Description

Technical Field

[0001] This utility model belongs to the field of steel structure building technology and relates to a device for a simple temporary operating platform for H-shaped steel beams. Background Technology

[0002] Steel structures, as a type of building, are widely used due to their uniform structure, high strength, and good plasticity and toughness. With the rapid development of my country's industry, more and more large-span stadiums, high-rise buildings, and small and medium-sized buildings are using steel structures. H-beams are a frequently used profile in steel structure engineering. H-beam steel structures are usually fabricated in factories and installed on the construction site. There are two installation methods: bolted connection and welding. In the welding method, the welding of the butt weld of the H-beam flange is usually done by welding legs to the column to erect a scaffold platform as the welder's operating platform. However, this operating platform cannot be moved. When welding other H-beam flange butt welds, a new scaffold platform must be erected as a temporary operating platform, which is time-consuming and labor-intensive.

[0003] Chinese utility model patent CN202596144U discloses a movable and simple operating platform for H-beam steel butt joint installation, including a ladder hook section, a ladder body section, diagonal braces, and an operating platform. The ladder hook section, ladder body section, and operating platform are integrally formed from top to bottom. The ladder hook section is set to the right and is in the shape of a right angle ∩, with the slot opening slightly larger than the width of the upper flange of the H-beam. The ladder body section is welded together with symmetrically arranged front and rear vertical bars and horizontal crossbars evenly distributed from top to bottom. The operating platform extends horizontally to the left and is welded together with symmetrically arranged front and rear horizontal longitudinal bars and horizontal crossbars evenly distributed from left to right. A steel platform is welded onto the horizontal crossbars and horizontal longitudinal bars. Diagonal braces are welded between the front and rear vertical bars of the ladder body section and the front and rear horizontal longitudinal bars of the operating platform, forming a sturdy steel structure that can be reused, effectively improving welding efficiency and reducing construction costs.

[0004] However, in the aforementioned prior art, the operating platform is not fixedly connected to the H-shaped steel column. During use, the operating platform may shake, which could threaten the life safety of the workers. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a device for a simple temporary operating platform using H-shaped steel beams, which effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for a simple temporary operating platform for H-shaped steel beams includes a support frame. The left and right ends of the front and rear sides of the support frame are provided with a second connecting column and a first connecting column. The ends of the first connecting column and the second connecting column away from the frame are provided with clamp steel plates that are fixedly connected to the H-shaped steel beam.

[0007] Furthermore, a U-shaped groove is formed on the side surface of the fixture steel plate, and the fixture steel plate is inserted on the upper and lower flanges of the H-shaped steel beam through the U-shaped groove. The four fixture steel plates are arranged in a rectangular array, and a fixing component is arranged between the upper and lower fixture steel plates.

[0008] Furthermore, rectangular holes are symmetrically and penetratingly formed on the upper and lower flanges of the H-shaped steel beam. The fixing component includes fixing pin columns inserted on the upper and lower fixture steel plates. The lower end of the fixing pin column passes through the fixture steel plate and the rectangular hole and extends to the lower side of the lower fixture steel plate.

[0009] Furthermore, a fixing nut is threadedly connected to the lower end of the fixing pin column, and the upper side surface of the fixing nut contacts the lower side surface of the fixture steel plate.

[0010] Furthermore, a reinforcement sleeve is coated at the connection between the fixture steel plate and the first connecting column and the second connecting column.

[0011] Furthermore, the reinforcement sleeve includes two U-shaped steels symmetrically arranged up and down, and the side surfaces of the two U-shaped steels in contact are fixed by welding.

[0012] Furthermore, the support frame body includes a frame body in the shape of a "mouth". A transverse steel column is arranged inside the frame body, and a plurality of longitudinal steel columns fixedly connected to the inner side surface of the frame body are linearly arranged on the upper side surface of the transverse steel column.

[0013] Compared with the prior art, the utility model has the following beneficial effects: In the utility model, the four corners of the support frame body are fixedly connected to the H-shaped steel beam through the first connecting column, the second connecting column and the four fixture steel plates, further improving the stability and reliability of the support frame body during use and ensuring the safety of construction workers during use; In the utility model, the fixed connection between the upper and lower fixture steel plates and the H-shaped steel beam is realized through the fixing pin column and the fixing bolt, improving the connection strength between the fixture steel plate and the H-shaped steel beam.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model. Embodiment 1

[0017] As Figure 4 shown, a device for a simple temporary operation platform of an H-shaped steel beam includes a support frame body 2. Second connecting columns 10 are symmetrically arranged at the left ends of the front and rear sides of the support frame body 2. Fixture steel plates 5 fixedly connected to the H-shaped steel beam 1 are welded to the ends of the second connecting columns 10 far from the support frame body 2.

[0018] In this embodiment, a U-shaped groove is formed on the side surface of the fixture steel plate 5. The fixture steel plate 5 is inserted into the lower flange of the H-shaped steel beam 1 through the U-shaped groove, and a fixing component is arranged between the fixture steel plate 5 and the lower flange of the H-shaped steel beam 1.

