Momwe Mungasankhire Bolt Yoyenera ya Nangula ya Structural Integrity

Zofunikira za Anchor Bolt.

Maboti a Nangula amasamutsa katundu kuchokera panyumba kupita ku maziko ake a konkriti, kukana kutulutsa, kukameta ubweya, ndi kugwedera. Mosiyana ndi mabawuti wamba, amapangidwa kuti azilumikizana ndi konkriti kudzera m'makina, kukangana, kapena zomatira.

.Mapulogalamu Oyamba:

1. Kugwirizana kwazitsulo zachitsulo
2. Kuyika makina olemera
3. Bridge ndi column baseplates
4. Mipanda ya nyumba ndi mizati yopepuka

Mitundu ya Anchor Bolt ndi Zochita Zochita

.

.1. Cast-in-Place Anchors.

• .Kuyika: Ophatikizidwa panthawi yothira konkriti.
• .Mphamvu: Kulemera kwambiri (mpaka 50 kN mphamvu yamakokedwe).
• .Zabwino Kwambiri: Malumikizidwe ofunikira pama milatho kapena okwera kwambiri.

.2 . Nangula Zowonjezera (mwachitsanzo, Nangula za Wedge)..

• .Mechanism: Imakula motsutsana ndi makoma obowo ikamangika.
• .Load Capacity: 20-35 kN mu konkire yolimba.
• .ZolepheretsaPewani m'malo ong'ambika kapena opanda dzenje.

.3 . Sleeve Anchors.

• .Kusinthasintha: Yoyenera konkriti, njerwa, ndi chipika.
• .Ntchito Yapakatikati: Zoyenera pamanja, magawo a HVAC (10–25 kN).

.4 . Kudzera pa Bolts.

• .Kupanga: kudutsa gawo lonse lapansi; amafuna nut/washer msonkhano.
• .Gwiritsani Ntchito Case: Malumikizidwe achitsulo-to-konkriti omwe amafunikira kusokoneza pafupipafupi.

.5 . Adhesive Anchors.

• .Kugwirizana: Epoxy kapena utomoni wamankhwala umadzaza mabowo obowoledwa.
• .Ubwino: Palibe mphamvu yakukulitsa, yabwino mtunda wautali

5-Masitepe Kusankha Njira.

1.Tanthauzirani Zofunikira za Katundu.

• Katundu wosasunthika (mwachitsanzo, zikwangwani): Nangula wa Giredi 4.8–5.8.
• Zolemetsa zamphamvu / zivomezi: Giredi 8.8+ yokhala ndi epoxy kapena njira zowonjezera.

2.Unikani Makhalidwe a Substrate.

• Konkire yolimba: Nangula wokulitsa kapena wedge.
• Chotsekera / njerwa: Nangula zomatira kapena manja.

3.Dziwani Zofunikira Zolimbana ndi Corrosion.

• M'nyumba/zouma: Zokutidwa ndi Zinc (ISO 4042).
• Kuwonekera m'mphepete mwa nyanja / mankhwala: Chitsulo chosapanga dzimbiri A4 (ISO 3506).

4.Werengerani Malire a M'mphepete ndi Malo.

• Mtunda wocheperako wam'mphepete = 5x nangula m'mimba mwake.
• Kutalikirana pakati pa anangula ≥10x m'mimba mwake.

5.Tsimikizirani Kuthekera kwa Kuyika.

• Kuyika-pamalo: Pamafunika kukonzekera mwadongosolo.
• Kuyika pambuyo: Pamafunika zida zobowola ndi nthawi yochiritsa (mitundu yomatira).

Zolakwika Zofala ndi Kuchepetsa.

.Cholakwika 1: Kugwiritsa ntchito anangula a wedge mu konkire yong'ambika.
.Solution: Sinthani ku nangula zomatira kapena ma helical bolts.

.Cholakwika 2: Kulimbitsa kwambiri anangula okulitsa.
.Zotsatira: Kupaka konkriti; torque mpaka 75% ya malire opanga.

.Cholakwika 3: Kunyalanyaza kuwonjezeka kwa kutentha.
.Konzani: Siyani kusiyana kwa 2-3mm mu anangula a manja kuti musinthe kutentha.

Malangizo Omaliza.

1. Pazinthu zokhala ndi katundu wambiri, yang'anani patsogolo ma anchor kapena epoxy.
2. M'malo owononga, tchulani chitsulo chosapanga dzimbiri A4 chokhala ndi zokutira zochepera 2mm.
3. Tsimikizirani zisankho za nangula kudzera pakuyesa kutulutsa (kutsata kwa ICC-ES AC193).
