Chii chinonzi 7-character tsoka? 

Iwe unonzwa 7-mavara anotsika achikandwa-kandwa mufastener specs kana ekare einjiniya manotsi, uye kutaura chokwadi, maziso evanhu vazhinji anopenya. Zvinonzwika seimwe arcane kodhi. Mumutsara wangu webasa - kubata nekubatanidza zvimiro, mabhaudhi eanchor, uye anorema base mahwendefa - haisi kodhi, asi yakananga, ingangoita yekare-yechikoro nzira yekutsanangura bhaudhi. kudzika kudzika. Kuvhiringidzika kunowanzotanga nekuti vanhu vanofungidzira kuti ndeye bhaudhi remuviri rine mavara manomwe akadhindwa pairi. Hazvisizvo. Mutauro unotsanangurwa, pfupiso. Chaizvoizvo, inoreva kureba kunodiwa kwebhaudhi rinofanirwa kuvigwa mukongiri kuti rikurudzire simba rayo rakazara, uye 7-character chikamu chimiro chekuburitsa iyo dimension uye dzimwe nguva humwe hunhu mune yakasimba, yakamisikidzwa tambo yemavara nenhamba. Ndakaona izvi zvichiuya zvakanyanya mumadhirowa enhaka kana pakubata nemamwe maindasitiri emidziyo yekumisikidza kubva mukupera kwezana ramakore rechi20.

Anatomy ye7-Character String

Ngatitaurei kuti mavara manomwe aya anomiririrei. Haisi yepasirese, asi yakajairika pateni yandakasangana nayo chinhu chakaita se 'L45x300'. Ndiwo mavara matanhatu, unogona kutaura. Wedzera chivakashure kana chivakashure chemhando yeshinda kana kupedza, worova nomwe. Iyo 'L' inogona kureva imwe bhaudhi mhando (seJ-bolt kana L-bolt yekumisikidza). Iyo '45' inogona kuva dhayamita mumamirimita, uye '300' iyo kudzika kudzika. Imwe fomati inogona kunge iri 'M36-400', uko 'M' iri metric shinda, '36' dhayamita, uye '400' ndiyo inomisikidzwa. Kiyi kudzika-iyo 300mm kana 400mm-ndiyo yakakosha nhanho yekutsika. Icho chikamu chinovimbisa kuti bhoti haingobudi kunze pasi pemutoro. Ini ndinorangarira purojekiti yekudzoreredza iyo yekutanga 1980s specs yakadana 7-mavara tsoka yekutsika mabhaudhi, spec: H-B 5/8×24. Zvakatitorera zuva kuti tinzwisise kuti H-B ingangove yakatevedzana yemugadziri, 5/8 dhayamita, uye 24 inches yekumisikidza. Iwo 7-character ndiye ainyanya kutsanangudza kune iyo kirasi yezvirevo.

Nei iyi fomati? Pre-digital drafting. Yakanga iri nzira yakabatana yekurongedza ruzivo rwakakosha munzvimbo shoma pane chirongwa chekudhirowa. Hauna kukwanisa kunyora ndima. Waida tambo yekuti mugadziri ane ruzivo kana saiti foromani aigona kutarisa onzwisisa. Dambudziko nhasi nderekuti zivo iri kupera. Vadiki mainjiniya vanozviona uye vanofanirwa kuenda kunochera kuburikidza neakasakara manyoro. Ndanga ndiri murume iyeye pafoni ndichitsanangurira kune akavhiringidzika kontrakta kakawanda kupfuura zvandinogona kuverenga.

Zvazvinoreva ndezvese nezvekutakura mutoro. Iyo yakareba yakamisikidzwa inoverengerwa zvichienderana nekongiri yekumanikidza uye simba regoho rebhoti kuti ive nechokwadi chisungo chakakodzera. Yakanyanya kupfupika, uye unoisa panjodzi yekutadza kuburitsa kunze. Ini ndinogara ndichiyambuka-references aya echinyakare specs ane anchor dhizaini makodhi, seACI 318 Appendix D kana zvakaenzana nayo, kuratidza kukwana. Dzimwe nguva fungidziro dzekare dzaive dzakanyanya kuchengetedza; dzimwe nguva, neshungu, vakanga vari muganhu.

