Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel bar positioning frame. Background Art

[0002] With the rapid development of bridge construction in my country, prefabricated box girders are increasingly widely used in the construction of various types of bridges as an important building material. Prefabricated box girders are usually manufactured in a special prefabrication plant through a series of processes such as steel bar tying, concrete pouring, curing, tensioning and grouting, and then transferred to the construction site for installation. The core advantage of this prefabrication method is that it can greatly improve construction efficiency and quality control, but its efficiency depends largely on the speed and accuracy of steel bar tying.

[0003] At present, the reinforcement binding of prefabricated box girders is mostly achieved by using a reinforcement binding cradle. However, the existing binding cradle system has many limitations, especially in terms of the positioning and binding accuracy of the reinforcement. For example, the traditional reinforcement binding cradle often has difficulty in accurately controlling the longitudinal spacing of the bottom web stirrups, and the height and linear control of the longitudinal horizontal reinforcement are not ideal. These problems not only affect the stability and safety of the structure, but also lead to the need for additional adjustments and corrections during the subsequent construction process, thereby reducing the overall production efficiency. Utility Model Content

[0004] The utility model aims to provide a steel bar positioning cradle to solve the technical problems of low accuracy and poor adaptability of steel bar binding cradles in the prior art.

[0030] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] See also Figure 1 The steel bar positioning tire frame provided by the embodiment of the utility model includes a support assembly 10 and a positioning shaft 20. Among them, the support assembly 10 includes a support bottom beam 11, two support diagonal braces 12 and two support longitudinal beams 13, the two support longitudinal beams 13 are respectively fixedly connected to the two ends of the support bottom beam 11, one end of the support diagonal brace 12 is fixedly connected to the support bottom beam 11, and the other end of the support diagonal brace 12 is fixedly connected to the support longitudinal beam 13, and a support diagonal brace 12 is provided for each support longitudinal beam 13, and the two support diagonal braces 12 are symmetrically arranged; the positioning shaft 20, the support longitudinal beam 13 and the support diagonal brace 12 are provided with a plurality of positioning holes, and the plurality of positioning holes are arranged at intervals along the height direction, and the positioning holes on the support longitudinal beam 13 and the support diagonal brace 12 on the same side correspond to each other and are coaxially arranged, and a positioning shaft 20 is provided for the two coaxially arranged positioning holes on each horizontal plane, and is slidably connected to the two positioning holes.

[0032] The fixed connection between the supporting diagonal braces 12, the supporting longitudinal beams 13 and the supporting bottom beam 11 enhances the structural stability of the entire tire frame, ensures safety during construction, and can also resist the loads and pressures brought by various machines and environments on site. In addition, the symmetrically arranged diagonal braces maintain the balance of the overall structure, avoid tilting or deformation under heavy loads, and thus ensure the accuracy of the steel bar positioning. By providing a plurality of positioning holes on the supporting longitudinal beams 13 and the diagonal braces, the accuracy of the movement of the positioning shaft 20 is achieved, reducing structural weaknesses or construction quality problems caused by position deviations. The positioning shaft 20 is slidably connected to the positioning holes, so that it is easy to quickly assemble and disassemble the steel bars during actual construction operations, greatly improving work efficiency. When making a large number of prefabricated box girders, the position of the steel bars can be quickly adjusted and fixed, which greatly shortens the production cycle, reduces labor costs, and has higher adaptability.

[0033] Generally speaking, during the construction process, the supporting bottom beam 11 is placed horizontally, and the supporting longitudinal beam 13 is perpendicular to the supporting bottom beam 11 and is arranged at both ends of the supporting bottom beam 11. For the convenience of description in conjunction with the accompanying drawings, the direction below is described in the direction shown in the accompanying drawings, but is not limited thereto. The supporting bottom beam 11, the supporting longitudinal beam 13 and the supporting diagonal brace 12 are welded in pairs. Welding reduces the risk of loosening and displacement of the structure under heavy load or vibration, so as to withstand various dynamic and static loads at the construction site and have high stability. In other embodiments, the connection method can also be bolt connection, etc., which is not limited here. In the actual construction process, the number of the supporting bottom beam 11, the supporting longitudinal beam 13 and the supporting diagonal brace 12 is selected according to the length of the box beam, and then the three are welded in pairs to form a whole. The supporting bottom beam 11, the supporting longitudinal beam 13 and the supporting diagonal brace 12 are processed using steel plate materials commonly used in this field, and their number, shape and material are not excessively limited here.

