Device and method for controlling thickness and flatness of concrete floor

Abstract

The invention relates to a device and method for controlling the thickness and flatness of a concrete floor. The device is characterized in that concrete is poured into a mould to form a concrete cylinder, an iron nail is inserted into one end of the concrete cylinder, the head of the iron nail is exposed out of the concrete cylinder, and the height of the concrete cylinder is the thickness of a to-be-poured concrete floor. A manufacturing method of the device includes: pouring high-grade fine-aggregate concrete or micro-expansive fine-aggregate impermeable concrete into the mould until the concrete is parallel with a plastic tube; before the final set of the concrete, inserting the tail of the iron nail into the concrete at the opening of the tube, removing the surface plastic-tube mould 48 hours after the final set of the concrete, and continuously performing moist curing for 7 days. The method for controlling the thickness and flatness of the concrete floor includes: after a floor template is set and board reinforcing steel bars are bound, mounting the concrete thickness control device on the surface of the floor template according to controllable gap requirements so as to control the thickness of the concrete floor during concrete pouring. The practical device is simple in structure, convenient to manufacture and mount and controllable in quality.

AI Technical Summary

Benefits of technology

This technology described in this patents allows for easier customization or creating products that are both durable and resist leaks when installed on top of an existing flooring system without compromising its effectiveness over time. Additionally, by combining these technologies into one product, there're less effort required during building operations while maintaining consistently good performance levels throughout their lifetime. Overall, this new technology simplifies the process of producing strong structures made from poured cementitious material (cement).

Problems solved by technology

The technical problem addressed by this patented technology relates to controlling the thickeness or planarity of concrete floors used on buildings due to variations caused from factors like temperature changes over time (temperature fluctuations) that can cause cracks when casted into place. This issue affects both durability and performance of the final product being built upon them.
