Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic support structure for parking lots, and specifically relates to a combination structure of a single-row column truss and truss arch. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in car ownership, the parking problem has become increasingly prominent, driving the sustained growth of market demand in the parking industry. Open-air parking lots, as one of the main parking facilities, face even more urgent parking needs in key areas such as city centers, residential communities, hospitals, schools, and transportation hubs. To meet the ever-increasing parking demand, various regions have intensified their planning and construction efforts for open-air parking lots. At the same time, the increasing public awareness of environmental protection and renewable energy has also promoted market demand for the integration of the photovoltaic industry with parking facilities.

[0003] As the scale of photovoltaic carport construction, which boasts significant economic and social benefits, continues to expand, the structural defects of the original single-row column carport structure are becoming increasingly prominent. Traditional single-row column carport structures mainly consist of columns, crossbeams, longitudinal beams, and purlins, reinforced with a certain number of shear beams; the structural components are primarily made of I-beams or steel pipes. After installing photovoltaic panels on top of the carport, the stress system of the carport support changes, leading to insufficient load-bearing capacity of the crossbeams and deformation. This restricts the width and height of the carport, making it unsuitable for larger vehicles. Increasing the width and height requires adding more reinforcement components and using a larger structure, significantly increasing the construction cost of photovoltaic carports. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of traditional single-row column carport structures by providing a combined structure of single-row column truss and truss arch for photovoltaic supports in parking lots.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A single-row column truss and truss arch combination structure for photovoltaic brackets in parking lots includes a roof support structure and a single-row column support structure; there are two or more single-row column support structures arranged below the roof support structure; each single-row column support structure includes columns, truss arches and crossbeams; the middle part of the crossbeam is installed on the column; there are two truss arches, symmetrically arranged on both sides of the column, and the top of the truss arch is connected to the crossbeam.

[0007] In this invention, the traditional diagonal bracing in a single-row column support structure is preferentially replaced by a truss arch. The truss arch combines a truss structure and an arch structure (curved arch legs), resulting in superior load-bearing performance. The truss arch not only increases the span of the carport structure but also gives the building a more unique shape and visual impact. When bearing vertical loads, the curved arch legs, in addition to transmitting axial force components similar to ordinary inclined legs, fully activate the mechanical properties of the arch. The horizontal thrust generated by the arch interacts with the vertical force system of the truss, forming a self-balancing mechanism that effectively alleviates the concentration of vertical reaction forces at the supports, making the overall structural force distribution more uniform and reasonable. Compared to straight-leg double-sided cantilever trusses, it can accommodate larger load scales. Due to the curved shape of the arch, the internal bending moment distribution changes under load. Based on the mechanical principles of arches, the area from the arch foot to the arch crown converts part of the bending moment into axial force, which works in conjunction with the truss members to bear the load, reducing the peak bending moment in key areas, lowering the bending stress of the members, increasing the structural load-bearing redundancy, and enhancing the ability to resist extreme load conditions.

[0008] As a further explanation of this utility model, the lower chord of the truss arch is a semi-arched member, with one end fixedly connected to the column and the other end fixedly connected to the crossbeam.

[0009] As a further explanation of this utility model, the crossbeam is a truss. Both the crossbeam and the diagonal bracing (truss arch) adopt a truss structure, which greatly improves the stress situation of the single-row column-supported structure, making it easier for the crossbeam to be designed to expand outwards and increase the width of the photovoltaic carport. Due to the curved shape of the arch, the distribution of bending moments inside the structure changes under load. According to the mechanical principles of arches, the area from the arch foot to the arch top converts part of the bending moment into axial force, which works together with the truss members to bear the load, reducing the peak bending moment in key parts, reducing the bending stress of the members, improving the structural load-bearing redundancy, and enhancing the ability to resist extreme load conditions. Under the action of dynamic loads such as wind loads and earthquakes, the flexible deformation characteristics of the arch combined with the rigid system of the truss gives the structure good dynamic adaptability. The arch can buffer the instantaneous impact energy with its own elastic deformation, while the truss ensures that the overall structure does not become unstable. The two work together to effectively suppress structural vibration acceleration, reduce the possibility of resonance, and provide reliable safety for the building in complex dynamic environments.

[0010] As a further explanation of this utility model, the upper chord of the truss arch and the lower chord of the crossbeam are the same rod.

