Abstract: The present invention relates to a frame panel having an improved reinforcing pattern. The frame panel includes a panel body having a front plate and a rear plate, which are integrally formed as a single body through a blowing process. The front plate has vertical groove patterns and horizontal groove patterns on the outside area except for the central area thereof, while the rear plate has vertical groove patterns and horizontal groove patterns on each of the central area and the outside area thereof, thus forming rectangular reinforcing groove patterns, with a diagonal groove pattern diagonally extending upwards from the lower end of a side of the rectangular reinforcing groove pattern provided on the outside area of the rear plate such that the diagonal groove pattern passes through the rectangular reinforcing groove pattern provided on the central area of the rear plate.

Abstract: The present invention relates to a plastic panel, and more particularly, to a plastic panel which comprises inner and outer panels wherein a bonding groove to be coated with an adhesive is formed on any one of the inner and outer panels. According to a preferred embodiment of the present invention, the bonding groove is formed on any one of the inner and outer panels, while a protrusion is formed on a bonding surface of the other of the inner and outer panels. Accordingly, since the bonding groove is bonded to the bonding surface of the inner or outer panel, the bonding groove can serve as a guide when the adhesive is applied. Thus, the adhesive can be applied at a uniform thickness to correct positions even though it is manually applied, and even an adhesive with certain fluidity can be prevented from leaking to the outside.
