Description

Connecting Structure of steel column having internal diaphragm and connection plate

The present invention relates to a structure of a column joint having a vertical inner diaphragm and a connecting shroud function for the Cheolgolbo joint, and more particularly, when the column and the column in the Cheolgolbo joint are joined, the vertically adjacent end of the column is penetrated vertically at the same time. The vertical part is configured to serve as a vertical inner diaphragm inside the column, and at the same time, the connecting plate configured at right angles to one end of the inner vertical part is configured to protrude to the outside of the column, so that a separate bracket is not formed on the column. It relates to a column joint structure having both a vertical inner diaphragm and a connecting plate function for the Cheolgolbo joint to provide a joint surface to which the Cheolgolbo is joined.

In general, in the construction of steel structures in architecture or civil engineering works, hollow steel pipe columns with excellent cross-sectional performance such as square steel pipes and P-shaped steel pipes are used for the columns. Attach and fasten with bolts.

However, at the time of joining such columns, the cheolgolbo should be joined to the connecting part between the columns, but a separate bracket should be installed on the column for joining the cheolgolbo and a connecting plate should be added to attach it. The diaphragm required to connect to Cheolgolbo must be installed, but the internal horizontal diaphragm requires precision to be installed at the same location as the junction of Cheolgolbo. There was a problem that the horizontal diaphragm did not act as a reinforcement for connecting Cheolgolbo.

As a technology that is the background of the present invention, there is Patent Publication No. 1998-021969 "Unit Columns and Connections for Steel Structures" (Patent Document 1). In the background art, 'in forming the column body 1 of a steel structure made of a round or square steel pipe, a high-strength steel plate is formed perpendicularly to a +-shape, and a plurality of fastening holes 4 are drilled at the ends of the four sides of the steel plate. The +-shaped connection part 3 is formed, and the symmetrical parts are cut and processed so that the ''+-shaped connection part 3 can be inserted at the top and bottom of the unit column 2 to form the cutout 5. Thus, by inserting the +-shaped connection part 3 into the cutout 5, and welding the inside and outside ground planes to form the pillar body 1, we propose a 'unit column and connection part for a steel structure structure' , By connecting the columns and crossbeams precisely and quickly at the site of the steel structure, it reduces the assembly man-hours at the site and promotes the prevention of safety accidents during assembly work, as well as shortening the construction period and reducing the construction cost.

However, in the background art, it is difficult to reinforce the joint between columns, and when concrete is poured inside the column, it is difficult to control the out-of-plane deformation at the joint due to the pouring pressure. there was.
