Problems solved by technology

The existing cable-bearing bridge towers are not only complex in structure, difficult to construct, and use a lot of construction materials, but also the structural design and force distribution of the bridge are not reasonable enough, and the appearance of the bridge is relatively dull and monotonous, which is not coordinated with the bridge environment. Affects the beauty of the bridge

Embodiment

[0024] a kind of like Figure 5 to Figure 9 The cable tower of the shown pan flute type cable load-bearing bridge of the present invention includes a cable tower base 1 and a tower body 2, and the tower body 2 includes two stepped sub-towers 21 that are symmetrically distributed along the bridge transverse center line L1, each The stepped sub-tower 21 is composed of the inner main tower 22, the first auxiliary tower 23 outside the main tower 22, and the second auxiliary tower 24 outside the first auxiliary tower 23. The connecting piece 3 is connected with the first auxiliary tower 23, and the first auxiliary tower 23 is connected with the second auxiliary tower 24 through three connecting pieces 3 distributed roughly evenly along the height direction, and each connecting piece 3 adopts a fixed connection piece (also Hinged joints are available). The heights of the main tower 22 , the first auxiliary tower 23 , and the second auxiliary tower 24 descend successively in a step-...

Abstract

The invention especially discloses a cable support tower of a cable load-bearing bridge, which comprises a cable support tower base and a tower body, wherein, the tower body comprises two stepped sub-towers which are symmetrically distributed; the stepped sub-towers comprise main towers and auxiliary towers the height of which is lower than that of the main towers; and the auxiliary towers are positioned outside the main towers, the main towers are connected with the auxiliary towers through connecting pieces, and the main towers of the sub-towers are connected through lower crossbeams. The cable support tower of the cable load-bearing bridge has the advantages of large rigidity, good stability and low construction cost and the like and is convenient to construct.

Description

technical field [0001] The invention relates to a component part of a bridge, in particular to a cable tower of a cable load-bearing bridge. Background technique [0002] With the rapid development of my country's transportation industry, a large number of bridges across rivers and canyons, as an important part of road traffic, have been or are being built one after another. At present, there are various structural forms of cable-bearing bridge towers at home and abroad. For example, the cable-stayed bridge tower body forms include single column, A-type and inverted Y-type along the longitudinal bridge direction, and single-column shape along the transverse bridge direction. Column type, double column type, door type, H type, A type, jewel type or inverted Y type, etc.; the tower body of the suspension bridge has a truss type (see figure 1 ), rigid construction (see figure 2 , image 3 ), combined (see Figure 4 )Wait. The existing cable-bearing bridge towers are not o...
