Description

本発明は、所要幅員と左右水路壁が任意角度に形成可能な門形ブロック製造用型枠に関する。   The present invention relates to a portal block manufacturing form in which a required width and left and right channel walls can be formed at an arbitrary angle.
図12(a)に示すのは、土木施工において水路用または上下に連結して暗渠ブロック等に多用されている門形ブロック10であり、(b)に示すのは、門形ブロック10を上下に連結した暗渠ブロック20である。しかし、従来技術の門形ブロック製造用型枠では、所要幅員を調整可能なものも少なく、左右水路壁11,12が端部10F,10Rに対し平面視下で直角(以下、水路壁の角度とは、端部10F,10Rに対する平面視下での角度をいう)の製品しかできなかった。 FIG. 12 (a) shows a gate-shaped block 10 that is frequently used for a conduit or connected to the top and bottom in civil engineering work, and is shown in FIG. 12 (b). Is a culvert block 20 connected to However, in the conventional gate-form block manufacturing form, few widths can be adjusted, and the right and left water channel walls 11 and 12 are perpendicular to the end portions 10F and 10R in a plan view (hereinafter, the angle of the water channel wall). Means an angle in plan view with respect to the end portions 10F and 10R) .
前記理由により、水路と道路あるいは道路と道路が立体交差する施工現場では、道路下等に門形ブロック10または上下に連結した暗渠ブロック20を潜らせたりするが、門形ブロック10や暗渠ブロック20の図中一点鎖線で示す延長線C1と前記道路等が直交する以外の現場では、見場を良くするため採算を度外視して製造工場で門形ブロックの前端部10F、後端部10R等の所要位置に角度を付けることが多く望まれ、門形ブロック製造用型枠の前後端部の所定位置に所要角度の仕切板をその都度作って電溶で仮付けして打設したり、通常に製造した門形ブロック10の所望される前後何れかの端部10F,10Rをワイヤソウ等で切断cu(図中破線で示す)して納品することが多く、このような煩雑な方法で端部加工の要望に答えているが、製造の初期段階から門形ブロック10の左右水路壁11,12に角度を付けて形成することはできなかった。 For the above reasons, at the construction site where the waterway and the road or the road and the road intersect three-dimensionally, the gate-shaped block 10 or the culvert block 20 connected to the top and bottom is hidden under the road or the like. In the site other than the extension line C1 indicated by the alternate long and short dash line in the figure and the road etc. are orthogonal to each other, the front end portion 10F, the rear end portion 10R, etc. It is often desirable to add an angle to the required position. Usually, a partition plate with the required angle is created at a predetermined position on the front and rear ends of the portal block manufacturing formwork, and is temporarily attached by electromelting. In many cases, the end blocks 10F and 10R before and after the portal block 10 manufactured in the manufacturing process are cut with a wire saw or the like (indicated by a broken line in the figure) and delivered. Answer to processing request However, it was not possible to form the right and left water channel walls 11 and 12 of the portal block 10 at an angle from the initial stage of manufacture.
