Description

Technical Field

[0001] This utility model is a rooftop photovoltaic installation structure, belonging to the field of photovoltaic installation. Background Technology

[0002] The rooftop photovoltaic (PV) installation structure is a crucial component for ensuring the safe and efficient operation of a PV system. PV panels need to be installed on the roof at an angle using brackets. Multiple concrete platforms are poured on the roof, and during the pouring process, several bolts are pre-embedded in the upper part of these platforms. The PV brackets are then installed on the concrete platforms using nuts that engage with the bolts. Finally, the PV panels are installed onto the brackets, completing the rooftop PV installation. However, this method of pre-embedding bolts in the concrete platforms is prone to tilting due to construction errors. This can cause the bolts to misalign with the holes at the bottom of the PV brackets, and the bolts embedded in the concrete platforms cannot be adjusted in position, hindering the smooth installation of the PV brackets. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof photovoltaic installation structure to solve the problems mentioned in the background technology. This utility model enables the connection structure that restricts the position of the photovoltaic bracket to form an assembly relationship with the concrete platform, which facilitates the smooth installation of the photovoltaic bracket.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rooftop photovoltaic installation structure, comprising a photovoltaic panel, two sets of crossbeams mounted on the lower surface of the photovoltaic panel, with inclined connecting beams mounted at both ends of the crossbeams, legs mounted on the upper ends of the connecting beams, and concrete platforms for fixing to the roof provided on the lower ends of the legs and the lower sides of the connecting beams away from the legs. Two right-angle irons are bolted to the lower ends of the legs and the lower sides of the connecting beams away from the legs. A pad is provided on the upper end of the concrete platform, and the right-angle irons are connected to the pad by fasteners formed by square-head screws and first nuts. Ear plates are mounted on both ends of the pad, and a horizontal hole is opened on the upper end of the concrete platform. A circular hole is opened on one side of the ear plate, concentric with the horizontal hole. A stud is inserted into the horizontal hole, and the end of the stud passes through the circular hole. A second nut is threaded to both ends of the stud.

[0005] Furthermore, the lower surface of the pad is recessed upward to form multiple square grooves, and a vertical hole is provided at the top of the square groove. The head of the square-head screw is inserted into the square groove, and the shank of the square-head screw passes through the vertical hole and the hole on the right-angle iron and is threaded to the first nut.

[0006] Furthermore, a plurality of ribs are installed on the upper surface of the pad, and the ribs are in contact with the horizontal part of the right angle iron.

[0007] Furthermore, the upper part of the two parallel sides of the concrete platform is recessed to form a notch, and the notch communicates with the transverse hole.

[0008] Furthermore, a base is installed at the lower end of the concrete platform, and the base and the concrete platform are integrally formed.

[0009] Furthermore, a reinforcing bar is bolted between the two right-angle irons at the lower end of the support leg, and the end of the reinforcing bar away from the right-angle irons is bolted to the middle position of the connecting beam.

[0010] Furthermore, the ear plate and the pad are integrally formed structures, and the ear plate and the pad are arranged perpendicular to each other.

[0011] The beneficial effects of this utility model are:

[0012] 1. Install a pad on the top of the concrete platform and insert square-headed screws into the space formed by the square slot and vertical hole. After the square-headed screws pass through the vertical hole and the hole on the right-angle iron, tighten the first nut to complete the assembly of the photovoltaic bracket formed by the pad, support legs, right-angle iron, connecting beam and crossbeam. After the studs pass through the channel formed by the horizontal hole and the round hole, tighten the two second nuts to complete the assembly of the pad and the concrete platform. Compared with the method of pre-embedding screws on the concrete platform, there will be no screw tilting. The connection structure that restricts the position of the photovoltaic bracket is assembled with the concrete platform, which facilitates the smooth installation of the photovoltaic bracket.

[0013] 2. Make a notch in the concrete platform that communicates with the horizontal hole. When the second nut and the stud cannot be separated normally due to corrosion, which affects the replacement of the photovoltaic bracket, use the space inside the notch to cut off the stud, so as to separate the pad without damaging the concrete platform.

