Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic flexible support connection technology, specifically relating to a component for connecting flexible photovoltaic supports. Background Technology

[0002] Currently, depending on the structural span and load, the column bases of flexible photovoltaic support structures can be rigidly connected or hinged to the foundation. Overall, in completed and ongoing flexible support projects, the column bases mostly employ hinged connections to achieve a reasonable distribution of internal forces within the structure.

[0003] In the finite element model of flexible supports, hinged column bases can be achieved by setting node constraints. The actual node connection form must match the calculation assumptions, i.e., releasing the column base bending moment and only bearing vertical and horizontal forces. Existing engineering projects generally achieve hinged constraints in the following two ways:

[0004] (1) Connect the steel column base plate with two pre-embedded bolts; (2) Connect the column base plate and the base with a pin. The first method cannot completely release the bending moment at the column base. The overall internal force and deformation of the flexible support, such as a large-span lightweight structure, cannot be ignored. The calculation assumptions cannot be fully realized, and it does not have the ability to adjust the individual support foundation after settlement during the later operation. Although the second method can release some bending moment, it brings great inconvenience to the on-site construction and installation. Temporary supports need to be added when the column is installed, which affects the on-site construction speed and increases the corresponding construction measures cost. It also does not have the ability to adjust the individual support foundation after settlement during the later operation.

[0005] Therefore, how to provide a component for connecting flexible photovoltaic brackets is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a component for connecting flexible photovoltaic brackets, which ensures the release of the bending moment at the bottom of the column to achieve a complete hinged connection, while also ensuring the self-stability of the steel column during installation. No additional temporary support measures are required, which helps to speed up construction, save construction costs, and also allows for the adjustment of bracket height to address individual bracket foundation settlement during later operation.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a component for connecting flexible photovoltaic brackets, comprising:

[0008] For connecting the steel column under the flexible photovoltaic support, the bottom of the steel column is fixedly connected to the column foot connecting plate corresponding to the axial direction of the steel column, and the column foot connecting plate has two shaft holes, which are arranged vertically and horizontally.

[0009] The base is fixedly connected to the foundation. The base is provided with two spaced ear plates. The column foot connecting plate is inserted between the two ear plates. The two ear plates are coaxially provided with a pair of support holes and a pair of adjustment waist holes. The adjustment waist holes are located above the support holes.

[0010] Pin A, which passes through the support hole and the shaft hole on the lower side of the column base connecting plate, is used to bear the load of the column base connecting plate and the steel column.

[0011] Pin B is detachably connected to the shaft hole on the upper side of the adjusting waist hole and the column base connecting plate. Pin B, together with pin A, realizes the self-stability of the steel column.

[0012] The beneficial effects of this utility model are as follows: A pair of support holes and a pair of adjustment holes are provided on the two ear plates of the base, which are used in conjunction with pin A and pin B. Pin A is the main load-bearing component, which is used to support the vertical and horizontal loads of the steel column and the column base connecting plate. Due to the presence of pin A, the bending moment between the column base connecting plate and the base can be released. The purpose of setting pin B is to cooperate with pin A to achieve the self-stability of the steel column, without the need to add external temporary support measures, which is conducive to the construction progress and saves construction costs. After the connection of the steel column is completed, pin B can be removed for subsequent reuse, saving resources and facilitating installation and disassembly.

[0013] Preferably, there is an assembly gap between the column base connecting plate and the ear plate, and there is an assembly gap between the outer wall of the pin A and the inner wall of the bottom shaft hole of the column base connecting plate.

[0014] The resulting technical effect is that the column base connecting plate and the ear plate are not fixed. It can be understood that the two ear plates have a certain clamping effect on the column base connecting plate. The pin A is fitted with the shaft hole on the column base connecting plate with clearance, thereby ensuring the release of bending moment between the column base connecting plate and the base.

[0015] Preferably, a plurality of ribs are provided between the ear plate and the base, and the ribs are located on the outer side of the two ear plates.

