Description

[0001] The utility model relates to thermal insulation building block technical field more specifically, relate to a novel thermal insulation building block. BACKGROUND

[0002] In the energy consumption of building, the heat conducted through the wall accounts for a considerable proportion, therefore, improving the thermal insulation performance of wall is the key link to realize building energy saving. The traditional building wall material often has limited thermal insulation performance, which is difficult to meet the requirements of modern building energy saving standard.

[0003] Limitations of existing thermal insulation building blocks:

[0004] 1. Many existing thermal insulation building blocks have simple structure, and only rely on single thermal insulation material filling or simple air layer heat insulation, so heat is easily conducted through the solid part of the building block or the weak link of the air layer, resulting in unsatisfactory thermal insulation effect.

[0005] 2. Some thermal insulation building blocks are designed unreasonably in terms of splicing, the connection between the building blocks is not tight, and gaps are easily generated, forming thermal bridge effect. The thermal bridge will cause heat to be quickly transmitted at these positions, greatly reducing the thermal insulation effect of the entire wall, and is also not conducive to the rapid construction, affecting the engineering progress. UTILITY MODEL CONTENT

[0006] The utility model aims at solving the shortcomings in the prior art and provides a novel thermal insulation building block.

[0007] To solve the above problems, the utility model adopts the following technical scheme.

[0013] As a further description of the above technical solutions: the outer surface of the concrete shell is coated with a layer of reflective heat insulation paint.

[0014] As a further description of the above technical solutions: the reinforcing plate is made of aluminum alloy material, and the thickness of the reinforcing plate is 1-2 mm.

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] Firstly, the concrete shell of the heat preservation block is a Z-shaped structure, and the filling cavities arranged in a staggered manner on the two horizontal section structures are filled with a heat preservation layer.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figs. 1-3 As shown, a novel thermal insulation block includes a concrete shell 1 with a Z-shaped structure. This unique shape lays the foundation for the thermal insulation and splicing functions of the entire thermal insulation block. Filling cavities 2 are formed on the two horizontal sections of the concrete shell 1, and the two filling cavities 2 are staggered. This staggered arrangement increases the path length for heat transfer, making it difficult for heat to pass directly through, thereby improving the insulation effect. Each filling cavity 2 is filled with a matching insulation layer 3. Insulation cavities 4 are formed near the top of the concrete shell 1, outside the two insulation layers 3. The two insulation cavities 4 are parallel to the extension direction of the insulation layers 3 and are air cavities. Air is a good insulation medium, effectively preventing heat conduction and further enhancing the thermal insulation performance of the thermal insulation block.

[0027] The outer surface of the concrete shell 1 is coated with a reflective heat-insulating coating layer 11. This coating layer can reflect some of the solar radiation heat, reduce the heat absorbed by the insulation block, and further improve the heat insulation performance of the insulation block, especially suitable for parts of the building exterior walls that are directly exposed to sunlight.

[0028] Insulation Principle: When heat is transferred from one side of the insulation block to the other, it first encounters the concrete shell 1. Since concrete itself has a certain thermal conductivity, heat will be conducted relatively quickly without other measures. However, in this insulation block, heat within the concrete shell 1 first passes through one of the insulation chambers 4. The air in the insulation chamber 4, as a poor conductor of heat, further hinders heat transfer. The relatively large distance between air molecules results in low efficiency of heat transfer through collisions and thermal motion, thus forming the first layer of insulation barrier.

[0029] Then the heat preservation layer 3 in the filling cavity 2 is passed, and the heat preservation layer 3 serves as a second layer of heat insulation barrier. The heat conductivity of the heat preservation layer 3 is much lower than that of the concrete, so the heat preservation layer 3 can effectively block the heat conduction. Moreover, the two filling cavities 2 are arranged in a staggered manner, so the heat needs to be conducted along a complex path in the heat preservation layer 3, thereby greatly reducing the conduction speed. Finally, the heat reaches the other heat insulation cavity 4, thereby forming a third layer of heat insulation barrier.

[0030] In addition, the reflective heat insulation coating layer 11 on the outer surface of the concrete shell 1 can reflect part of the heat, thereby reducing the heat transfer into the heat preservation block and further enhancing the heat preservation effect from the outside.

[0031] Embodiment 2

[0032] Based on the above embodiment, the heat insulation cavity 4 is provided with the reinforcing plate 9. The cross section of the reinforcing plate 9 is a trapezoidal structure connected with each other. The front and back sides of the reinforcing plate 9 are fixedly connected with the inner walls of the heat insulation cavity 4. The reinforcing plate 9 is made of aluminum alloy material. The thickness of the reinforcing plate 9 is 1-2 mm. The arrangement of the reinforcing plate 9 enhances the structural stability of the heat insulation cavity 4.

[0033] The inner walls on the front and back sides of the filling cavity 2 are provided with a plurality of reinforcing ribs 10. The reinforcing ribs 10 are T-shaped structures. The reinforcing ribs 10 on the inner walls on the front and back sides of the filling cavity 2 are arranged in a staggered manner. The reinforcing ribs 10 can improve the structural strength of the filling cavity 2, thereby preventing the heat preservation layer 3 from being deformed during use, so as to ensure the heat preservation effect of the heat preservation layer 3.

[0034] Embodiment 3

[0035] Based on the above embodiment, the top of each of the two horizontal section structures of the concrete shell 1 is provided with the first protruding rib 5. The bottom of each of the two horizontal section structures of the concrete shell 1 is provided with the first recess groove 6 matched with the first protruding rib 5. Each of the two horizontal section structures of the concrete shell 1 is respectively provided with the second protruding rib 7 and the second recess groove 8 matched with each other. The design of the protruding ribs and the recess grooves facilitates the splicing between the heat preservation blocks, reduces the gaps between the blocks, reduces the heat bridge effect, and improves the overall heat preservation and insulation effect while ensuring the convenience of construction.

[0036] Splicing principle: when the heat preservation blocks are spliced, the first protruding rib 5 of one heat preservation block is accurately inserted into the first recess groove 6 of another heat preservation block, and the second protruding rib 7 is inserted into the second recess groove 8. The first protruding rib 5 and the first recess groove 6, and the second protruding rib 7 and the second recess groove 8 are matched with each other. The accurate structure design enables the heat preservation blocks to be tightly spliced, thereby reducing the gaps between the blocks. The reduction of the gaps not only improves the efficiency and accuracy of the construction, but also avoids the rapid heat transfer through the gaps, i.e. reduces the heat bridge effect, thereby ensuring the integrity and effectiveness of the entire heat preservation and insulation system.

[0037] The above merely describes a preferred embodiment of the present application; the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
