Solar power generation devices use multiple solar modules to directly convert sunlight into electrical energy. They are free of air pollution, noise, heat, and vibration, are easy to maintain, and have a long lifespan, making them a new source of energy. is in the spotlight.

Since these solar power generation devices are capable of small-scale power generation, even individuals other than the government or local government are installing them to generate power. In particular, the roofs of prefabricated buildings such as factory buildings are usually large, so solar power generation devices cannot be installed. It is becoming the best place to be.

Because the roof of a prefabricated building must be installed lightweight, it is often installed as a sandwich panel with urethane or Styrofoam embedded in it.

An example of a solar power generation device installed on the roof of a building is disclosed in Republic of Korea Patent Registration No. 10-2098026 (registered on April 1, 2020, hereinafter referred to as 'Patent Document 1').

A plurality of module support pillars are installed on the upper part of the sandwich panel roof, and square pipe members are installed in the panel valley along the longitudinal direction of the panel valley to support these module support pillars.

In addition, the square pipe members are installed and fixed by long bolts that are directly driven into the sandwich panel roof and extend vertically upward.

However, according to the roof installation structure of solar modules according to the prior art, when the sandwich panel roof is repeatedly rocked from side to side along with the square pipe members or deformed due to strong drafts, etc., the sandwich panel roof is centered around the area where the long bolt penetrated. No matter how much silicone waterproofing is done, there is a problem that water leakage damage may occur during rain or snow, or the water damage may become more severe over time.

In addition, while working in the process of constructing a square pipe member along the panel rib, the square pipe member cannot be installed in the middle of the panel rib, but is easily tilted to either the left or right side within the panel rib, and is simply fixed and installed by a long bolt. Therefore, there is a problem in that the spacing between square pipe members, which must be installed to maintain a constant distance (approximately 3,000 mm) at the top of the sandwich panel roof, becomes unstable, which may weaken the structural strength supporting the solar module. .

Meanwhile, according to the roof installation structure of solar modules according to the prior art, when installing solar modules on a sandwich panel roof, a plurality of module support pillars installed vertically on the upper part of each pipe member are installed on both left and right sides to support the solar modules. Since it must be supported by a plate-shaped bracket member joined from the side, there is a problem that the construction cost may increase due to the use of the bracket member, the construction period may increase, and work may become inconvenient.

In addition, as shown in Figures 3 and 4, horizontal through holes 110 are provided on both left and right sides of the basic square pipe member 100 at regular intervals corresponding to the portion surrounded by the basic square pipe installation adjustment bracket 300. This perforation is formed, and the horizontal fastening bolt 120 is horizontally inserted and coupled to the horizontal through hole 110 so as to penetrate the basic square pipe member 100 from side to side, and is inserted into either side of the left and right horizontal through holes 110 to the other side. It is preferable that the horizontal fastening nut 130 is inserted and fastened to the end opposite to the head of the horizontal fastening bolt 120 exposed to the side.

Accordingly, it is possible to easily fix and couple the foundation square pipe installation adjustment bracket 300 to the foundation square pipe member 100, and when only the foundation square pipe installation adjustment bracket 300 is fixed to the sandwich panel roof 10, the foundation The square pipe member 100 can also be easily installed on the upper part of the sandwich panel roof 10, and as shown in FIG. 8, the basic square pipe member 100 is installed on the upper part of the sandwich panel roof 10. Even if water intrudes from the outside due to rainfall or snowfall, unlike the prior art, the basic square pipe member 100 is indirectly fixed to the sandwich panel roof 10 and the water infiltration path is fixed horizontally rather than vertically ( 100), it is possible to primarily prevent damage from water leakage by avoiding it primarily.

As shown in FIGS. 1 and 2, the module support column 200 is preferably provided as a square pipe having a ‘ㅁ’-shaped cross-sectional shape like the basic square pipe member 100.

Here, the module support column 200 is provided as a rectangular square pipe that is hollow in cross-section and whose horizontal side is in surface contact and coupled to the basic square pipe member 100 is longer than the vertical side, and the vertical short side is 0.28 to 0.34 times the horizontal long side.