[0034] In order to facilitate the fixing of the steel bars, a plurality of positioning plates 40 are provided on the support bottom beam 11. The positioning plates 40 extend in a direction perpendicular to the support longitudinal beam 13, and are movably connected to the support bottom beam 11. The positioning plates 40 extend in a direction perpendicular to the support longitudinal beam 13, and are fixed to the support bottom beam 11 by a movably connected manner, so that the positioning plates 40 can be adjusted when necessary to adapt to steel bars of different sizes and shapes, and have high flexibility and adaptability. In addition, in this embodiment, a positioning plate 40 is provided on each of the two supporting diagonal braces 12, so as to further strengthen the support and limiting effect on the steel bars and improve the stability of the steel bars during the binding process.

[0035] Specifically, the support bottom beam 11 is provided with multiple groups of latch teeth along its length direction, and the multiple groups of latch teeth are arranged at intervals along the length direction of the support bottom beam 11. A latch groove is provided on the positioning plate 40 corresponding to each latch tooth, and each group of latch teeth can be latched with the latch groove one by one. The spacing between two adjacent groups of latch teeth can be set according to actual needs, so that when in use, the positioning plate 40 can be adjusted to a suitable position according to the size of different steel bars, and latched with the corresponding latch teeth to achieve the positioning effect of the steel bars. In other embodiments, the positioning plate 40 can also be set to be magnetically connected to the support bottom beam 11, connected to a guide rail, etc., so as to adjust the position of the positioning plate 40, which is not limited here.

[0036] Furthermore, two support frames 50 are provided at the bottom of the support base beam 11, and the two support frames 50 are arranged at intervals along the length direction of the support base beam 11. The support frames 50 provide additional support points for the support base beam 11, thereby increasing the overall stability of the tire frame, and can effectively prevent the positioning tire frame from tilting or moving during the construction process, thereby ensuring the safety and accuracy of the construction. The two support frames 50 not only stabilize the tire frame, but also enhance its carrying capacity, so that the tire frame can support heavier steel bar configurations and adapt to large or heavy-loaded construction requirements without causing structural deformation or damage. In other embodiments, the support frames 50 can also be set to three, four, etc., which are not limited here.

[0037] Furthermore, the positioning holes on the supporting longitudinal beams 13 and the supporting diagonal braces 12 on both sides of the supporting bottom beam 11 correspond to each other and are coaxially arranged, which not only facilitates processing and production, but also evenly distributes loads and stresses, and reduces structural deformation or fatigue caused by uneven loads. The coaxial positioning hole design simplifies the installation and adjustment process of the positioning shaft 20, and the operator can complete the installation task faster without spending extra time to correct the alignment of each hole, reducing the possibility of human error and speeding up the construction progress.

[0038] In addition, the two supporting diagonal braces 12 extend obliquely from bottom to top in the direction close to the supporting longitudinal beam 13, and the supporting diagonal braces 12, the supporting bottom beam 11 and the supporting longitudinal beam 13 on the same side are arranged in a triangle. The triangular structure can effectively resist bending and torsional stress, making the positioning tire frame more stable when bearing vertical or lateral loads, reducing shaking or displacement caused by external forces, and having higher stability.

[0039] Regarding the positioning shaft 20, the steel bar positioning tire frame provided in this embodiment also includes a pull rod 30, and the pull rod 30 extends in the vertical direction. The end of the positioning shaft 20 close to the supporting longitudinal beam 13 can be connected to the pull rod 30. By setting the pull rod 30, a hand-holding portion can be provided for playground personnel, so that the operator can realize the movement process of the positioning shaft 20 by pushing and pulling the pull rod 30. The pull rod 30 is set to a cylindrical rod shape, which is easy to process, easy to assemble and has a high space utilization rate. In other embodiments, the pull rod 30 can also use structures such as handles and grip rings, as long as it can be convenient for the operator to hold it, and it is not limited here.

