Ndezvipi Zvishandiso Zvinodiwa PaChivakwa Chepamusoro-soro cheSimbi?

simbi-chimiro-detail-4 (1)

Simbi zvivakwa kuvakashandisa simbi sechinhu chekutanga chinotakura zvinhu (sematanda, makoramu, uye trusses), inowedzerwa nezvinhu zvisingatakuri zvakadai sekongiri nemadziro. Mabhenefiti eSimbi, akadai sesimba rakanyanya, huremu, uye kudzokorodza, akazviita tekinoroji yakakosha mukuvakwa kwemazuva ano, kunyanya kune yakakura-span, yakakwirira-kukwira, uye zvivakwa zvemaindasitiri. Zvivako zvesimbi zvinoshandiswa zvakanyanya munhandare, horo dzekuratidzira, skyscrapers, mafekitori, mabhiriji, uye zvimwe zvinoshandiswa.

Main Structural Forms

Chimiro chechimiro chechivakwa chesimbi chinoda kusarudzwa maererano nebasa rekuvaka (senge span, kureba, uye mutoro). Mhando dzakajairika ndedzinotevera:

Chimiro Form Core Principle Applicable Scenarios Typical Case
Frame Structure Inoumbwa nematanda nemakoramu akabatana kuburikidza neakaomesesa kana akasungirirwa majoini kuti agadzire mafuremu akarongwa, anotakura mitoro yakatwasuka uye yakachinjika mitoro (mhepo, kudengenyeka kwenyika). Multi-storey / yakakwirira-kukwira mahofisi ehofisi, mahotera, makamuri (kazhinji ane urefu ≤ 100m). China World Trade Center Tower 3B (chidimbu chefuremu)
Truss Structure Inosanganisira nhengo dzakatwasuka (semuenzaniso, simbi yemakona, simbi yakatenderedzwa) inoumbwa kuita mativi matatu. Inoshandisa kugadzikana kwemakona matatu kuendesa mitoro, kuve nechokwadi chekugovera kwesimba rakafanana. Zvivakwa zvakakura-zvakare (span: 20-100m): gymnasiums, horo dzekuratidzira, fekitori workshops. Denga reNational Stadium (Bird's Nest)
Space Truss/Lattice Shell Structure Yakagadzirwa nenhengo dzakawanda dzakarongwa nenzira yenguva dzose (semuenzaniso, makona matatu akaenzana, masikweya) kuita grid yenzvimbo. Mauto anogoverwa munzvimbo, achigonesa nzvimbo huru dzekuvharira. Zvivakwa zvekuwedzera-zvikuru-zvakakura (span: 50-200m): nhandare dzendege, nzvimbo dzemagungano. Denga reGuangzhou Baiyun Airport Terminal 2
Portal Rigid Frame Structure Inoumbwa nembiru dzakaoma furemu uye matanda kuita "gedhi"-yakaita furemu. Makolamu mabhesi anowanzo kusungirirwa, akakodzera kutakura mitoro yakareruka. Single-storey maindasitiri zvidyarwa, matura, Logistics nzvimbo (span: 10-30m). Musangano wekugadzira wefekitari yemotokari
Cable-Membrane Structure Inoshandisa tambo dzesimbi dzakasimba (semuenzaniso, tambo dzesimbi) semutoro unotakura zvinhu, wakafukidzwa nezvinhu zvinochinjika membrane (semuenzaniso, PTFE membrane), ine zvese zviri zviviri transmittance uye yakakura-span kugona. Zvivakwa zvepasi, mhepo-inotsigirwa membrane gymnasiums, toll station canopies. Swimming Hall yeShanghai Oriental Sports Center

Main Materials

Simbi yakashandiswa mukatisimbi yekugadzira zvivakwainofanirwa kusarudzwa zvichibva pane zvimiro zvemutoro zvinodiwa, yekuisa mamiriro, uye mutengo-kushanda. Iyo inonyanya kuiswa muzvikamu zvitatu: mahwendefa, profiles, uye mapaipi. Specific subcategories uye maitiro ndeaya anotevera:

I. Plates:
1. Mahwendefa esimbi akakora
2. Medium-thin steel plates
3. Mahwendefa esimbi ane muenzaniso

II. Nhoroondo:
(I) Hot-yakakungurutswa profiles: Inokodzera ekutanga-inotakura zvinhu zvinotakura, inopa yakakwirira simba uye kuoma.
1. I-matanda (kusanganisira H-matanda)
2. Channel simbi (C-matanda)
3. Engle simbi (L-matanda)
4. Flat simbi
(II) Cold-formed thin-walled profiles: Yakakodzera kureruka uye yakavharirwa zvikamu, inopa yakaderera deadweight
1. C-matanda inotonhora
2. Kutonhora-kuumbwa Z-matanda
3. Cold-formed square uye rectangular pombi

III. Mapaipi:
1. Mapombi esimbi asina musono
2. Welded simbi mapaipi
3. Spiral welded pombi
4. Special-shaped simbi mapaipi

Steel Structure Advantageous

High Strength, Light Weight: Simbi yekusimba uye inomanikidza masimba akakwira zvakanyanya kupfuura kongiri (inenge 5-10 nguva yekongiri). Tichifunga zvakafanana zvinotakura zvinodikanwa, simbi yezvimiro zvesimbi inogona kuve diki muchinjika-chikamu uye yakareruka pahuremu (inenge 1/3-1/5 iyo yekongiri zvimiro).

Kuvaka Nekukurumidza uye Kukwirisa Maindasitiri: Steel structurezvikamu (zvakadai seH-matanda nemabhokisi ebhokisi) zvinogona kuenzaniswa uye kugadzirwa mumafekitari ane millimeter-level chaiyo. Vanongoda kubolting kana welding yekusangana pa-saiti, kubvisa kudiwa kwenguva yekurapa senge kongiri.

Yakanakisa Seismic Performance: Simbi inoratidza yakanakisa ductility (kureva, inogona kukanganisa zvakanyanya pasi pemutoro pasina kutyora kamwe kamwe). Munguva yekudengenyeka kwenyika, zvivakwa zvesimbi zvinotora simba kuburikidza nekugadzirisa kwavo, kuderedza njodzi yekuparara kwechivako.

High Space Utilization: Zvikamu zviduku zvakayambuka zvezvikamu zvesimbi (zvakadai sesimbi tubular columns uye nhete-flange H-matanda) inoderedza nzvimbo inogarwa nemadziro kana makoramu.

Yakanaka Nezvakatipoteredza uye Yakanyanya Kushandiswa Kugadzirwazve: Simbi ine imwe yemhando yepamusoro yekudzokorodza zvakare pakati pezvivakwa zvekuvaka (kupfuura 90%). Zvivako zvesimbi zvakaputswa zvinogona kudzokororwa uye kushandiswa zvakare, kuderedza marara ekuvaka.
