Description

[Technical field]

[0001] The present invention relates to mounting hardware for roof-mounted objects, and more specifically, to technology for mounting hardware for roof-mounted objects that reduces manufacturing costs by using extruded material whose cross-sectional shape does not change as the main components, and that is versatile enough to accommodate roof materials of various shapes arranged in a direction approximately perpendicular to the ridge-eaves direction. [Background technology]

[0002] In 2015, the United Nations adopted the 2030 Agenda for Sustainable Development, which sets out sustainable development goals (SDGs) related to energy, economic growth and employment, climate change, etc., and in the same year, the Paris Agreement came into force, aiming to achieve a balance between anthropogenic greenhouse gas emissions and removal by carbon sinks in the second half of this century, and the importance of renewable energy that contributes to decarbonization has increased worldwide. In Japan, too, the Prime Minister announced in October 2020 that "we aim to achieve carbon neutrality and a decarbonized society by 2050," and the country and companies have begun to move toward achieving carbon neutrality. Furthermore, the government has set a target of increasing the proportion of renewable energy in power generation to "50%-60%" by 2050, three times the current level, marking a major shift in energy policy from fossil fuels to renewable energy.

[0003] In Japan, the proportion of renewable energy in the total power generation in fiscal year 2022 is expected to be 22.7%, of which solar power generation accounts for 9.9%, making it the major energy source. However, in order to promote the large-scale introduction of renewable energy, it is necessary to further promote the spread of solar power generation as a distributed power source that can be used for a wide range of purposes, such as in homes, factories, and power plants.

[0004] In addition, in Japan, where the land area is small, solar power generation module panels are often installed on the roofs of ordinary homes and factories. When installing such panels, the roof must be securely secured so that they will not be blown away by strong winds, even in the event of a direct hit from a typhoon. Therefore, when installing such panels, it is necessary to use high-strength mounting brackets that can withstand these winds. Moreover, such mounting brackets are required to be versatile enough to be compatible with various types of roofing materials with various shapes. Needless to say, weather resistance and cost must also be taken into consideration.

[0005] In view of this situation, various technical proposals have been made in the past. The title of the invention is "Mounting structure for solar cell module on folded plate roof", the problem to be solved is "to provide a mounting structure for solar cell module on folded plate roof that can increase the degree of freedom in designing the installation position of the solar cell module, eliminate the need for reinforcing the folded plate roof, facilitate construction, and realize low cost", and the specific solution is "The roof is made of a seam-type folded plate roof 1, the mounting bracket 2 has a seam gripping part 4 that grips and fixes the seam part 1a of the folded plate roof 1, and a receiving part 5 that receives the outer frame 3a of the solar cell module 3 from below, the male screw rod part 9 that stands up from this receiving part 5 is passed through the screw through hole 6a of the holding part 6, and the first nut 11 is screwed and tightened from above the holding part 6, so that the outer frame 3a is sandwiched between the receiving part 5 and the holding part 6 and fixed to the mounting bracket 1." However, this technique is thought to require bending or pressing of plate material, and since the processing is required in many places, the manufacturing burden and cost burden of the components is large.

[0006] In addition, the title of the invention is "Support device for structure on base, adjustable support body and support structure," the problem to be solved is "To provide a support device for a structure on a base which can stably install any superstructure at a distance above the roof of a building, an existing veranda, terrace, floor, shelf, or other base body," and the specific solution is "A support device which positions and supports a superstructure at a distance above the base body 12, and includes a plurality of adjustable support bodies 14 which are installed on the base body 12 and are integrated with each other and have a fixed part 16 to the base body 12 and a receiving part 18 which receives the superstructure. The adjustable support bodies 14 have a displacement support mechanism which displaces the receiving part 18 side within a predetermined range and supports the superstructure in that displaced state. The receiving part side can be freely adjusted in height up and down, adjusted around the vertical axis, and swung around the horizontal axis." The technology in question employs a configuration in which at least the height position of the receiving part is variably set by a displacement support mechanism, and the height position adjustment is performed for each of the point-like support bodies at the support positions of the dispersedly arranged point-like support bodies when supporting the upper structure in a planar manner, making it possible to perform the posture, gradient, surface finishing, etc. of the upper structure with high precision, and has the same effect as the present invention in that the pair of clamping bodies rotate around the insertion axis and can respond even if the installation on the roof is bent or tilted. However, if a bending force is applied to the upper and lower screw-on parts of the long nut connecting the upper and lower parts, there is a possibility that the threads will collapse.

