Description
Technical field
This utility model is related to field of steel structure, more particularly to a kind of Anti-seismic bridge steel structure.
Background technology
Steel construction is the structure being mainly made up of steel material, is one of main building construction types.Structure mainly by
The component such as girder steel, steel column, steel truss composition made by shaped steel and steel plate etc., generally adopts weld seam, spiral shell between each component or part
Bolt or rivet interlacement.Because which is conducted oneself with dignity relatively gently, and easy construction, it is widely used in the fields such as large-sized workshop, venue, Super High.Steel
The characteristics of material be intensity it is high, from heavy and light, integral rigidity be good, deformability is strong, therefore be used to building large span and superelevation, extra-duty
Building is particularly suitable；Material homogeneity and isotropism are good, belong to perfect elastic body, best suit the substantially false of common engineering mechanics
It is fixed；Material plasticity, good toughness, can have moderate finite deformation, can bear dynamic load well；Construction period is short；Its industrialization degree
Height, can carry out the high Virtual production of mechanization degree.Steel construction should study high strength steel, greatly improve its yield point strong
Degree；In addition the shaped steel rolled by new varieties, such as H profile steel (also known as wide width wing edge shaped steel) and T steel and profiled sheet etc. are with suitable
Answer the needs of longspan structure and high-rise building.Heat bridge lightweight steel construction system also whether there is in addition, building is not energy-conservation in itself,
This technology solves the problems, such as the cold-heat bridge of building with cleverly special joining part；Jack truss structure make cable and upper and lower conduit road from
Pass through in wall, construction finishing all facilitates；Existing bridge steel structure is imitated due to lacking damping or damping when long-time is used
It is really bad, often result in deformed damaged or the fatigue fracture of steel construction.
Based on above reason, a kind of Anti-seismic bridge steel structure is needed to be devised, by base and structural beams sheet
The middle part of body arranges damping spring structure, can be very good to reduce impact of the vibrations to steel construction, by arranging nylon composite plate
Damping spring is padded, the damage that damping spring and base excessive friction are caused is prevented；By arranging rubber washer, excessive shake is prevented
When dynamic, base direct collision structural beams body is caused to cause the damage of base or structural beams, using more convenient, i.e., a kind of antidetonation
Type bridge steel structure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of Anti-seismic bridge steel structure.
This utility model is to be achieved through the following technical solutions：
A kind of Anti-seismic bridge steel structure, including base and structural beams body, the base and structural beams body are by subtracting
Shake spring connection, the both sides up and down of the damping spring are lined with nylon composite plate；The nylon composite plate lower surface pad is in base
Boss on, the upper surface pad of the nylon composite plate in the groove of structural beams body, around the damping spring arrange
There is a protection lasso, on the corresponding boss of the protection lasso, be cased with rubber washer；The also fixation of the outside of the structural beams body sets
Otic placode is equipped with, two positioning inside grooves in the middle part of the structural beams body, are offered.
Further, the protection lasso and structural beams body are integral type structure, improve the globality of structure, and it is right to be easy to
Damping spring cross spacing, prevents damping spring from coming off.
Further, bolt hole is provided with the otic placode, be easy to being connected between steel construction or arranged side by side,
Improve the globality of steel construction.
Further, the slotted eye lower end of the positioning inside groove is set to rounding off, and the stress for reducing structural beams body is rotten
Erosion, improves the service life of structural beams body.
Further, the contact surface of the nylon composite plate and damping spring is provided with circular groove, is easy to damping bullet
Spring is positioned.
Compared with prior art, the beneficial effects of the utility model are：It is this utility model simple structure, reasonable in design,
By arranging damping spring structure at the middle part of base and structural beams body, can be very good to reduce shadow of the vibrations to steel construction
Ring, damping spring is lived by arranging nylon composite plate pad, prevent the damage that damping spring and base excessive friction are caused；By setting
Rubber washer is put, when preventing excessive vibrations, is caused base direct collision structural beams body to cause the damage of base or structural beams, is made
With more convenient.
