Description

Technical Field

[0001] This utility model relates to the field of anti-floating technology for internal formwork steel templates, and in particular to an anti-floating device for internal formwork steel templates of box girders. Background Technology

[0002] The traditional method for controlling the floating of the inner formwork of box girders is to pour the bottom plate and web plate in stages. However, this method has a long construction time, requires adjustment of the concrete workability according to the location, and the concrete joints are obvious after the beam is formed, which can easily lead to poor joints and reduce the service life of the project.

[0003] A precast box girder template structure for preventing floating, disclosed in CN211221239U, includes an inner mold, a precast platform, and an outer mold. The inner mold is located above the precast platform, and the outer mold is positioned on both sides of the platform. A crossbeam is mounted on the outer mold directly above the inner mold, and a pressing device is mounted on the crossbeam. The pressing device includes a servo motor, a three-axis gear transmission box, and pressing rods. Two grooves are formed on the side of the crossbeam, and two pressing rods are vertically slidably mounted on the two grooves. Transmission gears are mounted on the two output shafts of the three-axis gear transmission box, and transmission racks are mounted on the pressing rods vertically. This invention uses a servo motor to drive the three-axis gear transmission box to rotate. The transmission gears on the two output shafts of the three-axis gear box drive the transmission racks and pressing rods on both sides to move downwards simultaneously, thereby supporting the inner mold through the two pressing rods and preventing floating.

[0004] The above technical solution cannot fully guarantee the continuity at both ends after solidification, and the ends may be closed, affecting the quality of the box girder after solidification. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for preventing the steel formwork of box girders from floating.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for preventing the steel formwork of a box girder from floating includes a U-shaped module, with abutment sealing plates on both sides of the U-shaped module, and an inner formwork assembly passing through both abutment sealing plates.

[0008] The lower ends of the U-shaped module are fixed with base plates on both sides. The base plates are provided with limiting mechanisms, and the two limiting mechanisms are respectively connected to two abutting sealing plates.

[0009] A fastening mechanism is provided between the two contact sealing plates. Fixed collars are installed on both sides of the U-shaped module. An L-shaped rod is slidably installed on the fixed collar. The two L-shaped rods are detachably connected. A screw is rotatably sleeved on the fixed collar. A fixed plate is fixed on the L-shaped rod. The screw is screwed onto the fixed plate. A push plate is fixed to one end of the L-shaped rod. A telescopic rod is fixed on the push plate. The telescopic rod is fixed to the upper end of the base plate. A push rod is rotatably connected to the push plate. An adaptation mechanism is provided on the push rod. The adaptation mechanism is connected to the contact sealing plate.

[0010] Compared with the prior art, this application can quickly adjust the position of the push plate through the cooperation of corresponding components, so as to control the position height between the contact sealing plate and the U-shaped module, while limiting the position height between the inner mold assembly and the U-shaped module, and can also fully ensure that the contact sealing plate and the U-shaped module make contact and seal, which is convenient for pouring concrete, and can also fully limit the position of the inner mold assembly.

[0011] Preferably, the limiting mechanism includes two bearing frames fixed to the upper end of the base plate, and a sliding plate component is provided through the bearing frame. The two sliding plates component on the same side are fixedly connected to an abutting sealing plate on the same side.

[0012] Furthermore, the support frame effectively limits the sliding plate component, allowing it to move in the direction of the U-shaped module and the lifting direction, so as to control the contact sealing plate to move closer to the U-shaped module and fully adjust the position and height of the inner mold assembly.

[0013] Preferably, the fastening mechanism includes four threaded sleeves disposed on both sides of the U-shaped module, each threaded sleeve being screwed with an L-shaped threaded rod, and rollers mounted on the L-shaped threaded rods. The rollers abut against the U-shaped module, and the four L-shaped threaded rods on the same side are fixedly connected to a sealing plate on the same side.

