MANUFACTURING METHODS FOR CONNECTION PART MINIMIZING THE REQUIRED AMOUNT OF STEEL PLATE AND, GIRDER HAVING THE CONNECTION PART MANUFACTURED BY THE SAME

摘要

In accordance with the present invention, a remaining part of a steel plate after making a vertical plate when a connection unit is manufactured by cutting a steel plate can be utilized as a structural material so that a required amount of the steel plate can be minimized. The present invention also obtains safety on fire by allowing a worker to easily manage construction and quality as an interference part of a fire resistive covering material of the connection unit and a concrete fire resistive covering section are clearly distinguished. The vertical plate protrudes to the upper side so that a resultant force with the concrete of a slab is improved and a horizontal shear capacity is improved.
