Abstract

The invention relates to a method for repairing cracks on building wall, comprising: cleaning the cracks; slotting V-shaped slots on the cracks; preparing daub; filling the daub into the cracks; coating TB-999 anti-cracking waterproof glue on the surface of the repaired cracks and filling anti-cracking reinforced cloth into the repaired cracks. The method is used for repairing independent cracks on the exterior facings of concrete, plastering mortar and heat-insulating systems, and filling the gaps at the joints of self-insulating frame beams and filling walls, after repaired, the cracks has high bonding strength, good adhesion with base layers, high extension strength and good tenderness, does not crack, can close in accordance with the change of the cracks, thus the cracks are effectively controlled and covered.

Description

A kind of method for mending building wall body slit
Technical field
Patent of the present invention relates to the civil engineering technical field, the concrete method for repairing and mending that relates to a kind of building wall body slit.
Background technology
Concrete structure is big owing to its fragility, the often inevitable cracking that produces in engineering is used, and this cracking causes the decline of concrete structure watertightness, seepage, influences the application life of engineering, even can't normally use.This is the ubiquitous problem in building circle.The generation in crack mainly contains two big class reasons in the concrete structure, and a class is caused by distortion, comprises because of temperature humidity changes causing contraction, expansion, differential settlement etc.; Another kind of is that external load (dynamic and static load) direct stress causes that according to statistics, the former is a principal element, accounts for 75%.The analysis of causes that produces cracking from concrete structure is set about, and it is imperative to develop novel waterproofing materials.
At present, waterproofing materials is numerous, can be divided into flexible water and rigid waterproofing two big classes.In external for many years facts have proved that traditional flexible waterproof material such as coiled material and coating are though have flexibility characteristics, durability is also better, but a little less than basal plane concrete binding power, especially moist or have under the situation of infiltration and can't use at basal plane, should not make the waterproof of back side and moist basal plane.The rigidity cement group water-proofing material has the incomparable performance of flexible material and extensive use, but the most of metal surface water-tight of the cement group water-proofing material that generally uses agent at present, waterproof effect only acts on the surface, can not automatically, in depth be penetrated into inside configuration; Waterproof effect is not lasting, and produce the degenerative process that continues as time passes: in case waterproof coating is destroyed, waterproof ability is lost thereupon: easily cause concrete generation alkali weakness such as (AAR).Think from concrete structure cracking reason, engineering application characteristic and fire resistance characteristic, develop have the microscopic checks self-healing, penetrant crystalline, can be very necessary at the permanent cement base osmotic crystalline waterproof material of characteristics such as back side construction.
Summary of the invention
Technical problem to be solved by this invention is, overcomes problems of the prior art, and a kind of method for repairing and mending of building wall body slit is provided.
In order to address the above problem technical scheme of the present invention is such:
A kind of method for mending building wall body slit is characterized in that, comprises the steps:
The cleaning crack;
Open the V-type groove along the crack;
The preparation clay;
To crack pointing clay;
Mend the back fracture faces and be coated with folder cracking resistance reinforcement cloth in the anti-cracking waterproof glue.
In the step of described cleaning crack, require the crack not have loose, floating grey, the free of frost of nothing, the crack substrate surface is firm.
The width of described V-type groove: depth ratio was more than or equal to 2: 1, and its minimum-depth must not be less than 10mm.Clay is fully soaked in the crack, guaranteed the action space of clay, make clay better mend a split.
In the described preparation clay step, the clay for preparing forbids being with once more water to go into interior or thin up, after the clay preparation stirs, leaves standstill after 15 minutes and uses.
Described in the pointing clay step of crack, pick the wetting V-type groove of the clay that stirs with the undercoat brush earlier, with the direct pointing of the clay crack that stirs, make clay stick V-type groove both sides with putty knife raking both sides earlier during the pointing crack then, filling up in the middle of the groove last floating surface; When protruding phenomenon appearred in the V-type groove in solidification process, compacting got final product behind surface drying.
The both sides that described cracking resistance is strengthened cloth surpass the minimum 10mm of crack width, and the coating scope of anti-cracking waterproof glue surpasses cracking resistance and strengthens cloth both sides 5mm.Can fully guarantee the stability in crack like this, can also protect the crack after repairing simultaneously, prevent the crack that rainwater or damage are repaired.
Beneficial effect: method of the present invention is used for that outside finish independence cracks such as concrete, whitewash mortar, heat-insulation system are repaired and the filling in self-heat conserving Vierendeel girder and infilled wall interface slit etc., adhesion strength height after squeegeeing, has good adhesive with basic unit, the hot strength height, good toughness, do not ftracture after squeegeeing, can repair crack and filling pore automatically, effectively control and cover crackle according to the variation in crack.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of method for mending building wall body slit comprises the steps: to clean the crack; Open the V-type groove along the crack; The preparation clay; To crack pointing clay; Mend the back fracture faces and be coated with folder cracking resistance reinforcement cloth in the TB-999 anti-cracking waterproof glue.
In the step of described cleaning crack, can adopt instruments such as steel brush, the cleaning crack requires the crack not have loose, floating grey, the free of frost of nothing, and the crack substrate surface is firm.
The width of described V-type groove: depth ratio is decided according to actual conditions, but its width: and the degree of depth needs than more than or equal to 2: 1, and its minimum-depth must not be less than 10mm.Clay is fully soaked in the crack, guaranteed the action space of clay, make clay better mend a split.
In the described preparation clay step, clay has main component and ratio to be:
Portland cement 100
Methyl naphthalene sulfonic acid sodium condensation product 2-4
Aqueous silane/silicone emulsion (solid content) 10-20
Calcium hydroxide 12-20
Magnesium hydroxide 12-20
Swell soil 18-25
Quartz sand 60-80
Potassium aluminum sulfate dodecahydrate 18-25
Silicate of soda 4-6
Before the clay preparation is pulvis.During preparation, stir during preparation, leave standstill after 15 minutes and use, the clay for preparing forbids being with once more water to go into interior or thin up.
Described in the pointing clay step of crack, pick the wetting V-type groove of the clay that stirs with the undercoat brush earlier, with the direct pointing of the clay crack that stirs, make clay stick V-type groove both sides with putty knife raking both sides earlier during the pointing crack then, filling up in the middle of the groove last floating surface; When protruding phenomenon appearred in the V-type groove in solidification process, compacting got final product behind surface drying.
Technical performance that the present invention can reach such as following table:
Project Performance indications
Surface drying time (h) 6
Do solid work the time (h) 72
Extensibility (%) 45
