Description

Technical Field

[0001] This utility model relates to the field of processing and control technology for pile and column steel reinforcement cages; specifically, this utility model relates to an auxiliary device for positioning and connecting the main reinforcement bars of a steel reinforcement cage. Background Technology

[0002] In recent years, with the rapid development of economic construction, the demand for highway construction has gradually increased. Bridge engineering, as a crucial part of highway construction, plays an indispensable role. Currently, the splicing of pile-column reinforcement cages is increasingly adopting straight thread sleeve connection technology instead of the original welding process. Therefore, the positioning of the main reinforcement bars is particularly important during the actual construction process. However, in practice, inaccurate positioning of the main reinforcement bars leads to misalignment of the main reinforcement bars during on-site splicing, making sleeve connection impossible. Therefore, this problem has been studied. Utility Model Content

[0003] In view of this, the present invention provides an auxiliary device for positioning the main reinforcement bars of a steel cage, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objectives, this utility model provides an auxiliary device for positioning and connecting the main reinforcement bars of a steel cage, comprising:

[0005] A connecting sleeve, the inner cavity of which forms a channel for the connection of two main ribs, and the two ends of the connecting sleeve are provided with insertion holes for the connection ends of the two main ribs.

[0006] The concentric structure is located on the side of the mating sleeve and is used to press the mating ends of the two main ribs from the side to control the concentricity of the two main ribs.

[0007] In the aforementioned auxiliary device for positioning the main reinforcement bars of a steel cage, the docking sleeve may optionally be a hollow tubular structure, and the alignment structure is a set screw threaded through the side of the docking sleeve.

Detailed Implementation

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1 As shown in the figure, this embodiment provides a rebar cage main bar docking and positioning auxiliary device, which is used to dock the processed main bars of the rebar cage with the main bars of the rebar cage to be processed on the rebar cage rolling machine during the processing of the rebar cage.

[0032] The auxiliary device for positioning the main reinforcement bars of the steel cage includes a docking sleeve 1 and a centering structure 2.

[0033] The connecting sleeve 1 has an inner cavity that forms a channel for the two main reinforcing bars to connect. Both ends of the connecting sleeve 1 are provided with insertion holes for the two main reinforcing bars to be inserted. The two main reinforcing bars are in contact inside the connecting sleeve 1.

[0034] The alignment structure 2 is located on the side of the connecting sleeve 1 and is used to press the two main reinforcement bars together from the side to control the alignment of the two main reinforcement bars. When the alignment structure 2 presses the two main reinforcement bars together from the side, it cooperates with the side of the connecting sleeve 1 that is opposite to the pressing direction to achieve alignment and fixation of the two main reinforcement bars together.

[0035] The mating sleeve 1 has a hollow tubular structure, and the alignment structure 2 is a set screw threaded through the side of the mating sleeve 1. Specifically, the mating sleeve 1 can be configured with an inner diameter larger than the outer diameter of the main reinforcement. By screwing the set screw into the channel direction, the set screw is used to compress the main reinforcement, thereby achieving alignment and fixation of the two main reinforcements.

[0036] To facilitate the connection between the set screw and the mating sleeve 1 and to improve the stability of the set screw, a through hole is provided on the side of the mating sleeve 1 for the set screw to pass through. A nut 3 is fixedly installed on the surface of the mating sleeve 1, and the set screw is threadedly engaged with the nut 3. The through hole is a circular hole, which can be directly drilled into the surface of the mating sleeve 1, making processing convenient. The nut 3 can be directly welded to the surface of the mating sleeve 1. The nut 3 ensures that the set screw has sufficient engagement area, thereby improving the stability of the set screw.

[0037] To better accommodate the surface errors and circumferential orientation of the two main reinforcing bars, two set screws are axially arranged on the mating sleeve 1, and the two set screws are parallel to each other, used to press the mating ends of the two main reinforcing bars from the side. Using two set screws to press the two main reinforcing bars separately, compared to using one set screw to press the two main reinforcing bars simultaneously, can better avoid the interference of the main reinforcing bar processing errors and thread orientation on the set screw contact, ensuring the concentricity of the main reinforcing bars.

