Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and in particular to a flat roof ballast support. Background Technology

[0002] Foundation securing is a crucial step in the installation of flat-roof photovoltaic systems. Traditionally, precast or cast-in-place concrete single-base (or strip-base) structures are used as the foundation for the flat-roof ballast support system, or expansion bolts or chemical anchors are used for fixing. However, these methods have revealed numerous drawbacks and risks in practical applications.

[0003] While precast concrete foundations are relatively easy to construct, their counterweight is often insufficient, requiring a large number of foundations, resulting in excessive weight that challenges the roof's load-bearing capacity and is also costly. On-site cast-in-place concrete foundations, on the other hand, require the fabrication of concrete molds, have a long construction period, are more difficult, and have relatively high labor costs.

[0004] On the other hand, while using expansion bolts or chemical bolts to fix the system simplifies the construction process to some extent, it carries the risk of penetrating the floor slab and damaging the original roof layer, which can lead to problems such as water leakage and seepage later on, threatening the stability and safety of the photovoltaic system. To address these issues, we provide a flat roof ballast bracket. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1 — Figure 5 The example shown.

[0034] This application provides a flat roof ballast support, which is installed on an installation surface (not shown in the figure). The flat roof ballast support includes at least two parallel load-bearing members 100, a connecting adhesive 200, an installation frame 300, and a photovoltaic panel 400.

[0035] In some embodiments, the adhesive 200 is disposed on the bottom surface of the support member 100, the support member 100 is fixedly connected to the mounting surface through the adhesive 200, the mounting bracket 300 is fixedly mounted on the support member 100, and the photovoltaic panel 400 is detachably and fixedly mounted on the mounting bracket 300.

[0036] See Figure 1 As shown, during installation, the installation surface must first be cleaned, then the connecting adhesive 200 is applied to the corresponding position on the installation surface, then the carrier 100 is placed on the connecting adhesive 200, and the mounting frame 300 is fixed on the carrier 100. Next, the photovoltaic panel 400 is installed on the mounting frame 300, thus completing the installation of the photovoltaic panel 400.

[0037] In this embodiment, since the support member 100 is directly bonded to the mounting surface by the connecting adhesive 200, there is no need to drill holes or use expansion bolts. This prevents the roof from being punctured and leaking water, and also reduces the weight of the overall support and the construction period, thereby reducing installation costs.

[0038] Furthermore, the adhesive 200 is a strong adhesive structural adhesive. Specifically, the adhesive 200 can be a silicone structural adhesive. In practice, different types of structural adhesives can be selected as needed, and there is no specific limitation.

[0039] Each of the aforementioned support members 100 is provided with a counterweight 500.

[0040] Please continue reading. Figure 1As shown, in order to improve overall stability, a counterweight 500 is provided on the bearing 100. The counterweight 500 improves stability, prevents the bearing 100 and the mounting bracket 300 from moving due to excessive wind force, and also reduces the load on the connecting adhesive 200 on the horizontal plane, thereby increasing service life.

[0041] In this embodiment, concrete is inexpensive and easy to produce because the counterweight 500 can be made of concrete blocks.

[0042] The support member 100 includes a first support structure 110 and a second support structure 120. The first support structure 110 and the second support structure 120 are arranged parallel to each other, and the bottom surface of the first support structure 110 and the second support structure 120 are provided with connecting adhesive 200.

[0043] Please see Figure 2 As shown, each support member 100 is composed of a first support structure 110 and a second support structure 120 arranged in parallel with each other. The bottom surfaces of the first support structure 110 and the second support structure 120 are connected to the mounting surface by a connecting adhesive 200. A counterweight 500 is placed on the surface formed by the first support structure 110 and the second support structure 120. That is, the two sides of the counterweight 500 in the width direction are limited by the first support structure 110 and the second support structure 120 to prevent the counterweight 500 from separating from the first support structure 110 and the second support structure 120.

[0044] The bottom surfaces of the first carrier structure 110 and the second carrier structure 120 both have recessed and / or raised patterns (not shown in the figure).

[0045] In this embodiment, since the first carrier structure 110 and the second carrier structure 120 are usually aluminum alloy profiles with smooth surfaces, in order to improve the adhesion between the first carrier structure 110 and the second carrier structure 120 and the adhesive 200, the surfaces of the first carrier structure 110 and the second carrier structure 120 that contact the adhesive 200 are textured, thereby increasing the roughness of the first carrier structure 110 and the second carrier structure 120 and improving the bonding force with the adhesive 200.

[0046] It is understood that the shape of the pattern and whether it is raised or recessed are not limited. For example, the pattern can be a horizontal and vertical line with concave or raised sections, or other shapes. In this embodiment, in order to reduce production costs, steel wool is used to scratch the bottom surfaces of the first carrier structure 110 and the second carrier structure 120 to increase the roughness in turn.

[0047] The first carrier structure 110 includes a first carrier plate 111, a second carrier plate 112 is provided on the side of the first carrier plate 111 facing the second carrier structure 120, the second carrier structure 120 includes a third carrier plate 121, and a fourth carrier plate 122 is provided on the side of the third carrier plate 121 facing the first carrier structure 110; the counterweight 500 is provided on the surface formed by the second carrier plate 112 and the fourth carrier plate 122.

