In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0026] The following will be combined with Figure 1 Describe the continuous beam concrete placing device of the present utility model.

[0027] The embodiments of the present utility model provide a continuous beam concrete placing device, including a funnel 1 and a pouring pipe 2.

[0028] Among them, both the top side and the bottom side of the funnel 1 are open, facilitating the loading and discharging of concrete. The funnel 1, as the initial container for concrete placing, can concentrate and guide the concrete to flow towards the pouring pipe 2, effectively reducing the splashing and waste of concrete in the initial stage. The top end of the pouring pipe 2 is connected to the bottom of the funnel 1, and the bottom end of the pouring pipe 2 allows the concrete to flow out, forming a concrete flow channel.

[0029] In addition, the distance between the bottom end of the pouring pipe 2 and the bottom side of the continuous beam is a, where 0 < a ≤ 1 m, and the top end of the pouring pipe 2 protrudes beyond the top side of the continuous beam 3 and the distance from the top side of the continuous beam is b, where 0 < b ≤ 50 cm. During use, after the continuous beam body steel bars 4 are bound and installed, the pouring pipe 2 is pre-embedded along the longitudinal direction at the position of the continuous beam web. A funnel 1 is provided at the top of the pouring pipe 2. When pouring concrete, the concrete is pumped to the funnel 1 and lowered along the pouring pipe 2 into the beam body, thereby reducing the free fall of the concrete and avoiding segregation during the concrete pouring process, ensuring the workability of the concrete.

[0030] It should be noted that the concrete can also fall into the continuous beam body at a relatively gentle angle, avoiding segregation caused by excessive impact, and at the same time reducing the direct impact of the concrete on the formwork and protecting the integrity of the formwork.

[0031] The top end of the pouring pipe not only protrudes beyond the top side 3 of the continuous beam, but also maintains a certain distance b (0 < b ≤ 50 cm) from the top side 3 of the continuous beam. Such a design facilitates the operator to control the height and angle of the pouring pipe 2, thereby more precisely controlling the flow direction and distribution of the concrete. At the same time, it also makes the pouring process more flexible and can adapt to the pouring requirements of beam bodies with different heights and widths.

[0032] By precisely controlling the settings of the distances a and b between the pouring pipe 1 and the continuous beam, this device can ensure that the concrete flows into the beam body at a uniform and stable speed, reducing the segregation and stratification phenomena of the concrete during the pouring process and improving the pouring quality.

[0033] The protruding design of the top end of the pouring pipe 2 enables the operator to more conveniently adjust the height and angle of the pouring pipe 2 to adapt to different pouring requirements. In addition, the entire tooling structure is simple, easy to assemble and disassemble, and is convenient for rapid deployment and adjustment at the construction site.

[0034] Since the concrete can flow accurately and quickly into the beam body, it reduces the time waste caused by repeatedly adjusting the pouring position and speed, and improves the construction efficiency.

[0035] In a feasible embodiment of the present utility model, the pouring pipe 2 includes a PE pipe. The PE pipe has excellent corrosion resistance and can resist the erosion of a variety of chemical substances, including corrosive media such as acids and alkalis. During the concrete pouring process, the PE pipe can effectively prevent corrosion problems caused by chemical substances in the concrete and ensure the smooth progress of the pouring process. When pouring concrete, the concrete particles and cement slurry will generate certain friction and impact on the inner wall of the pipe. The PE pipe has good wear resistance and can withstand this wear, extending its service life. The PE pipe has certain flexibility and impact resistance and can adapt to the pouring requirements of different shapes and angles. During the continuous beam pouring process, this characteristic enables the PE pipe to better adapt to the complex structure of the beam body and ensure that the concrete can flow smoothly into the designated position. The inner wall of the PE pipe is smooth, which can reduce the resistance of the concrete during the flowing process and improve the pouring efficiency. At the same time, the smooth inner wall also helps to prevent the concrete from accumulating and blocking in the pipe.

[0036] In the above embodiment, the PE pipe is used as the main material of the pouring pipe 2 in the continuous concrete feeding tooling. By reasonably designing parameters such as the length, diameter and connection method of the pouring pipe 2, it can ensure that the concrete can flow accurately and efficiently into the continuous beam body, improving the pouring quality and construction efficiency.

[0037] In a feasible embodiment of the present utility model, the funnel 1 includes a trapezoidal funnel, and the bottom end of the trapezoidal funnel is adapted to the pouring pipe 2. The shape of the trapezoidal funnel helps the concrete material to flow more smoothly inside the funnel. Due to the trapezoidal design, the material can naturally slide down along the inclined plane of the funnel under the action of gravity, reducing the retention and blockage of the material inside the funnel. The bottom of the trapezoidal funnel gradually narrows and is adapted to the diameter of the pouring pipe 2, enabling the concrete to be more concentrated and stable when flowing out of the funnel. This design reduces the diffusion and splashing of the concrete during the outflow process, improving the feeding efficiency. Since the bottom of the trapezoidal funnel is tightly connected to the pouring pipe 2, the leakage and overflow of the concrete at the connection are reduced. This helps to reduce material waste and keep the construction site clean.

[0038] In a feasible embodiment of the present utility model, the trapezoidal funnel is welded from a steel plate with a thickness of 5 mm. The 5-mm-thick steel plate has relatively high strength and stiffness and can withstand the impact and pressure generated during the concrete pouring process. This material strength ensures the stability and safety of the trapezoidal funnel during use, avoiding deformation or damage caused by insufficient strength. The steel plate material has good wear resistance and corrosion resistance and can resist the erosion of sand and gravel particles and chemical substances in the concrete. This durability enables the trapezoidal funnel to withstand long-term use and frequent concrete feeding operations, extending the service life of the device.

