Description
Technical Field

[0002] As an important component of bridges, piers serve to support the bridge deck above and connect to the pile foundation below. During the construction of piers, a steel reinforcement cage must first be made. The steel reinforcement cage consists of several parallel main bars arranged at equal intervals along the circumference of the pier, as well as several stirrups connecting the main bars.
[0003] Currently, steel cages are manufactured by manual binding. When binding the steel cage, workers first arrange the main bars according to requirements, and then bind the stirrups on the main bars. Since the main bars and stirrups need to be distributed at equal intervals during binding, workers need to measure the installation distance of each main bar and each stirrup to ensure that it meets the construction requirements. This not only results in a large workload for workers, but also leads to low construction efficiency. Utility Model Content

In addition, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.
[0018] like Figure 1 As shown in the figure, this utility model embodiment provides a bridge pier rebar tying frame, which includes a lower support frame 1, an upper support frame 2, a first stirrup positioning plate 3, a second stirrup positioning plate 4, a first main reinforcement positioning plate 5, and a second main reinforcement positioning plate 6. The tops of the upper support frame 2 and the lower support frame 1 are detachably connected, and a tying space is reserved between the upper support frame 2 and the lower support frame 1 for tying the pier rebar. Specifically, the lower support frame 1 is used to support the bottom main reinforcement of the pier rebar cage, and the upper support frame 2 is used to support the top main reinforcement of the pier rebar cage.
[0019] Continue to refer to Figure 1 As shown, the top of the lower support frame 1 is connected to two first stirrup positioning plates 3, which are symmetrically and parallelly arranged. Each first stirrup positioning plate 3 has multiple first positioning grooves 31 evenly spaced along its length. The top of the lower support frame 1 is also connected to two first main reinforcement positioning plates 5, which are symmetrically and parallelly arranged. The first main reinforcement positioning plates 5 are perpendicular to the first stirrup positioning plates 3, and each first main reinforcement positioning plate 5 has multiple third positioning grooves 51 evenly spaced along its length. The lowest point of each third positioning groove 51 is higher than the lowest point of each first positioning groove 31. During the reinforcement cage binding, placing the bottom main reinforcement bars in the third positioning grooves 51 ensures that the bottom main reinforcement bars are evenly spaced, improving the spacing qualification rate. This eliminates the need for manual measurement of installation distances, thereby reducing worker workload and improving construction efficiency. In addition, since the stirrups are tied after the main reinforcement is arranged, the lowest point of the third positioning groove 51 is set higher than the lowest point of the first positioning groove 31. Therefore, when tying the stirrups, it is not necessary to raise the bottom main reinforcement so that the stirrups can pass through the bottom of the bottom main reinforcement.
[0020] In practical applications, the top of the upper support frame 2 is detachably connected to two second main reinforcement positioning plates 6, which are symmetrically and parallelly arranged. Each second main reinforcement positioning plate 6 has multiple fourth positioning grooves 61 evenly spaced along its length. Specifically, placing the top main reinforcement bars within the fourth positioning grooves 61 ensures that the top main reinforcement bars are evenly spaced, improving the spacing accuracy rate. This eliminates the need for manual measurement of installation distances, thereby reducing worker workload and improving construction efficiency.
[0021] Continue to refer to Figure 1As shown, the top of the upper support frame 2 is detachably connected to two second stirrup positioning plates 4, which are symmetrically and parallelly arranged. The second stirrup positioning plates 4 are perpendicular to the second main reinforcement positioning plate 6. Each second stirrup positioning plate 4 has multiple second positioning grooves 41 evenly spaced along its length. The lowest point of each second positioning groove 41 is higher than the lowest point of the fourth positioning groove 61, and each second positioning groove 41 corresponds one-to-one with a first positioning groove 31. The first positioning groove 31 and the second positioning groove 41 cooperate to position the stirrups during the binding of the main reinforcement. Specifically, since the stirrups are bound only after the main reinforcement is arranged, the lowest point of the fourth positioning groove 61 is set lower than the lowest point of the second positioning groove 41 to ensure that the stirrups can pass through the top of the top main reinforcement during binding. During the reinforcement cage binding, the main reinforcement bars are first placed in the third positioning groove 51 and the fourth positioning groove 61 respectively. Then, the stirrups are placed in the corresponding positions of the first positioning groove 31 and the second positioning groove 41 to achieve the positioning of the stirrups. Then, the stirrups are bound to the main reinforcement bars. The stirrup binding operation is repeated continuously to complete the binding of the reinforcement cage. After binding is completed, the second stirrup positioning plate 4 is removed first, then the upper support frame 2 is removed, and then the reinforcement cage is transported to the designated location by a hoisting device. The bridge pier column reinforcement binding jig of this application does not require manual measurement of installation distance during use, thereby improving construction efficiency and reducing the workload of workers.
