Description
Technical field
This utility model belongs to bridge earthquake resistance technical field, particularly to a kind of embedded type bridge limiting shock resistant dress
Put.
Background technology
In recent decades, Chinese bridge modernization is flourish, and concrete-bridge, steel bridge are built in a large number.With
Front highway and railway norm be spacing for bridge and antishock device not requirement, and therefore, bridge structure is the most not
Spacing and antishock device is set.
Along with the continuous fast development of domestic economy, bridge is used and proposes new requirement.Not only include
Requirement in terms of bearing capacity, with the new demand included in terms of serviceability and antidetonation.
At present, the stopping means of bridge mainly uses following two kinds of methods: pre-buried by bar planting method at pier stud
Steel plate, upwards welds stiffener as bridge falling-off prevention measures around pre-embedded steel slab；Second, at beam body abdomen
By bar planting method pre-embedded steel slab outside plate, around pre-embedded steel slab, weld downwards stiffener as falling-off prevention measures.
Both approaches cannot coordinate the deformation of beam body and pier stud, and security performance is relatively low, it is impossible to meet code requirement.
For some steel box girder bridges, vibrate this problem and be especially apparent in steel bridge, have a strong impact on use process
In pedestrian and the comfort of driver.
For some curved bridges and swash plate beam bridge, curved bridge due to the unbalance loading of vehicle, bridge simultaneously by moment of flexure with
And moment of torsion so that bearing is easy to conjugate；Skew Plate Bridges is due to temperature and unbalance stress during using
Even, bearing is also easy to displacement.
Therefore, those skilled in the art need to study a kind of spacing, limiting shock resistant device that effect of energy dissipation is good.
Summary of the invention
The purpose of this utility model be to provide a kind of spacing, effect of energy dissipation good, it is possible to coordinate beam body and assist with pier stud
The embedded type bridge limiting shock resistant device of modulation shape.
In order to realize this purpose, this utility model be the technical scheme is that
This embedded type bridge limiting shock resistant device, including the pre-buried steel case being embedded in beam body, at pre-buried steel case
Inner chamber is provided with anchor block, is filled with cushion in the space between anchor block and pre-buried steel case, and anchor block is embedded in
There is the connecting rod extended in bent cap block, fixed by nut between connecting rod and bent cap block.
It is set with steel pipe on the outer wall that above-mentioned connecting rod contacts with beam body, bent cap block.
Above-mentioned cushion includes that horizontal cushion and longitudinal buffer layer, horizontal cushion level are laid on anchor block
Top and bottom, its thickness is 50～60mm, and longitudinal buffer layer is disposed longitudinally on anchor block and pre-buried steel chamber interior wall
Between space in, its thickness is 50～80mm.
Embedded type bridge limiting shock resistant device of the present utility model, utilizes connecting rod bent cap block and beam body to be connected
Connect, and utilize be arranged on the anchor block in pre-buried steel case and nut by connecting rod respectively with beam body, bent cap block
Fixing, it is achieved the connection between block and beam body, spacing to beam body, simultaneously by loading in pre-buried steel case
Cushion, plays the effect of energy dissipation in inside, and the design of this utility model structure is simple, can meet
Bridge earthquake resistance requirement under different earthquake level, beam body coordinates stress, again sending out of restrainer accident with pier stud
Raw, the connecting rod in beam body can be back-outed in later period maintenance is reinforced in addition, it is simple to the maintenance and reinforcement in later stage,
Do not affect later stage replacing time envelope maintenance and reinforcement operation, and spacing, effect of energy dissipation good, it is possible to coordinate beam body
With pier stud compatible deformation.
