Description

Technical Field

[0001] This utility model relates to the field of road paving tools, and in particular to a fixing structure for a phosphogypsum roadbed paving template. Background Technology

[0002] In road construction, the quality of the subgrade paving directly affects the overall performance and service life of the road. Phosphogypsum, a common industrial byproduct, is gaining increasing attention for its application in subgrade materials due to its favorable physicochemical properties. However, in the construction of phosphogypsum subgrades, formwork fixing is a crucial step, affecting not only the shape and dimensional accuracy of the subgrade but also the quality of subsequent concrete pouring.

[0003] Traditional formwork fixing methods typically use simple wooden stakes or steel bars for support. This approach suffers from poor stability and inconvenient adjustments, especially in complex terrain conditions. It struggles to ensure the verticality and flatness of the formwork, easily leading to deviations after the roadbed is formed, thus affecting project quality. Furthermore, traditional fixing methods are difficult to dismantle, increasing construction costs and time. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a phosphogypsum roadbed paving template fixing structure. To achieve the above objective, this utility model adopts the following technical solution:

[0005] A template fixing structure for phosphogypsum roadbed paving includes a drill rod, a sleeve, a support plate, and several bolts. The drill rod is fixed on the roadbed, and the upper section of the drill rod is threaded. The sleeve is threaded onto the drill rod. A connecting lug is fixedly connected to one side of the support plate, and the connecting lug is fixedly connected to the sleeve. A connecting hole is opened on the support plate, and the bolts are set in the connecting hole and located on both sides of the drill rod. The bolts are used to fix the template to the support plate.

[0006] Furthermore, three bolts are provided, one bolt located on one side of the drill rod and the other two located on the other side of the drill rod.

[0007] Furthermore, the support plate is made of stainless steel, and its cross-section is set in an arc shape, with more than one contact point with the template.

[0008] Furthermore, a spring is fitted onto the bolt, and the spring is located between the support plate and the template.

[0009] Furthermore, the bolt is fitted with several washers, which are located on both sides of the support plate, along with the spring.

[0010] Furthermore, the drill rod is also threaded with two nuts, which are located at both ends of the sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The combination of chisels and sleeves provides stronger fixing force, making the formwork stable throughout the construction process and less prone to displacement, thereby improving the accuracy of roadbed forming;

[0013] 2. The fixed structure is simple in design and easy to operate, and can quickly complete the installation and dismantling of the template, which greatly shortens the construction cycle and reduces labor intensity;

[0014] 3. It is suitable for different types of terrain and construction environment, especially for phosphogypsum subgrade paving under irregular or complex terrain conditions, showing excellent adaptability;

[0015] 4. The threaded connection design allows for fine-tuning of the formwork position during construction, ensuring that the final roadbed meets design requirements and effectively utilizes phosphogypsum, an industrial byproduct, promoting resource recycling, reducing environmental pollution, and conforming to the concept of sustainable development.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 , Figure 2A template fixing structure for phosphogypsum roadbed paving includes a drill rod 1, a sleeve 2, a support plate 3, and several bolts 4. The drill rod 1 is fixed to the roadbed, and its upper section is threaded. The sleeve 2 is threaded onto the drill rod 1. A connecting lug 5 is fixedly connected to one side of the support plate 3, and the connecting lug 5 is fixedly connected to the sleeve 2. The support plate 3 has connecting holes, and the bolts 4 are disposed in the connecting holes and located on both sides of the drill rod 1. The bolts 4 are used to fix the template 9 to the support plate 3. The drill rod 1 can be an anchor rod for easy construction.

[0022] The working principle is that the drill rod 1 is firmly fixed to the roadbed by mechanical or chemical means. Its upper section is threaded for threaded connection with the sleeve 2. The sleeve 2 serves as an intermediate connector, with one end threaded to the drill rod 1 and the other end fixedly connected to the connecting lug 5 on the support plate 3. The support plate 3 has connecting holes, through which bolts 4 pass and are distributed on both sides of the drill rod 1, firmly fixing the template 9 to the support plate 3. This design allows the template 9 to be stably installed in the predetermined position and can be flexibly adjusted as needed, ensuring accuracy and efficiency in the roadbed laying process.

[0023] In this embodiment, as Figure 1 As shown, three bolts 4 are provided, one bolt 4 is located on one side of the drill rod 1, and the other two are located on the other side of the drill rod 1. Using three bolts 4, the template 9 can be firmly fixed to the support plate 3, making the structure more robust.

[0024] In this embodiment, as Figure 2 As shown, the support plate 3 is made of stainless steel, and its cross-section is arc-shaped, with more than one contact point with the template 9. The stainless steel support plate 3 has a certain degree of elasticity, which helps to make the template 9 more firmly fixed to the support plate 3 when the template 9 is fixed to the support plate 3 using bolts 4.

[0025] In this embodiment, as Figure 2 As shown, a spring 6 is fitted onto the bolt 4, and the spring 6 is located between the support plate 3 and the template 9. The spring 6 is used to further increase the fixing firmness between the template 9 and the support plate 3.

[0026] In this embodiment, as Figure 2 As shown, several washers 7 are fitted onto the bolt 4, and the washers 7 and the spring 6 are located on opposite sides of the support plate 3. The washers 7 are used to improve the tightness of the bolt 4 and prevent it from loosening.

[0027] In this embodiment, as Figure 2As shown, the drill rod 1 is also threaded with two nuts 8, which are located at both ends of the sleeve 2. The nuts 8 on the lower part of the sleeve 2 are used to position the sleeve 2, and the nuts 8 on the upper part of the sleeve 2 are used to tighten the sleeve 2, prevent the sleeve 2 from loosening, and improve the tightening effect of the sleeve 2.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
