Description
Technical field
The invention belongs to hydroelectric project field, be specifically related to a kind of for concrete ledge flat inclined light quick-fried punching guide locating device provided.
Background technology
At present, in water power wall for underground power house beam open excavation, conventional construction method is the angle according to oblique rock bench, set up steel pipe scaffold of punchinging, angle of punchinging mainly adopts steel pipe to be fixed on scaffold, controlled by guiding steel pipe, the measure that the degree of depth of punchinging mainly adopts fixed length drilling rod, outside increase horizontal cross bar spacing.This construction method belongs to traditional approach, if it is lack of standardization to set up scaffold, then oblique angle of punchinging just is difficult to control, and affects rock wall beam trench quality; In addition, setting up scaffold needs a large amount of circulation materials, frequently takes and tears open, has both wasted material, also time-consumingly to have taken a lot of work.
Summary of the invention
The object of the invention is to overcome tradition to set up scaffold waste material, time-consumingly take a lot of work and be unfavorable for the drawback of quality control, provide a kind of make simple, simple operation, recycling number of times high, with low cost, be conducive to that the quick-fried Forming Quality of punchinging of concrete ledge flat inclined light controls guide locating device provided.
Technical scheme of the present invention is: concrete ledge flat inclined light is quick-fried punchinges and guide locating device providedly comprise guide-localization pipe, it is characterized in that being connected with symmetrically arranged removable and flexible up and down support body in guide-localization pipe bottom, this support body is made up of channel-section steel crossbearer, telescopic longitudinal holding pole and longitudinal fixed support, longitudinal holding pole vertically connects channel-section steel crossbearer, and longitudinal fixed support connects longitudinal holding pole and channel-section steel crossbearer.
Longitudinal holding pole is made up of 1# vertically-guided sleeve pipe, 2# vertically-guided sleeve pipe, 3# vertically-guided sleeve pipe and vertical pipes hold-doun nut and screw rod, cross cramp, 1# vertically-guided sleeve pipe, 2# vertically-guided sleeve pipe, 3# vertically-guided sleeve pipe are set with successively, cannula tip WELD NUTS is in sleeve pipe, nut connects expansion screw, the top welding cross cramp of screw rod, with fixed guide positioning pipe.Channel-section steel crossbearer is connected with level connection joint support and vertical, horizontal stiffened panel.Be connected with iron wire and gaily decorated basket nut between vertically-guided sleeve pipe and guide-localization pipe, there is guiding cap the termination of guide-localization pipe.
Adopt tradition to set up scaffold to punching, the biased difference in hole is+25cm ,-20cm, the maximum 30cm that backbreaks, maximum owing digs 20cm, and according to code requirement, crag should not be owed to dig, backbreak and should not be greater than 20cm, inclined-plane should be less than normal compared with design load with the actual value of horizontal sextant angle, but no more than 3 °.The present invention and tradition set up scaffold punching compared with there is following superiority:
1, need not repeat to take to tear scaffold open, 50% can be improved and to punching efficiency;
2, guide-localization pipe can be finely tuned, and the biased difference in hole of punchinging can be controlled to ± 5cm, and maximum out break is not more than 5cm, and the biased difference in hole reduces nearly about 75%;
3 inclined-planes are less than normal compared with design load with the actual value of horizontal sextant angle, and are no more than 1.5 °, and precision improves about 50%.
Accompanying drawing explanation
Fig. 1 is the quick-fried guide locating device provided structural representation of punchinging of concrete ledge flat inclined light of the present invention.
In figure, 1-channel-section steel crossbearer, 2-anchor pole, the longitudinal fixed support of 3-, 4-level connection joint support, 5-1# vertically-guided sleeve pipe, 6-2# vertically-guided sleeve pipe, 7-3# vertically-guided sleeve pipe, 8-vertical pipes screw cap hole, 9-vertical pipes hold-doun nut, vertical, the horizontal stiffened panel of 10-, 11-screw rod, 12-cross cramp, 13-guide-localization pipe, 14-guiding cap, 15-guide-localization pipe connected pipe, 16-gaily decorated basket nut, 17-iron wire, 18-set square, 19-concrete ledge.
Detailed description of the invention
Concrete ledge flat inclined light of the present invention is quick-fried punching guide locating device providedly connect into entirety by guide-localization pipe 13(by guide-localization pipe connected pipe 15), guide-localization pipe 13 bottom is connected with symmetrically arranged removable and flexible up and down support body and forms.This support body is made up of channel-section steel crossbearer 1, telescopic longitudinal holding pole and longitudinal fixed support 3, and longitudinal holding pole vertically connects channel-section steel crossbearer, and longitudinal fixed support 3 connects longitudinal holding pole and channel-section steel crossbearer.Longitudinal holding pole is made up of 1# vertically-guided sleeve pipe 5,2# vertically-guided sleeve pipe 6,3# vertically-guided sleeve pipe 7, vertical pipes hold-doun nut 9 and screw rod 11, cross cramp 12,1# vertically-guided sleeve pipe 5,2# vertically-guided sleeve pipe 6,3# vertically-guided sleeve pipe 7 are set with successively and are combined with each other, and are movable adjustable structure.Cannula tip welding vertical pipes hold-doun nut 9 is in sleeve pipe, and vertical pipes hold-doun nut 9 connects expansion screw 11, and the top welding cross cramp 12 of screw rod 11, with fixed guide positioning pipe.Channel-section steel crossbearer is connected with level connection joint support 4 and vertical, horizontal stiffened panel 10.Be connected with iron wire 17 and gaily decorated basket nut 16 between vertically-guided sleeve pipe and guide-localization pipe 13, gaily decorated basket nut carries out angle precise fine-adjustment location.There is guiding cap 14 termination of guide-localization pipe 13, the effect of guiding cap prevents from drilling rod from displacement occurring in the process of punchinging to cause inclined hole, also can control to punching the degree of depth (selecting drilling rod, the guide pipe degree of depth according to the degree of depth of punchinging, as long as reaches the design degree of depth of punchinging and namely cannot creep into) simultaneously.Adopt the anchor pole 2 channel-section steel crossbearer on abutment wall to be welded and fixed, ensure that guide locating device provided overall structure is indeformable.By drilling rod along the break-through of guide-localization pipe, then guiding cap pierced into along two ends of drill and tightens with guide-localization pipe, just can start to punching.Arrange a set square 18 at removable and flexible up and down support body and guide-localization pipe junction, set square 18 makes according to design concrete ledge cant chisel hole deviation angle.
After this guide locating device provided guarantee once mounting adjustment, a machine-team can be met and to punching needs.Cut a hole a round, first removed guide-localization pipe, channel-section steel base plate welding anchor pole, then adopted crane to hang to move on to next punch position, again install and fix and finely tune guide-localization pipe, this is guide locating device provided reuses.
