Prestressed rammed earth building wall and construction method thereof

Abstract

The invention relates to a prestressed rammed earth building wall and a construction method thereof, and belongs to the technical field of construction engineering. The prestressed rammed earth building wall comprises more than one set of pre-stressed assemblies, ground beams, rammed earth and ring beams, the ground beams are located at the bottom of a wall, the rammed earth is located at the upper parts of the ground beams, the ring beams are located at the upper parts of the rammed earth, and the more than one set of the prestressed assemblies are correspondingly arranged in the inner part of the ground beams, the rammed earth and he ring beams; and each of the pre-stressed assemblies includes an outer sleeve, a spring, a lower end plate, an upper end plate, an inner sleeve and a prestressed steel bar. According to the prestressed rammed earth building wall and the construction method thereof, the spring made of large diameter round steel is used as a part of a prestressed steel barto solve the problem of prestressed loss caused by excessive deformation due to too low elastic modulus of rammed earth materials, a lasting vertical prestressed stress is established in the wall of arammed earth building, even under the condition of the low elastic modulus, a large deformation generates, the prestressed loss cannot be much, and thus the seismic performance and the durability ofthe rammed earth wall are effectively guaranteed, and the effective technical quality assurance for the application of the rammed earth building is provided.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering, and relates to the construction of raw earth building walls, in particular to a prestressed rammed earth building wall and a construction method thereof. Background technique [0002] At present, more than one third of the world's population still live in houses built from raw soil. Rammed earth is a common application method for raw earth buildings, and it is widely used in ancient buildings. For example, the Qin Great Wall was built with rammed earth. The steel, cement, sintered bricks and tiles commonly used in modern buildings have severely damaged the ecological environment during the production process, and the degradation rate of cement products and sintered bricks and tiles in the natural environment is slow, which seriously pollutes the environment. However, both in the ancient times when the production method was backward or in the modern era, rammed earth buildings have ob...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is: to provide a prestressed rammed earth building wall and its construction method, to establish a lasting vertical precompression stress in the wall of the rammed earth building, in order to solve the problem that the elastic modulus of the rammed earth material is too high Low prestress loss caused by excessive deformation. The spring made of large-diameter round steel is used as a part of the prestressed steel bar, so that the wall of the rammed earth building will have a large deformation even under the condition of low elastic modulus. There will not be a lot of stress loss, so as to effectively ensure the seismic performance of the rammed earth wall
