Description

Technical Field

[0001] This invention relates to a solar panel installation structure and its construction method, and more specifically, to a technique for installing the installation structure on the roof in a non-drilling manner as a technology for solving the problem of roof leakage in roof-type solar panel structures. Background Technology

[0002] Solar energy systems are widely used as a sustainable energy solution, and to maximize space utilization, they are mostly installed on building rooftops. When installing solar panels on building roofs, the main method is to use anchor bolts or fixing bolts to secure the solar panels to the structure. However, this method damages the waterproof layer. Therefore, rainwater seepage or moisture accumulation can lead to leakage problems.

[0003] To address roof leaks that occur when installing solar panels, new buildings typically have their anchor bolts and reinforcing bars welded together before the concrete slab is finished. Existing buildings are waterproofed by drilling holes, injecting a chemical solution, inserting the anchor bolts, and allowing it to cure. However, for older buildings, the exact location of the waterproofing layer is difficult to determine, and architectural plans are often lost, making it easy for drilling to cause leaks.

[0008] Patent Document 3: KR ​​10-2022-0001991A, 2012.01.05. Summary of the Invention

[0009] The problem the invention aims to solve

[0010] To address this type of roof leakage problem, various waterproofing technologies have been developed. These include waterproofing gaskets and silicone sealant methods, anchor bolt waterproofing methods, and non-drilling installation methods. Among these, the non-drilling installation method does not involve directly drilling holes in the roof; instead, it uses the weight of concrete blocks or a heavy hammer to secure the structure.

[0011] However, non-drilling methods, which use heavy concrete blocks or weighted hammers for fixing, place a significant load on the building structure when installed on the roof. This poses a particular risk of structural problems, especially for older buildings or those designed with insufficient load-bearing capacity. Furthermore, even with uniformly distributed concrete blocks, the load may not be evenly distributed, leading to concentrated pressure in specific areas and potentially damaging the roof structure or waterproofing.

[0012] Therefore, the problem (objective) to be solved by the present invention is to provide a roof railing fixed solar panel installation structure and its construction method, which can safely install solar panels while preventing roof leakage. On the one hand, even when installed, it will not cause structural problems to old buildings or buildings with insufficient load-bearing capacity at the time of installation. On the other hand, by integrating with the roof railing, the fixing force is strengthened, thereby being able to withstand wind pressure.

[0013] Furthermore, the present invention is not limited to the aforementioned problems; in addition, various other problems can be further solved by means of the embodiments described below and the techniques described in the claims.

[0014] Solution for solving the problem

[0015] The present invention, in an embodiment for achieving the above objectives, provides a roof railing-fixed solar panel installation structure for installing a solar panel structure on a roof, comprising: a pair of track fixing plates, respectively fastened to the inner walls of opposite roof railings; a plate fixing track, both ends connected to the pair of track fixing plates and disposed in a close fit on the exposed roof bottom surface between the pair of track fixing plates; and a concrete block embedded inside the plate fixing track, with multiple reinforcing bars inside, the lower part of the solar panel structure's support fixed to its upper part.

[0016] Additionally, the pair of track fixing plates may each include: a railing fixing plate, fastened to the inner wall of the roof railing by bolts; and a pair of track fixing plates, extending from the railing fixing plate and inserted into the plate to fix the track.

[0017] Additionally, holes may be formed in the railing fixing plates so that the reinforcing bars pass between the pair of track fixing plates and are fixed to the roof railing.

[0018] In addition, the plate fixing track can be a U-shaped structure with an open top, with its upper ends facing each other and arranged side by side, and the upper ends are bent towards the center, so that the width of the entrance of the plate fixing track is smaller than the width inside.

[0019] Additionally, a protective layer made of rubber sheet or mortar cement layer can be formed between the track fixing plate and the inner wall of the roof railing.

[0020] In addition, the plurality of the roof railing fixed solar panel installation structures can be configured to be orthogonal to each other along a first direction and a second direction. The intersection of the orthogonal roof railing fixed solar panel installation structures configured along the second direction is formed with a groove so that the roof railing fixed solar panel installation structures configured along the first direction can pass through without interference. The solar panel structures are only installed on the roof railing fixed solar panel installation structures configured along the first direction.

