A steel bar structure for viaduct construction and its fastening method

Abstract

The invention relates to the technical field of viaduct construction, and particularly discloses a reinforced bar structure for viaduct construction. The reinforced bar structure comprises main reinforced bars and an auxiliary reinforced bar, wherein the main reinforced bars are connected through coupling mechanisms; the auxiliary reinforced bar is connected to the outer sides of the main reinforced bars in a sleeving manner; each coupling mechanism comprises arc-shaped blocks, external thread plates, arc-shaped plug pins, fastening nuts and a base. The invention further discloses a fastening method of the reinforced bar structure for the viaduct construction. The method comprises steps as follows: 1), end parts of the main reinforced bars 1 required to be connected are grounded by abrasive paper; 2), the arc-shaped blocks 5 are connected to the main reinforced bars 1 in a sleeving manner end to end; 3), the base 10 is arranged between end parts of two main reinforced bars 1 required to be connected. The reinforced bar structure is reasonable in structure, has strong actual operability, is simple and convenient to operate, can be prevented from accidental damage and prolongs the service life of a viaduct, and more convenience and effective quality in use are realized when the main reinforced bars are connected.

Description

technical field [0001] The invention relates to the technical field of viaduct construction, in particular to a steel bar structure for viaduct construction and a fastening method thereof. Background technique [0002] During the construction of the viaduct, steel bars need to be used as the skeleton of the concrete. Most of the steel bar structures in the prior art are placed in advance before concrete pouring. However, the steel bar structures in the prior art are composed of main steel bars As the main body, the auxiliary steel bar is used as a bracket to support the use position of the main steel bar. Traditionally, the iron wire is used to achieve the fastening effect between the auxiliary steel bar and the main steel bar. However, this fixing effect will cause the steel structure to be transported or received by the concrete. The momentary loosening occurs, which leads to damage to the steel structure, which greatly affects the quality of the viaduct construction, and ...

[0002] During the construction of the viaduct, steel bars need to be used as the skeleton of the concrete. Most of the steel bar structures in the prior art are placed in advance before concrete pouring. However, the steel bar structures in the prior art are composed of main steel bars As the main body, the auxiliary steel bar is used as a bracket to support the use position of the main steel bar. Traditionally, the iron wire is used to achieve the fastening effect between the auxiliary steel bar and the main steel bar. However, this fixing effect will cause the steel structure to be transported or received by the concrete. The momentary loosening occurs, which leads to damage to the steel structure, which greatly affects the quality of the viaduct construction, and then affects the service life of the viaduct. It needs to be greatly improved, and the main steel bar is an individual with a certain length. In use, it is often necessary to use a coupling structure to connect the corresponding main steel bars to each other. There are certain problems in the connection structure in the prior art, for example: the use effect is poor, it is easy to loosen, and the installation and use are more troublesome.
