[0045] Hereinafter, the coupling device of a building module according to the present invention will be described in detail together with the attached drawings.

[0047]

[0048] As illustrated in FIGS. 1 to 7, the present invention relates to a coupling device (100) for a building module that allows the building module to be easily expanded by securing the module frame of the building module with a single touch by docking, and also allows the secured building module to be easily released and separated.

[0049]

[0050] In addition, the present invention relates to a coupling device (100) for an axle module that facilitates the expansion and dismantling of a building module by providing a structure that allows a towing hook to be connected to a docking guide block coupled to a module frame.

[0051]

[0052] The coupling device (100) of such a building module is largely composed of two parts, which may consist of a cylindrical connector part disposed in the lower corner area of ​​the module frame (10) of the building module having a square housing structure, and a docking guide block (30) disposed in the upper corner area of ​​the module frame (10) to restrain and release the connector part (20).

[0053]

[0054] Here, the module frame (10) may be formed in the shape of an H-beam or a square pipe, and in the embodiment of the present invention, the module frame (10) is formed in the shape of an H-beam.

[0055]

[0056] As shown in FIG. 2, the connector part (20) may be composed of a connector pin (21) that is coupled downward to the lower edge area of ​​the module frame (10) and a guide column (22) that is coupled downward to the module frame (10) at a set distance from the connector pin (21).

[0057] Here, the connector pin (21) functions to fix the module frame (10) by being constrained by docking to the docking guide block (30), and the guide column (22) functions as a guide for docking the connector pin (21) in the correct position.

[0058] At this time, the connector pin (21) may be configured with a plurality of ring protrusions (211) formed on its outer surface so that it can be secured to the docking guide block (30).

[0059] And as shown in FIGS. 5 and 6, the guide column (22) has a conical wedge shape at its end and is primarily docked to the docking guide block (30) before the connector pin (21) docks, thereby functioning to align the position of the connector pin (21).

[0060] To this end, the guide column (22) may have a structure with an enlarged diameter and length compared to the connector pin (21), and may also serve an additional function of increasing the coupling and structural safety between the module frames (10).

[0061]

[0062] As shown in FIG. 4, the docking guide block (30) is a structure that reinforces the upper corner area of ​​the module frame (10) to distribute and support the load of the stacked building modules, and has a connecting groove (31) formed therein to fix a connecting bar (40) that can be connected to the module frame (10) of the building modules arranged on the front / rear / left / right side.

[0063] The above docking guide block (30) increases structural rigidity through the connecting bar (40), and additionally enables upper / lower docking of the module frame (10), as well as connection in the front / rear / left / right directions.

[0064] The above docking guide block (30) may be configured to include a connecting groove (31) formed across the center in three equal parts so as not to cause deviation of the connecting bar (40) to be seated, a restraining means (34) for restraining a connector pin (21) that is docked and embedded in one of the divided areas, and a guide hole (32) formed in one of the divided areas to guide a guide column (22).

[0065] Also, as shown in FIG. 9, the docking guide block (30) has a fastening hole (35) formed in an area divided equally with the connecting groove (31) in between for connecting the towing hook (50), thereby enabling the module frame (10) to be safely moved and towed by a crane.

[0066] The above fastening hole (35) functions to position the towing hook (50) at a designated location, thereby providing a structure that allows the towing module frame (10) to be moved stably without weight imbalance.

[0067] In addition, as shown in FIG. 4, the connecting groove (31) has a structure in which a connecting column (311) is formed protrudingly to strengthen the structural bonding force with the connecting bar (40).

[0068] These connecting columns (311) can also serve an additional function of positioning the connecting bar (40) at the correct connection position.

[0069] Here, the connecting bar (40) is structured to be connected in a cantilevered form so as to be connected to the docking guide block (30) of an adjacent building module.

[0070] The above restraining means (34) functions to restrain the docking connector pin (21) with a single touch, as shown in FIG. 7, so that the extension of the module frame (10) can be expanded quickly.

[0071] As shown in FIG. 4, this restraining means (34) is a structure embedded in a buried hole (33) formed in a docking guide block (30), and is composed of a housing (341), a restraining piece (342), an elastic coil (C), and a cap bolt (343).

[0072] The above housing (341) has a tapered upper structure and is configured to be embedded in a buried hole (33) formed in the docking guide block (30).

[0073] And the restraining piece (342) is located on the inner upper part of the housing (341), and the restraining piece (342) may be divided into equal intervals so that its diameter can be expanded and contracted.

[0074] That is, when the restraining piece (342) is positioned in the upper tapered portion of the housing (341), the inner diameter is reduced, and when it is positioned in the lower portion of the housing (341), it is expanded according to the size of the inner diameter of the housing.

[0075] At this time, the restraining piece (342) may be configured with a plurality of toothed stopper blades (342a) formed thereon so that when the inner diameter is reduced, the ring projection (211) of the connector pin (21) can be restrained in the reverse direction.

[0076] That is, as shown in Fig. 7(b), the stopper blade (342a) restrains the ring projection (211) in the reverse direction (upward direction) to prevent the connector pin (21) from coming off.

[0077] As shown in FIG. 7 (a) and (b), the above elastic coil (C) is compressed when lowered together with the restraining piece (342) by docking the connector pin (21), and when the entry of the connector pin (21) is completed, it functions to raise only the restraining piece (342) with an expanded inner diameter so that the connector pin (21) restrains the ring projection (211).

[0078] The above cap bolt (343) is fastened to the bottom of the housing (341) and functions to support the restraining piece (342) and the elastic coil (C) while preventing detachment.

[0079] These cap bolts (343) are structured to be exposed on the module frame (10) so that they can be easily separated and connected from the inside and outside of the building module.

[0080] As shown in Fig. 8, when the cap bolt (343) is separated from the housing (341), the restraining piece (342) and the elastic coil (C) embedded in the housing (341) fall off, thereby allowing the restraint of the connector pin (21) to be released.

[0081] Therefore, when separating the building module, it is possible to do so by separating the cap bolt (343), restraining the connector pin (21), and releasing the restraining piece (342).

[0082]

[0083] FIG. 10 is a cross-sectional view showing a connecting bar of another embodiment.

[0084] As shown in FIG. 10, in another embodiment,

[0085] To offset horizontal vibrations, the connecting bar (40) has a split structure and is connected to one another through a guide hole (41) and a guide rod (42), and the guide hole (41) may be configured with an elastic coil (C) embedded therein to offset horizontal vibrations.

[0086] Here, the guide hole (32) and guide rod (42) can be formed as a pair.

[0087] Accordingly, the connecting device (100) of the building module of the present invention can secure structural stability by offsetting vertical and horizontal vibrations caused by earthquakes or external winds with the connecting bar (40).

[0088] Vertical vibration can be controlled by installing a conventional damper (not shown) on the floor surface of the building module that is in contact with the ground.

[0089]

[0090] The embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; therefore, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
