[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

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with example accompanying drawing.
[0032] During specific implementation: if figure 1 and figure 2 As shown, a gasket for bolt ball joint inspection, the gasket is made of paper material; the gasket is provided with a relief hole 2 that can pass through the threaded rod in the bolt ball joint through its thickness direction, On the outside of the gasket, there is a part beyond the range of the front end of the sleeve in the bolt ball node to form a pulling part 3; there is also an easy-to-tear line 4 on the gasket, and the extension of the easy-to-tear line is located on the gasket. and the structural strength at 4 places of the easy-tear line is less than that of other positions of the gasket, the inner end of the easy-tear line is connected with the contour line of the relief hole, and the distance from the outer end of the easy-tear line to the outer contour line of the gasket Less th...

The invention discloses a gasket for inspecting a bolt ball joint and further discloses a using method of the gasket for inspecting the bolt ball joint. The gasket is characterized in that the gasketis made of a paper material; a receding hole which can allow a threaded rod in the bolt ball joint to penetrate through is formed in the gasket in a penetrating mode in the thickness direction of thegasket; a part exceeding the range of the end face of the front end of a sleeve in the bolt ball joint is arranged outside the gasket to form a pulling part; an easy-to-tear line is further arranged on the gasket, and the extending line of the easy-to-tear line is located outside the pulling part area on the gasket; the structure strength at the easy-to-tear line is smaller than that of other positions of the gasket; and the inner end of the easy-to-tear line is connected with the contour line of the receding hole, and the distance between the outer end of the easy-to-tear line and the outer contour line of the gasket is smaller than the distance between any point of the contour line of the receding hole and the outer contour line of the gasket. The gasket for inspecting the bolt ball joint and the using method thereof have the advantages that the structure is simple, the bolt ball joint can be completely inspected conveniently, the inspection efficiency can be improved, and the inspection labor intensity can be reduced.
Description
technical field [0001] The invention relates to the technical field of construction; in particular, it relates to a gasket for checking bolt ball joints and a method for using the same. 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 t...
