Description

Prefabricated frame structure {Prefabricated frame structure}

The present invention relates to a prefabricated frame structure, and more specifically, a frame structure used for displaying or storing various items, or supporting or mounting various industrial equipment, is constructed as a prefabricated structure made of a number of parts, and processing tolerances between parts are maintained during assembly. The present invention relates to a prefabricated frame structure that can quickly, easily and robustly manufacture frame structures required in various sizes and shapes depending on the intended use by further providing a means for resolving assembly tolerances.

When displaying or storing goods at an exhibition or store, or when supporting or mounting various equipment at an industrial site, a frame structure made of metal or synthetic resin is generally first installed as a basic skeleton, and then shelves or doors are installed as necessary. Various storage means or support means are additionally installed.

In addition, when storing or supporting items with a large load, such as industrial equipment, a frame structure made of metal is mainly used for durability. The conventional metal frame structure is made of metal cut to a certain length and horizontally and horizontally as needed. It was common to manufacture by welding in the vertical direction.

However, when manufacturing a frame structure by welding like this, not only is a considerable amount of time and cost consumed in manufacturing and transportation, but the work is not easy even when there is a need to change the structure during use or to dismantle after use. There was a problem that a lot of cost was consumed.

In order to solve this problem, a prefabricated frame structure has been developed recently as disclosed in [Document 1] and [Document 2] below. Since this prefabricated frame structure does not require separate welding, it is easy to transport and manufacture the product. Not only is it easy, but it also has the advantage of being able to easily perform structural changes during use or disassembly after use.

However, in the case of the conventional prefabricated frame structures disclosed in [Document 1] and [Document 2] below, the processing tolerances or assembly tolerances generated during the production process or assembly process of each component are accumulated as the assembly is extended, so they are flat. There is a problem in that the shape of the frame structure, such as degree (parallelism) and perpendicularity, is difficult to maintain stably, and this problem is further aggravated as the size of the frame structure increases or the load of the article stored/supported in the frame structure increases.

In particular, in the case of prefabricated frame structures on which processing equipment or measuring equipment is mounted at industrial sites, if it is difficult to maintain a stable shape as described above, precise processing or measurement cannot be performed, which is a serious problem in which production efficiency is greatly reduced due to an increase in defective rates. causes.