[0016] The resulting technical effect is that the ribs can enhance the connection reliability between the base and the ear plate, improve the load-bearing capacity of the base and the ear plate, and the ribs will not interfere with the column base connection plate.

[0017] Preferably, the ribs are arranged in pairs on the outside of the ear plate, and the ribs are triangular plates.

[0018] The resulting technical effect is that the addition of triangular ribs improves the overall structural integrity of the base.

[0019] Preferably, the opening direction of the adjusting waist hole is parallel to the axial direction of the steel column, and the center of the adjusting waist hole and the center of the support hole are located on the central axis of the ear plate.

[0020] The resulting technical effect is that the adjusting waist hole is located above the support hole, and its opening direction corresponds to the axis of the steel column, which can realize the adjustment of the pin position during the later foundation settlement.

[0021] Preferably, a plurality of pre-embedded bolts are provided between the base and the foundation, and the base is fixedly connected to the foundation by the plurality of pre-embedded bolts.

[0022] The resulting technical effect is that the pre-embedded bolts are embedded in the fixed foundation, and the base is stably connected to the foundation through the pre-embedded bolts. The stability of the base directly affects the installation effect of the flexible photovoltaic bracket.

[0023] Preferably, the center distance between the two shaft holes on the column base connecting plate is the same as the center distance between the support hole and the adjustment waist hole on the same ear plate.

[0024] The resulting technical effect is that the center distance between the two shaft holes is the same as the center distance between the support hole and the adjusting waist hole, which facilitates the installation and removal of pin A or pin B later.

[0025] Preferably, the diameter of the shaft hole and the support hole are the same, and the minor diameter of the adjusting waist hole is the same as the diameter of the support hole.

[0026] The resulting technical effect is that the standardized shaft holes and support holes facilitate product processing.

[0027] Preferably, both the column base connecting plate and the base are steel structural components.

[0028] The resulting technical effect is that steel structural components can ensure the structural strength of column base connecting plates and bases, as well as the connection stability and service life of connecting components.

[0029] Preferably, the distance between the support hole and the top of the base is greater than the distance between the lower side shaft hole of the column base connecting plate and the bottom of the column base connecting plate.

[0030] The resulting technical effect is that this distance restriction ensures the necessary assembly of the column base connecting plate and the base, and ensures the smooth installation of pin A. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See appendix to this utility model Figures 1 to 4 According to an embodiment of the present invention, a component for connecting flexible photovoltaic brackets includes:

[0038] The steel column 1 is used to connect to the bottom of the flexible photovoltaic support. The bottom of the steel column 1 is fixedly connected to the column foot connecting plate 11 corresponding to the axial direction of the steel column. The column foot connecting plate 11 has two shaft holes, which are arranged at intervals.

[0039] The base 2 is fixedly connected to the foundation. The base 2 is provided with two ear plates 21 spaced apart. The column foot connecting plate 11 is inserted between the two ear plates 21. The two ear plates 21 are coaxially provided with a pair of support holes 23 and a pair of adjustment waist holes 22. The adjustment waist holes 22 are located above the support holes 23.

[0040] The center distance between the two shaft holes is actually equal to the center distance between the support hole and the adjusting waist hole, but the inner diameter of the shaft hole is smaller than the long diameter of the adjusting waist hole.

[0041] Pin A3 passes through the support hole 23 and the shaft hole on the bottom side of the column base connecting plate 11. Pin A3 is used to bear the load of the column base connecting plate 11 and the steel column 1. Pin A is the main load-bearing component.

[0042] Pin B4 is detached and connected to the adjusting waist hole 22 and the shaft hole on the top side of the column base connecting plate 11. Pin B4 works with pin A3 to achieve the self-stability of the steel column 1. Pin B is used during the installation of the steel column and can be disassembled and reused later.

