[0003] However, there are still the following problems with the prefabricated building exterior wall panels on the market:

[0004] (1) The volume of PC exterior wall panels is very heavy, and the problem of self-weight makes construction difficult.

[0005] (2) Because the gaps between PC walls cannot be 100% sealed, when too much rainwater accumulates, the water will flow upward along the wall joints and seep into the house. This shows that the current PC wall structure design system is imperfect and has weak waterproof performance.

[0006] (3) Due to the installation deviation, the fit of the concrete wall hoisting is low, and the position needs to be adjusted manually in the later stage. Due to its huge size, it is extremely difficult to hoist the wall panels at high altitude into the corresponding groove position.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The present embodiment provides an assembled steel-aluminum composite structural exterior wall panel, which includes a plurality of prefabricated unit panels, and the plurality of unit panels are assembled into one in horizontal and vertical directions.

[0042] Each unit plate includes a plate body, a steel member for bearing force, and an aluminum alloy member for waterproof connection. One side of the steel member is fixedly connected to one side of the wall panel, and the other side of the steel member is fixedly connected to one side of the aluminum alloy member. The other side of the aluminum alloy member is provided with a splicing part, and the splicing part has a concave-convex structure, and the concave-convex structure includes convex strips and grooves.

[0043] See also Figure 1 and Figure 2 , the two adjacent unit plates on the left and right are assembled through the vertical joint node. The structure is described from left to right. The vertical joint node includes a first steel member 1, a first aluminum alloy member 2, a second aluminum alloy member 3 and a second steel member 4. The first steel member 1 is connected to the plate body 100 on the left side by screws, and the first aluminum alloy member 2 is connected to the first steel member 1 by screws. The second aluminum alloy member 3 is connected to the second steel member 4 by screws, and the second steel member 4 is connected to the plate body 100 on the right side by screws.

[0044] The first aluminum alloy component 2 is provided with a first splicing portion on the right side thereof, and the first splicing portion has a first concave-convex structure, and the first concave-convex structure includes a first convex strip 21 and a first concave groove 22. The second aluminum alloy component 3 is provided with a second splicing portion on the left side thereof, and the second splicing portion has a second concave-convex structure, and the second concave-convex structure includes a second convex strip 31 and a second concave groove 32.

[0045] The first convex strip 21 is provided with a first vertical receiving groove 211, and a first waterproof rubber strip a is embedded in the first vertical receiving groove 211. The first waterproof rubber strip a has an extended end extending out of the first vertical receiving groove 211, and the extended end extends into the gap between the first convex strip 21 and the second convex strip 31 (i.e., the groove wall of the second groove 32). Similarly, the second convex strip 31 of the second aluminum alloy component 3 is provided with a second vertical receiving groove 311, and a second waterproof rubber strip b is embedded in the second vertical receiving groove 311. The second waterproof rubber strip b has an extended end extending out of the second vertical receiving groove 311, and the extended end extends between the first convex strip 21 and the second convex strip 31.

[0046] Specifically, Figure 1 As shown, the first aluminum alloy component 2 has two first convex strips 21, and the second aluminum alloy component 3 has two narrower second grooves 32 and one wider second groove 32. The two first convex strips 21 are respectively embedded in the two narrower second grooves 32, and a water-stopping sponge e is embedded between the bottom of the narrower second groove 32 and the end of the first convex strip 21.

[0047] The first aluminum alloy component 2 is provided with a first sealed cavity at one end close to the outer side surface of the plate body 100, and the second aluminum alloy component 3 is provided with a second sealed cavity at one end close to the outer side surface of the plate body 100, and a gap is formed between the first sealed cavity and the second sealed cavity. The outer wall of the first sealed cavity is provided with a first vertical receiving groove 211, and the third water-stopping rubber strip c is embedded in the first vertical receiving groove 211, and the protruding end of the third water-stopping rubber strip c is ring-shaped, and the protruding end extends into the gap. Similarly, the outer wall of the second sealed cavity is provided with a second vertical receiving groove 311, and the fourth water-stopping rubber strip d is embedded in the second vertical receiving groove 311, and the protruding end of the fourth water-stopping rubber strip d is also ring-shaped and extends into the gap. It can be seen that the protruding ends of the third water-stopping rubber strip c and the fourth water-stopping rubber strip d are close together to form a sealed gap structure.

