Background
In the field of building construction, maintenance of steel structure buildings such as trestle and footpath is an important link for ensuring safety and prolonging service life. These structures typically require periodic inspection and maintenance after construction is complete. In particular, the steel structure of the lower surface of the trestle is more complex in maintenance work due to the fact that the position of the steel structure is special.
The traditional maintenance method comprises the step of using a climbing vehicle, and the method can directly reach the lower surface of the trestle for maintenance. However, this approach is limited by the road under the trestle, especially in narrow or heavy traffic areas, where the use of the climbing vehicle is greatly limited. Furthermore, the use costs of the climbing vehicle are also relatively high, which increases the economic burden of maintenance work.
Another maintenance approach is to use a cradle, which requires lifting in conjunction with the car, which, while reducing the impact on the underlying road, has its limitations. For example, a construction site requires a sufficient space to install the car hoist, and stability and safety of the cradle also requires special attention. In addition, the time schedule of construction also needs to take into account the complexity and time consumption of the hoisting operation.
Therefore, there is a need to design a progressive construction platform for the underside of a trestle.
