[0002] Nowadays, with the rapid development of urbanization, subways have become an important means of transportation for residents in medium and large cities, and have also become an important engineering project for the utilization and construction of urban underground space. Open excavation is a more commonly used construction method for domestic subway construction. The foundation pit support mostly adopts the method of retaining structure + internal support. When the span of the open excavation is large, one or more lattice columns are added at the mid-span for temporary vertical support. The lattice columns will be removed after the station structure construction is completed. Therefore, for ultra-wide open excavation stations with a large number of lattice columns in the foundation pit, it is particularly important to complete the lattice column removal work safely, conveniently and efficiently.

[0003] Traditional lattice column dismantling methods usually use gas cutting or plasma cutting. This type of dismantling method involves hot work, which has a high safety risk and has high requirements for cutting workers, who must be certified to work. At the same time, high-temperature cutting causes serious blackening of the critical surface of concrete, which does not meet the requirements of green construction energy conservation and emission reduction, and affects the strength of the concrete structure and the aesthetics of the outer surface. The lattice columns cannot be recycled after they are dismantled.

[0004] Therefore, in view of the above problems, a cutting-free lattice column connection structure is proposed to solve the above problems. Utility Model Content

[0025] By providing the clamping pieces and the connecting bolts 4, the connection of the connecting structure is facilitated, and the lattice column dismantling work can be completed safely and quickly without cutting, thereby ensuring the integrity of the lattice column standard section 1, realizing the recycling of the main part of the lattice column, and further achieving the goal of green construction, energy saving and emission reduction.

[0026] In this embodiment, the hook 5 is in a "C" shape, and the opening of the hook 5 is facing the direction close to the standard section 1. The blocking rod 6 includes a vertical rod 8 and a cross rod 9. The cross rod 9 is horizontally arranged. The cross rod 9 is connected to the flange 2 through a spring 10, and the cross rod 9 is horizontally connected to the side of the vertical rod 8 away from the hook 5.
