Description

Technical Field

[0001] This invention relates to the field of rebar positioning technology, specifically to an adjustable rebar positioning device and its construction method. Background Technology

[0002] In the construction of concrete structures, especially in the reinforcement engineering of vertical components such as walls and columns, the positioning accuracy of the reinforcing bars is crucial to ensuring that the structural performance and the thickness of the protective layer meet design requirements. Reinforcing bar positioning clamps, as commonly used tools for controlling the spacing, row spacing, and protective layer thickness of reinforcing bars, are widely used on construction sites.

[0003] Currently, most traditional rebar positioning clamps used on construction sites are fixed-length structures. For example, common plastic or composite material clamps, and fixed-length welded "F-type" or "double F-type" clamps, have their dimensions and slot spacing fixed after manufacturing. In practical applications, construction workers need to select and customize clamps of appropriate specifications based on specific parameters such as wall thickness, rebar diameter, and rebar spacing specified in the design drawings.

[0004] However, existing rebar positioning clamps have the following drawbacks: First, its adaptability is poor. Because structural design parameters (such as wall thickness, rebar specifications, and spacing) often differ between different construction projects and even different floors and parts of the same project, fixed clamps are difficult to use universally. Construction companies are forced to prefabricate or purchase large quantities of different models of clamps for various specifications, which directly leads to two problems: on the one hand, it increases mold and material procurement costs; on the other hand, it complicates on-site material management, making it easy for clamps of various specifications to be confused, lost, or misused, significantly increasing management difficulty and warehousing pressure.

[0005] Secondly, when design changes occur during construction, or when components with non-standard cross-sectional dimensions are encountered, the prefabricated fixed clamps may become unusable and need to be re-customized, which seriously affects the construction progress and causes material waste. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable rebar positioning device and its construction method to solve the technical problem of positioning rebars with different spacings in the prior art.

An insertion hole is opened at the end of the positioning pin away from the positioning end head, and an R-type pin is inserted into the insertion hole.

[0011] Preferably, a first arc-shaped groove is formed at the end of the first connecting portion away from the second connecting portion, and a second arc-shaped groove is formed at the end of the second connecting portion away from the first connecting portion.

A locking rod is slidably embedded in the second connecting hole, and the locking rod is connected to a pushing part that drives it to slide along the second connecting hole. The snap-fit ​​portion includes a wedge-shaped slot formed on the snap-fit ​​rod, and a wedge-shaped seat for engaging with the wedge-shaped slot is provided in the first connecting portion near the first connecting hole.

[0014] Preferably, an L-shaped bracket is fixedly arranged on one side of the first connecting hole, and an adjusting rod that is fixedly connected to the wedge-shaped card seat is slidably inserted in the L-shaped bracket, and a first spring is provided on the adjusting rod; The inclined surface of the wedge-shaped card holder faces the first connecting hole.

The second slide is slidably connected to a second guide rod that is fixedly arranged in the second connecting part. A third spring is provided on the second guide rod.

[0016] A construction method for an adjustable rebar positioning device, applied to the aforementioned adjustable rebar positioning device, includes the following steps: Before positioning the main body of the reinforcing bars, based on the preset spacing between two sets of adjacent main bodies of the reinforcing bars, the first connecting part and the second connecting part in the main body of the clamp are adjusted by the adjustment mechanism so that the positioning distance of each set of clamp bodies to each of the two sets of adjacent main bodies of the reinforcing bars remains consistent. During the positioning process, for two adjacent sets of steel reinforcement bodies, the clamp body is connected to one set of steel reinforcement bodies through the first connecting part and to the other set of steel reinforcement bodies through the second connecting part.

[0017] Compared with the prior art, the beneficial effects of this application are as follows: 1. In the positioning process of this invention, the position of each main body of a steel bar in any column of steel bars is first positioned by the first positioning part, so that the spacing of each main body of a steel bar in any column of steel bars is the same as the preset value, and the spacing of each pair of adjacent main bodies of steel bars is consistent. Then, the position of the first column of steel bars and the second column of steel bars is positioned by the second positioning part, so that the spacing of each pair of main bodies of steel bars in the corresponding positions in the first column of steel bars and the second column of steel bars is also consistent, so as to achieve the effect of positioning each main body of steel bar.

