Anti-drawing structure of support of straddle rail beam

Abstract

An anti-drawing structure of a support of a straddle rail beam is arranged between an upper support plate and a lower support plate; upper support plate guide plates are perpendicular to upper supportplate anti-drawing plates; the upper support plate guide plates and the upper support plate anti-drawing plates are respectively arranged at the two ends of the upper support plate in the horizontaldirection; lower support plate lugs are respectively arranged at the two ends of the lower support plate in the horizontal direction; rotary sliding blocks are arranged between the lower support platelugs and the upper support plate anti-drawing plates; the lower surfaces of the lower support plate lugs are matched with the upper surfaces of the rotary sliding blocks; the upper surfaces of the upper support plate anti-drawing plates are matched with the lower surfaces of the rotary sliding blocks; and the upper surfaces of the rotary sliding blocks are arc surfaces and the lower surfaces of the rotary sliding blocks are flat surfaces or the lower surfaces of the rotary sliding blocks are arc surfaces and the upper surfaces of the rotary sliding blocks are flat surfaces. By virtue of the rotary sliding blocks, the upper support plate anti-drawing plates and the lower support plate lugs, the anti-drawing structure realizes the large displacement, low friction sliding and anti-drawing function of the support, thereby effectively improving the force-bearing safety and reliability of the structure of the support and the convenience of processing. The anti-drawing structure of the support of the straddle rail beam meets the need for the anti-drawing function of the support of the straddle rail beam.

Description

technical field [0001] The invention belongs to the technical field of bridge structures or buildings, and relates to a pullout-resistant structure of a straddle-type track beam support. Background technique [0002] Straddle-type monorail traffic is a new form of modern urban rapid rail three-dimensional traffic, with low noise, strong climbing ability, small turning radius, fast and convenient, less land occupation, low cost, not restricted by terrain, and conducive to environmental protection, etc. Many advantages are a new trend in the development of urban rail transit in the future. [0003] As a two-way flexural member, the straddle-type monorail traffic track beam not only bears the vertical load and horizontal load (centrifugal force, wind force, etc.) of the train, but also bears a large torsional load, and also serves as a track for the train. As an important part of the straddle monorail traffic track beam, the straddle type track beam support is the key to ensur...

Problems solved by technology

[0006] The anti-pull function of the existing PC track beam cast steel support is to realize the tensile function of the support through the hinge structure between the upper pendulum and the lower pendulum, and at the same time realize the horizontal displacement of the support through the gap between the hinge shaft and the hinge shaft hole. However, in practical applications, there are also disadvantages such as the line contact between the hinge shaft and the hinge plate, uneven force, and small adaptive displacement.
