Description

[Detailed description of the invention] The present invention integrally extends the seams 2 having a horizontally U-shaped cross section on the back side of both side edges of the metal roofing board 1, so that the seams 2 between the left and right adjacent roofing boards 1 are A sacrificial plate 3 is placed under the gap 2 with the parts 2 facing each other, and the left and right edges 4 a , 4 of the upper part of the vertical protrusion 4 having a T-shaped cross section protrude from the center of the sacrificial plate 3 . b into the gap 2, and fit the fitting part 5, which is obtained by folding both sides of the disposable plate 3 toward the surface side, onto the outer surface of the gap 2, and then tighten the tip of the fitting part 5 to T.
This relates to a metal roof plate connecting device that is positioned above the upper part of the vertical protrusion 4 in the shape of a letter.

When connecting conventional metal roof panels, as shown in FIG.
is provided, and a sacrificial plate 3' is placed under the adjacent locking portions 6,
The left and right edges 4 a' and 4 b' of the vertical protrusion 4' having a T-shaped cross section protruding from the top of the sacrificial plate 3' are overlapped on the surface of the locking part 6, and the cross section is fitted from above the locking part 6. A locked piece 7a at the bottom of the inverted U-shaped cover 7 was locked to a locking portion 6.

However, in such a conventional example, the locking portion 6 of the roof plate 1'
Since it is only folded back to the front side for appearance, it is weak in strength and there is a risk that the locking part 6 may be deformed during transportation.It also requires a waste plate 3' and a cover 7, making the construction extremely complicated. There was a drawback.

Also, for those that last using conventional waste boards, it is the first
As shown in the figure, there was a problem in that the upper part of the sacrificial board protruded above the roof board, making it unsightly.

The present invention was developed in view of the above points, and its purpose is to ensure that the edges of the roof shingles are strong and resistant to deformation.
<An object of the present invention is to provide a metal roof plate connecting device that is easy to construct, is resistant to water leakage, and is resistant to blow-up.

The present invention will be explained in detail below with reference to Examples.

Reference numeral 1 denotes a metal roof plate, and on the back side of both side edges, flaps 2 having a horizontally U-shaped cross section extend.

A hook part 9 having a horizontally U-shaped cross section is provided at the upper edge of the roof board 1, and a hook part 8 is provided at the lower end edge of the roof board 1 by folding it back toward the back side.

A vertical protrusion 4 having a T-shaped cross section is provided in the center of the rectangular waste board 3 in the longitudinal direction, and fitted parts 5 are provided on both side edges of the waste board 3 by folding it back toward the back side. .

When constructing the roof shingles 1, the seams 2 of the left and right adjacent roof shingles 1 are butted against each other, and the sacrificial board 3 is placed under the seams 2, and the left and right edges of the vertical protrusion 4 are 4a and 4b are inserted into the gap 2, and the fitting portion 5 of the waste plate 3 is fitted onto the outer surface of the gap 2.

The connection in the vertical direction is performed by hooking the hooked portion 8 of the upper roof panel 1 to the hook portion 9 of the lower roof panel 1.

As described above, the present invention has a U-shaped flap with a horizontal cross section extending on the back side of both edges of the roof sheet, so it is more rigid than the conventional method of simply folding it back, and does not deform during transportation. It is safe and has a T-shaped cross section that protrudes from the center of the roof board, with the edges of adjacent left and right roof panels facing each other, and a waste board placed under the break. The left and right edges of the upper piece of the joint protrusion are inserted into the seam, and the fitted parts, which are folded back on both sides of the waste board, are fitted onto the outer surface of the seam, so that it does not touch the roof board in the lateral direction. Even if an external force is applied to cause the roof to shift, it will be blocked by the fitted part and will be prevented from coming off, and even if the butt between the roof sheets is insufficient, there will be no gap and there is a risk of water leakage. Moreover, since the tip of the fitted part is located above the upper part of the T-shaped joint projection, rainwater flows onto the upper part of the joint projection at the joint of the roof board, and Even if this rainwater flows into the root soil through the gap, it will not go over the tip of the fitted part and infiltrate, and furthermore, even though it is connected through the sacrificial board, the sacrificial board is connected to the roofing board. It does not protrude upward and is not unsightly, and the connection part is resistant to blow-up.
It is also easy to install, as it can be connected with just a scrap board.
