Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending, in particular to a construction site steel bar rapid bending device. Background Art

[0002] Rebar plays a primary role in supporting and reinforcing building structures. To meet specific structural requirements, such as beam bending and column connection, it must be bent into specific shapes. To improve construction efficiency and optimize workflows, it's common practice to pre-treat the rebar before it leaves the factory, precisely bending it to shape according to the design blueprint and then delivering it directly to the construction site for use. This pre-treatment step significantly reduces on-site processing time and accelerates project progress.

[0003] However, complex construction practices inevitably present unforeseen factors, such as temporary design adjustments, site constraints, and operational errors, which can lead to changes in rebar specifications. Consequently, even pre-bent rebar may not fully meet on-site construction requirements, highlighting the importance and urgency of flexibly adjusting rebar configuration on-site. Utility Model Content

The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0028] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figures 1 to 6 , is a construction site steel bar rapid bending equipment according to one embodiment of the present invention, comprising a moving frame 10, a positioning assembly 20 installed on the top of the moving frame 10, and a bending assembly 30 connected to the positioning assembly 20.

[0031] An adapter plate 11 is installed on the top of the movable frame 10 . At least three first through holes 12 are evenly spaced apart on the adapter plate 11 . The first through holes 12 are used for positioning and connecting the positioning assembly 20 .

[0032] The positioning assembly 20 comprises a bearing seat 21 connected to the mobile frame 10, a positioning block 22 slidably connected to the top end of the bearing seat 21, a screw rod 23 screwed to the top end of the bearing seat 21, and a rotating handle 24 connected to the top end of the screw rod 23. The bottom end of the screw rod 23 is connected to the positioning block 22 downward. The rotating screw rod 23 can adjust the height of the positioning block 22 to adapt to steel bars 40 of different diameters.

[0033] As shown in Figure 4 and Figure 5 The bottom end of the positioning block 22 is provided with a positioning recess 220 for matching and abutting the steel bar 40.

[0034] In the embodiment, at least three second through holes 25 are uniformly and spacedly arranged on one side of the bearing seat 21, and the second through holes 25 correspond to the first through holes 12 one by one. After the second through holes 25 and the first through holes 12 are connected by bolts and nuts, the bearing seat 21 and the adapter plate 11 can be connected.

[0035] The bending assembly 30 comprises a bending disc 31 mounted on the side of the bearing seat 21 away from the mobile frame 10, a rocker arm 32 hinged to the bending disc 31, an extension arm 33 slidably connected to the rocker arm 32, and a bending block 34 mounted in the inner end of the rocker arm 32 close to the bending disc 31. The rocker arm 32 is arranged along the radial direction of the bending disc 31.

[0036] The bending disc 31 is recessed inward along its outer periphery to form a bending groove 310 for matching and accommodating the steel bar 40. The bottom end of the bending block 34 is provided with a bending recess 340 corresponding to the bending groove 310, and the bending recess 340 is used for matching and abutting the steel bar 40. When bending, the steel bar 40 is placed on the top of the bending disc 31, the positioning block 22 presses one end of the steel bar 40, and the bending block 34 presses the other end of the steel bar. Then, the extension arm 33 is pulled to make the rocker arm 32 rotate downward, driving the steel bar 40 to bend along the bending groove 310, and the bending effect is achieved.

[0037] The opposite sides of the end of the rocker arm 32 close to the bending disc 31 are respectively arrayed with a plurality of adjusting holes 35, and the bending block 34 is spacedly provided with two through holes (not shown in the figure) along its thickness direction, which are used for corresponding to the adjusting holes 35. By connecting butterfly nuts after the adjusting holes 35 and the through holes are connected by bolts, the bending block 34 and the rocker arm 32 can be quickly connected. In actual use, the adjusting holes 35 at different positions can be switched according to needs to adapt to steel bars 40 of different diameters.

[0038] The opposite sides of the end of the rocker arm 32 away from the bending disc 31 are respectively provided with embedding grooves 36, and a plurality of stop blocks 37 are respectively and spacedly connected to the outer sides of the rocker arm 32 corresponding to the embedding grooves 36. The embedding grooves 36 are used for accommodating one end of the extension arm 33.

[0039] Specifically, if Figure 5 and Figure 6 As shown, the telescopic arm 33 includes a handle 331 and telescopic arm bodies 332 connected to opposite sides of one end of the handle 331. The telescopic arm bodies 332 correspond one-to-one with the insertion slots 36, and a stopper 37 is used to prevent the telescopic arm bodies 332 from being disengaged. By fitting the telescopic arm bodies 332 into the insertion slots 36, the telescopic arm 33 can be flexibly adjusted during bending according to the principle of leverage, thereby flexibly adjusting the length of the power arm, thereby achieving a labor-saving effect.

[0040] The above-mentioned construction site steel bar rapid bending equipment has a simple structure and is easy to use. The positioning pressure block 22 and the bending pressure block 34 press the opposite ends of the steel bar 40, and the telescopic arm 33 drives the rocker arm 32 to press down and rotate, so that the steel bar 40 is bent along the bending groove 310 of the bending disk 31 to achieve the bending effect. The shape of the steel bar 40 can be quickly adjusted at the construction site to meet the construction requirements on site.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
