Description

Technical Field

[0001] The utility model relates to a connection structure, in particular to a connection structure at the bottom of a steel pipe column. Background Art

[0002] The steel pipe column is a common support structure in modern buildings. It is made of steel pipe and has the advantages of high strength, stability and durability. In order to prevent the steel pipe from rusting and corroding, hot-dip galvanizing treatment is usually adopted to extend the service life. The connection method of the steel pipe column is also very flexible. It can be connected by bolts or directly welded and fixed, and is widely used in the fields of buildings, bridges, roads, etc.

[0003] The patent with the patent authorization announcement number CN205025077U discloses a fastener-type steel pipe column with a connecting plate, including a column. A plate is provided at the bottom of the column, and the column and the plate are integrated. One end of the column is perpendicularly welded to the plate, and the center of the column coincides with the center of the plate. Although the above patent can avoid the situation of no plate under the steel pipe column by setting the plate and ensure the uniform force on the foundation, there are still deficiencies in actual use. For example, when the steel pipe column is placed on the ground, the contact weight between the steel pipe column and the plate and the ground is not large, so the stability of the steel pipe column is not high and it is easy to be displaced or toppled by external factors.

[0004] Therefore, there is a particular need for a connection structure at the bottom of a steel pipe column to solve the problems existing in the prior art. Content of the Utility Model

[0005] In order to overcome the shortcomings that the contact weight between the steel pipe column and the plate of the existing patent and the ground is not large, so the stability of the steel pipe column is not high and it is easy to be displaced or toppled by external factors, the utility model provides a connection structure at the bottom of a steel pipe column.

[0006] The utility model is achieved through the following technical means: A connection structure at the bottom of a steel pipe column includes a base, a steel pipe column and bolts. The steel pipe column is slidably connected inside the base. Fixing holes distributed circumferentially are opened at the lower part of the base, and bolts are threadedly connected inside the fixing holes. A cover plate is further included. A filling cavity is opened inside the base, and a cover plate for sealing is installed at the upper part of the base, and the cover plate covers the entrance of the filling cavity.

[0007] In addition, particularly preferably, a sleeve plate and support legs are further included. Two sleeve plates are placed on the cover plate, and the two sleeve plates are connected by bolts to form a sleeve ring to sleeve the lower end of the steel pipe column, and symmetrically distributed support legs are installed outside the sleeve plate.

[0008] In addition, particularly preferably, the bottom surface of the support leg is on the same horizontal plane as the ground surface of the base, and mounting holes are provided on the support leg.

[0009] In addition, it is particularly preferred that a connecting plate and a damper are further included, wherein the connecting plate is fixedly connected to the lower inner portion of the base, and a plurality of dampers distributed in a circular path are arranged between the steel pipe column and the connecting plate.

[0010] In addition, it is particularly preferred that nuts are further included, and the lower part of the base is rotatably connected to a plurality of nuts distributed along the circumferential direction, and the nuts are threadedly connected to the corresponding bolts.

[0011] In addition, it is particularly preferred that ribs are further included, and the lower part of the base is fixedly connected with ribs evenly spaced and distributed for reinforcement.

[0012] From the above description of the structure of the utility model, it can be seen that the design starting point, concept and advantages of the utility model are: 1. By setting a filling cavity and a cover plate, the cover plate is removed from the base to open the filling cavity, and then filling materials such as cement or concrete are poured into the filling cavity, thereby increasing the contact weight between the base and the ground, improving the stability of the steel pipe column, and effectively solving the problem that the existing steel pipe column is easily affected by external factors and causes displacement or tipping.

[0013] 2. By setting the sleeve and support feet, install the sleeve back on the steel pipe column, and then use the mounting parts to fix the support legs on the ground. The support legs increase the contact area between the base and the ground, further improving the stability of the steel pipe column.

[0014] 3. By setting the damper, when the steel pipe column moves downward due to the impact of falling foreign objects, the damper plays a buffering role, thereby reducing the impact force on the steel pipe column. BRIEF DESCRIPTION OF THE DRAWINGS
