Description

Box lattice column

Technical Field

The utility model relates to a lattice column technical field especially relates to a box lattice column.

Background

The engineering often meets the bending component which is pressed and bent, and the characteristic of pressing rod and bending beam is required. The latticed column belongs to a common type in the bending members, the common latticed column comprises batten strip latticed columns and batten plate latticed columns, and the batten strip latticed columns and the batten plate latticed columns are both complex and easy to process severely influencing the stress performance of the structure, namely, the batten pieces are connected with the supporting columns through welding seams. Welding typically causes various degrees of weld cracking, lack of penetration, slag inclusions, porosity, and lack of weld appearance. Another type of lattice column used in relatively common use is a concrete filled steel tube lattice column, in which concrete is poured into a steel tube and tamped to increase the strength and rigidity of the steel tube to form a lattice column. Concrete filled steel tube lattice columns are often used for the construction of large public facilities, bridges and high-rise buildings, are rarely used for multi-storey residential buildings, and the construction of concrete parts is easily limited by seasons.

The Mao Jiemian of the lattice column is large, and the gyration radius is large, so that the length-to-fineness ratio of the lattice column is smaller under the condition of equal height with a solid-web column; the larger the hair section of the lattice column is designed, the higher the bending rigidity of the lattice column is, so that the lattice column has better bending resistance and smaller lateral deformation when being subjected to transverse load. In conventional lattice column design methods, the column limbs are usually arranged far from the inertia axis to obtain a larger moment of inertia, and therefore the profile sections are often thicker. Limited to the scarcity of land resources and the need for process arrangements, there is also a higher demand for the cross-section of the frame columns, i.e. the lattice columns are required to have a greater bearing capacity and a smaller cross-section.
