The pillars constituting the pillar assembly parts 11, 13, 15, 17, and 19 (for convenience, only one example will be described) are provided with a filler accommodating space therein, and the upper surface thereof is shown on the inclined surface 11a (FIG. 4). ) The pillars 1 are preferably made of a synthetic resin material having excellent heat resistance and durability. The filling material filled in the pillars 1 may be made of a fluid such as water or oil, or sand.

In the embodiment of the present invention will be described in detail that the filler is made of a fluid such as water. And since the column assembly (11, 13, 15, 17) is all made of the same structure and arranged side by side will be described with only one example for convenience. The pillar assembly 11 is connected and fixed in a state in which the pillars 1, 3, and 5 overlap each other.

FIG. 2 is a cross-sectional view of the II-II of FIG. 1, and shows the state in which the pillars 1 and 3 are coupled to each other. The pillars 1 and 3 are fastened by the fastening member 31 in a state where a portion of one pillar 1 overlaps with a portion of another pillar 3. Fastening member 31 is preferably made of a conventional U bolt (U type bolt). That is, the upper part of the pillar 1 is wrapped with a u-bolt, and a part of the other pillar 3 is passed through the bracket 33 so that the bracket 33 and the u-bolt 31 are fastened with nuts 35. The pillar parts 1 and 3 can be continuously joined to each other.

However, the fastening member 31 can be applied to any structure that can only connect the columns (1, 3, 5) in succession to each other.

On the other hand, the column 1 is provided with an inlet 37 for injecting a filler made of fluid, and the inlet 37 is provided with a water level sensing device 39 as shown in FIG. 3. That is, the water level detecting device 39 is disposed in the column 1 to check whether a filler such as a fluid contained in the column 1 exists properly.

The water level detecting device 39 is a floating body guide 41 which penetrates and is coupled to the inlet 37, and a floating body 43 which is disposed inside the column 1 and guides and moves along the floating body guide 41. ). The floating body guide 41 serves to guide the floating body 43 to move a predetermined section in the up and down directions without the floating body 43 leaving the outside through the inlet 37.

Floating body 43 is to act as a float, so that the filling material consisting of a small amount of fluid in the column (1) will sink, and if the filling material is a lot of it can protrude above the inlet (37).

In addition, the outer circumferential surface of the floating body 43 is provided with a phosphor or a light emitting or luminous material layer, it is preferable that the identification is easy at night or far away. This floating body 43 is very useful for the operator to easily determine the state that the filler is filled in the interior of a plurality of pillars.

FIG. 4 is a diagram illustrating an embodiment of the present invention and shows pillars 1, 3, and 5. The pillars 1, 3, 5 are provided with inlets 37, 51, 53 for injecting filler. And the columns (1, 3) are provided with connectors 55, 57. And these connector (55, 57) may be fitted into the inlet (51, 53), respectively.

Therefore, the fillers receiving space of the pillars (1, 3, 5) are all connected, so when the filler such as fluid in the inlet 37 may be filled in the filler receiving space of the pillars (1, 3, 5).

In addition, the pillars 1, 3, and 5 may be equipped with exhaust holes 61, 63, and 65, and lids (not shown) for blocking the exhaust holes 61, 63, and 65, respectively.

Fixing nuts 67 for fixing the light collecting plate 21 are inserted into the inclined surfaces 11a of the pillars 1, 3, and 5 (shown in FIG. 5). The fixing nuts 67 are preferably formed by integrally molding the fixing nuts 67 when the pillars 1 are formed.

6 illustrates an example in which the light collecting plates 21 are coupled to the fixing nut 67. The light collecting plate 21 is placed on the column 1, and the light collecting plate 21 is fixed by the light collecting plate fixing bracket 69, and then fastened to the fixing nut 67 using the bolt 71. Will be fixed on. In the embodiment of the present invention, one pillar 1 has been described as an example, but the same structure may be applied to other pillars.

On the other hand, the pillar 1 is provided with a through hole 73 (shown in FIG. 5 and FIG. 7) that can be utilized for various purposes. The through hole 73 may be fixed by inserting an inverter fixing plate 75 (shown in FIG. 7). In addition, the inverter fixing plate 75 is coupled to an inverter (or a control device) required for the photovoltaic device. In this way, the through-hole 73 can be utilized for various purposes as well as fixing the inverter required for the photovoltaic device.

The lower portion of the pillar 1 is provided with a plurality of engaging grooves 91 in the inclined direction continuously. In addition, a horizontal adjusting member 95 provided with other locking grooves 93 corresponding to the locking grooves 91 in succession is disposed below the column 1.

This horizontal adjustment member 95, as shown in Figure 8, is very useful for leveling the column (1) in the case where the bottom surface on which the columns (1) are installed is uneven. That is, when the bottom surface on which the pillar 1 is installed is uneven, the horizontal adjustment member 95 may be disposed below the pillar 1 to adjust the horizontality of the pillar 1.

Referring to the process of installing the photovoltaic device of the present invention made in this way on the school roof, as follows.

First move the columns (1, 3, 5) to the installation site. And the pillars (1, 3, 5) are fixed with a fastening member 31, such as a U-bolt so that they are arranged in succession to each other. At this time, the worker couples the couplings 55 and 57 provided on the pillars 1 and 3 to the inlets 51 and 53 of the pillars 3 and 5, respectively.

As such, the pillar parts 11 connected to the pillars 1, 3, and 5 are arranged side by side with the other pillar part assemblies 13, 15, 17, and 19 arranged adjacently.

And when the filler made of a fluid such as water into the inlet 37 is filled with the filler receiving space provided in the interior of the column (1). At this time, the exhaust holes (61, 63, 65) in the open state in accordance with the degree of filling the filler is closed using the lid sequentially.

When the filler is made of sand, the sand may be first filled with the pillars 1, 3, 5, 7, ..., and then connected to each other to form the pillar assembly 11, 13, 15, 17, 19.

And the light collecting plate 21 is coupled to the inclined surface (upper surface) of the column assembly 11, 13, 15, 17, 19. At this time, as shown in FIG. 6, the light collecting plate 21 is fixed by the light collecting plate fixing bracket 69, and the light collecting plate fixing bracket 69 is fixed to the fixing nut 67 by the bolt 71.

And when the level of the column assembly (11, 13, 15, 17, 19) does not match, as shown in Figure 8 the horizontal adjustment member 95, for example, only a part of the column (1, 3, 5, for convenience) It will be inserted and inserted in the corner side of one side of the bottom surface. In this case, the horizontal adjusting member 95 may be in close contact with the locking groove 91 of the inclined locking groove 93 to maintain a firm fixed state.
