Abstract
The present invention discloses a method of repairing building cracks and simultaneously reinforcing structures. The method is capable of effectively repairing the building cracks, particularly partial cracks and non-beam-surface cracks, and the cracks are effectively repaired and the structures are simultaneously reinforced by utilization of the method that anchoring toothed plates are cooperated with tensioning of steel bars. The method comprises the steps of establishing the anchoring toothed plates at two sides of a structural crack section, fixing the toothed plates through expansion bolts and structural adhesive, connecting one ends of the steel bars to the toothed plate at one side and welding and fixing the steel bars, and fixing the other ends of the steel bars to the corresponding positions of the toothed plate at the other side after the other ends of the steel bars are tensioned. According to the method, cost of repairing the cracks can be reduced, work amount is little, period is short, and the method can be suitable for most conditions of building cracks.
Description
Technical field
The present invention relates to the concrete structure reinforcement field of civil construction project, the method for a kind of building tear reparation structural strengthening simultaneously specifically.
Background technology
Fabric structure crack can be caused by many reasons, and comprise maintenance not in time, material is defective, and foundation settlement tilts, overweight and earthquake etc.Building tear may appear at metope, and floor is beam face even, and these situations can form serious threat to the safety of building.But demolition blasting is not a kind of way of economy, the technology of repairing crack can reduce the risk even got rid of construction cracking and topple over, and reaches good technology and economic benefit.
In current prior art, repairing the main way in crack is reinforcement, comprises the reinforcing bar with beam face at the bottom of supplement beam, expands beam section, and the method for outsourcing reinforcing bar reinforcing near beam support, is all adopt to reinforce beam.But the drawback of this method is that cost is huge, and engineering amount of reform is large, for residential building and commercial building, can impact in the use in strengthening construction process Zhong Dui building, and effect not obvious.Another deficiency is, because acting surface is large, the crack effect therefore for local (as corner) is poor.
The immediate cause producing structural cracks produced tension stress on the interface, crack of inside configuration, the confining pressure that therefore as long as applying one is contrary with tension stress equal and opposite in direction direction between crack, just can eliminate fracturing reason, promote both crannied rehabilitations.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly repairs the method that building tear reinforces fabric structure simultaneously, can realize stitching reinforcement and repair effectively to building local cracks and non-beam facial cleft.
For achieving the above object, technical scheme of the present invention comprises the following steps: the first step, sets up anchoring tooth plate in the both sides in structural cracks interval, and tooth plate expansion bolt and structure glue are fixed; Second step, connects tooth plate with one end of reinforcing bar and is welded and fixed; 3rd step, after the other end stretch-draw of reinforcing bar, is fixed on the correspondence position of opposite side tooth plate.
In the aforesaid first step, only can occur that the one side in crack arranges tooth plate, also can at two-sided layout tooth plate.Effectively to apply Yue Bouquet power between crack, first must find an effective origin of force, therefore must set up the anchoring tooth plate bearing Zhe Yue Bouquet power.According to the difference of the character in crack, feature and the regularity of distribution, the arrangement of tooth plate is also different.For the not full face one side crack of communicating structure, only can occur that the one side in crack arranges tooth plate; For through full face two-sided crack, then can adopt two-sided layout tooth Sheet.
Aforesaid reparation building tear and structural strengthening method, the reinforcing bar in step 2 and step 3 also can adopt steel strand to replace, and carrys out the tooth plate that both sides are fixed in stretch-draw.
The method of the aforementioned reparation building tear stated and structural strengthening, the anchoring tooth plate described in it is T-shaped tooth plate or plane tooth plate.Aforesaid T-shaped tooth plate is a general T-shaped iron, and the base plate of tooth plate is holed, and web is carved tooth grain.
Compared with prior art, reparation building tear provided by the present invention reinforce simultaneously fabric structure method can for local little crack and non-beam facial cleft seam effectively repair, the effect of ruggedized construction can be realized, the supporting capacity of lift structure and shock resistance simultaneously.
Accompanying drawing explanation
This manual comprises 3 width accompanying drawings:
Fig. 1 is the floor map adopting method of the present invention to repair cracks on floor slab;
Fig. 2 is the sectional view of Fig. 1 along A-A.
Fig. 3 is the schematic diagram adopting method of the present invention to repair gable crack.
Component, component names and corresponding mark in figure: T-shaped tooth plate 1, plane tooth plate 2, reinforcing bar 3, crack 4, floor 5.
Detailed description of the invention
Embodiment 1: the building floor shown in accompanying drawing 1, the anti-negative reinforcement configured due to wall or the top surface of the beam at floor bearing place can not meet actual requirement, floor is caused to ftracture, floor is through tunneling boring bilateral cracking, therefore investigates the region in crack, according to method of the present invention, adopt the method for two-sided layout tooth plate: the first step, adopt plane tooth plate, by structure glue, plane tooth plate 2 is fixed on the collar tie beam side of gable, plane tooth plate is close to collar tie beam; In indoor, by the side, crack of expansion bolt just T-shaped tooth plate floor, every two T-shaped tooth plates 1 are corresponding, and the T-shaped tooth plate near gable side is corresponding with the plane tooth plate be fixed on gable; The tooth plate of identical correspondence is arranged too at the another side of floor.Second step, adopts
reinforcing bar 3, the two ends of reinforcing bar are embedded in the teeth groove of two corresponding tooth plates, and one end is fixed with solid welding, configuration 7 reinforcing bars between every two corresponding tooth plates.3rd step, does not have the other end stretch-draw of fixing reinforcing bar, is welded and fixed after crack is recovered.
Embodiment 2: shown in accompanying drawing 2 is building shear wall inner wall surface crack, fracture strike is vertical, and crack closeness is large, but the degree of depth is also little, therefore according to method of the present invention, adopt one side to arrange the method for anchoring tooth plate: the first step, arrange two vertical T-shaped tooth plates in the both sides of crack area, all fix with expansion bolt and structure glue.Second step, adopts steel strand, and steel strand one end is embedded in the teeth groove of corresponding two tooth plates, configures 5 steel strand altogether, and steel strand left end is first fixed on the tooth plate in left side.3rd step, the other end stretch-draw that steel strand are not fixed, be metope split a point compound, to be then fixed on other end tooth plate fixing.
Claims (4)
1. repair a building tear ruggedized construction method simultaneously, it comprises the steps: the first step, sets up anchoring tooth plate in the both sides in structural cracks interval, and tooth plate expansion bolt and structure glue are fixed; Second step, connects tooth plate with one end of reinforcing bar and is welded and fixed; 3rd step, after the other end stretch-draw of reinforcing bar, is fixed on the correspondence position of opposite side tooth plate.
2. the method for reparation building tear according to claim 1 and structural strengthening, in its first step, only can occur that the one side in crack arranges tooth plate, also can at two-sided layout tooth plate.
3. reparation building tear according to claim 1 and 2 and structural strengthening method, also can adopt steel strand to carry out the tooth plate that both sides are fixed in stretch-draw.
4. the method for reparation building tear according to claim 1 and structural strengthening, the anchoring tooth plate belonging to it is T-shaped tooth plate or plane tooth plate.
