Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a lightweight thermal insulation exterior wall assembly panel. Background Technology

[0002] With the deep integration of global building industrialization and green energy-saving concepts, prefabricated buildings have become the mainstream direction of modern building development due to their advantages such as high construction efficiency, controllable quality, and low carbon and environmental protection. As a core component of building envelope, the performance of exterior wall prefabricated panels directly affects building energy consumption, indoor environmental comfort, and service life.

[0003] Although the existing exterior wall panels have achieved splicing, the splicing method relies on adhesives or mechanical anchors to fix each other. This makes them prone to deformation due to temperature differences and wind pressure loads, which can lead to hollowing and falling off. Most existing exterior wall panels have relatively simple structures and are not efficient enough in terms of lightweight insulation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lightweight thermal insulation exterior wall assembly panel, which aims to improve the problems of insufficient reliability of splicing connection of exterior wall assembly panels and the single and inefficient lightweight thermal insulation structure of the wall in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight thermal insulation exterior wall panel includes a wall panel, characterized in that: a fixing strip is fixedly connected to the right side of the wall panel, a sliding groove is opened on the left side of the wall panel, fixing blocks one and two are fixedly connected to the left and right sides of the front of the wall panel, fixing grooves one and two are opened on the left and right sides of the rear of the wall panel, and multiple evenly distributed positioning holes are opened on the top of the wall panel;

[0007] As a further description of the above technical solution:

[0008] The wall panel includes an insulation layer, a reflective heat insulation layer is fixedly connected to the top of the insulation layer, a humidity regulating and sound insulation layer is fixedly connected to the bottom of the insulation layer, and multiple evenly distributed honeycomb holes are opened on the top of the insulation layer.

[0009] As a further description of the above technical solution:

[0010] The top of the wall panel is fixedly connected with multiple evenly distributed guide strips, and the bottom of the wall panel is provided with multiple evenly distributed ventilation slots.

[0011] As a further description of the above technical solution:

[0012] The air guide strip is fixedly connected to the top of the reflective heat insulation layer, and the ventilation slot is opened at the bottom of the humidity-regulating and sound-insulating layer;

[0013] As a further description of the above technical solution:

[0014] The first fixing block is slidably connected inside the first fixing groove, and the second fixing block is slidably connected inside the second fixing groove;

[0015] As a further description of the above technical solution:

[0016] The fixing strip is slidably connected inside the slide groove;

[0017] As a further description of the above technical solution:

[0018] The first fixing block is fixedly connected to the outside of the second fixing block;

[0019] As a further description of the above technical solution:

[0020] The honeycomb cells are hexagonal in shape.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a three-dimensional stable structure with front and rear limiting and left and right interlocking is constructed by forming a sliding fit between the fixing block one and fixing block two and the fixing groove one and fixing groove two, and then the sliding connection between the fixing strip and the sliding groove. This improves the wind resistance and stability compared with the traditional single anchor bolt connection, and effectively avoids the problems of hollowing and falling off caused by wind pressure load or temperature difference deformation.

