Problems solved by technology

If beams are used for connection, brackets need to be erected during construction, while concrete for beams and tower columns at the beams and prestressed beams for tension beams are poured at the same time. The construction period is long and the process is complicated; The tall and tall appearance of the bridge tower has a certain influence, which destroys the overall aesthetic feeling of the bridge to a certain extent
If the diaphragm connection is used, it can solve the impact of the beam, especially the multi-beam connection on the bridge landscape, but the construction is also difficult and the force is complicated, and it affects the airiness of the local space at the bridge tower

Embodiment 1

[0052] The present invention provides a bridge tower with space bracing between the tower limbs and a construction method thereof. Composed of column 5, upper tower column diagonal brace 6, lower tower column and tower limb partition plate 7, and bridge pylon crossbeam and haunch 8; figure 1 , image 3 , Figure 5 to Figure 13 shown.

[0053] The bridge tower with space braces between the tower limbs described in this implementation is in the form of a diamond-shaped bridge tower, the height of the lower tower column 2 is 55m, the height of the upper tower column 5 is 97m, and the overall height of the bridge tower is 152m; the height of the bridge tower cap 1 is 5.0 m, the width across the bridge is 29.0m, and the width along the bridge is 19.0m.

[0054] In this embodiment, the lower tower column spacer plate 7 is set between the two tower legs of the lower tower column 2, and the tower column spacer plate 7 is 4.0m thick, which is in the shape of a "V"; , the lower towe...

Embodiment 2

[0072] The present invention provides a bridge tower with space bracing between the tower limbs and a construction method thereof. Composed of column 5, upper tower column diagonal brace 6 and bridge pylon crossbeam and haunch 8; figure 2 , Figure 4 , Figure 9 ~ Figure 13 shown.

[0073] The pylon with space braces arranged between the pylon limbs in this embodiment is in the form of a diamond-shaped pylon with a total height of 144m, and a pylon crossbeam 4 is set below the main girder, and the pylon is divided into upper and lower parts; Among them, the height of the lower tower column 2 is 62m, and the height of the upper tower column 5 is 82m; the height of the bridge tower cap 1 is 5.0m, the width of the bridge is 34.0m, and the width of the bridge is 19.0m.

[0074] The bridge beam 4 of the bridge tower adopts a box section, with a height of 6.0m, a width of 6.0m, and a wall thickness of 1.2m; The bearing capacity of the top section of the pylon column 2;

Abstract

The invention relates to the technical field of bridge structures, in particular to a bridge tower with space inclined struts arranged between tower limbs and a construction method. The bridge tower type comprises a bridge tower bearing platform for fixing a bridge tower, diamond-shaped tower columns are installed on the bridge tower bearing platform and comprise lower tower columns and upper tower columns, and bridge tower cross beams are arranged between the lower tower columns and the upper tower columns, and thebridge tower is characterized in that a lower tower column inclined strut is arranged between the lower tower columns, an upper tower column inclined strut is arranged between the upper tower columns, and the lower tower column inclined strut and the upper tower column inclined strut comprise at least one set of crossed inclined supporting rods. According to the bridge tower structure form provided by the invention, on the basis of not increasing the construction period and the construction difficulty, the space inclined struts are arranged at the intersections of the tower bottom and the upper tower columns, so that the transverse calculation length of the tower columns is reduced, the transverse stability is improved, and the shape of the bridge tower is richer in artistic aesthetic feeling; and the relationship between the architectural modeling and the structural safety can be well balanced.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a bridge tower with space braces arranged between tower limbs and a construction method thereof. Background technique [0002] With the development of economy, the advancement of science and technology, and the improvement of living standards, human beings have put forward higher requirements for the surrounding living environment, and bridges, as large permanent public buildings, are safe, practical and economical. Aesthetic properties are also gaining more and more attention. [0003] As a cable-supported bridge, the cable-stayed bridge not only has good spanning ability, but also is one of the main bridge types of long-span bridges, and the combination of beams, towers, and cable-stayed cables forms a bridge with a clear, The simple and smooth composition has a beautiful form that combines function and form; coupled with the bright lines of force of the cable stays,...
