Hlau txhua: hom, daim ntawv thov, thiab ntaus ntawv mounting bases nyob rau hauv lawv

Nyob rau hauv niaj hnub siv yog feem ntau siv hlau txhua uas pab raws li ib tug them nyiaj yug rau sab nrauv thiab sab hauv qhov chaw ntawm lub tsev. Yog tsis muaj lawv tsis ua hauj lwm, vim hais tias lawv tsim ib tug txhawb ncej. Steel lug yog siv ntau ntau, vim hais tias lawv yog yus muaj los ntawm siab durability thiab yooj yim ntawm installation. Ib txhia designers siv rau lawv raws li hniav ntsiab ntawm cov vaj tse los yog ib tug neeg cov chav.

Lub constituent ntsiab

Tag nrho cov hlau kem muaj ob peb qhov chaw: ntxeev ntawm lub pas nrig thiab puag. Headroom - sab qaum kev ib ntawm uas bears lub load ntawm lub ru tsev thiab kev hloov tsheb mus rau lub pas. Nyob rau hauv nws muab xam yuav siv sij hawm mus rau hauv tus account tsis tau tsuas yog tus luj so beams, trusses, tab sis tshwj xeeb tshaj yog lawv cov mounting.

Nyob rau hauv nruab nrab ib feem ntawm lub kem yog ib tug pas nrig uas hau lub load rau hauv av (puag). Yog hais tias nws yog ib qho tseem ceeb yuav tau xav txog lub xam ravnoustoychivost them nyiaj yug, uas yog coj yuav tsum tau saj zawg zog nrog hwm rau saum ntoo khaublig seem ntawm lub axes. Qhov no txoj ntsiab cai yuav ua rau nws tau txuag rau cov ntaub ntawv thiab kom tau ib tug ruaj khov kev teeb tsa. Haib khoom yuav siv tam ribs.

Base - ib lub hauv paus qauv uas hau lub load rau lub hauv paus. nws tseem yog tsim nyog rau mounting them nyiaj yug. Thaum xam cov thickness ntawm lub hauv paus yog muab rau tus account thiab cov kev siv cheeb tsam feem, thiab lub hauv paus khoom.

hom

Material ua therefrom ntau yam intricate nrhiav tiam sis muaj ntau hlau txhua muaj ib tug ntoo khaub lig seem nyob rau hauv daim ntawv ntawm ib tug I-beam, ib lub los yog ib lub raj. sectional qhov ntev yog payment rau lub dag lub zog muab xam (feem ntau yog contraction) thiab stability. Qhov no kawg cov yam ntxwv yog nyob rau hauv lub xub ntiag ntawm kev sib txuas racks fachwerk li al.

Nyob rau hauv lub constructive tshuaj, sab tej zaum yuav mus li, tshaj, thiab tus qhab seem. Tus tsim ntawm qhov ntoo khaub lig-section yog ib tug hluas pas nrig, uas yog siv nyob rau hauv frameless vaj tse, Hangars thiab warehouses. Nws yog ua tau rau nruab cov khoom nrog ib tug tshaj plaws lifting peev xwm ntawm 20 tons.

Tshaj kem tsim rau installation peev xwm los ntawm ntau tshaj 20 m. Vim nws tshwj xeeb ntoo khaub lig-section tsub kom lub rigidity rau dabtsi yog khoov thiab paub stability. Qhov no tsim muaj ob cov kabmob ceg: yooj yim thiab crane.

Composite hlau txhua yog tsis tshua muaj siv, thiab tej zaum yuav siv sij hawm sib txawv loads (hais txog cov kev axis). Lawv yuav tsum mus rau:
- installation ntawm cranes thaum uas tsis muaj qhov chaw siab tshaj;
- mounted cranes nyob rau hauv tiers;
- reconstruction ntawm vaj tse.

kheej ntawm daim ntawv thov

Lub steel txhua yog nyob rau hauv zoo kawg thov vim cov uas tsis muaj nqi, yooj yim ntawm installation, yooj yim uas pub ntxiv tshaj, loj me me. Ib tug loj tus naj npawb ntawm zoo tso cai rau kom siv lawv rau qhov kev siv ntawm:
- muaj vaj tse (e.g., khw);
- civil vaj tse (multi-storey vaj tse rau txawv hom phiaj);
- saib ntsoov txog npog thiab choj.
- vaj tse uas yuav tsum tau tshwj xeeb ua (lub peev xwm ua tau ntau yam ntawm architectural thiab tsim ntaub ntawv).

yam ntxwv tsom xam

Ua ntej koj yuav nqa tawm lub installation ntawm hlau lug, nws yog tsim nyog los ua kom tiav lawv daim ntawv qhia txog kev them nyiaj. Rau qhov kev siv ntawm steel ncej feem ntau siv monolithic tshaj puag tsis muaj tsom iav. Los mus laij lub tsim yuav tsum tau sau cov ntaub ntawv ntawm tag nrho cov loads, raws li zoo raws li los mus txiav txim tus naj npawb, loj, me, txhua, qhov cuab lub zog thiab qhov tob ntawm pw. Nyob rau hauv cov ntaub ntawv no, nws tag nrho cov nyob rau hauv lub ceeb thawj ntawm lub tsev thiab nta hauv av (denser dua nws yog, qhov tsawg resistant nws yog yuav tsum tau).