[0048] Furthermore, a vertical seam shielding member 5 is provided at one end of the gap near the outer side of the plate body 100, and the vertical seam shielding member 5 is mounted on the first aluminum alloy member 2 or the second aluminum alloy member 3 by snap-fitting. The vertical seam shielding member 5 can prevent the gap from being exposed and affecting the appearance of the exterior wall.

[0049] This embodiment sets vertical seam nodes to assemble and splice the left and right unit plates. This design has three nodes to block rainwater. If rainwater washes the exterior wall and accidentally passes through the first node, part of the water will flow down longitudinally along the geocentric stress, and the rest will enter the second node in a straight direction. There are two blocking points at the bend. When it reaches the hollow, the water will flow vertically downward from the beginning and reach the bend of the third node. There are also two blocking points at the bend. It can be seen that after the rainwater enters the first node, it needs to bypass two nodes to enter the house, and the probability is almost zero. Therefore, this design has strong waterproof ability and no high-altitude seam filling operation is required in the later stage.

[0050] See also Figure 3 , two unit plates adjacent to each other are assembled through a horizontal seam node. The horizontal seam node includes a third steel member 6, a third aluminum alloy member 7, a fourth aluminum alloy member 8 and a fourth steel member 9 arranged in sequence from top to bottom. The third aluminum alloy member 7 is connected to the third steel member 6 by screws, and the fourth aluminum alloy member 8 is connected to the fourth steel member 9 by screws.

[0051] The bottom surface of the third aluminum alloy component 7 is provided with a third splicing portion, the third splicing portion has a third concave-convex structure, and the third concave-convex structure includes a third convex strip 71 and a third concave groove 72. The top surface of the fourth aluminum alloy component 8 is provided with a fourth splicing portion, the fourth splicing portion has a fourth concave-convex structure, and the fourth concave-convex structure includes a fourth convex strip 81 and a fourth concave groove 82.

[0052] The third convex strip 71 is located at one end of the third aluminum alloy component 7 close to the outer side surface of the plate body 100, and a third transverse receiving groove 711 is arranged at the top of the third convex strip 71. A fifth water-stopping rubber strip e is embedded in the third transverse receiving groove 711, and the fifth water-stopping rubber strip e has an extending end extending out of the third transverse receiving groove 711, and the extending end is arc-shaped. The arc-shaped extending end extends into the gap between the upper and lower plate bodies 100, so as to prevent rainwater from entering the gap between the upper and lower plate bodies 100.

[0053] Furthermore, the fourth aluminum alloy component 8 is provided with an aluminum alloy water strip f at one end close to the outer side of the plate body 100, and the cross section of the aluminum alloy water strip f is L-shaped. The fourth aluminum alloy component 8 is provided with an aluminum alloy water stop slider g at one end close to the inner side of the plate body 100 (i.e., in the fourth groove 82).

[0054] In summary, please refer to Figure 4 and Figure 5 In this embodiment, steel components are respectively arranged on the four sides of the plate body 100 as load-bearing members, and aluminum alloy components are arranged as waterproof components, thereby achieving the invention purpose of making the exterior wall panel material light and easy to hoist.

[0055] The plate body 100 of this embodiment may be a glass plate or a composite plate. Figure 1 and Figure 2 FIG. 1 is an example of a composite panel, which includes an exterior panel 101, a filling layer 102 and an interior panel 103 arranged in sequence from the outside to the inside. Preferably, the filling layer 102 may be rock wool, polyurethane or glass wool.

[0056] See also Figure 6 and Figure 7 The installation steps of the above-mentioned assembled steel-aluminum composite structure exterior wall panels are as follows:

[0057] S1. Use the prefabricated lifting ring on the unit plate to lift the unit plate;

[0058] S2. Lift the unit panel to the top of the location where it needs to be installed;
