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

[0039] refer to figure 1 and figure 2 , a lightweight composite exterior wall panel provided by the present invention, which is composed of a fiber-reinforced cement plate 2 and a load-bearing layer 1, the load-bearing layer 1 is a lightweight aggregate concrete layer reinforced by double-layer steel mesh 3, double-layer steel bars The net 3 is supported and connected by short steel bars 31. The two sides of the bearing layer 1 are compounded with fiber reinforced cement slabs 2. There is a cavity surrounded by light aggregate concrete in the bearing layer 1. The cavity is filled with thermal insulation material 4 , the thermal insulation material 4 of this example is a polystyrene foam board, and the middle part of this composite exterior wall panel is a five-layer structure: fiber-reinforced cement plate 2+bearing layer 1 (built-in steel mesh 3)+thermal insulation material 4+ load-bearing layer 1 (built-in steel mesh 3) + fiber-reinforced cement slab 2, and its two ends ar...

Embodiment 2

[0042] refer to image 3 and Figure 4 , a kind of lightweight composite exterior wall panel provided by the present invention, its structure is basically the same as the above-mentioned embodiment 1, the difference is that the double-layer steel mesh 3 uses cement to wrap the short-column steel bars 31 for oblique support connection, this double-layer steel mesh There are two approaches:

[0043] 1. Prepare the cement-wrapped short-column steel bar 31 in advance, connect the cement-wrapped short-column steel bar 31 with the double-layer steel mesh 3 to form a whole, and sandwich the thermal insulation material 4 at the same time;

[0044] 2. Use the short steel bars 31 without cement wrapping to connect with 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 where the short steel bars 31 pass through, so that these gaps When the wallboard is made, it is filled ...

Embodiment 3

[0046] refer to Figure 5 and Figure 6 , a lightweight composite exterior wall panel provided by the present invention, which is composed of a fiber-reinforced cement plate 2 and a load-bearing layer 1, the load-bearing layer 1 is a light aggregate concrete layer reinforced by a steel mesh 3, and one part of the load-bearing layer 1 Fiber-reinforced cement slabs 2 are composited on the sides, and the two ends of the bearing layer 1 are provided with tenons and grooves for easy assembly.

[0047] The concrete used to make the load-bearing layer 1 is lightweight high-strength concrete composed of cement, sand and light aggregate. The light aggregate used in the concrete is ceramsite, and the cement used is preferably sulphoaluminate cement. Ordinary Portland cement, the steel mesh 3 used is a double-layer steel mesh supported by corrugated steel bars 31.

[0048]When using this kind of wallboard, the side without the cement slab should be placed on the outer wall, and other f...

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.

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 ...
