Description
Technical field
The present invention relates to a kind of method of climbing of high-rise building Inner climbing tower machine.
Background technology
Inner climbing tower machine is when the high-rise building of construction height more than 100m, usually two-layer support steel beam has only been installed and Inner climbs frame, when Inner climbing tower machine climbs, installation the 3rd road Inner is needed to climb support steel beam and Inner climbs frame, namely need one, the bottom support steel beam of movement when last time, Inner climbed to be moved to topmost, climb frame with fixing Inner; Afterwards hydraulic jacking device is installed; The trim of tower machine; The jacking of tower machine; Complete and climb.The movement of girder steel has following several mode: (1), the Inner climbing tower auger mouth reserved by building, tower machine is utilized to move, this kind of mode is minimum because tower machine exists hangs width, require that reserved opening is larger, and the structural limitations of often building, the requirement of reserved opening out of reach, thus cause abuse pull and hang sideling, even cannot move; (2), on building floor, first girder steel is moved horizontally to building outer rim, recycling tower machine is lifted to building top, be installed to the desired location of the 3rd road girder steel by the reserved opening of Inner climbing tower machine, this kind method operating sequence is more, the time is longer, floor passage that girder steel passes through need be cleared up, require that reserved opening is larger simultaneously.
At present, because of the reason of project construction technique, cannot reserve enough large space to Inner climbing tower machine, support steel beam directly adopts steel corbel to be fixed on shear wall, and the construction of floor plates lags far behind the construction of shear wall.When tower machine Inner climbs operation, cannot set up scaffold, operating personal is without operation planar space, and the vertical of support steel beam moves without passage, and meanwhile, parallel motion, also without service platform, like this, cannot use tower machine handling support steel beam.When Inner climbing tower machine climbs, also need scaffolding, so that the operation of personnel, because support steel beam adopts steel corbel to be fixed on shear wall, whole connection all adopts the type of attachment of welding, so person works's amount when removing and install is very large, because of the reason of project construction technique, enough large space cannot be reserved to Inner climbing tower machine, so scaffold cannot be set up in scene.
Summary of the invention
The object of the invention is to overcome above deficiency, a kind of method of climbing of easy to operate, high-rise building Inner climbing tower machine that efficiency is high, safe and reliable is provided.
Object of the present invention is achieved through the following technical solutions: a kind of method of climbing of high-rise building Inner climbing tower machine, comprises the following steps:
A, the 3rd road Inner is installed climbs support steel beam and Inner climbs frame: on tower machine tower body, an interim hoisting mechanism is installed, vertical handling support steel beam in limited space, Hanging Basket is fixed in Inner climbing tower machine topside, operating personal is had a stable service platform;
B, hydraulic jacking device is installed: the Inner on second support steel beam climbs and Inner installed by frame climbs hydraulic jacking device;
C, the trim of tower machine, be divided into movable arm type tower machine and the trim of hammerhead tower machine, be specially:
The trim mode of movable arm type tower machine: adjustment center-of-gravity position, makes climbing support drop on the position of jacking cylinder with the center of gravity on top, the method for balance-seeking, can realize by regulating the tilt angle of crane arm, this angle can regulate within the scope of 50 ~ 55 degree.Concrete adjustment can carry out according to actual conditions the center-of-gravity position regulating crane arm.Then unclamp the tie bolt of undersetting and tower body, a little jack-up climbing support, the four rolling observed on climbing support does not contact with tower-body standard section substantially, observes tower body joint chord member locating dowel pin simultaneously and does not depart from undersetting pin-and-hole, be ideal position;
The trim mode of hammerhead tower machine: hang a joint standard knot with loading trolley and run to trim reference position in tower machine service instructions, then remove the connection bearing pin of undersetting four legs and standard knot.Hydraulic jacking system joystick is pushed into jacking direction, makes climbing support jacking just depart from the position of the main chord of tower body to undersetting leg.Whether the inspection leg that is connected with standard knot of undersetting and tower body main chord be on a perpendicular line, and whether observe 16 track adjusting wheels on climbing support substantially identical with tower body main chord gap, to check whether tower machine balances, as overbalance, then adjust the trim position of loading trolley, until balance, tower machine upper center of gravity is dropped on the position of jacking cross beam.
D, the jacking of tower machine: 1), by jacking cross beam withstand on hithermost tower body and to mark time lower prong, control hydraulic system, by tower body jack-up 1.4-1.8m, then interior climbing on framework in four is climbed strut and be supported on tower body marks time, in case the degeneration of tower machine, then regain oil cylinder, on jacking cross beam support is marked time at lower a pair, handle oil cylinder upwards jacking 1.4-1.8m, and then prop up another to marking time with strut, go round and begin again like this;
2), when climbing plane on framework in interior four semi-girders of climbing base section exceed, pulling out four semi-girders and then regaining piston rod, climbing on framework in four semi-girders allowing tower crane save are located in;
3), interior lifting body of climbing is removed and installed in last layer and climbs on frame, and the push rod of climbing in mounting and adjusting on framework is in middle frame place, push rod is contacted with tower body chord member, adjustment tower body center requires within 0.0015 horizontal plane degree, climb frame plane by mounting stay in tower body and hold out against going up most in one, then adjust each 8 jacking blocks of lower work framework, tower body is held out against.
4), as continued climb, repeat said process.
E, complete and climb.
The present invention compared with prior art has the following advantages: on tower machine tower body, install an interim hoisting mechanism, without the need to larger Inner climbing tower auger mouth reserved in building, can in limited space vertical handling girder steel; Hanging Basket is fixed in Inner climbing tower machine topside, operating personal is had a stable service platform, without the need to scaffolding.Whole technological process is by original three days time decreased by one day, and efficiency of climbing improves, and meanwhile, the safety of operating personal also obtains failure-free and ensures.
