Description

Technical Field

[0001] The utility model belongs to the technical field of ferrules for bridge construction, in particular to a ferrule device for bridge construction. Background Art

[0002] During bridge construction, the hoop assembly, a key component, plays a vital role in ensuring the stability and safety of the bridge structure. Traditional hoop assemblies typically consist of two independent semicircular support plates, each secured to two bridge columns. Bolts then fasten the two ends of the plates together to form a complete hoop. However, this traditional hoop assembly method presents significant technical bottlenecks and efficiency issues.

[0003] First, because the support plate is installed in two halves, the installation process requires precise alignment of the two semicircular structures and ensuring that the bolt holes are completely aligned. This not only increases the difficulty of installation, but also easily affects the overall strength and stability of the ferrule due to installation errors. Secondly, the bolt tightening process is cumbersome and time-consuming, especially when working at height, which greatly increases the difficulty and safety risks of the operator. In addition, after the two independent ferrules are installed, an additional connecting mechanism needs to be installed to connect the two ferrules. Since the connecting mechanism and the ferrule cannot be installed in coordination, this step often becomes a bottleneck that restricts overall work efficiency. Utility Model Content

[0021] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0022] Example

[0023] The embodiment of the present invention is a kind of bridge construction hoop device, such as Figures 1 to 4 As shown, it includes two hoops distributed on the left and right, and the two hoops are respectively mounted on two bridge columns.

[0024] A connecting mechanism is provided between the two hoops, connecting them together. The hoops include a first support plate 1 and a second support plate 2, which are connected to each other to form a complete circular ring. A first connecting plate 4 is fixed to the upper and lower ends of the first support plate 1, while a second connecting plate 5 is fixed to the upper and lower ends of the second support plate 2. Both the first connecting plate 4 and the second connecting plate 5 have open slots that communicate with each other. The first connecting plate 4 and the second connecting plate 5 are integrally formed with the first support plate 1, while the second connecting plate 5 and the second support plate 2 are integrally formed with each other. During use, the first connecting plate 4 and the second connecting plate 5 are connected to each other, so that the first support plate 1 and the second support plate 2 are clamped to the bridge column. The open slot on the lower side opens downward, while the open slot on the upper side opens upward.

[0025] The connecting mechanism includes two fixing sleeves 10 distributed left and right. Two connecting pipes 13 symmetrically distributed up and down are fixed on the outer side walls of the fixing sleeves 10. The connecting ends of the connecting pipes 13 are connected to the detachable crossbeam 6.

[0026] like Figure 3 As shown, connecting tube 13 and crossbeam 6 are connected via a latch 14. A first pin hole is defined in crossbeam 6, and a second pin hole is defined in connecting tube 13. Latch 14 is inserted into both the first and second pin holes. During installation, the swinging end of crossbeam 6 is inserted into the connecting end of connecting tube 13. When the first and second pin holes are aligned, latch 14 is inserted, locking connecting tube 13 and crossbeam 6 together. Latch 14 is designed with a diameter that is thicker at the top and thinner at the bottom, so that the first and second pin holes fit together.

[0027] The hinged end of the upper cross beam 6 independently passes through the open slot of the upper second connecting plate 5 and is hinged to the upper first connecting plate 4, and the hinged end of the lower cross beam 6 independently passes through the open slot of the lower second connecting plate 5 and is hinged to the lower first connecting plate 4.

[0028] Two hinged rings 19 are fixed to the first connecting plate 4, arranged in a front-to-rear arrangement. A common rotating shaft 3 is inserted into these two hinged rings 19. The hinged ends of the crossbeams 6 are fixed to the rotating shaft 3 and swing along the direction of the open slot. During use, the crossbeams 6 swing along the open slot of the first connecting plate 4. After the second support plate 2 is placed between the two crossbeams 6, the two crossbeams 6 are swung together and into the open slot of the second connecting plate 5, confining the second support plate 2 between the two crossbeams 6 and thus restraining it.

[0029] Each crossbeam 6 is independently fitted with a secondary push ring 15. A primary push ring 8 is positioned between the two secondary push rings 15. The primary push ring 8 and the two secondary push rings 15 are connected by a connecting rod 7. A sleeve 17 is independently fitted on the crossbeam 6 between the corresponding secondary push rings 15 and the second connecting plate 5. During use, the primary push ring 8 pushes the two secondary push rings 15 toward one side of the second support plate 2. The secondary push rings 15 push the sleeve 17, which applies a thrust force to the second connecting plate 5, causing the second support plate 2 to cooperate with the first support plate 1 to tighten against the bridge column.

[0030] The secondary push ring 15 is provided with a first opening facing backwards, and the diameter of the beam 6 is smaller than the width of the first opening. The secondary push ring 15 can be installed on the beam 6 through the first opening without passing through the swinging end of the beam 6, which makes it easier to install the secondary push ring 15.

[0031] A support ring 16 is fixed to one end of the sleeve 17, which communicates with the interior of the sleeve 17. A foot plate 18 is fixed to the other end of the sleeve 17. Foot plate 18 has a through hole that communicates with the sleeve 17. Foot plate 18 is independently mounted on the crossbeam 6 and rests against the second connecting plate 5. The support ring 16 and the secondary thrust ring 15 are in contact with each other; the support ring 16, sleeve 17, and foot plate 18 are integral. The support ring 16 increases the contact area between the secondary thrust ring 15 and the sleeve 17, while the foot plate 18 increases the contact area between the sleeve 17 and the second connecting plate 5, thereby improving the transmission of the thrust of the secondary thrust ring 15.

