Description

Technical Field

[0001] The utility model relates to the binding construction of beam-column steel bars, in particular to an auxiliary bracket for positioning the binding of bent column steel bars. Background Technique

[0002] When constructing bent columns, it is necessary to first bind the column steel bars and then pour the concrete. Due to the large cross-sectional size and high height of the column, it is difficult to position and bind the steel bars. As the binding height increases, the longitudinal steel bars of the column are extremely prone to displacement, bending and other situations. The longitudinal steel bars mainly bear the longitudinal load on the column, and their binding quality will directly affect the mechanical properties of the structure.

[0003] For this reason, engineers have proposed an auxiliary bracket for positioning the binding of steel bars, and several short steel bars are welded around a rectangular frame to assist in positioning the binding of the longitudinal steel bars of the column. During operation, the longitudinal steel bars are closely attached to the outer side of the rectangular frame and are clamped between the short steel bars. After the longitudinal steel bars and stirrups are bound, the positioning bracket is lifted, and then the longitudinal steel bars and stirrups are bound. The operation is cycled in turn until the column steel bars are bound.

[0004] However, there are some problems with this method during construction. Since all the steel bars are threaded steel bars, it is difficult to lift the positioning bracket, and it is extremely easy to get stuck with the column steel bars, thus affecting the on-site operation efficiency. In addition, the positioning bracket needs to be customized according to the column size and steel bar arrangement, and it is difficult to be used in other projects, increasing the construction cost. Content of the Utility Model

[0006] The auxiliary bracket for positioning the binding of bent column steel bars involved in the utility model includes a support frame and a steel bar limiting component thereon. The steel bar limiting component is fixed on the support frame, and a sliding support structure is arranged on the steel bar limiting component. The longitudinal steel bars are closely attached to the sliding support structure, and the moving difficulty of the positioning auxiliary bracket is reduced by arranging the sliding support structure.

[0007] Preferably, the steel bar limiting component is a pin shaft limiting component, which consists of a support pin shaft and a rotating sleeve. The rotating sleeve is installed on the support pin shaft as the sliding support structure. The pin shaft limiting components are arranged in pairs, and the longitudinal steel bars are clamped between the two pin shaft limiting components, so as to realize the temporary fixing and positioning of the longitudinal steel bars.

[0008] Preferably, the steel bar limiting component is a pulley limiting component, which consists of a pulley bracket and a supporting pulley. The supporting pulley is installed on the pulley bracket as a sliding support structure, and the surface of the supporting pulley is concave. The longitudinal steel bar is clamped into the groove, so as to realize the temporary fixing and positioning of the longitudinal steel bar.

[0009] Preferably, the steel bar limiting component is fixed on the supporting frame by welding.

[0010] Preferably, the steel bar limiting component is fixed on the supporting frame by installation bolts. The tail of the steel bar limiting component is provided with installation bolts, and the supporting frame is provided with installation holes.
