Description
Technical Field
[0001] The present application relates to the technical field of building construction, and particularly to an auxiliary bracket for binding beam reinforcement bars. Background Art
[0002] Currently, in building construction, the binding of beam reinforcement bars is a key step to ensure the quality of beam structures.
[0003] When binding beam reinforcement bars, a rack is usually used to lift the beam reinforcement bars, and then the positions of the intersections of the main reinforcement bars and the hoop reinforcement bars are bound.
[0004] The above prior art solutions have the following defects: The existing rack only lifts the steel bars, and the relative positional relationship between the beam reinforcement bars and the hoop reinforcement bars cannot be determined. When binding the main reinforcement bars and the hoop reinforcement bars of the beam reinforcement bars, adjustment needs to be carried out while binding, and workers need to frequently move the positions of the main reinforcement bars, resulting in low work efficiency. Content of the Utility Model
[0005] In order to improve the work efficiency of workers when binding beam reinforcement bars, the present application provides an auxiliary bracket for binding beam reinforcement bars.
[0006] The above technical objectives of the present application are achieved through the following technical solutions:
[0007] An auxiliary bracket for binding beam reinforcement bars, the auxiliary bracket is arranged inside a beam cage, and the auxiliary bracket includes a base and a lifting device. One side of the base is in contact with the working surface, and a plurality of lifting devices are fixedly connected to the side of the base away from the working surface. One lifting device is correspondingly arranged in each unit formed by the main reinforcement bars and the hoop reinforcement bars of the beam cage; each lifting device includes a support rod and a cross bar. One end of the support rod is fixedly connected to the base, and the other end of the support rod is fixedly connected to the cross bar. The cross bar is used to lift the main reinforcement bars on both sides of the support rod; a first limiting device is fixedly connected to the cross bar. The first limiting device includes a first gear, a first rack and a second rack. The first gear is fixedly connected to the cross bar. The first rack and the second rack are respectively arranged on both sides of the first gear. The first rack and the second rack are both meshed with the first gear. The ends of the first rack and the second rack facing away from each other are both in contact with the main reinforcement bars.
[0008] By adopting the above solution, first, a base is set up, and then several lifting devices are arranged on the base. When using the lifting devices to lift the beam cage, the cross bar lifts the main reinforcement bars, causing the main reinforcement bars to abut against the hoop stirrups in the vertical direction. Since a first gear is fixedly connected to the cross bar, when the cross bar abuts against the main reinforcement bars, the first gear is rotated, and the first gear drives the first rack and the second rack to move in opposite directions, so that the mutually remote ends of the first rack and the second rack both abut against the main reinforcement bars, causing the main reinforcement bars to abut against the hoop stirrups in the horizontal direction. Through the above arrangement, the places where the main reinforcement bars and the hoop stirrups need to be tied are completely abutted. When tying the main reinforcement bars and the hoop stirrups, direct operation can be carried out, and there is no need to manually limit the positions between the main reinforcement bars and the hoop stirrups, achieving the effect of improving the working efficiency of workers during beam reinforcement tying.
[0009] Further, a second limiting device is arranged on each of the support rods. Each second limiting device includes a sleeve, an inner rod, and a dial plate. The sleeve is sleeved on the support rod, and an inner rod is inserted at each of the two ends of the sleeve. The mutually remote ends of the two inner rods both abut against the main reinforcement bars. A sliding groove is formed in the sleeve, and a dial plate is fixedly provided on each inner rod. The end of each dial plate away from the inner rod passes through the sliding groove.
[0010] By adopting the above solution, since the four corners of the hoop stirrups need to be tied to the main reinforcement bars, the cross bar and the first limiting structure are used to limit the positions of the two upper corners of the hoop stirrups and the main reinforcement bars. Due to the action of gravity, the main reinforcement bars located below abut against the bottom of the hoop stirrups in the vertical direction. Then, a second limiting structure is provided. The second limiting structure is used to control the positional relationship between the main reinforcement bars located below and the hoop stirrups in the horizontal direction. The two dial plates are respectively toggled, and the two dial plates drive the two inner rods to move in opposite directions until the mutually remote ends of the two inner rods both abut against the main reinforcement bars, causing the end of the main reinforcement bar away from the inner rod to abut against the hoop stirrups, facilitating the tying of the intersection points between the main reinforcement bars and the hoop stirrups.
[0011] Further, lifting devices are arranged on both sides of the support rod. Each lifting device is located between the base and the sleeve. Each lifting device includes a fixed rod, a lifting rod, and a setscrew. One end of the fixed rod is fixedly connected to the base, and a lifting groove is formed at the end of the fixed rod away from the lifting rod. One end of the lifting rod is inserted into the lifting groove, and the lifting rod is slidably connected to the lifting groove. The other end of the lifting rod is fixedly connected to the sleeve, and the setscrew passes through the sleeve and abuts against the inner rod.