[0021] In addition, it also includes a pipe-shaped groove embedded inside the concrete block. In the pipe-shaped groove, the inlet for injecting water is exposed on the upper side of one side of the concrete block, and the outlet is exposed on the lower side of the other side of the concrete block. The pipe-shaped groove has a structure that gradually slopes downward from the inlet to the outlet. The outlet of the pipe-shaped groove is connected in the horizontal direction to the outlet formed on the side of the plate fixing track.

[0022] In addition, another embodiment of the present invention for achieving the above-mentioned objective provides a construction method for a roof railing fixed solar panel installation structure, which includes the following steps: fastening track fixing plates to the inner walls of roof railings facing each other; setting a plate fixing track such that both ends of the plate fixing track are connected to a pair of track fixing plates and are in close contact with the exposed roof bottom surface between the pair of track fixing plates; inserting multiple steel bars into the interior of the plate fixing track; and pouring concrete into the interior of the plate fixing track and curing it to form a concrete block; in the step of setting the plate fixing track, applying primer to the position where the plate fixing track is placed, applying mortar cement on the primer, placing the plate fixing track, and allowing it to cure.

[0023] Invention Effects

[0024] As described above, the following effects can be obtained according to the embodiments of the present invention.

[0025] First, by not drilling holes in the roof floor, the risk of leaks caused by damage to the waterproof layer can be eliminated at the source, and it can also be effectively applied to old buildings.

[0026] Secondly, by using reinforced concrete to integrate the roof railings and the solar panel structure, the stability of the structure is greatly enhanced. This reduces the impact of the external environment and prevents the solar panel structure from being blown off the roof by wind pressure.

[0027] Third, by forming the track fixing plate as This shape further stabilizes the plate-fixing track to the track fixing plate, thereby enhancing the stability of the structure.

[0028] Fourth, since no holes are drilled in the roof, it can be easily applied to existing buildings and can also be safely constructed on old buildings without design drawings.

[0029] Fifth, since no holes are drilled into the roof surface, there is no need for the additional materials required for drilling and waterproofing, which is necessary for drilling construction methods, thus reducing construction costs. Attached Figure Description

[0048] Hereinafter, with reference to the accompanying drawings and detailed embodiments, the advantages and features of the present invention, as well as methods for achieving these advantages and features, will be clearly understood. In this specification, the same reference numerals denote the same constituent elements. Furthermore, when referred to as "A and / or B," it may indicate both A and B, or possibly one of A or B. Additionally, the dimensions and shapes of the constituent elements shown in the various drawings may be exaggerated, but this is merely for illustrative purposes and not intended to be limiting.

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0050] Figure 1 This is a schematic diagram illustrating a solar panel installation structure according to an embodiment of the present invention, showing the state in which the solar panel structure is installed.

[0051] Reference Figure 1 In one embodiment of the present invention, the solar panel mounting structure 10 is a support structure for mounting the solar panel structure 1 on the roof 2 in a non-drilling manner. The structure is mounted on the roof 2 using the roof railing 2b, rather than directly drilling holes in the bottom surface 2a of the roof.

[0052] The solar panel structure 1 may include a solar panel and a bracket (post) for fixing the solar panel to the solar panel mounting structure 10. There may be one or more brackets, the lower end of which is fastened to the solar panel mounting structure 10.

[0053] Adjacent structures of solar panel structure 1 can be arranged to face different directions alternately. For example, such as Figure 1 As shown, the solar panels of solar panel structure 1 are alternately oriented towards the east and west sides to realize an east-west solar power generation system.

[0054] Figure 2 It is shown schematically. Figure 1 The diagram shown is an exploded perspective view of the solar panel installation structure. Figure 3 It is shown in magnification Figure 2The diagram shows a cross-sectional view of the connection between the solar panel installation structure and the roof railing. Figure 4 Viewed from the direction of arrow A Figure 3 The diagram shows the assembled state of the solar panel installation structure.

[0055] Reference Figures 1 to 4 According to one embodiment of the present invention, the solar panel mounting structure 10 includes a pair of track fixing plates 11 fixed to the inner wall of the roof railing 2b.

[0056] A pair of track fixing plates 11 are connected to the bottom surface 2a of the roof. The upper part of the pair of track fixing plates 11 is open and can be generally shaped like a roof. shape.

