Description

Technical Field

[0001] This utility model relates to the field of bridge steel formwork fixing technology, and in particular to a bridge steel formwork fixing structure for bridge construction. Background Technology

[0002] The technology of steel formwork for bridge construction has been evolving with the increasing complexity of bridge projects, higher environmental protection requirements, and the trend towards intelligentization. In the early days, steel formwork gradually replaced wooden formwork due to its high strength. However, in the construction of complex structures, problems such as low assembly accuracy, poor construction efficiency, and susceptibility to corrosion have been exposed. In addition, the traditional perforated fixing and manual welding process is cumbersome, polluting, and difficult to meet the requirements of new standards.

[0003] The bridge steel formwork fixing structure mainly consists of a modular formwork body (such as high-strength steel or composite plate), an adjustable support system, quick connection components and intelligent monitoring components. The modular design enables rapid assembly of the formwork. The back ribs and bolts are used for ring fastening or hydraulic drive linkage mechanism to perform non-perforated elastic clamping of the formwork, so that each connection node is evenly stressed to avoid grout leakage and deformation.

[0004] During the use of steel formwork, the connection structure of the steel formwork may loosen under high-frequency vibration load, resulting in grout leakage at the joints. Especially in the construction of complex components such as variable cross-section box girders, traditional rigid supports are difficult to adapt to deformation, causing the concrete surface to misalign and exceed tolerances. To address this issue, a bridge steel formwork fixing structure for bridge construction is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bridge steel formwork fixing structure for bridge construction, which aims to improve the problem of loosening and grout leakage at joints caused by high frequency in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bridge steel formwork fixing structure for bridge construction includes an upper fixing formwork and a lower fixing formwork. A connecting plate is externally fixed to both the upper and lower fixing formwork. Two screws are internally engaged with the connecting plate. Multiple transmission rods are rotatably connected to the outside of the connecting plate. A rotating shaft is rotatably connected to the end of each transmission rod away from the connecting plate. A second transmission rod is rotatably connected to the outside of the rotating shaft. A fixing block is rotatably connected to the end of each second transmission rod away from the rotating shaft. Screws are internally engaged with the fixing block. A support assembly is provided externally to the lower fixing formwork. Multiple limiting blocks are internally fixed to the connecting plate. As a further description of the above technical solution: The support assembly includes two connecting blocks. The two connecting blocks are externally fixedly connected to the outside of the lower fixed template. Rotating blocks are rotatably connected to the inside of the two connecting blocks. An outer rod is fixedly connected to the outside of the rotating blocks. An inner rod is slidably connected to the inside of the outer rod. A telescopic column is fixedly connected to the inside of the inner rod. A spring is sleeved on the outside of the telescopic column. A limit block is fixedly connected to the outside of the telescopic column. Multiple limit holes are opened on the outside of the outer rod. As a further description of the above technical solution: One end of the spring is fixedly connected to the outside of the telescopic column, and the other end of the spring is fixedly connected to the outside of the limiting block 1. As a further description of the above technical solution: The outer side of the limiting block slides inside the limiting hole, and the limiting hole is circular in shape; As a further description of the above technical solution: The external rotatable connection of screw two is to the inside of the upper fixed template, and the external rotatable connection of screw one is to the inside of both the upper fixed template and the lower fixed template; As a further description of the above technical solution: Multiple fixing blocks are arranged in an array on the upper and lower sides of the connecting plate, and multiple threaded holes are provided on the exterior of the upper fixing template and the lower fixing template; As a further description of the above technical solution: The bottom of the inner rod is slanted, and multiple limiting grooves are provided on the outside of the upper fixing template and the lower fixing template; As a further description of the above technical solution: The outer side of the second limiting block slides in the limiting groove, and the outer side of the fixing block contacts the outer side of the upper fixing template.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by sliding the connecting plate into the connection between the upper and lower fixed templates, the screw can rotate inside the upper and lower fixed templates to achieve a fixing effect.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a bridge steel formwork fixing structure for bridge construction, comprising an upper fixing template 1 and a lower fixing template 2. A connecting plate 3 is externally fixedly connected to the upper fixing template 1 and the lower fixing template 2. The connecting plate 3 provides initial reinforcement to the upper fixing template 1 and the lower fixing template 2. Two screws 4 are internally engaged with the connecting plate 3, fixing it at the connection point between the upper fixing template 1 and the lower fixing template 2. Multiple transmission devices are externally rotatably connected to the connecting plate 3. Each of the multiple transmission rods 5, at the end furthest from the connecting plate 3, is rotatably connected to a rotating shaft 6. A transmission rod 7 is rotatably connected to the outside of the rotating shaft 6. The transmission rods 5 and the rotating shaft 6 connect the fixing block 8 and the connecting plate 3. Folding via the rotating shaft 6 allows the fixing block 8 to be unfolded and stored. The end of the transmission rod 7 furthest from the rotating shaft 6 is rotatably connected to the fixing block 8. A screw 17 is internally engaged with the fixing block 8. The function of the limiting screw 17 is to fix the fixing block 8, ensuring that the fixing block 8... It can be fixed to the outside of the upper fixed template 1 and the lower fixed template 2. The lower fixed template 2 is provided with a support component on its outside. The support component is used to support the frame around the perimeter and prevent the template from tilting during operation. Multiple limiting blocks 18 are fixedly connected inside the connecting plate 3. The limiting blocks 18 are used to limit the position of the connecting plate 3. The external screw 17 is rotatably connected to the inside of the upper fixed template 1. The external screw 4 is rotatably connected to the inside of the upper fixed template 1 and the lower fixed template 2. The upper fixed template 1 and the lower fixed template 2 are connected by the screw 4, so that the connecting plate 3 can be locked at the connection between the upper fixed template 1 and the lower fixed template 2, so as to achieve a reinforcement effect. Multiple fixing blocks 8 are distributed in an array on the upper and lower sides of the connecting plate 3. Multiple threaded holes are opened on the outside of the upper fixed template 1 and the lower fixed template 2. Multiple threaded holes are opened to facilitate installation and removal. The external of the limiting block 18 slides in the limiting groove. The external of the fixing block 8 is in contact with the external of the upper fixed template 1.

