Description

Technical Field

[0001] The utility model relates to the technical field of the installation of steel formwork for water-stable base courses, in particular to an installation device for steel formwork of water-stable base courses. Background Technique

[0002] The steel formwork for water-stable base courses is a formwork support system specially used for the construction of the base course of highway pavement. In modern highway construction, in order to ensure the stability and durability of the pavement structure, it is crucial to use steel formwork as the support structure for the water-stable base course during the construction process. The main function of the steel formwork is to ensure that the shape and thickness of the water-stable base course during construction meet the design requirements until the material hardens to sufficient strength. In the construction of the base course of highway pavement, especially in the construction of large-thickness paving, the use of steel formwork can effectively control the thickness and quality of the base course, ensuring the long-term stability and durability of the pavement after construction. In addition, the use of steel formwork can greatly improve the construction efficiency and the level of quality control.

[0003] The traditional method for installing steel formwork is to place the steel formwork on the positioning line manually, and then use a manual hammer to drive a steel drill to fix the steel formwork. This method has the problems of requiring workers to perform repetitive and heavy work for a long time, low construction efficiency, and high construction cost. Therefore, it does not meet the existing requirements, and an installation device for steel formwork of water-stable base courses is proposed for this. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation device for steel formwork of water-stable base courses. By connecting the installation device body with a crawler excavator, the installation device body includes clamping plates and vibrators. After clamping the steel formwork body with two clamping plates, the operator drives the crawler excavator to place the steel formwork body along the positioning line. Then, use the two clamping plates to clamp the steel drill, and the operator drives the crawler excavator to insert the steel drill into the inside of the semi-circular sleeve and the support cylinder, so that the steel formwork body is fixed, reducing the workload of workers and improving the construction efficiency, and can solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An installation device for steel formwork of water-stable base courses, including a steel formwork body, and further including an installation device body. The installation device body includes a turntable, a mounting plate, a vibrator, a fixing plate, a guard plate, clamping plates, a track plate and a hydraulic cylinder. A crawler excavator is arranged on one side of the installation device body. Semi-circular sleeves are arranged at both ends of the steel formwork body, a support cylinder is arranged on one side of the steel formwork body, the steel formwork body is connected with the support cylinder through a support frame, steel drills are arranged inside both the support cylinder and the semi-circular sleeve, and a ground-touching tip is arranged at the lower end of the steel drill.

[0006] Preferably, the turntable is located above the mounting plate. The mounting device body is connected to the crawler excavator through the turntable. The vibrator is located inside the mounting plate, and the track plate is located below the mounting plate.

[0007] Preferably, at least two fixing plates are provided. The two fixing plates are respectively located at both ends of the track plate. The track plate is connected to the vibrator through the fixing plates. The guard plate is located on the side of the track plate and is connected to the fixing plate.

[0008] Preferably, at least two clamping plates are provided. The two clamping plates are both installed on the track plate. A limiting plate is provided on the upper surface of the clamping plate, and sawteeth are provided on the lower surface of the clamping plate.

[0009] Preferably, at least three support cylinders are provided. The steel drill rod is configured as a plain round steel bar, and the diameter of the semi-circular sleeve is equal to that of the steel drill rod.

[0010] Preferably, the hydraulic cylinder is located between the vibrator and the track plate. One end of the hydraulic cylinder is connected to the fixing plate, and the other end of the hydraulic cylinder is provided with a telescopic rod. One end of the telescopic rod is located inside the hydraulic cylinder, and the other end of the telescopic rod is connected to the limiting plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By connecting the mounting device body to the crawler excavator, the mounting device body includes clamping plates and a vibrator. After the two clamping plates clamp the steel formwork body, the operator drives the crawler excavator to place the steel formwork body along the positioning line. Then, the two clamping plates are used to clamp the steel drill rod, and the operator drives the crawler excavator to insert the steel drill rod into the inside of the semi-circular sleeve and the support cylinder. The vibrator generates a vertical up-and-down vibration force to drive the bottom end of the steel drill rod into the inside of the subbase, so that the steel formwork body is fixed, reducing the workload of workers and improving the construction efficiency.

