Description

Technical Field

[0001] The utility model relates to the technical field of concrete casting formwork, in particular to a pedestal module suitable for concrete casting of curved surface structures. Background Art

[0002] In modern construction projects, the construction of continuous irregular curved surface concrete structures has always been a technical challenge. Traditional construction methods (such as CN 203213585 U) rely on the splicing of a large number of wooden strips to form a so-called "quasi-curved surface matrix", which is not only time-consuming and laborious, but also difficult to control the accuracy. Specifically, the splicing of wooden strips usually highly depends on the manual operation of workers. This manual-dependent method is difficult to ensure the precise splicing of each wooden strip, resulting in deviations between the finally formed curved surface mold and the design drawing. Such deviations are particularly obvious in the construction of continuous irregular curved surfaces because it requires extremely high shape consistency and accuracy.

[0003] In addition, for irregular curved surface structures that require continuous casting, traditional methods require the manufacture of a large number of "quasi-curved surface matrices", which is not only inefficient but also greatly prolongs the construction period. In modern construction projects, a long construction period not only increases the cost of the project but also may affect the progress and quality of the entire project.

[0004] Finally, the wooden strips used in traditional methods are usually disposable, which means that a large amount of wood resources are required after each construction, and these wooden strips are often not reusable after construction, resulting in economic waste.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these deficiencies, and the present utility model is made based on this situation. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a pedestal module suitable for concrete casting of curved surface structures with high efficiency and high precision.

[0007] The utility model is realized by the following technical solutions:

[0008] To solve the above technical problems, the utility model provides a pedestal module suitable for concrete casting of curved surface structures, including a base, and a plurality of pedestal units are arranged on the base. Each pedestal unit includes a telescopic push rod and a driving element for driving the telescopic movement of the push rod. The end of the output end of each push rod is provided with a suction cup, and a universal connection structure for universally connecting the two is arranged between the suction cup and the corresponding push rod;

[0009] The ends of the output ends of the push rods have different extended lengths, so that the suction cups form a fluctuating curved surface dot matrix, and a flexible curved film is attached and installed on the curved surface dot matrix.

[0010] In order to further solve the technical problems to be solved by the present invention, in a seat module applicable to the casting of concrete with a curved surface structure provided by the present invention, the driving element is a stepping motor or a servo motor, and a transmission structure is provided between the driving element and the push rod.

[0011] In order to further solve the technical problems to be solved by the present invention, in a seat module applicable to the casting of concrete with a curved surface structure provided by the present invention, the transmission structure is a ball screw pair or a gear rack pair.

[0012] In order to further solve the technical problems to be solved by the present invention, in a seat module applicable to the casting of concrete with a curved surface structure provided by the present invention, the universal connection structure is a ball hinge structure.

[0013] In order to further solve the technical problems to be solved by the present invention, in a seat module applicable to the casting of concrete with a curved surface structure provided by the present invention, the ball hinge structure includes a ball bowl provided at the end of the output end of the push rod and a ball head provided on the suction cup and capable of cooperating with the ball bowl.

[0017] In order to further solve the technical problems to be solved by the present invention, in a seat module applicable to the casting of concrete with a curved surface structure provided by the present invention, a control system is further included, and each driving element is electrically connected to the control system.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The entire placenta module of the present utility model can achieve efficient automatic control, ensuring the precise synchronous operation of each push rod during the concrete pouring process. Since the placenta module in this embodiment relies on digital drive to complete, and the curved surface data coordinate set is directly obtained from the design drawings, the curved surface carcass composed of a large number of placenta units can highly coincide with the design drawings, significantly improving the accuracy of the mold. In addition, the process of building the curved surface placenta completed by automatic control is extremely fast, which can significantly improve the construction efficiency and shorten the construction period.

[0020] 2. In the present utility model, a suction cup is provided at the output end of each said push rod.

[0022] 4. The placenta unit (including the drive push rod and the drive element) in the present utility model also has the characteristic of being reusable. Compared with the traditional method of building the mold placenta. This reusable characteristic reduces material waste, lowers costs, and is more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further details the specific embodiments of the present utility model in conjunction with the drawings, where:

[0024] Figure 1 is a schematic structural diagram of the present utility model;

[0025] Figure 2 is a schematic structural diagram of the placenta unit. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] As Figures 1 to 2 shown, a placenta module is designed specifically for the concrete pouring of non-regular curved surface structures, aiming to solve the various deficiencies of the traditional wooden strip splicing method. The core components of this placenta module include a base (not shown in the figure), and a plurality of placenta units 1 are installed on the base. Each placenta unit 1 is equipped with a telescopic push rod 11, and these push rods are controlled by efficient drive elements 12 for their telescopic movements.

[0028] Specifically, the driving element 12 is a stepper motor or a servo motor, which can provide precise position control and stable power output. A transmission structure is designed between the driving element 12 and the push rod 11. The transmission structure can be a ball screw pair or a rack and pinion pair, both of which can effectively convert the rotational motion of the motor into the linear motion of the push rod, ensuring that the telescopic action of the push rod is both stable and precise.

