Abstract
The utility model relates to an anti-seismic reinforcing structure with a core column arranged later in a brickwork wall and belongs to the field of anti-seismic reinforcing technology. The anti-seismic reinforcing structure with the core column arranged later in the brickwork wall comprises the original brickwork wall of a building. The vertical wall core column arranged later is arranged in the original brickwork wall. The core column arranged later in the brickwork wall comprises a pass length vertical drill hole formed in the vertical middle position of the original brickwork wall, a reinforcing steel bar or a steel strand penetrating through the drill hole and polymer mortar poured into the drill hole. When an earthquake occurs, a wall restraint crack is expanded, so that the integrity of the wall is enhanced, and damage caused by earthquake force to the upper structure is reduced. The anti-seismic reinforcing structure with the core column arranged later in the brickwork wall is not installed in a house, the anti-seismic property of the brickwork wall is greatly improved, construction is simple, the manufacturing cost is low, the application range is wide, and the anti-seismic reinforcing structure is suitable for a solid brick wall, a solid or hollow building block, a rowlock brick wall and a boulder strip masonry wall.

At present, the existing house of China, the seismic hardening of agriculture residence start to start, before the eighties in last century, existing house and a large amount of masonry structures of agriculture residence before 2000 are built without ring beam and construction column, have a strong impact on the required ductile performance of its masonry panel antidetonation, there is following problem in additional constructional column: difficulty of construction is large, concrete material loading difficulty, shuttering supporting difficulty, effectively strengthening construction output capacity is low---and pillar structure expense is well below external scaffolding expense, and building peripheral operation construction is dangerous large; Existing balcony exterior window need be torn down and reconstructed; Large on impacts such as existing building exterior tubing, guardrail, air-conditionings; Affect the outer facade effect of original building; Constructional column is difficult to vertical until top; Additional constructional column cannot be enhanced for inner side wall ductility, improves overall ductility DeGrain for wider, long building.
Utility model content
In order to address the above problem, the utility model proposes the rear stem stem seismic reinforcing structure that increases in a kind of masonry panel.It is without destroying appearance and interior decoration, and all external procedure forms new antidetonation rod member, strengthens existing building wall ductility, can significantly improve and solve the anti-seismic performance of existing building.
The technical solution of the utility model is as follows:
After in a kind of masonry panel, increase stem stem seismic reinforcing structure, comprise the former masonry panel of existing building, be provided with vertical body of wall in former masonry panel after, increase stem stem, after described body of wall, increase the polymer mortar that stem stem comprises perfusion in the reinforcing bar that wears in the elongated vertical boring, boring that is arranged on the vertical middle position of former masonry panel or steel strand and boring.
Further, described bore diameter is 40mm-150mm.
Further, described elongated vertical boring is positioned at former masonry panel width middle position.
Further, described reinforcing bar or steel strand are positioned at boring cross section center.
Further, described reinforcing bar adopts overlap joint or is welded to connect form.
Further, described reinforcing bar adopts HRB335 reinforcing bar.
Beneficial effect:
The utility model sets up rig and is intending increasing stem stem position by the vertical boring of long distance in body of wall on existing building roof, then in hole, wear reinforcing bar or steel strand, then in hole, the stem stem constraining member of polymer injection mortar formation like configurations post strengthens existing building wall ductility technology.When earthquake, will retrain wall body slit and carry out, strengthen body of wall globality.Reduce the destruction that seismic forces causes superstructure.
The utility model strengthens existing building wall ductility technology, will retrain wall body slit and carry out when earthquake, strengthens body of wall globality, reduces the destruction that seismic forces causes superstructure.The utility model is not registered one's residence and is realized soon to the larger raising of Seismic Behavior of Masonry and speed of application, and construction is simple, and cost is low.The utility model range of application is applicable to solid brick wall, porous brick wall, hollow block wall, empty bucket brick wall, rectangular slab of stone masonry wall, rubble masonry.The utility model implements to have higher economic benefit and social benefit.
