Description

Technical Field

[0001] This utility model relates to the field of railway channel technology, specifically a pre-embedded channel with high connection strength. Background Technology

[0002] With the development of rail transit, high-speed rail, subways, and other rail transit facilities are under construction throughout the country, making rail transit projects key engineering projects. Currently, when installing components such as overhead contact line booms, especially in tunnels, pre-embedded channels are typically used. This eliminates the need for drilling holes in the concrete, preserving the concrete's structure and strength, as well as its waterproofing effect, and ensuring a long service life.

[0003] However, the existing pre-embedded channels are mainly welded together by C-shaped channels and multiple anchor rods with a spacing of no more than 250 mm. After being embedded in concrete, they mainly rely on the anchor rods connected to the channel to bear the force. Only the channel opening is left flush with the concrete working surface. T-bolts are installed at the channel opening to connect and fix it to the contact wire boom, etc.

[0004] The existing pre-embedded channels mainly rely on anchor rods connected to the channel body for stress. The connection between the anchor rods and the channel body is mainly achieved through welding and riveting. If the strength of the welding or riveting is insufficient and the anchor rods detach from the channel body, or if the anchor rods break during the stress process, the mechanical properties of the pre-embedded channels will fail. This will bring huge safety hazards to the high-speed rail, subway and other rail transit facilities that are in operation, and seriously threaten personal safety and property safety. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a pre-embedded channel with high connection strength. This addresses the problem that existing pre-embedded channels mainly rely on anchor rods connected to the channel body for stress support. The connection between the anchor rods and the channel body is mainly achieved through welding and riveting. If the welding or riveting strength is insufficient and the anchor rods detach from the channel body, or if the anchor rods break during stress, the mechanical properties of the pre-embedded channel will fail, posing a huge safety hazard to high-speed rail, subway, and other rail transit facilities in operation, and seriously threatening personal and property safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength pre-embedded channel includes a channel body. Two opposing extension plates are provided on the side of the channel body away from the channel opening. Several equally spaced anchor rods are provided on the channel body between the two extension plates. Anti-detachment rings are fixedly connected to the anchor rods. First fixing plates are symmetrically arranged on both sides of the anchor rods at the top of the anti-detachment rings. First fixing holes for inserting fixing bolts are provided through the first fixing plates. Base plates are located between the two extension plates on both sides of the anchor rods. A first toothed surface is provided on the top of the base plate. A mounting plate parallel to the base plate is provided above the base plate. A second toothed surface meshing with the first toothed surface is provided at the bottom of the mounting plate. A connecting inclined plate is provided on the top of the mounting plate. A clamping plate whose inner sidewall fits against the outer end face of the anchor rod is provided on the connecting inclined plate. Second fixing plates are symmetrically fixedly connected to both sides of the clamping plate. Second fixing holes communicating with the first fixing holes are provided through the second fixing plates.

[0008] As a further embodiment of this utility model, the top of the extension plate is slidably connected with a plurality of reinforcing cover plates corresponding one-to-one with the mounting plate. A semi-threaded rod is provided on one side of the top of the reinforcing cover plate, and two adjacent semi-threaded rods can cooperate to form a complete threaded rod for fixing with a connecting nut.

[0009] As a further embodiment of this utility model, a limiting block is fixedly connected to the bottom end face of the reinforcing cover plate, and a limiting groove is provided on the top end face of the extension plate to allow the limiting block to move.

[0010] As a further embodiment of this utility model, the mounting plate is symmetrically fixedly connected to the two sides of the mounting plate with an L-shaped connecting plate, and the top end face of the extension plate is provided with a connecting groove for the connecting plate to be inserted.

[0011] As a further embodiment of this utility model, a positioning block is provided on the second tooth surface, and a positioning groove is provided on the first tooth surface that penetrates the base plate so that the positioning block can be inserted.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention improves the connection strength between the anchor bolt and the trench, preventing anchor bolt breakage under stress. By firmly fixing the clamping plate to the anchor bolt and the mounting plate to the trench, and by connecting the mounting plate and the clamping plate with a connecting inclined plate, the stability and strength of the connection between the anchor bolt and the trench are greatly enhanced. The connection strength between the mounting plate and the trench is further improved by the connecting plate and the connecting groove. The anti-detachment ring ensures that even if local cracking or breakage occurs at the connection between the anchor bolt and the trench, the anchor bolt and the trench can still maintain a certain connection, preventing the anchor bolt from detaching from the trench, extending the service life of the pre-embedded trench, and improving safety.

