Problems solved by technology

Raw earth structures are still vigorous after thousands of years of wind and rain, especially in the rural areas of western my country. It is still difficult to demolish and rebuild such a large number of houses with raw earth structures in a short period of time. To improve the problem of poor seismic performance of raw earth structures, a This is an imminent and significant measure for the reinforcement and reconstruction of existing raw earth structure houses

Embodiment 1

[0029] Take the wall size 4950mm (length) × 3900mm (height) × 720mm (thickness) as an example, such as figure 1 and figure 2 As shown, the rammed earth wall reinforcement method of the present embodiment comprises the following steps:

[0030] Step 1, building brick columns 2 for wrapping both ends of the rammed earth wall 1 at both ends of the rammed earth wall 1, and filling the gap between the rammed earth wall 1 and the brick columns 2 with cement mortar during the masonry process;

[0031] Step 2. When the brick column 2 is built to 1 / 4 of the height of the rammed earth wall 1, holes are drilled at both ends of the rammed earth wall 1, and then the holes at both ends of the rammed earth wall 1 are inserted and the surface is coated with cement mortar continue to build the brick column 2 and press the anchor bar 4 outside the rammed earth wall 1 into the brick column 2, and use cement mortar to fill the gap between the rammed earth wall 1 and the brick column 2 during th...

Embodiment 2

[0038] Take the wall size of 5500mm (length) × 3600mm (height) × 720mm (thickness) as an example, such as figure 1 and figure 2 As shown, the rammed earth wall reinforcement method of the present embodiment comprises the following steps:

[0039] Step 1, building brick columns 2 for wrapping both ends of the rammed earth wall 1 at both ends of the rammed earth wall 1, and filling the gap between the rammed earth wall 1 and the brick columns 2 with cement mortar during the masonry process;

[0040] Step 2. When the brick column 2 is built to 1 / 5 of the height of the rammed earth wall 1, holes are drilled at both ends of the rammed earth wall 1, and then the holes at both ends of the rammed earth wall 1 are inserted and the surface is coated with cement mortar continue to build the brick column 2 and press the anchor bar 4 outside the rammed earth wall 1 into the brick column 2, and use cement mortar to fill the gap between the rammed earth wall 1 and the brick column 2 during...

Embodiment 3

[0047] Take the wall size of 5800mm (length) × 3900mm (height) × 720mm (thickness) as an example, such as figure 1 and figure 2 As shown, the rammed earth wall reinforcement method of the present embodiment comprises the following steps:

[0048] Step 1, building brick columns 2 for wrapping both ends of the rammed earth wall 1 at both ends of the rammed earth wall 1, and filling the gap between the rammed earth wall 1 and the brick columns 2 with cement mortar during the masonry process;

[0049]Step 2. When the brick column 2 is built to a height of 900 mm, holes are drilled at both ends of the rammed earth wall 1, and then anchor rods 4 coated with cement mortar are inserted into the holes at both ends of the rammed earth wall 1, and the masonry is continued The brick column 2 and the anchor rod 4 are located outside the rammed earth wall 1 and pressed tightly in the brick column 2, and the gap between the rammed earth wall 1 and the brick column 2 is filled with cement m...

Abstract

The invention discloses a rammed earth wall reinforcing method which comprises steps as follows: 1, building brick columns for covering two ends of a rammed earth wall at the two ends of the rammed earth wall; 2, when building the brick columns to the 1 / 5-1 / 4 height position of the rammed earth wall, punching holes in the two ends of the rammed earth wall, then inserting anchor rods with cement mortar spread on surfaces, and continuously building the brick columns; 3, when building the brick columns to the 1 / 3 height position of the rammed earth wall, digging grooves in two sides of the rammed earth wall and setting reinforcement mortar belts; 4, when building the brick columns to the 2 / 5-1 / 2 height position of the rammed earth wall, repeating the procedure of Step 2; 5, when building the brick columns to the 2 / 3 height position of the rammed earth wall, repeating the procedure of Step 3; 6, when building the brick columns to the 3 / 4-4 / 5 height position of the rammed earth wall, repeating the procedure of Step 2; 7, when building the brick columns to be flush with the rammed earth wall, finishing reinforcement of the rammed earth wall. The reinforcing method is simple, the construction cost is low, and the seismic performance of the rammed earth wall is improved significantly.

Description

technical field [0001] The invention belongs to the technical field of civil engineering raw earth building components, and in particular relates to a reinforcement method for rammed earth walls. Background technique [0002] The raw soil structure is not only easy to obtain local materials, convenient construction, and low cost; but also has good thermal performance, and has a good ability to adjust indoor temperature and humidity; at the same time, raw soil is a building material with low physical and chemical energy, and there is no waste disposal problem , The demolished building materials can be absorbed by the environment and will not have side effects on the environment. Raw earth structures are still vigorous after thousands of years of wind and rain, especially in the rural areas of western my country. It is still difficult to demolish and rebuild such a large number of houses with raw earth structures in a short period of time. To improve the problem of poor seismi...
