Description

Technical Field

[0001] The utility model relates to the technical field of roof system peripherals, in particular to an anchoring piece and an anchoring base capable of protecting a roof system. Background Art

[0002] Single-layer flexible roofing systems have the characteristics of light weight, good waterproof and thermal insulation performance, fast construction, easy maintenance, and long service life. They are widely used in building roofs such as manufacturing plants, data centers, and transportation hubs. The roofs of such buildings are flat and have a large usable area, making them more suitable for installing photovoltaic power stations. With the release of GB55030 "General Specification for Waterproofing of Buildings and Municipal Engineering" by the Ministry of Housing and Urban-Rural Development, the requirements for waterproof materials, technologies, and performance of roofing systems are constantly increasing. How to choose the photovoltaic power station fixing method that best matches the single-layer flexible roof is a difficult problem that requires careful consideration and careful selection. There are four main types of photovoltaic power station fixing methods currently available on the market:

[0003] The first is the concrete counterweight method. This method is the simplest and most primitive. It is to apply the concrete counterweights originally used on conventional roofs to single-layer flexible roofs as a way to fix the photovoltaic power station. Concrete counterweights are cheap, but they are heavy. In addition, the light steel roof itself is light in weight and is sensitive to loads. If the load redundancy is not high during the design, it is very likely that if you want to use concrete counterweights, you need to reinforce the original roof first, which is a loss of one thing while focusing on another. In addition, due to the soft settlement characteristics of single-layer flexible roofs, the concrete counterweights press on the roof and can easily sink the roof. The subsidence of the roof has a pulling effect on the waterproof membrane, and the settlement of the roof is prone to water accumulation after rainfall. In humid weather, it is easy to breed microorganisms, which affects the life of the membrane.

[0004] The second method is steel column support. This steel column support method must be considered during building design, and the reserved steel columns must be avoided during roof system construction. Steel columns offer high support strength and are firmly fixed to the main building structure. However, since they must be fixed to the main beams, the spacing between the steel columns is large, making them less flexible. This also requires the use of stronger and larger photovoltaic bracket profiles, which in turn increases the cost of the photovoltaic power station. Furthermore, since the steel columns penetrate the roof system structure, waterproofing issues also need to be considered. According to standard requirements, steel columns must use a waterproof coiled tubing with a waterproof height of 250mm, which limits the design height of the photovoltaic power station. Furthermore, the potential for condensation caused by the hot and cold bridge phenomenon of the steel columns must also be considered.

[0005] The third method is gluing or welding. Since gluing or welding is performed only on the membrane, its wind-uplift resistance depends on the membrane's strength. Therefore, the pull-out force generally does not exceed 2.5 kN. Furthermore, gluing or welding is also related to the method of securing the roofing membrane, and can only be used in roofing systems that utilize a fully welded process.

[0006] The fourth method is a dedicated base support. Developed specifically for single-layer flexible roofs, this base can be rooted and fixed to the roof system's bearing layer (corrugated steel sheet), with a designed pull-out force of up to 3.5 kN. This base offers multiple fixing options, and the reserved waterproofing membrane skirt is made of the same brand and material as the roof waterproofing layer, ensuring high compatibility. Welding does not damage the membrane's continuity or lifespan.

[0007] There are many ways to fix the photovoltaic bases for single-layer roofs commonly found on the market. Some are directly welded without penetrating the roof, and some are fixed to the structure through the roof. The fixing methods include screw connection, riveting, flip anchor fixation and other structural forms. Among them, there are also performance differences with the structural fixing methods. For example, the screw connection fixing method has requirements on the thickness of the steel plate of the roof system, and also has requirements on the specifications and number of screws; the riveting fixing method is simple and fast, but considering that the roof system is subjected to the forces of wind pressure pulling and rain and snow pressure for a long time, vibration will occur, and the riveted form will become loose, reducing the firmness. In addition, the tensile bearing capacity of the single-point force mode is limited. In areas with high wind load requirements, the riveted bases are arranged more densely, and the overall cost is higher. For this reason, the applicant designed an auxiliary bracket to improve the auxiliary bracket's ability to resist negative wind pressure and waterproof effect. For details, please refer to the Chinese patent document CN 215176108U. However, this design locks the retaining rod rivet with its open side in contact with the roof during use. This means that when the retaining rod rivet is subjected to upward tension, the stress is primarily concentrated within the thickness support area of ​​the two side walls of the retaining rod rivet. This can easily cause plastic deformation of the side walls of the retaining rod rivet, resulting in changes in the retaining rod rivet's structural performance, shortening its service life, and potentially damaging the roof. Therefore, new innovations are necessary. Utility Model Content

