Description

Technical Field

[0001] This application relates to the field of rebar positioning technology, and in particular to a positioning frame for inserting rebar into a foundation column. Background Technology

[0002] In building construction, the positioning of reinforcing bars in foundation columns is a crucial step. Traditional methods for positioning reinforcing bars typically rely on manual measurement and temporary fixing, resulting in low efficiency and poor accuracy. With increasing structural complexity and stringent quality requirements, high-precision, high-efficiency reinforcing bar positioning technology has become an urgent need in the industry.

[0003] The most common method for positioning rebar is manual string line positioning, which involves measuring and laying out lines and then manually binding and fixing them. Although this method is low in cost, the positioning accuracy is greatly affected by human factors and the efficiency is low. Therefore, an improvement has been made to a positioning frame for inserting rebar into foundation columns. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a positioning frame for the reinforcing bars of the foundation column, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a positioning frame for the reinforcing bars of a foundation column, comprising a horizontal reference frame, wherein a positioning frame is fixedly installed on the top of the horizontal reference frame via telescopic support legs, the positioning frame having a plurality of sliding grooves inside, and a sliding rod fixedly connected inside each of the sliding grooves, wherein two radial positioning members are slidably sleeved on the outer wall of the sliding rod, and the two radial positioning members are fixedly connected to each other by locking bolts, wherein a tension spring is sleeved on the outer wall of the sliding rod outside the radial positioning members, and the radial positioning members are fixedly connected to the inner wall of the sliding grooves via the tension springs.

[0006] By adopting the above technical solution, the horizontal reference frame serves as the basic support, providing a stable reference plane for the entire positioning frame. The positioning frame is connected to the horizontal reference frame through telescopic support legs, which can be adjusted in height and kept horizontal, ensuring the positioning accuracy of the rib in the vertical direction. The sliding groove and sliding rod inside the positioning frame form a linear guide rail structure, allowing the radial positioning component to slide freely radially on the sliding rod, moving closer to the rib from both sides. After the two radial positioning components slide close to the rib, they can be fixedly connected by locking bolts, thereby achieving a firm fixation of ribs of different sizes within a certain range. A tension spring is provided on the outer side of each of the two radial positioning components, which can apply the same elastic force to the radial positioning component, keeping the radial positioning component stably in the center position of the sliding groove, thereby accurately limiting the position of the rib.

[0007] As a preferred technical solution of this application, bolt connection holes are provided at the four corners of the upper surface of the horizontal reference frame, and a connecting flange is fixedly connected to the bottom of the telescopic support leg. The connecting flange is threadedly connected to the bolt connection hole by connecting bolts.

[0008] By adopting the above technical solution, the telescopic support leg is fixedly installed on the top of the horizontal reference frame through the cooperation between the connecting flange, connecting bolts and bolt connection holes.

[0009] As a preferred technical solution of this application, the radial positioning member has a circular hole inside for the sliding rod to pass through. The inner diameter of the circular hole is adapted to the outer diameter of the sliding rod, and the outer dimensions of the radial positioning member are adapted to the internal space dimensions of the sliding groove.

[0010] By adopting the above technical solution, the inner diameter of the inner hole of the radial positioning component is matched with the outer diameter of the sliding rod, forming a tight and smooth sliding fit. The outer dimensions of the radial positioning component are matched with the inner space dimensions of the sliding groove, so that the radial positioning component is always within the effective constraint range of the sliding groove during the sliding process.

[0011] As a preferred technical solution of this application, several radial positioning members are symmetrically distributed in pairs inside the sliding groove, and an arc-shaped groove is provided on the opposite side of any two radial positioning members in any pair.

[0012] By adopting the above technical solution, the radial positioning components are symmetrically distributed in pairs. When fixed by locking bolts, they can apply a balanced clamping force to the reinforcing bars from both sides, avoiding the reinforcing bars from tilting or shifting due to uneven force. The arc-shaped grooves set on the opposite side of the two radial positioning components match the cross-section of the circular reinforcing bars, increasing the contact area between the radial positioning components and the reinforcing bars.

[0013] As a preferred technical solution of this application, the telescopic support leg includes a vertical pole, an adjusting sleeve is slidably sleeved on the outer wall of the vertical pole, the top of the adjusting sleeve is fixedly connected to the bottom of the positioning frame, a finding platform is fixedly connected to the outer wall of the adjusting sleeve near the bottom, a tightening bolt is inserted into the internal thread of the finding platform, and the front end of the tightening bolt abuts against the outer wall of the vertical pole.

