Customers, even if they are not skilled, can easily assemble the furniture themselves, providing convenience in assembly. It is about a modular furniture frame with non-exposed assembled parts.

In general, the frames that make up the skeleton of steel furniture such as display cases mainly use square or circular section steel. Frames using such section steel arrange vertical and horizontal bars in cross directions to protect against the action of load or external force. It maintains its shape while resisting.

In such a frame, a connection structure is essentially required to connect the vertical bars and horizontal bars arranged in the cross direction, and various methods for connecting and fastening such a connection structure, such as a welding method or a bolting method, are generally used.

In the case of steel furniture, the bolting method is mainly used. This method involves arranging horizontal bars across vertical bars, attaching the connecting parts so that they are in contact with the vertical bars and horizontal bars, and then connecting and assembling the vertical bars and horizontal bars using fastening means such as bolts. This is being used.
