Detailed implementation manners

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] Please refer to together Figures 1 to 8, a fireproof, heat-insulating and heat-preserving composite wall panel provided by the present utility model will be described. The fireproof, heat-insulating and heat-preserving composite wall panel includes a wall panel body 1, the wall panel body 1 includes a polyurethane layer 11 and a rock wool layer 12 provided on at least one side of the polyurethane layer 11, and a support structure 13 is provided on the outer side of the wall panel body 1; wherein, slots 14 are provided at the top and one side of the wall panel body 1, and insertion protrusions 15 are provided at the bottom and the other side of the wall panel body 1; the wall panel body 1 can be spliced with an adjacent wall panel body 1, a telescopic joint 16 is left at the splicing position, and the telescopic joint 16 is sealed with aerogel; the rock wool layer 12 and the polyurethane layer 11 are adhesively cooperated.

[0033] Compared with the prior art, for the fireproof, heat-insulating and heat-preserving composite wall panel provided by the present utility model, the rock wool layer 12 has good fireproof performance; when the indoor and outdoor temperature difference is too large, there will be a deformation difference between the support structures 13 on both sides of the wall panel body 1. At this time, through the telescopic joint 16 between adjacent wall panel bodies 1, the support structures 13 inside and outside the wall panel body 1 can be compensated, and the situation of the wall panel bending and breaking can be reduced; the adjacent wall panel bodies 1 are inserted and cooperated through the insertion protrusions 15 and the slots 14, and the telescopic joint 16 is sealed with aerogel, which can solve the cold and heat bridge problem and make the composite wall panel have heat-preserving performance; the above wall panels of the present application are convenient for construction and assembly, and can meet the requirements of various types of buildings for the use functions of wall panels.

[0034] In some embodiments, as Figures 1 to 8 shown, the slots 14 and the insertion protrusions 15 of the wall panel body 1 are both provided on the polyurethane layer 11, and the insertion protrusions 15 are made of polyurethane; when the insertion protrusions 15 of the wall panel body 1 are inserted and cooperated with the slots 14 of another wall panel body 1, both sides of the insertion protrusions 15 are in contact with both sides of the slots 14, and an aerogel layer is provided between the end of the insertion protrusions 15 and the bottom of the slots 14.

[0035] It should be noted that the insertion protrusions 15 are integrally formed with the polyurethane layer 11. Through the above settings, adjacent two wall panel bodies 1 are spliced through the polyurethane layer 11 and then sealed with aerogel. After the construction is completed, the rock wool layers 12 on both sides of the polyurethane layer 11 can play a good heat-preserving performance, and together with the heat-preserving performance of the polyurethane layer 11 itself, the overall heat-preserving effect can be increased; the above splicing method can also strengthen the connection strength between adjacent two wall panel bodies 1.

[0036] In some embodiments, as Figures 1 to 8 shown, an aerogel heat-insulating coating 2 is provided on the support structure 13 located outdoors.

[0037] It should be noted that by providing the aerogel thermal insulation coating 2 outside the support structure 13, when sunlight shines on the composite wall panel, the aerogel thermal insulation coating 2 can achieve the effect of heat insulation, reduce the temperature rise of the support structure 13, and further reduce the temperature difference between the inner and outer support structures 13 of the composite wall panel, thereby reducing the expansion and contraction deformation of the composite wall panel.

[0038] In some embodiments, as Figures 1 to 8 shown, the aerogel thermal insulation coating 2 on the wall panel body 1 and the aerogel thermal insulation coating 2 of the adjacent wall panel body 1 form an avoidance space 17 at the position of the expansion joint 16; the composite wall panel further includes an elastic high-temperature resistant rubber strip (not shown in the figure), and the elastic high-temperature resistant rubber strip is installed in the avoidance space 17 between the wall panel bodies 1.

[0039] It should be noted that by providing the avoidance space 17 at the position of the expansion joint 16 of the aerogel thermal insulation coating 2, a buffer area can be provided for the deformation of the wall panel body 1; by providing the elastic high-temperature resistant rubber strip in the avoidance space 17, other sundries entering the avoidance space 17 can be reduced, and the aerogel between the expansion joints 16 can also be protected.

