Description

[Detailed Description of the Invention] Industrial field of application The present invention is intended to cover a ridgeline near the end of a ridge, and also to wrap a ridge end portion inclined downward from the ridgeline of the ridge. It is related to the ridge end cover used in the dormitory.

2. Description of the Related Art Conventionally, in order to form this kind of ridge end cover with a sheet metal material, the left and right slopes having a substantially mountain-shaped cross section and the end faces inclined downward between the hypotenuses of the left and right slopes are formed. The triangular portion of a predetermined angle with the apex angle as the base point is cut away from one side of the end face, and the left and right slopes are formed into a substantially chevron cross section by joining the notched edges together, and the slope of each slope is It is usual to form an end face that slopes downward between the hypotenuses.

However, in the ridge-end cover of this ridge, one side of the end face is formed by bringing the notched edges together and joining them together, so rainwater enters as one side due to the notched edges erodes due to changes over time. It is easy to cause a situation.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the present invention, the left and right slopes having a substantially mountain-shaped cross section and the end faces formed between the hypotenuses of the left and right slopes and inclined downward are formed by bending from a single sheet metal material. The purpose is to provide an improved cover of the ridge.

Means for Solving the Problems In the ridge end cover of the dormitory according to the present invention, the sheet metal material is valley-folded along the center line of the sheet metal material, and an oblique angle of a predetermined angle is provided from the center line to the left and right. A mountain fold is made along a square line, and the left and right slopes of the cross-section substantially mountain shape whose diagonal line is the ridge and the end faces that are formed between the hypotenuses of the left and right slopes and that slope downward are made of a single plate. It is configured by bending a sheet metal material.

Action In the ridge end cover of this dormitory, both the ridgelines of the left and right slopes that are bent and formed in a substantially mountain-shaped cross section and the slopes of the end faces that are formed between the slopes of the left and right slopes are notched. Since it can be bent and formed from a single sheet metal material without forming a sheet metal member, it can be formed without the presence of a notch joint portion or the like of the sheet metal material in the portion enclosing at least the upper surface side of the purlin.

Embodiments The following will be described with reference to the accompanying drawings.

The ridge end cover shown in the figure is placed so that it is connected to the ridge cover that mainly encloses the ridgeline of the ridge, so that it covers the ridge edge that slopes downhill near the end of the ridge. To be done. The entire cover is formed of a sheet metal material such as stainless steel, and the sheet metal material is formed of a single plate. This sheet metal material is cut into a predetermined shape as shown in FIG.
A ridge end cover having a predetermined three-dimensional shape is formed by bending along a fold line indicated by a broken line and valley-folding along a fold line indicated by an alternate long and short dash line. The part indicated by the chain double-dashed line in the figure is the center line X that serves as a reference line when a single plate is shaped into a predetermined shape.

From the single plate, the left and right slopes 1, which have a substantially chevron cross section,
2 and an end face 3 that is formed between the hypotenuses of the slopes 1 and 2 and that slopes downwardly. In addition to this, the rising plate portions 4, 5, 6 on the three sides and the fixing plate portions 7, 8, 9 on the three sides projecting laterally are both shaped.

In this shaping, a portion which is a ridge line continuous from the apex 10 of the end face 3 is drawn along the angles θ ₁ and θ ₂ opened by desired angles from the center line X of the sheet metal material. The angles θ ₁ and θ ₂ may be about 4 ° when the apex angle θ ₃ of the end face 3 is set to 86 °, and the portions corresponding to the opening angles θ ₁ and θ ₂ are valley-folded at the center line X shown by the broken line. At the same time, the slanted lines 11 and 12 shown by the alternate long and short dash line are mountain-folded so that they are bent toward each other. In the off-bending, the ridge line Y of the ridge end cover can be formed as shown in FIG. 2, and the end face 3 is continuous with the oblique sides 13 and 14 of the left and right slopes 1 and 2, and the desired angle from the apex 10 to the roof slope can be obtained. It can be formed by inclining to a downward slope of a corner.

In the ridge end cover of this dormitory, the diagonal line 1 with the opening angles θ ₁ and θ ₂
The lower end sides 15 and 16 of the slopes 1 and 2 are drawn in parallel with the lower end sides 1 of the rising plate portions 4 and 5 continuous with the inclined faces 1 and 12.
The outer end sides 19 and 20 of the fixing plate parts 7 and 8 and the fixing plate parts 7 and 8 are drawn in parallel with the oblique lines 11 and 12. Further, the lower end side 21 of the end face 3 is drawn with the corner portion θ ₄ set to 47 °.
Lower edge 22 of rising plate 6 and outer edge 2 of fixed plate 9
3 is drawn in parallel with the lower end side 21. Each of these sides 15-
Along the lines 20, 21-23, the cuts 24, 25 are inserted in a predetermined direction, and the surplus portion is cut off to cut each side 15-20,
By bending 21 to 23, the rising portions 4, 5, 6
In addition, the fixed plate portions 7, 8 and 9 can be bent and formed. At that time, the bending margins 26 provided on the left and right of the fixed plate portion 9,
The corner portions can be joined by folding 27 from the outer end sides of the fixing plate portions 7 and 8. In addition, one side of the rising plate portion 6 and the end portions of the rising plate portions 4 and 5 are bent inward at the center broken line, and one side of the fixed plate portion 9 and each end portion of the fixed plate portions 7 and 8 are end faces. Angles θ ₅ , θ ₆ , θ ₇ , which are the same as the angle θ _{4 of} 3
By setting the angle to θ ₈ and overlapping them, it is possible to join the slopes 1 and 2 and the end face 3 as corners that are bent at the same angle as the hypotenuses 13 and 14. Standing plate part 4,
5 and 6 are preferably formed by projecting the upper end side forward and forming the lower end side into a beveled surface with a slight angle at the back, which is the angle θ
It can be formed by setting ₉ and θ ₁₀ to 68 °.

The ridge end cover of the ridge constructed in this way is provided with the fixing plate portion 7,
By attaching 8 and 9 to each slope of the dormitory and nailing it, it is possible to install and wrap the edge of the ridge of the ridge. At that time, even if the angle varies depending on the house, the bending of the hypotenuses 28 and 29 formed at the corners of the fixing plate parts 7, 8 and 9 as shown in Figs. 3a and 3b. It can be handled by changing the corner. In addition, the bending angles of the oblique sides 13 and 14 that connect the slopes 1 and 2 and the end surface 3 are changed according to the adjustment of the bending angle, and this is achieved by changing the inclination angles of the rising plate parts 4, 5, and 6. be able to.

Effects of the Invention As described above, by approaching the ridge end cover of the dormitory according to the present invention,
Since it can be formed by bending each surface from a sheet metal material of one sheet without making a cut on at least the ridgeline of the left and right slopes and the hypotenuse that bends the left and right slopes and the end surface, it can be used for a long time However, there is no possibility that rainwater will enter the purlin side.
