A steel structure for an electric bicycle charging station

Abstract

This utility model discloses a steel structure for an electric bicycle charging station, comprising a steel structure formed by connecting several columns and several vertical beams, with several horizontal beams between adjacent vertical beams. The key feature is that each horizontal beam has a clearance portion, the bottom surface of which is connected to the side of the vertical beam via fasteners, and the end face of the clearance portion forms an assembly gap with the side of the vertical beam. This utility model, through a slit clearance structure combined with a 1-10mm assembly gap, can adaptively compensate for positive and negative tolerances, avoiding installation interference or loose connections caused by dimensional errors in traditional structures. The bearing surface at the slit forms a double bearing structure with the upper end of the vertical beam, and with the reinforcement of the triangular extension end and the connecting end, it significantly improves the node bearing capacity and overall structural stability while ensuring convenient installation. This reduces the requirements for the machining accuracy of the horizontal beams and eliminates safety hazards caused by dimensional errors.

Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure for an electric bicycle charging station. Background Technology

[0002] The steel structure of the electric bicycle charging station mainly includes vertical columns in the vertical direction and horizontal beams. The beams are evenly laid on the vertical beams to form a complete support frame. During assembly, the columns and beams are usually installed first to form a frame structure. Then, according to the spatial layout, the beams are installed in the frame to form a support plane. Finally, plates are laid on the beams to form a load-bearing plane. However, once the columns and vertical beams are installed, the length of the horizontal beam is fixed. In actual installation, the horizontal beam is fixed to the side of the vertical beam through the end face. If there is a length error during processing, the horizontal beam with positive tolerance will be too long and limit the inner width dimension, while the horizontal beam with negative tolerance will be too short and bend the vertical beam, resulting in installation difficulties, deformation of the frame structure, and even safety hazards.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example Reference Figures 1 to 6 This embodiment of the present invention provides a steel structure 100 for an electric bicycle charging station, comprising a frame formed by connecting several columns 200 (Q235B galvanized square tubing) and several vertical beams 300 (Q235B galvanized C-shaped steel). Several horizontal beams 400 (Q235B irregular cold-formed steel beams) are provided between adjacent vertical beams 300. Each horizontal beam 400 has a clearance portion at its end. The bottom surface of the clearance portion is fixedly connected to the side surface of the vertical beam 300 by fasteners 500, and the end face of the clearance portion is flush with the vertical beam. The side of beam 300 forms an assembly gap of 1-10mm. The clearance portion includes a notch 401a at the end of the crossbeam 400, with the opening direction of the notch 401a facing the side of the vertical beam 300. The crossbeam 400 may have a notch 401a at either end or both ends. The bottom surface of the clearance portion is the bottom surface of the crossbeam 400. It is locked and fixed to the side of the vertical beam 300 by fasteners 500. The end face of the clearance portion is the gap between the surface of one end of the crossbeam 400 and the side of the vertical beam 300. Figure 2As shown, the side of the vertical beam 300 is composed of the outer surface of the middle end 301 of the vertical beam, the bottom surface of the upper end 302 of the vertical beam, and the top surface of the lower end 303 of the vertical beam. The side of the horizontal beam 400 is composed of the outer surface of the middle end 401 of the horizontal beam, the bottom surface of the upper end 402 of the horizontal beam, and the top surface of the lower end 403 of the horizontal beam. The slit 401a is opened on the middle end 401 of the horizontal beam to avoid the side of the vertical beam 300. After installation, a gap of 1-10mm is maintained between one end of the horizontal beam 400 and the side of the vertical beam 300. During assembly, the bearing surface 401a-1 of the slit 401a contacts the upper surface of the upper end 302 of the vertical beam and shares the load with the bottom of the lower end 403 of the horizontal beam. At the same time, the triangular extension end 405 at the slit 401a and the connection end 404 between the upper end 402 and the lower end 403 of the horizontal beam enhance the structural strength of the horizontal beam 400. The extension end 405 is also used to further avoid interference from the side of the vertical beam 300. During installation, first, vertically fix the column 200 to the foundation (or install a separate support frame for ground fixing), and initially connect it to the vertical beam 300 using L-shaped angle brackets; then, align the cutout 401a at the end of the crossbeam 400 with the C-shaped opening of the vertical beam 300 and insert it, ensuring that the bearing surface 401a-1 is in complete contact with the upper end 302 of the vertical beam, and adjust it to a gap of 1-10mm (1-10mm is the total redundancy); next, install the pad 501 with the oblong hole 501a, and tighten it with M12 screws 503 and washers 502, tightening it twice to 45N·m; finally, conduct a 300kg static load test to verify that the cutout contact surface does not separate and the deformation meets the standard, and apply an anti-corrosion layer to the joint; throughout the process, verticality, gap, and torque values ​​need to be continuously monitored, and any abnormalities are dealt with by repairing the cutout burrs or adding adjusting pieces; It is worth mentioning that the shear 401a avoidance structure, combined with a 1-10mm assembly gap, can adaptively compensate for positive and negative tolerances, avoiding installation interference or loosening of connections caused by dimensional errors in traditional structures; the bearing surface 401a-1 at the shear 401a and the upper end 302 of the vertical beam 300 form a double bearing structure, which, together with the reinforcement of the triangular extension end 405 and the connection end 404, significantly improves the node bearing capacity and overall structural stability while ensuring convenient installation. This reduces the requirements for the machining accuracy of the crossbeam 400 and eliminates safety hazards caused by dimensional errors. In another embodiment, such as Figure 1 , Figure 4As shown, the fastener 500 adopts an adjustable connection structure, specifically including a pad 501, a washer 502, and a screw 503. The pad 501 is connected to the bottom of the crossbeam 400 by welding or bolting, and its surface has a slotted hole 501a. During installation, the screw 503 passes through the washer 502 and the slotted hole 501a of the pad 501 in sequence and then connects to the threaded hole on the side of the vertical beam 300. The longitudinal adjustment allowance of the slotted hole 501a allows for a fine adjustment of the installation position of ±5mm. The washer 502 is placed between the pad 501 and the nut of the screw 503 to distribute the pressure at the connection and prevent damage to the surface of the component during tightening. This structure ensures the connection strength while further improving the assembly fault tolerance of the crossbeam 400 and the vertical beam 300. In another embodiment, such as Figure 1 , Figure 5 , Figure 6 As shown, a fireproof board 600 is installed between adjacent crossbeams 400. The fireproof board 600 (Luyang CY-MD-950" ceramic fiber fireproof board) is made of Class A fireproof material and has a thickness of 5-10mm. The fireproof board 600 is bonded and fixed to the side of the crossbeam 400 with high-temperature fireproof adhesive 600a (Dow Corning 997). The fire resistance limit of the fireproof adhesive 600a is not less than 2 hours and the working temperature range is -30℃ to 200℃. The upper and lower edges of the fireproof board 600 are flush with the upper end 402 and the lower end 403 of the crossbeam 400, respectively, forming a continuous fireproof isolation zone, which effectively prevents the spread of fire along the gaps between the crossbeams 400 and improves the fire safety performance of the overall structure.
