Technical Field

[0001] This utility model is a mold for pouring concrete for the backrest of curved curb stones, belonging to the field of road engineering. Background Technology

[0002] After the curbstone of the road project is completed, the backrest needs to be poured. In the past, straight sections were poured using manual formwork, while curved sections could only be poured using fair-faced concrete formwork because there was no corresponding formwork, which affected the appearance. In the past, curved backrests were generally larger at the bottom than at the top due to the lack of formwork, forming a trapezoid and wasting a lot of concrete. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mold for pouring concrete for curved curb backrests, so as to solve the problems mentioned in the background art. This utility model improves work efficiency, fills the gap of the previous inability to standardize the pouring of curved backrests, and saves concrete.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold for pouring concrete for the backrest of a curved curbstone, comprising a rectangular tube, both ends of which are connected and fixed with end tubes. A gripping rod is rotatably mounted on the upper surface of one of the end tubes. Vertical rollers for fitting against the side of the curved curbstone are installed at both ends of the rectangular tube. A transverse roller for overlapping the upper surface of the curved curbstone is provided on the side of each of the two vertical rollers near the end tubes. One end of the transverse roller is connected to the rectangular tube. A U-shaped frame is connected and fixed at the middle of the upper surface of the rectangular tube. A transverse tube is inserted into the space formed by the U-shaped frame and the rectangular tube. A rectangular sleeve is connected and fixed at the end of the transverse tube away from the rectangular tube. A vertical tube is inserted into the rectangular sleeve. An arc-shaped template is installed at the lower end of the vertical tube. A first positioning screw for limiting the relative position of the transverse tube and the U-shaped frame is threadedly connected to the upper surface of the U-shaped frame. Two second positioning screws for limiting the relative position of the rectangular sleeve and the vertical tube are threadedly connected to the side of the rectangular sleeve away from the rectangular tube.

[0005] Furthermore, a first threaded sleeve is fixedly connected to the upper surface of the U-shaped frame, and a first positioning screw is threadedly connected inside the first threaded sleeve. One end of the first positioning screw passes through the U-shaped frame and contacts the horizontal tube. Two second threaded sleeves are installed on the side of the rectangular sleeve opposite to the rectangular tube. The second positioning screw is threadedly connected inside the second threaded sleeve, and one end of the second positioning screw passes through the rectangular sleeve and contacts the vertical tube.

[0006] Furthermore, two lugs are installed on the upper surface of each of the two end tubes, and one end of the gripping rod is rotatably mounted between the two lugs on one end tube by a connecting screw and a connecting nut.

[0007] Furthermore, both ends of the rectangular tube are connected and fixed with support tubes, which are arranged perpendicular to each other.

[0008] Furthermore, vertical holes are provided at both ends of the rectangular tube, and a vertical stud is rotatably installed on the upper end of the vertical roller. The vertical stud passes through the vertical hole, and a vertical nut that is threadedly connected to the vertical stud is provided on the upper and lower sides of the vertical hole.

[0009] Furthermore, a connecting lug is fixedly connected to the lower surface of the rectangular tube near the end tube, and a horizontal stud is rotatably installed at one end of the transverse roller. The horizontal stud passes through the connecting lug, and both sides of the connecting lug are threaded with horizontal nuts that are threaded to the horizontal stud.

[0010] Furthermore, the lower end of the vertical pipe is connected and fixed with multiple connecting blocks, which are connected and fixed to the arc-shaped template.

[0011] The beneficial effects of this utility model are:

[0012] 1. Adjust the position of the horizontal tube along the U-shaped frame as needed. At this time, the distance between the curved template and the rectangular tube changes. Adjust the position of the vertical tube along the rectangular sleeve to change the height of the curved template. When the position of the curved template on the back of the curved curb meets the requirements, use the first positioning screw to limit the relative position of the U-shaped frame and the horizontal tube, and use the second positioning screw to limit the relative position of the vertical tube and the rectangular sleeve, thereby limiting the position of the curved template. At this time, the horizontal roller overlaps the upper surface of the curved curb, and the vertical roller is attached to the outer side of the curved curb, so as to facilitate movement along the curved curb. Add concrete in the space between the back of the curved curb and the curved template, so as not to make the concrete poured on the back of the curved curb have a structure that is wider at the bottom and narrower at the top.

