Three common construction methods of space frame bolt ball
The processing of space frame bolt balls is quite special. This kind of device is generally only used in the space frame structure and is not a popular device. Therefore, when constructing this device, it is necessary to formulate the model and style of the bolt ball according to the size and model of the space frame steel rod, and there are three ways to install the bolt ball. Let's take a look together. 1. Production of hollow steel balls and steel pipe rods In order to ensure the installation and quality of the space frame and space frame bolt ball processing, all hollow steel ball nodes and steel pipe rods are processed in the factory. The steel balls are processed by fetal membranes, and the raw material is 45# steel. The edge is trimmed by a lathe, and the allowable tolerance for processing is: diameter deviation ± 1mm, spherical ellipticity deviation <1mm. The allowable deviation of the length of the steel pipe rod is ± 1mm, the end face of the rod must be perpendicular t
