Description

[Technical field]

[0001] The present invention relates to a modular unit coupling device, and more particularly to a modular unit coupling device for coupling adjacent modular units. [Background technology]

[0002] Modular construction is a system in which modular units manufactured in factories are assembled on-site to complete a building. The application of this modular construction system can reduce construction time by 50~60% compared to existing construction methods, and because modular units are manufactured in factories, they can be easily assembled, disassembled, moved, and reused.

[0003] Modular units are stacked between modular units at the construction site. In the case of large-space modules, the modular units are configured with long spans, so excessive sagging and vibration of the beams that make up the modular units may occur, and the beam specifications may increase to realize long-span modules, which may increase the floor height.

[0004] To supplement this, a technology was proposed to form a bottom diaphragm by connecting the beams of the units together to improve the structural performance of the beams, but this generally requires bolt connections, which may cause interference with the finish. This increases the amount of work required for on-site finishing, and there are problems with the need to secure a work space due to the limited space.

[0038] In the following description, the direction in which the X-axis in FIG. 1 faces is defined as the forward direction, the direction in which the Y-axis faces is defined as the rightward direction, and the direction in which the Z-axis faces is defined as the upward direction.

[0039] As shown in FIG. 1, a modular unit connection device 1 according to an embodiment of the present invention serves to connect a first upper modular unit 100, a second upper modular unit 300, a first lower modular unit 200 and a second lower modular unit 400.

[0040] In this case, the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400 are the same modular unit, and their names are determined according to their positions.

[0041] That is, as shown in FIG. 1, the first upper modular unit 100 is a modular unit arranged at the upper left side, the second upper modular unit 300 is a modular unit arranged at the upper right side, the first lower modular unit 200 is a modular unit arranged at the lower left side, and the second lower modular unit 400 is a modular unit arranged at the lower right side.

[0042] As shown in FIG. 1, the first upper modular unit 100 includes a rectangular plate-shaped bottom, bottom beams arranged at the four corners of the bottom to support the bottom, a ceiling portion arranged opposite the bottom, ceiling beams arranged at the four corners of the ceiling portion to support the ceiling portion, and columns extending vertically to support the ceiling portion and the four vertices of the bottom portion.

[0043] In this case, the bottom beam at the lower right of the first upper modular unit 100 will be described as a first bottom beam 110. As shown in Fig. 2, the first bottom beam 110 extends in the front-rear direction.

[0044] Since the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400 are the same modular unit, the description of the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400 will be substituted for the description of the first upper modular unit 100.

[0045] In this case, the bottom beam at the lower left of the second upper modular unit 300 will be described as a second bottom beam 310. As shown in FIG. 2, the second bottom beam 310 extends in the front-rear direction so as to be arranged side by side with the first bottom beam 110.

[0046] The following description will be given assuming that the upper right ceiling beam of the first lower modular unit 200 is defined as the first ceiling beam 210, and the upper left ceiling beam of the second lower modular unit 400 is defined as the second ceiling beam 410. In Fig. 2, the first ceiling beam 210 is disposed below the first bottom beam 110 and extends in the front-to-back direction. In addition, the second ceiling beam 410 is disposed below the second bottom beam 310 and extends in the front-to-back direction.

[0047] Accordingly, the first bottom beam 110 and the second bottom beam 310 are arranged side by side in the left-right direction, and below the first bottom beam 110 and the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410 are arranged side by side in the left-right direction.

[0048] A modular unit connection device 1 according to one embodiment of the present invention fastens the first bottom beam 110 of the first upper modular unit 100, the second bottom beam 310 of the second upper modular unit 300, the first ceiling beam 210 of the first lower modular unit 200, and the second ceiling beam 410 of the second lower modular unit 400.

[0049] As a result, by integrating the first bottom beam 110, the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410, sagging and vibration of the first bottom beam 110, the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410 can be suppressed, and the resistance performance against lateral forces and vertical loads can be improved, thereby reducing the standards of the first bottom beam 110, the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410.