[0007] In addition, the title of the invention is "Mounting structure for solar cell module to folded plate roof", and the problem to be solved is "to provide a mounting structure for solar cell module to folded plate roof which allows high freedom in designing the installation position of the solar cell module, eliminates the need for reinforcing the folded plate roof, makes construction easy, and realizes low cost", and the specific solution is "The roof is made of a seam-type folded plate roof 1, and the mounting bracket 2 has a seam gripping portion 4 which grips and is fixed to the seam portion 1a of the folded plate roof 1, and a receiving portion 5 which receives the outer frame 3a of the solar cell module 3 from below, and a male screw rod portion 9 which rises from this receiving portion 5 is passed through a screw through hole 6a of the holding portion 6, and a first nut 11 is screwed and tightened from above the holding portion 6, so that the outer frame 3a is sandwiched between the receiving portion 5 and the holding portion 6 and fixed to the mounting bracket 1. There is no conventional stand." However, while this technology can be said to be an effective structure, particularly when the receiving portion of the engagement part has a small lateral protrusion, it cannot grip engagement parts whose receiving portion has a large lateral protrusion, and it must be said that it lacks the versatility that is one of the objectives of the present invention.

[0009] The present invention aims to provide a mounting bracket for a roof-mounted object that reduces manufacturing costs by using an extrusion molded product whose cross-sectional shape does not change as the main component, and that is versatile enough to accommodate roof materials of various shapes. [Means for solving the problem]

[0010] The present invention employs a configuration in which the insertion shaft, the inner rotation connecting portion, and the outer rotation connecting portion are rotatably connected to form annular layers.

[0011] A swing grip part used in a metal fitting for mounting an object on a roof, the swing grip part having a pair of clamping bodies, an insertion shaft, and a fastening screw tool, one of the clamping bodies having an inner pivot connector at an upper end portion, the inner pivot connector having an arc that prevents the insertion shaft from falling off, and through which the insertion shaft is inserted, and a clamping claw at a lower end portion for clamping an engagement portion of a roof material, the other clamping body having an arc at an upper end portion, the inner pivot connector having an arc that prevents the inner pivot connector from falling off, and through which the inner pivot connector is inserted It is also possible to adopt a configuration in which the insertion shaft, the inner pivot connecting part and the outer pivot connecting part are connected to each other in a ring-shaped manner so as to form a layered annular shape and are rotatably connected to each other. The one clamping body and the other clamping body perform a clamping action via the tightening screw tool, and either one clamping body or the other clamping body, or both, have an arc-shaped protrusion at the contact part with the tightening screw tool, and the insertion shaft, the inner pivot connecting part and the outer pivot connecting part are connected to each other in a ring-shaped manner so as to form a layered shape.

[0012] Also, a metal fitting for attaching an object to a roof is composed of the oscillating grip portion, a base portion, and a pressing portion, the base portion having at its upper portion a mounting platform for placing the object to be installed and a T-shaped groove for installing a fixing screw member, and at its lower portion a bearing portion for supporting the outer pivot connecting portion so that it can rotate freely within a predetermined angle range, and the pressing portion is configured with a fixing member for clamping and fixing the object to be installed placed on the mounting platform.

[0013] Furthermore, the present invention may employ a configuration in which the swing grip portion, the base portion, and the pressing portion are each formed from a material whose cross-sectional shape in one direction does not change.

[0014] Furthermore, the present invention may employ a configuration in which a metal conductive fitting is provided between the base portion and the installation object. Effect of the Invention

[0015] According to the mounting bracket for a roof-mounted object of the present invention, the pair of clamping bodies, the base portion, and the pressing portion are all components that are configured in one direction and have a shape that does not change in cross section, so extruded material can be used, which has the excellent effect of reducing costs.

