Description

  The present invention relates to a roofing structure using a flat roof material.

  When roofing is performed using a flat roof material such as a flat slate, a method of arranging the roof material in a staggered manner is generally used (see, for example, Patent Document 1).

  FIG. 6 shows an example of construction in which the roofing material 1 is arranged in a staggered manner, and the roofing material 1 is formed in a substantially rectangular shape. Then, as shown in FIG. 6A, the roofing materials 1 adjacent in the direction parallel to the eaves are arranged such that the side edges thereof are in contact with each other, and the roofing material 1 adjacent in the eaves building direction is the roof on the eaves side. The eaves-side end portion of the ridge-side roofing material 1 is arranged on the ridge-side end portion of the material 1. At this time, the top of the eaves-side roofing material 1 is positioned so that the butted end of the roofing material 1 adjacent in the direction parallel to the eaves is located in the center in the width direction parallel to the eaves of the eaves-side roofing material 1 The roof material 1 can be arranged in a staggered manner by superimposing the roof material 1 on the building side.

JP 2001-98704 A

  When the roofing material 1 is arranged in a staggered manner and the roofing material 1 is piled up in the direction of the eaves, the butted ends of the roofing materials 1 adjacent to each other in the direction parallel to the eaves are shown in FIG. As shown in Fig. 4, the positions are positioned on a straight line every other stage. That is, FIG. 6C is a cross-sectional view showing a state in which the roofing material 1 is applied to the upper surface of the base plate 7 stretched on the rafter 6, and as seen in this figure, three steps in the eaves-ridge direction are shown. The butt end of the lower roof material 1b is located below the central portion of the central roof material 1a, and above the central portion of the central roof material 1a. In addition, the butt end of the upper roof material 1c is located, and the butt edge of the lower roof material 1b and the butt edge of the upper roof material 1c are the roof of the center step. It will correspond in the center part of the material 1a.

  In this case, when a load is applied as indicated by the arrow B in FIG. 6C when an operator gets on the butted end portion of the upper roof material 1c during construction, the upper roof material 1c The side end portion is bent and deformed downward, and a force acts so as to be bent downward at the center portion of the middle roof material 1a. However, only the side end of the lower roofing material 1b is located below the central part of the middle roofing material 1a, and acts to bend downward to the central part of the middle roofing material 1a. Therefore, the lower roofing material 1b cannot receive a strong force, and the deformation of the middle roofing material 1a cannot be suppressed. For this reason, the problem that it is easy to generate | occur | produce a vertical crack in the center part of the roof material 1a of the middle step arose.

  In particular, when the central portion of the roof material 1a at the middle stage is located between the rafters 6 and 6 as shown in FIG. Cracks are likely to occur. In particular, a low quality base plate 7 is often used recently due to the effects of soaring timber. In this case, the base plate 7 is easily bent and deformed with respect to the load, so that the roof material 1a is cracked. It was more likely to occur.

  This invention is made | formed in view of said point, and it aims at providing the roofing structure which can suppress that a crack arises in a roof material at the time of construction.

  Embodiments of the present invention will be described below.

  FIG. 2A shows an example of the roofing material 1 used in the present invention, which is made of a flat plate made of a ceramic hydraulic material such as a flat plate slate. The roofing material 1 is formed in a substantially rectangular shape that is slightly longer in the width direction (the direction parallel to the eaves), and a notch portion 2 is provided at each side end portion at the ridge side end portion. The notch 2 is formed so as to be opened at two sides in the ridge direction and the side direction, and the inner side edge is formed as an inclined side. Therefore, by providing the notches 2 on the left and right sides of the roofing material 1 in this way, the trapezoidal protrusion 10 is formed at the center of the ridge side end of the roofing material 1. Reference numeral 14 denotes a nail hole provided in the roofing material 1.

  FIG. 2B shows an example of the backing reinforcing material 3 used in the present invention, which is made of a flat plate of a ceramic hydraulic material such as a flat plate slate. The lining reinforcing material 3 is formed in a trapezoidal shape with a short side on the eaves side and a long side on the ridge side.

