Embodiment Construction

[0052] The invention provides a screw square hoop forming device for efficiently making a screw square hoop. The screw square hoop forming device of the present invention is preferably used to replace the conventional method of gradually bending straight steel bars into steel bar coils without spacing, and then pulling the head and tail of the steel bar coils apart with a machine to create spacing. The screw square hoop formed by the screw square hoop forming device of the present invention is preferably used in reinforced concrete structures in construction industry, construction industry, traffic road engineering, aquatic product engineering and the like. However, in different embodiments, the screw square stirrup of the present invention can also be used as a stirrup structure of a building, such as a plate-shaped floor structure or a composite structure of screw stirrups, or as other structural units of a building.

[0053] As shown in FIG. 1 , the square hoop forming devi...

Abstract

The invention provides a screw square hoop forming device and a forming method thereof, comprising a central rotation part, a first rotation part, a plurality of axial enwinding parts and a bar bending device. The central rotation part and the first rotation part are arranged in parallel; the bar inlet side and a plurality of axial enwinding parts are arranged at the periphery of the central rotation part; wherein, each axial enwinding part is connected with the first rotation part in a detachable way; furthermore, the first rotation part can move along the axial direction correspondingly to the central rotation part; the bar bending device is arranged at the bar inlet side and comprises a positioning part and a bar pressing part; when bars extend into the central rotation part from the bar inlet side, the positioning part clamps the bars and the bar pressing part moves correspondingly to the positioning part and presses the bars to form a bending part; the bending part is buckled with the axial enwinding parts under the driving of the rotation of the central rotation part.

Description

technical field [0001] The present invention relates to a square hoop forming device and a forming method thereof; specifically, the invention relates to a square hoop production device for efficiently forming square hoops. Background technique [0002] With the improvement of structural strength requirements for various buildings, the design strength provided by the skeleton composed of spiral steel bars has been paid attention to by the structural design of the engineering field. The so-called spiral stirrup refers to the spiral steel bar bent into a continuous spiral as the stirrup matched with the main reinforcement, which has the effect of fixing the position of the main reinforcement and providing shear strength. The cross-sectional shape of the spiral steel bar can be adjusted according to the actual design, and the more common ones are circular and rectangular. In addition to being widely used as stirrups in beam-column structures, in some large-scale or specially d...