[0013] 2. The concrete mold for the curb backrest is simple and convenient to operate, improves work efficiency, and allows for a more comprehensive pouring range. It fills the gap in the previous inability to standardize the pouring of curved backrests. Backrest construction reduces manpower input, saves concrete, eliminates the need for material turnover, has low equipment costs, reduces cost input and material waste, and ensures high safety, high aesthetic appeal of the finished product, and high quality compliance.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a mold for pouring concrete for curved edge stone backrests, including a rectangular tube 1, with end tubes 8 fixedly connected to both ends of the rectangular tube 1, and support tubes 7 fixedly connected to both ends of the rectangular tube 1. The support tubes 7 are arranged perpendicular to the rectangular tube 1. Two lugs 19 are installed on the upper surface of each of the two end tubes 8, so that one end of the gripping rod 14 is rotatably installed between the two lugs 19 on one end tube 8 by connecting screws and connecting nuts, which facilitates the installation of the gripping rod 14 on one of the two end tubes 8.

[0022] See Figures 1-4Both ends of the rectangular tube 1 are equipped with vertical rollers 5 for fitting against the side of the curved curbstone. Vertical holes are opened at both ends of the rectangular tube 1. A vertical stud 17 is rotatably installed on the upper end of the vertical roller 5. The vertical stud 17 passes through the vertical hole. Vertical nuts 18 are provided on the upper and lower sides of the vertical hole and are threaded to the vertical stud 17. The vertical nuts 18 and the vertical stud 17 cooperate with each other to restrict the relative position of the vertical roller 5 and the rectangular tube 1. A transverse roller 6 is provided on the side of each vertical roller 5 near the end tube 8 for overlapping the upper surface of the curved curbstone. A connecting lug 16 is fixedly connected to the lower surface of the rectangular tube 1 near the end tube 8. A horizontal stud 22 is rotatably installed on one end of the transverse roller 6 and passes through the connecting lug 16. Horizontal nuts 15 are threaded to both sides of the connecting lug 16 and are threaded to the horizontal stud 22. The horizontal nuts 15 and the horizontal stud 22 cooperate with each other to complete the assembly of the transverse roller 6 and the rectangular tube 1.

[0023] See Figures 1-4 A U-shaped frame 4 is fixedly connected to the middle of the upper surface of the rectangular tube 1. A horizontal tube 3 is inserted into the space formed by the U-shaped frame 4 and the rectangular tube 1. A rectangular sleeve 12 is fixedly connected to the end of the horizontal tube 3 away from the rectangular tube 1. A vertical tube 11 is inserted into the rectangular sleeve 12. Multiple connecting blocks 10 installed at the lower end of the vertical tube 11 are fixedly connected to the arc-shaped template 9. A first positioning screw 2 for limiting the relative position of the horizontal tube 3 and the U-shaped frame 4 is threadedly connected to the upper surface of the U-shaped frame 4. Two second positioning screws 13 for limiting the relative position of the rectangular sleeve 12 and the vertical tube 11 are threadedly connected to the side of the rectangular sleeve 12 away from the rectangular tube 1. The position of the horizontal tube 3 is adjusted along the U-shaped frame 4 as needed. At this time, the distance between the arc-shaped template 9 and the rectangular tube 1 changes. The position of the vertical tube 11 is adjusted along the rectangular sleeve 12 to change the height of the arc-shaped template 9. When the position of the arc-shaped template 9 on the back of the curved curbstone meets the requirements, it is then used to... The first positioning screw 2 restricts the relative position of the U-shaped frame 4 and the horizontal tube 3, and the second positioning screw 13 restricts the relative position of the vertical tube 11 and the rectangular sleeve 12, thereby restricting the position of the arc template 9. At this time, the horizontal roller 6 overlaps the upper surface of the curved edge stone, and the vertical roller 5 is attached to the outer side of the curved edge stone, which facilitates movement along the curved edge stone. Concrete is added to the space between the back of the curved edge stone and the arc template 9, so that the concrete poured on the back of the curved edge stone will not have a structure that is wider at the bottom and narrower at the top. The edge stone back concrete mold is simple and convenient to operate, improves work efficiency, and has a more comprehensive pouring range. It fills the gap that was previously unable to standardize the pouring of curved backs. Back construction reduces the input of personnel, saves concrete, eliminates the need for material turnover, has low equipment cost, reduces cost input and material waste, and has high safety, high finished product aesthetics, and high quality.

[0024] See Figures 1-3A first threaded sleeve 20 is fixedly connected to the upper surface of the U-shaped frame 4. A first positioning screw 2 is threadedly connected inside the first threaded sleeve 20. One end of the first positioning screw 2 passes through the U-shaped frame 4 and contacts the horizontal tube 3. Two second threaded sleeves 21 are installed on the side of the rectangular sleeve 12 away from the rectangular tube 1. A second positioning screw 13 is threadedly connected inside the second threaded sleeve 21. One end of the second positioning screw 13 passes through the rectangular sleeve 12 and contacts the vertical tube 11. The first threaded sleeve 20 and the second threaded sleeve 21 respectively realize the stable installation of the first positioning screw 2 and the second positioning screw 13.
