Prefabricated constructional column used at exposed corner of wall and rammed earth wall structure as well as construction method thereof

Abstract

The invention provides a prefabricated constructional column used at an exposed corner of a wall and a rammed earth wall structure as well as a construction method of the rammed earth wall structure. The prefabricated constructional column is a prefabricated reinforced concrete structure consisting of an L-shaped columnar part and an end plate part, wherein a plurality of tie ring installing holes are formed in two constructional sides of the L-shaped columnar part; the L-shaped columnar part comprises external pouring concrete and a built-in reinforcement cage; the end plate is welded on the lower end of the built-in reinforcement cage; and a plurality of reserved connecting holes are formed in the end plate. The rammed earth wall structure comprises a base ring beam embedded in the ground and the wall arranged above the ground, wherein the wall comprises a rammed earth main body part and the prefabricated constructional column arranged at each exposed corner of the wall; and a plurality of tie bars are connected between the prefabricated constructional columns at the two ends of the same wall. The construction method of the rammed earth wall structure comprises the following steps of: step one. pouring the prefabricated constructional columns in advance; step two. pouring the base ring beam; step three. installing the prefabricated constructional columns on the base ring beam; and step four. ramming the wall. The prefabricated constructional columns have a protecting effect on the exposed corners of the wall. The rammed earth wall structure has relatively good integrality and durability.

Description

technical field [0001] The invention belongs to the field of building wall structures, and in particular relates to a prefabricated structural column used at an external corner of a wall, a rammed earth wall structure using the structural column, and a construction method for a rammed earth wall. Background technique [0002] As one of the main forms of traditional earth architecture, houses with rammed earth walls are widely used in the western region of my country. They have distinctive local and national characteristics, and are full of strong local history and cultural atmosphere. Houses with rammed earth walls are widely welcomed because of their advantages such as convenient materials, low cost, closeness to nature, energy saving, and thermal insulation. In order to improve the integrity and anti-seismic performance of the rammed earth wall, the method commonly used in China is to set wooden columns at the junction of the four corners of the house and the vertical and ...

AI Technical Summary

Problems solved by technology

In order to improve the integrity and anti-seismic performance of the rammed earth wall, the method commonly used in China is to set wooden columns at the junction of the four corners of the house and the vertical and horizontal walls, and to set horizontal wooden strips or plant fibers in the wall, but this will not improve the anti-seismic performance of the rammed earth wall. And the durability is not significant, at the same time, it will inevitably cause the felling of trees and the destruction of the ecological environment
