Large steel pipe truss used for cover beam cast-in-place construction and construction method

Abstract

The invention relates to a large steel pipe truss used for cover beam cast-in-place construction and a construction method. Two pieces of truss bodies are located on the two sides of a pier upright column and fixed to the pier upright column, and each truss body is composed of an upright rod, an upper chord, a lower chord, a large oblique rod and a web rod. Each upright rod is composed of an upperupright rod and a lower upright rod. The lower upright rod is a double-spliced steel pipe placed on a bearing table surface. The upper end of the double-spliced steel pipe is fixedly connected with the corresponding upper upright rod through the corresponding lower chord. The top of the upper upright rod is fixedly connected with the corresponding upper chord. Each large oblique rod is connectedbetween the corresponding upper chord and the corresponding lower chord rod. Each web rod is connected between the corresponding upper chord and the corresponding large oblique rod. By means of the large steel pipe truss, the technical problems that a cover beam is located in the edge of a river channel, one side of the cover beam is close to water, there is height difference between a road and the bearing table surface, a cover beam K33 is located in the center of the river channel, a landing type full framing cannot be built up are solved, a bearing table is fully used as the supporting surface, and the self-made large steel pipe truss and the construction method are adopted; and in addition, the truss can also be used for a standard cover beam on a general road section, and two side spaces of the truss can meet traffic demands.

Description

technical field [0001] The invention relates to a building cover beam, in particular to a large steel pipe truss used for a cover beam, and belongs to the technical field of large steel pipe trusses. Background technique [0002] A certain project is located on the current East Outer Ring Road, the foundation is in good condition, and the cover beams are cast-in-place by bracket method. After comprehensive consideration of traffic, rivers, green belts and other influencing factors, the design of the cover beam support of the project will be a large steel pipe truss. [0003] Among them, No. K23, K24, K32, and K34 cover beams are located on the side of the river, facing the water on one side, and there is a height difference between the road and the platform. The bearing platform is used as the supporting surface, and the self-made large steel pipe truss method is used for construction. Of course, this truss can also be used for standard cover beams on general road sections...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the technical problem that the floor-to-ceiling full hall support cannot be erected when the cover beam is located in the center of the river, and provides a large steel pipe truss and construction method for the cast-in-place construction of the cover beam
