Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and in particular to a binding tool and method for precast wall steel reinforcement cages. Background Technology

[0002] With the advancement and development of construction technology, the prefabricated component usage rate is increasing, and rebar cages, as an essential component of prefabricated structures, are in ever-growing demand. Rebar cage forming methods are divided into online forming and offline forming. For online forming, the rebars need to be assembled and tied manually on a mold. Since the tying process occupies the mold, affecting its utilization rate and overall processing efficiency, offline forming is generally preferred for processing rebar cages. Offline forming of rebar cages requires the use of rebar cage forming fixtures.

[0003] Taking the steel reinforcement cage of a precast wall as an example, when forming the steel reinforcement cage using existing steel reinforcement cage forming tools, it is necessary to first process the beams, columns, and mesh panels separately, and then select the beams, columns, and mesh panels according to the target structure of the steel reinforcement cage, and assemble them to form a complete steel reinforcement cage. Both the beams and columns have multiple longitudinal bars and multiple stirrups fitted outside the longitudinal bars; that is, the beams and columns themselves are also mesh-like structures. During assembly, each longitudinal bar of the beam needs to be inserted into the mesh space between the different longitudinal bars and stirrups of the column, which presents problems of inconvenience in alignment and difficulty in insertion.

[0004] Therefore, how to solve the problem of insertion difficulties when forming steel cages using existing steel cage forming tools has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0023] The present invention also provides a method for binding precast wall reinforcement cages, based on the binding fixtures for precast wall reinforcement cages as described above, the method for binding precast wall reinforcement cages includes:

[0024] The first and second steel cages are placed on the first and second support rods, respectively, with the axial direction of the first and second steel cages along the longitudinal direction and the first and second steel cages distributed along the transverse direction.

[0025] A target number of third stirrups are placed above the second support rod, and each of the third stirrups is distributed along the transverse direction;

[0026] The target number of third longitudinal bars are sequentially passed through the first steel cage, each of the third stirrups, and the second steel cage;

[0027] One end of a portion of the third longitudinal reinforcement is fixedly connected to the upper edge of the first steel cage and the upper edge of the second steel cage, respectively, and then fixedly connected to the third stirrup.

[0028] Remove the support shaft and the second support rod located below the third longitudinal rib from the base frame;

[0029] The two ends of the remaining third longitudinal bars are fixedly connected to the lower edge of the first steel cage and the lower edge of the second steel cage, respectively, and fixedly connected to the third stirrups. The third longitudinal bars and the third stirrups are connected to form the third steel cage.

[0030] A pair of mesh panels are connected to the first, second, and third reinforcing cages, and the mesh panels are reinforced.

[0031] The precast wall reinforcement cage binding tool provided by this invention includes a base frame and a transverse support assembly. The transverse support assembly includes a first support rod and a second support rod extending transversely. The first support rod is fixedly installed at one end of the base frame. A support seat is provided on the base frame, with an opening at the bottom, and the support seat is fixedly connected to the base frame. At least two second support rods are provided, with the first support rod and each second support rod distributed longitudinally at intervals. Each second support rod is correspondingly installed with a support seat via a support shaft, and the end of the second support rod is detachably connected to the support shaft, which is also detachably connected to the support seat. When forming a precast wall reinforcement cage using the precast wall reinforcement cage binding tool provided by this invention, two pre-bound column reinforcement cages are placed on the base frame, and the first and second support rods are used to support the column reinforcement cages. A certain number of horizontal beam stirrups are placed above the second support rods, and then a certain number of horizontal beam longitudinal bars are passed through the ends of the column reinforcement cages and the aforementioned horizontal beam stirrups. A portion of the longitudinal reinforcement bars of the crossbeams are fixedly connected to the upper edge of the column reinforcement cage, and this portion of the longitudinal reinforcement bars is fixedly connected to each crossbeam stirrup.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0044] The following is combined Figures 1 to 8 This invention describes the binding tool for precast wall reinforcement cages according to an embodiment of the present invention.

[0045] like Figures 1 to 8 As shown, an embodiment of the present invention provides a binding tool for a precast wall reinforcement cage, including a base frame and a transverse support assembly.

