A construction method for high-strength thin rammed earth walls of 40mm~100mm

Abstract

The invention relates to the field of building rammed earth walls, in particular to a construction method for high-strength thin rammed earth walls of 40 mm to 100 mm in size, in which steel-wood formwork and steel keels are produced as required; the base layer of the wall surface is treated; and evenly painted and isolated on the formwork to be used First, firmly support a layer of formwork next to the wall to be rammed. The distance from the formwork to the wall is the thickness of the ultra-thin rammed earth wall; stir to make the rammed earth wall mixture; feed and ram, the thickness of the bulk material is 150mm each time, Use a pneumatic tamping machine to tamp quickly from the formwork to the wall, and then tamp at a slow speed to ensure that the falling points of the rammer are connected; each time the tamping is completed, continue to add material and tamp, and so on until the ultra-thin The rammed earth wall is completed; after 36 hours of solidification of the wall, the formwork can be removed, and then the wall is coated with a protective agent. After drying, it can be evenly painted again. High and durable, through the alternate treatment of different rammed materials, it can also naturally present strip-like gradient textures, with remarkable artistic effects.

Description

technical field [0001] The invention relates to the field of building rammed earth walls, in particular to a construction method for high-strength thin rammed earth walls with a thickness of 40 mm to 100 mm. Background technique [0002] The construction of rammed earth walls has a long history and has become a beautiful landscape in modern buildings. Using rammed earth walls as the interior and exterior wall decoration of buildings is not only beautiful and tasteful, but also has the effect of wall insulation, which is welcomed by the public and recognized by the market. [0003] As a decoration for various types of walls such as concrete walls, brick-concrete walls or brick walls, whether they are load-bearing walls, enclosure walls, or landscape walls, if the rammed earth wall for decoration is too thick, it is neither economical nor suitable. However, with the existing technology and materials, the rammed earth wall made is either more than 400mm or about 200mm. Even if ...

AI Technical Summary

Problems solved by technology

[0005] 1. The lack of material ratio leads to the substandard performance of the rammed earth wall, which is prone to quality problems in the later stage and shortens the service life of the wall

[0006] 2. The existing rammed earth wall is usually more than 100mm, which is too thick and requires a lot of soil resources and energy, resulting in waste, and the ramming construction period is long, and the labor and material costs are high

[0007] 3. The unreasonable technological process such as the base treatment of the wall surface has buried hidden dangers for the quality of the rammed earth wall in the later stage. The combination between the foundation wall and the rammed earth wall is not tight, and it is easy to bulge, crack or even separate from each other for a long time
