Description

Steel pipe column connection structure{CONNECTING STRUCTURE FOR COLUMNS}

The present invention relates to a steel pipe column connection structure, and more particularly, to a connection structure between a column and a beam that can be easily assembled and has excellent strength resistance compared to the prior art when connecting a column and a beam.

A lot of columns and beams are needed when constructing a building. Usually the pillars and beams are made of metal. For example, the pillar may be in the form of a square metal pipe with an empty inside, and the beam may be an H-shaped steel.

After connecting the pillars and beams to each other to create the framework of the building, the building can be constructed through it.

As such, many pillars and beams are used when constructing buildings, and since they must be connected, various technologies for so-called cores for connecting them are known, and some technologies have been applied and registered by the present applicant.

On the other hand, before connecting the beams when constructing a building, first of all, the columns, in particular, several closed-section steel pipe columns, which are closed sections, must be connected to each other. This is because steel pipe columns are manufactured in unit lengths, so they must be connected to form one body.

If you want to connect a pair of steel pipe columns, that is, the upper column and the lower column, you may consider connecting them by attaching a separate intermediate column.

However, considering the fact that this method requires more intermediate pillars, which causes cost increase, and that the construction period may be delayed due to an increase in the number of work hours, the need for a new concept of steel pipe column connection structure that is not known before. This will emerge.
