Description

Technical Field

[0001] This utility model relates to the field of precast concrete power wall column technology, and more specifically, to a concrete power wall column casting linkage mold system. Background Technology

[0002] In modern construction engineering, the production and application of precast concrete power wall columns are becoming increasingly widespread, and their efficient and standardized manufacturing methods provide important support for building industrialization. However, existing power wall column casting mold systems still have many shortcomings in practical applications, particularly in the ease of mold closing and opening operations, the stability of the mold system, and the structural reliability during the casting process. Traditional mold systems typically adopt a split design, with poor inter-module linkage, resulting in complex and time-consuming mold closing and opening procedures, making it difficult to meet the needs of efficient construction. In addition, during mold operation, the lack of effective limiting and guiding devices makes the system prone to derailment or deviation, thus affecting the positioning accuracy and overall stability of the mold.

[0003] Meanwhile, existing mold systems rely on relatively simple reinforcement measures for the column mold pouring cavity during the pouring process, often depending solely on a simple external support structure. This is insufficient to effectively cope with the lateral pressure generated during concrete pouring, easily leading to mold deformation or loosening, thus affecting the quality of the final formed component. Especially in multi-cavity pouring scenarios, misalignment or leakage is more likely to occur at the joints between adjacent pouring cavities, further reducing construction efficiency and the yield rate of finished products. In addition, the inner and outer wall materials of traditional molds are usually not specially treated, resulting in low surface smoothness and easy adhesion of concrete, increasing the difficulty of demolding and the amount of subsequent cleaning work.

[0004] To address the aforementioned issues, developing a concrete power wall column casting mold system capable of modular, interconnected operation, high stability, and multiple reinforcement measures has become a pressing technical challenge for the industry. By optimizing the mold structure design, enhancing the system's interconnectivity and stability, and improving the sealing and deformation resistance of the casting cavity, the production efficiency and quality of precast power wall columns can be significantly improved, providing more reliable technical support for building industrialization. Utility Model Content

[0005] This invention addresses the problems of complex mold-closing and opening operations, poor operational stability, and easy deformation or loosening during the pouring process in existing precast concrete power wall column casting mold systems. It provides a concrete power wall column casting linkage mold system. The system significantly improves construction efficiency through modular design and the synergistic effect of linkage transmission mechanism, and adopts multiple reinforcement measures to ensure the stability of the column mold casting cavity.

[0012] When the mold is closed, the adjacent positive column concave mold, column side convex mold and negative column concave mold form the column mold casting cavity, and are reinforced by side support frame, pad plate and tensioning assembly.

[0013] Preferably, the limiting travel wheel has a conical structure.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this embodiment discloses a concrete power wall column casting linkage mold system, the detailed structure and operating principle of which are as follows. The system includes a first column mold base 2, at least two second column mold bases 7, at least one third column mold base 8, and a fourth column mold base 16. All column mold bases are arranged sequentially along the I-beam guide rail 3 and supported on the top surface of the upper horizontal part of the I-beam guide rail 3 by a traveling mechanism 4. The I-beam guide rail 3 serves as the guiding foundation for the entire system. The top surface of its upper horizontal part provides a stable support surface for the traveling mechanism 4, while the inner inclined surface is used to cooperate with the rolling of the limiting traveling wheel 15. The traveling mechanism 4 consists of a base frame plate and a roller assembly installed at its lower part. The roller assembly is installed on the lower part of the base frame plate through bearings to achieve smooth movement. At the same time, the base frame plate has sliding grooves on both sides, which are tightly fitted with the top surface of the upper horizontal part of the I-beam guide rail 3 to ensure the accuracy of the guiding function.

[0029] The base plates of two adjacent traveling mechanisms 4 are linked by a transmission connection mechanism, which includes a transmission connection plate 1 and a transmission connection column 6 fixed to the adjacent base plates. The transmission connection plate 1 has a slotted hole that fits onto the transmission connection column 6. This design allows the remaining mold bases to move synchronously when the first mold base 2 is driven to move along the I-beam guide rail 3, thereby completing the mold closing or opening operation. (See...) Figure 1 and Figure 4 As shown. The length of the strip hole in the transmission connecting plate 1 is set according to the maximum stroke of the column mold base to ensure that the transmission connecting mechanism can move flexibly within a predetermined range. The transmission connecting column 6 is fixed to the side wall of the base plate with bolts to ensure the stability of the connection.

