Abstract
The invention discloses a repairing method and a structure for a building wall crack. At first, grooves (2) are polished in the crack along the length direction of the crack (1) at every 3-20 cm before the building wall crack is sealed, filled and leveled up through cement mortar or lacquer putty powder. Then, a metal nail (3) is used in each groove (2) to be embedded into the crack (1). The purposes of preventing deformation and narrowing the crack (1) are achieved by a manner that the metal nail (3) is embedded into the crack (1). At last, a nail head end of the metal nail is covered through the cement mortar (4) and the grooves are filled and leveled up. After the cement mortar is permanently set, the cement mortar or the lacquer putty powder is used for sealing, filling and leveling up rest wall building wall cracks. The repairing structure for the building wall crack not only has the advantages of being easy and convenient to construct, simple in structure and capable of preventing the crack from deforming continuously or narrowing the crack so as to prevent the crack from being produced again, but also has the advantages of being maintenance-free, low in construction cost, time-saving and labor-saving in construction and the like.
Description
Technical field
The present invention relates to a kind of method for repairing and mending and structure of building wall body slit, belong to the architecture structural crack technical field of construction.
Background technology
At present, in the architectural design technical field, between normal framework, shear wall or the shear force of frame wall construction of adopting, the infilled wall of rear block and the concrete column of first pouring into a mould, wall usually due to material at the inconsistent wall crazing that causes of contraction that expands with heat and contract with cold, causes under the moisture expansion and drying shrinkage condition; In addition, in masonry structure, often due to (blowing out) vibration or uneven settlement of foundation cause wall crazing, thereby affect the attractive in appearance of building and the use function.In the prior art, general repairing way for this class wall body slit is that the employing powder protects cement mortar or powder of lacquer putty for use on is filled and led up its sealing, fill and lead up the crack although adopt existing this mode temporarily to seal, but also can continue development due to the crack under from now on temperature in four seasons and humidity alternate cycles, existing this method for repairing and mending can not tackle the problem at its root, after crossing certain hour, its wall body slit also can manifest, and also needs to repeat repairing treatment.So existing mending building wall body slit mode or not ideal enough.
Summary of the invention
The objective of the invention is, thus provide a kind of easy construction, simple in structure, and can effectively prevent or reduce method for repairing and mending and the structure that Fracture Deformation prevents the building wall body slit that the crack produces again, to overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that the method for repairing and mending of a kind of building wall body slit of the present invention, comprise the method that adopts existing cement mortar or powder of lacquer putty for use on sealing to fill and lead up building wall body slit, but before adopting the sealing of cement mortar or powder of lacquer putty for use on to fill and lead up building wall body slit, first by polishing groove every the interval of 3～20cm along the length direction in crack on the crack, then be embedded into the crack with a peg in each groove, prevent and reduce the distortion in crack by this mode that embeds peg in the crack, and then cover in and groove is filled and led up with the head of a nail end of cement mortar with peg, after cement mortar final set, can adopt cement mortar or powder of lacquer putty for use on that the sealing of remaining building wall body slit filled and led up.
Above-mentioned crack is the crack of bearing wall and non-bearing wall body in brick mix structure, frame construction, shear wall structure, shear force of frame wall construction.
The preparing structure of a kind of building wall body slit of the present invention that builds according to the method described above is, this structure comprises the crack of construction wall, on the crack along the be interval with groove of its length direction every 3～20cm, be provided with a peg in being embedded into the crack in each groove, and the head of a nail end of peg protrudes from the bottom surface of groove and lower than the upper surface of groove, fill the cement mortar completely have the head of a nail end with peg to cover in each groove, be filled with cement mortar or powder of lacquer putty for use in remaining crack.
Above-mentioned groove be shaped as circle or rectangle, the diameter that it is circular or the width of its rectangle or length are 2～5 times of crack width; Depth of groove is 0.8～1.5 centimetre.
The diameter of above-mentioned peg is greater than 0.5～3 millimeter of the width in crack, and the length of peg is 2～12 centimetres.
Owing to having adopted technique scheme, the present invention embeds peg in wall body slit, by the mode that is embedded into the crack with peg, the crack is retrained securely, has effectively solved the follow-up contingent distortion in crack, problem of Cracking.After testing and proof of actual use, adopt the present invention patched crack the phenomenon in crack does not also occur again after through the time more than 2 years.Therefore, the present invention compared with prior art, thereby the present invention not only have advantages of easy construction, simple in structure, and can effectively prevent or reduce the crack and continue distortion and prevent that the crack from producing again, and the present invention also has the advantages such as non-maintaining, that construction cost is lower, construction is time saving and energy saving.The present invention is specially adapted to the repairing treatment to the bearing wall of masonry, framework, shear wall, frame structure and non-bearing wall body crack.