[0046] Specifically, the lateral support assembly includes a first support rod 2 and a second support rod 3 extending laterally. The first support rod 2 is fixedly connected to one end of the base frame, and at least two second support rods 3 are provided. The first support rod 2 and each of the second support rods 3 are distributed longitudinally at intervals, with a lateral reference. Figure 1 In the x-direction, the vertical direction is perpendicular to the horizontal direction, and the vertical reference is... Figure 1 y direction in .

[0047] A support base 9 is provided on the base frame and is fixedly connected to the base frame for connecting the end of the second support rod 3. The bottom of the support base 9 is provided with an opening, allowing the second support rod 3 to pass downwards. Each second support rod 3 is correspondingly provided with a support base 9 via a support shaft 1, and the end of the second support rod 3 is detachably connected to the support shaft 1. The support shaft 1 is detachably connected to the support base 9. By removing the support shaft 1 from the support base 9, the second support rod 3 can be taken out from the bottom opening of the support base 9.

[0048] When forming the precast wall reinforcement cage using the binding fixture provided in this embodiment of the invention, two pre-formed column reinforcement cages are placed on the base frame, and the column reinforcement cages are supported by the first support rod 2 and the second support rod 3. (See the two pre-formed column reinforcement cages for details.) Figure 2 The first reinforcing cage 14 and the second reinforcing cage 15 are included. A certain number of crossbeam stirrups are placed above the second support rod 3, and then a certain number of longitudinal crossbeam bars are passed through the ends of the column reinforcing cage and the aforementioned crossbeam stirrups. (See details for the crossbeam stirrups.) Figure 7 The third stirrup 16 in the middle, and the longitudinal reinforcement of the beam are shown in the figure. Figure 7 The third longitudinal reinforcement 17. A portion of the longitudinal reinforcement of the beam is fixedly connected to the upper edge of the column reinforcement cage, and this portion of the longitudinal reinforcement is fixedly connected to each beam stirrup. Then, the support shaft 1 and the second support rod 3 are removed from the base frame, forming an operating space below the longitudinal reinforcement of the beam. The remaining longitudinal reinforcement of the beam can be fixedly connected to the lower edge of the column reinforcement cage, and this portion of the longitudinal reinforcement of the beam is fixedly connected to each beam stirrup. Thus, the aforementioned longitudinal reinforcement of the beam and the beam stirrups are connected to form the beam reinforcement cage. See [reference needed for beam reinforcement cage]. Figure 2 The third reinforcing cage 18 is constructed, and the beam reinforcing cage is connected to the column reinforcing cage. Finally, according to the structural form of the precast wall reinforcing cage, the mesh 19 is fixed between the beam reinforcing cage and the column reinforcing cage.

[0049] With this configuration, when forming the precast wall reinforcement cage using the binding tool provided in the embodiment of the present invention, the longitudinal bars of each beam that makes up the beam reinforcement cage are first passed through the column reinforcement cage and then bound to form the beam reinforcement cage. Compared with the prior art, which passes the already formed beam reinforcement cage through the column reinforcement cage as a whole, this reduces the difficulty of inserting the longitudinal bars of the beam and helps to improve the binding efficiency.

[0050] It should be noted that when tying the precast wall reinforcement cage, the tying tool for the precast wall reinforcement cage should be selected according to the size of the precast wall reinforcement cage. If one tying tool for the precast wall reinforcement cage cannot meet the tying requirements, two tying tools for the precast wall reinforcement cage can be selected and distributed horizontally. The two tying tools can be used together to support the column reinforcement cage, the longitudinal reinforcement of the beam, and the stirrups of the beam.

[0051] For the fixed connection between the first support rod 2 and the base frame, the end of the first support rod 2 can be welded to the base frame, or the end of the first support rod 2 can be fixedly connected to the base frame with bolts.

[0052] In some embodiments, mounting holes are provided at the end of the second support rod 3 and on the support base 9, allowing the support shaft 1 to pass through. By passing the support shaft 1 through both the mounting holes on the second support rod 3 and the support base 9, the second support rod 3 and the support shaft 1 can be connected together. By removing the support shaft 1 from the second support rod 3 and the support base 9, the second support rod 3 can be moved downwards within the support base 9 until it is removed from the bottom opening of the support base 9.

