Description
Technical field
The utility model relates to the one I-steel security hardening structure of encorbelmenting.
Background technology
The security protection of construction scaffold is the important component part of building construction site safety protection, conventionallyThe console mode protective scaffolds that adopt are set up in the scaffold protection of multilayer or small sized multiple story building thing more; High-riseSegmentations encorbelment protective scaffold or the Integral lifting protective scaffolds of adopting more; Establish according to Project Construction Organization separatelyMeter or scheme require to tell somebody what one's real intentions are, set up, check and accept, use, supervision etc. The pin of encorbelmenting of its use on the middle and senior levelHand frame is substantially all to encorbelment and stretch out the base that is built into scaffold from beam slab edge with I-steel. For making to encorbelmentI-steel and beam slab have firmly syndeton, mainly contain at present following two kinds of ways:
1, U-shaped hot calendering circle HPB235 Φ 16 round steel of pre-buried clod wash are as the reinforcing built-in fitting of I-steel.Should be designed to steel wire rope or reinforcing pull rod and the off-load of last layer major structure of construction oblique pull at the end of overhanging type steel,And on oblique pull steel wire rope the pre-buried suspension ring bar diameter of stiff end should >=Φ 20mm, adopt equally the U of clod washType hot calendering circle HPB235 round steel. On construction site, most adopts steel wire rope to carry out oblique pull off-load,Diameter >=Φ 14mm of steel wire rope, specifically will pass through calculative determination. Common practice is now: generally in distanceThe shaped steel end of encorbelmenting is not less than one section of bar dowel of position welding or the short steel pipes of 100mm, and length is about 200mm,General diameter of phi 20mm-Φ 30mm.
2, adopt JGJ130-2011 " construction fastener type steel pipe scaffold technical specification of security " and inBuild the pre-buried two ends that require in joint-stock company 2014 editions " construction site safety protection standard atlas "Threaded U-shaped ring.
Above-mentioned construction method has the following disadvantages:
Use material is many, does not reach economical environment-protective green construction original intention, and the later stage removes with gas cutting Floor waterPlane is cut off with upper part, causes waste, can't have enough to meet the need that use, operating personnel's workload are large, when operationBetween long, construction operation personnel because of carelessness can also breaking out of fire risk, potential safety hazard is large.
Summary of the invention

Detailed description of the invention
Fig. 1 is the one I-steel security hardening structure of encorbelmenting. I-steel 1 is encorbelmented and is stretched out from beam slab 11 edges,The front portion cover of I-steel 1 has prelocalization hoop, and the rear portion of I-steel 1 is by positioning component after several and thisLayer beam slab connects, and the front end of I-steel is connected with beam slab 11 edges on upper strata by oblique pull steel wire rope 9.
Prelocalization hoop is the square frame-shaped stirrup 2 that adopts 5mm to form with upper steel plate bar or the butt welding of dimorphism channel-section steel,Square bar cuff, on I-steel, and is welded with spacer bar 4, square frame-shaped steel on the top of square frame-shaped stirrupThe bottom of hoop is provided with location jackscrew 3.
In Fig. 2, rear positioning component is made up of anchor plate 7, anchor bolt 5, upper laminated steel 6. 2Root anchor bolt 5 by the spacing of setting side by side and lower end and anchor plate 7 weld, the upper end of anchor bolt 5Constrain in 2 anchor bolts from bottom to top upper laminated steel 6 through floor and by the rear portion of I-steelBe connected with anchor bolt by nut and be pressed in I-steel end face fixing, and having in the outer surface cover of anchor bolt 5Pvc pipe 8. Upper laminated steel 6 is made for angle steel or steel plate. There is pvc pipe 6 in the outer surface cover of anchor bolt 5.
Oblique pull steel wire rope 9 one end are fixedly connected with I-steel front end, and the other end of oblique pull steel wire rope 9 passes through steelSilk rope fixation kit 10 is connected with upper strata beam slab 11 edges.
Steel wire rope fixation kit 10 is made up of sleeve and hook-shaped bolt. Sleeve is embedded in beam slab edge, upper strata,For ensureing that embedded sleeve barrel and beam slab are connected firmly, and are also welded with one section of reinforcing bar and are also together embedded in sleeve outerIn the xoncrete structure at beam slab edge, upper strata. In sleeve, be provided with internal thread, hook-shaped bolt top is hook-shaped and steelSilk rope end connects, and hook-shaped bolt bottom is straight shape bolt and is connected with internal thread of sleeve. Hook-shaped bolt bottomPre-buriedly front the part that is arranged in concrete is put to pvc pipe in advance, so that the later stage screws back-out.
JGJ130-2011 " construction fastener type steel pipe scaffold technical specification of security " and in build share public affairsTake charge of the fixing I-steel of encorbelmenting of describing in 2014 editions " construction site safety protection standard atlas " pre-Embedded part, there are the actual feelings such as location is inaccurate, waste material, complicated operation in the U-shaped ring of pre-buried TBE (threaded both ends)Condition, below by contrasting the superiority economically that can obviously find out the present embodiment:
Originally pre-buried I-steel fixture is calculated according to slab thickness 150mm. Single U-shaped reinforcing bar draw ringBuilt-in fitting is reliably fixing with major structure of construction beam slab, and pre-buried U-shaped reinforcing bar draw ring should be anchored to beam slab bottomReinforcing bar position, and firm with the welding of base plate bottom layer of the reinforcing steel or colligation, and anchorage length is with reference to GB50010 concreteRelevant regulations that structure specifies is carried out, and requires the Φ 16mmU steel bar draw ring should be at special reinforcement fabricationPlace cold roll forming, when installation, the gap between itself and shaped steel should adopt hard-wood wedge or gad wedging. ItsMinimum length is: L=(200+150+160) × 2+ (3.14 × 140 ÷ 2) ≈ 1250mm. Each work of encorbelmentingAccording to four calculating, (the I-shaped steel capital of encorbelmenting needs oblique pull steel wire rope to word steel, and the upper drawknot built-in fitting of steel wire rope is originalThe pre-buried Φ 20mm of common practices round steel, the suitable L=1250mm of length built-in fitting the shortest and fixing I-steel.Such I-steel just needs 4, i.e. 1250mm × 4=5000mm. Current index bed residential building or peaceThe construction area of putting 4 families, a general unit, room needs approximately 130 such I-steel. Approximately need round steel 130 ×5000=650000mm=6500m, according to tonnage meter: 1.58 × 6500=1020kg ≈ 10.2T. Market3300 yuan/ton × 10.2=33660 of market unit before marked price. At least choose by now large entry 30 multi tiered computingsCalculate approximately 33660 × 5=168300 unit 5 times. When recovery, must cut off L=160 × 2+3.14 × 140 ÷ 2=760Mm. Reclaim approximately altogether: 12488 yuan of m=760 × 4 × 130 × 1.58 × 2000 ≈. The saving of getting off like this becomesThis s=33660-12488=21172 unit. 5 layers is s=21172x5=105860 unit. (also do not comprise and cut off peopleThe machine-team of expenses of labour, gas expense, tower crane hoisting transportation takes etc.). An above Wei Yige building unit 4 family buildingThe consumption of area and calculation of price cost-saving. The scale that general current company accepts is at least above severalTen times of amounts, so cost savings are no small numerals.
Above-described the utility model embodiment, does not form the limit to the utility model protection domainFixed. Any amendment of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., allWithin should being included in claim protection domain of the present utility model.
