Abstract

This invention discloses an auxiliary installation device for the reinforcing bars of a cast-in-place bridge substructure beam, relating to the field of reinforcing bar installation in bridge substructure beams. It solves the problem of difficulty in supplementing the binding of reinforcing bars during acceptance testing of existing steel reinforcement frames. The device includes a handle with an installation head fixedly mounted on its upper end. The installation head is U-shaped, and a limiting cavity is formed between one end of the installation head and the handle. The user can insert the installation head through the gap between the reinforcing bars in the cage using the handle, placing it on the connection of the reinforcing bars to be bound. A linkage mechanism allows the binding wire inside the sliding arc rod to be passed around the connection and transferred to the other end of the installation head. Simultaneously, the binding wire is clamped by a clamping component. The binding wire is then wrapped around the connection of the reinforcing bars to be bound. Twisting the installation head with the handle tightens the binding wire, quickly completing the supplementary binding of the reinforcing bars at this location.

Description

Technical Field

[0001] This invention relates to the field of reinforcement installation for bridge substructure beams, specifically to an auxiliary installation device for reinforcement installation of cast-in-place bridge substructure beams. Background Technology

[0002] During the construction and pouring of concrete for bridge piers, a substructure beam is installed between the two piers. The substructure beam strengthens the overall rigidity of the piers. During construction, the substructure beam reinforcement is tied between the steel reinforcement frames of the two piers. After tying, stirrups are placed around the substructure beam reinforcement, and then the stirrups are tied. Finally, formwork is set around the pier reinforcement and the substructure beam reinforcement, and then concrete is poured. The substructure beam is installed at the bottom of the pier.

[0003] During the binding of the substructure beam and pier column reinforcement, as well as the binding of the stirrups, the reinforcement bars are arranged in an orderly and dense manner. During binding, workers use hooks to twist and bind the steel wires. Due to the large amount of binding work, it is easy for some structural parts to be missed. After the reinforcement frame is bound, an inspection is required. If any missed binding is found, it needs to be re-bound. At this time, because the reinforcement bars are tightly fixed and intertwined, the binding space is very narrow, and the hooks are short, it is very difficult to bind the missed binding points of the substructure beam and pier column reinforcement, especially when supplementing the binding of the bottom reinforcement. We propose an auxiliary installation device for the reinforcement of the substructure beam of cast-in-place bridges. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary installation device for the reinforcing bars of the substructure beam of a cast-in-place bridge that can supplement the binding of reinforcing bar connections in a narrow space between reinforcing bars, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary installation device for reinforcing bars of a cast-in-place bridge substructure beam, comprising a handle, an installation head fixedly installed at the upper end of the handle, the installation head being U-shaped, a limiting cavity being formed between one side end of the installation head and the handle, and a cavity being formed at the other end of the installation head; a wire conveying assembly, which allows the wire to be passed around the reinforcing bars, is installed inside the limiting cavity, and an anti-detachment component is installed on the side wall of the wire conveying assembly; a clamping assembly, which clamps the wire passed by the wire conveying assembly, is installed inside the cavity, and the U-shaped installation head can be used to connect the reinforcing bars that need to be tied.

[0006] Preferably, the wire conveying assembly includes a sliding arc rod that is slidably embedded inside the limiting cavity, and a wire cavity is formed on the inner side of the sliding arc rod. A binding wire is movably embedded inside the wire cavity. A clamping member is installed at the upper end of the wire cavity, and a linkage member is installed between the sliding arc rod and the handle. Under the push of the linkage member, the sliding arc rod can extend towards the cavity until it touches it.

[0007] Preferably, the clamping component includes two sets of limiting seats fixedly installed on the top of the sliding arc rod, and each of the two sets of limiting seats has a slider slidably embedded inside. A rubber wheel is rotatably installed between the two opposing sets of sliders via a connecting shaft, and the two sets of rubber wheels are symmetrically distributed around the upper end of the wire cavity. A spring is fixedly installed between the end of the slider away from the wire cavity and the limiting seat. When the binding wire is folded and bent and then embedded into the wire cavity, the rubber wheel can clamp the binding wire to prevent the sliding arc rod from falling off during the conveying of the binding wire.

[0008] Preferably, the linkage includes a top plate fixedly installed inside the handle, and a spring is fixedly installed at the lower end of the top plate. A push rod is fixedly connected to the lower end of the spring, and the push rod is slidably embedded inside the handle. A connecting arm is movably installed between the push rod and the sliding arc rod through a connecting post, and the connecting post is slidably engaged with the handle. A lever is fixedly installed at the bottom front end of the push rod. By pushing the push rod with the lever, the connecting arm can extend the sliding arc rod from inside the limiting cavity.

