Description

Technical Field

[0001] The utility model belongs to the field of building electromechanical installation engineering, and in particular relates to an adjustable bolt assembly structure applied to a support and hanger. Background Art

[0002] During the construction of engineering pipelines, it is usually necessary to lay various integrated pipelines. For some pipelines that need to be laid overhead, it is necessary to use pipeline supports and hangers for hoisting and fixing. For the connection of the supports and hangers, connectors are needed to fasten and assemble between the columns and crossarms. At present, connectors are generally used in conjunction with bolt fasteners to connect and fix between the columns and crossarms. When fixing, the bolt fasteners are fixed by penetrating the mounting holes on the connectors and the column crossarms. For example, Chinese patent document: CN202122731938.9 discloses an adjustable anti-torque connection structure for assembled pipeline supports and hangers, including vertical channel steel, transverse channel steel and connectors. Multiple mounting holes are symmetrically opened on the side walls of the vertical channel steel and the transverse channel steel. The mounting holes are square. Connectors are symmetrically arranged at the connection between the vertical channel steel and the transverse channel steel. At least two adjustment holes are symmetrically arranged on the two connectors. The adjustment holes are composed of three diamond holes arranged in sequence. The adjustment holes on the two connectors are locked and fixed with the mounting holes on the vertical channel steel and the transverse channel steel by fasteners. The fasteners can be adjusted and positioned by adjusting grooves. In this application, when assembling and fixing by bolts and adjustment holes, traditional cylindrical bolts are not stressed or only stressed in a single direction in the multi-diamond adjustment holes and square mounting holes, which makes the connection between the vertical channel steel and the transverse channel steel easy to loosen, affecting the overall stability of the support and hanger.

[0011] The beneficial effects of the utility model are embodied in:

[0012] In the utility model, square positioning blocks are arranged at both ends of the positioning screw, and the positioning blocks are embedded in the mounting holes and the adjustment holes, so that the positioning blocks of the screw can be fully stressed, which can increase the stress strength by 30% and increase the stability of the support and hanger assembly structure.

[0013] In the utility model, since the positioning blocks on the positioning screw are distributed at both ends, when the height of the transverse channel steel needs to be adjusted, the position of the positioning screw in the adjusting hole can be adjusted up and down by displacing the positioning screw laterally a short distance and making the square positioning block separate from the adjusting hole and the mounting hole. Compared with the positioning screw which is a square as a whole, there is no need to pull out the entire positioning screw, the operation is simple, and it is convenient for installation and adjustment.
