Siv cov kev faib ntawm tsev mus ib lub sij hawm ntev, lub slightest inaccuracy nyob rau hauv lub installation ntawm pob zeb lintels, tshwj xeeb tshaj yog central, tsev fuabtais, yuav ua rau misalignment thiab yam ntxwv tsis ua hauj lwm. Tab sis thaum lub zoo kawg li lub tsev twb ua tau lub tsev, nws twb kwv yees lub neej rau centuries.

Nrog lub advent ntawm cib raws li ib tug lub tsev cov ntaub ntawv uas thaum xub thawj jumper tseem twb arched. Tab sis nws yog yooj yim mus ua hauj lwm, txij li thaum lub cib ntawm tib yam loj, thiab nrog ib tug jumper ntaus ntawv yuav ua lub nqaws ntawm qhov ntau thiab thickness, thiab yog li tiav rau yam voos kheej-kheej ntawm aperture

Tam qhob choj squared

Thaum cov neeg ua vaj tse ntawm ntoo lintel tshaj qhov rai los yog qhov rooj yog ib tug tuab cav, ib tug overlay qhov rais nrog ib tug loj npoo.

Nrog rau txoj kev loj hlob ntawm science, technology, lub foundations ntawm cov tshiab technologies nyob rau hauv kev tsim kho, nyob rau hauv particular nrog cov kev taw qhia ntawm kev reinforced, ua kev reinforced nyob jumper squared. Cov webs muaj ib lub ntoo khaub lig seem, lub dav ntawm tsis muaj ntau tshaj li 250 hli. Lawv yog npaj rau kaw qhib nyob rau hauv cib ntsa ntawm thaj thiab pej xeem vaj tse. Cov khoom uas manufactured los ntawm ib tug series ntawm 1.038.1- 1.

Lub yees duab saum toj no qhia tau hais tias lub squared choj. Nyob rau hauv tas li ntawd mus rau lub squared, ua slab, beam, pem hauv ntej jumper thiab sau. Tag nrho cov ntawm lawv yuav mus rau qhov hluav taws kub-resistant lug.

Piv txwv li, BOP choj 19-3 2-n.

• 2 qhia tus xov tooj ntawm tus ntoo khaub lig-sectional cheeb tsam;
• PB yog ib lub npe - squared jumper;
• 19 - Length nyob rau hauv dm;
• 3 - lub tsim load nyob rau hauv KN / m (kgf / m);
• n txhais tau tias muaj mounting tabs.

Tus thawj tug lej nyob rau hauv lub npav, los ntawm 1 mus rau 5, hais txog qhov luaj li cas ntawm ib tug ntoo khaub lig-seem ntawm cov khoom.

Cov jumpers blockboard, nyob rau hauv lub npe ntawm uas tus thawj daim duab 1, nrog transverse ntev 120h65 (siab) hli, tej zaum yuav sib tshooj lub keeb nyob rau hauv qhov uas tsis yog-ntxwv wythe 120 hli.

Yog hais tias tus thawj lej yog tsim nyog 2, tus ntoo khaub lig-sectional qhov ntev yog 120x140 (h) hli. Cov jumpers mas loads txog li 400 kg / m thiab yog siv nyob rau hauv nws tus kheej-txhawb phab ntsa.
Yog hais tias tus thawj lej yog tsim nyog 3, tus ntoo khaub lig-sectional qhov ntev yog 120h220 (siab) hli. Cov jumpers yog muaj zog dua, lawv muaj peev xwm withstand load los ntawm cov slab.

Txhua jumper muaj ib tug meej kabmob ntawm qhov tob ntawm lub phab ntsa, nyob ntawm seb nws load-tau cov kabmob muaj peev xwm. Yog hais tias lub load rau ntawm tus choj yog tsis ntau tshaj 400 kgf / m, tus kabmob tob tej zaum yuav 120 hli, Yog hais tias ib tug load siab tshaj 400 kg / m, tus kabmob tob muaj yuav los ntawm 170 hli rau 230 hli.

Nyob rau hauv thiaj li yuav kom khaws cov jumper, koj yuav tsum paub lub dav ntawm lub hau qhib, lub thickness ntawm cov phab ntsa uas qhib thiab seb nws yog raws li tshooj.

Nyob rau ntawm phab ntsa thickness saum toj no cov lus qhib stacked ob los yog peb jumpers blockboard, nyob rau Stacked tam los ntawm cov overlapping.

Tshwj xeeb tshaj yog tsheb thauj mus los thiab stacking

Tej zaum, tshwj xeeb tshaj yog nyob rau hauv lub thauj, koj yuav tsum xam qhov ntim squared jumpers. Thaum cov lus teb yuav tsum coj mus rau hauv tus account uas lub consignment yuav tsum muaj ib pawg qhov siab ntawm tsis muaj ntau tshaj li 2 m, txhua jumper yuav tsum tau muab tso rau hauv ob ntoo taub txuas.
Squared jumpers ntsia saum qhib tom qab tag masonry mus rau lub sab saum toj ntawm cov lus qhib, uas yuav them tshwj xeeb mloog mus rau cov horizontality ntawm lawv txoj hauj lwm. Upper dav hlau jumper yuav tsum yaug nrog rau sab saum toj ntawm lub brickwork.

Jumpers muaj teev nyob rau hauv lub txheej ntawm MAAs-zeb M100 tshuaj.
Lub jumper yog nyob rau ntawm cov sab nrauv lub ntsej muag ntawm cov phab ntsa, yog teem rau 65 hli hauv qab no rau lwm, txoj kev ua ib tug peb lub hlis twg ntawm qhov yuav tsum tau thaum txhim kho qhov rais, thiaj li tsis mus cua blew lawv.
