Embodiment 1

[0030] The cast-in-place hollow lightweight inner partition wall of this example is an L-shaped partition wall. In the wall body 1 made by the cast-in-place method, a hollow cylinder body 2 is inlaid, and the hollow cylinder body 2 is a hollow paper tube. Such as Figure three As shown, before the wall body is dry, the lower part of the hollow cylinder body 2 is provided with a ventilating and dehumidifying hole 3 , and the ventilating and dehumidifying hole 3 passes through the wall body 1 . The wall body 1 is a cement-based wall body. Such as Figure ten As shown in 2, the cast-in-place method is to fix a row of templates 8 on one side of the partition wall to be poured, then fix the hollow cylinder 2 in the middle of the partition wall to be poured, and the both sides of the hollow cylinder 2 are provided with Wall thickness control parts 4 (such as Figure four shown), and then fix a row of templates 8 on the other side of the partition wall to be poured, and the termi...

Embodiment 2

[0033] The cast-in-place hollow lightweight inner partition wall in this example, such as Figure 1 and Figure II As shown, it is a straight partition wall. Except that the wall body 1 is a gypsum-based wall body, the terminal of the formwork is connected to the existing wall body, and the self-leveling inorganic gelling slurry is a self-leveling gypsum-based slurry, the rest is the same as the first embodiment.

[0034] Among them, the self-leveling gypsum-based slurry is: 100% gypsum, mixed with appropriate amount of water.

Embodiment 3

[0036] The cast-in-place hollow lightweight inner partition wall in this example, such as Figure 1 and Figure II As shown, it is a straight partition wall. Except for the self-leveling gypsum-based slurry, the others are the same as in the second embodiment.

[0037] Among them, the self-leveling gypsum-based slurry is: gypsum 50-85%, limestone 5-35%, medium sand 5-40%, perlite 1-5%, starch ether 0.1-0.2%, defoamer 0.01-0.03 %, add appropriate amount of water and stir.

Abstract

The invention relates to a cast-in-place hollow lightweight inner partition wall in the building construction field and is characterized in that a hollow cylinder (2) is embedded in a wall body (1) which is manufactured by adopting a cast-in-place method. The cast-in-place method comprises the steps of: fixing a row of mold boards at one side of the partition wall needing to be casted, later fixing the hollow cylinder in the middle of the partition wall needing to be casted, and then fixing another row of mold boards at the other side of the partition wall needing to be casted, wherein the terminals of the two rows of mold boards are connected with the existing wall body or an L-type component or a T-type component; casting inorganic cementitious slurry with self-leveling property between the two rows of mold boards, forming the cast-in-place hollow lightweight inner partition wall by curing at normal temperature, and then dismantling the mold boards at the two sides of the partition wall. The cast-in-place hollow lightweight inner partition wall is embedded with a hollow cylinder in the wall body, has the advantages of compact structure, no paving seams, better strength and sound insulation effect, light wall body, simple construction and lower cost, does not need prefabricated wall panel and also does not need the extraction of the hollow cylinder.

Description

Technical field: [0001] The invention belongs to the field of building construction, and in particular relates to a cast-in-place hollow lightweight inner partition wall. Background technique: [0002] In the existing technology, the inner partition wall is mostly made of masonry, and the wall surface of the masonry is uneven, and it is necessary to apply a layer of mortar on the wall surface for leveling, and the operation is complicated; moreover, the surface density of the wall body is relatively high. Large, which increases the load of the building, directly increases the construction cost, and the masonry is easy to cause cracks on the wall, which affects the use effect. For example, the existing gypsum blocks and gypsum slats have the disadvantages of complex manufacturing process, difficult construction, large storage space during production, high transportation costs, large-scale production investment, and poor structural stability after molding. China's No. 2006100...
