Lotus-shaped single-layer latticed shell structure

Abstract

The invention discloses a lotus-shaped single-layer latticed shell structure which comprises oblique arc-shaped main arches arranged according to a lotus petal shape. Multiple lotus petal structures formed by the oblique arc-shaped main arches equally divides a latticed shell curved surface into a plurality of symmetrical zones, and the bottoms of the lotus petal structures formed by the oblique arc-shaped main arches are respectively connected with a support ring rod to form a whole structure. The lotus-shaped single-layer latticed shell structure combines with the structural morphology bionics, has obvious shell stress features, is clear and direct in radial and annular force transfer, high in stress efficiency and large in rigidity and facilitates decreases of material usage amount. The structure is composed of arc rods like lotus petals in shape, is light in structural style, novel and attractive and has a very good aesthetic effect. In addition, the arranged rods can be flexibly increased or decreased according to the actual situation, structural configuration is flexible and varied, and the lotus-shaped single-layer latticed shell structure has the wide applicability in large public buildings having higher requirements for aesthetic functions of building structures, for example, exhibition halls, art galleries and museums.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a lotus-shaped single-layer reticulated shell structure. Background technique [0002] The earliest hemispherical reticulated shell structure is a ribbed reticulated shell, with several planar ribs arranged in the radial direction to form a thrust system; in order to bear the circumferential force of the spherical reticulated shell, it is considered to connect the annular purlins of the ribbed reticulated shell with the ribs to form a rigid system , forming a ribbed reticulated shell. In 1863, German engineer Schwedle (Schwedle, J.W.) developed and perfected the above structure, and proposed that in addition to connecting radial ribs and horizontal broken line rings, each system grid should be divided into small triangles by diagonal bars to strengthen the structure , and improve the ability to bear asymmetric loads, called "Schweidler reticulated shell".

Problems solved by technology

Since the beginning of the 21st century, with the enrichment of people's material life and the gradual improvement of aesthetic requirements, the above-mentioned characteristics of traditional reticulated shells, such as the dense number of rods, the single grid form, and the lack of structural aesthetics, have been magnified. A new type of space structure with rich grid shapes and beautiful structure shapes, striving to create a sense of structural beauty and enrich the form of space structures
