産業上の利用分野
本考案はコンクリート打設屋根、殊に流れ屋根
のコンクリート打設レベルの設定に好適に用いら
れる埋込定規に関する。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a built-in ruler suitably used for setting the concrete pouring level for concrete pouring roofs, especially flow roofs.

る。Prior Art Conventionally, concrete cast flow roofs required the surface to be leveled and corrected with mortar to ensure flatness and thickness as a post-concrete process. This leveling mortar is used as a base for roofing, such as rubber sheet roofing, shingle roofing, etc., and requires highly accurate flatness.

であることにも起因し、もつと均し打ちできれば
モルタルも極めて軽度の均し作業で足りる。Problems that the invention aims to solve As mentioned above, in the past, after pouring concrete, the concrete was so uneven that it could not be used as a roofing base, so leveling and mortaring was an essential step. Moreover, this leveling and mortaring requires skilled techniques and time, which lengthens the construction period and increases construction costs. This is due to the fact that the concrete surface is rough, and if it can be leveled, very light leveling of the mortar is sufficient.
本考案は上記現状を改善すべく以下に述べるコ
ンクリート打設屋根用埋込定規を創案したもので
ある。 In order to improve the above-mentioned current situation, the present invention was created by devising an embedded ruler for concrete poured roofs, which will be described below.
