Description
Technical field
The utility model relates to a kind of wall body slit preparing structure, and particularly a kind of reinforced concrete wall runs through large fracture preparing structure.
Background technology
Along with the development of urban construction, many steel reinforced concrete structure buildings occur in various degree in the process of building and use, the crack of different pattern, the expansion in crack will cause the seepage of works, reduce the rigidity of works, durability and anti-seismic performance, along with further developing of crack, the safety of life and property of people may be threatened.Crack is the impaired important symbol of concrete structure, and especially the harmfulness of crosscutting concern is maximum.It is large that crosscutting concern has face width, destroy seriously to reinforcing bar and concrete binding power, weaken the feature that structural bearing capacity amplitude is large, crosscutting concern will pass through the Exposed reinforcement at place in harmful environment simultaneously, very easily cause the corrosion of reinforcing bar, reduce the durability of building.
Reinforced concrete wall fractue spacing is general more at random, and crack width is relatively tiny, and crack is also irregular in the trend of inside concrete, therefore just brings certain difficulty to the repairing in crack.For crack of different nature, the repair materials in crack is mainly resin and clay, and the most frequently used in resin have epoxy resin and modified epoxy resin, and the method for repairing mainly contains: surface preparation, grouting and completion method.(1) surface preparation: first with wire brush by concrete surface bristle, remove surface attachments, clean up with water, first use the embedding benefit concrete surface such as epoxy mortar, latex cement defect after drying, finally smear with selected repair materials.(2) high pressure grouting method: selected patching material is poured into inside, crack, reaches the object of the structural integrity that mends a split, durability and water proofing property.(3) completion method: crack is cleaned clean and cuts into channel-shaped, so that caulking material can tamping well.But the penetration of fracture of these method process is relatively all more shallow, to not only needing skin patching but also need the crosscutting concern of certain strengthening action to be just difficult to meet the demands.
Have a kind of method for repairing and mending and structure (ZL:201110395258.2) of building wall body slit at present, before employing cement mortar or powder of lacquer putty for use on are closed and are filled and led up building wall body slit, first on crack, polish groove along the length direction in crack by the interval every 3 ~ 20cm, then a peg is all used to be embedded into crack in each recess, prevented by the mode embedding peg in crack and reduce the distortion in crack, and then cover in the head of a nail end of cement mortar by peg and groove is filled and led up.Above-mentioned method for repairing and mending can play good effect under some specific operations, but the repairing of through crack for reinforced concrete wall, above-mentioned method for repairing and mending can not meet the demands, and structure repair intensity is low.
In sum, for effectively improving the structure repair intensity of body of wall, wall integrity and water resistance, needing a kind of easy construction of invention at present badly and can be effectively out of shape thus the reinforced concrete wall that crackle preventing produces again runs through large fracture preparing structure by crackle preventing.
Summary of the invention
The purpose of this utility model be to provide a kind of easy construction and can effectively crackle preventing distortion thus the reinforced concrete wall that crackle preventing produces again runs through large fracture preparing structure.
In order to realize above-mentioned technical purpose, the utility model have employed following technical scheme:
A kind of reinforced concrete wall runs through large fracture preparing structure, it is characterized in that: described preparing structure comprise dig along fracture strike in reinforced concrete wall two sides symmetry repairing groove, on reinforced concrete wall, crack bilateral symmetry draws screw rod that hole formed to pulling eye and the screw rod Screw arbor with nut at both-ends built-in to pulling eye, described repairing groove sets gradually hydro-expansive rubber thin slice, strengthening steel slab, waterproofing course and mortar repair layer from inside to outside; Hydro-expansive rubber sheet adhering is in repairing groove surrounding medial surface, and the strengthening steel slab of body of wall both sides is fixed by Screw arbor with nut at both-ends; Described preparing structure is arranged on reinforced concrete wall evenly and at intervals.
Further, the layout endokinetic fissure of described Screw arbor with nut at both-ends progressively becomes large to both sides spacing.
Described strengthening steel slab is also provided with peg of putting more energy in fissured central position.
Be symmetrically arranged with along seam repair layer of plastering between described adjacent preparing structure.
the utility model has following characteristics and beneficial effect:
(1) on reinforced concrete wall, crack bilateral symmetry draws screw rod that hole formed to pulling eye and the screw rod Screw arbor with nut at both-ends built-in to pulling eye, by being retrained securely in crack with Screw arbor with nut at both-ends, solves the distortion of the follow-up generation in crack, problem of Cracking.
(2) repair the hydro-expansive rubber thin slice arranged in groove and waterproofing course, improve reinforced concrete wall water resistance, prevent body of wall from again producing seepage, thus cause the corrosion of reinforcing bar, reduce the durability of building.
(3) contact position of reinforced concrete wall and upper and lower floor is provided with L-type steel plate, and the Screw arbor with nut at both-ends of L-type steel plate and preparing structure is welded and fixed, and improves the switching performance of body of wall and floor, improves its globality.
