Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the rammed earth wall has weak anti-seismic ability, the wall is easy to crack, the rammed earth wall uses a lot of soil materials, and the reinforced concrete structural column and ring beam are difficult to coordinate with the rammed earth wall to bear the force. A construction method for rammed earth walls suitable for high-intensity areas of seismic fortification, which overcomes the above-mentioned shortcomings of the existing rammed earth wall technology

Embodiment 1

[0076] Embodiment 1: According to the adobe wall layout of the architectural design, firstly, on the reinforced concrete strip foundation 9, a vertical threaded steel bar 5 is pre-embedded respectively at the center of the intersection of the vertical and horizontal walls and at the center of both sides of the reserved door and window holes; On the reinforced concrete strip foundation 9, according to the wall size of the rammed earth wall, a rammed earth wall formwork 6 is supported; in the inner wall of the outer wall of the rammed earth wall formwork 6, pre-embedded mandrels I2 and pre-embedded mandrels II3 are alternately embedded in sequence . If it meets the intersection of the vertical and horizontal walls of the two outer walls, place the core column hole forming device 1 at the central position, and apply a viscous waterproof layer 10 on the surface of the core column hole forming device 1; if it meets the intersection of the vertical and horizontal walls of the externa...

Abstract

The invention relates to a construction method for an anti-seismic rammed earth wall with a reinforced surface skin and core columns and belongs to the technical field of construction engineering. According to the method, a rammed earth wall formwork is manufactured, and pre-embedded core molds are placed into the rammed earth wall formwork. The effect of the surface skin is reinforced under the tying and connecting action of two kinds dovetail joint type earth materials in the mode that different earth materials are added twice; the anti-seismic performance of the rammed earth wall is enhanced under the action of criss-cross tying and connecting action by prefabricating the pore-forming core columns, earth mass reinforcing columns and steel wire sewn mesh sheets. The method has the advantages that the construction cost of the rammed earth wall is lowered, and the durability and reliability of the rammed earth wall are improved.

Description

technical field [0001] The invention relates to a construction method of an anti-seismic rammed earth wall with a reinforced skin and a core column, belonging to the technical field of construction engineering. Background technique [0002] Rural traditional rammed earth houses are an important part of traditional villages maintaining their style and features. They have the characteristics of local materials, low cost, simple construction, and environmental friendliness. They are widely used in some specific poverty-stricken rural areas in my country. However, traditional raw earth materials have low strength, large deformation, and poor water resistance, which lead to obvious defects in rural traditional rammed earth houses in terms of earthquake resistance and durability. Judging from the current situation, traditional rammed earth houses in rural areas are gradually withdrawing from the stage of rural house construction. However, today when people are generally concerned...
