Description

Technical Field

[0001] The invention relates to the technical field of equipment for continuous beam cast-in-situ construction, in particular to a reinforcement cage binding jig. Background Art

[0002] Currently, during the cast-in-place construction of continuous beams, steel bar tying is generally done on-site. Positioning and adjusting the steel bars takes a long time, which is not conducive to further shortening the construction period and improving construction efficiency. To improve the efficiency of steel bar tying, steel bar tying jigs are generally used to complete the steel bar tying work.

[0003] As attached Figure 1 As shown in the figure, during cast-in-place continuous beam construction, the height of the continuous beam segments may vary depending on the bridge design requirements (the height difference between the end of the continuous beam closest to the pier and the mid-span can even reach several meters). Accordingly, the inclination angle of the bottom surface of the continuous beam segment will also change. Conventional steel cage binding jigs are not designed to account for the changes in the height and bottom surface inclination of the continuous beam segment and are therefore not suitable.

[0004] Furthermore, tying the steel cage directly on the ground and then hoisting it after tying is not only difficult due to the large height difference, but also places high demands on the lifting equipment and carries high risks during the hoisting process, making it difficult to control the overall construction progress. Furthermore, since it occupies ground space, it requires land approval procedures, which inevitably affects the construction progress. Tying the steel cage on the bridge deck not only reduces land occupation but also reduces costs. Summary of the Invention

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Figures 2 to 5An embodiment of the steel cage binding jig of the present invention is shown. The steel cage binding jig of this embodiment includes a steel inner mold bracket 6 and a steel outer mold bracket 7 arranged on both sides of the steel inner mold bracket 6 in the transverse direction (the transverse direction is the width direction of the beam surface, or the left and right direction, and correspondingly, the longitudinal direction is the length direction of the beam surface, or the front and back direction). A base plate assembly 1 is provided below the steel inner mold bracket 6. The base plate assembly 1 is hinged to a lifting platform assembly 2. The lifting platform assembly 2 (specifically, the upper support plate 21 of the lifting platform assembly 2) is provided with an inclination adjustment assembly 3 for driving the base plate assembly 1 to rotate.

[0026] The steel cage binding jig of this embodiment is provided with a base plate assembly 1 below the steel bar inner mold support 6. The base plate assembly 1 is hinged to the lifting platform assembly 2. The lifting platform assembly 2 is provided with an inclination adjustment assembly 3. The inclination adjustment assembly 3 can drive the base plate assembly 1 to rotate relative to the lifting platform assembly 2, thereby adjusting the inclination angle of the base plate assembly 1. At the same time, the lifting platform assembly 2 can drive the base plate assembly 1 to rise and fall, so that the steel cage binding jig can adapt to the changes in the beam height of the continuous beam segment 5 and the changes in the inclination angle of the base plate. The overall structure is simple and effective.

[0027] Furthermore, in this embodiment, the tilt adjustment assembly 3 includes a first telescopic drive member 31 and a telescopic support rod 32. The upper ends of the first telescopic drive member 31 and the telescopic support rod 32 are hinged to the base assembly 1 via a hinge axis, while the lower ends of the first telescopic drive member 31 and the telescopic support rod 32 are respectively hinged to the lifting platform assembly 2. When the first telescopic drive member 31 is extended or retracted, it drives the base assembly 1 to rotate relative to the lifting platform assembly 2, thereby adjusting the tilt angle of the base assembly 1. This structure is simple and effective. When the first telescopic drive member 31 is extended or retracted, the telescopic support rod 32 also retracts or retracts accordingly. The telescopic support rod 32 cooperates with the first telescopic drive member 31 to provide support for the base assembly 1, ensuring safety and reliability. Of course, in other embodiments, the upper and lower ends can be interchanged, that is, the lower ends of the first telescopic drive member 31 and the telescopic support rod 32 are hinged to the lifting platform assembly 2 via a hinge axis, while the upper ends of the first telescopic drive member 31 and the telescopic support rod 32 are respectively hinged to the base assembly 1.

[0028] As a preferred embodiment, an angle α is formed between the first telescopic driving member 31 and the telescopic support rod 32, and the angle α is 30°≤α≤120°. The first telescopic driving member 31 cooperates with the telescopic support rod 32 to provide reliable support for the base plate assembly 1.

[0029] As a preferred embodiment, the base plate assembly 1 includes multiple parallel bottom beams 11, one end of which is hinged to the lifting platform assembly 2. The lifting platform assembly 2 is equipped with multiple sets of tilt adjustment assemblies 3, which are arranged one-to-one with the multiple bottom beams 11. Compared to a plate material, the multiple bottom beams 11 that constitute the base plate assembly 1 can not only ensure the mechanical strength of the base plate assembly 1 and improve its load-bearing performance, but also reduce the deadweight of the base plate assembly 1.