  The roof material 1 is formed by molding a molding material mainly composed of a hydraulic material such as cement into a long sheet, and cutting the long belt-like sheet-shaped molding material 4 into a predetermined shape. After the roof molding material 11 having the same shape is produced, the roof molding material 11 can be produced by curing and curing. FIG. 3 shows a step of cutting the sheet-shaped molding material 4 to obtain the roof molding material 11, and the roof molding materials 11 are taken in two rows along the longitudinal direction of the sheet-shaped molding material 4. . When the roof molding material 11 is cut from the sheet-shaped molding material 4 and removed, the part of the notch 2 of the roof molding material 11 remains, but the two rows of the roof molding material 11 face each projecting portion 10 part. The portion of the notch 2 of the roof molding material 11 remains as a hexagon between the two roof molding materials 11 in two rows. When this hexagonal portion is cut in half at the center along the longitudinal direction of the sheet-shaped molding material 4, a backing reinforcement molding material 12 having the same shape and the same size as the backing reinforcement material 3 can be obtained. The roofing material 1 and the backing reinforcing material 3 can be manufactured by curing and curing the roofing molding material 11 and the backing reinforcement molding material 12 obtained by cutting the sheet-like molding material 4 in this way. As described above, the backing reinforcing material 3 can be manufactured by using a part of the sheet-like molded material 4 that remains after cutting to form the cutout portion 2 in the roofing material 1. It is not necessary to use a special material separately to manufacture the film.

  When the backing reinforcing material 3 is produced in this way, it is formed of the same material as that of the roofing material 1, but is not limited to this. When the lining reinforcing material 3 is formed of a material different from the roofing material 1, the lining reinforcing material 3 is covered with the roofing material 1 and not exposed to the surface, in addition to being formed of non-combustible material such as iron, aluminum, and ceramics. It can also be made of any material that is not incombustible, such as plastic, recycled plastic, paper or waste paper hardened, wood, wood hardened.

  Next, roofing construction in which the roofing material 1 and the backing reinforcing material 3 are lined up on a roof base plate will be described. The roofing materials 1 are arranged side by side in a state parallel to the eaves with their side end faces butted against each other, and are nailed to the base plate through the nail holes 14 provided in each roofing material 1. By doing so, it is fixed. Thus, when the roofing material 1 is arranged in a direction parallel to the eaves, the notches 2 on both sides of the roofing material 1 that are adjacent to each other coincide with the trapezoidal shape as shown in FIG. And the backing reinforcement material 3 is arrange | positioned so that it may straddle between the notch parts 2 corresponding to this trapezoid shape, and it may fit. As described above, the backing reinforcing material 3 is made of the sheet-shaped molding material 4 that is cut to form the notch 2 in the roof material 1, and the notch portions 2 on both sides of the adjacent roof material 1 are formed. It is formed in the same shape and size as the trapezoidal shape formed in conformity. For this reason, the backing reinforcing material 3 can be fitted into the cutout portion 2 and arranged without causing a large gap with the roofing material 1. The backing material 3 does not need to be particularly fixed, but may be nail-fixed to the base plate as necessary.

  After the roof material 1 is installed in a direction parallel to the eave as described above, the roof material 1 is installed on the ridge side of the roof material 1 after the first-stage roof material 1 is constructed. In the same manner as described above, the backing reinforcing material 3 is fitted and arranged so as to straddle the notch 2 of the adjacent roofing material 1. In attaching the second-stage roof material 1 in this manner, the first-stage roof material 1 and the second-stage roof material 1 adjacent to each other in the eaves-ridge direction are placed on the ridge side end of the first-stage roof material 1. The eaves side end portions of the roof material 1 of the step are arranged so as to overlap each other, and the nail holes 14 of the roof material 1 of the first step are covered with the roof material 1 of the second step. At this time, when the second-stage roofing material 1 is arranged side by side in a direction parallel to the eaves, the butted end portion of the second-stage roofing material 1 is the first-stage roofing material as shown in FIG. The second-stage roof material 1 is overlaid on the first-stage roof material 1 so as to be positioned at the center of the width direction 1 (the direction parallel to the eaves).

  After the second-stage roof material 1 is thus constructed, the third-stage roof material 1 and the backing reinforcement material 3 are similarly constructed. The third level roofing material 1 is performed in the same manner as the construction of the second level roofing material 1 with respect to the first level roofing material 1 described above, and the third level roofing material 1 is parallel to the eaves. 1C, the butt end portion of the third-stage roof material 1 is positioned at the center in the width direction of the second-stage roof material 1, as shown in FIG. The roof material 1 of the third step is overlaid on the roof material 1.

