Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, and in particular to modular composite structure steel grating. Background Technology

[0002] Steel grating is a mesh-like metal product made of flat steel bars and crossbars arranged orthogonally at a certain interval and connected by welding, riveting or press-locking processes. It has the characteristics of high strength, light weight, ventilation and light transmission, and anti-slip and wear resistance, and is used in industrial and construction fields.

[0003] A search revealed Chinese patent publication number CN220957891U, which discloses a steel grating. The steel grating includes multiple grating blades spaced apart along a first direction and connectors disposed between the multiple grating blades. The connectors connect the multiple grating blades. Grooves are provided on the upper surfaces of both the connectors and each grating blade. These grooves can receive materials and accumulate within them, creating a "material-on-material" impact mechanism. This effectively reduces the erosion of the connectors and each grating blade by subsequent incoming materials, thereby reducing the impact of continuous material impact on the anti-corrosion and wear-resistant coating on the connectors and each grating blade, ensuring the protective capability of the anti-corrosion and wear-resistant coating, and ensuring the service life of the steel grating. However, in practical use, the steel grating needs to be spliced ​​and installed to meet different usage requirements. During welding and assembly, the steel grating requires manual positioning by operators, thus reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular composite structure steel grating, which aims to improve the problem in the prior art where the steel grating needs to be manually positioned by operators during processing when welding and assembling, thus reducing work efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a modular composite steel grating, including a frame, with a positioning mechanism on the inner wall of the frame to improve the working efficiency during steel grating processing. The positioning mechanism also includes a reinforcing mechanism. The positioning mechanism comprises multiple flat steel plates, the front and rear sides of which are fixedly connected to the front and rear sides of the inner wall of the frame. Multiple positioning grooves are provided on the left and right sides of the top wall of the frame. Multiple support beams are provided on the top of the frame, with the bottom left and right sides of the support beams engaging with the corresponding positioning grooves. Multiple mounting grooves are provided on the bottom of the support beams, with the tops of the flat steel plates in the mounting grooves engaging with their corresponding mounting grooves. A fixing groove is provided on the front side of the support beam, with reinforcing ribs slidably connected inside the fixing groove. The outer walls of the reinforcing ribs penetrate the interior of the frame and the flat steel plates. A splicing assembly is provided on the front side of the frame, and locking assemblies are provided on the left and right front ends of the frame.

[0006] The above technical solution facilitates the positioning of the support beams by aligning and engaging multiple support beams with positioning slots. Subsequently, the sliding of the reinforcing ribs connects the flat steel plate to the interior of the support beams, thereby fixing both and improving the positioning effect during assembly. At the same time, with the cooperation of splicing components and locking components, the steel grating can be assembled in modules, improving the flexibility of the steel grating.

[0007] As a further description of the above technical solution:

[0008] The reinforcing mechanism includes multiple base plates, the outer walls of which are respectively fixedly connected to the middle of the inner wall of the flat steel plate. Multiple polyurethane plates are fixedly connected to the top of the base plates, high-strength steel plates are fixedly connected to the top of the polyurethane plates, and carbon fiber plates are fixedly connected to the bottom of the base plates.

[0009] The above technical solution increases the thermal insulation and soundproofing effect of the structure by connecting multiple polyurethane panels. Subsequently, the connection of high-strength steel plates improves the tensile strength and toughness of the flat steel plates. At the same time, the combination with carbon fiber plates further enhances the strength of the structure, thereby extending the service life of the steel grating.

[0010] As a further description of the above technical solution:

[0011] The splicing assembly includes multiple connecting plates, the rear sides of which are fixedly connected to the front side of the frame. The rear side of the frame is provided with multiple connecting slots at equal intervals, and the front sides of the multiple connecting plates engage with the corresponding connecting slots.

[0012] The above technical solution enables the initial splicing of the steel grating to be completed through the engagement of the connecting plates and connecting grooves of multiple connecting plates.

