Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a concrete pouring control device. Background Technology

[0002] Concrete pouring control devices are key equipment used in construction projects to ensure the quality, efficiency, and safety of concrete pouring. During the concrete pouring process, the ends of the pouring pipe often drip due to concrete residue or pressure changes, polluting the construction area and wasting materials. In existing technologies, manual cleaning or simple trays are usually used to catch the dripping concrete, but these methods have limitations such as inconvenient operation, low cleaning efficiency, and unstable fixing.

[0003] The reason for this problem is that dripping cement accumulates on the formwork or reinforcing bars, forming a weak layer that leads to cold joints at the interface between new and old concrete, reducing the shear strength of the structure. Unexpected dripping can also cause unevenness on the structural surface, increasing the workload of subsequent finishing. Traditional methods require workers to frequently climb to heights to clean up dripping cement, which poses a risk of falls from heights and increases the accident rate, thus having limitations. Therefore, we propose a concrete pouring control device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete pouring control device, which solves the problem that during the concrete pouring process, the end of the pouring pipe often drips due to concrete residue or pressure changes, polluting the construction area and causing material waste. In existing technologies, manual cleaning or simple trays are usually used to catch the dripping concrete, but these methods have limitations such as inconvenient operation, low cleaning efficiency, and unstable fixing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a concrete pouring control device, including a pouring pipe, wherein the end of the pouring pipe is provided with a receiving unit for preventing concrete dripping, the receiving unit including a retaining ring, a fixing member and a receiving basket;

[0006] The retaining ring is composed of two semi-circular hinges; the fixing member is located inside the retaining ring and is used to install the retaining ring on the pouring pipe; the receiving basket is located below the retaining ring, and the end of the receiving basket abuts against the end of the retaining ring and is used to collect concrete dripping from the pouring pipe.

[0007] Preferably, the retaining ring has a groove inside, the groove has a tapering structure from top to bottom, and the side of the retaining ring near the casting pipe is made of elastic material.

[0008] Preferably, the inner wall of the retaining ring is provided with a wear-resistant plate, and the wear-resistant plate is in close contact with the casting pipe.

[0009] Preferably, a scraper is provided below the wear-resistant plate, and the scraper is used to scrape off the cement adhering to the outer surface of the casting pipe.

[0010] Preferably, the fixing element includes a stop, a slider, and a connecting post;

[0011] The stop block is mounted on the retaining ring; the slider is slidably connected inside the groove; and the connecting post is slidably connected inside the slider.

[0012] Preferably, the fixing element further includes a spring and an arc-shaped block;

[0013] The spring is wound around the outer surface of the connecting column, one end of the spring is fixedly assembled with the slider, and the other end of the spring is fixedly assembled with the connecting column; the arc-shaped block is fixedly assembled at the bottom of the connecting column, and the arc-shaped block is used to push the wear-resistant sheet to press towards the casting pipe.

[0014] Preferably, a rod is fixedly mounted on the receiving basket, the rod passes through the retaining ring and the stop block, and a first nut is threaded onto the outer surface of the rod, the end of the first nut abutting against the outer surface of the stop block.

[0015] Preferably, a protrusion is fixedly mounted on one side of the retaining ring, the protrusions are symmetrically arranged, a threaded rod passes through the inside of the protrusion, and a second nut is threadedly fitted on the outer surface of the threaded rod, the second nut abutting against the protrusion.

[0016] This utility model discloses the following beneficial effects of a concrete pouring control device: By incorporating a receiving unit, the device effectively collects concrete dripping from the end of the pouring pipe, avoiding material waste and environmental pollution caused by concrete dripping. As the amount of concrete collected in the receiving basket increases and its weight rises, a downward pulling force is generated on the stop block via the insert rod. Since the stop block is connected to the slider, this pulling force causes the slider to slide downwards in a tapered groove, which in turn pushes the wear-resistant plate to fit more tightly against the surface of the pouring pipe through the connecting column and the arc-shaped block. This design ensures that the heavier the receiving basket, the greater the tightening force of the fastener on the retaining ring, creating a dynamic, self-adaptive tightening effect. This significantly improves the stability of the device during long-term use, making it particularly suitable for high-flow, long-duration concrete pouring operations. Attached Figure Description

[0026] Example 1

[0027] This utility model discloses a concrete pouring control device. According to the appendix... Figure 1-2 As shown, it includes a pouring pipe 1, and the end of the pouring pipe 1 is provided with a receiving unit 2 for preventing concrete from dripping. The receiving unit 2 includes a retaining ring 21, a fastener 22 and a receiving basket 23.