  Similarly, roofing work can be performed by arranging the roofing materials 1 in a larger number of steps. And as mentioned above, on the roof material 1 on the eaves side, the butt end portion of the roof material 1 adjacent to the eaves in the direction parallel to the eaves is located in the center in the width direction of the roof material 1 on the eaves side. By stacking the roof material 1 on the ridge side, the roof material 1 can be arranged in a staggered manner. At this time, when the roofing materials 1 are arranged in a staggered manner in this manner and the roofing materials 1 are stacked in the direction of the eaves, the butted ends of the roofing materials 1 adjacent to each other in the direction parallel to the eaves are straightened every other step. It will be located on the line. That is, as shown in FIG. 1 (c) in which the roof material 1 is constructed on the third level, the butted end portion of the first level roof material 1b is located under the center of the second level roof material 1a. Further, the butted end portion of the third-stage roofing material 1c is located on the center portion of the second-stage roofing material 1a. The butt end portion of the roofing material 1c coincides vertically with the center of the second-tier roofing material 1a.

  Thus, in the center part of the roofing material 1a, when the butted end portion of the lower roofing material 1b and the butting end portion of the upper roofing material 1c are aligned with each other as shown in FIG. In addition, if the operator's weight or the like acts as a load during construction, the roof material 1a is likely to crack. However, as described above, the lining reinforcing material 3 is disposed across the notch 2 of the adjacent roof material 1b in the lower stage, and the lining reinforcing material 3 is located on the lower surface of the central portion of the roof material 1a. Therefore, even if the weight of the operator acts as a load at the time of construction and a force for bending and deforming downward is applied to the central part of the roofing material 1a, the lining reinforcing material 3 is provided below the central part of the roofing material 1a. It is arranged, and this force is received by the backing reinforcing material 3 so that the central portion of the roofing material 1a can be prevented from being bent downward and deformed, and cracks are generated in the roofing material 1a. It can be prevented.

  And as seen in FIG. 1 (c), in all the roofing materials 1 that are mounted on the eaves-side roofing material 1, the lining reinforcing material 3 is disposed below the central portion. All the roofing materials 1 can be reinforced with the backing reinforcing material 3, and the roofing material 1 can be prevented from cracking during construction.

  In the embodiment shown in FIGS. 1 and 2 described above, the backing reinforcing material 3 is formed in a trapezoidal shape. However, the present invention is not limited to this. For example, in the embodiment of FIG. 4, the notch 2 provided in the roofing material 1 is formed in a triangle, and the notch 2 of the roofing material 1 adjacent to the side matches the triangle shape. The backing reinforcing material 3 arranged so as to straddle between the two is also formed in a triangle. In the embodiment of FIG. 4 (a), the cutouts 2 are formed small on both side ends of the roofing material 1, and the backing reinforcing material 3 is formed in a small triangular shape. On the other hand, in the embodiment of FIG. 4B, the overall shape of the roofing material 1 is formed in a pentagonal shape by forming the triangular notch 2 large, and the backing reinforcing material 3 is also in a large triangular shape. It is formed.

  Further, the backing reinforcing material 3 is formed in the same shape as the notched portion 2 of the roof material 1 adjacent to the side, and the backing reinforcing material 3 of the backing reinforcing material 3 as shown in FIG. 4 (c) and FIG. 4 (d). You may form in the shape where the edge part on the ridge side protrudes from the notch part 2 to the ridge side. In this way, if the backing reinforcing material 3 is formed so as to protrude from the notch 2 to the ridge side, the roofing material 1 placed on the backing reinforcing material 3 can be reinforced in a wide area. The reinforcement effect by the backing reinforcing material 3 can be obtained high.

  FIG. 5A is a cross-sectional view showing a state in which the roofing material 1 is wound on the base plate 7. The roofing material 1 overlaps the eaves-side end of the roofing material 1 on the building-side end of the roofing material 1 on the eaves-side end of the roofing material 1. A gap having a long and narrow triangular shape (wedge shape) is formed between the upper surface of the base plate 7. Therefore, if the above-mentioned lining reinforcing material 3 is formed in the same cross-sectional shape as the triangular shape (wedge shape) of this gap as shown in FIG. 5B, the lining reinforcing material 3 is used between the roof material 1 and the base plate 7. This is preferable because the gap can be filled. Of course, the backing reinforcing material 3 may be formed in a rectangular cross section having a constant thickness as shown in FIG.
