Problems solved by technology

[0003] In the above-mentioned technical scheme, the construction technology of using PC components and traditional wooden formwork to strengthen the cast-in-place is difficult to deal with at the junction of PC components and cast-in-place joints. At the same time, the use area of ​​the wooden formwork is reduced, and the unit price is greatly increased, resulting in an increase in cost
At the same time, the molding quality of wood formwork is quite different from that of PC components, and it is difficult to meet the requirements of the plaster-free process. In addition, the construction of wood formwork requires mechanical cooperation, which reduces the installation efficiency of PC components.

Abstract

The invention relates to a plastering-free construction method for a fabricated building. The method comprises the following steps that 1, PC components are prefabricated; 2, the PC components are rigidly connected by means of anchoring measures in a cast-in-situ section; 3, windowsill cast-in-place walls, T-shaped cast-in-place walls, L-shaped columnar cast-in-place walls and I-shaped cast-in-place walls are manufactured; 4, an operating platform is constructed, an installation area is constructed on the top of the operation platform, and then concrete is poured onto the installation area toform a floor. By adopting the steps above, the complex and lightweight components with a poor molding effect are prefabricated in a factory, the cast-in-place difficulty is reduced, and the work efficiency is improved; meanwhile, an aluminum alloy formwork is used in cooperation with the PC components or a PCF board formwork is used in cooperation with the PC components, so that the construction time is shortened; moreover, the aluminum alloy formwork is a new back-to-back formwork system with a sustainable use effect and is convenient to carry. After aluminum alloy is disassembled, the surfaces of the walls are flat, and a plastering-free effect is achieved.

Description

technical field [0001] The invention relates to the field of prefabricated houses, in particular to a plaster-free construction method for prefabricated houses. Background technique [0002] The prefabricated building model is a major trend in the development of the national construction industry. The prefabrication of complex components can greatly reduce the application area of ​​formwork and improve the effect of concrete molding. Under the condition of satisfying the prefabrication rate and assembly rate of the existing PC prefabricated buildings, the remaining parts are mostly constructed with wooden formwork, combined with the traditional wooden formwork reinforcement method, the PC components are hoisted, and finally the concrete is poured. [0003] In the above-mentioned technical solution, using PC components and traditional wooden formwork to strengthen the cast-in-place construction process, it is difficult to reinforce the joints between PC components and cast-in...
