Description

Technical Field

[0001] The utility model provides a steel structure column connection structure, belonging to the technical field of steel structure buildings. Background Art

[0002] Steel structural columns are columnar load-bearing structural elements constructed with steel as the main material in construction projects. Steel structural columns are widely used in the field of modern construction due to their excellent mechanical properties, high degree of industrialized production, fast construction speed, and green environmental protection.

[0003] Patent No.: CN207794434U; discloses a steel structure column and a connection structure of a steel structure column, wherein the steel structure column includes a column body, the column body is a rectangular structure composed of steel plates, a reinforcing plate is arranged inside the column, and the reinforcing plate is a V-shaped structure; a convex lap portion is arranged on the lower side of the column body, and lead plates are arranged at the upper and lower ends around the column body, the lead plates are welded to the column body, and a plurality of screw holes are arranged on the lead plates.

[0004] The upper and lower columns approved by the above patent are connected together by overlapping parts, lead-out plates and connecting parts, which makes it easy to install and improves the stability of the steel structure column. The steel structure column is not easy to deform and break at the connection. However, the steel structure columns are heavy and need to be hoisted by a crane. The crane hoisting will cause the steel structure column to rotate and tilt slightly due to its hook and the hoisting position of the steel structure column. When the lower column is installed in the foundation pit, it is easy to adjust because it is in the foundation pit. When the upper column is connected to the lower column, the upper end of the lower column is higher, so the adjustment remains unchanged. Therefore, workers need to cooperate with the crane for a long time to adjust the overlapping part to insert the upper end of the lower column. Utility Model Content

[0007] As an improvement, the lower ends of the two reinforcing plates are flush with the lower ends of the lower column and the upper column, respectively, and the upper ends do not exceed the upper ends of the lower column and the upper column, respectively;

[0008] As an improvement, the length of the protruding portion of the guide block is less than the distance from the upper end of the reinforcing plate to the upper end of the lower column;

[0009] As an improvement, the cross section of the guide block is the same as the cross section of the portion of the lower column that is not provided with the reinforcement plate;

[0010] As an improvement, a plurality of corresponding through holes are provided on the ear plate;

[0011] As an improvement, the connecting plate is provided with a plurality of through holes coaxial with the ear plate;

[0012] As an improvement, the diameter of the through hole is larger than the diameter of the screw rod portion of the bolt, and smaller than the diameter of the bolt head and the nut portion.

[0013] Beneficial effects of the utility model:

[0014] Symmetrical ear plates are provided and hoisting holes are provided on the ear plates, so that when a crane hoists the upper column and the lower column, a sling is used to pass through the symmetrical hoisting holes, and then when the upper column or the lower column is lifted, the upper column or the lower column can be in a vertical state under the action of gravity. By providing a guide block, when the upper column is installed to the lower column, it is only necessary to make the end of the guide block be in the lower column, and the guide block can guide the upper column and align the outer edges of the upper column and the lower column.
