Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a novel pre-embedded structure for segment channels. Background Technology

[0002] Pre-embedded channels can be used in subways, high-speed railways, buildings, and other applications. Pre-embedded channels are components that are pre-installed (buried) within the project. They are components placed during the pouring of concrete to facilitate the installation and fixation of external engineering equipment foundations. Therefore, pre-embedded channels need to be prefabricated in the tunnel lining segments, which requires fixing the pre-embedded channels to the segment mold.

[0003] Limitations of grooving technology: While pre-embedded grooving technology improves construction efficiency to some extent, it still has shortcomings in terms of groove fixation and sealing. This can lead to difficulties in ensuring the sealing performance between the groove and the tunnel lining segments, resulting in grout leakage and potential blockage of the groove opening. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a new type of pre-embedded structure for segment channels to solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is: a novel pre-embedded structure for tunnel segments, comprising a template body, with opposing support frames on both sides of the template body's end face. The support frames have a convex cross-section, and their bottoms match the openings of the tunnel's end face. The opening of the tunnel is aligned with the support frame and inserted. Then, blocking plates are installed at both ends of the tunnel. The end face of the blocking plate has connecting protrusions that match the two ends of the tunnel's opening, allowing it to be inserted into the tunnel opening for connection. The end face of the blocking plate has first sliding grooves on both sides, and the two ends of the support frame have connecting plates that match the first sliding grooves.

[0007] In some embodiments, the support frame has a plurality of hollow tubes on the side opposite to the template body. The hollow tubes are fixed in the template body and one end protrudes from the outer end face of the template body. A matching sliding rod is provided inside the hollow tube. One end of the sliding rod protrudes from the hollow tube and is fitted with a threaded cap. The threaded cap is threadedly connected to the hollow tube. A protruding ring is provided on the outer wall of the threaded cap. A spring is provided between the protruding ring and the template body. The support frame has second sliding grooves on both sides that are embedded in the channel. A locking block is provided in the second sliding groove. A connecting rod is provided at one end of the locking block. The support frame has a slot communicating with the hollow tube so that the other end of the sliding rod can be inserted into it. The connecting rod is connected to the sliding rod.

[0008] In some embodiments, the outer wall of the threaded cap is provided with anti-slip grooves.

[0009] In some embodiments, the end face of the template body is provided with a plurality of threaded holes that match the hollow tube, the end of the hollow tube is rotatably disposed with the support frame, and the surface of the hollow tube is provided with threads that match the threaded holes.

[0010] In some embodiments, the threaded cap end face is connected to the sliding rod by a screw.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are:

[0012] Place the connecting plate on both sides of the channel, then align the opening of the channel with the support frame and insert it. Because the support frame is convex, the top can be submerged in the channel, and the bottom can cover the entire opening for sealing. This prevents mud from flowing into the opening during pre-embedding, thus making it unusable.

[0013] By replacing the support frame, production costs can be saved without replacing the entire template body, and the support frame can be replaced with a matching one according to the corresponding length.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0015] Undoubtedly, such and other objects of this invention will become more apparent after the following detailed description of the preferred embodiments, which are illustrated in various accompanying drawings and illustrations.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] Reference Figure 1-7This utility model provides a novel pre-embedded structure for tunnel segment channels, including a template body 1. The template body 1 has opposing support frames 2 on both sides of its end face. The support frame 2 has a convex cross-section and its bottom matches the opening of the end face of the channel 3. The channel opening of the channel 3 is aligned with the support frame 2 and inserted. Then, blocking plates 4 are installed at both ends of the channel 3. The end face of the blocking plate 4 has connecting protrusions 41 that match the two ends of the channel opening of the channel 3, allowing it to be inserted into the channel opening for connection. The end face of the blocking plate 4 has a first sliding groove 42 on both sides. The support frame 2 has connecting plates 21 that match the first sliding groove 42 at both ends.

[0033] First, attach the connecting plate 21 to both sides of the channel 3. Then, align the opening of the channel 3 with the support frame 2 and insert it. Because the support frame 2 is convex, its top can be submerged in the channel 3, and its bottom can cover the entire opening for sealing. This prevents slurry from flowing into the opening during pre-embedding, thus rendering the channel unusable. After placing the formwork body 1, insert the reinforcing steel frame into the formwork body 1, and then pour in cement slurry to solidify and form a segment. Once formed, the channel 3 and support frame 2 will separate when the segment is lifted in the forward direction, completing the pre-embedding of the channel 3. Additionally, apply adhesive between the blocking plate 4 and the channel 3 to ensure a good connection, preventing the blocking plate 4 from separating when cement slurry is poured in.

