National Standards For Wrought Iron Guardrails

Txheej txheem cej luam ntawm National Standards for Wrought Iron Railings
Wrought hlau railings yog ib hom kev thaiv uas siv dav hauv cov chaw pej xeem -xws li txoj kev hauv nroog, cov chaw ua si hauv zej zog, thiab cov vaj hauv pej xeem- nrog rau hauv thaj chaw ntiag tug. Lub teb chaws cov qauv rau cov railings feem ntau hais txog cov ntaub ntawv, fabrication, thiab installation kom ntseeg tau tias cov qauv tsim muaj suab, muaj kev nyab xeeb, ruaj khov, zoo nkauj txaus nyiam, thiab siv tau.

Khoom siv Standards
Cov ntaub ntawv rau wrought hlau railings feem ntau muaj xws li steel, cam khwb cia hlau, thiab alloys; cov khoom siv tshwj xeeb yuav tsum raug xaiv raws li qhov xav tau tiag tiag. Cov kev cai hauv tebchaws tau teev tseg tias cov khoom siv hlau yuav tsum ua raws li cov qauv xws li "Quality Carbon Structural Steels for Building Structures" (GB/T 699) thiab "High Strength Low Alloy Structural Steels-Kub-kub{3}}rolled Steel Products and Coils" (GB/T 1591), yuav tsum tau ua raws li cov khoom siv hlau cam khwb cia. Hlau Castings" (GB/T 9439).

Fabrication Standards
Lub fabrication ntawm wrought hlau railings feem ntau muaj xws li kev sib dhos (sib dhos tshuab) los yog vuam txoj kev. Cov kev cai hauv tebchaws xav tau kev tsim khoom kom tau raws li cov qauv kev lag luam; Piv txwv li, kev tsim cov khoom siv steel hlau yuav tsum ua raws li "Txoj Cai Kev Txais Kev Siv Khoom Zoo ntawm Cov Khoom Siv Hlau" (GB/T 50205-2018), thiab kev tsim cov cam khwb cia hlau kav thiab fittings yuav tsum ua raws li "Code for Txais Kev Tsim Kho Zoo ntawm Cov Hlau Hlau Yeeb Nkab thiab Fittings rau Kev Siv Tsev 1207-2018".

Installation Standards
Wrought hlau railings feem ntau yog ntsia rau hauv av los yog cov ntaiv tuav. Lub teb chaws txoj cai tswj kev ruaj ntseg installation raws li cov kev qhia tshwj xeeb; Piv txwv li, kev teeb tsa hauv kev tsim kho yuav tsum ua raws li "Technical Specification for Installation of Steel Structure Components in Building Engineering" (JGJ 81-2002).

Kev txiav txim siab tseem ceeb
Kev sib txuas ntawm cov wrought hlau railing posts thiab cov phab ntsa lossis hauv av yuav tsum muaj kev ruaj ntseg thiab txhim khu kev qha;

Kev tiv thaiv corrosion ntawm wrought hlau railing yuav tsum ua raws li cov qauv tsim los xyuas kom lub neej ntev kev pab cuam;

Qhov siab ntawm wrought hlau railing yuav tsum ua raws li lub teb chaws cov qauv (xws li, qhov siab yuav tsum siab tshaj 1.2 meters), thiab yuav tsum tsis txhob muaj qhov sib txawv ntawm lub railing thiab av;

Kev soj ntsuam ntawm qhov chaw yuav tsum tau ua ua ntej kev teeb tsa; Kev tsim qauv tsim nyog yuav tsum tau muaj nyob rau hauv cov xwm txheej uas muaj qhov nyuaj los yog cov kev cai tshwj xeeb.

[Xaiv]

Wrought hlau railings yog raws li lub teb chaws cov qauv nruj, nrog rau cov kev cai tshwj xeeb npog txhua yam ntawm cov ntaub ntawv thiab fabrication mus rau installation. Kev txhim kho kom raug thiab siv wrought hlau railings pab kom muaj kev nyab xeeb ntawm tib neeg lub neej thiab khoom.
