Description
Technical Field
[0001] The utility model relates to a steel column concrete - wrapped anti - collision structure, belonging to the field of building technology. Background Art
[0002] In industrial factories and logistics warehouses, for the convenience of loading and unloading 22 - meter - long container trucks in rainy days, the loading and unloading steel - structure awning of the falling column usually has a net depth of more than 22 meters and needs to set steel columns as supports. During operation, large trucks often inevitably collide with the weak steel columns. Traditional anti - collision bars cannot withstand the strong impact of large trucks and cannot provide reliable anti - collision protection for steel columns. Therefore, it is required to provide a new type of steel column concrete - wrapped anti - collision method that can meet the strong impact of large trucks under the loading and unloading awning, make up for the limitations of conventional methods, and at the same time can meet the actual functional requirements such as firmness and impact resistance to ensure that the steel columns are not impacted.

[0007] Preferably, the steel column is an I - shaped steel or a square steel column.
[0008] Preferably, the steel column is connected to the extruded polystyrene board through an adhesive. The extruded polystyrene board is a buffer structure between the concrete anti - collision coating and the steel column, effectively avoiding the problem that gaps are easily generated when the concrete anti - collision coating is in direct contact with the steel column. The extruded polystyrene board is a finished component with low cost and convenient procurement, meeting the requirements of different enterprises.
[0009] Preferably, the thickness of the extruded polystyrene board is 10 mm.
[0010] Preferably, the concrete anti - collision coating structure is a cylinder. The concrete anti - collision coating structure has a low construction cost and convenient construction, and is more conducive to implementation and promotion.
[0011] More preferably, the minimum distance between the outer edge of the concrete anti - collision coating structure and the steel column is 100 mm; the top surface of the concrete anti - collision coating structure is an arc surface with a height of 100 mm to avoid the concrete from hitting and chipping.
[0012] Preferably, the height of the concrete anti-collision coating structure is 1000 - 1300 mm.
[0013] Preferably, steel bars are evenly distributed on the inner side of the outer edge of the concrete anti-collision coating structure.
[0014] More preferably, the diameter of the steel bars is 14 mm, and the spacing between adjacent steel bars is 150 - 200 mm.
[0015] The concrete anti-collision coating structure is painted with yellow and black warning paint, which can play a certain visual reminder role, especially during night operations.
[0016] Through the reasonable setting of the nodes, the utility model forms an effective structure with reasonable structure, simplicity and beauty, and can meet the actual use requirements such as firmness, durability and collision resistance.
[0017] Adopting the technical solution provided by the utility model, the cylindrical concrete anti-collision tightly wraps the steel column, and the internal circumferential reinforcement is arranged to form a firm and reliable anti-collision concrete column. The top arc surface is treated smoothly, which is not easy to collide, accumulate dust and have corners missing, and maximally solves the adverse effects of large truck impacts on the steel column. This node is not only convenient for construction, but also has innovation, practicability and beauty, and is durable at the same time, greatly saving the construction cost.

[0025] The steel column 1 is an I-shaped steel or a square steel column, and in this embodiment, it is an I-shaped steel.
[0026] The steel column 1 is connected to the polystyrene extruded board 2 by an adhesive.
[0027] The thickness of the polystyrene extruded board 2 is 10 mm.
[0028] The concrete anti-collision covering structure 3 is a cylinder.
[0029] The minimum distance between the outer edge of the concrete anti-collision covering structure 3 and the steel column 1 is 100 mm; the top surface of the concrete anti-collision covering structure 3 is a curved surface with a height of 100 mm.
