Description
Technical field
The present invention relates to building recovery technique fields, more particularly to a kind of assembled architecture prefabricated components surface reconditioning side
Method.
Background technique
In recent years, under the support energetically of country and relevant industrial department, assembly concrete building obtains fast-developing.
Though site operation and secondary operation is greatly reduced in assembly concrete building, solve the quality problems of many cast-in-place buildings.
But due to the factors such as industry development speed is fast, professional and industrial technology worker are deficient, supporting industries are immature, in prefabricated structure
In part production process, prefabricated components common quality defect happens occasionally, and influences the presentation quality of prefabricated components and using safe.How most
Common quality defect is eliminated and reduced to limits, guarantees that the quality inside and outside prefabricated components is the common objective of all participants.
In prefabricated components production, due to various aspects, such as concrete mix, cement quality, sand material specification, apply
The factors such as work technique, steam curing process, process control, means of transportation cause prefabricated components quality controllability poor, can generate various
Common quality defect: such as honeycomb, pitted skin, bubble, losing fangle, this kind of common quality defect are usually free of too big shadow to structure, building
Ring, belong to secondary mass defect, but in the more demanding project of appearance (such as clear-water concrete project), such issues that will be at
For main problem；As flatness is overproof, component geometric dimension deviation and other issues not necessarily causes fault of construction, but may
Influence building function and construction efficiency；It needs to repair component.
Therefore, a kind of assembled architecture prefabricated components surface repairing method that can solve the above problem how is designed, is
The project that the present inventor concentrates on studies.
Summary of the invention
The purpose of the present invention is to provide a kind of assembled architecture prefabricated components surface repairing method, restorative procedure is simple
It is easy to operate, it is high to the controllability of prefabricated components quality, it can prevent poor flatness, component geometric dimension deviation and other issues from producing
It is raw, it will not influence building function and construction efficiency.
To achieve the goals above, the present invention provides a kind of assembled architecture prefabricated components surface repairing method, wherein wrapping
Include following steps:
(1) removing surface step: surface faulty concrete is eliminated, makes surfacing, blows off surface dust；
(2) bottoming sub-step: face is repaired with the brushing of interface glue；
(3) honeycomb repairs step: after glue has slightly been done at interface, blocking honeycomb hole using renovation agent A, and scrape off excess surface
Renovation agent A, polish off redundance with sand paper in time after to be repaired dose of A hardening；
(4) pitted skin repairs step: is uniformly applied on repairing interface with deployed renovation agent B, component is integrally brushed to one layer and is repaired
Multiple agent B is polished flat component surface with sand paper in time after waiting renovation agents B to harden；
(5) losing fangle repairs step: the damage of small area directly uses renovation agent A to handle, and larger area damage uses renovation agent A
In conjunction with steps of processing: be compacted and plaster first carries out in two times, and skin patching material, which is shown up, to be struck off, then with hot trowel troweling
Surface.
Preferably, the step (1) further includes rejecting due to cutting faulty concrete and destroyed superficial layer process.
Preferably, renovation agent A in the step (3) is by following mass percent at being grouped as:
Glue: 21%~24%；
Cement A:30%~35%；
Cement B:19%~22%；
Washing dry sand: 15%~18%；
Binder: 2%~3%；
Defoaming agent: 2%~3%.
Preferably, the defoaming agent uses n-octytriethoxysilane.

Mud.
Preferably, renovation agent B in the step (4) is by following mass percent at being grouped as:
Glue: 26%~30%；
Cement: 28%~30%；
Dicalcium powder: 15.5%~16.5%；
Binder: 0.5%~1%；
Water: 25%~28%；
Toner: surplus.
Preferably, the binder uses hydroxypropyl methyl cellulose.
Preferably, when damaging repairing treatment to larger area losing fangle in the step (5), top after repairing with
Old concrete cemented side seam because resin mortar stays formed bonding it is bad when, it is secondary with hot trowel when resin mortar is gradually hardened
Catch up with extrusion real.
Preferably, when repairing bottom surface sheet cavity, resin mortar or material for repairing is first put on end template, then held out against
End template makes plateau using first formwork erection filling until resin mortar is squeezed out from four sides, to king-sized cavity, using low water ash
Than concrete, after concrete hardening demoulding along new-old concrete seam crossing slot, with resin mortar fill up seam crossing form it is whole
Body, repairing face and component original surface are equally smooth after repairing completely, finally scrape renovation agent A.
Preferably, the component is flat hang stacking after, cut off hanging ring, handle exposed reinforcement with antirust paint, and with renovation agent A
Paint surfaces.
After adopting the above scheme, assembled architecture prefabricated components surface repairing method of the present invention has the advantages that
(1) it can be solved using restorative procedure of the present invention because of concrete mix, cement quality, sand material specification, construction technology, steaming
Support honeycomb, pitted skin, bubble, the losing fangle etc. that the factors such as process, process control, means of transportation cause prefabricated components surface to generate
Problem, avoid this kind of common quality defect to structure, building in the more demanding project of appearance (such as clear-water concrete project)
It influences；It will not influence building function and construction efficiency；
(2) restorative procedure of the present invention is simple, easy to operate.
