Description

  The present invention relates to a method for attaching a roofing material, and more specifically, even when the main building material or the like is slightly deformed, the roofing material can be easily positioned and attached to the main building material so as not to be displaced. Further, the present invention relates to a method for attaching a roof material having good workability.

  Conventionally, when the existing old roofing material is removed and the new roofing material is attached to the existing main building, the main building is used as the standard for the roofing material. It is common to connect roof materials in order while positioning the parts together and attach the roof material to the main building with fasteners or the like. And the cover material (what is called keraba) which covers the outer end of a roofing material is fixed to the both ends of a roofing material, and the rain gutter is provided along the edge part of the underwater side of a roofing material.

  In addition, as another method of attaching roofing materials, for example, roofing materials having rising edges at both ends are arranged on the main building material, and the rising edges of adjacent roofing materials are connected by a connecting fixture fixed to the main building material. A fixing method is also known in which a rising U is covered with an inverted U-shaped cap material and the engaging edge at the lower end of the cap material is engaged with a connecting fixture (Patent Document 1).

  However, as in the conventional method of attaching roofing materials, the base material on the water side or the water side is used as a reference, and the part that becomes the reference of the roof material is aligned with the water material on the water side or the water side. When installing the roofing material while positioning the roofing material, if the existing waterside or waterside main building or the beam material that supports it is slightly deformed due to bending or other reasons, the mounting criteria will be unclear and distorted. Therefore, as the roof material is attached while being connected from one end side to the other end side of the main building material, the roof material is gradually displaced, and when it is installed to the other end side of the main building material, the roof material There was a risk that the position of would be greatly misaligned. In order to eliminate such misalignment, it is necessary to correct the mounting position each time the roofing material is attached one by one, but the work of attaching the roofing material while correcting the mounting position one by one is accurate. Since there is no standard, there is a problem that it is not easy and is troublesome and inferior in workability.

  The problem of the positional deviation of the roof material as described above cannot be solved even if the roof material mounting method of Patent Document 1 is adopted.

  The present invention has been made under the circumstances described above, and the problem to be solved is to easily and accurately position the roofing material so that the roofing material is not misaligned even when the main building material is somewhat deformed. Then, it is providing the attachment method of the roof material with favorable workability which can be attached to a main building material.

  In order to solve the above-mentioned problem, a roof material mounting method according to the present invention is a method of mounting a plurality of roof materials on a plurality of purlin materials while overlapping and connecting the end portions thereof, and in the length direction of the purlin materials. Two cover members that cover the outer edges of the roofing material that are attached to both ends are fixed to both ends in the longitudinal direction of the main building, and a water string is stretched between the opposing portions of both cover members. In addition, a plurality of roofing materials are attached to the purlin material while being connected in the length direction of the purlin material, with the mark portion serving as a reference for attaching the roofing material being aligned with the water thread.

  In the method for attaching the roofing material of the present invention, the water material is stretched between the ends of the two water members facing each other or between the water-side ends, and It is desirable to match the water yarn with the end on the side or the end on the underwater as a mark.

  Further, the roofing material has a wide ridge at one end and a narrow ridge at the other end, and the wide ridge at one end is connected to the other end of the adjacent roofing material. When overlapping and connecting the narrow peaks of the roof, the width of the roof material is corrected by adjusting the overlapping position of the wide peaks within the range of the gap between the peaks. It is also desirable to do.

  As in the method of attaching the roofing material according to the present invention, before attaching the roofing material, the two cover members covering the outer end of the roofing material are fixed to both ends in the longitudinal direction of the main building material, If the water yarn is stretched between the opposite locations and stretched, when the roofing material is installed, the above water yarn can be used as a reference without using the purlin material as a reference, so the reference line for the installation position is clear By aligning the mark of the roofing material with this water thread, all roofing materials are easily and accurately positioned so as not to be misaligned, and are connected to the purlining material in the longitudinal direction of the purlining material. It becomes possible. Therefore, the problem of the positional deviation of the roof material described above can be solved, and the workability can be greatly improved.

  And, a water string is stretched between the opposite water-side ends or the water-side ends of the two cover members, and the water-side edge or the water-side edge of the roofing material is a mark portion. As a result, it is not necessary to provide a mark on the roofing material, and because the end of the upper or lower side of the roofing material is easy to match with the water yarn, the positioning of the roofing material is easier. Thus, the roofing material can be positioned and attached more accurately and quickly.

