[0027] It should be noted that the following detailed description is all exemplary, aims at providing further explanation to the utility model. Unless otherwise indicated, all technical and scientific terms used in this paper have the same meaning as that understood by ordinary skilled person in the technical field to which the utility model belongs.

[0028] The utility model will be explained in detail below in combination with the drawings, and the composite heat preservation formwork of vacuum heat insulation board disclosed in the embodiment is composed of multiple heat preservation units, such as Figure 1As shown, the heat preservation unit comprises a core material, which is arranged inside the reinforced steel wire mesh frame 2; wherein the core material comprises two parts, namely the vacuum heat insulation board 1 and the extruded polystyrene board 7. Specifically, two groups of vacuum heat insulation boards 1 are arranged inside one reinforced steel wire mesh frame 2, and the two groups of vacuum heat insulation boards 1 are separated by two extruded polystyrene boards 7. In this embodiment, each group of vacuum heat insulation boards 1 is composed of multiple small vacuum heat insulation boards, and in other embodiments, each group of vacuum heat insulation boards 1 can only use one whole vacuum heat insulation board.

[0029] As shown in Figure 1 An interface mortar layer 3 is arranged outside the reinforced steel wire mesh frame 2. In this embodiment, the interface mortar layer 3 is made outside the reinforced steel wire mesh frame 2 after the core material is installed into the reinforced steel wire mesh frame 2. It can be understood that when the interface mortar layer 3 is made, mortar is applied outside the reinforced steel wire mesh frame 2 respectively, and finally the interface mortar layer 3 formed will wrap the reinforced steel wire mesh frame 2; the interface mortar layer and the reinforced steel wire mesh frame 2 are jointly consolidated into a protective layer, which can protect the vacuum heat insulation board 1 inside the reinforced steel wire mesh frame 2 and reduce the damage rate of the vacuum heat insulation board during transportation or installation.

[0030] As shown in Figure 2 The reinforced steel wire mesh frame 2 comprises upper and lower horizontal steel wire meshes of the same size, and two side vertical steel wire meshes and one middle vertical steel wire mesh are arranged between the upper and lower horizontal steel wire meshes. Specifically, the long edges of the upper and lower horizontal steel wire meshes are aligned, and then one side vertical steel wire mesh is welded between the two long edges of the two horizontal steel wire meshes respectively, thereby obtaining a hollow cuboid; then the middle vertical steel wire mesh is welded between the midlines of the wide edges of the two horizontal steel wire meshes, so that two hollow cuboids of the same size are formed inside the reinforced steel wire mesh frame 2.

[0031] In this embodiment, the size of the hollow cuboids formed inside the reinforced steel wire mesh frame 2 is 3-5mm larger than the size of the core material, which is designed in this way because the core material needs to be arranged inside the reinforced steel wire mesh frame 2 first, and then the mortar is applied to prepare the interface mortar layer 3, so as to ensure that the interface mortar layer 3 can wrap the reinforced steel wire mesh frame 2, which is convenient for production and subsequent processing. In this embodiment, the steel wire mesh is a hot-dipped galvanized welded mesh, which can ensure the durability of the product.

[0032] It should be noted that the middle vertical steel wire mesh is fixedly connected with a plurality of binding members 6, which are used to connect the heat preservation unit with the reinforced mesh frame of the wall to be poured. In this embodiment, the binding member 6 is a steel isosceles right triangle frame, the long edge of the triangle frame is fixedly connected with the middle vertical steel wire mesh, and the use of the isosceles right triangle frame not only saves materials, but also has better stability.

[0033] like Figure 1 As shown, an insulating mortar transition layer 4 is provided on the outside of the interface mortar layer 3 on the side where the binding member 6 is located, and a finishing layer 5 is provided on the outside of the insulating mortar transition layer 4; a finishing layer 5 is also provided on the outside of the interface mortar layer 3 on the opposite side of the binding member 6. The function of the insulating mortar transition layer 4 is as follows: the core material and the cast-in-place concrete have significantly different properties, and when the environment changes drastically, their deformations are not synchronized, easily leading to cracking, peeling, etc. The insulating mortar transition layer, located between the two, serves as a transition layer. The finishing layer 5, made of finishing mortar, further enhances the protective function.

