[0024] like Figures 1 to 4 As shown, a schematic diagram of an embodiment of an adjustable steel formwork structure of the present invention includes two steel formworks 6 arranged relatively to each other and a tie assembly arranged between the two steel formworks 6, the tie assembly includes two connecting members 1 and an adjusting member arranged between the two connecting members 1, each connecting member 1 is connected to the corresponding steel formwork 6, and at least one connecting member 1 is movably connected to the adjusting member to adjust the distance between the two steel formworks 6.

[0025] The connection between the connecting member 1 and the adjusting member can be in various forms such as sliding connection or rotation connection. In this embodiment, the adjusting member includes an adjusting sleeve 2 for connecting the two connecting members 1, and the two connecting members 1 are movably connected to the two ends of the adjusting sleeve 2 respectively.

[0026] In this embodiment, each connecting member 1 is internally threadedly connected to the adjusting sleeve 2, with the internal threads at both ends of the adjusting sleeve 2 rotating in opposite directions. The connecting member 1 can be made of a stainless steel screw. This embodiment enables bidirectional telescopic adjustment simply by rotating the adjusting sleeve 2, improving adjustment efficiency. The threaded connection also enhances adjustment precision, ensuring fine-tuning accuracy for the steel formwork 6 and improving the installation quality of the steel formwork structure.

[0027] In this embodiment, the adjustment member further includes a spring 3, which is disposed within the adjustment sleeve 2 and has its two ends connected to the corresponding connecting members 1. The maximum stretching length of the spring 3 is less than the length of the adjustment sleeve 2. This embodiment can prevent the two connecting members 1 from falling out of the adjustment sleeve 2 due to their distance from each other when the tie assembly is telescopically adjusted; when the two connecting members 1 are brought closer together to contract the tie assembly, the spring 3 can also prevent the two connecting members 1 from directly colliding, thereby providing a buffering effect, ensuring the service life of the connecting members 1, and thereby improving the service life of the tie assembly; typically, during the adjustment process of the steel formwork structure, the tie assembly is often used to contract the distance between the steel formworks 2. When the two connecting members 1 are respectively connected to the corresponding steel formworks 6, the spring 3 is stretched, and the adjustment sleeve 2 is rotated to move the two connecting members 1 toward each other. The stretched spring 3 promotes the adjustment through the reset force, making the operation more labor-saving.

[0028] In this embodiment, the tie assembly also includes an adjustment handle 4, which is connected to the adjustment member to facilitate operation. In this embodiment, the adjustment handle 4 is connected to the adjustment sleeve 2 to drive the adjustment sleeve 2, making the adjustment process more convenient and labor-saving. In this embodiment, the adjustment handle 4 is T-shaped for easy grip.

[0029] In this embodiment, the adjustment handle 4 is detachably connected to the adjustment member. The adjustment sleeve 2 is provided with an adjustment hole 21 for inserting the adjustment handle 4. The construction worker can choose to directly rotate the adjustment sleeve 2 or push the adjustment sleeve 2 with the adjustment handle 4 to drive its rotation, which is highly flexible and adaptable.

[0030] In this embodiment, each connecting member 1 is detachably connected to the corresponding steel template 6 to reuse the tie assembly. In this embodiment, the steel template 6 is provided with a card slot, and a card 5 that can be engaged with the card slot is provided at the end of the connecting member 1 away from the adjustment member to improve the stability of the adjustment process. The connection and disassembly of the connecting member 1 and the steel template 6 can be quickly achieved by engaging, ensuring the reuse of the tie assembly and saving costs. In this embodiment, the card slot is composed of a fixed slot 71 and a connecting slot 72 that are interconnected. The end of the connecting member 1 away from the connecting sleeve 2 passes through the connecting slot 72 and is connected to the card 5. The size of the fixed slot 71 is adapted to the card 5 and the width of the card 5 is greater than the width of the connecting slot 72 for locking. In this embodiment, the clip 5 can be inserted into the corresponding fixing groove 71 from top to bottom in the vertical direction. In other embodiments, the clip 5 can also be inserted into the fixing groove 71 in the horizontal direction and fixed by rotation. The clip 5 can be detachably installed in the slot, which is the existing technology and is not described separately in the present utility model. It can ensure the stable connection between the tie assembly and the steel formwork 2 on both sides, play a horizontal constraint role during the adjustment process, and can be quickly disassembled to reuse the tie assembly.

[0031] The specific usage process of this embodiment is as follows:

[0032] Before use, check whether all parts are complete and undamaged. At the same time, check whether there are obvious deformation, cracks or rust on the surface of the tie assembly and steel template 6 to ensure the quality of each part before installation so as not to affect the installation quality;

[0033] According to the structure and slot size of the steel template 6, select the tie assembly with the adapter 5 to install and fix it to the steel template 6. After the installation and connection is completed, ensure that the connecting member 1, that is, the stainless steel screw, can rotate and move smoothly;

[0034] According to actual needs, a T-shaped adjustment handle 4 is inserted into the adjustment hole 21 to drive the adjustment sleeve 2 to rotate. The adjustment sleeve 2 can also be directly rotated by hand to drive the stainless steel screws at both ends to move and fine-tune the spacing of the steel template 6. During the adjustment process, pay attention to observe the steel template 6 to avoid deformation or damage to the steel template 6 caused by excessive adjustment.

[0035] After the steel template 6 is adjusted to the desired position, check the installation of the steel template 6 again to ensure the installation quality;

[0036] After the concrete and other materials are poured and reach a certain strength, the tie assembly can be removed for reuse. Finally, the removed tie assembly should be cleaned and inspected. If there are damaged and worn parts, they should be repaired or replaced in time and finally stored for the next turnover.

[0037] In this embodiment, threaded connections enable high-precision adjustment of the steel formwork 6, effectively reducing construction errors and the resulting rework and repair costs, thereby improving construction quality, accelerating construction progress, and saving construction costs. The tie assembly, primarily made of stainless steel, can withstand significant tension and pressure and is not easily damaged during construction, ensuring its reliability. Furthermore, during the pouring process, it prevents deformation of the steel formwork 6 due to stress from the pouring material, thereby ensuring the quality of the finished product. The tie assembly in this embodiment features a simple structure, low cost, strong adaptability, high stability, convenient construction, adjustable size, and reusable design. This significantly contributes to accelerating construction progress, improving project quality, controlling risks during the pouring process, and saving on reinforcement material costs.

[0038] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
