Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the structure of a connecting part at an inside corner when decorative boards are pasted horizontally in the form of a clapboard.

[Prior art]

Conventionally, in order to join vertically adjacent decorative boards 6 in the form of a clapboard, as shown in FIG.
1, the projecting length of the convex portion 10 is made longer than the depth of the recess 11, and a groove 7 as a joint is formed between the decorative boards 6 that are vertically adjacent to each other. When connecting the decorative boards 6, which are vertically joined in the form of paneling, at the inside corners, one of the decorative boards is placed so as to be orthogonal to each other through the inside corners, as shown in FIG. 6 and the side edge of the other decorative board 6 were butted together and fixed to the vertical base material 8.

[Problem that the invention attempts to solve]

In the above-mentioned conventional example, a gap A communicating between the inside and outside is created in the part where the grooves 7 as joints of the left and right adjacent decorative boards 6 meet through the inside corner, and the vertical base material 8 is visible through it, resulting in a poor appearance. In addition to this, there is also the problem that dust accumulates in the gap A, and grooves 7 as joints are formed between the vertically adjacent decorative boards 6 by fitting the protrusions 10 and the recesses 11. However, since there is no positioning device, it is difficult to set the width L of the groove 7 to a constant value, and there is a difference in the width L of the left and right grooves 7 that are adjacent to each other through the inside corner, which also deteriorates the appearance. In addition, there was a problem in that the side end surfaces of the decorative board 6 were exposed, which also resulted in a poor appearance.

[Means to solve problems]

In order to solve the above problems, a joiner 9 is used at the inside corner, and the first recess a of the joiner 9 is
The side ends of the decorative board 6 are fitted into the second recesses b, respectively, and the positioning protrusions 5 are provided which protrude from the first recess a and the second recess b at equal intervals in the vertical direction so as to be adjacent to each other in the vertical direction. It is designed to fit into the groove 7 as a joint between the decorative boards 6. By doing this, the side end of the decorative board 6 enters the first recess a to the second recess b, and the positioning protrusion 5 fits into the groove 7 serving as a joint, so that the gap created by the groove 7 as in the conventional case. This eliminates the problem of not being able to see the vertical base material and deteriorating the appearance, and also eliminates the problem of dust accumulation.
In addition, the width L of the grooves 7 of each part can be aligned to improve the appearance by positioning with the positioning protrusion 5.
By fitting the side ends of the decorative board 6 into the first recess a and the second recess b, the side end surfaces of the decorative board 6 are no longer exposed, and the appearance can be improved in this respect as well.

〔Example〕

In FIG. 4, reference numeral 9 denotes a jointer, which is made of aluminum, synthetic resin, a vinyl chloride-coated steel plate obtained by coating a steel plate with vinyl chloride resin, or a painted steel plate. The joiner 9 may be made of any other material. Joyner 9
is an L-shaped long cover piece 2 that is attached to the vertical base material 8 and bent at a substantially right angle to the front surface of the long mounting piece 1, and is integrated with the base end piece 3 of the long cover piece 2 so that it is substantially perpendicular to the mounting piece 1. The mounting piece 1 and cover piece 2
The attachment piece 1, the base end piece 3 of the cover piece 2, and the additive 8a attached to the vertical base material 8 are formed with a recessed part a.
Accordingly, the second recess b is formed to be perpendicular to the first recess a. On the inner surface 4a of the free end piece 4 extending from the proximal end piece 3 and on the side surface 3a of the proximal end piece 3 on the opposite side to the free end piece 4, a groove is provided at the same position over the entire length of the cover piece 2. A large number of positioning protrusions 5 having a pitch P and the same width W are formed. In other words, the first recess a
A large number of positioning protrusions 5 are formed in the second recess b at equal intervals in the vertical direction. Reference numeral 6 designates a decorative board, which, like the conventional one shown in FIG. 1 and as shown in FIG. 6, has a protrusion 10 at one end in the width direction and a recess 11 at the other end. , the protrusion length of the protrusion 10 is made larger than the depth of the recess 11, and the protrusion 10
The groove 7 as a joint is inserted into the recess 11.
It is designed so that it can be formed. As shown in FIG. 5, the mounting piece 1 is attached to the vertical base material 8 using nailing means (not shown), and then, as shown in FIG. Fit the side end of the L-shaped cover piece 2 into the first groove a between the inner surface of the mounting piece 1 and the convex part 10 and the concave part 11 of the decorative board 6 that are vertically adjacent on the right side. are fitted to form grooves 7 as joints, and are butt-joined in the form of a clapboard. Also, on the left side of the inside corner, fit the side end of the left side decorative board 6 into the second recess b between the outer surface of the base end piece 3, the mounting piece 1, and the additive 8a, and vertically fit it in the same way as above. The decorative boards 6 adjacent to each other in the direction are butted and joined to form a clapboard shape, forming grooves 7 as joints. In this state, the side ends of the left and right decorative boards 6 are fitted into the first recesses a to second recesses b and are covered with the cover pieces 2. Further, the width W of the positioning protrusion 5 of the joiner 9 is made approximately equal to the width L of the groove 7 as a joint of the decorative boards 6 which are butt-jointed. Decorative board 6 that has been joined
The positioning protrusions 5 are fitted into the grooves 7 serving as joints on the left and right sides of the inside corner, and the positions of the left and right grooves 7 as joints at the inside corner and their width L can be determined as specified. .

[Effect of the invention]

As described above, the present invention uses a joiner at the inside corner to attach the attachment piece of the joiner to the vertical base material, and the decorative part is arranged perpendicularly to the first recess and the second recess of the joiner, which are perpendicular to each other. The side ends of the boards were fitted into each other, and the positioning protrusions provided in the first recess and the second recess at equal intervals in the vertical direction were fitted into the grooves as joints between the vertically adjacent decorative boards. When the side edge of the decorative board enters the first recess or the second recess, the positioning protrusion fits into the groove serving as a joint, and the vertical base material is visible without the gap created by the groove as in the past. In addition to improving the appearance of the product, it also prevents dust from accumulating as in the conventional method.Moreover, the positioning protrusions fit into the grooves as joints for positioning, making it possible to align the width of the grooves in each part. This also improves the appearance.Furthermore, by fitting the side edges of the decorative board into the first and second recesses, the side edges of the decorative board are no longer exposed, which improves the appearance as well. It is something that can be done well.