[0050] To this end, as shown in FIG. 3, a modular unit connection device 1 according to one embodiment of the present invention includes a main plate 10, a first sub-plate 20, a second sub-plate 30, a first main fixing member 41, a second main fixing member 42, a third main fixing member 43, a first sub-fixing member 51, a second sub-fixing member 52, a cover 60, a first support 70 and a second support 80.

[0051] The main plate 10 is formed in a plate shape. However, there is no limitation to the shape of the plate-like main plate 10. In this embodiment, the main plate 10 is described as being formed in a square plate shape.

[0052] 3, one surface 10a of the main plate is disposed toward the right side of the first bottom beam 110, and the other surface 10b of the main plate is disposed toward the left side of the second bottom beam 310. That is, the main plate 10 is disposed between the first bottom beam 110 and the second bottom beam 310, which are disposed at a predetermined interval.

[0053] There is no limitation on the front-rear width of the main plate 10. It is preferable that the front-rear width of the main plate 10 is smaller than the front-rear extension length of the first bottom beam 110 and the second bottom beam 310. Accordingly, a plurality of main plates 10 may be installed on the first bottom beam 110 and the second bottom beam 310.

[0054] A plurality of main plates 10 may be installed on the first bottom beam 110 and the second bottom beam 310 at a predetermined interval along the extension direction of the first bottom beam 110 and the second bottom beam 310. In this case, the plurality of main plates 10 may firmly fix the first bottom beam 110, the first ceiling beam 210, the second bottom beam 310 and the second ceiling beam 410.

[0055] In addition, in one embodiment of the present invention, the first floor beam 110, the first ceiling beam 210, the second floor beam 310 and the second ceiling beam 410 are extended to a length of 10 m or more and 15 m or less. Accordingly, the first floor beam 110, the first ceiling beam 210, the second floor beam 310 and the second ceiling beam 410 may sag due to their own weight and vertical load, or may vibrate due to external impact, but the multiple main plates 10 integrate the first floor beam 110 and the second floor beam 310, thereby reducing the sagging and vibration.

[0056] At this time, in order to connect the main plate 10 and the first bottom beam 110, the main plate 10 is provided with a first main wing 11. As shown in FIG. 3, the first main wing 11 protrudes from one surface 10a of the main plate and is fixed to the first bottom beam 110.

[0057] Accordingly, the main plate 10 is connected to the first beam 110 through the first main wing 11. A first base region 111a is formed on the upper surface of the first beam 110. The first main wing 11 is fixed to the first beam 110 through the first base region 111a. At this time, the name of the first base region 111a means one region located on the upper surface of the first beam 110.

[0058] The first bottom region 111a may be formed in a plurality of pieces. That is, when a plurality of main plates 10 are provided, a plurality of first main wings 11 protruding from the main plate 10 are also provided, so that a plurality of first main wings 11 can be coupled to each of the plurality of first bottom regions 111a.

[0059] 3, a first main wing 11 has a first main wing hole 12. At this time, although not shown in FIG 3, a hole may be formed in a first bottom area 111a of the first bottom beam 110 at a position corresponding to the first main wing hole 12. In this case, the first main wing 11 can be coupled to the first bottom beam 110 by coupling the hole in the first bottom area 111a to the first main wing hole 12 through a first main fixing member 41 described below.

[0060] However, when the first main wing 11 is directly connected to the first bottom beam 110 as described above, there is a problem that the first main wing 11 and the first main fixing member 41 may protrude and be exposed from the bottom of the first upper modular unit 100.

[0061] To prevent this, a first support 70 may be disposed between the first main wing 11 and the first bottom beam 110. That is, as shown in Fig. 3, the lower surface 70b of the first support 70 contacts the first bottom region 111a, and the upper surface 70a of the first support contacts the lower surface of the first main wing 11.

[0062] The first support 70 not only mediates the connection between the first main wing 11 and the first bottom beam 110, but also provides a space that prevents the first main wing 11 from protruding outward by being combined with a stopper 500 that acts as a concrete mold.

