Description

Technical Field

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

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In housing construction, multi-story masonry houses are one of our main structural types. Earthquake damage shows that under strong earthquakes, the damaged parts of multi-story masonry houses are mainly walls, and the damage to the floor itself is relatively light. We can adopt the method of setting reinforced concrete structural columns to reduce the damage to the walls and improve their earthquake resistance.

[0003] Since the reinforced concrete structural columns are connected to each other, the steel bars inside the structural columns at the turning points need to be bent and then staggered and tied to ensure the strength of the structural column connection parts. Due to the high hardness of the steel bars, a steel bar bending auxiliary device is required when bending the steel bars.

[0004] Application No. CN202321443586.X discloses an auxiliary device for bending steel bars in construction projects, including a mounting frame for carrying various components, the inner wall of the mounting frame is fixedly connected to a steel structure, and the bottom of one side surface of the steel structure is fixedly connected to a support member. This application provides a carrying member, a rotating rod and a lower pressure plate, so that workers can actively fix the device, thereby freeing their hands and avoiding hand injuries.

[0005] In order to improve the aesthetics of the house, loft-style shapes are often cast on the roof. These shapes are short and have many turns, so a single steel bar needs to be bent twice or even multiple times. After a single bending of the steel bar, it is inconvenient to quickly push the steel bar to the next bending position, resulting in low steel bar bending efficiency.

[0006] Therefore, we propose a steel bar bending auxiliary device for construction engineering. Summary of the invention

[0007] The main purpose of the utility model is to provide a steel bar bending auxiliary device for construction projects. After a single bending operation is completed, the steel bar can be quickly pushed so that the next bending operation can be quickly performed. The operation is relatively simple, and the bending efficiency of steel bars that need to be bent multiple times can be greatly improved, which can effectively solve the problems in the background technology.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-4 As shown, a steel bar bending auxiliary device for construction engineering comprises a steel bar bending platform 1 with a U-shaped cross section in a top view, the inner wall of the steel bar bending platform 1 is structured with symmetrically arranged straight grooves 3, and a translation component for driving the horizontal movement of the steel bar is installed between the straight grooves 3, a cushion block 19 and an upper limit block 20 located above the cushion block 19 are fixed to the edge side of the inner wall of the steel bar bending platform 1, and an arc-shaped notch 2 is structured at the end of the steel bar bending platform 1;

[0027] The pad 19 can support the steel bar, and the upper limit block 20 can prevent the steel bar from deflecting downward when pressed from above. Therefore, when the outer side of the steel bar is pressed, the steel bar can be bent along the outer side of the part in contact with the pad 19. Under the action of the arc-shaped notch 2, it is convenient to pass the steel bar into the inner side of the steel bar bending table 1.

[0028] A symmetrically arranged downward pressing bending assembly is installed on the edge side of the surface of the steel bar bending table 1, and a steel bar end downward pressing frame 15 is installed between the bottoms of the downward pressing bending assembly. A limit clamping frame 151 with an inverted V-shaped cross-section is integrally formed on the top of the steel bar end downward pressing frame 15.

[0029] The downward pressure bending assembly can drive the downward pressure frame 15 at the end of the steel bar to move downward from one side of the steel bar bending platform 1, and the steel bar is pressed downward by the downward pressure frame 15 at the end of the steel bar. The bent part of the steel bar can be manually rotated 180 degrees, and the bent part is clamped in the limit clamping frame 151, which is convenient for maintaining the stability of the steel bar when the adjacent bending parts of the steel bar form a Z shape.

[0030] Furthermore, if Figure 3 As shown, the translation assembly includes a linear slide rail 5 installed in a slot 3 on one side, a fitting block 6 is fixedly installed on the side wall of the guide slider 4 of the linear slide rail 5, a steel bar support moving frame 7 that can slide against the inner wall of the steel bar bending table 1 is installed on the side wall of the fitting block 6, a slider 4 slidably set in the slot 3 on the other side is installed on the side of the steel bar support moving frame 7 away from the fitting block 6, the surface of the steel bar support moving frame 7 is constructed with a groove with a semicircular cross-section, and the inner surface of the steel bar support moving frame 7 is higher than the inner surface of the pad 19.

