Description

Technology Field

[0001] The present invention relates to a solar panel installation frame that distributes working load and prevents leakage, and more specifically, to a solar panel installation frame that distributes working load and prevents leakage that can be installed without changing the shape of existing roofing materials or drilling holes, while preventing roof damage and leakage caused by the load of workers during installation and maintenance. Background Technology

[0003] With the recent emergence of environmental issues and energy supply and demand concerns, the demand for solar power generation is surging. To meet this demand, the installation of solar power systems utilizing the roofs of existing buildings is expanding. The method of installing solar panels on the roofs of existing buildings has primarily involved perforating the roofing material to secure support frames.

[0004] However, this method carries a persistent risk of leakage due to the failure to maintain airtightness at the perforated areas, and in particular, worker-induced leakage is pointed out as a chronic problem caused by the separation of connecting parts of roofing materials, such as tiles or panels, as the load from workers' foot traffic is concentrated at specific points on the roof during installation and maintenance.

[0006] Patent Publication No. 10-2025-0027137, Patent Registration No. 10-2523431 The problem to be solved

[0007] The present invention aims to provide a solar power installation frame that distributes working load and prevents leakage, which can be installed without changing the shape of existing roofing materials or drilling holes, while preventing roof damage and leakage caused by the load of workers during installation and maintenance. means of solving the problem

[0009] A solar power installation frame according to the present invention for achieving the above objective comprises a shock-absorbing pad (120) that is in close contact with the upper surface of a roofing material (100), a load-distributing base (130) that supports a load on the upper part of the shock-absorbing pad (120), and a module coupling part (140) that is placed on top of the load-distributing base (130). The frame is configured to prevent damage to the roofing material and leakage by blocking the transmission of shocks or vibrations caused by a worker's walking to the connection part of the roofing material through the load-distributing base (130) and the shock-absorbing pad (120). Effects of the invention

[0011] The solar panel installation frame with work load distribution and leak prevention according to the present invention utilizes a clamping method using a C-shaped clamping unit and a load distribution base to prevent physical damage to the roof and safely guide the load to the main frame. It also more efficiently distributes the load of a worker walking on the roof material through the slope of the shock-absorbing pad, thereby preventing damage to the roof material caused by the worker's load. Furthermore, by rapidly draining moisture through the grid-shaped drainage grooves of the shock-absorbing pad, it is possible to expect effects that fundamentally block the risk of corrosion and leakage at the contact points.

[0012] In addition, the present invention has the effect of preventing the occurrence of gaps in roofing materials by efficiently separating and absorbing static self-weight and dynamic walking impact through a composite layer structure of a high-hardness upper layer and a low-hardness lower layer of the shock-absorbing pad, and in particular, can more efficiently prevent the occurrence of gaps in roofing materials by separating and absorbing static self-weight and dynamic walking impact even more efficiently through an auxiliary cushioning tube.

Specific details for implementing the invention

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The objectives, features, and advantages of the present invention will be more easily understood by referring to the attached drawings and the following detailed description. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the present invention, such detailed description is omitted.

[0016] In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. For example, where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected to or connected to the other component, but that another component may also be "connected," "combined," or "connected" between each component.

[0018] The solar panel installation frame according to the present invention, which distributes working load and prevents leakage, is characterized by enabling installation without drilling holes in the roof while preventing roof damage caused by the load of workers during maintenance.

[0019] To this end, the frame of the present invention comprises a shock-absorbing pad (120) disposed on the upper surface of a roofing material (100), a load-distributing base (130) that supports a load on the upper part of the shock-absorbing pad (120), and a module coupling part (140) that supports a solar module.

[0020] More specifically, the present invention comprises a shock-absorbing pad (120) that is in close contact with the upper surface of the roofing material, a base plate disposed on the upper part of the shock-absorbing pad (120) that supports the load of a worker to prevent the load from being concentrated at a specific point on the roof when a worker load occurs, and a module coupling part (140) disposed on the load-distributing base (130) to support a solar module, and is configured to prevent damage to the roofing material and leakage by blocking the transmission of shocks or vibrations caused by the worker's walking to the connection part of the roofing material through the lower roof distribution base and the shock-absorbing pad (120).

[0021] The load distribution base (130) prevents the load from being concentrated at a specific point on the roof when a worker walks.

[0022] The shock-absorbing pad (120) prevents damage and leakage by blocking the transmission of walking vibrations from the worker to the roof material connection area.

[0023] An auxiliary cushioning tube (150) is interposed between the load distribution base (130) and the shock absorption pad (120). This auxiliary cushioning tube (150) is interposed between the slope (122) of the shock absorption pad (120) and the bottom surface of the load distribution base (130). A plurality of cushioning hollows (152) are provided inside the auxiliary cushioning tube (150) to perform load distribution and cushioning functions by the auxiliary cushioning tube (150) itself, and a secondary cushioning material (154) is filled into the cushioning hollows (152) to cushion and distribute the load in stages.

