Description
Technical field
The invention belongs to bridge construction technical fields, and more specifically, in particular to a kind of bridge construction is temporarily taken
Build portable folding footbridge structure.
Background technique
With the aging of bridge, the bridge quality that early stage is built is further unstable, needs to be removed row again in time and builds,
Support personnel walks safe；But bridge is complex, can not build in the short time, in the period of building, is easy to week
The trip of the family Bian Ju causes obstacle, needs to build the bridge for personnel's walking in bridging toughening period, ensures that periphery occupies family and goes out
Row.
Based on above-mentioned, the inventors discovered that, existing footbridge structure, such as number of patent application CN205591098U are mentioned
The detachable bridge on foot of a kind of portable Fast Installation arrived, including two be embedded in vertically on the ground of river two sides respectively
Pylon, two pairs of combination anchorage stakes and folding bridge floor, two pylons are set side by side and are parallel to each other, and each pylon deviates from the one of river
A pair of corresponding combination anchorage stake is buried on the ground of side, is equipped with two main push-towing ropes being parallel to each other between two pylons, often
The both ends of main push-towing rope are separately connected the top of corresponding two pylons, fold bridge floor and are horizontally set between two pylons, and position
In the lower section of two main push-towing ropes, and its both ends passes through anchoring pile and is fixed on the ground of river two sides, folds bridge floor relative to its length
The two sides in direction pass through a corresponding main push-towing rope of several hoist cable connections top respectively, and each pair of combination anchorage stake passes through pair respectively
Cable connects corresponding tower top.Advantage: it is simple in construction, easy to disassemble and assemble, more quick, light weight is set up, it is easy to carry,
Practicability is stronger.
A kind of vertical collapsible pontoon bridge of spanning that also such as number of patent application CN106284051B is previously mentioned, belongs to pontoon bridge skill
Art field, the pontoon bridge include more than two modularization pontoon bridge units, even bank springboard, anchoring system and electric control system；Mould
Block pontoon bridge sequence of unit is fixedly connected, and passes through locking device between the modularization pontoon bridge unit in flow width middle position
It is fixed；Fixed module pontoon bridge unit forms pontoon bridge main body across river, the modularization pontoon bridge list on bank after being fully deployed
Member overlap joint even forms complete pontoon bridge after bank springboard, pontoon bridge main body since the modularization pontoon bridge unit of installation locking device successively
Close up, it is current for ship that navigation channel can be opened after the completion of closing up；Each modularization pontoon bridge unit is correspondingly connected with a set of anchoring system；
Electric control system control module pontoon bridge unit close up and expansion movement and action sequence.The present invention can be rapidly by floating
Bridge center is collapsed to the folding of two sides direction, open navigation channel, and pontoon bridge can rapid deployment recovery original sample after ship is current.
Based on the retrieval of patent at above-mentioned two, and device in the prior art is combined to find, although above-mentioned apparatus can
Meet personnel go on a journey needs, but its during actual use there are some problems, include: installing and dismounting is more numerous
It is trivial, it is easy the consumption plenty of time, bridge could be built and be finished, in the build process of long period, is easy to periphery user
Trip impact；And device specification is larger, can not fold up well in disassembly, is easy to occupy more storage
Difficulty is caused to the transport and storage in later period in space.
Then, in view of this, being studied improvement for existing structure and missing, a kind of facing for bridge construction is provided
When build portable folding footbridge structure, to achieve the purpose that with more more practical value.
Summary of the invention
Portable folding walking is temporarily built in order to solve the above technical problem, the present invention provides a kind of bridge construction
Bridge structure, to solve existing footbridge structure, installing and dismounting is relatively complicated, is easy the consumption plenty of time, could take bridge
It builds and finishes, in the build process of long period, be easy to impact the trip of periphery user；And device specification is larger,
It can not be folded up well in disassembly, be easy to occupy more parking space, difficulty is caused to the transport and storage in later period
The problem of.
The purpose and effect for temporarily building portable folding footbridge structure of bridge construction of the present invention, by detail below
Technological means is reached:
A kind of bridge construction temporarily builds portable folding footbridge structure, including folding support frame, connecting rod, bridge plate
