Description

Technical Field

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

[0002] In subway construction, the subway pre-embedded channel is a key component used to fix and support various equipment and pipelines. It is usually pre-embedded in the concrete structure to provide a reliable connection foundation for subsequent equipment installation.

[0003] The pre-embedded channel structure of subway mainly consists of the channel body and anchor bolts. Currently, the connection between the channel body and the anchor bolts is generally achieved through hot forging. The channel body has mounting holes corresponding to the anchor bolt installation positions, and the anchor bolts are connected to the corresponding mounting holes in the channel body with inserts. During assembly, the inserts on the anchor bolts are heated to a suitable temperature. Workers then remove the rod end of the anchor bolt and insert the insert into the mounting hole in the channel body. External equipment holds one end of the anchor bolt, while another device presses the insert, transforming it from a cylindrical shape into a disc shape, thus completing the connection between the anchor bolt and the channel body.

[0004] However, this method has many drawbacks. Firstly, the hot forging process requires heating the metal to a high temperature, which not only consumes a large amount of energy, increasing energy costs in the production process, but also may adversely affect the properties of the metal material, such as causing a decrease in mechanical properties and uneven microstructure, thus affecting the overall structural strength and stability of the embedded channel. Secondly, the hot forging process is relatively complex, requiring high technical skills from both equipment and operators, resulting in relatively low production efficiency and increased production cycle and cost. Furthermore, the joints formed by hot forging may loosen or deform during long-term use due to vibrations and loads from subway operation, reducing the reliability and safety of the embedded channel and increasing the difficulty and cost of later maintenance and repair. In addition, this operation is currently mostly performed manually, which carries certain risks. Summary of the Invention

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please see Figures 1-4 This application provides the following technical solutions:

[0040] A subway pre-embedded channel includes a channel body 1 and several anchor rods 2. The assembled structure of the channel body 1 and anchor rods 2 is basically a conventional pre-embedded channel structure. Considering its ease of application, the main body of both is not significantly modified, so there is no difference in its use compared to existing pre-embedded channels. The main improvement of this solution is in the assembly structure of the anchor rods 2 and the channel body 1. The anchor rod 2 includes a rod body 21 and an installation component 22 fixed to one end of the rod body 21. The rod body 21 can adopt a conventional anchor rod structure, which does not require modification. The installation component 22 of the anchor rod 2 is generally a square tubular structure, and the installation component 22 and the rod body 21 are coaxial. A through groove 23 is opened in the middle of the installation component 22. The through groove 23 is opened along the axial direction of the installation component 22, and the through groove 23 divides the installation component 22 into two symmetrical halves. The two symmetrical halves form an approximate "<" shape. The mounting part 22 corresponding to the anchor rod 2 is provided with a mounting hole on the groove body 1; the mounting part 22 can be inserted into the groove body 1 through the mounting hole on the groove body 1, and the state is as follows. Figure 6 and Figure 7 As shown, in this state, the anchor rod 2 and the groove 1 are only plugged in, but not fixed.

[0041] After the mounting part 22 and the mounting hole of the groove 11 are connected, a stamping device can be used to push the mounting part 22 apart from the middle, causing it to bend towards both sides of the inner wall of the groove 1, presenting a state as shown. Figure 8 and Figure 9 As shown. At this point, the mounting part 22 is flattened to fit against the inner wall of the groove 1, thus forming a preliminary connection. Based on this, welding can then be performed.

[0042] This method achieves the connection and assembly of anchor bolt 2 and groove body 1 by welding. Compared with the traditional hot forging connection method, it has lower equipment requirements and is safer. Furthermore, the welding method allows the use of existing welding robots, greatly improving worker safety.

[0043] Based on the above implementation scheme, the mounting hole of the groove 1 is a square through hole corresponding to the mounting part 22. The mounting hole can also be a round hole, but considering the foolproof nature of installation, it is easier to operate by making it a square hole.

[0044] Based on the above implementation scheme, the tank 1 also includes an installation groove 11, such as... Figure 8 and Figure 9 As shown, the mounting groove 11 is formed inside the groove body 1 and is located on the groove wall where the mounting hole is located; the depth of the mounting groove 11 corresponds to the thickness of the mounting component 22.

[0045] The mounting groove 11 can be opened in a similar form to the attached diagram of this scheme, that is, it can be directly opened as a groove equal to the length of the groove body 1. Alternatively, it can be opened in segments corresponding to each mounting hole, as long as the mounting part 22 can be bent and embedded into the mounting groove 11.

[0046] By setting the mounting groove 11, the fitting effect between the mounting part 22 and the groove 11 can be better, thereby improving the firmness after subsequent welding.

[0047] Based on the above implementation scheme, and considering the protection of the channel after processing, this scheme also includes a protective component, which includes an end protector 3 and a side protector 4. The end protector 3 is inserted into the axial end of the channel body 1 to protect the end of the channel body 1. The side protector 4 is shaped to correspond to the slotted side of the channel body 1 and can be fastened to the outer surface of the channel body 1 away from the anchor rod 2; the side protector 4 is a long strip plate made of elastic material.

[0048] Because pre-embedded channels often require large-scale transportation without dedicated packaging for protection, they are usually bundled together during transport. To address this issue, side protection components 4 are installed on the more critical slotted side to provide a certain level of protection.

[0049] Based on the above implementation plan, participate Figure 5 The end protector 3 is a block, and a limiting hole 31 is provided on the end protector 3. The opening direction of the limiting hole 31 is perpendicular to the length direction of the groove 1. The limiting hole 31 penetrates the end protector 3 and is provided with internal thread. A limiting element 33 is provided corresponding to the limiting hole 31. The limiting element 33 is a bolt, and the end protector 3 is fixedly connected to the groove 1 through the limiting element 33.

[0050] When using it, first insert the end protector 3 into the end of the groove 1, so that it becomes Figure 4As shown in the figure, the limiting member 33 is then screwed on. After passing through the end protector 4, the limiting member 33 abuts against the inner wall of the groove 11. As the limiting member 33 continues to be screwed on, the end protector 4 and the inner wall of the groove 11 on the side away from the anchor rod 2 are tightly attached, thereby completing the fixation of the end protector 4.

[0051] Based on the above implementation scheme, the end protector 3 is also provided with a connecting groove 32, which is a slot opened on the outer side of the axial end of the end protector 3 facing the groove body 1. A connector 5 is provided corresponding to the connecting groove 32. In this scheme, both the connecting groove 32 and the connector 5 are "convex" shaped structures. The connector 5 is a block, and the length of the connector 5 is twice the length of the connecting groove 32. The connector 5 can be inserted into the connecting groove 32.

[0052] The connector 5 has two connecting holes 51 at both ends. The connecting holes 51 are through holes that pass through the connector 5. When the connector 5 is inserted into the connecting groove 32, the connecting holes 51 and the limiting holes 31 on the end protector 3 are coaxial.

[0053] With this structure, the two grooves 1 can be joined together in the longitudinal direction using the connector 5. The connector 5 joins the two grooves together. If it is necessary to increase the length of the groove during use, the connector 5 of this solution can be combined with the end protection member 3.

[0054] Based on the above implementation scheme, through holes are provided at both ends of the side protection component 4 corresponding to the limiting holes 31. By using the interfaces of the openings in the side protection component 4, the limiting component 33 can be used to fix the end protection component 3 and the side protection component 4 at the same time, ensuring that the side protection component 4 will not fall off during transportation.
