Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced concrete engineering, in particular to a reinforcement spacing control device. Background Art

[0002] Concrete is a mixture of cement (usually Portland cement) and aggregate. When a certain amount of water is added, the cement hydrates to form a microscopic opaque lattice structure that wraps and combines the aggregate into an overall structure. Usually, concrete structures have strong compressive strength, but the tensile strength of concrete is low, usually only about one-tenth of the compressive strength. Any significant tension and bending will cause the microscopic lattice structure to crack and separate, resulting in structural damage. Most structural components have the need to be subjected to tensile stress, so unreinforced concrete is rarely used alone in engineering. Compared with concrete, the tensile strength of steel bars is very high, generally above 200MPa, so people usually add reinforcing materials such as steel bars to concrete to work with it, with the steel bars bearing the tensile force and the concrete bearing the compressive stress part.

[0003] As an important inspection item for reinforced concrete projects, the control of steel bar spacing can not only ensure good adhesion between concrete and steel bars, but also avoid affecting the pouring and vibration of concrete due to lax control of steel bar spacing. Therefore, strict control of steel bar spacing is a very important process in steel bar installation. Therefore, a steel bar spacing control device is needed. The steel bars can be clamped by angle steel columns, which not only facilitates the arrangement of steel bars, but also plays a certain fixing role and facilitates the connection of steel bars. The angle steels in the vertical and horizontal directions are fixed and connected as a whole, which can ensure the stability of the connection between the angle steels. At the same time, the control of steel bar spacing directly guarantees the quality of reinforced concrete projects. Utility Model Content