DETAILED DESCRIPTION

[0045] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0046] Example

[0047] This embodiment provides an anchoring base, which includes a fastening base 4 and an anchoring member that can protect the roof system, such as Figures 1 to 3 shown.

[0048] The anchor includes an anchor body 1, a rotating shaft 2 and a connecting rod 3. One side of the anchor body 1 is provided with a plane and a receiving groove, and the receiving groove penetrates one end in the axial direction of the anchor body 1. The rotating shaft 2 is rotatably connected to the anchor body 1, and the axial direction of the rotating shaft 2 is perpendicular to the axial direction of the anchor body 1. The connecting rod 3 is arranged in the receiving groove, one end of the connecting rod 3 is movably connected to the rotating shaft 2, and the other end of the connecting rod 3 extends out of the anchor body 1. In a preferred embodiment, the anchor body 1 preferably includes an anchoring main body 11 and a limiting block 12. The anchoring main body 11 is preferably a long rectangular structure with a "U" - shaped radial cross - section formed by bending a metal plate, which has a top wall 111 and two opposite side walls 112, as Figures 4 to 9 shown. The metal plate is preferably made of stainless steel. The thickness of the metal plate is preferably 2 mm.

[0049] The rotating shaft 2 is located between the two side walls 112, and both ends of the rotating shaft 2 are rotatably connected to the two side walls 112 respectively. The rotating shaft 2 is preferably provided with an adjustment hole, and one end of the connecting rod 3 is movably connected to the rotating shaft 2 through the adjustment hole. Further preferably, the connecting rod 3 is threadedly connected to the adjustment hole. For example, the rotating shaft 2 is preferably a transverse hole nut, and through - holes matching the transverse hole nut are respectively provided on the two side walls 112, and the transverse hole nut is arranged in the through - holes. The connecting rod 3 is preferably a threaded rod, and external threads are provided on all or part of the surface of the connecting rod 3. One end of the connecting rod 3 is in threaded cooperation with the threaded hole of the transverse hole nut, and by driving the relative rotation between the connecting rod 3 and the anchor body 1, the relative position of the anchor body 1 on the connecting rod 3 can be adjusted.

[0050] A notch 113 for the connecting rod 3 to pass through is provided on the top wall 111, and the limiting block 12 restricts the connecting rod 3 from rotating in the direction away from the top wall 111. In a further preferred embodiment, the limiting block 12 is preferably arranged between the two side walls 112, and the limiting block 12 is fixedly connected to the anchoring main body 11. The limiting block 12 is preferably made of metal, such as stainless steel, etc. The limiting block 12 and the anchoring main body 11 are preferably fixed by welding. A groove 121 matching the connecting rod 3 is provided on one side of the limiting block 12 facing the top wall 111, as Figure 4 shown. The groove 121 and the notch 113 on the top wall 111 together form the receiving groove. The connecting rod 3 is arranged in the groove 121. With the above design, the limiting block 12 can not only limit the connecting rod 3 from rotating in the direction away from the top wall 111 in the rotation direction of the connecting rod 3, but also limit the connecting rod 3 in the axial direction of the rotating shaft 2, thereby preventing the connecting rod 3 from shaking in the anchor body 1 and causing the rotating shaft 2 to fall off.

[0051] In a further preferred embodiment, the connecting rod 3 is preferably restricted so that there is always an angle between its axis and the axis of the anchor body 1, that is, when the connecting rod 3 rotates to the position abutting the limit block 12, the connecting rod 3 is tilted toward the top wall 111 at a certain angle, that is, its axis is not parallel to the axis of the anchor body 1, such as Figure 1 and Figure 2 As shown. Further preferably, when the connecting rod 3 abuts the stop block 12, the included angle between the axis of the connecting rod 3 and the axis of the anchor body 1 is 2°-6°, and more preferably 4°. This design makes it easier to rotate the anchor body 1, eliminating the difficulty of rotation caused by the anchor body 1 being parallel to the connecting rod 3.

