Description

  The present invention relates to a fastening structure and a fastening method for a roof material to be constructed on a roof base.

Conventionally, a roof is formed by constructing a roof material formed of a thin flat plate-like inorganic plate on a roof base such as a field plate (for example, see Patent Document 1). As shown in FIG. 10, the roofing material 1 is formed of a thin cement-based inorganic board or the like, and a plurality of nail holes 20 are formed so as to penetrate vertically. Then, the roof material 1 can be fixed to the roof base 4 by driving a dedicated nail 21 or screw 22 through the nail hole 20 into the roof base as a fixture 3. In this way, a plurality of roofing materials 1, 1... Can be laid in the direction of the eaves to form a roof. However, the adjacent roofing materials 1, 1 adjacent to each other in the direction of the eaves are overlapped and arranged. Is. That is, in the case shown in FIG. 11A, the roofing material 1A is fixed with the nail 21, but the eaves side end portion 1a of the roofing material 1A is disposed closer to the eaves side than the roofing material 1A. It is placed on the ridge side end 1b of the roofing material 1B. Moreover, the eaves side edge part 1a of the roofing material 1C arrange | positioned rather than the roofing material 1A is mounted on said roofing material 1A. In this case, in order to obtain waterproofness and the like, the nail 21 of the roof material 1A is placed so as to be covered with the roof material 1C on the ridge side. The same applies to the case where screws 22 are used as shown in FIG. Thus, since the roofing material 1 is piled up on the fixture 3, the upper surface of the head 5 of the fixture 3 is made to be a dedicated one that is formed flat.

  However, in the above-described conventional example, it is necessary to carefully fasten the head 5 of the fixture 3 so as to be substantially parallel (horizontal) to the flat upper surface of the roofing material 1. Since it is difficult to fasten 3 accurately, as shown in FIGS. 12 (a) and 12 (b), when the fixture 3 is in an inclined construction state, the head 5 of the fixture 3 is lifted, and the roofing material is In some cases, problems such as cracking at the fastening portion or opening of the roof material (a gap is formed between the upper and lower roof materials) may occur. In addition, since a dedicated fixture 3 is required, the cost for the procurement may be high. Moreover, when the holding force of the roofing material 1 requested | required with the exclusive fixing tool 3 is not obtained, construction cannot be performed, and when it is used forcibly, there is a possibility that problems such as scattering of the roofing material may occur.

  The present invention has been made in view of the above points, and there is no problem even if the fixing tool is driven obliquely, and the roof material fixing structure does not particularly require a dedicated fixing tool. It aims at providing the fastening method of a roofing material.

The roofing material 1 can be formed in a substantially rectangular shape that is long in the width direction in plan view, and the roofing material 1 is formed with a plurality of mounting holes 30, 30. Each mounting hole 30 is located at a substantially central portion in the short direction of the roofing material 1 and is provided so as to penetrate the roofing material 1 up and down.

  The pressing member 2 used in the present invention is a molded product of metal or resin, and is formed in a cross-section inverted hat shape. That is, as shown in FIGS. 1A and 1B, the pressing member 2 includes a flat bottom portion 31, a rising portion 32 that protrudes upward along the outer periphery of the bottom portion 31, and a rising portion. The pressing piece 6 is formed to protrude outward from the upper end of the portion 32 (on the side opposite to the bottom portion 31). The bottom 31 is formed with a fastening hole 33 penetrating vertically at a substantially central portion. In addition, the outer diameter of the raised portion 32 is slightly smaller than the diameter of the mounting hole 30 of the roof material 1. The distance from the bottom surface of the bottom 31 to the bottom surface of the pressing piece 6 is formed to be substantially the same as the thickness of the roofing material 1.

  The fixing tool 3 may be a nail or a screw dedicated to fastening the roofing material 1 as in the prior art, but it is not necessary to use a special one.

  And when fastening the said roofing material 1 to the roof base | substrates 4, such as a field board, it carries out as follows. First, the pressing member 2 is attached to the attachment hole 30 of the roof material 1. At this time, the rising portion 32 of the pressing member 2 is fitted into the mounting hole 30 as shown in FIG. 3A, and the pressing piece 6 is locked to the upper opening edge of the mounting hole 30 as shown in FIG.

In the case of installation at the construction site, the cost of installation (equipment (adhered)) at the manufacturing plant can be reduced, but the labor at the construction site increases. There are opposite merits and demerits when installing in a manufacturing factory.

  Next, as shown in FIGS. 1A and 1B, the roof material 1 to which the pressing member 2 is attached is placed on the roof base 4. At this time, the eaves side end of the roof material 1 (1A) (from the mounting hole 30) is placed on the ridge side end 1b of the eaves side roofing material 1 (1B) previously fastened on the roof base 4. Eaves side) 1a is placed. Next, the fixing member 3 is driven into the roof base 4 through the fastening hole 33 of the pressing member 2 provided in the roofing material 1 (1A), so that the roofing material 1 (1A) is pressed from above with the pressing piece 6 of the pressing member 2. Press down and fix. At this time, the head 5 of the fixture 3 is housed inside the rising portion 32. Accordingly, the outer diameter of the head 5 of the fixture 3 is smaller than the inner diameter of the raised portion 32, and the height of the head 5 of the fixture 3 is smaller than the height of the raised portion 32. ing. Further, even when the fixture 3 is driven obliquely, the height and the head of the rising portion 32 are prevented so that the head 5 of the fixture 3 is accommodated inside the rising portion 32 and does not protrude upward. A size of 5 is set. The outer diameter of the hammer for driving the fixture 3 is preferably smaller than the inner diameter of the rising portion 32.

  Next, the eaves side end portion 1a of another roof material 1 (1C) disposed on the ridge side of the roof material 1A is placed on the roof material 1 (1A) fastened with the fixture 3. In this case, in order to obtain waterproofness and the like, the fixture 3 of the roof material 1 (1A) is covered with the roof material 1 (1C) on the ridge side. Thus, the roof can be formed by sequentially constructing a plurality of roof materials 1, 1,.

  And in this invention, as shown to FIG. 1 (a) (b), the head 5 of the fixing tool 3 does not fit in the thickness of the roofing material 1 by the pressing member 2, and it becomes a protrusion, but it is a roofing material. It is possible to prevent problems such as cracking 1 at the fastening portion or opening of the tip of the roofing material 1 (a gap is formed between the upper and lower roofing materials 1 and 1). Therefore, it is not necessary to have a severe requirement to drive all the fixtures 3 so as not to tilt at the construction site, and the workability can be improved. In addition, even if a normal fixture 3 is used, the roofing material 1 can be securely and firmly fixed by the pressing member 2, and the wind resistance can be improved and the fixing that can be used is also possible.
