Background

Reinforced concrete, often referred to as reinforced concrete for short in engineering. It is a composite material which is formed by adding reinforcing mesh, steel plate or fiber into concrete and works together with the composite material to improve the mechanical property of concrete. In one of the most common forms of stiffening concrete, the 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 micro-opaque lattice structure to wrap and bind the aggregate into a monolithic structure. Concrete structures generally possess a relatively strong compressive strength (about 3,000 psi, 35 MPa). However, the tensile strength of concrete is low, usually only about one tenth of the compressive strength, and any significant stretch-bending action causes the micro-lattice structure to crack and separate, resulting in structural failure. However, most structural members have a requirement for tensile stress, so that the concrete without reinforcing bars is rarely used in engineering alone, compared with concrete, the tensile strength of reinforcing bars is very high, generally more than 200MPa, so people usually add reinforcing materials such as reinforcing bars into concrete to work together with the concrete, the reinforcing bars bear the tensile force therein, and the concrete bears the compressive stress part.

But the prefabricated device of reinforced concrete who uses at present needs the manual work to demolish the baffle of spacing muddy territory after using the preparation reinforced concrete, and is comparatively troublesome result of use relatively poor, wastes time and energy to the through-hole of the prefabricated reinforcing bar that the baffle surface set up is fixed, and inconvenient shutoff as required, thereby can not control the inside reinforcing bar quantity of prefabricated reinforced concrete as required.
