Description
Technical field
The invention belongs to technical field of bridge, are concretely related to a kind of metal damp type girder falling and subtract shock insulation branch
Seat.
Background technique
Earthquake can do great damage to the structure of science of bridge building: Bridges During Earthquake structure wink when especially earthquake magnitude is higher
Between bear compared with big load, less serious case can cause to generate dislocation between the beam body and bridge pier that constitute bridge, heavy then cause beam body relative displacement
Its beam body falls off when more than beam-ends shelving length, causes earthquake region transportation lifeline to cut off, causes the great difficulty of disaster relief work, make
Secondary disaster aggravates, and generates huge economic loss.
Current vibration absorption and isolation support mainly passes through the setting structures such as limited block or drag-line and realizes girder falling function, but this
A little rigidities of structure are all bigger, and larger can also generate very big impact since bridge superstructure is self-possessed and carry when earthquake occurs
Lotus leads to rigid member damage inactivation, cannot play the role of restrainer.And existing seismic isolation device all passes through mostly
Between constituting the upper and lower support plate of support and being sandwiched in spherical crown liner plate between the two setting by wearing plate that a sliding layer is formed with
Realize that shock insulation consumes energy function, and friction material dynamic friction coefficient is generally individually smaller than 0.05, and as to increase its fast for movement velocity
Speed reduces, and sets up defences demand far from the higher regional bridge of earthquake intensity is met.
Summary of the invention
It can effectively prevent to fall the metal damping that beam, damping capacity are good, energy consumption is strong it is an object of the invention to provide one kind
Formula girder falling vibration absorption and isolation support.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of metal damp type girder falling vibration absorption and isolation support, structure include the upper bracket plate for constituting support, lower support plate and set
It is placed in spherical crown liner plate between the two；It is characterized by: opposite between the upper bracket plate and lower support plate slide to two sides
It is provided with shearing mechanism；Girder falling mechanism is provided between the upper and lower support plate of support corresponding with the shearing mechanism.
In addition, constituting a kind of above-mentioned additional technical feature of metal damp type girder falling vibration absorption and isolation support further include:
--- the girder falling mechanism damps tenon row by the metal for being fixed on the lower support plate side and is connected to the metal
The stretching assembly damped between tenon row and the upper bracket plate is constituted；Wherein, the structure of metal damping tenon row include cylinder plate-laying,
The tenon that several one ends can be fixed with the lower support plate side, the other end can be fixedly connected with the cylinder plate-laying
Column is formed；
--- the stretching assembly is stayed structure；
--- the stretching assembly is to be made of half-round metal battened construction；
--- the lath be single-layer metal lath or multiple layer metal slab at composite slats structure；
--- it is respectively arranged between the upper bracket plate and spherical crown liner plate, between spherical crown liner plate and lower support plate by stainless steel
The friction pair for the wearing plate composition that the high molecular materials material such as plate and nylon is formed；
--- the cylinder plate-laying is that side is welded to connect with the tenon column, the other side is provided with and constitutes described stretch for fixed
The gap through one side of mechanism, which is more convenient for, and its plastic deformation is easy to absorb impact force.
A kind of metal damp type girder falling vibration absorption and isolation support provided by the present invention compared with prior art, has following excellent
Point: first, due to being provided with shearing mechanism and girder falling mechanism simultaneously in the structure of the support, it can effectively improve composition
The bearing performance of shock loading between the upper and lower support plate of the support, effectively avoids the generation for falling beam phenomenon；Second, due to constituting
The girder falling mechanism of the support by be fixed on lower support plate side metal damp tenon row and be connected to the metal damping tenon row with
Stretching assembly between the upper bracket plate is constituted, and when seismic force sets up defences maximum horizontal power greater than support, clipping apparatus is destroyed, and is led to
Crossing metal damping tenon plastic deformation and the secondary damping force provided of sliding of friction reduces earthquake shock load, is being tensioned traction cable
Before avoid bearing biggish shock loading causing to fail, increase support reliability；The gold when support movement to design maximum displacement
Belong to and damps anti-fall beam assembly tensioning, restrainer；Third, since if metal damping tenon row's dry friction damping tenon can be distinguished by bolt
It is connect with lower support plate and stretching assembly one end；Fixation is bolted in the stretching assembly other end and upper bracket plate, thus will
Metal damps anti-fall beam assembly and support is connected as entirety, convenient for replacing after shake, avoids the high expense of integral replacing support bring
With；Fourth, due to being respectively arranged with stainless steel plate between upper bracket plate and spherical crown liner plate, between spherical crown liner plate and lower support plate
The friction pair of the wearing plate composition formed with high molecular materials materials such as nylon, so that the friction is secondary to have creep-resistant property simultaneously
The good feature with self-lubricating property, and also have coefficient of friction high and stablize, support can be guaranteed in conventional operating condition and earthquake
Preferable damping action can be played under operating condition.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of metal damp type girder falling vibration absorption and isolation support of the present invention；
Fig. 2 is A-A cross section structure schematic diagram of Fig. 1.
Specific embodiment
With reference to the accompanying drawing to a kind of structure and work of metal damp type girder falling vibration absorption and isolation support provided by the present invention
It is described in further detail as principle.
It as shown in Figure 1, 2, is a kind of structural representation of metal damp type girder falling vibration absorption and isolation support provided by the present invention
Figure.The structure for constituting the support includes upper bracket plate 11, lower support plate 12 and is set to spherical crown liner plate 13 between the two；In upper branch