At this time, if the length of the vertical short side of the module support pillar 200 is less than 0.28 times the length of the horizontal long side, the support strength of the solar module 20 by the module support pillar 200 may be slightly reduced, and if it exceeds 0.34 times. The weight saving effect of the face module support pillar 200 may be somewhat reduced.

As an embodiment of the present invention, as shown in Figures 1 and 2, it is preferable that the lower part of the module support column 200 is fixedly coupled to the basic square pipe member 100 by a pair of horizontal bolts 210. do.

Accordingly, the module support column 200 is connected to the foundation square pipe member 100 by a pair of horizontal bolts 210 that are horizontally fastened through the lower part of the module support column 200 and the foundation square pipe member 100. By being supported in an 'L' shape, the module support column 200 can be maintained more firmly coupled to the basic square pipe member 100.

Here, it is desirable that the distance between the pair of horizontal bolts 210 coupled through the long horizontal side of the module support column 200 be 0.29 to 0.47 times the width of the long horizontal side of the module support column 200.

Accordingly, the structural strength in which the module support column 200 is fixedly coupled to the foundation square pipe member 100 by the pair of horizontal bolts 210 can be further strengthened.

At this time, if the distance between the pair of horizontal bolts 210 is less than 0.29 times the horizontal width of the long side of the module support column 200, the support strength by the horizontal bolts 210 may be somewhat reduced, and if it exceeds 0.47 times. When fastening a pair of horizontal bolts 210 through each other, construction errors may easily occur due to work mistakes.

As shown in FIGS. 3 and 4, the basic square pipe installation adjustment bracket 300 has both ends coupled to the panel mount 11, and the middle portion is bent to surround the basic square pipe member 100. (100) is supported to be fixed at the top of the sandwich panel roof (10), but is positioned in a sliding manner at the top of the sandwich panel roof (10) so that the horizontal spacing between the plurality of basic square pipe members (100) can be adjusted. It is provided.

More specifically, as shown in FIG. 4, the foundation square pipe installation adjustment bracket 300 is provided in the form of a horizontal plate with both ends having a certain width, and slides in the horizontal direction in the longitudinal direction of the panel mountain 11 on the plate surface. The control hole 311 is bent to correspond to the upper shape of the basic square pipe member 100 between a pair of panel mount coupling parts 310 perforated in the form of a long hole and the pair of panel mount coupling parts 310. It is preferable to include a square pipe band 320 that is formed and surrounds the basic square pipe member 100 at the top.

Accordingly, as shown in FIGS. 3 and 8, the basic square pipe member 100 is easily supported by the basic square pipe installation adjustment bracket 300 due to the front cross-sectional shape of the basic square pipe installation adjustment bracket 300, forming a sandwich. It is possible to ensure that the fixed state within the upper surface of the panel rib 13 of the upper part of the panel roof 10 is firmly maintained, and even if the sandwich panel roof 10 is shaken by external strong winds, etc., the panel mountain 11 is maintained. The basic square pipe member 100 can be firmly fixed so that it does not easily rock left and right by the panel mountain coupling portion 310 that is coupled and fixed. As shown in Figures 5 and 6, the panel mountain coupling portion ( A sliding adjustment hole 311 is formed in 310 so that the gap between the basic square pipe members 100 supporting the module support column 200 is such that the basic square pipe members 100 move in one direction from the panel bone 13 during construction. Even if it becomes biased and uneven, the position of the basic square pipe member 100 can be easily adjusted and fixed again.

Figure 5 is a diagram showing an example in which the basic square pipe member 100 according to the present invention is biased to the left during construction in the panel frame 13, and Figure 6 shows the basic square pipe member 100 of Figure 5 being installed. This is a diagram illustrating a construction state in which the adjustment bracket 300 is moved back to the middle position of the panel bone 13 by adjusting the sliding position, so that the spacing between the basic square pipe members 100 is constant.

As an embodiment of the present invention, the basic square pipe installation adjustment bracket 300 is preferably made of galvanized steel sheet with a thickness of about 4 mm.

Meanwhile, as shown in FIG. 4, band through-holes 321 are perforated on both left and right sides of the square pipe band 320 to correspond to the horizontal through-hole 110, and the horizontal fastening bolt 120 is inserted into the band through-hole ( 321) and the horizontal through hole 110, it is preferably inserted through the basic square pipe installation adjustment bracket 300 and the basic square pipe member 100 together.