[0034] like Figure 1 As shown, inside the reinforced steel wire mesh frame 2, an extruded polystyrene board 7 is installed on both sides of the central vertical steel wire mesh; then, a set of vacuum insulation panels 1 is installed between the extruded polystyrene board 7 and the side vertical steel wire mesh. The extruded polystyrene board 7, as an insulation material, also serves to protect the vacuum insulation panel 1 in this embodiment. Specifically, in this embodiment, relying solely on the binding members 6 to connect the insulation unit to the wall steel mesh frame is insufficient to create an effective fixation between the insulation unit and the wall; however, by installing the extruded polystyrene board 7 and passing tie bolts through it, the insulation unit is connected and fixed to the inner template, making the insulation unit act as the outer template, thus strengthening the connection between the insulation unit and the wall steel mesh frame; effectively avoiding damage to the vacuum insulation panel 1 caused by passing tie bolts.

[0035] In this embodiment, the insulation unit is pre-fabricated in the factory. Therefore, according to the on-site construction requirements, multiple tie rod holes are pre-drilled in the extruded polystyrene board 7. When preparing the interface mortar layer 3, plugs can be placed in the tie rod holes to prevent mortar from clogging them. The plugs should also be higher than the interface mortar layer 3, thus forming multiple tie rod holes in the interface mortar layer 3 as well. The tie rod holes are used to pass through the tie rod bolts. This arrangement facilitates direct on-site construction and avoids potential damage to the interface mortar layer 3 caused by drilling during on-site construction. It is understood that the number of tie rod bolts is not limited here and is determined according to the specific construction requirements.

[0036] The vacuum insulation panel composite insulation template without disassembly in this embodiment also includes a dedicated connector 8, which connects two adjacent insulation units together. Specifically, as shown in the example... Figure 3As shown, the special connector 8 is welded from two parallel horizontal steel plates, one vertical steel plate, and multiple serrated steel plates. In this embodiment, two serrated steel plates are provided, located at the top ends of the vertical steel plate. It is understood that in other embodiments, the number of serrated steel plates can be three, five, or more. The serrated steel plates have serrations on two opposite sides and non-serrated edges on the other two sides. During fabrication, the vertical steel plate is welded and fixed between the center lines of the two horizontal steel plates to form an "I"-shaped component. Above one of the horizontal steel plates, the non-serrated edges of multiple serrated steel plates are welded and fixed. The multiple serrated steel plates are evenly distributed on the horizontal steel plates, and the vertical steel plate and the serrated steel plates are on the same plane.

[0037] In this embodiment, the length of the vertical steel plate in the special connector 8 is equal to the length of the insulation unit, the width of the vertical steel plate is equal to the thickness of the insulation unit, and the width of the horizontal steel plate is 20 cm. This allows the special connector 8 to accommodate the insulation unit and to be installed along the length of the insulation unit, preventing grout leakage during concrete pouring. Two insulation units are respectively placed on both sides of the special connector 8, and then the serrated steel plate of the special connector 8 is positioned towards the wall reinforcement mesh, with multiple serrated steel plates placed between the upper and lower horizontal bars of the wall reinforcement mesh. The serrated edges of the serrated steel plates can hold the reinforcing bars in the wall reinforcement mesh, facilitating connection with the wall reinforcement mesh. By using the special connector 8, the assembly sealing between insulation units can be improved, preventing grout leakage during concrete pouring, and further improving the connection strength between the insulation unit and the wall reinforcement mesh. It is understandable that the distance between the two serrated edges of the serrated steel plate is equal to the distance between the upper and lower horizontal bars in the wall steel reinforcement mesh, and the distance between the two non-serrated edges is equal to the thickness of the wall steel reinforcement mesh; the serration of the serrated steel plate is greater than the diameter of the horizontal bars in the wall steel reinforcement mesh.

[0038] In this embodiment, by setting an enhanced steel wire mesh frame 2 and an interface mortar layer 3 on the outside of the core material, the core material is protected, which can reduce the damage rate of the vacuum insulation board during transportation or installation; by setting a binding piece 6 and a special connector 8 to connect with the wall steel mesh frame, and by setting an extruded polystyrene board 7 to connect with the inner template through tie bolts, the effective fixation between the vacuum insulation board and the wall is strengthened.

[0039] It is understandable that tie bolts are existing technology and are widely used in the connection of templates. In this embodiment, during connection, one end of the tie bolt is located on the side of the inner template away from the insulation unit, and the other end is located on the side of the insulation unit away from the inner template. Long steel pipes are provided at the ends of adjacent tie bolts. The steel pipes are located between the ends of the tie bolts and the inner template or the insulation unit. The tie bolts connect the inner template and the insulation unit through the long steel pipes.

[0040] The utility model discloses above although the specific embodiment of the utility model has been described in conjunction with the drawing, is not the limit to the protection scope of the utility model, and the person skilled in the art should understand that on the basis of the technical scheme of the utility model, various modifications or deformation that the person skilled in the art can make without paying creative labour are still within the protection scope of the utility model.
