Description

Technical Field

[0001] This utility model belongs to the technical field of box-type column connection structure, specifically a box-type column connection structure with bending resistance function. Background Technology

[0002] A box-shaped column is named for its shape, which resembles a large iron box. It is typically used as a beam or column in steel structures.

[0003] A search revealed that patent CN215053889U discloses a connection structure between a box column and a box beam, including a box column, a corbel beam, a box beam, and a through flange plate. One end of the corbel beam is fixedly connected to the side wall of the box column, and the other end of the corbel beam is fixedly connected to the box beam. A common connecting slot is provided on the opposite side walls of the corbel beam and the box beam. The through flange plate passes through and is fixed to the corbel beam and the box beam via the connecting slot. By creating a first slot and a second slot on opposite sides of the corbel beam and the box beam at their connection point, and installing the through flange plate in the first and second slots, stress is dispersed from more points, avoiding stress concentration at the joint between the corbel beam and the box beam. Furthermore, for box columns and box beams with large cross-sections, the connection method of inserting and then welding is relatively simple, reduces construction difficulty, and reasonably shortens the work cycle.

[0004] In existing box-type column connection structures, two sets of box-type columns are typically welded together using connecting lugs. However, the box-type columns are prone to shifting after welding, which reduces the structural strength of the box-type columns. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a box-type column connection structure with bending resistance, thereby achieving the bending resistance function of the box-type column connection structure.

[0007] Based on the above structure, four sets of connecting ears are welded to the top of the first box column and the bottom of the second box column, respectively. Then, the two sets of bonding plates are fixedly connected by fastening bolts. By setting right-angled trapezoidal support plates, the support area of ​​the first and second box columns is increased, improving the stability of the connection between the first and second box columns. At the same time, by setting triangular corner plates, the connection strength between the partition and the first box column is improved, preventing the first and second box columns from deflecting after welding, thus realizing the bending resistance function of the box columns.

By setting the right trapezoidal support plate, it is beneficial to increase the support area of ​​the first box column and the second box column, and improve the stability of the connection between the first box column and the second box column.

[0011] Preferably, four sets of corner plates are provided, and the four sets of corner plates correspond one-to-one with four sets of connecting ears. The corner plates are triangular in shape. By setting triangular corner plates, it is beneficial to improve the connection strength between the partition and the first box column and avoid deformation of the first box column.

By setting the connecting base plate and wing plate in a "T" shape, it is convenient to install the connecting base plate to the outer wall of the second box column by fastening bolts. Then, the side plate is installed on the side wall of the I-beam by fastening bolts. At the same time, the wing plate is installed at the upper and lower ends of the I-beam by fastening bolts.

[0013] Preferably, the support plate is in the shape of a right triangle. By setting the support plate in the shape of a right triangle, it is beneficial to support the flange, improve the stability of the I-beam connection, and prevent the I-beam from deforming.