[0018] 2. In the positioning process of this invention, for two adjacent sets of steel reinforcement bodies, they are connected by the first connecting part and the second connecting part of the clamp body respectively. Before the connection, based on the preset spacing between the two sets of adjacent steel reinforcement bodies, the first connecting part and the second connecting part in the clamp body can be adjusted in advance by the adjustment mechanism, so that in the subsequent positioning process of the steel reinforcement bodies, the positioning distance of each clamp body to each of the two sets of adjacent steel reinforcement bodies remains consistent.

[0019] 3. This invention positions two adjacent sets of reinforcing bars by setting up a clamp body. At the same time, based on the arrangement requirements of the reinforcing bars, the first and second connecting parts of each clamp body are adjusted in advance by an adjustment mechanism, so that the positioning distance between each set of clamp bodies and the two sets of adjacent reinforcing bars remains consistent during subsequent positioning, thereby improving the accuracy and stability of the reinforcing bar arrangement and facilitating subsequent construction.

[0020] 4. By setting a push rod, the present invention automatically pushes the clamping rod out of the second connecting hole during the fitting and connection process of the first and second connecting parts. When disassembling, the second and third springs can automatically drive each component to reset. The present invention does not require other servo drive equipment to adjust the operation of the clamping rod. Based on the process of two sets of adjacent clamping bodies being connected end to end, the two sets of clamping bodies can be automatically engaged. When disassembly is required, the construction personnel only need to pull the adjusting rod to drive the wedge-shaped clamping seat to separate from the wedge-shaped clamping groove, which is very convenient to operate.

Detailed Implementation

[0023] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0024] Example 1 Existing rebar positioning clamps are usually of fixed length, which makes it difficult for them to meet application requirements when positioning rebars with different spacings.

[0025] like Figures 1 to 5 In this embodiment, an adjustable rebar positioning device includes a positioning module for positioning the first row of rebars 1 and the second row of rebars 101 before the concrete wall is poured. Specifically, the first row of reinforcing bars 1 and the second row of reinforcing bars 101 are arranged in parallel and symmetrical manner, wherein the first row of reinforcing bars 1 and the second row of reinforcing bars 101 each include several groups of reinforcing bar bodies 102 arranged at equal intervals; In this embodiment, the positioning module includes a first positioning part 2, which is used to position the main body 102 of each steel bar in any column of steel bars; It also includes a second positioning part 201, which is used to position the first column of reinforcing bars 1 and the second column of reinforcing bars 101. It should be noted that, in this embodiment, during positioning, the first positioning part 2 is used to position the position of each reinforcing bar body 102 in any column of reinforcing bars, so that the spacing of each reinforcing bar body 102 in any column of reinforcing bars is the same as the preset value, and the spacing of each pair of adjacent reinforcing bar bodies 102 is consistent. Then, the second positioning part 201 is used to position the first column of reinforcing bars 1 and the second column of reinforcing bars 101, so that the spacing of each pair of reinforcing bar bodies 102 in the corresponding positions in the first column of reinforcing bars 1 and the second column of reinforcing bars 101 is also consistent, so as to achieve the effect of positioning each reinforcing bar body 102.

[0026] As a further embodiment, both the first positioning part 2 and the second positioning part 201 include at least one set of clamp bodies 3, with each clamp body 3 connected end to end for positioning and fixing two sets of adjacent steel bar bodies 102. Each set of clamp bodies 3 includes a first connecting part 4 and a second connecting part 5. For two sets of adjacent steel bar bodies 102, the first connecting part 4 is used to connect with one set of steel bar bodies 102, and the second connecting part 5 is used to connect with the other set of steel bar bodies 102. Specifically, when the clamp body 3 of this embodiment positions two sets of adjacent steel bar bodies 102, the first connecting part 4 can position and fix one set of steel bar bodies 102, and the second connecting part 5 can position and fix the other set of steel bar bodies 102 to ensure the stability of the positioning of the two sets of adjacent steel bar bodies 102. Furthermore, the clamp body 3 also includes an adjustment mechanism, which is used to adjust the relative distance between the first connecting part 4 and the second connecting part 5 after positioning the two sets of adjacent steel bar bodies 102, so as to adapt to different steel bar spacing requirements. The working principle of this embodiment is as follows: Figures 1-3 As shown, in this embodiment, when positioning the first column of reinforcing bars 1 and the second column of reinforcing bars 101, the first positioning part 2 and the second positioning part 201 can cooperate to accurately position the position of each group of reinforcing bar bodies 102. Specifically, during the positioning process, for two adjacent groups of reinforcing bar bodies 102, they are connected by the first connecting part 4 and the second connecting part 5 of the clamp body 3, respectively. Before the connection, based on the preset distance between the two groups of adjacent reinforcing bar bodies 102, the first connecting part 4 and the second connecting part 5 in the clamp body 3 can be adjusted in advance by the adjustment mechanism, so that during the subsequent positioning of the reinforcing bar bodies 102, the positioning distance of each clamp body 3 to each of the two groups of adjacent reinforcing bar bodies 102 remains consistent.

