof concrete components are building components with thermal insulation and fireproof properties. They are usually composed of multiple parts and have wide applications in construction engineering. One type of component has the following structure:

[0003] 1. Interior wall panel: The inner structure of a prefabricated component;

[0004] 2. Insulation layer: Located between the inner wall panel and the outer wall panel, it provides thermal insulation to maintain a stable indoor temperature and reduce energy consumption.

[0005] 3. Exterior wall panels: As the outer structure of prefabricated components, they directly bear various environmental factors outdoors;

[0006] 4. Fire-retardant coating: Applied to the surface of both interior and exterior wall panels to improve the fire resistance of the components;

[0007] 5. Reinforcing ribs: During the concrete pouring process, the reinforcing ribs are tightly bonded to the concrete, improving the strength, toughness, and deformation resistance of the interior wall panel, thereby enhancing the performance of the entire precast component.

[0008] During the daily use of precast concrete components, the building is exposed to the external environment for a long time. The exterior wall panels are directly subjected to external factors such as wind and rain erosion, ultraviolet radiation, and sand and dust impact. The interior wall panels are also frequently subjected to friction and collision due to daily use, which makes the fireproof coating on the surface of the interior and exterior wall panels easy to wear, thus leading to a decline in fire resistance. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a precast concrete component with thermal insulation and fire resistance, which solves the technical problem that the fire-resistant coating on the surface of the exterior wall panels is easily worn due to external factors such as wind and rain erosion, ultraviolet radiation, and sand and dust impact, while the interior wall panels are also subject to friction and collision due to daily use, thus leading to a decline in fire resistance.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] The precast concrete component with thermal insulation and fire resistance includes an inner wall panel, an insulation layer, an outer wall panel, and a fireproof coating. The insulation layer is located between the inner wall panel and the outer wall panel. There are two fireproof coatings, which are respectively laid on the surface of the inner wall panel and the outer wall panel. The outer wall panel is inlaid with multiple reinforcing ribs. The outer wall panel is provided with a protective structure, which includes a partition, a mesh fabric, and an outer layer. The partition is laid on the outside of the fireproof coating, the mesh fabric is placed on the outside of the partition, and the outer layer is placed on the outside of the mesh fabric. The outer wall panel is provided with an anti-wear layer.

[0012] Preferably, the surface of the partition is covered with an adhesive layer, and the mesh fabric is laid on the outside of the adhesive layer.

[0013] Preferably, an isolation layer is laid on the outside of the mesh fabric, and a noise reduction layer is laid on the outside of the isolation layer.

[0014] Preferably, a reinforcing layer is laid on the outside of the noise reduction layer, and the outer layer is laid on the outside of the reinforcing layer.

[0015] Preferably, the exterior of the interior wall panel is covered with a waterproof coating, the abrasion-resistant layer is laid on the exterior of the waterproof coating, and the exterior of the outer layer is covered with a waterproof layer.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The fire-retardant coating on the exterior wall panels is protected by partitions, mesh fabric, and an outer layer, forming a multi-layered protective structure that effectively resists external physical impacts and environmental erosion. The abrasion-resistant layer of the interior wall panels can resist daily friction and scratches, while the waterproof coating can block indoor moisture and prevent the interior wall panels from getting damp. Therefore, through the corresponding protective structures, the fire-retardant coatings on the surfaces of the exterior and interior wall panels are reduced, thereby preventing a decline in the fire resistance of the precast concrete components.

[0018] 2. The outer layer of the mesh fabric is covered with an isolation layer, a noise reduction layer, and a reinforcement layer. The isolation layer prevents other chemical substances from corroding the mesh fabric and internal structure, while the reinforcement layer uses high-strength materials to further enhance the load-bearing capacity of the protective structure.

