Elliptic cylinder double-curved-surface steel structure spatial reticulated shell supporting structure

Abstract

The invention discloses an elliptic cylinder double-curved-surface steel structure spatial reticulated shell supporting structure. When a reticulated shell body is installed, the reticulated shell body is placed on a base, a supporting rod assembly is located in the reticulated shell body, the peripheral wall of a supporting piece abuts against the inner wall of a middle section, and then a screw rod is rotated; when the screw rod rotates, a first moving part is driven to move upwards, a second moving part is driven to move downwards, and after the first moving part moves upwards in place, the first moving part upwards overturns and jacks up a plurality of first supporting rods, so that the lower ends of the multiple first supporting rods abut against the inner wall of the first curved surface section; and after the second moving part downwards moves in place, the second moving part turns over and downwards presses a plurality of second supporting rods, so that the upper ends of the multiple second supporting rods abut against the inner wall of the second curved surface section. According to the elliptic cylinder double-curved-surface steel structure spatial reticulated shell supporting structure, each area in the reticulated shell can be easily supported, and the supporting is stable.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to an elliptical column hyperboloid steel structure space grid support structure. Background technique [0002] Such as figure 1 As shown, there is currently an elliptical cylindrical hyperboloid steel structure reticulated shell, which is divided into the first curved surface segment, the middle segment and the second curved surface segment along the direction of its own axis, and any cross section of the reticulated shell is elliptical In the frame structure, the first curved surface segment and the second curved surface segment are arranged symmetrically with respect to the middle segment, and the diameters of the first curved surface segment and the second curved surface segment gradually increase from the end close to the middle segment to the end far away from the middle segment. The shell is a steel frame structure, which can be used for steel structure landscape mo...

Problems solved by technology

[0003] Since the elliptical cylinder hyperboloid steel space reticulated shell is a hyperboloid structure, the middle is small and the two ends are large, so, due to the limitation of the relatively narrow space in the middle, it is difficult to place the support structure inside the reticulated shell, and it is often impossible Effectively support the inside of the first curved surface segment and the second curved surface segment, so that the reticulated shell is easy to deform