[0040] In order to improve the flexibility and convenience during operation, at least two pull rods 30 are provided corresponding to the positioning shaft 20 on the same side, and the pull rods 30 are arranged at intervals in the vertical direction, and each pull rod 30 is connected to multiple positioning shafts 20. Thus, by pushing and pulling a pull rod 30, multiple connecting shafts connected thereto can be driven to move synchronously, which improves the operation efficiency and optimizes the convenience during operation. In this embodiment, two pull rods 30 are provided corresponding to the positioning shaft 20 on the same side, so that during use, by pushing and pulling the two pull rods 30, the position adjustment process of multiple positioning shafts 20 connected thereto can be realized, and the position of the pull rod 30 can be adjusted according to the size of different steel bars. After the steel bars are tied, the pull rod 30 is pulled away from the supporting longitudinal rod to pull out the positioning rod, which improves the availability of the device and saves costs. In addition, in this embodiment, the number of positioning shafts 20 connected to each pull rod 30 is the same, which is convenient for production and processing, and easy to assemble with high identity. In some embodiments, different numbers of positioning shafts 20 can also be connected to each pull rod 30 according to actual conditions, which is not limited here. Regarding the number of the tie rods 30 , in other embodiments, three, four or more tie rods 30 may be provided along the height direction of the supporting longitudinal rod, and a plurality of positioning shafts 20 may be provided on each tie rod 30 , which is not limited here.

[0041] In addition, in this embodiment, since the supporting diagonal brace 12 extends obliquely from bottom to top in the direction close to the supporting longitudinal beam 13, the supporting diagonal brace 12 is in an inverted trapezoidal shape. Therefore, in order to make the positioning shaft 20 adapt to the supporting diagonal brace 12 and prevent the positioning shaft 20 from interfering with the binding effect during the process, the length of the positioning shaft 20 inserted into the positioning hole is gradually reduced from top to bottom. By gradually reducing the length of the positioning shaft 20 to adapt to the inverted trapezoidal supporting diagonal brace 12, it can be ensured that the positioning shaft 20 is evenly distributed over the entire diagonal brace length and maintains an appropriate spacing with the diagonal brace, preventing the positioning shaft 20 from interfering with the steel bars or other diagonal brace components during the steel bar binding process, and ensuring smooth construction.

[0042] In order to improve the integrity and stability between the pull rod 30 and the positioning shaft 20, in this embodiment, each positioning shaft 20 is welded to the pull rod 30. In other embodiments, the pull rod 30 and the positioning shaft 20 can also be bolted, pinned, keyed, etc., which will not be repeated here.

[0043] During use, the pull rod 30 can be pulled according to the size of the steel bar to make the positioning shaft 20 slide to the required position in the positioning hole to facilitate the binding of the steel bars. In order to prevent the adjusted positioning shaft 20 from slipping and affecting the binding effect, the steel bar positioning frame also includes a locking piece. A locking piece is provided on each positioning shaft 20. When the locking piece is in a locked state, the positioning shaft 20 cannot move relative to the positioning hole. Therefore, when the positioning shaft 20 moves to the required position, the locking piece is used to lock the positioning shaft 20 to prevent the positioning shaft 20 from shifting and affecting the binding process.

[0044] Specifically, the locking member is a locking latch, and a plurality of limiting holes are provided on the positioning shaft 20 along its own axial direction. The limiting holes penetrate the positioning shaft 20 along its own thickness direction, and the locking latch is selectively inserted into the limiting holes. The multiple limiting holes on the positioning shaft 20 allow the locking latch to be inserted in different positions, thereby adjusting the position of the positioning shaft 20. In order to be suitable for steel bars of different sizes and specifications or different project requirements, the tire frame has higher adaptability and versatility. The installation and adjustment process of the locking latch is simple and quick, and the operator can quickly replace or adjust the position of the positioning shaft 20 without complicated tools or long-term operation, which greatly improves the construction efficiency. In other embodiments, the locking member can also be selected from bolts, buckles, etc., which are not limited here.

[0045] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
