The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0027] Combined with Figure 1 、 Figure 2 and Figure 3As shown, a device for densely pouring the top of a structural column under a slab includes a main body 1, an armrest 8 is arranged on the main body 1, a pouring port 3 is arranged on one side of the main body 1, a sealing mechanism 4 is arranged on the pouring port 3, and a pushing plate mechanism 2 for extruding concrete to enter the formwork of the structural column from the pouring port 3 is arranged on the other side of the main body 1. Specifically, a device for densely pouring the top of a structural column under a slab. The design goal of this device is to ensure that the concrete can enter the formwork of the structural column evenly and without air bubbles, so as to achieve dense pouring at the top of the column. The main body 1 serves as the basic structure of the entire device and bears the weights of components such as the pushing plate mechanism 2 and the sealing mechanism 4. The main body 1 should be made of strong and durable materials, such as high-strength steel or alloy materials. Appropriate space should be designed inside the main body 1 to facilitate the smooth flow of concrete under the push of the pushing plate mechanism 2. The armrest 8 is installed on the main body 1 to facilitate the operator to move and position the device. The armrest 8 should have an anti-slip design to ensure the safety of the operator during operation. The pouring port 3 is located on one side of the main body 1 and is the passage for the concrete to enter the formwork of the structural column. The pouring port 3 should be designed large enough to ensure the smooth flow of the concrete, but not too large to prevent segregation of the concrete during the flow process. The sealing mechanism 4 is used to close the pouring port 3 before pouring the concrete to prevent impurities from entering. During the pouring of the concrete, the sealing mechanism 4 should be able to open quickly and completely to ensure that the concrete can smoothly enter the pouring port 3. The sealing mechanism 4 should have reliable sealing performance to prevent the leakage of the concrete during the pouring process. The pushing plate mechanism 2 is installed on the other side of the main body 1 and is used to push the concrete to enter the formwork of the structural column from the pouring port 3. The pushing plate mechanism 2 should have sufficient thrust to ensure that the concrete can enter the formwork evenly and without air bubbles. The pushing plate mechanism 2 should be designed with an adjustment mechanism to adjust the moving speed and thrust of the pushing plate according to actual needs. Through the above design, this device for densely pouring the top of a structural column under a slab can achieve efficient, uniform and dense pouring of the concrete, improving the construction quality and efficiency of the structural column.
[0028] Combined with Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the sealing mechanism 4 includes fixed baffles 41 arranged on both sides of the pouring opening 3, and a sliding baffle 42 is slidably installed on the fixed baffles 41. Specifically, the sealing mechanism 4 includes fixed baffles 41 arranged on both sides of the pouring opening 3 and a sliding baffle 42 slidably installed on the fixed baffles 41. Such a design can ensure that when concrete needs to be poured, the sliding baffle 42 can smoothly open or close the pouring opening 3. The fixed baffles 41 are installed on both sides of the pouring opening 3 to fix the sliding track of the sliding baffle 42. It should be made of strong and durable materials to ensure its stability and durability. A chute or guide rail can be provided on the inner side of the fixed baffle 41 so that the sliding baffle 42 can slide smoothly on it. The sliding baffle 42 is installed on the chute or guide rail of the fixed baffle 41 and can move horizontally along its sliding track. When the sliding baffle 42 is completely closed, it should be able to fit tightly with the fixed baffle 41 to effectively seal the pouring opening 3 and prevent impurities from entering. When concrete needs to be poured, the sliding baffle 42 can slide outward along the chute or guide rail to open the pouring opening 3. To facilitate the operation of the sliding baffle 42, an operating mechanism such as a handle, a lever or an electric drive can be provided. The operating mechanism should be installed in an easily operable position and designed to be strong enough to easily open or close the sliding baffle 42 when needed. To ensure that the sliding baffle 42 can remain stable in the closed state, a locking device such as a locking bolt, a buckle or a spring lock can be provided. The locking device should be able to firmly fix the sliding baffle 42 to prevent it from accidentally opening when not needed. When designing the sealing mechanism 4, safety factors should be fully considered. For example, an anti-pinch design can be provided at the edge of the sliding baffle 42 to prevent the operator from being pinched during use. In addition, eye-catching safety warning signs should also be provided on the device to remind the operator of safety matters. Since the sealing mechanism 4 needs to be opened and closed frequently, wear-resistant and corrosion-resistant materials should be selected to manufacture the sliding baffle 42 and the fixed baffle 41 to ensure its long-term use stability and durability. Through the above design, it can be ensured that the sealing mechanism 4 can effectively seal or open the pouring opening 3 when needed, thus ensuring the quality and efficiency of concrete pouring.