[0029] A suction cup 13 is provided at the output end of each push rod 11, and a universal connection structure 14 for connecting the two in all directions is provided between the suction cup 13 and the corresponding push rod 11. This design enables the suction cup 13 to flexibly adjust its angle and position, thereby improving the adaptability and precision of the entire system.

[0030] Preferably, the universal connection structure 14 is a ball joint structure. More specifically, the ball joint structure includes a ball bowl provided at the output end of the push rod 11, and a ball head provided on the suction cup 13 and capable of cooperating with the ball bowl. This design ensures that the suction cup 13 can freely rotate in multiple directions, thus better adapting to various shapes and positions of the curved membrane sheet 2.

[0031] Due to the different extended lengths of the output ends of the push rods 11, the suction cups 13 together form a fluctuating curved surface lattice. This curved surface lattice is adapted to the irregular curved surface building structure where concrete needs to be poured, ensuring that the finally formed concrete structure can accurately reflect the requirements of the design drawings. On this curved surface lattice, a flexible curved membrane sheet 2 is fitted. The function of the curved membrane sheet 2 is to form a smooth overall curved surface on the curved surface lattice to prevent slurry leakage during the concrete pouring process.

[0032] This curved membrane sheet is preferably made of a rubber gasket. Rubber has good elasticity and adaptability and can closely fit the curved surface formed by the output end of the push rod 11. This close fit ensures the accurate shape during concrete pouring and avoids common defects and errors in traditional methods.

[0033] The suction cup 13 can not only hold the curved membrane sheet 2, playing a role of temporary fixation to avoid problems such as warping or improper fitting during the installation of the curved membrane sheet 2. At the same time, the universal connection structure 14 also enables the suction cup 13 to freely rotate in multiple directions, so that the suction cup 13 can adaptively fit the curved membrane sheet 2. Such a design further enhances the flexibility and accuracy of the entire system, enabling the curved membrane sheet 2 to more firmly cover the curved surface lattice and ensuring the smooth progress of the concrete pouring process.

[0034] More specifically, each of the push rods 11 is arranged in parallel. This parallel arrangement design not only ensures the stability of the entire module in terms of structure, but also provides a high degree of controllability and consistency during operation. The parallel arrangement of each push rod 11 enables the drive system (here, the drive system refers to the drive element 12 and the control system 3 described later) to synchronously adjust the lengths of the extensions of each push rod, thereby forming a continuous and smooth curved surface lattice. This arrangement greatly reduces the mutual interference between the push rods 11, ensuring the accuracy and uniformity of the curved surface lattice. In addition, the parallel push rods 11 can also simplify the design and operation of the drive system, making the entire module more efficient and reliable in use.

[0035] More specifically, the push rod 11 is a steel rod. The steel rod has excellent mechanical properties, including high strength, high hardness, and good wear resistance, and can maintain stable performance in complex construction environments. Using a steel rod not only extends the service life of the module, but also improves its load-bearing capacity and stability. The push rod made of steel can withstand large mechanical stresses and impact forces, ensuring that the push rod is not easily bent or deformed during the concrete pouring process, thereby guaranteeing the accuracy and stability of the finally formed concrete curved surface structure.

[0036] To achieve digital control, the mold base module of the present utility model further includes a control system 3, and each drive element 12 is electrically connected to the control system 3. Through this control system, the entire mold base module can achieve efficient automatic control, ensuring the precise synchronous operation of each push rod 11 during the concrete pouring process.

[0037] When pouring concrete for an irregular curved surface structure, first, it is necessary to obtain the lattice data with a certain spacing of the curved surface structure to obtain the curved surface data coordinate set. Each coordinate in the coordinate set corresponds to the position of a set of mold base units 1. The control system 3 controls the push rods 11 of each mold base unit 1 to extend and retract to the corresponding distances according to these coordinate data. When all the mold base units 1 are adjusted to the corresponding positions, the suction cups 13 at the outer ends of the push rods 11 form a complete curved surface lattice. Next, a flexible curved surface film 2 is covered on this curved surface lattice to complete the formation of the curved surface mold base.

[0038] When it is necessary to build the mold bases of different structural parts, only the corresponding curved surface data coordinate set needs to be input into the control system 3. The control system will automatically calculate and give the extension and retraction instructions for each mold base unit 1 according to these coordinate data, so as to quickly and accurately build the required curved surface mold base.

[0039] Since the placenta module in this embodiment relies on digital drive to complete, and the curved surface data coordinate set is directly obtained from the design drawings, the curved surface placenta composed of a large number of placenta units 1 can highly match the design drawings, significantly improving the accuracy of the mold. In addition, the process of building the curved surface placenta completed by automatic control is extremely fast, which can significantly improve the construction efficiency and shorten the construction period.

[0040] The placenta unit 1 (including the drive push rod 11 and the drive element 12) in this embodiment also has the characteristic of being reusable. Compared with the traditional way of building the mold placenta, this solution not only improves the economy but also is more environmentally friendly. This reusable characteristic reduces material waste and lowers costs. Through this innovative design of the placenta module, the utility model can achieve higher accuracy, faster speed and lower costs during the construction process, while making a positive contribution to environmental protection.
