Abstract

PURPOSE:To utilize effectively a plate by cutting in advance the surface and the rear side of the plate, turning a damaged plate inside out, and reusing it. CONSTITUTION:The surface 10a and the rear side 10b of a sliding plate 10 are prepared in parallel, and both its surfaces are brought to cutting operation in advance with a prescribed accuracy so that they can be used as sliding surfaces. Also, the plate 10 is tightened up by a band steel 12 for preventing a deformation, and also a metal flow hole 11 is formed at a prescribed position. According to this constitution, if one surface of the plate 10 is damaged and becomes unendurable against use, the plate 10 is turned inside out and used since the surface 10a of the plate and the rear side 10b are parallel. The rear side 10b is also brought to cutting operation in advance with a prescribed accuracy, therefore, it can be reused immediately. By this method, the plate 10 can be utilized effectively.

突出部は無い。Hereinafter, examples of the present invention will be explained based on the drawings. 2 shows a fixed or sliding plate 10 according to the present invention, whose front surface 10a and back surface 10b are made parallel, and both surfaces are predetermined so that they can serve as sliding surfaces. Precision cutting shall be performed. Of course, there are no protruding parts.

されているＴこめ直ちに再使用が出来得るのである。With this structure, if one side is damaged to a certain degree and becomes unusable, it is only necessary to turn the plate over because the front surface 10a and back surface 10b of the plate are parallel. No change in plate thickness. Furthermore, the T-piece, whose back surface 10b has been cut to a predetermined precision, can be immediately reused.

さらに本技術は突出部付プレートにも適用出来る。Furthermore, this technology can also be applied to plates with protrusions.

これを第３図以下に示す。This is shown in Figure 3 and below.

以上強固に連結されるようにしなくてよい。FIG. 3 shows a case in which a protruding member 13 formed separately from the plate 10 is bonded with a fire-resistant adhesive. Next, when the plate surface 10a is damaged, the protruding member 13 on the back surface 10b is removed, the plate 10 is turned over, and the back surface 10b is used as a sliding surface. The protruding member 13 is connected to the plate so as not to leak, but in order to facilitate the removal of the protruding member, it is not necessary to connect the plate more firmly than necessary as long as the protruding member 13 does not leak.
