[0002] The heat preservation and non - removable formwork is one of the commonly used building components in modern architecture. It combines the heat preservation function with the function of building casting formwork. After construction, it does not need to be removed, the construction operation is convenient, and it can effectively shorten the construction period. The heat preservation and non - removable formwork usually consists of a vacuum insulation panel and an outer cladding layer. Since the cladding layer needs to be made of materials with low thermal conductivity, its flexural strength performance is poor. The heat preservation and non - removable formwork is often damaged due to bending force during transportation and construction, resulting in large breakage losses. Moreover, after the heat preservation and non - removable formwork is installed, when the surface of the building component is subjected to a large impact, the heat preservation and non - removable formwork is also easily damaged, resulting in the leakage of the vacuum insulation panel inside and the loss of heat insulation capacity. Therefore, a heat preservation and non - removable formwork with high flexural strength performance is needed to solve the above problems. Summary of the Utility Model

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.
[0023] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:
[0024] Embodiment 1
[0025] A thermal insulation, non-disassembly formwork with high flexural resistance comprises a vacuum insulation panel 1, a coating layer 2, an outer layer 3 and an inner layer 4. The vacuum insulation panel 1 is made of a core material coated with a high-barrier film and vacuum-sealed. The core material is made of silica or glass fiber. The high-barrier film comprises an outer layer film, a middle layer film and an inner layer film arranged in sequence from the outside to the inside. The outer layer film is made of nylon or PVC, the middle layer film is a composite of at least one of VMPET film, PVDC film, PVA film, PP film and PVC film, and the inner layer film is made of PE.
[0026] The outside of the vacuum insulation panel 1 is evenly covered with a coating layer 2, which is formed by foaming expandable polystyrene foam particles. The coating layer 2 formed by foaming expandable polystyrene foam particles can protect the vacuum insulation panel 1, and the coating layer 2 has excellent properties such as high pressure resistance, moisture resistance, light weight, corrosion resistance, super aging resistance, and low thermal conductivity, and can be used as a template for pouring concrete for building walls.
[0027] The two end surfaces of the covering layer 2 are respectively provided with an outer layer 3 and an inner layer 4, the outer layer 3 includes a plastering layer 31 and a finishing layer 32, the plastering layer 31 is provided on the surface of the covering layer 2, and the surface of the plastering layer 31 is provided with a finishing layer 32; during construction, the outer layer 3 faces the indoor or outdoor space, the plastering layer 31 is constructed of plastering mortar and alkali-resistant glass fiber mesh, and plays a role in protecting the covering layer 2 and the wall from cracking, waterproofing, impact resistance and fire prevention; the finishing layer 32 is constructed of paint or finishing mortar and plays a decorative role.
[0028] The inner surface layer 4 includes an adhesive layer 41 and a leveling waterproof layer 42. The adhesive layer 41 is arranged on the surface of the covering layer 2, and the surface of the adhesive layer 41 is provided with a leveling waterproof layer 42. During construction, the inner surface layer 4 faces the side where concrete needs to be poured, and plays a role in shaping the concrete. The adhesive layer 41 is constructed by brushing with an adhesive and plays an auxiliary bonding role. The leveling waterproof layer 42 is constructed with polymer cement waterproof mortar or polymer cement waterproof coating, which plays a role in waterproofing and facilitating the smooth shaping of the concrete surface.
[0029] The interior of the coating layer 2 is coated with a rigid anti-bending part 5, and is used to enhance the anti-bending performance of the thermal insulation non-disassembly formwork. The rigid anti-bending part 5 is made of C-shaped steel. The number of the rigid anti-bending parts 5 is set to two, and they are symmetrically arranged on the same side of the vacuum insulation panel 1. By setting this number and method, a thermal insulation non-disassembly formwork with strong anti-bending performance can be obtained, and production costs can be saved; by adding C-shaped steel to the coating layer 2, the integrity of the coating layer 2 is enhanced after curing, and at the same time, the C-shaped steel can support the entire coating layer 2, thereby effectively improving the anti-bending performance of the thermal insulation non-disassembly formwork, and can reduce the breakage rate of the thermal insulation non-disassembly formwork during transportation and construction, while improving the quality of the thermal insulation non-disassembly formwork itself.
[0030] Example 2
[0031] The difference between Example 2 and Example 1 is that the rigid flexural member 5 is made of deformed steel bars, and other structures are the same; through the anti-bending test on the thermal insulation and non-removable formwork in Example 1 and Example 2, the anti-bending performances of the two are similar, and the cost of deformed steel bars is lower than that of C-shaped steel. Using deformed steel bars as the rigid flexural member 5 can not only ensure the anti-bending performance of the thermal insulation and non-removable formwork, but also reduce the production cost of the thermal insulation and non-removable formwork.
[0032] Example 3
[0033] The differences between Example 3 and Examples 1 and 2 are as follows: the position where the rigid flexural member 5 is arranged, and the number of the rigid flexural members 5 is more than two and symmetrically arranged on the front and rear sides of the vacuum insulation panel 1. Through this arrangement form of the rigid flexural member 5, the anti-bending performance of the thermal insulation and non-removable formwork can be further improved, which is applicable to buildings with high requirements for anti-bending performance.
[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
