Description

[Detailed description of the device]

TECHNICAL FIELD The present invention relates to a joint structure for roofing materials that are installed on a steep roof.

[Background technology]

Conventionally, a plurality of roof panels are laid in the direction of the eaves and purlins, and the roof is tiled to form a roof.However, for a steep roof, the roof panel itself must be installed. In addition to being difficult and dangerous, it was difficult to secure waterproofness and step crack strength at the joint between the roof tiles, resulting in poor workability.

[The purpose of the device]

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily roof the roofing material on a steep roof and to easily secure waterproofness to improve workability. , To further improve the strength of stepping cracks.

DISCLOSURE OF THE INVENTION The roof material joining structure of the present invention is a ridge of a front panel 2 of a roof panel A having a length substantially extending along the eaves direction formed by stretching a surface panel 2 on a frame 1. A side end located along the eaves direction is recessed downward to form a step 3, and a plurality of roof tiles 5 having a width substantially equal to the length of the roof panel A in the purlin direction are attached along the eaves direction. The roofing material R is formed, the roofing materials R are butt-joined to each other in the purlin direction, and a downwardly curved trough portion is formed in the middle of the trough member 4 arranged on the stepped portion 3, and both sides of the trough portion are formed. The contact part 8 with a flat upper surface is provided on both sides, and both contact parts 8,8
Connect the draining pieces 10 with the tip folded back to the side of each,
The overall width dimension of the gutter member 4 is substantially matched to the both step portions 3, 3 and the contact portion 8 is opposed to the back surface of the roof tile 5, and the above-mentioned object is achieved by this configuration. It is a thing. That is, in roofing construction, a plurality of roof materials R
Can be easily erected by installing them along the direction of the purlin 6 and the gutter member 4 is arranged on the step portion 3 of the surface plate 2 of the roof panel A. Since the waterproofness of the joint B can be ensured, and the contact portions 8 formed on both sides of the gutter member 4 are opposed to the back surface of the roof tile 5, the strength of the step crack at the joint B is improved. is there. Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings. The roof panel A is composed of a frame 1 and a surface plate 2 which is a plywood. In this embodiment, the frame body 1 is composed of a main body 1a assembled in a lattice shape and an auxiliary material 1b arranged along the longitudinal direction of the main body 1a, and the height of the main body 1a is lower than that of the auxiliary material 1b. In addition, by making the thickness of the auxiliary plate 2b stretched on the auxiliary member 1b smaller than the thickness of the surface plate body 2a stretched on the main body 1a, one side end portion along the longitudinal direction of the surface plate 2 is formed. A step portion 3 is formed. In addition, the step portions 3 may be provided at both end portions of the roof panel. The length of the roof panel A in the longitudinal direction is substantially the same as the length of the roof to be installed and installed in the eaves direction, and the widthwise direction thereof is substantially the same as the width of the roof tile 5. In this roof panel A, a plurality of roof tiles 5 such as slate plates are positioned such that one side in the purlin direction is located up to approximately the center of the stepped portion 3 and the other side is projected from the other end of the roof panel A. The roof material R is constructed by attaching the roof panel A along the direction of the eaves. When the roof panel A has the step portions 3 at both end portions as in this embodiment, the roof tiles 5 are attached so as to fit snugly in the width direction. In this embodiment, as the roof panel A, a plurality of roofing materials R having step portions 3 at both end portions are abutted at the step portions 3 along the direction of the purlin 6 as shown in FIG. Roof tile 5
They are joined to each other and are sequentially attached to the rafter 7. The gutter member 4 is arranged across both the step portions 3 so that rainwater entering from the gap 9 of the joint B between the roof tiles 5 can be drained to the eaves as shown in FIG. Further, both sides of the gutter member 4 are contact portions 8 and face the back surface of the roof tile 5 of the joint portion B. In addition, draining pieces from both sides of the gutter member 4
It has a series of 10, ensuring reliable waterproofness.

[Effect of device]

According to the present invention, the side edge of the roof panel, which is formed by stretching the surface plate on the frame and extends substantially over the entire length in the direction of the eaves, is located downward along the direction of the eaves. A step is formed by recessing the roof panel, and multiple roof tiles with a width approximately equal to the length of the roof panel in the purlin direction are attached along the eaves direction to form the roof material, and the roof materials are abutted in the purlin direction. Joined and formed a gutter part that is concavely bent downward in the middle of the gutter member arranged on the step part, and provide a hit part with a flat upper surface on both sides of the gutter part, and the side parts of both hit parts Since the draining pieces with the tips folded back are connected to each other, the overall width dimension of the gutter member is approximately matched to both step portions, and the contact portion is opposed to the back surface of the roof tile, so that roofing construction At this time, by installing multiple roofing materials along the purlin direction, tiles can be abutted against each other and easily roofed, Also, since the gutter member is arranged on the step part of the roof panel, the waterproof property of the tile joint can be secured by this gutter member, and the contact portions formed on both sides of this gutter member face the back surface of the tile. Since it is made possible, it is possible to improve the strength of step cracking at the joint portion, and it is possible to reliably support the vicinity of the edge of the roof tile with the flat upper surface of the contact portion,
Even in the back part of the step, rainwater that has passed over the hit part has the effect of being drained by a draining piece whose tip is folded back.