[0013] As a further description of the above technical solution:

[0014] The locking assembly includes two locking plates. The rear ends of adjacent sides of the two locking plates are fixedly connected to the left and right front ends of the frame, respectively. Locking slots are provided on the left and right rear ends of the frame, and the front ends of adjacent sides of the two locking plates are respectively connected to the corresponding locking slots.

[0015] The above technical solution enables one end of the locking plate to lock with the corresponding locking groove when the locking plate rotates, thereby improving the stability of the connection.

[0016] As a further description of the above technical solution:

[0017] The reinforcing mechanism also includes a silicone sealant layer, the top wall of which is fixedly connected to the bottom of the carbon fiber plate.

[0018] The above technical solution effectively increases the sealing of the bottom of the flat steel plate and reduces the penetration of water vapor through the silicone sealant layer.

[0019] As a further description of the above technical solution:

[0020] The top of the carbon fiber plate has multiple honeycomb holes, all of which are equally spaced.

[0021] The above technical solution improves the toughness of the carbon fiber plate by connecting multiple honeycomb holes.

[0022] As a further description of the above technical solution:

[0023] The interiors of the multiple support beams and the multiple flat steel plates are slidably connected by corresponding reinforcing ribs, and the multiple support beams and the multiple flat steel plates form a rectangular grid structure.

[0024] The above technical solution improves the impact resistance of the steel grating and increases its strength after forming a rectangular grid structure.

[0025] As a further description of the above technical solution:

[0026] The tops of the multiple support beams are all trapezoidal, and the multiple flat steel plates are all arranged symmetrically at equal intervals.

[0027] The above technical solution enables the reduction of wear on the top of the support beam and extends its service life when the support beam is designed in a trapezoidal shape.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the opening of multiple positioning slots facilitates the positioning and installation of the support beam. After the support beam is engaged and fixed with the flat steel plate at the bottom, the connection and engagement of the reinforcing ribs completes the fixing operation between the flat steel plate and the support beam, thereby improving the positioning effect during assembly. At the same time, with the cooperation of the splicing components and locking components, the steel grating can complete modular assembly, improving the flexibility of the steel grating and avoiding a reduction in construction efficiency.

[0030] 2. In this utility model, the connection of multiple polyurethane panels enables the internal thermal insulation and soundproofing effect of the structure. Subsequently, the connection of high-strength steel plates improves the internal strength of the flat steel plates and increases the tensile strength and toughness. At the same time, the fixation of carbon fiber plates further improves the strength of the structure and extends the service life of the steel grating. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a modular composite steel grating, including a frame 1. A positioning mechanism 2 is provided on the inner wall of the frame 1 to improve the efficiency of steel grating processing. A reinforcing mechanism 3 is provided inside the positioning mechanism 2. The positioning mechanism 2 includes multiple flat steel plates 201, the front and rear sides of which are fixedly connected to the front and rear sides of the inner wall of the frame 1. Multiple positioning grooves 202 are provided on the left and right sides of the top wall of the frame 1, facilitating the engagement and positioning of support beams 203. Multiple support beams 203 are provided on the top of the frame 1, and the bottom left and right sides of the support beams 203 respectively engage with the corresponding positioning grooves 202. A reinforcement mechanism 3 is provided on the bottom of each support beam 203. Multiple mounting slots 204 are provided, and the support beam 203 is then fixed to the top of the corresponding flat steel plate 201 through the multiple mounting slots 204. The top of the multiple flat steel plates 201 is respectively engaged with the corresponding 204. The front side of the support beam 203 is provided with a fixing slot 206. Then, under the connection and sliding of the reinforcing rib 205, it can lock the flat steel plate 201 and the support beam 203. The inside of the fixing slot 206 is slidably connected with the reinforcing rib 205, which makes it more convenient to process and thus improves the construction efficiency. The outer wall of the reinforcing rib 205 penetrates the interior of the frame 1 and the flat steel plate 201 respectively. The front side of the frame 1 is provided with a splicing component 207, and the left and right front ends of the frame 1 are provided with locking components 208.