Real-World Application uye Common Pitfalls

Unozvionera kupi chaizvo izvi? Zvivakwa zvekare zvekugadzira magetsi, zvigadziko zvepombi zvemichina mikuru yemaindasitiri, uye zvimiro zvekutsigira zvinorema zvinotakura. Chimiro chesaiti kazhinji ndicho chipingamupinyi chikuru. Iwe unowana kudhirowa kunodaidza a 7-maitiro anotevera bhaudhi rine 400mm embedment. Iwe unoratidza kumusoro, uye iripo kongiri hwaro ingori 500mm gobvu. Iwe haugone kunyudza 400mm pasina kufuridza pasi. Zvino chii? Mugadziri wepakutanga anogona kunge akafungidzira hombe kongiri block. Apa ndipo panosangana mugwagwa. Iwe unofanirwa kugadziridza patsva block block (inodhura, inopedza nguva) kana kutsvaga imwe anchoring sisitimu, senge post-yakaisirwa adhesive anchors kana undercut anchors, iyo inogona kuwana hukuru hwakafanana nekumisikidzwa kupfupi. Asi izvo zvinoda kudzokororwa kwemaitiro akazara.

Imwe gomba ndeyekudzivirira ngura. Mazhinji eaya ekare specs aive akajeka kabhoni simbi mabhoti. Muchirimwa chemakemikari kana nzvimbo yekuchenesa mvura, bhaudhi iro, rakavigwa mukongiri, rinogona kupera kubva mukati. Ndanga ndiri pakuferefeta kweforensic uko kukundikana kwanga kusiri nekuda kwekureba kwekumisikidzwa asi nekuda kwekurasikirwa kwechikamu kubva mukuora pane kongiri interface. Zvino, pandinoona 7-character spec, imwe yemibvunzo yangu yekutanga ndeye nharaunda. Inofanira kuva isina tsvina here? Panofanira kuva nejasi rekudzivirira here? Iyo yekutanga spec inowanzo nyarara pane izvi.

Sourcing ndiwo musoro wayo. Iwe haugone kungopinda mune yakajairwa fastener shop uye wokumbira 7-mavara anotsika bolt. Unoda kuturikira chirevo ichi kuchiisa kumatemu echimanjemanje, anotengeka: giredhi rezvinhu (semuenzaniso, ASTM A307, A193 B7), dhayamita, shinda yeshinda, uye kureba kwese (kudzika kwekuiswa pamwe nekureba kwakafumurwa). Apa ndipo panova nemugadziri akavimbika igoridhe. Kambani yakadai Handan Zitai Fastener Kugadzira Co, Ltd., yakavakirwa muChina's main fastener production hub muYongnian, Hebei, kazhinji inokwanisa kugadzira zvinhu izvi zvisiri-standard, zvinorema-basa kuti zvinyatsotsanangurwa. Nzvimbo yavo iri padyo nehombe dzekufambisa dzinoshanda kune logistics, asi kukosha chaiko kuri murutsigiro rwavo rweinjiniya kududzira izvi zvinodiwa zvenhaka kuita chigadzirwa chinogadzirwa.

Case in Point: A Retrofit Gone Awry

Ini ndichagovera nyaya pfupi yakanga isiri njodzi asi yekupotsa-inoda nguva nemari. Takanga tichiisa compressor itsva pane padhi iripo mune yekare yekunatsa. Iyo mifananidzo, kopi yekopi, yakatsanangurwa Anchor Bolts (7-char tsoka): 4 req'd, ona tsanangudzo 5/B. Detail 5/B yakadzima asi yakaratidza chimwe chinhu senge D32-550. Takazvidudzira se 32mm dhayamita, 550mm embedment. Faundesheni yacho yakanga yakakora zvakakwana, saka takatenga mabhaudhi—kuburikidza nomutengesi womunzvimbomo uyo akatipa kondirakiti yekugadzira. Mabhoti akasvika, takaaisa mu template, akadurura grout. Munguva yekupedzisira torque-up, rimwe remabhaudhi rakatanga kutenderera. Yakanga yadhonza. Takamisa zvese.

Mushure mekunyatsoongorora, takaona kukanganisa kwedu. Muchinyorwa chepakutanga chengano, iyo D haina kumira padhayamita; yaimiririra yevaridzi deformed-bar anchor type kubva kumugadziri weGerman akaparara. Iyo 32 yaive dhayamita, asi iyo 550 yaive kureba kwese, kwete kudzika kwakadzika. Iyo embedment yakanyatso cherechedzwa kumwe kunhu se400mm. Bhoti yedu yaive neiyo isiriyo deformation patani padivi pe shank ye550mm yakazara, zvichireva kuti simba rebhondi raive rakadzikira pane zvaidiwa. Taifanira kubvisa grout, kubvisa mabhaudhi, uye kutanga patsva. Chidzidzo chacho? Iyo 7-character spec yaive nzira, asi isu hatina kuchera zvakadzika muzvinyorwa zvinotsigira zvemazuva ano. Isu takafunga kuti iyo fomati yaive yepasirese. Zvakanga zvisiri.

