Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel grating technology, specifically to a steel grating with irregular edges. Background Technology
[0002] Steel grating, also known as mesh grating, is a material made of multiple sets of flat steel bars arranged in a cross pattern and welded together. The interior of the plate forms several grids of the same size, which does not affect the supporting strength of the plate. Because the internal mesh facilitates water drainage, it is mostly used to cover the surface of ditches or to fix the plates in articulated bridges.
[0003] Although steel grating is relatively hard, most of its edges are polished smooth, and it lacks connecting structures during assembly. It is easily loosened by external vibrations, and its stability after assembly is greatly reduced. Walking on steel grating is also quite unsafe.
[0004] Now, a new type of irregular edge steel grating is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an irregular edge steel grating to solve the problem of poor connection stability mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an irregular edge steel grating, comprising a grating plate, an upper frame fixedly connected to the top of the grating plate, a right frame fixedly connected to the right side of the grating plate, a lower frame fixedly connected to the bottom of the grating plate, and a left frame fixedly connected to the left side of the grating plate. A rectangular groove is provided inside the grating plate. An outer frame one is fixed to the outer side of both the upper frame and the left frame, and protrusions are arranged on the surface of the outer frame one. An outer frame two is fixed to the inside of both the lower frame and the left frame, and a partition is fixed to the inside of the outer frame two, with grooves formed between the partitions.
[0007] As a further technical solution of this utility model, the protrusion is embedded in the groove, and the shape of the protrusion matches the inner wall of the groove.
[0008] As a further technical solution of this utility model, the outer frame one and the outer frame two have the same specifications, and the groove can accommodate the entry and exit of the protrusion.
[0009] As a further technical solution of this utility model, the surfaces of the upper frame, right frame, lower frame and left frame are all provided with slots, and rubber sleeves are fixed inside the slots.
[0010] As a further technical solution of this utility model, the ends of the steel strips on the top, bottom, left and right sides of the grid plate are all embedded in the slots, and the specifications of the edges of the steel strips of the grid plate match the inner wall of the rubber sleeve.
[0011] As a further technical solution of this utility model, the upper frame, right frame, lower frame and left frame are of the same length, and the number of slots and rubber sleeves is the same as the number of steel strip ends of the grid plate.
[0012] As a further technical solution of this utility model, the upper and lower frame sides and the upper and lower parts of the right and left frame are respectively provided with limiting grooves, and the limiting grooves are fixedly connected with plugs. The plugs are provided with two sets of screw holes II inside, and the limiting grooves are provided with screw holes I on the outer side. The screw holes I and II are threadedly connected with bolts, and patches are fixed in front of the two sets of limiting grooves.
[0013] As a further technical solution of this utility model, the inner walls of the screw hole one and screw hole two are matched with the bolt, and the two sets of limiting grooves are sleeved on the outside of the insert block.
[0014] Compared with the prior art, the beneficial effects of this utility model are: this irregular edge steel grating not only prevents adjacent steel gratings from falling apart and facilitates the assembly of grating accessories, but also maintains the stability of the frame. (1) By arranging protrusions on the surface of the outer frame one and fixing partitions inside the outer frame two, the steel gratings of each pair are spliced together. The protrusions on the surface of the outer frame one are aligned with the grooves inside each set of outer frame two. These grooves are formed by partitions arranged at equal intervals, which can accommodate the matching protrusions. The irregular edges increase the connection strength between the steel gratings and prevent them from loosening. (2) By providing slots on the surfaces of the top frame, right frame, bottom frame and left frame, the top frame, right frame, bottom frame and left frame are respectively fitted onto the four sides of the grid plate. The ends of the steel strips of the grid plate are embedded in the slots inside the top frame, right frame, bottom frame and left frame. The rubber sleeve inside the slot can restrict the grid plate from detaching from the surrounding fittings, making the steel grating easy to assemble and disassemble. The specifications of the top frame, right frame, bottom frame and left frame are the same and can be mixed and used. (3) By fixing the plugs between the limiting slots, after assembling the four sides, the top frame, the right frame, the bottom frame and the left frame, the adjacent top frame, the right frame, the bottom frame and the left frame form an L-shaped right angle limiting slot through the limiting slot. Insert the plugs into the limiting slots, align the screw hole one and the screw hole two and screw in the bolts to lock them. This can prevent the top frame, the right frame, the bottom frame and the left frame from loosening and improve the strength of the four reinforced grid plates. Attached Figure Description
