Description
Technical field
The invention belongs to building structure calamity post-reinforcing recovery technique field, in particular to a kind of impaired brick mix structure punches wall
The restorative procedure of body.
Background technique
Brick mix structure is as important architecture structure form, and ownership is very big in China's town building, but this class formation
The earthquake fortification level of their location is usually lower, and brick mix structure easily destroys in earthquake.The reinforcing of brick mix structure after shake
It is of great significance with the recovery of function is used, restorative procedure is mainly reinforcing wall surface to improve wall after calamity at this stage
Seismic Bearing Capacity shows as increasing considerably the rigidity of structure in the form of " hard anti-", structure in earthquake is caused to absorb more
Brisance.Differentiation is not added frequently with integral reinforcing mode, to structural damage mode in such reinforcement means, to the destruction sequence of component
It is not required, the not reasonable economy of reinforcement means also has security risk.
Different degrees of destruction can occur in earthquake for the wall that punches in brick mix structure.And what common repair methods were faced
The disadvantage is that: construction speed is slow, and reinforcement amount is big, with a certain amount of wet construction, and does not account for two secondary earthquakes and is brought
Influence, damaged part often still destroys in lower secondary earthquake, can not embody structure ductility and destroy and multiple defence line
Reinforcing theory.Based on this problem, the punch reinforcement and repair method of wall of brick mix structure has much room for improvement, and realizes rapid, simple and direct, warp
Ji effectively reinforces target.
Summary of the invention
It punches wall fast repairing method the purpose of the present invention is to provide brick mix structure after a kind of shake, it is above-mentioned existing to overcome
There is the shortcomings that conventional method.The present invention is based on reinforced mesh holistic resistant behavior is good, property is worked together with mortar and brick block
The significant principle of energy, after removing the impaired wall in brick mix structure hole or more, reasonable Arrangement steel mesh while building new structural member
Piece is reliably connected inside wall, and with neighboring walls formation.Normal construction is not influenced, exceptional space is not take up, does not change knot
Structure functional characteristic is remarkably improved the anti-seismic performance for the wall that punches；Period of the invention is short, the scale of construction is small, cheap.
In order to realize above-mentioned purpose, the present invention adopts the following technical scheme:
Brick mix structure punches wall fast repairing method after shake, comprising the following steps:
Step 1: will shake back wall hole impaired wall up and down, from cracking by skin remove damaged building block, two sides are torn open
Except horse tooth trough until adjacent vertical wall edge, is retained, bottom is removed to this layer of collar tie beam, forms the former hole removed；
Step 2: the impurity on block surfaces and this layer of collar tie beam surface at cleaning horse tooth trough；In two sides horse tooth trough mouth mortar joint
Place from top to bottom leads to height every the double drilling of skin brick, is from top to bottom implanted into reinforcing bar along drill hole；
Step 3: after being laid with bedding mortar on collar tie beam, two sides reinforced mesh being horizontally placed on bedding mortar,
End and the bar splicing being exposed at other than horse tooth trough；It starts simultaneously at and lays bricks, place first piece of building block of the left and right sides in steel mesh
On piece, make mortar even adhesion building block using the hole of reinforced mesh, then along the vertical mortar joint of building block 90 degree be folded up steel
Muscle mesh sheet；Then the reinforced mesh side after bending continues to lay bricks；It so repeats to make reinforced mesh bending stepped and bury
In mortar between building block；The reinforcing bar being exposed at other than horse tooth trough is fully embedded in mortar by intermediate each skin when building；
Step 4: building to two panels reinforced mesh intersection, by two panels reinforced mesh where the building block of this skin vertical mortar joint
Place is welded, and is reversely bent two reinforced mesh later, is continued to build by skin bending reinforcing steel bar mesh sheet by step 3 method；
Step 5: it builds to by reinforced mesh and being previously implanted other than mortar joint close at the former hole wall height removed
Reinforcing bar reliably overlaps, then builds last skin building block, makes to build highly consistent with original wall body absolute altitude.
Further, further comprising the steps of: step 6: mending slurry cementation of fissures maintenance, and progress surface is smeared after reaching prescribed strength
Ash, the brick mix structure wall that punches quickly is repaired after completing shake.
Further, after clearing up impurity in step 2, block surfaces of polishing and collar tie beam surface can be with masonry sand
Starch reliable bond.
Further, drilling depth is 150mm in step 2.
Further, reinforcing bar length in corner is 200mm；Remaining each middle layer reinforcing bar length is 250mm.
Further, the lap of splice of reinforced mesh and reinforcing bar is 50mm.
Further, in step 3 and step 4, the strength grade of masonry mortar and brick setting is higher by 1 than former building materials
Grade.
Further, in step 3 and step 4, masonry way uses stretcher masonry method.
Further, after the completion of step 5, in the hole that original is removed in the masonry that is formed, reinforced mesh is in X-type and buries
Enter in mortar joint；The end of reinforced mesh is overlapped with corresponding embedded bar.
Further, reinforced mesh with a thickness of 4mm.
Punch wall hole damaged component up and down after present invention dismounting shake, reserves horse tooth trough and rake-out, is implanted into corner
End reinforcing bar is laid with bottom layer of the reinforcing steel mesh sheet and sufficiently overlaps with bottom layer of the reinforcing steel, utilizes rubbing for mortar and reinforced mesh hole edge
Power and cohesive force between the two are wiped, whole stress base is formed, is built in brick block while by reinforced mesh along wall diagonal line
Stepped mortar joint is bent by skin brick, when building to wall cover layer ends, by reinforced mesh and the steel being implanted into wall
Muscle sufficiently overlaps, and maintenance to the stipulated time can come into operation after completing building wall work.
Needed reinforcing bar length is 200mm, diameter 4mm at the horse tooth trough mortar joint of corner, and being implanted into length in mortar joint is 150mm,
50mm is reserved to be used as with reinforced mesh overlap joint.The specification for laying reinforced mesh is b*t=240mm*4mm, and b is width, and t is
Thickness；The hole of uniformly distributed 5*5mm on reinforced mesh.The strength grade of masonry mortar and brick setting requires to be higher by than former building materials
1 grade.Masonry way uses stretcher masonry method.
Compared with the existing technology, the invention has the following advantages:
The present invention as a kind of brick mix structure punch wall shake after repairing and reinforcement technology, be different from structure wall surface into
The method that row is reinforced enhances the shock resistance and ductility of component while not increasing wall stiffness.By reinforced mesh and brick
Reinforced mesh is layed in brick setting by masonry cooperative characteristic during wall reparation is built according to construction technology
Portion, and be reliably connected with neighboring walls formation, form the antidetonation system of multiple defence line.While realizing effective anti-seismic performance,
Speed of application obviously is accelerated, reinforcement cost is reduced, simplifies technical solution.The present invention has operability and generalization,
Significant economic and social profit can be brought.
