Description
Technical field
The utility model belongs to bridge and building structure bearing technical field, is specifically related to the multidirectional activity tension and compression of a kind of central draw bar type spherical bearing.
Background technology
Along with the fast development of China Express Railway, speedway and city intersection, the form of structure of bridge presents diversified development trend, emerge large quantities of bridges such as cant beam, curved beam, cable stayed bridge and other with floating structure, under the effect of the factors such as these bridge constructions are crept in temperature, wind carries, on some Bridge Joints, may produce the pulling force contrary with gravity direction, as the limit fulcrum of continuous beam, the suspension support point of the acute angle position of obliquely-intersected beams and cable stayed bridge etc., thus require bridge must arrange can bearing tension structure.Traditional way is to carry out balance pulling force upwards by apply counter weight construction at Liang Tishang, increasing counter weight construction has not only increased the constant load of bridge itself, increase considerable construction costs simultaneously, especially for edge-beam across waters large-scale cable stayed bridge all the more so.Employing can be born vertical pressure, and to bear again to the tension compression bearing of upper pulling force be simple, economic solution route.
At present, the domestic tension compression bearing that has occurred multiple pattern, as periphery bears formula benzvalene form tension compression bearing, side direction bears formula ball-type tension compression bearing and Bolt Connection and bears the center tension formula ball-type tension compression bearing of structure, but in all defects of various degrees of actual use procedure, as tensile structure arranges the unreasonable flexibility that bearing rotates that limited, tension face contact gap is larger, abutment pressure and the conversion of pulling force stress system produce comes to nothing, tensile structure adopts bolt combination body structure easily to produce the defects such as local stress, these defects are buried potential safety hazard to the operation of bridge construction.Periphery bears the both sides that bear mechanism and be arranged on bearing of formula benzvalene form tension compression bearing, for the flexibility that guarantees that bearing rotates, bear position contact surface larger gap need be set, bearing easily produces the phenomenon of coming to nothing when carrying out pressure and pulling force conversion, cause the impact of contact surface, unfavorable to structure stress; The bearing plate of bearing adopts rubber components, has the application life of the problems affect bearing of ageing of rubber.Side direction bears the both sides that bear mechanism and be arranged on bearing of formula ball-type tension compression bearing, stationarity during for assurance abutment pressure and pulling force conversion, the gap that bears mechanism's contact surface is less, flexibility and all close contacts of rotation consequence drawing mechanism that bearing rotates have so just been limited, contact surface be local contact even for line contacts, unfavorable to structure stress; The stretch-proof organization that Bolt Connection bears the center tension formula ball-type tension compression bearing of structure is the tension screw rod that is arranged on bearing center, the screw thread difficulty of processing of screwed hole of centre that is positioned at lower seat board center bearing tension is larger, once screw thread processing is wrong or inefficacy will cause whole lower seat board to scrap, the difficulty of repairing is larger, and both sides bear guide strip and adopt bolt and upper base plate main body to be connected in, cause that attachment bolt place structure partial stress is excessive to be easily pulled off or to be out of shape; To some special bridge constructions, not only require bearing have the resistance to tension direction across bridge that also requirement is can simultaneous adaptation bridge construction larger and vertical bridge to horizontal movement.Domestic existing multidirectional movable tension compression bearing is on the basis of one-way movable tension compression bearing, to increase the requirement that bears gap between limiting plate and lower seat board and meet lateral displacement, this structure is only applicable to less lateral displacement, for the multidirectional freely movable bearing of large (lateral displacement is greater than 10mm) of lateral displacement, if continue to adapt to by the lateral clearance of increase direction across bridge guide strip and middle seat board and upper base plate the lateral displacement of beam portion,, due to excesssive gap, be unfavorable for that the entirety of seat structure is stressed.
Summary of the invention
