Description
Technical field
The present invention relates to a kind of scissor folded truss.
Background technology
During bridge maintenance, it is often necessary in bridge bottom hung steel structure platform, when platform span is more than 6m
Typically take field fabrication.This kind of platform structure is because of the big transhipment inconvenience of the scale of construction, it is impossible to reuses, high cost, wastes big.Bei Lei
Although this kind of fabricated construction convenient transportation of beam, this standard element can not compress the scale of construction, and cost of wheeling is high.If by work
Platform Designing is into the field-installed truss of single rod member, although cost of wheeling is low, but Assembling is time-consuming.
Chinese Patent Application No. discloses a kind of extended position beam element structure for 90222737.8, and the structure is by releasing
Some rod ends are hinged and set some telescoping rods, and truss is become to be folded again after geometrically unstable system.Due to needing people
Work releases some rod ends and is hinged, or manually rod end is connected on node, to high-altitude or job engineering performance difficulty high up in the air, therefore
It is necessary to design a kind of workbench, can draws in automatically, be easy to lift by crane and transhipment of packing, energy Automatic-expanding, is not required to when using
Manual work is wanted, is installed safely and fast.
Chinese Patent Application No. discloses a kind of folding plane girder in longitudinal direction for 201620008878.4 patent, should
Some member designs of truss are into telescopic component, using being hinged at rod node, it is not necessary to disassemble the rod member of truss, directly
The length of expansion link is controlled, realizes that the folding of girder system is drawn in or deployed.Because of the telescoping member unbalance stress of truss, when flexible
Bar not in scale synchronization telescope when, can make each internode of truss expansion or fold asynchronous, the profile thousand poor ten thousand that truss represents
Not, position of centre of gravity is difficult to predict, easily triggers lifting accident.
The content of the invention
In order to solve the above problems, the present invention proposes a kind of scissor folded truss, and the truss is stretched in scissor folding
Increase chord member and vertical web member on extending apparatus.The length of wherein vertical web member can with telescopic variation, chord member and vertical web member with tiltedly
The scissor fold mechanism of web member composition is hinged at node, by controlling the length of vertical web member, to realize that girder system is indulged
The function of drawing in or deploy to folding, and ensure that each internode deformation of truss is synchronous.
The technical proposal of the invention is realized in this way：
A kind of scissor folded truss, including diagonal web member, chord member and vertical web member, the diagonal web member chord pole length are all solid
Determine, and the medium position perforate of two diagonal web members is articulated and connected by scissor mode；The end perforate of two diagonal web members and hinge
It is connected to one end of a chord member in succession, the other end perforate of two chord members of opposite position and is hingedly connected to one another；It is described perpendicular
It is extension type to web member, and one end is hingedly fixed in the position that two chord members are hinged, the other end is hingedly fixed in two
The position that diagonal web member is hinged.
Preferably, including the above-mentioned truss that is continuously arranged side by side of at least two Pin, the diagonal web member between two adjacent truss structures
End be hinged.
Preferably, at least two groups above-mentioned truss are spaced and parallel is set, and top surface and the bottom surface of the system of every group of truss formation
Tiling horizontal panel forms workbench respectively.
Preferably, the vertical web member is made up of piston rod component, flexible by hydraulic control piston rod is controlled
Length processed.
Preferably, the component that the vertical web member is made up of screw rod, length is controlled by the rotation of motor control screw rod
Degree.
What the present invention was produced has the beneficial effect that：
(1) present invention is existed because the diagonal web member of truss is using scissor fold mechanism by the truss platform of the truss assembling
Fold or can realize that each internode deformation of truss is synchronous during deploying, truss platform controlled shape.
(2) after the expansion of conventional scissor folding device, under the effect of face internal loading, rod member internal force have moment of flexure, shearing and
Axle power, and the platform that the present invention is assembled forms the diagonal web member of a kind of parallel chord truss structure, wherein scissors apparatus after deployment
Main internal force is axle power, thus the high capacity of platform, and rigidity is big.
(3) the supporting workbench of C-shaped bridge maintenance unwheeling, when being lifted to workbench, Ke Yixian can be used as
The workbench of gathering is hung on the outside of bridge from bridge floor, platform expansion installation exercise is then carried out again.Due to being lifted by crane in bridge floor
Platform is in rounding state during platform, and sling height less, reduces the risk of workbench lifting.
(4) present invention can be used for assembling hoistable platform because can guarantee that the synchronously deformation of truss internode.

Embodiment, belongs to the scope of protection of the invention.
A kind of scissor folded truss, including diagonal web member 1, chord member 2 and vertical web member 3 as Figure 1-4, the diagonal web member
1 and the length of chord member 2 all fix, and the medium position perforate of two diagonal web members 1 is articulated and connected by scissor mode；Two
The end perforate of diagonal web member 1 and the one end for being hinge-connected to a chord member 2, the other end of two chord members 2 of opposite position are opened
Hole and it is hingedly connected to one another；The vertical web member 3 is extension type, and one end is hingedly fixed in what two chord members 2 were hinged
Position, the other end is hingedly fixed in the position that two diagonal web members 1 are hinged.
The present invention includes the diagonal web member between the above-mentioned truss that at least two Pin are continuously arranged side by side, two adjacent truss structures
2 end is hinged, and can increase the lateral length of whole truss.
Simultaneously when actually used, at least two groups above-mentioned truss are spaced and parallel to be set, and the system of every group of truss formation
Tile horizontal panel formation workbench respectively for top surface and bottom surface.The two above-mentioned truss of Pin identicals, parallel interval is certain after expansion
Distance erect and laid parallel, connect to form the constant three-dimensional system of geometry by rod member between two truss, keep every group of purlin
The height of frame is adjusted to equal, and the top surface of the system or bottom surface form longitudinal direction by the internode segmentation slab of two Pin plane girders
Foldable or expansion workbench or bridge.
Preferably, the vertical web member 3 is made up of piston rod component, flexible by hydraulic control piston rod is controlled
Length processed；The component that the vertical web member 3 can also be made up of screw rod, length is controlled by the rotation of motor control screw rod
Degree.
The present invention truss composition workbench, the length of the vertical web member 3 by changing truss, make workbench by
Longitudinal folding rounding state becomes the state of organizing work, or becomes longitudinal direction gathering folded state by the state of organizing work.Because of truss
Diagonal web member 2 use scissor fold mechanism, can realize that the deformation of each internode of truss is synchronous, prevent that truss from folding or expansion process
It is middle to occur surprisingly.The truss platform that this folding truss is badly in need of when can be as structural inspection and emergency repair, can also
When lifting platform is used.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modifications, equivalent substitutions and improvements made etc. should be included within the scope of the present invention.
