Kengaytirilgan metall, sinovdan o'tgan va haqiqiy material bo'lib, ajoyib ko'p qirrali xususiyatga ega va turli xil ilovalarda foydali bo'ladi. Uning moslashuvchanligi o'rab olish, himoya qilish, ishlab chiqarish jarayonlari, qurilish loyihalari, strukturaviy yordam va hatto estetik bezaklarga ham tegishli. Ushbu material turli kontekstlarda o'zining jasoratini namoyish etadi va ko'pincha karbonli po'latdan, alyuminiydan va zanglamaydigan po'latdan tayyorlanadi. Plitalar ko'rinishida taqdim etilganda, uning o'ziga xos xususiyatlari - mustahkamlik, qat'iylik va ajralmas fazilatlar - o'zaro uyg'unlik bilan o'zaro ta'sir qiladi va ochiq to'r tuzilishini ta'minlaydi. Ushbu mesh arxitekturasi yorug'lik, tovush, issiqlik, havo va suyuqliklarning to'siqsiz uzatilishini osonlashtirish qobiliyati bilan ajralib turadi.
Hech qanday shubha yo'qki, kengaytirilgan metall ko'p yillar davomida mavjud bo'lgan materialdir. Bu juda ko'p qirrali material bo'lib, uni har qanday narsa uchun qo'shimchalardan himoya qilishgacha, qurilishga va bezakgacha ishlatish mumkin.
Karbonli po'lat, alyuminiy va zanglamaydigan po'lat to'rni tayyorlash uchun eng ko'p ishlatiladigan materiallardir. U choyshab sifatida qurilganida, kuchli, qattiq, yirtilib ketmaydigan ochiq to'r yorug'lik, tovush, issiqlik, havo va suyuqliklarning o'tishiga imkon beradi, lekin istalmagan narsalarning (yoki odamlarning) bo'shliqqa kirishiga yo'l qo'ymaydi. Kengaytirilgan metall panjaraning har bir varag'i bitta mustahkam po'latdan yasalganligi sababli, panjarada bo'g'inlar yoki choklar yo'q.
Kengaytirilgan metall ikkita asosiy variantda mavjud: Standard Expanded Metal (SXM) and Flattened Expanded Metal (FXM).
In SXM, the bonds and strands are at an angle to the original plane of the solid sheet after it has been die cut and expanded. The term “raised” often refers to SXM as a finished product after it has been die cut and expanded.
FXM materiali silliq, tekis sirt qoldirib, sovuq haddelenmiş. Bu SXM materialidan taxminan 5 foizga engilroq.
Choosing a grating must be based on the design’s general characteristics, such as safety, open space, and ease of maintenance. After selecting the basic product, you will need to select the right style of grating for the job in order to satisfy the load-and-span requirements. Here are some tips for selecting the right style:
- Determine the clear span
- Determine the load condition and the amount of load
- Select the appropriate grating style
When placing an order for expanded metal, it’s essential to keep key considerations in mind. To start, the sheet size is denoted by SWD (Short Way of Diamond) followed by LWD (Long Way of Diamond), like this: SWD x LWD.
For catwalk applications, the LWD will typically run along the short edge of the expanded metal grating. For example, 30 pieces, 3.0# carbon steel expanded metal grating catwalks, 10 feet SWD by 3 feet LWD, providing greater support over the walkway’s span.
Plitalar o'lchami va kesish turi, shuningdek, agar maxsus varaq o'lchamlari kerak bo'lsa, o'lchovli o'lchamlarga tolerantlik ko'rsatilishi kerak. Odatda, kengaytirilgan metall panjara belgilangan o'lchamdagi (SWD va LWD) birinchi bog'lanishda kesilgan bog'lanishdir. Biroq, agar kerak bo'lsa, u tasodifiy ravishda yaqinroq bardoshlik uchun kesilishi mumkin.
Buyurtma berishda siz xohlagan metall turini belgilang. Masalan, karbonli po'lat, zanglamaydigan po'lat, alyuminiy va boshqalar.
Kengaytirilgan metallga buyurtma berishda har doim quyidagi ma'lumotlar kiritilishi kerak:
- Specify the number of pieces wanted
- SWD olmosning nominal o'lchamini belgilang (masalan, 3/4 dyuym)
- Varaq uslubini belgilang (masalan, #18; yoki alyuminiy bo'lsa, 0,081)
- Specify whether standard or flattened
- Kerakli material turini belgilang (masalan, karbonli po'lat, zanglamaydigan po'lat va boshqalar).
- Kerakli varaq hajmini belgilang (masalan, 4 fut SWD va 8 fut LWD)
Bundan tashqari, kengaytirilgan metall haqida gap ketganda, eng muhim atamalarni takomillashtirish muhimdir.
Nomidan ko'rinib turibdiki, kengaygan metall bo'lagi olmosning uzun o'lchamiga parallel ravishda kesilganda yon qirqish sodir bo'ladi.
Odatda, tasodifiy yon qirqish varaqning LWD o'lchamiga parallel ravishda amalga oshiriladi, shuning uchun siz varaq yuzasida ochiq olmoslarga ega bo'lasiz. SWD o'lchamining standart bardoshliligi varaqning har ikki tomoni bir vaqtning o'zida kesilganda +/- 1/16 dyuymni tashkil qiladi.
Bog'lanish tomonini kesish - bu bog'lanishning o'rta chizig'ida belgilangan kenglikdagi bog'lanish uzunligi bo'ylab qilingan kesma. Kamber oddiy yoki yassilangan metallni bir-biriga bog'lashni qiyinlashtirganligi sababli, yon tomonlarini kesishga harakat qilish odatda amaliy emas.
Tasodifiy kesish kengaygan metall qismini aniq uzunlikka (LWD) kesish natijasida yuzaga keladi. Bu jarayon odatda ikkala uchida ochiq olmos qoldiradi, lekin ikkala uchi bir vaqtning o'zida kesilganda yaqin bardoshlik (+/- 1/16 dyuym) paydo bo'ladi.
A diamond is end sheared by cutting a piece of expanded metal parallel to the diamond’s short way by means of a knife.
Oxirgi bog'lanishni kesish amalga oshirilganda, kengaytirilgan metallning bir qismi belgilangan uzunlikka (LWD) kesiladi. Ikkala uchiga +/- 1/16 dyuymli bardoshlik qo'llaniladi. Bir uchi SWD ga parallel ravishda bog'langan holda kesiladi, boshqa uchi odatda ochiq olmos naqshiga ega. (Izoh: Ikki uchi qirqib olinganda +/- 1/2 olmos tolerantligi bilan belgilangan uzunlik bo'ylab uchini kesish amalga oshiriladi.)
To'rtburchaklik varaqning barcha to'rt chetini kesishni anglatadi, maksimal bardoshlik har bir oyoq uchun 1/16 dyuym.
In addition, bond shearing produces closed diamonds that are easier to handle and safer to handle, but it often results in higher costs and requires greater dimensional tolerances. In most cases, random shearing is less expensive, except where scrap (“drop off”) is excessive, is more difficult to handle, and poses a greater safety risk due to the sharp edges remaining on the diamond.
Ko'rib turganingizdek, kengaytirilgan metall dunyosi tekislikdan uzoqdir. Litsenziyalangan arxitektor va/yoki pudratchi har doim sizning aniq ishingiz uchun maslahat beradigan eng yaxshi odamdir. Bu ko'p o'lchovli bo'lib, to'g'ri turni va kesishni tanlashda ko'plab omillarni hisobga olish kerak.
