Fabricated cement fiberboard composite wallboard, manufacturing process and outer wall

Abstract

The invention provides a fabricated cement fiberboard composite wallboard. The composite wallboard is composed of cement fiberboards and foam concrete, the cement fiberboards serve as shells of the composite wallboard to be attached to the front face and the back face of the foam concrete, and a light steel keel stress structure is additionally arranged in the foam concrete; the foam concrete is prepared from the following components in parts by weight: 80-90 parts of quick-hardening Portland cement, 4-5 parts of lime, 0.4-0.5 part of ceramsite, 3-7 parts of a slurry stabilizer, 48-55 parts ofwater and 0.1-0.5 part of foam; and the left side and the upper side of the composite wallboard are provided with convex rabbets, and the right side and the lower side of the composite wallboard areprovided with concave rabbets. The super-long service life is ensured, the adaptability to various climates is better, and the fabricated cement fiberboard composite wallboard can be widely applied tobuilding places with high requirements on heat insulation performance.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to an assembled cement fiberboard composite wallboard, a manufacturing process and an outer wall thereof. Background technique [0002] With the development of society and the improvement of industrialization, the development trend of prefabricated buildings is obvious. There are more and more steel structure prefabricated buildings, and the demand for enclosure materials is increasing. At present, there are various materials for the enclosure system. Wallboard materials include metal sandwich panels and cement substrates (such as autoclaved aerated concrete panels. , cement fiberboard) and other lightweight wallboards, most of the insulation materials are polyurethane, rock wool and other materials, all of which are assembled and composited on site, and the joints are waterproof by weather-resistant glue. Due to the limitations of the material properties and thickness of the e...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from many engineering application examples that the current wall implementation has the following disadvantages: 1) On-site assembly of steel purlins requires a lot of work, and the purlins are basically welded and connected on site. The amount of welding is large, and the quality of on-site welding anti-corrosion is difficult to guarantee; 2) The on-site assembly of thermal insulation materials, such as polyurethane and rock wool, is greatly affected by the climate, and the materials after being exposed to moisture or water have a great impact on the quality of the project, and the large dust of the materials poses a threat to the health of workers; 3) There are many installation procedures for on-site composite walls, The construction flow time is long and the installation quality is not easy to control, which does not meet the requirements of the prefabricated building construction concept of "fast construction speed, good quality, and low cost"

The main disadvantages of ALC panels are obvious. Autoclaved aerated concrete panels are not suitable for walls in high-humidity environments. Due to product batch problems and surface pollution during on-site installation, the wall surface needs to be puttyed after being put in place. The workload of secondary exterior decoration such as spraying paint does not meet the requirements of modular construction
