Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation accessories, and in particular to a novel installation structure for a steel frame. Background Art

[0002] Due to energy shortages, the world has stepped up its efforts to develop and utilize new energy sources, significantly boosting the photovoltaic market. The proliferation of new energy photovoltaic projects worldwide has placed increasing demands on photovoltaic modules. However, traditional aluminum frame modules suffer from significant raw material price fluctuations, high processing energy consumption, low mechanical strength, poor resistance to wind and snow loads, prone to deformation, unsuitable for high-temperature environments, and potential corrosion with steel supports. Steel frames, however, overcome these challenges. Made of zinc-aluminum-magnesium, they offer superior corrosion resistance and load-bearing capacity compared to aluminum frames in extreme environments. Furthermore, they utilize traditional cold-bending technology, a mature technology that reduces production costs and reduces the cost of photovoltaic modules.

[0003] As steel frames become increasingly common, the environments they encounter and the types of brackets they use have also changed significantly, placing greater demands on the installation methods of steel frame components and photovoltaic brackets. This utility model provides a novel steel frame mounting structure to meet the installation requirements of steel frame components in various scenarios, while also improving the pressure-bearing capacity and stability of the steel frame components and photovoltaic brackets. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the utility model provides a new installation structure for a steel frame.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new type of mounting structure for a steel frame includes a steel frame bar and a fixing hardware. The steel frame bar is fixedly mounted on the purlin of a photovoltaic bracket through the fixing hardware. The steel frame bar has three mutually parallel first frame plates, a second frame plate, and a third frame plate. The left and right sides of the second frame plate are respectively arranged on the first connecting longitudinal plate and the second connecting longitudinal plate. The third frame plate is provided with a mounting through hole, and the bottom of the fixing hardware is provided with a mounting groove.

[0007] The fixing hardware includes a horizontal top plate, a vertical rib plate and a horizontal bottom plate, and the vertical rib plate is provided with a bending piece and a stress-bearing piece.

[0008] Preferably, the left and right sides of the second frame plate are respectively arranged on the first connecting longitudinal plate and the second connecting longitudinal plate, the first connecting longitudinal plate extends upward and is connected to the first frame plate, and the second connecting longitudinal plate extends downward and is connected to the third frame plate, so that the cross-section of the steel frame bar is in the shape of an Arabic numeral "5".

[0009] Preferably, the upper and lower ends of the vertical rib are respectively connected to the horizontal top plate and the horizontal bottom plate, so that the cross-section of the fixing hardware is C-shaped and has a concave cavity, and the bending plate and the stress-bearing plate are arranged on the side of the vertical rib facing the concave cavity, and the bending plate is arranged above the stress-bearing plate.

[0010] Preferably, the steel frame bar is completely surrounded by the recessed cavity of the fixing hardware, the first frame plate is arranged close to the lower part of the horizontal top plate, the first connecting longitudinal plate is arranged close to the vertical rib plate, and the third frame plate is arranged close to the upper part of the horizontal bottom plate.

[0011] Preferably, the bending piece is closely arranged below the second frame plate to support the second frame plate, so that when the steel frame bar is subjected to a vertical load, the bending piece provides reverse support for the steel frame bar.

[0012] Preferably, the steel frame bars and fixing hardware are installed on the purlins by means of T-bolts, the screws of the T-bolts pass through the installation holes, the installation grooves and the bolt holes provided on the purlins from top to bottom, and are then tightened by means of nylon anti-loosening flange nuts.

[0013] Preferably, after the steel frame bar is installed on the purlin using a T-shaped bolt, the stress-bearing piece is located above the screw head to press the T-shaped bolt and fit with the screw head, and the bending length of the stress-bearing piece passes through the center point of the screw head.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. After the installation of the fixing hardware of the utility model is completed, the first frame plate supported by the first connecting longitudinal plate is in close contact with the horizontal top plate, and the horizontal top plate presses the first frame plate, so that when the steel frame bar is subjected to back load, the fixing hardware can provide support for the steel frame bar, enhance the ability of the steel frame bar to withstand back load, and thus improve the wind resistance of the steel frame bar.

[0016] 2. The bending piece of the utility model is closely arranged under the second frame plate to support the second frame plate, so that when the steel frame bar is subjected to vertical load, it provides reverse support for the steel frame bar, thereby improving the bearing capacity of the steel frame bar to a certain extent, and enhancing the steel frame bar's anti-deformation ability and pressure bearing capacity, so that the steel frame bar's performance in resisting wind, snow and other loads is improved.

[0017] 3. The present invention uses T-bolts to mount the steel frame strips to the purlins. The screw heads of the T-bolts increase the contact area between the T-bolts and the steel frame strips, increasing the stress-bearing area and improving the stability of the steel frame strips under stress. The stress-bearing plate presses the T-bolts above the screw heads and fits them together. The bending length of the stress-bearing plate passes through the center point of the screw heads, further ensuring the stability of the T-bolt installation and limiting displacement and loosening of the T-bolts after installation. The stress-bearing plate and screw heads work together to cover the installation perforations, while enhancing the pressure-bearing and deformation-resistance capabilities of the steel frame strips, thereby improving the load-bearing capacity and stability of the photovoltaic support.