[0023] 2. In this utility model, a three-layer composite structure is formed by a reflective heat insulation layer, a thermal insulation layer and a humidity-regulating and sound-insulating layer, which achieves the effects of lightweight insulation and environmental adaptability. The reflective heat insulation layer effectively shields the heat generated by solar radiation, and combined with the low thermal conductivity of the hexagonal honeycomb holes of the thermal insulation layer, it significantly reduces the heat transfer coefficient of the exterior wall. The humidity-regulating and sound-insulating layer can reduce air noise while balancing indoor humidity, thus improving living comfort. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-5 This utility model provides an embodiment of a lightweight thermal insulation exterior wall panel, comprising a wall panel 1. The wall panel 1 serves as the core load-bearing body and is made of layered lightweight composite material. A fixing strip 2 is fixedly connected to the right side of the wall panel 1, and a sliding groove 3 is provided on the left side of the wall panel 1. The fixing strip 2 is slidably connected inside the sliding groove 3. The fixing strip 2 has a T-shaped cross-section and is used to cooperate with the sliding groove 3 of the adjacent wall panel 1, providing horizontal sliding guidance, preliminary positioning, and fixing functions. Fixing blocks 4 are fixedly connected to the left and right sides of the front of the wall panel 1. The fixing blocks 4 have a rectangular cross-section. Fixing blocks 5 are fixedly connected to the left and right sides of the front of the wall panel 1. The fixing blocks 5 are inverted trapezoidal. The wall panel 1 has a block structure. Fixing block 1 4 is fixedly connected to the outside of fixing block 2 5. Fixing groove 1 6 is provided on both the left and right sides of the rear of the wall panel 1. Fixing block 1 4 is slidably connected inside the fixing groove 1 6. By sliding the fixing block 1 4 into the fixing groove 1 6, the load distribution is more uniform, avoiding material damage caused by local stress concentration. Fixing groove 2 7 is provided on both the left and right sides of the rear of the wall panel 1. Fixing block 2 5 is slidably connected inside the fixing groove 2 7. By sliding the fixing block 2 5 into the fixing groove 2 7, the front and rear directions of the wall panel 1 are limited. Multiple evenly distributed positioning holes 8 are provided on the top of the wall panel 1. The positioning holes 8 enable precise control of the verticality and elevation of the wall panel 1.

[0033] Reference Figure 4 and Figure 5The present invention provides an embodiment of the following: the wall panel 1 includes an insulation layer 10, which is made of flame-retardant EPS foam and mainly serves as the core insulation layer to block heat conduction. A reflective insulation layer 9 is fixedly connected to the top of the insulation layer 10. The reflective insulation layer 9 is made of aluminum foil composite fiberglass cloth, which can reduce the temperature of the outer surface of the exterior wall. A moisture-regulating and sound-insulating layer 11 is fixedly connected to the bottom of the insulation layer 10. The moisture-regulating and sound-insulating layer 11 is made of water-repellent rock wool board and has both moisture-proof and noise-reducing functions, thereby achieving the effect of improving the indoor thermal and humidity environment and sound environment. The top of the insulation layer 10 has multiple evenly distributed honeycomb holes 14. The honeycomb holes 14 are hexagonal in shape. The honeycomb holes 14 can reduce the amount of hole wall material used, while improving the overall rigidity of the insulation layer 10 and reducing heat loss.

[0034] Reference Figure 3 and Figure 5 In one embodiment of this utility model, a plurality of evenly distributed guide strips 12 are fixedly connected to the top of the wall panel 1. The guide strips 12 are fixedly connected to the top of the reflective heat insulation layer 9. The inclined design of the guide strips 12 can guide rainwater to be discharged to both sides. A plurality of evenly distributed ventilation slots 13 are opened at the bottom of the wall panel 1. The ventilation slots 13 are opened at the bottom of the humidity regulating and sound insulation layer 11. The ventilation slots 13 are elongated and can discharge hot air from the inner cavity of the wall through the thermal pressure effect in summer, thereby reducing the temperature of the insulation layer 10.

[0035] Working principle: When wall panel 1 needs to be spliced ​​and installed, the T-shaped fixing strip 2 and the sliding groove 3 can be slidably connected to achieve a preliminary positioning. Then, the front rectangular fixing block 1 4 and the inverted trapezoidal fixing block 2 5 are embedded into the fixing groove 1 6 and fixing groove 2 7 at the rear of another wall panel 1. The top positioning hole 8 is then matched with the fixing components to form a three-dimensional connection system, which meets the dual requirements of prefabricated buildings for installation efficiency and structural reliability. The outer aluminum foil reflective heat insulation layer 9 reflects solar radiation heat, which reduces the temperature of the outer surface of the exterior wall. The hexagonal honeycomb holes 14 of the middle flame-retardant EPS insulation layer 10 form an independent air cavity, blocking heat conduction and improving structural rigidity. The inner water-repellent rock wool moisture-regulating and sound-insulating layer 11 can reduce external noise. The top guide strip 12 guides rainwater to drain quickly, and the bottom ventilation groove 13 forms air convection. Through the above structure and comprehensive comparison with traditional exterior walls, the comfort of living is effectively improved.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
