EspañaThe end of the tube that the car repair anchor extends into the tube sheet hole is rolled to cause the inner wall of the tube to expand continuously, causing plastic deformation, increasing the tube diameter, and the tube head is completely attached to the tube sheet hole wall, and forcing the tube sheet to produce elastic deformation . When the expander is removed, the elastic deformation of the tube sheet is about to return to its original shape, and the plastic deformation of the tube end cannot be restored. As a result, the tube sheet is tightly hugged by the tube end, so as to achieve the purpose of sealing and tightly connecting the two.
In addition, the car repair anchor must choose the appropriate embedding depth according to the thickness of the fixed roof. With the increase of the embedment depth, the pulling force will increase according to the increase of the embedding depth. After being reliable, the car repair anchor also has an expanding effect. And in order to ensure the quality of the expanded tube, tools, measuring tools, and operators must be done before the tube expands. During inspection, the protective coating on the wall of the pipe hole should be cleaned first, and the processing quality of the pipe hole wall should be checked. There should be no sand holes, dents, edge burrs and longitudinal nicks; the depth of the longitudinal or spiral nicks should not be greater than 0.5mm and the width It shall not be greater than 1mm, and the distance from the notch to the edge of the hole shall not be less than 1/3 of the thickness of the hole wall, and shall not be less than 4mm.
The advantages of car repair anchor are mainly concentrated in the following aspects:
1. In addition to the standard anchoring depth for installation, each anchor size can also be applied to shallow buried depth, which provides greater flexibility during installation. This is Fawer car repair anchor.
2. The thread of the master is suitable for spacing installation and can be flexibly adjusted. This is Fawer car repair anchor.
3. The cold process makes the material good ductility, even if the drilling is not perpendicular to the concrete indication, installation and adjustment can be carried out to a certain extent. This is Fawer car repair anchor.
4. Prevent thread damage when the anchor bolt is knocked into the hole, and the embossing on the head can clearly show the depth of embedment.
At present, the car repair anchors sold in the No. 1 Fastener Mall are mainly made of 304 and 316 materials, with specifications ranging from M6*50 to M16*120. They are all well-known brand Xin Guozhong, and they have stocks in stock. Welcome to pay attention to the public No. 1
