【Example】

 Hereinafter, the form supporting device for manufacturing the precast concrete material according to the present invention will be described in more detail with reference to the embodiments shown in the drawings. 1 and 2 show a form supporting device 10 for manufacturing a precast concrete material according to an embodiment of the present invention.

The form supporting device 10 for manufacturing the precast concrete material according to this embodiment is a rail member arranged and fixed on the H steel 11 arranged in parallel at a distance. That is, the gantry 12 is included. On the rail member 12, a pair of mold frame support body 13 is arranged.

Each of the pair of formwork support main bodies 13 includes a cover-shaped slider 14 slidably attached to the rail member 12, and a mounting leg 15 is provided on an upper surface of one end of the slider 14. It is erected. Frame mounting plates 16 are arranged on both sides of the mounting leg 15 so as to sandwich the mounting leg 15 at one end side, and are pivotally mounted by pins 17.

Further, a frame support frame 18 is sandwiched and fixed to the other end sides of the both frame attachment plates 16. As a result, the formwork support frame 18 is rotated by pivotal movement about the pin 17 of the frame attachment plate 16 as a rotation axis. As shown in FIG. 1, the pair of mold frame supporting portion main bodies 13 configured as described above are arranged by mounting the sliders 14 on the rail members 12 so that the mold frame supporting frames 18 face each other.

The space between the mold supporting frames 18 facing each other of the pair of mold supporting bodies 13 is set so that one or both of the mold supporting bodies 13 are slid on the rail member 12 so as to be spaced apart from each other. Will be adjusted accordingly.

When the position of each mold support main body 13 is determined, the bolts 19 provided on both sides of the slider 14 are rotated so that the tips of the bolts 19 are brought into contact with the side surfaces of the rail member 12 and tightened. Then, the slider 14 is fixed to the rail member 12. From that meaning, the bolt 18 functions as a stopping means.

It should be noted that the pair of mold frame support parts 13 are connected by fastening screw rods 21 in order to stabilize the intervals of the upper ends of the respective mold frame support frames 18. That is, as is clear from FIG. 2, a notch 20 is formed at the upper end of each form supporting frame 18, and the notches 20 pass through the fastening screw rods 21 as shown in FIG. The upper ends of the formwork support frames are connected by bridging between the support frames 18 and screwing nuts 22 on both ends, thereby preventing the formwork support frames 18 from being warped to the outside. There is.

The formwork supporting device 10 for producing a precast concrete material thus configured is used as follows. A plurality of the frame support devices 10 are arranged on the two H steels 11 with a predetermined interval. Then, depending on the width dimension of the precast concrete material to be manufactured, the mutual interval of the pair of mold frame support body 13 is adjusted by sliding one or both of them on the rail member 12 as described above.

As in the case of the conventional mold supporting apparatus 1 shown in FIG. 4, the mold supporting frames 18 of the pair of mold supporting body 13 of the pair of mold supporting bodies 13 adjusted to have proper mutual intervals are provided with the molds. The side panels 6a constituting the frame 6 are arranged by utilizing the crosspiece 7 so as to extend in the arrangement direction of the form supporting device 10.

Further, the bottom panel 6 b is similarly arranged and fixed on the frame supporting frames 18 of the respective frame supporting devices 10 using the square pipes 8 so as to bridge the rail members 12. Has been done. In short, the long mold 6 having a U-shaped cross section is supported by each mold supporting device 10 at several positions in the longitudinal direction. After that, reinforcing bars are installed in the mold 6 and concrete is poured.

After a predetermined curing period, a precast concrete material (not shown) is removed from the mold 6. At the time of demolding at this time, as shown in FIG. 3, the frame mounting plate 16 is pivoted outward together with the frame support frame 18 to open the side panels 6a of the frame 6 to the outside.

In the formwork supporting device 10 for manufacturing the precast concrete material according to this embodiment, one or both of the pair of formwork supporting part main bodies 13 can slide on the rail member 12. Even when precast concrete with different width dimensions is formed, it can be used in common by adjusting the position.

Therefore, it is not necessary to use many types of form supporting body, and the manufacturing cost of precast concrete can be reduced. In the above-described embodiment, both the pair of mold frame support body 13 are slidable on the rail member 12 by the slider 14, but the slider 14 is provided on only one of the molds and the other mold is used. In the support portion main body 13, the mounting legs 15 may be directly attached to the rail member 12.

As described above, in the formwork supporting apparatus for manufacturing the precast concrete material according to the present embodiment, when the semi-precast beam is demolded from the formwork supported by the formwork supporting frame, The demolding work is very simple because the side panel fixed to this is pivoted and the side panel fixed to this is opened outward.

In the formwork supporting device for manufacturing the precast concrete material in the above-mentioned embodiment, the pair of formwork supporting body 13 is capable of sliding the rail member 12 by the slider 14. It goes without saying that the present invention has the same effect even when the formwork support frame does not move with respect to the rail member, that is, when the formwork support frame 18 is directly pivotally attached to the rail member.

[0028]
