In addition, left and right latches 17.17 are provided on both the left and right sides of the form frame, with their base ends pivoted, and when the front form frame is erected and closed as described above, the left and right latches 17.17 are The front form frame can be fixed by rotating and engaging the window holes 18 in the left and right side walls of the frame 1, respectively.

That is, each of the above-mentioned clamp tools 15, each ring bar 16, and the left and right latch 1
7 and the left and right window holes 18 constitute a clamping device K for tightening and fixing the respective formworks to each other.

Furthermore, leg rods 19 are provided on both the left and right sides of the rear rear of the frame 1, with their base ends pivoted, and by raising the left and right leg rods 19 by foot operation, the frame 1 can be raised to a high slope at the rear. It is designed to be held in place.

The above is the configuration of the forming frame device of this invention. Next, we will explain the case of manufacturing the earth retaining concrete block 20 using this device using the drawings. First, from the state shown in Figure 7A of the drawing, On the other hand, the left and right formworks B, B, the rear formwork C, and the front formwork are respectively rotated upright and closed, and each of the clamping tools 15 and the left and right latches 17, 17 are operated respectively to tighten the above-mentioned formworks together. Insert 1 into the lower formwork A a reinforcement framework 26 that has been prepared and placed in advance in the same way as the secondary part to be fixed.

Next, concrete is poured into the lower form A from the inside of the vertical form 4 to the inside of the concave part 8 and onto the floor plate 2, and each form is vibrated by a vibrator.

(ibid. c). Then, after the concrete has spread to every corner of the vertical frame part 4, the recessed part 8, and the floor plate part 2, and the concrete thickness on the floor plate part 2 is made to a predetermined thickness, the surface layer is decorated as appropriate. Finish by adding stones.

Then, as in the second example, the left and right leg rods 19 are erected, the frame 1 is held in an inclined manner, and the frame 1 is washed with water to finish the surface.

Once this is completed, the poured concrete is cured using steam curing.

When this curing is completed, the clamping device K is released and the front formwork is removed, and the left and right formworks 9B and the rear formwork C are opened, and the molded parts in the lower formwork A are opened as shown in E. Vertical of the concrete block 20: The lower end of the leveling plate 21 is the pillow stand 27
Stand up frame 1 so that it rests on top of it.

Then, by performing the bundle operation of the screw shaft 14, the movable plate 8
By pushing forward, the reaction force will push the lower formwork A backward together with the frame 1, and this action will push the lower formwork A, which is integrated with the frame 1, into the concrete block 20.
After being detached, frame 1
Return it to its original state.

Concrete blocks 20 are sequentially manufactured in the manner described above, and are stacked and aligned in the same manner.

In the above drawing example, the surface of the vertically leveled plate 21 of the concrete block 20 formed in the floor plate portion 2 of the lower formwork A is finished with decorative stone, but other materials such as tiles or bricks may be used. Various surface finishes such as finishing can be selectively performed.

As explained above, the forming frame device of this invention includes a lower formwork A integrated with a frame 1, left and right formworks B, B and rear formwork C that can be opened and closed respectively, and a front formwork that is removable and removable. Because it consists of a formwork, concrete can be poured all at once, and forming concrete blocks and taking out molded products can be done efficiently and efficiently. Since the vertical adjustment plate 21 of No. 20 is molded on the floor plate section 2 which is opened at the top of the lower formwork A attached to the upper end of the frame 1, its outer surface is adjusted to the desired thickness. It can be easily applied to a wide variety of surface finishes, such as polished or polished finishes with decorative stone, or tiled or bricked finishes, and has excellent effects.

In addition, in the above, since the leg rods 19 are provided to hold the rear part of the frame 1 in a high and inclined shape, the frame 1
Washing with water is carried out by slanting the
The through hole 13 provided in the bottom of the reinforcing rib concave portion 8 has the effect of allowing the polishing and finishing work to be performed rationally and easily.
