Description

Technical Field

[0001] The utility model relates to the technical field of embedded pipelines, and more specifically to a telescopic embedded steel casing structure. Background Art

[0002] When modern house construction is carried out, it is usually necessary to reserve pipe openings of different diameters in the wall. Such pipe openings are used for various lines and pipelines. When pouring concrete, the embedded steel casing is usually installed directly on the formwork, fixed by the formwork, and fixed inside by welding. In order to reduce the damage to the formwork, only one side is opened, and concrete is poured after the inside is fixed. The formwork is removed after pouring to form the effect of reserved pipelines. Conventional steel casing is made by directly cutting steel pipes, which causes greater pollution on site and poses certain safety hazards. In addition, the size of the casing is greatly affected by the workers' construction level and work responsibility, and the casing size is often too long or too short. If the casing is too long, it will make it difficult to close the formwork, affecting the tightness of the formwork closing, thus affecting the quality of concrete molding; if the casing is too short, the distance between the casing inlet and outlet and the formwork will be too large, making it difficult to find and clean the casing after concrete pouring. In addition, the conventional steel casing installation process is to firmly fix the casing on the steel bar. During the concrete pouring process, the vibrating rod will disturb the steel bar, and the steel bar will shift to a certain extent. Then the position of the steel casing will also be offset, resulting in inaccurate casing positioning, which will bring inconvenience to the subsequent pipeline installation and even lead to the abandonment of the casing.

[0003] After searching, the patent with application number CN202222674029.0 discloses a telescopic embedded steel casing, including a main embedded pipe and an adjustment pipe. The outer side of the back of the main embedded pipe is equipped with an adjustment pipe; the inner side of the front of the main embedded pipe is embedded with a controller; the back of the controller is equipped with an adjustment limit frame, and the back side of the inner side of the adjustment limit frame is equipped with a bolt tightener. The utility model is equipped with an adjustment pipe, which can be tightly connected with the main embedded pipe, and can slide flexibly after the connection, and has a certain telescopic margin to adapt to different sizes of concrete components. The steel casing in the utility model is prefabricated in the factory to avoid safety hazards and environmental pollution caused by on-site processing.

[0004] This structure achieves the embedding of different casting components through movable sleeves, and makes the template fit with the embedded pipe by driving the bolt tightener through a motor. However, the positioning of the embedded pipe in this structure requires manual adjustment and calibration, which is inefficient and prone to deviations. At the same time, the bolt tightener is tightened by thread action, and the drilled hole cannot be reused when casting is performed again, resulting in a decrease in the utilization rate of the template and an increase in production costs.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4In the utility model, the telescopic embedded steel casing structure includes an embedded main pipe 1 and a movable casing 2 slidably installed on the right side thereof, the outer side of the embedded main pipe 1 is fixedly connected with a mounting plate 3, a servo motor 4 is fixedly installed on the inner wall of the embedded main pipe 1, a screw rod is fixedly connected to the output shaft of the servo motor 4, the right end of the screw rod penetrates and extends to the inside of the movable casing 2, a mounting plate 5 is fixedly connected to the inner wall of the movable casing 2, the mounting plate 5 is threadedly connected to the screw rod, a driving motor 6 is fixedly installed on the right side of the mounting plate 5, a mounting seat 7 is fixedly installed on the output shaft of the driving motor 6, and the mounting seat 7 A rotating shaft 8 is fixedly connected to the right side, and a uniformly distributed limit plate 9 is slidably installed on the inner wall of the mounting seat 7. The mounting seat 7 is provided with uniformly distributed through grooves 10, and the limit plate 9 passes through the through grooves 10 and extends to the outside of the mounting seat 7. An electromagnet 11 is installed on the inner wall of the mounting seat 7, and a magnetic plate 12 magnetically connected to the electromagnet 11 is installed on the limit plate 9. A processor 13 is installed inside the embedded main pipe 1, and an infrared ranging sensor 14 is fixedly installed on the left side of the mounting plate 5. The infrared ranging sensor 14, the servo motor 4, the drive motor 6 and the electromagnet 11 are all connected to the processor 13 signal.