[0053] In this embodiment, slots are provided at both ends of the second support rod 3, and the slots allow the support shaft 1 to extend into them. The end of the second support rod 3 is attached to the support shaft 1, and the slot is located on the side of the second support rod 3 closer to the support shaft 1, and the slot cooperates with the support shaft 1.

[0054] When it is necessary to remove the second support rod 3 from the base frame, the support shaft 1 is removed from the support seat 9, which allows the second support rod 3 to move downward within the support seat 9 until the second support rod 3 is removed from the bottom opening of the support seat 9.

[0055] In a further embodiment, the binding tool for the precast wall reinforcement cage also includes a power rod 4, which is rotatably connected to the base frame. The rotation axis is parallel to the plane containing the transverse and longitudinal directions. In this embodiment, the power rod 4 is arranged longitudinally relative to the rotation axis of the base frame.

[0056] A contact part 5 is provided at the first end of the power rod 4, and the second end of the power rod 4 is a free end. The rotational connection point between the power rod 4 and the base frame is located between the first end and the second end of the power rod 4. That is, the power rod 4 and the base frame are connected to form a lever mechanism.

[0057] The operator can apply force to the power rod 4 by holding the second end of the power rod 4, so that the power rod 4 rotates relative to the base frame. When the power rod 4 rotates relative to the base frame, the abutment part 5 located at the first end of the power rod 4 can abut against the second support rod 3. Through the interaction between the abutment part 5 and the second support rod 3, the second support rod 3 can be pushed upward away from the support shaft 1, and the support shaft 1 and the second support rod 3 can be disengaged, which can reduce the difficulty of disassembling the support shaft 1 from the support base 9.

[0058] A support plate is provided below the support base 9. When the second support rod 3 is installed on the base frame via the support shaft 1, there is a gap between the second support rod 3 and the support plate. After removing the support shaft 1, the end of the second support rod 3 can be placed on the support plate, and the support plate supports the second support rod 3. There is space between the support plate and the support base 9 for the second support rod 3 to pass through laterally, so that the second support rod 3 can be removed.

[0059] In this embodiment of the invention, the base frame includes a leg assembly and a third support rod 8.

[0060] The outrigger assembly includes a first outrigger 6 and a second outrigger 7, wherein the first outrigger 6 corresponds to the first support rod 2, and the second outrigger 7 corresponds to the second support rod 3. Both the first support shaft 1 and the second support shaft 1 extend vertically, and the vertical direction is perpendicular to both the horizontal and longitudinal directions. (Refer to...) Figure 1 The z-direction in the equation.

[0061] The third support rod 8 extends longitudinally, and one end of the third support rod 8 is fixedly connected to the first support leg 6. A support base 9 is disposed on the second support leg 7, and the second support leg 7 and the third support rod 8 are slidably engaged. Specifically, the second support leg 7 can slide relative to the third support rod 8 in the longitudinal direction. Through the relative sliding of the second support leg 7 and the third support rod 8, the position of each second support leg 7 relative to the first support leg 6 can be adjusted, thereby adjusting the relative position of each second support rod 3 to the first support rod 2.

[0062] The sliding engagement between the second leg 7 and the third support rod 8 can be achieved by providing a groove at the upper end of the second leg 7, which extends longitudinally through the upper end of the second leg 7. When the second leg 7 supports the third support rod 8, the third support rod 8 is positioned within the groove, allowing the second leg 7 to slide back and forth relative to the third support rod 8.

[0063] For precast wall reinforcement cages of different structural dimensions, the relative positions of the beam reinforcement cage and the column reinforcement cage are different. Therefore, the relative positions of the second support rod 3 and the first support rod 2 required during the binding process are also different. In this embodiment, the binding fixture for the precast wall reinforcement cage is configured with an adjustable position for the second support rod 3. This allows for the forming of precast wall reinforcement cages of different structural dimensions, improving the adaptability of the binding fixture provided in this embodiment.

[0064] Reference Figure 1 and Figure 2 The binding tool for the precast wall steel cage has one first leg 6 and three second legs 7 in the longitudinal direction. A connecting component is provided between one of the second legs 7 and the first leg 6, and a connecting component is provided between the other two second legs 7. The connecting component is used to fix the second leg 7 after adjusting its position, thereby improving the stability of the leg component.

