Wedge thauj tog rau nkoj xa tawm mus rau EU yuav tsum ua tau raws li cov cai ntawm ETA ntawv pov thawj.Cov kev ntsuam xyuas tseem ceeb suav nrog:

Basic Works Requirement
1. Mechanical resistance thiab stability
Cov yam ntxwv tsis kam rau tension load.
2. Kev tiv thaiv rau steel tsis ua hauj lwm (nruj).
3. Kev tiv thaiv kev sib koom ua ke rub tawm thiab kev ua tsis tiav.
4. Kev ua haujlwm tsis zoo ntawm lub khob hliav qab.
5. Ntug nrug los tiv thaiv kev sib cais hauv qab thauj khoom.
6. Qhov siab tshaj plaws lub sijhawm torque.
7. Yam tsawg kawg ntawm ntug thiab qhov sib nrug
Yam ntxwv tsis kam rau shear load (static thiab quasi-static loading)
8. Resistance rau steel tsis ua hauj lwm (shear)
9. Resistance rau pry-tawm tsis ua hauj lwm
10. Resistance rau pob zeb ntug tsis ua hauj lwm.
Kev xaav nyob rau hauv lub sij hawm luv luv thiab lub sij hawm ntev loading 
11 Kev tshem tawm hauv lub sijhawm luv thiab ntev
Durability
12 Durability ntawm hlau qhov chaw
Cov yam ntxwv tsis kam thiab hloov chaw rau seismic kev ua tau zoo pawg C1 lossis C2 (yeem)
13 Resistance rau steel tsis ua hauj lwm

Eta Pom Zoo Wedge Anchornta
ETA-certified ntsia hlau hom expansion anchorsETA pom zoo los ntawm bolt, tag nrho cov qauv yog optimized piv nrog zoo tib yam ntsia hlau-hom expansion thauj tog rau nkoj, uas txhim kho lub anchoring kev ua tau zoo, thiab muaj zog zoo li qub thiab dynamic load-bearing kev ua tau zoo.ETA ntsia hlau hom expansion thauj tog rau nkoj yog ntau dua Lub zog tensile ntawm zoo tib yam ntsia hlau hom expansion thauj tog rau nkoj yog nce 10%

Ntev xov: haum rau qhov sib nrug ntawm kev teeb tsa, hloov kho tau yooj yim
 Xaiv qhov tsim nyog embedding qhov tob raws li cov phaj tuab ruaj khov.Raws li qhov embedding qhov tob nce, lub zog tensile nce.Cov khoom no muaj kev txhim khu kev qha tom qab nthuav dav

TB 7 wedge anchordaim ntawv thov

Muaj feem xyuam rau txoj hlua khi ntawm cov khoom nkag mus rau hauv cov pob zeb uas tsis muaj qhov tawg (xws li cov khoom siv, channel steel, kev taw qhia rails, brackets, steel structures, escalators, railings, curtain walls, etc.)

特点

ETA认证的螺杆式膨胀锚栓，整体结构相较于普通螺杆式膨胀锚栓进行了优化了途化。载和动态承载性能都有明显的增强,ETA螺杆式膨胀锚栓比普通螺杆式膨胀锚栓抗拉强度提高了10%

长螺纹：适用于间距式安装、可灵活调节

依固定板厚选择合适的埋入深度，随着埋入深度的增加，拉力增加，此产哟有彯靠的萎

应用

适用于非开裂混凝土中贯穿式物件的紧固（如设备、槽钢、导轨、支架、钢绶幝、扠牢绶幝、