[0030] Furthermore, in this embodiment, multiple groups of lifting platform assemblies 2 are provided and arranged in parallel. The multiple groups of lifting platform assemblies 2 are connected into a whole by a first connecting beam 41, a second connecting beam 42, and a third connecting beam 43. The first connecting beam 41, the second connecting beam 42, and the third connecting beam 43 are parallel and arranged along the length of the bottom beam 11. One end of the bottom beam 11 is hinged to the first connecting beam 41, the lower end of the first telescopic drive member 31 is hinged to the second connecting beam 42, and the lower end of the telescopic support rod 32 is hinged to the third connecting beam 43. The gravity of the steel cage is transmitted to each bottom beam 11, and then transmitted to the first connecting beam 41, the second connecting beam 42, and the third connecting beam 43 through each bottom beam 11, and then transmitted to each group of lifting platform assemblies 2, thereby achieving distributed load bearing, which is conducive to ensuring that each group of lifting platform assemblies 2 is evenly stressed, further improving the safety and reliability of the mold.

[0031] As a preferred embodiment, the first telescopic driving member 31 is a cylinder. The cylinder technology is mature and reliable and can effectively drive the bottom beam 11 to rotate. Of course, in other embodiments, other existing telescopic driving members can also be used.

[0032] Furthermore, in this embodiment, the lifting platform assembly 2 includes an upper support plate 21, a lower support plate 22, a first connecting rod 23, a second connecting rod 24 and a second telescopic drive member 25. The first connecting rod 23 and the second connecting rod 24 are cross-hinged. The upper end of the first connecting rod 23 is hinged to the upper support plate 21, and the lower end is slidably matched with the lower support plate 22. The lower end of the second connecting rod 24 is hinged to the lower support plate 22, and the upper end is slidably matched with the upper support plate 21. One end of the second telescopic drive member 25 is hinged to the first connecting rod 23, and the other end is hinged to the second connecting rod 24. The second telescopic drive member 25 extends and retracts, causing the angle between the first and second connecting rods 23 and 24 to change. When extended, the angle between the first and second connecting rods 23 and 24 increases, causing the upper support plate 21 to rise, and the first, second, and third connecting beams 41, 42, 43, and bottom beam 11 to rise synchronously with the upper support plate 21. Conversely, when the second telescopic drive member 25 retracts, the angle between the first and second connecting rods 23 and 24 decreases, causing the upper support plate 21 to descend, and the first, second, and third connecting beams 41, 42, 43, and bottom beam 11 to descend synchronously with the upper support plate 21. This provides a simple and reliable structure. The second telescopic drive member 25 preferably utilizes an oil cylinder, which is a mature and reliable technology that can effectively drive the upper support plate 21 up and down. Of course, other existing telescopic drive members may also be used in other embodiments.

[0033] Furthermore, in this embodiment, rollers 26 are respectively provided at the lower end of the first connecting rod 23 and the upper end of the second connecting rod 24, and sliding grooves 27 cooperating with the rollers 26 are respectively provided on the upper support plate 21 and the lower support plate 22. Under the drive of the second telescopic driving member 25, the angle between the first connecting rod 23 and the second connecting rod 24 will change. At the same time, the roller 26 at the lower end of the first connecting rod 23 slides relative to the lower support plate 22, and the roller 26 at the upper end of the second connecting rod 24 slides relative to the upper support plate 21, making the lifting action smoother.

[0034] As a preferred embodiment, a first connecting rod 23 and a second connecting rod 24 are provided on opposite sides of the upper support plate 21, so that the forces on both sides of the upper support plate 21 are kept balanced, which can improve the bearing capacity of the upper support plate 21 and the stability and safety of the lifting process. A synchronization rod 28 is connected between the first connecting rods 23 on both sides and between the second connecting rods 24 on both sides, which can ensure that the first connecting rods 23 and the second connecting rods 24 on both sides move synchronously, avoid tilting of the upper support plate 21, and further improve safety.

[0035] Furthermore, as a preferred embodiment, the steel cage binding jig also includes a T-shaped main frame 8 arranged in the longitudinal direction, with steel inner mold brackets 6 provided on both sides of the T-shaped main frame 8, and both steel inner mold brackets 6 are equipped with steel outer mold brackets 7 and a base plate assembly 1. The steel inner mold brackets 6 on both sides share a T-shaped main frame 8, which makes the size of the steel cage binding jig more compact, reduces the space occupied on the beam surface, and avoids interfering with other construction processes. It is understandable that in other embodiments, the T-shaped main frame 8 can also use other shapes or be separated into two brackets, as long as it can play the role of supporting the steel inner mold bracket 6.

[0036] Furthermore, in this embodiment, guide rails 9 are provided on both sides of the T-shaped main frame 8, and the steel bar outer formwork support 7 is arranged on the guide rails 9. This allows the steel cage outer formwork support 7 to move longitudinally via the guide rails 9 to make room. After the steel cage is tied, the steel cage crane can reach directly above the steel cage for hoisting, avoiding unbalanced loading during hoisting, and making the hoisting process safer and more reliable.

[0037] Furthermore, in this embodiment, the lifting platform assembly 2, T-shaped main frame 8, and guide rails 9 are installed on the cast continuous beam segment 5. The steel cage binding jig is installed on the cast continuous beam segment 5. Compared to installing it on the ground, it can reduce the lifting height, lower the requirements for lifting equipment, and reduce the lifting risk. At the same time, it does not require ground space, eliminating the need for land approval procedures.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