[0009] Preferably, the clamping assembly includes a limiting rod fixedly installed inside the cavity, and two sets of staggered diagonal rods are movably sleeved on the outer surface of the limiting rod. A clamping plate is fixedly installed at the upper end of each set of diagonal rods, and a spring is fixedly installed between the two sets of diagonal rods. A sliding column is fixedly embedded at the lower end of each set of diagonal rods, and a U-shaped groove plate is movably sleeved at both ends of the sliding column. Several sets of meshing teeth are fixedly installed on the opposing sides of each set of clamping plates, and the two sets of meshing teeth mesh with each other. An actuating element is installed between the U-shaped groove plate and the handle. Actuating the actuating element can open the two sets of clamping plates and effectively clamp the end of the binding wire.

[0010] Preferably, the first actuating element includes a steel cable groove formed inside the mounting head and the handle, and the steel cable groove is interconnected with the cavity. A second steel cable is slidably embedded in the inner side of the steel cable groove. A push block is fixedly installed at the bottom of the second steel cable, and the push block is slidably embedded in the inner side of the handle. A second spring is fixedly installed at the upper end of the push block. The upper end of the second steel cable is fixedly connected to the U-shaped groove plate through a connecting plate. When the spring is compressed by the push block, the second steel cable is in a relaxed state. At this time, under the push of the third spring, the two sets of clamps can be unfolded.

[0011] Preferably, the anti-detachment component includes a stop block slidably embedded inside the sliding arc rod, with the bottom of the stop block embedded inside the wire cavity. A spring five is fixedly installed between the end of the stop block away from the wire cavity and the sliding arc rod. An angled block is fitted to the outer side of the mounting head, and a connecting rod is fixedly installed between the angled block and the stop block. The connecting rod slides through the sliding arc rod. A roller is movably engaged at the open corner of the angled block, and a rocker arm is rotatably sleeved at both ends of the roller. A bracket is slidably embedded between the two sets of rocker arms, and the bracket is fixedly connected to the mounting head. A trigger is installed at the end of the rocker arm away from the roller. During the process of the bent part of the binding wire extending into the wire cavity, the bent part can first push the stop block, which can then move the stop block upward. After the bent part of the binding wire passes the stop block, the stop block rebounds under the action of the spring five, and can then be locked between the bent binding wires.

[0012] Preferably, the second actuating element includes a limiting sleeve fixedly installed on the left side wall of the handle, and a steel cable is movably embedded inside the limiting sleeve. A lever block is fixedly installed at the bottom of the steel cable, and the upper end of the steel cable extends to the outer wall of the mounting head. A locking block is movably sleeved on the outer side of the steel cable, and the locking block is fixedly connected to the mounting head. The upper end of the steel cable is hinged to two sets of rocker arms through the mounting block. A fixing ring is fixedly sleeved on the outer side of the steel cable, and a spring four is fixedly installed between the fixing ring and the locking block. A protective sleeve is movably sleeved on the outer side of the spring four and the corner block, and the protective sleeve is fixedly connected to the mounting head. When the steel cable is pulled, its rocker arm drives the corner block to lift, which allows the stop block to retract into the interior of the sliding arc rod and no longer limit the bending point of the binding wire.

[0013] Preferably, the distance between the two sets of rubber wheels is smaller than the diameter of the binding wire, so as to ensure that the two sets of rubber wheels can effectively clamp the binding wire.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, the user can insert the installation head through the gap between the reinforcing cages using the handle, so that the installation head is placed on the connection of the reinforcing bars that need to be tied. The binding wire inside the sliding arc rod can be passed around the connection of the reinforcing bars to the other end of the installation head through the linkage component. At the same time, the binding wire is clamped by the clamping component. At this time, the binding wire is wrapped around the connection of the reinforcing bars that need to be tied. Then, by twisting the installation head with the handle, the binding wire can be tightened, and the supplementary binding of the reinforcing bars at this point can be quickly completed.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figure 1 The diagram shows an auxiliary installation device for the reinforcing bars of a cast-in-place bridge substructure beam. It includes a handle 1, with an installation head 2 fixedly mounted on the upper end of the handle 1. The installation head 2 is U-shaped, with a limiting cavity 3 between one side of the installation head 2 and the handle 1, and a cavity 4 at the other end of the installation head 2. A wire conveying assembly 5, which allows wire to be passed around the reinforcing bars, is installed inside the limiting cavity 3, and an anti-detachment assembly 9 is installed on the side wall of the wire conveying assembly 5. A clamping assembly 7, which clamps the wire passed by the wire conveying assembly 5, is installed inside the cavity 4. The U-shaped installation head 2 can be used to connect the reinforcing bars that need to be tied.

