Single Layer Box Section Surface Reticulated Shell Node

Abstract

The invention mainly discloses a single-layer box-section curved-surface reticulated shell joint. The joint comprises a round pipe in the center of the joint, stiffening plates in the round pipe, and a plurality of box-section rods. The box-section rods are connected with the round pipe in the center of the panel joint through penetration welding seams, and the round stiffening plates are added in the round pipe in the center of the joint at same positions of flanges of the box-section rods and in the middle of the round pipe in the center of the joint. The single-layer box-section curved-surface reticulated shell joint is definite and direct in force transmission, the controllability of the welding seam quality is achieved, and requirements on structure stress are fully met. Moreover, the problem of directionality of box-section components in a complex curved surface is solved, factory processing and site operation are convenient and simple, and the problem that the construction cost is increased due to the adoption of cast steel joints is solved, so that the single-layer box-section curved-surface reticulated shell joint is particularly suitable for box-section single-layer reticulated shell structures with peculiar building surface modeling.

Description

technical field [0001] The invention relates to components used for steel structure buildings, in particular to a single-layer box-section curved reticulated shell node. Background technique [0002] The rods of the traditional reticulated shell structure are mostly round steel pipes, and the internal force of the rods of the structure is mostly axial force. With the improvement of my country's comprehensive national strength, domestic building structures are developing towards larger spans, larger areas, and more complex shapes. The reticulated shell members under the new shape also bear a considerable bending moment in addition to the axial force. effect. Box-section rods are favored by more and more architects because of their good bending and torsion resistance, and their sharp edges and corners, showing good mechanical beauty. They are favored by more and more architects. The application in the structure is more and more extensive. [0003] With the popularization of ...

Problems solved by technology

At the same time, it solves the problem of directionality of box-section members in complex curved surfaces. It is convenient and simple for factory processing and on-site construction, and avoids the problem of increased project cost caused by the use of cast steel nodes. It is especially suitable for box-section units with strange curved surface shapes. layer reticulated shell structure
