Technical field
The invention belongs to the hydroelectric project field, be specifically related to a kind of for the concrete ledge flat inclined light quick-fried punching guide locating device provided.
Background technology
At present, in the water power wall for underground power house beam open excavation, conventional construction method is the angle according to oblique rock bench, set up the steel pipe scaffold of punchinging, the angle of punchinging mainly adopts steel pipe to be fixed on the scaffold, by the control of guiding steel pipe, the degree of depth of punchinging mainly adopts fixed length drilling rod, the outside to increase the spacing measure of horizontal cross bar.This job practices belongs to traditional approach, if it is lack of standardization to set up scaffold, the oblique angle of then punchinging just is difficult to control, affects the 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-consuming taking a lot of work.
Summary of the invention
The objective of the invention is to overcome tradition and set up scaffold waste material, the time-consuming drawback of taking a lot of work and being unfavorable for 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: the quick-fried guide locating device provided guide-localization pipe that comprises of punchinging of concrete ledge flat inclined light, it is characterized in that being connected with in guide-localization pipe bottom symmetrically arranged removable and flexible support body up and down, this support body is made of channel-section steel crossbearer, telescopic longitudinal holding pole and vertical fixed support, longitudinal holding pole vertically connects the channel-section steel crossbearer, and vertically fixed support connects longitudinal holding pole and channel-section steel crossbearer.
Longitudinal holding pole is comprised 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, the cannula tip WELD NUTS is in sleeve pipe, nut connects expansion screw, the top welding cross cramp of screw rod is with the fixed guide positioning pipe.Be connected with level connection joint support and vertical, horizontal stiffened panel at the channel-section steel crossbearer.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.
Adopting tradition to set up scaffold and punching, the biased difference in hole is+25cm ,-20cm, the maximum 30cm that backbreaks, maximum owes to dig 20cm, and according to code requirement, crag should not be owed to dig, backbreaking should not be greater than 20cm, and the inclined-plane is compared with design load with the actual value of horizontal sextant angle should be less than normal, but should not be above 3 °.The present invention and tradition are set up scaffold and are punchinged to compare and have following superiority:
1, need not repeat to take and tear scaffold open, can improve 50% efficient of punchinging;
2, the guide-localization pipe can be finely tuned, and the biased difference in the 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%;
It is less than normal that 3 inclined-planes and the actual value of horizontal sextant angle are compared with design load, and be no more than 1.5 °, and precision improves about 50%.
Description of drawings
Fig. 1 is the quick-fried guide locating device provided structural representation of punchinging of concrete ledge flat inclined light of the present invention.
Among the figure, 1-channel-section steel crossbearer, 2-anchor pole, the vertical 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-, the 11-screw rod, 12-cross cramp, 13-guide-localization pipe, the 14-guiding cap, 15-guide-localization pipe connected pipe, 16-gaily decorated basket nut, the 17-iron wire, 18-set square, 19-concrete ledge.
The specific embodiment
Concrete ledge flat inclined light of the present invention is quick-fried punching guide locating device providedly connect into integral body by guide-localization pipe 13(by guide-localization pipe connected pipe 15), guide-localization pipe 13 bottoms be connected with symmetrically arranged removable and up and down flexible support body consist of.This support body is made of channel-section steel crossbearer 1, telescopic longitudinal holding pole and vertical fixed support 3, and longitudinal holding pole vertically connects the channel-section steel crossbearer, and vertically fixed support 3 connects longitudinal holding pole and channel-section steel crossbearers.Longitudinal holding pole is comprised 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 interosculate, and are movable adjustable structure.Cannula tip WELD NUTS 9 is in sleeve pipe, and nut 9 connects expansion screw 11, and the top welding cross cramp 12 of screw rod 11 is with the fixed guide positioning pipe.Be connected with level connection joint support 4 and vertical, horizontal stiffened panel 10 at the channel-section steel crossbearer.13 of vertically-guided sleeve pipe and guide-localization pipes are connected with iron wire 17 and gaily decorated basket nut 16, and 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 is that the control drilling rod occurs to be shifted in the process of punchinging and causes inclined to one side hole, also can control simultaneously the degree of depth of punchinging (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 can't creep into).Adopt the anchor pole 2 channel-section steel crossbearers on the abutment wall to be welded and fixed, guarantee that guide locating device provided overall structure is indeformable.Drilling rod along the break-through of guide pipe positioning pipe, is pierced into guiding cap and tighten with the guide-localization pipe along two ends of drill again, just can begin to punching.In support body and guide-localization pipe junction removable and that stretch up and down a set square 18 is set, set square 18 is made according to design concrete ledge cant chisel hole deviation angle.
After this guide locating device provided assurance once mounting is adjusted, can satisfy the machine-team needs of punchinging.Cut a hole a round, removed first guide-localization pipe, channel-section steel base plate welding anchor pole, adopted again crane to hang and move on to next punch position, again installed and fixed and finely tuned the guide-localization pipe, this guide locating device provided recycling.
