Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows pillars or frame materials to be connected and fixed with bolts and nuts easily and reliably without exposing the bolts and nuts used for the connection and fixation to the outside of the pillar or frame material. The present invention relates to a method for connecting and fixing pillars or frame members, which allows for easy connection and fixing work.

In general, in architecture and other sectors, there are many cases where it is necessary to connect and fix columns and frames, such as columns and columns, panel frames and panel frames, and columns and panel frames.

When connecting and fixing columns and frame materials in this way, there are various ways to connect and fix them, such as welding, riveting, adhesive bonding, and tightening with bolts and nuts, depending on the material of the columns and frame materials. However, among these methods of connection and fixation, the method of connection and fixation using bolts and nuts is widely used because it does not require special equipment or techniques and can be done manually using simple tools. has been done.

However, when connecting and fixing columns and frame materials using bolts and nuts, if you simply drill a bolt hole in the column or frame material through which the threaded part of the bolt can pass, it is necessary to Not only are the heads of nuts and screws of nuts and bolts exposed, which is undesirable in terms of design, but the exposed parts often get in the way of other work, making the connection and fixing work to eliminate the exposed parts complicated. This requires special processing and the use of special bolts and nuts, which is undesirable in terms of the effort and cost required for connection and fixation.Moreover, the work of threading nuts onto bolts must be done for each bolt at the work site. This had the disadvantage of poor workability because it required a lot of work.

The present invention eliminates the above-mentioned drawbacks when connecting and fixing columns and frame materials using bolts and nuts. A bolt insertion part wide enough to allow the insertion of the bolt was drilled, and a bolt with a nut was inserted through an opening formed perpendicular to the connecting surface of the frame material, and the bolt was drilled into the connecting surface. The bolts and nuts are tightened using tools inserted through the port insertion portions and inserted from the openings respectively, and the 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, the columns or frame materials are connected and fixed. To provide a method for connecting and fixing pillars or frame materials in which bolts and nuts can be easily hidden simply by attaching a surface frame such as a decorative board to the surface of the pillar or frame material.

More specifically, when connecting and fixing pillars or frame materials with bolts and nuts, the present invention allows a bolt with a nut or a nut-back bolt equipped with a washer to be inserted into a surface perpendicular to the connecting surface of the pillar or frame material, and the bolt and the nut Form an opening large enough to insert a tool for tightening the parts, and drill a bolt insertion part that communicates with the opening in the connecting surface of the pillar or frame material. After inserting the bolt with nut inserted through the opening of the material into the bolt insertion part of the column or frame material where the connecting surface is in contact, use the tool inserted through the opening of each column or frame material to connect the bolt and nut. The present invention relates to a method for connecting and fixing pillars or frame members, which is characterized by tightening.

EMBODIMENT OF THE INVENTION Hereinafter, the method for connecting and fixing pillars or frame members according to the present invention will be explained in detail with reference to the drawings.

It does not change the gist of the present invention to provide the same effect as the shape.

In the method of the present invention as described in detail above, a bolt insertion portion and an opening communicating with the bolt insertion portion are provided in each column or frame material to be continuously fixed, and bolts and nuts are buried in the column or frame. This is a method for reliably and firmly connecting and fixing columns or frame materials in a state in which the columns or frames are hollow, as in the illustrated example, or solid materials. The bolts and nuts used to connect and fix frame materials are stored inside the pillar or frame material, so they do not spoil the appearance and are aesthetically pleasing. There are no holes or nuts in the way, and after connecting and fixing the pillars or frame materials, all you need to do is attach a surface to seal the opening perpendicular to the connecting surface, so post-processing is also easy. It is easy to use, and in terms of workability, because it involves inserting a bolt with a nut, there is no need for the troublesome work of screwing a nut onto the threaded tip of a bolt inside a narrow column or frame material, and the bolt or nut does not fall off. It has various advantages, such as eliminating the need to take account of this and allowing work to be done efficiently in a short time, and its industrial value is extremely large.