[0016] Furthermore, in the prior art, the insertion shaft is the part that is subjected to large wind loads, snow loads, and earthquake loads, and is therefore prone to deformation and damage. However, with the mounting bracket for a roof-mounted object of the present invention, the insertion shaft is reinforced by being wrapped in multiple layers by the inner pivot connecting part, the outer pivot connecting part, and the bearing part, thereby providing the excellent effect of significantly improving the load-bearing strength.

[0017] Furthermore, with the mounting bracket for a roof-mounted object of the present invention, the pair of clamping bodies can rotate by the insertion shaft, and even if the object to be installed on the roof is slightly bent, it can be fixed in a deformed state accordingly, thereby providing the excellent effect of being able to fix the object in accordance with its condition.

[0018] In addition, the mounting bracket for a roof-mounted object according to the present invention has the excellent effect of being highly versatile, being able to accommodate a wide variety of shapes of roof materials, such as interlocking folded plates.

[0019] Furthermore, when the mounting bracket for a roof-mounted object according to the present invention is made of 6000 series aluminum alloy, it has excellent extrusion properties, is highly weather resistant, has sufficient strength, and is lightweight, resulting in excellent workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The present invention has a major feature in that the insertion shaft, the inner rotation connecting part, and the outer rotation connecting part are connected to each other in a ring-shaped layer so as to be freely rotatable. The following description will be given based on the drawings. However, the present invention is not limited to the shapes and configurations shown in the drawings, and may be modified within the scope of the effects of the invention as a creation of the technical idea.

Figs. 1(a) and 2(a) are front views, and Figs. 1(b) and 2(b) are side views.

[0023] The main feature of the roof installation fitting 1 of the present invention is that the insertion shaft, the inner rotating connector, and the outer rotating connector are connected to each other in a ring-shaped layer so as to be freely rotatable. The following description will be given based on the drawings. However, the shape and configuration are not limited to those shown in the drawings, and may be modified within the scope of the effect of the invention as a creation of the technical idea. Each component will be described below.

[0024] The oscillating grip portion 10 is composed of a pair of clamping bodies 11, an insertion shaft 12, and a tightening screw tool 13, and the pair of clamping bodies 11 clamp the engagement portion K of the folded plate roof, thereby fixing the roof-mounted object mounting bracket 1 of the present invention to the roof material Y.

[0025] The pair of clamping bodies 11 are components that make up the swing grip portion 10, and are composed of one clamping body 14 and the other clamping body 17 that are rotatably hung by an inner rotating connecting part 15 through which the insertion shaft 12 is inserted and an outer rotating connecting part 18 into which the inner rotating connecting part 15 is inserted. The pair of clamping bodies 11 perform a tightening operation using the tightening screw tool 13, and clamp and hold the roof material Y with each clamping body.

[0026] The insertion shaft 12 serves as a base shaft for vertically setting up the pair of clamping bodies 11, and is inserted into the inner rotation connecting portion 15 of one of the clamping bodies 14, and is a so-called bolt having a bolt head on one end and a screw portion on the other end. The screw portion allows for fixing by tightening it to the base portion 20 with a nut.

[0027] The fastening screw tool 13 is a so-called bolt. It is made of a pair of clamping bodies 11, one of which is a clamping body 14 and the other of which is a clamping body 17, and is pulled together to clamp and grip, and conversely, can be pulled apart to remove.

[0028] One of the clamping bodies 14 is one of the pair of clamping bodies 11, and has an inner rotating connection part 15 at its upper end, which has an arc that prevents the insertion shaft 12 from falling off and through which the insertion shaft 12 is inserted, and a clamping claw 16 at its lower end for clamping the roof material Y. Since there is no hollow part and the cross section is a solid shape that does not change in cross section in one direction, an extrusion molding material can be used, and since there is no hollow part, a die for solid shaped material can be used in the die used for extrusion, and a hollow die for hollow shaped material is not required, and the die can be manufactured at low cost. By making it into such a shape and using 6000 series aluminum alloy as the material, it becomes suitable for extrusion molding. By using extrusion material for the main parts in this way, it is possible to reduce costs, reduce the number of processing steps compared to bending, and make a mounting bracket that is not affected by work hardening, etc.

