とともに、前記４枚の側型枠２同志を相互に固定手段４
により固定した構造の型枠５が周知である。(Prior Art) Conventionally, as shown in FIGS. 3 and 4, molds used for manufacturing, for example, flat cement molded products, have been used.
Four side formworks 2 having a height corresponding to the thickness of the precept-shaped product are arranged in a rectangular manner on the upper surface of one copper surface plate 1, and they are fixed to the surface plate by fixing means 3 such as bolts and bottles. At the same time, a means 4 for fixing the four side formworks 2 to each other is used.
A formwork 5 having a fixed structure is well known.
（発明が解決しようとする課題）
ところが前記構造の型枠においては次のような問題があ
った。(Problems to be Solved by the Invention) However, the formwork of the above structure had the following problems.
（１）前記型枠５は通常鋼から製作されているので全体

（２）前記定盤１に対する側型枠２の固定構造が複雑で
あるため、固定作業が繁雑になり相当時間を要すること
。(2) Since the structure for fixing the side formwork 2 to the surface plate 1 is complicated, the fixing work is complicated and takes considerable time.
（３）セメント戒形品の形状、大きさに応じた種々の測
型枠２を準備しなければならないこと。(3) It is necessary to prepare various measuring forms 2 according to the shape and size of the cement shaped product.
（４）セメント成形品として周縁が非直線的な形状、例
えば円曲面、任意曲面を有しているものを成形しようと
する場合、測型枠そのものの製作が困難であること。(4) When trying to mold a cement molded product whose periphery has a non-linear shape, such as a circular curved surface or an arbitrary curved surface, it is difficult to manufacture the measuring frame itself.
（５〉前記型枠５が鋼から形成されているので錆易く、
そのため必要に応じて使用する側型枠２に対して防錆手
段を施して保管する必要があること。(5> Since the formwork 5 is made of steel, it is easy to rust,
Therefore, it is necessary to store the side formwork 2 with anti-corrosion measures applied as needed.
（６〉前記固定手段３を前記定盤１に固定するための孔
〈図示なし〉等が前記定盤１に多数個穿設されるので、
その孔を中心にして前記定盤１の破損が進行してその寿
命が短くなること。(6) Since a large number of holes (not shown) etc. for fixing the fixing means 3 to the surface plate 1 are bored in the surface plate 1,
The damage to the surface plate 1 progresses around the hole, and its lifespan is shortened.
そこで、本発明者らは前記の問題を解消できる、又は軽
