Prestressed loam wall and construction process thereof

Abstract

The invention relates to a prestressed loam wall and a construction process thereof. The prestressed loam wall comprises a wall body, wherein the wall body is a loam wall body, sleeves are arranged in the wall body, the sleeves are arranged along the length direction of the wall body and penetrate through the whole wall body, prestressed steel bars are arranged in the sleeves, fixed plates are respectively arranged on both sides of the wall body, threads are formed on both ends of the prestressed steel bars, and the both ends of the prestressed steel bars respectively pass through the two fixed plates and are fixed with the fixed plates through washers and locking nuts. According to the prestressed loam wall and the construction process, a plurality of groups of prestressed steel bars are arranged along the height direction of the loam wall, the prestressed steel bars are arranged along the length direction of the loam wall, and additionally, the prestressed steel bars are fixed with two side surfaces of the loam wall through steel plates, so as to apply inward extrusion force to the loam wall, so that the loam wall is in a multidirectional pressed state, the compression resistance and the shear resistance of the loam wall are effectively increased, vertical straight joints can be effectively prevented from being formed, the height-thickness ratio of the wall body is effectively reduced, and the building height of the wall body is increased on the premise that the thickness of the wall body is not increased.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of traditional dwelling construction reinforcement, and in particular relates to a prestressed rammed earth wall and a construction process thereof. [0003] Background technique: [0004] The rammed-earth technology originated earlier in my country. Platforms, city walls and walls built with rammed-earth technology have appeared in the Longshan Culture about 4,000 years ago. Houses made of rammed earth walls are widely distributed in my country, with distinctive local and national characteristics, full of strong local history and cultural atmosphere, and are an important part of traditional dwellings in my country; representative ones are: Xinjiang Jiaohe Ancient City in Turpan, Tulou in southern Fujian, plate-walled houses in the Central Plains, Tuzhangfang in Yunnan, rafters and walls in Shaanxi, watchtowers in Sichuan, etc. Houses with rammed earth walls are very popular because of their advant...

AI Technical Summary

Problems solved by technology

Installing rigid pads under the purlins of rammed earth walls can well solve the local compression problem of rammed earth walls; setting foundation ring beams can effectively prevent uneven settlement of the foundation, and can solve the problem of vertical through cracks to a certain extent , but the difference in elastic modulus between the ring beam material and the wall soil is likely to cause the problem of soil cracking when the temperature changes; adding "grass tendons" to the rammed earth wall soil can improve the tensile properties of the soil to a certain extent. However, the "grass tendon" buried in the soil has limited force and poor durability

In addition, in order to increase the height of the rammed earth wall, the method of widening the thickness is usually used, but the effect is not very good because the soil is heavy and the strength is low
