Abstract

A cross-seat track beam support comprises an upper seat plate, a middle seat plate, a lower seat plate, at least one stepless heightening structure and base plate and drawing resisting structures arranged at two ends of the upper seat plate and the lower seat plate. The lower surface of the upper seat plate and the upper surface of the middle seat plate are planes in sliding fitness, the lower surface of the middle seat plate and the upper surface of the lower seat plate are curved surfaces in longitudinal rotating fitness, the lower seat plate is arranged on the base plate through the stepless heightening structures, each drawing resisting structure comprises an upper-seat-plate guiding plate, an upper-seat-plate drawing resisting plate and a lower-seat-plate lug, the lower-seat-plate lugis arranged in a space enclosed by the upper-seat-plate guiding plate and the upper-seat-plate drawing resisting plate, and a rotating slider is arranged between the lower-seat-plate lug and the upper-seat-plate drawing plate. By the arrangement, low-friction sliding, stepless heightening and replaceable functions of a support are realized, safety reliability of structural force and convenience in construction maintenance of the support can be effectively improved, and requirements of a cross-seat monorail traffic track beam on safety operation and construction convenience of the support aremet.

Description

technical field

[0001] The invention belongs to the technical field of bridge structures or buildings, and relates to 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 ensure the normal function of the stra...

Examples

Embodiment 1

[0065] Such as Figure 7 As shown, the lower part of the lug 8 of the lower seat plate of the pull-out-resistant structure is provided with a concave arc-shaped structure. The surface of the arc structure is covered with a friction plate with a low coefficient of friction and matches with the upward convex arc surface of the rotary slider 12 to form a rotary friction pair of the rotary slider to adapt to the longitudinal rotation of the upper beam.

[0066] The lower plane of the rotating slider 12 of the anti-drawing structure is coated with a friction plate with a low friction coefficient and matched with the stainless steel sliding plate coated on the upper surface of the upper seat plate tensile plate 14 to form a plane friction pair of the rotating slider. To accommodate the longitudinal displacement of the upper beam body.

Embodiment 2

[0068] Such as Figure 8As shown, the lower part of the lug 8 of the lower seat plate of the pullout-resistant structure is provided with a convex arc-shaped structure. The surface of the arc structure is covered with a friction plate with a low coefficient of friction and matches the upper concave arc surface of the rotary slider 12 to form a rotary friction pair of the rotary slider to adapt to the longitudinal rotation of the upper beam.

[0069] The lower plane of the rotating slider 12 of the anti-drawing structure is coated with a friction plate with a low friction coefficient and matched with the stainless steel sliding plate coated on the upper surface of the upper seat plate tensile plate 14 to form a plane friction pair of the rotating slider. To accommodate the longitudinal displacement of the upper beam body.

Embodiment 3

[0071] Such as Figure 9 As shown, the lower part of the rotating slider 12 of the anti-pullout structure is provided with a convex arc-shaped structure. The surface of the arc-shaped structure is covered with a friction plate with a low coefficient of friction and matches the upper concave arc surface of the upper seat plate tensile plate 14 to form a rotating friction pair of the rotating slider to adapt to the longitudinal rotation of the upper beam.

[0072] The lower surface of the lug 8 of the lower seat plate of the anti-drawing structure is covered with a friction plate with a low friction coefficient and matches with the stainless steel slide plate coated on the upper surface of the rotating slider 12 to form a plane friction pair of the rotating slider. To accommodate the longitudinal displacement of the upper beam body.
