Abstract

The invention discloses a Hooke bridge mainly composed of a main beam, rigid inclined rods, balance rods, web members and stand columns. The two ends of the main beam are connected with the stand columns. The rigid inclined rods comprise a rigid outer inclined rod and a rigid inner inclined rod; the bottom ends of the rigid outer inclined rods are connected with the stand columns, the middles of the rigid outer inclined rods are connected with the main beam, and the balance rod is arranged between the top ends of the rigid outer inclined rods. The top ends of the rigid inner inclined rods are connected to the joint of the rigid outer inclined rods and the balance rods, and the bottom ends of the rigid inner inclined rods are connected with the main beam; the web members are arranged between the main beam and the balance rods to form a middle double-layer truss; the web members are arranged among the main beam, the rigid inclined rods and the stand columns to form a triangular truss; the middle double-layer truss and the triangular truss are connected through a truss type structure. The calculation span of the main beam is obviously reduced, the bending resistance of the middle of the main beam is improved, the internal force and deformation of the middle of the main beam are reduced, the bearing capacity of the inclined leg is improved, and the integrity of the structure is enhanced.

Description

technical field [0001] The invention belongs to truss bridges, in particular to a Hooker bridge. Background technique [0002] A truss bridge is a bridge with truss as the main load-bearing member of the upper structure. A truss bridge is generally composed of a main bridge frame, upper and lower horizontal longitudinal connection systems, bridge portal frames, intermediate cross braces and bridge deck systems. In the truss, the chord is the member that makes up the periphery of the truss, including the upper chord and the lower chord. The member connecting the upper and lower chords is called the web, which is divided into oblique and vertical according to the direction of the web. The plane where the chord and web are located is called the main truss plane. [0003] Since the end of the nineteenth century, the definite force and structural analysis theories of beams have been successively established, which has promoted the development of truss bridges, and various forms ...
