Description

A beam-column steel ring-slab joint structure for vertical drainage and its method

technical field

The invention belongs to the field of drainage pipes, in particular to a beam-column steel ring-plate joint structure and its method for vertical drainage.

Background technique

At present, the drainage of the roof generally adopts the following method, that is, a drainage ditch is arranged on the roof to collect the rainwater on the roof, and the water is diverted to the ground through vertical water pipes. If the vertical water pipe is arranged on the outside of the building, it is very unsightly; if the vertical water pipe is arranged on the inside of the building, for aesthetic considerations, it is generally close to the column edge and wrapped with decoration materials. However, in steel structures, steel ring plates are often installed at the beam-column joints with large spans. The steel ring plates will protrude a certain distance outside the column, causing the vertical drain pipe to collide with it. If the drain pipe directly passes through the steel ring plate, It will lead to structural safety problems. If the position of the drain pipe is moved to the outside of the steel ring plate, it will be very unsightly and affect the indoor space. See Figure 1 and Figure 2 for details.
