[0006] By adopting the above technical solution, when connecting the main body of the channel steel, the workers directly put the outer connector on the surface of the inner connector, and the protrusions on the sides of the outer connector and the inner connector also enter the first and second grooves of the other main body of the channel steel, which also plays the role of increasing the contact area and distributing the pressure. Then the workers pass the bolts through the waist-shaped holes of the two and tighten them, thereby completing the connection of the two main bodies of the channel steel. The connection between the main body of the channel steel and the external structure can also be made by bolts.

[0007] Furthermore, both sides of the external connector are provided with protrusions, and the protrusions on both sides of the external connector are adapted to the first groove.

[0008] By adopting the above technical solution, the two sides of the external connector protrude and extend into the first groove, increasing the contact area between the external connector and the channel steel body, so as to distribute the pressure and thus increase the stability of the structure.

[0009] Furthermore, the inner connector has protrusions on both the upper and lower sides, and the protrusions on both the upper and lower sides of the inner connector are adapted to the second groove.

[0010] By adopting the above technical solution, the inner connector protrudes and extends into the interior of the second groove on both sides above and below, increasing the contact area between the inner connector and the channel steel body, so as to distribute the pressure and thus increase the stability of the structure.

[0011] Furthermore, the inner connector is detachably connected to the outer connector via bolts.

[0012] By adopting the above technical solution, during the docking process, the outer connector is directly fitted onto the surface of the inner connector, and then the bolts are passed through the waist-shaped holes of both and tightened, thereby completing the docking of the two channel steel bodies.

[0013] Furthermore, six bolts are provided.

[0014] By adopting the above technical solution and increasing the number of bolts, the connection between the outer and inner connectors becomes more stable, thereby making the connection between the two channel steels more stable.

[0015] In summary, the present invention has the following main advantages:

[0016] 1. This utility model, through the setting of waist-shaped holes, external connectors, internal connectors and bolts, allows for the connection of two channel steel bodies by directly fitting the external connector onto the surface of the internal connector during the connection process, and then passing the bolts through the waist-shaped holes of both and tightening them; thus facilitating quick on-site splicing and installation.

[0017] 2. By setting the first and second grooves, the outer connector protrudes and extends into the first groove on both sides, and the inner connector protrudes and extends into the second groove on both sides above and below, increasing the contact area between the outer and inner connectors and the channel steel body, so as to distribute the pressure and thus increase the stability of the structure; the structure has good stability.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] Example 1:

[0027] A C-channel steel with three-sided punched waist-shaped holes for easy installation, such as Figure 1-Figure 5 As shown, the structure includes a channel steel body 1, an external connector 5 fixed to one side of the channel steel body 1, and an internal connector 6 fixed to the other side of the channel steel body 1. The outer surface, back, and bottom of the channel steel body 1, the external connector 5, and the internal connector 6 are all provided with waist-shaped holes 2. Bolts 7 pass through the outer surface of the waist-shaped holes 2. The internal connector 6 is detachably connected to the external connector 5 through the bolts 7. The outer surface of the channel steel body 1 is provided with first grooves 3 on both sides, and the upper and lower interior of the channel steel body 1 are provided with second grooves 4. The operator directly puts the external connector 5 onto the surface of the internal connector 6, and then the operator passes the bolts 7 through the waist-shaped holes 2 of the two and tightens them, thereby completing the docking of the two channel steel bodies 1.

[0028] See Figure 1-Figure 5 In the above embodiment, both sides of the outer connector 5 are provided with protrusions, which are adapted to the first groove 3. Both sides of the inner connector 6 are provided with protrusions on the upper and lower sides, which are adapted to the second groove 4. The protrusions of the outer connector 5 extend into the interior of the first groove 3, and the protrusions of the inner connector 6 extend into the interior of the second groove 4, thereby increasing the contact area between the outer connector 5 and the inner connector 6 and the channel steel body 1, so as to distribute the pressure and thus increase the stability of the structure.

[0029] Example 2:

[0030] Based on the above embodiment one, the following settings are now implemented to increase the stability of the connection.

[0031] See Figure 3 In the above embodiment, six bolts 7 are provided, thereby increasing the stability of the connection by increasing the number of bolts.

[0032] The implementation principle of this utility model is as follows: First, during production, the steel is hot-rolled to manufacture the channel steel body 1, the first groove 3, and the second groove 4. Then, the waist-shaped hole 2 is processed by punching or drilling. Then, the outer connector 5 and the inner connector 6 are fixed to the channel steel body 1 by welding to facilitate subsequent on-site installation. At the same time, the outer connector 5 protrudes and extends into the first groove 3 on both sides, and the inner connector 6 protrudes and extends into the second groove 4 on both sides above and below, increasing the contact area between the outer connector 5 and the inner connector 6 and the channel steel body 1, so as to distribute the pressure and thus increase the stability of the structure.

[0033] When connecting the main body 1 of the channel steel, the workers directly put the outer connector 5 onto the surface of the inner connector 6, and the protrusions on the sides of the outer connector 5 and the inner connector 6 also enter the first groove 3 and the second groove 4 of the other main body 1 of the channel steel, which also increases the contact area and distributes the pressure. Then the workers pass the bolt 7 through the waist-shaped hole 2 of the two and tighten it, thereby completing the connection of the two main bodies 1 of the channel steel. The connection between the main body 1 of the channel steel and the external structure can also be made by bolt 7.
