Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technique for preventing flat tiles such as asbestos-cement tiles from warping after construction.

[Background technology]

Flat tiles such as asbestos-cement tiles have been widely used for a long time, but flat tiles such as asbestos-cement tiles warp after installation, causing uneven horizontal seams and poor appearance after roofing. There was also the problem that the wind resistance strength was also reduced. The above-mentioned problem becomes especially noticeable when flat tiles are made into large plates.

[Purpose of invention]

The present invention was devised in view of the above points, and its purpose is to prevent flat tiles such as asbestos-cement tiles from warping, prevent uneven joints, and increase wind resistance. To provide a flat tile roofing structure that does not cause a decrease in the temperature, causes no problem even when using a large flat tile, and has a good appearance because a member for preventing the flat tile from warping is less noticeable.

[Disclosure of the invention] The roofing structure of the flat tile of the present invention is such that horizontally adjacent flat tiles 1 are butted together with a seam vertical board 2 interposed therebetween, and pressing pieces are placed on both sides from the front end of the upper edge of the seam vertical board 2. 3 is extended and the presser piece 3 is positioned on the upper surface of the front end of the flat tile 1, and the rear part of the seam vertical plate 2 is held down by the upper flat tile 1', with such a configuration. As a result, the holding piece 3 prevents the flat tile 1 from warping from the abutting portion at the front, achieving the above-mentioned object of the present invention.

The present invention will be explained in detail below with reference to Examples. In the figure, reference numeral 4 denotes a warp-preventing metal fitting used in the present invention, and a warp-preventing metal fitting 4 is formed by extending a presser piece 3 toward both sides at the front end of the upper edge of the longitudinally elongated seam vertical plate 2. . Further, the front and rear length of the seam vertical plate 2 of the warp prevention fitting 4 is equal to the front and back length of the flat tile 1, and the front and rear positioning pieces 5 are provided at the front and rear ends of the seam vertical plate 2 toward both sides.
A rear positioning piece 6 is provided. Also, Figures 2 and 3
In the case of the warpage prevention metal fitting 4 shown in the figure, the seam vertical plate 2
A lower horizontal piece 7 is provided protruding from both sides along the entire length of the lower edge. However, horizontally adjacent flat tiles 1 such as asbestos-cement tiles are butted together with a seam vertical board 2 interposed therebetween.
Place the presser piece 3 of the vertical seam plate 2 on the front upper surface of the horizontal butting part of the flat tile 1, and in this state, cover the upper flat tile 1' and make the seam vertically with the upper flat tile 1'. This is to hold down the rear part of the board 2, and since the joint vertical board 2 is held down by the upper flat tile 1', even if the lower flat tile 1 tries to warp from the front end of the horizontal butting part, it will not hold down. This will prevent it from being pressed by the piece 3 and warping. Further, by providing the front positioning piece 5 and the rear positioning piece 6 on the warp prevention metal fitting 4, the horizontally adjacent flat tiles 1 can be brought together without shifting in the front-rear direction. By the way, the warp prevention metal fitting 4 does not need to be fixed by nailing or the like.

[Effect of idea]

As described above, the present invention is to connect horizontally adjacent flat tiles with a seam vertical plate interposed therebetween, and to extend the presser pieces from the front end of the upper edge of the seam vertical plate to both sides, so that the presser pieces can be attached to the flat tiles. It is positioned on the upper surface of the front end and the rear part of the seam vertical plate is held down by the upper flat plate tile, which prevents flat tiles such as asbestos cement tiles from warping at the front of the butting part, and prevents horizontal butting. It is able to prevent unevenness in parts, is resistant to blowing up by the wind, and does not cause any problems even when using large flat plate tiles. Since it extends from both sides and is located on the top surface of the front end of the flat tile, the holding piece, which is a member to prevent the flat tile from warping, is present only on the top surface of the front end of the flat tile and is conspicuous. In addition, when attaching the flat tile by holding it down with a presser piece, it is not only necessary to insert the flat tile from the side, but also to insert the flat tile diagonally so that the bottom side is facing down. The front end of the flat tile can be inserted under the retaining piece even in the closed state, and various construction methods are possible.

[Brief explanation of the drawing]

Figure 1 is a plan view of the roofing state of the present invention, Figure 2 is a perspective view of the same flat tile with warp prevention metal fittings fitted into the side edges, and Figures 3a and b are warpages used in the present invention. FIGS. 4a and 4b are perspective views and plan views of another embodiment of the warp preventing metal fitting, in which 1 is a flat tile and 2 is a seamed vertical plate. , 3 is a holding piece, and 1' is an upper flat tile.
