  The supporting node is the tie that connects the steel space frame structure   to the enclosure structure, and is often arranged on the upper chord and side of the space frame . The deepening design of support nodes need to pay attention to the following points: (1) On the premise of meeting the force requirements, use high-strength bolts as much as possible for the connection between the support and the ball to reduce the amount of high-altitude welding on site. (2) The support top plate is best to be set in a circular shape to ensure that the support can be positioned and installed when rotating 360 degrees along the rod axis. (3) When the support height is large, in order to ensure the lateral stability of the support, it is best to install diagonal braces.

  The space frame bolt ball i s precise   finished component s, which  must be stored in a  clean place with baffles around to prevent rolling and falling off. If the site conditions permit, the steel stamp number of each ball shall be re-marked with eye-catching colors so that the ball can be found as soon as possible during construction. It is not allowed to store the ball in a muddy environment. It must be covered with a tarp on rainy days and before get off work to prevent the ball hole from being damp and rusty, which will affect the tightness of the high-strength bolts.According to previous construction experience, it will have a great safety impact on the space frame if constructed by rusty or impure bolt-ball holes.Therefore, the grid bolt ball must be paid more attention to when entering the field.

  1.  After the grid structure  is installed at high altitude, the distance between the grid and the support should be adjusted. For this reason, several groups of chain jacks should be installed above the grid for horizontal adjustment. 2.  Check the overall elevation of the grid to prevent uneven height. The elevation and horizontal distance should b ecome  one end first ly , and the steel tube should be inserted for connection. Tighten the inverted chain on one side and loosen the inverted chain on the other side so that the distance gradually becomes appropriate . 3.  After the adjusted bar on one side is fixed gradually, relax the inverted chain on the other side and continue to fine-tune the elevation of the grid on the other side. The fixed side of the grid should also be observed while adjusting to prevent open welding 。 4.  After adjusting the elevation of the grid frame  in  the other side , tighten the distance with inverted chain,...

  Snow load is also an important load on the steel structure of the space  frame. Snow load is a sensitive load for the structure of a large - span, and in many countries there have been accidents in which the steel structure of the space  frame collapses on a snowy day. Snow loads must be considered in cold areas with snow, as well as even roof distribution, uneven distribution and semi-uniform distribution. There are three main reasons that affect the distribution of snow load in the roof, namely, the wind factor, the roof shape and the roof slope factor. Snow loads that are unevenly distributed in the steel structure of the space  frame will generally have a controlling effect, and in the regulations, snow loads are generally considered at the same time as the dust  load.
