Abstract

The invention relates to a steel reinforcement framework protective layer adjuster which comprises an adjusting steel plate and an adjusting shaft;, the adjusting steel plate is arranged between two steel reinforcements of a steel reinforcement framework; the adjusting shaft is connected to the adjusting steel plate in a threaded mode; a threaded hole is formed in the middle of the adjusting steelplate, and the adjusting shaft comprises an end, a connecting shaft and an adjusting handle. The tail of the end is fixedly connected with one end of the connecting shaft, the other end of the connecting shaft is fixedly connected with the adjusting handle, external threads are formed in the periphery of the connecting shaft, the adjusting shaft is connected to the adjusting steel plate through matched threads with the threaded hole, and the depth of the adjusting shaft penetrating through the threaded hole of the adjusting steel plate is changed; the adjusting steel plate presses the steel reinforcements of the steel reinforcement framework to adjust the position of the steel reinforcement framework.

Description

technical field [0001] The invention relates to a device for adjusting the thickness of a steel frame protective layer of bridge piers, pier columns, cover beams and reinforced concrete structures, in particular to a steel frame protective layer adjuster. Background technique [0002] With the rapid development of my country's economy and the rapid improvement of comprehensive national strength, the rapid development of my country's transportation industry, various large-scale engineering constructions are advancing by leaps and bounds, and the scale of engineering construction and construction is getting larger and larger. Engineering construction requires concrete engineering to have excellent physical quality and excellent apparent quality. Concrete works are required to meet the design requirements of durability and normal service life. Improving the physical quality, apparent quality and durability of the project is the key and core of design and construction control. ...
