Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, and in particular to a tool for drilling holes in beam side formwork. Background Technology

[0002] Before pouring concrete beams, formwork needs to be erected. In existing projects, tie bolts are often used to connect and stabilize the formwork on both sides of the concrete beam. The tie bolts need to pass through the formwork on both sides of the beam. Before the tie bolts pass through the formwork on both sides of the concrete beam, holes need to be drilled in the formwork on both sides of the concrete beam in advance.

[0003] In traditional construction sites, the common method for drilling holes in the formwork on both sides of concrete beams is for workers to hold electric drills, squat down, and drill holes one by one at the corresponding positions in the formwork. This increases the labor intensity of the workers, resulting in low work efficiency, high labor input, and increased construction costs. Utility Model Content

[0021] Example 1 See Figures 1 to 4 This utility model provides a tool for drilling holes in beam side formwork, including a central tube 1, with a base frame 2 fixedly installed at the lower end of the central tube 1; Two sets of drilling mechanisms 3 are provided at the lower end of the central tube 1, and the two sets of drilling mechanisms 3 are arranged symmetrically. Each set of drilling mechanisms 3 includes two support rods 4 rotatably mounted on the central tube 1. The movable ends of the two support rods 4 are rotatably mounted on upright rods 5, and the two ends of the upright rods 5 are rotatably connected to the support rods 4 respectively. A sleeve 6 is slidably installed in the middle of the central tube 1. Two control rods 7 are rotatably installed on the side wall of the sleeve 6, and each control rod 7 is rotatably connected to an adjacent support rod 4. Each pole 5 is equipped with a set of drilling units 8, and the two drilling units 8 are arranged symmetrically.

[0022] The base frame 2 is placed on the bottom formwork of the beam. Through the sliding sleeve 6, the sleeve 6 drives the two control rods 7 rotatably connected on the side wall to move synchronously. The control rods 7 push the support rod 4, which in turn drives the upright 5 to fit tightly against the side formwork of the beam. Through the drilling unit 8, the side formwork of the beam is drilled synchronously. After drilling is completed, slide the sleeve 6 in the reverse direction, and drive the upright 5 and drilling unit 8 to reset via the control rod 7 and support rod 4. Then remove the tool.

[0023] The drilling unit 8 includes a mounting base 9 fixedly mounted on the upright 5, a slide rod 10 fixedly mounted on the mounting base 9, a guide rod 11 fixedly mounted on one side of the slide rod 10, a sliding seat 12 slidably mounted on the slide rod 10, the sliding seat 12 being slidably connected to the guide rod 11, a hand drill 13 fixedly mounted on the sliding seat 12, and a drill bit mounted on the hand drill 13. A sliding sleeve 14 is slidably installed at the upper end of the central tube 1. The sliding sleeve 14 is provided with two rotatable connecting rods 15, each of which is rotatably connected to one of the sliding seats 12.

[0024] A tension spring is fitted on the guide rod 11, with one end of the tension spring fixedly connected to the sliding seat 12 and the other end fixedly connected to the guide rod 11; When the upright 5 is close to the beam side formwork, the user moves the sliding sleeve 14 downwards, so that the sliding sleeve 14 pushes the two sliding seats 12 to move in opposite directions under the action of the connecting rod 15. At this time, the electric drill 13 is used to drill holes in the beam side formwork until the formwork is penetrated. The upright 5 has a long slot, and a bolt is installed at each end of the mounting base 9. The bolt passes through the long slot, and the mounting base 9 is fastened to the upright 5 by the bolt. The height of the mounting base 9 can be adjusted via the long slot, making it suitable for drilling holes in beam side formwork of various height specifications, thus significantly improving its versatility.

[0025] A baffle is fixedly installed in the middle of the mounting base 9, and a spring 16 is fixedly installed on the baffle. One end of the spring 16 is fixed to the baffle, and the other end is fixedly connected to the sleeve 6.

[0026] After drilling is completed, the pre-tightened spring 16 will release its elastic potential energy, generating a reverse thrust on the sleeve 6, which helps the sleeve 6 slide back along the central tube 1. The support rod 4 and the upright rod 5 can be driven back to their original positions without manual force, reducing the intensity of operation and making the reset process smoother and more efficient.

[0027] A slot is opened in the middle of the central tube 1, and a slide plate is fixedly installed on the sleeve 6. The slide plate slides in the slot, and a vertical rod 17 is fixedly installed on the slide plate. The upper end of the vertical rod 17 extends to the outside of the central tube 1 and a handle 18 is fixedly installed thereon.

[0028] Hold the handle 18 at the upper end of the vertical rod 17 and push the sleeve 6 to move along the central tube 1. The sleeve 6 drives the control rod 7 to push the support rod 4. The support rod 4 drives the vertical rod 5 to move closer to the beam side formwork. At the same time, the sleeve 6 compresses the spring 16 until the vertical rod 5 is in close contact with the surface of the beam side formwork. The spring 16 is in a pre-tight state, keeping the handle 18 in a fixed position.

[0029] The handle 18 provides a clear point of force application for the sliding of the sleeve 6. Compared with directly pushing the sleeve 6, the handle 18 is ergonomic, making it easier for the operator to control the force and greatly reducing the intensity of operation during the adjustment process. Moreover, the handle 18 drives the slide plate and the sleeve 6 to move together, making the adjustment action more continuous and smooth.

[0030] A handle 19 is also fixedly installed on the sliding sleeve 14.

[0031] The handle 19 provides a clear force application component for controlling the drill bit feed, making it easier for the operator to use and making the operation process smoother and more consistent.

[0032] A pad 20 is fixedly installed at each end of the upright 5.

[0033] When using this utility model, the base frame 2 is placed on the bottom template of the beam. Through the sliding sleeve 6, the sleeve 6 drives the two control rods 7 rotatably connected on the side wall to move synchronously. The control rods 7 push the support rod 4, which in turn drives the upright 5 to fit tightly against the side template of the beam. Through the drilling unit 8, the side template of the beam is drilled synchronously. After drilling is completed, slide the sleeve 6 in the reverse direction, and drive the upright 5 and drilling unit 8 to reset via the control rod 7 and support rod 4. Then remove the tool.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