Ichi ndicho chikonzero ini zvino ndichibata chero fungidziro yakadaro senzvimbo yekutanga yebasa rehutikitivha. Zvinoda kuongororwa kweiyo yakazara nhoroondo yeprojekiti zviyero, zvinhu zvakatemwa kubva panguva iyoyo, uye dzimwe nguva kunyange kusvika kune vakasiya mainjiniya kana purojekiti yakakosha zvakakwana.

Mazuvano Kuenzana uye Kusashanda

Saka, ipfungwa yekuti a 7-maitiro anotevera isingachashandi? Zvikuru, hongu, maererano neshoko chairo. Yemazuva ano engineering software uye BIM (Kuvaka Ruzivo rweModhesi) modhi yakanyudzwa (hapana pun yakarongedzerwa) yese iyi data parametrically. Bolt yeanchor muRevit modhi ine akawanda ezvivakwa zvakanamirwa pairi: dhayamita, kureba, kuisirwa, zvinhu, simba rekupedzisira, corrosion kuramba, yekuisa torque. Kudiwa kwetambo yemavara manomwe yakavanzika hakuna.

Zvisinei, nheyo yacho haisati yapera zvachose. Kutsanangura kudzika kwakajeka, kusinganzwisisike kudzika kunonyanya kukosha kupfuura nakare kose. Tinongozviita zvakasiyana. Chimiro chemazuva ano chinogona kuverenga: Anchor Bolt: ASTM F1554 Giredhi 105, 1-1/4 dhayamita, hex musoro, ine 36 kushoma kuisirwa mukongiri, f'c = 4000 psi. Ndiwo mamwe mavara, asi ari pachena. Nhaka ye7-character system chiyeuchidzo kuti ive chaiyo uye yakazara. Izvo zvakamanikidza chirango chekupfupika icho isu pamwe takarasikirwa, asi isu tawana kujeka.

Kune vanogadzira uye vatengesi nhasi, shanduro ndiyo yakakosha. Pandinogamuchira mufananidzo wekare, ndinogadzira pepa rakachekwa rakajeka rinobvisa jargon. Ndinogona kunyora: Pachinhu chakanyorwa 'L45x300' pakudhirowa A-101, ipa 4x mabhaudhi anchor, zvinhu: 304 Stainless Simbi, dhayamita: 45mm, yakazara shinda kureba kuve 700mm ne300mm yeshank yakachena yekumisikidzwa, shinda kune ISO metric coarse pitch. Ini ndozotumira izvo kumugadziri akaita saZitai Fastener kuti atore. Kujeka kunodzivirira kukanganisa kunodhura. Chikwata chavo, chinoziva zvese zvekare uye zvitsva zviyero, chinowanzo shanda kubva ipapo pasina nyaya.

Mhedziso: Zviri Nezve Kudzika, Kwete Iyo Jargon

Pakupera kwezuva, 7-character tsoka chikamu chenhoroondo yehunyanzvi jargon. Kana iwe uchirangarira chinhu chimwe, ngachive ichi: musimboti wetemu unonongedza kune zvakakosha zvakanyanya kudzika kudzika yechinhu chinosunga mukongiri. Icho chifananidzo chenguva yekukurukurirana kweinjiniya. Nhasi, tine maturusi ari nani uye akajeka mwero, asi dambudziko rakakosha rinoramba rakafanana: kuve nechokwadi chekuti chinhu chesimbi chakasungirirwa mukongiri kutakura mutoro. Iyo temu inopera, kuverenga kunowedzera kuoma, asi kudiwa kwekuomesera kutarisisa kune zvakadzama pamusoro pechitoro chekudhirowa uye panzvimbo yebasa hachichinji. Usave wakasungirirwa pakugadzirisa mavara manomwe; tarisisa pakuona nzira yekuremerwa yavakaitirwa kuve nechokwadi. Ndiko kutorwa chaiko kubva kumakumi maviri emakore ekuona zvinhu izvi musango, kubva kumifananidzo yakareruka kusvika kune yakasvibiswa negirisi sketches.
