Description

  The present invention relates to a roof fixing device used for installing a roof installation body such as a solar cell module on a roof of a house, and is particularly fixed to a roof base material through a hole formed in a roof tile material. The present invention relates to a roof fixing device having a structure.

  In recent years, with the spread of solar power generation, solar energy utilization devices such as solar cell modules are often installed on the roofs of houses. In general, such a solar cell module used for industrial and household purposes is formed by integrally providing a plurality of solar cell elements connected in series or in parallel on a translucent substrate made of glass, resin, or the like. It is configured by housing the optical substrate in a frame. And, by fastening or tightening the bolts and screws inserted into the through holes and screw holes formed in the frame with respect to the rails and support brackets installed on the roof of the house, the solar cell module is Fixed on the roof of the house. In addition to solar cell modules, solar water heaters are widely known as solar energy utilization devices that use solar energy, and the same method can be used for mounting various types of solar energy utilization devices on the roof. Is used. In the present specification, a machine, device, equipment, or the like installed on a roof such as a solar energy utilization device is referred to as a roof installation body, and rails and support brackets provided for installing the roof installation body on the roof. Etc. will be referred to as attachment members.

  When a roof installation body such as a solar cell module is attached to a roof having an inclination on the house roof, it is necessary to firmly attach the roof installation body to a strong wind such as a typhoon. However, the tile material laid on the inclined roof does not have a strength capable of supporting a heavy roof installation body such as a solar cell module, and if a force exceeding a predetermined force is applied, It may break or tiles may fall off the roof. Therefore, in order to firmly fix the roof installation body on the roof of the house, a mounting member provided as a rail or a support metal fitting for installing the roof installation body on the roof is formed from a wooden board, plywood or the like. It is necessary to fix through a fixing device to a roof base material called a field plate, a rafter formed from a thin wooden pillar, a metal pillar, or the like and supporting the base material.

  Below, the example of the structure which fixes a solar cell module on the roof comprised by laying a tile material is demonstrated. FIG. 9 is a diagram illustrating an example of the structure of a conventional roof fixing device. In this structure, a mounting member such as a rail is supported by a fixing metal fitting 102 fixed to the base material 101 of the roof, and the solar cell module is installed on the roof. When installing the fixing metal fitting 102, first, the tile material 103b adjacent to the tile material 103a to which the fixing metal fitting 102 is attached is lifted, and the tile material 103a is pulled out. Then, a wooden base plate 104 is arranged on the base material 101 located below the roof tile 103a, and the base plate 104 is fixed to the base material 101 using screws, nails or the like. Next, the fixing bracket 102 is fixed to the base plate 104 using screws, nails or the like, the tile material 103a that has been pulled out is returned to its original position, and then the tile material 103b that has been lifted is lowered. The connecting portion of the fixing metal fitting 102 protrudes from the tip of 103a. By connecting the attachment member to this connection portion, the solar cell module can be installed on the roof.

  By the way, depending on the shape of the roof tile and the fixing method, the roof tile 103a may not be pulled out. For example, as a countermeasure against typhoons, there is a house where tiles themselves are nailed against a roof using nails or the like. In such a case, the tile material 103a must be broken, resulting in problems such as an increase in waste and the need for a replacement tile material. In addition, when the tile material laid on the roof to which the solar cell module is attached is abandoned, a replacement tile material cannot be procured, so a method of breaking the tile material may be adopted. Can not. Therefore, a roof fixing device having a structure in which a hole is formed in the tile material using a drill or the like, and a column having a support portion for the mounting member is fixed to the base material through the hole ( Patent Document 1).
