[0028] The top four corners of the I-shaped stiffener 1 are provided with threaded holes corresponding to the vertical force reinforcement module and the top of the vertical force reinforcement module is fixed in the reinforcement module mounting groove by the fixing bolts. As shown in FIG. 1, the upper surfaces of the left and right sides of the bottom of the I-shaped stiffener 1 are provided with stripe friction surfaces to increase the mechanical bite force, thereby improving the stability of the connection, enhancing the fixing effect on the horizontal modular beam, and improving the seismic performance.

[0030] The left and right sides of the large gear 21 are symmetrically connected to the vertical force application module, respectively. The vertical force application module includes the upper locking cover 27 fixed in the reinforcement module mounting groove by the fixing bolts, which is used to fix and limit the overall vertical force application module. And the middle part of the lower surface of the upper locking cover 27 is provided with the inner groove of the upper locking cover 29. In this embodiment, the thickness of the inner groove of the upper locking cover 29 is set to one third of the overall thickness, thereby conveniently providing sufficient mounting space for the internal structure.

When the second pinion gear 210 rotates, it drives the threaded gear 2123 to rotate simultaneously within the cylindrical tube 2122. And the bottom of the threaded gear 2123 is welded with the disc 2124 having the same inner diameter as the cylindrical housing 2122, enabling the threaded gear 2123 to move vertically up and down. A displacement distance is defined between the disc 2124 and the bottom of the cylindrical housing 2122 to achieve the function of controlling vertical force.

[0036] As shown in FIG. 3, the inner sides of both ends of the upper locking cover 27 and the arc-shaped limit plate 213 are correspondingly provided with spring grooves 215, respectively, and springs 216 are arranged in the spring grooves 215, facilitating the mounting of pre-alignment, and providing elastic force when controlling the vertical force, thereby enabling better controlling of the magnitude of the vertical force.

Although the present disclosure has been described in detail with reference to the preferred examples, those of ordinary skill in the art should understand that the technical solutions of the present disclosure may still be modified or equivalently replaced.

When the second pinion gear 210 rotates, it drives the threaded gear 2123 to rotate simultaneously within the cylindrical tube 2122. And the bottom of the threaded gear 2123 is welded with the disc 2124 having the same inner diameter as the cylindrical housing 2122, enabling the threaded gear 2123 to move vertically up and down. A displacement distance is defined between the disc 2124 and the bottom of the cylindrical housing 2122 to achieve the function of controlling vertical force.

[0036] As shown in FIG. 3, the inner sides of both ends of the upper locking cover 27 and the arc-shaped limit plate 213 are correspondingly provided with spring grooves 215, respectively, and springs 216 are arranged in the spring grooves 215, facilitating the mounting of pre-alignment, and providing elastic force when controlling the vertical force, thereby enabling better controlling of the magnitude of the vertical force. The lower surface of the arc-shaped limiting plate 213 has the arc-shaped structure protruding downward, and the surface is roughened, facilitating the clamping and fixing of horizontal modular beams.

[0037] The prefabricated channel steel beam 3 is arranged at the outer end of the horizontal modular beam and embedded in grooves on both sides of the I-shaped stiffener 1. The upper surface of the prefabricated channel steel beam 3 is provided with an arc groove 31 matched with the arc-shaped limit plate 213. The surface of the curved groove 31 is roughened, which can better fix the arc-shaped limit plate 213. The prefabricated channel steel beam 3 has a striped treatment on its lower surface for adapting with the corresponding striped friction surface, effectively preventing separation between the prefabricated channel beam 3 and the I-beam reinforcement 1, thereby enhancing seismic performance.

[0038] Therefore, by adopting the modular horizontal channel steel beam connection device described above, the present disclosure can solve the problems of low construction efficiency, stress concentration at the joints and poor modular adaptability caused by insufficient standardization of the connection interface and the discontinuous force transmission path in existing connection devices, thereby enhancing structural integrity and seismic performance.

[0039] Finally, it should be noted that the above embodiments are merely used for describing the technical solutions of the present disclosure, rather than limiting the same. Although the present disclosure has been described in detail with reference to the preferred examples, those of ordinary skill in the art should understand that the technical solutions of the present disclosure may still be modified or equivalently replaced. However, these modifications or substitutions should not make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present disclosure.
