Description

Technical Field

[0001] This utility model relates to the field of box girder prefabrication technology, specifically to a steel bar binding jig. Background Technology

[0002] Currently, a large number of precast box girders are used in construction projects such as high-speed railways. The binding and fabrication of the steel reinforcement cage in precast box girders is a key process in the construction of precast box girders. In the existing precast box girder reinforcement binding technology, the precast box girders used in the same project usually have multiple lengths. However, the existing reinforcement binding jigs are fixed in size, and one binding mold can only produce a steel reinforcement cage for one beam length. Therefore, in the construction process of the same project, it is usually necessary to equip multiple sets of reinforcement binding molds of different specifications to meet the different beam length requirements, which leads to problems such as waste of materials, occupation of space, and impact on construction schedule.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a rebar tying jig to solve the technical problem that rebar tying jigs in related technologies cannot be applied to precast box girders of different beam lengths.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a rebar tying jig is provided, which is used to tie the rebars in a precast box girder. The rebar tying jig includes: a jig frame; an installation component, which is fixedly mounted on the jig frame and has a receiving groove formed therein, the extending direction of the receiving groove being consistent with the extending direction of the jig frame; and a rebar positioning plate, which has multiple positioning grooves for placing the rebars. The rebar positioning plate is laid in the receiving groove and is movably set relative to the installation component along the extending direction of the jig frame.

[0006] Furthermore, the mounting component includes a first mounting plate and a second mounting plate disposed opposite to each other, both of which are perpendicular to the jig frame, and a receiving groove is formed between the first mounting plate and the second mounting plate.

[0007] Furthermore, the end of the rebar positioning plate away from the positioning groove is connected to a first plate, which is perpendicular to the rebar positioning plate; the mounting component includes a third mounting plate, one end of which is fixedly connected to the inner wall of the jig, a preset angle is provided between the third mounting plate and the inner wall of the jig, and a receiving groove is formed between the third mounting plate and the inner wall of the jig, in which the first plate is received.

[0008] Furthermore, the rebar tying jig includes a top slab jig for tying the top slab rebar in the precast box girder, and multiple installation components and rebar positioning plates are included. Multiple installation components are spaced apart along the width direction of the top slab rebar, and multiple rebar positioning plates are set one-to-one with the installation components.

[0009] Furthermore, the rebar positioning plate includes a first rebar positioning plate and a second rebar positioning plate located on the top plate jig. There are two first rebar positioning plates, which are located on both sides of the second rebar positioning plate. The first rebar positioning plate includes a first positioning groove, and the second rebar positioning plate includes a second positioning groove. The depth of the first positioning groove is greater than the depth of the second positioning groove.

[0010] Furthermore, the rebar tying jig includes a bottom web jig for tying the bottom web rebar in the precast box girder. The bottom web jig includes a bottom plate jig and a web jig. Multiple installation components and rebar positioning plates are included. Multiple installation components are respectively spaced on the bottom plate jig and the web jig along the width direction of the bottom web jig. Multiple rebar positioning plates are set one-to-one with the installation components.

[0011] Furthermore, the rebar positioning plate includes, in sequence along the extension direction of the jig: a starting section positioning plate, an adjustable section positioning plate, and a tail section positioning plate. The starting section positioning plate, the adjustable section positioning plate, and the tail section positioning plate are movably arranged relative to the installation component. The distance between any two positioning slots in the starting section positioning plate and the tail section positioning plate is smaller than the distance between any two positioning slots in the adjustable section positioning plate.

[0012] Furthermore, the rebar tying jig includes an adjusting component, which includes a slider that is movable along the extension direction of the jig frame. The slider is slidably connected to a slide rail on the jig frame and is connected to a tail section positioning plate to drive the tail section positioning plate to move.

[0013] Furthermore, the adjusting component includes: a lead screw, which is rotatably mounted and threadedly connected to a slider; and a drive mechanism, which is fixedly mounted on the jig and drivenly connected to the lead screw to drive the lead screw to rotate.

[0014] Furthermore, a fixing pin is provided on the tail section positioning plate, and a fixing hole is provided on the slider to accommodate the fixing pin. The fixing pin is connected to the fixing hole so that the slider drives the tail section positioning plate to move.

[0015] Beneficial effects:

[0016] 1. By setting up installation components, the rebar positioning plate can move in or be removed from the receiving groove or installed, thereby realizing the detachable connection between the rebar positioning plate and the jig.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] Example 1

[0036] According to an embodiment of this utility model, a rebar tying jig is provided. Please refer to [link / reference]. Figures 1 to 12The rebar tying jig is used to tie the rebar in the precast box girder. The rebar tying jig includes: a jig frame; an installation component 2, which is fixedly set on the jig frame and has a receiving groove 3 formed inside it, the extending direction of the receiving groove 3 being consistent with the extending direction of the jig frame; and a rebar positioning plate 4, which has multiple positioning grooves 401 for placing the rebar. The rebar positioning plate 4 is laid in the receiving groove 3 and is movably set relative to the installation component 2 along the extending direction of the jig frame.

