Description
Technical Field
The invention relates to a temporary bearing device for building construction.
Background
The building construction refers to production activities in the engineering construction implementation stage, is the construction process of various buildings, and also can be a process of changing various lines on a design drawing into a real object at a specified place. The method comprises foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction and the like. The site of the construction work is called a "construction site" or "job site", also called a worksite.
At a building construction site, an enclosing wall needs to be built, the construction site is protected from the outside through the enclosing wall, a vehicle inlet and a vehicle outlet are arranged at the enclosing wall, the ground at the vehicle inlet and the vehicle outlet often sinks to form various pits, so that the passing vehicle jolts, the pits have little influence on driving for large-scale loading vehicle types, but the pits often cause the vehicle to be incapable of running or support the bottom for small-scale vehicle passing.
Therefore, in the conventional treatment, steel plates are placed on a traffic lane of a vehicle, and the steel plates are used as a roadbed, but the steel plates deform after bearing pressure, so that upper and lower malposition is generated between two adjacent steel plates, and the tires of the vehicle are greatly damaged.
Therefore, the temporary bearing device for building construction is developed according to the existing steel plate, and is designed to effectively bear the running of vehicles, reduce deformation and avoid dislocation.