[0065] Specifically, taking the connection assembly between the first leg 6 and the second leg 7 as an example, the connection assembly includes a connecting plate with two sets of connecting holes arranged longitudinally. One set of connecting holes is used to connect with the first leg 6, and the other set is used to connect with the second leg 7. Each set of connecting holes includes multiple connecting holes spaced apart longitudinally. By changing the connecting holes connected to the first leg 6 or the second leg 7, different distances between the first leg 6 and the second leg 7 can be accommodated.

[0066] In addition, the first leg 6 and the second leg 7 can also be configured as a height-adjustable structure.

[0067] In this embodiment, a plurality of first positioning grooves are provided on the first support rod 2 and the second support rod 3. The first positioning grooves extend longitudinally. The first positioning groove on the first support rod 2 penetrates the first support rod 2 longitudinally, and the first positioning groove on the second support rod 3 penetrates the second support rod 3 longitudinally. The plurality of first positioning grooves are distributed laterally at intervals.

[0068] The column reinforcement cage consists of multiple longitudinal bars and several stirrups. See [link to column longitudinal bars] for details. Figure 7 The second longitudinal reinforcement 20, and the column stirrups are shown in the figure. Figure 7 The second stirrup 10 is provided. The column stirrups are sleeved on the outside of each column longitudinal reinforcement, and each column stirrup is fixedly connected to each column longitudinal reinforcement. When the column reinforcement cage is placed on the binding fixture of the precast wall reinforcement cage, the column longitudinal reinforcement can be positioned in the first positioning groove on the first support rod 2 and the second support rod 3. Through the interaction between the first positioning groove and the column longitudinal reinforcement, the column reinforcement cage can be limited, ensuring the stability of the column reinforcement cage position on the binding fixture of the precast wall reinforcement cage.

[0069] The first positioning groove on the first support rod 2 and the first positioning groove on the second support rod 3 correspond one-to-one, so that the longitudinal reinforcement of the column is located in the first positioning groove and the second positioning groove 13 at the same time, which can ensure the perpendicularity of the longitudinal reinforcement of the column relative to the first support rod 2 and the second support rod 3.

[0070] When the crossbeam reinforcement cage is formed by binding, the crossbeam stirrups are placed on the second support rod 3, and the crossbeam stirrups can be positioned by the second positioning groove 13.

[0071] In a further embodiment, the lateral support assembly also includes a first positioning plate 21 and a second positioning plate 11.

[0072] A first positioning plate 21 is disposed on the first support rod 2, and the first positioning plate 21 is perpendicular to the longitudinal direction. The first positioning groove is provided on the first positioning plate 21, and the position of the first positioning plate 21 on the first support rod 2 is vertically adjustable, that is, the height of the first positioning groove is adjustable.

[0073] Accordingly, the second positioning plate 11 is disposed on the second support rod 3, and the second positioning plate 11 is perpendicular to the longitudinal direction. The first positioning groove is provided on the second positioning plate 11, and the position of the second positioning plate 11 on the second support rod 3 is vertically adjustable, that is, the height of the second positioning groove 13 is adjustable.

[0074] During the binding process to form the crossbeam reinforcement cage, it is necessary to ensure that the positions of the first positioning plate 21 and the second positioning plate 11 are such that the first positioning groove protrudes from the first support rod 2 and the second positioning groove 13 protrudes from the second support rod 3, so that the longitudinal reinforcement of the column can be located within the first positioning groove and the second positioning groove 13. When installing the mesh 19 on the column reinforcement cage and the bound crossbeam reinforcement cage, the position of the mesh 19 needs to be adjusted. To facilitate the adjustment of the position of the mesh 19, the positions of the first positioning plate 21 and the second positioning plate 11 can be adjusted in advance so that the first positioning groove is below the support surface of the first support rod 2 and the second positioning groove 13 is below the support surface of the second support rod 3.

[0075] In a specific embodiment, a strip-shaped hole can be provided on the first positioning plate 21, extending vertically. A threaded hole is provided on the first support rod 2, and a bolt is used to connect the bolt through the strip-shaped hole on the first positioning plate 21 and the threaded hole on the first support rod 2. Tightening the bolt causes the bolt nut to press the first positioning plate 21 tightly onto the first support rod 2. When it is necessary to adjust the height of the first positioning groove, the bolt can be loosened, allowing the first positioning plate 21 to slide up and down relative to the bolt.

