あった。(Prior Art) A conventional gutter block (commonly called U-shaped groove block) manufacturing mold requires a dedicated mold for each size, such as water channel width and depth, and each shape, such as with and without a lid, Channel width 30 cm ~
A large number of molds are required depending on a wide range of combinations such as 1.5 m and depth of 30 cm to 1.5 m and various usage conditions, resulting in enormous equipment investment, complicated formwork maintenance, and profitability breakage during small-scale production. There is a drawback, and the core of the formwork is always provided with a draft angle of several degrees to facilitate demolding, but when the depth of the waterway becomes deeper, the adhesion with concrete is released, so the formwork is struck every time. Therefore, the product with the vertical inner surface of the waterway cannot be manufactured, because of the drawbacks such as the mold being damaged and deformed, the accuracy is deteriorated due to the deformation, and the appearance of the product is deteriorated. In order to solve the above-mentioned drawbacks, the applicant has already implemented a gutter block manufacturing form of utility model registration No. 1780989, and manufactures tens of thousands of gutter blocks of each size and shape (hereinafter referred to as gutters) per year. However, the high productivity of high-mix low-volume products that require frequent assembly changes is due to the fact that the shrinking of the core for the gutter and the insertion / removal of the waterway width adjustment plate take a few minutes, and the joint of the core shrinking part. The time loss of a few minutes to a few ten minutes required for cleaning the hose interferes with the smooth flow of the production line, and the traces of seams appear on the inner surface of the waterway of the gutter, which makes the formwork structure complicated and expensive. there were.

供することを目的とする。(Problems to be solved by the invention) The disadvantages of the conventional dedicated formwork, which required a large number of forms for the production of gutters under the production of a wide variety of products, were eliminated, and due to the recent rise in land, the channel width was narrow and deep. In response to the increasing demand for gutters (deep water channels), the disadvantages of the utility model registration No. 1780989 for the gutter block manufacturing formwork at the time of high-mix low-volume production were eliminated, saving labor and shortening the manufacturing time. The purpose is to provide a formwork that gives an aesthetic appearance.

Since the width of the core shrinks and separates from the concrete through the rod 105 axially attached to the core, it is possible to easily remove the mold without resistance. The two-dot chain line in the figure shows the mold when the core is contracted evenly to the left and right and both side plates are opened, and the broken line at the top is the side groove that was slightly raised to get over the end plate to remove the mold. At this time, the core is immediately restored to the proper channel width by the right rotation of the rotary shaft. In addition, the core 90 is provided with only the upper half of the bending radius on one side as an elastic body (providing a correctness of flexibility), and the core expansion / contraction mechanism (only one side shown in FIG. 5 expands and contracts) is connected to the lower part of the core on one side. You may. A stopper S in the figure is for limiting the descending position of the rod 105, and the rotating shaft is driven by the lateral pressure due to the concrete weight at the time of placing and the vibration of the powerful concrete compacting vibrator.
Prevent 120 from reversing. The two lifting mechanisms 150 mounted on the underframe 10 between the side plates 70, 75 and the core 90 are composed of two sets of elevators that can be operated separately.
The top end shaping member 80 is placed on the upper part, and the depth of the water channel is changed by the uniform ascending / descending operations of the two sets of elevators provided in the ascending / descending mechanism 150. Also, there is a difference in elevation so that the top end of the gutter is sloped. The wall thickness spacer 98 and the top end shaping member 80 having a width corresponding to the wall thickness can be replaced to increase or decrease the wall thickness on one side or both sides. It is also possible to manufacture a falling lid type by arranging on both sides.

If the waterway width is narrow (30 cm to 40 cm as an example) and the gable plate is a lightweight form, the structure is simple without splitting the gable plate into left and right. The cost is low, and core replacement when changing the waterway width etc. can be done easily in a short time, and if the front end plate is fully opened at the time of demolding, the side groove can be slightly raised and the mold can be demolded forward.

（効果） １）数台の型枠と交換部品で、天端勾配・水路深さ・壁
厚の異なる各種側溝が製造できるため、設備管理が合理
化できる。(Effects) 1) Since several gutters with different top slopes, water channel depths, and wall thicknesses can be manufactured with several molds and replacement parts, facility management can be rationalized.

２）脱型時の中子縮小と剥離が瞬時に行え、中子の掃除
が簡単で作業員の削減ができ、製造時間の顕著な短縮と
の相乗効果で、製品単価が下がる。2) The core size can be reduced and peeled off instantly when the mold is removed, the core can be easily cleaned, the number of workers can be reduced, and the product cost can be reduced due to the synergistic effect of significantly shortening the manufacturing time.

３）水路内面が垂直な、通常の側溝・深水路の製造が可
能になり、深水路の脱型時に発生しやすいクラックもな
くなり、水路内面の美観がよくなった。3) It became possible to manufacture normal gutters / deep water channels in which the inner surface of the water channel was vertical, eliminating the cracks that tend to occur during demolding of the deep water channel, and improving the aesthetics of the inner surface of the water channel.

４）台枠10上の端部に妻板支持専用の支柱15′を別に設
けたものは、製品中央部に継ぎ目も表れず、型枠構造が
簡単で低価格になり脱型も容易になり省力化が計れる効
果がある。4) In addition, a column 15 'dedicated to supporting the gable plate is additionally provided at the end on the underframe 10, and no seam appears at the center of the product, the formwork structure is simple, the cost is low, and demolding is easy and labor saving. There is an effect that can be measured.