[0024] Meanwhile, the present invention secures the main part, the shock absorption pad (120), and the load distribution base (130) through a C-shaped clamping unit (160) that does not drill holes in the roofing material. At this time, the module coupling part (140) can be secured on the load distribution base (130) by means of a separate fixing means such as a bolt and a bracket. For reference, a module mounting support piece protrudes from the inner side of the module coupling part (140), and the solar module can be secured to the module mounting support piece by means of a fixing means such as an adhesive or a fixing bolt while the solar module is placed on the module mounting support piece, thereby allowing the solar module to be coupled to the module coupling part (140). For reference, in the present invention, a solar module refers to a plurality of solar panels arranged in a grid shape and supported and coupled to a solar panel support frame.

[0025] In the present invention, the C-shaped clamping unit (160) is composed of a C-shaped clamp (162) and a clamping screw-shaped member (164).

[0026] The load distribution base (130) can be fixed with a C-shaped clamping unit (160) while the base-side edge frame (131) of the load distribution base (130) is positioned so as to be inserted into the inner surface of the roof-side frame (102) that constitutes the roof material.

[0027] More specifically, the C-shaped clamping unit (160) includes a C-shaped clamp (162) and a clamping member (164), wherein the clamping member (164) is composed of a clamping screw fastened above the C-shaped clamp (162), and a C-shaped base-side rim frame (131) is further provided on the perimeter of the load-distributing base (130), so that the base-side rim frame (131) is inserted into a roof-side frame (102) provided on the perimeter of the roof material (100), and while the C-shaped clamp (162) is inserted into the base-side rim frame (131), the clamping member (164) in the form of a clamping screw can penetrate from the C-shaped clamp (162) and be connected to the roof-side frame (102) in a screw structure.

[0028] Thus, the organic coupling structure between the C-shaped clamping unit (160), the base-side rim frame (131), and the roof-side frame (102) provides the following specific effects.

[0030] 1. Maintaining the airtightness of roofing materials and fundamentally preventing leaks

[0031] By using the protruding edges of the roof rims for pressure bonding rather than directly perforating the upper surface of the roofing material, it fundamentally eliminates the risk of airtightness failure and leakage associated with conventional perforation methods. In particular, it extends the lifespan of the roof by preventing "worker-induced leakage" that can occur due to concentrated loads during installation and maintenance.

[0033] 2. Maximizing mechanical bonding strength through a multi-layered structure

[0034] A C-shaped base-side rim frame (131) is inserted into the roof-side frame (102), and a C-shaped clamp (162) is inserted into it. Through a 'nested engagement' structure, a sturdy fixing force is secured that remains stable even against external impacts or strong winds. A clamping screw (164) penetrates from the C-shaped clamp (162) to the roof-side frame (102) and is joined by a screw structure, thereby exhibiting shear resistance much stronger than simple pressure.

[0036] 3. Increased ease of installation and maintenance efficiency

[0037] Since the clamping member (164) is fastened to the upper part of the C-shaped clamp (162), the worker can quickly complete the fastening work from the upper part without moving to the lower part of the roof or using complex tools, thereby shortening the construction period. The interlocking structure between the parts guides the frame to be placed in a designated position without a separate precise leveling process, thereby reducing construction errors.

[0039] 4. Optimization of Load Transfer Paths

[0040] The self-weight and working load of the solar power equipment (i.e., solar modules) are directed toward the reinforced end edge (i.e., the direction of the roof-side frame (102)) rather than the vulnerable central part of the roof, thereby preventing deformation and damage to the roofing material.

[0042] At this time, the shock-absorbing pad (120) is further provided with a pad-side edge flange (121) on its perimeter. Since the base-side edge frame (131) of the load-distributing base (130) is fixed to the roof-side frame (102) constituting the roofing material by the C-shaped clamp unit (160), the pad-side edge flange (121) is in close contact with the load-distributing base (130) and the roofing material (100) with a strong adhesive force, thereby having the effect of more effectively enhancing the leak prevention function.

[0043] Meanwhile, in the present invention, the shock absorbing pad (120) has a slope gradient (122) inclined in a specific direction to guide the load toward the main structure of the roof. In addition, the drainage groove (125) formed on the surface of the shock absorbing pad (120) prevents moisture from remaining, thereby blocking corrosion.

[0044] Preferably, as shown in FIG. 7, the drainage groove (125) of the shock-absorbing pad (120) takes on a grid-shaped drainage groove (125) structure.

[0045] Thus, the effect resulting from the drainage groove (125) having the structure of a grid-type drainage groove is as follows.

