Muaj pes tsawg txoj kev sib txuas koj puas paub txog kab ko taw ntawm ntau lub tsev cog khoom?
Cov kab ke ko taw txuas ntawm lub tsev cog khoom multi-span yog ib qho ntawm cov nodes tseem ceeb. Muaj ntau txoj hauv kev sib txuas rau cov kab ke sib txuas ntawm ko taw, uas tau txiav txim siab los ntawm chav tsim tsim raws li yam xws li hom, qhov loj me, ntau yam loads, thiab kev coj ua ntawm chav tsev tsim.
1. Kev faib tawm ntawm kem ko taw kev sib txuas rau ntau lub tsev cog khoom
Raws li kev suav quab yuam, kab ke ko taw kev sib txuas ntawm ntau lub tsev cog khoom tau muab faib ua ob hom, xws li kev sib txuas nruj (sib sau ua ke) thiab pob khawm sib txuas. Qhov sib txawv ntawm ob yog: lub pob txha pob txha tuaj yeem ua tsis tau tsuas yog lub siab axial thiab kab rov tav shear quab yuam, tab sis kuj yog lub sijhawm khoov, lub pob khawm pob tsuas tuaj yeem dais lub axial siab thiab kab rov tav shear quab yuam, thiab kem tuaj yeem tig dawb, tab sis tsis tuaj yeem dais lub sijhawm khoov. Rau multi-span greenhouses nrog tib seem saum toj no lub hauv paus, lub hauv paus ntawm rigidly txuas kem ko taw yog loj tshaj lub hinged kem ko taw. Lub semi-rigid kev twb kev txuas yog nruab nrab ntawm ob, thiab nws tsis yog reflected nyob rau hauv tus tsim specifications, uas yog, theoretical lub hauv paus rau semi-rigid kev twb kev txuas nyob rau hauv kev tsim kho yog tsis heev mature, thiab kev lag luam tseem tsis tau mus txog qhov kev pom zoo.
2. Hom kev sib txuas ntawm ntau lub tsev cog khoom kem taw
①Cov kab txuas nrog cov ntsia liaj qhov rooj (cov hlau tiaj tus)
Txoj kev tsim kho yog tias muaj cov bolts pre-embedded (pav hlau) nyob rau sab saum toj ntawm lub hauv paus, thiab muaj qhov nruab nrab ntawm lub phaj hauv qab ntawm kem (cov hauv paus ntawm kem), uas tuaj yeem nruj nruj ntawm qhov chaw, uas yog txoj kev sib txuas feem ntau siv tam sim no. Raws li tus naj npawb ntawm embedded bolts, muaj cov hauv qab no:
(1) 1 pre-embedded ntsia liaj qhov rooj (qee yam siv pre-embedded ca steel)
(2) 2 embedded bolts (qee zaus siv 2 steel expansion bolts)
(3) 4 faus bolts (sib npaug rau semi-rigid txuas)
(4) 4 faus bolts thiab pre-embedded steel phaj nyob rau hauv ib tug
②On-site vuam ntawm kem thiab embedded steel phaj
Txoj kev tsim kho yog tias muaj pre-embedded steel daim hlau nyob rau sab saum toj ntawm lub hauv paus, tsis muaj pre-embedded bolts, qhov siab ntawm lub saum npoo ntawm pre-embedded steel daim hlau yog qhov siab ntawm hauv qab ntawm kem, pouring yog nyob rau hauv qhov chaw ntawm ib lub sij hawm, thiab cov phaj hauv qab ntawm kem thiab pre-embedded steel daim hlau yog welded rau ntawm qhov chaw.
③ Pre-embedded steel yeeb nkab
Nws yog feem ntau siv nyob rau hauv multi-span yas zaj duab xis tsev xog paj, thiab muaj tsawg yuav tsum tau rau qhov tseeb ntawm lub hauv paus kev tsim kho.
Txoj kev tsim kho yog: lub pre-embedded steel yeeb nkab yog tsim nyob rau tib lub sij hawm raws li lub hauv paus, pre-embedded steel yeeb nkab yog me ntsis loj dua lub cheeb ntawm lub kem, los yog tib yam li txoj kab uas hla ntawm kem, pre -embedded steel yeeb nkab yog txo nyob rau hauv txoj kab uas hla, thiab ntsia liaj qhov rooj qhov nyob rau hauv lub hauv paus ntawm lub kem thiab pre-embedded steel yeeb nkab. Bolt rau.
④Kem thiab lub hauv paus kev tsim kho
Txoj kev sib txuas no yog kev sib txuas ruaj khov, thiab txoj kev tsim kho yog los tsim cov kab ke thiab lub hauv paus tib lub sijhawm, thiab tom qab ntawd nruab lub gutter thiab lwm yam khoom siv tom qab kho kom muaj zog. Hom kev sib txuas no tsis yog siv dav, thiab feem ntau yog siv rau hauv ntau qhov yas zaj duab xis tsev cog khoom, uas muaj cov kev cai qis rau qhov tseeb ntawm kev tsim kho hauv paus.
