[0002] With the development of the construction industry and the continuous advancement of urbanization, high-rise buildings have become a symbol of urbanization. More and more high-rise and super-high-rise buildings are constantly emerging, and various formwork systems for these buildings have also emerged. At present, rock wool insulation boards are usually installed on the outside of building concrete walls. Rock wool insulation boards are a material specially designed and produced for the exterior insulation system of buildings. They are suitable for the exterior insulation of buildings with concrete or bricks as the main construction materials. It has the characteristics of non-combustion, non-heat and non-toxic gas release. When a fire occurs, it can effectively block the spread of fire and has very good fireproof performance. In addition, rock wool also has very good thermal insulation functions, which can make the house truly warm in winter and cool in summer, and reduce the consumption of air conditioning energy. At the same time, rock wool boards can also physically insulate and reduce noise, making the house quieter and more comfortable. The exterior wall rock wool insulation board provides effective protection for the building through its excellent fireproof, heat-insulating and sound-absorbing properties, and also improves the energy efficiency and living comfort of the building.

[0003] In the prior art, when constructing concrete exterior wall rock wool insulation boards, a wire mesh polystyrene board construction process is usually adopted. During the main body construction, the rock wool insulation board (with obliquely inserted steel wires) is cast together with the main body. However, there are many defects in the exterior wall and poor light perception, and there are obvious cold and hot bridges at the obliquely inserted steel wires. Binders and anchor bolts are also used to fix the exterior wall rock wool insulation boards. However, when constructing anchor bolts in this way, the quality of anchor bolt installation is difficult to control, and there is a problem that the exterior wall rock wool insulation board is not firmly fixed. The exterior wall rock wool insulation board is prone to falling off and hollowing, and the exterior wall is also prone to leakage. Summary of the invention
