[0002] Rock wool board is also called rock wool insulation decorative board, which is an inorganic fiber board made of basalt as main raw material through high-temperature melting processing. It is a new type of thermal insulation, fireproof and sound-absorbing material, with the characteristics of light weight, small thermal conductivity, heat absorption and non-combustibility.

[0003] Rock wool board is usually used as external wall insulation material. Currently, during construction, it is fixed to the wall by using adhesive or nailing. However, using these installation methods can cause damage to the rock wool board during disassembly, which is not conducive to the reuse of rock wool board and wastes resources and costs. In addition, rock wool board is a soft material with good elasticity, and it lacks support. When nailing directly penetrates the rock wool board, it can cause the nailing part of the rock wool board to sink, affecting the surface flatness and the firmness of the connection, which is not conducive to subsequent external wall construction. Furthermore, the current rock wool board lacks the function of connecting multiple pieces, and the overall firmness is insufficient. SUMMARY

The support grid is provided with multiple positioning blocks. The positioning blocks are inserted into the grid holes of the support grid. The grid holes of the support grid are square structures. The support grid is composed of longitudinally and transversely distributed connecting strips. The positioning blocks are respectively provided with sleeve inserts on the front and back sides. The sleeve inserts are inserted into the connecting strips adjacent to the front and back sides of the positioning blocks. The positioning blocks are provided with mounting holes penetrating in the up-down direction. Wall fixing bolts are inserted into the mounting holes. The positioning blocks are provided with positioning screw holes penetrating in the left-right direction on the side. Locking bolts are screwed into the positioning screw holes. When the positioning blocks are inserted into the grid holes of the support grid, the positioning screw holes are above the support grid.

[0006] Further optimization of the technical scheme is that the positioning blocks of the composite rock wool board are provided with multiple grout holes penetrating in the up-down direction.

[0007] Further optimization of the technical scheme is that the rock wool board body of the composite rock wool board is filled with an aluminum alloy reinforcing plate in the middle.

[0008] To further optimize the technical solution, a countersunk hole is opened on the upper side of the installation hole of a composite rock wool board; the countersunk hole corresponds to the screw head of the wall fixing bolt.

[0009] The beneficial effects of the present invention are:

[0010] 1. A supporting grid is bonded and fixed to the upper surface of the rock wool board body. The mesh holes of the supporting grid can provide a supporting position for the installation of the positioning block. Moreover, the support of the rock wool board body by the supporting grid can improve the surface deformation resistance of the rock wool board body and improve the protective effect of the rock wool board body on the exterior wall after it is positioned on the exterior wall. In addition, the mesh holes on the supporting grid can also improve the firmness of the mortar when applying mortar on the exterior wall.

[0011] 2. The positioning block is provided with mounting holes along the up and down directions, and wall fixing bolts are inserted into the mounting holes. The wall fixing bolts can penetrate the rock wool board body to achieve connection with the wall; by plugging the positioning block into the mesh holes on the supporting grid, the installation position of the wall fixing bolts relative to the rock wool board body can be determined, which facilitates passing the wall fixing bolts through the rock wool board body in advance.

[0012] 3. The support of the positioning block on the wall bolts and the support of the connecting strip on the supporting grid on the sleeve can avoid the problem of local depression caused by direct pressure of the wall bolts on the rock wool board body when the rock wool board body is connected to the wall through the wall bolts, thereby improving the surface flatness and connection firmness of the rock wool board body after installation.

[0013] 4. Positioning screw holes are opened on the side of the positioning block in the left and right directions. The inner threads of the positioning screw holes are connected with locking bolts. The mesh holes on the supporting grid are square structures. Through the locking bolts, they can be connected with the positioning blocks on the other adjacent rock wool board bodies to achieve the effect of splicing and connecting multiple rock wool board bodies, thereby improving the overall firmness of multiple rock wool board bodies after the erection operation.
