Description
Technical field
The present invention relates to bridge field, the covered structure of a kind of bridge expanssion joint.
Background technology
The road surface of bridge is often provided with expansion joint, in order to provide the allowance expanded with heat and contract with cold.For traffic safety and the serviceability of safeguarding bridge pavement, generally require and this expansion joint is carried out elastomeric objects filling or covering.Known mode is to use the materials such as gum elastic to cover or clog.But, the installation of this elastic rubber material needs the matrix of road pavement to carry out the reprocessing such as surface cutting, in order to install described elastomeric material in place.And this easily causes to produce these working positions when driving and damages and then damage road surface matrix.And the installation and removal for this elastomeric material are also required to expend a large amount of manpower and time cost.
Summary of the invention
It is an object of the invention to provide the covered structure of a kind of bridge expanssion joint, it can overcome defect of the prior art.
nullThe covered structure of the bridge expanssion joint according to the present invention，Cover at the road surface to bridge expanssion joint，Including the rubber body flushed with the level height of bridge pavement、It is positioned at the supporter within described rubber body、And can be towards and away from mobile and that structure is symmetrical two extension support members in described supporter，Wherein，Said two extend in support member each include can level is slided in the chute of described supporter horizontal extension head、The vertical extension connected with described horizontal extension head and the support arm connecting with the lower end of described vertical extension and extending towards adjacent bridge structure body，Wherein，Said two extends the end of support member and is provided with the support plate in order to abut with described adjacent bridge structure body，The end face of described support plate is provided with the shear pin being inserted in the shearing hole being arranged on described adjacent bridge structure body；Wherein, the vertical extension of two extended in support member is fixedly installed disengagable lock hook, another vertical extension is fixedly installed the disengagable locking dop of correspondence, being provided with cross section between described disengagable lock hook and described disengagable locking dop is oval action bars, and described action bars is rotatably supported in be fixed in the support rod being connected with described bridge structure body；Wherein, described disengagable lock hook includes being connected with adjacent bridge structure body and downward-sloping upper flexible extension and described upper flexible extension are connected vertical extension and the gib head protuberance of the lower end that is positioned at described vertical extension；Described disengagable locking dop includes connected with adjacent bridge structure body and acclivitous lower flexible extension, is positioned at the card head of described lower flexible extension end, when described disengagable lock hook is in mutual lock-out state with described disengagable locking dop, described gib head protuberance engages with the adjacent surface of described card head thus realizes linking locking, now, the oval major axis of the cross section of described action bars is horizontal direction；When the major axis that described action bars rotates the ellipse to cross section is vertical direction, the adjacent surface of described gib head protuberance and described card head departs from thus realizes unlocking, now, said two extension support member can make described support plate be pressed on adjacent bridge structure body and make in the shearing hole that described shear pin is inserted into correspondence under the effect of the top pressure spring being located at therebetween；The outside in described shearing hole is provided with guiding surface, and the end of described shear pin is provided with described guiding surface to the importing inclined-plane coordinated, and described shear pin may utilize described importing inclined-plane and can the cooperation of guiding surface be successfully inserted in the shearing hole of correspondence；Described chute left end is provided with elastic contact switch, the groove of described rubber body is provided with LED light, when described shear pin is inserted in the shearing hole of correspondence, the horizontal extension head in left side is in leftward position, and contact with described elastic contact switch, the most described LED light lights, to point out described shear pin to have been inserted in the shearing hole of correspondence.
Pass through the present invention, can elastic back down and two support arm parts away from each other owing to being provided with, by coordinating with the supported hole on the side of matrix and the elastomeric material supporting at road surface in place and can be flushed with road surface with the friction of matrix side by end card.And this device is easily installed, reason is, it is before the mounting by being arranged on the sealed of the hook part between two support arms and card head member, enable to two support arms and be in contraction state close to each other, therefore it is easy in the gap being successfully inserted between matrix, when described covered structure is secured in place by needs, be there is the elliptic cross-section action bars of long shape shaft by operation, enable to described hook part and card head member disengages, thus by the elastic top opening force of elastic top splenium part, the end of two support arms is pushed up and press to matrix side to realize fixing.More importantly, when the described action bars with elliptic cross-section is in the contraction state vertical with described disengaged condition, by extruding or push said two support arm opposite to each other, said two support arm can be close to each other and make described hook part and the deformation of dop component elasticity be changed into locked state from disengaged condition thus described covered structure is converted to contraction state.This can carry out the conversion operation of this contraction state when transporting described covered structure manufacturing complete, it is also possible to takes when covered structure is removed from flexible gap by needs.This is to have the arranging of respective guiding surface being engaged with each other time close to each other and realize by having the setting of the flexible rod portion tilted toward each other from respective arm and hook part and card head member by pushing automatically into the performance of locked state.And by arranging described action bars when being in described plumbness, it allows described hook part to move enough amounts to allow chain conjunction of described hook to disengage towards this action bars, and pushing said two support arm and be close to each other so that described action bars can servo-actuated or slave mode be followed freely rotatable to avoid interference with described sealed action when entering locked state.Whole apparatus structure is simple, runs ingenious, it is possible to operate to realize installation and removal effect easily, thus save time and the cost of labor of installation and removal, and uses reliable, stabilized structure.