[0012] By adopting the above scheme, a lifting structure is set on the base, and the lifting structure is used to control the position relationship between the second limiting structure and the support rod, and push the lifting rod, and the lifting rod slides up and down along the lifting groove. Since the lifting rod is fixedly connected to the sleeve, the displacement of the lifting rod along the lifting groove drives the sleeve to move up and down along the support rod until the position of the sleeve corresponds to the position of the main reinforcement, and the top screw is rotated. The top screw passes through the side wall of the lifting groove and abuts against the lifting rod. By locking the position relationship between the lifting rod and the lifting groove, the position relationship between the second limiting structure and the main reinforcement is locked.
[0013] Furthermore, a sliding structure is provided between each of the lifting devices and the base, the sliding structure comprising a dovetail groove and a dovetail bar, the base is provided with a dovetail groove, the support rod is correspondingly fixedly connected to the dovetail bar, and the dovetail groove is slidably connected to the dovetail bar.
[0014] By adopting the above scheme, a dovetail groove is opened on the base, and a dovetail bar is fixedly connected to one end of each support rod fixedly connected to the base, so that the dovetail groove and the dovetail bar are slidably connected, and then several support rods are slidably connected to the base. By controlling the relative sliding between the dovetail groove and the dovetail bar, the positional relationship between the entire lifting device and the base can be controlled.
[0015] Furthermore, a locking structure is also provided on the support rod, and the locking structure includes a ring, a locking rod and a sealing ring. The ring is sleeved outside the support rod, and the ring is slidably connected to the support rod. A plurality of locking rods are fixedly connected to the circumferential side of the ring, and the sides of the plurality of locking rods away from the ring are all abutted against the base. The sealing ring is sleeved outside the support rod, and the sealing ring is located above the ring. The sealing ring is threadedly connected to the support rod.
[0016] By adopting the above scheme, the locking structure is used to lock the lifting device and the base after the relative position between the lifting device and the base is determined, and the sliding ring is used. Since a plurality of locking rods are also provided on the ring, when the ring moves along the support rod, when one end of the plurality of locking rods away from the ring abuts against the base, the plurality of locking rods disperse the force exerted on the support rod, making the support rod more stable, and then the blocking ring is rotated until the blocking ring and the ring are completely abutted, and the blocking ring and the ring abut, further making the locking rod abut against the base, thereby completing the locking of the relative position between the lifting device and the base.
[0017] Furthermore, a pushing device is arranged between the two paddles, and the pushing device includes a second gear, a third rack and a fourth rack. The second gear is fixedly connected to the sleeve, and the third rack and the fourth rack are respectively arranged on both sides of the second gear. The third rack and the fourth rack are both meshed with the second gear. The ends of the third rack and the fourth rack facing away from each other are respectively abutted against the two paddles, and the third rack and the fourth rack are both used to limit the paddle.
[0018] By adopting the above solution, a pushing device is arranged between two dial plates on the sleeve. By rotating the first gear, the rotation of the first gear can drive the third rack and the fourth rack to move in two opposite directions. The third rack and the fourth rack can drive the two dial plates to move in opposite directions, and the two dial plates drive the two inner rods to move in opposite directions along the sleeve until both inner rods are in contact with the main reinforcement, thereby pushing the two main reinforcements into contact with the circular stirrups.
[0019] Furthermore, a U-shaped plate is fixedly connected to each end of each inner rod away from each other, and the U-shaped groove of the U-shaped plate is used for clamping with the main reinforcement.
[0020] By adopting the above solution, a U-shaped plate is fixedly connected to each end of the two inner rods away from each other. When the inner rod abuts against the main reinforcement, the main reinforcement is stuck in the U-shaped groove, restricting the relative positional relationship between the main reinforcement and the inner rod and preventing the relative positional relationship between the main reinforcement and the inner rod from changing.
[0021] Furthermore, fixed plates are fixedly connected to the ends of the first rack and the second rack that are in contact with the main reinforcement, and the fixed plates are used for limiting the main reinforcement.
[0022] By adopting the above solution, fixed plates are fixedly connected to the ends of the first rack and the second rack that are in contact with the main reinforcement. An L-shaped groove is formed between the fixed plate and the first rack. When abutting against the main reinforcement, the main reinforcement is stuck in the L-shaped groove, and the L-shaped groove restricts the relative positional relationship between the main reinforcement and the first rack or the second rack.
