Description

Technical Field

[0001] This invention relates to building construction, specifically to a reusable PC precast column rebar conversion and positioning device. Background Technology

[0002] The connection between precast PC columns and cast-in-place columns requires rebar conversion. Currently, the common practice is to directly use the original cast-in-place column rebar. The advantage is that it can save rebar, but the disadvantage is that the rebar positioning is relatively difficult. It is easy for the rebar to be fixed in an skewed position due to the casting process, which will affect the subsequent installation of the precast PC column.

[0003] Another method of rebar conversion involves rearranging the dowel bars. Its advantage is relatively accurate positioning, but its disadvantage is increased rebar usage. Therefore, it can be seen that among the current conversion methods, the lower-cost solution is more difficult to position, while the more accurate positioning solution is more expensive. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a reusable PC precast column rebar conversion and positioning device that can improve the positioning effect while maintaining a low cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A reusable PC precast column rebar conversion and positioning device, comprising... The first positioning component has several first through holes for the reinforcing bars to pass through, corresponding to the reinforcing bars of the cast-in-place column; The second positioning component has several second through holes for the reinforcing bars to pass through, corresponding to the reinforcing bars of the cast-in-place column; The first positioning member is provided with a first positioning hole, and the second positioning member is provided with a second positioning hole at the position corresponding to the first positioning hole; a positioning rod is detachably mounted on the second positioning member, and the positioning rod passes through the second positioning hole and then through the first positioning hole to correct the first positioning member and the second positioning member. The diameters of both the first and second through holes are larger than the reinforcing bars.

[0006] As a further improvement of the present invention, the first positioning hole and the second positioning hole corresponding to the position are a set, and multiple sets are provided on the first positioning member and the second positioning member.

[0007] As a further improvement of the present invention, an adjusting member is provided between the first positioning member and the second positioning member, and the adjusting member raises the second positioning member by adjusting its length.

[0008] As a further improvement of the present invention, the number of the adjusting members is at least two, and they are respectively arranged on both sides of the first positioning member.

[0009] As a further improvement of the present invention, the adjusting member includes a support member for engaging with the first positioning member and a telescopic member that is retractably connected to the support member, wherein the telescopic member lifts the second positioning member by extending and retracting.

[0010] As a further improvement of the present invention, a positioning clip is hinged to the support member, and the support member has a slide for the telescopic member to pass through and telescopically extend. The telescopic member is slidably connected in the slide, and a plurality of annular positioning rings are provided on the side of the telescopic member. The positioning rings are coaxially arranged with the telescopic member and are used to cooperate with the positioning clip to support and position the telescopic member. The positioning clip is provided with an elastic component so as to embed the positioning clip between adjacent positioning rings by elastic force.

[0011] As a further improvement of the present invention, the end of the positioning ring facing the second positioning member is provided with an inclined surface. When the telescopic member extends from the slide, the inclined surface on the positioning ring pushes open the positioning clamp.

[0012] As a further improvement of the present invention, several adjacent positioning rings are grouped together, and each positioning ring in the group has a different color and is distributed in a regular pattern, and a group of positioning rings includes at least 7 rings.

[0013] As a further improvement of the present invention, the positioning ring is printed with a scale pattern to form a scale mark at the slide opening on the support member.

[0014] As a further improvement of the present invention, a scale wheel is provided on the support member, and the side of the scale wheel is provided with teeth that are adapted to the positioning ring. When the telescopic member moves in and out, it drives the scale wheel to rotate so as to switch the scale displayed by the scale wheel.

[0015] The beneficial effects of this invention are: 1. It provides a turnover function, saves costs, and allows the original cast-in-place column reinforcement to be straighter after casting. 2. Since the diameters of the first and second through holes are both larger than the diameter of the reinforcement, it facilitates the installation of the first and second positioning components. Simultaneously, the first and second through holes provide space for straightening the reinforcement. Some bent reinforcements will abut against the edge, while straighter reinforcements will not. Prying the positioning rod allows the second positioning component to move, thereby straightening the reinforcement abutting the edge. When most of the reinforcement on the second positioning component abuts against the edge of the second through hole, significant resistance is generated, limiting further prying and preventing "over-straightening" that could cause other reinforcements to bend.

[0017] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-6 As shown, A reusable precast PC column rebar transfer and positioning device, comprising: The first positioning component 1 has several first through holes 11 for the reinforcing bars to pass through, corresponding to the reinforcing bars of the cast-in-place column; The second positioning component 2 is provided with several second through holes 21 for the reinforcing bars to pass through, corresponding to the reinforcing bars of the cast-in-place column; The first positioning member 1 is provided with a first positioning hole 12, and the second positioning member 2 is provided with a second positioning hole 22 at the position corresponding to the first positioning hole 12; a positioning rod 3 is detachably installed on the second positioning member 2, and the positioning rod 3 passes through the second positioning hole 22 and then passes through the first positioning hole 12 to correct the first positioning member 1 and the second positioning member 2. The diameters of the first through hole 11 and the second through hole 21 are both larger than the reinforcing bar.

