Description

A concrete pouring splash prevention device Technical Field

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

[0002] In the field of construction, concrete pouring is a crucial process, widely used in the construction of foundations, walls, floors, and other parts of various building structures. However, during the concrete pouring process, the high-speed flow of concrete from the mixer truck or pump pipe easily causes splashing. This splashed concrete not only seriously pollutes the construction site environment, causing concrete stains to cover the ground, equipment, and surrounding building surfaces, increasing the subsequent cleaning workload and costs, but also poses a threat to the personal safety of construction workers, such as injury caused by splashed concrete particles getting into the eyes or skin.

[0003] To address the issue of splashing during concrete pouring, some splash-proof devices have emerged on the market. However, most existing splash-proof devices have numerous shortcomings. On the one hand, some splash-proof devices have complex structures and cumbersome assembly processes, requiring a significant amount of manpower and time for installation and disassembly. This not only reduces construction efficiency but also makes it difficult to meet the need for rapid construction of splash barriers when faced with time-sensitive construction tasks. For example, some splash-proof devices require the use of various special tools and complex steps to assemble and fix multiple components, requiring construction personnel to undergo extensive training to master the operation methods.

[0004] On the other hand, some splash guards have limited protective effects and cannot effectively block large-scale splashing of concrete. At the same time, the devices themselves are easily damaged under the continuous impact of concrete and have a short service life. For example, some splash guards use a single-layer thin plate structure. Under the high pressure impact of concrete, the thin plate is easy to deform and crack, losing its splash guard function. Moreover, existing splash guards also have certain problems in terms of movement and stability. They are inconvenient to move and difficult to quickly adjust to a suitable pouring position. They are also prone to shaking due to external forces during the pouring process, affecting the splash guard effect.

[0005] To address the aforementioned issues, we propose a concrete pouring splash prevention device. Summary of the Invention

[0031] Structural Description:

[0032] 1. Mounting Ring: The mounting ring is the basic load-bearing structure of the concrete pouring splash guard. It is ring-shaped and usually made of a strong metal material, such as steel, to ensure that it has sufficient strength and stability to support the entire device. The lower part of its interior is provided with a sloping groove. This sloping groove is designed for precise positioning and installation of the lower splash guard, so that the lower splash guard can be firmly locked in it, becoming the bottom protective structure of the entire splash guard system. It is an indispensable basic frame part of the device.

[0033] 2. Fixing Ring: The fixing ring is a ring structure, installed inside the mounting ring at the upper end of the lower splash guard. It is also made of metal and has good rigidity. Its main function is to connect and fix the upper splash guard and the lower splash guard. Its lower end fits tightly against the upper surface of the lower splash guard. It is fixed to the mounting ring by multiple lower fixing bolts. At the same time, the upper splash guard is installed inside it and further tightened by multiple upper fixing bolts to ensure the stability of the entire splash guard structure. It is a key structural component for connecting the upper and lower splash guards.

[0034] 3. Upper splash guard: The upper splash guard is composed of multiple conical plates spliced ​​together. As the splash guard structure at the top of the device, it is mainly used to block concrete from splashing upwards. The conical plates are generally made of thin metal plates or high-strength engineering plastic materials with certain strength and toughness. They can effectively resist the impact of concrete and are relatively lightweight. When splicing, the connecting column set on one side of the conical plate cooperates with the circular groove on the other side of the adjacent conical plate to achieve a tight connection, thereby forming a complete splash guard plane covering the top of the device, providing reliable splash protection for the area above.

[0035] 4. Lower splash guard: The lower splash guard is also composed of multiple conical plates spliced ​​together and installed in the inclined groove inside the mounting ring. Its inclined installation method, together with the upper splash guard, forms a comprehensive splash protection system. It is mainly used to guide the flow of concrete and reduce its initial splash. The conical plates of the lower splash guard are made of similar material to the upper splash guard and are spliced ​​and assembled through connecting columns and circular grooves. During the concrete pouring process, its unique inclined structure can effectively change the splash direction of concrete and reduce the splash height. It is an important bottom protective component of the splash protection device.

[0036] 5. Support rod: The support rod is the supporting structure of the device. It is usually made of metal tubing, such as stainless steel tubing, which has high strength. Its lower end is fixedly connected to the casters, and its upper end is connected to the main body of the device. After the device is moved to the concrete pouring area, the support rod vertically supports the entire device, ensuring that the device remains stable during the pouring process and will not shake or shift due to external forces, thus providing reliable support for the splash-proof device.

[0037] 6. Casters: Casters are installed at the lower end of the support rod and serve as the moving parts of the device. They are made of high-strength rubber or wear-resistant materials such as polyurethane and are equipped with a flexible steering mechanism. This design allows the device to be moved easily on the construction site. Construction workers can easily push the device to the designated location according to the needs of the concrete pouring position, which greatly improves the mobility and ease of use of the device.

