Description

Technical Field

[0001] This utility model relates to the field of pre-embedded channel technology, specifically a pre-embedded channel that is easy to assemble and disassemble. Background Technology

[0002] As an efficient and reliable fixing and connecting component, pre-embedded channels have been widely used in subway tunnels, urban utility tunnels, high-speed railway tunnels and precast concrete components for nuclear power plants due to their ability to achieve precise positioning and convenient installation.

[0003] Current pre-embedded channels typically employ an integrated design of anchor bolts and channels, with the anchor bolts positioned in a fixed manner. When placing the channels within the molds of precast concrete components and assembling them with complex reinforcing cages, these protruding anchor bolts are prone to colliding with and becoming jammed against the crisscrossing reinforcing bars. Furthermore, due to the protruding anchor bolts, the channels cannot be stacked in a planar manner, resulting in significant gaps between each channel and increasing transportation costs. Utility Model Content

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

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

[0006] An easy-to-assemble and disassemble pre-embedded channel includes a channel body and multiple anchor bolt assemblies detachably mounted on the channel body. Two oppositely arranged fixed columns are provided on both sides of the channel body. Multiple evenly distributed snap-fit ​​blocks are provided on the channel body between the two fixed columns. A stop plate is provided on one side of each snap-fit ​​block. A connecting rod is provided on the outer wall of the stop plate. A threaded rod is provided at the end of the fixed column away from the channel body. A limiting plate is provided between the two threaded rods and slidably connected to the connecting rod. A limiting rod corresponding to each snap-fit ​​block is provided on the inner wall of the limiting plate.

[0007] The anchor bolt assembly includes a horizontal plate located above the channel body, with an anchor bolt on the top end face of the horizontal plate. Mounting plates are located on both sides of the channel body on both sides of the horizontal plate, and the mounting plates are provided with snap-fit ​​slots for snap-fit ​​blocks to be inserted.

[0008] The mounting plate has a first limiting hole for inserting a limiting rod, and the first limiting hole is connected to a snap-fit ​​groove.

[0009] The outer wall of the snap-fit ​​block is provided with a second limiting hole for the insertion of the limiting rod.

[0010] There is a mounting slot between two adjacent snap-fit ​​blocks, which allows the mounting plate to be inserted.

[0011] A fastening nut is screwed onto the threaded rod on the outer side of the limiting plate.

[0012] Both the outer end of the connecting rod and the outer end of the threaded rod are equipped with anti-detachment plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The channel body and the detachable anchor bolt assembly of this utility model are two independent components. During transportation, the channel body can be tightly bundled and stacked flat, effectively saving transportation space and reducing transportation costs. The anchor bolt assembly can also be packaged together without interfering with each other. During installation, installers can flexibly choose the installation position of the anchor bolt assembly according to the installation requirements of the construction site, avoiding collisions and jamming with crisscrossing reinforcing bars. By tightening the fastening nut, the limiting plate is pushed to slide inward along the connecting rod, which can lock multiple anchor bolt assemblies at the same time, making the operation process more convenient and faster.

[0024] Example

[0025] refer to Figures 1-5 An easily detachable pre-embedded channel includes a channel body 1 and multiple anchor bolt assemblies 2 detachably mounted on the channel body 1. Two opposing fixing posts 101 are fixedly connected to both sides of the channel body 1. Multiple evenly distributed snap-fit ​​blocks 102 are fixedly connected to the channel body 1 between the two fixing posts 101. These snap-fit ​​blocks 102 provide multiple optional positions for the installation of the anchor bolt assemblies 2. Installers can flexibly adjust the spacing and position of the anchor bolts 202 according to the actual stress requirements of the channel body 1 or the need to avoid specific obstacles. The traditional fixed channel has stronger adaptability. A stop plate 103 is fixedly connected to one side of the snap-fit ​​block 102. The stop plate 103 can limit the displacement of the anchor bolt assembly 2 during installation. A connecting rod 104 is fixedly connected to the outer wall of the stop plate 103. A threaded rod 105 is fixedly connected to the end of the fixing column 101 away from the channel body 1. A limiting plate 106 is provided between the two threaded rods 105 and is slidably connected to the connecting rod 104. A limiting rod 107 corresponding to the snap-fit ​​block 102 is fixedly connected to the inner wall of the limiting plate 106.

