Description

[Technical Field]

[0001] The present invention relates to a fixing member for fixing a frame material that supports a solar panel to a roof material, as well as to a metal fitting that reinforcingly fixes the solar panel frame material to the roof material and an installation structure for the same. [Background technology]

[0002] Solar panels installed on roofs are supported by a lattice-shaped frame on the roof, with the solar panels fitted into the frame. Typically, fixing members are installed on the frame to secure the frame to the roof material.

[0003] As a fixing member, the roof fixing device described in Patent Document 1 is equipped with a plate-shaped base with a linear rail groove, a plate-shaped first pressing member for pressing and fixing the peripheral edge of the solar panel installed on this base, a plate-shaped second pressing member for electrically connecting the peripheral edge of the solar cell module, and bolts and nuts as fastening members for fixing the pressing members, and it is described that the solar panel can be installed on the roof easily, stably, and with good workability. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2004-251037 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even if the frame material is fixed only with the bolts and nuts that are the fastening members of the roof fixing device described in Patent Document 1, the solar panel can be blown around or subjected to impacts due to external factors such as wind or rain, causing the solar panel to vibrate.The vibrations are then transmitted to the frame material and roof fixing device, and repeated transmission of vibrations over many years can cause the bolts that are the fastening members of the roof fixing device to loosen.

[0006] It is difficult for individuals to climb onto the roof to check the installation status of solar panels or retighten the bolts, and even if a contractor is hired to retighten the bolts, there is a possibility that the bolts will loosen again over time, so regular inspections are necessary.

[0007] The present invention has been made in consideration of these circumstances, and aims to provide a reinforcing bracket for a solar panel frame material and its installation structure that prevents the fastening of the fixing member from loosening due to vibrations transmitted to the fixing member due to external factors, and that can be used in addition to existing fixing members to reinforcingly fix the frame material to the roof material later. [Means for solving the problem]

[0008] In order to solve the above problems, in addition to a fixing member for fixing a longitudinal rod-shaped frame material that supports a solar panel to a roofing material, the solar panel is characterized by having a metal fitting that further reinforces and fixes the frame material to the roofing material, which has a connecting portion that has a connecting hole for inserting a fastening member and connects to the roofing material, an attachment portion that holds the frame material from above and attaches it, a leaf spring portion that connects the attachment portion and the connecting portion without contacting the roofing material and the frame material and buffers vibrations that propagate from the attachment portion to the connecting portion, and a sheet-like buffer material on a first contact surface of the connecting portion on the roofing material side and a second contact surface of the attachment portion on the frame material side.

[0009] Preferably, the leaf spring portion is a mountain-shaped leaf spring having a first inclined plate rising from the connecting portion and a second inclined plate connected from the end of the first inclined plate to the mounting portion.

[0010] Preferably, the leaf spring portion is a parallel leaf spring having an approximately U-shape and two parallel plates parallel to the roof material and a connecting plate connecting the ends of the parallel plates.

[0011] Preferably, the present invention is characterized in that a fixing reinforcement bracket for a solar panel frame material as described in claim 2 and a fixing reinforcement bracket for a solar panel frame material as described in claim 3 are installed on one of the frame materials. [Effects of the Invention]

[0012] The fixing reinforcement fittings for solar panel frame materials of the present invention comprise a connecting portion that connects to the roof material, an attachment portion that holds the frame material from above and attaches it, and a leaf spring portion that connects the attachment portion and connecting portion without contacting the roof material or frame material and cushions vibrations transmitted from the attachment portion to the connecting portion, thereby making it possible to suppress vibrations transmitted from the frame material to the fixing member due to external factors.

[0013] According to the fixing reinforcement fittings for solar panel frame material of the present invention, the leaf spring portion has a mountain-shaped configuration and includes a first inclined plate rising from the connecting portion and a second inclined plate connecting from the end of the first inclined plate to the mounting portion, thereby effectively cushioning left-right vibrations of the frame material.

[0014] According to the fixing reinforcement fittings for the solar panel frame material of the present invention, the leaf spring portion is approximately U-shaped and has two parallel plates that are each parallel to the roof material and a connecting plate that connects the ends of the parallel plates, so that it can effectively cushion the vertical vibrations of the frame material.

