Description

Technical Field

[0001] This utility model relates to the field of concrete paving technology, specifically to a template for permeable concrete paving. Background Technology

[0002] Permeable concrete, also known as porous concrete, permeable pavement, or ecological permeable concrete, is a special type of concrete with high permeability. It uses a special mix design and manufacturing process to create a large number of interconnected pores inside the concrete. Using permeable concrete to pave roads enables the roads to have excellent water permeability.

[0003] During the paving process, formwork is used to support both sides of the road to ensure its shape and size. However, the current formwork is not well connected to the roadbed. When the road roller compacts the concrete laid inside the formwork, the concrete exerts an outward squeezing force on the formwork, causing it to tilt or even overturn, making it difficult to guarantee the shape and size of the concrete road. Summary of the Invention

[0004] This invention addresses the problem of formwork tilting due to pressure on both sides during concrete road paving by providing a permeable concrete paving template that improves the connection between the template and the roadbed, prevents the template from tipping over, and ensures the shape and size of the concrete road paving.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A permeable concrete paving template includes a template with multiple anchor rods on its bottom surface. It also includes support members spaced from front to back at the right end of the template. Each support member includes a vertical pole, a fixing cylinder, and a limiting member. The vertical pole is vertically fixed to the right end of the template. A fixing cylinder is located on the lower right side of the vertical pole, with its closed end facing the vertical pole and its other end open. Multiple anchor plates are provided on the outer bottom surface of the fixing cylinder. The limiting member includes a U-shaped plate, a connecting plate, and pull ropes. The left end of the U-shaped plate slides into the fixing cylinder and is connected to the closed end of the fixing cylinder via an elastic band. The right end of the U-shaped plate extends out of the fixing cylinder. The left end of the connecting plate is hinged to the upper part of the vertical pole, and the right end is hinged to the right end of the U-shaped plate. Multiple pull ropes are spaced apart on the bottom surface of the connecting plate. The lower end of each pull rope movably passes through the top plate of the fixing cylinder and connects to the inner bottom surface of the U-shaped plate.

[0007] Furthermore, the template includes a vertical plate and a horizontal plate. The upper and lower ends of the right side surface of the vertical plate are connected to the horizontal plate. The right ends of the two horizontal plates are connected to the uprights on the support. Each anchor is fixed to the bottom surface of the lower horizontal plate.

[0008] Furthermore, the bottom surface of the fixed cylinder is flush with the bottom surface of the lower horizontal plate, and the front and rear outer sides of each fixed cylinder are connected to the right end of the lower horizontal plate of the template via connecting rods.

[0009] Furthermore, the anchor plate is a rectangular plate, the upper end of the anchor plate is fixedly connected to the outer bottom surface of the fixing cylinder, and the lower end of the anchor plate is connected to an isosceles triangular prism with the tip pointing downwards. Multiple anchor plates on the same fixing cylinder are spaced apart from left to right and are parallel to each other.

[0010] Furthermore, the outer surface of each U-shaped plate slides in contact with the inner wall of the fixed cylinder.

[0011] Furthermore, an n-shaped plate is fixed to the upper right side of each of the uprights. Each n-shaped plate corresponds to a connecting plate on the support member. The left end of each connecting plate extends into the corresponding n-shaped plate. The front and rear sides of the left end of the connecting plate are rotatably connected to the front and rear side plates of the n-shaped plate via a rotating rod. The right end of each connecting plate extends into the corresponding U-shaped plate. The front and rear sides of the right end of the connecting plate are rotatably connected to the front and rear side plates of the U-shaped plate via a rotating rod.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] The connecting plate on each support member of this utility model enables the formwork to support and limit the concrete. After the formwork is subjected to the force of the concrete, the force is transmitted to the connecting plate. The force on the connecting plate is converted into a tension force on the connecting plate through the U-shaped plate and the pull rope. The force on the connecting plate is also converted into the potential energy of the elastic band, which prevents the connecting plate from tilting excessively, so that the connecting plate can continue to support the formwork, reduce the degree of tilt of the formwork after being subjected to the force of the concrete, and thus ensure the stable support of the formwork for the concrete.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1-3 As shown, a permeable concrete paving template includes a template 1. The bottom surface of the template 1 is provided with multiple anchor rods 2, spaced apart from front to back. Each anchor rod 2 is a round rod, and its lower end is connected to a cone 3. The template also includes support members spaced apart from front to back on the right end of the template 1. Each support member includes a vertical pole 4, a fixing cylinder 5, and a limiting member. The vertical pole 4 is a rectangular rod, vertically fixed to the right end of the template 1. A fixing cylinder 5 is located on the lower right side of the vertical pole 4. The fixing cylinder 5 is a rectangular cylinder, with its closed end facing the vertical pole 4 and its other end open. The bottom surface is provided with multiple anchor plates 6; the limiting component includes a U-shaped plate 7, a connecting plate 8 and a pull rope 9. The left, right and upper ends of the U-shaped plate 7 are open. The left end of the U-shaped plate 7 slides into the fixed cylinder 5 and is connected to the closed end of the fixed cylinder 5 via an elastic band 10. The elastic band 10 is a rectangular band made of elastic rubber. The right end of the U-shaped plate 7 extends out of the fixed cylinder 5. The connecting plate 8 is a rectangular plate. The left end of the connecting plate 8 is hinged to the upper part of the upright 4, and the right end is hinged to the right end of the U-shaped plate 7. Multiple pull ropes 9 are connected at intervals on the bottom surface of the connecting plate 8. The lower end of each pull rope 9 movably passes through the top plate of the fixed cylinder 5 and connects to the inner bottom surface of the U-shaped plate 7.

