Description
Technical field
The present invention relates to the reinforcing bar cage hoisting technical field of construction in pattern foundation pit supporting structure or hazard management engineering, the foundation work.
Background technology
In pattern foundation pit supporting structure, hazard management engineering or the construction of foundation work, for super large, super long type steel reinforcement cage (refer generally to length and surpass 30m, weight surpasses 5 tons steel reinforcement cage), the construction method of traditional merogenesis lifting can't satisfy construction requirement.Because when practical operation; The operating surface that does not have many cranes when 1, no merogenesis lifts; 2, merogenesis lifting is consuming time for a long time, has become hole because putting into steel reinforcement cage and casting concrete does not for a long time cause the hole of collapsing easily, and 3, whether the joint area of merogenesis steel reinforcement cage firmly bigger to the quality influence of steel reinforcement cage.
Summary of the invention
The objective of the invention is: a kind of ultra-large type steel reinforcement cage overall time hanging method is provided; Solved the ultra-large type steel reinforcement cage at amerism; Do not change the technical matters that the situation of structure lifts next time, and working security high, workable, satisfy construction period, improve operating efficiency.
The technical scheme that the present invention adopts is:
A kind of ultra-large type steel reinforcement cage overall time hanging method mainly comprises the steps:
1) colligation of steel reinforcement cage: steel reinforcement cage is that length surpasses 30m, and weight surpasses 5 tons ultra-large type steel reinforcement cage, and the disposable colligation of whole steel reinforcement cage is finished; Steel reinforcement cage adopts straight thread to connect technology, in the steel reinforcement cage process of binding, and the main muscle mechanical connecting joint 40d that staggers each other; And satisfy code requirement, and whenever the hoop of putting more energy into together being set at a distance from 1500mm, put more energy into and bind round the one-level steel work that the employing diameter is 20mm in first road, steel reinforcement cage top; And establish interior gusseted, the interior gusseted and the hoop welding of putting more energy into;
2) configuration of suspension centre layout and crane: first crane (1) reaches near the afterbody end and is positioned at 1/4 section of total length at the steel reinforcement cage afterbody locates to select two suspension centres; Second crane (2) locates to select two suspension centres 1/3 section and 2/3 section of steel reinforcement cage total length; Four suspension centres of the 3rd crane (3) all are chosen in the top of steel reinforcement cage, and four suspension centres of the 3rd crane (3) at grade and rectangular distribution;
Wherein first crane (1) and second crane (2) are whipline, are respectively 25T, 70T wheel crane; The 3rd crane (3) is main crane, is the 90T wheel crane;
3) main suspension hook is connected with selected suspension centre, accomplish the level lifting of steel reinforcement cage: three crane master suspension hooks rise simultaneously, and the steel reinforcement cage level is hung ground;
4) steel reinforcement cage is changed to plumbness by horizontality: when steel reinforcement cage satisfied the setting height, the main suspension hook of first crane stopped to hoist, and the main suspension hook of second crane and the 3rd crane continues to rise simultaneously; The main suspension hook of the 3rd crane continues to hoist then; The main suspension hook of first and second crane descends gradually, and the purpose of three crane master suspension hook adjustment up-downs is to guarantee the steel reinforcement cage in-line all the time in the whole process, and the suspension hook of three cranes is simultaneously stressed; Stand vertically up to steel reinforcement cage; In case occur three crane master suspension hooks rise or descend inharmonious, crane commander adjustment in time, the 3rd crane has stopped the hook action and the inspection steel reinforcement cage is out of shape situation;
5) utilize the 3rd crane with the direct hoisted in position of the steel reinforcement cage that stands vertically.
The connection mode of the main suspension hook of first crane and second crane and suspension centre is in the said method: adopt the hoist cable that length is 15m; Be locked in two statures of hoist cable branch on two suspension centre suspension ring that welded with D type snap ring; The center of steel rope is hung on the main suspension hook of crane, guarantee that steel reinforcement cage setting process crane main hook suspension centre can increase and change along with steel reinforcement cage bottom weight;
The connection mode of the main suspension hook of the 3rd crane and suspension centre is in the said method: adopting four length is the 1.5m hoist cable; Adopt D type snap ring to be connected with four the suspension centre suspension ring in steel reinforcement cage top respectively four statures of hoist cable, with hoist cable four statures in addition hang on the main suspension hook of the 3rd crane.
The invention has the beneficial effects as follows: through the rigidity of suitable increase steel reinforcement cage, the setting hoop of putting more energy into to steel reinforcement cage, gusseted etc. have guaranteed the Deformation control of steel reinforcement cage in the lifting process; Reasonable arrangement through each crane Heave Here; Through the control method of sight alignment, controlled the distortion of steel reinforcement cage in hoisting process more accurately, guaranteed the lifting effect; Connection mode between hoist cable and suspension centre and the main suspension hook; Guaranteed that steel reinforcement cage main suspension hook in the setting process realizes self-control along with the variation of position, all stressed and guarantee steel reinforcement cage in-line, the selection of different crane tonnages all the time to be implemented in the whole process of vertical lifting three crane master suspension hooks; Also take into account lifting demand and actual building cost, promoted lifting efficient; Through 3 lifting appliances ultra-large type steel reinforcement cage of slinging jointly; And from level to vertical angular transition, the ingenious conversion of carrying out suspension centre has realized that the ultra-large type steel reinforcement cage is at amerism; Do not change the situation property lifting next time of structure; Improved the efficient of lifting operation, and can casting concrete, realized working security, operability, satisfied construction period, raised the efficiency.
