[0002] The curved segment formwork is a temporary support structure used for the construction of structures with specific curvatures. It is commonly used in projects such as roads, railways, bridges, tunnels, etc., especially when concrete structures need to be constructed in a curved shape. The curved segment formwork can help construction workers accurately shape the curved contour of the concrete, ensuring that the geometric size and shape of the structure meet the design requirements. This formwork can be customized according to different engineering requirements to adapt to curved structures of different radii and angles.

[0003] After searching, the Chinese patent application number is: CN202210233278.8, which discloses an adjustable triangular support device for building formwork.

[0028] See also Figure 1-3 , the utility model provides a technical solution:

[0029] A curved arc template fastening device comprises: a base plate 1; a side plate 2 is integrally formed on one side of the base plate 1; a fastening mechanism is arranged on the side plate 2; a plurality of fastening mechanisms are installed on the side plate 2 from bottom to top, the fastening mechanism comprises a connecting plate 3 and a connecting seat 4, the connecting plate 3 is welded on the connecting seat 4, a slot 15 is arranged at the bottom of the connecting seat 4; a plurality of groups of threaded holes 8 are equidistantly distributed on the connecting plate 3, a fastening screw 9 is installed on the internal thread of the threaded hole 8, a handle 10 is welded on one end of the fastening screw 9, and a top block 11 is arranged at the other end of the fastening screw 9.

[0030] By arranging the side plate 2 on the bottom plate 1, arranging the fastening mechanism including the connecting plate 3 and the connecting seat 4 on the side plate 2, arranging multiple groups of fastening screws 9 on the connecting plate 3, arranging the handle 10 at one end of the fastening screw 9, and arranging the top block 11 at the other end of the fastening screw 9, in actual use, the bottom plate 1 is placed on one side of the arc-shaped template, the fastening mechanism is installed on the side plate 2, and the multiple groups of fastening screws 9 are adjusted according to the curvature of the arc-shaped template, and the handle 10 is rotated so that the top block 11 at the end of each group of fastening screws 9 on the connecting plate 3 is against the outer wall of the arc-shaped template, thereby providing good support and fastening for the arc-shaped template, avoiding displacement of the template during casting and solidification, and improving the stability and safety of the arc-shaped template casting;

[0031] At the same time, since multiple sets of fastening screws 9 are arranged on the connecting plate 3, the device can adapt the extension length of the fastening screws 9 according to the curvature of the curved template, so that the device can adapt to curved templates with different curvatures;

[0032] In general, the device has a simple structure and is easy to use. It can quickly, stably and reliably fasten the curved formwork to prevent the formwork from shifting or deforming during the pouring process. At the same time, it can also be flexibly adjusted according to formworks of different curvatures, and has high practicality and range of use.

[0033] Also, see Figure 2 :

[0034] The connection seat 4 in the bottom fastening mechanism is clamped on the side plate 2 through the slot 15, and the side plate 2 is fixed to the connection seat 4 by fixing screws. The connection plate 3 in the adjacent fastening mechanism is inserted into the slot 15, and the connection plate 3 is fixed to the connection seat 4 by fixing screws. The connection seat 4 is provided with a first connection hole 6, and the connection plate 3 is provided with a second connection hole 7. The first connection hole 6 corresponds to the second connection hole 7, and the side plate 2 is provided with a fixing hole 5, and the first connection hole 6 also corresponds to the fixing hole 5.

[0035] By providing a side plate 2 with a fixing hole 5, a connecting plate 3 with a first connecting hole 6, a connecting seat 4 with a second connecting hole 7, and a slot 15 being provided on the connecting seat 4, the lowest connecting seat 4 is connected to the side plate 2 by fixing screws, and adjacent fastening mechanisms are connected by fixing screws, so that the device can flexibly adjust the number of fastening mechanisms according to the height of the arc template, thereby further improving the practicality and application range of the device;

[0036] In addition, a threaded column 13 is provided at the end of the fastening screw 9, and a threaded groove 14 is provided on one side of the top block 11, and the top block 11 is threadedly mounted on the threaded column 13 through the threaded groove 14;

[0037] Such a design enables the top block 11 in the device to be installed and replaced quickly and conveniently. During long-term use, once a top block 11 is damaged, it can be replaced separately.

[0038] At the same time, the fastening screw 9 can be removed from the threaded hole 8 on the connecting plate 3 after removing the top block 11. During long-term use, once a fastening screw 9 is damaged, it can be replaced separately.

[0039] A rubber head 12 is also bonded to the end of the top block 11, which can play a certain anti-slip role after the top block 11 contacts the arc-shaped template for support and fastening.

[0040] For further information, see Figure 1 , 2 and Figure 4 :

[0041] The other side of the bottom plate 1 is provided with an inclined block 16, and an inclined positioning hole 17 is provided on the inclined surface of the inclined block 16. A positioning pin 18 is inserted into the positioning hole 17, and the lower end of the positioning pin 18 is set in a cone shape, and a limit block 19 is set at the upper end of the positioning pin 18.

[0042] By arranging an inclined block 16 on the base plate 1, an inclined positioning hole 17 is opened on the inclined surface of the inclined block 16. When in use, after the base plate 1 is placed on one side of the arc-shaped template, the positioning pin 18 is inserted into the positioning hole 17 until the limit block 19 abuts against the inclined surface. This design can play a good positioning role after the arc-shaped template is fastened and supported, so that the device will not be easily displaced, and the inclined design makes the grip of the positioning pin 18 stronger.

[0043] Also, see Figure 4 :

[0044] Ear seats 20 are symmetrically arranged on both sides of the inclined surface of the inclined block 16 . The ear seats 20 are arranged in an L shape. A baffle 21 is inserted between the two groups of ear seats 20 . When the positioning pin 18 is fully inserted into the positioning hole 17 , the baffle 21 just contacts the top of the limit block 19 .

[0045] By arranging ear seats 20 on the inclined surface, and slidingly inserting baffles 21 between the ear seats 20, after the positioning pin 18 is inserted into the positioning hole 17, the baffle 21 is inserted into the ear seat 20. Since the inclined surface has an inclined angle, one side of the baffle 21 will contact the bottom plate 1 after insertion, and the baffle 21 will not easily leave the ear seat 20. The baffle 21 can effectively prevent the positioning pin 18 from escaping from the positioning hole 17, further improving the positioning ability of the device, and having higher safety and stability. When the equipment needs to be disassembled, the baffle 21 can be pulled out to remove the positioning pin 18.

[0046] Among them, see Figure 1-4 The device has a detachable function between the connecting plate 3 and the fastening screw 9, between the fastening screw 9 and the top block 11, between adjacent fastening mechanisms, between the fastening mechanism and the side plate 2, between the positioning pin 18 and the inclined block 16, and between the baffle 21 and the ear seat 20, so that the device can be easily combined for use and disassembled for storage, and is also convenient for transporting the equipment, further improving the practicality of the device.