[0020] The template 1 includes a vertical plate 1a and a horizontal plate 1b. The upper and lower ends of the right side surface of the vertical plate 1a are connected to the horizontal plate 1b. The two horizontal plates and the vertical plate are integrally formed. The right ends of the two horizontal plates 1b are connected to the uprights 4 on the support. Each anchor rod 2 is fixed to the bottom surface of the lower horizontal plate 1b.

[0021] The bottom surface of the fixed cylinder is flush with the bottom surface of the lower horizontal plate. The front and rear outer sides of each fixed cylinder 5 are connected to the right end of the lower horizontal plate 1b of the template 1 via a connecting rod 15. The connecting rod can realize the connection between the fixed cylinder and the template, thereby increasing the overall stability of this utility model.

[0022] The anchor plate 6 is a rectangular plate. The upper end of the anchor plate 6 is fixedly connected to the outer bottom surface of the fixing cylinder 5. The lower end of the anchor plate is connected to an isosceles triangular prism 11 with the tip pointing downward. Multiple anchor plates 6 on the same fixing cylinder 5 are spaced apart from left to right and are parallel to each other.

[0023] The outer side of each U-shaped plate 7 slides in contact with the inner wall of the fixed cylinder 5.

[0024] Each of the uprights 4 has an n-shaped plate 12 fixed on the upper right side. The upper and lower ends and the right end of the n-shaped plate 12 are open. Each n-shaped plate 12 corresponds to a connecting plate 8 on the support member. The left end of each connecting plate 8 extends into the corresponding n-shaped plate 12. The front and rear sides of the left end of the connecting plate 8 are rotatably connected to the front and rear side plates of the n-shaped plate 12 via a rotating rod 13. The right end of each connecting plate 8 extends into the corresponding U-shaped plate 7. The front and rear sides of the right end of the connecting plate 8 are rotatably connected to the front and rear side plates of the U-shaped plate 7 via a rotating rod 2 14.

[0025] When in use, this utility model is installed on both sides of the concrete to be paved. The anchor rod 2 and the anchor plate 6 extend into the roadbed, and the side of the vertical plate 1a on the template 1 without the upright 4 faces the road, so that this utility model can be fixed. The connecting plate 8 on each support can enable the template 1 to support and limit the concrete.

[0026] When the road roller compacts and paves concrete, the vertical plate 1a of the formwork 1 can support the concrete. If the compacted concrete exerts a rightward force on the right side of the formwork 1, the upper end of the vertical plate 1a of the formwork 1 tends to tilt to the right, and the uprights 4 on the support tend to tilt to the right along with the formwork 1. The uprights 4 exert a rightward downward force on the left end of the connecting plate 8, and the right end of the connecting plate 8 exerts a rightward force on the U-shaped plate 7. When the U-shaped plate 7 is subjected to a rightward force, it will be converted into the potential energy of the elastic band 10 after stretching. When the U-shaped plate 7 is subjected to a rightward force, it can be converted into a downward force on the connecting plate 8 through multiple ropes 9, thereby offsetting part of the downward force on the connecting plate 8, ensuring the support of the uprights 4 by the connecting plate 8, thereby offsetting the rightward force on the vertical plate 1a of the formwork 1, reducing the tilt of the formwork 1 after being subjected to the force of the concrete, and thus ensuring the stable support of the formwork 1 for the concrete.

[0027] Similarly, after the formwork 1 on the left is subjected to a force from the concrete to the left, the support can reduce the degree of tilt of the formwork 1 after being subjected to the force from the concrete, thereby ensuring the stable support of the formwork 1 to the concrete.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