[0040] Specifically, the positioning mechanism 2 installed on the inner wall of frame 1 aims to improve the processing efficiency of the steel grating. The front and rear sides of the flat steel plate 201 are fixed to the front and rear sides of the inner wall of frame 1 to form a basic support structure. Multiple positioning slots 202 opened on the left and right sides of the top wall of frame 1 provide positioning interfaces for the installation of support beams 203, facilitating the quick engagement of support beams 203 into place. Multiple support beams 203 placed on the top of frame 1 engage with the positioning slots 202 on the left and right sides of their bottom to achieve initial positioning; multiple installation slots 204 opened at their bottom engage with the flat steel plate 201. The top engagement secures the support beam 203 to the flat steel plate 201, forming a stable processing platform. The fixing groove 206 on the front of the support beam 203 is used to install the reinforcing rib 205. The reinforcing rib 205 slides within the fixing groove 206, and its outer wall penetrates the frame 1 and the interior of the flat steel plate 201. Through the connection of the reinforcing rib 205, the flat steel plate 201 and the support beam 203 are locked together, enhancing the overall structural strength, thereby reducing installation and adjustment time, making processing operations more convenient, and effectively improving construction efficiency.

[0041] Reference Figure 1 and Figure 4 The splicing component 207 includes multiple connecting plates 2071, the rear sides of which are fixedly connected to the front side of the frame 1. The rear side of the frame 1 is provided with multiple connecting slots 2072 at equal intervals, and the front sides of the multiple connecting plates 2071 respectively engage with the corresponding connecting slots 2072. The locking component 208 includes two locking plates 2081, the rear ends of the adjacent sides of the two locking plates 2081 are fixedly connected to the left and right front ends of the frame 1. The rear ends of the left and right sides of the frame 1 are provided with locking slots 2082, and the front ends of the adjacent sides of the two locking plates 2081 respectively engage with the corresponding locking slots 2082.

[0042] Specifically, the connection between the connecting plate 2071 and the connecting groove 2072 enables the two steel gratings to be initially spliced ​​together, thus achieving a modular application. Subsequently, the locking plate 2081 is flipped to lock with the corresponding locking groove 2082, thereby ensuring the stability of the connection and facilitating subsequent welding work.

[0043] Reference Figure 1 , Figure 3 and Figure 5The reinforcing mechanism 3 includes multiple substrates 301, the outer walls of which are fixedly connected to the middle of the inner wall of the flat steel plate 201, thereby reinforcing the interior of the flat steel plate 201 through the connection of the substrates 301. Multiple polyurethane boards 302 are fixedly connected to the top of the substrates 301, and high-strength steel plates 303 are fixedly connected to the top of the polyurethane boards 302. The fixation of the polyurethane boards 302 improves the thermal insulation and sound insulation effect, reduces the impact of excessive external temperature changes on the internal structure, and improves the toughness of the top of the structure through the high-strength steel plates 303, thereby increasing the tensile strength. A carbon fiber plate 304 is fixedly connected to the bottom of the substrates 301. The fixation of the carbon fiber plate 304 improves the compressive strength of the bottom of the flat steel plate 201, thereby extending the service life of the flat steel plate 201. The reinforcing mechanism 3 also includes a silicone sealant layer 306, the top wall of which is fixedly connected to the bottom of the carbon fiber plate 304.

