More particularly, the present invention relates to a multifunctional bulletin board connecting member, In particular, the present invention relates to an eco-friendly multipurpose bulletin board connecting member and a prefabricated multipurpose bulletin board using the eco-friendly bullet board connecting member.

In general, bulletin boards are used in various places in our society. There is no place where bulletin boards such as companies, schools, military units, farms are used as well as at home. However, these conventional bulletin boards are so simple that their functions are so limited that the technology development in this field is very poor.

In addition, it has been common to post a bulletin board with a pushpin on a bulletin board made of a wood plywood fixed on a wall of a bulletin board, or to attach the contents to a bulletin board to which a magnet can be attached. However, there has been no improvement in the performance of the bulletin board.

Therefore, when the above-mentioned board is formed of wood, the corners of the frames constituting the four sides are cut to 45, the cut surfaces are joined and fixed to each other, and then the board is posted on the inner side, I am making. However, since the wooden board is made of wood, it can be broken easily for a long time.

In order to solve the above-described problem, the frame is formed of stainless steel, and each corner is cut into 45 like the wood board, or the contact portions of the frames adjacent to each other are welded to form a billboard.

However, in the case of joining the frame through welding as described above, there is a problem that the manufacturing cost of the bulletin board increases because the welding cost is high. Particularly, in the case of the above-mentioned welding, special welding is required. In this case, since the cost of the welding machine is expensive and the price of the welding rod is too high even if the welding machine is rented, it can not be used easily.

In addition, since it is impossible to assure the quality of welding beyond the skilled worker when welding, it is not possible to produce a bulletin board of good quality, and even if it is a skilled worker, since beads are not uniformly generated in the joint portion during welding, There was a problem that the product could not be obtained.

In particular, since bulletin boards are manufactured using welding, there has been a problem in that it is not environmentally friendly, such as the generation of harmful gases.
