What Are the Transportation Fixing Methods for Ultra-Thin UHPC Panels (≤20mm)?

The transport and securing of ultra-thin UHPC panels (≤20mm) must follow the principles of "deformation prevention, breakage prevention, and slippage prevention," with the core approach of "specialized racks + flexible securing + zoned support." Through customized transport solutions, Qinglong has reduced the transport breakage rate of ultra-thin panels to 0.3%, with safe transport achieved for projects including the Shenzhen Yirui Biotechnology Building and the Meixihu Boston MIZU Salon.

I. Pre-Transport Preparation: Customized Specialized Racks

Specialized racks are the foundation of transport securing. Rack design: A steel structural frame (Q235B material) is used with internal layered partitions (spacing ≥100mm), and rubber pads (thickness ≥10mm) are attached to partition surfaces to prevent panel compression; Qinglong racks offer a layered load capacity ≥50kg/㎡ with deformation ≤1mm. Panel pre-treatment: Ultra-thin UHPC panels are covered with PE protective film (thickness ≥0.1mm), and edges and corners are fitted with anti-collision strips (thickness ≥20mm); Qinglong anti-collision strips are made of foam plastic with a wrapping coverage ≥50mm. Classified placement: Panels are arranged by size specification, with panels of the same specification stacked in ≤3 layers and rubber pads (thickness ≥5mm) placed between layers; Qinglong strictly prohibits mixing panels of different specifications to avoid uneven loading.

II. Securing During Transport: Flexible Restraint Against Slippage

Securing during transport prevents panel displacement and breakage. Flexible securing: Nylon slings or strapping bands (width ≥50mm) are used for horizontal binding at intervals ≤800mm, with moderate binding force (based on panels not slipping); Qinglong strictly prohibits direct binding with steel wire ropes to prevent surface crush damage. Vehicle selection: Flatbed trucks are used (cargo bed flatness ≤2mm/m) with rubber pads laid on the cargo bed floor; Qinglong transport vehicles are equipped with shock-absorbing devices to reduce bump impact. Transport speed: Speed is ≤40km/h on urban roads and ≤80km/h on highways, slowing down when turning or braking; Qinglong transport drivers are professionally trained and familiar with ultra-thin panel transport precautions.

III. Loading/Unloading and On-Site Securing: Full-Process Protection Without Damage

Loading/unloading and on-site storage prevent secondary damage. Loading/unloading method: Vacuum suction lifters (suction force ≥0.1MPa) or forklifts (equipped with special fork covers) are used; direct manual handling is prohibited. Qinglong vacuum suction lifters have a suction area ≥30% of the panel area, ensuring smooth lifting. On-site storage: The storage area is flat and solid, panels are elevated ≥300mm off the ground and covered with rainproof tarpaulins; Qinglong on-site storage areas are equipped with sunshade canopies to avoid exposure to sun and rain. Temporary securing: After transport to the site, panels are immediately installed or temporarily secured on specialized racks at a rack tilt angle ≤15°; Qinglong temporary securing uses snap-fit connections, leaving no risk of panel slippage. Project cases: The 4mm ultra-thin UHPC panels of the Meixihu Boston MIZU Salon used customized steel structural racks + vacuum suction lifting, achieving a transport breakage rate of 0; the 15mm ultra-thin UHPC panels of the Shenzhen Yirui Biotechnology Building used layered support + flexible binding during transport, with no deformation or breakage after installation.
