Problems solved by technology

In addition to the above forms, in order to enhance the stiffness of the suspension bridge, double-chain suspension bridges and inclined suspension rod suspension bridges can also be used, but the structure is more complicated, and the cable bridge is often prone to collapse and is very unstable.

Embodiment

[0010] Embodiment: as shown in the accompanying drawing. A cable bridge capable of controlling the amplitude of sway, comprising a cable [1], a bridge deck [2], a concave protective groove [3] is set under the cable [1], and the cable [1] is placed in the protective groove , the height of the facade of the protective groove does not exceed the cable [1], the cable bridge swings when pedestrians walk, and the swing range of the cable is limited to the range of the protective groove.

[0011] A cable bridge capable of controlling the amplitude of swing, the concave groove [3] is made of cast-in-place concrete and steel bars.

[0012] A cable bridge capable of controlling the amplitude of sway, and the concave protective groove [3] can be used for emergency load bearing when the cable bridge fails or breaks.

[0013] The above-mentioned cable bridge capable of controlling the amplitude of swing can realize relatively stable security, and because the amplitude of swing of the cab...

Abstract

A cable bridge controllable in rocking range comprises cables (1) and a bridge floor (2). Concave protection grooves are formed below the cables (1) which are placed in the protection grooves. The height of vertical faces of the protection grooves is smaller than or equal to the height of the cables (1). The cable bridge rocks when passersby walk on the cable bridge, the rocking range of the cable bridge is limited within the range of the protection grooves, and the concave protection grooves (3) are formed by casting concrete and steel bars in place. The concave protection grooves (3) can be used for bearing in emergency under the condition that the cable bridge fails or breaks, and safety protection can be achieved in a relatively stable mode; because the rocking range of the cable bridge can be effectively controlled, the safety coefficient is increased.

Description

technical field [0001] The invention relates to a construction bridge. Background technique [0002] Nowadays, with the improvement of living standards, people begin to like to travel in mountains and rivers, and they generally encounter cable bridges. The bridge deck of the cable bridge generally does not have stiffening beams, so the stiffness is small. Under the action of vehicle load, the bridge deck will S-shaped deformation occurs with the change of the shape of the suspension cable, which is not good for driving, but its structure is simple, and it is generally used as a temporary bridge. The deck of the rigid suspension bridge is strengthened with stiffening beams, so the rigidity is relatively large. Stiffened beams can bear vertical loads with the overall structure of the bridge. In addition to the above forms, in order to enhance the stiffness of the suspension bridge, double-chain suspension bridges and inclined suspension rod suspension bridges can also be use...
