Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a concrete panel manufacturing apparatus for manufacturing concrete panels for buildings such as houses and buildings.

(Prior Art) Recently, in the construction of houses, buildings, etc., a construction method has been adopted in which concrete panels are manufactured in advance and the panels are assembled at the construction site. Various types of concrete panels are manufactured, including panels for exterior walls, floors, partition walls, and ceilings.

FIG. 6 shows a concrete panel manufacturing apparatus. A frame plate 1.2.3.4 is arranged in a rectangular shape on the upper surface of the metal plate base 10, and a mold is formed inside the frame plate 1.2.3.4. A jig 5.6 is attached to the frame plate, for example 3.

The jig 5.6 is for temporarily fixing the end of the conduit or the connector connecting the conduit and the jig in order to bury the conduit or the like inside the concrete panel.

Furthermore, a jig A7 for temporarily fixing the electrical box is also attached to the metal plate base 10 in order to pull out the terminal of the electric wire or attach a switch.

FIG. 7 is a sectional view showing a portion of the jig 5.

The jig 5 has a bolt portion 5a, a head 5b, and a nut 5c, and is attached with the head 5b facing inside the frame plate 3, as shown in FIG. 5(b). When concrete is cast inside the frame board 3, the end of the electric conduit 8 is connected to the head 5b via the connector 9, as shown in FIG. 3(C). In this way, the necessary parts are arranged inside the formwork,
Concrete 11 is placed as shown in FIG. 8(a). When the concrete 11 hardens, the frame plate 3 is removed from the metal plate base 10, as shown in FIG. 8(b). Although only the frame plate 3 is shown in the drawing, in reality it is necessary to remove all the frame plates shown in FIG. When the frame plate is removed, concrete 11 remains on the metal plate base 10, which is taken out with a crane or the like and used as a product.

(Problems to be Solved by the Invention) According to the conventional manufacturing apparatus described above, when the concrete panel is finally taken out, it is necessary to remove all the frame plates from the metal plate base 10. This removal work is very labor intensive and time consuming. In particular, the frame plate is a metal plate and has a large weight, which increases the risk of accidents during work.

Further, the work of removing the frame board also requires skill, and if an inexperienced person performs the work, the corners of the concrete panel may be damaged. Additionally, if the frame plate is edited many times, the screw holes in the metal plate base may become damaged or clogged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a concrete panel manufacturing apparatus that does not require the removal of frame plates and can significantly improve workability.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a method in which a jig for forming a recess on a side surface of concrete is placed in a state in which it penetrates a frame and protrudes inward, or in a state in which it is retracted. A jig control mechanism for controlling the jig is provided in the frame.

(Function) By using the above method, the jig is made to protrude inside the frame when concrete is poured, and after the concrete has hardened, the jig is retracted. This allows the concrete panel to be lifted out of the formwork as is. In other words, there is no need to remove the frame from the base, and work efficiency can be greatly improved. Furthermore, by providing the jig and its control mechanism, various advantages described below can be obtained all at once.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Reference numeral 20 denotes a metal plate base, and a frame plate 21 constituting a formwork for obtaining a concrete panel is attached to the upper surface of this base 20. This frame plate 21 is firmly fixed to the base 20 in advance by, for example, welding or screws.

An opening 22 is formed in a part of the frame plate 21, and this opening 22
One end of a guide tube 23 is attached to the outer surface of the guide tube 23 coaxially with the opening. A jig 25 is coaxially disposed inside this guide tube 23.
has been inserted. The head 25a of the jig 25 has the opening 22
A bolt 26 is integrated into the proximal end portion facing the side. Further, a thread is formed on the inner circumferential surface of the guide tube 23 to correspond to the bolt 26, and when the bolt 26 is rotated, the jig 25 can be moved between a state in which it is protruded from the opening 22 and a state in which it is retracted. Obtainable. The figure shows the jig 25 in a retracted state. Furthermore, the end of the bolt 26 (the guide tube 23
A handle 27 is attached via a rotary plate to the outside of the handle 27 and can drive the bolt 26. guide tube 23,
The bolt 26, handle 27, etc. constitute a jig control mechanism.

This embodiment is constructed as described above.

FIG. 2 shows an example of the use of the above device.

FIG. 2A shows the state before concrete is poured, and the jig 25 can be made to protrude inside the frame board 21 by operating the handle 27. In the same figure (b), the jig 25 is made to protrude and the conduit 31 is connected to the jig 25 via the connector 30.
This is the state in which the end of the pipe is attached and the concrete is poured.

The conduit 31 is arranged corresponding to the place where the concrete panel is used, for example, an indoor wiring location such as a wall, ceiling, or floor of a building.

FIG. 2(C) shows the state after the concrete has hardened and before it is removed from the formwork. Previously, at this stage, all the frame plates would be removed and the concrete panel would be lifted from the base and removed. However, according to the present invention, there is no need to remove the frame plate, and the jig 25, which would be a hindrance to lifting the concrete panel, is retracted by the control mechanism and is not locked to the concrete panel. Therefore, the concrete panel can be pulled up while leaving the formwork as it is. To pull up a concrete panel, for example, a lifting wire or the like can be buried in the concrete panel, and a crane hook can be locked there and pulled up.

In the above-mentioned embodiment, the jig control mechanism has the basic structure of the relationship between bolts and nuts, but the present invention is not limited to this.

FIG. 3 shows another embodiment of the jig control mechanism.

In FIG. 4A, a jig 41 that allows the piston to move is inserted into the guide tube 23, and the jig 41 can be driven from the outside by a lever 42. The lever 42 is rotatably supported by a support portion 43 fixed to the outer surface of the frame plate 21, and one end is rotatably attached to the end of the jig 41. Therefore, lever 4
By operating the other end of the jig 41, the jig 41 can be in a state of protruding into the inside of the frame board 21 or a state of being retracted from the inside of the frame board 21.

FIG. 3(b) shows an embodiment in which the jig 45 is controlled by an air cylinder or a hydraulic cylinder 46.

As described above, according to this apparatus, a concrete panel can be manufactured without removing the frame board from the base. Note that the shape of the guide cylinder is not limited to a cylindrical shape, and various shapes can be used.

When this device is used, as shown in FIG. 4, a concrete panel production line can be automated.

In other words, jig punching process A1, parts mounting process A2,
The concrete placing process A3, the drying process A4, the jig pulling process A5, and the concrete panel dispensing process A6 can be arranged in this order.

Igo Process AI & is a process in which the jig is made to protrude inside the frame.

Step A2 is a step of attaching electrical conduits and the like. Drying process A4 is a process of curing concrete.

FIG. 5 shows another embodiment of the invention.

In the above embodiment, a jig was used for temporarily fixing electric conduits and the like. However, as shown in Figure (a), concrete panels do not necessarily have flat sides because they are connected to other panels. Rather, uneven surfaces and stepped portions are formed.

Further, a cutout portion 61 is formed as a draw-out portion of the low electric conduit. In order to form this cut portion 61, a colander X is placed inside the frame board 2, as shown in FIG. 2(b). The present invention can also be applied to such a case, and as shown in FIG.
It may be controlled by a control mechanism as shown in d). The control mechanism includes, for example, a bolt 64 and a handle 65 for driving the bolt 64. The tip of the bolt 64 is rotatably attached to the bolt 63, and the other end is passed through a threaded portion 66 at a fixed position. Thereby, by operating the handle 65, the entire cotter can be protruded or retracted into the inside of the frame board 61.

[Effects of the Invention] As explained above, according to the present invention, it is possible to provide a concrete panel manufacturing apparatus that does not require the removal of frame plates and can significantly improve workability.
