Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, and specifically to a steel grating with a reinforced structure. Background Technology

[0002] Steel grating is an open steel structure made by orthogonally combining load-bearing flat steel bars and crossbars at certain intervals and fixing them by welding or press-locking. Steel grating is mainly used for steel structure platform panels, trench covers, stair treads, and building ceilings. In existing steel gratings, the crossbars and flat steel bars are welded together, but after prolonged use, they deform and loosen, causing the entire grating to sag. Over time, the stress on the flat steel bars and crossbars increases, and the reduced support after loosening increases the likelihood of breakage, significantly shortening the service life of the steel grating. Therefore, to address these problems, a steel grating with a reinforced structure is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a steel grating with a reinforced structure to solve the problems mentioned in the background.

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: a steel grating with a reinforced structure, comprising a steel frame, wherein a plurality of first flat steels and a plurality of second flat steels are respectively provided in the steel frame, and a first steel wire rope is inserted into the first flat steel for fixed connection, and a second steel wire rope is inserted into the second flat steel for fixed connection. Limiting pads are installed at the connection points of the first flat steel and the first steel wire rope, and at the connection points of the second flat steel and the second steel wire rope, respectively, for fixed connection. The first steel wire rope and the second steel wire rope are in a cross shape. Support blocks are fixedly connected to both ends of the first steel wire rope and the second steel wire rope, and the support blocks are slidably inserted into the side wall of the steel frame. A threaded rod is fixedly connected to the other end of the support block, and the threaded rod is rotatably inserted into a nut. A positioning ring is slidably inserted into one side of the nut, and the other end of the positioning ring is fixedly connected to the steel frame.

[0005] Preferably, the inner side of the steel frame sidewall is provided with a plurality of first insertion holes and second insertion holes, with the first insertion holes located inside the long wall of the steel frame and the second insertion holes located inside the wide wall.

[0006] Preferably, the upper part of the side wall of the steel frame is provided with a plurality of first openings and a plurality of second openings, and the first openings are connected to the first insertion hole, while the second openings are connected to the second insertion hole.

[0007] Preferably, the support blocks at both ends of the first wire rope are slidably connected by inserting into the first insertion hole, and the support blocks at both ends of the second wire rope are slidably connected by inserting into the second insertion hole.

[0008] Preferably, the threaded rod, nut, and positioning ring are respectively placed in the first insertion hole and the second insertion hole, and one end of the positioning ring is fixedly connected to the inner wall of both the first and second openings. The opening directions of the first and second openings are opposite. The nut can be rotated within both the first and second openings.

[0009] Preferably, the other end of the positioning ring block is provided with a T-shaped ring block portion, and a T-shaped ring groove portion is opened in one side of the nut component, and the T-shaped ring block portion is inserted into the T-shaped ring groove portion for rotatable connection. Wherein, after the threaded rod connected to the support block is inserted into the nut component, rotating the nut component can tighten the first and second steel wire ropes, thereby straightening the first and second flat steel bars.

[0010] Preferably, the first flat steel and the second flat steel are interlocked to form a cross shape, and the two ends of the first flat steel are connected to the long wall of the steel frame, while the two ends of the second flat steel are connected to the wide wall of the steel frame.

[0011] Preferably, the first wire rope and the second flat steel are in the same direction, and the second wire rope and the first flat steel are in the same direction.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model features multiple first flat steel bars and multiple second flat steel bars within a steel frame, with the first and second flat steel bars interlocking. A first steel wire rope is inserted into each of the first flat steel bars, and the connection between the first flat steel bars and the first steel wire rope is secured by a limiting pad. Similarly, a second steel wire rope is inserted into each of the second flat steel bars, and the connection between the second flat steel bars and the second steel wire rope is also secured by a limiting pad. Support blocks are provided at both ends of the first and second steel wire ropes, with a threaded rod at one end of each support block inserted into a nut. The first and second steel wire ropes are inserted into the first and second flat steel bars within the steel frame, respectively, and the tightness is adjusted using the nut and the threaded rod to prevent the entire steel grating from sinking, thus avoiding loosening after prolonged use and increasing support and service life.

