The stepping plate 3 is placed flat on the upper open surface 6 of the frame 2.

例えば勝手口等に面する建物の立ち上がり基礎２５に接して又は近接して基礎プレート１、箱枠２、踏みプレート３を組み立て設置する。 For example, the foundation plate 1, the box frame 2, and the tread plate 3 are assembled and installed in contact with or close to the rising foundation 25 of the building facing the doorway.

即ち箱枠２は上部開放面６と下部開放面７によって上下に開放された空洞５を有し、該空洞５を画成する四側板８の下端面を上記基礎プレート１の上面に設置し、該空洞５を画成する四側板８の上端面に上記踏みプレート３を平置きし、所要の蹴上がり高さを有する踏み面９を形成する。 That is, the box frame 2 has a cavity 5 opened up and down by an upper open surface 6 and a lower open surface 7, and the lower end surface of the four side plate 8 defining the cavity 5 is installed on the upper surface of the base plate 1. The tread plate 3 is laid flat on the upper end surface of the four side plate 8 defining the cavity 5 to form a tread surface 9 having a required kicking height.

上記箱枠２と基礎プレート１は設置面において嵌合し、相対位置を設定する構成とする。 The box frame 2 and the base plate 1 are fitted on the installation surface to set the relative position.

その嵌合構造例として基礎プレート１の上面の四辺と平行に環状の溝又は段差部から成る環状受容部１０を設け、該環状受容部１０内に箱枠２の四側板８の下端を嵌合する。換言すると基礎プレート１上面の上記環状受容部１０内域に該環状受容部１０にて囲まれたランド部１１を形成し、該ランド部１１を箱枠２の下部開放面７を形成する下部開口内に嵌合し、ランド部１１周面にて四側板８の下端内周面を規制する。 As an example of the fitting structure, an annular receiving portion 10 comprising an annular groove or a step portion is provided in parallel with the four sides of the upper surface of the base plate 1, and the lower ends of the four side plates 8 of the box frame 2 are fitted into the annular receiving portion 10. To do. In other words, a land portion 11 surrounded by the annular receiving portion 10 is formed in an inner region of the annular receiving portion 10 on the upper surface of the base plate 1, and the lower opening that forms the lower open surface 7 of the box frame 2 is formed on the land portion 11. The lower end inner peripheral surface of the four side plate 8 is regulated by the land portion 11 peripheral surface.

又上記箱枠２と踏みプレート３は平置き面において嵌合し、相対位置を設定する構成とする。 The box frame 2 and the stepping plate 3 are fitted on a flat surface to set a relative position.

The upper ends of the four side plates 8 are fitted. In other words, a land portion 24 surrounded by the annular receiving portion 23 is formed in the inner region of the annular receiving portion 23 on the lower surface of the step plate 3, and the land portion 24 is formed as an upper portion forming the upper open surface 6 of the box frame 2. The upper end inner peripheral surface of the four side plate 8 is regulated by the land portion 24 peripheral surface by fitting into the opening.

又上記箱枠２を上下複段に重ね置きし、各箱枠２を重ね置き面において嵌合し、蹴上がり面の蹴上がり高さを必要な高さに設定すると共に相対位置を設定する。 Further, the box frames 2 are stacked in the upper and lower stages, the box frames 2 are fitted on the stacking surfaces, the kicking height of the kicking surface is set to a necessary height, and the relative position is set.

上記箱枠２相互の重ね置き面における嵌合構造例として、箱枠２の四側板８の上端面の外周側（又は内周側）に沿い嵌合用の環状凸壁１２を立ち上げると共に、該環状凸壁１２の内周面（又は外周面）に沿い、即ち四側板８の上端面の内周側（又は外周側）に沿い環状段部１３を形成する。 As an example of the fitting structure in the stacking surface between the box frames 2, the annular convex wall 12 for fitting is raised along the outer peripheral side (or inner peripheral side) of the upper end surface of the four side plate 8 of the box frame 2, An annular step portion 13 is formed along the inner peripheral surface (or outer peripheral surface) of the annular convex wall 12, that is, along the inner peripheral side (or outer peripheral side) of the upper end surface of the four-side plate 8.

同様に箱枠２の四側板８の下端面の内周側（又は外周側）に沿い嵌合用の環状凸壁１４を立ち上げると共に、該環状凸壁１４の外周側（又は内周側）に沿い、即ち四側板８の上端面の外周側（又は内周側）に沿い環状段部１５を形成する。 Similarly, an annular convex wall 14 for fitting is raised along the inner peripheral side (or outer peripheral side) of the lower end surface of the four side plate 8 of the box frame 2, and on the outer peripheral side (or inner peripheral side) of the annular convex wall 14. An annular step portion 15 is formed along the outer peripheral side (or inner peripheral side) of the upper end surface of the four side plate 8.

上記四側板８上端面に形成した環状凸壁１２及び環状段部１３と、上記四側板８下端面に形成した環状凸壁１４及び環状段部１５とは、上記の如く相対配置にし、箱枠２の天地を逆にしても重ね置きし嵌合できるようにする。 The annular convex wall 12 and the annular step portion 13 formed on the upper end surface of the four side plate 8 and the annular convex wall 14 and the annular step portion 15 formed on the lower end surface of the four side plate 8 are arranged relative to each other as described above. Even if the top and bottom of 2 are reversed, they can be stacked and fitted.

よって複数の箱枠２を上下に重ね置きした場合、上段の箱枠２の四側板８下端の環状凸壁１４が同下段の箱枠２の四側板８上端の環状段部１３に嵌合し、同時に下段の箱枠２の四側板８上端の環状凸壁１２が同上段の箱枠２の四側板８下端の環状段部１５に嵌合し位置決めする嵌め合い構造を形成する。 Therefore, when the plurality of box frames 2 are stacked one above the other, the annular convex wall 14 at the lower end of the four side plate 8 of the upper box frame 2 is fitted to the annular step portion 13 at the upper end of the four side plate 8 of the lower box frame 2. At the same time, a fitting structure is formed in which the annular convex wall 12 at the upper end of the four-side plate 8 of the lower box frame 2 is fitted and positioned on the annular step portion 15 at the lower end of the four-side plate 8 of the upper box frame 2.