[0018] 4. The horizontal bottom plate formed by the bent bottom of the fixing hardware of the utility model is placed between the third frame plate and the purlin, which supports the bottom surface of the third frame plate and reinforces the strength of the overlap between the steel frame bar and the purlin, ensuring the stability of the connection between the steel frame bar and the purlin and improving the bearing capacity of the steel frame bar.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-4 A new type of installation structure for a steel frame includes a steel frame bar 1 and a fixing hardware 2. The steel frame bar 1 is fixedly installed on the purlin 300 of the photovoltaic bracket through the fixing hardware 2.

[0027] The steel frame bar 1 has three mutually parallel first frame plates 11, second frame plates 12 and third frame plates 13. The left and right sides of the second frame plate 12 are respectively arranged on the first connecting longitudinal plate 14 and the second connecting longitudinal plate 15. The first connecting longitudinal plate 14 extends upward and is connected to the first frame plate 11, and the second connecting longitudinal plate 15 extends downward and is connected to the third frame plate 13, so that the cross-section of the steel frame bar 1 is in the shape of an Arabic numeral "5".

[0028] The fixing hardware 2 includes a horizontal top plate 21, a vertical rib 22 and a horizontal bottom plate 23. The upper and lower ends of the vertical rib 22 are respectively connected to the horizontal top plate 21 and the horizontal bottom plate 23, so that the cross-section of the fixing hardware 2 is C-shaped and has a concave cavity. The side of the vertical rib 22 facing the concave cavity is provided with a bending piece 24 and a stress-bearing piece 25, and the bending piece 24 is provided above the stress-bearing piece 25.

[0029] When the fixing hardware 2 is installed on the steel frame bar 1, the steel frame bar 1 is completely surrounded by the recessed cavity of the fixing hardware 2, the first frame plate 11 is arranged close to the lower part of the horizontal top plate 21, the first connecting longitudinal plate 14 is arranged close to the vertical rib plate 22, and the third frame plate 13 is arranged close to the upper part of the horizontal bottom plate 23. The horizontal bottom plate 23 is provided with a mounting groove 201, and the third frame plate 13 is provided with a mounting through hole 101.

[0030] When installing the steel frame bar 1, first pass the screw rod 41 of the T-shaped bolt 4 from top to bottom through the installation through-hole 101 and the bolt through-hole provided on the purlin 300, so that the screw head 42 of the T-shaped bolt 4 is above the third frame plate 13. Then move the fixing hardware 2 toward the steel frame bar 1, and insert the horizontal bottom plate 23 between the third frame plate 13 and the purlin 300, so that the screw rod 41 is placed in the installation groove 201. At this time, the stress-bearing piece 25 is above the screw head 42, and the bending piece 24 is below the second frame plate 12. After the fixing hardware 2 is set up, the user uses the nylon anti-loosening flange nut 5 to tighten the T-shaped bolt 4, thereby completing the installation of the fixing hardware 2.

[0031] After the installation of the fixing hardware 2 is completed, the first frame plate 11 supported by the first connecting longitudinal plate 14 is tightly attached to the horizontal top plate 21, and the horizontal top plate 21 presses the first frame plate 11, so that when the steel frame bar 1 is subjected to back load, the fixing hardware 2 can provide support for the steel frame bar 1, thereby enhancing the ability of the steel frame bar 1 to withstand back load, thereby improving the wind resistance of the steel frame bar 1.

[0032] The bending piece 24 is closely arranged below the second frame plate 12 to support the second frame plate 12, so that when the steel frame bar 1 is subjected to a vertical load, it provides reverse support for the steel frame bar 1, thereby improving the bearing capacity of the steel frame bar 1 to a certain extent, and enhancing the steel frame bar 1's anti-deformation ability and pressure bearing capacity, so that the steel frame bar 1's performance in resisting wind, snow and other loads is improved.

[0033] The steel frame bar 1 is installed on the purlin 300 using the T-bolt 4. The screw head 42 of the T-bolt 4 increases the contact area between the T-bolt 4 and the steel frame bar 1, thereby increasing the stress-bearing area and improving the stability of the steel frame bar 1 when subjected to stress. The stress-bearing piece 25 presses the T-bolt 4 above the screw head 42 and fits with the screw head 42. The bending length of the stress-bearing piece 25 passes through the center point of the screw head 42, further ensuring the stability of the installation of the T-bolt 4 and limiting the displacement and loosening of the T-bolt 4 after installation. The stress-bearing piece 25 and the screw head 42 work together to cover the installation through-hole 101, thereby enhancing the pressure-bearing and anti-deformation capabilities of the steel frame bar 1 and improving the load-bearing capacity and stability of the photovoltaic bracket.

[0034] The horizontal bottom plate 23 formed by the bending at the bottom of the fixing hardware 2 is placed between the third frame plate 13 and the purlin 300, supporting the bottom surface of the third frame plate 13, and reinforcing the strength of the overlap between the steel frame bar 1 and the purlin 300, ensuring the stability of the connection between the steel frame bar 1 and the purlin 300, and improving the pressure-bearing capacity of the steel frame bar 1.
