Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figures 2-3As shown, this embodiment provides a formwork device for cast-in-place concrete strips at a rapid flow channel. The formwork device for cast-in-place concrete strips at a rapid flow channel includes a formwork assembly and a clamping assembly.

[0036] The template assembly includes two arc-shaped templates 101 that are positioned opposite each other and spaced apart, with the arc-shaped space between the two arc-shaped templates 101 used for pouring concrete.

[0037] like Figures 2-3 As shown, the clamping assembly has at least two components, including a horizontal bar 201 and two vertical bars 202. The horizontal bar 201 has at least three vertical holes 203 spaced apart. The horizontal bar 201 is located above the arc-shaped template 101 and spans across the two arc-shaped templates 101 in opposite directions. The two vertical bars 202 are respectively inserted into different vertical holes 203 and abut against the outer walls of the two arc-shaped templates 101.

[0038] like Figure 1 and Figure 2 As shown, during construction, two arc-shaped templates 101 are placed opposite each other at the junction of the road surface 1 and the trough 3, with one end of the arc-shaped template 101 abutting against the side wall of the shoulder 2 and the other end abutting against the side wall of the trough shoulder 4, thus forming an arc-shaped space for pouring concrete together with the shoulder 2 and the trough shoulder 4, facilitating concrete pouring within the arc-shaped space. Then, a horizontal bar 201 is placed above the arc-shaped template 101. Based on the spacing of the arc-shaped templates 101, different vertical holes 203 are selected on the horizontal bar 201, and two vertical bars 202 are inserted into the vertical holes 203 respectively, so that the two vertical bars 202 are pressed against the outer side walls of the two arc-shaped templates 101 respectively. The vertical bars 202 apply pressure to the arc-shaped template 101 within the arc-shaped space, thereby fixing the arc-shaped template 101.

[0039] The design, featuring at least two clamping components spanning two curved templates 101 via a horizontal bar 201 and vertical bars 202 inserted into different vertical holes 203 on the horizontal bar 201 and pressed against the outer wall of the curved template 101, is simple and convenient to operate. Construction workers can quickly select appropriate vertical holes 203 to insert into the vertical bars 202 based on the spacing of the curved templates 101, thus fixing the curved templates 101 without cumbersome fixing procedures, shortening construction time and improving the construction efficiency of the cast-in-place trough. The vertical holes 203 can be flexibly selected to insert into the vertical bars 202 according to the spacing requirements of the curved templates 101 in different construction scenarios, making it suitable for the construction of cast-in-place troughs of various sizes and specifications, thus improving the versatility of the template device. Two relatively spaced arc-shaped templates 101 are used, whose shapes match the curves at the junction of the road surface and the trough. Compared with conventional wooden templates, there is no need for complex on-site cutting and splicing. They can be quickly positioned and placed in the predetermined position, with one end attached to the side wall of the road shoulder and the other end attached to the side wall of the trough shoulder. This can significantly reduce the template layout time and speed up the construction progress. It can also directly form a regular arc-shaped space with the road shoulder and the trough shoulder, thereby improving the appearance quality of the concrete strip.

[0040] like Figures 2-3 As shown, optionally, each arc-shaped template 101 is provided with a vertical insertion hole, and each vertical rod 202 is inserted into the corresponding vertical insertion hole. The insertion of each vertical rod 202 into the corresponding vertical insertion hole provides precise positioning between the vertical rod 202 and the arc-shaped template 101. Compared to relying solely on the vertical rod 202 pressing against the outer wall of the arc-shaped template 101, the cooperation between the vertical insertion hole and the vertical rod 202 further restricts the relative displacement between the vertical rod 202 and the arc-shaped template 101, ensuring that the connection position between the vertical rod 202 and the arc-shaped template 101 is fixed and accurate. This results in more precise positioning of the two arc-shaped templates 101 after installation, ensuring the stability of the arc-shaped space used for concrete pouring, improving the forming accuracy of the concrete strip, making the shape and size of the concrete strip more in line with design requirements, and achieving better appearance quality.

[0041] like Figures 2-3 As shown, optionally, each arc-shaped template 101 has a first arc-shaped plate 102 and a second arc-shaped plate 103 oppositely arranged on its outer side wall. The first arc-shaped plate 102 and the second arc-shaped plate 103 are connected by fasteners 104, forming a vertical insertion hole between them. The distance between the first arc-shaped plate 102 and the second arc-shaped plate 103 can be flexibly adjusted by adjusting the tightening degree of the fasteners 104 according to actual construction needs, thereby changing the size of the vertical insertion hole. This facilitates the insertion of the vertical rod 202 when the diameter of the vertical insertion hole is large, and also facilitates reducing the diameter of the vertical insertion hole after the vertical rod 202 is inserted to tightly hold the vertical rod 202, improving stability.

