Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure lower ceiling transition layer, specifically relating to a clamp assembly for steel structure lower ceiling transition layer. Background Technology

[0002] The transfer layer is fixed to the I-beam by welding. This construction method was very common in past decoration projects, especially in industrial plants, large commercial spaces, and public buildings with high requirements for ceiling load-bearing capacity or complex structural forms. However, this method of fixing the transfer layer has many drawbacks: 1. Low construction efficiency: The welding process requires professional welders, and preparatory work such as cleaning and positioning of the workpieces must be carried out before welding. After welding, the quality of the weld seam must be checked. The whole process is complicated and time-consuming, which seriously affects the construction progress. For example, in large-scale building projects, a large number of transfer layer welding works can extend the construction cycle by several weeks. 2. Potential quality issues: Welding quality is greatly affected by factors such as the welder's skill level and the construction environment. If the weld is not strong, the connection between the transfer layer and the I-beam may loosen or even fall off during subsequent use. If the weld is excessive, it will cause local stress concentration in the steel, reduce the overall stability of the structure, and create potential safety hazards for the building. 3. Irregularity: After welding, the position and angle are difficult to adjust. Once the installation position deviates, or the transition layer needs to be adjusted due to equipment or other reasons, the removal and re-welding are difficult and costly, and may even damage the I-beam and the transition layer, resulting in material waste. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a clamp assembly for the conversion layer of the suspended ceiling under the steel structure, which addresses the shortcomings of the existing technology. This utility model has high construction efficiency and good safety performance.

[0004] This solution is achieved through the following technical measures: a clamp assembly for a steel structure ceiling transition layer, comprising two upper and lower arc-shaped clamp plates used in pairs. The lower arc-shaped clamp plate has a keel installation opening in the middle, and the upper arc-shaped clamp plate has two bolt installation holes located on both sides of the keel installation opening. The two arc-shaped clamp plates are fixedly connected by bolts installed in the two bolt installation holes. The lower arc-shaped clamp plate has a through hole for the two bolts to pass through.

[0005] Preferably, the keel located in the keel installation opening is a square tube, and a U-shaped clamp is provided on the outside of the square tube, with the lower ends of two bolts threadedly connected to the upper ends of the two sides of the U-shaped clamp respectively.

[0006] Preferably, the extension direction of the keel mounting opening is perpendicular to the axial center line of the arc-shaped clamp plate.

[0007] Preferably, the bolt mounting hole is an elongated hole arranged along the circumference of the arc-shaped clamp plate.

[0008] Preferably, the inner ends of the two arc-shaped clamping plates are respectively fitted to the upper and lower sides of the flange plate of the I-beam, and the outer ends of the two arc-shaped clamping plates are joined together.

[0009] Preferably, the outer ends of the two arc-shaped clamping plates are symmetrically provided with grooves.

[0010] Preferably, a flexible gasket is provided between the inner ends of the two arc-shaped clamping plates and the flange plate of the I-beam.

[0011] Preferably, the upper ends of the two bolts are threaded with locking nuts that mate with the upper arc-shaped clamp plate, and spring washers and flat washers are provided between the locking nuts and the arc-shaped clamp plate.

[0012] The beneficial effects of this utility model are: 1. This utility model eliminates the need for on-site welding, waiting for weld cooling, and flaw detection. Fixing can be completed simply by tightening the arc-shaped clamp plate with bolts. This reduces installation time by more than 60%, increases construction efficiency, significantly improves installation speed, and eliminates the need for professional welders. Ordinary workers can operate it after simple training, reducing reliance on specialized trades. 2. This utility model avoids quality problems such as weld cracking, slag inclusion, and porosity caused by welding. There is no need to worry about structural safety hazards caused by weld fatigue in the later stage. It reduces the risk from the source, avoids damage to the H-beam base material by high welding temperature, does not destroy the original mechanical properties of the steel, and ensures the stability of the structural load-bearing capacity. 3. In actual use, the position or angle of the arc-shaped clamp plate can be finely adjusted by loosening the bolts. Compared with the one-time molding of welding and fixing, this utility model can adapt to construction errors or design fine-tuning needs. If disassembly or replacement is required later, there is no need to cut it. It does not damage the I-beam and the arc-shaped clamp plate and can be reused.

