Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic support column installation, in particular to a photovoltaic cast-in-place pile column fixing component and a fixing structure. Background Art
[0002] At present, photovoltaic modules are generally installed on fixed steel structure brackets, and fixed steel structure brackets are generally installed on multiple columns. In order to ensure the power generation efficiency of the photovoltaic system, the fixed steel structure bracket needs to be supported by the columns to an appropriate height and ensure that it is oriented as directly as possible to the sunlight. Therefore, the installation accuracy of the lower column is crucial to the power generation performance and reliability of the photovoltaic system. When the verticality, height and other deviations of the lower column are too large, it will cause the upper steel structure bracket to be difficult to level during installation, so that it is impossible to smoothly connect bolts and other equipment or even install components. Even if the installation is barely completed, the overall shape is wavy, which not only fails to meet the aesthetic requirements but also affects the power generation efficiency to a certain extent. More seriously, its unqualified installation quality will cause major safety and quality risks (the internal overall force structure changes).
[0003] Galvanized steel pipe piles are currently the most commonly used photovoltaic columns. However, during the installation of the piles, especially when pouring concrete (grouting) into the piles, the piles are prone to horizontal displacement, tilting or floating, which can easily lead to the piles not meeting the installation requirements. Although there are some fixed tooling brackets in the construction process of the piles, they are time-consuming and labor-intensive to install and disassemble, inconvenient to use, and affect the efficiency of the pile construction.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] The present utility model will be further described below with reference to the drawings and embodiments.
[0028] Such as Figures 1 to 3As shown in the figure, a fixing component for a photovoltaic cast-in-place pile column of the present utility model includes a left limiting bracket 2, a right limiting bracket 3, and a pin 1 that is matched with a radial through hole provided at the upper end of the cast-in-place pile 5 and can be inserted into the through hole and has a length greater than the diameter of the cast-in-place pile 5. Both the left limiting bracket 2 and the right limiting bracket 3 include a support platform 21, a left support rod 22 and a right support rod 23 that are inclined upward. The support platform 21 is mainly used to make full contact with the foundation surface for the purpose of facilitating the fixation of the corresponding limiting bracket. The lower ends of the left support rod 22 and the right support rod 23 are respectively fixedly connected to the corresponding support platform 21. The left support rod 22 and the right support rod 23 of the left limiting bracket 2 are arranged side by side and parallel, and there is a spacing between the left support rod 22 and the right support rod 23 of the left limiting bracket 2 to form a first limiting cavity 25 adapted to the diameter of the cast-in-place pile 5. The left support rod 22 and the right support rod 23 of the right limiting bracket 3 are also arranged side by side and parallel, and there is a spacing between the left support rod 22 and the right support rod 23 of the right limiting bracket 3 to form a second limiting cavity 26 that can clamp the left support rod 22 and the right support rod 23 of the left limiting bracket 2 therein.
[0029] The inclination angles of the left support rod 22 and the right support rod 23 are generally 30° - 60°. In the embodiment of the present utility model, the inclination angles of the left support rod 22 and the right support rod 23 are 45°. The through hole on the cast-in-place pile that is matched with the pin is generally provided on the cast-in-place pile by means of reservation.
[0030] The specific use process of the fixing component for the photovoltaic cast-in-place pile column of the present utility model is as follows Figures 4 to 6As shown in the figure. When the cast-in-place pile 5 is driven into the foundation 6 until the elevation of the upper end of the cast-in-place pile 5 reaches the required position, first insert the bolt 1 into the radial through hole at the upper end of the cast-in-place pile 5, and both ends extend out of the through hole; then clamp the left support rod 22 and the right support rod 23 of the left limit support 2 on both sides of the cast-in-place pile 5, and press them on one side of both ends of the bolt 1 respectively; then press the left support rod 22 and the right support rod 23 of the right limit support 3 on the other side of both ends of the bolt 1 respectively, and clamp the left support rod 22 and the right support rod 23 of the left limit support 2 inside to form a cross, thereby forming a V-shaped limit structure that clamps the bolt 1 inside; finally, set a counterweight 4 on the support platforms 21 of the left limit support 2 and the right limit support 3, and fix the support platforms 21 on the foundation to prevent the left limit support 2 and the right limit support 3 from moving and rotating. In this way, the left support rods 22 and the right support rods 23 of the two limit supports not only clamp the upper end of the cast-in-place pile, but also position the bolt in the V-shaped limit structure, which can not only prevent the cast-in-place pile 5 from having horizontal displacement and skew during installation and grouting, but also prevent it from floating, ensuring the position accuracy of the cast-in-place pile. In addition, the above fixing components can be connected and fixed together without setting connecting parts. During installation, only need to move the left limit support 2 and the right limit support 3 from both sides of the cast-in-place pile towards the approaching direction, and during disassembly, only need to move the left limit support 2 and the right limit support 3 towards the separating direction, and its installation and disassembly are convenient.