[0015] According to the installation structure of the fixing reinforcement bracket for the solar panel frame material of the present invention, for one frame material, a fixing reinforcement bracket with a mountain-shaped leaf spring portion in the leaf spring section and a fixing reinforcement bracket with a parallel leaf spring portion in the leaf spring section are used, so that not only vibrations in the up-down and left-right directions but also vibrations in the diagonal direction can be damped, and vibrations in any direction can be damped.

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the roofing material R refers to the components that make up a roof, including not only roof surface components such as slates, but also roof underlayment such as sheathing boards and rafters.

[0018] First, we will explain how to install solar panels on a roof. When installing solar panels, as shown in Figure 3, a lattice-shaped frame material 20 made up of vertical frame members 21 and horizontal frame members 22 that support the solar panels is fixed to the roof using fixing members 10, and the solar panels (not shown) are then placed on the frame material 20.

[0019] As shown in Figures 2 and 3, the frame material 20 is a hollow, longitudinal rod-shaped rail having one convex portion 23, the other convex portion 24, and a concave groove 25 between them. The frame material 20 has horizontal frame members 22 extending laterally relative to the roof, and vertical frame members 21 extending vertically relative to the roof. Using the roof material R as a base, the vertical frame members 21 are mounted on the roof material R using fixing members 10, and using the vertical frame members 21 as a base, the horizontal frame members 22 are mounted on the vertical frame members 21, and using the horizontal frame members 22 as a base, the solar panels are mounted on the horizontal frame members 22.

[0020] As shown in Fig. 2, the fixing member 10 mainly comprises a base plate 11, a sliding fitting 12, and a press fitting 13. The base plate 11 is fixed to the roof material R by inserting screws B into the roof material R through connecting holes 11b provided in flanges 11a at both ends of the base plate 11. The sliding fitting 12 is inserted into the rail 11c of the base plate 11 parallel to the depth direction of the rail 11c, a vertical frame member 21 is placed on the sliding fitting 12, and the press fitting 13 is placed on the flange portion 21a of the vertical frame member 21, and is fixed with screws B so that the flange portion 21a and the sliding fitting 12 are connected from the top of the press fitting 13.

[0021] The fixing reinforcement fittings 100, 200 for the frame material 20 of a solar panel according to the present invention are fittings that can be added later in addition to the fixing member 10 for fixing the frame material 20 that supports the solar panel to the roof material R, and are used to reinforcingly fix the frame material 20 to the roof material R. The fixing reinforcement fittings 100, 200 are fittings in which a connecting portion 30 for fixing to the roof material R, a leaf spring portion 40 for cushioning vibrations, and an attachment portion 50 for attaching to the frame material 20 are continuously and integrally formed.

[0022] It is conceivable to add fixing members 10 later to increase the fixing strength between the frame material 20 and the roof material R, but once the frame material 20 is installed on the roof material R using fixing members 10, as shown in Figure 2, the fixing members 10 fix the frame material 20 to the roof material R so that they are sandwiched between the frame material 20 and the roof material R. Therefore, even if you try to add fixing members 10 later, you will have to forcefully lift the fixed frame material 20 and insert the fixing members 10 into the gap that is created. If you try to forcefully lift the frame material 20, a load will be placed on the other fixing members 10 that are already installed, which will ultimately reduce the fixing strength.

[0023] On the other hand, the fixing reinforcing brackets 100, 200 fix the frame material 20 by pressing it down from above, so that the frame material 20 can be fixed to the roof material R as a reinforcing addition without putting a strain on the existing fixing member 10.

[0024] [First embodiment] As shown in Figures 1 and 2, the fixing reinforcement bracket 100 of the first embodiment has a connecting portion 30, a mountain-shaped leaf spring portion 41 as a leaf spring portion 40, and an attachment portion 50, and further has a cushioning material 60 provided on the surface that contacts the roof material R and the frame material 20.

