Embodiment 1
[0022] The following examples illustrate the possible implementation of this patent, but are not intended to limit the scope of protection of this patent, and are described first.
[0023] refer to Figure 1 to Figure 4 , which shows the first preferred embodiment of this patent. During the assembly process of the prefabricated building, the inserted steel bars of the components to be inserted are temporarily magnetically charged, and the steel fibers are adsorbed around the steel bars to form the inserted steel bars by using the principle of magnetic attraction of steel fibers. It is a "mace" shape in which the central steel fiber is attached to the surroundings, so that the steel bars and concrete in the prefabricated building nodes form a reliable bond, thereby improving the tensile strength and integrity of the prefabricated building nodes.
[0024] The specific design scheme of this embodiment is as follows:

The invention discloses a bonding method for a reinforced steel bar and concrete based on the steel fiber magnetic attraction principle, and the method comprises the steps: setting an assembly-type building component and a to-be-inserted building component, wherein the assembly-type building component is provided with a reserved node gap, and the to-be-inserted building component is provided withan insertion steel bar; setting concrete and steel fibers, and uniformly mixing and stirring the concrete and steel fibers to form steel fiber reinforced concrete; pouring the steel fiber reinforced concrete into the node gap, and enabling the insertion steel bar to be magnetized in a strong magnetic field environment to generate a magnetized steel bar; performing the inserting assembly of the to-be-inserted building component, i.e., inserting the magnetized steel bar with the temporary magnetism into the node gap with the steel fiber reinforced concrete. Through the magnetic attraction principle, the inserted steel bar will attract the steel fibers in the surrounding concrete to form a shape like a wolf's fangs mace, thereby enabling the steel bar and concrete in the node of an assembly-type building to be bonded reliably, and improving the tensile strength and integrity of the node of the assembly-type building.
Description
technical field [0001] The invention relates to a bonding reinforcement technology between steel bars and concrete, in particular to a method for strengthening the bonding between steel bars and concrete based on the principle of steel fiber magnetic attraction. Background technique [0002] Prefabricated buildings have been vigorously promoted at home and abroad for their advantages of short construction period, saving resources, saving costs, and less environmental pollution. In the process of assembling prefabricated buildings, the node link processing between two connecting components affects the entire building structure. key. The joint is the weak link of the whole building structure, and its tensile strength is weaker than other parts of the building structure; the integrity of the joint is low, which leads to the decline of the seismic performance of the structure; during the service process of the building structure, damage often occurs at the joint, and the failure...