[0063] For this purpose, the first support 70 is formed such that an upper surface 70a of the first support corresponds to the first main wing 11. In this case, the first support 70 includes a first side wall 71 that protrudes upward along an edge of the upper surface 70a of the first support.

[0064] At this time, the first side wall 71 is open toward the main plate 10. That is, when the upper surface 70a of the first support 70 is formed in a rectangular shape, the first side wall 71 is formed in a “⊂” shape when viewed from above the first support 70.

[0065] The first side wall 71 is connected to the stopper 500. The first side wall 71 and the stopper 500 may be integrally formed, or the first side wall 71 and the stopper 500 may be welded and joined on-site. Accordingly, the first side wall 71, together with the stopper 500, serves to prevent the flow of poured concrete.

[0066] 3, a first space 72 is formed between an upper surface 70a of the first support and a lower surface 70b of the first support. The first space 72 provides a space in which a lower end of the first main fixing member 41 coupled to the first main wing hole 12 can be positioned.

[0067] The first support wall 74 connects a plate including the upper surface 70a of the first support to a plate including the lower surface 70b of the first support. At this time, the first support wall 74 is formed to be open in a direction perpendicular to the main plate 10 as shown in Fig. 3. More specifically, the first support wall 74 is formed parallel to the main plate 10.

[0068] The first support wall 74 is connected to the stopper 500. The first support wall 74 and the stopper 500 may be integrally formed, or the first support wall 74 and the stopper 500 may be welded and connected on-site. Accordingly, the first support wall 74, together with the stopper 500, serves to prevent the flow of concrete being poured.

[0069] Concrete to be poured can flow into the open side of the first support wall 74. That is, the first support wall 74, together with the first side wall 71 and the stopper 500, serves to prevent the concrete 600 from flowing.

[0070] 3, a first support hole 73 is formed in the first support 70 at a position corresponding to the first main wing hole 12 formed in the first main wing 11. The first support hole 73 is formed penetrating from the upper surface 70a of the first support to the first space 72.

[0071] At this time, the first main wing 11 is fixed to the first support 70 by the first main fixing member 41 which is simultaneously inserted into the first main wing hole 12 and the first support hole 73. The first main fixing member 41 may be any of various known parts. In this embodiment, it is described as being a bolt and a nut. Accordingly, the bolt of the first main fixing member 41 is inserted upward through the first support hole 73 and passes through the first main wing hole 12. At this time, the nut of the first main fixing member 41 is fastened to fasten the first main wing 11 to the first support 70.

[0072] Meanwhile, a first sub-plate 20 is coupled to the main plate 10 in order to fix the main plate 10 and a first ceiling beam 210. The first sub-plate 20 is provided with a first sub-wing 21 coupled to the first ceiling beam 210.

[0073] The first sub-wing 21 protrudes from the first sub-plate 20. The first sub-wing 21 may be formed integrally with the first sub-plate 20. The first sub-wing 21 and the first sub-plate 20 may be formed so that the cross section perpendicular to the front-to-rear direction has a "┐" shape.

[0074] At this time, a first ceiling area 212a is formed on the lower surface of the first ceiling beam 210. The first sub-wing 21 is fixed to the first ceiling beam 210 through the first ceiling area 212a. At this time, the name of the first ceiling area 212a means an area located on the upper surface of the first ceiling beam 210.

[0075] The first ceiling region 212a may be formed in a plurality of pieces. That is, when a plurality of main plates 10 are provided, a plurality of first sub-plates 20 coupled to the main plates 10 are also provided. Accordingly, a plurality of first sub-wings 21 protruding from the first sub-plates 20 are also provided, so that a plurality of first sub-wings 21 can be coupled to each of the plurality of first ceiling regions 212a.

[0076] The first sub-wing 21 is fixed to the first ceiling beam 210 through the first ceiling region 212a. One surface, i.e., the upper surface, of the first sub-wing 21 contacts the first ceiling region 212a formed on the lower surface of the first ceiling beam 210. The first ceiling region 212a may be formed in a plurality of portions corresponding to the number of the first sub-wings 21 provided.

