Problems solved by technology

Among them, the Hanaor geodesic projection method is limited to use in the welded or riveted reticulated shell structure of the triangular configuration ( image 3 ), it is difficult to meet the requirements of rapid assembly of large-span single-layer spherical reticulated domes
[0003] The structures built by the above two methods have been widely used, but the design calculations are complicated, there are many types of components, and there is no vertical member perpendicular to the ground, which makes it difficult to install conveniently during the construction process, making the assembly process of the structural reticulated shell complicated, and Hanaor’s The components in the single-layer spherical reticulated shell structure are all connected by welding process, the construction period is very long, and the quality of on-site welding is difficult to guarantee

Embodiment Construction

[0028] Attached below Figure 5-18 , detailing the structure of the present invention and its installation method.

[0029] A rapidly assembled hemispherical shelving reticulated shell structure supported by vertical rods is characterized in that the hemispherical shelving reticulated shell structure includes: a hemispherical main body reticulated shell, a base node seat, and a shed plate.

[0030] The hemispherical main reticulated shell is based on the topological expansion of the 32-hedron variant plane primitive, and the geodesic projection method of Hanaor's direct expansion of the 20-hedron spherical primitive is replaced by the establishment of "node chord and surface angle sum" and its spherical mapping transformation method , at the same time select the specific primitive side length ratio and subdivision parameters to form a specific polyhedron series with the characteristics of upright members, so as to realize the topological design of single-layer hemispherical re...

Abstract

The invention relates to a semispherical roof panel reticulated shell structure with vertical rod supporting for quick assembly. The structure consists of a reticulated shell body, a base node seat and a roof panel, wherein the reticulated shell body adopts an icosidodecahedron, the icosidodecahedron is used as a foundation and is obtained through topology mapping conversion, and the reticulated shell body consists of node seats and movable joint connecting rods. The quick and convenient installation is realized through the thread connecting method. The reticulated shell body and the base node seat are connected through vertical connecting rods, an anchoring hole plate is arranged in the outer normal direction of a grounding node joint of each vertical rod, the semispherical reticulated shell is fixedly arranged on a base beam and a ground foundation by positioning anchor rods through anchoring holes, and the performance of resisting strong wind and snowstorm is improved. The span of the semispherical roof panel reticulated shell structure can be adjusted by steps, and the installation and erection of the structure on site can be started from the rods vertical to the ground, and are sequentially and upwards connected, so the construction is very convenient and quick. The structure can be used for large-span exhibition gypsums, equipment and facility storage warehouses, relief medical care centers and material centers which require quick construction.

Description

technical field [0001] The invention relates to a special design method for a spherical polyhedron single-layer reticulated shell based on topology, space geometry and structural mechanics of the bar system, in particular to a hemispherical shed plate reticulated shell structure with vertical bar supports that can be quickly assembled , belonging to the technical field of structural engineering. Background technique [0002] The construction method of the spherical reticulated shell structure, which has been widely used at present, was proposed by the Israeli scholar Hanaor. There are two construction methods: one is the longitude and latitude method with a quadrilateral configuration ( figure 1 ); the other is a geodesic projection method with a triangular configuration based on the icosahedron ( figure 2 ). Among them, the Hanaor geodesic projection method is limited to use in the welded or riveted reticulated shell structure of the triangular configuration ( image 3 ...