[0027] It should be emphasized that the core improvement of this embodiment is that: this embodiment uses a clamp body 3 to position two sets of adjacent steel bar bodies 102. At the same time, based on the arrangement requirements of the steel bars, the first connecting part 4 and the second connecting part 5 of each clamp body 3 are adjusted in advance by an adjustment mechanism, so that the positioning distance between each set of clamp bodies 3 and the two sets of adjacent steel bar bodies 102 is consistent during subsequent positioning, thereby improving the accuracy and stability of the steel bar body 102 arrangement and facilitating subsequent construction.

[0028] It should be noted that, such as Figures 4-8 as well as Figure 10 Both the first connecting part 4 and the second connecting part 5 are configured as U-shaped structures, and the lengths of the first connecting part 4 and the second connecting part 5 are the same. The second connecting part 5 is slidably arranged in the first connecting part 4. It can be noted that the first connecting part 4 and the second connecting part 5 in this embodiment are made of aluminum alloy material. By making the second connecting part 5 retractable and slidable in the first connecting part 4, the relative position of the first connecting part 4 and the second connecting part 5 can be adjusted by the adjustment mechanism.

[0029] To ensure the stability of the sliding connection between the first connecting part 4 and the second connecting part 5, in this embodiment, a T-shaped groove 403 is formed on the inner wall of the first connecting part 4, and a T-shaped slide block 505 is correspondingly fixedly arranged on the outer wall of the second connecting part 5, which is slidably connected to the T-shaped groove 403. Specifically, by setting the T-shaped slide block 505 to cooperate with the T-shaped groove 403, when the first connecting part 4 and the second connecting part 5 slide relative to each other, the T-shaped slide block 505 slides synchronously in the T-shaped groove 403, so as to achieve the effect of limiting and guiding the second connecting part 5.

[0030] In this embodiment, the adjustment mechanism includes several sets of first positioning holes 401 equidistantly opened on the first connecting part 4 and several sets of second positioning holes 501 equidistantly opened on the second connecting part 5. The adjustment mechanism also includes positioning pins 6 for inserting and cooperating with the first positioning holes 401 and the second positioning holes 501. The end of the positioning pin 6 is integrally provided with a positioning end head 601, and the diameter of the positioning end head 601 is larger than the inner diameter of the first positioning holes 401 and the second positioning holes 501. Specifically, in this embodiment, when adjusting the relative position of the first connecting part 4 and the second connecting part 5, the relative position of the second connecting part 5 and the first connecting part 4 can be adjusted based on the distance between the two sets of adjacent steel bar bodies 102 to be positioned, so that the positions of the first positioning holes 401 on the first connecting part 4 and the second positioning holes 501 on the second connecting part 5 correspond. Then, the positioning pins 6 are inserted into the corresponding first positioning holes 401 and second positioning holes 501 to achieve the effect of positioning the first connecting part 4 and the second connecting part 5, and to prevent the two from sliding relative to each other again.

[0031] It should be noted that, such as Figures 6-10 To ensure the stability of the positioning pin 6 when inserted into the first positioning hole 401 and the second positioning hole 501, in this embodiment, an insertion hole 602 is opened at the end of the positioning pin 6 away from the positioning end 601, and an R-shaped pin 603 is inserted into the insertion hole 602. Specifically, in this embodiment, after the positioning pin 6 is inserted into the first positioning hole 401 and the second positioning hole 501, the end of the positioning pin 6 away from the positioning end 601 extends to the outside of the first positioning part 2. The construction personnel then insert the R-shaped pin 603 into the insertion hole 602 to achieve the locking and fixing of the positioning pin 6, thereby ensuring the stability of the positioning pin 6 and preventing the positioning pin 6 from falling off. Therefore, when it is necessary to disassemble or adjust the first connecting part 4 and the second connecting part 5 after connection in this embodiment, the R-type pin 603 is first pulled out from the insertion hole 602, and then the positioning pin 6 is pulled out from the first positioning hole 401 and the second positioning hole 501. The operation is very convenient.