[0037] By setting the installation component 2, the rebar positioning plate 4 can move in the receiving groove 3, or be removed from the receiving groove 3 or installed, thereby realizing the detachable connection between the rebar positioning plate 4 and the jig. The position of the rebar positioning plate 4 in the installation component 2 can be adjusted according to different beam lengths. One set of rebar tying jigs can be applied to precast box girders of different beam lengths. In addition, the installation component 2 can support and fix the rebar positioning plate to solve the technical problem that the rebar tying jigs in related technologies cannot be applied to precast box girders of different beam lengths.

[0038] In some embodiments, the receiving groove 3 is a through groove extending along the extension direction of the jig, and the rebar positioning plate 4 can be moved to any position in the mounting component 2, thus it can be applied to precast box girders of any beam length, improving the versatility of the rebar tying jig in this embodiment.

[0039] In the rebar tying jig of this embodiment, see Figure 3 The mounting component 2 includes a first mounting plate 21 and a second mounting plate 22 arranged opposite to each other. Both the first mounting plate 21 and the second mounting plate 22 are perpendicular to the jig, and a receiving groove 3 is formed between the first mounting plate 21 and the second mounting plate 22. In this way, the opening of the mounting component 2 faces upward, which facilitates the installation or movement of the rebar positioning plate 4.

[0040] In the rebar tying jig of this embodiment, see Figure 2 The rebar tying fixture includes a top slab fixture 100 for tying the top slab rebar 10 in the precast box girder. Multiple installation components 2 and rebar positioning plates 4 are included, with the installation components 2 spaced apart along the width direction of the top slab rebar 10, and the rebar positioning plates 4 corresponding one-to-one with each installation component 2. By setting multiple installation components 2 and rebar positioning plates 4, the multiple rows of longitudinally arranged rebars in the top slab rebar 10 can be positioned.

[0041] In the rebar tying jig of this embodiment, see Figure 2The rebar positioning plate 4 includes a first rebar positioning plate 411 and a second rebar positioning plate 412 located on the top slab jig 100. Two first rebar positioning plates 411 are located on either side of the second rebar positioning plate 412. Each first rebar positioning plate 411 includes a first positioning groove, and each second rebar positioning plate 412 includes a second positioning groove. The depth of the first positioning groove is greater than the depth of the second positioning groove. Through this arrangement, since the average thickness 10 of the top slab rebar is greater than that of the bottom web rebar 20, the first rebar positioning plate 411 supports the main body of the top slab rebar 10, increasing the erection height of the rebar and ensuring the formation of the top slab rebar 10.

[0042] In some embodiments, see Figure 5 The first rebar positioning plate 411 can be a comb-tooth plate, see [reference]. Figure 6 The second rebar positioning plate 412 can be a circular groove.

[0043] In the rebar tying jig of this embodiment, see Figure 1 The rebar tying fixture includes a bottom web plate fixture 200 for tying the bottom web plate rebars 20 in the precast box girder. The bottom web plate fixture 200 includes a bottom plate frame 201 and a web plate frame 202. Multiple installation components 2 and rebar positioning plates 4 are included. Multiple installation components 2 are spaced apart along the width direction of the bottom web plate fixture 200 on the bottom plate frame 201 and the web plate frame 202. Multiple rebar positioning plates 4 are correspondingly arranged one-to-one with the installation components 2. By setting multiple installation components 2 and rebar positioning plates 4, the multiple rows of longitudinally arranged rebars or stirrups in the bottom web plate rebars 20 are positioned.

[0044] In the rebar tying jig of this embodiment, see Figure 9-12 The rebar positioning plate 4 includes a starting section positioning plate 41, an adjustable section positioning plate 42, and a tail section positioning plate 43 arranged sequentially along the extension direction of the jig. The starting section positioning plate 41, the adjustable section positioning plate 42, and the tail section positioning plate 43 are movably arranged relative to the mounting component 2. The distance between any two positioning slots 401 in the starting section positioning plate 41 and the tail section positioning plate 43 is smaller than the distance between any two positioning slots 401 in the adjustable section positioning plate 42.

[0045] Specifically, by setting the starting section positioning plate 41 and the ending section positioning plate 43, the steel reinforcement density at the starting section of the box girder is increased. When the thickness of the starting section of the box girder is increased, the steel reinforcement strength is sufficient to support the structural strength of the starting section of the box girder. In addition, the starting section positioning plate 41, the adjustable section positioning plate 42, and the ending section positioning plate 43 can be individually adjusted in the installation component 2, thus making them suitable for precast box girders of different beam lengths according to project needs.

