Abstract: PURPOSE: A method for connecting and joining structural insulating walls is provided to save energy, facilitate construction, improve air-tightness, and minimize heat loss. CONSTITUTION: A method for connecting and joining structural insulating walls comprises following steps. A first joint member(105-1) having a concavo-convex shape is coupled with an insulating wall(103). The opposite surface of the concavo-convex surface of a second joint member(105-2) is coupled with the opposite surface of the concavo-convex surface of the first joint member. The first and second joint members fix each other using a C-shaped clamp(108) as a first fixing unit. Both insulating walls are fixed using a C-shaped clamp(109) as a second fixing unit. A gasket is installed in the contact section between the joint members and the insulating material.

Abstract: PURPOSE: A method for estimating the long-term clamping force of the existing high tension bolt in consideration of the loss of a clamping force resulting from the creep on a coated surface is provided to accurately predict the state of a high tension bolt applied to friction welding of a steel structure so as to effectively determine standards on safety inspection, diagnosis, maintenance, and internal forces of the steel structure. CONSTITUTION: A method for estimating the long-term clamping force of the existing high tension bolt in consideration of the loss of a clamping force resulting from the creep on a coated surface is as follows. When a high tension bolt is coupled to a steel structure through friction welding, the creep stress and the residual fastening force of the high tension bolt are calculated after a fixed time using an equation, Creep=a+blog(t), where a and b are variables determined based on the thickness of inorganic zinc coating coated on the high tension bolt and t is time. Standards on safety inspection, diagnosis, maintenance, and internal forces of the steel structure are determined based on the calculation result.