In addition, as shown in Figures 4 and 7, the basic square pipe installation adjustment bracket 300 according to the present invention is interposed between the panel mountain coupling portion 310 and the panel mountain 11 to form a basic square pipe installation adjustment bracket ( When the bracket fixing assembly 400 is fastened to the panel mount 11 through the sliding adjustment hole 311 so that the panel mount coupling portion 310 of 300 is fixed to the panel mount 11, the water penetration path is avoided once again. It is desirable to further include a panel acid cover pad 330 to achieve a waterproof function as much as possible.

Accordingly, the process of coupling the basic square pipe installation adjustment bracket 300 to the upper part of the sandwich panel roof 10 by the panel mountain cover pad 330 is made easier with a more buffering function, and at the same time, Even if the sandwich panel roof 10 is shaken due to an earthquake, etc., the direct transmission of vibration to the panel mountain joint 310 can be alleviated to prevent direct damage to the foundation square pipe installation adjustment bracket 300, and rainfall. Even if water intrudes from the outside due to snowfall, etc., the water infiltration path through the sliding adjustment hole 311 and the bracket fixing assembly 400 is once again avoided by the panel cover pad 330, effectively achieving the waterproof function. It can be done as much as possible.

As an embodiment of the present invention, the panel mountain cover pad 330, as shown in FIG. 7, is formed by bending the plate-shaped member to have an approximately trapezoidal shape corresponding to the shape of the panel mountain 11 on the top cross section. It is provided and preferably contains aluminum metal material so that it can exhibit some degree of elasticity.

In addition, as shown in FIG. 7, the panel mountain cover pad 330 has a through hole formed in the center through which the T-shaped rotating bolt 410, which will be described later, of the bracket fixing assembly 400 is inserted, and the T-shaped rotating bolt A water leak avoidance rib 331 is formed to protrude upward and has a certain thickness and surrounds the through-hole through which (410) is inserted, and is bonded to the lower surface of the panel cover pad 330 to form a panel cover pad 330 and a panel. It includes a waterproof adhesive tape 333 interposed between the acids 11.

Accordingly, even if water intrudes from the outside due to rainfall or snowfall, the water infiltration path through the sliding adjustment hole 311 and the bracket fixing assembly 400 is maintained along the outer circumference of the water leak avoidance rib 331 by the water leak avoidance rib 331. By avoiding the water around the perimeter, the waterproofing function that prevents water damage from occurring by secondary avoidance of water leaks by the water leak avoidance rib 331 can be further strengthened, and even before the bracket fixing assembly 400 is fastened. The panel mount cover pad 330 is firmly adhesively fixed to the top of the panel mount 11 by the waterproof adhesive tape 333, and at the same time, the T-shaped rotating bolt 410 penetrates the upper surface of the panel mount 11. Waterproofing of the through fastening hole area can be made more effective.

As an embodiment of the present invention, it is preferable that the height at which the water leak avoidance rib 331 protrudes upward from the upper surface at the center of the panel cover pad 330 is approximately 0.75 to 1.0 times the thickness of the basic square pipe installation adjustment bracket 300. do.

Accordingly, even if water infiltrates from the outside through the sliding adjustment hole 311 due to rain or snow, the infiltration path of the water is avoided to the outside of the water leak avoidance rib 331, so that the T-shaped rotating bolt 410 is installed on the panel. Water leakage can be effectively prevented by blocking water from directly penetrating vertically through the through fastening hole passing through (11).

More specifically, the height at which the water leak avoidance rib 331 protrudes upward from the upper surface of the panel mount cover pad 330 may be provided to be 3 mm.

Here, if the height at which the water leak avoidance rib 331 protrudes upward is less than 0.75 times that of the basic square pipe installation adjustment bracket 300, the space between the flat washer 430, which will be described later, of the bracket fixing assembly 400 and the water leak avoidance rib 331. As the separation distance increases, water infiltration may occur to some extent, and if it exceeds 1.0 times, the flat washer 430 may not contact the upper surface of the panel mount coupling portion 310 and may be lifted, resulting in more water infiltration. there is.

