Description

Technical Field

[0001] The present invention relates to the technical field of beam-column construction, and particularly relates to a construction method for the intersection position of a main structure and a lattice column. Background Art

[0002] At present, most projects are deep foundation pits. To ensure the safety of the foundation pit, a large number of support beams and support lattice columns are arranged. In order to save construction costs, engineering piles are considered when arranging support lattice columns. Since most engineering piles are close to structural columns, there will be a situation where the lattice column penetrates the beam when using engineering piles as support column piles. The conventional treatment method is to disconnect the position where the lattice column penetrates the beam, and use materials such as steel pipes or disc buckle scaffolds to jack up the beam. This method has great limitations. The formwork cannot be removed for a long time, which affects the use of the basement space. The long-term jacking of the formwork will generate high material rental fees, and there is a risk of downward deflection of the beam, which is not conducive to the structural force. Summary of the Invention

[0003] In view of the above situation, the present invention provides a construction method for the intersection position of a main structure and a lattice column, which solves the technical problem that the erection of supports in traditional construction affects the use of underground space.
