Description

Technical Field

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

[0002] In order to enhance the tensile strength and durability of concrete, steel bars are needed during the construction process to withstand the stress of concrete under tension, thereby improving the strength and stability of the overall building structure. At the same time, the design of building structures often requires steel bars of specific shapes and sizes, so it is often necessary to bend the steel bars into specific angles or curved shapes.

[0003] For steel bars with smaller diameters, a manual steel bar bending device can be used to bend the steel bars. When in use, construction workers need to place the steel bars on the manual steel bar bending device according to the design requirements, and then manually pull the handle on the manual steel bar bending device to use the lever principle to bend the steel bars to the desired angle. However, the existing manual steel bar bending device lacks a limiting effect on the steel bars during the bending process. The steel bars are prone to slipping off the manual steel bar bending device or even ejected during the stress process, accidentally injuring surrounding construction workers. At the same time, the existing manual steel bar bending device generally does not have an adjustment function and can only bend steel bars of one thickness and specification, which is less practical. To this end, we propose a steel bar bending device for construction. Utility Model Content

[0024] See also Figure 2 The fixing assembly shown in the figure includes a screw 19 and a plurality of screw holes 14. The screw 19 penetrates through the inner wall of the collar 8 and is screwed therein. A plurality of screw holes 14 are linearly arranged in an array on the top of the outer wall of the sleeve 7.

[0025] See also Figure 1 , Figure 5 and Figure 6 In the figure, the holding member includes a handle 13, and the handle 13 is fixedly connected to the front end of the connecting rod 10.

[0026] Working principle: First, turn the handle 13 upward, the handle 13 will drive the connecting rod 10 to rotate, and the connecting rod 10 will drive the connecting plate 9 to rotate on the U-shaped plate 2 until the connecting rod 10 rotates 90 degrees, and the steel bar to be bent is placed between the base 1 and the sleeve 7, and the steel bar is located between the ring 8 on the sleeve 7 and the slide plate 3, as shown in FIG. Figure 5 As shown, the handle 13 can be pulled downward, and the connecting rod 10 can drive the connecting column 11 located below to rotate, and the sleeve 12 on the connecting column 11 can be rotated to bend the steel bar. The steel bar will slide between the base 1 and the sleeve 1 7 during the bending process, and the sleeve 1 7 will rotate on the connecting column 1 6, and the sleeve 12 located below will rotate on the outer wall of the connecting column 11, thereby reducing the friction during the bending process of the steel bar and saving more effort. If the bent steel bar needs to be further bent, the steel bar can be bent according to the same operation as shown in the figure. Figure 6 After being placed in the state shown, the handle 13 can be pulled downwards to further bend the already bent steel bar, which is easy to operate.

[0027] Due to the limiting effect of the sleeve 7, the sleeve 7 can prevent the steel bar from slipping off between the base 1 and the sleeve 7 during the bending process. When a steel bar with a larger diameter needs to be bent, the two screws 4 can be rotated outward in sequence with the help of a screwdriver. The two screws 4 will rotate outward in the inner wall of the slide plate 3, and the two screws 4 will also rotate outward in a screw hole 18 on the corresponding U-shaped plate 2, until the two screws 4 are completely rotated away from the corresponding screw hole 18, and then the slide plate 3 is moved upward, and the slide plate 3 will drive the connecting column 6 and the sleeve 7 on the connecting column 6 Move upward (during this process, the slide plate 3 will slide upward on the side wall of the U-shaped plate 2, and the T-shaped block 15 on the slide plate 3 will slide upward in the T-shaped slot 5 on the U-shaped plate 2) until the sleeve 7 moves to the required height, and then turn the two screws 4 inward in sequence, both of which will turn inward in the inner wall of the slide plate 3, and both of which will be inserted into and tightened in the other screw hole 18 on the corresponding set of screw holes 18, so that the slide plate 3 can be kept in a fixed state again after moving upward, and the height of the sleeve 7 can be kept in a fixed state again after moving upward.

[0028] Then, screw 2 19 is turned upward, and screw 2 19 will rotate upward in the inner wall of the collar 8, and screw 2 19 will also rotate upward in a corresponding screw hole 2 14 on the sleeve 1 7, until screw 2 19 is completely turned away from the screw hole 2 14, and then the collar 8 is moved in the direction away from the slide plate 3, and the collar 8 will slide on the outer wall of the sleeve 1 7 in the direction away from the slide plate 3 (in this process, the slider 16 on the collar 8 will slide in the slide groove 17 on the sleeve 1 7 in the direction away from the slide plate 3), until the collar 8 moves to the required position, and then screw 2 19 is turned downward, and screw 2 19 will rotate downward in the inner wall of the collar 8, and screw 2 19 will be inserted into and tightened in another screw hole 2 14 on the sleeve 1 7, so that the collar 8 can be kept fixed again after the movement, and then the steel bars with larger diameter can be bent according to the same method described previously.

[0029] It should be noted that the device saves effort in bending steel bars and can increase the stability of the steel bars, preventing the steel bars from slipping or even ejecting during the bending process and accidentally injuring surrounding construction workers. The device has high safety and can bend steel bars of different thicknesses and models, and has good practicality.