[0029] The inner rotation connecting portion 15 is a portion through which the insertion shaft 12 is inserted and has an arc through which the insertion shaft 12 does not fall off.

[0030] The clamping claw 16 is a claw provided on the lower end of either the clamping body 14 or the other clamping body 17, and specifically, the lower tip of the clamping body is folded back so that it can firmly grasp the engagement portion K of the folded plate roof.

[0031] The other clamping body 17 is the other of the pair of clamping bodies 11, and has an outer rotating connector 18 at its upper end, which has an arc that prevents the inner rotating connector 15 from falling off and into which the inner rotating connector 15 is inserted, and a clamping claw 16 at its lower end for clamping the roof material Y. The clamping claw 16 has a solid cross section with no hollow portion, and the cross section does not change in one direction, so that an extrusion molding material can be used. Furthermore, since there is no hollow portion, a die for solid shaped material can be used in the mold used for extrusion, and a hollow die for hollow shaped material is not required, so that the mold can be manufactured at low cost. By using such a shape and a 6000 series aluminum alloy as the material, it becomes suitable for extrusion molding. By using an extrusion material for the main part in this way, it is possible to reduce costs and to produce a mounting bracket that does not suffer from strength defects such as processing effects compared to bending processing.

[0032] The outer pivot connecting part 18 is provided at the upper end of the other clamping body 17 with an arc that prevents the inner pivot connecting part 15 from falling off, and has a hole for inserting the inner pivot connecting part 15. When assembling, the inner pivot connecting part 15 provided on one of the clamping bodies 14 is inserted into the inner part, and the bearing part 22 of the base part 20 or the like is inserted into the outer part.

[0033] The R-shaped protrusion 19 is an arc-shaped bulge provided in the vicinity of the nut tightening portion of the tightening screw tool 13 in the clamping body. It is provided so that when the pair of clamping bodies 11 grips the engagement portion K of the roofing material, the clamping can be performed without being affected by the shape of the roofing material Y, such as when the gripping width is wide or narrow.

[0034] The base part 20 has a mounting table 21 on which the object S is placed at the top, and a bearing part 22 on which the swing grip part 10 is vertically attached at the bottom. Since the cross-sectional shape does not change in one direction, extrusion molding material can be used. The base part 20 has a hollow part, but a hollow die can be used. Since the shape is not complicated, the mold can be manufactured at low cost. By using such a shape and a 6000 series aluminum alloy as the material, it becomes suitable for extrusion molding. By using extrusion material for the main parts in this way, it is possible to reduce costs and to produce a mounting bracket that does not suffer from strength defects caused by work hardening or residual distortion, etc., compared to bending or cutting.

[0035] The mounting table 21 is a flat surface protruding outward and provided on the upper surface of the base section 20 in order to place the object S on it. When the object S is placed on the mounting table 21, the insertion shaft 12, the inner rotating connector 15, and the outer rotating connector 18 rotate in response to the bending or deformation of the object, and the object can be held in a tilted state as shown in FIG.

[0036] The bearing portion 22 is a receiving portion having an arc that prevents the outer rotation connecting portion 18 from falling off, and into which the swinging grip portion 10 is inserted and vertically supported.

[0037] The fixing screw member 23 is a so-called bolt, and the head of the bolt is inserted into the T-slot 24 of the base portion 20 to stand upright, and the T-slot 24 is formed approximately at the center of the base portion 20 on the mounting base 21 with a nut as a screw member to hold it down, and the bolt head of the fixing screw member 23 is inserted into the T-slot 24 and fixed in an upright state with a nut, and the upper screw portion tightens and fixes the installation object S.

[0038] The T-shaped groove 24 can be formed by extrusion molding, which reduces costs. Furthermore, the T-shaped groove 24 is a groove that allows the fixing screw member 23 to stand upright without dropping.

