technical field

The invention relates to an assembled non-load-bearing reinforced concrete-aerated concrete composite wall panel process, which belongs to the field of building components.

Background technique

In the past, solid clay bricks were used for both load-bearing and non-load-bearing walls. With the issuance of notices to ban solid clay bricks in various provinces and cities, various new types of walls have gradually entered the construction market. The selection principles of non-load-bearing walls are: light weight, easy to obtain materials, sufficient resources; no masonry, no plastering, reduce or eliminate wet work; less structural area, easy to dismantle and change; good sound insulation, waterproof effect, and good durability , no cracking; simple construction, reasonable cost. However, the non-load-bearing walls currently on the market have disadvantages such as high cost, complicated construction technology, and easy cracking. Therefore, high-quality and low-cost non-load-bearing wall production technology is needed.

Contents of the invention

The object of the present invention is to provide an assembled prefabricated non-load-bearing ALC wall panel and its manufacturing and installation method. The invention can not only effectively solve the problems existing in the existing walls, but also has good thermal insulation and better heat insulation, meeting energy-saving standards; the holes make it have good sound insulation; good fire resistance, ALC board It is a non-combustible inorganic material; good frost resistance; good impermeability; factory production prefabrication, prefabricated dry installation; simple construction and low cost; good surface quality, no cracking; environmental protection; suitable for industrial buildings, civil buildings, etc. advantage. In addition, on the basis of ensuring the strength of the joints, it ensures the stability and safety of the wall outside the plane, and at the same time, through the rotatability of the wall panels in the plane, the wall has a follow-up that can adapt to large horizontal displacements in the plane. , with good shock resistance.

An assembled non-load-bearing reinforced concrete-aerated concrete composite wall panel.

The prefabricated non-load-bearing reinforced concrete-air-entrained concrete composite wall panel is composed of ALC board (1), reinforced concrete board (2), thermal insulation board (3), cement fiber concrete (4) and exterior wall paint in sequence from the inside to the outside. The outer structure is formed, and then the inner side of the wall is plastered with mortar, and the joints left are sealed with mortar (8).

A prefabricated non-load-bearing reinforced concrete-aerated concrete composite wall panel and its manufacturing and installation method are composed of the following processes:

a. First, fly ash (or silica sand), cement, lime, etc. are used as the main raw materials in the factory, and processed into a porous ALC board (1) through high-pressure steam curing, and the pre-set connecting bending ribs (5).

b. After the curing of the ALC (slab) is completed, the steel bars are bound together with the connecting bending bars (5) and concrete is poured, so as to process the reinforced concrete slab (2), so that the ALC slab (1) and the reinforced concrete slab (2) form a whole.

c. The insulation board (3) is also made in the factory, and is integrated with the reinforced concrete board (2) by connecting the bent bars (5).

d. Smear cement fiber concrete on the outside of the installed insulation board (3); then apply exterior wall paint on it to complete the wallboard production.

The thickness of the ALC board (1) of the assembled non-load-bearing reinforced concrete-air-entrained concrete composite wallboard is the same as that of the column (7). Evenly, set seams at the joints in the vertical direction of the columns; when the reinforced concrete slab (2), insulation board (3) and cement fiber concrete (4) are installed, also set seams at the center of the vertical columns, and the installation is complete Fill the joints with mortar (8) to make each component connected as a whole; on the vertical direction, the junction of each plate, that is, the adjacent place with the beam (6) plate, also establishes seams, and finally seals with mortar.

In the installation method of the assembled non-load-bearing reinforced concrete-aerated concrete composite wall panel, the assembled prefabricated ALC wall panel of the present invention is used for hanging the air-conditioning water heater washbasin, and the construction is simple and easy to handle.

In the installation method of the assembled non-load-bearing reinforced concrete-aerated concrete composite wall panel, the assembled prefabricated ALC wall panel of the present invention is installed on the periphery of the building, and can be connected with various steel structure frames as a non-load-bearing enclosure. parapet.

Detailed ways

As shown in Figure 1, the prefabricated non-load-bearing reinforced concrete-air-entrained concrete composite wall consists of ALC board (1), reinforced concrete board (2), thermal insulation board (3), cement fiber concrete (4) and exterior wall paint Construct from the inside to the outside, coat the inner side of the wall with mortar and plaster, and fill the joints with mortar (8) to seal the remaining joints.

A method for manufacturing an assembled prefabricated non-load-bearing ALC wall panel, comprising the following steps:

a. First, fly ash (or silica sand), cement, lime, etc. are used as the main raw materials in the factory, and processed into a porous ALC board (1) through high-pressure steam curing, and the preset connection bending ribs (5);

b. After the curing of the ALC (slab) is completed, the steel bars are bound together with the connecting bending bars (5) and concrete is poured, so as to process the reinforced concrete slab (2), so that the ALC slab (1) and the reinforced concrete slab (2) form a whole;

c. The insulation board (3) is also made in the factory, and is integrated with the reinforced concrete board (2) by connecting the bent bars (5);

d. Smear cement fiber concrete on the outside of the installed insulation board (3); then apply exterior wall paint to it to complete the wallboard production;
