Description

Novel gold steel pawl formula rag bolt

Technical Field

The utility model relates to the technical field of foundation bolts, in particular to a novel gold steel pawl type foundation bolt.

Background

When the machine member is mounted on a concrete foundation, one end of the bolt having a J-shape or an L-shape is buried in the concrete.

The tensile capacity of the foundation bolt is the tensile capacity of the round steel, and the size is equal to the cross-sectional area multiplied by the allowable stress value, so that the allowable tensile bearing capacity is realized during design.

The anchor bolts are generally made of Q235 steel, namely, are smooth and round. The screw-thread steel Q345 has high strength, and the screw thread for making the nut is not easy to be round. For a smooth round anchor bolt, the burial depth is typically 25 times its diameter, and then a 90 degree hook of about 120mm length is made. If the diameter of the bolt is large and the burial depth is too deep, the square plate can be welded at the end of the bolt, namely, a large head can be made. The embedded depth and the hooks are used for ensuring the friction force between the bolts and the foundation, so that the bolts are not damaged by pulling out. The foundation bolts can be divided into fixed foundation bolts, movable foundation bolts, expansion anchor foundation bolts and bonding foundation bolts. Wherein the method is divided into the following steps according to the different shapes: l-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts and base plate embedded bolts.

The existing foundation bolt still has room for improvement in the ground grabbing force and tensile capacity, and lacks a quick disassembling function, so that the foundation bolt is very laborious and time-delay when being disassembled every time.
