Spherical joint free-soldering device

Abstract

The invention relates to a connecting device, particularly relates to a device for building welding-free net rack connection and hanging spherical joint welding-free connection and aims at solving the technical problem of providing a spherical joint welding-free connecting device which is simple and reasonable in structure and enables installation and hanging at spherical nodes to be convenient. According to the technical scheme, bottoms of a left half circular ring and a right half circular ring are hinged; tops of the left half circular ring and the right half circular ring are provided with long holes; a pin shaft runs through the left half circular ring and the right half circular ring to be inserted into the long holes; the bottoms of the left half circular ring and the right half circular ring are provided with extension rods; bottom circular ring surfaces of the left half circular ring and the right half circular ring are vertically provided with a connecting piece; the two connecting pieces are provided with long hole grooves; sliding rods are arranged inside the long hole grooves; hanging rods are arranged on the sliding rods; end portions of the two extension rods are provided with pulling rods in a hinging mode; the other ends of the two pulling rods are hinged to the sliding rods. The spherical joint welding-free connecting device is simple and reasonable in structure and widely applied to connection of spherical nodes of the spherical net rack.

Description

technical field [0001] The invention relates to a connection device, in particular to a spherical node welding-free connection device used for connection and suspension of architectural spherical grid frames. Background technique [0002] Large-space and long-span building structures such as airport terminals, station waiting rooms, workshops, and warehouses often use spherical grid rock wool sandwich heat-insulating profiled steel roofs. The roofs of this structure are equipped with suspended ceilings to decorate air ducts. Install equipment, and at the same time reduce the effective indoor floor height, which is conducive to energy saving. [0003] At present, when the spherical grid is installed on the ceiling, the decorative ceiling cannot be directly connected to the ball nodes of the grid. [0004] Most of them are hoisted on the lower suspension rod of the spherical grid, which will destroy the stress system of the spherical grid, which has potential safety hazards a...

Problems solved by technology

[0003] At present, when the spherical grid is installed on the ceiling, the decorative ceiling cannot be directly connected to the ball nodes of the grid.

[0004] Most of them are hoisted on the lower suspension rods of the spherical grid, which will destroy the force system of the spherical grid, pose a safety hazard, and the construction is inconvenient