[0012] Reference Figure 1 , Figure 4 and Figure 5The support assembly includes two connecting blocks 9, which are externally fixedly connected to the outside of the lower fixed template 2. A rotating block 10 is rotatably connected inside each of the two connecting blocks 9. An outer rod 11 is fixedly connected to the outside of each rotating block 10. The rotating block 10 drives the outer rod 11 to rotate within the connecting blocks 9, thereby adjusting the angle. An inner rod 12 is slidably connected inside the outer rod 11. The inner rod 12 allows for extension / retraction as the length of the outer rod 11 may be insufficient for different angles. A telescopic column 14 is fixedly connected inside the inner rod 12. A spring 15 is sleeved on the outside of the telescopic column 14. A limit block 16 is fixedly connected to the outside of the telescopic column 14. The telescopic column 14 restricts the position of the limit block 16. The spring 15... The telescopic column 14 and the limiting block 16 are directly compressed and rebounded, allowing the limiting block 16 to slide inside the limiting hole 13, thereby limiting the position of the inner rod 12. The outer rod 11 has multiple limiting holes 13 on its outside. The function of the multiple limiting holes 13 is to fix the inner rod 12 with different length requirements. One end of the spring 15 is fixedly connected to the outside of the telescopic column 14, and the other end of the spring 15 is fixedly connected to the outside of the limiting block 16. The outside of the limiting block 16 slides inside the limiting hole 13. The limiting hole 13 is circular in shape. The bottom of the inner rod 12 is slanted. The purpose of the slanted bottom of the inner rod 12 is to facilitate insertion into the ground, thereby supporting the entire template. The upper fixed template 1 and the lower fixed template 2 have multiple limiting grooves on their outside.

[0013] Working principle: After the workers install the two steel templates, they slide the connecting plate 3 into the joint between the two steel templates. At this time, multiple limiting blocks 18 will slide into the limiting grooves opened on the outside of the upper fixed template 1 and the lower fixed template 2, thereby fixing the connecting plate 3. Then, screw 4 is rotated inside the connecting plate 3, so that screw 4 passes through the threaded holes opened on the upper fixed template 1 and the lower fixed template 2. Then, fixing block 8 is rotated. As fixing block 8 rotates, transmission rod 5 and transmission rod 7 will rotate outside the rotating shaft 6, so that multiple fixing blocks 8 will come close to the outside of the upper fixed template 1. Then, screw 17 is rotated inside the fixing block 8 to fix multiple fixing blocks 8, thereby making the entire connecting plate 3 more firmly fixed. Finally, the upper fixed template 1 and the lower fixed template 2 are reinforced. Then, screw 17 and screw 4 are unscrewed to release the restriction on the connecting plate 3, so that the connecting plate 3 can be removed and the two templates can be dismantled.

[0014] When in use, the operator rotates the rotating block 10, causing the outer rod 11 to rotate synchronously, thereby adjusting the angle. Once the desired angle is reached, the operator presses the limiting block 16. As the limiting block 16 is pressed, the internal spring 15 is compressed, and the telescopic rod of the telescopic column 14 retracts inside the telescopic column 14, causing the limiting block 16 to slide out of the limiting hole 13. This releases the restriction on the inner rod 12, allowing it to slide inside the outer rod 11, thus adjusting its length. After adjusting to the desired length, the spring 15 causes the limiting block 16 to pop outward, sliding into different limiting holes 13, thereby fixing the inner rod 12 and allowing its bottom to better insert into the ground, ultimately supporting the entire frame.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