[0022] Example

[0023] refer to Figures 1-5A high-strength pre-embedded channel includes a channel body 1. Two opposing extension plates 101 are fixedly connected to the side of the channel body 1 furthest from the opening. A plurality of equally spaced anchor rods 2 are fixedly connected to the channel body 1 between the two extension plates 101. Anti-detachment rings 201 are fixedly connected to the anchor rods 2. The anti-detachment rings 201 ensure that even if local cracking or breakage occurs at the connection between the anchor rod 2 and the channel body 1, the anchor rod 2 and the channel body 1 can still maintain a certain connection, preventing the anchor rod 2 from detaching from the channel body 1, extending the service life of the pre-embedded channel, and improving safety. First fixing plates 202 are symmetrically fixedly connected to both sides of the anchor rod 2 at the top of the anti-detachment rings 201. First fixing holes 203 are provided through the first fixing plates 202 for inserting fixing bolts 3. Base plates 102 are provided on both sides of the anchor rod 2 between the two extension plates 101. 102 is fixedly connected to the groove 1. The top of the bottom plate 102 is provided with a first toothed surface 103. The top of the bottom plate 102 is provided with a mounting plate 4 parallel to it. The bottom of the mounting plate 4 is provided with a second toothed surface 401 that meshes with the first toothed surface 103. When the mounting plate 4 is installed and connected to the groove 1, the second toothed surface 401 on the mounting plate 4 and the first toothed surface 103 on the bottom plate 102 mesh with each other, increasing the friction between the mounting plate 4 and the bottom plate 102, thereby improving the stability of the anchor rod 2 under force. The top of the mounting plate 4 is fixedly connected with a connecting inclined plate 402. The connecting inclined plate 402 is provided with a clamping plate 403 whose inner side wall fits against the outer end face of the anchor rod 2. The connecting inclined plate 402 and the clamping plate 403 are fixedly connected. The clamping plate 403 is symmetrically fixedly connected with a second fixing plate 404 on both sides. The second fixing plate 404 is provided with a second fixing hole 405 that communicates with the first fixing hole 203.

[0024] Furthermore, the top of the extension plate 101 is slidably connected with a plurality of reinforcing cover plates 104 corresponding one-to-one with the mounting plate 4. A semi-threaded rod 105 is fixedly connected to one side of the top of the reinforcing cover plate 104, and two adjacent semi-threaded rods 105 can cooperate to form a complete threaded rod for fixing the connecting nut 5.

[0025] Furthermore, a limiting block 106 is fixedly connected to the bottom end face of the reinforcing cover plate 104, and a limiting groove 107 is provided on the top end face of the extension plate 101 to allow the limiting block 106 to move. Through the setting of the limiting groove 107 and the limiting block 106, not only does the reinforcing cover plate 104 not detach from the connection with the extension plate 101 and always maintain the connection relationship with the extension plate 101, but the displacement of the reinforcing cover plate 104 can also be limited.

[0026] Furthermore, the mounting plate 4 is symmetrically fixedly connected to the two sides of the mounting plate 4 with an L-shaped connecting plate 407, and the top end face of the extension plate 101 is provided with a connecting groove 109 for the connecting plate 407 to be inserted.

[0027] Furthermore, a positioning block 406 is provided on the second tooth surface 401, and a positioning groove 108 is provided on the first tooth surface 103 that penetrates the bottom plate 102 and allows the positioning block 406 to be inserted. Through the setting of the positioning groove 108 and the positioning block 406, the installation of the mounting plate 4 and the groove 1 can be positioned.

[0028] The working principle of this utility model:

[0029] In use, first pull the reinforcing cover plate 104 to move the two adjacent reinforcing cover plates 104 to one end away from each other. Then, align the positioning block 406 on the mounting plate 4 with the positioning groove 108 on the groove body 1 and insert it. At the same time, the second toothed surface 401 on the mounting plate 4 and the first toothed surface 103 on the groove body 1 mesh with each other, and the connecting plate 407 on the mounting plate 4 is inserted into the connecting groove 109 on the groove body 1. At this time, the second fixing hole 405 on the clamping plate 403 is connected to the first fixing hole 203 on the anchor rod 2. Insert the fixing bolts 3 into the second fixing hole 405 and the first fixing hole 203 in sequence, thereby securing the clamping plate 403. 3. The anchor rod 2 is firmly fixed together. Then, the reinforcing cover plate 104 is pushed to move the two adjacent reinforcing cover plates 104 toward each other. The semi-threaded rods 105 at the top of the two adjacent reinforcing cover plates 104 cooperate to form a complete threaded rod. Finally, the connecting nut 5 is screwed onto the complete threaded rod, thereby limiting and fixing the two reinforcing cover plates 104, so that the connecting plate 407 is firmly locked in the connecting groove 109, and then the mounting plate 4 and the groove 1 are firmly fixed together. The mounting plate 4 and the clamping plate 403 are fixedly connected by the connecting inclined plate 402, so that the connection stability and connection strength between the anchor rod 2 and the groove 1 are greatly improved.
