Kev piav qhia luv luv

Precision-fabricated steel portal ncej apex (ridge) kev twb kev txuas nrog bolted gusset daim hlau rau koom rafter khub ntawm lub ru tsev ncov. Match-drilled bolt qhov kom ceev, yuam kev-dawb qhov chaw sib sau ua ke ntawm portal ncej ru tsev.

Cov lus piav qhia ntxaws

Qhov kev sib txuas ntawm apex no yog qhov sib koom ua ke sab saum toj ntawm lub rooj sib tham, qhov twg ob lub rafters sib ntsib ntawm lub ru tsev ncov. Nws yog ib qho ntawm cov kev sib txuas tseem ceeb tshaj plaws nyob rau hauv tus ncej - lub apex muaj kev sib xyaw ua ke ntawm cov compression siab los ntawm lub ntiajteb txawj nqus loads, muaj peev xwm tension reversal nyob rau hauv cua uplift, thiab tseem ceeb dabtsi yog khoov yog hais tias tus ncej yog tsim raws li nruam. Qhov kev sib txuas qhia tau siv ob daim ntawv tuab ntsug gusset bolted rau ob lub rafter webs nrog 6 siab -lub zog bolts rau ib phaj (Qib 8.8 lossis 10.9, M20-M30). Cov gusset daim hlau yog laser- txiav los ntawm Q355B steel phaj txuam nrog cov khoom siv rafter, nrog rau lub qhov taub CNC-drilled rau ± 0.5mm kam rau ua. Txhua lub phaj khub yog sib tw-drilled ua ke hauv lub khw kom thaum lub erector aligns cov rafters ntawm qhov chaw, txhua lub bolt swb nyob rau hauv tsis muaj kev quab yuam los yog reaming. Cov rafter kawg yog precisely miter- txiav mus rau lub ru tsev suab (feem ntau yog 5℃mus rau 30℃) thiab tag nrho - nkag mus rau welded rau cov bearing daim hlau. Txhua welds undergo UT inspection per AWS D1.1. Kev npaj nto yog SA 2.5 txhaj tshuaj blasting ntxiv rau epoxy zinc -nplua nuj primer (60-80μm), nrog HDG muaj rau corrosive ib puag ncig. Peb muab lub sijhawm- kev sib hloov tsim kev suav rau apex sib koom ua ke ntawm AISC 360 lossis Eurocode 3, suav nrog kev txheeb xyuas pawg bolt (shear + nro + prying) thiab gusset phaj thaiv shear pov thawj. Qhov xwm txheej ntawm kev sib txuas apex - nruj, ib nrab nruj, lossis pinned - yog txiav txim siab los ntawm koj qhov kev txheeb xyuas cov qauv, thiab peb tsim raws li. Txhua lub apex sib dhos ships nrog cov khoom siv ntsia liaj qhov rooj thiab erection kos duab.

Yam khoom

Cov ntsiab lus muag khoom

Txoj kev sib txuas rau txoj cai thav duab: Peb phim lub apex tsim rau koj cov ncej tsom xam - nruj apex rau portal ncej stability, semi- nruj yog tias koj tus qauv tso nyiaj rau ib feem fixity, los yog pinned rau yooj yim - txhawb nqa rafter systems

Prying nkaus accounted rau: Gusset phaj thickness yog tsis xam - peb xam lub prying quab yuam nyob rau hauv lub bolts vim phaj dabtsi yog khoov thiab loj lub phaj kom prying nyob rau hauv kev tso cai txwv ib AISC 360 / EC3

Lub rooj sib txoos hauv khw: Raws li kev thov, peb sib sau ua ke ob lub rafters nrog cov phaj gusset hauv lub khw raws li kev sim ua kom haum, txheeb xyuas cov ntsia hlau sib dhos thiab miter haum-ua ntej pleev xim thiab xa khoom

Cov kev pab cuam erection ib ntus suav nrog: Drift pins thiab ob peb ntxiv bolts ntawm txhua qhov loj yog ntim nrog txhua lub rooj sib txoos apex - koj erector tsis tas yuav cov cuab yeej sib dhos sib cais

Kev xaiv hluav taws xob hluav taws xob: Yog tias koj lub tsev xav tau hluav taws kub - ntsuas kev sib txuas apex, peb tuaj yeem muab cov txheej txheem intumescent lossis board tiv thaiv hluav taws siv hauv - khw ua ntej xa khoom

