Description
Technical field
The present invention relates to science of bridge building field, transport particularly to a kind of feasible bridge guidance tape in plate-beam and car is installed.
Background technology
In bridges in highway engineering, due to easy to use, precoated plate has obtained widely as bridge guidance tape
Application.In prior art, bridge prefabrication method of plate installation has self-propelled gantry to manage to carry out to install in place, i.e.
Precoated plate is lifted into installation site by direct crane, and the method needs large-scale hoisting transportation equipment and construction field
, during lifting in the crane arm radius of clean-up and working height range, must not there be transmission line of electricity and other obstacle in ground,
Should not use under conditions of by space and plane size limitation, it addition, because of in view of generally there being water under bridge,
Hoist engine can be used to coordinate chain guides to manage, set up falsework at pontic two ends, longitudinally lay outside pontic
Two-way track, bridge one end hoist engine is fixed on end of the bridge, and other end hoist engine is separately fixed on each pier and can move
Dynamic, longitudinally moved beam by hoist engine, and take chain block to move beam with steel pipe transverse, precoated plate is installed successively,
The method operation complexity, needs to take a substantial amount of time and manpower and it needs to expend substantial amounts of fund, and lifting
During the security and stability in post not enough.Further, for ensureing that bridge entirety stress is put down when bridge prefabrication plate is installed
Weighing apparatus needs in the middle of bridge the symmetrical laying successively to two ends, and for this requirement, it is multiple that above-mentioned two methods all exist operation
Miscellaneous, the problem of inconvenience movement, and also above-mentioned two methods are required to spanning equipment outside pontic, substantially increase
Set up cost.
Therefore, for laying bridge guidance tape on built steel truss, one is needed at girder truss and to lay bridge road
The most transitable transport installation equipment on plate, has and is easy to move, convenient use, and the feature of simple in construction can
Bearing bridge guidance tape is walked on bridge truss and the bridge guidance tape that lays, and can be convenient and swift safe to bridge road
Plate is installed, and greatly reduces the consuming of manpower, time and fund.
Summary of the invention
In view of this, the present invention provides a kind of feasible bridge guidance tape in plate-beam to transport and installs car, has and is easy to move
Dynamic, convenient use, the feature of simple in construction, can bearing bridge guidance tape on bridge truss and the bridge guidance tape that lays
Walking, and can convenient and swift safe bridge guidance tape is installed, greatly reduce manpower, time and fund
Expend.
