Galvanized Commercial Steel Structural Pipe Truss Roof YeShopping Mall

Pipe truss inoreva chivakwa chelattice chinoumbwa nekubatanidza matanda akatenderera kumagumo.Iyo truss inoita iyo truss chimiro chehupfumi, uye chimiro chakareruka muhuremu, uye zviri nyore kugadzira maumbirwo akasiyana siyana kuti aenderane nezvinangwa zvakasiyana, senge zvinongotsigirwa trusses, arches, mafuremu, uye shongwe.

Kuenzaniswa neiyo grid chimiro, iyo tubular truss chimiro inochengetedza yakaderera chord longitudinal nhengo uye spherical majoini egidhi furemu, ayo anogona kusangana nezvinodiwa zveakasiyana mafomu ekuvaka, kunyanya kuvakwa kweakatenderedza arch uye anopokana akakomberedzwa maumbirwo anobatsira kupfuura grid chimiro.Kugadzikana kwayo kumativi ose kwakafanana, kuchengetedza kushandiswa kwezvinhu.Iyo simbi yepombi truss chimiro inogadzirwa pahwaro hwegridhi chimiro.Kana ichienzaniswa neyegridhi chimiro, ine yakasarudzika mabhenefiti uye practicability, uye huwandu hwesimbi yekugadzira zvakare hunowedzera hupfumi.

Kuita:

1. Simba:

Iyo indekisi yesimba resimbi inoumbwa ne elastic muganho σe, goho muganho σy, uye tensile muganho σu.Iyo yakagadzirwa inobva pakusimba kwegoho resimbi.Kusimba kwegoho repamusoro kunogona kuderedza huremu hwechimiro, kuchengetedza simbi, uye kuderedza mutengo.Iyo tensile simba σu ndiyo yakanyanya kushushikana iyo simbi inogona kumira pamberi pekutadza.Panguva ino, chimiro chinorasikirwa nekushanda kwayo nekuda kwepurasitiki yakakura deformation, asi chimiro hachina kukanganisa uye hachiputsi, chinosangana nezvinodiwa zvechimiro chekudzivisa kudengenyeka kusingawanzoitiki.'Σu / σy kukosha kunogona kutariswa separamita yesimbi simba rekuchengetedza.

2. Plasticity:

Iyo plasticity yesimbi inowanzo reva chivakwa chekuve neakakosha epurasitiki deformation pasina kutyora mushure mekushushikana kwapfuura iyo goho poindi.Iwo main indexes kuyera epurasitiki deformation kugona kwesimbi kurebesa δ uye chikamu shrinkage ψ.

3. Kutonhora kwekukotama kuita:

Iko kutonhora kwekukotama kuita kwesimbi chiyero chekuramba kwesimbi kutsemuka kana deformation yepurasitiki ikaitika pakamuri yekupisa.Iyo inotonhora yekukotama kuita kwesimbi ndeye kushandisa inotonhora yekukotama kuyedza kuyedza kubhenda deformation kuita kwesimbi pasi pedhigirii rekukotama rakatsanangurwa.

4. Kuoma kwesimba:

Iko kusimba kwesimbi kunoreva kugona kwesimbi kutora mechanical kinetic simba panguva yekutyoka pasi pemutoro wekukanganisa.Icho chinhu chemuchina chinoyera kupikisa kwesimbi kuti ibate mutoro.Inogona kukonzera brittle kutyoka nekuda kwekudzikira tembiricha uye kushushikana mupfungwa.Iyo kukanganisa kuoma indekisi yesimbi inowanzo kuwanikwa kuburikidza nemhedzisiro bvunzo yeyakajairwa bvunzo zvidimbu.

