Problems solved by technology

Its construction technology is basically traditional manual masonry and plastering, with high labor intensity, low efficiency, complicated procedures, and slow progress, and all wet operations, especially clay solid bricks, have been strictly restricted by policies
At present, the construction efficiency of fly ash hollow slats or gypsum slats is several times higher than that of blocks, and the floor space is small, but most slats have insurmountable weaknesses: heavy weight, inconvenient transportation, and high damage rate , Wall joints are easy to crack, etc.
In addition, there are prefabricated three-in-one exterior wall panels, which combine the enclosure structure layer (usually reinforced concrete), insulation layer (polystyrene board or rock wool board) and exterior surface into one, and are processed and formed in the factory at one time. , directly installed on site, but the production process is more complicated and the cost is too high
Using the traditional gypsum board and light steel frame as the partition wall has many disadvantages such as no sound insulation, no durability, poor impact resistance, and easy to be damp and cracked.

Abstract

The invention discloses a non-bearing wall body by gypsum pouring formed by a plurality of hollow gypsum keels and the gypsum encapsulating the keels. The gypsum is obtained by situ casting of a gypsum slurry, wherein each material weight part of the gypsum slurry is: 80-95 parts of a semi-hydrated gypsum powder, 3-15 parts of a batch, 0.5-2.5 parts of an air-leading water-reducing agent, and a water-solid ratio is 0.5-0.7. The semi-hydrated gypsum powder is a semi-hydrated natural gyspsum, a semi-hydrated phospho gypsum or a semi-hydrated desulfurized gypsum. The batch is one, two or more than two of a fly ash, a blast furnace slag and a cement. The air-leading water-reducing agent is one, two or more than two of a triterpenoid saponim, a calcium lignosulphonate, sodium beta-naphthalene sulfonic. The gypsum keels are formed by a hollow straight tube (1) and a thin straight tube (2) with holes (3) arranged on both ends of the hollow straight tube. The invention has high construction efficiency and high quality of the wall body and can greatly reduce labor intensity and enjoy low cost.

Description

technical field [0001] The invention relates to the field of building materials, in particular to non-load-bearing walls. Background technique [0002] At present, there are all kinds of non-load-bearing walls in the construction field, and 240mm solid clay bricks, clay hollow bricks, ceramsite hollow bricks, concrete hollow blocks, coke slag hollow blocks and aerated concrete blocks are mostly used. Its construction technology is basically traditional manual masonry and plastering, with high labor intensity, low efficiency, complicated procedures, and slow progress, and all wet operations, especially clay solid bricks, have been strictly restricted by policies. At present, the construction efficiency of fly ash hollow slats or gypsum slats is several times higher than that of blocks, and the floor space is small, but most slats have insurmountable weaknesses: heavy weight, inconvenient transportation, and high damage rate , Wall joints are easy to crack, etc. In addition,...
