Abstract

The invention discloses a bolt jack-in type attached frame inclined strut and belongs to the field of tower crane attached frame equipment. The bolt jack-in type attached frame inclined strut comprises an inclined strut body composed of an A inclined strut body (4) and a B inclined strut body (8); the inclined strut body is provided with adjusting bolts (7) capable of moving along the inclined strut body and fastening check blocks (6) matched with the adjusting bolts (7) to achieve adjustment of strength of a standard knot; the fastening check blocks (6) are installed between the adjusting bolts (7) and standard knot main chords (9); the two ends of the A inclined strut body (4) are fixed to the attached frame; the B inclined strut body (8) and the A inclined strut body (4) are matched to be fixed; the two ends of the B inclined strut body (8) are also fixed to the attached frame. The adjustable adjusting bolts and the fastening check blocks matched with the adjusting bolts are arranged at the two ends of a brace, so that movable adjustment of the standard knot main chords is achieved, the tightness adjustable and controllable operation is achieved, and compression is convenient and rapid. As the inclined strut is of a two-piece type, and installation is convenient.

Description

technical field [0001] The invention relates to an attachment frame brace, in particular to a bolt-in type attachment frame brace, which belongs to the field of tower crane attachment frame equipment. Background technique [0002] When the tower crane reaches a certain height, its own strength cannot meet the requirements. At this time, it is necessary to add attachment points on the tower body of the tower crane, and fix the tower body with the building wall through connecting rods. The attachment frame is It is the frame surrounding the tower body, which plays the role of connecting the connecting rod and the tower body. [0003] The tower crane fixes the tower body with the building through the attachment frame, which is wrapped around the outside of the four main chords of the standard section. In order to ensure the stability of the standard section, it is necessary to add diagonal braces inside the standard section. At present, most of the oblique braces attached to t...
