Embodiment Construction
[0026] The structure of the present invention will be described below in combination with the processing process.
[0027] Each component of the present invention is processed by mechanical processing or first casting and then mechanical processing. In order to ensure the accuracy, each part can be processed by machining, or a combination of casting and machining.
[0028] In this embodiment, the perforated welding ball (1) is provided with screw holes in 5 directions according to actual needs, and the specific number and directions can be adjusted according to actual conditions, such as Figure 12 shown. The length of the thread section of the outer joint (6) with external thread should be greater than or equal to the length of the thread section of the sleeve (5) with internal thread. The inner joint (2) with external thread has the same diameter as the outer joint (6) with external thread.
[0029] Put the inner lining ring (3) on the inner joint (2) with external thread...

The invention discloses an error-adjustable space grid structure sleeve node. The error-adjustable space grid structure sleeve node comprises a tapping welding ball, an internal connector with an external thread, a sleeve with an internal thread, an external connector with an external thread, an internal lining ring and an external lining ring, wherein the tapping welding ball is a hollow ball anda plurality of reserved holes are formed in the ball; the internal connector with the external thread can be connected with other members through the reserved holes; the internal lining ring is arranged between the internal connector with the external thread and the tapping welding ball; the external lining ring is arranged between the tapping welding ball and the sleeve with the internal thread;the sleeve with the internal thread is connected with the internal connector with the external thread and the external connector with the external thread through a thread and is fixed with the tapping welding ball through the internal lining ring and the external lining ring and. The node disclosed by the invention can be produced in an industrial standardization manner; in a field construction process, the connection of rod parts can be finished only by rotating the sleeve. According to the node disclosed by the invention, field welding is avoided so that the difficulty of field installationis reduced, and an installation process of a net frame and a net shell is simpler and more convenient through the node.
Description
technical field [0001] The invention relates to a sleeve node of an adjustable error space grid structure, which belongs to the field of building steel structures. Background technique [0002] The space grid structure system is a curved surface space structure composed of many rods passing through nodes according to certain rules. This type of structure has the advantages of good mechanical performance, high structural stability, simple and quick construction, etc., and has been widely used in various industrial and civil buildings. With the development of my country's economic and social levels, the construction industry is facing huge problems such as increased labor costs. Improving the level of building assembly can effectively improve production efficiency. At present, although my country's spatial grid structure and other systems can achieve standardized production, on-site assembly will take a long time, resulting in higher costs. [0003] Commonly used nodes in ex...