[0030] The base plate of the traveling mechanism 4 of the first column mold base 2 and the fourth column mold base 16 is equipped with limiting traveling wheels 15, which adopt a conical structure. The limiting traveling wheels 15 are made of high-strength alloy steel and have a hardness of HRC58 or higher after quenching treatment, possessing excellent wear resistance and reliability. The design of the limiting traveling wheels 15 effectively prevents derailment during system operation, ensuring the operational stability of the mold system.

[0031] The first column mold base 2 is equipped with a forward column die 11, the second column mold base 7 is equipped with a column side punch 13, the third column mold base 8 is equipped with both a forward column die 11 and a backward column die 12, and the fourth column mold base 16 is equipped with a backward column die 12. During mold closing, starting from the first column mold base 2, each adjacent forward column die 11, two column side punches 13, and one backward column die 12 form a complete column mold casting cavity, as shown below. Figure 4As shown. The column casting cavity is used to place the reinforcing bars and pour concrete to complete the fabrication of the precast power wall column. Two column-side punches 13 on each second column casting base 7 participate in the formation of one column casting cavity, and each third column casting base 8 participates in the formation of two column casting cavities respectively through one forward column die 11 and one backward column die 12. The surfaces of the forward column die 11, the backward column die 12, and the column-side punches 13 are all provided with a polyurethane layer 17. The thickness of the polyurethane layer 17 is controlled between 1mm and 3mm, and it is attached to the mold surface by hot-melt bonding, providing good wear resistance and sealing performance. The polyurethane layer 17 not only extends the service life of the mold but also reduces the friction between the concrete and the mold surface during pouring, thereby improving the pouring quality.

[0032] To enhance the stability of the column mold casting cavity, the system employs a side support frame 10, a pad plate 14, and a tensioning assembly for multi-directional reinforcement. The side support frame 10 is bolted to the top of the forward column mold 11, and its pressing end is equipped with an arc-shaped pressure block. The radius of curvature of the arc-shaped pressure block matches the outer contour of the pad plate 14. After the mold is closed, the arc-shaped pressure block applies pre-tightening force through a hydraulic device, ensuring that the pad plate 14 fits tightly against the sides of the forward column mold 11 and the reverse column mold 12, preventing gaps or loosening during casting. The tensioning assembly includes a tie rod connecting plate 5 fixed to the first column mold base 2 and the fourth column mold base 16, and a tensioning rod (not shown in the figure) connecting the two tie rod connecting plates 5. The tensioning rod adopts a bidirectional threaded structure, with both ends engaging with the threaded holes of the tie rod connecting plate 5. By rotating the tensioning rod, the distance between the first column mold base 2 and the fourth column mold base 16 is adjusted, thereby achieving longitudinal tensioning of the column mold casting cavity. The tension rod has a pitch of 2mm to 4mm to ensure that the adjustment accuracy meets the construction requirements.

[0033] In practical applications, this concrete power wall column casting linkage mold system is suitable for various specifications of precast power wall columns. By adjusting the number and arrangement of the column mold bases, it can flexibly adapt to different casting requirements. For example, when making larger power wall columns, the number of second column mold bases 7 and third column mold bases 8 can be increased, and synchronous movement can be achieved through a transmission connection mechanism. When making smaller power wall columns, the number of column mold bases can be reduced to optimize construction efficiency. In addition, the modular design makes each column mold base easy to disassemble and assemble, facilitating transportation and storage.

[0034] The system operates as follows: First, the fourth column mold base 16 is fixed relative to the I-beam guide rail 3. Then, the first column mold base 2 is driven to move along the I-beam guide rail 3 via a drive mechanism. The movement of the first column mold base 2 drives the remaining column mold bases to move synchronously through a transmission connection mechanism, thereby realizing the mold closing operation. After the mold is closed, the column mold pouring cavity is reinforced multiple times by the side support frame 10, the pad plate 14, and the tensioning assembly to ensure that no deformation or loosening occurs during the pouring process. Subsequently, steel bars are placed in the column mold pouring cavity and concrete is poured. After the concrete solidifies, the drive mechanism is restarted to move the column mold bases relatively away, completing the mold opening operation and removing the prefabricated power wall column.

[0035] The technical solution of this embodiment achieves high precision, high stability, and high durability of the mold system through specific structural design and material selection. These characteristics enable the present invention to exhibit excellent performance in practical applications, meeting the demands of modern construction engineering for efficient and high-quality construction. For example, in a large-scale power project, the power wall columns produced using this system are dimensionally accurate and have smooth surfaces, significantly improving construction efficiency and reducing labor costs. Simultaneously, the presence of a polyurethane layer 17 on the mold surface reduces friction between the concrete and the mold, extending the mold's service life and further enhancing economic benefits.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
