Description

Prefabricated partition wall

Technical Field

The utility model belongs to the building industrialization field, concretely relates to prefabricated partition wall.

Background

Prefabricated partition wall on the market at present mainly divide into: prefabricated reinforced concrete partition wall, autoclaved aerated concrete batten, ceramsite concrete batten, and foaming concrete inorganic composite partition wall.

The rigidity of the prefabricated reinforced concrete partition wall is too large, and the influence on the rigidity of the structure is deeper relative to other partition walls, so that the original structure stress system of the main structure body is damaged. And the dead weight is also larger, and the installation is difficult.

The autoclaved aerated concrete slabs can be molded only by high-temperature high-pressure steam curing, the steam pressure and the temperature of a boiler room of a common prefabricated part factory cannot meet the requirements, and if a boiler room needs to be additionally arranged for production, the cost is increased. And because the required steam temperature is too high, the PVC pipe can be melted, so that the pipeline cannot be pre-buried.

The ceramsite particles of the ceramsite concrete strip plate have low density, and the particles float upwards, so that the concrete is easy to delaminate, isolate, reduce homogeneity and have uneven surface; the decrease of homogeneity will bring adverse effect to the strength, durability and other properties of the ceramsite concrete, and is difficult to control in the engineering.

The foamed concrete inorganic composite partition wall has the advantages that the strength of the foamed concrete is low, demolding can be carried out only when the strength of the foamed concrete completely meets the requirement, the production process is long, and the foamed concrete inorganic composite partition wall is easy to damage during hoisting and installation.

The problem of prefabricated partition wall on combining present market needs to develop a wall body dead weight light, need not to increase equipment, can produce the novel partition wall system of installation fast, satisfies the demand in market.

SUMMERY OF THE UTILITY MODEL

In order to overcome the current prefabricated partition wall dead weight too big, need to establish equipment in addition, install the easy damaged not enough, the utility model aims at providing a prefabricated partition wall, this prefabricated partition wall dead weight is little, is difficult for causing the damage in the hoist and mount installation.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:

a prefabricated partition wall is characterized by comprising an inner filling layer, an outer frame layer surrounding the inner filling layer and a blocking layer for separating the outer frame layer from the inner filling layer, wherein the prefabricated partition wall comprises the inner filling layer, the outer frame layer and the blocking layer; frameworks are pre-embedded in the inner filling layer and the outer frame layer; the outer frame layer is prefabricated by first concrete, the inner filling layer is prefabricated by second concrete, and the strength of the first concrete is higher than that of the second concrete;

the inner filling layer mainly plays a role in reducing the dead weight of the wallboard, and the outer frame layer mainly plays a role in strengthening. Generally, a first concrete is poured to form an outer frame layer, and then a second concrete is poured to form an inner filling layer. When filling layer intensity has not reached the requirement completely including, the intensity on frame layer has been very high, makes the wallboard reach the drawing of patterns requirement in advance through the enhancement on frame layer, and the wallboard is not fragile in the installation. Because the intensity of the inner filling layer is lower, the framework mainly plays a reinforcing role. The barrier layer mainly plays the isolation effect, prevents that the outer frame layer concrete of pouring earlier from flowing into the inboard and waiting to pour the interior filling layer of pouring and pouring in the region.

The framework comprises truss ribs and a reinforcing mesh, the truss is fixedly connected with the reinforcing mesh to form a reinforcing cage, and the reinforcing mesh penetrates through the blocking layer and stretches into the outer frame layer.

The first concrete strength grade is not lower than C30, and fine aggregate early strength concrete is preferred.

The second concrete is foamed concrete.

The barrier layer is a dense mesh steel wire mesh. The bonding power of the dense mesh steel wire mesh and concrete is good, the dense mesh steel wire mesh can be directly buried in the wallboard, the dense mesh steel wire mesh does not need to be taken out after pouring, and the production is convenient.

The thickness of frame layer is less than wallboard thickness, the closely attached in wallboard lower surface in barrier layer bottom, the partly outside extension of intussuseption layer forms the extension section to frame layer's top and/or below, and the thickness sum of this extension section, frame layer and barrier layer equals the thickness of prefabricated wall board.

And hanging nails are further arranged at the outer boundary of the outer frame layer.

Compared with the prior art, the beneficial effects of the utility model are that:

1. because the partition wall is formed by combining the foamed concrete and the frame concrete, the self weight of the wall body is reduced, the peripheral strength of the wall body is strong, and the wall body is not easy to damage in the hoisting and mounting processes;

2. due to the blocking effect of the blocking layer, the foamed concrete can be rapidly poured after the frame concrete is poured, the adhesive force between the dense mesh steel wire mesh and the concrete is good, the dense mesh steel wire mesh does not need to be taken out, the working procedure is simple, and the time is saved.

3. The steel reinforcement cage is mainly bound by the steel reinforcement net piece and the truss rib, the steel reinforcement net piece and the truss rib are both produced mechanically, and the steel reinforcement cage is simple to manufacture and saves time.

4. The foamed concrete is produced by the foamed slurry, has high fluidity and high pouring speed, and can greatly improve the efficiency, thereby being convenient for factory production.

5. The self strength of the foaming concrete is low, and later stage water and electricity transformation is met, so that the transformation process is easier than that of a concrete wallboard.
