Description

  The present invention is designed to cover the finishing surface of the top of the buried material when it is buried on the sidewalk of the road with a buried material made of concrete, etc. The present invention relates to a protective cover for a column-buried material that protects the top edge from non-scattering of children and mischief of children.

  Conventionally, protective fences, car stops, traffic signs, etc. are installed on the sidewalks of roads.

  The conventional work of installing protective fences, car stops, traffic signs, etc. on the sidewalks of such roads is to dig a hole in the road, etc., and insert a post such as a protective fence, car stop, traffic sign, etc. into the hole. This is done by placing a buried material such as concrete and then finishing the top end of the unsolidified buried material arranged in the vicinity of the base end portion of the column and solidifying the buried material.

  However, when it is likely to begin to rain, the work schedule will be postponed or the ceiling will be lowered so that the finished surface of the concrete top will not be damaged or soiled by the rain. Only the top was finished.

  When there is not enough time for the construction period, construction may be forced if it is light rain, but in order to prevent damage to the top edge of the concrete due to rain, it is often used for so-called rain curing such as hanging a sheet near the top edge. Time was often taken.

  On windy days, dust and the like may scatter and adhere, and it may be necessary to finish the top end that has become dirty due to the adhesion of dust, which takes time.

  Even if it is a sunny day or a windless day, even if the top of the concrete is solidly finished, before the concrete top ends solidify, children's pranks and dogs and cats walk through the top. When the top end is damaged in this way, it is necessary to finish the top end again at a later date, which may be troublesome twice or three times.

  Due to the above circumstances, if the top of the cast strut burying material is not properly protected, the construction takes time and the construction management and construction process are often hindered.

  The present invention has been made in view of such circumstances, and can be installed by covering the top with a simple operation, and can be installed without rain curing even on rainy days. Strut embedding material that is not affected by dust scattering even on the sun, is less likely to be damaged by children's pranks, animals such as dogs and cats, and is convenient for construction management and construction process management The purpose is to provide a protective cover.
