Detachable hoop type bridge supporting steel pipe connecting device and method

Abstract

The invention discloses a detachable hoop type bridge supporting steel pipe connecting device and method. The device comprises a profile steel assembly and a plurality of hoop connecting mechanisms which are distributed on the bridge supporting steel pipe assembly at equal intervals in the height direction of the bridge supporting steel pipe assembly, and the array structure of a plurality of hoops in the hoop connecting mechanisms is the same as the array structure of the bridge supporting steel pipes; the method comprises the steps that 1, the installation position of the hoop connecting mechanism is determined; 2, a 2 * 2 array type hoop connecting mechanism is installed; 3, an M * N array type hoop connecting mechanism is installed; 4, the hoops in the same horizontal cell are connected; 5, every two adjacent hoop connecting mechanisms are connected; and 6, the profile steel assembly and the hoop connecting mechanism are dismounted. The bridge supporting steel pipe assembly is supported through the in-layer profile steel assemblies used for connecting the multiple hoops in the hoop connecting mechanisms and the interlayer profile steel assemblies used for connecting every two adjacent hoop connecting mechanisms, and the machining quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a detachable hoop-type bridge support steel pipe connection device and method. Background technique [0002] In the process of bridge construction, steel pipes are commonly used as supporting members, and can be used as vertical steel pipe pile supports for supports and horizontal steel pipe inner supports for foundation pit support. When steel pipes are used as supports, it is necessary to connect the steel pipes. Most of the traditional methods are connected by welding. Welding panels on the side walls of steel pipes and welded section steel on the panels form a triangular connection of steel pipe piles. This method is used in construction. There are the following problems in the process: most of the panels and connecting steel are smaller blocks and shorter sections. With the change of steel pipe spacing, the panels and connecting steel are not easy to t...

AI Technical Summary

Problems solved by technology

When steel pipes are used as supports, it is necessary to connect the steel pipes. Most of the traditional methods are connected by welding. Welding panels on the side walls of steel pipes and welded section steel on the panels form a triangular connection of steel pipe piles. This method is used in construction. There are the following problems in the process: most of the panels and connecting steel are smaller blocks and shorter sections. With the change of steel pipe spacing, the panels and connecting steel are not easy to turn over, which is easy to cause waste of resources; the amount of welding work at the construction site is relatively large. Large, there are risks in progress control, and it is easy to cause environmental pollution; there are many vertical welding in welding, the welding quality is difficult to guarantee, and it is easy to cause quality defects in steel pipe connections; when steel pipes are designed to be connected in multiple directions, they must be welded at the same circumference of the steel pipe side wall , resulting in the concentration of thermal stress on the steel pipe or even burning the side wall, resulting in the concentration of stress on the steel pipe, which poses a safety risk
