Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
See Fig. 1 and Fig. 2, pressure ring used in the present invention comprises adjustable base 11 and pressing plate 12, and adjustable base 11 comprises iron plate 111 and screw rod 211 further, and in the middle of iron plate 111, have circular hole 112, four angles have fixing hole 113.One end of screw rod 211 puts in circular hole 112, and carries out two-sided welding with iron plate 111 and form complete adjustable base 11.
Circular hole 123 and adjustable waist-shaped hole 114 is had at the length direction two ends of pressing plate 12.During practice of construction, iron plate 111 must have product certificate, carries out eliminating rust, clearing up and brush two times rustproof paints after machining.Adjustable base 11 and pressing plate 12 also can machine in factory's customization.
According to the requirement of JGJ130-2011 " building operations fastener type steel pipe scaffold technical specification of security ", outrigger shaped steel Cantilever Beams tail end at two places and should to be fixed on reinforced concrete beam and plate above, and canned paragraph length should not be less than 1.25 times of cantilever span.The spacing of shaped steel Cantilever Beams is arranged according to builder's jack support body vertical rod advance, and each advance arranges one.See Fig. 3, before adjustable base 11 is pre-buried, first the PVC plastic sleeve pipe 115 highly a little more than slab thickness is packed into screw rod 211.Place adjustable base 11 respectively in the both sides of predetermined installation shaped steel Cantilever Beams 7, and fixed by the fixing hole 113 on adjustable base 11, namely complete the pre-buried installation work of adjustable base 11.
Water when smashing floor concrete 117, by concrete 117 vibration compacting, surfacing, guarantees the accuracy of pre-buried position.After concrete 117 waters, tower crane is by shaped steel Cantilever Beams 7 handling on flooring, and it is in place that shaped steel Cantilever Beams 7 is distributed to the position needing to install by installation personnel, and the length of then encorbelmenting as required carries out adjusting, locating.
After shaped steel Cantilever Beams 7 is had good positioning, circular hole 123 on pressing plate 12 and adjustable waist-shaped hole 114 are packed into the screw rod 211 being arranged in shaped steel Cantilever Beams 7 both sides by installation personnel respectively, use nut 116 fastening again, namely complete the installation anchoring work of shaped steel Cantilever Beams 7 and building.
See Fig. 4, suspension ring used in the present invention comprise a pair through hole 3 being arranged on connecting reinforcement both sides of iron plate 1, connecting reinforcement 2 and symmetry, and the axis of through hole 3 is vertical with iron plate 1, and the cross section of through hole 3 is circular.Connecting reinforcement 2 adopts the mode of welding to be fixed on the middle position of iron plate 1, and the two also can be one machine-shaping.Connecting reinforcement 2 and iron plate 1 must carry out eliminating rust, clearing up and brush two times rustproof paints.
According to the requirement of JGJ130-2011 " building operations fastener type steel pipe scaffold technical specification of security ", suspension ring can must come into operation after design checking is qualified, and in the present invention, the intensity of iron plate and iron plate and concrete contact area meet above-mentioned code requirement.Under the prerequisite meeting code requirement, iron plate of the present invention can be square, also can be circular, oval or rectangle, pentagon, hexagon or the uniform plate body of other thickness.
See Fig. 5, be embedded with the PVC plastic sleeve pipe 6 of inclination in the concrete structured beam 5 of last layer, sleeve pipe 6 keeps low inside and high outside state.Oblique pull wire rope 4 penetrates from sleeve pipe 6 lower entrance, and successively through after a pair through hole 3 of suspension ring, again returns from the eminence entrance of sleeve pipe 6.Preferably, through hole 3 is circular hole, and namely the cross section of through hole 3 is circular, and the axis of through hole 3 is vertical with iron plate 1 arranges.
See Fig. 6, it is fastening good that wire rope 4 passes the vertical rod 8 outer with outrigger shaped steel Cantilever Beams 7 and suspension scaffold respectively of latter two head of PVC plastic sleeve pipe 6, interior vertical rod 9 is connected, finally use wire clips (supporting with wire rope specification) 10 to tighten up, namely complete oblique pull wire rope 4 and draw anchor work by suspension ring and concrete structured beam 5.
During dismounting, first remove suspension ring.Wire clips 10 is loosened, extracts wire rope 4 out, namely complete the dismounting work of suspension ring.Remove pressure ring again.Turned on by nut 116 on screw rod 211, remove pressing plate 12, recycling tower crane hangs out shaped steel Cantilever Beams 7, then touches screw rod 211 top with hand hammer, i.e. dismountable adjustable base.After above-mentioned dismounting, with microdilatancy pea gravel concreten, hole to be provided is blocked.Hole to be provided due to suspension ring place is low inside and high outside, and therefore, the hole blocked can not seepage, so just completely eliminates the hidden danger of exterior wall leakage.
Suspension ring of the present invention can utilize the remaining iron plate leftover pieces in job site and bar dowel head to process.Before installing, repeat the link such as blanking, processing at every turn.Pressure ring of the present invention and suspension ring fitting operation convenient and swift, be easy to dismounting, use more than 50 times can be had enough to meet the need continuously.Effectively can increase work efficiency, both save construction cost, be conducive to environmental protection again.