[0023] In summary, the present application has the following technical effects:
[0024] 1. By providing an auxiliary support, first a base is set, and then several lifting devices are arranged on the base. When using the lifting devices to lift the beam cage, the cross bar lifts the main reinforcement, so that the main reinforcement abuts against the circular stirrups in the vertical direction. Since the first gear is fixedly connected to the cross bar, when the cross bar abuts against the main reinforcement, the first gear is rotated, and the first gear drives the first rack and the second rack to move in opposite directions, so that the ends of the first rack and the second rack away from each other are both in contact with the main reinforcement, making the main reinforcement abut against the circular stirrups in the horizontal direction. Through the above settings, the places where the main reinforcement and the circular stirrups need to be tied are completely in contact. When tying the main reinforcement and the circular stirrups, direct operation can be carried out without manually limiting the position between the main reinforcement and the circular stirrups, achieving the effect of improving the working efficiency of workers when tying beam reinforcement;
[0025] 2. By setting a second limiting device, since the four corners of the hoop reinforcement need to be tied with the main reinforcement, the cross bar and the first limiting structure are used to limit the position of the two corners of the hoop reinforcement at the top and the main reinforcement. Due to the effect of gravity, the main reinforcement at the bottom is in contact with the bottom of the hoop reinforcement in the vertical direction. A second limiting structure is set, and the second limiting structure is used to control the horizontal position relationship between the main reinforcement at the bottom and the hoop reinforcement. The two dial plates are respectively moved, and the two dial plates drive the two inner rods to move away from each other until the ends of the two inner rods away from each other are in contact with the main reinforcement, so that the end of the main reinforcement away from the inner rod is in contact with the hoop reinforcement, which is convenient for binding the intersection between the main reinforcement and the hoop reinforcement;
[0026] 3. A lifting device is provided and a lifting structure is provided on the base. The lifting structure is used to control the positional relationship between the second limiting structure and the support rod. The lifting rod is pushed and the lifting rod slides up and down in the lifting slot. Since the lifting rod is fixedly connected to the sleeve, the displacement of the lifting rod along the lifting slot drives the sleeve to move up and down along the support rod until the position of the sleeve corresponds to the position of the main reinforcement. The top screw is rotated and the top screw passes through the side wall of the lifting slot and abuts against the lifting rod. The positional relationship between the lifting rod and the lifting slot is locked, thereby locking the positional relationship between the second limiting structure and the main reinforcement.

In this embodiment, a plurality of lifting devices 4 are provided, and one lifting device 4 is provided in each unit formed by the abutment of each ring stirrup 2 and the main reinforcement bar 1. Each lifting device 4 includes a support rod 41 and a cross bar 42. One end of the support rod 41 is fixedly connected to the base 3, and the other end of the support rod 41 is fixedly connected to the cross bar 42. Both ends of the cross bar 42 are used to lift the main reinforcement bars 1 on both sides of the support rod 41, so that the main reinforcement bars 1 abut against the ring stirrups 2, facilitating the operator to bind the intersection points of the main reinforcement bars 1 and the ring stirrups 2.
[0033] Refer to Figure 1 - Figure 3 , a first limiting device 5 is provided on each cross bar 42. Each first limiting device 5 includes a first gear 51, a first rack 52 and a second rack 53. The first gear 51 is fixedly connected to the cross bar 42. The first rack 52 and the second rack 53 are respectively located on both sides of the first gear 51. The movement directions between the first rack 52 and the second rack 53 are relatively away from each other. Both the first rack 52 and the second rack 53 are engaged with the first gear 51. The mutually departing ends of the first rack 52 and the second rack 53 are both used to abut against the main reinforcement bar 1; rotating the first gear 51, the rotation of the first gear 51 drives the first rack 52 and the second rack 53 to move in the mutually departing directions. The first rack 52 and the second rack 53 can push the main reinforcement bar 1 in the direction close to the ring stirrup 2 until the main reinforcement bar 1 abuts against the ring stirrup 2; fixed plates 20 are fixedly connected to the mutually departing ends of the first rack 52 and the second rack 53. An L-shaped groove is formed between the fixed plate 20 and one end of each of the first rack 52 and the second rack 53. When using the first rack 52 and the second rack 53 to abut against the main reinforcement bars 1 on both sides of the support rod 41, the main reinforcement bar 1 is just clamped in the L-shaped groove, so that the relative position relationship between the main reinforcement bar 1 and the first gear 51 or the second gear 91 is locked.
