Abstract
A concrete crack repairing structure comprises an inverted triangle glue injection groove, a seal-capping adhesive tape and an epoxy daub layer, wherein the inverted triangle glue injection groove is formed in a crack of a concrete layer; the apex angle of the inverted triangle glue injection groove is connected with the crack; the seal-capping adhesive tape is arranged above the inverted triangle glue injection groove and is pasted and fixed on the concrete layer on the two sides of the inverted triangle glue injection groove; the seal-capping adhesive tape is coated with the epoxy daub layer sealing the seal-capping adhesive tape on the concrete layer. The concrete crack repairing structure can effectively prevent crack blockage due to misoperation of daub during the crack sealing process so as to form a smooth glue saluting pouring passage, improve glue injection efficiency, and ensure repairing quality.
Description
Technical field
The utility model relates to a kind of repair structure of distress in concrete.
Background technology
Steel concrete is the most large building structural materials that the mankind use, and has been widely used in the engineerings such as house, road, bridge, water conservancy project, Hai Gong.Yet concrete is because of shortcomings such as fragility are large, tensile strength is low, the effect due to surrounding environment in use procedure tends to inevitably produce crack.When crack surpasses Criterion restriction, can accelerate structural damage, the application life of shortening structure, so fracture repairs, and to improving the durability of concrete structure, plays very important effect.
In the middle of existing method for repairing and mending, surface sealing method and filling Sealing Method are that fracture table mouth seals, and prevent extraneous hazardous substances impouring, have improved structure durability.Pressure grout method and injection have all been injected into repairing glue in chamber, crack, except having improved durability, the rigidity of cracking member are had to certain repairing effect.Dark and sinuous crack is generally adopted to pressure grout method reparation, but often not good to this type of less crack the method repairing effect of width.The main cause that affects repairing effect is, crack is affected by the factors such as the vibration, normal erosion of airborne dust, structure all the year round, in its gap, often there are some silt impurities, and because crack width is little, in the process of construction, these impurity are not easy to clean out, being pressed into of epoxy mortar while adding joint seal, often causes glue injection channel by shutoff, has affected slip casting effect.
Utility model content
The purpose of this utility model is to provide a kind of can effectively preventing because clay misoperation causes crack, to stop up in joint seal process for the deficiencies in the prior art, improves the repair structure of the distress in concrete of injecting glue efficiency, assurance repairing quality.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of repair structure of distress in concrete, comprise del injecting glue groove, capping adhesive tape and epoxy glue mud layer, described del injecting glue groove is opened in the place, crack of layer of concrete, the drift angle of described del injecting glue groove is connected with crack, described capping adhesive tape is arranged on del injecting glue groove top and is pasted and fixed on the layer of concrete of del injecting glue groove both sides, and described capping adhesive tape is wrapped with by capping adhesive tape sealing the epoxy glue mud layer on layer of concrete.
Owing to adopting said structure, crack of the present utility model repair structure, the following advantage of tool:
1) because del injecting glue groove outside opening is wider, therefore can store more glue, and up big and down small, be convenient to glue to flow in fracture, improved the degree of depth of repairing, can have better repair efficiency to active fissure.
2) capping adhesive tape is arranged between epoxy glue mud layer and del injecting glue groove, can effectively prevent that in joint seal process, the epoxy mortar in epoxy glue mud layer stops up crack, improves injecting glue efficiency, guarantees repairing quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As shown in Figure 1, the repair structure of distress in concrete, comprise del injecting glue groove 4, capping adhesive tape 2 and epoxy glue mud layer 3, described del injecting glue groove 4 is opened in 5 places, crack of layer of concrete 1, the drift angle of described del injecting glue groove 4 is connected with crack 5, described capping adhesive tape 2 is arranged on del injecting glue groove 4 tops and is pasted and fixed on the layer of concrete 1 of del injecting glue groove both sides, and described capping adhesive tape 2 is wrapped with by capping adhesive tape sealing the epoxy glue mud layer 3 on layer of concrete.
Adopt the repair structure of above-mentioned distress in concrete, Specific construction step is as follows:
1) investigation of cracks
Investigate thoroughly the character in crack and the length in crack, width, the degree of depth, the situation of moving towards, run through and leak comprehensively.
2) crack treatment
For effective joint seal, along crack cutter del injecting glue groove 4, notch A/F is that 10mm, the degree of depth are 15mm left and right.With instruments such as wire brushes, remove the dirts such as dust, scum silica frost and unconsolidated formation on distress in concrete surface, brush away floating ash, will be along seam both sides 5cm scope wiped clean with alcohol.
3) paste capping adhesive tape 2
By capping adhesive tape 2, along fracture strike, paste, capping adhesive tape 2 can adopt pressure sensitive adhesive tape, and capping adhesive tape 2 width are about 3cm, in glue-injection base position, reserve perfusion channel.After completing, should check, the stickup of capping adhesive tape 2 is critical processes of work progress, directly affects cementation of fissures effect.
4) paste glue-injection base
The wider place in staggered place, crack and fracture tip in crack arrange grouting nozzle, the spacing of grouting nozzle is determined according to Size of Crack, trend and form of structure, during the wide 0.3-0.5mm of general seam, grouting nozzle spacing is 30-50cm, and stock inlet and exhaust opening (or grout outlet) are set on a crack.
5) joint seal
Epoxy mortar is used in the sealing in crack, with putty knife, along crack toward overcoating, scrapes the rear epoxy mortar of evenly smearing the about 1-2mm of thick layer, wide 5cm, notes preventing minute bubbles and poorly sealed.
6) joint seal check
Generally, within after epoxy mortar joint seal 1-2 days, can carry out leak test check, to check sealing effectiveness and the perforation situation in crack.
7) slip casting
Slip casting on a crack can be from shallow to deep, from bottom to top, and by end to end.When last grout outlet plastic emitting and plastic emitting speed keep stable after, then keep pressure injection can stop slip casting about 10 minutes.
8) slip casting effect check
After slip casting finishes, should check construction effect and quality, all have defective situations such as leakiness, should carry out after-teeming.
Owing to having adopted this structure, by carry out capping with pressure sensitive adhesive tape after the cutter del injecting glue groove of crack, carry out again epoxy mortar sealing, slip casing by pressure fracture is repaired, can prevent that epoxy mortar from entering in del injecting glue groove, effectively prevent that epoxy mortar from stopping up crack, guarantee that glue has broad flow channel, width is expanded after seam compared with little and dark and sinuous crack, in silt impurity in having cleared up seam chamber, top layer, also increased glue flow channel, guarantee the unimpeded of glue injection channel, can make flow resistance reduce, injecting glue section internal pressure is more stable, width is being used to reparation glue of the same race compared with little and dark and sinuous crack, under identical injection pressure effect, the degree of depth that adopts the method to repair is larger, more obvious to rigidity of structure repairing effect.
