Assembled steel pipe upright post system

Abstract

The invention discloses an assembled steel pipe upright post system. The assembled steel pipe upright post system comprises a plurality of upright post segments which are mutually connected in the horizontal direction and / or the vertical direction respectively, each upright post segment comprises an upright post steel pipe, joints for connecting with bolts of the peripheral upright post segments in the horizontal direction are arranged on the outer surfaces of the upright post steel pipes and end part flange plates for connecting with the bolts of the upper and the lower upright post segments in the vertical direction are arranged at two ends; and the plurality of the upright post segments are connected into a whole through at least one type of linking rods, node plates, the joints or the end part flange plates. The assembled steel pipe upright post system has the advantages of great carrying capacity, reliability in connection, quickness and convenience in mounting and detachment and high universality, and can be used repeatedly, be combined and extended arbitrarily in the plane and the elevation and be economic and practical.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to an assembled steel pipe column system. Background technique [0002] With the development of bridge construction in our country towards the direction of large span and heavy load, the vertical loads borne by large temporary column structures such as temporary buttresses, support columns, buckle towers, and cable suspension towers used in bridge construction are also increasing. getting bigger. In the construction process of bridges, in order to assemble temporary bridge piers, large towers and large supports, assembled columns are often used. Traditional assembled column structures, such as construction steel pipe scaffolding, universal rods, and highway assembled steel beam trusses (Bailey beams) are all section steel or small steel pipes with a small bearing capacity, which is far from meeting the requirements of bridge construction. need. At present, engineering constructi...

AI Technical Summary

Problems solved by technology

These steel pipe column structures are basically manufactured individually according to the needs of specific projects, rather than standardized parts. The connection between steel pipes is also mostly welded structure, which is time-consuming and labor-intensive to process and difficult to install on site.

After use, this non-standard welded structure can only be dismantled destructively. During the dismantling process, the steel pipe will be seriously damaged and the loss will be large. The dismantling construction is inconvenient, and the dismantled structure cannot be directly used in other projects and needs to be rebuilt.

To sum up, the traditional column structure generally has the defects of small bearing capacity, unreliable connection, inconvenient installation and removal, poor versatility, low reuse rate, and poor economical practicability.