[0013] 2. By providing at least three support cylinders on the side of the steel formwork body, each support cylinder is connected to the steel formwork body through a support frame. After the steel formwork body is fixed, one side of the steel formwork body is subjected to the extrusion force of the water-stable base course, and the other side of the steel formwork body is subjected to the supporting force given by the steel drill rod in the support cylinder, thus achieving a two-force balance, making it difficult for external forces to overturn the steel formwork body and improving the construction quality. At the same time, after the construction of the water-stable base course is completed, the steel drill rod is pulled out through the mounting device body, so that the steel drill rod can be reused, reducing the construction cost.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] To solve the problems that when fixing the steel formwork, workers need to perform repetitive and heavy work for a long time, the construction efficiency is low, and the construction cost is high, please refer to Figures 1-5 An embodiment provided by the present utility model: An installation device for a water-stable base steel formwork includes a steel formwork body 3, and also includes an installation device body 1. The installation device body 1 includes a turntable 101, an installation plate 102, a vibrator 103, a fixed plate 104, a protective plate 105, a clamping plate 106, a track plate 107 and a hydraulic cylinder 108. A crawler excavator 2 is arranged on one side of the installation device body 1. Semi-circular sleeves 301 are arranged at both ends of the steel formwork body 3. A support cylinder 302 is arranged on one side of the steel formwork body 3. The steel formwork body 3 is connected to the support cylinder 302 through a support frame 303. Steel drill rods 4 are arranged inside both the support cylinder 302 and the semi-circular sleeve 301. A ground contact tip 401 is arranged at the lower end of the steel drill rod 4. At least three support cylinders 302 are provided. The structure of the steel drill rod 4 is a smooth round steel bar with a diameter of 30 mm and a length of 50 cm. The diameter of the semi-circular sleeve 301 is 30 mm.

[0022] The turntable 101 is located above the mounting plate 102. The mounting device body 1 is connected to the crawler excavator 2 through the turntable 101. The vibrator 103 is located inside the mounting plate 102. The track plate 107 is located below the mounting plate 102. There are at least two fixing plates 104, and the two fixing plates 104 are respectively located at both ends of the track plate 107. The track plate 107 is connected to the vibrator 103 through the fixing plate 104. The guard plate 105 is located on the side of the track plate 107, and the guard plate 105 is connected to the fixing plate 104.

[0023] There are at least two clamping plates 106, and the two clamping plates 106 are both installed on the track plate 107. A limiting plate 1061 is arranged on the upper surface of the clamping plate 106, and a sawtooth 1062 is arranged on the lower surface of the clamping plate 106. The hydraulic cylinder 108 is located between the vibrator 103 and the track plate 107. One end of the hydraulic cylinder 108 is connected to the fixing plate 104, and the other end of the hydraulic cylinder 108 is provided with a telescopic rod 1081. One end of the telescopic rod 1081 is located inside the hydraulic cylinder 108, and the other end of the telescopic rod 1081 is connected to the limiting plate 1061.

[0024] The personnel clean the subbase and keep the subbase flat. At the same time, measure and set out the positioning line on the subbase and mark it. After the hydraulic cylinder 108 controls the telescopic rod 1081 to drive the two clamping plates 106 to clamp the steel drill rod 4, the personnel first drive the crawler excavator 2 to place the steel drill rod 4 along the positioning line. The interval between the steel drill rods 4 is the length of a single steel formwork body 3. The steel drill rod 4 is driven into the subbase by 20 cm - 30 cm by the up-and-down vibration force generated by the vibrator 103. Then the personnel clamp the steel formwork body 3 and place it on the positioning line through the crawler excavator 2, so that the steel drill rod 4 on the positioning line is located in the semi-circular sleeves 301 at both ends of the steel formwork body 3. Finally, the support frame 303 and the support cylinder 302 are installed on the side of the steel formwork body 3, and at the same time, the steel drill rod 4 is driven into the inside of each support cylinder 302. The steel drill rod 4 inside the support cylinder 302 needs to be driven into the subbase by at least 30 cm, thereby completing the fixation of the steel formwork body 3, reducing the workload of the workers and further improving the construction efficiency. At the same time, when the construction of the water-stable base layer is completed and the water-stable base layer reaches the design strength, after the mounting device body 1 clamps the steel drill rod 4, the crawler excavator 2 drives the mounting device body 1 to pull out the steel drill rod 4, and then removes the steel formwork body 3. The pulled-out steel drill rod 4 can be reused, further reducing the construction cost.

[0025] After the steel formwork body 3 is fixed, one side of the steel formwork body 3 is subjected to the extrusion force of the water-stable base layer, and the other side of the steel formwork body 3 is subjected to the supporting force given by the steel drill rod 4 in the support cylinder 302, so as to achieve two-force balance, making it difficult for external forces to overturn the steel formwork body 3 and further improving the construction quality.

[0026] Working principle: After the installation device body 1 clamps the steel drill rod 4, the operator first drives the crawler excavator 2 to place the steel drill rod 4 along the positioning line, then clamps the steel formwork body 3 and places it on the positioning line through the crawler excavator 2, so that the steel drill rod 4 on the positioning line is located in the semi-circular sleeves 301 at both ends of the steel formwork body 3. Finally, the steel drill rod 4 is driven into the interior of each support cylinder 302, thereby completing the fixation of the steel formwork body 3, reducing the workload of workers and improving the construction efficiency.