[0022] This utility model embodiment provides a bridge pier rebar binding frame, which includes a lower support frame 1, an upper support frame 2, a first stirrup positioning plate 3, a second stirrup positioning plate 4, a first main reinforcement positioning plate 5, and a second main reinforcement positioning plate 6. The tops of the upper support frame 2 and the lower support frame 1 are detachably connected, and a binding space for binding the pier rebar is reserved between the upper support frame 2 and the lower support frame 1. The top of the lower support frame 1 is connected to two first stirrup positioning plates 3, which are symmetrically and parallelly arranged. The first stirrup positioning plates 3 have multiple first positioning grooves 31 that are equally spaced along their length. The top of the lower support frame 1 is connected to two first main reinforcement positioning plates 5, which are symmetrically and parallelly arranged. The first main reinforcement positioning plates 5 and the first stirrup positioning plates 3 are perpendicular, and the first main reinforcement positioning plates 5 have multiple third positioning grooves 51 that are equally spaced along their length, with the lowest point of the third positioning groove 51 being higher than the lowest point of the first positioning groove 31. Two second main reinforcement positioning plates 6 are detachably connected to the top of the upper support frame 2. These two plates are symmetrically and parallel. Each second main reinforcement positioning plate 6 has multiple fourth positioning grooves 61 evenly spaced along its length. Two second stirrup positioning plates 4 are also detachably connected to the top of the upper support frame 2. These plates are symmetrically and parallel. The second stirrup positioning plates 4 are perpendicular to the second main reinforcement positioning plates 6. Each second stirrup positioning plate 4 has multiple second positioning grooves 41 evenly spaced along its length. The lowest point of each second positioning groove 41 is higher than the lowest point of each fourth positioning groove 61, and each second positioning groove 41 corresponds to a first positioning groove 31. During the reinforcement cage binding, the main reinforcement bars are first placed in the third positioning groove 51 and the fourth positioning groove 61, respectively. Then, the stirrups are placed in the corresponding first positioning grooves 31 and second positioning grooves 41 to achieve stirrup positioning. Finally, the stirrups are bound to the main reinforcement bars. This process of binding the stirrups is repeated to complete the reinforcement cage binding. After the binding is completed, the second stirrup positioning plate 4 is removed first, followed by the upper support frame 2. Then, the steel cage is transported to the designated location using a hoisting device. The bridge pier steel reinforcement binding frame of this application eliminates the need for manual measurement of installation distances during use, thereby improving construction efficiency and reducing worker workload.
[0023] In practical applications, the first stirrup positioning plate 3 and the lower support frame 1 are detachably connected. Making the first stirrup positioning plate 3 and the lower support frame 1 detachable facilitates quick replacement of the first stirrup positioning plate 3.
[0024] like Figure 1As shown, the lower support frame 1 includes a base 11 and crossbars 12. Multiple crossbars 12 are connected to the top of the base 11, and these crossbars 12 are spaced apart along the length of the base 11. A first main reinforcement positioning plate 5 is detachably connected to each of the two outermost crossbars 12. In practical applications, the first main reinforcement positioning plate 5 supports the bottom main reinforcement, and the crossbars 12 support the first main reinforcement positioning plate 5 to ensure the stability of the bottom main reinforcement.
[0025] In practical applications, the upper support frame 2 includes multiple support frames 21. These support frames 21 are spaced apart along the length of the lower support frame 1 and are parallel to each other. Each support frame 21 is detachably connected to the top of the lower support frame 1. A second main reinforcement positioning plate 6 is detachably connected to each of the two outermost support frames 21. Specifically, the support frames 21 provide stable support for the top main reinforcement.
[0026] like Figure 1 As shown, the support frame 21 includes a telescopic member 211, a first support rod 212, and a second support rod 213. The top of the second support rod 213 is detachably connected to the second main rib positioning plate 6. Both the first support rod 212 and the second support rod 213 are located above the lower support frame 1 and are detachably connected. A telescopic member 211 is connected to one of the opposite ends of the first support rod 212 and the second support rod 213, and the other end of the telescopic member 211 is detachably connected to the top of the lower support frame 1. Specifically, the first support rod 212 and the second support rod 213 are inserted into each other. Before binding the reinforcing cage, the first support rod 212 and the second support rod 213 are connected together. Then, the other end of the expansion joint 211 is connected to the top of the lower support frame 1. Finally, the expansion joint 211 is extended to move the second main reinforcement positioning plate 6 to the required height. After the reinforcing cage is bound, the expansion joint 211 is shortened to adjust the height of the second main reinforcement positioning plate 6 so that the second main reinforcement positioning plate 6 can be removed from between the two main reinforcement bars on the side of the reinforcing cage. Then, the expansion joint 211 and the lower support frame 1 are separated. Finally, the first support rod 212 is moved away from the second support rod 213 to separate the first support rod 212 and the second support rod 213, thereby realizing the rapid dismantling of the upper support frame 2 and further improving construction efficiency.
[0027] Continue to refer to Figure 1As shown, the telescopic component 211 includes a supporting outer cylinder 2111, a supporting inner cylinder 2112, and a fixing bolt 2113. One end of the supporting outer cylinder 2111 is detachably connected to the top of the lower supporting frame 1, and the other end is fitted onto the supporting inner cylinder 2112. The supporting inner cylinder 2112 can slide within the supporting outer cylinder 2111, and the end of the supporting inner cylinder 2112 facing away from the supporting outer cylinder 2111 is detachably connected to the corresponding first support rod 212 or second support rod 213. A threaded hole is provided on the supporting outer cylinder 2111, and the threaded end of the fixing bolt 2113 is tightened into the threaded hole and abuts against the supporting inner cylinder 2112. In practical use, when it is necessary to adjust the height of the telescopic component 211, the fixing bolt 2113 is turned to separate the threaded end of the fixing bolt 2113 from the inner support cylinder 2112. Then the inner support cylinder 2112 is slid to the required height, and then the fixing bolt 2113 is tightened to make the threaded end of the fixing bolt 2113 abut against the inner support cylinder 2112. The structure is simple and the adjustment efficiency is high.
