Fireproofing Methods rau Steel Structures

Steel qauv tsev yuav tsum tau siv kev tiv thaiv hluav taws kom cov tsev muaj qhov ntsuas hluav taws kub txaus. Tiv thaiv cov qauv hlau los ntawm kev kub ceev mus rau qhov kub thiab txias hauv qhov hluav taws kub, tiv thaiv kev deformation ntau dhau thiab txawm tias lub tsev tawg, yog li yeej lub sijhawm muaj txiaj ntsig rau kev tua hluav taws thiab kev nyab xeeb ntawm cov neeg ua haujlwm khiav tawm, thiab zam lossis txo qhov poob los ntawm hluav taws.

Kev tiv thaiv hluav taws kub rau cov qauv hlau tuaj yeem muab faib ua ob txoj hauv kev.

• Lub tsho tiv no thiab qhwv cov ntaub ntawv fireproof
• Concrete-filled steel tube tus tswv cuab

Lub tsho tiv no thiab qhwv cov ntaub ntawv fireproof

Thawj txoj kev yog lub tsho tiv no thiab qhwv cov khoom siv hluav taws xob rau saum npoo ntawm cov qauv hlau los tiv thaiv lossis thaiv qhov sib txawv thiab sib kis ntawm tshav kub mus rau cov khoom siv hauv paus, thiab txuas ntxiv qhov hluav taws kub txwv ntawm cov qauv hlau. Thawj hom kev tiv thaiv hluav taws kub rau cov qauv steel feem ntau suav nrog cov hauv qab no:

Siv cov xim hluav taws kub retardant

Txheej hluav taws kub retardant txheej: Hluav taws kub retardant txheej rau steel qauv hais txog ib yam ntawm cov khoom siv hluav taws xob uas tuaj yeem tsim cov hluav taws kub-resistant thiab kub-insulating tiv thaiv txheej tom qab tau coated rau saum npoo ntawm steel qauv thiab muab cov hluav taws-resistant kev ua tau zoo ntawm steel qauv. .

Nws yog lub teeb hauv qhov hnyav thiab yooj yim hauv kev tsim kho thiab haum rau cov khoom ntawm txhua yam duab thiab txoj haujlwm. Nws muaj cov thev naus laus zis paub tab thiab yog qhov siv dav tshaj plaws, tab sis nws muaj cov cai nruj me ntsis ntawm coated substrate thiab ib puag ncig.

Fireproof board npog

Fireproof board cladding: Fireproof board tiv thaiv tsis muaj siab xav tau ntawm ib puag ncig tej yam kev mob thiab steel puag nto, zoo zoo nkauj nyhuv, tiv thaiv kev sib tsoo, cuam tshuam hnav tsis kam, kev tsim kho tsis txwv los ntawm ib puag ncig tej yam kev mob, siab siv efficiency, tshwj xeeb tshaj yog haum rau kev sib tsoo. thiab tsis tso cai rau ntub kev tsim kho.

Outsourcing qhob

Outsourcing pob zeb masonry: pob zeb tuaj yeem yog pob zeb dav lossis aerated pob zeb. Cov txheej tiv thaiv muaj lub zog siab, thiab cuam tshuam tsis kam, thiab nyob hauv qhov chaw loj. Nws yog ib qho nyuaj rau kev tsim ntawm steel kab thiab kab pheeb ces kaum braces. Nws yog tsim rau kev sib tsoo yooj yim, tsis muaj hluav taws tiv thaiv los ntawm cov kab hlau rau cladding panels.

Npog nrog saj zawg zog xav insulating khoom

Saj zawg zog zoo li thermal rwb thaiv tsev cov ntaub ntawv txheej: zoo thermal rwb thaiv tsev, yooj yim siv, tsis tshua muaj nqi, haum rau sab hauv tsev qhov chaw uas tsis yooj yim puas los ntawm txhua yam kev puas tsuaj, thiab tiv thaiv los ntawm dej.

Composite tiv thaiv hluav taws

Kev tiv thaiv hluav taws sib xyaw: Kev tiv thaiv hluav taws sib xyaw suav nrog ob txoj hauv kev los npog cov xim tsis muaj hluav taws nrog hluav taws kub los yog cov khoom siv rwb thaiv tsev. Thaum siv cov kev tiv thaiv hluav taws sib xyaw, nws yuav tsum tau ua kom ntseeg tau tias kev tsim kho ntawm cov khoom siv sab nrauv tsis ua rau cov qauv kev puas tsuaj lossis kev puas tsuaj rau cov txheej txheem tiv thaiv hluav taws.