In addition, it is preferable that the thickness between the outer diameter and inner diameter of the water leak-avoiding rib 331 is approximately 1/14 to 1/4 times the hem width length of the sliding adjustment hole 311.

Accordingly, even if water infiltrates from the outside through the sliding adjustment hole 311 due to rainfall or snowfall, the water infiltration path is dispersed and avoided around the outer circumference of the water leak-avoiding rib 331, thereby preventing the T-type rotating bolt 410. Water leakage can be prevented more effectively by blocking water from directly penetrating vertically through a through fastening hole penetrating the panel mount 11.

Here, if the thickness between the outer diameter and the inner diameter of the water leak avoidance rib 331 is less than 1/14 times the hem width length of the sliding adjustment hole 311, the effect of dispersing the water penetration path around the outer circumference of the water leak avoidance rib 331 is It may become insignificant, and if it exceeds 1/4 times, the thickness may become so thick that sliding adjustment of the basic square pipe installation adjustment bracket 300 and the basic square pipe member 100 through the sliding adjustment hole 311 may not be achieved smoothly. there is.

Meanwhile, the T-shaped rotating bolt 410 has an end extending toward the opposite side of the rotating head 411, which will be described later, penetrating the center of the waterproof adhesive tape 333 and upward through the through hole of the panel mount cover pad 330. It is fastened to be exposed, and the waterproof adhesive tape 333 preferably includes a butyl tape that has both waterproofing and adhesive properties.

Here, the hem width of the sliding adjustment hole 311 of the panel mountain coupling portion 310 is formed to correspond to the outer diameter of the water leak-avoiding rib 331, so that the corner pipe installation adjustment bracket 300 can be adjusted through the sliding adjustment hole 311. During sliding movement, it is desirable that the water leak avoidance rib 331 moves relative to the sliding adjustment hole 311 to achieve solid sliding control and water leak avoidance.

As shown in FIGS. 3 and 4, the bracket fixing assembly 400 is coupled to the panel mount 11 of the sandwich panel roof 10 through both ends of the basic square pipe installation adjustment bracket 300 to adjust the basic square pipe installation. It is provided to ensure that the adjusted position of the bracket 300 and the basic square pipe member 100 is fixed and to form a waterproof structure.

Accordingly, the square pipe member supporting the module support column 200 extends directly vertically upward with respect to the square pipe member so that it is fixed in a lying state on the panel bone 13 along the panel bone 13 of the sandwich panel roof 10. By avoiding installation by long bolts that become deeply embedded, it is possible to prevent water leakage damage from occurring and expanding during rain or snow through the long bolt installation portion due to repetitive shaking and deformation of the sandwich panel roof (10). Even if the spacing between the square pipe members supporting the module support column 200 becomes uneven due to the square pipe members being biased in one direction from the panel bone 13 during construction, the position of the square pipe members can be easily adjusted and fixed again. The square pipe members can be installed so that the spacing between the square pipe members is constant.

More specifically, as shown in FIG. 7, the bracket fixing assembly 400 is upward from the lower part of the panel mount 11 through both ends of the basic square pipe installation adjustment bracket 300, that is, the panel mount coupling portion 310.

A spring washer 440 inserted into the T-type rotating bolt 410 is coupled to the upper part of the T-shaped rotating bolt 410 to be provided on the upper part of the fixing nut 420, and a fixing nut 420 and a flat washer 430 And a waterproof cap 450 whose lower end extends to both ends of the basic square pipe installation adjustment bracket 300, that is, the upper surface of the pair of panel mount coupling portions 310, so as to cover both the spring washers 440. It is desirable.

Accordingly, the bracket fixing assembly 400 having a waterproof structure is coupled to the panel mount 11 of the sandwich panel roof 10 through both ends of the basic square pipe installation adjustment bracket 300, and is connected to the basic square pipe installation adjustment bracket 300 and At the same time, the adjusted position of the basic square pipe member 100 is fixed and the airtight waterproofing effect is further improved to prevent water leakage from occurring to the lower part of the sandwich panel roof 10 even if water intrudes from the outside due to rain or snowfall. It can be done as much as possible.
