Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a quick-release support device for water-stabilized paving templates. Background Technology

[0002] Water-stabilized paving is a key construction technique in road engineering. It refers to the uniform and continuous laying of cement-stabilized crushed stone mixture on the subgrade or base course using specific mechanical equipment. After compaction, it forms a stable and dense pavement structure layer, providing a load-bearing foundation for the road.

[0003] In existing technologies, during the paving of water-stabilized road surface or while waiting for the road to harden, multiple support templates need to be installed on both sides of the road. At this time, workers will align the sides of the multiple support templates together. Usually, one support template is placed vertically on the ground first, and then the side of another support template is aligned with the side of the already placed template, so that the two templates fit tightly together. This ensures that the multiple templates are on the same vertical plane, thereby ensuring the quality of the paved road.

[0004] However, in the aforementioned process, when assembling the formwork, workers need to slowly align one support formwork piece with another, and this alignment process is done visually. This not only introduces potential errors but is also very slow, affecting both the quality of the paved road and the efficiency of road construction. Therefore, we propose a quick-release support device for water-stabilized paving formwork to effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release support device for water-stabilized paving templates, in order to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a quick-release support device for water-stabilized paving template, comprising a channel steel template, the channel steel template being U-shaped, two connecting plates fixedly provided on the inner side of the channel steel template, the two connecting plates being symmetrically distributed from left to right, and the opposite sides of the two connecting plates being flush with the left and right sides of the channel steel template respectively, a combination sleeve being movably provided on the connecting plate, the combination sleeve being used to connect the connecting plates on different channel steel templates to combine different channel steel templates together, the combination sleeve being provided with a support component, the support component being used to support the channel steel template.

[0007] Optionally, the top projection shape of the combined sleeve is U-shaped, and the combined sleeve is slidably fitted on the outside of the connecting plate along the vertical direction.

[0008] Optionally, the two connecting plates on the same channel steel template have sliding grooves on their facing surfaces, and two sliders are fixedly provided on the inner side of the combined sleeve. The two sliders are symmetrically distributed from left to right, and the sliders are slidably connected in the sliding grooves.

[0009] Optionally, there is a gap between the top surface of the connecting plate and the inner top surface of the channel steel template, and the height of the combined sleeve is not greater than the gap between the top surface of the connecting plate and the inner top surface of the channel steel template.

[0010] Optionally, the support assembly includes a hinge seat fixedly connected to the side of the combined sleeve away from the channel steel template, a support rod hinged to the hinge seat, and the movable end of the support rod hinged to a horizontal plate.

[0011] Optionally, the top surface of the horizontal plate has a through hole, into which a ground nail can be inserted to fix the support component.

[0012] Compared with the prior art, this utility model provides a quick-release support device for water-stabilized paving formwork, which has the following beneficial effects:

[0013] 1. This utility model sets two connecting plates inside the template, and the sides of the connecting plates on the two templates can fit together. Then, a combination sleeve is used to fit the connecting plates on the two templates inside, so that the two connecting plates are connected together, thereby making the sides of the two templates fit together to complete the combination. The combination process is convenient and fast, and can also avoid the two templates from shifting, which would cause the water-stabilized material to seep out from the side.

[0014] 2. This utility model fixes the combination sleeve and the support component together, so that workers can install the support component at the same time when assembling two templates, and can separate the two templates at the same time when disassembling the support component, thereby improving the assembly and disassembly speed and construction efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 A quick-release support device for water-stabilized paving templates includes a channel steel template 1, which is U-shaped. Two connecting plates 2 are fixedly installed on the inner side of the channel steel template 1. The two connecting plates 2 are arranged vertically and are symmetrically distributed from left to right. The back sides of the two connecting plates 2 are flush with the left and right sides of the channel steel template 1, respectively, so that when the sides of the connecting plates 2 on different channel steel templates 1 are put together, the mating surfaces of the two channel steel templates 1 can also be put together synchronously.

[0023] Furthermore, a combination sleeve 3 is movably provided on the connecting plate 2. The combination sleeve 3 is used to connect the connecting plates 2 on different channel steel templates 1 so that the different channel steel templates 1 can be combined together. Specifically, in this embodiment, the top projection shape of the combination sleeve 3 is U-shaped. The combination sleeve 3 is slidably fitted on the outside of the connecting plate 2 along the vertical direction, and the inner width of the combination sleeve 3 is equal to the sum of the widths of the two connecting plates 2. Therefore, the combination sleeve 3 can fit the two mutually fitting connecting plates 2 inside, thereby achieving a tight fit between the two connecting plates 2 and achieving the purpose of combining the two connecting plates 2. This allows the two channel steel templates 1 to also be combined together, reducing the gap between the two channel steel templates 1 and preventing leakage of the water-stabilized material.

[0024] There is a gap between the top surface of the connecting plate 2 and the inner top surface of the channel steel template 1. The height of the combined sleeve 3 is not greater than the gap between the top surface of the connecting plate 2 and the inner top surface of the channel steel template 1. Therefore, the combined sleeve 3 can enter the gap between the top surface of the connecting plate 2 and the inner top surface of the channel steel template 1, making it easy to put the combined sleeve 3 on the outside of the connecting plate 2 or to remove it from the outside of the connecting plate 2. This allows workers to remove the combined sleeve 3 after the road has solidified, preventing the two connecting plates 2 from being restricted by the combined sleeve 3, thus separating the two channel steel templates 1 and facilitating workers to disassemble several channel steel templates 1 one by one from the side of the road.