[0019] This solution can reduce the cost of straightening the reinforcing bars in cast-in-place columns, allows for reuse, and facilitates connection with precast PC columns by directly casting the original reinforcing bars.

[0020] During use, first, the first positioning piece 1 is placed on the cast-in-place column reinforcement, allowing the cast-in-place column reinforcement to pass through the corresponding first through hole 11 and press it to the bottom. Then, the second positioning piece 2 is placed on the cast-in-place column reinforcement, allowing the cast-in-place column reinforcement to pass through the second positioning piece 2. Then, the positioning rod 3 passes through the second positioning hole 22 and the first positioning hole 12 from top to bottom. The positioning rod 3 can be used to determine whether the current cast-in-place column reinforcement is in a relatively straight state. If it is not straight, the first positioning hole 12 can be used as a fulcrum and the positioning rod 3 can be used as a lever to pry the second positioning piece 2 to correct the cast-in-place column reinforcement. Since the diameters of the first through hole 11 and the second through hole 21 are both larger than the diameter of the reinforcing bar, it facilitates the installation between the first positioning member 1 and the second positioning member 2. Simultaneously, the first through hole 11 and the second through hole 21 can provide space for straightening the reinforcing bar. For example, some bent reinforcing bars may abut against the edge, while straighter reinforcing bars will not. In this case, prying the positioning rod 3 allows the second positioning member 2 to move, thereby straightening the reinforcing bar that is abutting against the edge. When most of the reinforcing bars on the second positioning member 2 abut against the edge of the second through hole 21, significant resistance is generated, thus limiting the user from further prying and preventing "over-straightening" that could cause other reinforcing bars to bend. This allows the user to straighten individual reinforcing bars while also preventing "over-straightening." Furthermore, after straightening, the second positioning member 2 can be moved upwards to gradually straighten the various positions of the reinforcing bar. After straightening, it can be retracted. The first positioning hole 12 and the corresponding second positioning hole 22 form a group, and four groups can be set, located in four directions respectively.

[0021] Before use, the first positioning component 1 and the second positioning component 2 can be marked with information such as building, floor, front and back sides for easy use.

[0022] In fact, the positioning rod 3 can be used only for positioning to ensure the stability between the first positioning member 1 and the second positioning member 2, while the second positioning member 2 serves as a support. The steel bar can be bent with the help of tools to achieve correction. The second positioning member 2 is only used as a lateral support to facilitate correction.

[0023] Furthermore, to facilitate the support and positioning of the second positioning member 2 and make it easier to correct its height, an adjusting member 4 is provided between the first positioning member 1 and the second positioning member 2. The adjusting member 4 raises the second positioning member 2 by adjusting its length. Each time the second positioning member 2 is moved, adjusting members 4 of different lengths can be placed between the first positioning member 1 and the second positioning member 2 to support the second positioning member 2, keeping it at the corresponding height for correction.

[0024] Preferably, the adjusting member 4 can be sleeved on the cast-in-place column reinforcement. The adjusting member 4 is provided with a through hole corresponding to the diameter of the cast-in-place column reinforcement, so that the cast-in-place column reinforcement can pass through the through hole and the adjusting member 4 can be sleeved on the cast-in-place column reinforcement. With this structure, the adjusting member 4 can maintain the state of the already straightened reinforcement and avoid subsequent bending.

[0025] After each correction using the second positioning element 2, the adjusting elements 4 can be stacked. In this design, the adjusting element 4 can be a ring structure with openings on the sides, allowing it to be engaged with the reinforcing bars from the side. This provides support, and the number of adjusting elements 4 can be selected for engagement and adjustment as the height of the second positioning element 2 moves.

[0026] Alternatively, one-piece adjusting pieces 4 of different lengths can be selected. After the second positioning piece 2 has corrected the corresponding position of the rebar, the second positioning piece 2 can be removed, and then the longer adjusting piece 4 can be fitted onto the rebar before the second positioning piece 2 is installed back onto the rebar. However, this method requires a larger quantity of adjusting pieces 4.

[0027] As a preferred example, the number of adjustment members 4 is at least two, and they are respectively arranged on both sides of the first positioning member 1.

[0028] The number of adjusting parts 4 is two, which can provide better support for the second positioning part 2 and better balance.

[0029] To further facilitate use, the adjusting member 4 includes a support member 41 for engaging with the first positioning member 1 and a telescopic member 42 that is telescopically connected to the support member 41. The telescopic member 42 lifts the second positioning member 2 by telescopic movement.

[0030] In this example, the adjusting member 4 is telescopic, and the telescopic member 42 cooperates with the telescopic member 41 to extend and retract, using the telescopic action to provide positioning support and keep the second positioning member 2 stably in the corresponding position. The telescopic member 42 can be telescopically extended and retracted through a threaded connection, and the telescopic member 42 uses the threaded engagement to perform the telescopic action during rotation. In this structure, the reinforcing bar can also be in a state of passing through the support member 41 and the telescopic member 42.

