Description

TECHNICAL FIELD

[0001] The utility model relates to a stirrup equidistance binding measuring rod belongs to the technical field of building engineering. BACKGROUND

[0002] In beam structure, the stirrup and the longitudinal reinforcement are bound together to meet various requirements. From the perspective of stress performance, the stirrup can constrain the deformation of the core concrete, improve its compressive strength and ductility, bear shear force at the same time, prevent the beam from shear failure, and fix the position of the longitudinal reinforcement to ensure its accurate position in the concrete. In terms of construction technology, the stirrup and the longitudinal reinforcement form a steel reinforcement framework after binding, which is convenient for construction operation and ensures that the spacing of the longitudinal reinforcement meets the design requirements. From the perspective of durability, the stirrup can protect the longitudinal reinforcement from the influence of the external environment, prevent corrosion, enhance the integrity of the beam, and improve the seismic performance. In addition, this binding method also meets the requirements of design specifications. In short, the binding of the stirrup and the longitudinal reinforcement is of great significance to improve the stress performance, construction quality and durability of the beam.

[0003] However, during the construction and binding of the stirrup, if the construction and binding of the stirrup are not standardized, the spacing between the stirrups will not be consistent, which will cause the following problems:

[0004] 1. Insufficient shear capacity: One of the main functions of the stirrup is to bear the shear force in the beam. If the spacing between the stirrups is not consistent, the spacing of the stirrups in some areas will be too large, which will result in insufficient shear capacity in these areas. When stressed, the shear force cannot be evenly transmitted, and stress concentration may occur at the parts with too large spacing between the stirrups, which may cause shear cracks and even local shear failure of the beam.

[0005] 2. Reduced constraint effect: The constraint effect of the stirrup on the core concrete is achieved through its uniform distribution. If the spacing between the stirrups is not uniform, the constraint effect on the concrete will be reduced, especially in areas with too large spacing between the stirrups, the compressive strength and ductility of the concrete cannot be effectively improved, which affects the overall load-carrying capacity of the beam.

[0006] 3. Uneven thickness of the concrete cover: Uneven spacing between the stirrups may result in uneven thickness of the concrete cover. In areas with too large spacing between the stirrups, the longitudinal reinforcement may deviate from the designed position, making the thickness of the concrete cover thinner, and the longitudinal reinforcement more susceptible to corrosion from the external environment.

[0007] 4. Difficulty in concrete vibration: Uneven spacing between the stirrups will increase the difficulty of concrete pouring and vibration. In areas with too small spacing between the stirrups, it is difficult to insert the vibrating rod, which may result in non-compact concrete vibration, forming defects such as honeycomb and pitted surface, affecting the strength and durability of the concrete.
