[0002]

2. Description of the Related Art Conventionally, in this type of roof structure, for example, Japanese Utility Model Publication No. 64-57318 or Japanese Utility Model Publication No.
There is a structure having a structure using a natural slate roofing material as disclosed in Japanese Patent Publication No. 57320.

In such a conventional roof structure, the ridge-side end of the roofing material that is roofed on the base member is fixed by nailing, or the eaves-side end of the roofing material is supported by hooking. is doing.

[0004]

However, in the above-mentioned conventional structure, when the roofing material is roofed on the base member by nailing, the roofing material is easily broken by the impact of nailing, Since the sides are not fixed, if the roof material is subjected to negative pressure due to strong wind such as during a storm, it will easily float up.

Also, in the case of a supporting structure by hooking, the bending moment is large because the hook is cantilevered and has a long length, and when a negative pressure acts on the roofing material, as in the nailing method described above, Not only is it easily lifted up, but since the roofing material is supported at one point, it is easy to fall if the roofing material is broken.

Further, in order to prevent the intrusion of water from the vertical joints, it is necessary to increase the length of the roofing material in the vertical direction so that two or three sheets are stacked, which increases the material cost. There was such a problem.

An object of the present invention is to reliably prevent the roof material from falling due to cracking and rising due to the action of negative pressure.
Another object of the present invention is to provide a joint for a roof material and a roof structure using the joint, which can reduce the material cost by reducing the overlapping margin of the roof material.

[0008]

In order to solve the above problems, the first invention of the present application is a joint for laying and supporting a flat roof material such as natural slate or tile on a base member such as a purlin. In this joint, a ridge-side end is fixed on the base member, and a supporting substrate on which the abutting ends of roofing members that are laterally adjacent to each other are placed on the upper surface thereof, and the eaves of the supporting substrate. An engaging portion formed on a side end portion of the roof material for engaging and supporting the eaves side end portion, and a roof material formed under the engaging portion and placed on the support substrate. A fitting for a roofing material, comprising: a fitting portion into which a ridge-side end portion of the eaves-side roof material that vertically overlaps the eaves-side end portion is fitted and supported.

The second invention of the present application is that when a flat roof material such as a natural slate or tile is laid on a base member such as a main house via a joint for roofing, this joint has a ridge side end portion. Is fixed on the base member, and a supporting substrate on which the abutting ends of the roofing materials that are laterally adjacent to each other are placed on the upper surface thereof, and the above-mentioned each of the supporting substrates formed on the eaves side end of the supporting substrate. An engaging portion with which the eaves-side end portion of the roofing material is engaged and supported, and a longitudinal direction with respect to the eaves-side end portion of the roofing material formed under the engaging portion and placed on the supporting substrate. A ridge-side end of the eaves-side roofing material that overlaps with each other is fitted and supported, and each roofing material that is laterally adjacent to each other is butted on a support substrate of a joint fixed on the base member. Ends are placed, and the eaves-side ends of each of these roof members are connected to the support substrate. Together we are engaged with and supported on the engaging portion,
The roof structure is characterized in that the ridge-side end portions of the eaves-side roof material that vertically overlaps with the eaves-side end portion of the ridge-side roof material are inserted and supported in the insertion portion of the support substrate.

Since the ridge-side end of the roof is fitted and supported, water that intrudes from the vertical joints of the upper roof material that are laterally adjacent to each other is received by the joint and discharged from the lower roof material. , By this, over the entire length of the vertical joint, it is not necessary to extend the roof material of the lower tier, which is stacked under the roof material of the upper tier, to the ridge side, and it is possible to reduce the stacking margin of the roof material, Material cost can be reduced.

Further, since the roof material is supported through the joint fixed on the base member with screws, nails, etc., the roof material is not directly fixed with screws, nails, etc. As a result, the roof material will not be cracked by the impact of nailing as in the past.

Further, since the eave side end and the ridge side end of each roof material are supported by the engaging portion and the fitting portion at four points, the roof material is dropped due to cracking of the roof material, In addition, it is possible to prevent lifting due to the action of negative pressure that is exerted by strong wind during a storm.

Further, a locking tool projecting upward from between the abutting ends of the roof materials laterally adjacent to each other is provided near the central ridge side on the support substrate forming the joint, and the locking tool is provided. Since the eaves side end of the ridge side roof can be locked with, the eaves side end and the ridge side end of the roofing material per sheet are added in addition to the four-point support by the engaging part and the fitting part. The support to the section is 5 points, and it is possible to more reliably prevent lifting due to the action of negative pressure that is exerted by strong wind during a storm.

Further, a water stop piece is provided upright on the ridge-side end portion side on the support substrate forming the joint so that the ridge-side end portions of the roof materials adjacent to each other in the lateral direction abut. In addition, it is possible to increase the effect of stopping the water that enters from the vertical joints of the roof material toward the ridge side and prevent the roof material from slipping up.

Further, since the waterproof sheet is laid on the base member, even if the water intruding from the vertical joints of the roof material cannot be received on the joint during abnormal weather such as storm, it can be received on the waterproof sheet. In addition to being able to reliably discharge to the eaves side, it enhances watertightness even when rain is not enough due to design reasons, thereby increasing the degree of freedom in design.
