Embodiment
Below by taking the aerial vestibule of Nanjing ancient cooking vessel positive purchase of property No.2011G38 plot project as an example, the project underground height
13.75m, ground height 63.8m, total height 77.55m.Vestibule truss depth 2.3m, span 39m, assembled absolute altitude -6.1m are promoted
Height about 71m.It is 750,000 or so according to prior art estimated charges.Total cost is 340,000 yuan of left side after using the method for this example
Construction cost 55% or so is saved on the right side.
The method of this example is that vestibule truss is divided into three sections, including a middle truss and two end truss 6, two end truss
6 as promoted platform base rack can directly in construction ceiling 1 it is assembled in place.When assembled end truss 6, the branch of truss 6 is held
15 bottom of foot should pad shock isolating pedestal 5；Shock isolating pedestal 5 uses friction pendulum shock isolating pedestal, and shock isolating pedestal 5 includes lower seat 20 and upper
Seat 21, lower 20 top surface center of seat are equipped with frustum 22, and 22 top surface of frustum and 21 bottom surface of the seat of honour are concave spherical surface 23；Upper and lower two recessed balls
Isolation cushion 24 is equipped between face 23.Lifting process can be made more stable by isolation cushion 24.Shock isolating pedestal 5 is to be located at support conjunction
In 17, support closes 17 and welds with supporting steel plate 2；Support closes and is welded with stiffening plate 18 between 17 outer rims and supporting steel plate 2, with
Increase the intensity that support closes 17.There are gaps between 5 surrounding of shock isolating pedestal and support 17 interior frames of conjunction, in lifting process, are
Ensure to hold the stability of truss 6, gap is by one group of snap-gauge 19 by shock isolating pedestal 5 jam-packed.
After holding the assembled position of truss 6, truss 6 will be held by earth anchor rod 7 and be embedded on construction ceiling reinforced concrete knoll 3
Earth anchor steel plate 4 connect, opposite end truss 6 reinforced.Then it is set in the auxiliary that the top installation of 6 liang of the truss surveys in end promotes platform
It applies.Auxiliary equipment includes pillar 8, horizontal overarm 11, support rod 13, bearing diagonal 14 and leading truck 26.The effect of pillar 8 is will to mention
Peaceful raising certain altitude can dock after being promoted in place in order to middle truss with end truss 6.The lower end and end purlin of pillar 8
It welds 9 upper end of column of 6 front end two sides of frame.The upper end of pillar 8 and the welding of 11 one end of horizontal overarm.Level overarm 11 effect be
It is corresponding with the hoisting point position on middle truss that hoist point is forward extended out into certain distance.The horizontal overarm in lifting process in order to prevent
11 is sagging, is equipped with support rod 13,13 one end of support rod and horizontal overarm 11 front bottom ends weldering in 11 overhanging one end of level overarm
It connects, 9 lower end of column of 13 other end of support rod and end truss 6 is welded.The horizontal overarm 11 or so in lifting process in order to prevent
It swings, is welded with bearing diagonal 14,14 one end of bearing diagonal and horizontal overarm 11 leading insides weldering in 11 overhanging one end of level overarm
It connects, is welded in the middle part of the crossbeam of 14 other end of bearing diagonal and end 6 front bottom end of truss.11 overhanging one end of level overarm are equipped with notch
12, lift cylinder 25 is installed on notch 12.Cable wire 27 influences to promote operation in lifting process in order to prevent, in lift cylinder 25
Rear side is to be welded with leading truck 26, can be led too long cable wire 27 by leading truck 26 in the side for not influencing promotion operation.
After the device of the utility model promotes middle truss in place, need to dock middle truss with end truss 6.It is taken out when docking
The snap-gauge 19 being stuck in 17 interior frame gaps of shock isolating pedestal 5 and support conjunction, makes that truss 6 is held to have certain horizontal freedom degree, with
Convenient accurate docking.The effect of the concave spherical surface 23 of 21 bottom surface of 22 top surface of frustum and the seat of honour makes that truss 6 is held to have centainly when being contraposition
Angular freedom, to facilitate accurate docking.Middle truss can also be made to have certain extendable room when expanding with heat and contract with cold simultaneously.
The utility model is using the end truss at skybridge truss both ends as the foundation structure for promoting platform, stability
It is good, convenient for docking after promotion.It does not need to remove assembled end truss after docking, it is only necessary to remove some additional structures.
It sets up and removes and is very convenient.Since the utility model is using the end truss at skybridge truss both ends as the basis for promoting platform
After structure, skybridge truss middle section can be after ground be completed, by promoting platform for vestibule truss middle part
Divide whole promotion, construction operation is concentrated mainly on ground, can be down to amount of high-altitude operation at least, to the construction infection of other professions
It is smaller, and can more than enough work surface parallel construction.In addition the end truss at vestibule truss both ends is eliminated, only needs to mention in lifting process
Skybridge truss middle section is risen, promotion total weight is reduced, promotion difficulty is reduced and is conducive to construct.It is put down removing to be promoted
When platform, it is only necessary to remove the increased temporary facility on the truss of end, retain the end truss set up, reduce dismounting work
Amount, is conducive to construction cost control.
