Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, and in particular to a concrete side formwork for rural roads in mountainous areas. Background Technology

[0002] Highway concrete side formwork is a template structure used in highway concrete construction to define the boundaries of concrete pouring and support the concrete forming process. It is mostly made of steel or composite materials and has sufficient strength and rigidity to withstand the lateral pressure during concrete pouring. Its structural design must meet the requirements of highway alignment. It can be spliced ​​and fixed by bolts, clips, etc. to ensure tight joints and prevent grout leakage. During construction, it is installed on both sides of the roadbed and can accurately control the size and shape of concrete curbs, side ditches, and other components. It is removed after the concrete hardens. It is an important construction tool to ensure the appearance quality and linear accuracy of highway projects.

[0003] Existing technologies often have the following drawbacks: In order to meet driving safety, highways need to be widened at bends. However, mountainous rural roads are characterized by sharp bends and steep slopes, especially at hairpin bends with a longitudinal slope of more than 15%. It is difficult to set up concrete road formwork. After the road is formed, it not only affects driving safety but also hinders the image of beautiful rural roads.

[0004] Therefore, this utility model provides a concrete side formwork for rural roads in mountainous areas. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing 3-meter standard steel molds, which can lead to uneven road alignment, and to propose a concrete side mold for rural roads in mountainous areas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete side mold for rural roads in mountainous areas, comprising several steel side molds, two of which are connected by steel hinges, a side mold support is rotatably installed on the inner side of each steel side mold, and a tapered rod is slidably connected inside the side mold support.

[0007] The effect achieved by the above components is as follows: the existing three-meter-long steel side mold is divided into three one-meter-long steel side molds, which are connected end to end by steel hinges. The contact points between the steel hinges and the steel side molds are welded together, and the original three-meter angle change is adjusted to a one-meter angle change, increasing the flexibility of road alignment adjustment.

[0008] Preferably, an upper baffle is fixedly connected to the upper end of the cone rod, and a lower baffle is fixedly connected to the lower side of the cone rod.

[0009] The effect achieved by the above components is that by setting the upper baffle and the lower baffle, the phenomenon of the cone rod sliding out from the side mold support is avoided.

[0010] Preferably, the cone rod has a hollow structure, and two horizontal insert plates are slidably connected to the lower side of the cone rod.

[0011] The effect achieved by the above components is that the horizontal insertion plate can be inserted horizontally into the muddy ground, further improving the stability of the cone rod when inserted into the ground.

[0012] Preferably, the end side of the transverse insert plate has a pointed structure.

[0013] The effect achieved by the above components is that the setting of the tip structure horizontal insertion plate improves the efficiency of the horizontal insertion plate being inserted into the ground.

[0014] Preferably, a push plate is fixedly connected to the side of each of the two horizontal insert plates that are close to each other, a fixing block is fixedly connected to the inner side of the cone rod, a limit plate is fixedly connected to the upper end of the fixing block, and the push plate and the horizontal insert plate are slidably connected to the side wall of the limit plate.

[0015] The effect achieved by the above components is that the sliding of the push plate and the horizontal insertion plate on the surface of the limiting plate restricts the direction of movement of the horizontal insertion plate.

[0016] Preferably, the upper baffle is internally threaded with a screw, and the lower end of the screw is fixedly connected with a cone.

[0017] The effect achieved by the above components is that rotating the screw will drive the cone head to move downwards, and during the downward movement of the cone head, the two push plates can be pushed away from each other to one side.

[0018] Preferably, a spring is fixedly connected between the push plate and the fixing block.

[0019] The effect achieved by the above components is that when the screw is rotated in the opposite direction, the push plate will be pulled back to its original position by the spring force, which facilitates the subsequent extraction of the cone rod from the muddy ground.

[0020] In summary:

[0021] This utility model uses a special template to speed up the template erection efficiency at hairpin bends on steep longitudinal slopes, optimize the road alignment at hairpin bends on steep longitudinal slopes, ensure driving safety while beautifying the road, reduce repeated manual template adjustments, reduce formwork bursts and save concrete, and is suitable for various mountain roads to meet diverse construction needs.