Lub tuam txhab zoo

Kev sib txuas engineering suav nrog: Peb txheeb xyuas lub sijhawm apex, shear, thiab axial quab yuam los ntawm koj tus qauv thav duab thiab tsim cov gusset daim hlau, bolt pawg, thiab welds raws li - tsis yog los ntawm cov rooj generic

Match-drilling cog lus: Txhua gusset phaj khub yog clamped ua ke thiab drilled raws li ib tug nyob rau hauv peb CNC machining chaw - yog hais tias ib tug ntsia liaj qhov rooj tsis ua raws li ntawm qhov chaw, peb them tus nqi rework

Tag nrho cov portal thav duab muaj peev xwm: Peb feem ntau muab cov thav duab ua tiav - kab, rafters, hauv caug pob qij txha, thiab apex txuas - kom ntseeg tau tias txhua qhov kev sib tshuam yog lub Hoobkas- koom tes

Kev hloov pauv sai sai: Cov khoom siv portal thav duab (kem + rafters + kev sib txuas) nkoj hauv 15-20 hnub ua haujlwm los ntawm kev pom zoo hauv khw

Laser tracker dimensional control: Txhua lub apex sib dhos yog ntsuas tawm tsam lub khw kos duab tom qab tsim los xyuas kom meej lub miter lub kaum sab xis, lub qhov ntsia hlau qhov chaw, thiab tag nrho cov geometry

Cov lus nug nquag

Q1: Puas yog qhov kev sib txuas apex nruj (lub sijhawm- tawm tsam) lossis pinned?

A: Nws nyob ntawm koj tus qauv tsim qauv. Feem ntau cov portal thav duab siv ib qho nruj lossis ib nrab -rigid apex los txo cov rafter dabtsi yog khoov lub sijhawm. Lub bolted gusset phaj configuration qhia tau tsim raws li nruj (tag nrho lub sij hawm hloov los ntawm bolt nro-compression ob peb), semi-rigid (ib nrab lub sij hawm nrog paub rotational nruj), los yog pinned (shear nkaus xwb). Peb tsim qhov twg los xij koj qhov kev txheeb xyuas thav duab xav tau.

Q2: Koj ua li cas kom paub tseeb tias ob lub rafters ntsib ntawm lub ru tsev qhov tseeb ntawm qhov chaw?

A: Cov rafter kawg yog tshuab -miter- txiav hauv khw mus rau lub kaum sab xis (± 0.5℃). Thaum lub sij hawm sim ua ke (yog tias txiav txim), peb txheeb xyuas lub suab nrog lub tshuab ntsuas digital. Cov cim sib tw ntawm lub rafter kawg thiab gusset daim hlau coj tus erector. Thaum thawj bolts yog snug-tightened, lub geometry yog xauv rau hauv.

Q3: Lub apex kev twb kev txuas hloov nro (cua uplift)?

A: Yog. Nyob rau hauv cua uplift, lub apex tej zaum yuav muaj tension reversal - cov rafters xav rub sib nrug es thawb ua ke. Peb lub phaj gusset thiab ntsia liaj qhov rooj tsim nyiaj rau qhov no: cov bolts raug kuaj xyuas qhov nro + prying nyob rau hauv uplift, thiab lub phaj gusset tau txheeb xyuas qhov thaiv shear thiab nro rupture. Peb muab cov ntaub ntawv sib cais nyob rau hauv daim ntawv qhia txog kev sib txuas.

Q4: Yuav ua li cas yog tias kuv lub ru tsev hloov pauv thaum tsim kev tsim kho tom qab koj tau pib tsim?

A: Peb lees paub tias kev hloov pauv tsim tshwm sim. Yog hais tias lub suab hloov tau raug txheeb xyuas ua ntej cov rafters raug txiav, peb kho tsis tau nqi. Yog tias rafters twb tau txiav lawm, peb ntsuas qhov kev ua haujlwm rov ua dua thiab muab tus nqi thiab sijhawm cuam tshuam tam sim ntawd. Peb cov thawj tswj xyuas qhov project tswj qhib kev sib txuas lus thoob plaws hauv kev tsim los daws cov kev hloov pauv tau zoo.
