Abstract

A shock-absorption tension-compression ball type support capable of preventing beam falling includes five large parts, namely a bottom base plate, a lower base plate, a middle base plate, an upper base plate and a tensile screw. The key parts of the shock-absorption tension-compression ball type support capable of preventing beam falling include longitudinal and transverse anti-beam-falling check blocks, tensile nuts, longitudinal and transverse tensile friction pairs, a spherical anti-pressure friction pair, a spherical tensile friction pair, longitudinal and transverse guide friction pairs, a transverse limiting friction pair, a transverse limiting plate and the like. The support can bear press loads, tension loads and horizontal loads transmitted by a beam structure, the displacement requirements of the beam structure under normal use conditions and seismic conditions are met, and the support has the advantages that rotation is flexible, force transmission of the structure is uniform and a force transmission route is definite.

Description

technical field [0001] The invention belongs to the technical field of bridge structures or buildings, and relates to a shock-absorbing tension-compression spherical bearing with the function of anti-falling beams. Background technique [0002] With the rapid development of my country's passenger dedicated lines, high-speed railways, expressways and urban interchanges, the structural types of bridges have shown a diversified development trend, and other beam types with floating structures such as oblique girders, curved girders, and cable-stayed bridges have emerged. . Under the action of temperature creep, wind load and other factors, these bridge structures will produce tensile forces opposite to the direction of gravity on some bridge nodes, such as the side fulcrums of continuous beams, the acute angle parts of skew beams and the suspension of cable-stayed bridges. Support points, etc., thus requiring a structure that can withstand vertical tension between the bridge and...
