In the embodiment, it is formed in three places. Further, a magnet 17 is attached on the surface side of the end face mold 4 and on the surface side of the portion that comes into contact with the end side part of the inner mold form 3 formed in a substantially square shape. 3 can be connected.

  After the inner mold 3 and the end mold 4 are rotated by a predetermined angle, the outer mold 2 is rotated so that the magnets 17 on the rib member side of the end mold 4 are moved to the outer mold 2. It will be combined with the inner wall of.

As shown in FIG. 6 , the auxiliary mold 5 is disposed in the gap between the outer mold 2 and the inner mold 3 on the fixed base 6 a of the base. End side of the side, Figure 2, as shown in FIG. 3, as sandwiched between the outer mold 2, the lower portion of the inner mold 3 and the rotation support plate 7 and the two movable base 6b and both end faces formwork Arrange. The auxiliary mold 5 is a mold forming the lower end side of the U-shaped groove block W1.

  As shown in FIG. 6, the auxiliary mold 5 is divided into two at the substantially central portion thereof to form divided auxiliary members 5 a and 5 b, respectively. The upper end portions 5c and 5d of the respective outer end portions are pressed inward by the respective end face molds 4a and 4b. The upper end 5c protrudes outward and is formed as a protruding upper end 5c.

Further, a gap is formed between the ribs 5e and 5f that form the inner ends of the division assisting members 5a and 5b facing each other, and a communication rod 5g is disposed between the ribs 5e and 5f. A spring body 5h such as a leaf spring or a wire spring is inserted into the connecting rod 5g located in the gap in a loosely fitted state to prevent the spring body 5h from being displaced and at the same time divided into the left and right parts. The auxiliary members 5a and 5b are configured to cope with expansion and contraction. The spring body 5h urges the separation assisting members 5a and 5b away from each other.
Therefore, the auxiliary member 5 is biased in the direction in which the member length becomes longer.

When the U-shaped groove block W1 is manufactured, the inner mold 3 is inclined, so that the end face mold 4 is similarly inclined. As shown in FIG. 6 (b), the end face mold 4a rotates about a shaft 15 formed on the fixed base 6a side, so that it contacts the protruding upper end 5c of the split auxiliary member 5a. The contacted portion moves outward by an interval H1 due to the urging force of the spring body 5h.
On the other hand, as shown in FIG. 6 (c), the end face mold 4b has the shaft 16 raised by the rotation of the movable base 6b, and the shaft 16 formed at the end of the movable base 6b. Since it pivots about the center, the portion that contacts the upper end portion 5d of the division assisting member 5b is pushed by the end face mold 4b and moves inward by an interval H2.

Along with the inclination of the end face molds 4a and 4b, the auxiliary mold 5 becomes longer by the length corresponding to H1-H2. Therefore, the mold forming the lower end portion side of the U-shaped groove block W1 becomes long.
On the other hand, since the distance between the axes 15 and 16 does not change, the distance between the end face molds 4a and 4b is kept constant regardless of the inclination. Therefore, in the completed U-shaped groove block W1, as shown in FIG. 1B, the perpendicular interval between the front end W1c and the rear end W1d is constant, and the horizontal gap becomes longer.
A rail 6a1 is laid in the longitudinal direction on the fixed base 6a so that the auxiliary members 5a and 5b can move smoothly.

  When manufacturing the U-shaped groove block W of FIG. 1A, the upper surface plates 5i and 5j of the division assisting members 5a and 5b are in contact with or close to each other. However, when the U-shaped groove block W1 is manufactured, as described above, the member length of the auxiliary mold 5 increases with the inclination of the end face molds 4a and 4b, and the interval H3 increases. Become. Therefore, a member that closes the gap H3 is required.

The top surface plates 5i and 5j have end surfaces on the end surface side having protrusions 5k and 5l. By inserting the insertion material 5m from the side of the gap H3, the insertion material is inserted into the gap H3 without falling off. 5 m can be arranged. Depending on the degree of inclination of the auxiliary member 5, the width of the interval H <b> 3 varies depending on the degree of inclination of the auxiliary member 5.
Moreover, it can prevent that the water and mortar of the placed concrete member leak from the said location by providing a sealing material in the circumference | surroundings. Furthermore, it goes without saying that a sealing material is also formed at the end of the entire top plate 5i, 5j as necessary.

The forming mold 1 for manufacturing the U-shaped groove blocks W and W1 can be changed in the width direction and the height direction. In the case of the change in the width direction, the intermediate additional mold 18 is additionally disposed and fixed to the inner mold 3 and the end mold 4.
As shown in FIG. 8, the inner formwork 3 and the end face formwork 4 are composed of a basic formwork section L and a moving-side basic formwork section R, and the basic formwork section L and the moving-side basic formwork section. The insert additional mold 18 is inserted between R. As a result, an intermediate mold part M is formed as shown in FIG. In the case of the U-shaped groove blocks W and W1, the formwork that can form the minimum required width is the basic formwork part L and the movable basic formwork R. It is possible to cope by adding and fixing an appropriate number of additional molds 18.
In order to facilitate the movement in the width direction of the movement-side basic mold R, a rail 6a2 is laid along the movement direction on the fixed base 6a.

A fixed base 6a and a movable base 6b are additionally provided for the increase in the width direction. An additional base 19 is added to the intermediate portion and fixed in accordance with the increased width.
The additional connection for the change can be performed by a bolt or the like.
The lateral width S of the U-shaped groove blocks W, W1 can be changed by appropriately adding the inner mold 3, the end face mold 4, and the base 6. In addition to changing the form for manufacturing the U-shaped groove block W1 for installation on the inclined ground, the end form 4 added to the rotary push plates 13 and 14 by additionally arranging the inner form 3 on the added movable base 6b. It becomes possible by fixing

FIG. 9 shows a height change additional form 20 for changing the height of the U-shaped groove blocks W and W1. As shown in FIG. 2, the height changing additional mold 20 is stacked and fixed above the auxiliary mold 5. The heights of the U-shaped groove blocks W and W1 can be changed by preparing various parts having different heights and combining and fixing them.
2 shows a state in which the member (a) is stacked on the member (b) of the height change additional form 20 of FIG. Thereby, the height of the U-shaped groove blocks W and W1 is lowered by an amount corresponding to (a) + (b). The height of the U-shaped groove blocks W and W1 formed by the mold shown in FIG. 2 is reduced by 300 mm.
On the other hand, when the height is increased, each additional mold is added to the outer mold 2, the inner mold 3, and the end face mold 4.
