Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for producing a long decorative concrete panel having hollow through holes.

[0002]

2. Description of the Prior Art Conventionally long concrete panels are as follows: 1) Inject soft-mixed concrete into a formwork and add a vibrating part to this to supply a material to be a cosmetic material to the upper surface or the lower surface of the formwork. And mold and cure.

2) A concrete loader that moves on a long floor is used to supply a concrete material having a fairly high hardness, and vibration is applied to the concrete material from above to compact it. The hollow portion is formed by a strained wire as the concrete loader moves. There is a method in which a moving core is formed by pulling out, after curing, cut into a fixed size, and a makeup process such as painting is performed in a later step.

[0004]

In order to manufacture a long concrete panel as described above, a vast floor area is required for molding and arranging the molded products on a flat surface on the floor for molding and drying. Since a coating resin or cosmetic mortar application step is added, a crane device is required to disperse pigments and liquid materials to stain other equipment and products and to treat the products after drying, resulting in enormous capital investment.

For this reason, there is a demand for the development of an efficient concentrated production technique for long concrete panels. However, the present invention has the above problems due to the method of simultaneously forming a decorative surface on the panel upper surface on a conveyor line. The present invention aims to solve the above-mentioned problems and also to apply the decorative surface of the concrete panel to solve the problem of hygroscopicity which is a defect of the concrete panel.

[0006]

The structure of the present invention for solving the above problems is a concrete panel manufacturing method and a concrete panel manufacturing apparatus as set forth in the claims.

That is, according to the present invention, a pallet is continuously fed onto a conveyor, concrete material is supplied to the pallet, and the concrete material is vibrated and pressed by rolling frames from both sides and from above. Hollow holes are formed in the concrete material by the simultaneously rotating spiral core rod. After being molded into a panel shape by this molding part, a cosmetic mortar or a moistureproof agent is applied to the upper surface and the molded body is cut according to the length of the pallet. A method for manufacturing a concrete panel by continuous rolling characterized by this series of manufacturing processes, and an apparatus for realizing such a method.

In this apparatus, a concrete material supplying device for continuously supplying concrete material onto a pallet continuously fed on a conveyor, a molding section for vibrating the supplied concrete material under pressure, and a concrete material for supplying concrete material. A rotating spiral core rod that forms a hollow hole, a device that continuously supplies and coats decorative mortar material, etc. on the upper surface that is roll-molded, and cuts the molding material into the same length as the pallet along with the conveyor and in the same cavern. A cutting device, including the above.

[0009]

In order to intensively form a long concrete panel having a decorative surface, the present invention continuously vibrates and pressurizes a long concrete panel by a fixed molding machine,
Since this is cut appropriately according to the length of the pallet and then transferred to the curing and curing room for curing, there is no need for a vast factory site and there is only one molding, and product color and quality control Will also be easier.

An embodiment will be described with reference to the drawings.

1) FIG. 1 is a front view of an apparatus for carrying out the present invention, and FIG. 2 is a plan view. Roller conveyor 2,
The pallet 1 having a constant length is continuously sent out at a constant speed by 2 and the concrete material is supplied from the hopper-shaped concrete material supplying device 3 into the forming section 4 on the pallet. Molding part 4 (details will be described later in 2)}
Then, the vibration pressure-molded molded body 5 is further advanced, and cosmetic mortar supplied from the mortar supply port 20 is applied to the upper surface of the molded body 5 and smoothed by the roller 21. The molded body 5 then proceeds to a concrete panel cutting device. There is a cutting device which moves on the rail 6 in synchronization with the traveling speed of the conveyor 2, and a holding device 8 therein moves on a rail 9 which is at a right angle to the rail 6 and changes according to the length of the pallet 1. And cut the concrete molding. The cut product is transported to a curing area (not shown) while being placed on the pallet 1, cured for a certain period, and shipped as a product.

2) FIG. 3 is an explanatory view showing the main structure of the molding section, and FIG. 4 is a sectional view taken along the line AA. 10 is an upper pressure frame,
Reference numeral 12 is a lateral pressure frame, which is vibrated under pressure by vibrating bodies 11 and 13, respectively. A molding frame is formed on the pallet 1 by the upper pressure frame 10 and the side pressure frame 12. Further, the rotary spiral core rod 14 is disposed in the above-mentioned molding form so as to penetrate the dam plate 17, and is rotated by an electric motor 16 connected to a flexible conductive drive shaft 15 to form a hollow hole in the concrete panel. 18 is formed. Rotating spiral core rod 14
Since the surface is formed in a spiral shape, the filling degree of the concrete material is improved by the effect of pressing and extruding.

In the next makeup mortar supply device 19, makeup mortar is supplied from the mortar supply port 20, applied onto the upper surface of the molded body, and smoothed by the roller 21. FIG. 5 shows a perspective view of the product separated from the pallet after curing.

INDUSTRIAL APPLICABILITY According to the present invention, a large amount of long concrete panels can be continuously molded on a line. Therefore, it is possible to produce a long concrete plate which is superior to the conventional method in terms of product treatment, quality control, labor-saving productivity, etc. As a result, compared to the conventional method, the amount of equipment is reduced, so that a large factory area is not required, and the solvent for cosmetic application is centralized and the curing can be concentrated in one place. Cost reduction can be achieved.

Further, the centralized management of the solvent can prevent the human body from being injured due to the scattering of the solvent, and since it is not necessary to use a crane, the risk of an industrial accident is reduced.
