[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, a mechanical connection module for connecting prefabricated beams and prefabricated piles includes a sleeve 1, an intermediate nut 2, a first steel bar 3, a socket 4 and a second steel bar 5.

[0032] like Figure 3 As shown, the inner wall of one end of the sleeve 1 is provided with a first internal thread 6 extending inwardly along the axial direction thereof; the other end of the sleeve 1 is provided with a step stopper 7 extending inwardly along the axial direction thereof.

[0033] like Figure 4 As shown, the outer wall of the intermediate nut 2 is provided with a first external thread 8, the first external thread 8 is matched with the first internal thread 6, and the intermediate nut 2 is threadedly connected in the sleeve 1; the inner wall of the intermediate nut 2 is provided with a second internal thread 9.

[0034] like Figure 5 As shown, a second external thread 10 is provided on one end of the first steel bar 3 , and the second external thread 10 is matched with the second internal thread 9 . The first steel bar 3 is threadably connected to the intermediate nut 2 via the matching threads of the second external thread 10 and the second internal thread 9 .

[0035] like Figure 6 As shown, the outer diameter of the socket 4 is larger than the inner diameter of the step limit portion 7 and smaller than the inner diameter of the sleeve 1; the socket 4 is located in the sleeve 1 and close to one end of the step limit portion 7; a third internal thread 11 is provided on the inner wall of the socket 4.

[0036] like Figure 7 As shown, a third external thread 12 is provided on one end of the second steel bar 5 , and the third external thread 12 is matched with the third internal thread 11 . The second steel bar 5 is threadedly connected to the socket 4 through the cooperation of the third external thread 12 and the third internal thread 11 .

[0037] In this embodiment, if Figure 1 As shown, in order to improve the bonding strength between the sleeve 1 and the subsequently poured concrete, the cross section of the outer wall of the sleeve 1 is a regular hexagon.

[0038] In this embodiment, in order to facilitate the movement of the sleeve 4 in the sleeve 1, as shown in FIG. Figure 3As shown, the inner wall of the sleeve 1 is provided with a smooth wall area 13 at one end between the step limit portion 7 and the first internal thread 6, which effectively reduces the friction between the socket and the inner wall of the sleeve.

[0039] In this embodiment, the inner wall of the intermediate nut 2 facing the end of the first steel bar 3 and the inner wall of the socket 4 facing the end of the second steel bar 5 both have rounded corners 14, which facilitates the introduction of the first steel bar 3 or the second steel bar 5 and improves installation efficiency.

[0040] like Figure 2 As shown, when installing the above-mentioned mechanical connection module, the first steel bar 3 is first installed on the steel skeleton of the prefabricated pile, and the middle nut 2 is threadedly connected to the end of the first steel bar 3; the socket 4 is threadedly sleeved on one end of the second steel bar 5, and the socket 4 is sleeved in the sleeve 5, and the second steel bar 5 is installed on the steel skeleton of the prefabricated beam. Due to the effect of the step limiting part 7 in the sleeve 1, the socket 4 will not fall out of the sleeve 1, and the inner wall of the other end of the sleeve 1 is threadedly connected to the middle nut 2 to achieve installation. Since one end of the socket 4 can move freely in the sleeve 1, the installation difficulty between the prefabricated pile steel skeleton and the prefabricated beam skeleton is reduced.