[0034] Refer to Figure 1 - Figure 3, each support rod 41 is provided with a second limiting device 6. The second limiting device 6 is located below the cross bar 42. The second limiting device 6 is used to lock the relative position relationship between the two corners of the ring stirrup 2 far from the cross bar 42 and the main reinforcement 1. Each second limiting device 6 includes a sleeve 61, an inner rod 62 and a dial 63. The sleeve 61 is sleeved on the support rod 41, and the sleeve 61 is slidably connected with the support rod 41. Inner rods 62 are inserted into both sides of the sleeve 61. Each inner rod 62 is slidably connected with the sleeve 61. The mutually remote ends of the two inner rods 62 are used to abut against the main reinforcement 1. A chute 611 is also formed on the sleeve 61. A dial 63 is fixedly connected to each inner rod 62. The end of each dial 63 far from the inner rod 62 passes through the outside of the chute 611. By controlling the sliding of the dial along the chute 611, the inner rod 62 can be driven to slide relatively within the sleeve 61. U-shaped plates 10 are fixedly connected to the mutually remote ends of the two inner rods 62. When the inner rod 62 abuts against the main reinforcement 1, the main reinforcement 1 is clamped in the notch of the U-shaped plate.
[0035] Refer to Figure 1 - Figure 3 , a pushing device 9 is arranged between the two dials of each lifting device 4. Each pushing device 9 includes a second gear 91, a third rack 92 and a fourth rack 93. The second gear 91 is fixedly connected with the sleeve 61. The third rack 92 and the fourth rack 93 are respectively located on both sides of the second gear 91. The moving directions between the third rack 92 and the fourth rack 93 are relatively away from each other. The third rack 92 and the fourth rack 93 are both meshed with the second gear 91. The mutually remote ends of the third rack 92 and the fourth rack 93 are used to abut against the dial 63.
[0036] Refer to Figure 1 - Figure 3 , lifting devices 7 are arranged on both sides of each support rod 41. Each lifting device 7 is located between the base 3 and the sleeve 61. Each lifting device 7 includes a fixed rod 71, a lifting rod 72 and a setscrew 73. One end of the fixed rod 71 abuts against the base 3. A lifting groove is formed at the end of the fixed rod 71 far from the base 3. One end of the lifting rod 72 is inserted into the lifting groove. The lifting rod 72 is slidably connected with the lifting groove. The other end of the lifting rod 72 is used to be fixedly connected with the sleeve 61. By controlling the displacement of the lifting rod 72 in the lifting groove, the sleeve 61 can be controlled to slide up and down along the support rod 41. After the relative position relationship between the lifting rod 72 and the lifting groove is determined, the setscrew 73 is passed through the side wall of the lifting groove to abut against the lifting rod 72, and the locking of the relative position relationship between the lifting rod 72 and the lifting groove can be completed.
[0037] Refer to Figure 1 - Figure 3, a dovetail groove 31 is formed on the base 3. One ends of several support rods 41 fixedly connected to the base 3 are all fixedly connected with dovetail bars 411. The dovetail groove 31 is slidably connected with the dovetail bars 411, so that each of the several lifting devices 4 is slidably connected with the base 3. A locking structure 8 is correspondingly arranged on each support rod 41. Each locking structure 8 includes a collar 81, a locking rod 82 and a plugging ring 83.

[0038] The implementation principle of an auxiliary bracket for tying beam reinforcement bars in an embodiment of the present application is as follows: when using this auxiliary bracket, first adjust the position of the lifting device 4 until there is one lifting device 4 in each unit formed by the hoop stirrups 2 and the main reinforcement bars 1; then push the collar 81 to move along the support rod 41 until the locking rod 82 abuts against the base 3, and then rotate the plugging ring 83 until the plugging ring 83 abuts against the collar 81, that is, the locking of the relative position relationship between the lifting device 4 and the base 3 is completed; then rotate the first gear 51, the first gear 51 drives the first rack 52 and the second rack 53 to displace in opposite directions until both the first rack 52 and the second rack 53 abut against the main reinforcement bars 1 on both sides of the support rod 41, so that the main reinforcement bars 1 abut against the hoop stirrups 2. Then push the lifting rod 72, and the lifting rod 72 moves along the lifting groove until the position of the sleeve 61 is horizontal with the main reinforcement bar 1 that abuts against the hoop stirrups 2 in the direction away from the cross bar 42. Then drive the second gear 91 to rotate. The rotation of the second gear 91 drives the third rack 92 and the fourth rack 93 to move in opposite directions. The third rack 92 and the fourth rack 93 push the dial plates 63 on both sides of the support rod 41 to move in opposite directions, so that the inner rods 62 on both sides of the support rod 41 move in opposite directions along the sleeve 61 until the inner rods 62 abut against the main reinforcement bars 1 and the main reinforcement bars 1 abut against the hoop stirrups 2. By operating the above steps on several lifting devices 4, the main reinforcement bars 1 and the hoop stirrups 2 at the positions where the main reinforcement bars 1 and the hoop stirrups 2 need to be tied are all abutted against each other. Then tie the intersection points of the main reinforcement bars 1 and the hoop stirrups 2 in sequence to complete the tying operation.
