Temporary Steel Support

Temporary Steel Support  is a removable, short-term load-bearing structure made of steel, primarily used during construction, renovation, or maintenance to stabilize structures, bear temporary loads, or assist in component installation. Unlike permanent steel supports, it is dismantled after the main structure is completed or stable, serving as a critical safety guarantee in dynamic construction processes.

Core Characteristics

Temporary Load-Bearing

Designed to withstand short-term loads such as the weight of formwork, concrete, construction materials, or structural components during installation. Its load capacity is calculated based on temporary needs (e.g., 10–50 tons per unit) and is often adjustable to adapt to on-site changes.

Quick Assembly and Dismantling

Adopts modular designs (e.g., bolted connections, telescopic tubes) for rapid setup and removal, minimizing interference with subsequent construction steps. For example, in bridge construction, temporary steel supports can be installed in sections and disassembled after the beam is cured.

Flexible Adaptability

Adjustable Length/Height: Many models feature telescopic tubes or jacks to fine-tune height, accommodating uneven ground or varying structural elevations.

Modular Combination: Can be combined with cross-braces, diagonal supports, or base plates to form stable systems for complex scenarios (e.g., irregular building shapes).

Reusability

Made of high-strength steel (e.g., Q235, Q355), it is durable enough for repeated use across multiple projects, reducing material waste and costs. Surface treatments like painting or galvanizing extend its service life in harsh environments.

Common Types

Telescopic Steel Props: Vertical supports with inner and outer tubes, adjusted via pins or threads, widely used in formwork support for floors, walls, or columns.

Steel Frame Supports: Assembled from steel beams and columns, forming rigid frames to support large-span structures (e.g., roof trusses during installation).

Hydraulic Temporary Supports: Equipped with hydraulic jacks for precise load control, used in heavy lifting (e.g., installing precast concrete segments).

Shoring Towers: Multi-legged lattice structures (e.g., scaffolding-style) for supporting large areas like stadium roofs or industrial ceilings.

Typical Applications

Formwork Support: Holds concrete formwork in place during pouring and curing, preventing deformation until the concrete reaches sufficient strength.

Structural Stabilization: Supports unstable walls, beams, or foundations during renovation or demolition to prevent collapse.

Component Installation: Assists in positioning heavy elements (e.g., steel beams, precast panels, or bridge girders) during lifting and alignment.

Underground Engineering: Stabilizes tunnel faces, excavation slopes, or pit walls during mining, subway, or pipeline construction.

Disaster Relief: Quickly erected to shore up damaged buildings or create temporary passageways after earthquakes, floods, or storms.

Design and Safety Considerations

Load Calculation: Must account for static loads (e.g., material weight) and dynamic loads (e.g., worker movement, wind) to avoid overloading.

Stability Checks: Ensures resistance to lateral forces (e.g., wind, vibration) via diagonal bracing or weighted bases to prevent tipping.

Inspection and Maintenance: Regular checks for steel deformation, weld cracks, or loose connections during use; rusted parts should be treated promptly to maintain strength.

Compliance with Standards: Follows guidelines such as EN 12811 (scaffolding), AISC 360 (steel structures), or GB 51210 (temporary supports) to ensure safety.

In summary, temporary steel support is a versatile and essential tool in construction, bridging the gap between structural stages and ensuring safety during dynamic building processes. Its combination of strength, flexibility, and reusability makes it indispensable for efficient and secure construction operations.