[0039] The holding part 30 is a member that clamps and fastens the installation object S between the upper surface of the base part 20 or the conductive metal fitting by the fixing screw member 23, and there are cases where the installation object S is on both sides and cases where the end of the installation object S is held down. In such cases, the shape of the fixing member is changed to that shown in Figures 1 and 2 or Figures 3 and 4.

[0040] The fixing member 31 is a member that constitutes the pressing part 30. It is a member that clamps the installation object S placed on the upper surface of the mounting table 21 to the base part 20 with the fixing screw member 23, and there are two types, one for the end part and one for the middle part, as shown in Figures 1, 2, 3, and 4. The fixing member 31 is fastened by the fixing screw member 23 that is erected on the base part 20 and a nut that screws into the fixing screw member 23.

[0041] When the metal conductive metal fitting 40 is used in the mounting bracket 1 for the rooftop installation according to the present invention, it plays a role of connecting two adjacent installations S and making them conductive due to its excellent conductivity. Specifically, the difference is clear when compared with the case of connecting the housings of multiple adjacent solar panels with an earth wire. That is, it can contribute to simplifying the production and installation of the earth wire and reducing the labor required. It is preferable that the conductive metal fitting is provided with a biting protrusion 32 that breaks the coating on the treated surface of the installation S and bites into it. This is because the type of surface treatment, such as a coating or an anodized coating, applied to the installation S, such as the housing, may hinder conductivity.

[0042] The installation object S is a frame or the like in which a module such as a solar panel is installed. The frame includes not only solar panels but also various rooftop installations. For example, solar hot water equipment is also included as an installation object S.

[0043] The roof material Y is a metal roofing member, typically a folded-plate roof, having an engagement portion K. FIG. 6 shows an example of the fact that the roof material Y can accommodate various shapes and sizes of the engagement portion K.

[0044] The engagement part K is a part that is clamped and gripped by the claws of a pair of clamping bodies 11 in a metal roofing member, such as a folded plate roof. In the case of a seam folded plate, it is the "seam" part where two metal roofing members are folded and joined, and in the case of a fitting folded plate, it is the joint part where a fastening part called an "fitting part" is stepped on to lock the metal plates together. In this document, these "seam parts" and "fitting parts" are collectively referred to as "engagement part K".

[0045] The 6000 series aluminum alloy A is a suitable material for the pair of clamping bodies 11, the base portion 20, and the pressing portion 30, and is an alloy in which Mg (magnesium) and Si (silicon) or Mg (magnesium), Si (silicon), and Cu (copper) are added to Al (aluminum). Among the 6000 series, the Al-Mg-Si heat-treated type 6063 is a representative extrusion alloy, which has excellent corrosion resistance and anodizing properties, and is most widely used in construction and other applications because it has a relatively simple heat treatment (called T5 treatment) of extrusion, air cooling, and aging, and can be formed into complex shapes. T5 is the most common temper, and T6 is used when bending is required and a little stronger than T5. 6061 is used in parts that require higher strength than 6063, and is widely used as a medium-strength structural material for trucks, shipping containers, etc. The corrosion resistance of 6061 is slightly inferior to that of 6063, but is still in the good category, and either material can be said to be suitable for the bracket 1 for mounting an object on a roof according to the present invention.

[0046] FIG. 5 is a diagram illustrating the use of the mounting bracket 1 for the roof-mounted object according to the present invention. FIG. 5 shows the state in which the object S is mounted on the folded-plate roof material Y using the mounting bracket 1 for the roof-mounted object according to the present invention, and the clamping part 30 is for the end. Note that there is a predetermined clearance at the joint between adjacent panels shown in the upper left of FIG. 5, and although not shown in the drawing, the panels are connected and held by using the intermediate clamping part 30 in the relevant part. In addition, if the housings are made conductive by using a metal conductive metal 40, there is no need to connect them with an earth wire as shown in FIG. 6.

