Seleksyon materyèl ak ancrage pwosesis nan Spikes wout la
- Ki diferans ki genyen ant Spikes pou dormeur konkrè ak dormeur an bwa?
Dormers konkrè itilize Spikes Threaded (40mnb, rupture pi gran pase oswa egal a 900MPA), ancrage ak ajan souf (rale-soti pi gran pase oswa egal a 60kn) . dormeur an bwa itilize Spikes òdinè (Q235, ry. 40kn) . Spikes Threaded gen fil helical (10mm anplasman, 1 . wotè 5mm) pou bloke mekanik; Spikes òdinè gen rasin lis ak tèt djondjon (30mm dyamèt) yo anpeche rale-soti.
- Ki sa ki "pwen konstriksyon ivè yo" pou ancrage souf?
Nan sezon fredi (<5℃), sulfur anchoring requires: ① preheat sleeper holes to 30-40℃ (hot air gun); ② mix sulfur:cement:sand:paraffin=1:0.8:1.3:0.04, heat to 180-200℃ (slight smoke); ③ insulate with quilts for 2h after anchoring. A northeast project without preheating had average pull-out of 45kN, requiring full rework and ¥300,000 loss.
- Ki sa ki se "avantaj la vit geri" nan Spikes résine-ancrage?
Anchors résine (E . G ., metakrilat) geri mwens pase oswa egal a 5 minit, rive 60kn rale-soti fòs nan 1 èdtan nan 20 degre, ideyal pou reparasyon ijans {{7} lè; (Mete résine jete lank (Φ28mm, 150mm long); ③ Thorne Spike anba a epi tann pou geri . Yon reparasyon efondreman tren lè l sèvi avèk lankr résine retabli trafik nan 30 minit, ekonomize 4 èdtan vs souf ancrage .
- Ki sa ki se baz la pou chwazi "penti anti-korozyon" pou Spikes?
Zòn Kòt yo itilize penti zenk-aliminyòm (85% Zn, 15% al), pase 1, 000- tès sèl espre sèl . mòn imid itilize epoksidik poud penti ({{6} Yon tren bò lanmè Fujian ranplase 40% Spikes galvanised wouye ak penti zenk-aliminyòm, ekonomize 60% nan depans antretyen malgre 20% pi wo depans .
- Ki jan Spike "asyèt" afekte tras la?
Spike asyèt yo ta dwe mwens pase oswa egal a 1 degre (ang soti nan Travelers pèpandikilè) . depase sa ki lakòz: ① tren lateral deplasman pi gran pase oswa egal a 2mm; ② 15% rediksyon fòs rale-soti; ③ Enstalasyon Fastener difisil . Yon sit konstriksyon ki gen 3 degre asistan echwe enspeksyon kalib tras, transfere ¥ 180, 000 nan re-ancrage depans . itilize Spike pozisyon (presizyon ± 0 . 5 degre) oswa mekanik Peewses.