[0076] The connection structure between the second positioning plate 11 and the second support rod 3 is the same as the connection structure between the first positioning plate 21 and the first support rod 2, and will not be described again here.

[0077] In this embodiment of the invention, a scale is provided on the first positioning plate 21, extending laterally. The scale allows for easy determination of the position of the column reinforcement cage on the binding fixture of the precast wall reinforcement cage.

[0078] In this embodiment, the transverse support assembly further includes a positioning baffle 12, which is disposed on the first support rod 2 and is perpendicular to the longitudinal direction. The positioning baffle 12 protrudes vertically from the support surface of the first support rod 2, and the vertical direction is perpendicular to both the transverse and longitudinal directions. When the column reinforcement cage is placed on the binding fixture of the precast wall reinforcement cage, the axis of the column reinforcement cage is along the longitudinal direction, and the longitudinal reinforcement bars of the column reinforcement cage are perpendicular to the positioning baffle 12. The ends of the longitudinal reinforcement bars are pressed against the positioning baffle 12. Through the interaction between the positioning baffle 12 and the longitudinal reinforcement bars, the column reinforcement cage can be limited.

[0079] In this embodiment of the invention, a plurality of second positioning grooves 13 are provided on the third support rod 8. The second positioning grooves 13 extend laterally and penetrate the third support rod 8 laterally. The plurality of second positioning grooves 13 are distributed longitudinally at intervals.

[0080] When placing the longitudinal reinforcement bars of the beam onto the binding tool of the precast wall reinforcement cage, the second positioning groove 13 can be used to limit the longitudinal reinforcement bars of the beam to ensure the stability of the longitudinal reinforcement bars of the beam.

[0081] On the other hand, the present invention also provides a method for binding precast wall reinforcement cages based on any of the above embodiments. The binding method for precast wall reinforcement cages described below can be referred to in correspondence with the binding fixtures for precast wall reinforcement cages described above.

[0082] For example Figure 6 Taking the precast wall reinforcement cage shown as an example, the precast wall reinforcement cage has a door area and a window area. The precast wall reinforcement cage includes three reinforcement cages and two L-shaped mesh panels 19. The three reinforcement cages are a first reinforcement cage 14, a second reinforcement cage 15, and a third reinforcement cage 18. The third reinforcement cage 18 is located at the end of the first reinforcement cage 14 and the second reinforcement cage 15, and the axial direction of the third reinforcement cage 18 is perpendicular to the axial direction of the first reinforcement cage 14 and the second reinforcement cage 15. The L-shaped mesh panels 19 are arranged within the space enclosed by the first reinforcement cage 14, the second reinforcement cage 15, and the third reinforcement cage 18. The L-shaped mesh panels 19, together with the second reinforcement cage 15 and the third reinforcement cage 18, form the window area, and the remaining area is the door area.

[0083] The method for tying precast wall reinforcement cages provided in this embodiment of the invention includes the following steps:

[0084] Step 110: Place the first and second reinforcing cages on the first and second support rods, with the axial direction of the first and second reinforcing cages along the longitudinal direction and the first and second reinforcing cages distributed along the transverse direction.

[0085] The first support rod 2 and the second support rod 3 simultaneously support the first reinforcing cage 14 and the second reinforcing cage 15. When the first reinforcing cage 14 and the second reinforcing cage 15 are placed on the first support rod 2 and the second support rod 3, the first longitudinal reinforcement of the first reinforcing cage 14 and the second longitudinal reinforcement 20 of the second reinforcing cage 15 are located in the first positioning grooves on the first support rod 2 and the second support rod 3, ensuring that the first reinforcing cage 14 and the second reinforcing cage 15 are perpendicular to the first support rod 2.

[0086] At the same time, the ends of the first steel cage 14 and the second steel cage 15 need to be pressed against the positioning baffle 12 to position the first steel cage 14 and the second steel cage 15.

[0087] When placing the first steel cage 14 and the second steel cage 15, the positions of the first steel cage 14 and the second steel cage 15 can be determined according to the scale on the first support rod 2 to ensure the spacing between the first steel cage 14 and the second steel cage 15.