[0027] Reference Figure 1-4 As shown, this utility model provides a technical solution: a concrete side formwork for rural roads in mountainous areas, comprising several steel side formworks 1, with two steel side formworks 1 connected by steel hinges 3. A side formwork support 2 is rotatably mounted on the inner side of each steel side formwork 1, and a tapered rod 4 is slidably connected inside the side formwork support 2. The existing three-meter-long steel side formwork 1 is divided into three one-meter-long steel side formworks 1, connected end-to-end by steel hinges 3. The contact points between the steel hinges 3 and the steel side formwork 1 are welded together, adjusting the original three-meter angle variation to a one-meter angle variation, increasing the flexibility of road alignment adjustment.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] In this implementation scheme: an upper baffle 5 is fixedly connected to the upper end of the cone rod 4, and a lower baffle 6 is fixedly connected to the lower side of the cone rod 4. By setting the upper baffle 5 and the lower baffle 6, the phenomenon of the cone rod 4 sliding out from the side mold support 2 is prevented.

[0030] The cone rod 4 has a hollow structure, and two horizontal insertion plates 9 are slidably connected to its lower side. These horizontal insertion plates 9 can be inserted horizontally into the soil, further improving the stability of the cone rod 4 when inserted into the ground. The ends of the horizontal insertion plates 9 have pointed structures. The pointed structure of the horizontal insertion plates 9 improves the efficiency of their insertion into the soil. Push plates 10 are fixedly connected to the sides of the two horizontal insertion plates 9 that are close to each other. A fixing block 11 is fixedly connected to the inner side of the cone rod 4, and a limiting plate 13 is fixedly connected to the upper end of the fixing block 11. Both the push plates 10 and the horizontal insertion plates 9 are slidably connected to the side wall of the limiting plate 13. The sliding of the push plates 10 and the horizontal insertion plates 9 on the surface of the limiting plate 13 restricts the direction of movement of the horizontal insertion plates 9.

[0031] Specifically, the upper baffle 5 has an internal threaded connection to a screw 7, and a cone 8 is fixedly connected to the lower end of the screw 7. Rotating the screw 7 drives the cone 8 to move downwards, which pushes the two push plates 10 apart to one side. A spring 12 is fixedly connected between the push plate 10 and the fixing block 11. Rotating the screw 7 in the opposite direction causes the push plate 10 to be pulled back to its original position by the tension of the spring 12, facilitating the subsequent removal of the cone 4 from the muddy ground.

[0032] The working principle involves dividing the existing three-meter-long steel side formwork 1 into three one-meter-long steel side formwork 1s, which are then connected end-to-end by steel hinges 3. The contact points between the steel hinges 3 and the steel side formwork 1s are welded together. This adjusts the original three-meter angle variation to a one-meter angle variation, increasing the flexibility of road alignment adjustments and making the road alignment smoother. The side formwork support 2 is specifically designed for the erection of side formwork supports at hairpin bends on steep longitudinal slopes. After the road alignment is laid out on the construction site, the aforementioned special template is used to erect the side formwork supports at the hairpin bends on steep longitudinal slopes according to the laid-out alignment. After unfolding the steel formwork support, the cone rod 4 is inserted into the ground, further improving the stability of the steel side formwork 1. The upper baffle 5 and lower baffle 6 prevent the cone rod 4 from slipping out of the side formwork support 2. After the cone rod 4 is inserted into the ground, the lower baffle 6 provides support above the ground. Rotating screw 7 drives cone head 8 downwards. During the downward movement of cone head 8, the two push plates 10 are pushed away from each other. The sliding of push plate 10 and horizontal insertion plate 9 on the surface of limiting plate 13 restricts the movement direction of horizontal insertion plate 9. At this time, horizontal insertion plate 9 can be inserted horizontally into the soil surface, further improving the stability of cone rod 4 when inserted into the ground. The setting of the tip structure horizontal insertion plate 9 improves the efficiency of horizontal insertion plate 9 into the soil. Rotating screw 7 in the opposite direction, push plate 10 is pulled back to its original position by the tension of spring 12, which facilitates the subsequent extraction of cone rod 4 from the soil surface. By setting the above structure, the erection time of steel side formwork 1 is greatly shortened, the formwork is stable, the line is smooth, manual line adjustment is reduced, and concrete waste is reduced.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