[0025] In this embodiment, two connecting plates 2 on the same channel steel template 1 have sliding grooves 201 on their facing surfaces. Two sliders 301 are fixedly mounted on the inner side of the combined sleeve 3. The two sliders 301 are symmetrically distributed left and right, and are slidably connected within the sliding grooves 201. Figure 4 and Figure 5 As shown, when the slider 301 slides within the groove 201, it is precisely embedded within the groove 201. At this time, the combined sleeve 3 cannot move along the width direction of the channel steel template 1. Simultaneously, the frictional resistance between the slider 301 and the groove 201 is relatively large. Specifically, in this embodiment, the slider 301 can only slide within the groove 201 when the operator applies a horizontal force greater than 5N to the combined sleeve 3, ensuring that the combined sleeve 3 will not slide without external force, thereby improving the stability of the combined sleeve 3.

[0026] Furthermore, the combination sleeve 3 is provided with a support component 4, which is used to support the channel steel template 1 so that the channel steel template 1 can be supported and thus more stable when it is used.

[0027] Specifically, the support assembly 4 includes a hinge seat 401 fixedly connected to the side of the combined sleeve 3 away from the channel steel template 1. A support rod 402 is hinged to the hinge seat 401, and the movable end of the support rod 402 is hinged to the horizontal plate 403. The support rod 402 is rotatably connected to the support rod 402 via a hinge shaft. The hinge shaft and the support rod 402 are fixedly connected, and the hinge shaft and the hinge seat 401 are rotatably connected via a damping bearing, so that the support rod 402 will not wobble when no external force is applied.

[0028] Furthermore, a through hole 404 is provided on the top surface of the horizontal plate 403, such as... Figure 2 As shown, the inner bottom wall of the channel steel formwork 1 is provided with ground nail holes 101. Ground nails can be inserted into both the ground nail holes 101 and the through holes 404, so that the channel steel formwork 1 and the support assembly 4 can be fixed to the ground. The ground nails at the ground nail holes 101 fix the channel steel formwork 1 near the bottom, while the end of the support assembly 4 near the combined sleeve 3 fixes the channel steel formwork 1 near the top, so that the channel steel formwork 1 can be stably fixed to the ground, improving the quality of the construction road.

[0029] It is worth mentioning that, since the combined sleeve 3 can slide vertically on the connecting plate 2, and both ends of the support rod 402 are hinged, the tilt angle of the support component 4 can be adjusted, thereby adjusting the support force of the support component 4 on the channel steel formwork 1. Specifically, the closer the combined sleeve 3 is to the bottom of the channel steel formwork 1, the greater the horizontal support force of the support component 4 on the channel steel formwork 1; the closer the combined sleeve 3 is to the top of the channel steel formwork 1, the smaller the horizontal support force of the support component 4 on the channel steel formwork 1. This allows workers to change the support force on the channel steel formwork 1 according to the road construction needs, making it suitable for the construction of pavements made of different water-stabilized materials.

[0030] Application scenarios and operation procedures of this utility model: In road base construction (such as water-stabilized layer paving), road materials need to be laid in the construction area. At this time, by setting up templates with supporting structures on both sides of the road, not only can the road sides be limited when materials such as asphalt or concrete solidify, thereby preventing the loss of construction materials; it can also prevent the templates from deforming, shifting or collapsing when the road roller is compacted, thereby ensuring the flatness, compaction and edge forming effect of the water-stabilized layer.

[0031] In use, firstly, place the first channel steel template 1 vertically at the edge of the road in the construction area, with the open side of the first channel steel template 1 facing away from the road. Then, place the other channel steel template 1 to the side of the first channel steel template 1, so that the sides of the two channel steel templates 1 are joined together, and the adjacent connecting plates 2 on the two channel steel templates 1 are attached together. Subsequently, insert the combined sleeve 3 with the support component 4 into the gap between the connecting plate 2 and the inner top surface of the channel steel template 1, and slide the combined sleeve 3 downward onto the two connecting plates 2. At this time, the slider 301 is embedded in the sliding groove 201, which limits the two connecting plates 2, so that the combined sleeve 3 can lock the adjacent connecting plates 2 on the two channel steel templates 1 together, thereby combining the two channel steel templates 1. Finally, adjust the tilt angle of the support rod 402 and the height of the combined sleeve 3 according to construction requirements, so that the horizontal plate 403 is placed horizontally on the ground. Use ground nails inserted into the ground nail holes 101 and through holes 404 to fix the channel steel formwork 1 and the support assembly 4, thus ensuring the channel steel formwork 1 is stably fixed to the ground and preventing lateral displacement and collapse of the road edge. Other channel steel formwork 1s are installed in the same manner. During disassembly, simply remove the ground nails and slide the combined sleeve 3 on the connecting plate 2 upwards to remove the combined sleeve 3, thereby disassembling the support assembly 4 and facilitating the demolding operation of the channel steel formwork 1.
