Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a precise positioning device for the inner sleeve of a circumferential core-pulling beam. Background Technology

[0002] In today's construction and many related engineering fields, the installation of galvanized steel pipe 1 is a crucial and frequently performed task. With the continuous expansion of the scale of various engineering projects, the increasing technical requirements, and the increasingly stringent construction quality standards, the accuracy of the installation position of galvanized steel pipe 1 has become a key factor affecting the overall project quality and the smooth progress of subsequent procedures. In the installation of galvanized steel pipe 1, the installation and positioning of galvanized steel pipe 1 pre-embedded in beams is very troublesome. The traditional method of positioning galvanized steel pipe 1 is to first position it, and then use short steel bars to spot weld it to the galvanized steel pipe 1 and the steel reinforcement cage around it for reinforcement. In practical applications, many problems have gradually been exposed. This fixing method is time-consuming and wasteful of costs. Moreover, during the pouring process, the steel reinforcement cage is bound to shift or the galvanized steel pipe 1 may be displaced due to the influence of concrete vibration. In addition, since the beam size is often only 200mm to 300mm, and it is filled with steel bars, the space is extremely narrow, making installation very difficult. Therefore, the positioning accuracy of this method cannot meet the requirements of complex projects, the operation process is cumbersome, the construction efficiency is low, and the one-time use causes resource waste and increased costs.

[0003] We considered developing a fixing device for galvanized steel pipes 1 within concrete. This device must ensure accurate pre-embedded positioning, be easy to operate, and save time and labor. The "Precise Positioning Device for Galvanized Steel Pipes 1 in a Reusable Core-Pulling Beam" was developed to address this need. Its emergence is not only an improvement and innovation of traditional positioning methods but also a response to the urgent demands of modern engineering construction for efficient, precise, and economical construction. This device aims to achieve high-precision positioning control of the galvanized steel pipe 1 through advanced design concepts and structural composition, while also possessing reusable characteristics to reduce construction costs and improve resource utilization. This innovative achievement has significant practical implications for promoting technological progress in the construction and related industries, improving the quality and efficiency of engineering construction, and is expected to play a significant role in a wide range of engineering applications, providing strong support for the smooth implementation of various engineering projects.

[0004] In order to solve the problems existing in the prior art, the present invention provides a device for precise positioning of the inner sleeve of a circumferential core-pulling beam.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A precise positioning device for the inner sleeve of a circumferential core-pulling beam is characterized by comprising a galvanized steel pipe 1 and a positioning disc 5; wherein: a telescopic spring 2 is installed inside the galvanized steel pipe 1, and the telescopic spring 2 can freely expand and contract within the galvanized steel pipe 1, thereby allowing it to be easily inserted into the galvanized steel pipe 1; a circular washer 3 is welded and fixed to the outer end of the telescopic spring 2, and the washer 3 is confined within the galvanized steel pipe 1 by the end of the galvanized steel pipe 1; a core head 4 is welded to the outside of the washer 3; the positioning disc 5 is a circular steel plate, and a core head hole 6 with an outer diameter adapted to the core head 4 is provided at the center of the positioning disc 5.

[0007] This utility model also has the following additional technical features:

[0008] As a further specific optimization of the technical solution of this utility model: the galvanized steel pipe 1 is a galvanized steel pipe with a length of 270mm and an inner diameter of DN25mm; the telescopic spring 2 is a telescopic spring with a length of 280mm; the gasket 3 is a steel plate with a thickness of 3mm; the core head 4 is a steel bar with a length of 40mm and a diameter of Φ8mm; and the thickness of the positioning disc 5 is set to 5mm.

[0014] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0015] A precise positioning device for the inner sleeve of a rotating core-pulling beam includes a galvanized steel pipe 1 and a positioning disc 5.

[0016] A telescopic spring 2 is installed inside the galvanized steel pipe 1. The telescopic spring 2 can freely extend and retract inside the galvanized steel pipe 1, so it can be easily inserted into the galvanized steel pipe 1. A circular washer 3 is welded and fixed to the outer end of the telescopic spring 2. The washer 3 is confined in the galvanized steel pipe 1 by the end of the galvanized steel pipe 1. A core 4 is welded to the outside of the washer 3.

[0017] The galvanized steel pipe 1 serves as a foundation for the installation and support of other components, ensuring the entire device maintains a stable shape during use without deformation or displacement, thus guaranteeing accurate positioning. Because the galvanized steel pipe 1 contains an internal telescopic spring 2, it can freely expand and contract within the pipe, allowing for easy insertion. The device then firmly secures the galvanized steel pipe 1 onto the positioning disc 5, enabling precise and quick installation and removal of the pipe.

[0018] The positioning disc 5 is a circular steel plate, and a core hole 6 with an outer diameter of the core 4 is provided at the center of the positioning disc 5.

[0019] The galvanized steel pipe 1 is a galvanized steel pipe with a length of 270mm and an inner diameter of DN25mm; the telescopic spring 2 is a telescopic spring with a length of 280mm; the gasket 3 is a steel plate with a thickness of 3mm; the core head 4 is a steel bar with a length of 40mm and a diameter of Φ8mm; and the thickness of the positioning disc 5 is set to 5mm. The selection of the above materials can ensure sufficient strength and stability of the precise positioning device.

[0020] The diameter of the core hole 6 is slightly larger than the diameter of the core 4, so that the core 4 can be smoothly inserted into the core hole 6, but the positioning accuracy will not be affected by the excessive gap, thus ensuring the stability of the entire positioning device during use.

[0021] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