[0044] Specifically, in the reinforcing mechanism 3, multiple base plates 301 are fixed to the outer wall of the inner wall of the flat steel plate 201 as internal reinforcing components to enhance the structural strength of the flat steel plate 201. Multiple polyurethane panels 302 fixed to the top of the base plates 301 utilize their excellent thermal insulation and sound insulation properties to form a thermal and sound insulation barrier, reducing the impact of significant external temperature changes on the internal structure of the flat steel plate 201. The high-strength steel plate 303 connected to the top of the polyurethane panels 302, with its high strength characteristics, enhances the toughness of the top of the structure and strengthens its tensile strength, reducing deformation of the overall structure when subjected to tensile forces. In the event of deformation or damage, the carbon fiber plate 304 fixed to the bottom of the substrate 301, with its high strength and high modulus, effectively improves the compressive strength of the bottom of the flat steel plate 201, disperses and bears the pressure from the bottom, reduces the risk of damage caused by pressure, and thus extends the service life of the flat steel plate 201. In addition, the silicone sealant layer 306 in the reinforcing mechanism 3 is fixed to the bottom of the carbon fiber plate 304 on the top wall, which plays a sealing role, further protects the internal structure, and enhances the connection stability between various components, thereby improving the performance and durability of the flat steel plate 201 and the overall structure.

[0045] Reference Figure 1 , Figure 4 and Figure 5 The top of the carbon fiber plate 304 has multiple honeycomb holes 305, which are all equally spaced; the interiors of the multiple support beams 203 and the multiple flat steel plates 201 are slidably connected by corresponding reinforcing ribs 205, and the multiple support beams 203 and the multiple flat steel plates 201 form a rectangular grid structure; the tops of the multiple support beams 203 are all trapezoidal, and the multiple flat steel plates 201 are all symmetrically arranged at equal intervals;

[0046] Specifically, the opening of multiple honeycomb holes 305 improves the toughness of the carbon fiber plate 304 and reduces damage from external stress. The rectangular grid structure formed by multiple support beams 203 and multiple flat steel plates 201 improves the impact resistance of the steel grating. The trapezoidal design at the top of the multiple support beams 203 reduces damage to the top of the support beams 203.

[0047] Working principle: The positioning mechanism 2 on the inner wall of frame 1 improves the processing efficiency of the steel grating. Multiple positioning slots 202 on the left and right sides of the top wall of frame 1 provide positioning interfaces for the support beam 203. During installation, the left and right sides of the bottom of the support beam 203 engage with the corresponding positioning slots 202 to achieve rapid initial positioning. Multiple mounting slots 204 at the bottom of the support beam 203 engage with the top of the flat steel plate 201 to further fix the relative position of the support beam 203 and the flat steel plate 201. The reinforcing ribs 20 are slidably connected in the fixing slots 206 on the front side of the support beam 203. 5. Its outer wall penetrates the interior of the frame 1 and the flat steel plate 201. Through the sliding reinforcing rib 205, it is locked to the interior of the flat steel plate 201 and the support beam 203, completing the locking operation of the two and enhancing the overall structural stability. With the cooperation of the splicing component 207 and the locking component 208, the modular structure formed can be quickly assembled, reducing installation and adjustment time, improving positioning accuracy, simplifying the steel grating processing process, avoiding the problem of reduced efficiency caused by complex assembly during construction, and effectively improving the working efficiency and flexibility of steel grating processing.

[0048] Furthermore, the strengthening mechanism 3 enhances the performance of the steel grating through a multi-layer structure. Multiple polyurethane boards 302 connected to the top of the substrate 301 utilize their own heat insulation and sound insulation properties to form a heat insulation and sound insulation barrier, reducing the impact of large changes in external temperature on the interior of the steel grating. Subsequently, the high-strength steel plate 303 enhances the tensile performance of the top of the structure through its high toughness and high strength, making it less prone to deformation or breakage when subjected to tensile forces. The carbon fiber plate 304 fixed to the bottom of the substrate 301 enhances the compressive strength of the bottom of the flat steel plate 201 with its high strength and high modulus characteristics, effectively dispersing and bearing pressure, reducing the risk of damage under pressure, thereby extending the service life of the flat steel plate 201.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
