Abstract
The utility model discloses a cutting structure, especially a cutting structure for processing is filled in crack. The utility model provides a do benefit to the closely knit a cutting structure for processing is filled in crack of later stage packing, extending to the internal crack of concrete, seting up in concrete body surface face and the cutting be connected with the crack including the concrete body, along concrete body surface face, the lower part of cutting cross section is the trapezoidal of big end down, and the upper portion of cutting cross section is the rectangle. The upper portion of cutting cross section is the rectangle, can fill in the later stage to obtain bigger surperficial lifting surface area when closely knit, and this backfill that makes the cutting bottom equally can be by the compaction, and there is not unsettled corner in the rectangle simultaneously, consequently is difficult to damagedly, the lower part of cutting cross section is trapezoidal, trapezoidal can fix with closely knit filler, avoid the filler to drop. The lower part of cutting cross section is isosceles trapezoid, can be so that the even symmetry of structure atress.
Description
Technical field
The utility model relates to a kind of groove structure, especially a kind of groove structure for frac-pack process.
Background technology
For distress in concrete, joint seal process must be carried out.Except surface preparation, for wider dark crack, filling method or chemical grouting method process must be adopted.Filling method construction precedence is: raggle-pointing sealing material-fill up cement mortar-brushing impervious material (can select cement based impermeable coating, epoxy resin, mylar or polyurethane etc.).Filling method process and grouting grouting can adopt the method for carving " V " shape groove or dovetail groove in seam face to carry out joint seal process, namely dovetail groove or " V " shape groove of wide, dark about 5 ~ 6cm is carved along seam, groove face cleaned up and coats epoxy base fluid after drying, then backfilling epoxy mortar.The opening of " V " shape groove is comparatively large, is not easy fixing filler; And trapezoidal groove structure construction is inconvenient, corner cracky, not easy-formation, be unfavorable for that later stage filling is closely knit.
Utility model content
Technical problem to be solved in the utility model is to provide and is a kind ofly beneficial to the later stage and fills the closely knit groove structure for frac-pack process.
The utility model solves the groove structure for frac-pack process that its technical problem adopts, comprise concrete bodies, along the surperficial crack extended in concrete bodies of concrete bodies, be opened in concrete bodies surface and the cutting be connected with crack, the bottom of cutting cross section is up-small and down-big trapezoidal, and the top of cutting cross section is rectangle.
Further, the bottom of described cutting cross section is isosceles trapezoid.
Further, the base angle that the bottom of cutting cross section is trapezoidal is a=60 ° ~ 70 °.
Further, described cutting inwall is provided with one deck sealing material along crack.
Further, described crack is connected to the center bottom cutting.
The beneficial effects of the utility model are: the top of cutting cross section is rectangle, can carry out obtaining larger surperficial lifting surface area when filling is closely knit in the later stage, this makes the backfill bottom cutting can be compacted equally, and rectangle does not exist unsettled corner simultaneously, is therefore not easy breakage; The bottom of cutting cross section is trapezoidal, trapezoidal backfill bottom cutting can be compacted, and can fix filler, avoids filler to come off.The bottom of cutting cross section is isosceles trapezoid, can make structure stress symmetrically.
Accompanying drawing explanation
Fig. 1 is cross sectional representation of the present utility model;
Fig. 2 is the schematic cross-section that the utility model completes when the first step is constructed;
Fig. 3 is the schematic cross-section that the utility model carries out when second step is constructed;
Component, position and numbering in figure: concrete bodies 1, crack 2, cutting 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, top in figure is upstream face, the utility model comprises concrete bodies 1, the crack 2 extended to along concrete bodies 1 surface in concrete bodies 1, be opened in concrete bodies 1 surface and the cutting 3 be connected with crack 2, the bottom of cutting 3 cross section is up-small and down-big trapezoidal, and the top of cutting 3 cross section is rectangle.Construction sequence of the present utility model as shown in Figures 2 and 3, first offers the groove of trapezoid cross section according to Fig. 2, the chamfered shape now with traditional is identical; Then carry out corner cut according to Fig. 3 to the top of the groove of trapezoid cross section, make the top of cutting 3 orthogonal, bottom is up-small and down-big trapezoidal.After cutting 3 is shaping, at cutting 3 inwall, one deck sealing material can be set along crack, then backfills epoxy mortar, then apply pressure at the opening part of cutting 3, make epoxy mortar filling closely knit.Top due to cutting 3 of the present utility model is rectangle, the opening part of namely cutting 3 is rectangle, this has larger size relative to traditional trapezoid-shaped openings, there is no acute angle simultaneously yet, therefore larger active area can be transmitted when applying pressure, its opening is not easy damaged simultaneously, can not affect overall structure.
Concrete, as shown in Figure 1, the bottom of described cutting 3 cross section is isosceles trapezoid.Isosceles-trapezium-shaped is symmetrical, and meanwhile, crack 2 is connected to the center bottom cutting 3, and this spline structure is more symmetrical, is conducive to reinforcing crack 2.Preferably, the base angle that the bottom of cutting 3 cross section is trapezoidal is a=60 ° ~ 70 °, and this angle had both been beneficial to firm backfilling material, transmission of pressure when being also beneficial to compacting, simultaneously convenient construction.