[0031] In another example, a positioning clip 43 is hinged to the support member 41. The support member 41 has a slide 44 through which a telescopic member 42 passes and extends. The telescopic member 42 is slidably connected in the slide 44, and several annular positioning rings 45 are provided on the side of the telescopic member 42. The positioning rings 45 are coaxially arranged with the telescopic member 42 and are used to support and position the telescopic member 42 in conjunction with the positioning clip 43. The positioning clip 43 is provided with an elastic member 46 to elastically embed the positioning clip 43 between adjacent positioning rings 45. The elastic member 46 can be a torsion spring, which can provide a tendency for the positioning clip 43 to move towards the positioning rings 45.

[0032] The positioning clip 43 is hinged to the support member 41. When the telescopic member 42 slides to extend or retract, the positioning clip 43 is embedded between two adjacent positioning rings 45 by means of a component (such as a torsion spring). The cooperation between the positioning rings 45 and the positioning clip 43 supports the telescopic member 42, preventing it from sliding into the slide rail 44. In this configuration, the position of each telescopic member 42 can be determined based on the position of the positioning rings 45, thereby maintaining the balance of the second positioning member 2.

[0033] In order to facilitate the extension of the telescopic component 42, the end of the positioning ring 45 facing the second positioning component 2 is provided with a slope 47. When the telescopic component 42 extends from the slide rail 44, the slope 47 on the positioning ring 45 pushes open the positioning clamp 43.

[0034] In this structure, as the telescopic member 42 extends outward, the positioning clamp 43 will automatically engage with the inclined surface 47, thereby opening the positioning clamp 43 to facilitate adjustment when moving the second positioning member 2.

[0035] In addition, several examples are provided below to help users keep the extended lengths of multiple telescopic components 42 consistent.

[0036] 1. Several adjacent positioning rings 45 form a group, and each positioning ring 45 in the group has a different color and is distributed according to a pattern. Each group of positioning rings 45 includes at least 7 rings. In this solution, different colored markers are used to indicate the corresponding positions. For example, there are at least 7 positioning rings 45, which can provide a certain level of identification. If the length of a group is exceeded, it can be clearly observed by the naked eye that the support of the second positioning component 2 is unbalanced. Then, the current position can be identified by observing the colors. For example, 7 positioning rings 45 require 7 different colors, such as red, orange, yellow, green, indigo, blue, and purple. The color pattern on each telescopic component 42 is the same, and the corresponding positions are also the same, allowing the user to quickly identify the current extension length of the telescopic component 42 during use.

[0037] 2. The positioning ring 45 is printed with a scale pattern to form a scale mark at the opening of the slide rail 44 on the support member 41. The scale is directly painted on the positioning ring 45, and the opening of the slide rail 44 serves as a marker point. The length of the extension of the telescopic member 42 can be directly read through the marker point.

[0038] 3. A graduated wheel 48 is provided on the support member 41. The side of the graduated wheel 48 has teeth that are adapted to the positioning ring 45. When the telescopic member 42 extends and retracts, it drives the graduated wheel 48 to rotate, thereby switching the scale displayed on the graduated wheel 48. In this solution, the graduated wheel 48 is rotatably connected to the support member 41. As the telescopic member 42 extends and retracts, the positioning ring 45 will rotate the graduated wheel 48. For example, the graduated wheel 48 is marked with numbers 1 to 9, which can reflect the current extension state of the telescopic member 42. Of course, the graduated wheel 48 is in a cyclic state, but a set is marked with 1 to 9, so the length exceeding the set can be observed with the naked eye. In addition, the graduated wheel 48 can abut against the telescopic member 42, making the cooperation between the telescopic member 42 and the positioning ring 45 more stable and reducing the loosening and shaking of the telescopic member 42.

[0039] The above describes a reusable PC precast column rebar conversion and positioning device. Based on this structure, a precast column rebar conversion and positioning method can also be provided.

[0040] Step 1: Install the first positioning component 1 on the cast-in-place column reinforcement, and let the cast-in-place column reinforcement pass through the first through hole 11; Step 2: Install adjustment piece 4 on the cast-in-place column reinforcement, and let the cast-in-place column reinforcement pass through adjustment piece 4; Step 3: Install the second positioning piece 2 on the cast-in-place column reinforcement, with the cast-in-place column reinforcement passing through the second through hole 21; Step 4: Pass the positioning rod 3 through the second positioning hole 22 and the first positioning hole 12, and use the first positioning hole 12 as a fulcrum to pry the second positioning component 2 to straighten the cast-in-place column reinforcement. Step 5: Adjust the position of the second positioning member 2 and support the second positioning member 2 by adjusting member 4; Step 6: Repeat steps 4-5 until the cast-in-place column reinforcement is straightened, then remove positioning rod 3, second positioning piece 2, adjusting piece 4, and first positioning piece 1.

[0041] The support method of the adjusting member 4 supporting the second positioning member 2 can adopt the implementation method mentioned in the reusable PC precast column steel bar conversion and positioning device.

It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
