Description

[0001] JOINT FOR CONNECTING SQUARE PIPE [0002]

The present invention relates to a joint for connecting a square pipe, and more particularly, to a square pipe joint for connecting a square pipe to a square pipe connecting a square pipe for use in constructing various types of structures in a simple and rigid manner in various directions and lengths, This invention relates to a joint for pipe connection.

Generally, in order to construct various structures such as shelves, shelves, and architectural structures, square pipes of a certain length are constructed by mutually orthogonalizing each other or arranging them in various directions such as parallel and vertical. Joint joints are used.

For this purpose, as a conventional technique for connecting square pipes with a simple fitting structure when connecting a square pipe and a square pipe, there is disclosed a "rectangular pipe edge fitting"

The rectangular pipe 120 is integrally formed by integrally protruding from the body 110. The pipe 120 is forcedly inserted into the square pipe and the square pipe to be assembled.

However, in the above-described conventional technique, the square pipes are assembled by interference fit without any separate fastening means, so that impact and flow are generated at the already-connected connecting portions on the other side to lower the cohesiveness, There is a problem that the joined joint inserted into the square pipe can easily fall out.

Also, during frequent fitting and separating, the joints are worn out and loosened, and the connection is not rigid, so that the angle between the square pipes connected to each other may be changed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms as used herein include plural forms as long as the phrases do not expressly express the opposite meaning thereto. Means that a particular feature, region, integer, step, operation, element and / or component is specified, and that other specific features, regions, integers, steps, operations, elements, components, and / And the like.

Although not defined differently, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Commonly used predefined terms are further interpreted as having a meaning consistent with the relevant technical literature and the present disclosure, and are not to be construed as ideal or very formal meanings unless defined otherwise.

The embodiment of the present invention described with reference to the drawings specifically illustrates an ideal embodiment of the present invention. As a result, various variations of the illustration, for example variations in the manufacturing method and / or specification, are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture. For example, the regions shown or described as being flat may have characteristics that are generally coarse / rough and nonlinear. Also, the portion shown as having a sharp angle may be rounded. Thus, the regions shown in the figures are merely approximate, and their shapes are not intended to depict the exact shape of the regions, nor are they intended to limit the scope of the present invention.

The square pipe connecting joint J according to an embodiment of the present invention mainly comprises a main cover plate 10 and a side plate 20 and a reinforcing cutout groove 30 and a reinforcing step 40 .

Here, the main cover plate 10 has a predetermined width, which is the same as the width of the upper or lower surface of the square pipe P, and is coupled to the upper surface and the lower surface of the square pipe P, respectively.

To this end, the main lid plate 10 is bent to form a '' 'shape to support the two square pipes P to be connected in a' '' shape, or two or three square pipes P Or may be formed to have a 'T' shape to support a connection in a 'T' shape or a '+' shape to support a connection of four square pipes P in a '+' shape have.

Here, the side plates 20 may be formed on both sides of the main cover plate 10 and bent downward in a predetermined width. The side plates 20 are in close contact with the side portions of the square pipe P connected to each other. The side plates 20 may be folded and connected in the form of 'a', 'T', and '+' like the main cover plate 10.