[0077] As shown in Fig. 3, a first sub-wing hole 22 is formed in the first sub-wing 21. At this time, as shown in Fig. 3, a first ceiling beam hole 213 is formed in a first ceiling region 212a of a first ceiling beam 210 at a position corresponding to the first sub-wing hole 22.

[0078] The first sub-fixing member 51 is inserted into the first ceiling beam hole 213 and the first sub-wing hole 22 to connect the first sub-wing 21 and the first ceiling beam 210. Known parts may be used for the first sub-fixing member 51. In this embodiment, it will be described as being a bolt and nut like the first main fixing member 41.

[0079] An upper end of the first sub-fixing member 51 passes through a first ceiling beam hole 213 of the first ceiling beam 210 and is disposed inside the first ceiling beam 210. Conversely, a lower end of the first sub-fixing member 51 passes through a first sub-wing hole 22 and is exposed to the outside. However, the exposed first sub-fixing member 51 is blocked by a ceiling material 91 described below.

[0080] On the other hand, the first sub-plate 20 is formed in a plate shape. Accordingly, one surface of the first sub-plate 20 contacts one surface of the left side of the main plate 10.

[0081] At this time, in order to fix the main plate 10 and the first sub-plate 20, a main plate hole 15 is formed in the main plate 10, and a first sub-plate hole 23 is formed in the first sub-plate 20 at a position corresponding to the main plate hole 15.

[0082] Accordingly, as shown in FIG. 3, the third main fixing member 43 is inserted into the main plate hole 15 and the first sub-plate hole 23 to couple the main plate 10 and the first sub-plate 20 together.

[0083] At this time, various known parts may be used for the third main fixing member 43, as well as the first main fixing member 41 and the first sub fixing member 51. In this embodiment, the third main fixing member 43 will be described as being a bolt and nut. By using known bolts and nuts for the third main fixing member 43, the first main fixing member 41 and the first sub fixing member 51, the user can easily fix the main plate 10, the first sub plate 20, the first main wing 11 and the first sub wing 21.

[0084] The third main fixing member 43 not only fixes the first sub-plate 20 and the main plate 10 together, but also fixes the second sub-plate 30 (described later) to the main plate 10 together with the first sub-plate 20 .

[0085] That is, the third main fixing member 43 fixes the first sub-plate 20 to one surface on the left side of the main plate 10, and fixes the second sub-plate 30 to the other surface on the right side of the main plate 10.

[0086] More specifically, as shown in FIG. 3, the third main fixing member 43 is not only inserted into the main plate hole 15 and the first sub-plate hole 23, but also into the second sub-plate hole 33 described below, thereby fixing the main plate 10, the first sub-plate 20 and the second sub-plate 30.

[0087] Meanwhile, the modular unit connection device 1 according to one embodiment of the present invention can not only connect the first bottom beam 110 of the first upper modular unit 100 and the first ceiling beam 210 of the first lower modular unit 200, but can also simultaneously connect the second bottom beam 310 of the second upper modular unit 300 and the second ceiling beam 410 of the second lower modular unit 400.

[0088] For this purpose, the modular unit connection device 1 according to one embodiment of the present invention further includes a second main wing 13, a second sub-plate 30 and a second sub-wing 31 to additionally connect the second bottom beam 310 of the second upper modular unit 300 and the second ceiling beam 410 of the second lower modular unit 400.

[0089] In this case, the second main wing 13, the second sub-plate 30 and the second sub-wing 31 are formed or positioned in the opposite positions to the first main wing 11, the first sub-plate 20 and the first sub-wing 21, but have the same shape.

[0090] Therefore, the descriptions of the second main blade 13, the second sub-plate 30, the second sub-blade 31 and the second main blade holes 14, the second sub-plate holes 33, and the second sub-blade holes 32 provided thereon are replaced with descriptions of the first main blade 11, the first sub-plate 20, the first sub-blade 21 and the first main blade holes 12, the first sub-plate holes 23, and the first sub-blade holes 22 provided thereon, respectively.

