Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, and more specifically, it relates to a composite wall panel that blocks heat and cold exchange. Background Technology
[0002] Composite wall panels are a new generation of high-performance building interior partitions produced industrially. They are made of a variety of building materials and replace traditional bricks and tiles. They have obvious advantages such as being environmentally friendly, energy-saving, pollution-free, lightweight, earthquake-resistant, fireproof, heat-insulating, sound-insulating, and quick to install.
[0003] In daily life, people need a comfortable living and working environment that is warm in winter and cool in summer. Therefore, the quality of a house's insulation has a great impact on people's lives and work. Most existing houses have insulation treatment on the exterior walls, but the interior partition walls are not treated. Since different rooms have different uses, they sometimes need to maintain their own temperatures. However, the partition walls between different rooms do not have self-insulating properties, which leads to rapid heat exchange between the different rooms and makes it impossible for them to keep warm.
[0004] Therefore, a composite wall panel is needed to block heat exchange and solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a composite wall panel that blocks heat exchange, so as to solve the problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A composite wall panel for blocking heat and cold exchange includes a surface layer and a base layer. Several contact layers are fixedly connected to the surface layer and the base layer on their opposite sides. An insulation cavity is formed between the contact layers and the surface layer or the base layer fixedly connected to them. There is a gap between the contact layers on the surface layer and the base layer, and there is a gap between the contact layers on the base layer and the surface layer. The contact layers on the surface layer and the contact layers on the base layer are in line contact.
[0008] The technical solution of this utility model is further configured such that: the contact layer is arrayed along the length direction of the surface layer or the base layer connected to it, and the cross section of the contact layer is arc-shaped.
[0009] The technical solution of this utility model is further configured such that heat insulation film is provided on both the inner and outer walls of the contact layer.
[0010] The technical solution of this utility model is further configured such that the heat insulation cavity is filled with rigid polyurethane foam.
[0011] The technical solution of this utility model is further configured such that: a connecting frame for connecting the two is fixedly connected between the surface layer and the base layer, and the contact layer is located within the connecting frame.
[0012] The technical solution of this utility model is further configured as follows: the connecting frame includes a frame one and a frame two, the cross-section of the frame one and the frame two are both U-shaped, the two ends of the base layer in the length direction are respectively fixedly connected to a connector one and a connector two, the connector two is detachably connected to the connector one, and both the connector one and the connector two are located between the frame one and the frame two.
[0013] The technical solution of this utility model is further configured as follows: the thickness of both the first connector and the second connector is less than the thickness of the connecting frame; the second connector has a groove for accommodating the first connector; and a snap-fit component is fixedly connected to the inner wall of the groove; and the outer wall of the first connector has a snap-fit groove that matches the snap-fit component.
[0014] The technical solution of this utility model is further configured as follows: a fastening bolt for abutting against the second connecting member is threaded on the surface layer, and a clamping plate is fixedly connected to the end of the fastening bolt that abuts against the second connecting member.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] By setting contact layers on the surface layer and the base layer and controlling the contact area of the contact layers on both, the heat transfer path is reduced, the heat transfer efficiency is decreased, and heat conduction is not effectively carried out, thereby improving the thermal insulation effect of this composite wall panel. It makes it difficult for heat to be transferred between different rooms. In addition, the thermal insulation film on the contact layer can reflect the heat radiated by objects at room temperature, reducing heat loss or the introduction of external heat. The rigid polyurethane foam plastic in the insulation cavity, due to its low thermal conductivity, can further enhance the thermal insulation effect of this composite wall panel.
[0017] The two composite wall panels are connected and installed by connector one and connector two set on the base layer. Since connector one and connector two are both set on the base layer, it is difficult for heat on the base layer to be transferred to the surface layer. The fastening bolts on the surface layer can enhance the firmness of the connection between connector one and connector two and prevent them from separating. At the same time, in this way, the surface layer only uses a small area of abutment plate to contact connector two, further reducing the heat transfer path and enhancing the heat preservation effect.

