Description
Technical Field
[0001] This utility model relates to the field of concrete pump pipe fixing technology, and in particular to a lightweight concrete pump pipe fixing device for high-rise buildings. Background Technology
[0002] During construction, securing concrete pump pipes is a crucial step in ensuring smooth progress. Traditional methods for securing pump pipes often involve welding embedded parts indoors or reinforcing them with steel pipe scaffolding. However, these methods have revealed numerous problems in long-term application.
[0003] In the construction of soundproof flooring and lightweight concrete in bathrooms, since the indoor concrete pump pipes have been removed and the pipe openings sealed after the initial construction, subsequent material transportation can only rely on wheelbarrows. This method is not only inefficient, but also causes changes in the chemical properties of the lightweight concrete due to the long transportation time, which seriously affects the construction quality.
[0004] In terms of fixing pump pipes on external walls, traditional techniques rely on temporary welding, which makes disassembling the pump pipes extremely difficult and can also damage the building's external wall structure, increasing the cost of later repairs and the difficulty of construction.
[0005] In addition, conventional clamp-type fixing devices lack pipe diameter adaptability adjustment function, cannot be adapted to pump pipes of different specifications, and do not have a shock absorption structure. The noise generated during construction will be transmitted into the room through the pump pipe, which not only affects the working environment of construction workers, but also easily disturbs the lives of surrounding residents.
[0006] In summary, existing pump pipe fixing technologies suffer from problems such as low construction efficiency, impact on construction quality, damage to building structures, and noise pollution. There is an urgent need to develop a new pump pipe fixing structure to overcome these technical defects. Utility Model Content
[0007] To address the shortcomings in the aforementioned background technology, this utility model proposes a lightweight concrete pump pipe fixing device for high-rise buildings. The technical problem to be solved is: how to improve the efficiency of concrete pouring construction, improve the construction quality, and avoid damage to the building structure.
[0008] The technical solution of this utility model is as follows:
[0009] A lightweight concrete pump pipe fixing device for high-rise buildings includes a connecting assembly that can be detachably connected to a reserved air conditioning opening in the main structure of the high-rise building. The connecting assembly is connected to a vibration damping assembly, which in turn is connected to a tie bolt assembly. The tie bolt assembly includes a left positioning plate positioned by a left positioning nut and a right positioning plate positioned by a right positioning nut. The left and right positioning plates are used to clamp the lightweight concrete pump pipe. This technical solution utilizes the connecting assembly to directly fix the lightweight concrete pump pipe to the reserved air conditioning opening, eliminating the need to damage the building's exterior wall structure or weld temporary supports, thus achieving efficient delivery of lightweight concrete while ensuring construction quality. Furthermore, the connection assembly, through the vibration damping assembly, effectively reduces vibration and noise pollution. Finally, the detachable connection between the connecting assembly and the reserved air conditioning opening, and the detachable connection between the tie bolt assembly and the lightweight concrete pump pipe, makes the entire fixing device standardized and modular, allowing for repeated disassembly and reuse over a long period, thereby reducing material waste.
[0010] Based on the above technical solutions, as a preferred technical solution for the fixing device of lightweight concrete pump pipes in high-rise buildings, the connecting component is a tie bolt assembly two. This technical solution provides a preferred structural form for the connecting component, also employing a tie bolt assembly, which, to distinguish it from tie bolt assembly one, is referred to as tie bolt assembly two. Using tie bolt assembly two not only facilitates assembly and disassembly but also has a very simple structure, including only tie rods, nuts, and corresponding positioning plates. When the dimensions of tie bolt assembly two are the same as those of tie bolt assembly one, the two can interchange parts, further improving the convenience of reuse.
[0011] Based on the above technical solution, as a preferred technical solution for the fixing device of lightweight concrete pump pipe in high-rise buildings, the tie bolt assembly 2 includes a left positioning plate 2 positioned by a left positioning nut 2 and a right positioning plate 2 positioned by a right positioning nut 2. The tie bolt 2 is used to pass through the reserved air conditioning opening, and the left positioning plate 2 and the right positioning plate 2 are used to clamp the walls on both sides of the reserved air conditioning opening.