[0025] (Regarding the connecting portion 30) The connecting portion 30 is a plate for connecting and fixing the fixing reinforcement bracket 100 to the roof material R, and has two or more connecting holes 30a formed near the center of the connecting portion 30. Screws B, which are fastening members, are inserted through the connecting holes 30a into the roof material R to connect and fix the fixing reinforcement bracket 100 to the roof material R. One end of the connecting portion 30 is connected to the first inclined plate 41a of the mountain-shaped leaf spring portion 41.

[0026] (Regarding mountain-shaped leaf spring part 41) The leaf spring portion 40 of the fixed reinforcing bracket 100 according to the first embodiment is a mountain-shaped thin plate having a first inclined plate 41a rising at a predetermined angle from the connecting portion 30 and a second inclined plate 41b connecting the end of the first inclined plate 41a to the mounting portion 50. An inflection point 41c is formed at the joint between the first inclined plate 41a and the second inclined plate 41b.

[0027] At the inflection point 41c, the mountain-shaped leaf spring portion 41 is formed so that the first inclined plate 41a and the second inclined plate 41b maintain a constant angle θ. For example, if the angle θ is designed to be 45 degrees, when the angle θ opens to 45 degrees or more or tries to close to 45 degrees or less, an elastic force acts as a restoring force on the first inclined plate 41a and the second inclined plate 41b to maintain the angle at 45 degrees.

[0028] Since the fixed reinforcement bracket 100 is fixed to the roof material R at the connecting portion 30, the elastic force of the mountain-shaped leaf spring portion 41 to maintain a constant angle acts on the first inclined plate 41a and the second inclined plate 41b, and the elastic force acts in the opposite direction to the direction in which the vertical frame material 21 moves left and right, thereby cushioning the left and right vibrations transmitted from the vertical frame material 21.

[0029] The mountain-shaped leaf spring portion 41 buffers the vibrations transmitted from the vertical frame member 21, preventing the vibrations from being transmitted from the vertical frame member 21 to the fixing member 10 and the roof material R, and thus no load is applied to the screw B that fixes the substrate 11, preventing the screw B from loosening.

[0030] Furthermore, the mountain-shaped leaf spring portions 41 are not in contact with the roof material R or the vertical frame members 21. By making them not in contact, the vibration energy transmitted from the vertical frame members 21 does not act on the roof material R or the vertical frame members 21, but is converted into elastic energy by the roof material mountain-shaped leaf spring portions 41 and is confined within the system, cushioning the vibration and preventing it from being transmitted from the vertical frame members 21 to the fixing member 10 and the roof material R, thereby reducing the load on the screws B that secure the substrate 11.

[0031] The material of the mountain-shaped leaf spring portion 41 is preferably a highly water-resistant metal such as stainless steel. The material, length, thickness, etc. can be appropriately changed to obtain an optimal thickness depending on the amplitude and frequency of vibration of the frame material 20.

[0032] (Regarding the mounting portion 50) As shown in Figure 2, an attachment portion 50 is provided at the end of the second inclined plate 41b, and the attachment portion 50 is used to attach the fixing reinforcing bracket 100 to the vertical frame member 21. In this embodiment, the attachment portion 50 is substantially L-shaped and is attached so as to be hooked onto one of the protrusions 23 that form the recessed groove 25 of the vertical frame member 21. Even if attachment by hooking is not required, if structurally possible, locking holes may be provided in the attachment portion 50 and the vertical frame member 21, and the fixing reinforcing bracket 100 may be attached to the frame member 20 using fastening members such as screws and bolts.

[0033] Furthermore, the fixing reinforcing bracket 100 is fixed to the roof material R so that the mounting portion 50 biases the vertical frame member 21 in the direction of the roof material R. By fixing the fixing reinforcing bracket 100 so as to press down on the vertical frame member 21 from above, the vertical frame member 21 is prevented from vibrating in the up and down direction, no load is applied to the screws B, and the screws B that secure the board 11 do not loosen.

[0034] (About the cushioning material 60) 1 and 2, a first cushioning material 61 is provided on the first contact surface 31 of the connecting portion 30 on the roof material R side, and a second cushioning material 62 is provided on the second contact surface 51 of the mounting portion 50 on the frame material 20 side. The first cushioning material 61 and the second cushioning material 62 are preferably made of sheet-like rubber, and mainly cushion micro-vibrations with an amplitude smaller than the amplitude of vibrations that the leaf spring portion 40 cushions.

