Floating Latticework

Abstract

A floating latticework is suitable for a latticework, a truss-frame structure and a net-shell structure over water. The floating latticework is the combination of a latticework (1) and a floating structure (2), or members of the latticework (1) in themselves are able to float. The floating structure (2) makes the latticework (1) floated over water, the surface of upper chords of which is in form of a platy structure or covered and fixed with a platy structure, as a plane used for loading. There is an advantage that the space-structure floating body is less influenced by wind and wave, which go through its space. A ship structure and a cofferdam structure are parallel solutions with the above solution. Their skeletons are net-shell structure, wherein they are provided with high structural strength.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a spatial lattice structure, and more particularly to a grid structure, a lattice truss structure, and a reticulated shell structure for use above water.[0003]2. Related Art[0004]It is well known that spatial lattice structures include grid structures, lattice truss structures, and reticulated shell structures, which have been widely applied to various places such as gas stations, stadiums, large plants, and warehouses to serve as roof surfaces. The grid structures, lattice truss structures, and reticulated shell structures are assembled by special rod members and joints manufactured in factories through mass production and supported by a plurality of upright posts made of concrete or steel structures fixed on the ground. A grid structure, lattice truss structure, or reticulated shell structure is fixedly connected to supporting posts at some joints of a lower chord, which can form a lar...

AI Technical Summary

Benefits of technology

[0064]The floating latticework and floating reticulated shell structure make full use of the sufficient rigidity of the lattice structure. A grid structure or a lattice truss structure is used as skeletons of a box-shaped, flat-plate-shaped, or flat-plate-shaped VLFS, or a liquid cargo ship. A reticulated shell structure is used as skeletons of a ship body structure and a cofferdam structure to achieve a high rigidity and strength. Especially for very large ships and vary large cofferdam structures, the sufficient rigidity of the reticulated shell structure can be sufficiently utilized, thus enabling the very large ships to overcome the torsional moment effect on the ship body caused by the waves and enabling the very large cofferdam structure to overcome the huge water pressure underwater.

[0065]Since the lattice structure is an assembly structure with a high industrialization degree, when using the floating latticework as a floating structure and using a double-layer reticulated shell structure as a ship body structure, it can improve the industrialization degree of floating structures and ships and further accelerate the shipbuilding process. Moreover, the difficulty for manufacturing very large ships can be reduced, thereby making the manufacturing of VLFSs become much easier.

Problems solved by technology

However, the current spatial lattice structures with the spaces provided there-below being utilized can only be applied on the ground, instead of being applied over water.