5. Welding performance:

Welding performance yesimbi inoreva welding majoini nekuita kwakanaka pasi pemamwe welding process mamiriro.Welding performance inogona kukamurwa kuita welding performance uye welding performance mune welding process.Welding performance in the welding process inoreva kubatwa kweiyo welding seam uye simbi padhuze newelding seam kuti irege kutsemuka inopisa kana kutonhora kutsemuka kwakatsemuka panguva yewelding process.Kuita zvakanaka welding kunoreva kuti pasi pemamwe welding process mamiriro, iyo weld simbi uye iri pedyo base simbi haizotsemuka.Kushanda kwewelding maererano nekugona basa kunoreva kusimba kwekuita uye ductility yenzvimbo yakakanganiswa nekupisa pane weld seam.China inotora iyo welding performance test nzira muwelding process, uye zvakare inotora iyo welding performance test nzira muchimiro cheusability.

6. Kugara kwenguva refu:

Pane zvinhu zvakawanda zvinokanganisa kusimba kwesimbi.Yekutanga ndiyo yakashata corrosion resistance yesimbi, uye matanho ekudzivirira anofanirwa kutorwa kudzivirira kuparara kwesimbi uye ngura.Matanho ekudzivirira anosanganisira: kugara uchigadzirisa pendi dzesimbi, kushandiswa kwesimbi yakakoshwa, uye kushandiswa kwematanho akakosha ekudzivirira pamberi pehupombi hwakasimba hunoodza senge acid, alkali, uye munyu.Iyo zinc ingot inogadziriswa pajasi, uye mvura yegungwa electrolyte ichangoerekana yaparadza zinc ingot kutanga, kuitira kuti iwane basa rekudzivirira jekete resimbi.Chechipiri, nekuda kwekushisa kwepamusoro uye mutoro wenguva refu, simba rekuparadza resimbi rakaderera pane iro resimba renguva pfupi.Nokudaro, iyo yakareba-yepamusoro-yepamusoro simbi inofanira kuongororwa kuti iwane simba renguva refu.Iyo simbi inozongove yakaoma uye brittle nekufamba kwenguva, inova chiitiko che "kuchembera".Iko kukanganisa kuoma kwesimbi pasi petembiricha yakaderera inoyedzwa.

Kuenzaniswa neyechinyakare simbi trusses ine yakavhurika muchinjiko-zvikamu (H-yakaita simbi uye I-yakaita simbi), zvinhu zvepombi truss dhizaini zvakanyanya kugovaniswa kutenderedza kwazvakarerekera axis, kuitira kuti muchinjikwa-chikamu ive yakanaka compressive uye flexural- torsional kutakura kugona uye kuoma kukuru.Pasina gusset ndiro, chimiro chiri nyore.Chinhu chinonyanya kukosha ndechekuti tubular truss chimiro chakanaka muchitarisiko, chakanakira kuenzanisira uye chine imwe yekushongedza maitiro.Kushanda kwese kwepombi truss chimiro chakanaka, torsional rigidity yakakura, uye chitarisiko chakanaka.Zviri nyore kugadzira, kuisa, kushandura, uye kusimudza;iyo simbi pombi padenga truss yakagadzirwa nesimbi inotonhora-yakaumbwa yakatetepa-yakavezwa simbi ine mwenje chimiro, yakanaka kuomarara, simbi inochengetedza, uye inogona kupa yakazara kutamba kune Zvakanakira zvesimba rezvinhu, nezvimwewo, zvine hupfumi, kunyanya mune strut uye rutsigiro system. inodzorwa nereshiyo yakatetepa.Zvivako zvine chimiro ichi zvivakwa zveveruzhinji.Chimiro chine hunhu hwekutaridzika kwakanaka (inogona kuvakwa kuita flat shape, round arch shape, anopokana curve shape), kugadzirwa kuri nyore uye kuisirwa, kugadzikana kwakanaka kwechimiro, kusimba kwedenga repamusoro, uye kunaka kwehupfumi.

Zvigadzirwa zvesimbi zvekambani yedu zvinogona kusangana nemhando dzakasiyana dzepasi rose senge Australian standard, New Zealand standard, British standard uye American standard.Gamuchira kubvunza kwako.
