Abstract
Description
Technical Field
[0001] This application relates to the field of arc-shaped doorway construction technology, specifically to a deformable steel formwork suitable for arc-shaped doorway structures. Background Technology
[0002] In the field of water conservancy engineering, various apertures and types of arc-shaped gates have been widely used as working gates for waterways, and their main dimensions have entered the ranks of the world's largest arc-shaped gates. In traditional construction processes, the construction of arc-shaped gate slots typically relies on fixed-shape templates, which cannot be flexibly adjusted to accommodate gate slots of different sizes or curvatures. This application of fixed templates not only increases costs, as each different gate slot design requires the fabrication of new templates, but also reduces construction flexibility and efficiency. Because the curve structure of arc-shaped gate slots varies at different elevations, standardized templates cannot meet the requirements. Construction teams have to use wooden templates, customizing and processing them on-site according to the specific curve shape of each pouring elevation. This practice not only increases the amount of construction materials used but also significantly increases labor costs. Workers need to invest more time and effort in the precise fabrication and installation of these custom templates. Furthermore, on-site processing has a certain constraint and impact on the overall construction progress, as the fabrication and installation of each template requires additional time, thus extending the overall project completion cycle.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.
[0028] like Figures 1-4 As shown, this application embodiment provides a deformable steel template suitable for arc-shaped doorway structures. The deformable steel template for arc-shaped doorway structures includes a plate 1 and an adjustment mechanism 2. Multiple plates 1 are arranged side by side, and adjacent plates 1 are connected by a lockable hinge 3. A connecting seat is connected to the plate 1. The adjustment mechanism 2 has a first connecting end 21 and a second connecting end 22. The first connecting end 21 and the second connecting end 22 are rotatably connected to the connecting seats on two adjacent plates 1, respectively. The adjustment mechanism 2 also has a driving component, which is connected to the first connecting end 21 and the second connecting end 22 to drive the first connecting end 21 to move closer to or away from the first connecting end 21, or drive the second connecting end 22 to move closer to or away from the first connecting end 21, or drive the first connecting end 21 and the second connecting end 22 to move closer to or away from each other.
[0029] In use, force can be applied directly to plate 1 to make adjacent plates 1 rotate relative to each other to adjust the angle of adjacent plates 1. When the difference between the included angle of adjacent plates 1 and the desired included angle is small, the included angle of adjacent plates 1 can be finely adjusted by the drive component to ensure the accuracy of the included angle of adjacent plates 1. After the included angle is adjusted, the relative rotation state of the two adjacent plates 1 can be locked by the lockable hinge 3. At the same time, the adjustment mechanism 2 can be used as the rotation support of adjacent plates 1 to ensure that adjacent plates 1 have good state stability.
[0030] The deformable steel formwork provided in this application is suitable for curved doorway structures. Two adjacent plates 1 are connected by a lockable hinge 3, allowing them to rotate relative to each other. This adapts to curved doorway structures with various curvatures and sizes. During adjustment, the two plates 1 can be rotated relative to each other by the drive component in the adjustment mechanism 2. By setting the motion precision of the drive component, the included angle between the adjacent plates 1 can be precisely adjusted, which is beneficial to improving construction quality. Compared to the use of custom-made wooden formwork for curved doorway construction in the prior art, this application is suitable for construction scenarios with multiple sizes and curvature requirements, reducing costs. Moreover, compared to custom-made wooden formwork, the overall construction process is simpler, effectively improving construction efficiency, shortening the construction cycle, and reducing the labor intensity of workers. In addition, compared to custom-made wooden formwork, this application has the advantage of being reusable, which helps reduce resource consumption, production costs, and environmental burden, achieving a dual optimization of economic and environmental benefits.
[0031] In this embodiment, plate 1 can typically be designed as a rectangular steel plate, and the wide sides of two adjacent plates 1 are connected by a lockable hinge 3.
[0032] In some optional embodiments, the lockable hinge 3 includes a first connector 31 and a second connector 32. The first connector 31 and the second connector 32 are respectively connected to two adjacent plates 1. The first connector 31 can be designed as two spaced-apart first lugs connected to the wide side of the plate 1. The second connector 32 can be designed as a second lug, the width of which is adapted to the spacing between the two first lugs. The second lug is connected to the wide side of the adjacent plate 1. The first connector 31 has a first pin hole, indicating that the two... The first ear seat has a first pin hole arranged coaxially, and the second connector 32 has a second pin hole. The first pin hole and the second pin hole are coaxially arranged and a rotating pin is coaxially inserted, which means that the second ear seat is located between the two first ear seats. The rotating pin passes through the first ear seat, the second ear seat and the first ear seat in sequence. The first connector 31 and / or the second connector 32 have a set hole, and a set screw is threaded in the set hole. Thus, by rotating the set screw, the end of the set screw is pressed against the rotating pin, thereby locking the adjacent plate 1.
