Plastering-free building wall construction technology

Abstract

The invention discloses a plastering-free building wall construction technology, which belongs to the technical field of building construction. The plastering-free building wall construction technology includes the following steps: (1) base course cleaning: the residual mortar and sundries in the masonry part are cleared, and the parts protruding from the masonry surface and the exposed steel barheads and lead wire ends are cleared; (2) positioning and setting-out: measurement setting-out should be matched with the measurement net of the main structure, and the plane and elevation baselines of the external wall are turned out based on the baseline of the main structure; (3) constructional column form erecting, steel bar planting and binding: a pair of constructional column prefabricated templates is used as templates; and (4) polymer mortar mixing and group laying: building blocks are laid on an infilled masonry wall, and the joints of the infilled masonry wall and the constructionalcolumns are built into serrated racking structures. The prefabrication of combined fabricated buildings can be realized. Form erecting is carried out by using prefabricated concrete slabs instead of the traditional wooden formwork, and the building wall is not easy to crack and hollow. Compared with the traditional plastering technology, the quality of the wall has significant advantages.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically relates to a plaster-free construction process for building walls. Background technique [0002] With the construction of an environment-friendly and resource-saving society in my country and the introduction of energy-saving and emission-reduction policies, the reform of wall materials is also deepening. As one of the main forces of new wall materials, aerated concrete blocks are being used More and more people accept that China's cities have developed faster and faster in recent years, and construction technology is also at the forefront of the world, especially the development of plaster-free construction technology is extremely rapid, and it is replacing traditional wall plastering technology. Leading the trend of free-plastering buildings worldwide. [0003] The Chinese Invention Publication No. CN106049780A discloses a high-precision masonry-free plasterin...

Problems solved by technology

[0004] At present, most of the plaster-free technology in my country starts from the masonry itself or the putty layer on the surface to improve or create technology. However, due to the influence of the operating space environment, the construction column is prone to large deviations in verticality and flatness of the wall, and the structural Before concrete pouring, the column needs a series of cumbersome processes such as planting bars, supporting formwork, binding steel bars, and demolishing the formwork. It is also prone to problems such as mold expansion, formwork running, insufficient protection of the finished wall, grout leakage, honeycomb, and pockmarked surfaces. To achieve the effect of quasi-clear water without plastering will increase the thickness of the subsequent wall plastering layer, which not only wastes raw materials, but also the plastering process is very cumbersome and complicated, which seriously restricts the development of plastering-free process
