Description
Technical field
The invention belongs to field of road construction more particularly to a kind of overhead bridge construction telescopic device methods.
Background technique
Expansion joint, that is, expansion joint is built, refers to prevent building member since climate temperature changes (heat expansion, shrinkage), makes
Structure generates crack or destruction and along a build joint of the suitable position in building or structures construction joint direction setting.Make
Building or structures can do horizontal extension along length direction.Along building length direction reserving gaps at a certain distance, will build
It is all off to build object ground member, building basis because its be embedded in underground influenced by temperature change it is small, it is not necessary to disconnect.Reasonable selection
The gap of appropriate stroke is particularly important, and the bigger telescopic device in gap is easier to go to pot.The gap of use is excessive or too small, with
And it does not account for temperature when installing and adjusts gap.Especially for board-like Telescopic rubber device, destruction is easily caused.Even
Continuous deck will also tend to cracked on surface layer is mated formation.Therefore.Take in advance cutting bridge floor, be arranged seam, or with compared with
Soft pave-load layer absorbs crack, or installs small-sized telescopic device to solve.In the case where larger longitudinal slope, such as it is not provided with
Consider the construction for adapting to conjugate vertically, is also easy to produce defect, causes to destroy.Telescopic device is along bridge floor longitudinal direction, even if stroke
Small, there is also the big problems of amount of deflection difference therefore structurally to attach the importance in telescopic device.Telescopic device is combined into beam body
It is undoubtedly the important means for improving its effective utilization etc. strong entirety.Existing overhead bridge construction telescopic device exists not mostly
With the defect or deficiency of degree, there is that structure is complicated, working procedure is more, installs also more complex, and some anchorings are unreliable, or need to use
More raw material, existing overpass telescopic device is commonly steel plate expansion joint, steel plate expansion joint due to steel plate deformed or
Anchoring piece such as falls off at the reasons, keeps its overhead bridge construction at high price, and skill is complicated, influenced by environment temperature it is bigger, for anchor
Firmware is inconvenient to fix, and can not measure to stroke after installation, cause no reliable data as reference, to bridge into
Row maintenance.Existing overhead bridge construction telescopic device simultaneously, when weld seam increases, biggish fragment is fallen in expansion joint,
Reduce the using effect of telescopic device.
In conclusion problem of the existing technology is:
(1) existing overhead bridge construction telescopic device cannot measure the size at expansion joint, cause without reliable
Data safeguard bridge, keep bridge damage serious as reference.
(2) existing overhead bridge construction telescopic device, when weld seam increases, biggish fragment is fallen in expansion joint,
Reduce the using effect of telescopic device.
