Description

Technology Field

[0001] The present invention relates to a construction support for a photovoltaic power generation module with secured support stability, and more specifically, to a structure that is fixedly installed at standardized intervals on the upper part of a roof panel supported by a structural steel formed on the ceiling of a building to enable safer construction of a module frame constituting a photovoltaic power generation module on the roof of a building, and in particular, by configuring the structural steel and the base plate to be directly supported, thereby preventing the roof panel from sinking or deforming due to the load of the photovoltaic power generation module including the module frame, the invention relates to a construction support for a photovoltaic power generation module with secured support stability that ensures improved durability and watertightness. Background Technology

[0002] With the recent rapid increase in demand for the expansion of renewable energy and the desire to increase energy self-sufficiency in buildings, there has been a significant rise in cases where solar panels are installed on roofs to generate electricity.

[0003] In particular, installation methods that utilize the roof panel structure to secure brackets are widely used in roof panel structures, such as metal or steel plate roofs.

[0004] However, such conventional installation methods have the following structural problems.

[0005] First, during the process of securing the bracket to the protruding roof panel, there is a high risk of rainwater or condensation penetrating through fastening screws, rivets, or gaps between the bracket and the roof.

[0006] In particular, since the entire roof is sloped, there is a high possibility that water will seep into every nook and cranny, and if it accumulates over a long period, the damage could spread to the interior of the building.

[0007] Conventional technology generally attempts to compensate for these problems by using waterproof silicone, rubber gaskets, etc., to prevent leakage; however, due to external exposure, aging deteriorates rapidly, and waterproofing performance can rapidly deteriorate under repeated changes in temperature and humidity.

[0008] Furthermore, conventional bracket structures often do not provide a sufficiently robust engagement with the roof panel protrusion (R) or rely only on certain bolt fastening points. Consequently, there is a risk that the bracket itself may shake or slide sideways when subjected to external forces such as strong winds, wind loads, snow loads, or vibrations.

[0009] If the bracket shakes like this, it not only causes cracks and damage to the solar panels but also leads to damage to the waterproofing layer inside the roof and additional leaks.

[0010] Meanwhile, as metal roofs are irregular in shape and vary in slope angles and curves, conventional bracket systems often require on-site custom cutting, bending, and fastening. This necessitates the addition of extra reinforcement if multiple separate parts are required or if precise connections cannot be achieved depending on the installation location and angle. Such complex construction procedures lead to increased installation costs and delays, inevitably resulting in reduced reliability of the brackets even after completion.

[0011] In addition, conventional technology mainly involves simply overlapping the joints between brackets and roofs, or between brackets themselves, or fixing them only with rivets and bolts. However, structurally, the rainwater drainage path is not smooth, causing water to accumulate at the joints. It is also difficult to check for internal damage when leakage occurs, and during maintenance, it is difficult to replace parts, making it highly likely that the entire bracket must be dismantled or re-installed.

[0012] To resolve these issues, a structure must be provided in which the roof panels and brackets interlock precisely to fundamentally reduce the risk of leakage, provide robust support without shaking even under external wind loads or vibrations, and allow for easy installation and maintenance.

[0013] (Patent Document 0001) KR 10-193721 B1 The problem to be solved

[0014] The objective of the present invention, devised to resolve the aforementioned problems, is to provide a construction support for a photovoltaic power generation module with secured support stability, which prevents local deformation such as sinking of the roof panel and ensures watertight stability by dispersing the pressure applied to the roof panel located between the steel section and the base plate due to the load of the photovoltaic power generation module including the module frame by configuring the steel section and the base plate to be directly supported. means of solving the problem

[0015] The above objective is achieved by the following configuration provided in the present invention.

[0016] A construction support for a photovoltaic power generation module with secured support stability according to the present invention is,

[0017] Fixedly installed at each point of the roof panel of a building where the installation of solar power generation modules is required, and the module frames of the solar power generation modules are stacked and fixed on the top of the roof panel,

[0018] A base plate comprising: an assembly sheet portion on which a module frame of a photovoltaic power generation module is assembled; and a support portion integrally formed on both the left and right sides of the assembly sheet portion, which covers a protruding section formed on a roof panel whose bottom surface is supported by structural steel members, and which has a fixing hole formed in communication with the assembly hole of the roof panel protruding section and the assembly hole of the structural steel member.

[0019] A bolt assembly comprising a fixing bolt that sequentially penetrates and fixes the assembly hole of the protruding section of the roof panel and the assembly hole formed in the structural steel along the fixing hole of the base plate, thereby stacking and fixing each support member of the base plate on the protruding section of the roof panel supported by the structural steel; and

[0020] It is configured to include a reinforcing support member that supports a supporting end of a base plate stacked on top of a roof panel and a structural steel member that supports the lower part of the roof panel, by being arranged concentrically within an assembly hole formed in the roof panel and assembled to vertically penetrate the fixing bolt of the bolt assembly.

