Description

Technical Field

[0001] This utility model relates to the field of road construction, and in particular to a template for road curve construction. Background Technology

[0002] In highway construction, the selection of pavement formwork is crucial to construction quality. Most existing formwork is straight-lined. When pouring concrete for curves using straight formwork, the formwork doesn't match the curve's shape, requiring construction workers to spend more time and effort cutting, splicing, and adjusting to ensure a proper fit. This increases construction difficulty and may affect efficiency and quality. Furthermore, existing curve formwork has fixed dimensions and shapes, making it difficult to adjust to actual needs. Complex pavements may have varying curvatures and widths, and existing curve formwork is difficult to install and adjust, limiting its flexibility and applicability, making it challenging to pour concrete for curves with different curvature and width requirements. Therefore, we propose a new formwork for pavement curve construction to solve these problems. Utility Model Content

[0003] This utility model provides a template for road curve construction, which solves the problems of spending more time and effort on cutting, splicing and adjusting when pouring curves with straight templates, which affects construction efficiency; and the difficulty in installing and adjusting curve templates, which limits the flexibility and applicability of templates.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a template for road curve construction, including multiple first mounting seats, a second mounting seat is provided on one side of the first mounting seat, a sliding plate is provided between the first mounting seat and the second mounting seat, a first mounting seat is provided between two adjacent first mounting seats, an inner template is provided between two adjacent second mounting seats, and multiple fastening devices are provided on the outer template and the inner template. The first mounting seat includes two rotating seats, and a rotating ring is provided on the rotating seat.

[0005] In a preferred embodiment, the first mounting base includes a mounting plate with two rotating seats, an arc-shaped plate on the rotating ring, a slot on the arc-shaped plate, and a rotating hole on the top of the mounting plate.

[0006] In the preferred embodiment, the second mounting base has the same structure as the first mounting base. The top of the second mounting base is provided with a connecting box, the connecting box is provided with a groove, and the top of the groove is provided with a first threaded hole.

[0007] In the preferred embodiment, one end of the slide plate is provided with a column, which abuts against the rotating hole. The slide plate is provided with multiple through holes, and one end of the slide plate abuts against the groove. The first bolt passes through the first threaded hole and the through hole.

[0008] In the preferred embodiment, the outer template includes an arc-shaped template with arc-shaped inserts at both ends and multiple second threaded holes on the arc-shaped template, into which the arc-shaped inserts are inserted.

[0009] In the preferred embodiment, the inner template structure is the same as the outer template structure.

[0010] In a preferred embodiment, the fastening device includes a buckle, a connecting rod, and two rotating rings. The bottom ring is connected to the buckle via the connecting rod, and the rotating rings abut against a second bolt. The second bolt passes through a second threaded hole, and the buckle is provided with a rotating fixing pin that is inserted into the ground.

[0011] The beneficial effects of this utility model are as follows: When it is necessary to pour the road surface on a curve, the first mounting seat and the second mounting seat are installed, the curvature of the outer template and the inner template is selected according to the designed road surface curvature, the second mounting seat and the first mounting seat are positioned according to the designed road surface width, the first bolt is removed so that the second mounting seat can slide on the slide plate, the distance between the second mounting seat and the first mounting seat is determined, and the first bolt is installed so that the overall structure can adapt to curved road surfaces of different widths.

[0012] Position adjacent outer formworks according to their curvature and length. Rotate the swivel on the first mounting base to allow the arc-shaped inserts at both ends of the outer formwork to be inserted into two different slots, thus installing the outer formwork. The second mounting base and slide plate can rotate relative to the first mounting base to adjust the distance between adjacent second mounting bases. Simultaneously, rotate the swivel on the second mounting base to allow the arc-shaped inserts at both ends of the inner formwork to be inserted into two different slots, thus installing the inner formwork. The overall structure can adapt to outer and inner formworks of different curvatures and lengths, and can also adapt to road surface structures of different widths. Its strong adaptability and flexibility allow for the casting of curves with different curvature and width requirements. This avoids the need for more time and effort in cutting, splicing, and adjusting when casting curves using straight formwork, which affects construction efficiency; it also avoids the difficulty in installing and adjusting curved formwork, making it highly valuable for widespread application.

Detailed Implementation

[0021] Example 1:

[0022] like Figure 1-6 In this structure, a template for road curve construction includes multiple first mounting seats 1. A second mounting seat 2 is located on one side of each first mounting seat 1. A sliding plate 3 is located between the first mounting seats 1 and the second mounting seats 2. A first mounting seat 1 is positioned between two adjacent first mounting seats 1. An inner template 5 is positioned between two adjacent second mounting seats 2. Multiple fastening devices 6 are provided on the outer template 4 and the inner template 5. Each first mounting seat 1 includes two rotating seats 102, each with a rotating ring 103. With this structure, when pouring concrete for a road curve, the first mounting seats 1 and second mounting seats 2 are installed. The curvature of the outer template 4 and inner template 5 is selected according to the designed road curvature. The second mounting seats 2 and first mounting seats 1 are positioned according to the designed road width. The first bolt 7 is removed to allow the second mounting seat 2 to slide on the sliding plate 3. The distance between the second mounting seat 2 and the first mounting seat 1 is determined. The first bolt 7 is then installed again, allowing the overall structure to adapt to road curves of different widths.