[0046] Specifically, the starting section positioning plate 41 and the ending section positioning plate 43 are generally fixed-length positioning plates. When binding precast box girders of different beam lengths, the starting section positioning plate 41 and the ending section positioning plate 43 are both located at the starting section of the entire top slab. It is only necessary to increase or decrease the length of the adjustable section positioning plate 42 located in the middle.

[0047] In the rebar tying jig of this embodiment, see Figure 7 The rebar tying jig includes an adjusting component 5, which includes a slider 51 that moves along the extension direction of the jig frame. The slider 51 is slidably connected to a slide rail 53 mounted on the jig frame. The slider 51 is also connected to a tail section positioning plate 43 to move the tail section positioning plate 43. With this configuration, the tail section positioning plate 43 can be moved independently by the adjusting component 5, allowing the starting section positioning plate 41, the adjustable section positioning plate 42, and the tail section positioning plate 43 to be combined to form different beam lengths.

[0048] Specifically, when adjusting the length of the positioning plate according to the length of the box girder, the initial positioning plate 41 is kept in the same position and length. The length of the adjustable positioning plate 42 is increased or decreased by manual means or by lifting equipment. After the adjustable positioning plate 42 is adjusted, the tail positioning plate 43 is automatically moved towards the adjustable positioning plate 42 by the adjusting component 5, so that the tail positioning plate 43 is aligned with the adjustable positioning plate 42, thereby quickly completing the adjustment of the positioning plate and improving the efficiency of rebar tying.

[0049] Taking the process of adjusting a 32-meter positioning plate to a 30-meter rebar positioning plate as an example, the process of adjusting the length of the positioning plate in this embodiment is explained, with both the initial positioning plate 41 and the final positioning plate 43 being 5 meters long:

[0050] The initial section positioning plate 41 remains stationary. The 2-meter adjustable section positioning plate 42 is removed manually or by lifting equipment. Then, the tail section positioning plate 43 is automatically moved 2 meters toward the adjustable section positioning plate 42 by the adjusting component 5, so that the tail section positioning plate 43 is aligned with the adjustable section positioning plate 42, thereby completing the adjustment of the positioning plate length.

[0051] It should be noted that in the rebar binding jig, there are multiple installation components 2 and tail section positioning plates 43. Multiple sets of adjustment components 5 can be set up, with each tail section positioning plate 43 set up individually. Alternatively, only one set of adjustment components 5 can be designed, and all tail section positioning plates 43 can be moved simultaneously through the linkage structure adjustment components 5.

[0052] In the rebar tying jig of this embodiment, see Figure 7The adjusting component 5 includes: a lead screw 54, which is rotatably mounted and threadedly connected to the slider 51; and a drive mechanism 55, which is fixedly mounted on the frame and drivenly connected to the lead screw 54 to rotate the lead screw 54. Thus, the slider 51 is moved via the drive mechanism 55 and the lead screw 54.

[0053] Understandably, other forms of transmission structures, such as chain and sprocket structures or rack and pinion structures, can also be used to drive the slider 51, depending on the stroke requirements of the tail section positioning plate 43.

[0054] In the rebar tying jig of this embodiment, see Figure 7 The tail section positioning plate 43 is provided with a fixing pin 431, and the slider 51 has a fixing hole for accommodating the fixing pin 431. The fixing pin 431 is connected to the fixing hole so that the slider 51 drives the tail section positioning plate 43 to move. In this way, the slider 51 and the tail section positioning plate 43 are connected as one unit, and the movement of the slider 51 drives the movement of the tail section positioning plate 43. In addition, the fixing hole is an open hole with the opening facing upward, which facilitates the connection of the fixing pin 431 to the fixing hole when installing the tail section positioning plate 43.

[0055] Example 2

[0056] In the rebar tying jig of this embodiment, see Figure 4 The end of the rebar positioning plate 4 away from the positioning groove 401 is connected to a first plate 402, and the first plate 402 is perpendicular to the rebar positioning plate 4; the mounting component 2 includes a third mounting plate 23, one end of the third mounting plate 23 is fixedly connected to the inner wall of the jig, a preset angle is provided between the third mounting plate 23 and the inner wall of the jig, and a receiving groove 3 is formed between the third mounting plate 23 and the inner wall of the jig, and the first plate 402 is contained in the receiving groove 3.

[0057] In some embodiments, the third mounting plate 23 is parallel to the inner wall surface of the frame, the opening of the mounting component 2 faces to one side, and the structure of the mounting component 2 is simpler.

[0058] In some embodiments, the angle between the third mounting plate 23 and the inner wall of the jig can be set to 0-60° according to the position of the rebar positioning plate 4, so as to facilitate the installation of the rebar positioning plate 4.
