Description

Technical Field

[0001] This utility model relates to the technical field of secondary structure construction and steel platform technology for airport baggage systems, and particularly to the embedded structure of airport baggage systems. Background Technology

[0002] Airport baggage system embedded components refer to the components that are pre-embedded in the ground or walls during airport construction to support and fix the baggage system. These embedded components typically include brackets, guide rails, fixing bolts, etc. They are installed in the designed locations at the beginning of airport construction so that various equipment can be quickly and accurately connected and fixed during the subsequent baggage system installation process.

[0003] Currently, most of the embedded parts used domestically and internationally involve welding and fixing the reinforcing bars to the embedded plates and embedding them into the concrete. During structural or secondary structural construction, the purpose is to connect the secondary structure by welding with the embedded parts. However, because welding is carried out on a large area with the embedded plates during secondary structural construction, it can damage the original concrete structure. On-site welding can also easily cause fires. In many cases, the quality of on-site welding is unreliable, resulting in the on-site welded parts falling off. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as damage to the original concrete structure caused by on-site welding and unreliable on-site welding quality, and to propose an embedded component structure for airport baggage systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Airport baggage system embedded structure, including:

[0007] The embedded steel plate 1 and the conversion steel plate are provided. The bottom of the embedded steel plate 1 is rectangular and fixedly provided with multiple embedded steel bars. The bottom of the embedded steel bars is fixedly provided with the same embedded steel plate 2.

[0008] The connecting bolts are provided corresponding to the pre-embedded reinforcing bars, and both ends of the connecting bolts are provided with external threads.

[0009] In one possible design, the bottom ends of the pre-embedded reinforcing bars all pass through the second pre-embedded steel plate, and the end of the pre-embedded reinforcing bars that passes through the second pre-embedded steel plate is provided with internal threads. The upper end of the connecting bolt is adapted to the internal threads of the pre-embedded reinforcing bars through external threads and can be disconnected from the threaded connection.

[0010] In one possible design, the bottom of the conversion steel plate has a rectangular through hole, and the bottom of the connecting bolts are respectively inserted into the through hole at the bottom of the conversion steel plate. The bottom of the conversion steel plate is fixedly mounted to the hanging column at the center.

[0011] In one possible design, anti-slip pads are fitted around the external threads at the upper end of the connecting bolts.

[0012] In one possible design, both the outer surface of the upper external thread and the lower external thread of the connecting bolt are threaded with nuts.

[0013] In one possible design, a concrete structural slab is poured outside the first embedded steel plate, the second embedded steel bar, and the third embedded steel plate. The bottom of the concrete structural slab has reserved holes, and the reserved holes correspond to the positions of the second embedded steel bar through which the steel bar passes.

[0014] In this application, before concrete pouring, the embedded parts are precisely positioned and installed. The first embedded steel plate serves as the main positioning base, and its bottom is fixed with embedded steel bars by welding or mechanical connection. The bottom of these embedded steel bars is then uniformly fixed to the second embedded steel plate to form a stable assembly. Subsequently, the assembly of the first embedded steel plate, the embedded steel bars, and the second embedded steel plate is placed in the predetermined position, and the surrounding area is poured into a concrete structural slab. During the pouring process, reserved holes are specially opened at the bottom of the concrete structural slab to ensure that the embedded steel bars can pass through smoothly and remain in the predetermined position without being completely encased by concrete. After the bottom of each embedded steel bar passes through the second embedded steel plate, its end is processed with internal threads. These internal threads match the external threads of the connecting bolts used in subsequent installation, realizing a detachable threaded connection. The setting of connecting bolts not only enhances the strength of the connection but also provides convenient disassembly and assembly capabilities, facilitating subsequent maintenance and adjustment.

[0015] Once the concrete slab reaches its design strength, the installation of the baggage system steel platform begins. At this stage, the connecting bolts are threaded together with the internal threads of the embedded reinforcing bars via their external threads. These are then tightened with nuts. A conversion steel plate is introduced as a connector, with through holes at its bottom corresponding to the connecting bolts, allowing the conversion steel plate to be accurately installed onto the embedded parts. A hanging column is fixed at the center of the conversion steel plate, supporting the entire baggage system steel platform. In this way, all loads on the steel platform are ultimately transferred to the embedded structure via the hanging column, conversion steel plate, and connecting bolts, achieving stable support.

[0016] To ensure the stability and safety of the connection, additional anti-slip and tightening measures are taken for the external threads at both ends of each connecting bolt. An anti-slip washer is fitted on the outside of the upper external thread to increase friction and prevent loosening. At the same time, nuts are threaded to the external threads at both ends. One nut at the upper end is used for initial tightening, while the two nuts at the lower end provide additional tightening force and stability.

[0017] This utility model has the following beneficial effects:

[0018] This utility model replaces the traditional embedded parts and on-site welding methods in secondary structures and airport baggage systems by using a combination of pre-embedded steel plates, pre-embedded reinforcing bars, connecting bolts and conversion steel plates. This effectively avoids the fire risk caused by welding operations, while achieving a safe and reliable connection with the embedded parts. The connecting components can be easily disassembled when necessary, significantly reducing the damage to the original concrete structure caused by the high temperature of welding. In addition, it greatly reduces the material usage cost and subsequent construction cost, bringing a more economical and efficient construction solution to the project.

[0019] This utility model adopts a combination of pre-embedded steel plates, reinforcing bars, connecting bolts and conversion steel plates, which innovates the installation process of secondary structures and airport baggage systems, effectively preventing welding disasters, ensuring safety, facilitating disassembly, reducing losses and lowering costs, and achieving economical and efficient construction.

The bottom of these pre-embedded steel bars 3 are all fixedly connected to the same pre-embedded steel plate 201 in order to enhance the overall stability and load-bearing capacity of the pre-embedded parts.

[0029] In addition, six connecting bolts 4 are provided, each of which has external threads 401 at both ends. These connecting bolts 4 will serve as key components for connecting the embedded steel plate and the conversion steel plate 5.

[0030] During the specific installation, the pre-embedded steel plate 1, 2, six pre-embedded steel bars 3 and pre-embedded steel plate 201 are first assembled and poured into the concrete structural slab 1. Six reserved holes are pre-drilled at the bottom of the concrete structural slab 1. The positions of these reserved holes correspond to the ends of the pre-embedded steel bars 3 that pass through the pre-embedded steel plate 201, so as to ensure that the pre-embedded steel bars 3 can be smoothly exposed and facilitate the subsequent installation and connection of the connecting bolts 4.

[0031] Subsequently, the upper end of the connecting bolt 4 is threaded to the inner thread 301 at the bottom of the pre-embedded steel bar 3 through the external thread 401, so as to achieve a stable connection between the connecting bolt 4 and the pre-embedded part. In order to increase the reliability of the connection and the anti-slip performance, an anti-slip pad 8 is also fitted on the outside of the upper external thread 401 of each connecting bolt 4.
