Problems solved by technology

However, grouting reinforcement requires strict equipment and is expensive. It is mostly used for the protection of ancient buildings and is not suitable for popularization and use in native houses. Although the surface reinforcement of barbed wire can achieve a certain reinforcement effect, the construction process is complicated and the cost is high, so it is difficult to be economical. , Simple and easy-to-use technology for popularization and promotion

Embodiment 1

[0038] A single-story single-bay rammed-earth house 1# built in a laboratory is 2.6m long, 2.4m wide, and 2.2m high. The gable wall is 0.6m high and 0.6m thick. It is mainly reinforced by double-layer horizontal paste. The reinforcement diagram is as figure 1 , as shown in 2. The method is constructed in the following steps:

[0039] 1. Properly grind the inner and outer surfaces of the uneven raw soil wall 5 to make it basically smooth;

[0040] 2. Choose the pasting method, and cut the awning cloth for pasting to a width of 20cm. Spring the line on the inner and outer walls. The width of the elastic line is 20cm. This area is the pasting position. figure 1 As shown in 1 and 4, the pasting position of the gable wall can be oblique along the direction of the wall, such as figure 1 As shown in 2 in , the pasting position at the intersection of vertical and horizontal walls can be oblique, such as figure 1 Shown in 3.

Embodiment 2

[0048] A single-storey, single-bay rammed-earth house built in a laboratory is 2.6m long, 2.4m wide, and 2.2m high. The gable wall is 0.6m high and 0.6m thick. It is mainly reinforced by double-layer horizontal paste. The reinforcement diagram is as figure 1 , as shown in 2. The method is constructed in the following steps:

[0049] 1. Properly grind the inner and outer surfaces of the uneven raw soil wall to make it basically flat;

[0050]2. Choose the pasting method, and cut the carbon fiber cloth used for pasting into a width of 18cm. Spring the thread on the inner and outer walls, the width of the spring thread is 20cm, and this area is the pasting position. The sticking position of the inner and outer walls is kept at the same horizontal position, the sticking position of the gable wall can be oblique along the direction of the wall, and the sticking position of the junction of vertical and horizontal walls can be oblique.

Abstract

The invention discloses a reinforcing method of an earth construction wall, comprising the following steps 1), polishing an earth wall for smoothening; 2), selecting a bonding position on a wall surface; 3) applying sodium silicate to the selected bonding position on the wall surface; 4), preparing a bonding agent, filling wall surface cracks and pits with the bonding agent, applying the bonding agent to the wall surface that is painted with the sodium silicate, and leveling after application; 5), soaking cloth strips in sodium silicate, wringing the cloth strips that are full soaked, spreading the cloth strips, and bonding the cloth strips to the wall surface that is painted with the bonding agent in step 4), with the cloth strips lapped together; 6), when the bonding agent on the wall surface at the bonded cloth strip positions in step 5) hardens, applying the bonding agent to the surfaces of the cloth strips, leveling the surfaces, with sandwich layers formed between each cloth strip and upper and lower bonding layers; and 7), after the bonding agent on the surfaces of the cloth strips in step 6) harden, painting the wall. The method enables improvements in the integrity, lateral stiffness and wall extension of the earth wall and a significant improvement in the aseismic capacity of an earth construction.

Description

technical field [0001] The invention relates to the technical field of structural reinforcement. More specifically, it relates to a reinforcement method for raw earth building walls. Background technique [0002] Raw earth architecture refers to the building that mainly uses unroasted and only simply processed undisturbed soil as the main structure to build the main structure. It is the oldest and still widely used building type, almost all over the world. However, limited by the mechanical strength of materials, raw earth structure houses, whether adobe houses or rammed earth houses, inevitably have the problem of poor earthquake resistance. In addition, most of the raw earth structure houses currently used are distributed in rural areas and underdeveloped areas. The construction and daily maintenance conditions of the raw earth buildings are insufficient, which further weakens the earthquake resistance of the buildings. In earthquakes, they are often severely damaged, end...