[0052] In a further embodiment, the limit block 12 is preferably located on one side of the rotating shaft 2, such as Figure 4 and Figure 7 With this design, the limit block 12 can also act as a counterweight, so that the center of gravity of the anchor body 1 is offset toward the end close to the connecting rod 3, thereby enabling the anchor body 1 to rotate quickly and flexibly.

[0053] In a further embodiment, the other end of the anchor body 1 in the axial direction, that is, the end away from the connecting rod 3, is provided with a chamfer 114. Figure 4 It is preferred to provide a large radius fillet at the lower corner of the anchor body 1. On the one hand, this can make it more convenient to install the anchor body 1 on the roof. On the other hand, it can also shift the center of gravity of the anchor body 1 toward the end close to the connecting rod 3, so that the anchor body 1 can rotate more quickly and flexibly.

[0054] The fastening seat 4 is connected to the connecting rod 3, and a mounting hole 41 is provided on the fastening seat 4. Figure 1 or Figure 3As shown, the figure schematically shows a preferred solution, in which the fastening seat 4 is cylindrical. A plane structure is provided on the circumferential surface of the fastening seat 4, so that construction workers can install the fastening seat 4 using conventional tools such as wrenches. Of course, the specific shape of the fastening seat 4 is not limited to cylindrical, and it can also be other shapes, such as prisms. A fixing hole is provided at the bottom end of the fastening seat 4, and the other end of the connecting rod 3 is fixedly connected to the fastening seat 4 through the fixing hole. Preferably, the connecting rod 3 is threadedly connected to the fixing hole. The mounting hole 41 can be used to conveniently install roof peripherals, such as photovoltaic panels, etc. A radially extending fixed support structure 5 is provided on the fastening seat 4. Preferably, a step with a reduced diameter is provided at the bottom of the fastening seat 4, and the fixed support structure 5 is a hollow sheet structure with a folded inner hole edge. The fixed support structure 5 is sleeved on the reduced diameter portion at the bottom of the fastening seat 4 and is fixedly connected to the fastening seat 4. The middle part of the fixed support structure 5 is preferably convex upward, which can effectively enhance the supporting strength of the fixed support structure 5 and meet the installation and placement requirements of the product. The fastening seat 4 and the fixed support structure 5 are preferably made of metal, such as aluminum. The fixed support structure 5 is further preferably a coating plate that can perfectly overlap with the TPO material to ensure the sealing and impermeability between the fixed support structure 5 and the TPO material. Since the coating plate is an existing product, it will not be described in detail here. There are many ways to fix the fixed support structure 5 to the fastening seat 4, such as interference fit or welding fixation, etc. Laser full welding is preferably used to ensure the sealing and impermeability between the fixed support structure 5 and the fastening seat 4. A waterproof membrane 6 is provided on the upper side of the fixed support structure 5, and the waterproof membrane 6 extends to the outside of the fixed support structure 5. The waterproof membrane 6 is preferably made of TPO material. When installed, the fixed support structure 5 will fit tightly against the top of the roof. The waterproof membrane 6 can be welded or bonded to the TPO membrane layer on the roof by hot melting. The strength is much greater than the industry standard, and the waterproof performance and airtightness are also much higher than similar products in the industry. In order to further improve the waterproof performance and sealing performance, a sealing ring 7 can also be sleeved on the fastening seat 4. The sealing ring 7 is preferably a rubber ring, and the sealing ring 7 is located on the side of the fixed support structure 5 away from the connecting rod 3, and further located on the side of the waterproof membrane 6 away from the fixed support structure 5. Specifically, a card slot can be provided on the fastening seat 4, and the sealing ring 7 is clamped in the card slot, and the outwardly extending end of the sealing ring 7 is pressed down on the waterproof membrane 6 below. Since the above structure is a prior art and is not the focus of protection of this application, it will not be described in detail here.

