本考案は、熱膨張してもひび割れすることのな
い耐久性に秀れた合成樹脂製定規板に関するもの
である。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a synthetic resin ruler plate that is highly durable and does not crack even when thermally expanded.

てしまつたりする問題があることが確認された。 However, with this conventional product, there is no problem when the length of the ruler plate is about 50 cm, but when the length of the ruler plate is about 100 cm, the coefficient of thermal expansion between the acrylic ruler plate and the stainless steel wire drawing plate becomes It has been confirmed that this difference causes problems such as cracking of acrylic plates, which are less strong than stainless steel, and of bending of stainless steel wire drawing plates.
これは、熱膨張率の異なる部材が伸縮性を有し
ない接着剤により接着さしめられている為、アク
リル板が伸びても接着剤がその伸びに伴つて伸び
ないことにより生ずるものである。 This occurs because members with different coefficients of thermal expansion are bonded together with an adhesive that does not have elasticity, so even if the acrylic plate stretches, the adhesive does not stretch along with the stretching.

ことはない。 In addition, a synthetic resin ruler plate 1 and a metal wire drawing plate 3 are also included.
Since the bonding material 4 has elasticity even if the elongation length due to thermal expansion is different from the synthetic resin as shown in FIG. 4 or FIG. 5 which is an enlarged drawing of FIG. The synthetic resin ruler plate 1 is elongated as the ruler plate 1 is elongated, so that no cracks or the like occur in the synthetic resin ruler plate 1.

When a ruler plate made of acrylic resin with a length of 100 cm and a thickness of 10 mm is glued to the opposite edge of the graduated edge with a stainless steel drawing board with a cross section using a commercially available epoxy adhesive, the acrylic resin ruler plate is heated to 60°C. Experiments have confirmed that cracks occur in ruler plates made of

リル樹脂製定規板にひび割れは生じなかつた。 On the same acrylic resin ruler plate, a stainless steel cross-sectional wire drawing plate 3 is formed, and an acrylic adhesive layer 5 is formed on both sides as shown in FIG. The ruler plate was glued using a bonding material 4 (product name: Scotch VHB bonding material Y-4920 manufactured by Sumitomo 3M Ltd.) that has elasticity and adhesive properties and has a thickness of about 0.4 mm. When heated to 60°C, no cracks were observed in the acrylic resin ruler plate.
