DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turning device for a formwork, and more particularly to a fixing device and an automatic demounting device for a turning device for a formwork used for manufacturing lightweight cellular concrete using a foaming agent.

[0002]

2. Description of the Related Art As shown in FIG. 5, a formwork used for the production of lightweight cellular concrete includes a swivel partition plate 1 which is rotatably fixed to a steel bottom plate 4 and side plates 3 on both sides thereof.
And a movable partition plate 2 that can be moved and fixed. A reinforced mat 20 is suspended in a set frame 19 supported by the side plate 3 in the formwork, and a raw material slurry for lightweight cellular concrete containing a foaming agent is poured into the formwork to manufacture an ALC plate. At this time, since the foaming agent is contained in the slurry, the pressure due to the expansion acts on the swirling partition plate 1 as well as the movable partition plate 2 from the lateral direction. Therefore, the swirling partition plate 1 also needs to be firmly fixed, and after the foaming is completed, it is necessary to swivel the swiveling partition plate to remove the product from the product. A conventional method of fixing the revolving partition plate 1 uses a commercially available pull clamp. After the hook 16 is hooked on the hook bar 17 of the side plate 3 as shown in FIG. It was a method of fixing. That is, the pulling clamp body 26 is rotatable about the pivot point 27 by the lever 18, and the hook 16 is provided on the body 26 so as to be able to move in and out, and is received by the stopper 28 of the body to pull the hook 16. Spring 2 biasing
9 is provided on the hook 16. Therefore, when the handle 18 is turned upward by 180 ° from the state shown in the figure,
Since the distance between the stopper 28 and the hook bar 17 is shortened and the pulling force of the spring 29 does not act on the hook 17, the hook 16 comes off the hook bar 17. Conversely, when the lever 18 is turned downward, the spring 29 works to fix the hook bar 17 with the hook 16.

[0003]

The above-described conventional method of fixing the turning partition plate of the formwork can be performed only by manual operation, and is not a method of automatically attaching and detaching in combination with an automatic attaching and detaching apparatus, and is difficult to attach and detach. And took more effort and time. An object of the present invention is to provide a fixing device and an automatic desorption device of a form turning partition plate that can securely fix the turning partition plate even when pressure due to expansion of the raw material slurry is applied and that can automatically attach and detach the turning partition plate. I do.

When the cylinder is stopped after pushing the mounting shaft with one pusher of the cylinder in the automatic release device from the fixed state and pressing the release lever with the other pusher in the automatic release device, the hook member is released from the rack member. Then, the fallen hook member is hooked on the upper part of the turning partition plate, and the hook of the pool frame member that raises or turns the turning partition plate defeats the turning partition plate and separates from the product.

An embodiment shown in the drawings will be described below.
First, a description will be given of the turning partition plate fixing device A. As shown in FIG. 1, hooks 5 are swingably provided on both sides of the revolving partition plate 1, and are capable of engaging and disengaging with a rack 10 of the formwork side plate 3. A rotary spring 7 is stretched between the hook 5 and the frame of the revolving partition plate 1 to urge the hook in the direction of engagement with the rack. The mounting shaft 8 is provided on the frame of the revolving partition plate 1 so as to be able to move forward and backward, and is urged in the backward direction by a tension spring 9. The hook 5 is supported on the mounting shaft 8 by a hinge pin 8a.
The release lever 6 that swings the hook in the release direction is provided integrally with the hook 5.

When the hook 5 pushes the mounting shaft 8, the hook 5 moves forward and is rotated by the rotary spring 7 so as to be hooked on the rack 10 mounted on the side plate 3.
When the pressing of the mounting shaft 8 is stopped, the hook 5 is pulled by the tension spring 9 and the turning partition plate 1 is fixed. Conversely, when the mounting shaft 8 is pressed from the fixed state and the pressing of the mounting shaft 8 is stopped while pressing the release lever 6, the hook 5
