Abstract

The invention discloses a stainless steel combined type foundation bolt. The stainless steel combined type foundation bolt is characterized in that the stainless steel combined type foundation bolt comprises a first screw rod, a second screw rod and a connector, the connector is provided with a screw hole matched with the first screw rod and the second screw rod, built-in threads are arranged on the wall of the screw hole, one end of the first screw rod is connected to one end of the connector, and one end of the second screw rod is connected to the other end of the connector; and the first screw rod and the second screw rod are made of different materials. According to the stainless steel combined type foundation bolt, part of the bolt is made of stainless steel, and part of the bolt is made of carbon steel, so that the production cost is saved; and the connector is arranged, so that moisture permeation is effectively prevented, and corrosion of the bolt is prevented.

Description

technical field [0001] The invention relates to a stainless steel combined anchor bolt, which belongs to the technical field of bolts. Background technique [0002] If the current anchor bolts or bolts buried deep in the ground are made of carbon steel, they are cheap but easy to rust, and if they are all made of stainless steel, the cost is too high. [0003] Anchor bolts are tools buried in the ground or foundation to connect the earth or ground foundation with machinery and equipment. Generally, smooth and round Q235 carbon steel is used, while Q345 rebar is strong, but it is not as easy to make a nut thread as a smooth round. For light round anchor bolts, The burial depth is generally 25 times its diameter, and it has a 90-degree hook about 120mm long. If the bolt has a large diameter (eg 45mm) and the burial depth is too deep, a square plate is usually welded at the end of the bolt. [0004] China Invention Patent No. 201720425974.3, the patent name is "A Type of Pla...
