[0044] Preferably, the steel trough 3 is a galvanized steel trough.
[0045] Furthermore, the substrate 1 utilizes a sintered plate. Made from a variety of bulk industrial solid waste materials, including coal gangue, fly ash, oil shale slag, silt, red mud, boron mud, and mine tailings, these plates are vacuum extruded, dried, and sintered. They offer excellent sound insulation, thermal insulation, and durability. Specifically, the sintered plate is purchased directly from the market. Since this is prior art, its details are omitted for clarity.
[0046] In other embodiments, the substrate 1 may also be a hollow plate or other conventional plate material.
[0047] The spliced exterior wall panel is first produced in the factory to obtain a base plate 1 (see Figure 4-6 ) and steel channel 3 (see Figure 7-8), and then on-site construction and assembly.
[0048] The method for assembling the present embodiment is as follows:
[0049] S10, first fill the groove 1-2 of the first base plate 1 with adhesive slurry 5, then use the expansion bolt 2 to fix the steel groove 3 (expansion bolt 2 passes through the second connection hole 3-1) and the first base plate 1 (expansion bolt 2 passes through the first connection hole 1-3) and bond them together with the adhesive slurry 5 (see Figure 9-11 ); and the steel groove 3 in the groove 1-2 of the first substrate 1 is fixed to the ground, structural beam or building body by an anchor (not shown in the figure);

[0052] S40, connecting the third substrate 1 to the second substrate 1, and installing a rubber pad 4 between the boss 1-1 of the third substrate 1 and the steel groove 3 in the groove 1-2 of the second substrate 1. Then, the two plane gaps 1-4 between the third substrate 1 and the second substrate 1 are filled with insulation material 6 and sealant 7, and the insulation material 6 and sealant 7 are distributed inside and outside;
[0053] And so on.
[0054] This embodiment adopts splicing installation and uses concave and convex positioning to make the appearance flush, and the above-mentioned embodiment structure is used between the two substrates to achieve no ash seam, waterproof and heat insulation effect, no cracks, and can improve the life of the building (see Figure 1-2 and Figure 12-13 The utility model can realize the rapid construction of the exterior wall panels and avoid the influence of mortar joints; at the same time, it has the advantages of good workmanship, thermal insulation, no cracks, flushness, sealing, waterproofing and heat preservation.
[0055] In this embodiment, since the base plate is made of sintered material (sintered plate) which is a brittle material, steel grooves are provided at the grooves of the base plate to improve the overall strength of the wall panel and serve as installation anchoring points, while also playing the role of bonding and leveling.
[0056] In this embodiment, the base plate height can be made the same as the building floor height, and on-site installation does not require up-and-down splicing, but only left-and-right splicing.
[0057] In this embodiment, when two substrates are spliced together, the two plane seams 1-4 of the two substrates are filled with thermal insulation material 6 to prevent the generation of thermal bridges, and then the seams are caulked with sealant 7 to ensure waterproofing.

In this embodiment, the through holes 1-5 are distributed in three layers side by side, and the opening rate is greater than 50%. It is divided into an inner layer, a middle layer and an outer layer. Different functional materials can be set in the through holes 1-5 of the inner layer, the middle layer and the outer layer, so that a variety of combination effects can be achieved. For example, fireproof materials are set in a row of through holes 1-5 in the outer layer, sound insulation materials are set in a row of through holes 1-5 in the middle layer, and thermal insulation materials are set in a row of through holes 1-5 in the inner layer. In this way, flexible settings of different functions can be achieved to meet different needs. This embodiment utilizes the porous characteristics of the substrate to make the opening rate greater than 50%, which can not only reduce weight and cost, but also fill it with lightweight thermal insulation, sound insulation, fire resistance and other functional materials to improve the thermal insulation, sound insulation, fire resistance and other performance of the building.
