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

Embodiment Construction
[0031] A prestressed rammed earth building wall, such as Figure 8 As shown, it includes more than one set of prestressed components, ground beam 4, rammed earth 7 and ring beam 8;
[0032] Each set of prestressed components, such as Figure 4 As shown, all include outer sleeve 2, spring 3, lower end plate 301, upper end plate 302, inner sleeve 5 and prestressed steel bar 6;
[0033] The outer casing 2, such as Figure 3 ~ Figure 8 As shown, it is made of steel pipe, the inner diameter of which is 0.5 mm to 5 mm larger than the outer diameter of the inner casing 5, and the bottom is connected to the lower end plate 301;
[0034] The inner casing 5, such as figure 1As shown, steel pipes are used to prepare and go deep into the inside of the outer sleeve by 50 mm to 500 mm. The outer diameter is 0.5 mm to 5 mm smaller than the inner diameter of the outer sleeve 2, and the inner diameter is 0.5 mm to 5 mm larger than the outer diameter of the upper end plate 302, and the top i...

A prestressed rammed earth building wall and a construction method thereof, belonging to the technical field of construction engineering, comprising more than one set of prestressed components, ground beams, rammed earth and ring beams, the ground beams are located at the bottom of the wall, and the rammed earth Located on the upper part of the ground beam, the ring beam is located on the upper part of the rammed earth, and more than one set of prestressed components are arranged inside the ground beam, rammed earth and ring beam; the prestressed component includes an outer casing, a spring, a lower end plate, and an upper end plate , inner casing and prestressed steel bars. The invention adopts the spring made of large-diameter round steel as a part of the prestressed steel bar, which solves the problem of prestress loss caused by excessive deformation caused by too low elastic modulus of the rammed earth material, and establishes a durable structure in the wall of the rammed earth building. Vertical precompression stress, even if a large deformation occurs under the condition of low elastic modulus, the loss of prestress will not be much, so as to effectively ensure the seismic performance and durability of the rammed earth wall, and provide a good foundation for the application of rammed earth buildings. effective technical quality assurance.
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 1 / 3 of the world's population still lives in houses built with raw soil. As a common application method of raw earth construction, rammed earth was widely used in ancient buildings. For example, the Qin Great Wall was built with rammed earth in large quantities. The steel, cement, and fired bricks and tiles commonly used in modern buildings seriously damage the ecological environment during the production process, and cement products and fired bricks and tiles degrade slowly in the natural environment, seriously polluting the environment. However, both in ancient times when production methods were backward and in today’s era, rammed earth buildings have obvious ecological advan...
