Description

Technical Field

[0001] This utility model belongs to the technical field of diameter adjustment devices, specifically, it relates to a circular hoop diameter adjustment device for building construction. Background Technology

[0002] In modern building construction, steel bars are an important building material, and the quality of their processing and forming directly affects the stability and safety of the building structure. Forming steel bars into circular components of a specific diameter is one of the key steps in constructing bridges, tunnels, buildings, and other architectural structures.

[0003] Currently, common methods for rounding rebar mainly include manual bending and processing with traditional mechanical equipment. Manual bending of rebar relies on worker experience and physical strength, which is not only inefficient but also makes it difficult to guarantee the consistency of the bending angle and diameter, failing to meet the precision requirements of large-scale construction. While traditional mechanical equipment improves processing efficiency to some extent, it is often limited in function, only capable of processing rebar of specific specifications and diameters. When processing rebar of different diameters, it usually requires changing complex molds or adjusting equipment parameters, making the operation cumbersome and time-consuming, increasing construction and time costs. Secondly, there is a simple rounding device consisting of three wooden blocks of different lengths (block 1, block 4, and block 5) stacked together. The stacked blocks are distributed circumferentially on a table to form a circle (see reference). Figure 5 However, this device also has the problem that the diameter of the hoop is not easy to adjust. To address this, a hoop diameter adjustment device for building construction is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a circular hoop diameter adjustment device for building construction that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is: a circular hoop diameter adjustment device for building construction, comprising: multiple lead screws arranged circumferentially, each of the multiple lead screws being threadedly connected to a slider; a synchronous drive assembly for synchronously driving the multiple lead screws to rotate synchronously; and a limit baffle installed on the slider, with an operating gap left between the limit baffle and the front end of the slider.

[0006] Preferably, the synchronous drive assembly includes a meshing bevel gear disk and a bevel gear.

[0007] Preferably, the device further includes a support table, the bevel gear disk is rotatably connected to the support table, a motor is installed at the bottom of the support table, the bevel gear disk is fixedly connected to the output end of the motor, and a controller is installed on the support table to control the motor to start or stop.

[0008] Preferably, a slide rail is installed on the bearing table at the position corresponding to the lead screw, and a slide block is installed at the bottom of the slider, the slide block being slidably connected to the slide rail.

[0009] Preferably, the two ends of the lead screw are rotatably connected to connecting seats, and the connecting seats are mounted on the bearing table.

[0010] Furthermore, a groove is provided at the front end of the slider.

[0011] Furthermore, the limiting baffle is located on two adjacent sliders, and a docking working area is formed between the two limiting baffles.

[0012] Furthermore, the limiting baffle is located on each slider.

[0013] Furthermore, a ruler is installed on the support table.

[0014] Furthermore, a protective cover is installed on the support table to cover the bevel gear disc and bevel gear.

[0015] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This utility model uses a motor to drive a bevel gear disk, bevel gears, and other synchronous drive components to drive multiple lead screws to rotate synchronously, so that multiple sliders mounted on the lead screws can synchronously change their position relative to the center of the bevel gear disk, thereby precisely adjusting the diameter required for the rebar to bend. A scale set on the support table allows users to easily adjust to the specified size; the groove at the front end of the slider can limit the rebar and prevent it from slipping out. Furthermore, by adding a pad of the same thickness in the groove, the depth of the groove can be flexibly adjusted, facilitating the placement and removal of the rebar. An operating gap is left between the limiting baffle and the front end of the slider, making it easy to insert one end of the rebar, and then manually rotate it around the support table to complete the bending and rounding of the rebar, making the operation simple. In addition, the sliding seat at the bottom of the slider is slidably connected to the slide rail on the support table, making the slider slide more smoothly under the drive of the lead screw. The protective cover installed on the support table can cover the bevel gear disk and bevel gears, preventing operators from contacting dangerous parts. In terms of the setting of the limiting baffle, the limiting baffle is located on two adjacent sliders. The docking working area formed between the two limiting baffles facilitates the limiting of both ends of the steel bar, making it convenient to weld the two ends of the steel bar in this area. In another embodiment, the limiting baffle is located on each slider, which can prevent the steel bar from slipping off the slider and being thrown out and injuring people when bending. It ensures operational safety from different angles and reduces construction risks.

[0016] Therefore, compared with existing technologies, this device can flexibly and conveniently adjust the diameter of the circle to be formed by the reinforcing bar.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Example 1: Refer to Figures 1-4 A circular hoop diameter adjustment device for building construction includes: multiple screw rods 14 arranged circumferentially, each screw rod 14 being threadedly connected to a slider 16; a synchronous drive assembly for synchronously driving the multiple screw rods 14 to rotate synchronously; and a limit baffle 19 installed on the slider 16, with an operating gap between the limit baffle 19 and the front end of the slider 16.

[0027] The synchronous drive assembly includes a meshing bevel disk 11 and a bevel gear 12.

[0028] It also includes a support table 1, a bevel gear disk 11 rotatably connected to the support table 1, a motor installed at the bottom of the support table 1, the bevel gear disk 11 being fixedly connected to the output end of the motor, and a controller 22 installed on the support table 1 to control the motor to start or stop.

