  However, in the conventional construction method for injecting the caulking agent, the trouble of injecting the caulking agent is generated. In particular, when installing solar energy utilization devices so as to cover a wide area of the entire roof, the number of solar energy utilization devices to be installed is increased, and each unit is securely connected and fixed to the roof side. It is necessary to use a number of installation fixtures. In addition, each installation fixture also needs to be screw-fixed at a plurality of locations, so the number of injections of the caulking agent is assumed to be several hundreds or more. And from this, it is considered that a coherent work time has occurred due to the injection work of the caulking agent, and this work time affects the total construction time of the solar energy utilization device.

  However, in those skilled in the art of roof construction and repair, since the installation of solar energy utilization devices has become widespread, it has become customary to take measures against water leakage by using a caulking agent in relation to the roof. In particular, even in the installation of solar cell panels where demand and spread are rapidly expanding, it is considered that there was no particular question about the point that the operation of injecting the caulking agent was required.

  However, as described above, the time for the operation of injecting the caulking agent affects the total construction time of the solar energy utilization device. For this reason, the inventors of the present application pay attention to the time for injecting the caulking agent, and in order to shorten the total construction time, the caulking agent is being injected, but the coking agent is intentionally used. A new technology that can take measures against water leakage without injecting agent was investigated.

  Moreover, in the structure disclosed by patent document 1, it is set as the form by which a waterproof sheet (waterproof cover) is laid by the front surface side of a roof material, That is, between a roof material and a field board, ie, a roof material. In the configuration where the waterproof sheet is laid on the front side of the base plate on the back side, a hole is formed in the waterproof sheet by a screw breaking through the waterproof sheet. Need to be sealed.

  In particular, in the case of a form in which a waterproof sheet is laid on the front side of the field board on the roof of an existing house, there is no need to lay a waterproof sheet on the roof material as in Patent Document 1, and the existing waterproof There is an advantage that the sheet can be used as it is. For this reason, about the form by which a waterproof sheet is laid on the front surface side of such a field board, the technique which can perform a water leak countermeasure without performing the injection | pouring operation | work of a caulking agent is anticipated.

  On the other hand, in patent document 1, since it is a form which provides a waterproof sheet in the front surface side of a roof material, even if such a subject cannot be considered even if patent document 1 is referred, inventors, Considering the actual form of the roof of the existing house, it has been studied repeatedly.