[0032] In order to position the steel bar body 102 through the first connecting part 4 and the second connecting part 5, in this embodiment, please refer to Figures 5-7 A first arc-shaped groove 402 is formed at the end of the first connecting part 4 away from the second connecting part 5, and a second arc-shaped groove 502 is formed at the end of the second connecting part 5 away from the first connecting part 4. Both the first arc-shaped groove 402 and the second arc-shaped groove 502 are semi-circular grooves with equal diameters, for embedding two sets of adjacent steel bar bodies 102 to be positioned. It should be noted that in this embodiment, when positioning two sets of adjacent steel bar bodies 102, one set of steel bar bodies 102 is fitted into the first arc-shaped groove 402, and the other set of steel bar bodies 102 is fitted into the second arc-shaped groove 502. The first arc-shaped groove 402 and the second arc-shaped groove 502 achieve the effect of initially limiting the steel bar bodies 102.

[0033] The core improvement of this embodiment is that, for the first column of reinforcing bars 1 and the second column of reinforcing bars 101, since each column is provided with multiple sets of reinforcing bar bodies 102, each set of reinforcing bar bodies 102 is provided with a set of clamping bodies 3 on both sides. The two sets of clamping bodies 3 are connected end to end on both sides of the reinforcing bar body 102. The first arc groove 402 in one set of clamping bodies 3 and the second arc groove 502 in the other set of clamping bodies 3 form a complete positioning circular groove, which can further improve the positioning effect of the reinforcing bar body 102, making the reinforcing bar body 102 more stable and preventing it from detaching from a single arc groove. Correspondingly, for the main body 102 of the steel bars at both ends, this embodiment can set a set of clamping bodies 3 to limit them, thereby ensuring that each main body 102 of the steel bars can be limited by the complete positioning groove.

[0034] In addition, when the clamp body 3 is connected to the steel bar body 102, in order to ensure the stability of the clamp body 3 on the steel bar body 102, in this embodiment, the first arc groove 402 and the second arc groove 502 are provided with spiral grooves 7 corresponding to the spiral ribs on the outer wall of the steel bar body 102. During the installation process, the spiral grooves 7 can engage with the spiral ribs to ensure positioning stability.

[0035] Example 2 It is understandable that in Embodiment 1, after the clamp body 3 is installed, the two sets of clamp bodies 3 connected end to end are independent of each other, and thus the stability of the clamp body 3 cannot be guaranteed. like Figures 5 to 9 To solve the above problems, a snap-fit ​​part is provided between two sets of adjacent clamp bodies 3. The snap-fit ​​part is used to connect the first connecting part 4 of one set of clamp bodies 3 to the second connecting part 5 of another set of clamp bodies 3. Specifically, in the process of positioning the steel bar body 102 by connecting the first connecting part 4 of one set of clamp bodies 3 to the second connecting part 5 of another set of clamp bodies 3, the connection and fixation of the two sets of adjacent clamp bodies 3 are realized. In this embodiment, a first connecting hole 405 is provided at the end of the first connecting part 4 away from the second connecting part 5, and a second connecting hole 503 is provided at the end of the second connecting part 5 away from the first connecting part 4. A locking rod 9 is slidably embedded in the second connecting hole 503. The locking rod 9 is connected to a pushing part that drives it to slide along the second connecting hole 503. The locking part includes a wedge-shaped groove 904 opened on the locking rod 9. A wedge-shaped seat 408 for engaging with the wedge-shaped groove 904 is provided in the first connecting part 4 at a position close to the first connecting hole 405. The working principle of this embodiment is as follows: Figures 5-9 As shown, in the initial state, the clamping rod 9 is retracted into the second connecting hole 503. In this embodiment, when connecting two sets of adjacent clamping bodies 3, the first connecting part 4 in one set of clamping bodies 3 fits into the second connecting part 5 in the other set of clamping bodies 3, so that the first connecting hole 405 on the first connecting part 4 corresponds to the second connecting hole 503 on the second connecting part 5. Then, the clamping rod 9 is driven by the pushing part to extend out of the second connecting hole 503 and embed into the first connecting hole 405. Finally, the connection and positioning of the first connecting part 4 and the second connecting part 5 can be achieved by the wedge-shaped clamping seat 408 and the wedge-shaped clamping groove 904 engaging. Correspondingly, when it is necessary to disconnect the connection between the first connecting part 4 and the second connecting part 5, the wedge-shaped card holder 408 and the wedge-shaped card groove 904 can be separated, which is very convenient.