[0035] The order in which vibrations are transmitted is the first cushioning material 61 in contact with the vertical frame member 21, the mounting portion 50, the angle-shaped leaf spring portion 41, the connecting portion 30, and the second cushioning material 62. First, the first cushioning material 61 buffers small-amplitude vibrations transmitted from the vertical frame member 21, followed by the angle-shaped leaf spring portion 41 buffering large-amplitude vibrations, and then the second cushioning material buffers any vibrations that have not yet been fully buffered. Therefore, the first cushioning material 61, the angle-shaped leaf spring portion 41, and the second cushioning material 62 can buffer even complex vibrations that combine multiple vibrations of different amplitudes, preventing the transmission of small vibrations from the vertical frame member 21 to the roof material R and reducing the load on the screws B that secure the substrate 11.

[0036] The first cushioning material 61 is the part through which vibrations are first transmitted from the vertical frame member 21 to the fixed reinforcement bracket 100, and is therefore designed to be made of a material and have a thickness that provides strong cushioning properties.The second cushioning material 62 is the part through which vibrations are last transmitted from the vertical frame member 21 to the fixed reinforcement bracket 100, and so does not need to have strong cushioning properties, but is designed to be highly watertight to prevent water from entering the interior of the roof material R through the connecting hole 11b of the roof material R through which the screw B is inserted.

[0037] In this way, the type or thickness of the material of the first cushioning material 61 used on the first contact surface 31 and the second cushioning material 62 used on the second contact surface 51 can be changed as appropriate depending on the purpose, use, vibration amplitude, or vibration frequency.

[0038] Example 1 When using the fixing reinforcing bracket 100, the fixing reinforcing bracket 100 is attached to the vertical frame member 21 at regular intervals, as shown in the installation structure 110 in Figure 3. In this embodiment, the fixing reinforcing bracket 100 is attached to one of the protrusions 23 on the left side of the vertical frame member 21. By attaching the fixing reinforcing bracket 100, even if the vertical frame member 21 vibrates left and right, the mountain-shaped leaf spring portion 41 exerts an elastic force in the direction opposite to the left and right movement of the vertical frame member 21, thereby cushioning the vibration of the vertical frame member 21 and eliminating load on the screw B, which acts to prevent the screw B that secures the board 11 from loosening.

[0039] Even if the fixing reinforcing bracket 100 is not attached to one of the protrusions 23 on the left side, it may be attached to the other protrusion 24 on the right side, and even if the fixing reinforcing bracket 100 is not attached to the vertical frame member 21, it may be attached to the horizontal frame member 22. By attaching the fixing reinforcing bracket 100 to the horizontal frame member 22, it is possible to buffer vibrations transmitted from the horizontal frame member 22 to the vertical frame member 21, making it difficult for vibrations to be transmitted from the vertical frame member 21 to the fixing member 10 and roof material R, reducing load on the screws B and preventing the screws B that secure the substrate 11 from loosening.

[0040] Example 2 As shown in the installation structure 120 of Figure 4, the fixing reinforcement bracket 100 may be installed so that it is hooked onto both the protrusions 23 on the left side of a single vertical frame member 21 and the other protrusion 24 on the right side. In this embodiment, the left and right fixing reinforcement brackets 100 are fixed with a vertical offset. By attaching the fixing reinforcement brackets 100 to the vertical frame member 21 from both the left and right directions, left and right vibrations can be damped evenly compared to Example 1.

[0041] Example 3 As shown in the installation structure 130 in Figure 5, the fixing reinforcement brackets 100 are installed so that they are hooked onto the protrusions 23, 24 from the left and right sides of the vertical frame member 21, and the left and right fixing reinforcement brackets 100 are installed so that they face each other. The left and right fixing reinforcement brackets 100 are also installed in positions on the vertical frame member 21 that are midway between adjacent fixing members 10. Since the amplitude of vibration increases near the midpoint between adjacent fixing members 10, installing them near the midpoint allows for more even damping of left and right vibrations compared to Example 2.

