Cylinder cylinder beam joint structure null of RC beam S

摘要

PURPOSE: To simplify machining and assembling of a form of a column junction by burying a beam joint hardware into the concrete of the column junction and, at the same time, making flush the beam joint end with a column side to joint it with a structural steel beam. ;CONSTITUTION: Beam joint hardware 2 having flat plate-like beam junctions 2b in the horizontal direction to the front ends of anchor sections 2a in a plane cross shape, etc., are formed. After that, when a reinforced concrete column 1 is formed, two up and down hardwares 2 are buried into the concrete of a column junction. Then, in the case they are buried, an interval between up and down hardwares 2 is made to correspond to a level between up and down flanges 3a of a structural steel beam 3 and, at the same time, the front ends of the junctions 2b are flush with the surface of a column 1. The flanges 3a are connected to the junctions 2b by means of welding, etc. In addition, mortar, etc., are filled into thermal influence protecting recess sections 4 provided in advance. According to the constitution, machining and assembling of a column form can be simplified, and execution efficiency of the column can be promoted by using a slip-form method.;COPYRIGHT: (C)1993,JPO&Japio
