Izakhiwo eziqoqekile | Ukwethulwa kobuchwepheshe obusha obuthuthukile futhi obuqoqiwe obuqoqiwe

Okuqukethwe kwezobuchwepheshe

Ifreyimu eqoqiwe yensimbi ehlanganisiwe ye-Truss sakhiwo sohlelo ihlanganiswa amakholomu wefreyimu, ama-transver wendiza ama-trusses kanye nama-floor slabs. Amakholomu ahlelwe engxenyeni yendlu ngaphandle kwamakholomu enkampani, ukuphakama kwama-trusses kuyafana nokuphakama kwesakhiwo sendlu, kanye nobude obuphakeme kusekelwa amakholomu aphansi, ama-trusses ahlelwe kumalungiselelo aphansi angenamikhawulo ezansi ezinyaweni eziphakeme nezingaphansi. Ukuphela okukodwa kwesitebhisi phansi kusekelwa emgodini ongaphezulu we-truss, kanti omunye umkhawulo usekelwa emgodini ophansi we-truss engomakhelwane. Kungakha ukuvulwa okukhulu ngokuhlukaniswa kwekholomu kabili, ukuthola ukuvulwa okukhulu nokujula ngokwemisebenzi yezakhiwo kanye nokwenza lula ukuhlelwa kwamahhala. Kungenziwa ngomnyango wesikhashana, setha i-Corridor noma ixhume amakamelo angomakhelwane ngaphandle kwama-webs athambekele phakathi kwezingxenye ngesikhathi sejoist. Njengamanje, cishe yonke imikhiqizo yesakhiwo sensimbi yezakhiwo zamafulethi asungule isakhiwo sohlaka lwensimbi, isakhiwo sensimbi yohlaka, njll., Isebenzisa ukuvumelanisa nesidingo sesakhiwo esiphakeme kakhulu sezakhiwo ezifuywayo.

Ngenxa yezimpawu zokuxhumana kwe-Space Force zesakhiwo se-truss egxilile, i-floor slab ibandakanyeka ekubalweni okuphelele kwesakhiwo ngaphansi kokuhlaziywa kwesiteji, kanye nokuhlanganiswa kwe-floont Izinyathelo nokubuyekezwa kwesibalo kokuxhumeka phakathi kwephansi le-slab kanye neplass Truss Chord kumele kubhekwe ikakhulukazi. Ikakhulu, ukwakheka okuvinjezelwa ukufutheka kwesitalasi kwaphansi kanye nendiza ye-cruss chord kufanele kubhekwe futhi ukubalwa kufanele kubuyekezwe.

Isakhiwo se-Truss esimisiwe ikakhulukazi sifaka ikholomu yensimbi, ama-Plane Trusses kanye nemishayo yohlaka. Esigabeni sokukhiqiza, ngaphandle kokuhlangana nezinga lekhwalithi yesakhiwo sensimbi, izingxenye zensimbi kufanele zigxile ekuqinisekiseni ukunemba kwe-trusses yendiza, ukwamukela izinyathelo zokuqinisekisa nokukhiqiza, nokuthatha izinyathelo zokuqinisekisa ukuthi akukho mbono we-truss ngaphandle kwenqubo yokuhamba ngesikhathi sokuhamba.

Lapho ufaka amakholomu, ama-trusses, ama-beams, ama-brace namanye amalungu amakhulu kwinqubo yokwakhiwa kwe-joist egxilile, kufanelekile ukuwalungisa futhi uzilungiselele kumayunithi ahlukene wokuqina. Enqubweni yokufaka i-floor slab, ukuphakanyiswa okulinganayo kufanele kwamukelwe ukuvikela ukuqina kwama-trusses kwinqubo yokwakhiwa okwenzeka kobuso.

Umdwebo 2 Ukuphakamisa Ukwakhiwa Kwe-Truss

Izinkomba zezobuchwepheshe

1. Inkomba yezobuchwepheshe ekwakhiweni

.

