Description

Technical Field

[0001] The utility model relates to the field of highway construction, in particular to a multi-layer hinge type formwork. Background Art

[0002] During the paving process of asphalt pavement, in order to ensure the straightness of the edge line and the compaction degree of the edge rolling, formwork usually needs to be installed. The structural form of asphalt pavement generally includes an upper layer, a middle layer and a lower layer. In the prior art, a single-layer formwork is usually used for installation and reinforcement. The specific operation is that after the paving and rolling of the lower layer are completed, when paving the middle layer and the upper layer in sequence, the formwork of the middle layer and the upper layer need to be installed respectively. Especially when installing the upper layer formwork, it needs to be assembled and connected with the lower layer formwork. This traditional single-layer formwork installation method is widely used in the edge paving and rolling of asphalt pavement.

[0003] However, the single-layer formwork installation method in the prior art has some obvious defects. First of all, since the formwork of each layer needs to be installed and reinforced separately, the whole construction process is time-consuming and laborious, and the efficiency is low. Secondly, during multiple installations, the assembly and connection of formworks of different layers are prone to produce stepped phenomena, which not only affect the construction quality, but also may cause the formwork to deform after the asphalt mixture is paved and rolled. In addition, even after the paving and rolling of the asphalt pavement are completed, the edge line is still not straight, and it is difficult to ensure the quality of the final pavement. Therefore, the existing single-layer formwork installation method is difficult to meet the requirements of high-efficiency and precise construction, and an improved solution is urgently needed to overcome these deficiencies. Summary of the Utility Model

[0004] Aiming at the above defects of the prior art solutions, the main purpose of the utility model is to develop a new type of multi-layer hinge type formwork, which can effectively solve the problems of time-consuming and laborious, easy to produce stepped phenomena during multiple assemblies, formwork deformation and non-straight line shape existing in the traditional single-layer formwork during the paving process of asphalt pavement.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multi-layer hinge type formwork for asphalt pavement paving, comprising a first formwork panel, a second formwork panel and a third formwork panel. Interleaved and butt-jointed pin barrels are fixedly arranged between the first formwork panel and the second formwork panel, and between the second formwork panel and the third formwork panel. A plug rod is inserted into the pin barrel. Threaded grooves and pin caps are arranged at both ends of the plug rod. The pin caps are rotated into the interior of the threaded grooves. The first formwork panel and the second formwork panel, and the second formwork panel and the third formwork panel are both rotatably connected at 180°.

[0007] Preferably, the first template panel, the second template panel and the third template panel are all composed of a combination of double-layer steel plates and four-sided frames.

[0008] Preferably, the pin cylinders between the first template panel and the second template panel include a first group of pin cylinders and a second group of pin cylinders. The first group of pin cylinders is fixedly connected to the first template panel, and the second group of pin cylinders is fixedly connected to the second template panel.

[0009] Preferably, the pin cylinders between the second template panel and the third template panel include a third group of pin cylinders and a fourth group of pin cylinders. The third group of pin cylinders is fixedly connected to the second template panel, and the fourth group of pin cylinders is fixedly connected to the third template panel.

[0010] Preferably, the pin cylinders between the first template panel and the second template panel and the pin cylinders between the second template panel and the third template panel are located on different sides of the template.

[0011] Preferably, the pin cover includes a cylindrical end and a plug rod. The surface of the plug rod is provided with an external thread, and the thread groove is provided with an internal thread. When the pin cover rotates into the interior of the thread groove, the external thread cooperates with the internal thread.

[0012] Preferably, the four-sided frame includes front and rear frames and side frames on both sides. The side frames are provided with template connection holes for connecting with other templates.

[0013] Preferably, the template connection holes are evenly arranged.

[0014] The beneficial effects of the present utility model are as follows: First, the multi-layer hinge-type template has a simple structure, and is very convenient for manufacturing and assembling, significantly reducing the complexity of production and construction. Second, by means of hinge rotation, the template can be easily opened and folded, suitable for various template requirements of different sizes, and has strong adaptability. In practical applications, when the template is in the folded state, its volume is greatly reduced, facilitating stacking and storage, saving storage space. In addition, the setting of the hinge structure enables only one installation operation to be performed when installing multi-layer templates during the paving of asphalt pavement, greatly improving the construction efficiency, reducing the step difference phenomenon during the assembly process, and effectively avoiding the deformation problem of the template, ensuring that the edge line of the paved road surface is more straight. In summary, the present utility model not only optimizes the installation process of the template, but also significantly improves the construction quality and efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the present invention.

[0022] In addition, the described features, structures or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to give a full understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present application.

