Pillar-to-pillar connecting joint

Abstract

The invention provides a pillar-to-pillar connecting joint. The connecting joint comprises a first steel pillar, a second steel pillar, a connector, ring-grooved rivets and connecting plates; the first steel pillar, the second steel pillar and the connector are in a shape of a hollow pillar and are structurally identical; the first steel pillar and the second steel pillar are respectively sleevedat two ends of the connector; the outer side walls of the connector are attached to the inner side walls of the first steel pillar and the second steel pillar; the end parts of the first steel pillarand the second steel pillar are in contact with each other, and a plurality of the connecting plates are circumferentially arranged at the contact position; a plurality of bolt holes are formed in thefirst steel pillar, the second steel pillar, the connecting plates and the connector; and the steel pillars, the connecting plates and the connector are connected together via the ring-grooved rivets. According to the connecting joint, the bolt holes are formed in the end of sealed-section steel pillars, and the steel pillars, the connecting plates and the connector are connected together via thering-grooved rivets; the joint can realize reliable connection, and the force transmission path is explicit; and the defects of cracks, air holes, slag inclusion, incomplete fusion and incomplete welding which may occur in a welding process are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a column splicing node. Background technique [0002] Most of the column connection forms are flange connection, welding and bolt connection. Flange connection is widely used in industrial buildings because of the protruding column section, but less in the field of construction engineering. Welding process There is always welding residual stress after welding. At the same time, due to the rapid cooling of the heat-affected zone of the welded parts, under the condition of high carbon content, it is easy to produce quenched martensite and cracks; the control is not in place during the welding process, Defects such as pores, slag inclusions, lack of fusion, and lack of penetration are prone to occur. Moreover, the on-site welding takes a long time and the work efficiency is low. The bolted connection often requires a large labor cost during construction, and for colum...

Problems solved by technology

Flange connection is widely used in industrial buildings because of the problem of protruding column sections, but less in the field of construction engineering

Welding process There is always welding residual stress after welding. At the same time, due to the rapid cooling of the heat-affected zone of the welded parts, under the condition of high carbon content, it is easy to produce quenched martensite and cracks; the control is not in place during the welding process, Pores, slag inclusions, lack of fusion, lack of penetration and other defects are prone to occur

Moreover, on-site welding takes a long time and the work efficiency is low

The bolted connection often requires a large labor cost during construction, and for columns with closed sections, due to the technical problems of the bolts, it is difficult to apply bolted connections to column-to-column connections with closed sections.
