Abstract

The invention relates to a lightweight compounded outer wallboard and the manufacturing method thereof. And it is compounded of fiber or wire fabric reinforced cement slab and bearing layer, where the bearing layer is made of reinforcing fabric reinforced light aggregate concrete, one or two sides of the bearing layer are combined with cement slabs and a cavity in the bearing layer is enveloped by light aggregate concrete and full of heat insulator. And its manufacturing method comprises a process as follows: A. placing cement slabs on one or two sides in a die space; B. placing reinforcing fabric provided with heat insulator in the middle by the cement slabs in the die space; C. pouring light aggregate concrete in the die space to bury the reinforcing fabric; and D. staying, curing and hardening and then demoulding to make it. And the method is simple, practical, high-efficiency and it has advantages of lightweight, high intensity, strong bearing capacity, good heat insulating property, seismic resistance, seepage prevention, etc.

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 cement slab 2, and its two ends have a three-layer structure: fiber-reinforced cement slab 2+ bearing layer 1 (with built-in steel mesh 3) + fiber-reinforced cement The two ends of the flat plate 2 and the bearing layer 1 are provided with tenons and grooves for easy assembly.
[0041] The thermal insulation material 4 is preferably a polystyrene foam board, and light materials such as mineral wool board or rock wool board can also be used. The concrete used to make the bearing layer 1 is made of cement, sand (and crushed stone if necessary) and light Lightweight high-strength concrete mixed with aggregates, etc. The light aggregates used in the concrete are inorganic light aggregates such as ceramsite or expanded perlite. The cement used is preferably sulfoaluminate cement, or ordinary Portland cement. The double-layer steel mesh 3 used can also be wave-type steel support or diagonal steel support. The thermal insulation material 4 is sandwiched between two layers of steel mesh. Between 3.

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 concrete of the load-bearing layer, and the short steel bars 31 become cement-wrapped short column steel bars.

Example Embodiment

[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.