[0042] [Second embodiment] 6 and 7, the leaf spring portion 40 of the fixing reinforcement bracket 200 according to the second embodiment is a parallel leaf spring portion 42. The fixing reinforcement bracket 200 has a connecting portion 30, a parallel leaf spring portion 42, and an attachment portion 50 molded continuously and integrally, and cushioning material 60 is provided on the surface of the connecting portion 30 facing the roof material R and on the surface of the attachment portion 50 facing the frame material 20. The connecting portion 30, attachment portion 50, and cushioning material 60 are the same as those of the fixing reinforcement bracket 100 according to the first embodiment, and only the leaf spring portion 40 is different.

[0043] (Parallel type leaf spring portion 42) As shown in Figures 6 and 7, the parallel plate spring portion 42 has a roughly U-shape when viewed from the side, and has two parallel plates 42a parallel to the roof material R and a connecting plate 42b connecting the ends of the parallel plates 42a.

[0044] 7, the two parallel plates 42a are an upper parallel plate 42c located above and a lower parallel plate 42d located below. A first inflection point 42e is formed at the joint between the upper parallel plate 42c and the connecting plate 42b, and a second inflection point 42f is formed at the joint between the lower parallel plate 42d and the connecting plate 42b. An attachment portion 50 is connected to the end of the upper parallel plate 42c that is not joined to the connecting plate 42b, and a rising plate 32 that connects to the end of the coupling portion 30 is joined to the end of the lower parallel plate 42d that is not joined to the connecting plate 42b.

[0045] The connecting plate 42b is formed to be shorter and more rigid than the parallel plate 42a. When vibration is propagated from the mounting portion 50, an elastic force acts as a restoring force on the upper parallel plate 42c and the lower parallel plate 42d at the first inflection point 42e and the second inflection point 42f to keep the angle between the connecting plate 42b and the parallel plate 42a at a right angle. As a result, even if the vertical frame member 21 moves up and down, an elastic force acts in the opposite direction to that direction, cushioning the up and down vibration propagated from the vertical frame member 21.

[0046] The parallel leaf spring portion 42 buffers the vibrations transmitted from the vertical frame member 21, preventing the vibrations from being transmitted from the vertical frame member 21 to the fixing member 10 and the roof material R, thereby eliminating load on the screw B and preventing the screw B that fixes the substrate 11 from loosening.

[0047] Furthermore, as in the first embodiment, the fixing reinforcing bracket 200 is fixed to the roof material R so as to bias the vertical frame member 21 in the direction of the roof material R. By fixing the fixing reinforcing bracket 200 so as to press down on the vertical frame member 21 from above, it is possible to further prevent the vertical frame member 21 from vibrating in the up and down direction, and it acts to prevent the screws B, which fix the substrate 11, from loosening.

[0048] As in the first embodiment, the parallel leaf spring portions 42 are not in contact with the roof material R and the vertical frame members 21. By making them not in contact, the vibration energy transmitted from the vertical frame members 21 does not act on the roof material R and the vertical frame members 21, but is converted into elastic energy by the roof material angle-shaped leaf spring portions 41 and is confined within the system, cushioning the vibration and preventing it from being transmitted from the vertical frame members 21 to the fixing member 10 and the roof material R, thereby reducing the load on the screws B that secure the base plate 11.

[0049] The horizontal length, depth length, and thickness of the parallel plates 42a, and the vertical length of the connecting plate 42b can be changed as appropriate depending on the amplitude and frequency of the vibration. In this embodiment, the connecting plate 42b is a straight plate, but it may also be curved.

[0050] Example 1 When using the fixing reinforcing brackets 200, they are attached to the vertical frame member 21 at regular intervals, as shown in the installation structure 210 in Figure 8. In this embodiment, the fixing reinforcing bracket 200 is attached to one of the protrusions 23 on the left side of the vertical frame member 21. By attaching the fixing reinforcing bracket 200, even if the vertical frame member 21 vibrates left and right, the fixing reinforcing bracket 200 exerts an elastic force in the direction opposite to the up and down movement of the vertical frame member 21, thereby cushioning the vibration of the vertical frame member 21 and eliminating load on the screws B, preventing the screws B that secure the board 11 from loosening.