. Ukwakheka kwe-Truss Truss kuzokwakhelwe isimo somkhawulo womthwalo womthwalo kanye nesimo somkhawulo wokusetshenziswa okujwayelekile;

. Ukwakheka kwe-Truss Truss kufanele kubalwe ngomthelela ohlanganisiwe we-beam lapho uhlaziya ukulayisha okuvundlile;

. isilinganiso sokuphakama kokuphakama kwe-truss sizoba ngu-5 ~ 6; Ukuhlukaniswa kwekholomu ende yesakhiwo kube ngu-6 ~ 9m;

. Lapho kusetshenziswa i-hybrid truss, ama-chords kufanele aqhubeke, futhi ukuxhumana phakathi kwe-truss web kanye nama-chords, kanye nokuxhumeka phakathi kwe-truss namakholomu kungaklanywa ngokuya ngokwenza okucaciswayo.

2. Izinkomba zobuchwepheshe ekukhiqizeni nasekukhiqizeni

Ngemuva kokuqanjwa kwamalungu, umnyango wokuhlola kufanele uhlole futhi wamukele imikhiqizo eqediwe ngokuya ngezidingo zokudonswa kwemininingwane nokunikezwa kwale ncazelo. Ukuphambuka kwesimo se-Shape nejometri kufanele kube ngokuya ngezidingo zokwakhiwa nezinhlinzeko ezifanele ze-GB 50205 neJGJ 99 ze-GB 50205 ne-JGJ 99 ze-GB 50205, i-JGJ 99 ye-GB 50205, I-CODE YAMAHHALA YAMAHHALA wekhwalithi yokwakhiwa kwephrojekthi yesakhiwo sensimbi ".

3. Izinkomba zobuchwepheshe ekwakheni nasekufakweni

. Inqubo yokufaka kufanele iqinisekise ukuthi lezo zesakhiwo zakha uhlelo oluzinzile isikhala futhi aluholeli ekuguqukeni okungapheli kwesakhiwo.

.

Izinzuzo Zobuchwepheshe

1. Ukuhlelwa okwenziwe ngesakhiwo se-truss egxilile: Ngenxa yezimpawu ezihlukile zengcindezi zesakhiwo se-truss egxilile, ukucaciswa kwe-truss kungakhiywa ukuze kutholakale ukukhiqizwa okujwayelekile;

2. Ubuchwepheshe bokuhlanganisa obuhlanganisiwe

3. Ukukhiqizwa okuthuthukile kwesakhiwo se-Truss Truss; Amakholomu e-hot rolled H-Type Steel asetshenziselwa amakholomu ensimbi kanye namapayipi ensimbi aqediwe asetshenziselwa imigoqo ye-truss ye-truss, ehlanganiswe nezinto ezizenzakalelayo ze-welding zingabona ukukhiqizwa okuzenzakalelayo kwesakhiwo se-truss enyakazisiwe;

I-4. Ukusebenza okuhle kwezomnotho: Ukusetshenziswa kwensimbi kusindiswa ngo-20% futhi isisekelo kuncishiswa ngama-30%;

I-5. Ukuguqulwa okuhle kwendawo: Isakhiwo se-Span-Span ngaphandle kwamakholomu phakathi singatholakala, okulungele ukuguqulwa kwakamuva kwezokwakha;

6. Ukusebenza kahle kokwakhiwa okuphezulu: ama-node agcotshwe ngokuphelele, ukwakhiwa okulula;

7. Ukuqina okuphezulu kwesakhiwo, induduzo enhle ekusetshenzisweni.

Scope of isicelo

Isakhiwo sakwaJoist esimisiwe silungele izakhiwo eziphakeme eziphakeme ngecebo elijwayelekile lokwakha elifana nefulethi, ihotela, indawo yokuhlala, isibhedlela nokunye ukuqina kokuzamazama komhlaba okungu-6 ~ 8 degree. Isakhiwo esimatasatasa nesakhiwo sohlaka lwensimbi, isakhiwo sensimbi yokusekelwa kwensimbi singahlanganiswa ukuze sihlangabezane nezidingo ezithile zesakhiwo.
