Description

Technical Field

[0001] The utility model relates to the field of protective devices in the process of steel structure assembly, in particular to a steel structure engineering protective bracket. Background Art

[0002] During the assembly process of steel structures, protective brackets are required to protect the edge openings to ensure the safety of construction.

[0003] In the prior art, cable ties or thin iron wires are generally used to tie the protective bracket between two adjacent steel structures. This type of fixing method has the problem of loose connection. The thin iron wires and cable ties are prone to rust, breakage or loosening, which causes the protective bracket to loosen or even fall off. The stability of the protective bracket cannot be guaranteed for a long time, but increases the safety risk. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 to Figure 4 In an embodiment of the utility model, a steel structure engineering protection bracket includes a protection frame 1, which is located between two adjacent steel structures. Limiting ears 3 are welded at the four corners of one side of the protection frame 1. The inner wall of the limiting ear 3 is slidably connected with a clamping mechanism connected to the steel structure. The top and bottom ends of the protection frame 1 are provided with a rotating mechanism for driving the clamping mechanism to move. The protection frame 1 is a hollow circular structure, and a protection rod 2 is welded between the upper and lower ends of the square inner wall of the protection frame 1. There are multiple protection rods 2, and the multiple protection rods 2 are equidistantly distributed along the length direction of the protection frame 1.

[0020] In this embodiment: during the construction of the steel structure, there is an adjacent opening (i.e., the space between two adjacent steel structures), and a protective bracket needs to be placed at the adjacent opening to ensure safety during the construction process. The protective bracket composed of the protective frame 1 and the protective rod 2 is placed between two adjacent steel structures, and then the rotating mechanism is rotated to drive the clamping mechanism to slide laterally along the inner wall of the limit ear 3. At this time, the left and right groups of clamping mechanisms move away from each other until the end of the clamping mechanism passes over the steel structure, and then the rotating mechanism is rotated in the opposite direction. At this time, the left and right groups of clamping mechanisms move toward each other until the left and right groups of clamping mechanisms clamp the two adjacent steel structures respectively. This installation method is very firm and does not require the use of cable ties for fixing, thereby further improving safety.

[0021] Please refer to Figure 3 and Figure 4 The clamping mechanism includes a sliding rod 4 slidably connected to the inner wall of the limiting ear 3, the sliding rod 4 extends along the length direction of the protective frame 1, a clamping plate 5 is welded to one end of the sliding rod 4, and a connecting rod 6 is integrally formed at the other end of the sliding rod 4. The inner wall of the limiting ear 3 is consistent with the outer wall of the sliding rod 4, and the cross-section of the clamping plate 5 is an "L"-shaped structure.

[0022] In this embodiment: a wrench is used to connect with the rotating mechanism and drive the rotating mechanism to rotate. At this time, the rotating mechanism drives the connecting rod 6 to slide, and the sliding connecting rod 6 drives the sliding rod 4 connected to it to slide along the inner wall of the limiting ear 3 until the horizontal plate portion of the clamping plate 5 passes over the steel structure, and then the rotating mechanism is rotated in the opposite direction. At this time, the horizontal plate portion of the clamping plate 5 is stuck between the wing plates of the steel structure until the vertical plate portion of the clamping plate 5 rests against the general end of the steel structure. The left and right clamping plates 5 respectively apply inward pulling force to the two steel structures, thereby achieving a clamping effect.

[0023] Please refer to Figure 1 , 2and 3, the two connecting rods 6 at the top extend from one end of the sliding rod 4 to the top end of the protective frame 1, the two connecting rods 6 at the bottom extend from one end of the sliding rod 4 to the bottom end of the protective frame 1, the vertical section of the two connecting rods 6 at the top is an open "C"-shaped structure facing downward, and the vertical section of the two connecting rods 6 at the bottom is an open "C"-shaped structure facing upward.

[0024] In this embodiment: this design method can achieve sliding connection between one end of the connecting rod 6 and the protective frame 1.

[0025] Please refer to Figure 3 and Figure 4 The rotating mechanism includes a slide groove 7 opened at the top and bottom ends of the protective frame 1, and a threaded rod 9 is rotatably installed on the inner wall of the slide groove 7. One end of the threaded rod 9 passes through the outside of the protective frame 1, and the threaded rod 9 is located outside the protective frame 1 and is integrally formed with a hexagonal end 10. The rotating mechanism also includes a slider 8 integrally formed at the end of the connecting rod 6. The slider 8 is slidably connected to the inner wall of the slide groove 7, and the inner wall of the slider 8 is formed with an internal threaded hole 11 threadedly connected to the threaded rod 9.

[0026] In this embodiment: a wrench is used to connect the hexagonal end 10, and then the wrench is rotated, the wrench drives the hexagonal end 10 to rotate, and the rotating hexagonal end 10 drives the threaded rod 9 to rotate. At this time, since the slider 8 cannot rotate, the slider 8 slides axially along the slide groove 7 under the action of the internal threaded hole 11.

[0027] It should be noted that there is a certain space between the hexagonal end 10 and the steel structure, so as to avoid the problem that the wrench cannot be effectively connected with the hexagonal end 10.

[0028] Please refer to Figure 4 The vertical cross-sections of the slide groove 7 and the slider 8 are both in a "convex" shape.

[0029] In this embodiment, this design can effectively prevent the slider 8 from being separated from the slide groove 7 and ensure that the slider 8 always slides in the slide groove 7.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
