Description

Technical Field

[0001] The utility model relates to the technical field of lattice columns, in particular to a lattice column structure. Background Art

[0002] In the process of underground engineering construction, the construction quality and construction safety of deep foundation pits are particularly important. The use of lattice column support in deep foundation pit construction is a common support construction method. Lattice columns are used as compression-bending members, mostly used for factory frame columns and independent columns. The cross-section is generally designed with steel sections or steel plates in a biaxially symmetrical or uniaxially symmetrical cross-section. Lattice system components are composed of limbs and tie materials. The limbs mainly bear axial forces, and the tie materials mainly resist lateral forces (relative to the axial direction of the limbs). The tie materials of lattice columns mainly include tie bars and tie plates.

[0003] The existing lattice column tie materials mainly include tie bars and tie plates. The structural feature of the lattice column is that the material area is arranged far away from the inertia axis, which can ensure the enhanced bending resistance of the component under the same axial resistance conditions and save materials. In the past construction process, due to the lack of good protection of the lattice column welding, the surface was seriously contaminated during the pouring of cast-in-place pile concrete and the backfilling of empty holes, affecting the subsequent construction quality and progress. At the same time, it takes a lot of manpower, material resources and financial resources to clean up the surface pollution. Utility Model Content
