Abstract
The invention relates to a method for conducting anti-seismic reinforcement through later-arranged core columns in a masonry panel, and belongs to the technical field of anti-seismic reinforcement. The method comprises the steps of vertically drilling holes in a panel, arranging reinforcing steel bars in the holes in a penetrated mode, and enabling the holes to be filled with thick liquid to form the core columns. The method is the technology that drilling devices are erected on the outer side of an existing building, at the position where the core columns are planned to be built, long-distance horizontal drilling is carried out in a panel, the reinforcing steel bars are arranged in the holes in a penetrated mode, then the holes are filled with polymer mortar to form core column limiting rod pieces similar to construction columns, and therefore ductility of the panel of the existing building is reinforced. When earthquakes occur, and crack developing of the panel is limited, and integrity of the panel is strengthened. Damage of the anti-seismic force to upper structures is reduced. According to the method, the anti-seismic property of a masonry body can be greatly improved without entering a room, construction is simple, and the construction cost is low. The method is wide in application scope and suitable for solid brick walls, solid hollow blocks, cavity brick walls and boulder strip masonry walls.

At present, the existing house of China, the seismic hardening of agriculture residence start to start, before the eighties in last century, a large amount of masonry structure buildings of existing house and the agriculture residence before 2000 are 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, the concrete material loading is difficult, shuttering supporting is difficult, and effectively the strengthening construction output capacity is low---and the pillar structure expense is well below the 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 can't be enhanced for inboard wall ductility, for wider, long building, improves whole ductility DeGrain.
Summary of the invention
In order to address the above problem, increase the stem stem Shockproof reinforcing method after the present invention proposes in a kind of masonry panel.It is without destroying appearance and interior decoration, and all external procedure forms new antidetonation rod member, strengthens the existing building wall ductility, can significantly improve and solve the anti-seismic performance of existing building.
Technical scheme of the present invention is as follows:
Increase the stem stem Shockproof reinforcing method after in a kind of masonry panel, comprise the former masonry panel of existing building, increase stem stem be provided with vertical body of wall in former masonry panel after, increase the polymer mortar that stem stem comprises perfusion in the reinforcing bar that wears in the elongated vertical boring that is arranged on the vertical middle position of former masonry panel, boring or steel strand and boring after described body of wall, adopt following steps to be reinforced:
Step 1: according to after construction drawing design body of wall, increasing aperture and the hole spacing of stem stem, and select rig, carry out reconnaissance trip, the unwrapping wire location, set up scaffold, and the erection construction platform sets up rig boring on the existing building roof; Boring should vertically penetrate former masonry panel, floor and the basis of existing building until the soil of foundation bottom;
Step 2: hole complete hole is cleaned out and penetrated reinforcing bar or steel strand;
Step 3: by reinforcing bar or steel strand, frame in boring is vertical placed in the middle;
Step 4: end closure in boring adopts grouting equipment and adopts High-Pressure Grouting Method injection of polymer mortar in boring;
Step 5: the construction content is carried out an acceptance inspection.
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 the HRB335 reinforcing bar.
Beneficial effect:
The present invention sets up rig and is intending increasing the stem stem position by the vertical boring of long distance in body of wall on the existing building roof, then wear reinforcing bar or steel strand in hole, then in hole, the stem stem constraining member of polymer injection mortar formation like configurations post strengthens existing building wall ductility technology.To retrain wall body slit during earthquake and carry out, strengthen the body of wall globality.Reduce the destruction that seismic forces causes superstructure.
The present invention strengthens existing building wall ductility technology, will retrain wall body slit during earthquake and carry out, and strengthens the body of wall globality, reduces the destruction that seismic forces causes superstructure.The present invention does not register one's residence and realizes soon to the larger raising of Seismic Behavior of Masonry and speed of application, and construction is simple, and cost is low.Range of application of the present invention 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 invention process has higher economic benefit and social benefit.
