Koj puas tau kuaj xyuas tias qhov hluav taws kub ntsuas hluav taws xob uas koj tau teev tseg thiab teeb tsa muaj cov ntawv ceeb toom qhia tias lawv muaj kev nyab xeeb rau kev siv nyob rau hauv qhov teev I-beam qab nthab?

Engineered wood joists tau tsim txawv dua li cov khoom ntoo joists, thiab vim tias cov khoom siv tsawg dua, lawv hlawv ntawm tus nqi nrawm dua thaum lub tsev hluav taws kub.Vim li no, cov hluav taws kub hluav taws xob siv hauv cov qab nthab yuav tsum tau kuaj xyuas kom lawv ua tau raws li qhov tsawg kawg nkaus. 30-feeb yuav tsum tau.
National Building Council (NHBC), UK tus thawj coj muab kev lav phib xaub thiab kev pov hwm rau kev tsim vaj tsev tshiab hauv tebchaws Askiv, tau hais tias xyoo tas los no yuav tsum tau ua cov kauj ruam kom ntseeg tau tias cov hluav taws kub-resistant downlights ua raws li i-Joists cov tsev siv hauv kev tsim kho tshiab.
Kev ntsuam xyuas tsim nyog lossis kev sim ntawm I-beam-raws li cov qauv hauv pem teb thiab cov qab nthab thiab cov teeb pom kev zoo uas tau teev tseg yog yuav tsum tau ua kom pom tseeb kev teeb tsa.
Koj puas tau kuaj xyuas tias qhov hluav taws kub ntsuas hluav taws xob uas koj tau teev tseg thiab teeb tsa muaj cov ntawv ceeb toom qhia tias lawv muaj kev nyab xeeb rau kev siv nyob rau hauv qhov teev I-beam qab nthab?Tam sim no yog lub sijhawm los xyuas.
Qhov nyuaj ntawm cov kev ntsuam xyuas uas cov hluav taws kub ntsuas hluav taws xob tau nthuav tawm yuav tsum tau nkag siab txhawm rau ua raws li cov cai hais txog lub sijhawm tiv thaiv yam tsawg kawg nkaus.
Ib qho kev sim rau ib lub sijhawm tsis qhia tias cov khoom tsim nyog rau txhua 30/60/90 feeb ntev daim ntawv thov.In thiaj li kom cov khoom ua tau raws li tag nrho 30 / 60 / 90 feeb kev teeb tsa, peb qhov kev xeem sib cais ntawm 30 feeb, 60 feeb thiab 90 feeb yuav tsum tau nqa tawm nrog luminaires ntsia rau hauv lub qab nthab / pem teb kev tsim kho hom thiab cov kev ntsuam xyuas cuam tshuam yuav tsum tau muab pov thawj.
