Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a construction board having a concavo-convex pattern used as an interior and exterior material for a house. Then, the insertion protrusion 3 is made to protrude outward from one side plate part 2, and a concave bent piece 4 that is concavely curved inward is formed on the other side plate part 2, so that the insertion protrusion 3 is formed on the outer surface of the concave bent piece 4. A construction board 6 is formed by providing an insertion recess 5 into which a concave curved piece 4 is provided to form a construction board 6, and a side board section provided with a concave curved piece 4 in imparting an uneven pattern 7 to the front panel 1 of this construction board 6. 2 is bent outward at an angle of 90° or more with respect to the back surface of the front panel section 1, and an uneven pattern 7 is given to the front panel section 1, and then this side panel section 2 is bent outward at an angle of 90 degrees or more with respect to the back surface of the front panel section 1. The present invention relates to a method for producing a construction board having a concavo-convex pattern, which is characterized by being bent inward at an angle of approximately 90°.

A construction board 6 as shown in FIG. 2 has side plate parts 2, 2 extending backward from both ends of a front plate part 1, and an insertion protrusion 3 and a concave bent piece 4 provided on the side plate parts 2, 2, respectively. In order to give the uneven pattern 7 to the front panel part 1 of
As shown in the figure, the uneven pattern 7 was formed by pressing the front and back sides of the front plate part 1 with uneven pattern forming tools 8, 8 such as an embossing press or an embossing roll. However, in such a conventional method, as shown in FIG. 7 could not be expressed.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a method for manufacturing a construction board having an uneven pattern, which allows the uneven pattern to be applied to the front surface of the front panel part. be.

The present invention will be explained in detail below with reference to Examples. The architectural board material 6 is formed into a long length by extrusion molding of hard vinyl chloride resin, ABS resin, styrene resin, etc., or by inserting a steel plate or aluminum plate as a core material into this. A cross section in which the side plate parts 2, 2 are respectively extended to the back, the insertion protrusion piece 3 is made to protrude outward from one side plate part 2, and the concave curved piece 4 is made to be concavely bent inward from the other side plate part 2. It is formed into a shape. The side plate portion 2 on which the concave curved piece 4 is provided as shown in FIG. 3a when extrusion molding the architectural board material 6
is opened at an angle α of 90° or more with respect to the back surface of the front plate part 1. In this case, the line connecting the inner end of the concave curved piece 4 and the base end of the side plate part 2 is at the front plate part 1. It is best to make an angle of 90° or more to the back of the In imparting the uneven pattern 7 to the front plate portion 1 of the architectural board 6 formed in this way, the third
As shown in FIG.
The front and back surfaces of the front plate part 1 are heated and pressed to give the front plate part 1 an uneven pattern 7. In this case, since the side plate portion 2 on which the concave curved piece 4 is provided is in a state of being bent outward, even if the concave and convex pattern forming tool 8 having the same length as the width of the front plate portion 1 is used, the concave curved piece 4 The pattern 7 does not become a hindrance in any way, and the uneven pattern 7 can be provided over the entire surface of the front plate portion 1. After forming the uneven pattern 7 in this way, with the front plate part 1 being held between the holding dies 9 and 9, the side plate part 2 having the concave curved piece 4 is pressed from the outside with the correction die 10. , the side plate part 2 is corrected so that the side plate part 2 is perpendicular to the front plate part 1. A roll may be used as the modified mold 10.
The back side of the architectural board 6 obtained as described above is filled with a foam 11 such as polyurethane foam. That is, as shown in FIG. 5, foamed material is injected into the back side of the construction board material 6 using a foaming injection machine 19, and then the foamed material is injected into the back side of the construction board material 6 using a foaming injection machine 19, and then this is poured into a double molded material consisting of an upper type caterpillar conveyor 12 and a lower type caterpillar conveyor 13. By sending the foamed material into the conveyor 14 and foaming and hardening it in the double conveyor 14, the foamed material 11 is filled into the back side of the construction board 6 as shown in FIG. Since the architectural board 6 is made of synthetic resin and the back side is filled with foam 11, it has excellent water resistance and heat insulation properties, making it ideal as an interior material for bathrooms, washrooms, toilets, etc. be.

Thus, the construction board obtained as described above has a nail 1 attached to it from the nailing piece 15 extending from the concave bent piece 4.
6, it can be attached to a wall base material, etc., and the connection between architectural boards is made by inserting the insertion protrusion 3 into the insertion recess 5 formed in the concave curved piece 4, as shown in Fig. 6. This can be done easily by doing this. When the construction boards are connected in this way, the nails 16 are hidden by the adjacent construction boards and are not exposed to the outside, and the adjacent construction boards are brought into close contact with each other, improving airtightness.

7 and 8 show another embodiment of the present invention, in which a front plate part 1 made of a hard material such as hard vinyl chloride resin and a side plate part 2 provided with a concave curved piece 4 are shown.
The architectural board material 6 is formed by co-extruding a hard material and a soft material so that a soft portion 17 made of soft vinyl chloride resin or the like is provided between the material and the material over the entire length. In this case, as shown in FIG. 7, the uneven pattern 7 can be applied to the entire surface of the front plate part 1 while the side plate part 2 provided with the concave curved piece 4 is bent outward at the soft part 17. In addition, if the flexible part 17 has a packing protrusion 18 protruding outward, the packing protrusion 18 will come into elastic contact with the adjacent building board when connecting the building boards, further improving airtightness. It is something that can be done. Incidentally, as shown in FIG. 9, the entire side plate portion 2 including the concave curved piece 4 may be formed of the soft part 17. In this case, since the concave curved piece 4 also has elasticity, the insertion protrusion 3 can be inserted into the insertion recess. 5 can be elastically fitted,
It is possible to further improve the airtightness, and furthermore, when driving the nail 16 into the nailing piece 15, the nail 1
It is also possible to ensure waterproofing between the nailing piece 6 and the nailing piece 15.

As described above, the present invention, when imparting a concavo-convex pattern to the front panel of a construction board, involves setting the side panel provided with the concave curved piece at an angle of 90° or more with respect to the back surface of the front panel. Since the uneven pattern is applied to the front plate while it is bent toward the front, the uneven pattern can be applied to the front using an uneven pattern forming tool with the same length as the width of the front plate without the fear that the concave curved piece will get in the way. Can be applied to the face plate,
It is possible to form an uneven pattern over the entire surface of the front plate portion.