  Further, the roofing material has a wide ridge at one end and a narrow ridge at the other end, and the wide ridge at one end is connected to the other end of the adjacent roofing material. When overlapping and connecting the narrow peaks of the roof, the width of the roof material is corrected by adjusting the overlapping position of the wide peaks within the range of the gap between the peaks. Then, the positional deviation of the width direction of a roofing material can be adjusted easily and reliably, and also the relative angle adjustment of the adjacent roofing material can also be performed.

It is an end view of the longitudinal direction one end of the roof material used for the attachment method of the roof material which concerns on the embodiment.

  Hereinafter, with reference to drawings, the embodiment of the attachment method of the roof material concerning the present invention is described in detail.

  FIGS. 1 to 3 sequentially explain a method of attaching a roof material according to an embodiment of the present invention, and FIG. 1 is a perspective view showing two cover members fixed to both ends of a main building material, FIG. 2 is a perspective view showing a state in which a water string is stretched between opposite ends of both cover members opposite to each other, and FIG. It is the perspective view shown where a plurality of roofing materials are connected and attached to the purlin material while matching the water thread.

  The method of attaching the roofing material of this embodiment is an example in which the roofing material of an existing bicycle parking lot is peeled off and replaced with a new roofing material, and the old roofing material has already been repaired as shown in FIG. A plurality of (three) purlins 1 are exposed. The left and right beam members 2 supporting the main building material 1 are fixed to the upper ends of the left and right columns 3 so as to be inclined toward the column 3 so as to have a flow gradient. θ is an obtuse angle. The respective purlin members 1 are arranged and fixed on the left and right beam members 2 so as to be parallel to each other and perpendicular to the left and right beam members 2, but in this embodiment, It is assumed that the lower side (support side) purlin 1 is slightly bent and deformed upward for some reason. Therefore, when attaching the roofing material based on the bent waterside main building 1, it is difficult to accurately position the roofing material while correcting the position of the roofing material, and thus there is a risk of displacement in the roofing material. There is.

  Therefore, according to the method of attaching the roofing material of this embodiment, as shown in FIGS. 1 and 2, before attaching the roofing material, first, two cover members 4, 4 is fixed. As shown in FIGS. 4 and 5, the cover member 4 has a substantially U-shaped cross-sectional shape so as to surround the outer ends of the roof material 5 attached to both ends in the longitudinal direction of the purlin material 1. It is a member and is called “Keraba”. These cover members 4 and 4 are roofs so as to cover the outer ends of the roofing material 5 located at both left and right ends after the roofing material 5 is attached to the main building material 1 in the conventional method of attaching the roofing material. Although fixed to both ends of the material 5 and the purlin material 1, in the present invention, the cover members 4, 4 are fixed to both ends of the purlin material 1 before the roof material 5 is attached as described above.

  The left and right cover members 4, 4 are attached so that the left and right cover members 4, 4 are parallel to each other and have a line-symmetrical positional relationship with each other, and are perpendicular to the main building material 1. As shown in FIGS. 4 and 5, the overlap margin 4 a of the cover member 4 is overlapped on the upper surface of both ends of the purlin member 1 and a fastener such as a pan drill screw 7 a is arranged. Do by fixing with. However, the right and left cover members 4 and 4 are not strictly perpendicular to the bent main body 1 on the underwater side, but the above “so that it is perpendicular to the main house 1” means that The meaning content includes a case where the angle is not exactly a right angle. Further, when the bending deformation of the underwater purlin material 1 is slightly larger, the cover members 4 and 4 are arranged in parallel, and the overlap margin 4a of the cover members 4 and 4 is set to both ends of the underwater purlin material 1. In such a case, it is difficult to attach the cover members 4 and 4 to each other. The mutual interval between the lower end portions may be made slightly narrower than the mutual interval between the water-side end portions, and the overlap margin 4a of the cover members 4 and 4 may be attached to be overlapped with both end portions of the water-side purlin 1. . As described above, the phrase “so as to be parallel to each other” described above includes meanings that include cases where they are not strictly parallel.

  When the attachment of the left and right cover members 4 and 4 is finished, as shown in FIG. 2, the water thread 6 is stretched between the opposite ends of the left and right cover members 4 and 4 and stretched. Clarify the reference line when attaching the roofing material 5. The water yarn 6 may be stretched between the opposite water-side ends of the left and right cover members 4, 4 or between the opposite intermediate portions of the left and right cover members 4, 4. May be. In short, the water thread 6 may be stretched between the left and right cover members 4, 4 so as to form a clear reference line when the roofing material 5 is attached. is there.

