First, referring to FIGS. 2 and 3, the base member 30a is formed by bending a galvalume color steel plate, and has a rectangular shape in a plan view, a first fixing portion 31, and one end on the longitudinal side of the first fixing portion 31. A second fixed portion 32a that rises continuously from the portion 33 and is formed in an inverted L shape when viewed from the side surface so that the top surface portion 11 of the snow cover 10 can be placed, and the other end portion on the longitudinal side of the first fixed portion 31a. It includes a contact portion 35 that hangs diagonally downward from 34, and a mounting portion 37 that is continuous from the end portion 36 of the second fixing portion 32a and is formed in an L-shape in a side view. The first fixing portion 31 is formed with a hole 38 through which the fixing screw 41a described later is passed, and the upper surface of the second fixing portion 32a is formed with a screw hole 39a for receiving the machine screw 42a described later. Since the second fixing portion 32a is formed as described above, the upper surface of the second fixing portion 32a and the screw hole 39a are located above the first fixing portion 31, and the screw hole 39a is viewed in a plan view. Is located at a position deviated from the position of the hole 38. The effect of this configuration will be described later. The base member 30b also has the same configuration as the base member 30a.

Next, a method of attaching the snow cover 10 to the ventilation ridge 50 will be described with reference to FIGS. 3 to 5.

Prior to the description of the mounting method, first, the configuration of the ventilation ridge 50 will be described. The ventilation ridge 50 is a 1.5-inch type installed on a gable or a hipped roof, has a side view mountain shape as shown in FIG. 5, and is configured with the top portion of the ventilation ridge 50 as a boundary. It is symmetrical (the configuration on the right side, which is not shown in FIG. 5), is symmetrical on the left side). For convenience of explanation, only the configuration on the left side shown in FIG. 5 is shown in FIGS. 3 and 4. The ventilation ridge 50 has a plurality of ventilation holes 52 formed of cut-up holes on the upper surface 51, and a front plate portion 54 extending downward is formed on the eaves side end portion 53 of the upper surface 51.

When installing the ventilation ridge 50 on the roof, as shown in FIG. 5, the space 58 between the rafters 55a and 55b, the roof bases 56a and 56b, the roofing materials 57a and 57b, and the drainage 59a and 59b are provided. The ventilation ridge 50 is arranged on the upper surfaces of the roofing materials 57a and 57b so as to cover them.

Subsequently, the base member 30a is arranged at a position corresponding to the insertion hole 23a of the snow cover 10 without blocking the ventilation hole 52, and the contact portion 35 and the front plate portion 54 are brought into contact with each other and the mounting portion is placed. 37 is placed on the upper surface 51. In this state, the fixing screw 41a is driven from above the base member 30a through the hole 38 of the first fixing portion 31 so as to reach the rafter 55a through the upper surface 51, the roofing material 57a and the roof base 56a. , The base member 30a is fixed to the ventilation ridge 50, and the ventilation ridge 50 is fixed to the roof. When fixed in this way, the movement of the contact portion 35 is restricted by the front plate portion 54, so that it is easy to determine the arrangement position of the base member 30a, and the base member 30a may rotate around the fixing screw 41a. Since there is no base member 30a, the installation state of the base member 30a is stable. Further, the base member 30a and the ventilation ridge 50 can be fixed together at one time, which is convenient. Even in the base member 30a installed in this way, the hole 38 is located on the outer side of the screw hole 39a in a plan view, that is, the screw hole 39a and the hole 38 are displaced in the horizontal direction. The base member 30b is also fixed and installed in the ventilation ridge 50 using the fixing screw 41b at the same position and process as the base member 30a.

Next, the top surface portion 11 of the snow cover 10 is placed on the upper surface of the second fixing portion 32a of the base member 30a and the upper surface of the second fixing portion 32b of the base member 30b, and the ventilation hole 52 is covered with the top surface portion 11 to cover the front. The front hanging portions 19a and 19b are brought into contact with the face plate portion 54, and a part of the eaves side end portion 53 is covered with the front hanging portions 19a and 19b. Further, the positions of the insertion holes 23a and 23b are aligned with the screw holes 39a and 39b.

