Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A cast-in-place concrete layer 2 is movably provided on the top of the precast concrete slab 1, and square protrusions 3 are fixed on both sides of the bottom of the cast-in-place concrete layer 2, arc grooves 8 are opened on both sides of the top of the precast concrete slab 1, and anchor bolts 4 are fixedly inserted in the arc grooves 8, hidden beams 6 are provided around the inner wall of the precast concrete slab 1, and a polystyrene foam board 9 is provided in the middle of the hidden beam 6, a rock wool board 5 is provided on the top of the polystyrene foam board 9, and a special-shaped column 7 is fixed on the top of the rock wool board 5.

[0021] According to the attached Figure 2 As shown, the square protrusion 3 is movably inserted into both sides of the top of the precast concrete slab 1, and an anchor bolt 4 is fixedly arranged between the square protrusion 3 and the arc groove 8, so that the precast concrete slab 1 and the cast-in-place concrete layer 2 are tightly connected, reducing the risk of separation, making the overall volume fixed, and preventing the wall from cracking due to subsequent expansion.

[0022] According to the attached Figure 3 As shown, a hidden beam 6 is provided between the two groups of rock wool boards 5 and polystyrene foam boards 9 to increase the tightness of the connection between the boards, help reduce the propagation of sound through the gaps, improve the sound insulation effect of the building, and make the indoor environment quieter and more comfortable.

[0023] According to the attached Figure 4 As shown, two groups of rock wool boards 5 and polystyrene foam boards 9 are symmetrically arranged, and the two groups of rock wool boards 5 and polystyrene foam boards 9 are stacked up and down. The rock wool board 5 is an inorganic fiber material made from natural rock after high-temperature melting. It has excellent thermal insulation function, low thermal conductivity, and can effectively reduce the loss of heat energy. At the same time, it has excellent fire resistance and is a Class A non-combustible material. Even in high temperature or fire conditions, no toxic gas will be generated, thereby improving the safety and reliability of use. The polystyrene foam board 9 is a white object made of expandable polystyrene beads containing volatile liquid foaming agent, which is heated and pre-expanded in a mold and then heated to form. It has a fine closed-cell structural characteristic, has certain water absorption and compressive strength, and can meet the insulation needs of the building.

[0024] According to 3 and Attachment Figure 4 As shown, multiple groups of special-shaped columns 7 are arranged at equal intervals, and multiple groups of special-shaped columns 7 are fixedly arranged on the bottom end of the cast-in-place concrete layer 2 to increase the connection stability between the cast-in-place concrete layer 2 and the special-shaped columns 7, so that the plate structure fits more closely; During installation, temporary brackets 10, structural adhesive 11, adhesive 12 and elastic sealing material 13 are required to make the board more solid after installation and extend the service life of the board.

[0025] The temporary bracket 10 can be aligned with the control line to place the board, and also plays a supporting role for the placement of the board. The support point spacing of the temporary bracket 10 is 150CM, and 2-3 rows of brackets are set for each bay to improve the stability and support effect of the prefabricated thermal insulation composite board.

[0026] Structural adhesive 11 is used to fix the plate after it is in a suitable position for use. This can initially fix the plate in a suitable position to prevent the plate from being accidentally displaced or tipped over, and facilitate later fixation and qualitative treatment. Structural adhesive 11 is a high-strength adhesive material composed of polymer compounds. It has excellent bonding properties and durability, and can withstand high strength. It can firmly connect concrete, allowing concrete slabs and concrete to be more firmly connected to other connecting ends.

[0027] Adhesive 12 is used to fix two adjacent panels. An integrated thermal insulation composite panel is formed by combining a specific adhesive 12 and a mechanical fixing method. Adhesive 12 is applied between the precast concrete panel 1 and the cast-in-place concrete layer 2, as well as between every two adjacent panels and between the panels and other connecting ends. Adhesive 12 is made of natural materials, synthetic materials and inorganic materials, which can fill the tiny gaps between adjacent panels, improve the uniformity and strength of the joint surface, and enhance durability.

[0028] The elastic sealing material 13 is used to seal the joints between the plates. The elastic sealing material 13 is used after the adhesive 12 solidifies. The elastic sealing material 13 is applied to the surface of the adhesive 12. The elastic sealing material 13 is a material with good elasticity and sealing properties. It can effectively fill the gaps between the plates and reduce the gaps formed on the surface of the adhesive 12, effectively reducing the leakage of liquid or gas. It also has good elastic properties and can quickly return to its original state after being subjected to force, thereby maintaining stable sealing performance of the plate.

[0029] Working principle: put the whole in a suitable position, first place multiple groups of hidden beams 6 around the inner wall of the precast concrete slab 1 at one time, then place two groups of polystyrene foam boards 9 in the precast concrete slab 1 in sequence, then place the hidden beam 6 in the middle of the two groups of polystyrene foam boards 9, spread the rock wool board 5 on the top of the polystyrene foam board 9, so that the special-shaped column 7 is located at the top of the hidden beam 6, place multiple groups of anchor bolts 4 at the position of the arc groove 8, and finally pour concrete. The concrete flows into the precast concrete slab 1 and fills the hidden beam 6. After the concrete is poured, a cast-in-place concrete layer 2 and a square protrusion 3 are formed. The square protrusion 3 fixes the anchor bolt 4 at the arc groove 8. The surface of the multiple groups of special-shaped columns 7 is poured with concrete, so that the whole is cast and formed, and the precast concrete slab 1 and the cast-in-place concrete layer are fixed; During installation, clean the installation position to ensure that the foundation is flat and free of debris, accurately locate and mark according to the design drawings, align the temporary bracket 10 with the positioning and marking lines, place and fix it, and then use the lifting equipment to lift the panel to the temporary bracket 10, ensuring that its horizontality and verticality meet the requirements, and then fix the panel with the anchor bolts 4, use the structural adhesive 11 to preliminarily fix the four sides of the panel to the adjacent panel and the installation position, and then use the adhesive 12 to further fix the joints between the panels, and finally apply the elastic sealing material 13 between the panels for sealing. After the installation is completed, remove the temporary bracket 10 and conduct a comprehensive inspection of the installed thermal insulation composite panel.

[0030] The above is the entire working principle of the present invention.
