Description

Technical Field

[0001] The utility model belongs to the technical field of bridge pier column structure construction, in particular to a pier column steel bar integral binding cradle tooling. Background Art

[0002] The integral binding cradle for steel cages is a commonly used structural support method in construction and civil engineering. It is mainly used in the construction of concrete structures to ensure that the steel bars in the concrete are correctly arranged and tightly connected, thereby improving the strength, stability and durability of the structure.

[0003] The traditional pier column reinforcement construction is to pre-embed a part of the steel bars during the foundation construction. After the foundation construction is completed, the main reinforcement of the pier column is connected to the pre-embedded steel bars by welding and other methods. The main reinforcement and stirrups of the pier column reinforcement are all installed on-site. The accuracy is difficult to control and cannot be constructed on a large scale. In addition, the upper stirrups of the pier column reinforcement are far from the ground, requiring workers to climb to a high place to tie them, which is more dangerous during operation.

[0004] Therefore, in order to avoid working at heights, the pier column steel bars are directly tied on the ground, and then the finished steel bars are erected for use. However, since the pier column steel bars are usually thicker, dense stirrups are needed to surround a large number of main bars, and the weight of the steel bars themselves is also large, so a lot of positioning mechanisms need to be designed to fix the main bars and stirrups. After the tying of the pier column steel bars is completed, the various fixing devices need to be dismantled before the steel cage can be lifted. The operation is very cumbersome, time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0034] Example

[0035] like Figures 1 to 14 As shown, a pier column reinforcement integral binding frame tooling includes:

[0036] Support rods 1, several support rods 1 are arranged at a fixed distance, and the support rods 1 are arranged in an L shape.

[0037] The guide rails 2 are arranged on the upper end surface of the support rod 1 at a fixed distance. A plurality of first limiting protrusions 21 are evenly distributed along the axial direction on the guide rails 2, and a slot for clamping the stirrup 81 is formed between two adjacent first limiting protrusions 21.

[0038] The clamping shaft 5 is provided with at least one clamping shaft 5, and both ends of the clamping shaft 5 have connecting shafts 52, which are rotatably set on the vertical edge of the support rod 1 through the connecting shaft 52. The clamping shaft 5 has several arc-shaped second limiting protrusions 51 evenly distributed along the axial direction, and a clamping groove for clamping the stirrup 81 is formed between two adjacent second limiting protrusions 51; the first limiting protrusion 21 and the second limiting protrusion 51 are respectively provided.

[0039] Reference Figure 5 and Figure 9 As shown, the bottom end of the annular stirrup 81 is placed on the guide rail 2 and is limited by the first limiting protrusion 21, while one side of the stirrup 81 is tightly attached to the clamping shaft 5 and is limited by the second limiting protrusion 51. In this way, the annular stirrup 81 can be completely limited. When the steel cage is completed, it is only necessary to rotate the clamping shaft 5 so that the second limiting protrusion 51 is separated from the stirrup 81 to release the vertical limit, thereby directly realizing the lifting of the steel cage. Figure 9 As shown, at this time, the second limiting protrusion 51 rotates to the side of the main reinforcement 8, and the stirrup 81 can be limited and fixed on the side; Figure 10As shown, the second limiting protrusion 51 rotates away from the stirrup 81, and the vertical limit of the stirrup 81 is released. This method not only effectively fixes the steel bars, but also allows for quick and easy release of the steel bar limit. Once the pier column reinforcement is tied, the steel cage can be hoisted immediately, making the operation simple and convenient.

[0040] Furthermore, two clamping shafts 5 are provided at a fixed distance apart to limit the stirrups 81 more stably.