[0048] Please see Figure 2 As shown, in order to place the counterweight 500 without affecting the installation of the mounting bracket 300, the first carrier structure 110 is composed of a first carrier plate 111 and a second carrier plate 112. In the height direction, the first carrier plate 111 is higher than the second carrier plate 112. Similarly, the second carrier structure 120 is composed of a third carrier plate 121 and a fourth carrier plate 122. In the height direction, the third carrier plate 121 is higher than the fourth carrier plate 122. The first carrier plate 111 and the third carrier plate 121 are at the same height, and the second carrier plate 112 and the fourth carrier plate 122 are at the same height. The second carrier plate 112 and the fourth carrier plate 122 are located on the side close to each other.

[0049] Specifically, the first carrier plate 111 and the third carrier plate 121 have the same height, H1, and the second carrier plate 112 and the fourth carrier plate 122 have the same height, H2, satisfying that H1 > H2.

[0050] Understandably, the plane formed by the second carrier plate 112 and the fourth carrier plate 122 is used to place the counterweight 500. The counterweight 500 is blocked on both sides in the width direction by the first carrier plate 111 and the third carrier plate 121 to limit the position of the counterweight 500. Furthermore, the first carrier plate 111 and the third carrier plate 121 can abut against the counterweight 500 to prevent the counterweight 500 from moving. The surface formed by the upper surface of the first carrier plate 111 and the upper surface of the third carrier plate 121 is used to place and install the mounting bracket 300.

[0051] The first carrier plate 111 and the second carrier plate 112 are integrally formed and both are hollow, and the third carrier plate 121 and the fourth carrier plate 122 are integrally formed and both are hollow.

[0052] Please continue reading. Figure 1 and Figure 2 As shown, the first carrier plate 111 and the second carrier plate 112 are integrally formed and hollow, and the third carrier plate 121 and the fourth carrier plate 122 are integrally formed and hollow, which can reduce production costs. Specifically, the first carrier plate 111, the second carrier plate 112, the third carrier plate 121 and the fourth carrier plate 122 can be aluminum profiles. Aluminum profiles have the advantages of being lightweight, high-strength and easy to cut and install, which facilitates handling and installation.

[0053] See Figure 1 and Figure 5 As shown, multiple mounting brackets 300 are fixedly installed on the support member 100 to install the photovoltaic panel 400. Specifically, the mounting bracket 300 includes a base rod 310 fixedly connected to the support member 100. A connecting rod 320 is fixedly installed at one end of the base rod 310. A support rod 330 is provided between the end of the connecting rod 320 away from the base rod 310 and the other end of the base rod 310. The support rod 330 is used for the fixed installation of the photovoltaic panel 400.

[0054] The mounting frame 300 is provided with a plurality of pressing and fixing components 600. The photovoltaic panel 400 is detachably connected to the mounting frame 300 through the pressing and fixing components 600. The pressing and fixing components 600 include abutment plates 610, one end of which abuts against the photovoltaic panel 400. Fasteners 620 are provided on the abutment plates 610, and the abutment plates 610 are fixedly connected to the mounting frame 300 through the fasteners 620.

[0055] See Figure 3 As shown, in order to facilitate the installation and fixing of the photovoltaic panel 400, the photovoltaic panel 400 is fixedly installed on the mounting frame 300 by the cooperation of multiple abutment plates 610 and fasteners 620. Specifically, the abutment plates 610 are installed on the mounting frame 300 by fasteners 620. One end of the abutment plate 610 presses down on the edge of the photovoltaic panel 400. During the tightening of the fasteners 620, the abutment plate 610 moves downward continuously, thereby continuously increasing the downward pressure on the photovoltaic panel 400, thus fixing the photovoltaic panel 400.

[0056] The fastener 620 includes a first connecting plate 611, one end of which is provided with a first pressure plate 612. The bottom surface of the first pressure plate 612 presses down against the photovoltaic panel 400. The end of the first connecting plate 611 away from the first pressure plate 612 is provided with a second connecting plate 613. The second connecting plate 613 is arranged parallel to the first pressure plate 612, and a mounting hole 614 is provided through the second connecting plate 613.

[0057] See Figure 3 and Figure 4As shown, firstly, the end of the first pressure plate 612 away from the first connecting plate 611 abuts against the edge of the photovoltaic panel 400, thereby pressing down on the photovoltaic panel 400. Then, the fastener 620 passes through the mounting hole 614 to the mounting bracket 300, thereby fixing the second connecting plate 613 to the mounting bracket 300. When the fastener 620 is tightened, the end of the second pressure plate 615 away from the second connecting plate 613 abuts against and presses down on the mounting bracket 300. As the fastener 620 continues to tighten, the force exerted by the first pressure plate 612 on the photovoltaic panel 400 increases, and similarly, the force exerted by the second pressure plate 615 on the mounting bracket 300 also increases. At this time, the second connecting plate 613 is in a suspended state. As the fastener 620 continues to tighten, the second connecting plate 613 will undergo a certain deformation.

[0058] In this embodiment, the fastener 620 is a bolt. Specifically, the fastener 620 passes through the mounting hole 614 and is connected to the support rod 330.

[0059] The working process of this utility model is as follows: First, clean the dust on the mounting surface. Then, scratch the bottom surface of the support 100 to increase its roughness. Next, apply connecting adhesive 200 at a predetermined position on the mounting surface. Place the support 100 on the connecting adhesive 200, thereby connecting the support 100 to the mounting surface through the connecting adhesive 200. To make the entire bracket more stable, a counterweight block 500 can be placed on the support 100 for counterweighting. Install the mounting frame 300 on the support 100, and place the photovoltaic panel 400 on the mounting frame 300. Fix the photovoltaic panel 400 to the mounting frame 300 by the pressing and fixing component 600 to prevent the photovoltaic panel 400 from moving.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
