Description
Technical field
The present invention relates to architectural engineering method for blocking, specially a kind of efficient shear wall through-wall bolt holes blocking side
Method.
Background technique
During shear wall construction, it is reinforcing template when wall form installs, is provided with split bolt (in wood in template two sides
During formwork erection, take out and reuse for convenience of split bolt, PVC casing is provided with outside split bolt), concrete pours
It builds completion, after form removal, Screw arbor with nut at both-ends is taken out, therefore form on shear wall multiple holes (split bolt on shear wall
Quincuncial arrangement is spaced about 450-550mm, general to determine by calculating).
Currently, usually mortar is little by little inserted hole with small ash bucket by worker when holes blocking operation, smash with reinforcing rod
In fact, closure process expends a large amount of artificial, and mortar waste is seriously, and more serious is closure leakiness, blocks process also not
Pvc pipe is taken, does not take out pvc pipe when if blocking, the mortar of closure is also less prone to bond, especially the hole on exterior wall, it is easy to
Cause hidden leakage defect and heat bridge phenomenon, when repairing also needs to reject exterior-wall heat insulation and exterior decoration layer, reprocesses difficulty, and need high-altitude
Operation.
Summary of the invention
There are time-consuming and laborious, mortar waste is serious, returns in order to solve existing shear wall through-wall bolt holes blocking by the present invention
Difficult and easy the problem of hidden leakage defect and heat bridge phenomenon occurs is repaired, a kind of efficient shear wall through-wall bolt holes blocking side is provided
Method.
The present invention is achieved by the following technical scheme: a kind of efficient shear wall through-wall bolt holes blocking method, is adopted
With following steps: a, shear wall concreting finish after reaching strength of mould stripping, and form removal simultaneously takes out through-wall bolt, form band
The bolt hole of pvc pipe；B, it chooses timber wedge drilling rod to be mounted on impact drill I, starts impact drill I, timber wedge drilling rod is gradually to bolt
It bores and moves in hole, after finding that pvc pipe loosens, close impact drill I switch, pvc pipe is taken out from bolt hole；C, to coagulation
After soil reaches some strength, chooses pyramidal alloy bit and be mounted on impact drill I, and on the conical surface of pyramidal alloy bit
It is fixed with barricade snap ring, later on impact drill I carries out drilling through work against bolt hole in exterior wall outer end, when barricade snap ring
It when being blocked by exterior wall end face, stops working, forms horn mouth in bolt hole outer end at this time；D, at the horn mouth of bolt hole
Spreading glue, and blocked bolt hole outer end is fixed on the prefabricated mortar block that horn mouth cooperates；E, note is then chosen
Sizing device carries out slip casting, and grouting device includes impact drill II, and the front end of impact drill II is clamped with hollow drill, the side of hollow drill
Be provided with several mouth sprays on wall, the front end of hollow drill is provided with extruding slurry mouth, the tail end of hollow drill be provided with communicate therewith and
The galvanized pipe connected by rotary joint, the upper end of galvanized pipe are provided with the funnel being threadedly coupled with it, and funnel top is provided with
Strip aluminium sheet is installed with the cored screw being threadedly coupled with it on strip aluminium sheet, and cored screw lower end is provided with and funnel bottom is pasted
The annular disc of conjunction, cored screw upper end is provided with rotating handles, and cored screw upper end is provided with the air pump communicated therewith；Note
When slurry, rotation rotating handles and cored screw open annular disc first, and interfacial agents are poured into funnel, and opening impact bores
II, interfacial agents enter hollow drill through galvanized pipe, and bolt hole is arrived in interfacial agents centrifugal atomization under the action of impact drill II
Inner wall is then switched off impact drill II, and after the interfacial agents final set of bolt hole inner wall, expansive cement mortar is poured into funnel,
It is again turned on impact drill II and opens air pump, expansive cement mortar is injected in bolt under the centrifugal force effect that hollow drill rotates
The surface of hole inner wall interfacial agents, and under the action of air pump, expansive cement mortar is starched mouth by hollow drill forward ends thereof and is squeezed
It is depressed at the center of bolt hole front end, blocks situation then according to mortar and exit hollow drill, at the same time, spray and squeeze
Expansive mortar completes slip casting；F, at last artificial filling exterior wall inner end bolt hole to closely knit, bolt hole closure is finished.
Mortar in the shear wall through-wall bolt holes blocking method in funnel can realize oneself of funnel by control handle
It is dynamic to open and close function；Horn mouth is drilled out on shear wall using pyramidal alloy bit, is blocked with prefabricated mortar block, is extended
Water route, prevents rain leakage；It is dynamic using the brill at full speed of core drilling, the cohesive force of interfacial agents and shear wall is enhanced, simultaneously
The cohesive force of mortar and interfacial agents is enhanced, mortar is squeezed using air pump, fills and reserved when hollow drill exits in bolt hole
Hole, the mortar so blocked is firmly bonded with shear wall, blocks closely knit, overcomes existing shear wall through-wall bolt hole envelope
It is stifled to there are problems that time-consuming and laborious, mortar waste is serious, reprocess difficult and hidden leakage defect and heat bridge phenomenon easily occurs.
Shear wall through-wall bolt holes blocking method of the present invention can be conveniently by bolt sealing hole, effectively
Construction efficiency is improved, and is effectively controlled the dosage of mortar, while having the effect of that closure is closely knit, ensure that hole
Quality is blocked, the generation of hidden leakage defect and heat bridge phenomenon has thoroughly been prevented, there is simple process, save the cost, prevent to do over again
Repair phenomenon, easy to operate and low to worker operation skill requirement advantage.
