[0015] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0016] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "length", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0018] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0019] As Figures 1 to 4 shown, a super-low energy consumption building exterior wall thermal insulation system includes a base wall 1, an anchor 2, a vacuum adiabatic thermal insulation board 3, a protective surface layer 4 and a decorative surface layer 5 which are connected in sequence from inside to outside. An expansion anchor bolt 25 is arranged on one side of the anchor 2 facing the base wall 1. The expansion anchor bolt 25 is inserted into the base wall 1 and fixed to realize the installation of the anchor 2 and the base wall 1. A first clamping member is arranged on one side of the anchor 2 facing the vacuum adiabatic thermal insulation board 3, and a second clamping member is arranged on one side of the vacuum adiabatic thermal insulation board 3 facing the anchor 2. The numbers of the first clamping member and the second clamping member are both multiple and are arranged correspondingly. The first clamping member and the second clamping member at corresponding positions are clamped with each other, thereby completing the positioning and connection of the vacuum adiabatic thermal insulation board 3 and the anchor 2. Preferably, the first clamping member is a clamping groove 22, and the second clamping member is a convex block 31. The convex block 31 corresponds to the shape of the clamping groove 22, and the convex block 31 is embedded in the clamping groove 22. For the convenience of installation, both the convex block 31 and the clamping groove 22 are of cylindrical structures.

[0020] Preferably, the shape of the anchor plate 21 is X-shaped, and the expansion anchor bolt 25 is arranged at the center of the X-shaped anchor plate 21 and penetrates through the anchor plate 21, so that the anchor plate 21 is convenient for installation and has a high installation strength.

[0021] Since the first clamping member and the second clamping member are in one-to-one correspondence and cooperate with each other, it is necessary to strictly control the installation angle of the anchor plate 21. A bubble level 24 is arranged on the anchor plate 12. The bubble level 24 can be arranged between adjacent extended ends of the anchor plate 21 and will not affect the subsequent installation of the vacuum adiabatic thermal insulation board 3.

[0022] An easy-to-tear strip 23 is arranged between adjacent first clamping members of the anchor plate 21, so that the size and shape of the anchor plate 21 can be cut according to actual needs, and the anchor 2 is suitable for vacuum adiabatic thermal insulation boards 3 of different sizes and shapes.

[0023] The anchor plate 21 is made of high-density polyurethane material, so that it has good heat insulation performance.

[0024] The installation steps are as follows:

[0025] (1) Mark lines on the base wall 1 to determine the installation positions of the vacuum adiabatic insulation boards 3, and further determine the anchoring positions of the anchor fittings 2;

[0026] (2) Install the expansion anchor bolts 25 in the base wall 1 and fix them to complete the installation of the anchor fittings 2;

[0027] (3) Mate and connect the second engaging members on the vacuum adiabatic insulation boards 3 with the first engaging members on the anchor plates 21 to complete the installation of the vacuum adiabatic insulation boards 3;

[0028] (4) Apply plastering mortar on the outer layer of the vacuum adiabatic insulation boards 3 and press alkali-resistant fiberglass mesh cloth into it to complete the installation of the protective surface layer 4;

[0029] (5) Conduct coating construction to complete the finishing layer 5.

[0030] The above has described the present utility model by way of example, but the present utility model is not limited to the above specific embodiments. Any modification or variation based on the present utility model falls within the scope of protection required by the present utility model.