[0031] When the bending position of the steel bar needs to be adjusted, the linear slide rail 5 is started to drive the fitting block 6 to move, so that the fitting block 6 pulls the steel bar support movable frame 7 to move. Since the inner surface of the steel bar support movable frame 7 is higher than the inner surface of the pad 19, when the bending operation is not performed, the steel bar is overlapped between the arc notch 2 and the surface of the steel bar support movable frame 7. Therefore, when the steel bar support movable frame 7 moves horizontally, it can press down on one side of the bending assembly to move the steel bar.

[0032] Furthermore, if Figure 1-2 As shown, the downward pressure bending assembly includes a vertical frame 8 mounted on the surface of the steel bar bending table 1, the side wall of the vertical frame 8 is constructed with a vertical groove, and a screw rod 9 is rotatably arranged in the vertical groove, and a lifting block 10 is rotatably connected to the outer circumference of the screw rod 9 and slidably arranged in the vertical groove, and an extension plate 11 is fixed to the end of the lifting block 10, and a vertical rod 12 is fixed to the bottom of the extension plate 11, and the bottom of the extension plate 11 is fixed to the surface of the downward pressure frame 15 at the end of the steel bar, and a transmission box 16 for transmitting power to the screw rod 9 is installed on the top of the vertical frame 8, and a reduction motor 17 for providing power to the screw rod 9 is installed on the surface of the transmission box 16 at the top of one side of the vertical frame 8, and the transmission boxes 16 are connected through a chain plate and a synchronous chain 18.

[0033] The reduction motor 17 is directly connected to the transmission box 16 below it to provide power output, and the power is transmitted to the screw 9 through the transmission box 16. Under the action of the chain plate and the synchronous chain 18, the screws 9 in the two downward pressure bending components are kept rotating in the same direction at the same time, ensuring that both ends of the downward pressure frame 15 at the end of the steel bar descend at the same speed.

[0034] Furthermore, a positioning groove 13 is constructed on the surface of the steel bar end pressing frame 15, and a pin 14 is penetrated through the side wall of the steel bar end pressing frame 15. A positioning block is fixed to the bottom of the vertical rod 12, and a cylindrical groove is constructed on the side wall of the positioning block.

[0035] With the cooperation of the positioning groove 13 and the positioning block, the vertical rod 12 and the steel bar end pressing frame 15 can be quickly positioned and fitted, and then the pin 14 can be inserted into the cylindrical groove to fix the vertical rod 12 and the steel bar end pressing frame 15. It is convenient to replace the corresponding steel bar end pressing frame 15 according to the diameter and hardness of the bent steel bar.

[0036] It should be noted that the utility model is a steel bar bending auxiliary device for construction engineering. The steel bar end pressing frame 15 that is suitable is selected in advance according to the diameter and hardness of the bent steel bar. The steel bar end pressing frame 15 is lifted up so that the positioning groove 13 fits with the bottom positioning block of the vertical rod 12. The latch 14 passes through the side wall of the steel bar end pressing frame 15 and is inserted into the cylindrical groove of the positioning block. The vertical rod 12 is fixedly connected with the steel bar end pressing frame 15. The steel bar support moving frame 7 is pre-adjusted to one side close to the arc-shaped notch 2. The steel bar is passed through the arc-shaped notch 2, and the other end is passed between the cushion block 19 and the upper limit block 20. The reduction motor 17 is started to drive the screw 9 to rotate through the transmission box 16. The lifting block 10 drives the steel bar end pressing frame 15 to move downward through the extension plate 11 and the vertical rod 12 to extrude and bend the exposed part of the steel bar. After bending to a suitable angle, the reduction motor 17 is driven in the reverse direction to reset the steel bar end pressing frame 15. The linear slide rail 5 drives the steel bar supporting mobile frame 7 to move horizontally to change the bending part of the steel bar. If the adjacent bending parts are in a Z shape, the bent part of the steel bar can be rotated to clamp the bent part in the limit clamping frame 151 to prevent the Z-shaped bending part from being unable to be in the same plane.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