[0014] 3. When using the square-head screw and the first nut to connect the washer and the right-angle iron, the horizontal part of the right-angle iron and the washer are separated by the support of the rib. When the second nut and the square-head screw cannot be separated normally due to corrosion, the square-head screw can be cut off by using the gap between the right-angle iron and the washer, which makes it easy to replace the corroded square-head screw.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a rooftop photovoltaic installation structure, including a photovoltaic panel 1, two sets of crossbeams 2 installed on the lower surface of the photovoltaic panel 1, and inclined connecting beams 3 installed at both ends of the crossbeams 2. Support legs 4 are installed on the upper end of the connecting beams 3. The support legs 4, crossbeams 2, and connecting beams 3 together form a photovoltaic support. The lower end of the support legs 4 and the lower side of the connecting beams 3 away from the support legs 4 are provided with concrete platforms 6 for fixing to the roof. The lower end of the concrete platform 6 is equipped with a base 7, which is integrally formed with the concrete platform 6. The base 7 increases the connection area between the concrete platform 6 and the roof. The lower end of the support legs 4 and the lower end of the connecting beams 3 away from the support legs 4 are each bolted with two right-angle irons 16. A reinforcing rod 5 is bolted between the two right-angle irons 16 at the lower end of the support legs 4. The end of the reinforcing rod 5 away from the right-angle irons 16 is bolted to the middle position of the connecting beams 3. The design of the reinforcing rod 5 improves the stability of the structure.

[0024] See Figures 1-5A pad 13 is provided on the upper end of the concrete platform 6. A right-angle iron 16 is connected to the pad 13 by a fastener formed by a square-head screw 12 and a first nut 11. Both ends of the pad 13 are equipped with ear plates 8, which are integrally formed with the pad 13. The ear plates 8 and the pad 13 are arranged perpendicularly to each other. A horizontal hole 20 is opened at the upper end of the concrete platform 6. A circular hole 18 is opened on one side of the ear plate 8, which is concentric with the horizontal hole 20. A stud 9 is inserted into the horizontal hole 20, and the end of the stud 9 passes through the circular hole 18. Both ends of the stud 9 are threaded with a second nut 10. The pad 13 is installed on the upper end of the concrete platform 6, and the square-head screw 12 is inserted into the hole 10. Within the space formed by the square groove 19 and the vertical hole 17, the square-headed screw 12 passes through the holes in the vertical hole 17 and the right-angle iron 16, and then the first nut 11 is screwed on to complete the assembly of the photovoltaic bracket formed by the pad 13, the support leg 4, the right-angle iron 16, the connecting beam 3, and the crossbeam 2. After the stud 9 passes through the channel formed by the horizontal hole 20 and the round hole 18, two second nuts 10 are screwed on to complete the assembly of the pad 13 and the concrete platform 6. Compared with the method of pre-embedding the screws on the concrete platform 6, there will be no tilting of the screws. This allows the connecting structure that restricts the position of the photovoltaic bracket to form an assembly relationship with the concrete platform 6, which facilitates the smooth installation of the photovoltaic bracket.

[0025] See Figures 2-4 The lower surface of the pad 13 is recessed upward to form multiple square grooves 19. A vertical hole 17 is opened at the top of the square groove 19. The head of the square head screw 12 is inserted into the square groove 19. The shank of the square head screw 12 passes through the vertical hole 17 and the hole on the right angle iron 16 and is threaded to the first nut 11. Multiple ribs 14 are installed on the upper surface of the pad 13. The ribs 14 are in contact with the horizontal part of the right angle iron 16. When the pad 13 and the right angle iron 16 are connected by the square head screw 12 and the first nut 11, a gap is created between the horizontal part of the right angle iron 16 and the pad 13 under the support of the ribs 14. When the second nut 10 and the square head screw 12 cannot be properly separated due to corrosion, the square head screw 12 can be cut off by the gap between the right angle iron 16 and the pad 13, which makes it easy to replace the corroded square head screw 12.

[0026] See Figure 2 and Figure 5 The upper part of the two parallel sides of the concrete platform 6 is recessed to form a notch 15, which is connected to the horizontal hole 20. The notch 15 is opened on the concrete platform 6 to connect with the horizontal hole 20. When the second nut 10 and the stud 9 cannot be separated normally due to corrosion, which affects the replacement of the photovoltaic bracket, the internal space of the notch 15 is used to cut off the stud 9, so that the pad 13 can be separated without damaging the concrete platform 6.
