Description

Technical Field

[0001] The invention relates to the technical field of square steel connection, in particular to a subway trapezoidal sleeper connected square steel structure. Background Art

[0002] The subway trapezoidal sleeper is a green and environmentally friendly product used in the field of rail transportation to actively isolate vibrations and reduce noise. The subway trapezoidal sleeper consists of a unique frame structure consisting of a vibration-damping pad, two prestressed concrete longitudinal beams and connecting rods, and transverse and longitudinal limiters. While eliminating transverse prestress, it also simplifies the structure and manufacturing process.

[0003] The following problems exist: before installing the subway trapezoidal sleepers, the connected square steel structures need to be assembled. Since the common square steel structures are relatively simple, it is difficult to assemble the square steel structures. Not only do the heights of the two sets of square steel structures need to be aligned, but each set of square steel structures also needs to be fixed separately. This process not only wastes the workers' time, but also hinders the laying progress of the subway trapezoidal sleepers.

[0004] In view of this, research and improvement are conducted on the existing problems, and a subway trapezoidal sleeper connecting square steel structure is provided. By setting plug-in columns and through-holes, the two can be connected to each other, which mainly plays a limiting role, so that the process of high alignment of the two sets of square steel structures can be faster. By setting a first threaded collar and a second threaded collar, not only the first threaded column and the second threaded column can be installed, but both can also be fixed by the installation column at the same time. By setting a simple connection method between the installation column and the supporting steel cylinder, the disassembly and installation steps of the installation column are made more convenient and quick, and the space occupied by the installation column is also reduced. By setting the installation column, the first threaded collar and the second threaded collar can be fixed together at the same time, which plays the role of fixing the two sets of square steel structures. This process not only reduces the time wasted by workers, but also speeds up the laying progress of the subway trapezoidal sleepers. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Summary of the Invention
