Core Product Parameters and Manufacturing Processes

Cangzhou Bóbīn Trading Co., Ltd.'s beam clamps are crafted using high-strength Q235B/Q355B steel as the core material (customized based on beam dimensions and load requirements). The manufacturing process involves multiple precision steps, including CNC-controlled precision stamping, integrated bending and forming, high-frequency welding reinforcement, shot blasting for rust removal, and advanced anti-corrosion treatments such as electrophoretic rust prevention combined with spray coating or hot-dip galvanizing. The product’s structural design centers around a "main keel channel steel + adjustable threaded rod + non-slip clamp plate + locking bolt," making it suitable for beam heights ranging from 100mm to 800mm—though custom specifications exceeding 800mm are also available. The main keel channel steel comes in sizes ranging from #8 to #12, tailored to meet varying load-bearing needs. The threaded rods offer an adjustment range of ±50mm to ±100mm, while the locking bolts utilize high-strength M12-M16 screws. Overall, the clamps deliver exceptional holding accuracy, with a tolerance error of no more than ±2mm, ensuring a seamless fit against formwork panels.

Core Performance Advantages of the Product

Superior clamping stability: Leveraging the high rigidity of premium-grade steel (Q355B yield strength ≥355 MPa), the beam clamps deliver a rated clamping force of up to 8 kN to 15 kN, effectively withstanding the lateral pressure generated during concrete pouring—up to a maximum of 60 kN/m². This prevents formwork expansion and slurry leakage, ensuring precise dimensions of the formed beams with dimensional accuracy no greater than ±3 mm, far surpassing industry-standard requirements.

Wide-ranging and flexible adaptability: With its adjustable lead screw and interchangeable anti-slip clamping plates, the system can quickly accommodate various beam cross-sections, including rectangular beams, T-beams, and custom-shaped beams—eliminating the need for individually tailored fixtures for different beam specifications. A single set of fixtures can handle multiple construction scenarios, significantly reducing the cost of purchasing specialized construction equipment.

Install efficiently and save labor: Featuring a dual-fixing structure of "snap-in + bolt-lock," this system eliminates the need for complicated tools during installation. A team of two can assemble and secure a complete set of clamps in just 3 to 5 minutes—representing an efficiency improvement of over 60% compared to traditional steel pipe and timber bracing methods, significantly reducing the time required for formwork reinforcement.

Long-lasting weather and corrosion resistance: The surface is treated with electrophoretic rust prevention (film thickness ≥20μm) combined with powder coating (film thickness ≥60μm), or hot-dip galvanizing (zinc layer thickness ≥85μm), effectively resisting corrosion from cement slurry on construction sites, rainwater erosion, and the damaging effects of humid environments. Under typical construction conditions, its service life can reach 5 to 8 years, with the ability to be reused over 30 times, significantly reducing long-term usage costs.

Safe, convenient, and easy to operate: The edges of the main keel channel steel have been rounded to prevent construction workers from getting cut; the anti-slip pallet features built-in rubber pads that enhance friction with the formwork, effectively preventing clamp slippage. Additionally, the locking bolts are equipped with anti-loosening nuts, ensuring the clamps remain securely in place even during concrete pouring and vibration—thus meeting the safety requirements outlined in the "Code for Acceptance of Construction Quality of Concrete Structural Engineering" (GB50204-2015).

Applicable Fields

The Liang clamp, with its efficient and robust reinforcement performance and wide adaptability, is widely used in:

◆ Structural Construction of Building Components: Used for lateral reinforcement of concrete beam formwork during the construction of beams in residential buildings, commercial complexes, office towers, and other structures. It is suitable for various types of beams, including floor-level frame beams, secondary beams, and connecting beams, ensuring high-quality beam formation.

◆ Bridge Construction: In the construction of bridge girders—such as highway bridges, municipal bridges, and high-speed rail bridges—as well as box girders and T-beams—this serves as a core tool for formwork reinforcement, effectively resisting the immense lateral pressure generated during large-volume concrete placement, thereby ensuring precise dimensional accuracy of the bridge beam structures.

◆ Factory and Venue Construction: Providing stable and reliable formwork reinforcement support for the construction of large-span beams such as crane beams in industrial plants and roof beams in large venues, perfectly suited to meet the demands of pouring heavy-load beams.

◆ Municipal engineering construction: Used for rapid formwork reinforcement during the construction of urban underground utility tunnels, secondary lining beams for tunnels, and pedestrian overpass structures, among others—perfectly suited to challenging construction environments such as damp underground conditions and confined spaces.

◆ Prefabricated Building Construction: In the prefabrication process of concrete beams, these standardized reinforcement tools serve as formwork supports for precast beams, ensuring consistent beam dimensions while enhancing both the production efficiency and quality of prefabricated components.

Leveraging the company's comprehensive production and control system—spanning eight rigorous quality-checking processes from raw material inspection to finished product shipment—and a robust quality-tracing framework, Liang clamps consistently meet industry standards such as the "Safety Technical Specification for Formwork in Building Construction" (JGJ162-2008). Each batch of products comes with a detailed quality-testing report and an installation guide video, ensuring precise compatibility with diverse beam construction requirements. This ensures reliable support for efficient project execution and uncompromising quality assurance in both domestic and international engineering endeavors.