[0026] refer to Figure 6 The anchor bolt assembly 2 includes a horizontal plate 201 located above the channel body 1. An anchor bolt 202 is fixedly connected to the top end face of the horizontal plate 201. Mounting plates 203 located on both sides of the channel body 1 are fixedly connected to both sides of the horizontal plate 201. The mounting plates 203 are provided with snap-fit ​​grooves 204 for snap-fit ​​blocks 102 to be inserted. The snap-fit ​​blocks 102 and snap-fit ​​grooves 204 provide initial positioning and vertical bearing capacity for the anchor bolt assembly 2.

[0027] Furthermore, the mounting plate 203 is provided with a first limiting hole 205 for the limiting rod 107 to be inserted into, and the first limiting hole 205 is connected to the snap-fit ​​groove 204.

[0028] Furthermore, the outer wall of the snap-fit ​​block 102 is provided with a second limiting hole 108 for the limiting rod 107 to be inserted. By pushing the limiting plate 106 inward, the limiting rod 107 is inserted into the first limiting hole 205 of the mounting plate 203 and the second limiting hole 108 of the snap-fit ​​block 102, thereby limiting and fixing the anchor bolt assembly 2 and effectively preventing the anchor bolt assembly 2 from loosening or falling off due to vibration during concrete pouring and vibration.

[0029] Furthermore, a mounting slot 109 is provided between two adjacent snap-fit ​​blocks 102, into which the mounting plate 203 can be inserted.

[0030] Furthermore, a fastening nut 110 is screwed onto the threaded rod 105 on the outer side of the limiting plate 106. By tightening the fastening nut 110, the limiting plate 106 is pushed to slide inward along the connecting rod 104, which can lock multiple anchor bolt assemblies 2 at the same time, making the operation process more convenient and faster.

[0031] Furthermore, both the outer end of the connecting rod 104 and the outer end of the threaded rod 105 are provided with anti-detachment plates 111. By setting the anti-detachment plates 111, it is ensured that the limiting plate 106 always maintains a connection with the snap-fit ​​block 102, and the fastening nut is effectively prevented from falling off the threaded rod 105.

[0032] The working principle of this utility model:

[0033] During transportation, the channel body 1 is completely separated from all anchor bolt assemblies 2. The channel body 1 can be tightly bundled and stacked in a flat manner, thereby effectively saving transportation space and reducing transportation costs. The anchor bolt assemblies 2 can also be packaged together without interfering with each other.

[0034] During the installation process, installers can flexibly choose the installation position of the anchor bolt assembly 2 according to the installation requirements of the construction site, that is, install it in different installation slots 109. First, insert the two mounting plates 203 of the anchor bolt assembly 2 into the mounting slots 109 on both sides of the channel body 1, so that the snap-fit ​​slots 204 on the mounting plates 203 are aligned with the snap-fit ​​blocks 102 on the channel body 1. Then, move the anchor bolt assembly 2 so that the snap-fit ​​blocks 102 are fully embedded in the snap-fit ​​slots 204. At this time, the first limiting hole 205 on the mounting plate 203 and the second limiting hole 108 on the snap-fit ​​block 102 are connected to each other. Next, tighten the fastening nut 110, which will push the limiting plate 106 to slide inward along the connecting rod 104. As the limiting plate 106 moves inward, the limiting rod 107 fixed on it will be inserted into the first limiting hole 205 on the mounting plate 203 and the second limiting hole 108 on the snap-fit ​​block 102 at the same time, thereby firmly locking the anchor bolt assembly 2 on the channel body 1 and ensuring that it cannot be detached from the channel body 1. At this time, the horizontal plate 201 is close to the top of the channel body 1, and the anchor bolt 202 extends vertically upward.

[0035] 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.

[0036] 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.
