Example Embodiment
[0039] Example one
[0040] reference figure 1 with figure 2 , The present invention provides a lightweight composite exterior wall panel, which is composed of a fiber-reinforced cement slab 2 and a load-bearing layer 1. The load-bearing layer 1 is a lightweight aggregate concrete layer reinforced by a double-layer steel mesh 3, with double-layer steel bars The net 3 is supported and connected by short steel bars 31. The two sides of the load-bearing layer 1 are compounded with fiber-reinforced cement slabs 2, and the load-bearing layer 1 has a cavity surrounded by lightweight aggregate concrete, which is filled with thermal insulation material 4 , The thermal insulation material 4 of this example is polystyrene foam board, and the middle part of this composite exterior wall panel has a five-layer structure: fiber-reinforced cement slab 2 + bearing layer 1 (built-in steel mesh 3) + thermal insulation material 4+ bearing layer 1 (with built-in steel mesh 3) + fiber-reinforced cem...
Example Embodiment
[0042] Example two
[0043] reference image 3 with Figure 4 , The present invention provides a lightweight composite exterior wall panel, its structure is basically the same as the first embodiment, the difference is that the double-layer steel mesh 3 is covered with cement and the short column steel 31 is diagonally supported and connected. This double-layer steel mesh There are two approaches:
[0044] 1. The cement-wrapped short column steel bar 31 is pre-made, the cement-wrapped short column steel bar 31 is connected with the double-layer steel mesh 3 into a whole, and the thermal insulation material 4 is sandwiched;
[0045] 2. Connect the short steel bars 31 without cement and the double-layer steel mesh 3 to form a whole, and at the same time sandwich the thermal insulation material 4, and reserve gaps at the thermal insulation material 4 through which the short steel bars 31 pass to allow these gaps When the wall panel is made, it is filled simultaneously with the concre...

[0046] Example three
[0047] reference Figure 5 with Figure 6 , The present invention provides a lightweight composite exterior wall panel, which is composited by a fiber-reinforced cement slab 2 and a load-bearing layer 1. The load-bearing layer 1 is a lightweight aggregate concrete layer reinforced by a steel mesh 3. A fiber-reinforced cement slab 2 is compounded on the side surface, and both ends of the load-bearing layer 1 are provided with tenons and grooves for easy assembly.
[0048] The concrete used to make the bearing layer 1 is a lightweight high-strength concrete composed of a mixture of cement, sand and lightweight aggregates. The lightweight aggregate used in the concrete is ceramsite. The cement used is preferably sulphoaluminate cement, or ordinary For Portland cement, the steel mesh 3 used is a double-layer steel mesh supported by wave steel bars 31.
[0049]When using this kind of wallboard, the side without the cement slab should be placed on the outer wall s...
