Description

Technical Field

[0001] This utility model relates to the field of building construction technology; specifically, this utility model relates to a precise positioning device for the main reinforcement bars of a frame column. Background Technology

[0002] Frame columns have a wide range of applications, but due to their large weight, frame column construction usually adopts fixed clamps or point-laying construction.

[0003] The existing positioning methods are: 1) using the original design stirrups for positioning; 2) using welded positioning clips of different sizes of steel bars. Using the original design stirrups for positioning: This method requires wire binding for both the inner and outer stirrups, which is prone to loosening and falling off, has low accuracy, and is slow to construct. Using welded positioning clips of different sizes of steel bars for positioning: This method requires welding different specifications and sizes of steel bar positioning clips according to different column designs, resulting in a large welding workload, inaccuracy deviations, and unsuitability for mass production in factories.

[0004] For example, patent application number 202323193894.4 discloses a novel frame column clamp, belonging to the field of frame column technology in subway construction. It includes a frame, angle iron, clamping strip, and reinforcing bars. The frame is composed of several angle irons connected end to end, so the shape of the frame can be adjusted according to the specific construction design, such as a quadrilateral or other polygonal shape, to adapt to different frame columns. The angle iron is fixed to several parallel reinforcing bars by mechanical clamping. That is, several first slots are provided on the angle iron, and the reinforcing bars are embedded in the first slots. Correspondingly, clamping strips are also slidably provided on the angle iron, and the clamping strips are provided with several second slots. The first slots and the second slots correspond one-to-one. When it is necessary to fix the angle iron to the reinforcing bars, by sliding and fixing the clamping strips, the first slots and the second slots are misaligned, which can achieve the technical effect of clamping and fixing the reinforcing bars with the frame.

[0005] However, in the above solution, the frame does not need to be disassembled in actual use. When pouring concrete, the frame remains inside the concrete. This method is costly, and the frame cannot be reused. If the frame needs to be disassembled, it can only be pulled out along the direction of the reinforcing bar. This disassembly method is not convenient. At the same time, if the reinforcing bar is deformed, the frame may get stuck on the reinforcing bar and cannot be easily removed from the reinforcing bar.

[0023] like Figure 1-5 As shown, a typical embodiment of this utility model provides a precise positioning device for the main reinforcement bars of a frame column, including: a positioning component 1 and a fixing component 2; the positioning component 1 includes a first positioning component 1.1 and a second positioning component 1.2, both the first positioning component 1.1 and the second positioning component 1.2 include a first positioning clamp 3 and a second positioning clamp 4, both the first positioning clamp 3 and the second positioning clamp 4 are L-shaped; the fixing component 2 includes a first fixing clamp 2.1 and a second fixing clamp 2.2, the first fixing clamp 2.1 is slidably mounted on the first positioning clamp 3, the second fixing clamp 2.2 is slidably mounted on the second positioning clamp 4, and the second positioning clamp 4 is rotatably mounted on the first positioning clamp 3; the second... A rotating shaft 4.1 is fixedly installed on the positioning fixture 4. The rotating shaft 4.1 is in contact with the surface of the first positioning fixture 3. A snap-fit ​​plate 5 is fixedly installed at the bottom of both the first positioning fixture 3 and the second positioning fixture 4. A groove 6 is provided on the snap-fit ​​plate 5. A positioning groove 9 is provided on both the first positioning fixture 3 and the second positioning fixture 4. The first positioning component 1.1 and the second positioning component 1.2 are arranged in opposite directions. The groove 6 on the first positioning fixture 3 in the first positioning component 1.1 can be inserted into the groove 6 on the second positioning fixture 4 in the second positioning component 1.2. There are two sets of the first positioning component 1.1 and the second positioning component 1.2. The two sets of the first positioning component 1.1 and the second positioning component 1.2 are symmetrical to each other.

[0024] After the reinforcing bar is inserted into the ground, the positioning groove 9 on the first positioning clamp 3 of the first positioning component 1.1 is fastened onto the surface of the reinforcing bar, and the second positioning clamp 4 is rotated via the rotating shaft 4.1 so that the positioning groove 9 on the second positioning clamp 4 is fastened onto the surface of the reinforcing bar on the other side. At this time, the reinforcing bars on the adjacent two sides are initially positioned by the first positioning component 1.1. Then, the positioning groove 9 on the first positioning clamp 3 of the second positioning component 1.2 is fastened onto the surface of the reinforcing bar, and the second positioning clamp 4 is rotated via the rotating shaft 4.1 so that the positioning groove 9 on the second positioning clamp 4 is fastened onto the surface of the reinforcing bar on the other side. At this time, the reinforcing bars on the other two sides are initially positioned by the second positioning component 1.2. The groove 6 on the first positioning clamp 3 of the first positioning component 1.1 and the groove 6 on the second positioning clamp 4 of the second positioning component 1.2 are fastened together, and all four sides of the reinforcing bar are initially positioned. Finally, the reinforcing bar is fixedly installed inside the positioning groove 9 by the fixing component 2, thus completing the positioning of the reinforcing bar.

[0025] The first positioning fixture 3 has a first sliding groove 3.1. The first fixing fixture 2.1 has a first sliding block 2.11 fixedly installed on it. The first sliding block 2.11 is slidably installed in the first sliding groove 3.1. The first fixing fixture 2.1 has an L-shaped first fixing plate 2.12 fixedly installed at equal intervals. The first fixing plate 2.12 can close the opening of the positioning groove 9. The first fixing fixture 2.1 has an inclined plate 2.13 fixedly installed at one end near the rotating shaft 4.1.

