Description
Technical field
This utility model relates to bridge construction technical field, particularly relates to a kind of bridge foldable telescopic seam cover plate.
Background technology
For meeting the requirement of bridge floor deformation, prevent that variations in temperature from causing expand with heat and contract with cold, concrete shrinkage and the factor such as deformation, the live loading broken ring to bridge structure, ensure that vehicle travels smoothly, generally between two beam-ends, expansion joint is set between beam-ends and abutment or in the articulated position of bridge simultaneously.Bridge expanssion joint is to ensure that the important device of bridge structure safe, is also the weak part of bridge superstructure, directly bears the repeated action of vehicular load, is exposed in the Nature more again, is subject to the impact of various natural cause.Generally, expansion joint end face uses cover plate covering protection expansion joint internal structure.But being as the increase of service life, expansion joint interior waterproof water sealing structure is aging, damage, it is necessary to expansion joint is made regular check on, repairs, now need to get off detachable cover plate.The dam used in prior art is all integral plate, need to, by carrying out the service work at expansion joint after cover plate overall pulling down, dismount loaded down with trivial details during the maintenance of expansion joint, and each operating time is longer, all can cause affecting traffic for a long time；Simultaneously bridge stepped portions or cover plate cannot be installed because deformation causes faulting of slab ends position to cause, even if installing reluctantly, also resulting in protected effect not good, and being easily damaged.
Utility model content
This utility model purpose is to provide a kind of bridge foldable telescopic seam cover plate, solves prior art cover plate dismounting difficulty, it is easy to damage, the technical problem that protected effect is not good.
This utility model solves technical problem and adopts the following technical scheme that a kind of bridge foldable telescopic seam cover plate, including securing cover plate and operation cover plate, and by rotating shaft connecting portion that described securing cover plate and operation cover plate couple together；Wherein, described securing cover plate is provided with fixing device, dam is fixedly installed on bridge end face；Described securing cover plate is arranged on the side of bridge expanssion joint, and described rotating shaft connecting portion and described securing cover plate homonymy are arranged on the side of bridge expanssion joint；Described operation cover plate is laid on bridge expanssion joint, covers whole bridge expanssion joint, and with rotating shaft connecting portion for axis rotation.
Preferably, described rotating shaft connecting portion is that hinge is hinged.
Preferably, described operation cover plate is two, is arranged on securing cover plate both sides, and is connected by rotating shaft connecting portion.
Preferably, described operation cover plate is 45 °～180 ° with the angle that rotating shaft connecting portion is axis rotation.
Preferably, on described operation cover plate, a side end relative with rotating shaft connecting portion is set to ramp structure.
Preferably, the side end described securing cover plate being not connected with operation cover plate is set to ramp structure.
Preferably, described fixing device includes the water-proof nut being embedded in bridge end face and the CARBURIZING FURNACE FOR STAINLESS FASTENER being connected with this water-proof nut.
Preferably, relative with rotating shaft connecting portion on a described operation cover plate side end is provided with handle.
This utility model has the advantages that
By dam being set to securing cover plate and operation cover plate two-part structure, and utilize rotating shaft connecting portion to be coupled together by two parts, form foldable cover plate, by securing cover plate, whole dam is fixed on bridge end face, it is operated by cover plate to realize opening, closing with rotating shaft connecting portion for axis rotation, it is simple to expansion joint is overhauled and safeguards.This utility model dam simple in construction, easy to use, durable, it is simple to operation, reduce the time cost to the maintenance at expansion joint, maintenance, reduce the influence time to traffic.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section that this utility model bridge foldable telescopic seam cover plate is arranged on bridge expanssion joint.
In figure, labelling is illustrated as: 1-securing cover plate；2-operates cover plate；201-inclined-plane；3-rotating shaft connecting portion；4-fixes device；5-bridge end face；6-expansion joint.
Detailed description of the invention