[0091] Also, the description of the second main fixing member 42 and the second sub fixing member 52 will be substituted with the description of the first main fixing member 41 and the first sub fixing member 51.

[0092] In addition, the second support 80 provided for connecting the second main wing 13 to the second bottom beam 310 differs from the first support 70 only in the position and direction in which it is arranged, so the description of the second support 80 and the second side wall 81 and second support wall 84 provided thereon is replaced with the description of the first support 70 and the first side wall 71 and first support wall 74 provided thereon.

[0093] Meanwhile, there is no limitation on the type of the first bottom beam 110, the first ceiling beam 210, the second bottom beam 310 and the second ceiling beam 410 to which the modular unit connection device 1 according to an embodiment of the present invention can be connected. For example, the first bottom beam 110, the first ceiling beam 210, the second bottom beam 310 and the second ceiling beam 410 can be an "H" shaped beam as shown in Fig. 3, a "⊂" shaped beam as shown in Fig. 4, or a square beam as shown in Fig. 5. Also, as shown in Fig. 4, the first bottom beam 110 and the second bottom beam 310 can be a "⊂" shaped beam, and the first ceiling beam 210 and the second ceiling beam 410 can also be an "H" shaped beam.

[0094] In other words, the modular unit connection device 1 according to one embodiment of the present invention has the advantage that it can be connected to the first bottom beam 110, the first ceiling beam 210, the second bottom beam 310 and the second ceiling beam 410 which are made of various types of beams available in the market.

[0095] However, as shown in FIG. 5, when the first ceiling beam 210 and the second ceiling beam 410 are rectangular beams, the first sub-fixing member 51 and the second sub-fixing member 52 are joined to the first ceiling beam 210 and the second ceiling beam 410, respectively, by a known method such as welding.

[0096] Meanwhile, the modular unit connection device 1 according to an embodiment of the present invention further includes a cover 60. As shown in Fig. 3, the cover 60 is disposed inside a first side wall 71 of the first support 70 and a second side wall 81 of the second support 80.

[0097] The cover 60 covers the upper surface 70a of the first support and the upper surface 80a of the second support. At this time, the cover 60 covers the upper end of the first main fixing member 41 disposed by being inserted through the first support hole 73 formed in the upper surface 70a of the first support and the upper end of the second main fixing member 42 disposed by being inserted through the second support hole 83 formed in the upper surface 80a of the second support.

[0098] For this purpose, the cover 60 is formed so that the lower surface thereof is recessed upward. That is, the upper end of the first main fixing member 41 and the upper end of the second main fixing member 42 are disposed inside the recess of the cover 60.

[0099] The height of the edge wall of the recessed portion of the cover 60 is formed to be the same as the height of the first side wall 71 and the second side wall 81. Accordingly, when the cover 60 is placed within the first side wall 71 and the second side wall 81, the height of the upper ends of the first side wall 71 and the second side wall 81 is the same as the height of the upper surface of the cover 60, so that bending can be prevented in the process of covering the poured concrete 600 with the base material 92 described later.

[0100] Hereinafter, a process of connecting the first floor beam 110, the first ceiling beam 210, the second floor beam 310 and the second ceiling beam 410 using the modular unit connecting device 1 according to an embodiment of the present invention will be described with reference to FIGS.

[0101] 6, the first lower modular unit 200 and the second lower modular unit 400 are arranged side by side. Accordingly, the first ceiling beam 210 of the first lower modular unit 200 and the second ceiling beam 410 of the second lower modular unit 400 are arranged side by side in the front-rear direction.

[0102] At this time, the first lower modular unit 200 and the second lower modular unit 400 are disposed at a distance from each other so that the main plate 10 is disposed between the first ceiling beam 210 of the first lower modular unit 200 and the second ceiling beam 410 of the second lower modular unit 400.

[0103] 7, the first upper modular unit 100 and the second upper modular unit 300 are stacked on the upper sides of the first lower modular unit 200 and the second lower modular unit 400. At this time, the first bottom beam 110 of the first upper modular unit 100 and the second bottom beam 310 of the second upper modular unit 300 are arranged side by side in the front-rear direction.