[0014] Furthermore, by rotating the threaded sleeve, the two L-shaped threaded rods can move relative to each other. In actual production, the opposite ends of the two L-shaped threaded rods are provided with threads in the same direction, but the two ends of the threaded sleeve are provided with reverse threads, or the two L-shaped threaded rods are provided with reverse threads and the threaded sleeve is provided with threads, so as to drive the two L-shaped threaded rods to move relative to each other, and at the same time, the threaded sleeve and the U-shaped module can be in contact, so that the contact sealing plate can be raised and lowered.

[0015] Preferably, a sleeve is provided between two L-shaped rods on the same side, and two screws are screwed onto the sleeve, the screws being screwed into the corresponding L-shaped rods.

[0016] Furthermore, it can fully achieve relative fixation between the two contact sealing plates, and can achieve tight contact between the contact sealing plates and the U-shaped module to avoid leakage.

[0017] Preferably, the adaptation mechanism includes a horizontal plate fixed to the contact sealing plate, and a T-shaped slider is slidably mounted on the lower end of the horizontal plate. The push rod and the T-shaped slider are rotatably connected.

[0018] Furthermore, by adjusting the position of the L-shaped rod, the push plate can be driven to operate. At the same time, when the contact sealing plate moves relative to the U-shaped module, the positional relationship between the T-shaped slider and the horizontal plate can be adjusted.

[0019] The beneficial effects of this utility model are:

[0020] 1. The support frame effectively limits the sliding plate component, allowing it to move in the direction of the U-shaped module and the lifting direction, so as to control the contact sealing plate to move closer to the U-shaped module and fully adjust the position and height of the inner mold component;

[0021] 2. By rotating the threaded sleeve, the two L-shaped threaded rods can move relative to each other.

[0022] 3. The screws can fully fix the two contact sealing plates to each other, ensuring a tight contact between the contact sealing plates and the U-shaped module and preventing leakage. By adjusting the position of the L-shaped rod, the push plate can be driven to operate. At the same time, when the contact sealing plates move relative to the U-shaped module, the positional relationship between the T-shaped slider and the horizontal plate can be adjusted.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-5 A device for preventing the steel template of a box girder from floating includes a U-shaped module 1. Both sides of the U-shaped module 1 are provided with abutting sealing plates 2, and an inner mold assembly 7 is provided through the two abutting sealing plates 2. In actual production and preparation, the abutting sealing plates 2 can support the inner mold assembly 7, and by adjusting the position of the abutting sealing plates 2, the relative position of the inner mold assembly 7 and the U-shaped module 1 can be adjusted to form the box girder mold.

[0031] Reference Figure 1 Both sides of the lower end of the U-shaped module 1 are fixed with a base plate 5. The base plate 5 is equipped with a limiting mechanism. The two limiting mechanisms are respectively connected to the two abutting sealing plates 2. The limiting mechanism can control the movement direction of the abutting sealing plate 2, so that it can only move in the direction of the U-shaped module 1 and up and down, which facilitates relative compression and forms a sealing mechanism.

[0032] Reference Figure 1-5 A fastening mechanism is provided between the two contact sealing plates 2. Fixed collars 16 are installed on both sides of the U-shaped module 1. L-shaped rods 11 are slidably installed on the fixed collars 16. The two L-shaped rods 11 are detachably connected. A screw 15 is rotatably sleeved on the fixed collars 16. A fixed plate 14 is fixed on the L-shaped rods 11. The screw 15 is screwed onto the fixed plate 14. A push plate 12 is fixed at one end of the L-shaped rod 11. A telescopic rod 13 is fixed on the push plate 12. The telescopic rod 13 is fixed to the upper end of the base plate 5. A push rod 10 is rotatably connected to the push plate 12. An adaptation mechanism is provided on the push rod 10. The adaptation mechanism is connected to the contact sealing plate 2. The operation of the L-shaped rod 11 can make the push plate 12 push the push rod 10 to operate. The T-shaped slider 9 can push the horizontal plate 8 to adjust the position of the contact sealing plate 2 relative to the U-shaped module 1. The inner mold assembly 7 can be adjusted to the position height.