[0014] By adopting the above technical solution, the sliding sleeve design of the vertical pole and the adjusting sleeve gives the telescopic support leg a flexible height adjustment capability, and after the top bolt is tightened against the vertical pole, the adjusting sleeve can be firmly locked.

[0015] As a preferred technical solution of this application, the number of vertical poles and adjusting sleeves are both four and correspond one-to-one, and the side wall of the vertical pole is provided with a scale.

[0016] By adopting the above technical solution, the four vertical poles and the adjusting sleeves are distributed in a one-to-one correspondence to form a stable quadrilateral support structure. The scale set on the side wall of each vertical pole provides a quantitative reference for height adjustment, accurately controls the lifting distance of the adjusting sleeve, and ensures that the height of the four telescopic support legs is consistent.

[0017] As a preferred technical solution of this application, the horizontal reference frame is made of square steel tube by welding, and an installation block is fixedly welded to the inner wall of the horizontal reference frame. The installation block has an installation hole inside, and an installation bolt is threaded into the installation block through the installation hole.

[0018] By adopting the above technical solution, the horizontal reference frame made by welding square steel pipes provides a solid foundation support for the entire positioning frame due to its high rigidity and compressive strength. The combination design of mounting blocks, mounting holes and mounting bolts enables the horizontal reference frame to be quickly and firmly fixed on the construction plane. During construction, the horizontal reference frame can be fixed on the foundation template simply by passing the mounting bolts through the mounting holes and tightening them.

[0019] In summary, the beneficial effects of this application are as follows: 1. In this application, the horizontal reference frame serves as the basic support, providing a stable reference plane for the entire positioning frame. The positioning frame is connected to the horizontal reference frame through telescopic support legs, which can be adjusted in height and kept horizontal, ensuring the positioning accuracy of the insert in the vertical direction. The sliding groove and sliding rod inside the positioning frame form a linear guide rail structure, allowing the radial positioning component to slide freely along the sliding rod and approach the insert from both sides.

The scale set on the side wall of each vertical pole provides a quantitative reference for height adjustment, accurately controls the lifting distance of the adjusting sleeve, and ensures that the height of the four telescopic support legs is consistent.

[0023] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a positioning frame for the reinforcing bars of a foundation column, including a horizontal reference frame 1. A positioning frame 6 is fixedly installed on the top of the horizontal reference frame 1 via telescopic support legs 5. The positioning frame 6 has several sliding grooves 7 inside, and sliding rods 8 are fixedly connected inside each of the sliding grooves 7. Two radial positioning elements 9 are slidably sleeved on the outer wall of the sliding rod 8, and the two radial positioning elements 9 are fixedly connected by locking bolts 10. A tension spring 11 is sleeved on the outer wall of the sliding rod 8 outside the radial positioning elements 9. The radial positioning elements 9 are fixedly connected to the inner wall of the sliding grooves 7 via the tension springs 11. In use, the horizontal reference frame 1 serves as a basic support, providing a stable reference plane for the entire positioning frame. The positioning frame 6... The telescopic support leg 5 is connected to the horizontal reference frame 1, which can adjust the height and keep it horizontal, ensuring the positioning accuracy of the insert in the vertical direction. The sliding groove 7 and sliding rod 8 inside the positioning frame 6 form a linear guide structure, which allows the radial positioning member 9 to slide freely in the radial direction on the sliding rod 8 and move closer to the insert from both sides. After the two radial positioning members 9 slide close to the insert, they can be fixedly connected by locking bolts 10, thereby achieving a firm fixation of inserts of different sizes within a certain range. A tension spring 11 is provided on the outside of each of the two radial positioning members 9. They can apply the same elastic force to the radial positioning members 9, so that the radial positioning members 9 are stably held in the center position of the sliding groove 7, thereby accurately limiting the position of the insert.

[0025] In this embodiment, as Figure 2As shown, bolt connection holes 2 are provided at the four corners of the upper surface of the horizontal reference frame 1. The bottom of the telescopic support leg 5 is fixedly connected to the connecting flange 3. The connecting flange 3 is threadedly connected to the bolt connection hole 2 by the connecting bolt 4. In use, the telescopic support leg 5 is fixedly installed on the top of the horizontal reference frame 1 by the cooperation between the connecting flange 3, the connecting bolt 4 and the bolt connection hole 2.