[0041] Furthermore, both ends of the second limiting protrusion 51 extend smoothly to the outer wall of the clamping shaft 5, and the angle between the two ends of the second limiting protrusion 51 and the center of the clamping shaft 5 is less than or equal to 180°. Figure 14 , d1 is recorded as the outer contour line of the second limiting protrusion 51. At this time, the two sides of d1 intersect with the center line a1 of the clamping shaft 5. At this time, the angle between the two ends of the second limiting protrusion 51 and the center of the clamping shaft 5 is equal to 180°, and the second limiting protrusion 51 occupies the entire semicircle of the clamping shaft 5; c1 is recorded as another outer contour line of the second limiting protrusion 51. At this time, the two sides of c1 intersect with b1. At this time, b1 and a1 have an angle. At this time, the angle between the two ends of the second limiting protrusion 51 and the center of the clamping shaft 5 is less than 180°. In other words, the purpose of such a limitation is to limit the stirrup 81 by the second limiting protrusion 51 set on one side of the clamping shaft 5. At the same time, when the clamping shaft 5 rotates, the second limiting protrusion 51 can be moved away from the stirrup 81, and only the side of the stirrup 81 can be attached to the outer wall of the clamping shaft 5. When the second limiting protrusion 51 loses its limit, subsequent lifting operations can be facilitated.

[0042] In the present invention, a slider 3 is slidingly provided on the guide rail 2, and a limit frame 4 is provided on the upper end of the slider 3. There are two sliders 3 and two limit frames 4 respectively. A plurality of third limit protrusions 41 are evenly distributed on the inner wall of the limit frame 4, and a slot for clamping the main reinforcement 8 is formed between two adjacent third limit protrusions 41. The stirrups 81 are installed on the guide rail 2 between the two limit frames 4. A plurality of annular stirrups 81 are placed on the guide rail 2, and the sides are limited by the clamping shaft 5, while the main reinforcement 8 is arranged inside the stirrups 81 and around the inner wall of the stirrups 81. The two ends of the main reinforcement 8 extend to both sides of the limit frame 4. Figure 5 and Figure 9 During installation, first place the stirrup 81 in the slot between the first limiting protrusions 21. The side of the stirrup 81 is limited by the slot between the second limiting protrusions 51. Then, the main reinforcement 8 is passed through the inside of the stirrup 81 and placed in the slot between the third limiting protrusions 41. There is a lack of fixation for the main reinforcement 8 between the uppermost third limiting protrusions 41, and the main reinforcement 8 needs to be fixed with tools such as wire.

[0043] Furthermore, a cylinder 6 is provided on the support rod 1, and a connecting block 32 is provided at the bottom end of the slider 3. The piston rod 61 of the cylinder 6 is connected to the connecting block 32 for transmission. The cylinder 6 can drive the slider 3 and the limiting frame 4 to move as a whole. The purpose of this is that when the main reinforcement 8 and the stirrups 81 are all tied, the cylinder 6 can be driven to retract, causing the cylinder 6 to drive the limiting frame 4 to slide, so that the limiting frame 4 is separated from the main reinforcement 8, facilitating the subsequent lifting of the steel cage as a whole.

[0044] In the utility model, the pier column steel bar integral binding frame tooling also includes a driving mechanism for driving the clamping shaft 5 to rotate, the driving mechanism includes a motor 7, a pulley 71 and a belt 72, the ends of the two clamping shafts 5 are provided with pulleys 71, the two pulleys 71 are connected by a belt 72, one of the clamping shafts 5 is connected to the output shaft of the motor 7 for transmission, and the rotation of the clamping shaft 5 is controlled by the motor 7 to realize the limited fixation of the side of the stirrup 81 or the release of the fixation of the stirrup 81.

[0045] Furthermore, a top block 22 is provided in the middle of the upper end of the guide rail 2 , and sliding planes 23 are provided on both sides of the top block 22 . The first limiting protrusion 21 is provided on the top block 22 .

[0046] Furthermore, a slide groove 31 is provided at the bottom end of the slider 3, and the side walls of the slide groove 31 are set close to the side walls of the top block 22. The bottom end of the slider 3 is slidably set on the sliding plane 23, and the upper end surface of the first limiting protrusion 21 is spaced from the upper wall of the slide groove 31. In this way, during the movement of the slider 3, it will not collide with the first limiting protrusion 21, thereby avoiding crushing the first limiting protrusion 21.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
