Pe Wall Anchors, Eye Bolt Wall Anchor

Wall Anchors generally refer to Pe expansion screws or Eye Bolt Wall Anchors. Its fixing principle The expansion screw is fixed by using the wedge slope to promote the expansion to generate frictional grip force to achieve the fixing effect. The screw is threaded at one end and tapered at the other end. 

 

Put them together into the hole made in the wall, then lock the nut, the nut pulls the screw out, and the taper is pulled into the iron cylinder, the iron cylinder is expanded, so it is tightly fixed on the wall, generally used for protection Fastening of fences, awnings, air conditioners, etc. on cement, brick and other materials.

 

The Eye Bolt Wall Anchor is composed of a screw and an expansion tube. The tail of the screw is conical, and the diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the conical part moves through the axial movement of the thread.

 

A large positive pressure is formed on the outer peripheral surface of the expansion pipe, and the angle of the cone is small, so that frictional self-locking is formed between the wall, the expansion pipe and the cone, thereby achieving a fixed effect.

First, prepare the applicable alloy drill bit and Eye Bolt Wall Anchor, and make holes on the wall; secondly, drive the expansion screw kit into the hole without removing the nut; connect the keel hanger to the expansion screw again, and use the nut to carry out Fix; Finally, knock the expansion screw and screw into the drilled hole, insert the large hanging piece, and tighten the nut to fix the expansion screw installation. What should I pay attention to?

 

1. When installing the Eye Bolt Wall Anchor, it is necessary to select a suitable alloy drill bit. If the drill bit and the screw are not suitable, it will not be installed smoothly.

 

2. Before installation, it is necessary to remove the debris in the hole, so as not to affect the firmness and stability of the expansion screw installation. If there is debris in the hole, it is easy to grind the thread flat, which will reduce the friction between the thread and the bolt.

 

3. When installing Pe Wall Anchors, choose a hard wall. The harder the wall, the better. Generally speaking, the strength of its installation in concrete is 5 times that of bricks.

 

4. When inserting the expansion screw into the hole, it is necessary to turn the nut outward and the other end inward, and then tighten the nut. At this time, the iron pipe will gradually expand, so that it can play a good role in fixing.

5. When fixing the expansion bolt, don't forget to install the flat washer and the spring washer, install them according to the installation sequence, and finally use the nut to fix it.

 

6. When the nut is also installed, it is necessary to tighten the nut with a tool again. When twisting, do not damage its thread, so as to avoid problems such as loosening and falling of the screw in the future.
