Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to roofs such as terraces, carports, balconies, etc., which are used to prevent the roofing material from being lifted and fluttered by the blowing of wind from under the roof, and further from the frame. The present invention relates to a structure for preventing a roof material from coming off.

[0002]

2. Description of the Related Art Generally, an edge of a roofing material of a terrace roof includes a rafter hook (rear frame) fixed to an outer wall of a building frame, a front frame supported by a support at a position away from the outer wall, and a rafter hook. It is attached by fitting into a fitting groove formed inside a rectangular frame formed by the rafters and the side frames at both ends which are bridged with the front frame at regular intervals. The same applies to roof materials such as carports and balconies.

[0003]

By the way, when a strong wind blows toward the building frame, the wind hits the outer wall of the frame, and a part of the wind blows up along the wall, and the wind blows against roof materials such as terraces, carports and balconies. Spray from below. For this reason, the roofing material is lifted up and flexes and flutters. When the roofing material flexes, the central portion is lifted, so that the central portion of the roofing material is necessarily drawn to the center side. As a result, the edge of the roofing material may fall out of the fitting groove of the frame. The roofing material is relatively firmly fixed on the rafter because it is pressed from above by the rafter cover, but when the rafter pitch is large, the roofing material is likely to come off. The front and rear frames are only fitted in the fitting grooves, so if a slightly thin roofing material is fitted into the fitting groove of the roofing material, the roofing material is easily bent and comes off. Cheap. When the roofing material comes off, the roofing material loses its support and flies by the wind, which is dangerous, and the work of fitting the roofing material into the frame again is very troublesome.

If the fitting groove of the roofing material and the thickness of the roofing material are always appropriate and the pitch of the rafters is reduced, such accidents can be reduced. However, various types of roofing materials can be used in accordance with the thickness of the roofing material. It is also possible to correspond to the size of the size fitting groove finely,
Reducing the pitch of the rafters also has the problem of increasing costs.

[0005] The present invention solves the above-mentioned problems, and can effectively prevent escape even when a strong wind blows.
An object of the present invention is to provide a structure for preventing a roof material from coming off, which can reduce the cost.

[0006]

In order to solve the above-mentioned problems, a structure for preventing detachment of a roofing material according to the present invention is provided with a fitting for preventing detachment in a roofing material insertion groove formed in a front frame or a rear frame of a roof. The roof material is inserted and fixed between the upper edge of the insertion groove and the stopper metal fitting.

It is preferable that the stopper metal has elasticity and presses the roofing material against an upper edge of the roofing material insertion groove.

In the insertion groove, a front edge of an upper edge and a lower edge longer than the upper edge are formed in a substantially U-shape by a connecting edge, and a supporting edge shorter than the connecting edge is erected at an opening end of the lower edge. It is preferable that the roof material is formed between the upper edge and the support edge.

The detachment prevention metal fitting is formed by bending a holding piece smaller than the height of the connecting edge on one side of a pressing piece disposed along the upper edge, and on the other side of the pressing piece. It is preferable that a substantially V-shaped bent piece is formed, and the bent piece is attached so as to correspond to the opening side of the insertion groove.

Next, as shown in FIG. 5, the front frame 4 has a gutter portion 15 at the front of the hollow portion 14, an insertion groove 16 for the roofing material 7 above the hollow portion 14, and a hollow portion 14. The rear part is provided with a receiving part 18 at the end of the rafter 5 and the side frame 6,
Caps 17 are fixed to both ends.

The roofing material 7 is made of acrylic resin, polycarbonate or the like, and has front and rear ends formed inside the front frame 4 and the rear frame 3, respectively, as shown in FIGS. As shown in FIG.
As shown in (b), both left and right ends are rafters 5 or side frames 6.
And the cover member 12. As shown in FIGS. 3 and 4, the rear end and both sides of the roofing material 7 are attached via bead materials 19a and mohairs 19b.

By the way, as shown in FIGS. 5 and 6, a slip-off preventing bracket 20 is provided in a roof material 7 insertion groove 16 formed in the front frame 4, and the roof material 7 is located above the insertion groove 16. It is inserted and fixed between the edge and the stopper metal fitting 20. Therefore, the manner in which the front end of the roofing material 7 is attached to the front frame 4 will be described in detail.

The front frame 4 is formed with an insertion groove 16 for the roof material 7. The insertion groove 16 is formed in a substantially U-shape by connecting a front edge of an upper edge 21 and a lower edge 22 longer than the upper edge 21 with a connection edge 23. At the same time, a supporting edge 24 shorter than the connecting edge 23 is formed upright at the end of the lower edge 22 on the opening side. Support edge 2
A projection 25 is formed on the inside of the upper end of 4. The size of the open end formed between the upper edge 21 and the support edge 24 is sufficiently large.
