Bolt ball node installing structure

Abstract

The invention discloses a bolt ball node installing structure, which comprises a bolt ball and a connecting rod assembly, wherein an installing plane is arranged on the bolt ball; the front end of theconnecting rod assembly is provided with a threaded rod in forward arrangement; the connecting rod assembly comprises a connecting rod and a sleeve; the sleeve is coaxially arranged at the front endof the connecting rod; the front end of the sleeve is an end part for being abutted against the installing plane of the bolt ball; the threaded rod is coaxially arranged in the sleeve and is rotatablely connected with the front end of the connecting rod; a transmission structure is arranged between the sleeve and the threaded rod, so that the threaded rod is driven to rotate by the sleeve; the front part of the threaded rod is connected in a threaded hole formed in the installing plane of the bolt ball through screw threads; the front end of the connecting rod assembly is abutted against the installing plane of the bolt ball. The bolt ball node installing structure is characterized by also comprising a gasket which is arranged between the bolt ball and the end surface of the front end of the sleeve. The bolt ball node installing structure has the advantages that the work efficiency can be improved and is high; the work intensity is reduced; the inspection quality is more stable; highersafety is realized.

Description

technical field [0001] The invention relates to the technical field of construction; in particular, it relates to a bolt ball node installation structure. Background technique [0002] Bolt ball joints are composed of bolts, steel balls, pins (or screws), sleeves, cone heads or sealing plates, and are suitable for connecting steel pipe rods, mainly used in grid structures. Bolt ball joints have a wide range of applications and can be assembled into various space rod structures. Such as grids, reticulated shells, three-dimensional trusses, towers, scaffolding, etc. It can be used for both permanent buildings and temporary buildings, which is convenient for assembly, disassembly and expansion. At present, the maximum rod tension in the domestic bolt ball joint network frame is 75t, and the maximum suspension crane is 5t. [0003] The connection construction principle of the bolted ball joint is: first, the cone head or the sealing plate with the bolt is welded to the two en...

AI Technical Summary

Problems solved by technology

[0005] At present, the inspection of the joints of the bolt ball joints relies on workers to inspect the bolt ball joints that have been randomly inspected one by one. The inspection of the bolt ball joints by random inspection can reduce the overall inspection quantity, but it cannot guarantee that each bolt ball The nodes all meet the quality requirements; and the existing inspection method is to use ordinary wrenches and rulers for inspection, because the angles between the bolt ball nodes are different, which will block the inspection and cause mutual interference when measuring the ruler; this will lead to The inspection quality is not stable enough, the entire inspection work efficiency is low, and the labor intensity is high; at the same time, the follow-up inspection of the bolt ball joint is a high-altitude operation, and there will be safety hazards
