Embodiment Construction

[0038] a kind of like figure 1 , figure 2 , Figure 5 ~ Figure 8 The shown hyperbolic bridge pier of the present invention comprises a pier substructure 2, a pier bifurcation structure 3 and a pier top longitudinal connection structure 4 located on the foundation cap 1 (fixed by a pile foundation 11), and the bridge pier bifurcation structure 3. The bottom is affixed to the top of the substructure 2 of the pier, and the bifurcated member 31 of the bifurcated structure 3 of the pier is affixed at the top of the pier through the longitudinal connection structure 4 of the pier top. The pier substructure 2 is provided with conventional diaphragms along the height direction of the pier according to the stability requirements.

[0039] Such as figure 1 , figure 2 , Figure 5 ~ Figure 8 As shown, starting from the foundation cap 1, viewed along the longitudinal direction of the bridge (i.e., the main direction), the length L of the bridge pier first gradually narrows with the ...

Abstract

The invention discloses a hyperbolic bridge pier and hyperbolic bridge pier and tower. The bridge pier comprises a bridge pier lower structure, a bridge pier bifurcation structure and a longitudinal linking structure, wherein, the bifurcation starting point of the bridge pier bifurcation structure is fixed on the top of the bridge pier lower structure; two bifurcation components of the bifurcation structure are fixed on the top of the bridge pier by the longitudinal linking structure; and the projections of the outer contour line of the bridge pier along the vertical direction on the bridge longitudinal and lateral directions are hyperbolic. The bridge pier and tower comprise the above bridge pier and a bridge tower, wherein the bridge tower comprises a bright tower bifurcation structure;the middle hollow part of the bright tower bifurcation structure forms a bright hole penetrated by the girder of the bright; the four bifurcation components of the bridge tower bifurcation structure are hinged or fixed to the above two bifurcation components of the bifurcation structure to form a quadrilateral with an upward hollow part along the bridge. The hyperbolic bridge pier and hyperbolic bridge pier and tower have the advantages of strong overall rigidity, good stability, convenient construction, wide application range, attractive appearance and good economy.

Description

technical field [0001] The invention relates to a composition structure of a bridge, in particular to a bridge pier tower with a special structure. Background technique [0002] With the rapid development of my country's transportation infrastructure construction, a large number of various bridges across rivers and canyons, as an important part of road traffic, are being frequently built. At present, the structure forms of cable-supported bridge towers at home and abroad include single-column, A-type and inverted Y-type in the longitudinal direction, and single-column, double-column, door-type, H-type, A-type, and so on in the transverse direction. Gem type or inverted Y type, etc. For bridges with flexible systems such as cable-supported bridges, improving the overall stiffness of the structure is a key factor affecting bridge design and construction. Moreover, as people pay more attention to the aesthetics of bridges, most of the bridges in the past were based on functio...