  When the installation of the water thread 6 is finished, as shown in FIG. 3, the underwater end 5a of the roofing material 5 is used as a mark as a reference for attachment, and the underwater end 5a of the roofing material 5 is The roof material 5 is attached to the purlin material 1 while connecting a plurality of roof materials 5 in the length direction of the purlin material 1 in accordance with the water thread 6. When the water thread 6 is stretched between the water-side ends of the left and right cover members 4, 4, the roof material 5 is attached with the water-side end of the roof material 5 as a mark. It may be performed while matching the yarn 6, and when the water yarn 6 is stretched between the opposed intermediate portions of the left and right cover members 4, 4, it is provided at the intermediate portion in the longitudinal direction of the roof material 5. What is necessary is just to carry out, aligning a mark part with a water thread.

  Water strings 6 are stretched between the water-side ends of the left and right cover members 4, 4 or between the water-side ends, and the water-side end 5 a or the water-side end of the roofing material 5 is In the case of matching with the yarn 6, it is not necessary to provide a mark portion on the roofing material 5 and the end portion on the lower side or the upper side of the roofing material 5 is easy to match with the water yarn. It becomes easy, and the roofing material 5 can be positioned and attached more accurately and quickly. In particular, as in this embodiment, when aligning the underwater end portion 5a of the roofing material 5 with the water string 6 stretched between the underwater end portions of the left and right cover members 4, 4, the working position This is preferable because there is an advantage that the positioning workability is further improved.

  In addition, as a mark part of the roofing material 5, in addition to the above-mentioned water-side or water-side end of the roofing material 5, for example, a low-adhesive tape that is detachably attached to the roofing material 5, Marks and lines written with marking pens and other writing tools, pilot holes formed in the roofing material 5 in order to insert fasteners can be used.

  As shown in FIG. 7, the roofing material 5 used in this embodiment has a wide trapezoidal mountain portion 51 at one side end (left side end) over the entire length of the roofing material, and the other side end (right side end). ) Has a trapezoidal peak 52 that is narrower than the peak 51 over the entire length of the roofing material, and one or more trapezoidal peaks 53 that are narrower in the middle in the width direction over the entire length of the roofing material. (2) It has and is fixed to the purlin 1 in the following manner.

  That is, the first roofing material 5 that is first attached to the main building 1 is as described above in a state in which the wide crest 51 at the left end is inserted into the left cover member 4 approximately half as shown in FIG. The end 5a on the underwater side of the roofing material 5 is positioned according to the water thread 6, and the round packing 8a and the washer 9 are overlaid on the prepared hole formed in the vicinity of the peak 51, and above that Then, a fastener such as a drill screw 7b is screwed into the purlin 1 and, further, a sleeve-like packing 8b is inserted into a pilot hole formed in the peak portion 53 in the middle of the roofing material 5, and a washer 9 is stacked. A fastener such as a drill screw 7b is screwed into the purlin member 1 from above to fix it to the end of the purlin member 1 near the left end. The sleeve-shaped packing 8b is provided with a flange portion at the upper end of the cylindrical sleeve. The flange portion presses the peak portion 53 of the roofing material 5 and supports the head of the drill screw 7b to have a screw-in dimension. It plays the role of making it constant.

  When the fixing of the first roofing material 5 is finished, as shown in FIGS. 3 and 6, the wide mountain portion 51 at the left end of the second roofing material 5 is changed to the narrow width at the right end of the first roofing material 5. The first roofing material 5 and the second roofing material 5 are connected to each other while the end portion 5a on the lower side of the second roofing material 5 is positioned according to the water thread 6 while being stacked on the mountain portion 52 of the second roofing material 5. . Then, as shown in FIG. 6, the mountain-shaped cover member 10 (which has a trapezoidal cross section and has the same length as the entire length of the roofing material 5) is placed on the wide mountain portion 51 of the connecting portion and is slightly larger than the mountain portion 51. A sleeve-shaped packing 8b is inserted into pilot holes respectively formed in the mountain-shaped cover member 10, the wide mountain portion 51, and the narrow mountain portion 52, and a washer 9 is stacked thereon. Then, the connecting portion of the roof materials 5 and 5 is fixed to the purlin material 1 by screwing the drill screw 7b into the main material 1 from above. And the peak part 53 of the intermediate part of the roof material 5 of the 2nd sheet | seat is also fixed to the base material 1 using the sleeve-shaped packing 8b, the washer 9, and the drill screw 7b similarly to the above. In addition, in FIG. 3, the mountain-shaped cover member 10 covered on the mountain part 51 of a connection part is not illustrated.

  The third and subsequent roof materials 5 are connected while being positioned in the same manner as described above, and the connecting portion of the roof material 5 covered with the mountain-shaped cover member 10 using the sleeve-shaped packing 8b, the washer 9, and the drill screw 7b. And the mountain part 53 of the intermediate part of the roofing material 5 is fixed to the main building material 1.
