BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for manufacturing a plastic plate material.

[0002]

2. Description of the Related Art In recent years, a plate material made of a light-weight cellular concrete, which is a plastic material, has been widely used as the quality of a house becomes higher. In order to make the plastic plate material, a large number of reinforcing materials for plate materials are arranged and hung in the formwork, a plastic material rectangular matrix containing these is formed, the rectangular matrix is divided, and each of the above reinforcing materials is formed. Use a board material. 5, 6 and 7 are explanatory diagrams,
FIG. 5 shows a state in which a large number of plate reinforcing members 9 are arranged and hung on the mold 1 by a support mechanism (not shown).

Immediately before or after disposing the reinforcing material 9 in the mold as shown in FIG. 5, a slurry of a plastic material is poured. The slurry can be divided with a piano wire, but when it hardens so that it does not collapse even if it is removed from the mold, the side plates and end plates of the mold 1 are opened to expose the rectangular matrix 10 of the plastic material as shown in FIG. . The fact that the demolding work of the rectangular matrix 10 is troublesome can be understood by considering its size, weight, and the tendency to collapse like soft tofu. The size is usually 6 m in length, 1.5 m in width, 0.6 m in thickness, and weighs over 10 tons, and it is transferred on a transportation base plate so as not to collapse.

Then, the base plate is carefully moved so as to be attached to a predetermined position of a cutting device (not shown). Then, the vertical and horizontal piano wires for vertical cutting and horizontal cutting of the cutting device are moved vertically and horizontally. At that time, the base plate requires a troublesome mechanism to avoid the lower end support portion of the piano wire. When the group of the plastic plate materials 10a (see FIG. 7) is cut in the vertical and horizontal directions in this way, it is carried to the curing station mounted on the base plate 8, but at that time, it is more likely to collapse than the state of the large block 10. More mold release,
Transporting and cutting required extensive equipment and the careful attention of site workers.

[0005]

As described above, the large volume,
On-site work for demolding, transporting, and cutting a heavy-weight and fragile plastic material has been a cry of conventional technology. Nevertheless, in the eyes of conventional researchers, the material of the plastic material,
The efforts at the site have been overlooked because of the modeling and cutting. Or maybe it was thought that it could not be improved. The inventors of the present invention first considered reducing the labor of the site worker, but by solving this problem, it was possible to obtain a great improvement in terms of equipment and cost.

[0008]

The present invention has overturned the conventional fixed concept since the development of this type of manufacturing method: filling and shaping at the position of the mold, and dividing into plates at the position of the cutting device. That is, the material filled in the mold and half-solidified is divided into a required number of plate materials in the mold. In other words, the formwork that has been sculpted is
Change to that cutting equipment. Unlike the conventional case, even if a large lump with a large volume and a large weight that is fragile is not carried from the mold to the cutting device, it is located in the required position for cutting in the mold.

[0009] The filled and shaped plastic material rectangular matrix is used as a mold.
The dividing means with this device is the unique dividing tool of this invention.
This is a lifting frame, vertical material, piano wire (or plate blade, abbreviated below)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view of an embodiment of the present invention, in which a lifting / lowering drive mechanism for a divider is omitted . If those raised to true above hydraulic mechanism, thien winding mechanism or the like, because any elevation driving mechanism can be used, an abbreviation for looking difficultyゝnon to the drawings. The vertical members are not visible in FIG. In FIG. 1, 1 is a formwork, 1a
Is its side plate, 1b is an end plate, and 1c is a hinge. Rectangular shape frame placed on the upper edge inboard of the mold 1 is divided shown withdrawn in Figure 2
In the lifting frame 2 of the tool A , this lifting frame 2 includes four horizontal members 3, 3a.
Paste, its crosspiece 3,3a are is fixed hanging uprights 4, 4a. Reference numerals 5 and 5a are piano wires. Reference numeral 6 in FIG. 1 is a suspending jig for suspending three groups of reinforcing materials for plate materials, and the suspension jig is laid between the horizontal members 3 and 3. However, since the reinforcing material is not directly related to the present invention, it is depicted in FIG. Not in. In addition, the cross member 3 in FIG.
It was drawn as a fixed type instead of the hook type in which the interval can be adjusted like the horizontal member 3 of FIG.