[0023] A controller 15 is installed on the inner wall of the embedded main pipe 1, and the controller 15 is connected to the processor 13 by signal;

[0024] A drill bit 19 is fixedly mounted on the right end of the rotating shaft 8 , and the drill bit 19 is located on the right side of the limiting plate 9 .

[0025] The user connects the embedded main pipe 1 to the template and makes it penetrate until the mounting plate 3 fits with the left side of the template. Then the embedded main pipe 1 can be locked through the threaded hole on the mounting plate 3. Then the user inputs the width of the component to be cast through the controller 15, and the processor 13 receives the signal. The processor 13 controls the servo motor 4 to be powered on. After the servo motor 4 is powered on, it drives the screw rod fixedly connected to it to rotate synchronously. The mounting plate 5 threadedly connected to the screw rod begins to move to the right, and the movable sleeve 2 moves to the right accordingly. The drill bit 19 gradually approaches the right template. The processor 13 controls the drive motor 6 to be powered on. After the drive motor 6 is powered on, it drives the rotating shaft 8 fixedly connected to it to rotate synchronously. The drill bit 19 rotates accordingly and keeps the trend of moving to the right. As the servo motor 4 continues to operate, the drill bit 19 The template is contacted and a hole is drilled in the template, and the infrared ranging sensor 14 monitors the moving distance of the movable sleeve 2 in real time. When the movable sleeve 2 contacts the template and the value sent back by the infrared ranging sensor 14 is the same as the value of the controller 15, the processor 13 controls the servo motor 4 to stop operating. At this time, the right side of the movable sleeve 2 contacts the template, and the drill bit 19 and the rotating shaft 8 are located inside the template. The processor 13 changes the current direction of the electromagnet 11 so that the electromagnet 11 generates the same magnetic field as the magnetic plate 12. The magnetic plate 12 moves away from the electromagnet 11 to drive the limit plate 9 to move. The limit plate 9 fits the inside of the drill hole in the template to complete the limit, and then pouring can be carried out. When pouring again after the template is removed later, there is no need to open a hole so that the drill bit 19 and the rotating shaft 8 can enter the previous drill hole to complete the limit.

[0026] In the utility model, the position of the movable sleeve 2 on the embedded main pipe 1 can be changed by the servo motor 4 to meet the requirements of embedding pipes of different components, and can be automatically calibrated and adjusted in conjunction with the infrared ranging sensor 14 and the controller 15, thereby reducing the number of operating steps for personnel and improving the adjustment accuracy, and the drill bit 19 and the limit plate 9 can be used to limit the template, maintain the stability between the template and the embedded pipe, and improve the quality of casting, and the coordinated use of the electromagnet 11 and the magnetic plate 12 can change the position of the limit plate 9, so that the limit can be achieved in the drill hole in the template without the need for multiple drillings, reducing the probability of damage to the template and increasing its service life.

[0027] See also Figure 4 , wherein: a warning light 16 is installed on the inner wall of the embedded main pipe 1, and the warning light 16 is connected to the processor 13 by signal.

[0028] In the present invention, after the template limiting and steel casing pre-embedding are completed, the processor 13 will control the prompt light 16 to flash, and the prompt light 16 can serve as a prompt for nearby personnel so that subsequent steps can be carried out in time to improve efficiency.

[0029] See also Figure 1 and 3, wherein: a guide shaft 17 is fixedly connected to the inner wall of the embedded main pipe 1 , and the mounting plate 5 is slidably connected to the guide shaft 17 .

[0030] In the present invention, the setting of the guide shaft 17 can limit the movable sleeve 2, so that the movable sleeve 2 is always located on the right side of the embedded main pipe 1 to maintain stable movement in the horizontal direction.

[0031] See also Figure 3 , wherein: a rubber strip 18 is fixedly connected to the limiting plate 9 , and the rubber strip 18 is located on a side of the limiting plate 9 away from the rotating shaft 8 .

[0032] In the present invention, when the limiting plate 9 moves toward the inner wall of the drill hole, the rubber strip 18 will first fit with the inner wall of the drill hole. The deformed rubber strip 18 can increase the friction with the inner wall of the drill hole, thereby improving the stability between the rubber strip 18 and the template.

[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