[0036] It should be emphasized that the core improvement of this embodiment is that: during the connection process, the first connecting part 4 and the second connecting part 5 of this embodiment can be engaged by the wedge-shaped card seat 408 and the wedge-shaped card groove 904. After engagement, the two sets of adjacent card bodies 3 cannot be displaced relative to each other, thereby keeping the steel bar body 102 in a stable state in the positioning groove and achieving the effect of precise positioning.

[0037] It should be noted that, such as Figure 9 When the locking rod 9 is inserted into the first connecting hole 405, in order to facilitate the adjustment of the relative position of the wedge-shaped locking seat 408 and the wedge-shaped locking groove 904, an L-shaped bracket 404 is fixedly arranged on one side of the first connecting hole 405. An adjusting rod 406 fixedly connected to the wedge-shaped locking seat 408 is slidably inserted in the L-shaped bracket 404. A first spring 407 is provided on the adjusting rod 406. One end of the first spring 407 is fixedly connected to the L-shaped bracket 404, and the other end is fixedly connected to the end of the locking rod 9. The inclined surface of the wedge-shaped locking seat 408 faces the first connecting hole 405. 05; It can be explained that during the process of driving the locking rod 9 to be inserted into the first connecting hole 405, the locking rod 9 first abuts against the inclined surface of the wedge-shaped locking seat 408. As the locking rod 9 continues to move, the adjusting rod 406 can be pushed to slide away from the first connecting part 4 through the wedge-shaped locking seat 408. During the movement of the locking rod 9, the first spring 407 is compressed and elastic force is generated. As the wedge-shaped locking seat 408 moves to the position of the wedge-shaped locking groove 904, the first spring 407 drives the wedge-shaped locking seat 408 to reset and lock into the wedge-shaped locking groove 904. It should be noted that, such as Figures 7-9 As shown, the pushing part includes a gear 805 rotatably arranged in the second connecting part 5. A first rack 901, meshing with one side of the gear 805, is fixedly arranged at one end of the lever 9 near the second connecting part 5. A first slide 902 is fixedly arranged at the end of the first rack 901 away from the lever 9. The first slide 902 is slidably connected to a first guide rod 903 fixedly arranged in the second connecting part 5. A second spring 804 is provided on the first guide rod 903. One end of the second spring 804 is fixedly connected to the first slide 902, and the other end is fixedly connected to the first guide rod 903. The second connecting hole 5... 03 A third connecting hole 504 is opened at the bottom. A push rod 8 is slidably embedded in the third connecting hole 504. A second rack 801 that meshes with the other side of the gear 805 is fixedly arranged at one end of the push rod 8 near the second connecting part 5. A second slide 802 is fixedly arranged at the other end of the second rack 801 away from the push rod 8. The second slide 802 is slidably connected to the second guide rod 803 fixedly arranged in the second connecting part 5. A third spring 806 is provided on the second guide rod 803. One end of the third spring 806 is fixedly connected to the second slide 802, and the other end is fixedly connected to the end of the second guide rod 803. The working principle of this embodiment is as follows: In the initial state, the push rod 8 is in the state of extending out of the third connecting hole 504, and the locking rod 9 is in the state of being embedded in the second connecting hole 503. When the first connecting part 4 and the second connecting part 5 are in contact with each other, the first connecting part 4 can push the push rod 8 to move in the direction of being embedded in the third connecting hole 504. During this process, the push rod 8 drives the gear 805 to rotate by cooperating with the second rack 801. During the rotation of the gear 805, it pushes the locking rod 9 to move into the first connecting hole 405 by meshing with the first rack 901, so as to realize the subsequent engagement of the wedge-shaped locking seat 408 and the wedge-shaped locking groove 904. During the movement of the first rack 901 and the second rack 801, they can compress the second spring 804 and the third spring 806 respectively and generate elastic force, so as to drive the subsequent reset of each component.

[0038] It should be emphasized that the core improvement of this embodiment is that, by setting the push rod 8, the first connecting part 4 and the second connecting part 5 automatically push the clamping rod 9 out of the second connecting hole 503 during the fitting and connection process. When disassembling, the second spring 804 and the third spring 806 can automatically drive each component to reset. This embodiment does not require setting other servo drive devices to adjust the technical effect of the clamping rod 9. Based on the process of two sets of adjacent clamping bodies 3 being connected end to end, the effect of automatic clamping of the two sets of clamping bodies 3 can be achieved. When disassembly is required, the construction personnel only need to pull the adjusting rod 406 to drive the wedge-shaped clamping seat 408 to separate from the wedge-shaped clamping groove 904, which is very convenient to operate.