[0038] like Figures 2 to 4 As shown in Embodiment 2, to further simplify the structure of the positioning aid and more conveniently achieve the alignment operation of the two main ribs, the docking sleeve 1 includes: an openable and closable first cylinder 1.1, used to simultaneously fit the docking ends of the two main ribs when closed. The first cylinder 1.1 has a "V" shape structure, used to align the docking ends of the main ribs with the first cylinder 1.1 when closed. During the closing process of the first sleeve, the inclined walls on both sides of the first sleeve can achieve the alignment of the two main ribs.

[0039] Furthermore, in order to fix the two main reinforcing bars axially and improve the joint stability of the two main reinforcing bars, the joint sleeve 1 also includes:

[0040] The second cylinder 1.2, which can be opened and closed, is used to fit the main rib located on one side of the rolling machine when closed. The second cylinder 1.2 has a "V" shaped structure and is used to align with the main rib when closed.

[0041] The meshing tooth block 1.3 is provided on both the upper and lower sides of the first cylinder 1.1 and the second cylinder 1.2, and is used to insert into the gap between two adjacent threads on the surface of the main rib when the first cylinder 1.1 and the second cylinder 1.2 are closed.

[0042] The second cylinder 1.2 is connected to the first cylinder 1.1, and the distance between them is adjustable. When the second cylinder 1.2 moves closer to the first cylinder 1.1, the two main ribs are axially fixed by the meshing tooth block 1.3 threadedly engaging with the surface of the main rib.

[0043] The tilting of the first cylinder 1.1 and the second cylinder 1.2 is avoided and the concentric structure 2 is formed. Before the first cylinder 1.1 is closed, the meshing tooth block 1.3 on the first cylinder 1.1 is brought into contact with one of the threads on the main bar of the finished steel cage away from the side of the second cylinder 1.2.

[0044] After the second cylinder 1.2 is closed, by moving the second cylinder 1.2 toward the first cylinder 1.1, the meshing tooth block 1.3 on the second cylinder 1.2 contacts one of the threads on the main rib of the rolling mill on one side away from the first cylinder 1.1. At this time, the two meshing tooth blocks 1.3 on the first cylinder 1.1 and the second cylinder 1.2 are in a state of axially pressing the two main ribs relative to each other from both sides, thereby achieving the effect of fixing the two main ribs in the axial direction.

[0045] To facilitate the closing operation of the first cylinder 1.1 and the second cylinder 1.2, the first cylinder 1.1 includes:

[0046] Two first blades 1.1a are rotatably connected at their left ends and connected at their right ends by a first fastening bolt 1.4, which is perpendicular to the axis of the first cylinder 1.1. When the right ends of the two first blades 1.1a are closed, the right ends of the two first blades 1.1a are locked in the closed state by the first fastening bolt 1.4.

[0047] The second cylinder 1.2 includes:

[0048] Two second blades 1.2a are rotatably connected at their left ends, and their right ends are connected by a second fastening bolt 1.5, which is parallel to the axis of the second cylinder 1.2. Since the first cylinder 1.1 is already closed and locked by the first fastening bolt 1.4, closing the second cylinder 1.2 is easier and less strenuous. After the two second blades 1.2a are closed, the second fastening bolt 1.5 is simultaneously passed through the right ends of both second blades 1.2a, locking the right ends of the two second blades 1.2a in the closed state.

[0049] To achieve displacement of the second cylinder 1.2 towards the first cylinder 1.1, two main reinforcing bars are fixed axially. The first cylinder 1.1 also includes:

[0050] Two semi-circular threaded sleeves 1.1b are respectively fixedly installed on the left side of the two first blades 1.1a, so as to form a complete threaded sleeve when the first cylinder 1.1 is closed, and the threads of the semi-circular threaded sleeves 1.1b are adapted to match the second fastening bolt 1.5, and the second fastening bolt 1.5 can be screwed into the two semi-circular threaded sleeves 1.1b.

[0051] The second ends of the two second blades 1.2a are provided with staggered sleeves 1.6 for the second fastening bolts 1.5 to pass through.

[0052] After the first cylinder 1.1 and the second cylinder 1.2 are closed, the second fastening bolt 1.5 achieves thread engagement by screwing it into the two semi-circular threaded sleeves 1.1b. Then, the second fastening bolt 1.5 is rotated to bring the second cylinder 1.2 closer to the first cylinder 1.1. When the meshing teeth on the second cylinder 1.2 are abutted by one of the threads on one side of the main rib of the rolling machine, a clamping force is formed to fix the two main ribs axially.

[0053] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
