Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket support, in particular to an anchor cable structure at the end of a flexible bracket. Background Art

[0002] Photovoltaic flexible bracket technology is achieved by installing cables between the tops of multiple columns and setting multiple groups of photovoltaic panels on the cables. The cables and photovoltaic panels are concentratedly pulled at the ends of the columns, making the columns prone to tilting, especially when the photovoltaic brackets are installed in areas with larger spans, such as rivers, mountains, etc., and under the influence of wind and rain, the pulling effect on the columns is more intense. When the columns tilt, the posture of the photovoltaic panels will also change accordingly, thereby reducing the working efficiency of the photovoltaic panels.

[0003] Therefore, it is necessary to diagonally anchor the ends of the flexible bracket to increase the tensile strength of the column. The traditional diagonal anchor cable structure is to pre-embed the anchor bolts and connecting plates at the top of the cast-in-place pile, and then connect the end anchor cable to the anchor bolt to form a reverse pulling anchor cable structure for the end of the flexible bracket, providing lateral and longitudinal reaction forces for the end of the flexible bracket to resist the pulling force of the cable and photovoltaic panel, and ensure the stability of the entire flexible bracket. However, this traditional diagonal anchor cable structure has problems such as cracking of the concrete at the top of the cast-in-place pile, bending of the anchor bolts, cracking of the welds between the anchor bolts and the connecting plate, and decoupling of the connection due to excessive force at the connection. In addition, if the reverse pulling force at the end of the flexible bracket is to be increased, the cast-in-place pile needs to be extended, which increases the construction period and cost of the cast-in-place pile.

[0004] In response to the above problems, this application summarizes and proposes a new flexible bracket end anchor cable structure based on the design and construction characteristics of the flexible bracket. Utility Model Content

[0005] The utility model provides an anchor cable structure at the end of a flexible bracket.

[0014] (2) The anchor cable structure is equipped with a funnel casing and a reinforced steel cage at the top of the end anchor pile, which can prevent the end anchor cable from cracking the concrete on the top of the end anchor pile and prevent the end anchor cable from directly contacting the concrete and causing wear.

[0023] like Figures 1 to 3 As shown, a flexible support end anchor cable structure includes an end anchor pile 1, an end pile 2, and a ground beam 3. The bottom end of the end pile 2 is fixed to the end pile foundation 11, and the top end of the end pile 2 is connected to the end anchor cable 9. The bottom end of the end anchor cable 9 extends into the end anchor pile 1 and passes through the end anchor pile steel cage 4 and the spacer 6 set in the end anchor pile 1 in sequence. It is then fixed to the bottom of the end anchor pile steel cage 4 by the anchor 5, and the spacer 6 is clamped between the end anchor pile steel cage 4 and the anchor 5. This anchor cable structure changes the anchoring position of the end anchor cable 9 of the flexible support from the traditional top fixation of the end anchor pile 1 to the bottom fixation of the end anchor pile 1. The rear end anchor cable 9 and the end anchor pile 1 are cast to form a whole. The entire end anchor pile 1 provides tension for the end anchor cable 9, which can effectively solve the problems of the weak connection between the end anchor cable 9 and the end anchor pile 1, insufficient tensile strength, and other problems existing in traditional anchor cable structures.

[0024] like Figure 2As shown, a funnel sleeve 8 is further provided inside the top of the end anchor pile reinforcement cage 4, which surrounds the outer periphery of the end anchor cable 9. A reinforcing steel cage 7 surrounds the outer periphery of the funnel sleeve 8, which is disposed within the end anchor pile reinforcement cage 4. By providing the funnel sleeve 8 at the top of the end anchor pile 1, this anchor cable structure prevents the end anchor cable 9 from pulling and cracking the concrete at the top of the end anchor pile 1, and also prevents wear and tear caused by direct contact between the end anchor cable 9 and the concrete. Furthermore, by providing the reinforcing steel cage 7 around the funnel sleeve 8, the tensile crack resistance of the concrete at the top of the end anchor pile 1 is further enhanced.

[0025] A foundation reinforcement cage 12 is provided within the end pile foundation 11. A ground beam reinforcement cage 10 is provided within the ground beam 3. One end of the ground beam reinforcement cage 12 is connected to the end anchor pile reinforcement cage 4, and the other end is connected to the foundation reinforcement cage 12. This anchor cable structure, by placing the ground beam 3 between the end anchor pile 1 and the end pile foundation 11, and connecting the ground beam reinforcement cage 10 within the ground beam 3 between the end anchor pile reinforcement cage 4 and the foundation reinforcement cage 12, forms a single unit after pouring concrete. This structure can disperse the tensile force acting on the end anchor cable 9 and the end anchor pile 1, optimize the force distribution of the end anchor pile 1, shorten the length of the end anchor pile 1, and thereby reduce the construction period and cost of the end anchor pile 1.

[0026] The end anchor pile reinforcement cage 4 , the foundation reinforcement cage 12 and / or the reinforcement reinforcement cage 7 all include a plurality of vertical reinforcements and spiral reinforcements spirally arranged inside each vertical reinforcement, which is beneficial to enhancing the tensile strength of the end anchor pile 1 and the end pile foundation 11 .

[0027] During construction, after the end anchor pile reinforcement cage 4 is completed, the pad 6 is welded to its bottom, the reinforcing steel cage 7 is tied inside the end anchor pile reinforcement cage 4, and then the funnel sleeve 8 is inserted into the reinforcing steel cage 7, and the opening of the funnel sleeve 8 is welded or tied to the top of the end anchor pile reinforcement cage 4.

[0028] Then, one end of the end anchor cable 9 is passed through the funnel casing 8, the end anchor pile reinforcement cage 4 and the spacer 6, and the end anchor cable 9 is fixed to the bottom of the end anchor pile reinforcement cage 4 using the finished anchor 5. The assembled end anchor pile reinforcement cage 4 is then placed into the end anchor pile 1.

[0029] Place the prepared foundation reinforcement cage 12 and ground beam reinforcement cage 10 into the end pile foundation 11 and ground beam 3, and tie the two ends of the ground beam reinforcement cage 10 to the end anchor pile reinforcement cage 4 and foundation reinforcement cage 12. After completion, pour concrete to cast the end anchor pile 1, ground beam 3, and end pile foundation 2 into one piece.

[0030] Then install the end pile 2 on the end pile foundation 11, tighten the end anchor cable 9 and connect its other end to the top of the end pile 2. At this point, the anchor cable fixation of the end of the photovoltaic flexible support is completed.

[0031] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