[0088] Step 120: Place the target number of third stirrups above the second support rod, with each third stirrup distributed laterally.

[0089] When placing the third stirrup 16, the third stirrup 16 can be positioned in the first positioning groove on the second support rod 3, and the third stirrup 16 can be positioned by the second positioning groove 13, which makes it convenient to determine the position of each third stirrup 16.

[0090] Step 130: Make the target number of third longitudinal bars pass through the first steel cage, each of the third stirrups and the second steel cage in sequence.

[0091] Each of the third longitudinal bars 17 is independent of each other, and each of the third longitudinal bars 17 can be sequentially passed through the first steel cage 14, each of the third stirrups 16 and the second steel cage 15.

[0092] Step 140: Fix both ends of a portion of the third longitudinal reinforcement to the upper edge of the first steel cage and the upper edge of the second steel cage, respectively, and fix them to the third stirrup.

[0093] The first longitudinal reinforcement bar 14 is located at the upper vertical edge of the first reinforcing cage 14 when it is placed longitudinally on the binding fixture for the precast wall reinforcing cage. The second longitudinal reinforcement bar 20 is located at the upper vertical edge of the second reinforcing cage 15 when it is placed longitudinally on the binding fixture for the precast wall reinforcing cage.

[0094] The third stirrup 16 is supported on the second support rod 3. First, the two ends of a portion of the third longitudinal bar 17 are tied and fixed to the first longitudinal bar 20 of the upper layer of the first steel cage 14 and the second longitudinal bar 20 of the upper layer of the second steel cage 15 using tie wire. Then, the portion of the third longitudinal bar 17 is tied and fixed together with each of the third stirrups 16 using tie wire.

[0095] When tying the third longitudinal bar 17 and the third stirrup 16, do not tie and fix the stirrups at the locations where components such as exhaust pipes and air conditioning pipes need to be embedded.

[0096] Step 150: Remove the support shaft and the second support rod located below the third longitudinal reinforcement from the base frame.

[0097] After completing step 140, each of the third longitudinal bars 17 is suspended between the first steel cage 14 and the second steel cage 15, and each of the third stirrups 16 is suspended on each of the third longitudinal bars 17. At this time, removing the support shaft 1 and the second support rod 3 located below the third longitudinal bars 17 will not affect the position of the third stirrups 16 or the already tied third longitudinal bars 17, and will also create a larger operating space below the third longitudinal bars 17, facilitating operation.

[0098] Step 160: Fix the two ends of the remaining third longitudinal bars to the lower edge of the first steel cage and the lower edge of the second steel cage respectively, and fix them to the third stirrups. The third longitudinal bars and the third stirrups are connected to form the third steel cage.

[0099] The lower vertical edge of the first reinforcing cage 14 forms the lower first longitudinal reinforcement bar when the first reinforcing cage 14 is placed longitudinally on the binding fixture for the precast wall reinforcing cage. The lower vertical edge of the second reinforcing cage 15 forms the lower second longitudinal reinforcement bar 20 when the second reinforcing cage 15 is placed longitudinally on the binding fixture for the precast wall reinforcing cage.

[0100] After removing the support shaft 1 and the second support rod 3, use tie wire to tie and fix the two ends of the remaining third longitudinal reinforcement 17 to the first longitudinal reinforcement of the lower layer of the first steel cage 14 and the second longitudinal reinforcement 20 of the lower layer of the second steel cage 15 respectively. Then use tie wire to tie and fix this part of the third longitudinal reinforcement 17 to each of the third stirrups 16 respectively.

[0101] Thus, the third longitudinal reinforcement 17 and the third stirrup 16 are tied and fixed, forming the third steel cage 18 which is connected to the first steel cage 14 and the second steel cage 15.

[0102] Step 170: Connect a pair of mesh panels to the first, second, and third reinforcing cages, and reinforce the mesh panels.

[0103] After completing step 160, install the mesh 19 on the first steel cage 14, the second steel cage 15 and the third steel cage 18 according to the position of the mesh 19, and then reinforce the mesh 19.

[0104] The derivation process of the beneficial effects of the precast wall reinforcement cage binding method in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the precast wall reinforcement cage binding tool described above, so it will not be repeated here.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
