Assembly-type node of cable strut structure

Abstract

The invention discloses an assembly-type node of a cable strut structure. The assembly node consists of a node central body, an ear plate, a node cover plate and a node cover plate bolt; a slot with threads is formed in the upper surface of the node central body, and a bolt hole which is connected with the node cover plate is formed in the lower surface of the node central body; a clamping groove which is matched with the shape of an outer ear plate is circumferentially formed in the node central body and used for being connected with the ear plate; a pin hole is formed in the outer edge of the ear plate and used for being connected with a pulled part; after the ear plate is clamped into the clamping groove of the node central body, the ear plate is completely fixed by utilizing the bolt to penetrate through the node cover plate. According to the assembly-type node of the cable strut structure, on the premise of guaranteeing the stress performance, the factory machining and in-situ assembling and construction of the node can be facilitated by virtue of the standardization of partial assembly parts, the type of the node in the structure is also reduced, the construction progress of the structure is accelerated, and the construction cost of the structure is reduced. The assembly-type node is mainly used for a spatial cable strut structure, a small-sized mechanical structure and model structures.

Description

Technical field [0001] The invention relates to a tension structure node, in particular to an assembled node of a cable-strut structure, and its application range includes a cable-strut structure, a small mechanical structure and a model structure. Background technique [0002] In recent years, tension structures have been widely used due to their excellent properties of light weight and high load-carrying capacity. However, the complex connection nodes have been restricting the further development and application of this kind of structure. With the continuous improvement of building structure functions and the diversification of appearance, higher requirements are put forward for the connection nodes between components. The connection nodes used in the traditional cable-strut structure mainly include casting nodes and welded nodes. The nodes are heavy in weight, complex in structure, and high in manufacturing and installation costs. In addition, there are many types of jo...