[0104] Meanwhile, a core member 93 for securing a space may be disposed between the first upper modular unit 100 and the first lower modular unit 200. The core member 93 serves to adjust the gap between the first upper modular unit 100 and the first lower modular unit 200 and between the second upper modular unit 300 and the second lower modular unit 400, and to adjust the height of the bottom of the first upper modular unit 100 and the bottom of the second upper modular unit 300.

[0105] 3 and 8, the main plate 10 is inserted between the stacked first upper modular unit 100 and second upper modular unit 300. At this time, the first main wing 11 is disposed inside the first side wall 71 of the first support 70, and the second main wing 13 is disposed inside the second side wall 81 of the second support 80.

[0106] The first main wing 11 and the first support 70 are connected through the first main fixing member 41 and the second main fixing member 42, and the second main wing 13 and the second support 80 are connected through the first main fixing member 41 and the second main fixing member 42.

[0107] Meanwhile, before the first main wing 11 and the second main wing 13 are combined, the first upper modular unit 100 has a first support 70 fixed to the first bottom region 111a of the first bottom beam 110, and the second upper modular unit 300 has a second support 80 fixed to the second bottom region 311a of the second bottom beam 310.

[0108] In addition, concrete 600 is placed at the bottom of the first upper modular unit 100 and the second upper modular unit 300, with the stopper 500, the first support 70, and the second support 80 closed. At this time, the concrete 600 is poured while the bolts of the first main fixing member 41 and the second main fixing member 42 before pouring the concrete 600 are inserted into the first support hole 73 and the second support hole 83, respectively.

[0109] As shown in Figures 3 and 9, with the first main wing 11 and the second main wing 13 joined together, the first sub-plate 20 and the second sub-plate 30 are joined to both sides of the main plate 10.

[0110] In addition, the first sub-wing 21 and the second sub-wing 31 are connected to the first ceiling beam 210 of the first lower modular unit 200 and the second ceiling beam 410 of the second lower modular unit 400 through the first sub-fixing member 51 and the second sub-fixing member 52.

[0111] As a result, the first bottom beam 110, the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410 are connected through the first main wing 11, the second main wing 13, the first sub-wing 21 and the second sub-wing 31, thereby firmly connecting the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400.

[0112] Meanwhile, as shown in Figures 3 and 10, after the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400 are combined, a cover 60 is placed inside the first side wall 71 of the first support 70 and the second side wall 81 of the second support 80.

[0113] The cover 60 covers the upper ends of the first main fixing member 41 and the second main fixing member 42. Accordingly, the height of the bottoms of the first upper modular unit 100 and the second upper modular unit 300 and the height of the cover 60 become the same.

[0114] 3 and 11, with the cover 60 in place, the base material 92 is stacked on the bottoms of the first upper modular unit 100 and the second upper modular unit 300 to complete the installation of the modular unit connecting device 1. At this time, the base material 92 can be stacked on the bottoms of the first upper modular unit 100 and the second upper modular unit 300 without bending due to the cover 60.

[0115] Hereinafter, a modular unit connecting device 1 according to another embodiment of the present invention will be described with reference to FIGS.

[0117] 12, the modular unit combination device 1 according to another embodiment of the present invention is different from the modular unit combination device 1 according to the above-mentioned embodiment in the installation direction, and each component is the same. Therefore, the following description will focus on the difference in the installation direction, and the shape and function of each component are substituted by the above-mentioned content.

[0118] As shown in FIG. 12, the first main wing 11 of the modular unit connection device 1 according to another embodiment of the present invention is fixed to the third ceiling area 211a of the first ceiling beam 210 of the first lower modular unit 200, and the second main wing 13 is fixed to the fourth ceiling area 411a of the second ceiling beam 410 of the second lower modular unit 400.

[0119] At this time, the third ceiling area 211a is formed on the upper surface of the first ceiling beam 210, and the fourth ceiling area 411a is formed on the upper surface of the second ceiling beam 410. A third ceiling beam hole 214 is formed in the third ceiling area 211a, and a fourth ceiling beam hole 414 is formed in the fourth ceiling area 411a.

