Description

Technical Field

[0001] The utility model relates to the field of T-beam connection, in particular to an ultra-long T-beam connection device. Background Art

[0002] At present, the connection methods of the joints in the process of widening the T-shaped main beams of the new and old bridges mainly include flexible connection (hinging) and rigid connection; when the main beams of the new and old bridges are hinged, the connection stiffness is very small. At the hinged structure, such unfavorable factors as shrinkage and creep of concrete materials, foundation settlement difference and deflection difference caused in the later operation can be released in the form of differential deformation; because the connection is hinged and cannot bear the bending moment, when the combined effect of the above unfavorable factors exceeds a certain range, certain diseases will appear at the connection, and the later maintenance cost is relatively high; rigid connection is mainly achieved by transverse diaphragms; compared with hinges, rigid connections can avoid the complex structure of hinges, avoid setting expensive longitudinal expansion joints, and ensure the advantages of smooth bridge deck and comfortable and safe driving. However, for rigid connections, the shrinkage and creep of concrete, the foundation settlement difference and the structural deflection difference caused by the vehicle load will generate internal forces at the connection, which will have a great impact on the overall and local stress of the structure, and this impact will become more significant as the span increases;

[0003] In order to solve the above technical problems, a Chinese patent with the authorization announcement number CN215801123U discloses a new and old T-beam connection device; the utility model is proposed in the article to set a support plate and a support block between the first T-beam and the second T-beam to adjust the installation gap and make the support block fit the T-beam, and set a connecting plate to connect and fix the two T-beams to achieve overall connection force, improve the force strength, simple and compact structure, and convenient installation and construction;

[0004] Although the above device can connect and fix two sets of T-beams, due to the small contact area between the two sets of T-beams, when they are working and subjected to lateral shear force (strong crosswind weather), the two sets of T-beams are prone to misalignment, reducing the stability of the connection between the two sets of T-beams.
