Characteristic resistance to tension load.
2. Resistance to steel failure (tension).
3. Resistance to combined pull-out and concrete failure.
4. Resistance to concrete cone failure.
5. Edge distance to prevent splitting under load.
6. Maximum setting torque moment.
7. Minimum edge distance and spacing
Characteristic resistance to shear load (static and quasi-static loading)
8. Resistance to steel failure (shear)
9. Resistance to pry-out failure
10. Resistance to concrete edge failure.
Displacements under short term and long term loading
11 Displacements under short term and long term
Durability
12 Durability of metal parts
Characteristic resistance and displacements for seismic performance categories C1 or C2 (optional)
13 Resistance to steel failure

Eta Approved Wedge Anchor features
ETA-certified screw-type expansion anchors ETA approved through bolt, the overall structure is optimized compared with ordinary screw-type expansion anchors, which improves the anchoring performance, and has significantly enhanced static and dynamic load-bearing performance. ETA screw-type expansion anchors are more The tensile strength of ordinary screw-type expansion anchors is increased by 10%

Long thread: suitable for spacing installation, flexible adjustment
Select the appropriate embedding depth according to the fixed plate thickness. As the embedding depth increases, the tensile force increases. This product has a reliable post-expansion function

TB 7 wedge anchor application

Applicable to the fastening of penetrating objects in non-cracked concrete (such as equipment, channel steel, guide 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，提升了锚固性能，在静态承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，此产品有可靠的后膨胀功能

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、钢结构、扶梯、栏杆、幕墙等）
