Abstract

The invention discloses a rammed earth wall construction method of a square steel pipe column and a steel bar. The rammed earth wall construction method comprises the steps that square steel pipes arepre-embedded in two sides of door and window holes and concrete foundations of corner columns of the rammed earth wall, and concrete is poured into the square steel pipes to form square steel pipe structural columns; horizontal steel bars are connected between the square steel pipe structural columns; wire grippers are tied in a butterflyshape on horizontal tied steel bars of the square steel pipe structural columns and in the square steel pipes at intervals, and the end tips of the wire grippers are dispersed and paved into the rammed earth wall between the two square steel pipes; and aftertamping of the rammed earth wall is completed, roof pressing is arranged, and the roof pressing is reliably tied with the main body structure. According to the rammed earth wall construction method, galvanized square steel pipes structural columns are arranged in the rammed earth wall, meanwhile the horizontal steel bars are arranged, and the overall bearing capacity and seismic performance of thewall can be improved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for constructing a rammed earth wall with square steel pipe columns and steel bars, which can enhance the bearing capacity and anti-seismic performance of the rammed earth wall. Background technique [0002] Rammed earth buildings have the advantages of local materials, simple construction, low cost, outstanding thermal performance, degradable regeneration, low energy consumption and no pollution during processing. In particular, rammed earth materials have an ecological cost-effective advantage that cannot be compared with conventional energy-saving materials in rural areas. However, it is undeniable that the inherent defects of traditional rammed earth in terms of craftsmanship, construction technology, seismic performance and durability make it difficult to meet the urgent needs of improving living quality and housing safety, and also restrict its mod...