[0051] The fixing reinforcing bracket 200 may not be attached to one of the protrusions 23 on the left side, but may be attached only to the other protrusion 24 on the right side, or may be attached not only to the vertical frame member 21 but also to the horizontal frame member 22. By attaching the fixing reinforcing bracket 200 to the horizontal frame member 22 as well, it is possible to buffer vibrations transmitted from the horizontal frame member 22 to the vertical frame member 21, preventing vibrations from being transmitted from the vertical frame member 21 to the fixing member 10 and roof material R, eliminating load on the screws B and preventing the screws B that secure the substrate 11 from loosening.

[0052] Example 2 Furthermore, as shown in an installation structure 220 in Fig. 9, the fixing reinforcement bracket 100 according to the first embodiment and the fixing reinforcement bracket 200 according to the second embodiment may be provided together. In this example, the fixing reinforcement bracket 100 is provided on the right side of the vertical frame member 21, and the fixing reinforcement bracket 200 is provided on the left side. These two brackets each provide superior damping of left-right and up-down vibrations, so by using both fixing reinforcement brackets 100, 200 simultaneously, it is possible to provide superior damping of diagonal vibrations that are a combination of left-right and up-down vibrations.

[0053] Furthermore, similar to Examples 2 and 3 of the fixing reinforcing metal fitting 100 according to the first embodiment shown in Figs. 4 and 5, the fixing reinforcing metal fitting 200 may be attached to the vertical frame member 21 from both the left and right sides.

[0054] <First feature> The first feature of this embodiment is that the fixing reinforcement bracket is not only a fixing member for fixing a longitudinal rod-shaped frame material that supports a solar panel to a roof material, but also a bracket that further reinforces and fixes the frame material to the roof material, and is characterized by having a connecting portion that is provided with a connecting hole for inserting a fastening member and connects to the roof material, an attachment portion that holds the frame material from above and attaches it, a leaf spring portion that connects the attachment portion and the connecting portion without contacting the roof material or the frame material and cushions vibrations transmitted from the attachment portion to the connecting portion, and sheet-shaped cushioning material on a first contact surface of the connecting portion on the roof material side and a second contact surface of the attachment portion on the frame material side.

[0055] According to the first feature, the leaf spring is fixed between the frame and the roofing material, which can buffer vibrations in the frame and prevent the screws in the existing fixing members from loosening. Furthermore, because the leaf spring is not in contact with the roofing material or the frame, vibration energy transmitted from the frame to the leaf spring is contained within the system without being transmitted to the roofing material or the frame, buffering vibrations and reinforcing the fixing member to fix the frame to the roofing material.

[0056] <Second feature> The third feature of the fixed reinforcing bracket of this embodiment is that the leaf spring portion is a mountain-shaped leaf spring portion having a first inclined plate rising from the connecting portion and a second inclined plate connecting from the end of the first inclined plate to the mounting portion.

[0057] According to the second feature, since the leaf spring portion is a mountain-shaped leaf spring portion, an elastic force acts in the direction opposite to the direction in which the frame material moves left and right, thereby cushioning left and right vibrations transmitted from the frame material.

[0058] <Third feature> The third feature of the fixing reinforcement fitting of this embodiment is that the leaf spring portion is a parallel leaf spring portion that is approximately U-shaped and has two parallel plates that are parallel to the roof material and a connecting plate that connects the ends of the parallel plates.

[0059] According to the third feature, since the leaf spring portion is a parallel type leaf spring portion, an elastic force acts in the opposite direction to the vertical movement of the frame material, thereby cushioning the vertical vibrations transmitted from the frame material.

[0060] <Fourth feature> The fourth feature of this embodiment is the installation structure of the fixing reinforcement bracket, which is characterized in that a fixing reinforcement bracket for a solar panel frame material described in claim 2 and a fixing reinforcement bracket for a solar panel frame material described in claim 3 are installed on one of the frame materials.

[0061] According to the fourth feature, a single frame member is provided with a fixed reinforcing bracket that uses a mountain-shaped leaf spring portion for the leaf spring portion, and a fixed reinforcing bracket that uses a parallel leaf spring portion for the leaf spring portion, so that vibrations in not only the up-down and left-right directions but also diagonal directions can be damped, making it possible to damp vibrations in any direction.