[0120] The first main wing 11 is fixed to the first ceiling beam 210 by a first main fixing member 41 inserted into the first main wing hole 12 and the third ceiling beam hole 214. The second main wing 13 is fixed to the second ceiling beam 410 by a second main fixing member 42 inserted into the second main wing hole 14 and the fourth ceiling beam hole 414.

[0121] As shown in FIG. 12, the core member 93 is disposed between the first bottom beam 110 and the first ceiling beam 210 to support the underside of the first bottom beam 110 and the upper surface 211 of the first ceiling beam, and is disposed between the second bottom beam 310 and the second ceiling beam 410 to support the underside of the second bottom beam 310 and the upper surface 411 of the second ceiling beam.

[0122] Multiple core members 93 may be arranged, and there are no restrictions on the locations where they can be arranged as long as they can provide support between the first bottom beam 110 and the first ceiling beam 210, and between the second bottom beam 310 and the second ceiling beam 410.

[0123] By positioning the core member 93, not only can the height between the first ceiling beam 210 and the first bottom beam 110 and the height between the second ceiling beam 410 and the second bottom beam 310 be adjusted, but also space can be provided in which the upper ends of the first main fixing member 41 and the second main fixing member 42 and the first main wing 11 and the second main wing 13 can be positioned.

[0124] 12, the first support 70 is disposed in the first bottom region 111a of the first bottom beam 110. The first support 70 is coupled to the first bottom beam 110 with the lower surface of the first support 70 in contact with the first bottom region 111a. At this time, there is no limitation on the method of coupling the first support 70.

[0125] The second support 80 is also disposed in the second bottom region 311a of the second bottom beam 310, similar to the first support 70. The second support 80 is coupled to the second bottom beam 310 with the lower surface of the second support 80 in contact with the second bottom region 311a.

[0126] The first sub-wing 21 is fixed to the first support 70, and the second sub-wing 31 is fixed to the second support 80. That is, as shown in FIG. 12, the first support 70 is disposed between the first sub-wing 21 and the first bottom beam 110, and the second support 80 is disposed between the second sub-wing 31 and the second bottom beam 310.

[0127] The first sub-fixing member 51 is inserted and fixed into a first support hole 73 formed in the first support 70 and a first sub-wing hole 22 formed in the first sub-wing 21. The second sub-fixing member 52 is inserted and fixed into a second support hole 83 formed in the second support 80 and a second sub-wing hole 32 formed in the second sub-wing 31.

[0128] Hereinafter, a process of connecting the first floor beam 110, the first ceiling beam 210, the second floor beam 310 and the second ceiling beam 410 using the modular unit connecting device 1 according to another embodiment of the present invention will be described with reference to FIGS.

[0129] 12 and 13, the first lower modular unit 200 and the second lower modular unit 400 are arranged side by side. Accordingly, the first ceiling beam 210 of the first lower modular unit 200 and the second ceiling beam 410 of the second lower modular unit 400 are arranged side by side in the front-rear direction.

[0130] At this time, the first lower modular unit 200 and the second lower modular unit 400 are disposed at a distance from each other so that the main plate 10 is disposed between the first ceiling beam 210 of the first lower modular unit 200 and the second ceiling beam 410 of the second lower modular unit 400.

[0131] 14, the first main wing 11 and the second main wing 13 are disposed in the third ceiling area 211a of the first ceiling beam 210 and the fourth ceiling area 411a of the second ceiling beam 410, respectively. At this time, the first main wing hole 12 formed in the first main wing 11 and the third ceiling beam hole 214 formed in the first ceiling beam 210 are fixed by the first main fixing member 41. In addition, the second main wing hole 14 formed in the second main wing 13 and the fourth ceiling beam hole 414 formed in the second ceiling beam 410 are fixed by the second main fixing member 42.

[0132] In this case, as shown in Figures 12 and 14, unlike the modular unit connection device 1 according to one embodiment of the present invention described above, the main plate 10 is positioned above the first main wing 11 and the second main wing 13.