[0023] Position the two adjacent outer templates 4 according to their curvature and length. Rotate the rotating ring 103 on the first mounting base 1 so that the arc-shaped inserts 402 at both ends of the outer template 4 can be inserted into two different slots 105 to install the outer template 4. The second mounting base 2 and the sliding plate 3 can rotate relative to the first mounting base 1 so that the distance between the two adjacent second mounting bases 2 can be adjusted. At the same time, rotate the rotating ring on the second mounting base 2 so that the arc-shaped inserts at both ends of the inner template 5 can be inserted into two different slots 105 to install the inner template 5. The overall structure can adapt to outer templates 4 and inner templates 5 with different curvatures and lengths. At the same time, the overall structure can adapt to road surface structures with different widths. The overall structure has strong adaptability and good flexibility and applicability, enabling the casting of curves with different curvature and width requirements. It avoids the phenomenon of spending more time and effort on cutting, splicing and adjusting when casting curves with straight templates, which affects construction efficiency; it also avoids the phenomenon of difficult installation and adjustment of curved templates. It speeds up construction efficiency and reduces construction costs.

[0024] In a preferred embodiment, the first mounting base 1 includes a mounting plate 101, on which two rotating seats 102 are provided. A curved plate 104 is provided on a rotating ring 103, and a slot 105 is provided on the curved plate 104. A rotating hole 106 is provided at the top of the mounting plate 101. With this structure,

[0025] In the preferred embodiment, the second mounting base 2 has the same structure as the first mounting base 1. The top of the second mounting base 2 is provided with a connecting box 201, and the connecting box 201 has a groove 203. The top of the groove 203 has a first threaded hole 202. With this structure, the column at one end of the sliding plate 3 abuts against the rotating hole 106, allowing the sliding plate 3 to rotate relative to the first mounting base 1, and allowing the second mounting base 2 to rotate relative to the first mounting base 1. This allows the overall structure to adapt to inner templates 5 of different lengths, and the rotating ring 103 of the second mounting base 2 can rotate, allowing the overall structure to adapt to inner templates 5 of different curvatures.

[0026] The two adjacent first mounting seats 1 can adjust their installation positions so that the overall structure can adapt to the first mounting seats 1 at different distances. The rotating ring 103 of the first mounting seat 1 can rotate so that the overall structure can adapt to the outer template 4 with different curvatures.

[0027] In a preferred embodiment, the slide plate 3 has a column at one end, which abuts against the rotating hole 106. The slide plate 3 has multiple through holes 301, and one end of the slide plate 3 abuts against the groove 203. The first bolt 7 passes through the first threaded hole 202 and the through hole 301. With this structure, the first bolt 7 is used to adjust the position between the first mounting base 1 and the second mounting base 2.

[0028] In a preferred embodiment, the outer template 4 includes an arc-shaped template 401, with arc-shaped inserts 402 at both ends. The arc-shaped template 401 has multiple second threaded holes 403, and the arc-shaped inserts 402 are inserted into slots 105. With this structure, the installation positions of two adjacent first mounting seats 1 can be adjusted so that the overall structure can adapt to first mounting seats 1 at different distances. The rotating ring 103 of the first mounting seat 1 can rotate so that the overall structure can adapt to outer templates 4 with different curvatures.

[0029] In the preferred embodiment, the inner formwork 5 has the same structure as the outer formwork 4. With this structure, the concrete demolding surfaces of the inner formwork 5 and outer formwork 4 face each other, and concrete is poured between the inner formwork 5 and outer formwork 4. One end of the sliding plate 3 rests against the rotating hole 106, allowing the sliding plate 3 to rotate relative to the first mounting base 1, and allowing the second mounting base 2 to rotate relative to the first mounting base 1. This allows the overall structure to adapt to inner formwork 5s of different lengths. The rotating ring 103 of the second mounting base 2 can rotate, allowing the overall structure to adapt to inner formwork 5s of different curvatures.

[0030] In the preferred embodiment, the fastening device 6 includes a retaining ring 603, a connecting rod 602, and two rotating rings 601. The bottom ring 601 is connected to the retaining ring 603 via the connecting rod 602. The rotating ring 601 abuts against the second bolt 8, which passes through the second threaded hole 403. The retaining ring 603 is provided with a rotating fixing pin 604, which is inserted into the ground. With this structure, the fixing pin 604 is inserted into the ground, making the overall structure more stable. The two rotating rings 601 can rotate relative to the second bolt 8, allowing the fastening device 6 to be retracted and extended on the outer template 4 or inner template 5. Rotating the second bolt 8 allows for disassembly of the fastening device 6 from the outer template 4 or inner template 5, enabling the fastening device 6 to be reused multiple times, saving materials, and providing quick disassembly and installation, thus accelerating construction efficiency.