[0011] As a further explanation of this utility model, the column is a steel-concrete composite column. Using a steel-concrete composite column greatly improves the column's strength, allowing for greater height construction with the same diameter. Of course, when the need for increased height is not significant, traditional I-beam components can also be used. A steel-concrete composite column is a composite structure formed by pouring concrete into a steel tube. Under stress, the steel tube constrains the core concrete, placing it in a triaxial compression state. This constraint significantly improves the compressive strength of the concrete, delays the development of longitudinal micro-cracks, and allows the concrete to withstand greater axial pressure. Simultaneously, the concrete, in turn, supports the steel tube wall, preventing premature local buckling of the steel tube and allowing it to fully utilize its strength characteristics. The two work together to bear external forces. Compared to a simple reinforced concrete column, due to the constraint effect of the steel tube, its ultimate bearing capacity is significantly improved, effectively reducing the column cross-sectional size, offering clear advantages in high-rise buildings and other structures with high space utilization requirements. Furthermore, during the stress process, its load-displacement curve often exhibits a relatively stable upward trend before reaching the ultimate load, demonstrating good ductility and showing obvious deformation precursors before failure, which is beneficial to the structural safety. When subjected to bending moments, the stress distribution in the cross-section of a steel-concrete composite column is relatively complex, with both the steel tube and concrete contributing their stiffness to resist the tensile and compressive stresses generated by the bending moment. Due to the high tensile and compressive strength of the steel tube, it can share the bending moment with the core concrete, enhancing the overall bending resistance. Regarding shear resistance, the steel tube itself can effectively resist a portion of the shear force, and through bonding and interaction with the concrete, it can also improve the structure's shear bearing capacity, showing a significant improvement in shear resistance compared to ordinary concrete columns. Simultaneously, steel-concrete composite columns offer better impact resistance. When applied to parking lot canopy supports, they can effectively prevent deformation of the canopy supports due to vehicle collisions, thereby preventing the stress on the entire canopy structure.

[0012] As a further explanation of this utility model, the ceiling support structure includes boundary longitudinal beams, intermediate longitudinal beams, and longitudinal purlins; both the boundary longitudinal beams and the intermediate longitudinal beams are trusses; and a plurality of longitudinal purlins are provided and arranged between the boundary longitudinal beams and the intermediate longitudinal beams.

[0013] As a further explanation of this utility model, at least one reinforcing longitudinal beam is arranged between the boundary longitudinal beam and the intermediate longitudinal beam; the reinforcing longitudinal beam is a truss.

[0014] In this invention, the boundary longitudinal beams, intermediate longitudinal beams, and reinforcing longitudinal beams of the ceiling support structure all utilize truss structural members. These are combined with the crossbeams of the single-row column support structure (which also utilize truss structural members) to form a grid-like arrangement of truss structural members. The longitudinal trusses (i.e., reinforcing longitudinal beams) cooperate with other structural components (such as columns and crossbeams) to form a spatial force-bearing system. The longitudinal trusses participate in force-bearing both in-plane and out-of-plane. In the plane, they work with the crossbeams and columns to resist the internal forces generated by horizontal and vertical loads, constraining structural deformation. Out-of-plane, they enhance the lateral stability and torsional resistance of the entire structure, preventing lateral instability and thus strengthening the entire structural system's ability to resist horizontal forces such as wind loads and seismic forces. This reduces the risk of structural failure due to instability and provides strong protection for the safety of the structure during long-term use.

[0015] As a further explanation of this utility model, the ceiling support structure also includes transverse purlins; several transverse purlins are provided and arranged between two single-row column support structures. Adding transverse purlins can reduce the calculated span of the longitudinal purlins and improve the bending resistance and stability of the longitudinal purlins.

[0016] As a further explanation of this utility model, a reinforcing crossbeam is provided between the two single-row column support structures, and the reinforcing crossbeam is connected to the longitudinal purlins. The reinforcing crossbeam is preferably a truss, but a general I-beam can also be used depending on the actual construction requirements (such as when the transverse span requirement of the carport is not high). Setting several reinforcing crossbeams on the longitudinal purlins can effectively reduce the calculated span of the longitudinal purlins and greatly improve the bending resistance and stability of the longitudinal purlins.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Material saving: Through reasonable structural design and material selection, the combined structure of this utility model can save material costs to the maximum extent while ensuring structural performance.

[0019] 2. Construction efficiency: Due to the relatively simple structure of this utility model, prefabrication and on-site assembly can be used during construction, which greatly improves construction efficiency.

[0020] 3. Space utilization: The structural features of this utility model enable more efficient use of the interior space of the building, providing more possibilities for architectural design. Attached Figure Description