[0026] In this embodiment, as Figure 3 As shown, the radial positioning component 9 has a circular hole through which the sliding rod 8 passes. The inner diameter of the circular hole matches the outer diameter of the sliding rod 8. The outer dimensions of the radial positioning component 9 match the inner space dimensions of the sliding groove 7. In use, the inner diameter of the circular hole inside the radial positioning component 9 matches the outer diameter of the sliding rod 8, forming a tight and smooth sliding fit. The outer dimensions of the radial positioning component 9 match the inner space dimensions of the sliding groove 7, so that the radial positioning component 9 is always within the effective constraint range of the sliding groove 7 during the sliding process.

[0027] In this embodiment, as Figure 3 As shown, several radial positioning elements 9 are symmetrically distributed in pairs inside the sliding groove 7, and an arc-shaped groove is provided on the opposite side of any two radial positioning elements 9 in any pair. In use, the radial positioning elements 9 are symmetrically distributed in pairs. When fixed by locking bolts 10, they can apply a balanced clamping force to the insert bar from both sides, preventing the insert bar from tilting or shifting due to uneven force. The arc-shaped groove provided on the opposite side of the two radial positioning elements 9 matches the cross-section of the circular steel bar, increasing the contact area between the radial positioning elements 9 and the insert bar.

[0028] In this embodiment, as Figure 4 As shown, the telescopic support leg 5 includes a vertical pole 51. An adjusting sleeve 52 is slidably sleeved on the outer wall of the vertical pole 51. The top of the adjusting sleeve 52 is fixedly connected to the bottom of the positioning frame 6. A platform 53 is fixedly connected to the outer wall of the adjusting sleeve 52 near the bottom. A tightening bolt 54 is inserted into the internal thread of the platform 53. The front end of the tightening bolt 54 abuts against the outer wall of the vertical pole 51. In use, the sliding sleeve design of the vertical pole 51 and the adjusting sleeve 52 gives the telescopic support leg 5 a flexible height adjustment capability. After the tightening bolt 54 abuts against the vertical pole 51, it can firmly lock the adjusting sleeve 52.

[0029] In this embodiment, as Figure 1 and 4As shown, there are four vertical poles 51 and four adjusting sleeves 52, each corresponding to the other. The side wall of the vertical pole 51 is provided with a scale 55. In use, the four vertical poles 51 and the adjusting sleeves 52 are distributed in a one-to-one correspondence to form a stable quadrilateral support structure. The scale 55 on the side wall of each vertical pole 51 provides a quantitative reference for height adjustment, accurately controls the lifting distance of the adjusting sleeves 52, and ensures that the four telescopic support legs 5 are at the same height.

[0030] In this embodiment, as Figure 2 As shown, the horizontal reference frame 1 is made of square steel tubes welded together. The inner wall of the horizontal reference frame 1 is fixedly welded with mounting blocks 12. The mounting blocks 12 have mounting holes inside. Mounting bolts are threaded into the mounting blocks 12 through the mounting holes. In use, the horizontal reference frame 1, made of square steel tubes welded together, provides a solid foundation support for the entire positioning frame due to its high rigidity and compressive strength. The combination design of the mounting blocks 12, mounting holes and mounting bolts allows the horizontal reference frame 1 to be quickly and firmly fixed on the construction plane. During construction, the horizontal reference frame 1 can be fixed on the foundation template simply by passing the mounting bolts through the mounting holes and tightening them.

[0031] The working principle of this application is as follows: When using the positioning frame for the reinforcing bar of the foundation column of this application, the horizontal reference frame 1 is calibrated by measuring tools such as a level. The mounting bolts are passed through the mounting holes and tightened to fix the horizontal reference frame 1 on the foundation template. According to the design height of the reinforcing bar, referring to the scale 55 on the side wall of the vertical pole 51, the sliding adjustment sleeve 52 drives the positioning frame 6 to rise and fall. At the same time, the level of the positioning frame 6 is monitored by a level. After the adjustment is completed, the top bolt 54 on the platform 53 is tightened to lock the adjustment sleeve 52 with the vertical pole 51, ensuring that the positioning frame 6 is at the same height and horizontal. According to the diameter of the reinforcing bar, the locking bolt 10 is loosened, and the two radial positioning pieces 9 in the same sliding groove 7 are pushed to slide along the sliding rod 8 so that the arc groove distance between the two is slightly larger than the diameter of the reinforcing bar, which facilitates the insertion of the reinforcing bar. After the reinforcing bar is inserted, the external force is released, the tension spring 11 contracts and drives the radial positioning pieces 9 to fit the reinforcing bar from both sides for initial positioning. The locking bolt 10 between the two radial positioning pieces 9 is tightened to achieve a firm fixation of the reinforcing bar.
