Description

Technical Field

[0001] This invention relates to the field of safety protection devices, specifically a safety protection steel structure device for beams. Background Technology

[0002] Steel structures are widely used in the construction industry due to their advantages such as convenient assembly, strong overall stability, and short construction period. During the assembly of steel structure roofs, workers need to walk on the steel beams. The current safety protection method is for workers to wear safety belts and then attach safety hooks from the safety belts to steel wire ropes. The steel wire ropes ensure the safety of workers working at heights. However, the steel wire ropes are fixed to the steel frame, which is then fixed to the steel beams with bolts. This fixing method is cumbersome in two ways. First, the installation of the steel frame is relatively complicated, requiring drilling holes in the steel beams to fix them with bolts, making the installation and dismantling of the steel frame inconvenient. Second, the bolt fixing is susceptible to loosening due to the complex construction environment on construction sites, which can lead to an unstable steel frame installation and compromise the safety of workers. Summary of the Invention

[0003] The purpose of this invention is to provide a safety protection steel structure device for beams to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A safety protection steel structure device for beams includes a steel frame device and an I-beam on which the steel frame device is installed. The steel frame device includes a steel frame, a mounting base plate, an L-shaped plate, a piston plate, a movable clamping block, a threaded rod, a connecting plate frame, and a connecting rod.

[0008] Preferably, the movable clamping block has a second adsorption cavity, a rubber ring is attached to the opening of the second adsorption cavity, and a second insertion hole is provided on the inner bottom surface of the second adsorption cavity. Connecting holes are symmetrically provided on the movable clamping block on both sides of the second insertion hole, and connecting posts are inserted into the connecting holes.

[0009] Preferably, a piston plate is also inserted into the second adsorption chamber, and one end of the U-shaped rod on the piston plate inserted into the second adsorption chamber passes through the second insertion hole and is inserted into the second adsorption chamber, while the other end is located outside the second adsorption chamber. In addition, the movable clamping block on the lower side of the first adsorption chamber is aligned vertically with the first adsorption chamber.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0013] 1. A mounting base plate is fixedly installed at the lower end of the steel frame. The traditional installation method of the steel frame can be changed by setting the mounting base plate and the movable clamping block. That is, a first suction cavity is opened on the mounting base plate and a second suction cavity is opened on the movable clamping block.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 5 The present invention provides a technical solution:

[0023] A safety protection steel structure device for beams includes a steel frame assembly and an I-beam 1 on which the steel frame assembly is installed. The steel frame assembly includes a steel frame 2, a mounting base plate 21, an L-shaped plate 3, a piston plate 4, a movable clamping block 5, a threaded rod 6, a connecting plate frame 7, and a connecting rod 8. The mounting base plate 21 is fixedly installed at the lower end of the steel frame 2. Two first adsorption cavities 22 are symmetrically opened on the lower end surface of the mounting base plate 21. A rubber pad 23 is pasted at the opening of the first adsorption cavity 22, and a first insertion hole 24 is opened on the inner top surface of the first adsorption cavity 22. A piston plate 4 is inserted into the first adsorption cavity 22, and a U-shaped rod 41 is welded to the piston plate 4 and inserted into the first adsorption cavity 22. One end of the U-shaped rod 41 in cavity 22 passes through the first insertion hole 24 and is inserted into the first adsorption cavity 22. The other end is located outside the first adsorption cavity 22, and a connecting frame is welded to its end. Side plates 25 are symmetrically welded to both ends of the mounting base plate 21. Threaded holes are opened on the side plates 25. A fixing plate 26 is welded to the side plate 25 below the threaded holes. A guide rod 27 is welded to the fixing plate 26. A connecting spring 28 and a ball head post 29 are sleeved on the guide rod 27. The two ends of the connecting spring 28 are respectively welded to the fixing plate 26 and the lower end face of the ball head post 29. A guide hole is opened at the lower end of the ball head post 29, that is, the guide rod 27 is inserted into the guide hole.