[0026] When the first sliding block 2.11 slides inside the first sliding groove 3.1, it can drive the first fixing clamp 2.1 to slide on the first positioning clamp 3. When the first fixing clamp 2.1 slides, it can drive the first fixing plate 2.12 to move and close the opening of the positioning groove 9. At the same time, one side of the first fixing plate 2.12 can contact the surface of the steel bar and fix the steel bar on the first positioning clamp 3.

[0027] The positioning groove 9 on the second positioning fixture 4 is an arc shape with the rotation shaft 4.1 as the center. The end of the second positioning fixture 4 near the rotation shaft 4.1 is an arc surface. The second positioning fixture 4 has a second sliding groove 4.2. The first fixing fixture 2.1 is fixedly installed with a second sliding block 2.21. The second sliding block 2.21 is slidably installed in the first fixing fixture 2.2. The second fixing fixture 2.2 is fixedly installed with an L-shaped second fixing plate 2.22 at equal intervals. The second fixing plate can close the opening of the positioning groove 9. The end of the second fixing fixture 2.2 away from the rotation shaft 4.1 is fixedly installed with an inclined block 2.23.

[0028] When the second positioning clamp 4 rotates, the arc-shaped positioning groove 9 can be fitted onto the surface of the steel bar and initially position the steel bar. At the same time, when rotating, the arc surface on the second positioning clamp 4 can drive the inclined plate 2.13 to move and press the first fixing clamp 2.1 away from the rotating axis, causing the first fixing clamp 2.1 to move.

[0029] When the second sliding block 2.21 slides inside the second sliding groove 4.2, it can drive the second fixing clamp 2.2 to slide on the second positioning clamp 4. When the second fixing clamp 2.2 slides, it can drive the second fixing plate 2.22 to move and close the opening of the positioning groove 9. At the same time, one side of the second fixing plate 2.22 can contact the surface of the steel bar and fix the steel bar on the second positioning clamp 4.

[0030] A first connecting plate 3.2 is fixedly installed on the side of the first positioning clamp 3 away from the first fixing clamp 2.1. A first extension plate 2.14 is fixedly installed on the first sliding block 2.11. A first spring 2.15 is fixedly installed between the first connecting plate 3.2 and the first extension plate 2.14.

[0031] When the first sliding block 2.11 slides inside the first sliding groove 3.1, it can stretch the first spring 2.15. When the first spring 2.15 is not under force, the first spring 2.15 can pull the first sliding block 2.11 and drive the first fixing clamp 2.1 to return to its original position, so that the arc surface of the second positioning clamp 4 can contact the inclined plate 2.13 when used next time.

[0032] A second connecting plate 4.3 is fixedly installed on the side of the second positioning clamp 4 away from the second fixing clamp 2.2. A second extension plate 2.24 is fixedly installed on the first sliding block 2.11. A second spring 2.25 is fixedly installed between the second connecting plate 4.3 and the second extension plate 2.24.

[0033] When the second sliding block 2.21 slides inside the second sliding groove 4.2, it can stretch the second spring 2.25. When the second spring 2.25 is not under force, the second spring 2.25 can pull the second sliding block 2.21 and drive the second fixing clamp 2.2 to return to its original position.

[0034] A fixing rod 7 is provided at the rotating shaft 4.1 in the two sets of first positioning components 1.1. The two ends of the fixing rod 7 pass through the rotating shaft 4.1 respectively and are fixedly installed on the first positioning fixture 3 in the first positioning component 1.1.

[0035] The fixing rod 7 enables the two sets of positioning components 1 to be fixedly connected, allowing the two sets of positioning components 1 to be connected, and at the same time, it can position the two ends of the steel bar, so that the steel bar can be stably positioned.

[0036] Two sets of second positioning components 1.2 are provided with bidirectional threaded rods 8 at the rotating shaft 4.1. The two ends of the bidirectional threaded rods 8 pass through the rotating shaft 4.1 respectively and are threadedly connected to the first positioning fixture 3 in the second positioning component 1.2.

[0037] When the bidirectional threaded rod 8 rotates, it drives the two sets of positioning components 1 to move in opposite directions, so that the groove 6 on the first positioning clamp 3 in the first positioning component 1.1 and the groove 6 on the second positioning clamp 4 in the second positioning component 1.2 interlock. At the same time, when the first positioning clamp 3 moves in the opposite direction, the outer wall of the first positioning clamp 3 contacts the inclined block 2.23, and drives the second fixing clamp 2.2 to move, so that the steel bar is fixedly installed on the second positioning clamp 4. When the second spring 2.25 is no longer under force, the second positioning clamp 4 can return to its original position, so that the first positioning clamp 3 can contact the inclined block 2.23 when used next time. When it is necessary to remove it, the bidirectional threaded rod 8 is rotated in the opposite direction, so that the two sets of second positioning components 1.2 move away from each other and disengage the interlocking snap plate 5, so that the first fixing clamp 2.1 and the second fixing clamp 2.2 return to their original positions. The second positioning clamp 4 is rotated in the opposite direction, so that the steel bar is disengaged from the positioning groove 9, and the device is removed from the steel bar.

[0038] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