[0034] According to some embodiments of this utility model, optionally, the support frame 2 is provided with a plurality of hollow tubes 22 on the side opposite to the template body 1. The hollow tubes 22 are fixed in the template body 1, and one end protrudes from the outer end face of the template body 1. A matching sliding rod 23 is provided inside the hollow tube 22. One end of the sliding rod 23 protrudes from the hollow tube 22 and is fitted with a threaded cap 24. The threaded cap 24 is threadedly connected to the hollow tube 22. A protruding ring 25 is provided on the outer wall of the threaded cap 24. A spring 26 is provided between the protruding ring 25 and the template body 1. The support frame 2 is provided with second sliding grooves 27 on both sides that are embedded in the groove 3. A locking block 28 is provided in the second sliding groove 27. A connecting rod 29 is provided at one end of the locking block 28. The support frame 2 is provided with a groove that communicates with the hollow tube 22, allowing the other end of the sliding rod 23 to be inserted therein. The connecting rod 29 is connected to the sliding rod 23.

[0035] By partially embedding the support frame 2 into the channel 3, the sliding rod 23 slides up and down, driving the connecting rod 29 to pull the locking block 28 back and forth in the second sliding groove 27. This allows the locking block 28 to be locked in the channel 3. By rotating the threaded cover 24, it is separated from the hollow tube 22. When the spring 26 returns to its original position, it pushes up the sliding rod 23, which then pushes out the locking block 28, locking it in the channel 3 to ensure its connection and prevent the channel 3 from falling. At the same time, the template body 1 is generally erected and placed flat for easy operation and to prevent the spring 26 from being compressed back. After the tube segment is made, the spring 26 needs to be compressed in advance before connecting the threaded cover 24 and the hollow tube 22, allowing the locking block 28 to retract for subsequent separation.

[0036] According to some embodiments of this utility model, optionally, the outer wall of the threaded cap 24 is provided with anti-slip grooves. This facilitates smooth rotation of the threaded cap 24 and provides a relative anti-slip effect.

[0037] According to some embodiments of this utility model, optionally, the end face of the template body 1 is provided with a plurality of threaded holes 5 that match the hollow tube 22. The end of the hollow tube 22 is rotatably disposed with the support frame 2, and the surface of the hollow tube 22 is provided with threads that match the threaded holes 5. In this way, if the support frame 2 is damaged after long-term use, the hollow tube can be separated from the template body 1 and the corresponding support frame 2 can be replaced.

[0038] According to some embodiments of this utility model, optionally, the end face of the threaded cover 24 is connected to the sliding rod 23 by screws. This facilitates the disassembly and removal of the support frame 2.

[0039] Working principle:

[0040] First, attach the connecting plate 21 to both sides of the channel 3. Then, align the opening of the channel 3 with the support frame 2 and insert it. Because the support frame 2 is convex, its top can be submerged in the channel 3, and its bottom can cover the entire opening for sealing. This prevents mud from flowing into the opening during pre-embedding, thus rendering it unusable. Then, by partially submerging the support frame 2 in the channel 3, the sliding rod 23 slides up and down, driving the connecting rod 29 to pull the locking block 28 back and forth in the second sliding groove 27. This allows the locking block 28 to be locked in the channel 3. Rotate the threaded cap 24 to separate it from the hollow tube 22. In this way, when the spring 26 returns to its original position, it will push up the sliding rod 23, which will then push out the locking block 28 and lock it onto the channel 3 to ensure its connection. At the same time, the template body 1 is generally erected and placed flat, which facilitates operation and prevents the spring 26 from being compressed back. After the template body 1 is placed, the steel reinforcement frame is placed into the template body 1, and then cement slurry is poured in to solidify and form the pipe segment. After it is formed, the spring 26 needs to be compressed in advance, and then the threaded cap 24 and the hollow tube 22 are connected to retract the locking block 28. When the pipe segment is lifted in the forward direction, the channel 3 and the support frame 2 are separated, completing the pre-embedding of the channel 3.