[0040] In some embodiments, as Figures 1 to 8 shown, the composite wall panel further includes a plurality of connecting nails 3, one end of each connecting nail 3 is connected to the polyurethane layer 11, and the other end of each connecting nail 3 is connected to the rock wool layer 12.

[0041] It should be noted that the connecting nails 3 can strengthen the connection between the polyurethane layer 11 and the rock wool layer 12. Before connecting the rock wool layer 12 to the polyurethane layer 11, a bonding layer is first provided on the rock wool layer 12, and then by pressing the rock wool layer 12 and the polyurethane layer 11, the rock wool layer 12 can be bonded to the polyurethane layer 11 to improve the connection strength.

[0042] In some embodiments, as Figures 1 to 8 shown, each connecting nail 3 includes an embedded rod 31 and a locking cap 32. One end of the embedded rod 31 is used for embedding in the polyurethane layer 11; the other end is used for plugging and mating with the rock wool layer 12; the plugging part of the embedded rod 31 has an external thread; the locking cap 32 has an internal thread; the locking cap 32 is in threaded cooperation with the embedded rod 31 to clamp the rock wool layer 12.

[0043] It should be noted that through the above setting method, after the rock wool layer 12 is installed on the polyurethane layer 11, by threading the locking cap 32 with the embedded rod 31, the rock wool layer 12 can be fixed on the polyurethane layer 11, and the connection strength between the rock wool layer 12 and the polyurethane layer 11 can be improved.

[0044] Exemplarily, a connection plate 33 can be provided at the position of the embedded rod 31 in the polyurethane layer 11. The connection plate 33 is fixed on the embedded rod 31. The connection plate 33 and the embedded rod 31 are embedded in the polyurethane layer 11 together, which can improve the connection strength between the embedded rod 31 and the polyurethane layer 11.

[0045] In some embodiments, as Figures 1 to 8 shown, each of the connecting nails 3 includes a sleeve 34 and a fastening bolt 35; the inside of the sleeve 34 has internal threads; one end of the sleeve 34 is used to insert into the rock wool layer 12 and the polyurethane layer 11; the insertion end of the sleeve 34 is provided with a diameter change; the diameter of the diameter-changing section of the sleeve 34 is smaller than the diameter of the sleeve 34; a deformation gap 341 is provided on the diameter-changing section; the fastening bolt 35 is in threaded cooperation with the sleeve 34; the threaded end of the fastening bolt 35 is used to laterally push against the diameter-changing section of the sleeve 34; the end of the diameter-changing section of the sleeve 34 has a convex protrusion 342, and when the fastening bolt 35 laterally pushes against the diameter-changing section, the protrusion 342 can laterally penetrate into the polyurethane layer 11.

[0046] It should be noted that first insert the sleeve 34 into the rock wool layer 12 and the polyurethane layer 11, and make the diameter-changing section of the sleeve 34 located inside the polyurethane layer 11; then screw the fastening bolt 35 into the sleeve 34, and make the threaded end of the fastening bolt 35 laterally push against the diameter-changing section of the sleeve 34, so that the diameter-changing section deforms outward. At this time, the protrusion 342 on the diameter-changing section can laterally penetrate into the polyurethane layer 11. Through the above setting method, the connection strength between the rock wool layer 12 and the polyurethane layer 11 can be improved.

[0047] Exemplarily, when fire protection is not required indoors, the rock wool layer 12 inside the wall panel body 1 can be removed (as Figure 3 and Figure 6 shown); when the composite wall panel is used as an indoor partition, the aerogel heat insulation coating 2 on the outside of the wall panel body 1 can be removed (as Figure 5 shown); as Figure 1 and Figure 4 shown, it is a schematic diagram when external heat insulation is required and internal fire protection is required; during the construction process, the joints between the wall panels can be set as horizontal joints or vertical joints according to actual needs.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