[0021] The above reinforcing support is positioned between the base plate stacked on the upper part of the roof panel and the structural steel placed on the lower part of the roof panel, so as to distribute and transfer the load applied to the base plate to the structural steel.

[0022] The above reinforcing support is composed of a support tube body formed by cutting a plurality of divided support pieces in a radial structure through a cut groove at the support end, and when pressure is applied to the support tube body by fastening the bolt assembly, the divided support pieces elastically bend to elastically support the space between the structural steel and the support portion of the base plate, thereby distributing the load applied to the roof panel to the structural steel.

[0023] The above-described reinforcing support is characterized by having a sealing layer forming bushing made of an elastic material provided within the support tube constituting the above-described reinforcing support, wherein the sealing layer forming bushing is compressed by the compression of the support tube to form a sealing layer.

[0024] Preferably, the bolt assembly comprises a fixing bolt having a fastening portion formed on the upper part and a fixing member installed as a hinge structure on the lower part, which sequentially passes through an assembly hole formed in the protruding section of the roof panel and an assembly hole formed in the structural steel while the fixing member is vertically aligned, and then the upright fixing member is rotated around a hinge axis to be horizontally aligned so as to be fixed to the structural steel; and a fixing nut that is fastened to the fastening portion of the fixing bolt and compresses and fixes the support portion of the base plate on the protruding section of the roof panel. Effects of the invention

[0025] As described above, in the present invention, the construction precision and structural stability of the photovoltaic power generation module are improved by being fixedly installed at standardized intervals on the upper part of a roof panel supported by a structural steel.

[0026] Furthermore, the stress directly applied to the roof panel by the photovoltaic power generation module installed by a reinforcing support having a unique support structure is dispersed, and as a result, local deformation or sagging of the roof panel is prevented, thereby ensuring stable durability and maintaining sufficient waterproofing performance.

Specific details for implementing the invention

[0029] Since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, embodiments are illustrated in the drawings and described in detail in this specification.

[0030] However, this is not intended to limit embodiments according to the concept of the present invention to specific disclosed forms, and includes all modifications, equivalents, or substitutions that fall within the spirit and scope of the present invention.

[0031] The construction support (100) for a photovoltaic power generation module with secured support stability, proposed as a preferred embodiment in the present invention, is a means for fixing and fixing the module frame (11) of the photovoltaic power generation module to the upper part of the roof panel (20) in a standardized manner, as shown in FIG. 1, by fixing it at each point of the roof panel (20) of a building where the construction of the photovoltaic power generation module (10) is required.

[0032] The above-mentioned roof panel (20) is composed of a panel body formed by alternating protruding sections (21) and recessed sections (22), and the protruding sections (21) of the roof panel (20) are installed in a state supported by a plurality of structural steel members (30) arranged on the ceiling of the building to prevent local deformation or sagging of the roof panel (20).

[0033] Hereinafter, a construction support for a photovoltaic power generation module with secured support stability, proposed as a preferred embodiment of the present invention, will be described in detail with reference to the attached drawings.

[0034] FIGS. 1 to 3 illustrate the construction state of a photovoltaic power generation module installed on a roof panel through a construction support proposed as a preferred embodiment of the present invention, FIG. 4 illustrates the detailed configuration of a reinforcing support in a construction support for a photovoltaic power generation module with secured support stability proposed as a preferred embodiment of the present invention, and FIGS. 5 to 7 illustrate the sequential construction process and detailed construction state of a construction support for a photovoltaic power generation module with secured support stability proposed as a preferred embodiment of the present invention.

[0035] A construction support (100) for a photovoltaic power generation module with secured support stability, proposed as a preferred embodiment in the present invention, comprises: an assembly sheet portion (111) on which a module frame (11) of a photovoltaic power generation module (10) is stacked and assembled as shown in FIGS. 1 to 3; and a base plate (110) including a support portion (112) which is integrally formed on both the left and right sides of the assembly sheet portion (11), stacks and covers a protruding section (21) formed on each roof panel (100) whose bottom surface is supported by structural steel (30), and has a fixing hole (112a) formed to connect the assembly hole (23) of the roof panel (100) protruding section (21) with the assembly hole (31) of the structural steel (30). The bolt assembly (130) includes a fixing bolt that sequentially penetrates and fixes the assembly hole (23) of the protruding section (21) of the roof panel (20) and the assembly hole (31) formed in the structural member (30) along the fixing hole (112) of the base plate (110), thereby stacking and fixing each support portion (112) of the base plate (110) on the protruding section (21) of the roof panel (20) supported by the structural member (30).

[0036] The above base plate (110) is composed of a bent molded product formed by bending a high-strength metal plate.