[0055] In a further embodiment, a support column 8 is preferably provided on the connecting rod 3, and the support column 8 is located between the fastening seat 4 and the anchor body 1. Figure 1 and Figure 2 As shown, the support column 8 is sleeved on the connecting rod 3. The support column 8 can be one or more. The support column 8 is preferably made of PE material. In specific implementation, the support column 8 can block the openings on the roof to a certain extent, and the PE material has good chemical stability and mechanical strength, and has high rigidity and toughness. The bearing capacity of the roofing equipment can be transferred to the upper part of the roofing system bearing layer structure through the fasteners and the support column 8, making the force more uniform and stable. At the same time, the PE material also has good heat resistance and cold resistance, which can play a certain role in heat preservation, prevent the rapid loss of heat, and maintain the energy-saving and environmental protection properties of the building roof system. In addition, if the support column 8 adopts a multi-segment structural design, it can match roof insulation layers of different thicknesses, thereby enhancing flexibility and adaptability.

[0056] During implementation, the anchor body 1 is first rotated until it abuts the stopper 12, then inserted through the opening in the roof. Under the influence of natural gravity, the anchor body 1 rotates, with the top wall 111 of the anchor body 1 facing the bottom of the roof. After tightening, the top wall 111 of the anchor body 1 will be tightly pressed against the bottom of the roof installation, and the fixed support structure 5 will be tightly attached to the top of the roof. The waterproof membrane 6 laid on the upper side of the fixed support structure 5 is then heated and welded to the TPO membrane layer of the roof. If necessary, a sealing ring 7 can be installed on the fastening base 4 to improve sealing and waterproofing performance.

[0057] The present application realizes the connection and fixation with the bearing layer (corrugated steel plate) or the main structure of the building (purlin) of the single-layer flexible roof system through an automatically flippable anchor. Because the conventional force-bearing mode includes point, line, and surface force-bearing modes. When the pressure is constant, the larger the force-bearing area, the smaller the pressure, and the smaller the effect of the pressure; when the force-bearing area is constant, the greater the pressure, the greater the pressure, and the greater the effect of the pressure. Therefore, the present application designs the structure of the anchor so that a surface support structure is formed between the anchor body 1 and the roof, which increases the force-bearing area, reduces the force pressure, greatly reduces the effect of the pressure, and can better protect the roof and extend its service life. In addition, the anchor body 1 is less likely to deform, the connection strength between the rotating shaft 2 and the anchor body 1 is stronger, and the performance is more powerful.

[0058] The anchors and anchor bases of this application adopt the concept of integrated prefabricated products, that is, industrialized production and processing are carried out in the factory, and assembly construction processes are carried out on site, which reduces the difficulty of operation and improves construction efficiency. Industrialized production in the factory can ensure product quality and efficient supply, and high integration reduces on-site assembly processes and requirements. On-site only requires drilling holes, installing the base, and welding. The simple construction process not only ensures construction efficiency and quality, but also improves the aesthetics and waterproofness of the construction node parts.

[0059] Example 2: See Figure 10 、 11 As shown, an anchor and anchor base for protecting a roof system are provided. In this embodiment, the anchor is different from the anchor in the first embodiment, but the other structures are the same. The difference between the anchors is that:

[0060] The anchor body 1 includes a limit block 12 and two side walls 112 respectively installed on both sides of the limit block 12, and the accommodating groove 13 is formed between the limit block 12 and the two side walls 112;

[0061] The two ends of the rotating shaft 2 are rotatably connected to the two side walls 112 respectively, and the connecting rod 3 is arranged between the two side walls 112;

[0062] Each side wall 112 is provided with an outwardly extending outer flange 115, which is disposed on the side away from the stop block 12 and forms the plane 14. Taking the illustrated direction as an example, the two side walls are respectively disposed on either side of the top of the stop block, the inner ends of the outer flanges are connected to the top of the corresponding side wall, and the outer flanges are disposed on the outside above the stop block.

[0063] In this embodiment, when the outer flange is not provided, the anchor body forms a U-shaped structure. During use, the anchor body 1 is first rotated until it abuts the stop block 12, and then the anchor body 1 is passed through the opening in the roof. Under the action of natural gravity, the anchor body 1 rotates, and the side wall 111 of the anchor body 1 faces the bottom of the roof. After tightening, the side wall of the anchor body 1 will be tightly pressed against the bottom of the roof installation, and the fixed support structure 5 will be tightly attached to the top of the roof. The waterproof membrane 6 laid on the upper side of the fixed support structure 5 is then heated and welded to the TPO membrane layer of the roof. If necessary, a sealing ring 7 can be installed on the fastening base 4 to improve the sealing and waterproof performance.