[0013] The existing steel grating uses interlocking welding between the crossbars and flat bars. However, after prolonged use, these crossbars and flat bars can deform and loosen, causing the entire steel grating to sag. Over time, the stress on the flat bars and crossbars increases, and the loosening of the crossbars and flat bars reduces their supporting force. This increases the likelihood of the flat bars and crossbars breaking, significantly reducing the service life of the steel grating. Attached Figure Description

The threaded rod 7 is inserted into a nut 8 for rotatable connection. A positioning ring block 9 is slidably inserted into one side of the nut 8, and the other end of the positioning ring block 9 is fixedly connected inside the steel frame 1.

[0019] In this embodiment, a plurality of first insertion holes 101 and second insertion holes 103 are respectively provided on the inner side of the side wall of the steel frame 1, and the first insertion holes 101 are placed inside the long wall of the steel frame 1, while the second insertion holes 103 are placed inside the wide wall.

[0020] Furthermore, a plurality of first openings 102 and a plurality of second openings 104 are respectively provided on the upper side wall of the steel frame 1, and the first openings 102 are connected to the first insertion hole 101, while the second openings 104 are connected to the second insertion hole 103.

[0021] Furthermore, the support blocks 6 at both ends of the first wire rope 4 are slidably connected by inserting them into the first insertion hole 101, and the support blocks 6 at both ends of the second wire rope 5 are slidably connected by inserting them into the second insertion hole 103.

[0022] Furthermore, the threaded rod 7, the nut 8, and the positioning ring 9 are respectively placed inside the first insertion hole 101 and the second insertion hole 103, and one end of the positioning ring 9 is fixedly connected to the inner wall of both the first opening 102 and the second opening 104. Simultaneously, the opening directions of the first opening 102 and the second opening 104 are opposite. The nut 8 can be rotated within both the first opening 102 and the second opening 104.

[0023] Furthermore, the other end of the positioning ring block 9 is provided with a T-shaped ring block portion 901, and a T-shaped ring groove portion 801 is opened in one side of the nut part 8. At the same time, the T-shaped ring block portion 901 is inserted into the T-shaped ring groove portion 801 for rotatable connection.

[0024] Threaded rods 7 are connected to the support blocks 6 at both ends of the first wire rope 4 and the second wire rope 5. After the threaded rods 7 are inserted into the nut 8, rotating the nut 8 can tighten the first wire rope 4 and the second wire rope 5, so that the first flat steel 2 and the second flat steel 3 are straightened.

[0025] In this embodiment, the first flat steel 2 and the second flat steel 3 are interlocked to form a cross shape, and the two ends of the first flat steel 2 are connected to the long wall of the steel frame 1, while the two ends of the second flat steel 3 are connected to the wide wall of the steel frame 1.

[0026] Furthermore, the first wire rope 4 and the second flat steel 3 are in the same direction, and the second wire rope 5 and the first flat steel 2 are in the same direction.

[0027] Working principle: Multiple first flat steel bars 2 and multiple second flat steel bars 3 are respectively provided within the steel frame 1, and the first flat steel bars 2 and second flat steel bars 3 are interlocked to form a mesh structure. A first steel wire rope 4 is inserted into the multiple first flat steel bars 2, and the connection between the first flat steel bars 2 and the first steel wire rope 4 is fixed by a limiting pad 10. A second steel wire rope 5 is inserted into the multiple second flat steel bars 3, and the connection between the second flat steel bars 3 and the second steel wire rope 5 is also fixed by a limiting pad 10. Therefore, the first steel wire rope 4 and the second steel wire rope 5 will affect the stress on the first flat steel bars 2 and the second flat steel bars 3, respectively. The second flat steel 3 is inserted and fixedly connected, so the overall stress will increase. Support blocks 6 are provided at both ends of the first wire rope 4 and the second wire rope 5. The support blocks 6 are inserted into the inner wall of the steel frame 1 and slidably connected. The threaded rod 7 at one end of the support block 6 is inserted into the nut 8. When the nuts 8 at both ends are rotated, the first wire rope 4 and the second wire rope 5 can be tightened or loosened. Since the first wire rope 4 and the second wire rope 5 are respectively connected to the first flat steel 2 and the second flat steel 3, the first flat steel 2 and the second flat steel 3 are straightened after being tightened, which increases the bearing capacity of the entire steel grating and prevents the steel grating from sinking.
