Be labeled as among the figure: cross bar 1, vertical rod 2, wall-connecting piece 3, scaffold floor 4, section steel beam 6, wire rope 7, spacer bars 8, hanger 9, baffle plate 10, anchor ring 11, ring through walls 12, scissors strut 13, sealing underframe 14.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1~shown in Figure 4, tools type section steel fastener steel tube outer scaffold of the present utility model, set up the formation external scaffolding by combinations such as cross bar 1, vertical rod 2, fastener, wall-connecting piece 3 and scaffold floors 4, external scaffolding is connected it by wall-connecting piece 3 with the agent structure of building, scaffold building height≤24m is safe and reliable to guarantee.The external scaffolding positioning supports can be produced corresponding location structure on section steel beam 6 on section steel beam 6, its external scaffolding can not moved on section steel beam 6.One end of section steel beam 6 is fixed on the structure of building, and the other end of section steel beam 6 is by wire rope 7 upward drawing on the structure that is fixedly connected on building.Because section steel beam 6 is the main support parts, so section steel beam 6 preferably adopts i iron to make.Cross bar 1 and vertical rod 2 can be adopted the steel pipe of φ 48 * 3.5mm, thereby form the double external scaffolding of fastener type steel pipe.Cross bar 1 is divided into long cross bar 1 and short cross bar 1 usually, and long cross bar 1 is roughly parallel to the setting of building external surface, and short cross bar 1 is approximately perpendicular to the setting of building external surface.The setting that this external scaffolding can adopt the vertical rod 2 in vertical rod advance 1.8m, vertical rod transfer 1.0m, scaffold step pitch 1.8m, the outside to build 350mm apart from section steel beam outer end 50mm, inboard vertical rod 2 distances, increase by one flak jacket railing in the middle of 2 per steps of vertical rod in the outside, vertical rod 2 inboards in the outside completely hang the green close order safety net of 2000 orders.The length of section steel beam 6 determines by designing requirement, outer beam segment length 1400mm, 2000mm of building wherein, and installation length should meet design requirement in the building.
For satisfy the external scaffolding positioning supports on the requirement on the section steel beam 6, the structure of convenience type girder steel 6 at building installing and locating and convenient on section steel beam 6 fixing wire rope 7, section steel beam 6 is provided with spacer bars 8, hanger 9 and baffle plate 10.Baffle plate 10 leans against on the wall face of building, section steel beam 6 is by baffle plate 10 and be embedded in anchor ring 11 stationary positioned on the structure of building, vertical rod 2 covers of external scaffolding are through on the spacer bars 8, one end of wire rope 7 is fixed on the hanger 9, the other end of wire rope 7 is fixed on the ring 12 through walls, and ring 12 through walls is fixed on the structure of building.
Initial when setting up floor concreting, design outside the building around the wall pre-buried anchor ring 11 built-in fittings such as grade, hole to be provided on the structure by the scaffold layout, anchor ring 11 can adopt reinforcement fabrication.The effect of anchor ring 11 is exactly the erection support end of fixed girder steel 6, and after section steel beam 6 passed in the ring of anchor ring 11, hard-wood wedge ecto-entad jam-pack can be used in its gap.During installation, should make the section steel beam outer end than inner (being the erection support end) high certain distance, constantly set up rising at external scaffolding, after load continues to increase, when wire rope 7 is tightened up gradually, can produce a spot of displacement deformation, but the decline displacement that distance balance rope 7 distortion that the outer end is enhanced during so initial mount type girder steel 6 are produced, make section steel beam 6 be adjusted to level, when setting up design height with assurance external scaffolding system, connection system for guide rail can not form the flare phenomenon.
When section steel beam 6 is installed, because upper floor does not also form, the work of the wire rope 7 that tiltedly draws can't be finished, so the outer end of section steel beam 6 can only utilize the external scaffolding of lower floor to set up the interim support fixation of elongated horizon bar, section steel beam 6 strong points should be tried one's best near vertical rod 2 places of lower floor's external scaffolding.The interim support of elongated horizon bar should treat that the wire rope 7 that tiltedly draws installs the back and removes.
When external scaffolding was set up, double that sets up 3 vertical rods 2 earlier formed the parent frame, and this parent frame is set up the bar of sweeping the floor together, two step horizon bars, and the place of keeping at a certain distance away sets up the scissors strut 13 of level to guarantee the stability of parent frame on the end face of section steel beam 6.Extend the whole external scaffolding system that sets up from parent frame two ends to both sides then.These all should set up, repeat no more here in strict accordance with " building operations button steel pipe scaffold technical specification of security " JGJ130.
In order to reach best stressed effect, section steel beam 6 preferably is in the same perpendicular with the axial line of wire rope 7.
In order to alleviate the stressed of cross bar 1 and vertical rod 2, can adopt the mode of drawing unloading on the wire rope 7 that adds, i.e. many wire rope 7 continuous upward drawing on the structure that is fixedly connected on building at stressed weakness in position such as the corner of building, balconies.
Integrally-built stable in order to strengthen, be provided with vertical scissors strut 13 in opening part, two ends and the horizontal linear distance of scaffold less than the 15m place, scissors strut 13 is fixed in the vertical rod 2.Vertical scissors strut 13 cross over 6 vertical rods 2 and with horizontal plane at 45~60 ° of angles set up continuously.
Same reason, integrally-built stable in order to strengthen, the end face of section steel beam 6 is provided with the scissors strut 13 and the sealing underframe 14 of level, also sets up continuously in the vertical rod 2 of both sides inside and outside the two ends of the scissors strut 13 of level are connected to.Scissors strut 13 is fixed on the short cross bar 1, with the monolithic stability of reinforcement support body and the job safety of operation layer, prevents that work layer from having people or thing to fall.In section steel beam 6 superolateral vertical rods 2 and sweep the floor and between bar and first long cross bar 1 vertical scissors strut 13 can be set also.
In order to strengthen overall construction intensity, wall-connecting piece 3 can be striden setting by two steps three, and the cross bar 1 in promptly every interval, three vertical rods 2 in interval are provided with a wall-connecting piece 3.
Scaffold floor 4 can all be provided with in per step, but for economical with materials, at operation layer scaffold floor 4 is set usually.
Whole external scaffolding system (JGJ130-2001) requires to set up in strict accordance with " building operations fastener type steel pipe scaffold technical specification of security ", and close order safety net, safe plain net, lightning protection etc. are set.Shelf is set up and is finished, and carries out closure construction with qualified close order safety net, and satisfactory blanket net is set, and work layer is divided into layer net.
