Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a thermal insulation exterior wall board. Background Art

[0002] The panels installed on the exterior surface of the building are exterior wall panels. The insulation of the exterior wall panels can effectively prevent heat loss and improve the heating effect. The traditional process is to paste the insulation board on the surface of the exterior wall panel. However, the pasted insulation board is easy to fall off, causing the danger of falling objects from high altitude. In addition to factors such as high manufacturing and construction costs, exterior wall panels with insulation functions have appeared in the prior art. In winter, the indoor temperature is higher than the outdoor temperature, and heat is lost from the higher indoor temperature to the lower outdoor temperature. About 70% to 80% of the heat is lost to the outside through the walls and roofs, and the remaining 20% ​​to 30% is lost to the outside through the gaps of doors and windows. There are three main ways of heat transfer between the wall and the air: conduction, convection and radiation. 1. Conduction: refers to the process of heat transfer from high temperature to low temperature, in which heat is transferred through direct contact between objects. For example, hot water taken out of a thermos will be transferred to a cup, making the cup warm. 2. Convection: refers to the heat conduction inside the fluid, which can also be understood as the transfer of heat through flowing gas or liquid. For example, a cool breeze from a fan will lower the temperature of a room. 3. Radiation: refers to the transfer of heat through electromagnetic radiation. For example, the heat from the sun is transferred to the earth through radiation.

[0003] In order to reduce the heat loss of the wall, the utility model patent with the authorization announcement number CN220301555U provides an exterior wall panel with thermal insulation rock wool, including a wall panel body and a wall panel base fixedly connected inside the wall panel body, and the interior of the wall panel body is filled with a rock wool board. The utility model enhances the thermal insulation performance of the wall panel body by arranging the rock wool board, and through the characteristics of the rock wool board, the wall panel body has good waterproof performance, thereby extending the service life of the wall panel body.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art: similar to the above-mentioned patent technology, the cross-section of the insulation layer in the prior art is rectangular as a whole, and the internal insulation layer is also rectangular, but the space between the insulation layers is a load-bearing material with poor insulation effect, and the two ends of the load-bearing material are straightly connected to the indoor and outdoor, resulting in a large amount of heat loss; if the spacing between the insulation boards is reduced, the thickness of the load-bearing layer will be reduced, which cannot meet the strength requirements. Summary of the invention

[0037] An inner core 13 is further disposed at the center of the thermal insulation layer 12 . The inner core 13 is in a long strip shape, and the cross section of the inner core 13 is in a rectangular or T shape.

[0038] like Figure 2 , Figure 7 , Fig. 9 As shown, the thermal insulation exterior wall panel also includes a side template 2, which is arranged on both sides of the thermal insulation exterior wall panel. The side template 2 and the main template 1 together form a rectangular thermal insulation exterior wall panel. The cross section of the side template 2 is L-shaped. The side template 2 includes a supporting shell 21 and a thermal insulation layer 22. The thermal insulation layer 22 is a long strip with an L-shaped cross section.

[0039] The support shell 1 11 , the inner core 13 , and the support shell 2 21 are autoclaved aerated concrete panels, and the insulation layer 12 is a rock wool board.

[0040] Sealing gaskets are provided in the gap between the side template 2 and the main template 1 , and in the gap between the main templates 1 and the main templates 1 .

[0042] Embodiment 2: Fig.15 This is the second embodiment of the utility model, which is different from the first embodiment in that the two angles at the top of the raised part of the main template 1 are acute angles. The angle between the top edge and the upper side edge is an acute angle. By setting the two angles at the top of the raised part of the main template 1 to be acute angles, the strength support part formed by the support shell 11 between the insulation layer 12 is a "Z" shape with an acute angle, which extends the distance of heat conduction, makes it difficult for heat to radiate out by refraction, and blocks the radiation path more thoroughly.

[0043] The steps of installing the thermal insulation exterior wall panel are as follows: 1. Install the first side template 2 or main template 1; 2. When installing the next side template 2 or main template 1, bury the tie rod 33 between the two opposite pull sleeves 31 in advance; 3. Manually press the side template 2 or main template 1, and manually pull the tie rod 33 until the pull block is stuck in the V-shaped protrusions of the pull sleeves 31 on both sides; 4. Screw the nut 32 onto the screw of the tie rod 33 and tighten it until the pull block fits with the nut 32. During this period, the V-shaped groove on the pull block forces the V-shaped protrusions on the pull sleeves 31 on both sides to gradually approach and finally fit together, completing the fitting of the side templates 2 or main templates 1 on both sides; 5. Saw off the redundant screws on the tie rod 33, and complete the installation and tightening of a side template 2 or main template 1. Repeat steps 2 to 5 until the assembly of the entire thermal insulation exterior wall panel is completed.

[0044] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
