Description

plastic sheet

The present invention relates to building materials, especially a plastic board.

Simple buildings, such as scaffolding, have roofs constructed from multiple panels, which are usually modularized to facilitate calculation of usage and ease of construction. The conventional modular sheet has many shapes and structures, such as the new patents M490494, M380972 and the invention patent I506189, etc., mainly on the two sides of the sheet body are provided with fitting parts for two adjacent ones. The plates are connected to each other with their fitting parts. However, in the above-mentioned conventional structures, it is defined that the board body has a front and a back side, and two adjacent boards can only be fitted and connected to each other in the orientation that both are facing up. In the upper orientation, the shape of the fitting portion of the two cannot be matched and contacted. Therefore, it is necessary to pay attention to the orientation of the board during construction, which leads to more labor hours. On the other hand, since the panels are produced in modules, the construction restrictions on the orientation of the panels also limit the functionality of the panels.

In view of this, how to improve the above problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide a plastic sheet, the fitting parts on both sides of which are properly designed, so that two adjacent sheets can be fitted and connected to each other in any positive or negative state, thereby creating a space-dependent space.