[0012] Based on the above technical solutions, as a preferred technical solution for fixing lightweight concrete pump pipes in high-rise buildings, the vibration damping component is a disc spring. This technical solution provides a preferred implementation of the vibration damping component. The disc spring not only provides vibration damping but can also be directly welded to the structures on both sides, making assembly very convenient, durable, and with a long service life. It should be noted that in addition to disc springs, other types of vibration damping components can also be used. When cost is not a major concern, air springs, hydraulic springs, and other structural forms can be adopted.
[0013] Based on the above technical solutions, as a preferred technical solution for the fixing device of lightweight concrete pump pipes in high-rise buildings, the connecting assembly is welded to the disc spring through flange assembly one. This technical solution provides a preferred connecting structure for the disc spring, which can better transmit force through flange assembly one. Preferably, the connecting assembly adopts at least three tie rods two, and each tie rod is arranged in a circular array around the center of flange assembly one.
[0014] Based on the above technical solution, as a preferred technical solution for fixing lightweight concrete pump pipes in high-rise buildings, the disc spring and tie bolt assembly one are connected by a telescopic adjustment assembly. This technical solution adds a telescopic adjustment assembly, which can adjust the distance between tie bolt assembly one and the main structure of the high-rise building, thus making it suitable for various application scenarios. It should be noted that when the telescopic adjustment assembly is not used, the distance between the lightweight concrete pump pipe and the main structure of the high-rise building can also be adjusted by adjusting tie bolt assembly one and tie bolt assembly two. When it is necessary to reduce the distance, the nut of tie bolt assembly one can be adjusted to the right, or the nut of tie bolt assembly two can be adjusted to the left; when it is necessary to increase the distance, the nut of tie bolt assembly one can be adjusted to the left, or the nut of tie bolt assembly two can be adjusted to the right.
[0015] Based on the above technical solutions, as a preferred technical solution for the fixing device of lightweight concrete pump pipe in high-rise buildings, the telescopic adjustment assembly includes a flange assembly two, which includes a flange plate two welded to a butterfly spring, a stud is set through the flange plate two, the stud is positioned by locking nuts on both sides of the flange plate, and the end of the stud is provided with an internal thread cavity that is threadedly connected to the tie bolt one of the tie bolt assembly one.
[0016] Based on the above technical solutions, as a preferred technical solution for fixing lightweight concrete pump pipes in high-rise buildings, a locking nut for locking the end of the internal thread cavity is provided on the tie bolt.
[0017] Based on the above technical solutions, as a preferred technical solution for fixing lightweight concrete pump pipes in high-rise buildings, the tie bolt assembly includes at least four parallel tie bolts, and the connecting assembly includes at least four tie rods.
[0018] Based on the above technical solutions, as a preferred technical solution for fixing lightweight concrete pump pipes in high-rise buildings, the inner sides of both the left and right positioning plates are provided with rubber pads for fitting the lightweight concrete pump pipes.
[0019] This utility model proposes a lightweight concrete pump pipe fixing device for high-rise buildings, which has the following advantages compared with the prior art:
[0020] Adaptive fixing system: Through the combination of combined supports, clamps and butterfly springs, it can adapt to different external wall thicknesses and different pump pipe spacing requirements, solving the problem of traditional single support.
[0021] Integrated vibration damping and noise reduction design: The rubber damping layer and the butterfly spring work together to reduce vibration transmission efficiency by more than 40%, meeting the requirements of the "Code for Sound Insulation Design of Civil Buildings" GB50118-2010.
[0022] Full-cycle reusable technology: The pre-embedded sleeve and quick-release connector form a closed-loop reusable system, saving 1.2 tons of steel per 10,000 square meters per project and reducing carbon emissions by 18 kg per cycle.
[0023] This technical solution adopts a modular design, which solves three major industry problems: traditional pump pipe fixing devices are not reusable, damage the building structure, and affect subsequent construction. It is particularly suitable for high-rise building renovation projects that require multiple pump pipe disassemblies and reassemblies. Attached Figure Description
