Quickly-and-fixedly-mounted sleeve, bolt and anchor rod mounting assembly

Abstract

The invention discloses a quickly-and-fixedly-mounted sleeve, bolt and anchor rod mounting assembly. The assembly comprises an anchor rod and a bolt sleeve which are in inserted and threaded connection, wherein the anchor rod comprises a screw section and a convenient-to-install hook section which are integrally connected, the screw section sleeves and penetrates through an expansion mounting sleeve and is in fixed threaded connection with the inner circumference of the bolt sleeve, and meanwhile, the outer periphery of one end of the bolt sleeve is inserted and locked in an expansion port ofthe expansion mounting sleeve; and the screw section, the bolt sleeve and the expansion mounting sleeve are embedded in a building base surface, and the hook section is used for mounting an external load component. Through combination and installation of the anchor rod, the bolt sleeve and the expansion mounting sleeve of special structures, the assembly is simple in structure and quick and convenient to install on the basis of guaranteeing fixed mounting and reliability, and the assembly is especially suitable for the field of small and medium-sized load components.

Description

technical field [0001] The invention belongs to a fastening tool, in particular to a fast fastening and installation of a sleeve bolt and anchor installation assembly. Background technique [0002] As we all know, fasteners are widely used in various construction projects or various facilities and equipment. Commonly used fasteners include different structures such as screws, bolts, and anchor rods. People choose the appropriate fastener structure according to the fastening needs of different application fields. For light and medium load areas, such as various baffles and metal hooks, ropes, lighting rings, hinges, rings or other sealed rings and handles, angle irons, bracket systems, etc., people usually use screw fasteners Or welding to realize the connection, the operation of the overall fastening process is relatively cumbersome; and in terms of long-term use safety, the existing welding fastening or thread fastening has the risk of failure. The applicant also found th...

Problems solved by technology

For light and medium load areas, such as various baffles and metal hooks, ropes, lighting rings, hinges, rings or other sealed rings and handles, angle irons, bracket systems, etc., people usually use screw fasteners Or welding to achieve connection, the operation of the overall fastening process is relatively cumbersome; and in terms of long-term use safety, the existing welding fastening or thread fastening has the risk of failure

The applicant also found that the prior art can also adopt a fastening structure that occupies a large volume, is heavy, and has high fastening costs, which is also not conducive to the convenience of installation. At the same time, the heavy weight of the fastening structure itself will also affect the entire fastening Engineering safety brings new safety hazards
