Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a structure for enhancing the stability of a steel cross beam. Background Art

[0002] During the erection of a scaffold, openings such as sump wells and post-cast strips will be encountered. There is no standing point for the vertical poles of the scaffold, and it is necessary to rely on the steel cross beam for force transmission. However, the steel cross beam with a high web and a narrow flange has a relatively high center of gravity. If no measures are taken at the construction site, the steel cross beam is likely to topple due to external forces such as human and mechanical vibrations, posing a safety hazard. Content of the Utility Model

[0003] Aiming at the problem of poor anti-overturning ability of the steel cross beam in the prior art, the utility model provides a structure for enhancing the stability of the steel cross beam. The stable fixation of the steel cross beam in the lateral direction is realized through fasteners and steel pipes.

[0004] To solve the above technical problems, the technical solution of the utility model is as follows:

[0005] A structure for enhancing the stability of a steel cross beam includes a plurality of steel cross beams arranged in parallel, a steel pipe arranged above the plurality of steel cross beams and perpendicular to the plurality of steel cross beams, and a plurality of pairs of fasteners sleeved and fixed on the outer periphery of the steel pipe and abutted against the opposite sides of the steel cross beam.

[0006] Further, the fastener includes a first fastener and a second fastener. The first fastener is fixedly sleeved on the outer periphery of the steel pipe. The second fastener is connected to the first fastener. The second fastener abuts against the side surface of the steel cross beam. A pair of the second fasteners respectively abut against the opposite sides of the steel cross beam.

[0007] Further, the first fastener includes a first arc-shaped fastener and a first bolt. The first arc-shaped fastener includes a pair of semi-circular arc plates with one end hinged together and the other end being an opening and closing structure. The first bolt passes through the opening and closing ends of the pair of semi-circular arc plates to sleeved and clamp the pair of semi-circular arc plates on the outer periphery of the steel pipe.

[0008] Further, the structure of the second fastener is the same as that of the first fastener. The axial directions of the through holes enclosed by the pair of semi-circular arc plates of the second fastener and the through holes enclosed by the pair of semi-circular arc plates of the first fastener are perpendicular to each other.

[0009] Further, a scaffold is connected above the plurality of steel cross beams. The scaffold is any one of a load-bearing support scaffold and an operation scaffold.

[0010] Further, the frame body includes multiple vertically arranged vertical rods, a first horizontal connecting rod connected between two adjacent vertical rods and arranged parallel to the steel cross beam, and a second horizontal connecting rod connected between two adjacent vertical rods and arranged perpendicular to the steel cross beam.

[0011] Further, the lower part of the vertical rod is connected to the upper part of the steel cross beam through an anti-slip device, and multiple vertical rods are connected to the upper part of each steel cross beam.

[0012] Further, the steel beam is a steel cross beam.

[0013] Further, a hollow round tube is fixedly arranged above the positioning plate, and the vertical rod extends into the hollow round tube and is fixed together with the hollow round tube.

[0014] Further, there are multiple steel tubes, and the multiple steel tubes are arranged above the steel cross beam between two adjacent vertical rods.

[0018] 2. The structure for strengthening the stability of the steel cross beam provided by the present utility model has the upper wing plate of the steel cross beam connected to the lower part of the vertical rod of the frame body through an anti-slip device. The anti-slip device can reduce the tipping and sliding of the steel cross beam. Cooperating with the reinforcement effect of the steel tube and a pair of fasteners on the steel cross beam, the lateral stable fixation between adjacent steel cross beams is realized, enabling multiple mutually parallel steel cross beams to form a whole, and further ensuring that the steel cross beam is stable without tipping over or sliding, thereby effectively ensuring the structural stability of the frame body above the steel cross beam.

[0030] As Figure 1 shown, a structure for strengthening the stability of steel crossbeams includes multiple steel crossbeams 1, multiple steel pipes 2, and multiple pairs of fasteners 3; the steel crossbeam 1 can be any one of an I-beam, a box-shaped steel beam, or a C-shaped steel beam. In this embodiment, taking the steel crossbeam 1 as an I-beam as an example, the technical solution claimed in this application will be specifically introduced. Among them, multiple steel crossbeams 1 are parallel to each other, multiple steel pipes 2 are also parallel to each other, and the length direction of the steel pipes 2 is perpendicular to the length direction of the steel crossbeams 1; the steel pipes 2 are located above the upper flange 11 of the steel crossbeam 1. The fastener 3 is sleeved and fixed on the outer circumference of the steel pipe 2, and the fastener 3 abuts against the side surface of the upper flange 11 of the steel crossbeam 1, and a pair of fasteners 3 abuts against the opposite sides of the upper flange 11.

[0031] This structure for strengthening the stability of steel crossbeams can fix multiple steel crossbeams 1 along the direction perpendicular to the length direction of the steel crossbeams 1 by using the steel pipes 2 and the fasteners 3, which can improve the stability of multiple steel crossbeams 1, prevent the steel crossbeams 1 from tipping over, and improve the stability of the overall structure.

