Abstract

PROBLEM TO BE SOLVED: To reduce the number of paintings to decrease manufacturing processes and to provide a manufacturing method of flooring capable of promoting productivity. SOLUTION: Vertical grooves 2 are so bored in an approximately rectangular floor master board 1 that they are parallel with the longitudinal direction of the floor master board 1 and, at the same time, tongues 3 are made to the end edges parallel with the longitudinal direction of the floor master board 1. Horizontal grooves are so bored in the surface of the floor master board 1 that they are parallel with the short direction of the floor master board 1 and, at the same time, the tongues are made to the end edges parallel with the short direction of the floor master board 1. Recessed grooves for forming the surfaces on the front sides of the tongues are formed in the cener position of the longitudinal direction of the floor master board 1. Then, a colored painting is applied to the front side of the floor master board 1. Successively, the floor master board 1 is cut off along the recessed grooves and, at the same time, the surfaces of the recessed grooves are so tongued that they are used for the surfaces on the front sides of the tongues. Then, the floor master board 1 is cut off along the vertical grooves 2 to form small divided piece plates. The small divided piece plates are assembled to connect the longitudinal end edges of the small divided piece plates to each other.

The small piece plate 7 is formed by cutting along. As shown in FIG. 11, the small piece pieces 7 are assembled and arranged in a stepwise manner, and the edges parallel to the longitudinal direction of the small piece pieces 7 are joined to form the floor material 8.

[0003]

However, in the above conventional example, as shown in FIG. 7, a colored coating is applied to the surface of the original floor plate 1 with the vertical grooves 2, the horizontal grooves 4 and the real portions 3 formed in the original floor plate 1. After processing the real part 6 as shown in FIG.
Has to be partially colored on the surface side, which requires two coatings, resulting in a large number of manufacturing steps and low productivity.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and an object of the present invention is to provide a method of manufacturing a flooring material capable of improving productivity by reducing the number of coating steps and the number of manufacturing steps.

[0005]

In order to solve the above-mentioned problems, a method of manufacturing a flooring material according to the present invention is characterized in that a vertical groove is formed on a surface of a substantially rectangular flooring plate 1 so as to be parallel to the longitudinal direction of the flooring plate 1. 2 and a real part 3 at the edge parallel to the longitudinal direction of the floor plate 1.
And a lateral groove 4 is formed on the surface of the original floor 1 so as to be parallel to the transverse direction of the original floor 1, and the actual part 6 is actually machined on an edge parallel to the transverse direction of the original floor 1. And a floor plate 1
A concave groove 9 for forming a surface on the front side of the real part 6 is formed at an intermediate position in the longitudinal direction of the base plate 1. The original plate 1 is cut and the actual processing is performed so that the surface of the concave groove 9 becomes the surface side of the real part 6, and then the floor original plate 1 is cut along the vertical groove 2 to form the small piece piece 7. And this small piece board 7
And joining the longitudinal edges of the small piece pieces 7 to each other. That is, a concave portion for actually processing the real portion 6 at an edge parallel to the transverse direction of the floor original plate 1 and for forming a surface of the real portion 6 on the surface side at an intermediate position in the longitudinal direction of the floor original plate 1. In order to apply a colored coating to the surface of the floor plate 1 after the formation of the base 9, the surface side of the real part 6 is also applied with a coating. There is no unpainted part on the side and the flooring 8 without unpainted part on the front side is formed. As a result, only one coloring coating step is required, and the number of coating steps is reduced, thereby reducing the number of manufacturing steps and improving productivity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor plate 1 is formed in a substantially rectangular shape. The original floor plate 1 is formed by, for example, integrally providing a surface decorative board to a base material of plywood. First, a plurality of vertical grooves 2 are formed at substantially equal intervals on the surface of the floor original 1 so as to be parallel to the longitudinal direction of the floor original 1, and a real part 3 is formed on an edge parallel to the longitudinal direction of the floor original 1. Is formed. As the real part 3, a female nut 3a is provided at one edge and a male nut 3b is provided at the other edge. Next, as shown in FIG.
A horizontal groove 4 is formed so as to be parallel to the lateral direction of the base plate 1, and a concave groove 9 for forming a surface on the front side of the real part 6 in the surface of the floor base plate 1 at a middle portion in the longitudinal direction of the floor base plate 1. Are formed, and a real part 6 is formed at an edge parallel to the lateral direction of the floor plate 1. The real part 6 has a female nut 6a at one end and a male nut 6b at the other end. Then, as shown in FIG. 2, the surface of the original floor plate 1 is colored with the vertical groove 2, the horizontal groove 4, the real part 3, the real part 6, and the concave groove 9 formed. After the colored coating is applied as described above, the floor original plate 1 is cut along the groove 9 to form the divided original plate 5, and the surface of the groove 9 on the portion cut along the groove 9 is the surface on the front side. Is formed. As the actual portion 6, a female member 6a is provided on one of the divided original plates 5, and a male member 6b is provided on the other divided original plate 5. Next, the divided original plate 5 is cut along the longitudinal grooves 2 as shown in FIG. The small piece pieces 7 are assembled as shown in FIG. 5, a plurality of small piece pieces 7 are arranged in a step-like manner, and the edges parallel to the longitudinal direction of the small piece pieces 7 are abutted and joined. Thus, the floor material 8 is formed. At this time, for example, the notch 10 provided on the back surface side of the edge parallel to the longitudinal direction of the small piece pieces 7 is filled with an elastic synthetic resin and joined so as to be bendable. A cushioning material such as rubber is attached to the back surface of the flooring material 8 as necessary. The floor material 8 is formed as described above, but even if the color coating is applied only once as described above, the appearance is good without an unpainted portion being formed on the surface side.

[0007]

According to the present invention, a vertical groove is formed on the surface of a substantially rectangular floor plate so as to be parallel to the longitudinal direction of the floor plate, and a real part is formed on an edge parallel to the longitudinal direction of the floor plate. In the surface of the floor plate, a horizontal groove is formed so as to be parallel to the width direction of the floor plate, and at the edge parallel to the width direction of the floor plate, the real part is actually processed. A concave groove for forming the front surface of the real part is formed at an intermediate position of the direction, then a colored coating is applied to the front side of the floor original, and then the floor original is cut along the concave groove and the concave is formed. The actual processing is performed so that the surface of the groove is the surface on the front side of the real part, and then the floor base plate is cut along the vertical groove to form a small piece plate, and the small piece plate is assembled and small. Since the longitudinal edges of the split piece plate are joined together, the surface side of the real part can be painted even with a single colored coating. It can be in a state, there is no unpainted part on the surface side even if it is not partially colored later, as in the past, a floor material without unpainted part on the surface side is formed, Only one color coating step is required, and the number of coating steps can be reduced to reduce the number of manufacturing steps and improve productivity.
