Problems solved by technology
[0002] At present, the seismic reinforcement of existing residential buildings and farm houses in China has started. During the reinforcement period of existing residential buildings, the common people are not willing to allow construction at home. Reinforced concrete short-leg walls) need to go through the building, such as steel tie rods, etc., which need to be reinforced at home. The lack of steel tie rods seriously affects the integrity of the outer jacket reinforcement technology

Embodiment Construction
[0025] A kind of anti-seismic strengthening construction method of shortening limb walls and steel tie rods in the back of existing buildings, see Figures 1 to 5 As shown, including the original longitudinal wall 6 and the original horizontal wall 7, the original horizontal wall 7 is provided with a full-length horizontal drilling hole, steel tie rods 2 are inserted in the holes, polymer mortar 5 is injected in the holes, and drilling equipment is erected outside the existing building At the proposed location of the steel tie rod 2, a long-distance horizontal drilling is carried out in the original transverse wall 7, and then the steel tie rod 2 is pierced in the hole, and then polymer mortar 5 is injected into the hole to form the steel tie rod 2 restraining member to enhance the integrity of the masonry building. Seismic reinforcement technology. Special equipment is used for horizontal drilling, and the drilling position is located in the horizontal center of the original ...

The invention relates to an earthquake resistant reinforcing construction method of subsequently increasing short limb walls and steel pulling rods in an existing building, and belongs to the technical field of earthquake resistance and reinforcement. The method includes erecting drilling equipment on the outer side of a masonry building transverse wall so as to horizontally drill holes for long distance in positions for steel pulling rods arrangement in the wall; then passing steel bars into the holes, and then injecting polymer mortar in the holes to form steel pulling rod limiting members, strengthen subsequently added short limb walls and enhance integrity of the masonry building. Crack extension on the wall during earthquake is limited, wall integrity is enhanced, and damages of the upper structure by earthquake force are reduced. According to the method, masonry earthquake resistance is improved greatly, construction is simple, cost is low, application range is wide, and the method is adaptable to solid brick walls, porous brick walls, hollow brick walls, hollow block walls, stone masonry walls and rubble walls.
Description
technical field [0001] The invention relates to an anti-seismic reinforcement construction method, in particular to an anti-seismic reinforcement construction method for shortening limb walls and steel tie rods behind an existing building, and belongs to the technical field of anti-seismic reinforcement. Background technique [0002] At present, the seismic reinforcement of existing residential buildings and farm houses in China has started. During the reinforcement period of existing residential buildings, the common people are not willing to allow construction at home. Reinforced concrete short-leg walls) require building-through steel tie rods and other home reinforcement construction technologies that are difficult to realize, and the lack of steel tie rods seriously affects the integrity of the jacket reinforcement technology. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention proposes an anti-seismic reinforcement...