[0028] The retaining ring 21 is composed of two semi-circular hinges; the fixing member 22 is located inside the retaining ring 21 and is used to install the retaining ring 21 on the pouring pipe 1; the receiving basket 23 is located below the retaining ring 21, and the end of the receiving basket 23 abuts against the end of the retaining ring 21. The receiving basket 23 is used to collect the concrete dripping from the pouring pipe 1.

[0029] The retaining ring 21 has a groove 24 inside, which has a tapering structure from top to bottom. The side of the retaining ring 21 near the casting pipe 1 is made of elastic material. The inner wall of the retaining ring 21 is provided with a wear-resistant plate 25, which fits tightly with the casting pipe 1. A scraper 26 is provided below the wear-resistant plate 25. The scraper 26 is used to scrape off the cement adhering to the outer surface of the casting pipe 1. A plug rod 27 is fixedly installed on the receiving basket 23. The plug rod 27 passes through the retaining ring 21 and the stop block 221. The outer surface of the plug rod 27 is threaded with a first nut 28. The end of the first nut 28 abuts against the outer surface of the stop block 221. A protrusion 29 is fixedly installed on one side of the retaining ring 21. The protrusions 29 are symmetrically arranged. A threaded rod 210 passes through the inside of the protrusion 29. The outer surface of the threaded rod 210 is threaded with a second nut 211, which abuts against the protrusion 29.

[0030] In this embodiment, the two semi-circular hinged retaining rings 21 are opened and placed on the pouring pipe 1. The retaining rings 21 are pulled down so that the scraper 26 on the retaining rings 21 abuts against the pouring pipe 1. The scraper 26 scrapes off the cement adhering to the pouring pipe 1. Then the retaining rings 21 are pulled up and fixed to the pouring pipe 1 by the threaded rod 210 and the second nut 211. The insert rod 27 is inserted into the inside of the stop block 221 and tightened by the first nut 28 so that the receiving basket 23 is connected to the retaining rings 21.

[0031] Example 2

[0032] This utility model discloses a concrete pouring control device. More specifically, based on Embodiment 1, it includes a device according to the appendix... Figure 1 , 3 As shown in Figure 4, the concrete includes a pouring pipe 1, and a receiving unit 2 for preventing concrete from dripping is provided at the end of the pouring pipe 1. The receiving unit 2 includes a retaining ring 21, a fastener 22, and a receiving basket 23.

[0033] The retaining ring 21 is composed of two semi-circular hinges; the fixing member 22 is located inside the retaining ring 21 and is used to install the retaining ring 21 on the pouring pipe 1; the receiving basket 23 is located below the retaining ring 21, and the end of the receiving basket 23 abuts against the end of the retaining ring 21. The receiving basket 23 is used to collect the concrete dripping from the pouring pipe 1.

[0034] The fixing component 22 includes a stop block 221, a slider 222, and a connecting post 223; the stop block 221 is disposed on the retaining ring 21; the slider 222 is slidably connected to the inside of the slide groove 24; the connecting post 223 is slidably connected to the inside of the slider 222; the fixing component 22 also includes a spring 224 and an arc-shaped block 225; the spring 224 is wound around the outer surface of the connecting post 223, one end of the spring 224 is fixedly assembled with the slider 222, and the other end of the spring 224 is fixedly assembled with the connecting post 223; the arc-shaped block 225 is fixedly assembled at the bottom of the connecting post 223, and the arc-shaped block 225 is used to push the wear-resistant plate 25 towards the direction of the casting pipe 1.

[0035] In this embodiment, as the amount of concrete collected in the receiving basket 23 gradually increases and its weight increases, the insert rod 27 generates a downward pulling force on the stop block 221. Since the slide groove 24 has a tapered structure from top to bottom, when the slider 222 slides downward in the slide groove 24, it pushes the connecting column 223 and the arc-shaped block 225 towards the pouring pipe 1, thereby causing the wear-resistant plate 25 to fit tightly against the pouring pipe 1. Simultaneously, the spring 224 is compressed, generating elastic force, further strengthening the fastening effect between the retaining ring 21 and the pouring pipe 1. This meets the user's needs.
