DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner ridge plate used for a corner ridge (also referred to as a descending ridge) of a ridge type roof.

[0002]

2. Description of the Related Art As a corner ridge plate used in a conventional ridge type roof ridge, a long metal strip is simply creased along a longitudinal direction, and a cross section in a width direction has a substantially mountain shape. There was a through ridge type and a ridge type in which the lower end of the upper ridge was superimposed on the upper end of the lower ridge at the construction site using many ridges and placed on the corner ridge. .

[0003] The through-ridge type has a drawback that the upper surface thereof is flat, so that the appearance after installation is difficult to match with the step formed by the roofing material such as a flat tile. Although it is in harmony with the step formed by the step, it is necessary to engage many ridges and bolts at the construction site, the disadvantage of poor construction efficiency and insufficient securing of positional accuracy when engaged There was a disadvantage.

Therefore, as a through-ridge type corner ridge plate having an image of the insertion ridge, a plurality of V-shaped corner ridges are provided at predetermined intervals so that the descending side of the corner ridge is lowered as shown in FIG. A long corner ridge plate (1) having a step portion (2) in the longitudinal direction of the upper surface has been proposed. (2-13
No. 7418)

[0005]

However, the above-described prior art corner ridge plate of a through ridge type having a V-shaped stepped portion in the longitudinal direction of the upper surface as shown in FIG. 4 is a long corner. Since it is a ridge plate, it is often cut to adjust the length in order to fit it in the length of the corner ridge, and this cutting has a problem that a large amount of scrap material is lost.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem of a through-ridge type corner ridge plate having a V-shaped stepped portion in the longitudinal direction of the upper surface, and has an image of an insertion ridge. It is an object of the present invention to provide a corner ridge plate having a high work efficiency and a small loss of offcuts due to cutting.

[0007]

According to a first aspect of the present invention, there is provided a connecting corner ridge plate having a substantially mountain-shaped cross section in the width direction, and a plurality of connecting corner ridge plates provided at predetermined intervals so that the descending side of the corner ridge becomes lower. A corner ridge plate (1) having a V-shaped stepped portion (2) in the longitudinal direction of the upper surface, having a V-shaped lower end (3), and having an upper end (4) above. A plurality of wings each having a locking piece (5) bent inward and having a locked piece (6) bent downward inward at a lower end (3). An object (7) forms a corner ridge plate (1), and a locked piece (6) of a ridge part (7) located on the ascending side of the corner ridge and another located on a descending side of the corner ridge. A corner ridge plate (1) to which a locking piece (5) of a ridge part (7) is engaged and an engaging part (8) formed by this engagement is fixed. Object (7)
Bend downward and outward on both side edges of
A side end (9) with a substantially L-shaped cross section
And the side ends (9) of each wing (7) are fitted together.
It is characterized by having been done.

[0008]

[0009]

[Function] By overlapping and fixing the ridgework so that the lower end of the ridgework and the lower end of the roofing material such as a flat tile are aligned, a step portion continuous with the step formed by the roofing material is a corner ridge. Since it is formed on a board, the corner ridge board will have the appearance of the image of the insertion ridge. In addition, stacking and fixing a plurality of ridgeworks in advance before construction on the site reduces the number of members compared to the case where independent ridgeworks are constructed on site, and also reduces the number of members on the roof. Since less joint work is required, construction efficiency on site is improved. In addition, compared to a corner ridge plate in which a V-shaped step portion is formed by sheet metal molding or the like on a long metal band plate or the like, the corner ridge plate of the present invention in which a plurality of ridges are overlapped and fixed is provided. By increasing or decreasing the number of pieces to be connected, it is possible to reduce the generation of scrap material loss due to on-site cutting.

In addition, both sides are bent downward and outward, and
In a corner ridge plate using a ridge part having a substantially L-shaped side end partly protruding on the rising side of the corner ridge ,
By fitting the side edge of the other ridgework connected to the ascending side of the corner ridge to the side edge of the character shape, so-called lateral deflection in the width direction is prevented, so it is easy to secure positional accuracy , And the area to be superimposed is increased by the area of the protruding L-shaped side end portion, so that good rain can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 relates to one embodiment, in which (a) is a plan view,
(B) is a sectional view showing a section in the width direction. As shown in FIG. 1, the corner ridge plate (1) has a substantially mountain-shaped cross section in the width direction, and a plurality of V-shaped step portions (2) provided at predetermined intervals so that the descending side of the corner ridge is lower. , 2, 2) in the longitudinal direction of the upper surface. Further, the corner ridge plate (1) is formed by a plurality of ridge members (7, 7,...) Having a V-shaped lower end portion (3).

FIGS. 2A and 2B are sectional views showing a ridgework (7) used in the embodiment shown in FIG. 1, wherein FIG. 2A is a plan view and FIG. As shown in FIG.
Has a locking piece (5) formed at the upper end (4) by being bent upward and inward, and a locked piece () formed by bending at the lower end (3) downward and inward. 6). Then, the corner ridge plate (1) shown in FIG. 1 is configured by connecting four ridgework objects (7) shown in FIG.
