Abstract

The invention discloses a multidirectional error-adjustable node suitable for a suspend-dome space structure. The node comprises a bracket, adjusting pieces, vertical spacing bolts and other devices and fittings, wherein the adjusting pieces are fixed on the bracket through the vertical spacing bolts to from a node entirety; and error adjustment is realized through the adjusting pieces. The invention has the advantages as follows: three-dimensional multidirectional adjustment of the node and a lattice shell rod piece connected with the node can be carried out in the horizontal direction, the vertical direction and the axis direction of the rod piece, so that the length of the rod piece and the spatial geometric position of the node can be adjusted; and through the adoption of the node, construction errors and structural defects are reduced, the stable bearing capacity of a structure is effectively improved, and the safe use of the structure is ensured.

Description

technical field

[0001] The invention belongs to the field of civil engineering, and relates to a device, an accessory and an installation and adjustment method suitable for adjusting the length of a rod and the position of a node in a space structure of a suspend dome. Background technique

[0002] Suspension dome structure is a new type of prestressed space structure system widely used in large-span and large-space structures. In recent years, it has been widely used in public buildings such as gymnasiums, exhibition halls, theaters, auditoriums, waiting halls, etc., such as: the roof of the lobby of the business center in Tianjin Free Trade Zone, Changzhou Stadium, 2008 Beijing Olympic Badminton Stadium, Jinan Olympic Sports Center Gymnasium It has become one of the most modern and potential green load-bearing structural systems in the 21st century.

[0003] In terms of structural composition, the space structure of the suspend dome consists of an upper steel grid structu...
