Abstract
The present invention relates to segmentation cutting method and the device thereof of a kind of prestressed concrete circular hole slab before concrete setting, before concrete setting, adopt two wear-resistant circular saw bits that rotate at a high speed of wet cutter, link muscle as the depth of cut cutting of wetting not cut to, after having cut the concrete in the middle of the twice edge of a knife is cleaned out.It is smooth smooth to adopt the present invention to cut the preceding circular hole slab otch of initial set, very little along the tangent plane deviation, and the both sides concrete be can be considered no disturbance, and the problem that solves the termination irregularity for the cutting of the segmentation before the circular hole slab initial set has obtained very big breakthrough.
Description
The invention belongs to segmentation cutting method and the device thereof of prestressed concrete circular hole slab before concrete setting.
Adopting extrusion forming process to produce prestressed concrete circular hole slab at present is that long line is worked continuously, and this just brings the segmentation cutting problem of circular hole slab.Press the designing requirement of circular hole slab atlas, the two ends of the circular hole slab after the cutting must be left certain-length and link muscle, therefore can only carry out the segmentation cutting before concrete setting.Domestic circular hole slab to extrusion forming process production mostly adopts manual segmentation cutting, also have and adopt water under high pressure cutting and square panel vibration down inserting type wet method to cut, these several segmentation cutting methods all can not be cut stone, and the termination of circular hole slab is rough and uneven in surface, the concrete of the otch loosening and poor plate of reinforcing bar of the head that causes plate that is disturbed does not meet circular hole slab standard quality requirement in cutting process.
The present invention proposes a kind of extrusion modling circular hole slab is carried out the segmentation cutting before concrete setting method and device thereof, solved the termination quality problems after the segmentation of extrusion modling circular hole slab is cut effectively.Before concrete setting, adopt two of the wet cutter wear-resistant circular saw bits of rotation at a high speed, link muscle as the depth of cut cutting of wet not cut to, concrete after having cut that the twice edge of a knife is middle cleans out.
Fig. 1 is the structural representation of wet cutter.

The stringing post, 2. travel switch, 3. slide plate, 4. motor, 5. belt housing, 6. slitter shaft, 7. bearing block, 8. saw blade, 9. safety guard, 10. stacked switch, 11. electronic boxs, 12. stringing steel wires, 13. handles, 14. motor, 15. tail wheels, 16. gearboxes, 17. travel switches, 18. fine setting levers, 19. road wheels, 20. positioning wires, 21. are regulated nuts, 22. fore-stocks, 23. guide rails, 24. front beams, 25. leading screws, 26. concrete, 27. and are linked muscle.
Wet cutter is mainly by cutting knife, mechanical feeding device and regulate support and form, and cutting knife is to be made of two wear-resistant circular saw bits 8, the spacing of two circular saw bits 8 can rely on to be fixed on splits pad adjustment on the saw blade axis.Mechanical feeding device is made of motor 14, gearbox 16, leading screw 25, slide plate 3 and guide rail 23, saw blade 8 is fixedlyed connected with slide plate 3 respectively with driving saw blade turning motor 4, slide plate 3 is fixed on the guide rail 23, under the driving of motor 14, gearbox 16, leading screw 25, slide plate 3 can move on guide rail 23.
Regulate support and form, on road wheel 19 and fore-stock 22, be equipped with respectively and can regulate fine setting lever 18 and the adjusting bolt 21 that guide rail 23 makes its horizontal lifting by road wheel 19, guide rail 23, front beam 24, fore-stock 22.
Be discussed in detail below below in conjunction with the wet cutting method of wet cutter concrete circular hole slab:
At first according to the circular hole slab atlas to linking the length requirement of muscle 27, adjust the pad between two circular saw bits 8, adjust its distance, if two cutterhead spacings are adjusted to 100 millimeters, on the precut circular hole slab that continuously produces, design Cutting Length with preseptum adds that the distance of a wet cutter positioning wire 20 and a side blade is standardized line of length for 50 millimeters, promoting wet cutter then makes precut circular hole slab between the fore-stock 22 and road wheel 19 of wet cutter, the positioning wire 20 of wet cutter is aimed at this line, be not cut and be as the criterion with the muscle 27 that links that guarantees circular hole slab, determine depth of cut, fine setting lever 18 and the adjusting bolt 21 on the fore-stock 22 adjusted on the road wheel 19 make guide rail 23 horizontal liftings, adjust the degree of depth of cutting.
Press the starting button on the electronic box 11, motor 4 makes two circular saw bit 8 rotations at a high speed, press the feeding button again, motor 14 is through gearbox 16, leading screw 25 drives slide plate 3 and moves forward on guide rail 23, because two circular saw bits 8 and motor 4 all are fixedly mounted on the slide plate 3, two the at a high speed circular saw bits 8 of rotation cuttings of under the drive of slide plate 3, wetting, because the linear velocity of cutterhead circumference is very high, to being wrapped in the cutting that rubs of stones in the concrete 26, produce high humidity in incision, stone is cut, and cutting knife fixed speed auto-feed more accurately cutting reaches the concordant requirement of tangent plane.Owing to adjusted depth of cut in advance, so when advancing cutting, blade wheel rim lower edge and ground remain certain distance, guarantee that linking muscle 27 is not damaged (as shown in Figure 3), after cutting finishes, slide plate 3 is run into travel switch 2, slide plate 3 drives still in the cutting knife reposition of rotation, bump travel switch 17 after, slide plate 3 stops to move, saw blade 8 stops the rotation simultaneously, and cutting finishes.Because wet cutter is provided with cutting and positioning device, guarantees the perpendicularity of the edge of a knife and plate length direction, withdraws from wet cutter, the concrete in the middle of two road junctions of two cutterheads cutting is cleaned out, cleaning back circular hole slab section is as shown in Figure 4.
Adopt the circular hole slab before the present invention cuts initial set, otch is smooth smooth, and is very little along the tangent plane deviation, and the both sides concrete is not had disturbance, and the problem that solves the termination irregularity for the cutting of the segmentation before the circular hole slab initial set has obtained very big breakthrough.