[0057] Each pair of track fixing plates 11 includes: a railing fixing plate 11a, fixed to the inner wall of the roof railing 2b; and a pair of track fixing plates 11b, arranged side by side on the railing fixing plate 11a in a direction away from the inner wall of the roof railing 2b, for inserting plates to fix the track 12.

[0058] The railing fixing plate 11a is fastened to the inner wall of the roof railing 2b by bolts b. The railing fixing plate 11a has a fastening hole h1 for the bolts b to pass through, and a hole h2 in the center for the ends of multiple steel bars 13 inside the plate fixing track 12 to pass through.

[0059] A pair of track fixing plates 11b are formed side by side in the direction away from the inner wall of the roof railing 2b from the railing fixing plate 11a. The pair of track fixing plates 11b are spaced apart, and when viewed from above, they have an open structure at the top and bottom. As a result, the bottom surface 2a of the roof 2 is exposed between the pair of track fixing plates. Moreover, the end of the fixing plate 12 is fixed by a fixing plate inserted between the track fixing plates 11b. The fixing plate 12 is supported in the width direction by the pair of track fixing plates 11b in the state of being inserted between the pair of track fixing plates 11b.

[0060] The brackets of the solar panel structure 1 are securely fastened to the panel fixing track 12. The panel fixing track 12 is a straight structure, positioned across the roof bottom surface 2a of the roof 2. Its cross-section is approximately U-shaped, and its interior is filled with concrete blocks 14 that have been poured and cured. Furthermore, the upper ends 12a, which are parallel to each other and facing each other, are bent horizontally inwards. Therefore, since the entrance 12b of the panel fixing track 12 is smaller than the inner side, the concrete blocks 14 poured into and cured inside the panel fixing track 12 will not detach from the panel fixing track 12 and can be stably fixed.

[0061] The concrete block 14 is formed by pouring concrete into the interior of the slab fixing track 12 and then allowing it to cure. The concrete block 14 has multiple reinforcing bars 13 inside. (Example...) Figure 3As shown, the two ends of the reinforcing bar 13 are fixed to the inner wall of the roof railing 2b through holes h2 formed in the center of the railing fixing plate 11a in the track fixing plate part 11. Thus, the concrete block 14 can be stably bonded and fixed to the roof railing 2b by the reinforcing bar 13.

[0062] like Figure 3 As shown, a protective layer 3 can be further formed on the inner wall of the roof railing 2b. The protective layer 3 can be made of a rubber sheet or a mortar cement layer.

[0063] The protective layer 3 seals the area around the holes created during the tightening of the bolts b and the reinforcing bars 13, thereby preventing rainwater from entering the interior of the roof railing 2b. In addition, it buffers the impact (vibration or shaking) transmitted to the track fixing plate 11 and disperses the pressure, thereby preventing the fixing force of the track fixing plate 11 to the roof railing 2b from loosening.

[0064] Figure 5 This diagram schematically illustrates the construction process of a solar panel installation structure according to an embodiment of the present invention.

[0065] Reference Figure 5 The track fixing plate 11 is secured to the inner wall of the roof railing 2b using bolts b. Before locking the track fixing plate 11 to the inner wall of the roof railing 2b, a protective layer 3 is formed on the inner wall of the roof railing 2b, upon which the track fixing plate 11 can be fixed. At this time, the bolts b penetrate the protective layer 3 and are fixed to the roof railing 2b, thereby preventing the fixing force of the track fixing plate 11 from weakening.

[0066] Next, the plate fixing track 12 is inserted between a pair of railing fixing plates 11a of the track fixing plate part 11, and the plate fixing track 12 is placed on the roof bottom surface 2a of the roof 2. Before placing the plate fixing track 12 on the roof bottom surface 2a of the roof 2, the roof bottom surface 2a used for placing the plate fixing track 12 is cleaned, a primer is applied, and then mortar cement is applied on it. Then, the plate fixing track 12 is placed on the mortar cement and allowed to cure. During this process, the plate fixing track 12 becomes integrated with the roof bottom surface 2a of the roof 2 through the mortar cement, thereby improving the fixing force.

[0067] Next, multiple reinforcing bars 13 are arranged inside the plate fixing track 12. The reinforcing bars 13 are inserted and fixed to the roof railing 2b through holes h2 formed in the railing fixing plate 11a. Before the reinforcing bars 13 are arranged, the railing fixing plate 11a is locked to the roof railing 2b, and additional holes for inserting the reinforcing bars 13 into the roof railing 2b can be formed by using a drilling bit or the like.

