Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular tubular structure, and more particularly to a gate pillar and a gate sleeve.

[0002]

2. Description of the Related Art Conventionally, when manufacturing a rectangular tubular structure (1) such as a gate pillar or a gate sleeve, as shown in FIGS. Width board (30A, 30A)
And two side plates (30B, 30B) are cut off, and each width plate (30A) and side plate (30B) are obliquely cut at about 45 ° at the joint edge, and the diagonally cut width plate (30A) and side plate (30A) The rectangular tubular structure (1) was manufactured by butt-fixing the cut surfaces with each other and adhering and fixing them.

[0003]

However, as shown in FIG.
As shown in (a) or FIG. 12 (a), when there is a portion where the cutting line L overlaps the vertical joint (8), the width board (30A) and the side plate are
At the corners of the rectangular tubular structure (1) where (30B) and the cut surfaces are butted and fixed to each other, the edges of the vertical joints (8) and the bricks (10) on both sides project. There is a problem that the corners of (1) are W-shaped and easily chipped.
In addition, since the thickness of the cutting blade (3 to 4 mm), the continuity of the handle of the rectangular tubular structure (1) is lost, and if the bonding is performed as it is, the corners of the rectangular tubular structure (1) will look unnatural, There was also the problem of poor design. Furthermore, unlike the joint between the same-rise corner column and the outer wall of a general house, the joint between the width plate (30A) and the side plate (30B) of the rectangular tubular structure (1) is sealed by vertical joints. Since the horizontal joints are directly in contact with each other without the provision of the horizontal joints, there is a problem that the lateral joints are very noticeable even when the lateral joints are slightly displaced. Further, when the depth of the vertical joint (8) is 3 mm or more, the protruding amount of the end edge of the brick portion (10) increases, so that FIG.
When the position of the cutting line L is set within 5 mm from the vertical joint (8) as shown in, there is a problem that the corner portion of the square tubular structure (1) is more easily chipped, and the square tubular shape In order to prevent the corners of the structure (1) from being chipped, there is also the problem that the chamfered corners must be wide as shown in FIG. 13 (e). Furthermore, if the position of the cutting line L is arbitrary, the left and right balance of the pattern on each surface is lost, and the appearance of the rectangular tubular structure (1) is impaired.

[0004]

Means for Solving the Problems The present invention is, as a means for solving the above-mentioned problems, a plurality of brick portions (10) surrounded by vertical joints (8) and horizontal joints (9) on the surface. The horizontal joints (9) are vertically and horizontally arranged, and each horizontal joint (9) is cut vertically into a plate (30) having a pattern that penetrates the entire length of the plate (30), and two width boards (30A, 30A) and two Cut off the side plates (30B, 30B),
In the rectangular tubular structure (1) in which the two width plates (30A, 30A) and the two side plates (30B, 30B) are fixed together, the cutting line between the width plate (30A) and the side plates (30B) is fixed. L provides the rectangular tubular structure (1) set in a position not overlapping the vertical joint (8). When the depth of the vertical joint (8) is 3 mm or more, the cutting line L is preferably separated from the vertical joint (8) by at least 5 mm. Furthermore, in the width plate (30A) and the side plate (30B), the lengths from the left and right edges to the positions of the vertical joints (8) located at the left and right ends in each row of the pattern are substantially equal. It is desirable that the cutting line L be set to. Furthermore, the plate material (30) is preferably a ceramic outer wall material, and the rectangular tubular structure (1) is preferably a gate pillar or gate sleeve.

[0005]

[Function] The plate material (30) is vertically cut to obtain two width boards (30A, 30A).
When cutting A) and the two side plates (30B, 30B), the cutting line L between the width plate (30A) and the side plate (30B) is set so as not to overlap the vertical joint (8). The edge of the brick part (10) at the corner of the rectangular tubular structure (1) is less likely to be chipped. Further, in this case, if the cutting line L is separated from the vertical joint (8) by 5 mm or more, even if the depth of the vertical joint (8) is 3 mm or more, the brick of the corner portion of the rectangular tubular structure (1) is bricked. Part (10) edge is less likely to be chipped.
In each row of the pattern, the lengths from the left and right edges to the positions of the vertical joints (8) located at the left and right edges are substantially equal (l _L =
l _R ) If set, the left and right sides are balanced on each side of the rectangular tubular structure (1). The above l _L (=
l _R ) is preferably 5 mm or more, and further 30 to
40 mm is desirable.
