Technical Field
[0001] This utility model relates to the field of steel grating technology, specifically a composite steel grating. Background Technology
[0002] Steel grating, also known as steel grid or grating panel, is a mesh structure material made of flat steel and twisted steel welded together. Steel grating has multiple functions and uses: it can be used for load-bearing and support, capable of withstanding large loads, and is often used as the floor or floor load-bearing structure in industrial plants, warehouses, parking lots, and other places; it can be used for anti-slip and safety design, as steel grating has excellent anti-slip properties, ensuring the safety of personnel walking and equipment operation; it can also be used for ventilation and lighting, as the open mesh structure of steel grating allows air and light to pass freely.
[0003] Existing steel gratings are typically produced by welding several neatly arranged flat steel bars together to form a whole, which has high structural strength. However, this connection method usually results in steel gratings with large structural dimensions and weight, which usually takes up a lot of space during transportation, leading to high transportation costs. At the same time, the large weight also brings many inconveniences during transshipment, increasing the burden of transportation. Therefore, in order to address the above problems, a composite steel grating is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a modular steel grating, which is mainly composed of four parts: longitudinal frame plates, transverse frame plates, transverse plate frames, and longitudinal plate frames. The above components are interlocked with each other and fixedly connected by threaded connectors. The interlocking action between the structures and the fastening action of the threaded connectors can ensure the overall load-bearing capacity after connection. Based on the above solution, it can be stored in disassembled form during transportation, which can significantly reduce the space occupied. Moreover, the size and weight of each component are small, which can facilitate transportation. When needed, the components can be interlocked with each other and fixedly connected by threaded connectors to complete the overall assembly and installation. This solves the technical problems of existing steel gratings, which are usually made of several flat steel welded into a whole, occupying a lot of space during transportation, resulting in high transportation costs, and the large weight and size also causing many inconveniences during transportation.
[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0006] A composite steel grating includes longitudinal frame plates and transverse frame plates arranged perpendicularly to each other and fixedly connected at their joints with threaded connectors. A plurality of transverse frame plates are arranged in an array between the transverse frame plates and fixedly connected to the longitudinal frame plates at their ends with threaded connectors. A plurality of longitudinal frame plates are arranged in an array between the longitudinal frame plates and fixedly connected to the transverse frame plates at their ends with threaded connectors. Each transverse frame has a first joint in its middle, and each longitudinal frame has a second joint in its middle. The joints between the transverse and longitudinal frame plates are engaged by the interlocking of the first and second joints. Based on the above scheme, the steel grating is mainly composed of four parts: longitudinal frame plates, transverse frame plates, transverse plate frames, and longitudinal plate frames. These components are interlocked and fixedly connected by threaded connectors. The interlocking action between the structures and the fastening action of the threaded connectors ensure the overall load-bearing capacity after connection. Thus, it is in a disassembled state during transportation, which can significantly reduce the space occupied. Moreover, the size and weight of each component are small, which can facilitate transportation. When needed, the components are interlocked and fixedly connected by threaded connectors to complete the overall assembly and installation.
[0007] In one possible implementation, the horizontal frame includes a second frame with splicing folding plates fixedly installed at both ends, and the vertical frame includes a first frame. The splicing folding plates and the first frame are provided with several corresponding threaded holes. The above structure can realize the splicing connection between the horizontal frame and the vertical frame, thereby forming a frame as a whole, providing the necessary structural foundation for the installation and fixing of the internal horizontal and vertical frame.
[0008] In one possible implementation, the horizontal frame includes two symmetrically arranged horizontal strips, which are connected as a whole by first end plates at both ends.

This structure can connect the two horizontal strips into a whole unit with the first end plates, avoiding the cumbersome installation work caused by too many first end plates. The first end plates also provide the necessary structural foundation for the fixed connection between the horizontal strips and the first frame plate.
[0009] In one possible implementation, the longitudinal frame includes two symmetrically arranged longitudinal strips, which are connected as one unit by second end plates at both ends. The longitudinal strips have a second splice opening facing downwards. This structure can connect the two longitudinal strips into a whole unit with the second end plates, avoiding the cumbersome installation work caused by too many second end plates. The second end plates also provide the necessary structural foundation for the fixed connection between the longitudinal strips and the second frame plate.
[0010] In one possible implementation, a second guide plate is fixedly provided on the inner wall of the second frame plate, forming a guide groove that matches the size of the longitudinal plate frame. A second abutment is fixedly provided on the upper side of both ends of the longitudinal plate. When both ends of the longitudinal plate frame are fully inserted into the guide groove, the upper surface of the second guide plate is in contact with the second abutment. In the above structure, the second guide plate plays a positioning and guiding role, which can guide the end of the longitudinal plate frame to be placed in a designated position, so that the two can be fixedly connected by threaded connectors. Moreover, the interaction between the second guide plate and the second abutment can play a limiting role, preventing the end of the longitudinal plate frame from sliding out of the guide groove.
[0011] In one possible implementation, a first guide plate is fixedly provided on the inner wall of the first frame plate, forming a guide groove that matches the size of the horizontal plate frame. A first abutment plate is fixedly provided on the lower side of both ends of the horizontal plate. When both ends of the horizontal plate frame are fully inserted into the guide groove, the lower end face of the first guide plate is in contact with the first abutment plate. In the above structure, the first guide plate plays a positioning and guiding role, which can guide the end of the horizontal plate frame to be placed in a designated position, so that the two can be fixedly connected by threaded connectors. Moreover, the interaction between the first guide plate and the first abutment plate can play a limiting role, preventing the end of the horizontal plate frame from sliding out of the guide groove.
[0012] In one possible implementation, the first end plate and the first frame plate are provided with a plurality of corresponding threaded holes, wherein threaded connections are provided with threaded fasteners. The above-mentioned structural form provides the necessary structural basis for the fixed connection between the first end plate and the first frame plate.
[0013] In one possible implementation, the second end plate and the second frame plate are provided with several corresponding threaded holes, wherein threaded fasteners are threadedly connected.

