程で製品を取出す。 When manufacturing an underdrain using the above formwork device, the first step is to disassemble the outer frame, clean it, and apply a mold release agent, and also clean the inner frame and apply a mold release agent. . Next, in the second step, reinforcing bars are set in the outer frame, in the third step the outer frame is assembled, and in the fourth step, the inner frame is set in a reduced state. 4th in the split type inner frame
The process is performed in two parts. After this, in the fifth step, the inner frame is expanded, and in the sixth step, concrete is poured, compacted, and cured. After the curing is completed, the seventh
In the step, the inner frame is reduced in size, and in the eighth step, the inner frame is pulled out.
In the case of a split type inner frame, the eighth step is performed in two steps. After that, the outer frame is disassembled in the 9th process, and the product is taken out in the 10th process.

た。 As mentioned above, conventional formwork equipment has the problem of a large number of steps. In addition, a temporary storage space for the pulled-out inner frame (almost the same space as the installation space for the outer frame) is required, and the inner frame may be damaged because temporary storage spaces are often used on dirt floors. There was a fear that it would happen. If the inner frame is damaged, there is a problem that not only is it difficult to pull out the product in the eighth step, but also the accuracy of the product is reduced. Furthermore, the second
In the process, the inner frame was inserted after reinforcing bars were set on the outer frame, so there was a problem that it took time to insert the inner frame.

する。 First, in the first step, the outer frame 2 and inner frame 3 are cleaned in the state shown in FIG. 4, and a release agent is applied. Next, in the second step, the support rod 11 is slightly lifted with a crane or the like and moved to the right side in FIG.
In the state shown in the figure, the inner frame 3 is reduced and a reinforcing bar is set between the outer frame 2 and the inner frame 3 from one end side of the frame 1 (the left side in FIGS. 1 and 4). At this time, the lock mechanism 18 is automatically activated by the weight of the lock handle 19, and the inner frame 3 is supported horizontally by the support rods 11 without moving, so that the reinforcing bars can be set smoothly. After this, in the third step, the front and rear side plates 5, 6 and the left and right side plates 7, 8 are raised and locked to assemble the outer frame 2, and in the fourth step, the inner frame 3 is expanded,
In the fifth step, concrete is poured, compacted, and cured.

返される。 After curing is completed, the inner frame 3 is reduced in the sixth step, the lock handle 19 is lifted horizontally to release the lock mechanism 18, and the front and rear side plates 5, 6 are removed in the seventh step.
The left and right side plates 7 and 8 are pushed outward, the outer frame 2 is disassembled, and in the eighth step, the product is lifted up a little by a vacuum or a clamping mechanism and pulled out to the left side in FIG.
At this time, as the product is pulled out, the support rod 1
1. The inner frame 3 advances from the state shown in FIG. 1 to the state shown in FIG. 4, and with this advancement, the support rod 1
1. Since the inner frame 3 moves above ΔH and a space is created between the product and the bottom plate 4 of the outer frame 2, the product can be easily pulled out. Then, the process is repeated again from the first step.

述と逆の作用で行なわれる。 First, in order to contract the expanded state shown in FIG. 5, the center screw 24a of the jack 24 is turned in one direction to draw the connecting rods 25 inward. Then, the upper parts of both side plates 3a are drawn together, and the upper end locking protrusion 3a1 of both side plates 3a is attached to the shoulder part 3.
b 3 is disengaged from the locking stepped portion 3b 1 and is stopped in a state where it hits the stopper 3b 2 . Then the upper plate 3b
The lower end inclined surface of the shoulder portion 3b3 slides on the upper end inclined surface of the side plate 3a and descends somewhat due to its own weight, resulting in the reduced state shown in FIG. In this reduced state, both side plates 3a
Also, on the outside of the upper plate 3b, gaps corresponding to the widths m and n are created compared to when the upper plate 3b is expanded as shown in FIG. 5, making it easier to set reinforcing bars and take out concrete products as described above. On the other hand, in order to expand the inner frame 3 from the contracted state, the center screw 24a of the jack 24 is turned in the opposite direction to push out the connecting rod 25, thereby performing an operation opposite to that described above.

As explained above, according to the present invention, the outer frame is provided on the frame so that it can be disassembled and assembled, and the inner frame is moved up and down, front and back in parallel to the frame via a support mechanism so as to be located within the outer frame. Since it is installed so that it can be moved, the process of setting and pulling out the inner frame can be omitted, reducing the number of processes, and there is no need for temporary storage space for the inner frame, making it easier to install the entire formwork device. The space can be reduced, and damage to the inner frame can be minimized since the inner frame is not placed on a dirt floor, etc., and the product can be easily pulled out and the accuracy of the product can be improved.
