Abstract

FIELD: bridge building. SUBSTANCE: suspension bridge includes stiffening beam, load bearing cables placed on different sides from the lengthwise axis of the bridge and connected to the stiffening beam through cable suspensions being parallel to bridge face, and inclined to the vertical in bridge cross section at specified angle Φ, two waterside abutments and device for taking loads from brace. Stiffening beam walls are inclined to the vertical at the angle equal to the slope of cable frame suspensions. Upper and lower booms of stiffening beams are made under three options: 1) upper booms are placed in horizontal plane; 2) lower booms are placed in horizontal plane; 3) upper booms are placed in horizontal plane whilst lower booms are perpendicular to stiffening beam walls. EFFECT: higher stiffness. 3 cl, 3 dwg

Description

Изобретение относится к области мостостроения, в частности к мостам с тросовыми фермами. The invention relates to the field of bridge construction, in particular to bridges with cable trusses.

В качестве сооружения прототипа в настоящей заявке принято решение по патенту ФРГ N 836953, кл. E 01 D 11/00, опублик. 1952. As a construction of the prototype in this application, a decision was made on the Federal Republic of Germany patent N 836953, class. E 01 D 11/00, published. 1952.

На фиг. 1 изображен висячий мост, фасад; на фиг. 2 и 3 варианты его поперечных сечений. In FIG. 1 depicts a suspension bridge, facade; in FIG. 2 and 3 variants of its cross sections.

Висячий мост включает балки жесткости 1, несущие тросы 2, размещенные по разные стороны от продольной оси моста и соединенные с балками жесткости 1 тросовыми подвесками 3, параллельными по фасаду моста и наклоненными к вертикали в поперечном сечении моста на заданный угол Φ, два береговых пилона и устройства для восприятия распора, на фиг. не показанные. Suspension bridge includes stiffeners 1, bearing ropes 2, placed on opposite sides of the longitudinal axis of the bridge and connected to stiffeners 1 with cable suspensions 3, parallel to the facade of the bridge and inclined to the vertical in the cross section of the bridge at a given angle Φ, two coastal pylons and devices for receiving perception, in FIG. not shown.

Пунктиром на фиг. 1 показаны продольные и поперечные связи пролетного строения. The dotted line in FIG. 1 shows the longitudinal and transverse connections of the span.

Балка жесткости 1 включает стенку 4, верхние 5 и нижние 6 пояса. Стенка балки может быть конструктивно сплошной или решетчатой; пояса конструктивно сплошные. The stiffness beam 1 includes a wall 4, upper 5 and lower 6 zones. The wall of the beam can be structurally continuous or lattice; the belts are structurally continuous.

Стенки балок жесткости в варианте поперечного сечения моста (фиг. 2) выполнены с наклоном к вертикали на угол, равный углу наклона к вертикали подвесок тросовых ферм, а верхние пояса балок жесткости расположены в горизонтальной плоскости. При этом нижние пояса балок жесткости также расположены в горизонтальной плоскости. The walls of the stiffening beams in the variant of the cross section of the bridge (Fig. 2) are made with an inclination to the vertical by an angle equal to the angle of inclination to the vertical of the suspension of the cable trusses, and the upper belts of the stiffening beams are located in the horizontal plane. In this case, the lower belts of the stiffening beams are also located in the horizontal plane.

Стенки балок жесткости в варианте поперечного сечения моста по фиг. 3, выполнены с наклоном к вертикали на угол, равный углу наклона к вертикали подвесок тросовых ферм, верхние пояса балок жесткости расположены в горизонтальной плоскости, в то время, как нижние пояса балок жесткости выполнены перпендикулярно стенкам балок жесткости. The walls of the stiffeners in the cross-sectional variant of the bridge of FIG. 3 are made with an inclination to the vertical by an angle equal to the angle of inclination to the vertical of the suspension of the cable trusses, the upper belts of the stiffeners are horizontal, while the lower belts of the stiffeners are made perpendicular to the walls of the stiffeners.

Область применения предлагаемого изобретения висячие мосты с пролетами свыше 500 м. The scope of the invention, suspension bridges with spans over 500 m