[0043] In other embodiments, there is an assembly gap between the column base connecting plate 11 and the ear plate 21, and an assembly gap between the outer wall of the pin A3 and the inner wall of the bottom shaft hole of the column base connecting plate 11, so as to realize the release of bending moment between the column base connecting plate and the base.

[0044] In other embodiments, four ribs 24 are provided between the ear plate 21 and the base 2. The ribs 24 are located on the outside of the two ear plates 21. It can be understood that the ribs are triangular plates, and two ribs 24 are provided on the outside of one ear plate to improve the overall structural level of the base.

[0045] In other specific embodiments, the opening direction of the waist hole 22 is adjusted to be parallel to the axis of the steel column 1, and the center of the waist hole 22 and the center of the support hole 23 are located on the central axis of the ear plate 21, which facilitates the adjustment of the connection position between the column foot connecting plate and the base ear plate in the later stage.

[0046] In some other embodiments, a plurality of pre-embedded bolts 6 are provided between the base 2 and the foundation 5, and the base 2 is fixedly connected to the foundation 5 by the plurality of pre-embedded bolts 6. The base is located under the path of the flexible support installation.

[0047] Specifically, the center distance between the two shaft holes on the column base connecting plate 11 is the same as the center distance between the support hole 23 and the adjusting waist hole 22 on the same ear plate 21.

[0048] The shaft hole and the support hole 23 have the same diameter. The minor diameter of the adjusting waist hole 22 is the same as the diameter of the support hole 23, so that the foundation settles later and the pin B has an adjustment range when it is reinstalled.

[0049] In practice, both the column base connecting plate 11 and the base 2 are steel structural components, which ensures the connection strength of the components and also guarantees their service life.

[0050] In some other embodiments, the distance between the support hole 23 and the top of the base 2 is greater than the distance between the lower shaft hole of the column base connecting plate and the bottom of the column base connecting plate 11, thereby satisfying the assembly conditions of the column base connecting plate 11 and the base 2 and ensuring the smooth assembly of the pin A.

[0051] This utility model also discloses a method for hinged connection of column bases of flexible photovoltaic support, which uses the above-mentioned components and includes the following steps:

[0052] Step 1: Under the corresponding installation path of the flexible photovoltaic bracket, fix the base to the pre-embedded bolts on the foundation;

[0053] Step 2: Insert the column base connecting plate between the two ear plates on the base, and align the pair of support holes with the shaft hole on the bottom side of the column base connecting plate. At the same time, pass pin A through the pair of support holes and the shaft hole on the bottom side of the column base connecting plate, and pass pin B through the pair of adjustment waist holes and the shaft hole on the top side of the column base connecting plate. At this time, pin A and pin B work together to achieve the stability of the steel column itself.

[0054] Step 3: After completing the prestressing of the flexible photovoltaic support and ensuring the verticality of all steel columns, remove pin B for subsequent reuse.

[0055] If subsequent adjustments to the steel columns are required, proceed to step four: During later operation, foundation settlement may occur due to geological defects or stress issues, causing some bases under the flexible photovoltaic support installation path to sink. In this case, the pin B removed in step three will be re-inserted into a pair of adjustment waist holes and the shaft hole on the top side of the column base connecting plate. At the same time, pin A will be removed. Pin B will change position within the adjustment waist hole. After pin B is adjusted to the correct position, stop plates will be welded to the ear plate corresponding to the upper and lower positions of pin B to complete the height positioning of pin B. The removed pin A can be reused later.

[0056] Compared with the existing column base hinge method in engineering, this utility model ensures the release of column base bending moment. While achieving complete hinge, the steel column achieves self-stability during installation through the combined action of pin A and pin B, as well as the clamping effect of the ear plate. No additional temporary support measures are required, which helps to speed up construction, save construction costs, and pin B can be reused, saving resources. By adjusting the position of pin B in the adjustment hole and cooperating with the stop plate, the height of the support can be adjusted due to the settlement of individual support foundations during later operation, making it highly applicable.
