Load-Cov Kev Xav Tau Ntawm Kab Hlaub Phab Ntsa Main Ncej
Cov kab hlau rhuav- cov phab ntsa tseem ceeb yuav tsum hloov cov khoom tuag, cua thiab seismic mus rau cov qauv tseem ceeb yam tsis tau nqa hauv pem teb lossis lub ru tsev loads. Nyob rau hauv ntug dej hiav txwv Suav siab- nce siab raug cua daj cua dub siab tshaj 2.5 kPa thiab inter- zaj dab neeg drifts txwv rau li 1/200 nyob rau hauv JGJ 102-2003, framing cov tswv cuab xav tau siab nruj- rau qhov hnyav piv thiab cov ntsiab lus sib txuas. Aluminium mullions feem ntau xav tau qhov sib txawv ntawm qhov sib txawv lossis qhov hnyav dua los tswj kev deflection. Kev soj ntsuam los ntawm cov pej thuam siab dua 200 m hauv thaj chaw seismic qhia tias cov thermal sib txawv thiab kev txav mus rau sab nraud ntxiv qhov xav tau ntawm cov ncej thib ob.
Cov yam ntxwv zoo ntawm Kub-Rolled H-Beams
Kub- dov H-beams tsim rau GB/T 11263-2024 xa cov kev ua tau zoo uas xav tau los ntawm kev sib npaug flange-web geometry. Cov neeg tsim qauv feem ntau xaiv HM lossis HN series ntu-xws li HM300 × 200 × 8 × 12 (kwv yees . 55.8 kg / m) los yog sib dua HN300 × 150 profiles-vim parallel flanges muab siab dua seem modulus thiab lub sij hawm ntawm inertia ib chav tsev loj dua li 18} cov pa Cov ntaub ntawv cov ntaub ntawv qhia txog 15–40% cov ntaub ntawv khaws tseg piv rau cov laus kuv-nqaj lwm txoj hauv kev khaws cia lub peev xwm. Q355 qib muab qhov tsim nyog tawm los lub zog. Parallel flanges kuj yooj yim rau bolted thiab welded pob qij txha, ceev erection ib zaug pre-embedded anchors thiab cais coatings raug ntsia los txwv galvanic corrosion. Complementarykub-dip galvanized steel khoomtuaj yeem siv rau cladding thiab accessories qhov twg ntxiv kev tiv thaiv saum npoo yog xav tau.
Stability thiab Seismic Performance
Tib geometry txhim khu kev ruaj ntseg. Cov flanges dav nce rau sab -torsional nruj thiab txo buckling kev pheej hmoo nyob rau hauv cua los yog av qeeg lub sij hawm. Hauv nruab nrab - mus rau - thaj chaw siab seismic nyob rau hauv Tuam Tshoj sab hnub tuaj seaboard, qhov ductility ntawm kub- dov Q355 seem tso cai tswj lub zog dissipation los ntawm inter- zaj dab neeg drift yam tsis muaj kev puas tsuaj ntxov ntawm lub vev xaib - flange junction. Fabrication kam rau ua ntawm ± 2.0 hli ntawm qhov siab rau cov seem hauv qab 400 hli pab tiv thaiv kev ua tsis zoo nyob rau hauv kev sib koom ua ke-ntau yam tau lees paub los ntawm ntau-cov ntaub ntawv teeb tsa hauv tsev. Cov pob qij txha yooj yooj yim thiab cov txheej txheej sib cais kom haum rau qhov sib txawv txav thaum tiv thaiv lub substrate.
Tsim nyog rau High -Rise Applications
Cov yam ntxwv no ua rau H-beam thav duab zoo haum rau kev ua haujlwm siab- nce siab. Txo tus kheej- hnyav txo lub hauv paus loads thiab txhawb modular prefabrication ntawm cov vaj huam sib luag loj dua. Ua ke nrog kev sib khi thiab kev tso dej siab heev, cov tshuab tau ua kom pom ntau yam - xyoo caum durability nyob rau hauv ntub, ntsev-laden nroog ib puag ncig. Thaum xav tau kev tiv thaiv corrosion ntxiv,galvanized steel kauj thiab cov ntawv xaivmuab kev tiv thaiv sib xws rau cov khoom siv façade muaj feem xyuam.
Cov kauj ruam tom ntej rau Project Teams
Tshwj xeeb kub- dov H-beams rau GB/T 11263 thiab JGJ 102 cov qauv tam sim no muab cov ntaub ntawv sib npaug ntawm qhov tawv nqaij, kev lag luam thiab kev ua haujlwm zoo. Hu rau tus tsim qauv tsim nyog- cov khoom siv hlau rau cov khoom seem, daim ntawv pov thawj zeb thiab cov ntsiab lus galvanizing sib phim rau koj cov qauv cua thiab seismic.
