Description

Prefabricated non-load-bearing cast-in-place lightweight composite wall

technical field

The utility model belongs to the construction field, in particular to an assembled non-load-bearing cast-in-place lightweight composite wall.

Background technique

At present, the wall structure forms commonly used in the construction field are: 1. Pouring concrete wall: the concrete density of this kind of wall is 2300kg/m3, because of the high bulk density of raw materials, the weight of the formed wall is high, which increases the weight of the building , resulting in a large amount of steel used in the building, which increases the construction cost. At the same time, it is found through engineering applications that the wall also has poor sound insulation effect, and the wall is complicated to deal with in the decoration. The wall after decoration is easy to peel and fall off, etc. ;

2. Aerated block masonry wall: This kind of wall is not easy to hang heavy objects, which brings troubles to users in the later installation of air conditioners. The reason is that the raw materials and process factors of the product cause the aerated concrete block itself The texture is soft; in addition, this kind of wall cracks, peels, and falls off. During the production and maintenance of the concrete block, the water inside the surface evaporates, and excessive water loss causes shrinkage. The secondary hydration reaction during masonry makes the block The volume expands, which makes the wall crack, and after the blocks are formed, the wall needs to be leveled and plastered. Due to the incompatibility between the properties of the blocks and the properties of the plastering mortar, the wall cracks and the surface layer peels off; There is also poor sound insulation performance of this kind of wall: the gaps formed by the construction process of the blocks during masonry and other factors lead to poor sound insulation performance of the wall, and there are many construction procedures, which are difficult and difficult to control, and the integrity of the wall is poor. The disadvantage of adding blocks.

3. Prefabricated lightweight wallboard wall: This kind of wall has many construction procedures, high cost, poor overall firmness of the wall, poor sound insulation performance, cracking of seams and other shortcomings; the reason is that the specification of the wallboard is 2.4 meters × The main specification is 0.6 meters. The walls of the building walls are generally 2.8 meters high and more than 2 meters wide. Due to the size constraints, the construction of light wallboard walls will be cumbersome during splicing. The size of the wall Inconsistency makes it easy to cause loss during splicing, generate construction waste, and increase construction costs. Too many splicing seams will make the overall firmness of the wall poor, and it is difficult to control the flatness of the wall during construction.

The most difficult problem to solve is the cracking of the joints of lightweight wall panels. The joints of conventional lightweight wall panels are made of glass fiber mesh cloth, but Portland cement or water-resistant putty and glass fiber mesh cloth There will be a chemical reaction, which will swell when it meets water, which will reduce the bond between the slats and cause the wall to crack. At the same time, due to the slow chemical reaction, it has strong concealment. After a period of time, the wall will absorb water or be damp. Hollow cracking, such cases are not uncommon in light-weight wallboard walls, which is a common problem in light-weight wallboard walls.

Whether it is aerated concrete block walls or lightweight wall panels, they are all in the way of "production, supply, and sales". They are prefabricated in the factory, and then the finished products are transported to the construction site, and the secondary construction is carried out. It is easy to use during use. It produces construction waste, causes environmental pollution, is not environmentally friendly, and does not conform to the "green building" advocated by the national housing and construction department, four sections and one environmental protection building concept.