[0032] In some embodiments, the fastener 3 is specifically a cross fastener 3. As Figure 6As shown, the fastener 3 includes a first fastener 31 and a second fastener 32. The first fastener 31 is fixedly sleeved on the outer periphery of the steel pipe 2. The second fastener 32 is connected to the first fastener 31, and the second fastener 32 abuts against the side surface of the upper flange 11 of the steel cross beam 1. A pair of second fasteners 32 respectively abut against the opposite sides of the upper flange 11. The first fastener 31 includes a first arc-shaped fastener 311 and a first bolt 312. The first arc-shaped fastener 311 includes a pair of semi-circular plates with one end hinged together and the other end being an opening and closing structure. The first bolt 312 passes through the opening and closing ends of the pair of semi-circular plates to sleevingly clamp the pair of semi-circular plates on the outer periphery of the steel pipe 2. The second fastener 32 has the same structure as the first fastener 31. The axial directions of the through holes enclosed by the pair of semi-circular plates of the second fastener 32 and the through holes enclosed by the pair of semi-circular plates of the first fastener 31 are perpendicular to each other. This kind of fastener 3 can clamp steel pipes 2 of different sizes by the opening and closing of the pair of semi-circular plates and the locking of the first bolt 312. After the pair of semi-circular plates clamp the steel pipe 2, the first bolt 312 is used to lock the opening and closing structure of the arc-shaped fastener 3, ensuring the connection reliability between the steel pipe 2 and the first fastener 31. In an alternative embodiment, the fastener 3 can also adopt other structural forms. For example, the fastener 3 includes a first fastener 31 and a limiting block connected below the first fastener 31. The first fastener 31 is used to lock the steel pipe 2, and the limiting block is used to limit both sides of the steel cross beam 1.

[0033] Figure 2 Figs. -5 show a schematic structural diagram of this structure for strengthening the stability of the steel cross beam connected below the frame body 4. The frame body 4 is an integral structure connected above multiple steel cross beams 1. The frame body 4 can be any one of a load-bearing support scaffold and an operation scaffold. In some application scenarios, the steel cross beam 1 can also be used for stacking equipment, stacking turnover materials (such as wooden beams), stacking engineering entity materials (such as steel bars), etc.

[0034] As Figure 2 As shown in Figs. -5, the frame body 4 includes multiple vertically arranged upright rods 41 arranged in an array, a first horizontal connecting rod 42 connected between adjacent two upright rods 41 and arranged parallel to the steel cross beam 1, and a second horizontal connecting rod 43 connected between adjacent two upright rods 41 and arranged perpendicular to the steel cross beam 1. After the multiple upright rods 41, the multiple first horizontal connecting rods 42, and the multiple second horizontal connecting rods 43 are connected, a three-dimensional space frame structure of the frame body 4 is formed.

[0035] Below each vertical rod 41, it is connected to the upper side of the steel cross beam 1 through an anti-slip and anti-shift device 5. Multiple vertical rods 41 are connected to the upper side of each steel cross beam 1, and multiple vertical rods 41 on the same steel cross beam 1 are arranged at equal intervals. The upper wing plate 11 of the steel cross beam 1 is connected to the lower part of the vertical rod 41 of the frame body 4 through the anti-slip and anti-shift device 5. The anti-slip and anti-shift device 5 can reduce the tipping and sliding of the steel cross beam 1, and cooperate with the steel pipe 2 and a pair of fasteners 3 for the reinforcement of the steel cross beam 1, realizing the lateral stable fixation between adjacent steel cross beams 1, making multiple mutually parallel steel cross beams 1 form a whole, and further ensuring that the steel cross beam 1 is stable without tipping or sliding, thereby effectively guaranteeing the structural stability of the frame body 4 above the steel cross beam 1.

[0036] During actual construction, when encountering various terrains such as post-cast strips, sump wells, and air shafts, etc., the frame body 4 finds the landing points through the steel cross beam 1, and realizes the placement of the frame body 4 through the connection between the frame body 4 and the steel cross beam 1. At the same time, the anti-slip and anti-shift device 5 is connected to the upper wing plate 11 of the steel cross beam 1 to ensure the fixation between the frame body 4 and the steel cross beam 1, and a pair of fasteners 3 fixed on the same steel pipe 2 are arranged on both sides of the upper wing plate 11 of the steel cross beam 1. The tipping and sliding of the steel cross beam 1 are effectively prevented through the abutment of the pair of fasteners 3.

[0037] In summary, the structure for strengthening the stability of the steel cross beam provided by the embodiment of the present utility model uses the steel pipe 2 and the fasteners 3 to fix multiple steel cross beams 1 along the length direction perpendicular to the steel cross beam 1, which can improve the stability of multiple steel cross beams 1, prevent the steel cross beam 1 from tipping, and improve the stability of the overall structure.

[0038] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
