Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering detection equipment, in particular to a steel strand detection device. Background Art

[0002] External prestressing is a method of reinforcing structural components or the entire structure using externally applied prestressed steel tie rods or steel struts. Its characteristic is that prestressing forces the added components (such as tie rods or struts) to bear force, changing the internal force distribution and reducing the stress level of the original structure. This completely eliminates the stress-strain hysteresis characteristic of conventional reinforced structures.

[0003] The external prestressing reinforcement method is widely used in the field of bridge reinforcement engineering, especially for old and dangerous bridges on ordinary national and provincial trunk roads. Prestressed tendons (usually prestressed steel strands) are laid on the surface of structural components (such as T-beams) and appropriate prestress is applied so that the prestressed steel strands work together with the reinforced concrete at the anchor end, thereby significantly enhancing the bending resistance and stiffness of the original T-beam components, reducing the deflection of the components under the same load, and improving the ultimate bearing capacity of the components. The use of the external prestressing reinforcement method does not have the defect of stress lag, the construction process is simple, the cost is low, and the damage to the original beam structure is small. It can be done without affecting the clearance under the bridge and without increasing the road surface elevation. However, in the actual construction process, due to factors such as the complexity of the on-site environment and the high precision requirements of construction operations, the layout of the steel strands often deviates from the design requirements. It is necessary to accurately determine the position of the original beam steel strands to avoid accidental contact with the steel strands during the drilling construction of the anchor end of the T-beam external prestressing reinforcement project, which may cause damage to the steel strands. Therefore, it is necessary to find an intuitive and effective method to position and lay out the prestressed steel strands. At present, the non-destructive detection equipment for concrete in the construction of T-beam external prestressing reinforcement is a rebar scanner, which is used to detect the distribution, diameter, direction of the steel bars in the concrete structure, and the thickness of the concrete cover. However, its detection depth is limited and cannot meet the detection requirements of the steel strands.

[0004] In order to solve the above problems, a steel strand detection device is proposed based on structural radar. Utility Model Content