[0032] The front and rear sides of the corresponding opening grooves are fixed with positioning columns 20 on the second connecting plate 5, and the corresponding positioning columns 20 are provided with left and right positioning holes on the foot plate 18; through the cooperation between the positioning holes and the positioning columns 20, the positioning between the foot plate 18 and the second connecting plate 5 is formed, thereby preventing the second connecting plate 5 from shifting during the process of the second support plate 2 clamping the bridge column.

[0033] like Figure 1 As shown, a movable sleeve 9 is provided between the main push ring 8 and the fixed sleeve 10, and a first internal thread with opposite rotation direction is provided in the two movable sleeves 9, and a second internal thread with opposite rotation direction is provided in the two fixed sleeves 10. The first internal thread on the left and the second internal thread on the left have opposite rotation directions, and the first internal thread on the right and the second internal thread on the right have opposite rotation directions; the two movable sleeves 9 and the two fixed sleeves 10 are provided with the same threaded column 12, and the threaded column 12 is threadedly matched with the two movable sleeves 9 and the two fixed sleeves 10.

[0034] In this embodiment, the threads on the threaded column 12 are divided into four sections from left to right. The diameters of the two middle sections of the threaded column 12 are larger than the diameters of the two edge sections. This allows the fixed sleeve 10 to pass through the threaded sections of the two edge sections of the threaded column 12 and fit over the threaded end of the middle section of the threaded column 12, thereby forming a threaded engagement with the threaded end. From left to right, the threaded column 12 has a forward thread, which fits the movable sleeve 9 on the left side; then a reverse thread, which fits the fixed sleeve 10 on the left side; then a forward thread again, which fits the fixed sleeve 10 on the right side; and finally a reverse thread, which fits the movable sleeve 9 on the right side.

[0035] When the threaded column 12 rotates, the two fixed sleeves 10 move closer to the center, while the two movable sleeves 9 move away from each other.

[0036] The main push ring 8 is independently mounted on the threaded post 12, with a limiter positioned between it and the movable sleeve 9. As the two movable sleeves 9 move away from each other, the movable sleeve 9 exerts a thrust on the main push ring 8, causing it to move toward the second support plate 2. The limiter comprises a stopper secured to the movable sleeve 9, with a slot defined in the main push ring 8 for the stopper to engage. During operation, the stopper engages the slot, preventing the movable sleeve 9 from rotating. Only when the movable sleeve 9 is stationary can it be driven by the threaded post 12 to move.

[0037] The primary push ring 8 has a rearward-facing second opening, and the diameter of the threaded post 12 is smaller than the width of this second opening. During installation, this second opening allows the primary push ring 8 to be fitted onto the threaded post 12 without passing through one end of the threaded post 12, facilitating installation of the primary push ring 8. Furthermore, since the secondary push ring 15, connecting rod 7, and primary push ring 8 are all made of metal and possess a considerable weight, they can be placed directly on the crossbeam 6 and threaded post 12 without becoming easily detached.

[0038] A rotating sleeve 11 is mounted on the threaded column 12 between the two fixed sleeves 10. The outer wall of the rotating sleeve 11 is a hexagonal structure. When in use, the rotating sleeve 11 facilitates the rotation of the threaded column 12. The rotating sleeve 11 is located in the middle of the threaded column 12.

[0039] In actual use process:

[0040] The first support plate 1 is located on one side of the bridge column, and the second support plate 2 is located on the other side of the bridge column. The two crossbeams 6 are then swung together to constrain the second support plate 2 between the two crossbeams 6. The fixed sleeve 10, threaded column 12, and movable sleeve 9 are assembled. During installation, the fixed sleeve 10 on the left side passes through the left end of the threaded column 12, fits over the second threaded section, and forms a threaded fit with it. The fixed sleeve 10 on the right side passes through the right end of the threaded column 12, fits over the third threaded section, and forms a threaded fit with it. The movable sleeve 9 on the left side fits over the first threaded section of the threaded column 12, and forms a threaded fit with it. The movable sleeve 9 on the right side fits over the fourth threaded section of the threaded column 12, and forms a threaded fit with it. The two connecting pipes 13 on the left fixed sleeve 10 are respectively connected to the swinging ends of the two crossbeams 6 on the left side, and the two connecting pipes 13 on the right fixed sleeve 10 are respectively connected to the swinging ends of the two crossbeams 6 on the right side. Finally, the secondary push ring 15 and the primary push ring 8 are placed on the threaded column 12 and the crossbeam 6. The secondary push ring 15 fits the support ring 16, and the primary push ring 8 fits the movable sleeve 9. At the same time, the limit block enters the limit groove. Then the threaded column 12 is rotated. Driven by the four threaded segments, the two fixed sleeves 10 move toward the center, while the two movable sleeves 9 move away from each other. The fixed sleeve 10 moves toward the center, driving the first support plate 1 to move toward the second support plate 2. The movable sleeve 9 moves outward, driving the second support plate 2 to move toward the first support plate 1. The first support plate 1 and the second support plate 2 are simultaneously clamped on the bridge column. The hoops on the left and right sides are fixed at the same time. The connection mechanism is also fixed as the hoops are fixed, achieving the purpose of coordinated installation of the two. Correspondingly, the installation steps are simplified, the installation time is reduced, and the overall work efficiency of bridge construction is improved.
