    • A steel plate reinforcing sheet that can reduce distortions of the steel plate without reducing its reinforcing property and can also prevent abrupt deformations at end portions thereof with respect to a direction extending along a curving direction of a curved steel plate. The steel plate reinforcing sheet 1 comprising a restricting layer 2 and a reinforcing layer 3, wherein slits 4 are formed in both end portions of the restricting layer 2 to extend over an entire length of the restricting layer 2 with respect to a direction substantially orthogonal to a direction in which the both end portions confront each other and also arranged so that a length defined between the slits 4 can be 40% or more of a total length of the steel plate reinforcing sheet 1 with respect to a direction parallel to the length between the slits 4. Then, the steel plate reinforcing sheet 1 is adhesively bonded to the curved steel plate 5 so that the slits 4 extend along a direction substantially orthogonal to the curving direction of the curved steel plate 5 and, then, is foamed and cured.
    • 一种钢板增强板,其能够减小钢板的变形,而不会降低钢板的增强性,并且还能够防止在弯曲钢板的弯曲方向延伸的方向的端部处的突然变形。 钢加强板具有如长度和宽度所限定的大致矩形形状,以及将钢板增强板的长度平分的假想线的两侧的两个端部。 钢板增强片是包括限制层和加强层的层压体,其中限制层的每个端部包括至少一个狭缝。 每个狭缝直接或间接地延伸穿过钢板增强板的整个宽度,并且最靠近假想线的两个狭缝限定狭缝之间的最小距离。 最小距离与钢板增强板的长度平行,相当于钢板增强板的长度的40%以上。