[0033] In some alternative embodiments, the rotating pin has a plurality of circumferentially distributed positioning grooves 331, which are configured to fit into the set screw shaft hole.
[0034] In this embodiment, the positioning groove 331 and the set screw form mechanical interference, which can further improve the locking effect of the set screw and ensure the stability of the plate 1 after it is locked.
[0035] In some alternative embodiments, the opening of the positioning groove 331 has a chamfered structure.
[0036] In this embodiment, the chamfered structure allows the set screw to be smoothly guided into the positioning groove 331 during screwing, reducing stress concentration or damage that may occur due to the sharp angle contact between the screw and the groove. The chamfered structure not only improves the fit accuracy between the set screw and the positioning groove 331 but also enhances the convenience and reliability of operation. This optimization further improves the stability and durability of the template locking, ensuring the structural stability of the template during construction and reducing the risk of damage due to improper operation.
[0037] In some alternative embodiments, the positioning groove 331 is a conical circular groove.
[0038] In this embodiment, the tapered structure allows the set screw to engage more precisely with the positioning groove 331 when screwed in, and achieves a self-locking function through the contraction characteristics of the tapered groove. When the set screw is screwed into the tapered groove, its outer surface gradually fits against the inner wall of the tapered groove, thereby generating greater friction and clamping force, further enhancing the locking effect. This not only improves the reliability and stability of the template locking, but also reduces the risk of loosening caused by external forces, ensuring that the arc-shaped doorway steel template always maintains a precise shape and position during construction, thereby significantly improving construction quality and efficiency.
[0039] In some alternative embodiments, the drive component is configured as a telescopic component, with the first connection end 21 or the second connection end 22 connected to the telescopic end of the telescopic component.
[0040] In this embodiment, the telescopic component can directly drive the relative rotation or displacement between adjacent plates 1 through its telescopic movement, thereby achieving precise adjustment of the included angle or position of the plates 1. The use of the telescopic component not only improves the flexibility and accuracy of adjustment, but also simplifies the operation process, enabling construction personnel to complete the deformation adjustment of the template more efficiently, and further improving the construction efficiency and adaptability of the arc-shaped door channel steel template.
[0041] In some alternative embodiments, the drive assembly has two telescopic ends, which are respectively connected to the first connection end 21 and the second connection end 22.
[0042] In this embodiment, the two telescopic ends allow workers to adjust the position of both the first connecting end 21 and the second connecting end 22, providing high flexibility and improving operational convenience to a certain extent, thereby increasing construction efficiency.
[0043] In some optional embodiments, the drive assembly includes a base 23, a first connecting rod 24 and a second connecting rod 25. The base 23 has a first telescopic hole and a second telescopic hole arranged coaxially. The first connecting rod 24 and the second connecting rod 25 are threadedly connected to the first telescopic hole and the second telescopic hole, respectively.
[0044] In this embodiment, the first connecting rod 24 and the second connecting rod 25 achieve telescopic movement via threaded transmission. The threaded transmission structure has good self-locking properties. Once the positions of the first connecting rod 24 and the second connecting rod 25 are determined, no additional fixing structure is needed. The positioning of the first connecting rod 24 and the second connecting rod 25 can be achieved through the threaded engagement structure between them and the base 23, which improves operational convenience and construction efficiency. Simultaneously, the threaded transmission structure is infinitely adjustable, enabling precise adjustment of the included angle between adjacent plates 1, which helps ensure construction quality. In actual implementation, the drive assembly can be configured with readily available turnbuckles.
[0045] In some optional embodiments, the connector is provided with a plurality of connection holes for connecting the adjustment mechanism 2.
[0046] In this embodiment, the arrangement of multiple connecting holes enables the adjustment mechanism 2 to form different connection forms with the plate 1, which is suitable for various adjustment conditions. For example, in some implementation scenarios, it is necessary to finely adjust the included angle of adjacent plates 1. In this case, the adjustment mechanism 2 can be connected to two connecting holes with a larger distance between them on the adjacent plates 1. In some implementation scenarios, it is necessary to save space on the template. In this case, the adjustment mechanism 2 can be connected to two connecting holes with a smaller distance between them on the adjacent plates 1.
