Description

Technical Field

[0001] The present invention belongs to the field of gypsum wall construction methods, and particularly relates to a rapid forming method for a lightweight gypsum wall. Background Art

[0002] After the completion of the house frame, the construction of the cast-in-place gypsum wall is required. Usually, the moisture content of the wall is relatively high after construction. Affected by the actual construction environment, if in a relatively humid environment, the humidity difference between the inside of the wall and the environment is small, resulting in too slow drying speed of the wall. The long-term humidity of the wall will affect the further wall construction; while reducing the moisture in the slurry will cause the slurry to be too viscous to be constructed, thus restricting the construction progress. Therefore, there is an urgent need for a method that can rapidly form a lightweight gypsum wall to meet the construction requirements. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a rapid forming method for a lightweight gypsum wall. By means of an internal water absorption unit, the moisture in the wall can diffuse in two directions, inwards and outwards, accelerating the reduction of the wall moisture, enabling the rapid forming of the lightweight gypsum wall after construction, and meeting the progress requirements of subsequent construction.

[0004] The specific technical solution adopted by the present invention is: a rapid forming method for a lightweight gypsum wall, including the following steps,

[0005] a. Select the construction location of the lightweight gypsum wall;

[0006] b. Install a water absorption unit between the inner top surface and the bottom surface at the construction location;

[0007] c. Fill the construction location with gypsum slurry, and wrap the water absorption unit in the wall through the gypsum slurry to form a lightweight gypsum wall.

[0008] The water absorption unit is arranged in the wall by means of a fixing unit. The fixing unit includes a fixator and a fixing connector. The fixators are respectively fixed on the bottom surface and the inner top surface. The fixing connector is linearly connected between the fixators on the bottom surface and the inner top surface. The water absorption unit is block-shaped and fixed on the fixing connector.

[0009] The water absorption unit is arranged in the wall by means of a light steel framework. The light steel framework is arranged in a frame shape between the bottom surface and the inner top surface. The water absorption unit is stuffed in the gaps of the light steel framework; or the fixing connector is pulled by the frameworks on both sides of the gaps of the light steel framework. The water absorption unit is fixedly connected with the light steel framework by means of the fixing connector. The water absorption unit is block-shaped and fixed on the fixing connector.

[0010] The water absorption unit is vertically arranged in the wall in a columnar structure. A framework rod is arranged in the columnar structure of the water absorption unit, and the water absorption unit is arranged around the framework rod.

[0011] The water absorption unit is arranged between the inner top surface and the bottom surface by means of a support device.

[0012] The water absorption unit is made of hemihydrate gypsum and is formed by wrapping the outside with a permeable membrane or a water-soluble membrane.

[0013] A plurality of groups of the water absorption units are arranged at the construction position. By surrounding the wall formwork at the construction position, the water absorption units are surrounded to form a pouring space, and gypsum slurry is poured into the pouring space to bury the water absorption units therein, thereby completing the pouring of the lightweight gypsum wall.

[0014] A plurality of groups of the water absorption units are arranged at the construction position. At the construction position, a wire mesh is tied relying on the water absorption units, and a lightweight gypsum wall is formed by spraying gypsum slurry onto the wire mesh.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention adopts the form of adding water absorption units in the wall, enabling the moisture in the wall to diffuse in both the inner and outer directions, accelerating the reduction of the wall moisture, enabling the rapid formation of the lightweight gypsum wall after construction, and meeting the progress requirements of subsequent construction.

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0023] The present invention discloses a method for rapid formation of a lightweight gypsum wall, which includes the following steps:

[0024] a. Select the construction position of the lightweight gypsum wall;

[0025] b. Install the water absorption unit 3 between the inner top surface 1 and the bottom surface 2 at the construction position;

[0026] c. Fill the gypsum slurry at the construction position, and wrap the water absorption unit 3 with the gypsum slurry inside the wall to form a lightweight gypsum wall.

[0027] Specific embodiment 1 is as follows Figure 1 As shown, the water absorption unit 3 is arranged inside the wall by means of a fixing unit. The fixing unit includes a fixer 4 and a fixing connector 5. The fixer 4 is respectively fixed on the bottom surface 2 and the inner top surface 1. The fixing connector 5 is linearly connected between the fixers 4 on the bottom surface 2 and the inner top surface 1. The water absorption unit 3 is fixedly arranged on the fixing connector 5 in a block shape.

[0028] By embedding the water absorption unit 3 inside the wall, the original unidirectional volatilization of water from the inside to the outside is changed to the simultaneous internal self-absorption and volatilization from the inside to the outside, thereby accelerating the subsequent construction progress. Moreover, the water absorption unit 3 is pre-set in the wall cavity through the fixing unit, with rapid fixing, convenient construction and low operation difficulty, greatly improving the construction efficiency of the gypsum wall and ensuring high construction quality.

[0029] In this embodiment, the fixer 4 is at least one of a ceiling nail, an expansion nail, and an integral nail; the fixing connector 5 is a rope or a rigid rod. By first nailing the fixer 4 into the inner top surface 1 and the bottom surface 2, and then pulling the fixing connector 5 to form a vertical fixing unit, and then bundling or hanging the water absorption unit 3 in blocks onto the fixing unit, the construction speed is relatively fast, the bearing capacity of the fixing unit is large, and more water absorption units 3 can be hung. It is particularly suitable for use in a construction environment where the wall is thick and the moisture is more difficult to dry, which can greatly accelerate the construction progress and enable the rapid formation of the lightweight gypsum wall.

