Embodiment Construction
[0016] refer to figure 1 , The present invention is made of rod body 1, wedge body 2, supporting plate 3, flange collar 4. The rod body 1 is a rod body that has been cold-rolled and rolled into an open tubular shape. There is a slit along the entire length of the tubular rod body, and its cross section is circular. One end of the rod body 1 is covered with a supporting plate 3 and a flange collar 4 The other end is barbed. Several wedges 2 are housed in the rod body 1, and a certain distance is left between the wedges.

The present invention relates to a full-length multipoint wedge-expanded pipe slot anchor bolt, belonging to the field of engineering support, and is formed from bolt body, wedge body, support and flange shrink-ring. Said bolt body is made into the pipe form, along the full-length of pipe bolt a slot is opened, in the interior of said bolt body several wedge bodies are held, one end of the bolt body is covered with support and is equipped with flange shrink-ring, and the anchorage end of the anchor bolt is equipped with a beard.
Description
Technical field [0001] The invention belongs to the support field of mines, geotechnical engineering, underground engineering, side slope engineering and tunnel engineering. Background technique [0002] Anchor type There is a problem cement anchor Since the cement rolls should be soaked in water before use, if the soaking time is too long, the When the cement roll is installed, the anchor hole will be blocked, so that the anchor cannot be installed, and the cement roll will If the soaking time is too short, it will cause raw materials in the middle of the cement roll, which will make the cement roll up. Not much use. Ordinary seam Anchor The installation is laborious, the rod body is easy to corrode, and the anchoring force is difficult to be reliably guaranteed. The tensile strength does not match the anchoring force. Due to the material problem of the rod body, sometimes the anchor The phenomenon that th...
