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 bonding. Reinforcement diagram as figure 1 , shown in 2. The method is constructed in the following steps:

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

[0040] 2. Select the pasting method, and cut the tarpaulin for pasting into a width of 20cm. Stretch the thread on the inner and outer walls, the width of the thread is 20cm, this area is the sticking position, and the sticking position of the inner and outer walls is kept at the same horizontal position, such as figure 1 As shown in 1 and 4, the gable wall can be pasted at an oblique direction along the direction of the wall, such as figure 1 As shown in 2, the pasting position at the junction of the vertical and horizontal walls can be oblique,...

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 bonding. Reinforcement diagram as figure 1 , shown in 2. The method is constructed in the following steps:

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

[0050]2. Select the pasting method, and cut the carbon fiber cloth used for pasting into a width of 18cm. Stretch lines on the inner and outer walls, the width of the stretch lines is 20cm, and this area is the sticking position. The pasting position of the inner and outer walls is kept at the same horizontal position, the gable wall can be pasted in an oblique direction along the direction of the wall, and the pasting position at the junction of the vertical and horizontal walls can be inclined.

[0058] 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 bonding. Reinforcement diagram as figure 1 , shown in 2. The method is constructed in the following steps:

[0059] 1. Properly polish the inner and outer surfaces of the uneven raw soil wall to make it basically flat;

[0060] 2. Select the pasting method, and cut the thick canvas for pasting into a width of 15cm. Stretch lines on the inner and outer walls, the width of the stretch lines is 20cm, and this area is the sticking position. The pasting position of the inner and outer walls is kept at the same horizontal position, the gable wall can be pasted in an oblique direction along the direction of the wall, and the pasting position at the junction of the vertical and horizontal walls can be inclined.

Abstract

The invention discloses a method for reinforcing a raw soil building wall, which comprises the following steps: 1) grinding the raw soil wall to make it smooth; 2) selecting a sticking position on the wall; 3) selecting a sticking position on the wall Brush the water glass on the top; 4) configure the adhesive, fill the cracks and pits on the wall with the adhesive, and apply the adhesive to the surface of the wall that has been brushed with water glass, and level it after the application; 5) put the cloth strip Soak in water glass, wring out and flatten after soaking, then stick the cloth strips on the wall surface coated with adhesive in step 4), and the cloth strips should overlap each other; 6) Wait for the paste in step 5) When the adhesive on the surface of the wall at the cloth strip is hardened, apply the adhesive on the surface of the cloth strip, then scrape the surface flat, and the cloth strip and the upper and lower layers of adhesive form a sandwich layer; 7) wait for step 6) to cloth After the adhesive on the surface of the strip has hardened, paint the wall. The method can improve the integrity, lateral rigidity and wall ductility of the raw earth wall, and can obviously improve the earthquake resistance of the raw earth building.

Description

technical field [0001] The invention relates to the technical field of structural reinforcement. More specifically, it relates to a method for strengthening a wall of a raw earth building. Background technique [0002] Soil architecture refers to buildings that mainly use unbaked undisturbed soil for simple processing as the material to build the main structure. It is the oldest and still widely used building type, almost all over the world. However, due to the limitation of the mechanical strength of materials, the raw soil structure house, whether it is an adobe house or a rammed earth house, inevitably has the problem of poor seismic resistance. In addition, most of the currently used raw soil structure houses are distributed in rural areas and underdeveloped areas. The construction and daily maintenance conditions of raw soil buildings are insufficient, which further weakens the earthquake resistance of the building, and is often severely damaged in earthquakes, endange...