Lub xam yuav tsum tau nqa tawm thiaj li hais tias cov load yog faib tusyees rau qhov chaw nyob rau hauv lub hauv av. Yog hais tias cov teeb meem mob, nws yog ua tau los npaj ib tug muaj zog puag (xuab zeb los yog gravel). Thaum paub coj tus kheej muaj peev xwm ntawm hauv paus thiab lub tsev luj, yog yooj yim xam tag nrho puag thaj tsam ntawm lub tib tug. Ib tug load yog ces payment rau txhua them nyiaj yug.

Fundam nyob rau hauv hlau kem txawv ntawm cov pa bases nyob rau hauv uas txhua lub caij yog cais los ntawm lwm tus. Lawv yog cov sib tsis yog kev cob cog rua, yog li tus tsim uas tsis yuav tshwm sim nyob rau hauv ib tug misalignment ntawm lub tsev.

installation ntawm cov me nyuam yaus

Cov ntaub ntawv bases tsis muaj tsom iav thiab nruab nrog thauj tog rau nkoj bolts tuav cov khoom los luj. Lawv qhov siab yog xws li hais tias hauv qab ncej neeg thiab lub hnub twb kaw pem teb anchors. Yog hais tias lub installation ntawm lub kab yuav nkag mus ntawm lub hauv paus tsawg kawg yog 4 meters, nws yog tej zaum yuav siv prefabricated qhob podkolonniki. Cov qis kawg ntawm xws li ib tug kev tsim kho yog tsau nyob rau hauv lub khob, thiab lub Upper ntug yog txawm peem rau nrog anchors.

Rau ib sab racks xav tau ib tug ntau lub hauv paus, txawm yog hais tias muaj yuav tsum tau nyob rau hauv lub hlau thiab ua kev reinforced lug. Taw tes rau tus ncej neeg kom tseeb installation ntawm lub anchors thiab kev tso kawm yog cov neeg ntawm kev hloov - Substrate npaj.

installation ntawm txhua

Installation ntawm hlau lug yuav tsum tau nqa tawm thiaj li hais tias cov sib txawv ntawm cov axes tau tsis pub SNIP (tshwj xeeb tshaj yog cov ntaub ntawv ntawm as chaw). Tej yam yooj yim txhua teem raws li ib tug tag nrho, thiab qhov hnyav yuav ntawm lub constituent ntsiab. Yuav kom mount, lawv yuav tsum txeeb, tsa, coj mus rau txoj kev txhawb zog, dlhos thiab ruaj ntseg. Gripping lug yog siv slings, uas yog muab tso rau hauv lub ncoo (e.g., ntoo). Lifting yog ua los ntawm rotating los yog zawv zawg.

Muaj ob peb txoj kev txhawb nqa cov puag rau puag (nws yog xim hlau txhua ntshav yuav pom hauv qab no):
- rau nws saum npoo tsis muaj grout tshuaj
- rau steel daim hlau uas gravy tshuaj;
- beams, ntsia (yuav tsum tau Grouting puag).

Nyob rau hauv kev xyaum, siv lub yooj yim txoj kev ntawm installation. Nyob rau hauv cov ntaub ntawv no, cov khau yog mounted rau ib tug steel welded ntawm lub thaub qab thiab sib raug zoo mus rau hauv qab ntawm lub kab. Thaum tus tsim yuav tsum tau qhia thiab tsau, lawv poured ib tug tov.

Mounting ntawm txhua muaj xws li ib tug meej kawm tuab si lug nrog kev pab los ntawm num seev thiab pitches. Nyob rau tib lub sij hawm lawv mus soj ntsuam lawv tus cim, Verticality thiab txoj hauj lwm nyob rau hauv lub hom phiaj. Rau mounting lug siv thauj tog rau nkoj bolts: yuav tsum tau 2-4 daim. rau txhua txog li 15 m. Yog xav paub ntxiv stability muab kev zawm hniav, uas raug muab tshem tawm tom qab qhov kawg kho. Dua ntsiab ntxiv dag zog struts, ties thiab ib ntus kev zawm hniav. Yog xav tau ib tug ruaj khov moj khaum yog zoo dua mus rau Mount tus pej thuam ua ke nrog rau cov crane girders.
