PC is a komponent ishlatilgan qurilish, transport, suv konservatsiyasi, va boshqa maydonlar, shuningdek ma'lum sifatida 22precast beton komponentlar". Misol uchun, oldindan tayyorlangan temir beton ustun poydevor , oldindan tayyorlangan temir tuzilishi temir po'lat ustun poydevor, ko'cha chiroq billboard ustun mustahkamlangan beton poydevor, oldindan tayyorlangan qavat plita, va boshqalar. Mos ravishda, an'anaviy kast-in-place beton talab talab saytda talab qilinadi saytda qoliplash, on-sayt quyish% 2c va on-sayt texnik. Precast beton komponentlari keng ishlatiladi yilda qurilish, . transport, suv tejash, va boshqa maydonlar, va play a muhim rol yilda mamlakat's iqtisodiy rivojlanish.
2. Afzalliklari pc komponentlari:
PC komponentlari ning afzalliklari mavjud energiya tejash, atrof-muhit muhofazasi, xarajatlar kamayishi, va ta'minlash foydali funktsiyalar, va foydalanish funktsiyalari. Hozirgi vaqtda, construction units around the world have application methods for PC components, and mainland China is still in the development and research stage. In recent years, with the rise of many new building concepts such building industrialization, energy conservation and emission reduksiya, sifatli va xavfsizlik, va ekologik atrof-muhit muhofazasi, as as a katta raqami of infrastructure construction in in the process of urbanization.
Progress: PC komponentlari katta yaxshilanishi the assembl and construction progress.
In terms of cost: Compared with traditional in-situ molding, the molds produced in the factory can be recycled and reused, and the overall cost is relatively low; mechanized manufacturing requires less manpower, and with the increase of labor, the large-scale production of PC components Production will be more cost-effective.
Atrof-muhit muhofazasi: Keyin PC komponentlari ishlatiladi ichida qurilish maydoni, the ish yuki the construction site is sezilarli darajada kamaytirilgan, va chang ifloslanishi va shovqin ifloslanishi sezilarli kamayadi.
3. Classification of PC components% 3a
Pate% 3a
Qavat PC komponentlari asosan ichiga kichik-span kompozit plitalar, kichik-span steel grid frames, va katta-span kompozit plitalar % 3b the asosiy komponentlari of cast-in-place beton ichiga katta-span cast-in-place plitalar va katta-span cast-in-place slabs kiradi.
Chiroq% 3a
The PC component forms of the beams are small-span composite beams and large-span composite beams; the main components of cast-in-place concrete are cast-in-place trabeculae and large-span cast-in-place beams.
Ustun% 3a
PC a'zosi of the column is in forma of non-formwork and needs to be poured stina.
Devor% 3a
PC komponentlari devor o'z ichiga oladi oldindan tayyorlangan devorlar, ikki qatlamli laminatlangan kesish devorlar, va cast-in-place devorlar.
At present, the method of on-site molding, on-site pouring, and on-site maintenance is adopted for construction, so that the assembly-type construction has higher time flexibility, is convenient for construction, and can greatly save construction time.
