The invention discloses a replaceable anchor bolt assembly for concrete foundations, comprising a steel skeleton, an anchor barrel, an anchor rod, a bushing, a sealing ring and a nut assembly; the steel skeleton is fixedly connected with the anchor barrel and can be pre-embedded in concrete In the foundation, the anchor rod and the anchor cylinder are fixedly connected by threads, and the bushing and the sealing ring are arranged between the anchor rod and the anchor cylinder. The structure of the fixed connection between the anchor tube and the steel skeleton can not only ensure the positioning accuracy of the anchor rod, but also ensure the anchoring performance of the anchor rod in the foundation; the anchor tube and the anchor rod are connected by threads, which not only realizes the replaceability of the anchor rod, It also enhances the tightness of the combination of the anchor tube and the anchor rod; by setting a bushing and a sealing ring between the anchor rod and the anchor tube, the tightness of the anchor bolt during installation is guaranteed. Each part of the replaceable anchor bolt assembly is organically combined to form a good stress-bearing whole with the concrete foundation, thereby realizing the integrity and replaceability of the anchor bolt assembly.
Description
Technical field [0001] The present invention belongs to the technical field installation, anchor structure relates to a concrete foundation, particularly to a concrete base anchor for the replaceable assembly. Background technique [0002] In the installation apparatus, the anchor bolt and the base is a common method of coupling a general structure fixed installation. Coupled to the base using anchor bolts in the fixed structure and various types of equipment, structures and devices for high demands on the settlement, it will usually be adjusted periodically according to a result of the elevation apparatus foundation settlement observation, in order to meet the requirements . When adjusting the elevation of the device, is sometimes necessary to repeatedly disassemble nut fixture, because of the nut fixing apparatus is repeatedly disassembled and the like or corrosion reasons, there may be cases of the threaded bolt local failure or damage can occur which when the anchor bolts nee...