[0028] Please see Figure 2 , Figure 4 and Figure 8 The wire conveying assembly 5 shown in the figure includes a sliding arc rod 12 that is slidably embedded in the limiting cavity 3, and a wire cavity 13 is opened on the inner side of the sliding arc rod 12. A binding wire 46 is movably embedded in the wire cavity 13. A clamping member 6 is installed at the upper end of the wire cavity 13, and a linkage member 11 is installed between the sliding arc rod 12 and the handle 1. Under the push of the linkage member 11, the sliding arc rod 12 can extend towards the cavity 4 until it touches it.

[0029] Please see Figure 2 The linkage 11 shown in the figure includes a top plate 14 fixedly installed inside the handle 1, and a spring 16 fixedly installed at the lower end of the top plate 14. A push rod 17 is fixedly connected to the lower end of the spring 16, and the push rod 17 is slidably embedded inside the handle 1. A connecting arm 15 is movably installed between the push rod 17 and the sliding arc rod 12 through a connecting post, and the connecting post and the handle 1 are slidably engaged. A lever 18 is fixedly installed at the bottom front end of the push rod 17. By pushing the push rod 17 through the lever 18, the connecting arm 15 can extend the sliding arc rod 12 out from inside the limiting cavity 3.

[0030] Please see Figure 3 and Figure 6The clamping assembly 7 shown in the figure includes a limiting rod 26 fixedly installed inside the cavity 4, and two sets of staggered diagonal rods 27 are movably sleeved on the outer surface of the limiting rod 26. The upper ends of the two sets of diagonal rods 27 are fixedly installed with clamping plates 28, and springs 39 are fixedly installed between the two sets of diagonal rods 27. The lower ends of the two sets of diagonal rods 27 are fixedly embedded with sliding columns 30, and U-shaped groove plates 31 are movably sleeved at both ends of the sliding columns 30. Several sets of meshing teeth 47 are fixedly installed on the opposing sides of the two sets of clamping plates 28, and the two sets of meshing teeth 47 mesh with each other. A trigger 8 is installed between the U-shaped groove plate 31 and the handle 1. By triggering the trigger 8, the two sets of clamping plates 28 can be opened, and the ends of the binding wire 46 can be effectively clamped.

[0031] Please see Figure 2 and Figure 3 The actuating element 8 shown in the figure includes a steel cable groove 22 opened inside the mounting head 2 and the handle 1, and the steel cable groove 22 is connected to the cavity 4. A steel cable 23 is slidably embedded in the inner side of the steel cable groove 22. A push block 25 is fixedly installed at the bottom of the steel cable 23, and the push block 25 is slidably embedded in the inner side of the handle 1. A spring 24 is fixedly installed at the upper end of the push block 25. The upper end of the steel cable 23 is fixedly connected to the U-shaped groove plate 31 through a connecting plate. When the spring 24 is compressed by the push block 25, the steel cable 23 is in a relaxed state. At this time, under the push of the spring 3 29, the two sets of clamps 28 can be unfolded.

[0032] The working principle of supplementing the binding of steel bars in narrow steel bar gaps is as follows: When supplementing the binding of some steel bar connections inside the steel cage, the user first folds and bends the binding wire 46, inserts the curved end of the binding wire 46 into the wire cavity 13, and continues to extend the binding wire 46. During the extension process, the bent part of the binding wire 46 will touch the anti-detachment component 9. Under the action of the anti-detachment component 9, the binding wire 46 cannot be pulled out directly from the inside of the wire cavity 13, so that the binding wire 46 continues to extend into the inside of the wire cavity 13, and the end of the binding wire 46 will not exceed the upper port of the limiting cavity 3.

[0033] Next, the user inserts the installation head 2 into the interior of the rebar cage using handle 1, and places the installation head 2 on the front end of the rebar connection to be tied. At this point, the user can push the push block 18, and its push rod 17 will push the sliding arc rod 12 out of the limiting cavity 3 through the connecting arm 15. When the front end of the sliding arc rod 12 is about to contact the clamping plate 28, the user compresses the spring 24 using push block 25, so that the steel cable 23 is in a relaxed state. At this time, the two sets of staggered diagonal rods 27 can unfold with the clamping plate 28 under the action of the spring 39 and the sliding column 30 and the U-shaped groove plate 31. After fully unfolding, the user continues to push the sliding arc rod 12, so that the sliding arc rod... 12 moves the front end of the binding wire 46 inside to between the two sets of clamps 28. At this time, the user first resets the push block 25 and presses the push block 25 down. The purpose is to make the biting teeth 47 effectively clamp and fix the front end of the binding wire 46. After that, the lever 18 can be released. Under the action of the spring 16, the sliding arc rod 12 is quickly reset. At this time, the binding wire 46 inside the wire cavity 13 surrounds the steel bar connection that needs to be bound. The user pulls the installation head 2 through the handle 1 so that the binding wire 46 extends out of the wire cavity 13 as much as possible. Since the anti-drop component 9 is set at the front end of the sliding arc rod 12, most of the binding wire 46 can extend out of the wire cavity 13.

