Description
Technical field
The present invention relates to one is used in and in existing building masonry panel, puts reinforcing bar slip casting by vertical boring and form rear increasing like configurations postStem stem constraining member strengthen wall ductility technology, increase stem stem Shockproof reinforcing method after being called for short in masonry panel, belong to seismic hardeningTechnical field.
Background technology
At present, Chinese existing house, the seismic hardening of agriculture residence start to start, existing house and 2000 before the eighties in last centuryThe a large amount of masonry structures of agriculture residence are in the past built without ring beam and construction column, have a strong impact on the required ductile performance of its masonry panel antidetonation, outerAdd constructional column and have following problem: difficulty of construction is large, concrete material loading difficulty, shuttering supporting difficulty, effectively strengthening construction outputRate is low---and pillar structure expense is well below external scaffolding expense, and building peripheral operation construction is dangerous large; Existing balcony exterior windowNeed tear down and reconstruct; Large on impacts such as existing building exterior tubing, guardrail, air-conditionings; Affect the outer facade effect of original building; Constructional column is difficult toVertical until top; Additional constructional column cannot be enhanced for inner side wall ductility, improves entirety for wider, long buildingDuctility DeGrain.
Summary of the invention
In order to address the above problem, the present invention proposes the rear stem stem Shockproof reinforcing method that increases in a kind of masonry panel. It is without destructionAppearance and interior decoration, all external procedure forms new antidetonation rod member, strengthens existing building wall ductility, can significantly improveWith the anti-seismic performance that solves existing building.
Technical scheme of the present invention is as follows:
After in a kind of masonry panel, increase stem stem Shockproof reinforcing method, comprise the former masonry panel of existing building, in former masonry panel, establishAfter being equipped with vertical body of wall, increase stem stem, after described body of wall, increase stem stem and comprise that being arranged on the elongated of the vertical middle position of former masonry panel erectsTo the polymer mortar of perfusion in the reinforcing bar that wears in boring, boring or steel strand wires and boring, adopt following steps to reinforce:
Step 1: according to increasing aperture and the hole spacing of stem stem after construction drawing design body of wall, and select rig, showField is made an on-the-spot survey, and unwrapping wire location, sets up scaffold, and erection construction platform sets up rig boring on existing building roof; BoreHole 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 wires;
Step 3: frame in boring is vertical placed in the middle by reinforcing bar or steel strand wires;
Step 4: end closure in boring, adopts grouting equipment and adopt High-Pressure Grouting Method injection of polymer mortar in boring;
Step 5: 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 wires 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 present invention sets up rig and is intending increasing stem stem position by the vertical boring of long distance in body of wall, so on existing building roofIn metapore, wear reinforcing bar or steel strand wires, then in hole, the stem stem constraining member of polymer injection mortar formation like configurations post strengthens existingConstruction wall ductility technology. When earthquake, will retrain wall body slit and carry out, strengthen body of wall globality. Reduce seismic force to superstructureThe destruction of causing.
The present invention strengthens existing building wall ductility technology, will retrain wall body slit and carry out when earthquake, strengthens body of wall globality, subtractsThe destruction that few seismic force causes superstructure. The present invention does not register one's residence and realizes the larger raising of Seismic Behavior of Masonry and speed of applicationHurry up, 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 brickWall, rectangular slab of stone masonry wall, rubble wall. The invention process has higher economic benefit and social benefit.

Detailed description of the invention
After in a kind of masonry panel, increase stem stem Shockproof reinforcing method, comprise former masonry panel 4, in former masonry panel 4, be provided withAfter vertical body of wall, increase stem stem 1, after described body of wall, increase stem stem 1 and comprise and be arranged on the elongated of former masonry panel 4 vertical middle positionsIn the reinforcing bar wearing in vertical boring, boring or steel strand wires 3 and boring, the polymer mortar 2 of perfusion, wherein, builds existingBuild roof and set up rig by the vertical boring of the interior long distance of former masonry panel 4, then in hole, wear reinforcing bar or steel strand wires 3,Then in hole, polymer injection mortar 2 forms the rear constraining member that increases stem stem 1 and strengthens former masonry panel 4 ductility technology. Vertical boringHole adopts special equipment, and bore position is placed in the middle on former masonry panel 4 widths, and boring size need be definite according to design,Between 40mm to 150mm. In hole, wear reinforcing bar or steel strand wires 3, if use reinforcing bar to adopt the multiple steel such as colligation overlap joint or weldingMuscle connected mode, length is identical with hole longitudinal length, reinforcing bar or steel strand wires 3 are positioned at boring cross section center. Note polymerization in holeThing mortar 2, polymer mortar 2 adopt high-pressure injection pump inject, need in the hole in full, polymer mortar 2 intensity according to design selectGet, rear increasing stem stem 1 constraining member finally forming has strengthened former masonry panel 4 ductility.
The former masonry panel of existing building 4 internal drilling positions are roughly selected referring to Fig. 1.
Design bore position, aperture and on-the-spot boring are noted destroying original structure precast floor slab 5, referring to Fig. 2.
Reinforcing step is as follows:
Step 1: select rig according to the aperture and the hole spacing that increase stem stem 1 after construction drawing design body of wall, carry out sceneMake an on-the-spot survey, unwrapping wire location, sets up scaffold, and erection construction platform sets up rig boring on existing building roof; BoringShould vertically penetrate the former masonry panel 4, floor 5 of existing building and basis 6 until the soil 7 of foundation bottom, rear increasing stem stem 1Position, hole, aperture and hole spacing all should according to Practical Project situation determine.
Step 2: hole and complete hole is cleaned out and penetrated reinforcing bar or steel strand wires 3, the model of reinforcing bar or steel strand wires 3, as usedReinforcing bar, reinforcing bar model is preferably HRB335.
Step 3: by vertical placed in the middle to reinforcing bar or 3 of steel strand wires.
Step 4: upper end closure, adopts grouting equipment polymer injection mortar 2 in hole, applying high voltage slip casting method.