[0029] Combined with Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, grooves 411 formed by opposite flanges are provided at the upper and lower ends of the fixed baffle 41, and the sliding baffle 42 can slide and be pulled out within the grooves 411. Specifically, grooves 411 formed by opposite flanges are provided at the upper and lower ends of the fixed baffle 41, providing a clear sliding path and stable support for the sliding baffle 42. Such a design can ensure that the sliding baffle 42 remains stable during the pulling process and can effectively seal the pouring opening 3. The fixed baffle 41 is installed on both sides of the pouring opening 3 to ensure that the sliding baffle 42 can slide in the correct position. Grooves 411 are provided at the upper and lower ends, and the width of the grooves 411 should match the thickness of the sliding baffle 42 so that the sliding baffle 42 can slide smoothly therein. The design of the grooves 411 can also provide additional support for the sliding baffle 42 to prevent it from shifting or wobbling during the sliding process. The sliding baffle 42 is installed within the grooves 411 of the fixed baffle 41 and can slide along the direction of the grooves 411. When the sliding baffle 42 is fully inserted into the grooves 411, it should be able to fit tightly against the fixed baffle 41, thereby effectively sealing the pouring opening 3. To ensure that the sliding baffle 42 can remain stable in the closed state, a locking device such as a locking bolt, buckle, or spring lock can be provided on its side or top. The locking device should be able to firmly fix the sliding baffle 42 to prevent it from accidentally opening when not needed. The fixed baffle 41 and the sliding baffle 42 should be made of corrosion-resistant and wear-resistant materials such as stainless steel or carbon steel with surface treatment. These materials can not only provide sufficient strength and durability but also ensure that they will not fail due to corrosion or wear during long-term use. When operating the sliding baffle 42, it should be ensured that the operator's hands or other body parts do not come into contact with the pouring opening 3 or other parts that may cause harm. An anti-slip design can be provided on the operating handle or grip of the sliding baffle 42 to prevent accidental slipping during operation. Through the above design, the sealing mechanism 4 can ensure that the pouring opening 3 can be effectively sealed or opened when needed, while providing stable support and easy operation characteristics. This helps to improve the quality and efficiency of concrete pouring and ensure the safety of the construction process.
[0030] Combined with Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a handle 421 is provided on the sliding baffle 42. Specifically, the sliding baffle 42 needs to be frequently pulled by the operator to open or close the pouring opening 3. Setting a handle 421 on the sliding baffle 42 will greatly improve the convenience and efficiency of operation. The sliding baffle 42 should be able to slide smoothly within the groove 411 of the fixed baffle 41 to ensure the sealing of the pouring opening 3. The material of the sliding baffle 42 should be selected as corrosion-resistant, wear-resistant and strong enough, such as stainless steel or high-strength alloy, to ensure its stability and reliability during long-term use. The handle 421 should be firmly fixed on the sliding baffle 42, which can be by welding, bolt connection or other reliable connection methods. The shape and size of the handle 421 should be designed to be convenient for the operator to grasp, so as to ensure that force can be easily applied when pulling the sliding baffle 42. The surface of the handle 421 should be anti-slip treated, such as adding texture or using anti-slip material, to prevent slipping during operation. If possible, some designs to increase friction can be set on the handle 421 to further improve the stability and safety of operation. The setting of the handle 421 should enable the operator to stand in a safe and comfortable position and open or close the pouring opening 3 through a simple pulling action. The position and angle of the handle 421 should be designed reasonably so that the operator can maintain body balance when pulling the sliding baffle 42 and avoid accidents. During operation, it should be ensured that the operator's hands or other body parts do not touch the pouring opening 3 or other parts that may cause harm. If possible, some protection devices to prevent pinching hands, such as spring buffers or limit switches, can be set between the sliding baffle 42 and the fixed baffle 41. Regularly check whether the connection between the handle 421 and the sliding baffle 42 is firm, and tighten it in time if it is loose. Regularly clean the surfaces of the handle 421 and the sliding baffle 42 to remove impurities such as dust and oil stains and keep them in good working condition. Through the above design, the handle 421 on the sliding baffle 42 will greatly improve the convenience and safety of the operator during the process of pouring concrete.