[0047] FIG. 6 is an explanatory diagram of a usage state illustrating an example of a roof material Y that can be used with the mounting bracket 1 for a roof installation according to the present invention, and FIG. 6(a) to FIG. 6(l) show that it can be adapted to the shape (size and size of width) of the engagement part K of various folded plate roof materials. Specifically, for example, the width of the engagement part K of the roof material Y shown in FIG. 6(j) is narrow, at only about 25 mm. In contrast, the width of the roof material Y shown in FIG. 6(f) is wide, at about 66 mm. In other words, it can be adapted to a wide range of widths of the engagement part K, which shows its high versatility.

[0048] FIG. 7 is an explanatory diagram illustrating the state in which, when the object S to be installed is placed on the mounting base 21, the insertion shaft 12, the inner rotating connecting portion 15, and further the outer rotating connecting portion 18 rotate about the axis of the insertion shaft 12 in response to the bending or deformation of the object S to be installed, and the object S sways as shown in FIG.

[0049] Fig. 8 is a comparative explanatory diagram of a configuration in which a rounded protrusion 19 is provided at the contact portion between the clamping body and the fastening screw 13 that loosely fits and fastens the clamping body, and a configuration in which it is not provided, Fig. 8(a) shows a configuration in which the rounded protrusion 19 is not provided and the engagement portion K is wide, Fig. 8(b) shows a configuration in which the rounded protrusion 19 is not provided and the engagement portion K is narrow, Fig. 8(c) shows a configuration in which the rounded protrusion 19 is provided and the engagement portion K is wide, and Fig. 8(d) shows a configuration in which the rounded protrusion 19 is provided and the engagement portion K is narrow. As shown in Fig. 8, in the configuration in which the rounded protrusion 19 is not provided, the nut tries to be fastened obliquely with respect to the screwing portion of the bolt whether the engagement portion K is wide or narrow, so the thread is likely to collapse. In contrast, in the case of a configuration in which an arched protrusion 19 is provided, tightening can be performed regardless of whether the engagement portion K of the roof material is wide or narrow, and the threads of the bolt screw-in portion and the nut are less likely to become disintegrated.

[0050] (assembly) The inner rotating connector 15 provided at the upper end of one of the clamping bodies 14 is inserted into the outer rotating connector 18 provided at the upper end of the other clamping body 17. Next, the outer rotation connector 18 through which the inner rotation connector 15 has been inserted is inserted into the bearing portion 22 of the base portion 20 . Next, the insertion shaft 12 is inserted into the inner rotation connecting portion 15, and is screwed in place using a flat washer, a spring washer, or the like, and a nut. Next, holes are drilled in the one clamping body 14 and the other clamping body 17, and the tightening screw 13 is passed through the holes, and provisionally assembled with flat washers, spring washers, etc., and nuts. Next, the head portion of the fixing screw member 23 is inserted into the T-shaped groove 24 of the base portion 20 so as to stand upright from the mounting table 21, and the fixing screw member 23 is inserted into the metallic conductive metal fitting 40. (attachment) The nuts of the provisionally assembled fastening screws 13 are loosened. Next, the engaging portion K of the roof material Y is clamped between the clamping body 14 on one side and the clamping body 17 on the other side, and the fastening screw 13 is fastened with a nut. Next, the object S to be installed, such as a solar panel, is placed on the mounting base 21, and the object S is clamped by the fixing members 31 and the nuts are tightened to complete the installation.

[0051] In the conventional technology, the insertion shaft is subject to large wind loads, snow loads, and earthquake loads, and is therefore prone to deformation and damage. In the present invention, the insertion shaft is reinforced by being wrapped in multiple layers with the inner rotating connector 15, the outer rotating connector 18, and the bearing 22, significantly improving the load-bearing strength. [Industrial Applicability]

[0052] The mounting bracket for roof-mounted equipment of the present invention makes it safe to install power generation modules on roofs, including those of ordinary houses, in the field of solar power generation, which is expected to see increasing demand in the future as an alternative energy source to fossil fuels, and it is also possible to reduce economic costs, so it is believed to have great industrial applicability in the construction field.