[0019] In this embodiment, a rectangular hole 101 is formed through the lower flange of the H-shaped steel beam 1. The fixing component includes a fixing bolt 11 arranged on the fixture steel plate 5. The lower end of the fixing bolt 11 passes through the fixture steel plate 5 and the lower flange of the H-shaped steel beam 1 and extends to the lower side of the fixture steel plate 5; the lower end of the fixing pin 7 is threadedly connected with a fixing nut 8, and the upper side surface of the fixing nut 8 contacts the lower side surface of the fixture steel plate 5.

[0020] In this embodiment, the support frame body 2 includes a "mouth"-shaped frame body 2. A transverse steel column 3 is arranged inside the frame body 2, and a plurality of longitudinal steel columns 4 fixedly connected to the inner side surface of the frame body 2 are linearly arranged in an array on the upper side surface of the transverse steel column 3.

[0021] In the above embodiment, the support frame 2 is welded from L30*3 angle steel and 30*3 flat iron. The transverse steel column 3 and the longitudinal steel column 4 are both made of flat iron and are welded and fixed to each other. The spacing between adjacent longitudinal steel columns 4 is 100mm. The clamping steel plate 5 is a steel plate with a thickness of 10-14mm, a length of 250mm, and a width of 50mm. The U-shaped groove inside the clamping steel plate 5 is a rectangular groove of 20*100mm with the left side axis of the clamping steel plate 5 as the reference.

[0022] In the above embodiments, construction workers can pick up unwanted scrap steel on the construction site and splice and fix it by welding, which is simple, convenient, efficient and fast. In use, construction workers insert the U-shaped groove on the clamp steel plate 5 into the lower flange of the H-beam 1, and use the fixing bolts 11 and fixing nuts 8 to fasten the clamp steel plate 5 to the H-beam 1, thereby fixing the support frame 2. This allows construction workers to stand on the support frame 2 to weld and install high-strength bolts on the H-beam 1. The combined use of the clamp steel plate 5, fixing bolts 11, and fixing nuts 8 improves the connection strength between the support frame 2 and the H-beam 1, further ensuring the safety of construction workers during use. Meanwhile, construction workers can remove the fixing bolts 11 and 11 to adjust the position of the support frame 2 on the H-beam 1. After adjustment, the fixing bolts 11 and 11 are used again for fixed connection, which improves the flexibility of the device during use.

[0023] Example 2 differs from Example 1 in that: like Figure 1 as well as Figure 2 As shown, in this embodiment, the left and right ends of the front and rear sides of the support frame 2 are provided with a second connecting column 10 and a first connecting column 6. The ends of the first connecting column 6 and the second connecting column 10 away from the frame 2 are provided with clamping steel plates 5 that are fixedly connected to the H-shaped steel beam 1.

[0024] In this embodiment, the clamp steel plate 5 has a U-shaped groove on its side. The clamp steel plate 5 is inserted into the upper and lower flanges of the H-shaped steel beam 1 through the U-shaped groove. The four clamp steel plates 5 are arranged in a rectangular array, and a fixing component is provided between the upper and lower clamp steel plates 5.

[0025] In this embodiment, the upper and lower flanges of the H-shaped steel beam 1 are symmetrically provided with rectangular holes 101. The fixing component includes fixing pins 7 inserted into the upper and lower clamping steel plates 5. The lower end of the fixing pins 7 passes through the clamping steel plate 5 and the rectangular holes 101 and extends to the lower side of the clamping steel plate 5. The lower end of the fixing pins 7 is threaded with a fixing nut 8. The upper side of the fixing nut 8 contacts the lower side of the clamping steel plate 5.

[0026] like Figure 3 As shown, in this embodiment, the connection between the clamp steel plate 5 and the first connecting column 6 and the second connecting column 10 is covered with a reinforcing sleeve 9. The reinforcing sleeve 9 includes two U-shaped steels arranged symmetrically on the upper and lower sides, and the sides of the two U-shaped steels that are in contact are fixed by welding.

[0027] In the above embodiment, the first connecting column 6, the second connecting column 10, and the four clamping steel plates 5 fix the four corners of the support frame 2 to the H-shaped steel beam 1, which further improves the stability and reliability of the support frame 2 in use and ensures the safety of construction personnel in use. Meanwhile, the upper and lower clamping steel plates 5 are fixedly connected by fixing pins 7 and fixing bolts 11, which improves the connection strength between the clamping steel plates 5 and the H-shaped steel beam 1, and also improves the convenience for construction personnel to install and adjust the device. The clamping steel plate 5 is reinforced by a reinforcing sleeve 9 composed of two U-shaped steels arranged symmetrically at the top and bottom. This improves the connection strength between the clamping steel plate 5 and the first connecting column 6 and the second connecting column 10, prevents breakage between the clamping steel plate 5 and the first connecting column 6 and the second connecting column 10, and further improves the stability and reliability of the device.
