Abstract

The invention discloses a pipe type bridge floor flat pull cable bridge which comprises a group of steel cables (1) connected with two shores. A left end steel pipe bridge floor assembly (2), a group of intermediate steel pipe bridge floor assemblies (3) and a right end steel pipe bridge floor assembly (4) are sequentially arranged on the steel cables from left to right. The bottom of each steel pipe bridge floor assembly is provided with a group of screws (5), and the screws (5) are connected with the steel cables through connecting plates (6) and nuts (7). According to the pipe type bridge floor flat pull cable bridge, the problems that an existing wood structure bridge floor plate is poor in durability and needs to be replaced frequently are solved, and the maintenance workload and cost are reduced. The problems of steel cable abrasion caused by the bridge floor plate and steel wire bending and damage are solved effectively through arc-shaped gaskets, and the service life of the bridge is prolonged. The integrity of the bridge floor plate and the steel cables is enhanced through connecting components, and running stability and safety are improved. The bridge floor plate can adapt to bridge floor deformation requirements well through clamping pins. The pipe type bridge floor flat pull cable bridge is simple in structure and convenient to install, and the bridge floor plate can be reused.

Description

technical field

[0001] The invention relates to a flat-stayed cable bridge with a tubular deck, belonging to the technical field of bridge structures. Background technique

[0002] Flat-stayed cable bridge is a flexible bridge system with steel cables as the force-bearing structure, the bridge deck is directly laid on the steel cables, and the line shape of the bridge deck is basically consistent with the line shape of the steel cables. Therefore, in order to adapt to the deformation of the cables, the deck of the cable-stayed bridge is usually spliced ​​longitudinally by smaller decks. The bridge deck of the existing flat-stayed cable bridge generally adopts a wooden structure, for example, the "deck structure of a flat-stayed cable bridge" disclosed by the applicant in the patent document with publication number 202989775U. Due to the low strength of the wooden structure, a thicker bridge deck is required to bear the larger vehicle load, so the requirements for the materi...

Examples

Embodiment 1

[0025] This example Figure 1 to Figure 8As shown, it consists of a number of standard steel pipes and special-shaped steel pipes juxtaposed. The standard steel pipe is used as the upper steel pipe 8, and the special-shaped steel pipe is used as the lower steel pipe 9. A number of standard steel pipes are welded side by side to form a plane as the bridge deck, that is, the centers of all standard steel pipes are located on a straight line when viewed from the cross section. The special-shaped steel pipe is connected with the steel cable 1. There are two types of special-shaped steel pipes, one is located on the edge of the component and needs to be connected with adjacent components, such as the protruding steel tube 17 in the lower layer and the extra steel tube 18 in the lower layer, and the other is located in the middle of the component and does not need to be connected to adjacent components The rest of the lower steel pipes 9 connected by the components. All the other...

Embodiment 2

[0028] This example Figure 1 to Figure 8 As shown, all the staples 11 in the embodiment are replaced with hooks 14, and all the staple holes 12 are replaced with hook holes 15 to form the second embodiment. Since the shape of the hook 14 is different from that of the staple 11, the shape of the corresponding hook hole 15 should also correspond to it.

Embodiment 3

[0030] The connector in embodiment 1 is a staple 11 , and the connector in embodiment 2 is a hook 14 . In practice, the two connectors can also be used at the same time, which can be used as embodiment 3.
