[0002] Building reinforcing steel bar refers to various reinforcing steel bars, steel wires and the like used in reinforced concrete. Reinforcing steel bars are divided into non-alloy steel reinforcing steel bars, low-alloy steel reinforcing steel bars and alloy steel reinforcing steel bars according to steel type. Reinforcing steel bars are divided into hot-rolled reinforcing steel bars, heat-treated reinforcing steel bars, after-heat-treated reinforcing steel bars and cold-rolled reinforcing steel bars according to production process. Reinforcing steel bars are divided into smooth round reinforcing steel bars and deformed reinforcing steel bars according to shape. Reinforcing steel bar bundling is an important work in building construction process. In concrete structure, reinforcing steel bars play a key role in bearing tensile force. In beam, plate, column and other components, reinforcing steel bars can be placed in the correct position according to design requirements through bundling. Taking beam as an example, if the position of bottom tensile reinforcing steel bar is not accurate, it may not effectively exert its tensile performance when bearing load, thereby affecting the load-bearing capacity of beam. For longitudinal reinforcing steel bars in column, bundling can keep them in the correct axial position. If the position of longitudinal reinforcing steel bars deviates, it may cause eccentric force of column when bearing pressure, thereby reducing the stability and load-bearing capacity of column.

[0003] In the process of reinforcing steel bar bundling, reinforcing steel bars need to be bundled and shaped before pouring due to the distribution of reinforcing steel bars in building structure. Reinforcing steel bars are easy to spread during bundling, so reinforcing steel bars need to be limited to facilitate bundling. The existing bundling positioning is mostly fixed square frame, which cannot be conveniently moved with bundling, and cannot be adjusted in size, thereby reducing the convenience of use. Therefore, a positioning frame for building reinforcing steel bar bundling is proposed. CONTENT OF UTILITY MODEL
