SPACE TRUSS SUPPORT DEVICE IN LARGE-SCALE TOWER

摘要

The invention discloses a space truss support device in a large-scale tower, the large-scale tower is provided with a foundation beam therein, pillars are distributed on the surface of the foundation beam at intervals, both layering and horizontal support of X-direction cross beams and Y-direction cross beams are realized between the pillars and between the pillars on the periphery and a tower body, and the X-direction cross beams and the Y-direction cross beams of all layers horizontally support functional members inside the tower respectively. The device consisting of the foundation beam, the pillars, the X-direction cross beams and the Y-direction cross beams has the characteristics of large intensity, good rigidness and small flexibility, in particular, the multi-pillar structure of the device achieves the division of the existing large-span long cross beam into small-span short cross beams, thus high levelness of tower tray can be guaranteed. With strong resistance to the impact of high-speed variable gas load, the device can effectively avoid the vibration accident caused by the impact, and in particular, a baffle in the structure is a segmental short baffle so as to avoid resonant vibration owing to the impact and guarantee long-term stable operation of the tower. The invention has the prominent advantages of reducing the manufacturing and installation difficulty as well as the investment of tower support device.
