Description

Technical Field

[0001] This utility model relates to the field of pre-embedded channels, specifically a pre-embedded railway channel. Background Technology

[0002] An embedded channel is a load-bearing anchoring component used for cast-in-place and precast concrete components. Currently, the embedded channels used in high-speed rail, subway, and integrated pipe gallery fields are all embedded in the concrete after the channel is welded or riveted to the anchor rod.

[0003] Because the existing embedded channels are rigidly connected to the concrete and cast as one piece, their position is permanently fixed after casting and cannot be disassembled or moved according to subsequent design changes, making it inconvenient to use them again. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pre-embedded railway channel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An embedded railway channel includes a channel body, the channel body including two oppositely arranged mounting frames, a fixing plate detachably provided between the two mounting frames, a plurality of anchor rods detachably provided on the fixing plate, a first limiting plate located outside the fixing plate on the anchor rod, a second limiting plate located between the two mounting frames on the anchor rod on one side of the first limiting plate, and a fastening plate on the anchor rod between the second limiting plate and the first limiting plate.

[0007] As a further embodiment of this utility model, the fixing plate is provided with a plurality of first locking holes for inserting locking bolts, and the mounting bracket is provided with a second locking hole that communicates with the first locking holes.

[0008] As a further embodiment of this utility model, the fixing plate is provided with a plurality of guide grooves for the second limiting plate to pass through, and the fixing plate on one side of the guide groove is provided with a travel groove for the anchor rod to move.

[0009] As a further embodiment of this utility model, the mounting frame is provided with a second limiting plate that passes through the guide groove and cooperates with the fastening plate after the anchor rod is displaced.

[0010] As a further embodiment of this utility model, the anchor rod is provided with a series of interlocking rods evenly distributed around the axis, and the interlocking rods are arranged in a staggered manner.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Both the channel body and the fixing plate of this utility model are detachable and reusable, which meets the modern building's pursuit of flexibility and sustainable development, and has broad application prospects in the fields of high-speed rail, subway, and integrated pipe gallery.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Example

[0023] refer to Figures 1-6An embedded railway channel includes a channel body 1, which includes two oppositely arranged mounting frames 11. A fixing plate 2 is detachably provided between the two mounting frames 11. A plurality of anchor rods 3 are detachably provided on the fixing plate 2. A first limiting plate 31 located outside the fixing plate 2 is fixedly connected to the anchor rod 3. A second limiting plate 32 located between the two mounting frames 11 is fixedly connected to the anchor rod 3 on one side of the first limiting plate 31. A fastening plate 33 is fixedly connected to the anchor rod 3 between the second limiting plate 32 and the first limiting plate 31.

[0024] The fixing plate 2 has multiple first locking holes 21 through which locking bolts 4 are inserted, and the mounting bracket 11 has a second locking hole 12 through which it communicates with the first locking holes 21.

[0025] The fixing plate 2 has multiple guide grooves 22 through which the second limiting plate 32 passes. The fixing plate 2 on one side of the guide groove 22 has a travel groove 23 for the anchor rod 3 to move. The travel groove 23 is connected to the guide groove 22.

[0026] The mounting bracket 11 has a second limiting plate 32 that passes through the guide groove 22 and engages with the fastening plate 33 after the anchor rod 3 is displaced. Through the engagement of the two fastening half grooves 13 with the fastening plate 33, the installation positions of the two mounting brackets 11 can be accurately positioned to ensure the installation stability of the channel body 1 and the anchor rod 3.

[0027] The anchor rod 3 is provided with interlocking rods 34 evenly distributed around the axis, and the interlocking rods 34 are arranged in a staggered manner. The interlocking rods 34 enhance the gripping force and pull-out resistance between the anchor rod 3 and the concrete. The staggered interlocking rods 34 form a stable three-dimensional anchoring system inside the concrete, effectively preventing the anchor rod 3 from being easily pulled out and ensuring the load-bearing safety of the entire node.

[0028] The working principle of this utility model:

[0029] First, the end of the anchor rod 3 with the interlocking rod 34 is pre-embedded in the concrete. During the pre-embedding process, it is necessary to ensure that the first limiting plate 31 of the anchor rod 3 is flush with the concrete surface. The function of the first limiting plate 31 is to accurately position the installation depth of the anchor rod 3 so as to ensure that the installation depth of each anchor rod 3 is consistent. After the pouring is completed and cured, the anchor rod 3 will be firmly anchored in the concrete.

[0030] During installation, first align the guide groove 22 of the fixing plate 2 with the second limiting plate 32 of the anchor rod 3, so that the second limiting plate 32 passes through the guide groove 22 until the fixing plate 2 abuts against the first limiting plate 31. Then, push the fixing plate 2 to move it along the travel groove 23 until the anchor rod 3 reaches the other end of the travel groove 23. At this time, the fastening plate 33 on the anchor rod 3 is located outside the fixing plate 2, while the fixing plate 2 is stuck between the first limiting plate 31 and the fastening plate 33. Next, align the fastening half grooves 13 of the two mounting brackets 11 with the fastening plates on the anchor rod 3. Plate 33 is snapped together. During this process, the two mounting brackets 11 are snapped between the fixed plate 2 and the second limiting plate 32. At this time, the second locking hole 12 of the mounting bracket 11 is connected to the first locking hole 21 of the fixed plate 2. The locking bolts 4 are inserted into the second locking hole 12 and the first locking hole 21 in sequence and tightened, so that the two mounting brackets 11 are firmly installed on the fixed plate 2, ensuring that a stable mechanical interlock is formed between the two mounting brackets 11, the fixed plate 2, and the anchor rod 3, and finally the channel body 1 and the anchor rod 3 are reliably installed and fixed.

[0031] During disassembly, simply unscrew the locking bolts 4, and the two mounting brackets 11 can be removed from the fixing plate 2. Then, push the fixing plate 2 to move it along the travel groove 23 until the anchor rod 3 reaches the guide groove 22. Then the fixing plate 2 can be moved outward and disassembled, thus completing the disassembly of the channel body 1 and the fixing plate 2.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
