(Conventional technology) Conventionally, concrete panels for OA floors, etc.
A surface plate 24 is installed on a workbench 23 as shown in FIG. 7, and frame edges 25 as shown in FIG. Mortar is poured into the inside, the surface is finished with a trowel 4 to 5 times, and after the mortar has hardened, the frame edge 25 is
It is manufactured by flat hammering, which is transferred to a workbench 27 as shown in the figure, and subjected to finishing to obtain a product.

(Problem to be solved by the invention) In the above-described flat manufacturing of panels, the surface of the product is not molded, so the flatness and smoothness of this part are poor. Therefore, the surface is finished with a trowel to improve the flatness. and smoothness must be satisfied,
Furthermore, since the edges of the frame are arranged flat, the space occupied by the frame becomes large, resulting in the problem that only a small amount of products can be manufactured even in a large work area.

The present invention was made in order to solve the above-mentioned conventional problems, and the required number of vertical frames with frame edges accommodated in the side frames are held vertically in a holding means, and each frame edge is Adopting vertical casting, in which the material is driven from above, the surface of the product is also molded, achieving good flatness and smoothness that does not require troweling, and the vertical arrangement of frame edges saves a large amount of space. It is an object of the present invention to provide a concrete panel manufacturing apparatus that enables mass production of products in a small space by reducing the amount of energy required.

B. Structure of the invention (means for solving the problem) The means of the invention for achieving the above-mentioned object consists of a frame edge formed of a thin plate and having a hole for driving material in the upper part, and a frame edge that is A vertical frame with a smooth face plate on both sides attached to one of the side frames to be accommodated, and the required number of vertical frames are lined up vertically, and both openings of the edge of the frame accommodated in each frame are connected to the smooth surface of the adjacent vertical frame. The concrete panel manufacturing apparatus is provided with a holding means that is held so as to be closed by a face plate.

(Function) The manufacturing apparatus of the present invention configured as described above has the following features:
As shown in Fig. 1, the frame edge is formed of a thin plate and has a hole for driving material in the upper part, and as shown in Fig. 2, a side frame with an open top is attached to one side of a face plate whose both sides are smooth. As shown in FIG. 4, these vertical frames are placed in the side frames of the vertical frames formed by the above method, and when these vertical frames are lined up between the two clamping plates of the holding means and the lower part of one side is pressed against the ruler plate, 1. A large number of vertical frames are neatly held within the holding means, which has a small space with two frame edges laid flat. When the movable side of the frame is pushed forward, each vertical frame is sandwiched between the movable and fixed clamping discs and brought into close contact with each other, and one opening of each frame edge accommodated in the side frame of each vertical frame is closed by the face plate of the vertical frame that accommodates it, and the other opening is closed by the face plate of the adjacent vertical frame. Then, the movable pincher is stopped and the material is driven into each frame edge through the holes provided at the top of the frame edge.The material fills the frame edge, which is supported on the outside by the side frames, and covers both surfaces. Since molding is performed using a smooth face plate, a product with good flatness accuracy and smoothness is completed. Once the completed product has solidified to a state where it can be removed from the mold, the nut is rotated in the backward direction, the movable clamping plate is moved away, each vertical form is untightened, and each vertical form is removed from the holding means. If you take out the panel with the frame edge from the side frame of this vertical frame, the surface has good flatness and smoothness, so you can create a product panel that does not require troweling, but in the space of one conventional flat panel. It can be manufactured in large numbers in the industry.

(Example) An example of a concrete panel manufacturing apparatus related to the present invention will be described below based on the drawings.

Figure 1 of the drawing shows the frame edge 1.
is formed using a thin plate material such as SUS into a shape that matches the peripheral edge of the product panel, one of the openings is chamfered as necessary, and a hole is formed in the center of the upper edge into which material is driven. 3 is opened, and holes 4, 4 are provided at both ends to vent air within the frame edge 1 when driving the material.

2 and 3 of the drawings show a vertical frame 5, in which a side frame 7 accommodates the frame edge 1 on one side of a face plate 6 whose both sides are smooth and is supported so as to withstand molding pressure. The side frame 7 of the vertical frame 5 is opened upward as shown in FIG. Since the frame edge 1 is not supported in this area, the frame edge 1 may be deformed. In this case, as shown in FIG. .

5 and 6 show the holding means 8 for the vertical frame 5 described above, and this means 8 has fixed and movable clamping plates 10 and 11 on one side and the other side of the base frame 9. When the required number of vertical frames 5 are arranged vertically between the two and the lower part of one side of these vertical frames 5 is pressed against the ruler plate 12 attached to the base frame 9, the vertical frames 5 are aligned. It is made to align accurately.

Reference numerals 13 and 13 denote tightening screws for each vertical frame 5 arranged on both sides of the above-mentioned holding means, the base side of which is supported by a U-shaped bracket 14 attached to a fixed clamping board 10, and the screws on the tip side The part is supported by a U-shaped receiver 15 attached to a movable clamping board 11, and a nut 16 with a handle is screwed onto the part that protrudes outside, and the movable clamping board is formed by rotating this nut 16 in the direction of movement. 1
1 to the fixed clamping plate 10 side, each vertical frame 5 is clamped by both clamping plates 10 and 11, and the opening of the frame edge 1 accommodated in these side frames 7 is opened to the vertical frame. The product 17 is closed by the face plate 6 of No. 5, and the molding of the product 17 by pouring mortar is performed by molding the face plate 6, so that the plane accuracy and smoothness are good.

Reference numeral 18 denotes a pedestal for the above-mentioned holding means, and a support shaft 19 is horizontally mounted at a position slightly biased to the rear side from the center of the pedestal.
By engaging this support shaft 19 with the chevron-shaped groove 20 provided at the lower part of the base frame 9 of the holding means 8, when the stop member 21 sandwiched between the base frame 9 and the pedestal 18 is removed, the holding means 8 is inclined as shown by the chain line in FIG. 5 to facilitate the insertion and removal of the vertical frame 5 into the holding means 8, and when the insertion of the vertical frame 5 is finished, the holding means 8 is tilted as shown in FIG. Return it to the horizontal position as shown by the solid line, and insert the stopper member 21 between the base frame 9 and the pedestal 18 to fix the holding means 8 in a horizontal state so that material can be easily driven into the frame edge 1. This is what I did.

Incidentally, reference numeral 22 denotes an auxiliary face plate attached to the movable clamping board 11, which is designed to close off the open side of the last vertical frame 5.

500 x 500 x 20 mm using the device shown in the previous example
manufactured OA floors.

As a result, the surface of the product floor is molded by the face plate 6 of the vertical formwork 5, so it has good flatness and smoothness, and there is no need for trowel finishing.
Since the holding means 8 of the vertical frame 5 can hold 20 vertical frames in the area occupied by one product floor,
Compared to conventional four-piece flat molding, the work space is reduced to 1/4, but the manufacturing capacity is increased five times.

C. Effects of the invention Since the concrete panel manufacturing apparatus according to the invention performs pouring of material by closing both openings in the frame edge with the face plates of the vertical form, the surface of the manufactured panel has good flatness accuracy due to molding. It has smoothness and does not require finishing with a trowel, which saves time and effort for finishing.

The vertical frame containing the frame edge is supported vertically on the holding means, and the material is vertically stamped into the frame edge, making it possible to manufacture a large number of panels in the space equivalent to one flat panel. This has unique effects such as reducing the work area and increasing manufacturing capacity.
