DECORATIVE METAL COVER, AND DECORATIVE COVER
To provide a decorative metal cover with pavement material which is less likely to rattle inside the filled recess when sand is filled in the filled recess together with the pavement material.SOLUTION: A box frame-shaped decorative metal cover 21 has a filled recess 30 for filling with pavement materials, which is formed by a bottom plate part 22 and a side wall part 23 raising from the periphery of the bottom plate part 22. There are multiple ridges 36 and/or grooves 37, which extend vertically, formed on the inner surface 32 of the side wall part 23. With this configuration, the ridge 36 and groove 37 prevent the sand filled in the filled recess 30 together with the pavement material from being flown horizontally with respect to the inner surface 32 of the filled recess 30, resulting in a reduction of the rattling of the pavement materials using the same amount of sand as conventional one.SELECTED DRAWING: Figure 7
【課題】舗装材とともに砂を充填凹部に充填した場合に、充填凹部の内部で舗装材ががたつき難い化粧用金属蓋体を提供する。【解決手段】底板部２２と、該底板部２２の周囲から立ち上がる側壁部２３とによって、舗装材を充填する充填凹部３０が形成された箱枠状の化粧用金属蓋体２１にあって、側壁部２３の内側面３２に、略上下方向に延びる突条３６及び／又は凹溝３７を複数本形成する。かかる構成とすれば、舗装材とともに充填凹部３０に充填される砂が、充填凹部３０の内側面３２に対して水平方向に流動するのを突条３６や凹溝３７によって抑制できるため、砂の充填度合いが同じ程度でも、舗装材のガタツキを低減できる。【選択図】図７