[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example
[0024] refer to Figures 1 to 4 As shown, this utility model provides a composite wall panel for blocking heat exchange, including a surface layer 1 and a base layer 2. Several contact layers 3 are fixedly connected to the surface layer 1 and the base layer 2 facing each other. A heat insulation cavity 4 is formed between the contact layers 3 and the surface layer 1 or the base layer 2 fixedly connected thereto. There is a gap between the contact layers 3 on the surface layer 1 and the base layer 2, and there is a gap between the contact layers 3 on the base layer 2 and the surface layer 1. The contact layers 3 on the surface layer 1 and the contact layers 3 on the base layer 2 are in line contact.
[0025] refer to Figures 1 to 4 As shown, the contact layer 3 is arrayed along the length of the surface layer 1 or the base layer 2 connected to it. The cross-section of the contact layer 3 is arc-shaped. The distance between adjacent contact layers 3 is less than the straight distance between the two ends of the contact layer 3. The inner and outer walls of the contact layer 3 are provided with heat insulation film. The heat insulation cavity 4 is filled with rigid polyurethane foam.
[0026] refer to Figures 1 to 4As shown, a connecting frame 5 is fixedly connected between the surface layer 1 and the base layer 2 to connect the two. The contact layer 3 is located inside the connecting frame 5. The connecting frame 5 includes a frame body 1 and a frame body 2. The cross-sections of the frame body 1 and the frame body 2 are both U-shaped. Connector 1 6 and connector 2 7 are fixedly connected to both ends of the base layer 2 in the length direction, respectively. Connector 2 7 is detachably connected to connector 1 6. Both connector 1 6 and connector 2 are located between the frame body 1 and the frame body 2. The thickness of connector 1 6 and connector 2 7 is less than the thickness of the connecting frame 5. Connector 2 7 has a groove 8 for accommodating connector 1 6, and a snap-fit 9 is fixedly connected to the inner wall of the groove 8. Connector 1 6 has a snap-fit groove 10 that matches snap-fit 9 on its outer wall. The surface layer 1 is threaded with a fastening bolt 11 for abutting against connector 2 7. A clamping plate 12 is fixedly connected to the end of the fastening bolt 11 that abuts against connector 2 7.
[0027] With the above-described structure, when two composite wall panels need to be connected and installed, one of the composite wall panels can be rotated to allow connector 2 7 to enter between frame 1 and frame 2, thereby allowing connector 1 6 to enter the groove 8 on connector 2 7. During this process, the snap-fit 9 on connector 2 7 also enters the snap-fit groove 10 on connector 1 6, thus completing the connection between connector 1 6 and connector 2 7, realizing the connection of the two composite wall panels. Finally, rotating the fastening bolt 11 on the surface layer 1 causes the clamping plate 12 to engage with the surface layer 1 and... The base layer 2 moves towards the base layer 2 and abuts against the surface of the connector 7, completing the connection and installation of the two composite wall panels. The connector 7 and the abutment plate 12 can be made of rubber and metal respectively. Since rubber is a poor conductor of heat, heat is not easily transferred from the connector 7 and the abutment plate 12, thus improving the thermal insulation performance of the two composite wall panels. In this way, the connection strength can be guaranteed while minimizing the area of the connection frame 5 that directly connects the surface layer 1 and the base layer 2, thereby improving the overall thermal insulation effect.
[0028] refer to Figures 1 to 4As shown, in summary, by setting contact layers 3 on the surface layer 1 and the base layer 2, and controlling the contact area of the contact layers 3 on both, the heat transfer path is reduced, the heat transfer efficiency is decreased, and heat conduction is rendered ineffective, thereby improving the thermal insulation effect of this composite wall panel. This makes it difficult for heat to transfer between rooms. Furthermore, the thermal insulation film on the contact layer 3 can reflect the heat radiated by objects at room temperature, reducing heat loss or the influx of external heat. The rigid polyurethane foam in the insulation cavity 4, due to its low thermal conductivity, further enhances the thermal insulation effect of this composite wall panel. The thermal insulation effect of the composite wall panel is achieved by connecting two composite wall panels through connector 6 and connector 7 set on the base layer 2. Since connector 6 and connector 7 are both set on the base layer 2, it is difficult for heat on the base layer 2 to be transferred to the surface layer 1. The fastening bolts 11 on the surface layer 1 can enhance the firmness of the connection between connector 6 and connector 7 and prevent them from separating. At the same time, in this way, the surface layer 1 only uses a small area of the clamping plate 12 to contact connector 7, further reducing the heat transfer path and enhancing the thermal insulation effect.
[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
