Description

Technical Field

[0001] The utility model relates to a component installation structure in rail transportation, in particular to a pre-buried sleeve and external hanging channel installation structure. Background Art

[0002] During the prefabrication and pouring of the segments in rail transit, the embedded grooves need to be positioned and installed on the steel mold. The existing conventional installation method generally uses bolt connections to fix the embedded grooves on the steel mold. Therefore, threaded holes need to be drilled on the steel mold. During the installation process, a wrench needs to be used to gradually tighten the embedded grooves and the steel mold. The operation efficiency is low. In addition, the high-frequency vibration during concrete pouring will also cause the threads to retreat, resulting in loose connections, poor connection strength, and poor durability. It will also cause the embedded grooves to move, resulting in position deviations, looseness, and other problems, which seriously affect the subsequent installation quality and construction efficiency. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an embedded sleeve and external groove installation structure which has a simple structural design, is quick and convenient to install and can effectively avoid displacement of the embedded groove, thereby ensuring installation quality and construction efficiency.

[0004] In order to solve the above technical problems, the utility model provides an embedded sleeve and an external groove installation structure, including a steel mold and an embedded groove for installation on the steel mold, the embedded groove is provided with a plurality of installation holes for passing the fixing pin, the steel mold is provided with pin holes corresponding to the positions of the respective installation holes, the fixing pin is made of a material capable of producing elastic deformation, the diameter of the pin hole is smaller than the diameter of the installation hole, the fixing pin can pass through the installation hole into the pin hole and be fixed in the pin hole by elastic deformation and expansion of the fixing pin.

[0005] The front section of the fixing pin is configured as a conical surface section.

[0006] The length of the conical surface section is equal to or greater than the thickness of the steel mold.

[0007] The front end edge of the tapered surface segment is provided with a chamfer serving as a guide surface.

[0008] The fixing pin is made of nylon material.

[0009] A plurality of embedded sleeves are installed on the embedded groove.

[0010] Each of the embedded sleeves is arranged between adjacent mounting holes.

[0011] The advantages of the utility model are:

[0012] During the installation process, you only need to insert the fixing pin into the pin hole through the installation hole and directly hammer the fixing pin to use the elastic deformation and expansion of the fixing pin to achieve the fixed connection between the embedded groove and the steel mold. The installation is very quick and convenient. There is no need to use a wrench to gradually tighten the embedded groove and the steel mold, which greatly improves the working efficiency. In addition, it also avoids the problem of loosening of the thread, ensures the connection strength and durability of the embedded groove, and has very good reliability, thereby ensuring the subsequent installation quality and construction efficiency.

[0016] The embedded sleeve and external groove installation structure of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] As shown in the figure, the embedded sleeve and external groove installation structure of the utility model comprises a steel mold 1 and an embedded groove 2 for installation on the steel mold, the embedded groove 2 is arranged with a plurality of mounting holes 4 for passing the fixing pin 3, a plurality of embedded sleeves 8 are installed on the embedded groove 2, each embedded sleeve 8 is arranged between adjacent mounting holes, and the steel mold 1 is arranged with corresponding mounting holes. Pin hole 5 , the fixing pin 3 is made of a material capable of producing elastic deformation, for example: Fixed pin 3 It can be made of nylon material, and the diameter of the pin hole 5 is smaller than Mounting holes 4 The diameter of the fixing pin 3 can be inserted into the pin hole through the mounting hole and fixed in the pin hole through elastic deformation and expansion of the fixing pin, thereby fixing the embedded groove on the steel mold.

[0018] Furthermore, a conical section 6 may be provided at the front section of the fixing pin 3, and the length of the conical section 6 is equal to or greater than the thickness of the steel mold. Thus, the conical section can be used to conveniently enter the pin hole to prevent the problem of misalignment of the hole position, thereby improving the convenience and reliability of the connection. On the other hand, in conjunction with the elastic deformation ability of the fixing pin itself, it plays a role in fixing the embedded groove to prevent it from falling off. Furthermore, a chamfer 7 serving as a guide surface is provided at the edge of the front end of the conical section 6, thereby utilizing the guiding inclined surface of the chamfer to further improve the convenience and reliability of installation.
