Description
Technical field
The present invention relates to bridge field, specially a kind of covering device for expansion joint for municipal bridge.
Background technology
The road surface of bridge is often provided with expansion joint, to provide the allowance expanded with heat and contract with cold.For traffic safety and dimension
The performance of bridge pavement is protected, generally requires to carry out elastomeric objects filling or covering to this expansion joint.Known mode is
Covered or clogged using materials such as elastic caoutchoucs.But the installation of this elastic rubber material needs the matrix of road pavement
The reprocessing such as surface cutting is carried out, it is in place to install the elastomeric material.And this is easily caused when driving to these
Working position, which produces, damages and then damages road surface matrix.And the installation and removal for this elastomeric material are also required to expend greatly
Measure manpower and time cost.
The content of the invention
It is an object of the invention to provide a kind of covering device for expansion joint for municipal bridge, it can overcome prior art
The defects of.
According to the covering device for expansion joint for municipal bridge of the present invention, for being carried out at the road surface to bridge expanssion joint
Covering, including flushed with the level height of bridge pavement rubber body, the supporter inside the rubber body and
Can be towards and away from mobile and structure symmetrically in the supporter two extend support members, wherein, it is described two
Extend in support member it is each include can the horizontal extension head that the chute reclaimed water of the supporter is smoothly moved, with it is described
The vertical extension of horizontal extension head connection and it is connected with the lower end of the vertical extension and towards adjacent bridge knot
The support arm of structure body extension, wherein, guide rod is installed, two horizontal extension heads are installed in the guiding in the chute
On bar, the guide rod can make two horizontal extension heads keep stable when moving left and right, the end of described two extension support members
Portion is provided with the support plate to be abutted with the adjacent bridge structure body, and use is provided with the end face of the support plate
With the shear pin being inserted into the shearing hole for being arranged on the adjacent bridge structure body；Wherein, in two extension support members
The vertical extension of one is fixedly installed disengagable lock hook, another vertical extension be fixedly installed corresponding to can take off
Dop is determined in unlocking, and behaviour of the cross section for ellipse is provided between the disengagable lock hook and the disengagable locking dop
Make bar, the action bars is rotatably supported in the support rod being fixedly connected with the bridge structure body；Wherein, it is described to take off
Opening lock hook includes and the upper flexible extension that tilts down and the upper flexible extension connected with adjacent vertical extension
The gib head protuberance of connected vertical extension and the lower end positioned at the vertical extension；The disengagable locking card
Head includes connected with adjacent vertical extension and acclivitous lower flexible extension, positioned at the lower flexible extension end
The dop portion at place, when the disengagable lock hook is in mutually locking state with the disengagable locking dop, the gib head
Protuberance engages with the adjacent surface in the dop portion and links locking so as to realize, now, the ellipse of the cross section of the action bars
The major axis of shape is horizontal direction；When the oval major axis that the action bars is rotated to cross section is vertical direction, the hook
Head protuberance and the adjacent surface in the dop portion depart from so as to realize unblock, and now, described two extension support members can set
The support plate is caused to be pressed on adjacent bridge structure body and cause in the presence of top pressure spring therebetween
The shear pin is sheared in hole corresponding to being inserted into；Guiding surface, the end of the shear pin are provided with the outside of the shearing hole
The importing inclined-plane being engaged with the guiding surface is provided with end, the shear pin can utilize the importing inclined-plane and be oriented to oblique
The cooperation in face is sheared in hole corresponding to being successfully inserted at.
By the present invention, due to there is provided can elastic top open and two support arm parts away from each other, by with base
Supported hole on the side of body coordinates and can be by the elastomeric material at road surface by the friction of end card and matrix side
Supporting is in place and is flushed with road surface.And this device is easily installed, reason is, it is before the mounting by being arranged on two
Hook part and dop part between support arm it is sealed, enable to two support arms to be in contraction state close to each other,
Therefore it is easy in the gap that is successfully inserted between matrix, when needing to be secured in place the cladding system, passes through and operate tool
There is the elliptic cross-section action bars of long shape shaft, enable to hook part and the dop part to disengage, so as to by elastic top
The elastic top opening force of splenium part and by the end top pressure of two support arms to matrix side to realize fixation.More importantly, when
When the action bars with elliptic cross-section is in the contraction state vertical with the disengaged condition, by extruding opposite to each other or
Described two support arms are pushed, described two support arms can be close to each other and cause hook part and the dop component elasticity
Deform and be changed into locked state from disengaged condition so as to which the cladding system is converted into contraction state.This can manufactured
Finish and the conversion operation of this contraction state is carried out when transporting the cladding system, can also need cladding system from flexible
Taken when being removed in gap.This by pushing is by with from respective arm automatically into the performance of locked state
And the setting of flexible rod portion inclined toward each other and hook part and dop part when close to each other with being engaged with each other
Respective guiding surface sets to realize.And by setting the action bars when in the plumbness, it is permitted
Perhaps described hook part moves enough amounts to allow chain close of the hook to disengage towards the action bars, and described two pushing
Support arm is close to each other so that the action bars can be servo-actuated when entering locked state or slave mode is followed and freely rotated to keep away
Exempt to interfere the sealed action.Whole device is simple in construction, and operation is ingenious, can easily operate to realize that installation and removal are made
With so as to save the time of installation and removal and cost of labor, and use is reliable, stabilized structure.