[0023] like Figure 1 - Figure 2 As shown, this embodiment provides a combined steel grating, including longitudinal frame plates 1 and transverse frame plates 2, which are arranged perpendicularly to each other and fixedly connected at the splice with threaded connectors 3. A plurality of transverse frame frames 4 are arranged in an array between the transverse frame plates 2 and fixedly connected to the longitudinal frame plates 1 at their ends with threaded connectors 3. A plurality of longitudinal frame frames 5 are arranged in an array between the longitudinal frame plates 1 and fixedly connected to the transverse frame plates 2 at their ends with threaded connectors 3. A first splice 43 is provided in the middle of the transverse frame frame 4, and a second splice 53 is provided in the middle of the longitudinal frame frame 5. The junction of the transverse frame frame 4 and the longitudinal frame frame 5 is connected to the first splice 43 and the second splice 53. The interlocking connection of the two-part joint 53 is based on the above scheme. The steel grating is mainly composed of four parts: longitudinal frame plate 1, transverse frame plate 2, transverse plate frame 4 and longitudinal plate frame 5. The above components are interlocked with each other and fixedly connected by threaded connectors 3. The interlocking action between the structures and the fastening action of the threaded connectors 3 can ensure the overall load-bearing capacity after connection. Thus, it is in a disassembled state during transportation, which can significantly reduce the space occupied. Moreover, the size and weight of each component are small, which can facilitate transportation. When it is needed, the components are interlocked with each other and fixedly connected by threaded connectors 3 to complete the overall assembly and installation.
[0024] like Figure 2As shown, the horizontal frame plate 2 includes a second frame plate 21, with splicing folding plates 22 fixedly installed at both ends.

[0025] like Figure 2 , Figure 4 As shown, the horizontal frame 4 includes two symmetrically arranged horizontal strips 42. The two horizontal strips 42 are connected as one unit by first end plates 41 at both ends. The horizontal strips 42 have an upward-facing first splice 43. This structure allows the two horizontal strips 42 to be connected as a whole unit by the first end plates 41, avoiding the cumbersome installation work caused by an excessive number of first end plates 41. The first end plates 41 also provide the necessary structural foundation for the fixed connection between the horizontal strips 42 and the first frame plate 11. The vertical frame 5 includes two symmetrically arranged vertical strips 52. The two vertical strips 52 are connected as one unit by second end plates 51 at both ends. The vertical strips 52 have a downward-facing second splice 53. This structure allows the two vertical strips 52 to be connected as a whole unit by the second end plates 51, avoiding the cumbersome installation work caused by an excessive number of second end plates 51. The second end plates 51 also provide the necessary structural foundation for the fixed connection between the vertical strips 52 and the second frame plate 21.
[0026] like Figure 3 As shown, a second guide plate 23 is fixedly installed on the inner wall of the second frame plate 21, forming a guide groove that matches the size of the longitudinal plate frame 5. Second abutment plates 54 are fixedly installed on the upper sides of both ends of the longitudinal plate 52. When both ends of the longitudinal plate frame 5 are fully inserted into the guide groove, the upper surface of the second guide plate 23 is in contact with the second abutment plate 54. In this structure, the second guide plate 23 serves as a positioning guide, guiding the ends of the longitudinal plate frame 5 to a designated position, facilitating the connection of the threaded connector 3. Furthermore, the interaction between the second guide plate 23 and the second abutment plate 54 provides a limiting function, preventing the ends of the longitudinal plate frame 5 from slipping out of the guide.

In the above structure, the first guide plate 12 plays a positioning and guiding role, which can guide the end of the horizontal plate frame 4 to be placed in the designated position, so that the threaded connector 3 can fix the two together. The interaction between the first guide plate 12 and the first abutment plate 44 can play a limiting role, preventing the end of the horizontal plate frame 4 from sliding out of the guide groove.
