Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a cast-in-place assembled formwork-free thermal insulation integrated house. Background Art

[0002] With the acceleration of the process of urbanization in rural areas of my country, the construction of urbanization should also be adapted to its rapid development. However, the materials and methods of traditional urban housing cannot meet the needs of this development. For example, the load-bearing walls and load-bearing partitions of traditional housing are made of bricks, which are manually stacked. There are shortcomings such as destroying land resources, wasting energy, polluting the environment, high production costs, and time-consuming and labor-intensive brick making; and the stacking process is time-consuming and labor-intensive, the construction period is long, and the quality is difficult to guarantee; the stacked walls have poor earthquake resistance, consume a lot of materials, have low strength, poor cold and heat insulation performance, high construction costs and poor quality.

[0003] In traditional exterior wall construction, after the steel bars are tied, workers install the outer and inner formwork and support system on the scaffolding platform and floor slab respectively. The inner and outer formwork form a concrete pouring cavity under the joint action of the inner support and tension bolts or tension flat irons. After the concrete reaches the demolding strength, the formwork and support are removed. As is known to all, the traditional construction method has the defects of low construction efficiency and high labor intensity. With the rapid development of building templates, non-disassembly templates have appeared in recent years. This template will be integrally formed with the concrete after pouring, and does not need to be removed after forming. As part of the wall, if it is used as an exterior wall, its inner side is generally provided with an insulation board, and the outer side can also be provided with a decorative layer, so that the decorative layer and the insulation board can be formed at one time, which greatly reduces the construction efficiency and improves the firmness of the insulation board. In the prior art, the insulation board is generally bonded twice or simply composited; in practice, there are problems such as low construction efficiency, high labor intensity, and easy detachment of the insulation board; for the inner wall, the insulation board is often not required, and the non-disassembly template can be directly spliced ​​to form the pouring wall after the pouring is completed, forming the inner partition wall; according to market research and experiments, there is a problem with the existing non-disassembly template, which has insufficient strength, loose bonding of the insulation board, leakage of slurry and water in the actual splicing process. For this reason, the present invention provides a method with high construction efficiency, which can reduce construction costs, save energy consumption, and shorten the construction period.