The dimensions of the insertion holes 23a and 23b are as described above, and the machine screws 42a or 42b can be inserted into the ventilation material 50 side. Machine screws 42a and 42b are inserted into such insertion holes 23a and 23b, respectively, screwed into the screw holes 39a and 39b, the machine screws 42a and 42b are lightly tightened, and the top surface portion 11 is temporarily fixed to the ventilation building 50. ..

Here, since the positions of the screw holes 39a and the holes 38 in the horizontal direction are displaced when the base member 30a is installed as described above, as shown in FIG. 5, the fixed portion of the base member 30a with respect to the top surface portion 11 And the fixed part with respect to the ventilation building 50 are separated. According to this structure, the insertion hole 23a is a fixed part of the top face portion 11, rainwater which has entered from a gap between the small screw 42a and screw holes 39a is, until the inside of the ventilation ridge 50 hardly penetrates. The same applies to the base member 30b.

Finally, the screws 43a and 43b are driven through the screw holes 24a and 24b from the outer surfaces of the anterior hanging portions 19a and 19b toward the ventilation ridge 50 so as to penetrate the ventilation ridge 50, respectively, and the snow cover 10 is fastened. After that, the machine screws 42a and 42b are fully tightened to complete the attachment of the snow cover 10 to the ventilation ridge 50.

With this configuration, the snow cover 10 can be fixed at the eaves side end portion 53 and the front plate portion 54 of the ventilation ridge 50, that is, at a location other than the upper surface 51 of the ventilation ridge 50. It can be fixed more robustly while preventing the ingress of rainwater.

When the snow cover 10 is attached to the ventilation ridge 50, the dimensions of the snow cover 10 and the base members 30a and 30b are set as described above. Therefore, as shown in FIG. 5, the snow cover 10 The front surface portion 13 of the above is located on the outer side of the eaves side end portion 53 and the front plate portion 54. Then, the first ventilation portion 21 is formed in the gap between the front surface portion 13, the eaves side end portion 53, and the front plate portion 54. By forming the first ventilation portion 21, a ventilation path 25 communicating the first ventilation portion 21 and the second ventilation portion 22 is formed above the upper surface 51 of the ventilation ridge 50, as shown by the dotted arrow in FIG. Air flows through. Therefore, the ventilation performance of the ventilation ridge 50 can be maintained even when it snows. Further, even if a load due to snow cover is applied to the top surface portion 11, the base members 30a and 30b suppress the deflection of the top surface portion 11, and the ventilation path 25 is not easily crushed.

As described above, the angle of the internal angle θ of the angle formed by the top surface portion 11 and the rear surface portion 15 of the snow cover 10 is set to 90 °. Therefore, when the snow cover 10 is attached, the rear surface portion 15 stands upright with respect to the upper surface 51 of the ventilation ridge 50 and is inclined with respect to the horizontal direction. With this configuration, it is difficult for snow to accumulate on the rear surface portion 15, and it is difficult for the second ventilation portion 22 to be buried by snow. Further, since the distance between the top surface portion 11 and the upper surface 51 of the ventilation ridge 50 is the same as the length of the short side of the rear surface portion 15, that is, the longest, the ventilation path 25 is widened and the ventilation is good.

Further, since the formation range of the second ventilation portion 22 straddles the rear surface portion 15 and the top surface portion 11, the second ventilation portion 22 is also formed at the farthest position in the vertical distance between the snow cover 10 and the upper surface 51. There is. With this configuration, the snow height required to fill all of the second ventilation section 22 becomes high, and even if either the rear surface portion 15 or the top surface portion 11 is buried by the snow cover, the other must not be buried. Since the second ventilation portion 22 is not completely buried, the second snow cover portion 22 is less likely to be buried due to the snow cover.
