Description

Technical Field

[0001] This utility model belongs to the field of carport technology, specifically relating to a prefabricated carport. Background Technology

[0002] To promote the photovoltaic industry, it is necessary to invest in the research and development and upgrading of photovoltaic power generation equipment itself, and also to expand the application scenarios or sites that can support photovoltaic equipment. Currently, in urban areas, the primary choice is to install photovoltaic panels on building rooftops; in addition, open-air carports are also a practical and feasible area for expansion.

[0003] The current mainstream carport design uses a steel frame prefabricated structure, with the roof typically covered by a tarpaulin, resulting in a relatively lightweight structure. However, when using photovoltaic panels to cover the roof, the steel frame needs to be reinforced to support the weight of the panels. This excessive weight, however, diminishes the advantages of the lightweight, easy-to-transport, and easy-to-assemble structure. Furthermore, a pure steel frame poses a risk of electrical leakage, affecting safety. Concrete carports built using traditional on-site casting methods suffer from long construction periods, susceptibility to weather conditions, and a large amount of on-site work, making them unsuitable for rapid layout and flexible adjustments. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a prefabricated carport to solve the problem of construction efficiency of concrete structure carports.

[0005] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0006] A prefabricated carport, comprising:

[0007] The column is a precast concrete component, including a main trunk. The lower end of the main trunk is equipped with a plug-in part for connecting to the column foundation. The upper end of the main trunk branches into a first branch and a second branch, with the first branch being relatively forward. The tops of the two branches are equipped with connectors for connecting and fixing the ceiling.

[0013] Furthermore, a wire groove is provided on the rear side of the column, the wire groove extending from the top of the second branch to the upper end of the plug-in part, and the groove wall protrudes relatively from the plug-in part.

[0014] Furthermore, the column foundation includes a cup-shaped opening and a base plate. The cup-shaped opening is located on the base plate and has a square opening inside.

[0015] Furthermore, the main trunk, the first branch, and the second branch are provided with hanging points on their side walls, and the hanging points are embedded.

[0016] Furthermore, it also includes cable trenches and electrical box supports, both of which are precast concrete components.

[0017] Furthermore, the electrical box support is located above the cable trench, and the top surface has a cable passage hole connecting to the cable trench; for the part of the cable trench not covered by the electrical box support, a cover plate is provided on the top of the cable trench, and the cover plate is a precast concrete component.

[0018] Furthermore, the cable trench is composed of multiple prefabricated components spliced ​​end to end, and each prefabricated component has a sealing strip groove on its end face for placing the sealing strip; the sealing strip is a water-swellable rubber waterstop strip.

[0041] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein similar or identical reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0042] like Figure 1 The prefabricated carport shown includes columns 1, a roof 2, column foundations 3, and electrical box supports 4. Columns 1, column foundations 3, and electrical box supports 4 are all prefabricated concrete components. Column foundations 3 are buried underground to support and stabilize columns 1. Columns 1 stand upright on the ground, their lower ends fixed to column foundations 3, and their upper ends connected to the roof support bracket 21. The roof 2, covered with photovoltaic panels, is fixed to the roof support bracket 21. The electrical box supports 4 are independently located behind columns 1 (on the left side of the diagram) and are used to house electrical equipment such as electrical boxes 5 or charging piles.

[0043] like Figure 2 and Figure 3 As shown, the column 1 has a roughly Y-shaped structure, with a main trunk at the bottom. The main trunk branches upwards into two branches, one forward (first branch 11) and the other backward (second branch 12). The first branch 11 has a first connector 13 at its top, and the second branch 12 has a second connector 14 at its top. A plug-in part 16 is located at the lower end of the main trunk. A groove 15 is formed on the rear side of the column 1. Wherein:

[0044] Both the first connector 13 and the second connector 14 are steel structural components, including a top plate, a bottom plate, and a support. The bottom plate is fixedly connected to the first branch 11 or the second branch 12 via anchor bars. The support is fixed between the top plate and the bottom plate to raise the top plate for connection and fixation to the roof support 21. The top surfaces of the top plates of both the first connector 13 and the second connector 14 are on the same plane, which is inclined relative to the ground, with the first connector 13 positioned higher. The surfaces of the two top plates are each provided with several bolt holes for connecting and fixing the roof support 21.

[0045] The insertion part 16 is vertically set with a height of ≥500mm and a rough surface, and is used to insert into the ground and connect to the column foundation 3.

[0046] The wire groove 15 extends from the top of the second branch 12 to the upper end of the plug-in portion 16, and the two sides of the groove wall of the wire groove 15 protrude from the plug-in portion 16.

[0047] The main trunk, the first branch 11, and the second branch 12 are equipped with suspension points 6 on their side walls. The suspension points 6 are embedded, meaning that the suspension points are not exposed on the surface of the components.

[0048] like Figure 4 As shown, depending on the actual application or design requirements, the column 1 can also be set as an R-shaped structure, wherein the second branch 12 is set vertically along the main trunk, the first branch 11 is set obliquely upward on the front side, and the wire groove 15 is set vertically along the part from the second branch 12 to the main trunk; the top surfaces of the first connector 13 and the second connector 14 are not coplanar, and the top surface inclination angles can also be different.

[0049] like Figure 5 and Figure 6 The base 3 shown has a bottom plate 31, a cup-shaped opening above the bottom plate 31, and a square cup opening 32 inside the cup opening. Embedded suspension points 6 are provided on the bottom plate 31 located on both sides of the cup opening 32.

[0050] like Figure 7 As shown, when assembling precast components, the plug-in part 16 is inserted into the cup opening 32, and then concrete is poured between the two to make the connection between them secure.

[0051] like Figures 8-10 As shown, a cable trench 41 is located below the electrical box support 4. The cable trench 41 has a U-shaped structure and is buried underground for running cables. Four embedded suspension points 6 are evenly distributed on the top surface of the electrical box support 4, and a cable passage hole 43 connects to the cable trench 41. Outside the electrical box support 4, the top of the cable trench 41 is covered with a cover plate 42, which is flush with the ground during construction. The cable trench 41, cover plate 42, and electrical box support 4 are all precast concrete components.

[0052] like Figure 10 As shown, the cable trench 41 is composed of multiple prefabricated components spliced ​​end to end, with a sealing strip groove cut into the end face of each prefabricated component of the cable trench 41; the groove has an isosceles trapezoidal cross-section. When two adjacent prefabricated cable trench 41 components are spliced, a sealing strip 44 is installed in the sealing strip groove, and the remaining mating surfaces are filled with M15 cement mortar. The aforementioned sealing strip 44 is a water-swellable rubber waterstop strip.

[0053] In this invention, the column 1, column foundation 3, cable trench 41, and electrical box support 4 are all precast concrete components, enabling standardized factory production and ensuring consistent component quality. On the construction site, only the assembly of precast components is required, significantly shortening the construction cycle and reducing on-site labor intensity. Furthermore, these components are highly versatile, facilitating later maintenance, replacement, and expansion, effectively reducing the total life-cycle cost and adapting to the needs of large-scale, rapid construction of charging stations.
