Step includes iron plate 111 and screw rod 211, circular hole 112 is provided with the middle of iron plate 111, four angles have fixing hole 113.Screw rod
211 one end is put in circular hole 112, and forms complete adjustable base 11 with the progress two-sided welding of iron plate 111.
Circular hole 123 and adjustable waist-shaped hole 114 are had at the length direction two ends of pressing plate 12.During practice of construction, iron plate
111 must have product certificate, are derusted, cleared up after machining and two times antirust paints of brush.Adjustable base 11 and pressing plate 12
Also it can be machined in factory's customization.
According to JGJ130-2011《Construction fastener type steel pipe scaffold technical specification of security》Requirement, outrigger shaped steel
Encorbelmenting tail beam should be at two and the above is fixed on reinforced concrete beam and plate, and canned paragraph length is no less than length of encorbelmenting
1.25 times of degree.The spacing of shaped steel Cantilever Beams is set according to builder's jack support body vertical rod advance, and each advance sets one.Ginseng
See Fig. 3, before adjustable base 11 is pre-buried, the first PVC plastic sleeve pipe 115 that height is slightly above slab thickness is first packed into screw rod
211.Adjustable base 11 is placed respectively in the predetermined both sides for installing shaped steel Cantilever Beams 7, and passes through the fixing hole on adjustable base 11
113 fix, that is, complete the pre-buried installment work of adjustable base 11.
Pour when smashing floor concrete 117, by the vibration compacting of concrete 117, surfacing, it is ensured that pre-buried position it is accurate
Property.After concrete 117 is poured, tower crane is by the handling of shaped steel Cantilever Beams 7 to flooring, and shaped steel Cantilever Beams 7 are distributed to by installation personnel
Need position to be mounted in place, the length of then encorbelmenting as needed is adjusted, positioned.
After shaped steel Cantilever Beams 7 are had good positioning, installation personnel distinguishes the circular hole 123 and adjustable waist-shaped hole 114 on pressing plate 12
Pack into the screw rod 211 of the both sides of shaped steel Cantilever Beams 7, then fastened with nut 116, that is, complete shaped steel Cantilever Beams 7 and building
Installation anchoring work.
Referring to Fig. 4, suspension ring used in the present invention include iron plate 1, connection reinforcing bar 2 and symmetrical be arranged on and connect reinforcing bar two
A pair of through holes 3 of side, the axis of through hole 3 is vertical with iron plate 1, and the cross section of through hole 3 is circle.Reinforcing bar 2 is connected using welding
Mode is fixed on the position in the middle of iron plate 1, and the two can also be integrally machined shaping.Connection reinforcing bar 2 and iron plate 1 must be removed
Rust, cleaning and two times antirust paints of brush.
According to JGJ130-2011《Construction fastener type steel pipe scaffold technical specification of security》Requirement, suspension ring are necessary
Through design checking it is qualified after can come into operation, in the present invention, the intensity of iron plate and iron plate are to meet above-mentioned with concrete contact area
Code requirement.On the premise of code requirement is met, iron plate of the invention can be square or circular, oval
Shape or rectangle, pentagon, hexagon or other plate bodys in uniform thickness.
Referring to Fig. 5, inclined second PVC plastic sleeve pipe 6, the second PVC plastic are embedded with the concrete structured beam 5 of last layer
Material sleeve pipe 6 keeps low inside and high outside state.Oblique pull steel wire rope 4 is penetrated from the lower entrance of the second PVC plastic sleeve pipe 6, and is worn successively
After a pair of the through holes 3 for crossing suspension ring, returned again from the eminence entrance of the second PVC plastic sleeve pipe 6.Preferably, through hole 3 is circular hole,
I.e. the cross section of through hole 3 is vertically arranged for circle, and the axis of through hole 3 with iron plate 1.
Referring to Fig. 6, steel wire rope 4 pass second PVC plastic sleeve pipe 6 latter two head respectively with outrigger shaped steel Cantilever Beams 7 and outstanding
Builder's jack outer vertical rod 8, the connection of interior vertical rod 9 are fastened, finally with rope card（With steel wire rope units specification）10 tighten up, that is, complete oblique rollering steel
Cord 4 is worked by the drawing anchor of suspension ring and concrete structured beam 5.
During dismounting, suspension ring are first removed.Rope card 10 is loosened, steel wire rope 4 is extracted out, that is, completes the dismounting work of suspension ring.Tear open again
Except pressure ring.Nut 116 on screw rod 211 is turned on, pressing plate 12 is removed, recycles tower crane to hang out shaped steel Cantilever Beams 7, then with small
The top of hammer touch screw rod 211, you can remove adjustable base.After above-mentioned dismounting is finished, with microdilatancy pea gravel concreten by hole to be provided
Block.Due to the hole to be provided at suspension ring be it is low inside and high outside, therefore, the hole blocked will not seepage, thus thoroughly disappear
Except the hidden danger of exterior wall leakage.
The suspension ring of the present invention can be processed using the remaining iron plate leftover pieces in job site and bar dowel head.Without every time
The links such as blanking, processing are repeated before installing.The pressure ring and suspension ring installation operation of the present invention is convenient and swift, it is easy to dismantle, can be continuous
It is used in turn more than 50 times.Operating efficiency can be effectively improved, construction cost is both saved, is conducive to environmental protection again.