[0033] Reference Figure 1The limiting mechanism includes two support frames 4 fixed to the upper end of the base plate 5. A sliding plate 3 is provided through the support frame 4. The two sliding plate 3 located on the same side and the abutting sealing plate 2 on the same side are fixedly connected. The support frame 4 can effectively limit the sliding plate 3, so that the sliding plate 3 can move in the direction towards the U-shaped module 1 and in the direction of lifting, so as to control the abutting sealing plate 2 to move closer to the U-shaped module 1 and fully adjust the position and height of the inner mold assembly 7.

[0034] Reference Figure 1 , 4 The fastening mechanism includes four threaded sleeves 18 on both sides of the U-shaped module 1. Each threaded sleeve 18 is threaded with an L-shaped threaded rod 17. Roller components 6 are mounted on the L-shaped threaded rods 17, and the roller components 6 abut against the U-shaped module 1. The four L-shaped threaded rods 17 on the same side are fixedly connected to the sealing plate 2 on the same side. By rotating the threaded sleeves 18, the two L-shaped threaded rods 17 can move relative to each other. That is, in actual production, the opposite ends of the two L-shaped threaded rods 17 are provided with threads in the same direction, but the two ends of the threaded sleeves 18 are provided with reverse threads, or the two L-shaped threaded rods 17 are provided with reverse threads, and the threaded sleeves 18 are provided with threads, so as to drive the two L-shaped threaded rods 17 to move relative to each other, and at the same time, the threaded sleeves 18 and the U-shaped module 1 abut against each other, so that the sealing plate 2 can be raised and lowered.

[0035] Reference Figure 1 , 5 A sleeve 20 is provided between two L-shaped rods 11 located on the same side. Two screws 19 are screwed onto the sleeve 20 and screwed into the corresponding L-shaped rods 11. This can fully realize the relative fixation between the two contact sealing plates 2 and achieve tight contact between the contact sealing plates 2 and the U-shaped module 1 to avoid leakage.

[0036] Reference Figure 1 , 2 The adapting mechanism includes a horizontal plate 8 fixed on the contact sealing plate 2, and a T-shaped slider 9 slidably mounted on the lower end of the horizontal plate 8. The push rod 10 and the T-shaped slider 9 are rotatably connected. By adjusting the position of the L-shaped rod 11, the push plate 12 can be pushed to operate. At the same time, when the contact sealing plate 2 moves relative to the U-shaped module 1, the adjustment can be made by changing the positional relationship between the T-shaped slider 9 and the horizontal plate 8.

[0037] In this invention, rotating the threaded sleeve 18 allows the two L-shaped threaded rods 17 to move relative to each other. Specifically, during actual production, the opposite ends of the two L-shaped threaded rods 17 are provided with threads in the same direction, but the two ends of the threaded sleeve 18 are provided with threads in opposite directions. Alternatively, the two L-shaped threaded rods 17 may be provided with threads in opposite directions, and the threaded sleeve 18 may be provided with threads inside. This allows the two L-shaped threaded rods 17 to move relative to each other, while simultaneously allowing the threaded sleeve 18 and the U-shaped module 1 to abut, enabling the sealing plate 2 to rise and fall. The screw 19 ensures sufficient relative fixation between the two sealing plates 2, achieving tight contact between the sealing plate 2 and the U-shaped module 1 and preventing leakage. Adjusting the position of the L-shaped rod 11 allows the push plate 12 to operate. Furthermore, when the sealing plate 2 moves relative to the U-shaped module 1, the positional relationship between the T-shaped slider 9 and the horizontal plate 8 can be adjusted.

[0038] The operation of the L-shaped rod 11 enables the push plate 12 to push the push rod 10 to operate, and enables the T-shaped slider 9 to push the horizontal plate 8 to adjust the position of the sealing plate 2 relative to the U-shaped module 1, and adjusts the position height of the inner mold assembly 7.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
