Problems solved by technology

[0003] Under the impetus of national policies, great progress has been made in building interior wall materials, and many varieties of interior wall panels have appeared. However, in terms of exterior walls, because of their higher functional requirements, such as: Leakage, thermal insulation, sufficient strength for hanging heavy objects and anti-theft, and eliminating the impact caused by the large temperature difference between indoor and outdoor, etc., there are not many types of existing exterior wall panels, which cannot meet market demand

Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, a kind of lightweight composite exterior wall panel provided by the present invention is composed of fiber-reinforced cement slab 2 and load-bearing layer 1. The load-bearing layer 1 is a light aggregate concrete layer reinforced by steel mesh 3. The load-bearing layer 1 Fiber-reinforced cement slabs 2 are composited on both sides of the wall, and a cavity surrounded by lightweight aggregate concrete is left in the bearing layer 1. The cavity is filled with insulation materials 4. The middle part of this composite exterior wall panel is a five-layer structure : Fiber-reinforced cement slab 2+loading layer 1 (built-in steel mesh 3)+insulation material 4+loading layer 1 (built-in steel mesh 3)+fiber-reinforced cement slab 2, and its two ends are three-layer structure: Reinforced cement slab 2 + load-bearing layer 1 (built-in steel mesh 3 ) + fiber-reinforced cement slab 2, the two ends of the load-bearing layer 1 are set as tenon ...

Embodiment 2

[0041] Such as image 3 and Figure 4 As shown, a kind of lightweight composite exterior wall panel provided by the present invention is composed of fiber-reinforced cement slab 2 and load-bearing layer 1. The load-bearing layer 1 is a light aggregate concrete layer reinforced by steel mesh 3. The load-bearing layer 1 Fiber-reinforced cement slabs 2 are compounded on both sides of the bearing layer 1, and the two ends of the bearing layer 1 are set as tenons and tenons, which is convenient for assembly.

[0042] The concrete for making the load-bearing layer 1 is a lightweight high-strength concrete composed of cement, sand and light aggregate. The light aggregate used in the concrete is polyphenylene particle light aggregate. The cement used is preferably sulphoaluminate cement. Ordinary Portland cement can also be used, and the steel mesh 3 used is a double-layer steel mesh supported by steel bars.

Embodiment 3

[0044] A method for manufacturing a lightweight composite exterior wall panel as in Embodiment 1, comprising the following manufacturing process:

[0045] A. Place the prefabricated fiber-reinforced cement slabs 2 in parallel on both sides in each cavity of the wallboard molding machine;

[0046] B. Place the prefabricated double-layer reinforced mesh 3 supported by steel bars between two cement slabs 2, and pre-clamp the insulation material 4 between the double-layer reinforced mesh 3;

[0047] C. Pour light aggregate concrete between the two cement slabs 2 and between the cement slab 2 and the insulation material 4 to bury the reinforcement mesh 3, and at the same time, vibrate properly so that the light aggregate concrete fills the cavity in the cavity;

[0048] D. Stand for curing for a certain period of time, demoulding and stacking after the light aggregate concrete hardens.

Abstract

The invention provides a lightweight composite external wall panel and preparing method, which is composed of fabric reinforced cement flat and loading layer, wherein the loading layer is steel net reinforced light aggregate concrete layer; the fabric reinforced cement flat is composed on each side; the thermal insulation material is filled in the hollow cavity. The preparing method comprises the following steps: A. putting the fabric reinforced cement flat in the mould two sides; B. places the steel net with thermal insulation material in the middle between two fabric reinforced cement flats; C. pouring the light aggregate concrete among two fabric reinforced cement flats and thermal insulation material; D. waiting the mould demoulding to generate lightweight composite external wall panel.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight composite exterior wall panel and a manufacturing method thereof. Background technique [0002] The traditional wall material is clay bricks. The production of clay bricks not only destroys farmland, but also requires the use of coal and other fuels, which increases energy consumption. In order to save land resources, reduce energy consumption, and protect the ecological environment, the country has been actively promoting the reform of wall materials and building energy-saving policies. The Ministry of Construction mentioned in the "Outline of the Tenth Five-Year Plan for Building Energy Conservation of the Ministry of Construction" that "at present, the annual output of solid clay bricks in my country is still more than 540 billion pieces, most of which are caused by backward technology, waste of energy and pollution of the environment. 950,000 mu of arable land ...
