Metal roof plate reinforcing device with monitoring function

Abstract

The invention belongs to the technical field of a metal roof plate, and particularly relates to a metal roof plate reinforcing device with a monitoring function. The metal roof plate reinforcing device comprises self-sensing reinforcing ribs, transmission lines, an upper computer and reinforcing rib fixing support seats, wherein the self-sensing reinforcing ribs are fixedly connected with the metal roof plate through the reinforcing rib fixing support seats; and the reinforcing rib fixing support seats and the metal roof plate are fixedly connected. The advantages of light dead weight, high strength, small size and high durability are realized. The large-range arrangement can be realized; two characteristics of stress and sensing are realized; and structure materials and function materialsare integrated. Before the roof plate generates defects and damage, the metal roof plate can be reinforced, the wind-uplift-resistant performance of the metal roof plate is improved, and the practical stress condition of the metal roof plate is monitored. When the wind uplift suddenly occurs, flying and scattering of wind uplift falling objects can be inhibited through the integral stress of thereinforcing rib fixing support seats and the self-sensing reinforcing ribs.

Description

technical field [0001] The invention relates to the technical field of metal roof panels, in particular to a metal roof panel reinforcing device with a monitoring function. Background technique [0002] In recent years, metal roof structures have been widely used in large-span building structures such as railway stations, airports, and stadiums due to their advantages such as light weight, good thermal insulation effect, and fast construction speed. However, since the metal roof panel is a light-weight maintenance structure, it has light weight and is easily affected by environmental loads, especially wind loads. In addition, the connection methods between the components of the roof panel usually adopt mechanical connections in the form of locking, snapping or clamping. The connection stiffness is low. Under the long-term, repeated and cumulative effects of wind loads, it is easy to cause undetectable diseases such as connection looseness and even failure of component connec...

Problems solved by technology

More importantly, because the traditional wind-proof reinforcement method is only a passive improvement of protection ability and lacks necessary monitoring measures, it is impossible to achieve long-term monitoring of the reinforcement effect, let alone early warning of wind-break accidents; especially for Some existing buildings that have undergone wind exposure accidents and have been reinforced against wind exposure cannot effectively monitor the reinforcement effect and prevent secondary wind exposure.

In addition, due to the complex causes of wind exposure, it is the result of the joint action of random environmental loads, accidental loads, and internal defects over time. It is highly random, time-varying, and sudden. It evolved, and the initial phenomenon is not obvious, making it difficult to locate the time and specific location of the wind blowing. In addition, the metal roof panel has the characteristics of low bearing capacity and large area, which makes manual maintenance difficult and is not suitable for regular inspection. , unable to achieve timely warning of wind exposure risks
