【発明の詳細な説明】 産業上の利用分野 この発明は引張ボルト形式によって接合したラーメンを
なす鉄骨軸組の柱脚を露出形式によつて固定してある建
築架構に関するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building frame in which a column base of a steel framework which forms a rigid frame joined by a tension bolt type is fixed by an exposed type.

きなくなる。Problems to be Solved by the Invention Among the columns and beam joints of steel frameworks that are generally used in the past, the method of joining by the tension bolt type is a bracket or joint part from the column as compared with friction joining by high-strength bolts. Since there are no protrusions such as attachment plates and bolt heads, it has good transportation efficiency and storage, and compared with welding joining, there are many advantages such as easier construction management on site, but column materials Since the ends of the beam members are butted against the ends of the joining brackets protruding from the surface or the pillars, there is no play to absorb construction errors, and high construction accuracy is required. Moreover, the steel column base has its base plate fixed with anchor bolts prior to erection, but since the clearance between the anchor bolt insertion hole of the base plate and the anchor bolt is generally small,
It is difficult to correct position and dimensional errors in the process of building. Also, it is easy to construct a steel column by simply increasing the anchor bolt insertion hole of the base plate to increase the clearance, but when a horizontal force is applied, lateral slippage occurs and the column base is completely It becomes impossible to fix it easily.