[0068] Next, concrete is poured into the interior of the plate fixing track 12 and allowed to cure, forming a concrete block 13 that serves as the weight. Then, the bracket of the solar panel structure 1 can be fastened to the upper part of the concrete block 13 by bolt locking.

[0069] Figure 6 This is a schematic diagram illustrating the configuration structure of a solar panel mounting structure according to an embodiment of the present invention.

[0070] like Figure 1 As shown, in one embodiment of the present invention, multiple solar panel mounting structures 10 can be arranged side by side in a row along one direction on the bottom surface 2a of the roof, but this is only one example. Figure 6 As shown, multiple interconnected structures can also be set up like a Go board.

[0071] Solar panel structures 1 are installed only on multiple solar panel installation structures 10 arranged side-by-side in one direction (first direction), while solar panel installation structures 10' arranged in another direction (second direction, orthogonal to the solar panel installation structures 10) do not have solar panel structures 1 installed. That is, the solar panel installation structures 10' without solar panel structures 1 are reinforced to fix to the roof 2 to prevent the solar panel installation structures 10 with solar panel structures 1 from being lifted by wind pressure.

[0072] The solar panel mounting structure 10' and the solar panel mounting structure 10 are constructed with the same structure. A groove is formed at the intersection of the solar panel mounting structures 10 and 10', such as... Figure 6 As shown in the circled portion, the solar panel mounting structure 10 passes through the groove, thereby enabling an interference-free configuration.

[0073] Figure 7 This is a schematic cross-sectional view of a concrete block according to another embodiment of the present invention, (a) showing the state without the groove plug, and (b) showing the state with the groove plug assembled.

[0074] Reference Figure 7 In another embodiment of the present invention, a water-storage pipe trough 25 is embedded in the concrete block 24. By filling the inside of the pipe trough 25 with water, the weight of the solar panel mounting structure 10 is increased. Older buildings or buildings with insufficient load-bearing capacity in their design may experience structural problems when subjected to long-term heavy loads. Therefore, by increasing the load on the solar panel mounting structure 10 only in windy weather, and emptying the pipe trough 25 in weather when heavy loads are not required (weak wind weather), it is possible to prevent the building from bearing excessive loads for extended periods.

[0075] An inlet 25a is formed at one end of the pipe-shaped groove 25, protruding to the upper part of one side of the concrete block 24, and an outlet 25b is formed at the other end, protruding to the lower part or side of the other side of the concrete block 24. Preferably, the outlet 25b may be formed on the lower side of the other side of the concrete block 24. Moreover, corresponding to the outlet 25b formed in the pipe-shaped groove 25, an outlet (not shown) is provided on the plate fixing track 12 for discharging water discharged through the outlet 25b of the pipe-shaped groove 25 to the outside of the plate fixing track 12.

[0076] The pipe-shaped channel 25 can be made of metal pipe, and concrete can be poured into it while it is set inside the plate fixing track 12, thereby forming inside the concrete block 24. The pipe-shaped channel 25 is set so as not to interfere with the reinforcing steel 13.

[0077] Plugs 251 and 252 are provided at the inlet 25a and outlet 25b of the pipe-shaped groove 25. The outlet 25b of the pipe-shaped groove 25 can be configured to communicate with the outlet of the plate fixing rail 12 on a horizontal line. Thus, while the plug 252 is sealed through the outlet of the plate fixing rail 12, it can also seal the outlet 25b of the pipe-shaped groove 25.

[0078] The pipe-type trough 25 may have a structure that gradually slopes downward from the inlet 25a to the outlet 25b. Thus, water injected through the inlet 25a and stored inside flows naturally to the outlet 25b by gravity. When the plug 252 used to seal the outlet 25b is removed, the pipe-type trough 25 is discharged through the outlet 25b, and the water discharged through the outlet 25b is discharged to the outside of the plate fixing track 12 through the outlet of the plate fixing track 12.

[0079] As shown above, specific terminology has been used to describe and illustrate preferred embodiments of the present invention, but these terms are only for explicit description of the invention. Clearly, various modifications and alterations can be made to the embodiments of the invention and the terminology used without departing from the spirit and scope of the appended claims. Such modified embodiments should not be considered as departing from the spirit and scope of the invention, but rather as falling within the scope of the appended claims.