[0031] In actual construction, affected by terrain and different installation requirements, etc., the distances between the bolts on different cast-in-place piles and the ground will be different after the cast-in-place piles are inserted into the foundation in place. The fixing component of the present utility model has a left support rod 22 and a right support rod 23 which are inclined upwards on the stable support platform of the limit support. During use, the distance between the support platform 21 of the limit support and the pipe pile can be adjusted by moving the limit support, so that the support rods can be in contact and cooperation with bolts at different heights, thus meeting the requirements of contact and cooperation limit with bolts at different heights. Its applicability is good and the structure is also simple.
[0032] In the present utility model, the counterweight 4 can be a counterweight block or a person, that is, a person stands on the stable support platform to form a counterweight.
[0033] The support platform 21 can be a plate-like structure. In the embodiment of the present utility model, the support platform 21 is a square frame structure formed by welding four rods. In the case of the same coverage area, the stable support platform of this structure is lighter in weight and more convenient for handling and moving.
[0034] The left support rod 22 and the right support rod 23 can be directly fixedly connected to the corresponding support platform 21 by means of welding, bolt connection, etc. Such as Figure 2 and Figure 3As shown, in the embodiment of the present utility model, sliders 27 for adjusting the distance between the left support rod 22 and the right support rod 23 are provided on the support platform 21. A fixing mechanism 24 for locking the position of the slider 27 is provided on the slider 27. The lower end of the left support rod 22 or the right support rod 23 is fixedly connected to the slider 27 on the corresponding support platform. In this way, by moving the slider, the support rod connected thereto can be moved, so that it moves in a direction closer to or farther from the other support rod, thereby adjusting the distance between the corresponding left support rod 22 and the right support rod 23, and thus being applicable to the fixation of cast-in-place piles with different outer diameters. When the slider 27 is adjusted in place, the slider 27 can be locked and fixed on the corresponding support platform 21 through the fixing mechanism 24 to fix the corresponding support rod.
[0035] The fixing mechanism 24 can adopt a bolt, a locking screw, etc. In the present utility model, the fixing mechanism 24 is a locking screw provided on the slider 27. When it is necessary to lock the slider, the locking screw is screwed, so that the other end of the locking screw cooperates with the corresponding stable support platform, such as: a pressing fit, to lock and fix the slider.
[0036] The present utility model also provides a fixing structure for a photovoltaic cast-in-place pile column. This fixing structure adopts the above-mentioned fixing assembly for a photovoltaic cast-in-place pile column. The bolt 1 is inserted into the radial through hole at the upper end of the cast-in-place pile 5, and both ends extend out of the through hole; the left limiting bracket 2 is clamped on both sides of the cast-in-place pile 5 through its left support rod 22 and right support rod 23. The left support rod 22 and the right support rod 23 of the left limiting bracket 2 are respectively pressed on one side of both ends of the bolt 1; the right limiting bracket 3 is arranged to clamp the left support rod 22 and the right support rod 23 of the left limiting bracket 2 through its left support rod 22 and right support rod 23. The left support rod 22 and the right support rod 23 of the right limiting bracket 3 are respectively pressed on the other side of both ends of the bolt 1, thereby forming a V-shaped limiting structure for clamping the bolt 1 therein; the left limiting bracket 2 and the right limiting bracket 3 are respectively supported on the foundation 6 on both sides of the cast-in-place pile 5 through their support platforms 21, and a counterweight 4 for fixing the support platform 21 is provided on the support platform 21.
[0037] The above-mentioned fixing structure can prevent the cast-in-place pile 5 from experiencing horizontal displacement and skew during the installation of grouting through the left support rod 22 and the right support rod 23 of the two limiting brackets, and can also prevent it from floating upward, ensuring the position accuracy of the cast-in-place pile. Moreover, the fixing components are not connected and fixed together through connecting pieces. During installation, it only needs to move the left limiting bracket 2 and the right limiting bracket 3 from both sides of the cast-in-place pile towards the direction of approaching each other, while during disassembly, it only needs to move the left limiting bracket 2 and the right limiting bracket 3 in the direction of moving away from each other, and its installation and disassembly are convenient. In addition, on the stable support platform of the limiting bracket of the fixing component, there are left support rod 22 and right support rod 23 arranged obliquely upward. During the use process, the distance between the support platform 21 of the limiting bracket and the pipe pile can be adjusted by moving the limiting bracket, so that the support rod can be in contact and cooperation with pins at different heights, thus meeting the requirements of contact and cooperation limiting with pins at different heights, and its applicability is good.