[0029] A slide rail 15 is installed on the bearing table 1 at the position corresponding to the lead screw 14. A slide seat 18 is installed at the bottom of the slider 16. The slide seat 18 is slidably connected to the slide rail 15. The setting of the slide rail 15 makes the slider 16 slide more smoothly under the drive of the lead screw 14.

[0030] The two ends of the lead screw 14 are rotatably connected to the connecting seats 13, which are installed on the bearing table 1 to improve the stability of the rotation of the lead screw 14 and prevent vibration.

[0031] A ruler 21 is installed on the support table 1.

[0032] A protective cover is installed on the support table 1 to cover the bevel gear 11 and bevel gear 12, thereby improving the safety of use.

[0033] In use, the motor is started by the controller 22, i.e. the control switch. The motor is a geared motor, which slowly drives the bevel gear disk 11 to rotate. When the bevel gear disk 11 rotates, it drives multiple lead screws 14 to rotate synchronously through the bevel gear 12. When rotating, it drives the slider 16 to move on the lead screw 14, thereby changing the diameter of the multiple circumferential sliders 16 relative to the steel bar ring.

[0034] The scale 21 allows for easy adjustment to a specified size;

[0035] In addition, the controller 22 can be located near the scale 21, so that the motor can be turned off in time after the desired size is adjusted;

[0036] Then, one end of the rebar is inserted into the operating gap formed between the limiting baffle 19 and the slider 16. The rebar is then manually held and rotated around the bearing table 1 to bend it, so that the other end of the rebar is close to the end of the rebar located between the limiting baffle 19 and the slider 16, thus completing the rebar circle.

[0037] After the circle is formed, the two ends can be welded together by electric welding.

[0038] Therefore, this device can use a motor to drive multiple sliders 16 to synchronously change their position relative to the center of the bevel gear disk 11, thereby facilitating the adjustment of the diameter required for the steel bar ring.

[0039] The slider 16 has a groove 17 at its front end. The groove 17 can limit the rebar and prevent the rebar from slipping off the slider 16. When the rebar is rounded but not welded, it can be directly removed. When the rebar is rounded and welded, the slider 16 can be moved away from the rebar by reversing the drive screw 14, and then removed.

[0040] Furthermore, the depth of the groove 17 can be set shallow, which makes it easier to remove the reinforcing bar without driving the lead screw 14 to reverse.

[0041] When it is necessary to change the depth of the groove 17, a pad of the same thickness can be added to the groove 17 to facilitate changing the depth of the groove 17.

[0042] Example 2: Refer to Figure 4 A circular hoop diameter adjustment device for building construction is basically the same as that in Embodiment 1, but with the following additional feature: a limiting baffle 19 is located on two adjacent sliders 16, and a docking working area 2 is formed between the two limiting baffles 19.

[0043] Setting only two limiting baffles 19 can facilitate limiting the two ends of the reinforcing bar and make the two ends of the reinforcing bar located in the butt welding area 2 for easy welding.

[0044] Example 3: A circular hoop diameter adjustment device for building construction, which is basically the same as Example 2, but further: the limiting baffle 19 is located on each slider 16.

[0045] This design facilitates the removal of the reinforcing bar from the slider 16 when it bends, preventing the reinforcing bar from being thrown out and causing injury, thereby improving safety during use.

[0046] This invention utilizes a motor-driven synchronous drive assembly, including a bevel gear disc 11 and a bevel gear 12, to rotate multiple lead screws 14 synchronously. This allows multiple sliders 16 mounted on the lead screws 14 to simultaneously change their position relative to the center of the bevel gear disc 11, thereby precisely adjusting the required diameter for bending the rebar. A scale 21 on the support table 1 facilitates user adjustment to the specified dimensions. A groove 17 at the front end of the slider 16 limits the rebar's position, preventing slippage. Furthermore, by adding a pad of the same thickness within the groove 17, its depth can be flexibly adjusted, facilitating the placement and removal of the rebar. An operating gap is provided between the limiting baffle 19 and the front end of the slider 16, allowing one end of the rebar to be inserted. Manual rotation around the support table 1 then completes the bending and bending of the rebar, simplifying the operation. Additionally, a sliding base 18 at the bottom of the slider 16 is slidably connected to a slide rail 15 on the support table 1, ensuring smoother sliding of the slider 16 under the drive of the lead screws 14. The protective cover installed on the support table 1 can cover the bevel gear 11 and bevel gear 12, preventing operators from contacting dangerous parts. Regarding the setting of the limiting baffle 19, the limiting baffle 19 is located on two adjacent sliders 16, and the docking working area 2 formed between the two limiting baffles 19 facilitates the limiting of both ends of the reinforcing bar, making it convenient for welding the two ends of the reinforcing bar in this area; in another embodiment, the limiting baffle 19 is located on each slider 16, which can prevent the reinforcing bar from slipping off the slider 16 and throwing out, causing injury, thus ensuring operational safety from different angles and reducing construction risks.
