Background

Steel structures are structures composed of steel materials and are one of the main building structure types. Because of its light dead weight, and construction is simple and convenient, widely apply to fields such as large-scale factory building, venue, superelevation layer. But the steel construction can produce great deformation because of expend with heat and contract with cold's reason when temperature variation, consequently need set up the telescopic device in the junction of steel construction to satisfy the deformation demand of steel construction, but current scalable steel construction connecting piece can not cushion, does not have the resilience function moreover, leads to can not the self-recovery original state after the external force that the connecting piece receives disappears, leads to the steel construction junction to produce the problem such as gap, influences the long-term use of steel construction. To this end, we propose a new type of telescopic steel structural connection to solve such problems.
