2. Description of the Related Art Generally, when constructing a tent, a tent, a rafter, a purlin girder or the like is formed by a tent stretch frame made of steel frame material, steel pipe material, or the like, and a cloth sheet, a vinyl sheet, or the like is formed on the skeleton. Tent membrane material is stretched.
Here, in the framework, a purlin girder material is arranged between the columns, but generally, a support member such as a pin or a bolt is inserted into a mounting portion such as a pin hole or a bolt hole provided in the column. The purlin girder material is supported on the struts.

By the way, as a base metal fitting for a tent for standing and holding such a column, conventionally, a line for arranging several columns has been determined, and the distance between the columns has been measured using a measuring instrument such as a measure. On the basis of this, a tent base bracket is fixed to the ground with an anchor or the like, and then a post is inserted, or the post is fixed by a bolt or the like, and this is erected and held.