[0047] 1. Securing Omnidirectional Drainage Paths

[0048] The above grid-shaped drainage groove (125) has horizontal and vertical grooves that are interconnected, thereby ensuring a flow path through which moisture can be discharged by gravity in the shortest path regardless of which direction the main part, the load distribution base (130), the module coupling part (140), and the shock absorption pad (120) are installed on the roofing material.

[0049] 2. Prevention of drainage blockage and detour capability

[0050] The structure of the drainage groove (152) in the grid pattern performs the function of allowing moisture to be bypassed and discharged through adjacent drainage grooves (152) even if a specific grid groove (152) point is closed. This fundamentally prevents corrosion caused by moisture remaining on the surface of the roofing material and the contact area of ​​the shock-absorbing pad (120).

[0051] 3. Inhibition of capillary action and improvement of breathability

[0052] The grid structure effectively prevents moisture adsorption caused by capillary action that may occur at the contact surface between the shock-absorbing pad (120) and the roofing material. By allowing ventilation through the spaces between the grid-arranged drainage grooves (152), the fine moisture remaining after drainage is rapidly dried, thereby further enhancing the corrosion prevention effect of the roofing material.

[0053] 4. Structural adhesion and uniform load distribution

[0054] The grid-arranged drainage grooves (152) maintain uniform rigidity throughout the shock-absorbing pad (120) while flexibly responding to fine irregularities in the roofing material. This evenly distributes the pressure transmitted from the load-distributing base (130) over the entire surface area of ​​the shock-absorbing pad (120), thereby preventing damage to the drainage grooves (152) caused by excessive compression in specific areas.

[0056] Meanwhile, in the present invention, the shock absorbing pad (120) may be configured to have a structure in which two layers having different hardnesses are laminated.

[0057] High hardness upper layer (120HU): Formed with Shore A hardness of 60 to 80 to withstand the self-weight of the module and maintain its shape.

[0058] Low hardness lower layer (120LL): Formed with Shore A hardness of 30 to 50, it adheres to the fine irregularities of the roofing material to ensure airtightness and absorb dynamic walking shock.

[0059] The shock absorbing pad (120), which is a core component of the present invention, adopts a composite layer structure in which layers with different physical properties are stacked rather than a single material, thereby controlling static and dynamic loads in stages.

[0061] 1. High hardness upper layer (120HU)

[0062] The above high-hardness upper layer (120HU) is located on the upper side of the shock-absorbing pad (120) and has a Shore A hardness in the range of 60 to 80.

[0063] The above high-hardness upper layer (120HU) withstands the dead load of the load distribution base (130) and module coupling part (140) placed on the upper part and the entire solar module, and firmly maintains the vertical shape of the solar installation frame of the present invention.

[0064] If the hardness of the above high-hardness upper layer (120HU) is less than 60, the shock-absorbing pad (120) may be permanently deformed due to the long-term self-weight of the solar power facility, and structural instability may occur in which the load-distributing base (130) and the module coupling part (140) tilt to one side.

[0065] If the hardness of the above high-hardness upper layer (120HU) exceeds 80, the flexibility of the material is insufficient, so when external vibration occurs, the shock-absorbing pad (120) cannot absorb it and transmits it directly to the upper structure, such as the load-distributing base (130) and the module joint (140), etc., which has a limitation.

[0066] Meanwhile, the low-hardness lower layer (120LL) is located on the lower side in direct contact with the roofing material (100) and has a relatively soft physical property with a Shore A hardness of 30 to 50.

[0067] The above low-hardness lower layer (120LL) flexibly adheres to fine irregularities or curves on the surface of the roofing material (100) to ensure airtightness and absorbs sudden dynamic shocks that occur when a worker walks.

[0068] If the hardness of the lower layer (120LL) is too soft, with a hardness of less than 30, the shock-absorbing pad (12) is compressed to the limit (Bottom-out) when a worker load occurs, losing its shock-absorbing function and causing a direct impact to the roofing material (100).

[0069] If the hardness of the lower layer (120LL) above exceeds 50, the ability to follow and fill fine gaps between roofing materials (100) (underground panels) or tiles decreases, and the water leakage prevention effect is reduced, such as moisture penetrating into the contact area.

[0070] Accordingly, in the present invention, the laminated structure of the high-hardness upper layer (120HU) and the low-hardness lower layer (120LL) of the shock-absorbing pad (120) divides roles according to the nature of the load. Static module loads are firmly supported by the high-hardness upper layer (120HU) to ensure stability, and dynamic walking impacts of a worker are mitigated by the low-hardness lower layer (120LL), thereby progressively blocking the phenomenon of the connecting parts of the roofing material (100) separating and preventing leakage.