[0064] In this method, since the side wall thickness is not set to be particularly thick, the contact area between the anchor body and the roof will be relatively small. In particular, for relatively thin roofs such as color-coated steel plates, the contact point between the anchor body and the roof is easily damaged after being subjected to external forces, resulting in a weak connection. Therefore, in this embodiment, by providing an external flange, the contact area with the roof can be increased, thereby reducing the force per unit area of ​​the roof and making it less prone to damage, thereby ensuring the firmness after installation with the roof and ensuring the installation strength. At the same time, the structure of the anchor body in this embodiment can adopt an integrated stamping structure, which is simpler to manufacture and more cost-effective.

[0065] Example 3: See Figure 12 、 13 As shown, an anchor and anchor base for protecting a roof system are provided. In this embodiment, the anchor is different from the anchor in the first embodiment, but the other structures are the same. The difference between the anchors is that:

[0066] The anchor body 1 includes a limit block 12 and two side walls 112 respectively installed on both sides of the limit block 12, and the accommodating groove 13 is formed between the limit block 12 and the two side walls;

[0067] The two ends of the rotating shaft 2 are rotatably connected to the two side walls 112 respectively, and the connecting rod 3 is arranged between the two side walls 112;

[0068] Each of the side walls 112 is provided with an inwardly extending inner flange 116 , the inner flange 116 being provided on a side away from the limiting block 12 , the inner flange 116 being provided directly opposite the limiting block 12 , and the inner flange 116 forming the plane 14 ;

[0069] The connecting rod 3 is disposed between the inner flanges 116 on both sides, with a slight gap between the connecting rod 3 and the inner end surfaces of the inner flanges 116 on both sides. Taking the illustrated direction as an example, the two side walls are respectively disposed on both sides of the top of the stop block, the outer ends of the inner flanges are connected to the tops of the corresponding side walls, and the inner flanges are located above the stop block.

[0070] In this embodiment, when the outer flange is not provided, the anchor body forms a U-shaped structure. During use, the anchor body 1 is first rotated until it abuts the stop block 12, and then the anchor body 1 is passed through the opening in the roof. Under the action of natural gravity, the anchor body 1 rotates, and the side wall 111 of the anchor body 1 faces the bottom of the roof. After tightening, the side wall of the anchor body 1 will be tightly pressed against the bottom of the roof installation, and the fixed support structure 5 will be tightly attached to the top of the roof. The waterproof membrane 6 laid on the upper side of the fixed support structure 5 is then heated and welded to the TPO membrane layer of the roof. If necessary, a sealing ring 7 can be installed on the fastening base 4 to improve the sealing and waterproof performance.

[0071] In this method, since the side walls are not particularly thick, the contact area between the anchor and the roof is relatively small. This is particularly true for thin roofs such as color-coated steel plates. When subjected to external forces, the contact area between the anchor and the roof can be easily damaged, resulting in a weak connection. Therefore, in this embodiment, an inward flange is provided to increase the contact area with the roof, thereby reducing the force applied per unit area of ​​the roof and making it less susceptible to damage. This ensures secure installation and strength after installation.

[0072] Furthermore, compared to Example 2, this embodiment has a smaller anchoring body. This allows for smaller openings when drilling holes in the roof, thereby reducing damage to the roof and ensuring roof strength. Furthermore, this embodiment utilizes less material and can be integrally formed using a stamping process, resulting in a simpler manufacturing process and lower costs. Furthermore, due to the provision of an inwardly turned flange, the diameter of the connecting rod is slightly smaller than that of the connecting rod in Example 2. This prevents the connecting rod from contacting the inwardly turned flange when rotating relative to the anchoring body, preventing rotational interference.

[0073] As used herein, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0074] In this document, directional terms such as front, back, top, and bottom are defined based on the positions of components in the accompanying drawings and relative to each other, and are intended only for clarity and convenience in describing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0075] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
