Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention involves engaging the ridge side and eave side engaging portions of double-sided boards adjacent in the direction of the eave ridge, so that the face plate is laterally roofed, and natural slate is placed horizontally in one row on the face plate. , relates to a roof surface structure in which plate-shaped roofing materials such as tiles are supported and fixed.

0002

2. Description of the Related Art Recently, roofs using plate-shaped roofing materials such as natural slate or tiles instead of roof tiles have been used for reasons such as their good appearance.

[0003] Conventionally, as a roof using the above-mentioned roofing material, waste boards are provided on the back-up material, opposite ends of laterally adjacent roofing materials are arranged on these waste boards, and are embedded in the back-up material. Roofing materials are fixed to the reinforcing bars with copper wires, and a large number of roofing materials are roofed in a staggered pattern. These panels are fixed to base materials such as rafters, and the roofing materials are placed as stones in the spaces between the panels. There was one that was fixed by pasting it on top of the backup material with adhesive.

0004

[Problems to be Solved by the Invention] In the above-mentioned conventional roof using plate-shaped roofing materials such as natural slate and tiles,
Since the opposing ends of horizontally adjacent roofing materials are brought into contact without overlapping one above the other, rainwater, etc. can easily enter the indoor side of the roofing material from the abutting or adjacent parts, causing water leakage.
In order to prevent water leakage, even if a complicated structure is used, such as providing a sacrificial board under each opposite end of the roofing material, it is difficult to reliably prevent water leakage.

[0005] In addition, panels in which a large number of roofing materials are fixed on backup materials are heavy and occupy a large area, so there is the problem that work at heights on the roof is difficult and dangerous. there were.

The present invention solves the above-mentioned problems, has a simple structure, can reliably prevent water leakage, and can be used to install plate-shaped roofing materials such as natural slate and tiles without requiring heavy labor or causing danger. It is an object of the present invention to provide a roof surface structure that can be roofed with less work.

[0007]

[Means for Solving the Problems] The present invention engages the ridge side and eave side engaging portions of double-sided boards adjacent in the direction of the eave ridge, so that the face plate is laterally covered, and the face plate is covered in one row horizontally on the face plate. A roof surface structure that supports plate-shaped roofing materials such as natural slate and tiles, and the face plate has a folded part that protrudes toward the eaves, and a folded part that folds down from the ridge side edge of the folded part. forming an overhang part consisting of a supporting part, fixing the folded part and the ridge side part of the roofing material with a fixture, and fixing the eave side part of the roofing material on the ridge side to the ridge side of the roofing material on the eave side. The fixing device is overlapped with the eaves side portion of the roof material on the ridge side and covered with the eave side portion.

[0008]

[Function] In the roof surface structure according to the present invention, for example, after covering a base member such as a metal rafter with face plates in the same manner as when roofing boards are laid horizontally, a layer of natural slate or the like is placed on each face plate. Support the roofing materials one by one in a horizontal row,
Fix the ridge side edge of the roofing material to the folded part of the overhang part provided on the face plate with a fixing device such as a tapping screw, and then attach the eave side part of the ridge side roofing material onto the ridge side edge of the eave side roofing material. A large number of roofing materials can be installed on the face plate by overlapping them and covering the fixing devices.

[0009] Therefore, the face plate has a relatively small area and is not heavy, and roofing materials can be carried onto the roof one piece or a few pieces at a time and fixed with fixing devices in one row horizontally to one face plate. By not handling large and heavy objects at high places, the work can be done relatively safely without requiring heavy labor.

[0010] The face plate may be a general roof plate having an engaging part on the ridge side and the eave side, with an overhang part provided thereon. The structure is simple because there is no need to provide a waste plate on the lower side of the opposite end, that is, on the indoor side, or to provide a water leakage prevention plate on the lower side of the face plate.

[0011] Even if water such as rainwater enters the indoor side of the roofing material through the gaps between the roofing materials, this water can be caught by the face plate and flowed down to the eaves side, and then drained from the eaves of the roof.
The ridge edge of the roofing material is fixed to the overhang part provided on the face plate using a fixing device, so even if water enters the indoor side from the top of the overhang part or the outer periphery of the fixing device, it will be caught by the face plate and will be prevented as described above. Since water can be discharged from the inside, it is possible to reliably prevent water from leaking to the indoor side of the face plate.
