Description
Technical field
The utility model be related to bridge construction technical field and in particular to a kind of for bent cap bottom surface prestressed stretch-draw
Support arrangement.
Background technology
Increasingly focus on the harmony of bridge structure and surrounding environment with people, and also to be open to traffic under meeting bridge and
The requirement of broad view, great cantilever Prestressed Slab Beams become the preferred version of urban bridge design.
In order to improve the stress state of great cantilever Prestressed Slab Beams, bent cap beam body bottom surface is designed with prestressed stretch-draw
End, causes stretch-draw jack nowhere to hang it is difficult to carry out the difficulty of tensioning operation then.At present, this design is also less,
The existing device complex operation supporting stretch-draw jack, low construction efficiency, and be difficult to meet the placement of stretch-draw jack multi-angle
Require.
Content of the invention
The utility model provides one kind to be used for bent cap bottom surface prestressing force for solving technical problem present in known technology
The support meanss of tensioning, this device can form effective support to stretch-draw jack, and support angle is adjustable, strong applicability.
The utility model is adopted the technical scheme that by solving technical problem present in known technology：One kind is used for covering
The support meanss of soffit prestressed stretch-draw, including bracket, the flexible of hinge II and jack II is passed through in the front end of described bracket
End connects, and described jack II is obliquely installed, and the upper end of described jack II is forward compared with its lower end, and the rear end of described bracket is passed through
Hinge I is connected with moved cross beam, is provided with perpendicular jack I and two screw mandrels in the lower section of described moved cross beam, described
The telescopic end of jack I is connected with described moved cross beam, and described jack I is arranged on base I, and two described screw mandrels are respectively provided with
In the both sides of described jack I, the upper end of described screw mandrel is affixed with described moved cross beam, and described screw mandrel passes through described base I, and
Locked on described base I using nut；Described jack II is arranged on base II, and described base I and described base II are equal
It is arranged on support.
Described support is provided with chassis, and described chassis is provided with road wheel.
The utility model has the advantages and positive effects that：Structure is simple, easy to operate, can use manpower and material resources sparingly, peace
Entirely stable, efficiency of construction is high, effectively solves stretch-draw jack present in the prestressed stretch-draw process of bent cap beam body bottom surface
The technical barrier nowhere hanging.Compared with other support meanss, the utility model is cheap, by jack and hinge
Interact, meet the demand of different angle tensioning, strong applicability, there is good Social and economic benef@, build in bridge
If in there is promotion prospect.