Lub pob zeb ua kom puv steel tube

Qhov thib ob txoj kev yog ncuav cov ntaub ntawv xws li kua los yog tov av nyob rau hauv lub steel yeeb nkab kom nqus cua sov los ntawm cov hlau substrate nyob rau hauv lub sij hawm kom lub kub ntawm steel nce maj mam thiab prolongs lub sij hawm rau cov hlau kom sov mus rau qhov tseem ceeb kub.

Cov tswv cuab ntawm cov pob zeb ua pob zeb yog hais txog cov tswv cuab tsim los ntawm kev sau lub voj voog lossis lub voj voos hlau nrog cov pob zeb, thiab cov raj hlau thiab cov pob zeb ua ke tau sib koom ua ke hauv tag nrho cov haujlwm hauv kev thauj khoom. Thaum muaj hluav taws kub, cov pob zeb tseem ceeb ntawm cov yeeb nkab steel muaj lub luag haujlwm ntawm kev nqus cov cua sov ntawm qhov chaw ntawm cov yeeb nkab steel.

Tsis siv neeg sprinklers tuaj yeem tsis tsuas yog tua hluav taws, tab sis kuj txo qhov kub ntawm qhov hluav taws kub, txias cov qauv steel, thiab tus nqi qis. Thaum lub tshuab tsis siv neeg sprinkler tiv thaiv lub ru tsev steel truss load-bearing cov tswv cuab, lub sprinklers yuav tsum tau teem raws li cov kev taw qhia ntawm lub ru tsev load-bearing cov tswv cuab thiab saum toj no steel qauv. Qhov kev ncua deb ntawm cov sprinklers yuav tsum yog li 2.2m. Lub kaw lus tuaj yeem teeb tsa ntawm nws tus kheej lossis ua ke nrog qhov tsis siv neeg tua hluav taws.

Steel qauv fireproof txheej siv

Kev tsim kho ntawm nyias-coated steel qauv nrog fireproof txheej

1. Thaum lub npoo ntawm cov hlau substrate yog xeb-tshem tawm thiab tiv thaiv xeb ua tau raws li qhov yuav tsum tau ua, thiab cov plua plav thiab lwm yam khoom raug tshem tawm, kev tsim kho tuaj yeem nqa tawm.
2. Cov txheej hauv qab feem ntau yog txau. Lub thickness ntawm txhua cov tshuaj tsuag yuav tsum tsis txhob tshaj lub thickness ntawm yav dhau los. Nws yuav tsum tau muab tshuaj tsuag dua tom qab yav dhau los qhuav.
3. Thaum txau, xyuas kom meej tias cov txheej txheem kaw tag nrho thiab cov qauv qhia meej
4. Tus neeg teb xov tooj yuav tsum nqa lub thickness gauge kom pom lub thickness ntawm lub txheej thiab xyuas kom meej tias cov tshuaj tsuag mus txog lub thickness teev nyob rau hauv lub tsim.
5. Thaum tus tsim yuav tsum tau lub txheej txheej kom du thiab du, lub xeem txheej yuav tsum tau troweled los xyuas kom meej tias cov txheej txheej yog txawm thiab du.

Kev tsim kho hluav taws kub retardant txheej rau tuab-coated steel qauv

Cov txheej txheem tuab-txheej hlau cov txheej txheem hluav taws kub yuav tsum tau txau los ntawm lub tshuab nqus tsev twj tso kua mis. Cov cua siab yuav tsum yog 1. Lub cheeb ntawm cov tshuaj tsuag yuav tsum zoo ib yam li cov khoom xyaw.

Kev siv tshuaj tsuag yuav tsum ua kom tiav hauv cov theem. Lub thickness ntawm txhua yam tshuaj tsuag yuav tsum tau ua tom qab ib tug yav dhau los ib txwm qhuav los yog kho. Txoj kev tiv thaiv kev txau yuav tsum tau txiav txim siab raws li kev tsim qauv tsim.

Thaum lub sij hawm tsim kho, tus neeg teb xov tooj yuav tsum siv lub thickness gauge los xyuas lub thickness ntawm txheej thiab tsis txhob txau kom txog thaum nws ua tau raws li cov thickness teev nyob rau hauv tus tsim.

Tom qab cov tshuaj tsuag txheej, mastoids yuav tsum tau muab tshem tawm kom ntseeg tau tias qhov sib npaug