[0023] Please refer to Figures 1-4, this embodiment discloses a multi-layer hinge-type template for asphalt pavement paving, which includes a first template panel 1, a second template panel 2, and a third template panel 3, corresponding to the lower layer, middle layer, and upper layer of the asphalt pavement paving respectively. Between the first template panel 1 and the second template panel 2, and between the second template panel 2 and the third template panel 3, there are fixedly arranged pin barrels 4 that are staggeredly butted. The pin barrels 4 are fixedly arranged on adjacent template panels in a staggered manner to ensure that each template panel can maintain a stable connection when the template is unfolded and folded. An insertion rod 5 is inserted into the pin barrel 4, and the insertion rod 5 passes through all the pin barrels 4, enabling the template panels to be connected together by the insertion rod 5 to form a whole. Threaded grooves 6 and pin caps 7 are provided at both ends of the insertion rod 5. The threaded grooves 6 are located at both ends of the insertion rod 5, providing parts for threaded connection, while the pin caps 7 enter the inside of the threaded grooves 6 by rotation to ensure the fixation of the insertion rod 5 in the pin barrel 4, thereby preventing the insertion rod 5 from slipping out of the pin barrel 4 during use. The first template panel 1 and the second template panel 2, as well as the second template panel 2 and the third template panel 3, are rotatably connected at 180°. The template panels can rotate around the insertion rod 5, enabling the template to be freely unfolded and folded when paving the asphalt pavement, improving the convenience and efficiency of construction.

[0024] The first template panel 1, the second template panel 2, and the third template panel 3 are all composed of a combination of double-layer steel plates and four-sided frames, and specifically, welding can be used. Each template panel is composed of two layers of steel plates and a frame structure surrounding the four sides. This structural design not only enhances the overall strength of the template but also improves the durability and service life of the template. The pin barrels 4 between the first template panel 1 and the second template panel 2 include a first group of pin barrels and a second group of pin barrels. The first group of pin barrels is fixedly connected to the first template panel 1, and the second group of pin barrels is fixedly connected to the second template panel 2. At the connection of the template panels, the first group of pin barrels is firmly attached to the first template panel 1, and the second group of pin barrels is fixedly connected to the second template panel 2. Through this staggered docking design of the pin barrels, a stable connection between the template panels is ensured, avoiding loosening or dislocation that may occur during use. Similarly, the pin barrels 4 between the second template panel 2 and the third template panel 3 include a third group of pin barrels and a fourth group of pin barrels. The third group of pin barrels is fixedly connected to the second template panel 2, and the fourth group of pin barrels is fixedly connected to the third template panel 3. The template panels are connected together by multiple groups of pin barrels, and each group of pin barrels is fixedly connected to the corresponding template panel. This multi-point fixation method enhances the stability of the entire template structure, enabling the template to freely rotate and adjust its position while maintaining stability during actual operation.

[0025] The pin cylinders 4 between the first template panel 1 and the second template panel 2 and the pin cylinders 4 between the second template panel 2 and the third template panel 3 are located on different sides of the template, which can ensure that when the template rotates or folds, the template panels will not interfere with each other, thus achieving smoother operation. Specifically, the pin cylinder 4 between the first template panel 1 and the second template panel 2 can be located on the front side, and the pin cylinder 4 between the second template panel 2 and the third template panel 3 can be located on the rear side, ensuring smoother unfolding and folding of the template during actual construction.

[0026] Furthermore, the pin cover 7 includes a cylindrical end and a plug rod. The surface of the plug rod is provided with external threads, and the threaded groove 6 is provided with internal threads. When the pin cover 7 rotates into the inside of the threaded groove 6, the external threads cooperate with the internal threads, and the cylindrical end abuts against the template panel, achieving a firm connection. This way of thread cooperation ensures that the plug rod 5 can be stably fixed in the pin cylinder 4 and prevents it from falling off during use. The four-sided frame 8 includes front and rear frames and side frames 8 on both sides. Template connection holes 9 for connecting with other templates are opened on the side frames 8. These template connection holes 9 are evenly arranged on the side frames 8, ensuring the stability and consistency when the template is connected to other templates and avoiding problems such as loose connection or uneven connection points.

[0027] In summary, the present utility model discloses a multi-layer hinge-type template applicable to asphalt pavement paving. The template includes multiple template panels, which are connected by staggered pin cylinders 4 and plug rods 5. Each template panel can rotate 180°, so as to be flexibly unfolded or folded. The template panel adopts a structural design of double-layer steel plates and a four-sided frame 8, enhancing the overall strength and durability. The thread cooperation between the pin cover 7 and the threaded groove 6 ensures the stable fixation of the plug rod 5 and prevents it from falling off. In addition, the template connection holes 9 on the side frames 8 are evenly arranged, facilitating the connection with other templates, improving the construction efficiency and connection stability. Through the structural design of the present utility model, not only the installation and disassembly process of the template is simplified, but also problems such as stepped joints and deformation that occur in traditional templates during construction are effectively avoided, greatly improving the construction quality and efficiency.
