Problems solved by technology

[0003] Cracks: After the installation of this type of wallboard, cracks have become a common problem in the quality of this type of product, and have always been a major problem in the GRC light-weight panel industry, especially the cracks between the entire boards. Some projects can account for about 80% of all cracks. Seriously affect the use effect
[0004] Hanging force: In the process of use, due to the influence of the holes of this type of wall panel, when the user nails and hangs it during use, this type of wall panel cannot fully meet the requirements
[0005] Specifications and dimensions: traditional internal partition wall block masonry, or slat installation, the slat size is usually 600mm, the installation efficiency of these two methods is low, there are many links, and the quality is difficult to control

Embodiment 1

[0020] Clean the mold, apply mold release oil, lay the bound steel cage and embedded parts in the mold, then pour concrete and vibrate it, and then close the surface and remove the formwork for maintenance after the vibration is sufficient. The composition of the concrete is: 531kg of cement, 55kg of silica fume, 286kg of ceramsite, 140kg of ceramic granules, 12.9kg of vitrified microbeads, 1.8kg of tackifier, 13.1kg of polycarboxylate superplasticizer, and 150kg of water.

[0021] The properties of the wallboard prepared above are as follows: size 3000mm×3300mm×100mm, strength 9.1MPa, bulk density 1200kg / m 3 .

Embodiment 2

[0023] Clean the mold, apply mold release oil, lay the bound steel cage and embedded parts in the mold, then pour concrete and vibrate it, and then close the surface and remove the formwork for maintenance after the vibration is sufficient. The composition of the concrete is: 451kg of cement, 149kg of fly ash, 202kg of ceramsite, 297kg of ceramic granules, 0.8kg of tackifier, 9.2kg of polycarboxylate superplasticizer, and 204kg of water.

[0024] The properties of the wallboard prepared above are as follows: size 3000mm×3300mm×100mm, strength 14.3MPa, bulk density 1300kg / m 3 .

Embodiment 3

[0026] Clean the mold, apply mold release oil, lay the bound steel cage and embedded parts in the mold, then pour concrete and vibrate it, and then close the surface and remove the formwork for maintenance after the vibration is sufficient. The composition of the concrete is: 498kg of cement, 446kg of ceramsite, 145kg of ceramic granules, 9.2kg of polycarboxylate superplasticizer, 145kg of water, and 1.0kg of tackifier.

[0027] The performance of the wallboard prepared above is as follows: size 3000mm×3300mm×100mm, strength 12.3MPa, bulk density 1240kg / m 3 .

Abstract

The invention relates to a production process of a fabricated lightweight inner partition board. The production process comprises the following steps: cleaning a die; coating and brushing die releasing oil; paving a bound reinforced cage and an embedded part in the die; pouring concrete, and vibrating the concrete; and performing surface finishing and die releasing maintenance after the concrete is fully vibrated; wherein the concrete comprises cement, silicon powder, ceramsite, crushed ceramics, glazed hollow bead, tackifier, a polycarboxylate superplasticizer and water. According to the production process, a lightweight material or physical bubbles are introduced into the above lightweight concrete, so that the volume weight of the lightweight board can be reduced to be 1000 to 1400kg / m<3>, and the intensity of the lightweight board is more than 8MPa; meanwhile, the concrete is outstanding in working capacity and applicable to construction; and in addition, various physical performance indexes of the concrete meet the lightweight board standard requirements.

Description

technical field [0001] The invention relates to the field of construction, in particular to a production process for an assembled lightweight interior partition wall panel. Background technique [0002] The internal room partition wall of traditional buildings adopts on-site masonry. Traditional lightweight internal partition walls, including GRC lightweight internal partition walls and aerated concrete slabs, etc., although in terms of various performances, including key indicators such as sound insulation, surface density, and strength It meets the requirements of the standard JG / T 169-2005 (lightweight slats for building partition walls), but there are still the following defects: [0003] Cracks: After the installation of this type of wallboard, cracks have become a common problem in the quality of this type of product, and have always been a major problem in the GRC light-weight panel industry, especially the cracks between the entire boards. Some projects can account f...
