Description
Technical Field
The utility model relates to a building technical field, in particular to light steel construction roof truss bottom chord supporter.
Background
The lower chord of the roof truss is one of the building components, the steel structure of the roof truss can be corroded as the usage of a steel structure factory building increases with time, particularly, the lower chord part of the roof truss is provided with the lower chord part, the lower chord bears the transmission of a force system in the whole structure, the lower chord part mainly plays a tensile stress role and mainly plays a role in strength, the sectional area of the lower chord part is reduced along with corrosion, the strength of the lower chord part is also reduced, and the strengthening and reinforcing work of the lower chord part is more important.
The traditional steel structure reinforcement mode has: and (3) methods for lightening load, changing a structural static calculation model, preventing crack propagation and the like. With the development of reinforcement technology, novel reinforcement methods such as a sleeve reinforcement method, a carbon fiber reinforcement method and a bonded steel pipe reinforcement method appear, and the common point of the methods is that the buckling resistance and stability of the structure are improved by increasing the rigidity of the structure, so that the service life of the structure is prolonged. However, because the steel net rack is stressed complexly, the steel net rack not only bears vertical load in a plane, but also bears internal force which is transmitted in the horizontal direction and meets the coordination of space deformation and displacement outside the plane, and the selection of a reinforcing method is often limited to the conditions at that time, so that the common reinforcing method is not suitable any more.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the deficiencies in the prior art and provides a support body for the lower chord of a light steel structure roof truss.