[0025] This application provides a thermally insulated and fireproof precast concrete component, which effectively solves the technical problem that the fireproof coating on the surface of the exterior wall panels is easily worn due to the direct exposure of the exterior wall panels to external factors such as wind and rain erosion, ultraviolet radiation, and sand and dust impact, while the interior wall panels are also subject to friction and collision due to daily use, thus leading to a decline in fireproof performance.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the fireproof coating on the surface of both the exterior wall panels is easily worn due to external factors such as wind and rain erosion, ultraviolet radiation, and sand and dust impact, while the interior wall panels are also subject to frequent friction and collisions due to daily use, thus leading to a decrease in fireproof performance. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a precast concrete component with thermal insulation and fire resistance, including an inner wall panel 1, an insulation layer 2, an outer wall panel 3, and a fireproof coating 4. The insulation layer 2 is located between the inner wall panel 1 and the outer wall panel 3. There are two fireproof coatings 4, which are respectively laid on the surfaces of the inner wall panel 1 and the outer wall panel 3. Multiple reinforcing ribs 5 are embedded on the outside of the inner wall panel 1. A protective structure is provided on the outside of the outer wall panel 3. The protective structure includes a partition 6, a mesh cloth 7, and an outer layer 8. The partition 6 is laid on the outside of the fireproof coating 4, the mesh cloth 7 is placed on the outside of the partition 6, and the outer layer 8 is placed on the outside of the mesh cloth 7. An anti-wear layer 9 is provided on the outside of the inner wall panel 1, which is laid on the outside of the fireproof coating 4.

[0029] The partition 6 isolates the fireproof coating 4 from direct impact and abrasion from the outside world, providing initial protection. The mesh fabric 7 disperses the external forces acting on the partition 6, enhancing the tensile and tear resistance of the entire protective structure. The outer layer 8 serves a certain decorative function, improving the building's appearance.

[0030] An adhesive layer 10 is laid on the surface of the partition 6, and a mesh cloth 7 is laid on the outside of the adhesive layer 10 to adhere the mesh cloth 7 to the partition 6, so that the two form a tight connection.

[0031] An isolation layer 11 is laid on the outside of the mesh fabric 7 to prevent harmful substances such as acids, alkalis, and salts from corroding the mesh fabric 7 and the internal structure, thus protecting the internal materials.

[0032] A noise reduction layer 12 is laid on the outside of the isolation layer 11. Through its special porous structure, it reduces the transmission of external noise into the room and achieves the effect of sound insulation and noise reduction.

[0033] A reinforcing layer 13 is laid on the outside of the noise reduction layer 12, and the outer layer 8 is laid on the outside of the reinforcing layer 13 to improve the overall strength and rigidity of the protective structure and provide stable support for the outer layer 8.

[0034] The outer surface of the abrasion-resistant layer 9 is covered with a waterproof coating 14, and the outer surface of the outer layer 8 is covered with a waterproof layer 15, which prevents moisture from penetrating into the interior of the component and improves the waterproof performance and service life of the component.

[0035] Working principle:

[0036] In the first step, the fireproof coating 4 on the exterior wall panel 3 is protected by the partition 6, the mesh 7, the outer layer 8, and the waterproof layer 15. The partition 6 directly covers the fireproof coating 4, acting as a buffer layer to weaken the impact of external physical impacts on the fireproof coating 4. The mesh 7 is tightly attached to the partition 6 with the help of the adhesive layer 10. It uses its high strength and high toughness to evenly distribute the external force and avoid localized damage to the partition 6. The outer layer 8 acts as an outer barrier to protect the internal structure. The waterproof layer 15 prevents moisture penetration and reduces the performance of the fireproof coating 4. The abrasion-resistant layer 9 of the interior wall panel 1 can resist daily friction and scratches. The waterproof coating 14 can block indoor moisture and prevent the interior wall panel 1 from getting damp, ensuring that the fireproof coating 4 can function stably.

[0037] The second step involves laying an isolation layer 11, a noise reduction layer 12, and a reinforcement layer 13 on the outside of the mesh fabric 7. The isolation layer 11 prevents other chemical substances from corroding the mesh fabric 7 and its internal structure, thus extending the service life of the components. The noise reduction layer 12 reduces the decibels of external noise entering the room. The reinforcement layer 13 uses high-strength materials to further enhance the load-bearing capacity of the protective structure and provides support for the outer layer 8.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
