Problems solved by technology

Since the longitudinal displacement of the main beam is basically unchanged under the action of temperature and the bending stiffness of the column is much smaller than the axial stiffness of the main beam, the method of reducing the stress at the end of the column by increasing the bending stiffness of the column is less effective

Embodiment Construction

[0053] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as figure 1 It is the facade layout of the hinged column top-supporting arch bridge, in which the upper and lower ends of the column 4 are hinged with the main beam 2 and the main arch 3 .

[0055] A kind of articulated column top-supporting arch bridge and its construction method of the present invention will be further described in conjunction with a certain engineering case below.

[0056] A kind of articulated column up-supported arch bridge and its construction method, such as Figure 2 to Figure 9 As shown, it specifically includes the following construction steps:

[0057] Step 1. Pouring abutments and abutments

[0058] Pour the abutment and abutment 1 according to the conventional method;

[0059] Step 2. Erection of the main arch

[0060] 1) When erecting the main a...

Abstract

The invention discloses a stand column applied to a deck type arch bridge. The upper end and the lower end of the stand column are connected with a main beam and a main arch in a hinged mode. The invention further discloses a construction method of the stand column applied to the deck type arch bridge. The construction method comprises the following steps that 1, pouring the bridge abutment and the arch support; 2, erecting a main arch; 3, mounting a stand column; 4, installing a main beam; and 5, installing the stand column sealing plate. The stress concentration at the end of the stand column can be eliminated, the stand column structure is simplified, the manufacturing cost is saved, a structural stress system is clearer, the appearance is more attractive, and the node durability is better.

Description

technical field [0001] The invention relates to a column structure and a construction method thereof, in particular to a column applied to an overhead arch bridge and a construction method thereof, and belongs to the technical field of bridge construction. Background technique [0002] The upward-supported arch bridge has a series of advantages such as beautiful shape, high structural rigidity, strong bearing capacity, and low building height, and is especially suitable for bridges across rivers and ditches in some small and medium-sized cities. For the upward-supported arch bridge, it is mainly composed of four parts: abutments on both sides, main girders, main arches and vertical columns. Because the main arch is constrained by the abutment, the main girder will have a horizontal displacement relative to the main arch under temperature load, resulting in a large bending moment and shear force on the column, which will affect the safety and service life of the bridge.