[0031] Combined with Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the push plate mechanism 2 includes a first movable push plate 5 hinged to the bottom of the main body 1. One end of the first movable push plate 5 is hinged to a second movable push plate 6, and one end of the second movable push plate 6 is hinged to a rotating rod 7. Specifically, the design of the push plate mechanism 2 is to effectively push the concrete from the pouring opening 3 into the structural column formwork. This design realizes the pushing of the concrete by using the lever principle and hinge connections, while ensuring the flexibility and efficiency of the operation. The first movable push plate 5 is the main component of the push plate mechanism 2. It is hinged to the bottom of the main body 1, allowing it to rotate around the hinge point. The length and width of the first movable push plate 5 should be determined according to actual needs to ensure that it can cover the pouring opening 3 and effectively push the concrete. The surface of the first movable push plate 5 can be made of wear-resistant and corrosion-resistant materials to improve its service life and durability. The second movable push plate 6 is hinged to one end of the first movable push plate 5 and can rotate relative to the first movable push plate 5. The design of the second movable push plate 6 can increase the flexibility of the push plate mechanism, enabling it to better adapt to structural column formworks of different shapes and sizes. Similarly, the surface of the second movable push plate 6 should also be made of wear-resistant and corrosion-resistant materials. The rotating rod 7 is hinged to one end of the second movable push plate 6 and is the operating part of the push plate mechanism 2. The operator can drive the rotation of the first movable push plate 5 and the second movable push plate 6 by rotating the rotating rod 7, thereby realizing the pushing of the concrete. The length and shape of the rotating rod 7 should be designed according to actual needs to ensure that the operator can easily operate and apply sufficient force to push the concrete. When concrete needs to be poured, first, the sliding baffle 42 is withdrawn from the pouring opening 3 to open the pouring opening 3. The operator pours the concrete into the main body 1. Push the second movable plate 6 to drive the rotation of the first movable push plate 5, thereby pushing the concrete from the pouring opening 3 into the structural column formwork. The operator can adjust the rotation speed and force of the rotating rod 7 according to needs to ensure that the concrete can enter the structural column formwork evenly and without bubbles. When the concrete pouring is completed, the operator can reinsert the sliding baffle 42 into the pouring opening 3 to close the pouring opening 3. Through this design, the push plate mechanism 2 can flexibly adapt to different structural column formworks and effectively push the concrete into the formwork to ensure the density of the pouring.
[0032] Combined with Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a slide rail 9 is provided on the handrail 8, and both ends of the rotating rod 7 are slidably connected to the slide rail 9. Specifically, by providing the slide rail 9 on the handrail 8 and slidably connecting both ends of the rotating rod 7 to the slide rail 9, such a design not only increases the flexibility of operation but also enables the operator to more easily control the movement of the rotating rod 7, thereby precisely controlling the pushing of the concrete by the push plate mechanism 2. The handrail 8, as an important part of the entire device, in addition to providing convenience for the operator to move and position the device, now also has an installation position for the slide rail 9 added. The material of the handrail 8 should be strong and durable, capable of withstanding the force generated by the operator when pushing the rotating rod 7. The shape and size of the handrail 8 should be designed in accordance with ergonomic principles to facilitate the operator's grasping and operation. The slide rail 9 is installed on the handrail 8 to support and guide the movement of the rotating rod 7. The slide rail 9 should have high precision and smoothness to ensure that the rotating rod 7 can maintain a stable movement trajectory during the sliding process. The length and position of the slide rail 9 should be designed according to actual needs to ensure that the operator can easily control the movement of the push plate mechanism 2 by sliding the rotating rod 7. Both ends of the rotating rod 7 are slidably connected to the slide rail 9, enabling the operator to drive the movement of the push plate mechanism 2 by sliding the rotating rod 7. The connection between the rotating rod 7 and the slide rail 9 should be firm and reliable to ensure that it will not loosen or fall off during operation. Some limiting devices, such as limit blocks or limit switches, can be provided between the rotating rod 7 and the slide rail 9 to limit the sliding range of the rotating rod 7 and prevent it from exceeding the safe range. When concrete needs to be poured, the operator first withdraws the sliding baffle 42 from the pouring port 3 to open the pouring port 3. The operator pours the concrete into the main body 1 and then holds the rotating rod 7 on the handrail 8. The operator drives the rotation of the first movable push plate 5 and the second movable push plate 6 by sliding the position of the rotating rod 7 on the slide rail 9, thereby pushing the concrete to enter the structural column formwork from the pouring port 3. The operator can adjust the position of the rotating rod 7 on the slide rail 9 as needed, as well as the force applied to the rotating rod 7, to precisely control the movement of the push plate mechanism 2 and ensure that the concrete can enter the structural column formwork evenly and without bubbles. When the concrete pouring is completed, the operator can reinsert the sliding baffle 42 into the pouring port 3 to close the pouring port 3. Such a design makes the operation of the push plate mechanism 2 more flexible and precise, improving the quality and efficiency of concrete pouring.
