Description

Technical Field

[0001] The utility model relates to the technical field related to supporting devices, in particular to a metal lattice shell node plate supporting device. Background Art

[0002] With the progress of society, there are more and more types of building structures, the span is getting bigger and bigger, and the shape is becoming more and more unique. The lattice shell structure has the characteristics of the bar structure and the thin shell structure, with reasonable force, beautiful shape, and large coverage span, and is increasingly used in building structures.

[0003] At present, the connection method of the metal profile rods of the metal lattice shell structure mostly adopts the node plate connection. When the lattice shell structure is installed, it is usually necessary to set the support point of the support system on the node plate. The traditional support method is to use the frame top support of the support system to support the node plate, and set square wood between the node plate and the frame top support for support. Since the shape of the metal lattice shell structure is a non-planar structure, and the slope at the support point is also different, the traditional node plate support method not only cannot ensure the stability of the force direction of the support point, but also causes the node plate to slide easily, posing a large construction safety hazard. At the same time, the frame top support often blocks the rivet position connecting the node plate and the metal profile rod, resulting in difficulty in connecting the metal profile rod and the node plate, increasing the difficulty of construction and failing to ensure the progress of the project. For this reason, those skilled in the art have proposed a metal lattice shell node plate support device to solve the problems raised in the above background. Utility Model Content
