[0022] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] This embodiment provides a technical solution: a composite wall based on an integrated insulation structure board, such as Figure 1-2As shown in the figure, it includes two primary structures and a secondary structure. The secondary structure is arranged between the two primary structures. The primary structure is a load-bearing part, which is a prefabricated product in the factory and is transported to the construction site for installation.

[0025] The primary structure includes a concrete wall 1, a steel reinforcement cage 2, a plurality of support and fixing standard parts 3, and an external composite insulation board 4. The steel reinforcement cage 2 and the plurality of support and fixing standard parts 3 are both arranged inside the concrete wall 1. The steel reinforcement cage 2 is used to enhance the support performance of the concrete wall 1. The support and fixing standard parts 3 are laid and fixed on the well-tied steel reinforcement cage 2 before pouring concrete, and are used to support and fix the formwork. The external composite insulation board 4 is laid on the wall of the concrete wall 1, and the external composite insulation board 4 is fixed to the support and fixing standard parts 3 and connected by through-wall bolts, and tightened with screws on the inner and outer sides of the wall respectively. There are 5 extended anchor bolts per square meter on the insulation board 4. The extended anchor bolts pass through the insulation board 4 and are fixed to the steel reinforcement cage with binding wire. After pouring concrete, the insulation board 4 combines with the concrete, and the extended anchor bolts are embedded in the concrete and cannot be pulled out.

[0026] The two external composite insulation boards 4 at the corner of the concrete wall 1 are tenoned and butted. The specific butting method is as follows: The ends of the two external composite insulation boards 4 at the corner of the concrete wall 1 that are close to each other are both inclined surfaces, and the inclination angles of the inclined surfaces are both 45°. The inclined surfaces are provided with a groove part 41 and a convex part 42 along their length directions, and the groove part 41 and the convex part 42 on the two external composite insulation boards 4 are butted with each other. The two external composite insulation boards 4 are firmly combined by tenon and mortise joints, and it is not easy to bulge the formwork during concrete pouring, and the external composite insulation board 4 is perfectly combined with the entire concrete structure.

[0027] The support and fixing standard part 3 includes a connecting rod and discs fixed at both ends of the connecting rod. The diameter of the disc is larger than the diameter of the connecting rod. The diameter of the disc is 10 cm, and the end faces of the two discs are respectively in the same plane as the two sides of the concrete wall 1, so that the cross-sections at both ends of the cushion block become larger, solving the problem of the formwork sinking inwards and reducing the flatness error of the wall surface after pouring.

[0028] Embodiment 2

[0029] This embodiment is further optimized on the basis of the above embodiment. The same parts as the foregoing technical solutions will not be described herein again. As Figure 3 As shown in the figure, in order to better implement the present invention, the following setting method is particularly adopted: In this embodiment, the secondary structure includes an internal composite insulation board 5 and a concrete filling 6. The internal composite insulation board 5 is provided with a through-type communication cavity 51, that is, the internal composite insulation board 5 is in a hollow shape. The concrete filling 6 is laid on both sides of the internal composite insulation board 5 and in the communication cavity 51. The concrete filling 6 forms an integral body with the internal composite insulation board 5, and the inner and outer layers of concrete are connected through, effectively solving the problem of the insulation layer falling off.

[0030] Furthermore, the communicating inner cavity 51 includes a vertical portion and a plurality of transverse portions communicating with the vertical portion. In this embodiment, there are three transverse portions, that is, the communicating inner cavity 51 as a whole is a "丰"-shaped structure.

[0031] Furthermore, the inner composite insulation board 5 is made of EPS material.

[0032] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive.