In FIG. 2, the inner wall surface of the mold 1 on which the elevating frame 2 is mounted is shown by the chain line. The vertical member 4 of the divider, which plays a major role in the present invention, includes end plates (see FIG. 1) on both sides of the formwork.
1b) , the same number of vertical cut surfaces as the vertical cross section are hung from the horizontal member 3, and the same number of piano wires 5 are stretched between the lower ends of both sides, and the middle horizontal member above the boundary portion of the reinforcing member group is midway. It is supported by the lower end of the vertical member 7 for intermediate support which hangs from 3a at the crossing position of the vertical and horizontal cross sections . Only the both ends of the intermediate horizontal member 3a hang down the vertical member 4a along the form side plate 1a (FIG. 1) and stretch the horizontal cutting piano wire 5a. With this, the longitudinal direction can be divided into three. Since the two lateral piano wires 5a are short, it is not necessary to support them in the middle, but in this embodiment, all of the vertical members 7 hanging from the two intermediate horizontal members 3a are used for the vertical and horizontal cross sections , respectively. Both support the piano wires 5 and 5a.

FIG. 3 is a plan view of FIG. The vertical member 4 at the position along the mold end plate 1b in FIG. 1 is a round bar, and the vertical member 4a along the side plate 1a is a square bar, but of course, the shape is not limited. The vertical member 7 that supports the piano wire in the middle is a round bar. There is no problem because the vertical and horizontal piano wires 5 and 5a are simultaneously moved up and down by the elevating frame 2. However, if you do not always raise and lower all the piano wires at once, use a common rod 7
It is not possible to support in the middle.

FIG. 4 is an embodiment showing that, even if the lengths of the plastic plate materials to be manufactured are different, according to the present invention, each can be divided into required dimensions. That is, one of the two lateral piano wires 5a shown in FIG. 3 is shortened like a piano wire 5a 'shown in FIG. 4, and one of the intermediate supporting vertical members 7 is a vertical member for fixing the end of the piano wire. An example used as is is FIG. As a result, when the elevating frame 2 is pulled up, the four plate members are divided into lengths that are twice as long as the other plate members. Not limited to this embodiment, by appropriately changing the tension of the piano wires 5 and 5a, it is possible to obtain plate materials of various sizes all at once. It is unimaginable in the prior art that it is possible to easily make plate materials of different sizes all at once.

Although one embodiment has been described above, the present invention can be variously changed and applied by a well-known technique by a mechanical engineer without changing the gist thereof. For example, a vertical material with a piano wire moves up and down along the inner wall of the mold,
If the vertical material is guided by providing a dovetail-shaped guide groove on the inner wall surface, the piano wire can be installed with sufficient tension, so intermediate support is not necessary or reduced, and a guide mechanism for vertically elevating the vertical material is additionally provided. Even if it does not exist, the formwork itself becomes the guide mechanism for cutting. If you add the necessary auxiliary guide materials on the form,
Vertical cranes can be lifted and lowered with a simple crane or hoist. Further, in the above embodiment, one vertical member is provided at each end for each piano wire, but the vertical member is not a rod but a flat plate that fits along the form plate end plate and slides up and down. Of the vertical piano wire of Fig. 2 or 3, the intermediate vertical member 4a, the intermediate supporting vertical member 7 and the piano wire 5a.
It is easily conceivable to replace with a single flat plate (which becomes a partition plate). The piano wire and the plate blade may not be put in the mold in advance, and may be lowered from the top after modeling.

[0015]

As described above, the present invention has opened a way for a formwork, which is a molding facility, to also serve as a cutting device, which is a cutting facility. Since modeling and cutting are performed in the same mold, it is difficult to perform on-site work for demolding, moving, and cutting a conventional plastic rectangular parallelepiped that has a large volume and a large weight, and conventional large-scale equipment therefor. Made unnecessary. Since the inner wall of the mold has the function of preventing the plastic plate material from collapsing during cutting, and also guiding the accurate up and down movement of the piano wire, the mold and cutting device that realize the concept of cutting in the mold of the present invention are integrated. It was easier than I expected, and it became the simplest facility for plastic plate manufacturing.