[0030] The fixing connector 5 is provided with rope loops or holes at intervals, and the water absorption unit 3 is connected to the fixing connector 5 by means of the rope loops or holes. Hooks or plugging rods are preset on the water absorption unit 3, so as to facilitate the fixation of the water absorption unit 3 and the fixing connector 5 and improve the construction efficiency.

[0031] Specific embodiment 2 is as follows Figure 2 As shown, the water absorption unit 3 is arranged inside the wall by means of a light steel framework 6. The light steel framework 6 is arranged in a frame shape between the bottom surface 2 and the inner top surface 1. The water absorption unit 3 is filled in the gaps of the light steel framework 6; or the fixing connector 5 is pulled by the frameworks on both sides of the gaps of the light steel framework 6, and the water absorption unit 3 is fixedly connected to the light steel framework 6 by means of the fixing connector 5. The water absorption unit 3 is fixedly arranged on the fixing connector 5 in a block shape.

[0032] Pre-assemble the light steel framework 6 at the construction position. After fixing the water absorption unit 3 to the light steel framework 6, by stuffing the block-shaped water absorption unit 3 into the frame gaps of the light steel framework 6, or using the light steel framework 6 as the riveting position to pull and fix the connecting member 5, where the fixed connecting member 5 is a rope or a rigid rod, and then hanging the smaller block-shaped water absorption unit 3 in the gaps of the light steel framework 6, so that the number of water absorption units 3 set can be flexibly adjusted according to the wall thickness, humidity of the construction environment, etc., to meet the needs of rapid construction.

[0033] Specific Embodiment 3, as Figure 3 shown, the water absorption unit 3 is vertically arranged in the wall in a columnar structure, and a framework rod 7 is arranged in the columnar structure of the water absorption unit 3, and the water absorption unit 3 is arranged around the framework rod 7. The water absorption unit 3 is arranged between the inner top surface 1 and the bottom surface 2 by means of a support device.

[0034] In this embodiment, as Figure 3 and Figure 4 shown, a water absorption column composed of wrapping the water absorption unit 3 outside the framework rod 7 is used as the water absorption unit 3 and arranged inside the wall. Compared with the block-shaped water absorption unit 3 fixed inside the wall by means of the fixed connecting member 5 in Embodiment 1, the structure of the water absorption column reduces the thickness of about half a block-shaped water absorption unit 3. Thus, while ensuring the water absorption effect, the thickness of the wall is reduced, increasing the actual usable area indoors. In addition, compared with the block-shaped water absorption unit 3, the water absorption column structure of the water absorption unit 3 is an integral structure, and the on-site assembly is faster. The support device is a commercially available external energy support device. By screwing the support device on-site to adjust the height of the support device, the water absorption column can be supported between the inner top surface 1 and the bottom surface 2 to complete the fixation, and the working efficiency is high.

[0035] As Figure 4 shown, a water-soluble film or a permeable film is wound around the surface layer of the water absorption unit, and a fixing rope is spirally wound outside the film layer, so that the water absorption unit and the film layer can be fixed to the framework rod 7 by means of the fixing rope, better binding the fixing film, thereby playing a role in fixing the water absorption layer of the water absorption unit to the framework rod.

[0036] Further, the water absorption unit 3 is made of semi-hydrated gypsum and is formed by being wrapped with a permeable film or a water-soluble film on the outside.

[0037] Semi-hydrated gypsum can effectively absorb the moisture in the wall, thereby achieving the purpose of drying the wall. At the same time, after semi-hydrated gypsum absorbs a certain amount of moisture, it will become dihydrate gypsum, which is similar to the wall material, making the water absorption layer form an integral body with the wall, thus making the structure of the entire wall more solid.

[0038] The water absorption unit 3 is a high water demand material or a high water absorption material wrapped by a water-soluble film or a water-permeable film, such as hemihydrate gypsum or dihydrate gypsum. After the water-soluble layer of the packaging is cracked or penetrated, the dry components in the water absorption unit 3 absorb some of the excess water in the cast-in-place wall, causing the excess free water in the cast-in-place wall system to be absorbed inward, and the dry components and water react to form a gelling material with a certain strength, ensuring the wall strength and solving the problem of slow drying of cast-in-place walls under high environmental humidity.

[0039] Further, multiple groups of the water absorption unit 3 are arranged at the construction position. By surrounding the wall formwork at the construction position, the water absorption unit 3 is surrounded to form a pouring space, and gypsum slurry is poured into the pouring space to bury the water absorption unit 3, completing the pouring of the lightweight gypsum wall.

[0040] Only taking Figure 1 and Figure 2 as an example, by setting a wall formwork on the water absorption unit 3, wrapping the water absorption unit 3 therein, and then pouring gypsum slurry into the pouring space surrounded by the wall formwork, the wall construction can be quickly completed.

[0041] Further, multiple groups of the water absorption unit 3 are arranged at the construction position. At the construction position, a wire mesh 8 is tied relying on the water absorption unit 3, and a lightweight gypsum wall is formed by spraying gypsum slurry onto the wire mesh 8.

[0042] Only taking Figure 3 as an example, by attaching a wire mesh 8 to the water absorption unit 3, the relatively thick gypsum slurry can adhere to the wire mesh 8, and a wall is formed by gradually spraying, eliminating the need to set up wall formwork, with simple construction steps and a fast rhythm.
