Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a tall formwork connection structure and a construction and assembly method. Background Art

[0002] The tall formwork connection structure is mainly used in modern construction projects, especially in the construction of complex structures such as high-rise buildings, large bridges, and ultra-wide span stadiums. As an efficient support system, it ensures the stability and accuracy of the formwork through precise design, providing reliable protection for concrete pouring. During the construction process, the tall formwork connection structure not only improves construction efficiency and reduces labor intensity, but also reduces safety risks during construction. Its significance lies in ensuring the quality and safety of construction projects, improving the level of industrialization of construction, and playing an important role in promoting technological progress in the construction industry and realizing architectural modernization.

[0003] Traditional tall formwork connection structures are widely used in the engineering field, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, during the disassembly and assembly process of traditional tall formwork connection structures, workers need to rely on a series of special tools to operate, which makes the disassembly and assembly process cumbersome and complicated. Due to the inconvenience of operation, workers are inefficient and labor-intensive when working at heights. In addition, there is a risk of falling objects from high altitudes during the disassembly and assembly process. Once tools or formwork components fall accidentally, it will pose a serious threat to the safety of workers and equipment below. This risk not only increases the probability of construction accidents, but also makes the safety management of tall formwork operations more challenging. In addition, traditional tall formwork connection structures have certain limitations in design, and they cannot use the weight they bear to tighten themselves. This means that during the construction process, the formwork system requires additional support and fixing measures to ensure stability, which not only increases the complexity and cost of construction, but may also affect the construction progress. Since it cannot be self-locking, this structure may be displaced or deformed when subjected to the pressure of concrete pouring, thereby affecting the accuracy and safety of the building structure. Therefore, this type of structure faces more challenges in its stability and reliability when dealing with large or high-rise building projects, and urgently needs technological innovation to improve its performance.

[0049] Specifically, the spiral groove 512 and the guide hole 59 will cause the guide sleeve 56 and the guide column 510 to rotate in different directions, thereby realizing the opening and closing of the clamping jaw 1 57 and the clamping jaw 2 511 .

This embodiment is different from the first embodiment in that the cross sections of the two ends of the guide hole 45 are the same and in opposite directions, and the two ends of the guide hole 45 are transitioned through a spiral surface in the middle.

[0058] Example 3, reference Figure 1-Figure 12, as a third embodiment of the present invention, provides: a method for constructing and assembling a tall formwork connection structure, comprising the following steps:

[0059] S1, first of all, prepare the materials, connectors and construction equipment required for tall formwork, and provide technical instructions to operators so that they can understand the operation process of the construction project.

[0060] S2, then install the first layer of formwork, adjust and fix the vertical poles, horizontal poles and scissors braces. The connection between the horizontal poles and the vertical poles must maintain sufficient stability to prevent safety hazards caused by increased load-bearing in the later stage of construction.

[0061] S3, then, install the vertical poles and horizontal poles in sequence, use the clamp block 1 to fix the vertical poles, and use the clamp block 2 519 to fix the horizontal poles to ensure that the connection is firm. After fixing, confirmation is required to prevent the situation of loose reinforcement.

[0062] S4. Finally, according to the designed height, lay the formwork, adjust the position and verticality of the formwork, and install horizontal and vertical supports to ensure the overall stability of the formwork system. The stability of the formwork system is related to the quality of the building, so it needs to be confirmed multiple times during the construction process.

[0063] S5. After the construction is completed, a comprehensive inspection of the tall formwork connection structure is carried out, including whether the connection parts are firm and whether the formwork position is correct. A comprehensive inspection can eliminate hidden dangers and ensure that the construction work can proceed normally.

[0064] In summary, the working principle of the present invention is as follows: the steel pipe is placed into the clamping groove 2 of the clamping block 1, and then the latch 429 is removed from the slot 430, thereby releasing the fixation of the latch 429 to the handle 428, the handle 428 is opened, and then the handle 428 is rotated. The handle 428 rotates while driving the shaft sleeve 41 to rotate. The shaft sleeve 41 is constrained by the limit ring 42 and can only rotate in the original position. When the shaft sleeve 41 rotates, the inner wall of the guide hole 45 squeezes the push rod 419 from the side, and the force is transmitted to the sleeve 416 through the push rod 419. The movable shaft 410 is pushed to rotate through the sleeve 416 and the support shaft 417. When the movable shaft 410 rotates, the hexagonal prism 421 is driven to rotate through the hexagonal hole 413. The column 421 drives the bolt to rotate, and the bolt 422 engages with the screw holes on both sides of the clamping block, so that the clamping block clamps the steel pipe. At this time, when the sleeve 41 is rotated in the opposite direction, the inside of the guide hole 45 squeezes the top of the push rod 419, so that the push rod 419 moves toward the inside of the sleeve 416, so that the movable shaft 410 cannot be pushed to rotate, so as to achieve the purpose of making the movable shaft 410 rotate in one direction. When it is necessary to remove the block 1, by pressing the button 412, the button 412 pushes the movable shaft 410 to move in the direction of the screw hole, and at the same time squeezes the top plate 47 through the ball 49, so that the reset spring 46 accumulates force, and when the movable shaft 410 moves, it will drive the sleeve 416 and the push rod 419 to move. The top of the push rod 419 is engaged with the guide hole 45. The inner wall fits well, so it will change direction with the guidance of the inside of the guide hole 45, and the push rod 419 drives the sleeve 416 to rotate together. After the sleeve 416 is subjected to force, it can only rotate around the support shaft 417. At this time, the shaft sleeve 41 is rotated, and the shaft sleeve 41 will only drive the movable shaft 410 to rotate in the opposite direction of the locking clamp block 1, and can drive the bolt 422 to rotate in the opposite direction through the hexagonal prism 421, so as to release the clamping block 1 on the steel pipe, and then release the button 412. The button 412 and the movable shaft 410 will be reset under the action of the reset spring 46. In the same way, the clamp block 2 can be disassembled and assembled. When the clamp block 1 and the clamp block 2 are installed, the clamp block 2 will be subjected to downward pressure, and will drive the sliding sleeve 51 through the side plate 2 518 and the upper plate 516. 3 moves downward, the sliding sleeve 513 drives the outer shaft 514 and the inner shaft 515 to move downward, and the outer shaft 514 moves while the guide sleeve 56 rotates through the pressurized guide hole 59, and the guide sleeve 56 drives the clamping jaw 1 57 to rotate, and the inner shaft 515 moves downward while the guide column 510 rotates through the spiral groove 512, and the guide column 510 rotates while the clamping jaw 2 511 rotates, and the rotation directions of the clamping jaw 1 57 and the clamping jaw 2 511 are opposite. When the sleeve 416 and the sliding sleeve 513 move downward, the clamping jaw 1 57 and the clamping jaw 2 511 approach each other, thereby clamping the steel pipe. As the pressure on the clamping block 2 519 increases, the clamping force of the clamping jaw 1 57 and the clamping jaw 2 511 will also increase. The upper plate 516 compresses the lifting spring 520 while moving downward. When the clamping block 2 519 is not subjected to external pressure,It will be reset under the action of the lifting spring 520.