[0024] L-shaped plates 3 are symmetrically welded to both ends of the mounting base plate 21. An L-shaped hole 31 is opened in the middle of the L-shaped plate 3. Connecting posts 32 are symmetrically welded to both sides of the horizontal plate at the lower end of the L-shaped plate 3. A limit plate 33 is welded to the end of the horizontal plate away from the vertical plate on the L-shaped plate 3. A return spring 34 and a movable clamping block 5 are sleeved on the connecting post 32. The lower end of the return spring 34 is welded to the horizontal plate of the L-shaped plate 3. A second adsorption cavity is opened on the movable clamping block 5. A rubber ring 51 is pasted at the opening of the second adsorption cavity. A second insertion hole 52 is opened on the inner bottom surface of the second adsorption cavity. Connecting holes 53 are symmetrically opened on both sides of the movable clamping block 5. Connecting posts 32 are inserted into the connecting holes 53. The upper end of the return spring 34 is welded to the lower end surface of the movable clamping block 5.

[0025] A piston plate 4 is also inserted into the second adsorption chamber, and one end of the U-shaped rod 41 on the piston plate 4 inserted into the second adsorption chamber passes through the second insertion hole 52 and is inserted into the second adsorption chamber, while the other end is located outside the second adsorption chamber. In addition, the movable clamping block 5 on the lower side of the first adsorption chamber 22 is aligned vertically with the first adsorption chamber 22.

[0026] The threaded rod 6 is threaded into the threaded hole, and an operating plate 61 is fixedly installed at one end of the threaded rod 6. A U-shaped groove 62 is opened on the circumference of the operating plate 61, and a conical block 63 is welded to one end of the operating plate 61 near the side plate 25. The other end of the threaded rod 6 is connected to the connecting plate frame 7, and a bearing hole 71 is opened in the middle of the connecting plate frame 7. A bearing is installed in the bearing hole 71, and the bearing is fitted with the threaded rod 6. The upper and lower ends of the connecting plate frame 7 are symmetrically hinged with connecting rods 8. The other ends of the connecting rods 8 are respectively hinged to the connecting frames on the upper and lower U-shaped rods 41. In addition, the width of the U-shaped groove 62 is equal to the diameter of the ball head column 29, and the ball head column 29 is inserted into the U-shaped groove 62 when the steel frame 2 is fixed.

[0027] When fixing the steel frame 2, pull the movable clamping block 5 down so that its lower end face contacts the limiting plate 33. Then, it can be installed on the I-beam 1, so that the lower end face of the mounting base plate 21 contacts the upper end face of the upper flange of the I-beam 1. At this time, the rubber pad 23 is in close contact with the upper end face of the upper flange, so that the first adsorption chamber 22 is in a sealed state. Then, the upper end face of the movable clamping block 5 is in close contact with the lower end face of the upper flange, so that the second adsorption chamber is also in a sealed state. In this state, the return spring 34 is compressed, allowing the movable clamping block 5 and the mounting base plate 21 to tightly clamp the I-beam 1. Then, the threaded rod 6 can be rotated to move under the action of the thread, causing the connecting plate frame 7 to move away from the side plate 25. This, under the action of the connecting rod 8, drives the piston plate 4 inserted in the first adsorption chamber 22 upwards and simultaneously drives the piston plate 4 inserted in the second adsorption chamber downwards. This creates a negative pressure in both the first and second adsorption chambers, thus firmly fixing the movable clamping block 5 and the mounting base plate 21 to the I-beam 1, achieving the fixed installation of the steel frame 2. During the movement of the threaded rod 6, the ball head column 29 moves downwards under the action of the conical block 63 until the threaded rod 6 is in position. At this point, the U-shaped groove 62 reaches the position of the ball head column 29. Then, under the action of the connecting spring 28, the ball head column 29 is ejected upwards into the U-shaped groove 62, fixing the threaded rod 6 and preventing it from rotating, thereby ensuring... The stability of the negative pressure allows the steel frame 2 to be firmly installed on the I-beam 1. In addition, the rubber pad 23 and rubber ring 51 ensure that the mounting base plate 21 and the movable clamping block 5 are tightly fitted with the upper flange, ensuring sealing while increasing friction. When the steel frame 2 needs to be disassembled, press the ball head column 29 down to make it exit the U-shaped groove 62, and then rotate the threaded rod 6 to drive the piston plate 4 to move in the opposite direction, so that the negative pressure disappears. The operation is simple and convenient, and the steel frame 2 is easy to install and disassemble, and is firmly installed.
