This method has the disadvantage of poor workability because it is complicated, requires special processing, and the work of threading the nut onto the bolt must be performed for each bolt at the work site.

The present invention eliminates the above-mentioned drawbacks when connecting and fixing columns and frame materials using bolts and nuts. By screwing on the bolt and drilling a port insertion part large enough to insert the head of the screwed bolt into the connecting surface of the other column or frame material, the bolt can be inserted. An opening made in a plane perpendicular to the connecting surface of the column or frame into which the bolt head is inserted, and the bolt head is positioned within the column or frame by inserting the bolt insertion part. After inserting a washer that has a groove-like opening slightly wider than the diameter of the threaded part of the bolt and having one of its width and height longer than the width or height of the bolt insertion part and attaching it to the bolt, the bolt is inserted. Columns or frame materials can be connected and fixed without exposing the bolts and nuts to the outside, and after the connection and fixation is completed, bolts and To provide a method for connecting and fixing pillars or frame members in which nuts can be easily hidden.

More specifically, when connecting and fixing pillars or frame materials with bolts and nuts, the present invention fixes the nut to a bolt insertion part drilled in the connecting surface of one of the pillars or frame materials, and screws the bolt into this nut. After tightening, drill a port insertion part large enough to insert the bolt head into the connecting surface of the other column or frame material, and then touch the connecting surfaces of the columns or frame materials to be connected together. By inserting the head of the bolt screwed into the nut into the other column or frame material by inserting it through the bolt insertion part, and then inserting it into the port insertion part in a plane perpendicular to the connecting surface of that column or frame material. A washer having a groove-like opening slightly wider than the diameter of the threaded part of the bolt and one of the width and height of which is longer than the width or height of the bolt insertion part is inserted into the opening bored in communication with the bolt. The present invention relates to a method for connecting and fixing pillars or frame members, which is characterized in that the bolts are attached to bolts and the bolts are tightened using a tool through an opening.

Numeral 4 is a nut fixed to the bolt insertion part 2a of the column or frame material 2.A normal nut is used as this nut 4, and this nut is welded to the bolt insertion part 2a.
There is a method in which it is fixed to a, and a flanged nut, which is currently commercially available from Pop Rivet Fastener Co., Ltd. under the name of Pop Nut, and which is installed in the state shown in Figure 6 I and then deformed to the state shown in Figure 6 ■ and then fixed. The method used can be adopted.

Reference numeral 5 designates a washer that is inserted through the opening 1b of the column or frame material 1 and attached to the port 3 inserted into the column or frame material 1, and the shape of this washer 5 is such that the head of the bolt 3 can be inserted through it. and a groove-like opening 5b slightly wider than the diameter of the threaded portion of the bolt 3, and one of the width and height is equal to or equal to the width of the bolt insertion portion 1a of the column or frame material 1. It needs to be longer than it is tall.

In such a structure, in order to connect and fix the pillars or frame members 1 and 2, a nut 4 is first fixed to the port insertion portion 2a bored in the connecting surface of one of the pillars or frame members 2.

When using an ordinary nut as this nut 4,
As shown in Fig. 2, it is simple and preferable to adopt a method of fixing the column or frame material 2 inside the column or frame material 2 by welding. However, when fixing the material by welding in this way, before shaping the column or frame material 2, nuts are pre-installed. 4, or after forming the column or frame material 2 as shown in FIG. Either method may be employed, including applying the bolt to the bolt insertion portion 2a and welding.

Further, as the nut 4, use a flanged nut 4 as shown in FIG. 6, which is made of a slightly softer material, and insert the flanged nut 4 with the flanged part caught in the port insertion part 2a, as shown in FIG.
