Abstract
The invention discloses a hoisting construction technology of a steel bar cage, which comprises the steps that a main crane and an auxiliary crane move to hoisting positions; shackles of hoisting points on the main crane and the auxiliary crane are mounted prior to hoisting; mounting conditions and stress centers of steel wire ropes of the main crane and the auxiliary crane are checked; horizontal hoisting is performed; after the steel bar cage is hoisted to be 0.3m-0.5m from the ground, whether the steel bar cage is stable is checked, the main crane is hooked, and the auxiliary crane is matched with the main crane for hooking according to a distance between the tail of the steel bar cage and the ground; after the steel bar cage is hoisted, the main crane rotates to the left side or the right side and the auxiliary crane clockwise rotates to an appropriate position until the steel bar cage is perpendicular to the ground; a hoisting worker dismounts the shackle of the hoisting point of the auxiliary crane on the steel bar cage; the auxiliary crane is far away from a hoisting operation scope; and a cage of the main crane enters a groove and is positioned. When the steel bar cage is hoisted by the technology, a hoisting part of the steel bar cage is not required to be reinforced, and the steel bar cage does not deform in a hoisting process.
Description
Technical field
The present invention relates to a kind of reinforcing bar cage hoisting construction technology.
Background technology
Reinforced concrete bored pile is widely used in the building fields such as industry and civilian construction, railway and highway, in bored pile construction, reinforcing cage is transferred in boring is a very important link, because hoisting method is unreasonable, make the general insufficient rigidity of reinforcing cage, how easy appearance distortion, therefore, select a suitable reinforcing cage to hang method and just seem more crucial, lift and properly can ensure that reinforcing cage can not be out of shape, otherwise the distortion that reinforcing cage produces because of stressed when lifting can be aggravated.
Summary of the invention
For the above-mentioned technical problem existed in prior art, the present invention proposes a kind of reinforcing bar cage hoisting construction technology, reinforcing cage employing integral hoisting, entirety vertically once enter groove, and reinforcing cage there will not be distortion, and meets construction safety requirement.
To achieve these goals, the present invention adopts following technical scheme:
A kind of reinforcing bar cage hoisting construction technology, comprise main loop wheel machine and secondary loop wheel machine, it adopts following process step:
(1) main loop wheel machine and secondary loop wheel machine move to lifting position, install the shackle of Heave Here on main loop wheel machine and secondary loop wheel machine before lifting;
(2), after the wire rope installation situation checking main loop wheel machine and secondary loop wheel machine and stressed center of gravity, start flat hanging simultaneously;
(3) winch to overhead after 0.3m ~ 0.5m until reinforcing cage, check that whether reinforcing cage is steady, then main loop wheel machine hooks up, and secondary loop wheel machine coordinates main loop wheel machine to hook up according to reinforcing cage afterbody ground height;
(4) after reinforcing cage is sling, main loop wheel machine rotates to the left or to the right, and secondary loop wheel machine is clockwise to correct position, until reinforcing cage is perpendicular to ground;
(5) play the shackle of secondary loop wheel machine Heave Here on heavy industry removal reinforcing cage, secondary loop wheel machine is away from lifting operation scope;
(6) main loop wheel machine cage enters groove, location.
Further, 100t pedrail crane selected by described main loop wheel machine, and 50t crane selected by secondary loop wheel machine.
Further, in described step (2), the wire rope that main loop wheel machine adopts 3m long, the wire rope that secondary loop wheel machine adopts 18m long.
Further, in described step (1), Heave Here place full weld, main muscle and the horizontal bar of reinforcing cage adopt spot welding to be connected, and all adopt spot welding to connect within the scope of reinforcing cage surrounding and upper and lower 1 meter of position, Heave Here.
Further, in described step (1), lifting construction road is started route in lifting and is carried out hardened ground, below the place that ground is softer, lay 4cm steel plate, to ensure main loop wheel machine and secondary loop wheel machine walking path formation, the highness change of main loop wheel machine and secondary loop wheel machine is at 2cm ~ 3cm.
Advantage of the present invention is:
The present invention adopts integral hoisting, the overall construction method vertically, once entering groove according to designing requirement reinforcing cage, takes reliable and effective lifting construction scheme, meets safe construction requirement; When adopting the inventive method to lift by crane reinforcing cage, do not need to reinforce the lifting position of reinforcing cage, in hoisting process, reinforcing cage there will not be distortion.
Accompanying drawing explanation
Fig. 1 is that in the present invention, reinforcing cage adopts main loop wheel machine and secondary loop wheel machine to lift schematic diagram;
Fig. 2 is schematic diagram when main loop wheel machine cage enters groove in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
Shown in composition graphs 1, a kind of reinforcing bar cage hoisting construction technology, comprises main loop wheel machine 1 and secondary loop wheel machine 2, and 100t pedrail crane selected by main loop wheel machine 1, and 50t crane selected by secondary loop wheel machine 2, adopts following process step:
(1) main loop wheel machine 1 and secondary loop wheel machine 2 move to lifting position, the shackle of Heave Here 3 on main loop wheel machine 1 and secondary loop wheel machine 2 is installed before lifting, Heave Here 3 place full weld, main muscle and the horizontal bar of reinforcing cage 5 adopt spot welding to be connected, and all adopt spot welding to connect within the scope of reinforcing cage surrounding and upper and lower 1 meter of position, Heave Here 3; Lifting construction road is started route in lifting and is carried out hardened ground, below the place that ground is softer, lay 4cm steel plate, and smooth to ensure main loop wheel machine 1 and secondary loop wheel machine 2 road 4 of walking, the highness change of main loop wheel machine and secondary loop wheel machine is at 2cm ~ 3cm;
(2) after the wire rope installation situation checking main loop wheel machine 1 and secondary loop wheel machine 2 and stressed center of gravity, start flat hanging, the wire rope that main loop wheel machine 1 adopts 3m long, the wire rope that secondary loop wheel machine 2 adopts 18m long simultaneously;
(3) winch to overhead after 0.3m ~ 0.5m until reinforcing cage, check that whether reinforcing cage is steady, then main loop wheel machine hooks up, and secondary loop wheel machine coordinates main loop wheel machine to hook up according to reinforcing cage afterbody ground height;
