Description

Technical Field

[0001] This utility model relates to the field of steel bar bending technology, and more specifically, to a steel bar bending device for building construction. Background Technology

[0002] In building construction, steel bars are an indispensable raw material. Steel bars have a strong bond with concrete, enabling them to better withstand external forces. During construction, some conditions require bending the steel bars.

[0003] Patent CN222113364U discloses a steel bar bending device for building construction. The device inserts a steel bar between a roller and a circular fixed wheel, restricting it through a first and second annular groove. Simultaneously, the steel bar is placed within a U-shaped frame and clamped and fixed by two clamping plates. A moving component then moves the steel bar for feeding. Once the desired length is reached, a control motor drives a connecting plate and a roller connected below the connecting plate to rotate, bending the steel bar. However, this steel bar bending device can only bend a single steel bar at a time, and cannot bend multiple steel bars simultaneously. Utility Model Content

The rotating wheels and the rotating handle 4 are assembled and connected vertically.

[0046] Specifically, such as Figure 2 and Figure 3 As shown, the rotating wheel includes a bottom rotating wheel 5, several stacked rotating wheels 6, and a top rotating wheel 7;

[0047] The outer wall of the bottom rotating wheel 5 is provided with a second annular groove 51; the center of the bottom rotating wheel 5 is provided with a first connecting hole 52 that runs vertically through it, for bolts to be installed on the workbench 1; the bottom rotating wheel 5 is also provided with a number of second connecting holes 53 that are circumferentially spaced.

[0050] The rotating handle 4 includes a main body 41 and a handle 42 fixedly connected together. The center of the main body 41 has a sixth connecting hole 411 that matches the first connecting hole 52 of the bottom rotating wheel 5, the third connecting hole 62 of the stacked rotating wheel 6, and the fifth connecting hole 72 of the top rotating wheel 7. The main body 41 also has a seventh connecting hole 412 that matches the threaded hole 73 of the top rotating wheel 7. The handle 4 is installed on the top rotating wheel 7 by bolts passing through the seventh connecting hole 412, so that the rotating handle 4 is fixedly connected to the top rotating wheel 7.

[0051] In this embodiment, the rotating wheels are arranged sequentially from bottom to top as follows: bottom rotating wheel 5, a suitable number of stacked rotating wheels 6, and top rotating wheel 7. The first connecting hole 52 of the bottom rotating wheel 5, the third connecting hole 62 of the stacked rotating wheel 6, and the fifth connecting hole 72 of the top rotating wheel 7 overlap and are interconnected. Each stacked rotating wheel 6 is connected to each other by a first locking post 64 and a fourth connecting hole 63 below it. The first locking post 64 of the bottommost stacked rotating wheel 6 is embedded in the second connecting hole 53 corresponding to the bottom rotating wheel 5, and the second locking post 74 of the top rotating wheel 7 is embedded in the fourth connecting hole 63 of the topmost stacked rotating wheel 6. Then, the rotating handle 4 is placed on the top rotating wheel 7, and the seventh connecting hole 412 is aligned with the threaded hole 73 of the top rotating wheel 7. The handle 4 is then installed on the top rotating wheel 7 by bolting through the seventh connecting hole 412, thus fixing the rotating handle 4 to the top rotating wheel 7. Then, long bolts are used to pass through the sixth connecting hole 411 of the rotating handle 4, the first connecting hole 52 of the bottom rotating wheel 5, the third connecting hole 62 of the stacked rotating wheel 6, and the fifth connecting hole 72 of the top rotating wheel 7 and install them in the slide groove 13 of the workbench 1. At this time, the annular groove of each rotating wheel and the first annular groove 31 of each center wheel at the corresponding height contain steel bars. Turning the rotating handle 4 causes the rotating wheel assembly to rotate around the center wheel assembly as the axis, thereby achieving the bending of the steel bars.

[0052] In this embodiment, the workbench 1 has multiple sets of positioning holes 14, and each set of positioning holes 14 is arranged at equal intervals along an arc with the third through hole 12 as the center. The limiting structure 8 can be selectively installed in one set of positioning holes 14. Angle scale lines 15 are also provided next to the positioning holes 14 to help determine the bending angle of the reinforcing bars, and the limiting structure is used for limiting. The limiting structure 8 includes a base plate 81 and a limiting plate 82 perpendicular to the base plate 81. The base plate 81 has fixing holes 811 that are adapted to the positioning holes 14.

[0053] The steel bar bending device for building construction provided in this embodiment can simultaneously bend multiple steel bars by arranging different rotating wheel assemblies, central wheel assemblies, and corresponding clamping structures. The rotating wheel assembly is formed by arranging a bottom rotating wheel 5, a suitable number of stacked rotating wheels 6, a top rotating wheel 7, and a rotating handle 4 in sequence from bottom to top. This assembly is installed in the slide groove 13 of the workbench 1. A long screw passes through the connecting hole at the center of each rotating wheel, and a nut is installed after placing a washer at the bottom of the slide groove 13. The rotating wheel assembly can move along the slide groove 13. The annular groove of each rotating wheel and the first annular groove 31 of each central wheel at the corresponding height accommodate steel bars. The other end of the steel bar is limited by a corresponding clamping structure. Turning the rotating handle 4 causes the rotating wheel assembly to rotate around the central wheel assembly as an axis, thus bending the steel bar. When a bending angle is required for the steel bar, a limiting structure 8 can be installed at a suitable positioning hole 14 to assist in positioning the bending angle of the steel bar.

[0054] The steel bar bending device for building construction provided in this embodiment, such as Figure 4 and Figure 5 As shown, it is also possible to simply install the bottom rotating wheel 5 and one central wheel 3, and simultaneously match a set of clamping structures to achieve bending of a steel bar.

[0055] The steel bar bending device for building construction provided in this embodiment assembles the rotating wheel assembly and the center wheel assembly. The steel bar to be bent is placed in the corresponding annular groove, and the clamping structures clamp the steel bar for easy bending. Then, the rotating handle 4 is held to rotate the rotating wheel assembly around the central axis of the center wheel assembly. The rotating wheel assembly rotates along the slide groove 13 of the worktable 1, at which point the steel bar is bent. When different bending angles are required, the limiting structure 8 is inserted into the corresponding positioning hole 14, and the handle is turned to the limiting plate 82. A protractor can also be used for precise measurement to assist in judging the bending angle. By increasing or decreasing the number of stacked rotating wheels 6, the number of steel bars bent simultaneously can be changed; if only a single steel bar is to be bent, only the bottom rotating wheel 5 and one center wheel 3 are needed.

[0056] The steel bar bending device for building construction provided in this embodiment utilizes a combination of a rotating wheel assembly, a central wheel assembly, and a clamping structure. Its clamping structure, formed by multiple annular grooves and multiple sets of clamping blocks, can simultaneously place steel bars in different spaces and complete the bending of multiple steel bars in one rotation.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