[0037] An elongated hole (111a) is formed in the assembly sheet portion (111) by cutting it left and right, and a module frame (11) that is stacked and aligned in an intersecting state on the assembly sheet portion (111) is installed in a standardized manner through the assembly sheet portion (111) by means of a binding fixing member (120) that is fixed through the elongated hole (111a).

[0038] At this time, the binding fixing member (120) moves left and right through the elongated hole (111a) formed in the assembly sheet part (111) to bind and fix the module frame (11) in the correct position.

[0039] And, the support members (112) integrally formed on both sides of the assembly sheet member (111) are bent and molded into a shape corresponding to the protruding section (21) of the roof panel (20), and are stacked and fixed in a state that completely wraps around the protruding section (21) of the roof panel (20).

[0040] At this time, the base plate (111) is fixed in a stacked state to support the support members (112) formed on both sides of the protruding section (21) of the roof panel (20), which is supported by the steel member (30), so the assembly sheet member (111) formed between the support members (112) is located in the recessed section (22) formed between the protruding section (21).

[0041] Accordingly, a vertically spaced mouth space (114) is formed between the recessed section (22) of the above-mentioned roof panel (20) and the assembly sheet section (111) of the base plate (110), and the installer can easily assemble the module frame (111) that is cross-aligned with the assembly sheet section (111) through the binding fixing member (120) while moving their hand or mouthpiece in and out along the mouth space (114).

[0042] Additionally, an extended support end (113) is integrally formed on the outer side of the support member (112) to support the surface of the recessed section (22) formed on both sides of the protruding section (21) of the roof panel (20), thereby dispersing some of the load applied to the protruding section (21) through the recessed section (22) formed on the outer side of the protruding section (21), so as to effectively prevent deformation or sagging of the roof panel (20) caused by load support of the base plate (110) and the photovoltaic power generation module (10) installed through the base plate.

[0043] In particular, unlike the recessed section (22) of the roof panel (20), the protruding section (21) is spaced vertically apart from the structural steel (30), so deformation such as local sagging may be exacerbated by the load applied by the base plate (110) and the solar power generation module (10).

[0044] The above bolt assembly (130) includes a fixing bolt (131) in which a fastening portion (131a) is formed on the upper side and a shoulder support (132) is installed in a hinge structure on the lower side, and the shoulder support (132) is vertically aligned and passes sequentially through the assembly hole (23) formed in the protruding section (21) of the roof panel (20) and the assembly hole (31) formed in the structural steel (30) along the fixing hole (112a), and then the upright shoulder support (132) is rotated around the hinge axis (131b) to be horizontally aligned and thus attached to the structural steel (30); and a fixing nut (136) which is fastened to the fastening portion (131a) of the fixing bolt (131) and press-fixes the support portion (112) of the base plate (110) on the protruding section (21) of the roof panel (20).

[0045] The shoulder rest (132) of the above-mentioned fixed bolt (131) is installed at the bottom of the fixed bolt (131) via a hinge shaft (131b) in an eccentric hinge structure and has a tendency to maintain a horizontally aligned state by rotating eccentrically.

[0046] Accordingly, the attachment member (132) of the attachment bolt (131) sequentially passes through the fixing holes (112a) and assembly holes (23, 31) that are aligned vertically and vertically, and then rotates eccentrically around the hinge axis (131b) to be horizontally aligned and attaches its lower end to the structural steel (30), so that construction can be performed in a single direction from the roof without separate access to the lower part, thereby significantly improving constructability.

[0047] In this way, the fixing portion (112) of the base plate (110) stacked on the protruding section (21) of the roof panel (20) is stacked, and a fixing bolt (131) is inserted and attached through the fixing hole (112a) aligned in an upper and lower row, the assembly hole (23) formed in the protruding section (21) of the roof panel (20), and the assembly hole (31) of the structural steel (30), and then a fixing nut (136) is fastened. When each fixing portion (112) of the base plate (110) is stacked and fixed on the protruding section (21) of the roof panel (20), the compressive force resulting from the fastening of the fixing bolt (131) and the fixing nut (136) is concentrated on the periphery of the assembly hole (23), and local deformation such as sinking of the roof panel (20) where the assembly hole (23) is formed may be caused.

[0048] When local deformation of the roof panel (20) occurs in this way, the support strength of the roof panel (20) itself is weakened, the support stability of the base plate (110) decreases, and rainwater may flow in along the periphery of the deformed assembly hole (22), causing leakage of the building.

[0049] In addition, physical damage to the roof panel (20) that has localized deformation may be exacerbated by vibrations or shocks applied from the roof panel (20) or the solar power generation module (10) installed on the roof panel (20) due to external wind or external vibrations.

