Abstract
The invention provides a control device for the flatness and elevation of a large area wear-resistant floor and a construction method. The device includes a support base, the support base is fixed ona reinforcing mesh in a construction site, the surface of the upper end of the support base is provided with a bolt hole, the bolt hole is internally provided with an anchor bolt, the anchor bolt runsthrough a steel plate, the lower end of the steel plate is provided with an adjusting nut which is in threaded connection with the anchor bolt, the upper end of the support base is provided with a box iron, a web of the box iron makes contact with the surface of the upper end of the support base, the surface of the web of the box iron is provided with a bolt hole, and the anchor bolt runs throughthe web of the box iron. The device effectively controls the flatness and elevation of the large area wear-resistant floor, the construction means of the flatness and elevation control in the large area floor construction is effectively improved, the technical benefits are maximized, and the problem is solved that a 6 m guiding rule is used for leveling control according to the elevation, the control precision is thus low and the standard requirements are not easily met in an existing construction method is solved. Rework processes are reduced, and quality of a project is improved.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a device for controlling the flatness and elevation of a large-area wear-resistant floor and a construction method. Background technique [0002] Since its appearance in the 1970s, wear-resistant flooring has been rapidly popularized in Europe and the United States, and has become a perfect replacement product for terrazzo floors. In the late 1980s, wear-resistant flooring was the first choice for developed countries. [0003] Most industrial plants, heavy-duty machinery factories, auto repair shops, warehouses, squares, docks, parking lots, warehouse-style shopping malls, supermarkets, etc., especially in areas where vehicles walk. Carborundum ground hardener is composed of mineral alloy aggregates with a certain particle size distribution, special cement, other admixtures and admixtures. It can be used after opening the bag, and it can be evenly spread on the s...