[0034] At this point, the mounting head 2 can be rotated by the handle 1 to make the binding wire 46 wrap around the rebar connection. After wrapping, the binding wire 46 can be limited by the trigger 10 and the secondary push block 25. In this way, the additional binding of rebar can be completed in the narrow rebar cage gap.

[0035] Example 2

[0036] Please see Figure 5 and Figure 7 This embodiment further illustrates Example 1. The anti-fall-off component 9 includes a stop block 39 that is slidably embedded inside the sliding arc rod 12. The bottom of the stop block 39 is embedded inside the wire cavity 13. A spring 40 is fixedly installed between the end of the stop block 39 away from the wire cavity 13 and the sliding arc rod 12. An angled block 38 is fitted to the outside of the mounting head 2. A connecting rod is fixedly installed between the angled block 38 and the stop block 39. The connecting rod slides through the sliding arc rod 12. A roller 37 is movably engaged at the open corner of the angled block 38. Both the front and rear ends of the roller 37 are rotatably sleeved with a rocker arm 36. A bracket 35 is slidably embedded between the two sets of rocker arms 36. The bracket 35 is fixedly connected to the mounting head 2. An actuating element 10 is installed at the end of the rocker arm 36 away from the roller 37.

[0037] Please see Figure 2 , Figure 4and Figure 5 The second trigger 10 in the figure includes a limiting sleeve 19 fixedly installed on the left side wall of the handle 1, and a steel cable 20 is movably embedded inside the limiting sleeve 19. A lever 21 is fixedly installed at the bottom of the steel cable 20. The upper end of the steel cable 20 extends to the outer wall of the mounting head 2. A snap-fit ​​block 33 is movably sleeved on the outside of the steel cable 20, and the snap-fit ​​block 33 is fixedly connected to the mounting head 2. The upper end of the steel cable 20 is hinged to two sets of rocker arms 36 through the mounting block. A fixing ring 45 is fixedly sleeved on the outside of the steel cable 20, and a spring 34 is fixedly installed between the fixing ring 45 and the snap-fit ​​block 33. A protective sleeve 32 is movably sleeved on the outside of the spring 34 and the corner block 38, and the protective sleeve 32 is fixedly connected to the mounting head 2.

[0038] The working principle of limiting the bending part of the binding wire 46 is as follows: When the bending part of the binding wire 46 extends into the wire cavity 13, the bending part can first push the stop block 39, which can then move the stop block 39 upward. After the bending part of the binding wire 46 passes the stop block 39, the stop block 39 rebounds under the action of the spring 40, and can then be locked between the bent binding wires 46, thus limiting the bending part of the binding wire 46. When it is necessary to cancel the limit, simply pull the steel cable 20 by the lever 21, and the lever 36 drives the angle block 38 to lift, which can then retract the stop block 39 into the sliding arc rod 12, no longer limiting the bending part of the binding wire 46.

[0039] Example 3

[0040] Please see Figure 3 The embodiment further describes other embodiments. The clamping member 6 includes two sets of limiting seats 41 fixedly installed on the top of the sliding arc rod 12. The two sets of limiting seats 41 are each slidably embedded with a slider 43. The two sets of opposing sliders 43 are rotatably installed with a rubber wheel 42 through a connecting shaft. The two sets of rubber wheels 42 are symmetrically distributed with respect to the upper port of the wire cavity 13. A spring 44 is fixedly installed between the end of the slider 43 away from the wire cavity 13 and the limiting seat 41.

[0041] Please see Figure 7 and Figure 8 The distance between the two sets of rubber wheels 42 in the diagram is smaller than the diameter of the binding wire 46, so as to ensure that the two sets of rubber wheels 42 can effectively clamp the binding wire 46.

[0042] In this embodiment: when the binding wire 46 is folded and bent and then embedded into the wire cavity 13, the rubber wheel 42 can clamp the binding wire 46 to prevent the sliding arc rod 12 from falling off during the conveying of the binding wire 46.
