Description
Technical field
The utility model relates to the construction equipment on bridge engineering basis waterborne, is meant a kind of super large shaped steel box horizon adjustable positioner especially.
Background technology
Along with continuing to bring out of China's deep water large-scale bridge, the foundation structure form of deep water large-scale group pile cap is frequently adopted.The deep water cushion cap generally adopts the enclose water-bound of steel box as its construction at present.Because steel box structure is huge, when especially hydrologic condition is complicated, bring certain difficulty for the location construction of box.Horizontal location in the past adopts fixing stopping means traditionally, need continue to add the cushion block positioning after box is transferred and put in place, and this kind method difficulty of construction is bigger, complex operation, and the flexibility of positioning shortage, and positioning accuracy is poor.For this reason, engineers and technicians also constantly explore various steel box localization method, as application number is the targeting scheme that 03128219.9 patent of invention has just proposed the whole transportation by driving anchor pier of a kind of steel box pre-exerting tension, and this scheme takes firm twisted wire prestress system to carry out the horizontal location of steel box.But because just twisted wire is an elastomeric material, control its stretching with the stretch-draw jack, bracing force weakness in the system, its accurately adjust and fixed effect still not ideal enough.
Summary of the invention
In order to solve accurate adjustment difficulty and the relatively poor deficiency of fixed effect that exists in the construction of present steel box horizontal location, it is a kind of accurately easy to adjust that the utility model provides, and fixed effect super large shaped steel box horizon adjustable positioner preferably.
The technical scheme that the utility model adopted is: design a kind of super large shaped steel box horizon adjustable positioner, it is characterized in that: the built-in sleeve 7 that is provided with on steel box wallboard 1, be plugged with flexible push rod 3 in the sleeve 7, flexible push rod 3 links to each other with steel casing wallboard 9 by arc jacking 8; Sleeve 7 one sides have jack 2, and opposite side is connected with sleeve stiffening rib 6; One end of jack 2 connects steel box wallboard 1, other end apical grafting reaction plate 4, and reaction plate 4 vertically is connected with reaction plate stiffening rib 5, and is fixed on flexible push rod 3 ends and the arc jacking 8; It is a pair of that every group of mechanism unit horizontal parallel is provided with sleeve 7, between two sleeves 7 lateral ties rod member 10 arranged.
The operating principle of the utility model horizontal positioning device is to utilize near the box wallboard steel casing as the counter-force bearing object, utilizes jack to regulate the stroke of flexible push rod during the location, and it is accurately in place by the horizontal reacting force of steel casing the steel box to be able to.Before box is transferred, each is organized the box wallboard inboard that horizontal positioning device layering is evenly arranged in all directions, after box is transferred to design elevation, beginning level positioning construction.During operation, measure the horizontal off normal situation of box, and utilize jack to regulate repeatedly, reach design attitude up to the steel box.
The beneficial effects of the utility model are, have improved the reliability and the convenience of box horizontal location, make box horizontal location operating flexibility convenient, have improved the efficiency of construction of location, have guaranteed the positioning accuracy of box conscientiously.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of every group of mechanism unit of horizontal positioning device.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is that the integral planar of the utility model horizontal positioning device is arranged schematic diagram.
Among the figure: 1, steel box wallboard; 2, jack; 3, flexible push rod; 4, reaction plate; 5, reaction plate stiffening rib; 6, sleeve stiffening rib; 7, sleeve; 8, arc jacking; 9, steel casing wallboard; 10, lateral ties rod member.
The specific embodiment
As depicted in figs. 1 and 2, every group of mechanism unit of this horizontal positioning device includes steel box wallboard 1, jack 2, flexible push rod 3, reaction plate 4, reaction plate stiffening rib 5, sleeve stiffening rib 6 (Fig. 2 can clearly show), sleeve 7, arc jacking 8, steel casing wallboard 9, lateral ties rod member 10; Signal is as can be seen from figure: the built-in sleeve 7 that is provided with on steel box wallboard 1, be plugged with flexible push rod 3 in the sleeve 7, and flexible push rod 3 links to each other with steel casing wallboard 9 by arc jacking 8; The parallel jack 2 that is equipped with of sleeve 7 one sides, opposite side is welded with sleeve stiffening rib 6; One end of jack 2 connects steel box wallboard 1, other end apical grafting reaction plate 4, and reaction plate 4 vertical weldings are connected to reaction plate stiffening rib 5, and are fixed on flexible push rod 3 ends and the arc jacking 8; It is a pair of that every group of mechanism unit horizontal parallel is provided with sleeve 7, is provided with lateral ties rod member 10 between two sleeves 7.
Fig. 3 is that the integral planar of horizontal positioning device is arranged schematic diagram, therefrom as can be seen, this the device by some groups independently mechanism unit form, utilize near the box wallboard 1 steel casing wallboard 9 as the counter-force bearing object, utilize jack 2 to regulate the stroke of flexible push rod 3 during the location, it is accurately in place by the horizontal reacting force of steel casing wallboard 9 the steel box to be able to.Before box is transferred, each is organized steel box wallboard 1 inboard that horizontal positioning device layering is evenly arranged in all directions, after box is transferred to design elevation, beginning level positioning construction.During operation, measure the horizontal off normal situation of box, and utilize jack 2 to regulate repeatedly, reach design attitude up to the steel box.
The utility model super large shaped steel box horizon adjustable positioner has improved the reliability and the convenience of box horizontal location, makes box horizontal location operating flexibility convenient, has improved the efficiency of construction of location, has guaranteed the positioning accuracy of box conscientiously.