[0039] In a feasible embodiment of the present utility model, the funnel 1 includes an annular part 101 and a feeding part 102. The annular part 101 serves as the upper support structure of the funnel, providing a stable base for the entire funnel. The annular part 101 is usually connected to the support structure to ensure that the funnel remains stable and does not shake during the pouring process. The shape and size of the annular part 101 are reasonably designed, capable of bearing the weight of the funnel and the concrete therein, and facilitating the connection and fixation with the support structure. The feeding part 102 is arranged at the bottom of the annular part 101, and the bottom end of the feeding part 102 is detachably connected to the pouring pipe 2. This design brings various conveniences. First, it facilitates the assembly and debugging of the funnel 1 and the pouring pipe 2 before pouring, ensuring a tight connection without leakage. Second, during the pouring process, if it is necessary to replace pouring pipes with different diameters or lengths, or to clean and maintain the funnel, the feeding part 102 can be conveniently disassembled to achieve rapid replacement or maintenance.

[0040] In a feasible embodiment of the present utility model, the circular ring portion 101 and the blanking portion 102 are integrally connected and can be integrally formed into an inseparable unit by casting, forging, molding or other manufacturing processes. Since the two parts are integrated, the connection between them is very strong, without stress concentration points that may be caused by connecting parts, thereby improving the strength and stability of the overall structure. The integral forming manufacturing process is usually simpler and more efficient than the process of separately manufacturing and then assembling, reducing the assembly time and cost. Due to the absence of additional connecting parts in integral forming, the maintenance and replacement requirements caused by the loosening or damage of the connecting parts are reduced. The integral forming design is usually more smooth and beautiful, without gaps or unevenness caused by assembly.

[0041] In a feasible embodiment of the present utility model, the circular ring portion 101 and the blanking portion 102 are welded. Welding can provide very strong connection strength, making the connection part almost have the same strength as the base material. Welding can form a very tight joint, thereby providing good sealing performance to prevent liquid or gas leakage. Welded joints usually have good durability and can maintain their connection performance under various environmental conditions.

[0042] In a feasible embodiment of the present utility model, there are multiple funnels 1 and pouring pipes 2, and the funnels 1 and the pouring pipes 2 are arranged in one-to-one correspondence, which can achieve precise control and distribution of concrete or other materials, ensuring that each pouring point can receive an appropriate amount of materials. Multiple pouring pipes 2 working simultaneously can significantly improve the pouring efficiency and shorten the construction period. The interval distance between every two adjacent pouring pipes 2 is 2 - 3m. A reasonable interval distance and distribution method can reduce material waste and improve the economy of construction.

[0043] According to the construction requirements and site conditions, determine the specific quantities of the funnels 1 and the pouring pipes 2. Each funnel 1 corresponds to a pouring pipe 2 to ensure that the materials can flow smoothly from the funnel 1 into the pouring pipe 2. The interval distance between every two adjacent pouring pipes 2 is 2 - 3m. The setting of this distance needs to consider factors such as the fluidity of the materials, the pouring speed, and the site space. Too close a distance may cause the materials to interfere with each other during pouring, affecting the pouring quality; while too far a distance may increase the construction difficulty and cost.

[0044] In a feasible embodiment of the present utility model, the diameter of the pouring pipe 2 is 160 mm - 200 mm. This size range is determined according to specific requirements when designing the pouring system, aiming to ensure that concrete or other materials can smoothly flow through the pouring pipe into the designated pouring area. Different materials have different fluidities. A wider diameter can accommodate materials with poor fluidity and reduce the risk of blockage. A wider diameter generally allows for a faster pouring speed because more materials can pass through the pipe simultaneously. The pouring pipe needs to match the size and shape of the pouring area to ensure uniform distribution of the materials.

[0045] In a feasible embodiment of the present utility model, the pouring pipe 2 includes a steel pipe. The steel pipe has high strength and stiffness, can withstand the pressure generated during the concrete pouring process, and ensures the stability and safety of the pouring process. The steel pipe has good corrosion resistance and wear resistance, can be used for a long time under various environmental conditions without being easily damaged, thereby extending the service life of the pouring pipe 2. The steel pipe is easy to process and install, and can be cut, welded, and connected according to construction requirements, improving the construction efficiency.

[0046] The continuous beam concrete feeding device provided by the present utility model includes a trapezoidal funnel 1 and a pouring pipe 2. According to the height of the continuous beam web and the steel bar density, the diameter of the pouring pipe 2 is selected to be 160 mm - 200 mm, and the length is selected to be 1 m from the bottom of the continuous beam web and 50 cm above the top of the continuous beam. A funnel 1 adapted to the diameter of the pouring pipe 2 is fabricated by welding a 5 - mm - thick steel plate.

[0047] During use, after the continuous beam body steel bars 4 are tied, a pouring pipe 2 is embedded longitudinally for 2 - 3 m at the position of the continuous beam web. A trapezoidal funnel is provided at the top of the pouring pipe 2. When pouring concrete, the concrete is pumped to the trapezoidal funnel and flows down along the pouring pipe 2 into the continuous beam body, thereby reducing the free fall of the concrete and ensuring the working performance of the concrete.
