Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] The large roof truss 1 is a cage system composed of 3 vertical trusses and 2 horizontal trusses, supported on two factory building columns (column spacing ≥ 100m), connected with the lower truss 2 through crane truss 4 and diagonal brace 5, The lower truss 2 is a cage system composed of 2 vertical trusses and 2 horizontal trusses, and both ends of the lower truss 2 are also supported on the factory building columns. The crane beam 3 is supported on the top of the lower truss 2 .

[0017] The span of the crane girder can be determined according to the 2 sections of the lower truss, and the span is relatively small. This kind of workshop structure transmits the load of the crane to the large roof truss 1 through the crane beam 3 and the crane truss 4. The space of the large roof truss 1 is relatively small, and when the span is large, the height and width of the truss...

Abstract

The invention disclose a crane girder and roof supporting structure with span greater than or equal to 100m which belongs to the fixed construction technical field. The invention is characterized in that the roofing girder is supported on two factory rods with rod distance greater than or equal to 100m that is connected with lower grinder via an overhead crane and a diagonal bracing and both ends of the lower grinder are supported on the factory rods. The grinder is supported at top of the lower grinder. The invention, with span of crane girder greater than or equal to 100m, can solve supports of the crane girder system and the roof system. The invention does not only satisfy normal operation of the crane to improve manufacturing efficiency of production line, but also ensure security of the factory house system and practicability of the construction. The invention is novel in structure with advanced technology, secure and reliable, which can be applied to support structure of grinder system and roof system with especially big span.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings, and discloses a crane beam and a roof supporting structure, in particular a crane beam and a roof supporting structure with a span ≥ 100m. Background technique [0002] Due to the requirements of the process, large-scale workshops usually need to pull columns between the spans to meet the requirements of horizontal operation of process equipment or transshipment of finished products. With the advancement of modern technology and technology, the requirements for factory buildings are also getting higher and higher. The requirements for the column distance of the factory building are also increasing. [0003] After the column is pulled out, the column distance is relatively large. When the span of the crane girder is too large (span ≥ 100m), the traditional method is to use a box girder to meet the requirements of strength and deformation. However, the height and width of the box crane gi...
