Description

Technical Field

[0001] This utility model relates to the field of composite steel grating, specifically a composite sloping steel grating. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, various slope engineering projects are increasingly widely used in transportation, construction, water conservancy and other fields. As an important structure connecting areas of different heights, the selection of surface paving materials for slopes is crucial. They must not only meet basic load-bearing requirements, but also adapt to complex terrain changes and long-term use needs. In the transportation field, such as slope protection for highways and railways, as well as steep sections of urban roads, materials with good anti-slip properties and drainage functions are required to ensure vehicle driving safety. Steel grating, as a metal mesh structure made of load-bearing flat steel and crossbars orthogonally combined and welded or press-locked at a certain interval, has gradually become an ideal material for slope paving due to its advantages such as light weight, high strength, ventilation and light transmission, and good anti-slip properties.

[0003] Existing slope steel grating technology has significant drawbacks, failing to meet the demands for efficient construction and long-term stability in complex environments. Regarding connection methods, traditional steel gratings primarily employ bolting or welding. Bolted connections require pre-drilling holes at the grating edges, necessitating individual bolt tightening during construction. This is not only time-consuming and labor-intensive, but also prone to loosening due to long-term vibration or rain erosion in sloping environments, leading to connection failure. While welded connections offer higher strength, they require stringent construction conditions, specialized equipment, and skilled technicians. Furthermore, stress concentration at weld points can easily occur, leading to cracks under varying slope loads, compromising overall structural safety. Traditional connection methods lack a coordinated locking mechanism for both horizontal and vertical directions. Under complex slopes or dynamic loads, steel gratings are prone to misalignment or separation. In terms of support performance, existing steel gratings typically use fixed support structures, and the support direction and strength cannot be adjusted according to the slope or force direction. When laid on slopes, fixed supports cannot effectively disperse pressure, leading to local stress concentration and accelerating the deformation and damage of the steel grating. Especially when subjected to long-term vehicle traffic or natural environmental erosion, the rigid design of fixed supports lacks elastic buffering and cannot absorb impact energy, further shortening the service life of the steel grating. Utility Model Content

[0004] The purpose of this utility model is to provide a combined sloping steel grating to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite sloping steel grating, comprising:

[0007] The steel plate body has a connecting assembly on its side surface. The connecting assembly includes a horizontal component and a vertical component. The horizontal component includes a mounting protrusion. The mounting protrusion is located on one side surface of the steel plate body. The mounting protrusion has two lifting connecting strips inside. The opposite sides of the two lifting connecting strips have multiple connecting round posts. The surface of the mounting protrusion has round holes that mate with the connecting round posts.

[0008] Furthermore, the vertical component includes a connecting slot, which is disposed on one side surface of the steel plate body. The inner side surface of the connecting slot is provided with a locking groove. The side surface of the steel plate body opposite to the connecting slot is provided with a long strip top block. The upper and lower surfaces of the long strip top block are provided with small spring rods, and one end of the small spring rod is provided with a locking protrusion that cooperates with the locking groove.

[0009] Furthermore, the side surface of the lifting connecting bar is provided with two sliding side blocks, the side surface of the steel plate body is provided with a sliding groove to facilitate the sliding of the sliding side blocks, and the side surface of the two lifting connecting bars that are close to each other is provided with a connecting long groove. A connecting spring is provided inside the connecting long groove, and the two connecting long grooves are connected by the connecting spring.

[0010] Furthermore, a mounting groove plate is provided on the side of the steel plate body facing away from the mounting protrusion, an internal protrusion is provided inside the mounting groove plate, and a circular hole corresponding to the surface of the mounting protrusion is opened on the surface of the mounting groove plate.

[0011] Furthermore, a support component is provided on the side surface of the steel plate body. The support component includes two adjustment straps, which are respectively provided on the two side surfaces of the steel plate body.

[0012] Furthermore, the upper surface of the adjusting outer belt is provided with an adjusting movable strip, and the interior of the adjusting outer belt is provided with a plurality of internal support cylinders, and the interior of the internal support cylinders is provided with support springs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this solution, by setting up connecting components, the double locking structure of horizontal and vertical joints achieves a dual improvement in the speed and stability of steel grating splicing. In the horizontal connection, the lifting connecting strip inside the mounting protrusion slides automatically after being squeezed, so that the connecting round pile is accurately embedded into the mounting groove plate. With the counter-pull force of the connecting spring, the horizontal splicing is ensured to be tight and gapless. In the vertical connection, the small spring rod of the long strip top block and the automatic locking mechanism of the locking protrusion achieve tool-free and quick fixation of the vertical splicing. This significantly improves the splicing efficiency and tensile strength of steel grating in complex terrain and solves the technical problems of easy loosening and long splicing time of traditional connection methods.

[0015] 2. In this solution, by setting up supporting components and using an adjustable elastic support structure, the dynamic adaptation and long-term stability of the support strength of the sloping steel grating are achieved. The combination of the internal support cylinder and support spring inside the outer layer allows workers to adjust the movable strip laterally to adjust the support spring to a vertical state, forming an elastic support system. When the main body of the steel plate is under pressure, the support spring disperses the pressure through elastic deformation. At the same time, the rotation mechanism of the internal support cylinder ensures the accuracy of the support direction, improves the load-bearing capacity of the steel grating in the sloping environment, and reduces material fatigue and extends service life through elastic buffering.

[0021] 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.

[0022] Example 1: Please refer to Figures 1 to 4 A composite sloping steel grating, comprising:

[0023] The steel plate body 1 has a connecting assembly on one side surface. The connecting assembly includes a horizontal component and a vertical component. The horizontal component includes: a mounting protrusion 2, which is located on one side surface of the steel plate body 1. The mounting protrusion 2 has two lifting connecting bars 13 inside. Multiple connecting round posts 14 are provided on the opposite side surface of the two lifting connecting bars 13. The surface of the mounting protrusion 2 has round holes that mate with the connecting round posts 14. Two sliding side blocks 15 are provided on the side surface of the lifting connecting bars 13. A sliding groove is provided on the side surface of the steel plate body 1 to facilitate the sliding of the sliding side blocks 15. A connecting long groove 16 is provided on the adjacent side surface of the two lifting connecting bars 13. The part is provided with a connecting spring 17, and the two connecting long slots 16 are connected by the connecting spring 17. The side surface of the steel plate body 1 opposite to the mounting protrusion 2 is provided with a mounting slot plate 3. The inside of the mounting slot plate 3 is provided with an internal protrusion 8. The surface of the mounting slot plate 3 is provided with a round hole corresponding to the surface of the mounting protrusion 2. The vertical component includes a connecting slot 4. The connecting slot 4 is provided on one side surface of the steel plate body 1. The inner side surface of the connecting slot 4 is provided with a locking slot 5. The side surface of the steel plate body 1 opposite to the connecting slot 4 is provided with a long strip top block 6. The upper and lower sides of the long strip top block 6 are provided with small spring rods. One end of the small spring rod is provided with a locking protrusion 7 that cooperates with the locking slot 5.

[0024] During assembly, when the workers horizontally join two steel gratings together, they insert the mounting protrusion 2 of one steel plate into the mounting groove 3 of the other steel plate. The lifting connecting strip 13 inside the mounting protrusion 2 is squeezed by the internal protrusion 8 inside the mounting groove 3, and slides along the groove through the sliding side block 15, so that the connecting round pile 14 passes through the round hole on the surface of the mounting protrusion 2 and is embedded in the corresponding round hole of the mounting groove 3, ensuring a tight connection. When vertical splicing is performed, the long strip top block 6 of one steel plate is inserted into the connecting slot 4 of the other steel plate. The small spring rods on the upper and lower sides of the long strip top block 6 are compressed and contracted, which drives the locking protrusion 7 to be embedded into the locking slot 5 on the side wall of the connecting slot 4. Automatic locking is achieved through the spring force, thereby achieving the effect of connecting multiple steel plate main bodies 1.

[0025] The side surface of the steel plate body 1 is also provided with a support component, which includes: two adjusting outer belts 9, which are respectively provided on the two sides of the steel plate body 1, and an adjusting movable strip 11 is provided on the upper surface of the adjusting outer belts 9. Multiple internal support cylinders 10 are provided inside the adjusting outer belts 9, and a support spring 12 is provided inside the internal support cylinders 10.

[0026] When the steel grating is laid on a slope, the workers can move the adjusting slide 11 laterally to move the adjusting belt 9, thereby rotating the internal support cylinder 10 and adjusting the support spring 12 inside the internal support cylinder 10 to a vertical state. During use, when the steel plate body 1 is under pressure, the support strength of the steel plate body 1 can be improved through the combined action of the internal support cylinder 10 and the support spring 12.

[0027] Working principle:

[0028] During assembly, in the horizontal splicing, the mounting protrusion 2 of one steel plate body 1 is inserted into the mounting groove 3 of another steel plate body 1. The internal protrusion 8 in the mounting groove 3 presses against the two lifting connecting strips 13 in the mounting protrusion 2. The lifting connecting strips 13 slide along the sliding groove on the side surface of the steel plate body 1 with the help of the sliding side block 15 on the side surface, so that the connecting round pile 14 of the two lifting connecting strips 13 on the opposite side passes through the round hole on the surface of the mounting protrusion 2 and is embedded in the corresponding round hole of the mounting groove 3, so as to achieve a tight horizontal connection. In the vertical splicing, the long strip top block 6 of one steel plate body 1 is inserted into the connecting slot 4 of another steel plate body 1. The small spring rods on the upper and lower sides of the long strip top block 6 are compressed and contracted, which drives the locking protrusion 7 to be embedded into the locking slot 5 on the side wall of the connecting slot 4, and automatically locks by the spring force.

[0029] When the steel grating is laid on the slope, the workers move the adjusting movable strip 11 on the outer belt 9 laterally to make the inner support cylinder 10 inside the outer belt 9 rotate, and adjust the support spring 12 inside the inner support cylinder 10 to a vertical state. When the steel plate body 1 is under pressure, the support spring 12 and the inner support cylinder 10 work together to increase the support strength.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