[0033] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a bracket 10 is provided at the bottom of the main body 1. Specifically, setting the bracket 10 at the bottom of the main body 1 is an important design decision, which enhances the stability and support capacity of the overall structure. The bracket 10 should be designed to be strong and stable enough to support the weight of the entire main body 1 and the push plate mechanism 2, and withstand the impact force that may occur during the concrete pouring process. High-strength materials can be used to manufacture the bracket 10 to ensure its structural strength. To adapt to different working environments and ground conditions, the bracket 10 should have a certain degree of adjustability. For example, the legs of the bracket 10 can be designed to be telescopic or foldable to adjust the height or length as needed. To prevent the bracket 10 from sliding or moving during use, anti-slip pads or anti-slip feet can be provided at its bottom. These anti-slip designs can increase the friction between the bracket 10 and the ground, thereby improving its stability. The bracket 10 can be connected to the main body 1 by bolts, welding or other fixing methods to ensure its stability and reliability. If it is necessary to fix the bracket 10 on the ground, anchor bolts or other fixing devices can also be used to firmly fix it to the ground. The design of the bracket 10 should consider its compatibility with the main body 1 and other components. It should be able to match the structure at the bottom of the main body 1 and allow the push plate mechanism 2 and other components to be installed and operated in the correct positions. The main function of the bracket 10 is to provide stable support, ensuring that the main body 1 and the push plate mechanism 2 can maintain a stable position and state, so as to smoothly carry out the concrete pouring work. It can also increase the stability and durability of the overall structure, improve the service life and safety of the equipment. By reasonably designing and manufacturing the bracket 10, it can be ensured that the entire equipment remains stable and safe during use, and the quality and efficiency of concrete pouring are improved.
[0034] Combined with Figure 1 and Figure 2As shown, both the main body 1 and the bracket 10 are made of steel. Specifically, both the main body 1 and the bracket 10 are made of steel, which will provide higher strength, durability and stability, and are suitable for withstanding heavy loads and harsh working environments. Select steel with high strength, good weldability and corrosion resistance, such as carbon steel, low-alloy high-strength steel or stainless steel. According to the specific use environment and load requirements, select the appropriate steel thickness and cross-sectional shape. Design a reasonable beam, column and plate structure to ensure that the main body 1 and the bracket 10 have sufficient strength and stiffness to withstand various forces and pressures during the concrete pouring process. The cross-sectional shape and size of the steel should be optimized according to the stress conditions to achieve the best load-bearing performance. Adopt connection methods such as welding, bolt connection or riveting to ensure the firm and reliable connection between steel components. For important connection points, such as the connection between the main body 1 and the bracket 10, high-strength connection methods and materials should be used, and strict inspection and testing should be carried out. For steel that is exposed to the outdoor or humid environment for a long time, anti-corrosion treatment should be carried out, such as spraying anti-rust paint or using hot-dip galvanizing. Anti-corrosion treatment can improve the corrosion resistance of steel and extend its service life. Treat the steel surface by grinding, rust removal and painting to improve its appearance quality and corrosion resistance. Select the appropriate coating type and color according to the working environment and requirements. The design of the main body 1 and the bracket 10 should comply with relevant safety standards and specifications to ensure safety during use. For possible safety hazards, such as sharp edges, protruding parts or easily sliding parts, corresponding safety protection measures should be taken, such as installing protective covers and setting anti-slip patterns. Regularly check whether the structures of the main body 1 and the bracket 10 are intact, and repair or replace them in time if there are damages or deformations. Regularly clean and remove rust from the steel surface to maintain its good appearance and corrosion resistance. During use, avoid overloading or improper operation to avoid excessive stress and damage to the steel. Through the above design considerations and measures, the main body 1 and the bracket 10 made of steel will have higher strength, durability and stability, and can meet the use requirements of the concrete pouring equipment in various working environments.
[0035] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
