Description

TECHNICAL FIELD

[0001] The utility model relates to a stirrup binding tool in building construction, in particular to a portable stirrup bending device. BACKGROUND

[0002] In building engineering, the stirrup is generally used to fix between double-layered steel bars, and the design specification refers to GB50204-2015 "Concrete Structure Engineering Construction Quality Acceptance Specification". When the tie bar is used as a single limb stirrup or beam waist tie in the beam-column composite stirrup, the bending angle of the two ends of the hook should not be less than 135°.

[0003] In the field construction, a large number of stirrups are bent to 135° at the two ends in advance by using a numerical control steel bar processing machine, and then installed on the steel bar framework. However, this method has low construction efficiency and is difficult to install. After the main steel bar of the steel bar framework is formed, the installation of the stirrup is relatively cumbersome and time-consuming and laborious. When the beam stirrup is transversely inserted into the main steel bar, the flowability is not enough, and manual pulling is required, which may cause local deformation of the steel bar or large angle deviation.

[0004] Another method is to bend one end of the stirrup to 135°, and then bend the other end after it is inserted into the main steel bar. After the stirrup is positioned, the end of the stirrup is bent using a wrench. However, the bending angle often cannot meet the design requirements because the existing wrenches have various types and poor construction effect.

[0005] In addition, the quality of the anti-seismic steel bar binding is high, the bending quality is unqualified, the overall structure of the steel bar is deformed, and the structural stability of the composite stirrup is easily affected.

[0006] In order to meet the anti-seismic construction quality of the main structure and not affect the construction efficiency, a simple device for bending the steel bar is needed to realize the requirement that the two ends of the single limb stirrup are 135° hooks after the on-site installation is completed.