[0038] 7. Buffer pad: The buffer pad is installed between the fixing ring and the upper splash plate. It is generally made of materials with good elasticity and buffering performance, such as rubber or silicone. Its main function is to absorb and buffer the impact force when concrete splashes hit the upper splash plate, reduce the direct impact of concrete on the upper splash plate, thereby reducing the risk of damage to the upper splash plate due to long-term impact, extending the service life of the upper splash plate, and also helping to improve the splash protection effect of the entire splash protection device.

[0039] 8. Upper fixing bolt: The upper fixing bolt is made of metal, usually stainless steel, and is used to fix the upper splash guard inside the fixing ring. One end of the bolt passes through the buffer pad from the outside of the fixing ring and is tightly connected to the upper splash guard. By tightening the nut, the upper splash guard is firmly fixed to the fixing ring, ensuring that the upper splash guard will not loosen due to impact or vibration during the concrete pouring process, and maintaining the splash protection performance of the device.

[0040] 9. Lower fixing bolt: The lower fixing bolt is made of the same material as the upper fixing bolt and is used to fix the fixing ring and the mounting ring together. It passes through the corresponding mounting holes on the fixing ring and the mounting ring and is tightened by the nut, so that the fixing ring can be stably installed on the mounting ring, thereby fixing the lower splash guard and ensuring the integrity and stability of the entire splash guard structure.

[0041] 10. Positioning pin: The positioning pin is generally made of metal and is installed on the outer side of the fixing ring. Its lower end penetrates vertically through the surface of the fixing ring and connects with the mounting ring. It mainly plays the role of precise positioning and limiting. When the fixing ring is installed on the mounting ring, the positioning pin ensures that the position of the fixing ring is accurate and prevents the fixing ring from shifting during the use of the device, thereby further enhancing the stability of the device structure.

[0042] 11. Connecting Post: The connecting post is a cylindrical structure set on one side of the conical plate. It is usually made of metal or high-strength plastic. Its diameter and length are designed according to the size of the conical plate and the connection requirements. It is used to connect with the circular groove on the other side of the adjacent conical plate. When assembling the upper splash guard and the lower splash guard, the connecting post is inserted into the circular groove to achieve a tight splicing between the conical plates, thereby constructing a complete splash guard structure.

[0043] 12. Circular groove: The circular groove is located on the other side of the conical plate, corresponding to the connecting column. Its size is precisely matched with the connecting column. It is used to receive the connecting column and realize the connection between the conical plates. The depth and inner diameter of the circular groove are designed according to the size of the connecting column to ensure the firmness and stability of the connection. It is one of the key connection structures for splicing conical plates into splash guards.

[0044] 13. Conical Plate: The conical plate is the basic unit that makes up the upper and lower splash guards. It is conical in shape and has unique flow guiding and blocking functions. Its material can be thin metal sheet or high-strength engineering plastic, which can ensure a certain strength to resist the impact of concrete, while having a relatively light weight, making it easy to assemble and transport. Multiple conical plates are connected to each other by connecting columns and circular grooves to form upper and lower splash guards with specific shapes and protection ranges, playing a core protective role in the process of concrete pouring splash prevention.

[0045] 14. Movable Cover: The movable cover is hinged to the upper end of the fixed block. Its overall shape is adapted to the fixed block. It is usually made of metal and has a certain strength and rigidity. Its surface is provided with limit blocks that match the T-slots on the fixed block to control the movement of the T-slots. When the device needs to be moved, the movable cover can be opened to allow the T-slots to move freely. When the device is in fixed use, the movable cover is closed, and the movement of the T-slots is restricted by the limit blocks and limit posts to ensure the support stability of the device.

[0046] 15. T-block: The T-block is a key component used to connect the support rod and the fixed block. It is made of metal and is T-shaped. Its horizontal part is fixedly connected to the lower end of the support rod, and its vertical part is installed in the T-slot inside the fixed block. Through the cooperation of the T-block and the T-slot, the support rod and the fixed block can be moved and connected, so that the device can be flexibly adjusted when moving and can provide stable support when fixed.

[0047] 16. Limiting block: The limiting block is set on the surface of the movable cover. It is a block structure and is usually made of the same material as the movable cover. Its shape and size match the T-slot on the fixed block. When the movable cover is closed, the limiting block can be locked into a specific position in the T-slot, limiting the movement range of the T-slot within the T-slot. This prevents the device from becoming unstable due to the movement of the T-slot during use, ensuring the safety and stability of the device.

[0048] 17. Fixing Block: The fixing block is an important structure for connecting and fixing related components. It is generally made of metal and has high strength and stability. It has a T-slot inside for installing T-blocks to connect with the support rod. At the same time, a movable cover is installed at its upper end through a hinge. The movement of the T-block is controlled by the movable cover and the limiting block. The fixing block plays a key role in connecting and supporting the device, ensuring stable connection and coordinated operation between the various components of the device.
