1. Mga Katangian ng High-Rise Members

Ang mga high-rise steel columns at beams ay may malalaking sections, makakapal na plates at kumplikadong connections, kadalasang gumagamit ng box columns, H-beam members at masalimuot na joints. Ang mga member na ito ay humihingi ng mas mataas na detailing accuracy, weld quality at dimensional tolerances kaysa sa ordinaryong planta, kaya kailangan ang mas kumpletong detailing at process preparation bago mag-fabrication.

2. Detailing at Segmentation

  • Connection detailing: beam-column joints, diaphragms, stiffeners at field connections na ni-check sa model stage;
  • Segmentation: paghahati ng columns at beams sa shipping/erection segments na may markadong splice positions at joints;
  • Trial assembly: isaalang-alang ang factory trial assembly para sa kumplikadong joints o sensitibong overall dimensions.

3. Mga Pangunahing Fabrication Controls

  • Cutting at assembly: thick-plate cutting, groove preparation at assembly accuracy;
  • Welding distortion: weld sequence, groove angles at countermeasures upang mabawasan ang post-weld straightening;
  • Diaphragms at stiffeners: assembly at welding sequence ng internal diaphragms sa box columns;
  • End preparation: column end milling o preparation upang matiyak ang field splice accuracy;
  • Dimensional inspection: critical dimensions, hole positions at straightness na sinusukat muli at itinatala ayon sa drawing.

4. Surface Treatment at Delivery

Ang mga member ay sini-shot blast at sina-coat ayon sa project requirements, may proteksyon at marking para sa makakapal na plates at espesyal na bahagi; ang mga segment ay sumusunod sa transport at lifting conditions, at ang aming pabrika sa Foshan ay propesyonal na nagpa-pack at nagpapadala sa pamamagitan ng barko. Ipadala ang inyong drawings at segmentation at connection requirements para sa review at quote ayon sa drawing.
