Environment-friendly and energy-saving integrated cast-in-situ lightweight concrete wall and construction method thereof

Abstract

The invention discloses an environment-friendly and energy-saving integrated cast-in-situ lightweight concrete wall and a construction method thereof. The wall comprises a wall body made from formwork cast-in-situ lightweight concrete, and tie bars. The tie bars are arranged on structure columns at the two ends of the wall body and located on a structure beam on the top of the wall body and anchored in the wall body. Wire boxes and pipelines are embedded into the wall body. Holes and door and window holes are reserved in the wall body. The cast-in-situ process is adopted, construction is convenient and rapid, the flatness of the wall obtained after formwork removal is high, plastering is not needed, rendering is avoided, and building rubbish is reduced. The wall is high in strength and capable of being suspended, bolts can be directly embedded, the problems that formwork collapse is caused by too high lateral pressure during vertical pouring of foam concrete, and layering non-uniformity is generated due to sedimentation are solved, one-time pouring can be achieved for the wall with the vertical height of 3-4 m, the whole construction process is shorted by almost half compared with the brick laying construction period, construction efficiency is improved, engineering management cost is reduced, the rate of return on investment is increased, and good economic benefits and social benefits are achieved for enterprises.

Description

technical field [0001] The invention relates to a lightweight energy-saving wall, in particular to a green and energy-saving integrated cast-in-place lightweight concrete wall, and also relates to a construction method for the wall. Background technique [0002] Since the beginning of the new century, governments at all levels in our country have listed the innovation of wall materials as one of the important contents of building energy conservation. For the wall of a building, in addition to certain mechanical properties, it is also required to have excellent thermal insulation, heat insulation, sound insulation, waterproof, fire prevention and other properties. When constructing the wall, if the masonry method is used, the labor cost is high and the construction efficiency is low. With the increase in labor costs and the advancement of mechanized construction, on-site masonry is no longer suitable for the needs of current building development; if prefabricated wall panels ...

AI Technical Summary

Problems solved by technology

Pour lightweight concrete into the wall cavity formed by the keel and the fiber cement pressure plate. The fiber cement pressure plate is used as a formwork. The bonding force between the lightweight concrete and the formwork is not strong, resulting in the separation between the concrete and the formwork to form a gap. , seriously affect the strength of the wall and the hanging force, etc.

These defects restrict the further development of cast-in-place lightweight concrete walls