[0050] To resolve this, in this embodiment, a reinforcing support (140) having a unique support structure is proposed and provided on the bolt assembly (130), thereby dispersing the physical load applied to the protruding section (21) of the roof panel (20) formed between the structural steel (30) and the base plate (10) by the reinforcing support (140).

[0051] The reinforcing support member (140) proposed in this embodiment is composed of a support tube (141) that penetrates the assembly hole (23) formed in the roof panel (20) as seen in FIGS. 4 to 7, and a fixing bolt (131) that is attached to the structural steel (30) through a shoulder bracket (132) penetrates vertically through the hollow portion of the support tube (141).

[0052] The above reinforcing support member (140) is arranged in a concentric structure within an assembly hole (23) formed in the roof panel (20) and assembled so that the fixing bolt (131) of the bolt assembly (130) penetrates vertically up and down, thereby supporting the structural steel (30) supporting the lower part of the roof panel (20) and the support portion (112) of the base plate (110) stacked and assembled on the upper part of the protruding section (21) of the roof panel (20) so as to be spaced apart vertically.

[0053] When configured in this way, the pressure applied vertically to the protruding section (21) of the roof panel (20) is distributed to the structural steel (30) by the reinforcing support (140), and as a result, local damage to the roof panel (20) is suppressed by fixing the support portion (112) of the base plate (110) to the protruding section (21) of the roof panel (20) through the bolt assembly (130), and in particular, physical damage to the roof panel (20) can be suppressed even when a high-load solar power generation module (10) is installed on the base plate (110).

[0054] Preferably, a flexible material adhesive layer forming bushing (144) is placed through the inner wall of the reinforcing support (140).

[0055] When configured in this way, the sealing layer forming member (144) placed within the reinforcing support is vertically compressed by the pressure resulting from the fastening of the fixing nut (136) as shown in FIG. 7, thereby forming a tight seal between the structural steel (30) and the reinforcing support (140), and between the support member (112) of the base plate (110) and the reinforcing support (140), and consequently sealing the assembly hole (23) formed in the roof panel (20) and the assembly hole (31) of the structural steel (30), thereby preventing rainwater from flowing into the ceiling of the building through these assembly holes (23, 31).

[0056] In addition, the compressed window layer forming member (144) is in close contact with the inner diameter surface of the fixing bolt (131) penetrating the reinforcing support (140), thereby preventing rainwater from flowing into the ceiling of the building through the fixing bolt (131).

[0057] More preferably, the reinforcing support (140) is composed of a support tube (141) in a form in which a plurality of divided support pieces (142) are cut in a radial structure at the support end (141a).

[0058] Accordingly, when a worker tightens the fixing nut (136) according to the thickness of the roof panel (20), the divided support pieces (142) expand elastically due to the pressure applied by the tightening, thereby elastically supporting the space between the structural steel (30) and the support portion (112) of the base plate (110) and dispersing the pressure applied to the protruding section (21) of the roof panel (20).

[0059] That is, the divided support pieces (142) formed on the support end (141a) of the reinforcing support member (140) are vertically extended in a non-bending state when in a non-compressed state, and when the reinforcing support member (140) is pressed vertically by the fastening force of the fixing nut (136), the divided support pieces (142) expand outward and elastically support the space between the structural steel (30) formed on the bottom surface of the roof panel (20) and the support portion (112) of the base plate (110) formed on the top surface of the roof panel (20).

[0060] In particular, in this embodiment, as shown in FIG. 4, a support strength adjusting rim (143) is further formed to adjust the elastic support strength of the divided support pieces (142) by supporting the divided support pieces (142) formed at the support end (141a) of the reinforcing support body (140) in an annularly compressed state.

[0061] According to the present embodiment, the support strength adjustment rim (143) is configured as a nut type that moves up and down along the support end (141a) while being fastened to a fastening section (141a-a) formed on the outer wall of the reinforcing support body (140), thereby adjusting the elastic support strength of the divided support piece (142) by moving up and down along the support end (141a) of the reinforcing support body (140) through fastening.

[0062] Accordingly, the worker appropriately sets the elastic support strength of the divided support piece (142) through the support strength adjustment rim (143) according to the construction conditions at the site, thereby supporting the space between the structural steel (30) and the base plate (110) with the required support strength.

[0063] That is, the worker adjusts the elastic support strength of the divided support pieces (142) through the support strength adjustment rim (143) by considering the thickness or strength of the roof panel (20), thereby providing a standardized support between the base plate (110) and the structural steel (30).

[0064] The embodiments of the present invention described above are merely illustrative of the technical concept of the present invention, and the scope of protection of the present invention should be interpreted by the following claims.

[0065] Furthermore, as those skilled in the art to which this invention pertains may make various modifications and variations within the scope of the essential characteristics of this invention, all technical concepts within the scope equivalent to this invention should be interpreted as being included within the scope of rights of this invention.