[0042] Optionally, the first arc-shaped plate 102 has a first through hole, and the second arc-shaped plate 103 has a second through hole. The fastener 104 includes a bolt and a nut. The bolt passes through the first and second through holes and is connected to the nut. This bolt and nut connection method is very convenient in construction. Construction workers only need simple tools, such as wrenches, to easily pass the bolt through the through holes and tighten the nut to complete the connection between the first arc-shaped plate 102 and the second arc-shaped plate 103. When disassembly is required, the two arc-shaped plates can be separated by turning the nut in the opposite direction, facilitating adjustment of the vertical insertion hole, saving construction time, improving construction efficiency, and reducing construction difficulty.

[0043] like Figures 2-3 As shown, optionally, multiple fasteners 104 are spaced apart along the depth direction of the vertical insertion hole. The multiple fasteners 104 spaced apart along the depth direction of the vertical insertion hole ensure that the first arc-shaped plate 102 and the second arc-shaped plate 103 are tightly connected throughout the entire depth range of the vertical insertion hole. During concrete pouring, when the formwork is subjected to external forces such as lateral pressure from the concrete, these evenly distributed fasteners 104 can evenly distribute the stress across the entire vertical insertion hole structure, preventing stress concentration in a localized area. This effectively prevents the first arc-shaped plate 102 and the second arc-shaped plate 103 from separating or deforming due to excessive localized stress, significantly enhancing the stability and overall strength of the vertical insertion hole.

[0044] like Figures 2-3 As shown, optionally, the clamping assembly also includes limiting components corresponding one-to-one with the vertical rods 202. The limiting components include an upper limiting member 204 and a lower limiting member 205, both detachably mounted on the vertical rods 202. The upper limiting member 204 and the lower limiting member 205 respectively abut against the vertical side walls of the horizontal rod 201. The upper limiting member 204 and the lower limiting member 205 abut against the side walls of the horizontal rod 201, forming a reliable limit on the vertical rods 202, effectively preventing the vertical rods 202 from accidentally sliding within the vertical holes 203 of the horizontal rods 201. During concrete pouring, the formwork is subjected to various external forces, such as the impact of concrete and vibration during compaction. If the vertical rods 202 slide, it may cause the curved formwork 101 to shift, thus affecting the concrete forming. In other embodiments, the limiting components may not be provided; the horizontal rods 201 can simply be placed on the two curved formworks 101.

[0045] like Figures 2-3As shown, optionally, the upper limit member 204 is threadedly connected to the vertical rod 202, and the lower limit member 205 is threadedly connected to the vertical rod 202. Threaded connections have inherent self-locking properties and good linear adjustment characteristics. With each rotation of a certain angle, the distance that the upper limit member 204 or the lower limit member 205 moves on the vertical rod 202 is relatively fixed and precisely controllable. This allows construction personnel to finely adjust the relative positions of the vertical rod 202 and the horizontal rod 201 according to actual construction needs, and achieve self-locking after adjustment. In this embodiment, both the upper limit member 204 and the lower limit member 205 can be nuts.

[0046] Optionally, the vertical rod 202 includes a connected smooth section and a threaded section. The upper limit member 204 and / or the lower limit member 205 are threadedly connected to the threaded section, and only the smooth section contacts the arc-shaped template 101. This minimal contact between the smooth section and the arc-shaped template 101 avoids scratching the template during installation and use caused by the rough surface of the threaded section, facilitating the installation of the vertical rod 202 and the arc-shaped template 101 and extending its service life. The good contact between the smooth section and the arc-shaped template 101 ensures even pressure distribution on the vertical rod 202, resulting in more uniform stress on the arc-shaped template 101 and enhancing the overall stability of the template device.

[0047] Optionally, a rubber buffer layer is provided on the lower end face of the curved template 101. The rubber buffer layer has a certain elasticity and can fill the tiny gaps between the lower end face of the curved template 101 and the ground. Furthermore, the rubber buffer layer can also cushion the impact on the ground during the installation of the curved template 101, preventing damage to the ground and the formation of gaps. The rubber buffer layer effectively prevents grout leakage, ensuring that the concrete solidifies within the specified space and ensuring the quality of the concrete strip. In this embodiment, the rubber buffer layer is adhesively bonded to the lower end face of the curved template 101.

[0048] like Figures 2-3 As shown, optionally, only two clamping assemblies are provided, with the two clamping assemblies respectively located at both ends of the arc-shaped template 101 along the arc length direction. Having only two clamping assemblies significantly reduces the number of parts. This makes the template device structure simpler, reduces the workload of processing and assembly, and improves work efficiency.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