[0013] It is evident that this utility model possesses substantial features and represents an advancement compared to existing technologies. Attached Figure Description

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method, in conjunction with its accompanying drawings, will be used to describe the solution.

[0023] A clamp assembly for a steel structure ceiling transition layer includes two paired arc-shaped clamp plates 5. The lower arc-shaped clamp plate 5 has a keel mounting opening 12 in its center, the extension direction of which is perpendicular to the axial centerline of the arc-shaped clamp plate 5. The upper arc-shaped clamp plate 5 has two bolt mounting holes 10 located on either side of the keel mounting opening 12. The bolt mounting holes 10 are elongated holes arranged circumferentially along the arc-shaped clamp plate 5, allowing for convenient adjustment of the position or angle of the upper arc-shaped clamp plate 5 during construction. The two arc-shaped clamp plates 5 are fixedly connected by bolts 2 installed in the two bolt mounting holes 10. The lower arc-shaped clamp plate 5 has through holes through which the two bolts 2 pass.

[0024] The keel 7 is placed inside the keel mounting opening 12 along its extension direction, making the keel 7 more stable. The keel 7 located inside the keel mounting opening 12 is a square tube, which is a hot-dip galvanized square tube, and serves as one of the load-bearing components for the connection. A U-shaped clamp 6 is provided on the outside of the square tube, which provides the initial clamping force for the entire connection structure. The lower ends of the two bolts 2 are threaded to the upper ends of the two sides of the U-shaped clamp 6, and the upper ends of the two bolts 2 are threaded to a locking nut 8 that mates with the upper arc-shaped clamp plate 5. A spring washer 3 and a flat washer 4 are provided between the locking nut 8 and the arc-shaped clamp plate 5. The spring washer 3 is used to prevent loosening, and the flat washer 4 is used to distribute the pressure of the bolts 2 to ensure the tightness of the connection. The locking nut 8 is used to achieve a tight connection of each component, completing the entire connection process.

[0025] The inner ends of the two arc-shaped clamping plates 5 respectively mate with the upper and lower sides of the flange plate of the I-beam 1, and a flexible gasket 9 is provided between the inner ends of the two arc-shaped clamping plates 5 and the flange plate of the I-beam 1. The outer ends of the two arc-shaped clamping plates 5 are joined together, and grooves 11 are symmetrically opened on the outer ends of the two arc-shaped clamping plates 5. The two arc-shaped clamping plates 5 cooperate to clamp the I-beam 1, and the flexible gasket 9 can increase the friction and avoid damage to the surface of the I-beam 1.

[0026] The clamp assembly for the lower ceiling transition layer of this steel structure has the following advantages: I. Construction efficiency: No welding work is required, eliminating a series of cumbersome procedures such as beveling before welding and operation during welding. Ordinary construction workers can operate it after simple training, which can improve construction efficiency by more than 60% and effectively shorten the construction period. II. Regarding project quality: It avoids defects such as weld porosity and slag inclusion that may occur during welding, eliminates structural safety hazards caused by welding quality problems from the source, and ensures the reliability of the connection nodes; The high temperature during welding will not alter the mechanical properties of the base material of I-beam 1, thus ensuring the original load-bearing capacity of I-beam 1 and making the overall mechanical properties of the structure more stable. III. Cost Control: This reduces reliance on professional welders and lowers labor costs; at the same time, it eliminates the need for investment in welding equipment, resulting in an overall cost reduction of approximately 30%. The clamp assembly of this utility model is reusable and can be used again in similar connection scenarios in subsequent modification or demolition projects, saving material costs. IV. Construction safety: This avoids potential safety accidents such as fires, explosions, and burns during welding operations, reduces safety risks at the construction site, and protects the lives of construction workers. No welding fumes are generated during the construction process, which improves the air quality at the construction site and is beneficial to the occupational health of construction workers. V. Post-maintenance: If adjustments or modifications to the conversion layer are required later, the position of the arc-shaped clamp plate 5 can be easily fine-tuned by loosening the bolts 2. Compared with the non-adjustability of welded connections, this utility model has greater flexibility.
