Description
Technical field
The present invention relates to a kind of technical field of buildings, the pre-applied force equipment in especially a kind of reinforcing wall crackAnd method.
Background technology
In present stage house, the building of brick mixed building body structure has accounted for sizable ratio, usually because material existsThe contraction of expanding with heat and contract with cold, cause under moisture expansion and drying shrinkage condition is inconsistent and cause wall crazing; In addition, tie at masonryIn structure, often because (blow out) vibration or uneven settlement of foundation cause wall crazing, thereby affect buildingAttractive in appearance and use function, the crack problem of masonry structure becomes the maximum problem of house customer complaint. Masonry belongs toFragile material, the existence in crack has reduced the quality of body of wall, as globality, durability and anti-seismic performance, andTo occupant in perception with cause psychologically harmful effect.
With this type of crack of pre-treatment, adopt joint filling method, mud jacking, outer screening sheet method and displacement method etc. more, andAccording to requirement of engineering, these Combination of Methods use. Adopt existing these modes to process crack, although can be temporaryCrack is filled and led up in time sealing, but because development also can be continued in crack under temperature in four seasons from now on and humidity alternate cycles,Existing these method for repairing and mending can not tackle the problem at its root, and cross after certain hour, and its wall body slit also can showExisting, even expand, also need to repeat to repair, be difficult to thoroughly process crack problem.
Pick seam and bury muscle method once as the method for traditional reinforcing masonry structure, owing to can not well controlling crackSize, be not added into " masonry structure Design of Reinforcement specification " GB50702-2011, make us that it's rather a pity.
At present, the solution also not had.
Summary of the invention
Technical assignment of the present invention is to provide the pre-of a kind of reinforcing wall crack for above-mentioned deficiency of the prior artAfterburning equipment and method, the pre-applied force equipment in this reinforcing wall crack and method have and can exist arbitrarilyOn many bars bolt, add accurate power, allow many bars bolt bear a certain amount of pulling force of wall section, by afterburning size,Control the size of crack occurrence; In the time that body of wall is stressed, many bars bolt and body of wall are worked jointly; With total cross-section steelMuscle net is reinforced thermal cracking and is compared, and greatly saves amount of reinforcement, buries compared with muscle method Ke Yiyou with traditional seam that picksEffect is controlled the size in crack, the feature that overall economic efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is:
