Description

Technical Field

[0001] This utility model belongs to the field of steel grating splicing technology, and specifically relates to quick-assembly connectors for steel grating reinforced by quick-assembly connectors. Background Technology

[0002] Steel grating, a common building and industrial material, is made of load-bearing flat steel bars and crossbars arranged at certain intervals and fixed by welding or press-locking. Due to its many advantages, such as high strength, light weight, ventilation and light transmission, slip resistance, aesthetics, and durability, it is widely used in many fields, including industrial plants, municipal engineering, ports and docks, sewage treatment plants, chemical enterprises, and construction projects. For example, in industrial plants, steel grating is often used as platforms, walkways, and stair treads; in municipal engineering, it can be used as trench covers, fences, and other facilities.

[0003] To increase the connection between two adjacent steel gratings, bolts are usually used to reinforce the connection between them. However, this method of reinforcement is inefficient and takes a long time to tighten or loosen a large number of bolts in a narrow space. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing quick-assembly connectors and steel gratings. The specific technical solution is as follows:

[0005] On the one hand, this application provides a quick-assembly connector for reinforcing two adjacent steel gratings, including a middle plate and two side plates vertically and parallelly connected to both sides of the middle plate. The side plates gradually tilt inward along the extension path towards the free end. In the splicing state, the side plates are squeezed outward and clamp the two sets of steel gratings.

[0006] As a further technical solution of this utility model, a reserved groove is provided on the inner side of the side plate, and an elastic sheet is connected to the reserved groove. The free end of the elastic sheet extends obliquely towards the middle plate. In the splicing state, the elastic sheet is pressed into the reserved groove and clamps the two sets of steel gratings.

[0007] As a further technical solution of this utility model, the pressing surface of the elastic sheet is designed to be rough.

[0008] As a further technical solution of this utility model, the quick assembly connector is an integrally formed U-shaped structure with an opening opposite to the middle plate.

[0009] As a further technical solution of this utility model, the elastic sheet is made of plastic.

[0010] As a further technical solution of this utility model, the elastic sheet is made of metal.

[0011] On the other hand, this application also provides a steel grating reinforced by the above-mentioned quick-assembly connectors, with the quick-assembly connectors reinforcing two adjacent steel gratings; the inner side of the outer frame is provided with a groove, and in the splicing state, the elastic sheet is inserted into the groove and forms anti-loosening barbs.

[0012] As a further technical solution of this utility model, the top of the outer frame has a recessed notch, and in the spliced ​​state, the middle plate is inserted into the notch and forms a plane.

[0013] The beneficial effects of this utility model are as follows:

[0014] This application eliminates the cumbersome process of traditional welding and bolting connections. It does not require professional welding equipment or complicated bolt tightening operations. Workers only need simple training to get started. It can complete the connection between steel gratings in a short time, greatly shortening the construction cycle, improving construction efficiency, and reducing labor costs. In large-scale construction projects, it can significantly accelerate the project progress and complete the project and put it into use ahead of schedule. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Figure 1 A schematic diagram of the structure after the quick-assembly connectors and steel gratings are assembled is shown; Figure 2 This diagram shows a structural schematic of the cross-section of the quick-assembly connectors and the steel grating after assembly. Figure 1 and Figure 2In this steel grating 200, there is an outer frame 210 and horizontal and vertical reinforcing bars 220 and 230 arranged intersectingly within the outer frame 210. Multiple sets of horizontal and vertical reinforcing bars 220 and 230 are provided, equidistantly arranged along the trajectory of the outer frame 210, while the horizontal and vertical reinforcing bars 220 and 230 are arranged intersectingly with each other. Figure 1 The diagram shows a vertical cross structure, but in some other embodiments, the included angle between the horizontal stiffeners 220 and the vertical stiffeners 230 is not limited; two adjacent steel gratings 200 are connected by quick-assembly connectors 100; the two steel gratings 200 are arranged neatly, that is, the outer frames 210 of the two steel gratings 200 are fitted together, and the quick-assembly connectors 100 are used to simultaneously tighten the outer frames 210 of the two steel gratings 200, thereby reinforcing the two adjacent steel gratings 200.

[0023] Figure 3 A cross-sectional structural diagram of the quick-assembly connector 100 is shown; Figure 3 In this assembly, the quick-assembly connector 100 has a U-shaped structure with an opening. The quick-assembly connector 100 includes a middle plate 110 and two side plates 120 perpendicularly connected to both sides of the middle plate 110. During operation, simply align the opening of the quick-assembly connector 100 with the outer frames 210 of the two mating steel gratings 200, and press the quick-assembly connector 100 so that the two outer frames 210 are confined within the U-shaped space of the quick-assembly connector 100. The side plates 120 gradually tilt inwards along their extension path towards the free end. In the assembled state, the side plates 120 are compressed and open outwards, clamping the two sets of steel gratings 200. Here, "inwards" refers to the side facing the U-shaped space; that is, the distance between the two side plates 120 gradually shortens. Thus, after the quick-assembly connector 100 and the steel gratings 200 are assembled, the side plates 120 deform and are stretched outwards, utilizing the two side plates 120... The inward rebound force clamps the two steel gratings 200 together, thus reinforcing them. A pre-drilled groove 121 is provided on the inner side of the side plate 120, connected to an elastic piece 122. The free end of the elastic piece 122 extends obliquely towards the middle plate 110. In the spliced ​​state, the elastic piece 122 is pressed into the pre-drilled groove 121 and clamps the two sets of steel gratings 200. The elastic piece 122 deforms as it mates with the quick-assembly connector 100, and the rebound force of the elastic piece 122 compresses the two spliced ​​steel gratings 200. Since the free end of the elastic piece 122 extends in the opposite direction of the opening, it facilitates the quick-assembly connector 100 wrapping around the outer frame 210 of the steel gratings 200. The pressing surface of the elastic piece 122 is roughened. The pressing surface of the elastic piece 122 facing the outer frame 210 can be textured to increase friction and strengthen the connection between the two.

[0024] In one embodiment, the elastic sheet 122 is made of metal, such as copper with good elasticity; the quick-assembly connector 100 is integrally molded by casting.

[0025] In another embodiment, the elastic sheet 122 is made of plastic, such as polyamide or polycarbonate, and the quick-assembly connector 100 is integrally molded by injection molding.

[0026] Figure 4 A schematic diagram of the cross-sectional structure of the outer frame 210 is shown; Figure 4 In the middle, the inner side of the steel grating 200 is provided with a groove 211. In the splicing state, the elastic piece 122 is inserted into the groove 211. When the quick-assembly connector 100 moves to the designated position, the position of the elastic piece 122 and the groove 211 correspond. The elastic piece 122 can rebound and be inserted into the groove 211 through its own elasticity, forming a barb to prevent detachment. The top of the outer frame 210 has a recessed notch 212. In the splicing state, the middle plate 110 is inserted into the notch 212 and forms a flat horizontal surface. That is to say, the depth of the notch 212 is the same as the thickness of the middle plate 110. The notch 212 can both position the middle plate 110 and hide the middle plate 110 to prevent it from bulging outward.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
