Description

  The present invention relates to a solar power module mount for installing a solar power module.

  As a means for installing the solar power generation module, there is a means for installing it on a frame in which a steel frame is assembled. Since the solar power generation module fixed to the steel frame frame is greatly affected by the wind, it is necessary to firmly fix the steel frame frame. Therefore, means for driving and fixing the anchor bolt at the installation position of the gantry is employed. However, when the installation position is on the rooftop, the anchor bolts are driven to cause a crack in the waterproof layer on the rooftop, resulting in inconvenience that rain leakage occurs.

  Moreover, the fixing means which uses a heavy stone instead of an anchor bolt is employ | adopted. As this weight, for example, a frame is fixed by a concrete block or the like. When such a weight is used, it is possible to fix the anchor bolt without driving it.

  The pedestal described in Patent Document 1 has a base portion formed by projecting a bolt on the upper surface of a rectangular base, and a steel frame is connected to the base portion. According to this stand, in particular, the number of parts is reduced to reduce the cost. For this reason, the structure of the frame is combined in a right triangle shape, and a reinforcing member is attached to the connecting portion between the frame and the base portion to increase the overall strength.

  On the other hand, the gantry described in Patent Documents 2 and 3 integrates the power generation module and the gantry and uses the gantry itself as a weight. This gantry uses a gantry in which a solar power generation module has been assembled in advance, and in the installation work, the solar power generation module is transported and installed together with the gantry.

  According to the conventional steel frame mount, the use of anchor bolts has the disadvantage of causing cracks in the waterproof layer on the roof. In addition, when a heavy stone such as a block is used on the roof, the load on the roof becomes very heavy, and there is a possibility that the existing building or the like where the photovoltaic power generation module is not planned to be installed in advance has insufficient durability.

  On the other hand, in the pedestal described in Patent Document 1, a base portion formed by projecting a bolt on a rectangular base is used, but sufficient fixing force is obtained only by placing the base portion on the installation surface. Cannot be obtained. Therefore, also in Patent Document 1, an anchor bolt is required to fix the gantry. In addition, a reinforcing member is attached to the connecting part between the foundation and the frame to increase the strength and reduce the total number of parts, but many bolts are used to connect the frame and the foundation. And many bolts and nuts are used when assembling the frame into a right triangle. For this reason, a large number of bolts and nuts need to be tightened for the installation work of the gantry, resulting in inconvenience that a lot of labor is required.

  Furthermore, as described in Patent Documents 2 and 3, when the power generation module and the gantry are integrated and the gantry instead of the weight is installed on the roof, there is no frame assembly work on the roof, but the load on the roof becomes very heavy. Therefore, a problem arises in durability. Moreover, since the installation work is performed in a state in which the photovoltaic power generation module is assembled in advance, heavy equipment is indispensable for this installation work. Therefore, there is an inconvenience that the work cost becomes very large due to the large-scale transportation such as transporting heavy machinery and securing the crane movement range for the solar power generation module installation work. In addition, the number of high-rise buildings is increasing year by year, and it is becoming increasingly difficult to carry the work using heavy machinery onto the roof of the high-rise building.

  Therefore, the present invention has been created to solve the above-described problems, and the frame for the photovoltaic power generation module that can be easily attached to the power generation module while the assembly work of the frame for constructing the frame is extremely simple. It is intended to provide.
