Description

Technical Field

[0001] The utility model relates to the field of stadium top steel structure construction, in particular to a rooting node connection structure of purlins on the roof of a large stadium. Background Art

[0002] The double-layer grid structure (including grid structure and double-layer grid shell structure) has a beautiful appearance and can make full use of the internal space of the building. It is widely used in large public buildings such as gymnasiums, exhibition halls, and terminals. The bolt ball node is a more commonly used node form in this type of structure.

[0003] The mechanical performance of the double-layer grid structure is proportional to the grid height. Therefore, in order to increase the safety and economy of the main structure, the grid height of the main structure is often required to be higher. At present, the purlins of the roof system in large venues are often connected to the nodes of the main structure through support plates, so a larger installation height is required. In large venues, the maximum building elevation and the internal net height are often limited, which causes the installation height of the roof system to conflict with the grid height of the main structure in space. This is to overcome the technical problem of the difficulty of centralized connection of multiple components such as purlins and steel pipes.

[0004] Based on this, in order to ensure the safety of the main structure and at the same time guarantee the installation of the roof system, a rooting node connection structure for the roof purlins of a large venue is urgently needed in the project. This node can be directly connected to the bolt ball node, and the required installation height is relatively small, so as to solve the problem of conflict between the installation height of the roof system and the grid height of the main structure in space in the existing technology.
