When head is in mutually locking state, the gib head protuberance engages with the adjacent surface in the dop portion and links locking so as to realize,
Now, the oval major axis of the cross section of the action bars is horizontal direction；When the action bars rotate it is ellipse to cross section
When circular major axis is vertical direction, the adjacent surface in the gib head protuberance and the dop portion departs from so as to realize unblock, this
When, described two extension support members can cause the support plate to compress in the presence of top pressure spring therebetween
On adjacent bridge structure body and the shear pin is sheared in hole corresponding to being inserted into；On the inwall in the shearing hole
The magnet of the adsorbable shear pin is installed, when the shear pin is by the magnet adsorption, the rubber body can be made steady
Guan County is mounted in bridge expanssion joint.
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.
