Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel bar adjusting tool. Background Art

[0002] With the gradual development of my country's economic construction, large-scale construction is underway all over the country, and various residential, office buildings, road projects and other projects are under construction. Among the numerous construction projects, steel bars are indispensable building materials. Steel bars are equivalent to the skeleton of the human body, playing the role of supporting and pulling the main body of the building. A large number of steel bars need to be fixed in sequence according to the engineering drawings before pouring concrete, so that the steel skeleton can be reliably fixed, which is conducive to concrete construction and other preparatory work. Among them, stirrups are a kind of steel bar used to meet the shear strength of the inclined section of the building. Stirrups are a plain round steel bar bent into a closed rectangle with a hook at the end. Because the diameter of the stirrups is large and the strength is high, and in order to improve the production efficiency of the stirrups, the existing technology uses specific bending equipment to make stirrups when producing stirrups. Patent Publication No.: CN216966110U discloses a bending device for stirrup processing, which can facilitate the bending of steel bars into a standard circle and avoid repeated measurement of the curvature of the stirrups during manual bending.

[0003] During the installation of stirrups, it is generally necessary to first use a specific bending device in the steel bar processing shed to make the stirrups into a fixed shape, then put the stirrups on the main bars, and then tie the stirrups according to the design. However, there are always cases where workers on the construction site miss the installation of stirrups. Once this situation of not following the design is discovered, it is necessary to rectify this situation within a time limit. However, after the on-site construction is completed, it is very difficult to add stirrups of the fixed shape that have been made to the beams and columns. In response to the above-mentioned situation of missing stirrups, one method currently used is to forcibly deform the processed steel bars to a certain extent and then force them into the corresponding position, but this method has low construction efficiency and difficult operation; another method is to use U-shaped stirrups instead of normal stirrups, but the U-shaped stirrups cannot achieve the effect of closing to restrain the concrete, and are easy to fall off, and the seismic effect is not good, so this method is often not allowed.

[0004] In view of the situation where stirrups are missed during the above-mentioned construction site operations, it is considered to first process the steel bars into open-type semi-finished products, and then use the steel bar adjustment tool provided by the utility model to install them on site, so as to make up for the missed stirrups.