[0133] 12 and 15, the first upper modular unit 100 and the second upper modular unit 300 are stacked on the upper sides of the first lower modular unit 200 and the second lower modular unit 400. At this time, the first bottom beam 110 of the first upper modular unit 100 and the second bottom beam 310 of the second upper modular unit 300 are arranged side by side in the front-rear direction.

[0134] A core member 93 for securing a space is disposed between the first upper modular unit 100 and the first lower modular unit 200. The core member 93 provides a space between the first upper modular unit 100 and the first lower modular unit 200 and between the second upper modular unit 300 and the second lower modular unit 400, and provides a space in which the first main wing 11 and the second main wing 13 are positioned.

[0135] 12 and 15, the main plate 10 is positioned between the stacked first upper modular unit 100 and second upper modular unit 300. At this time, the first sub-wing 21 is disposed inside the first side wall 71 of the first support 70, and the second sub-wing 31 is disposed inside the second side wall 81 of the second support 80.

[0136] The first sub-wing 21 and the first support 70 are connected through the first sub-fixing member 51 and the second sub-fixing member 52, and the second sub-wing 31 and the second support 80 are connected.

[0137] Meanwhile, before the first sub-wing 21 and the second sub-wing 31 are combined, the first upper modular unit 100 has a first support 70 fixed to the first bottom region 111a of the first bottom beam 110, and the second upper modular unit 300 has a second support 80 fixed to the second bottom region 311a of the second bottom beam 310.

[0138] In addition, concrete 600 is placed at the bottom of the first upper modular unit 100 and the second upper modular unit 300, with the stopper 500, the first support 70, and the second support 80 closed. At this time, the concrete 600 is poured while the bolts of the first sub-fixing member 51 and the second sub-fixing member 52 before pouring the concrete 600 are inserted into the first support hole 73 and the second support hole 83, respectively.

[0139] As shown in Figures 12 and 16, with the first main wing 11 and the second main wing 13 joined together, the first sub-plate 20 and the second sub-plate 30 are joined to both sides of the main plate 10.

[0140] In addition, the first sub-wing 21 and the second sub-wing 31 are connected to the first base beam 110 of the first upper modular unit 100 and the second base beam 310 of the second upper modular unit 300 through the first sub-fixing member 51 and the second sub-fixing member 52.

[0141] As a result, the first bottom beam 110, the second bottom beam 310, the first ceiling beam 210 and the second ceiling beam 410 are connected through the first main wing 11, the second main wing 13, the first sub-wing 21 and the second sub-wing 31, thereby firmly connecting the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400.

[0142] Meanwhile, as shown in Figures 12 and 17, after the first upper modular unit 100, the second upper modular unit 300, the first lower modular unit 200 and the second lower modular unit 400 are combined, a cover 60 is placed inside the first side wall 71 of the first support 70 and the second side wall 81 of the second support 80.

[0143] The cover 60 covers the upper ends of the first sub-fixing member 51 and the second sub-fixing member 52. Accordingly, the height of the bottoms of the first upper modular unit 100 and the second upper modular unit 300 and the height of the cover 60 become the same.

[0144] 18, with the cover 60 in place, the base material 92 is stacked on the bottoms of the first upper modular unit 100 and the second upper modular unit 300 to complete the installation of the modular unit connecting device 1. At this time, the base material 92 can be stacked on the bottoms of the first upper modular unit 100 and the second upper modular unit 300 without bending due to the cover 60.

[0145] Fig. 19 is a cross-sectional view of a modular unit combination device according to another embodiment of the present invention, which is a cross-sectional view of a modular unit combination device combined with one modified example of a first upper modular unit, a second upper modular unit, a first lower modular unit, and a second lower modular unit. Fig. 20 is a cross-sectional view of a modular unit combination device according to another embodiment of the present invention, which is a cross-sectional view of a modular unit combination device combined with another modified example of a first upper modular unit, a second upper modular unit, a first lower modular unit, and a second lower modular unit.

[0146] As shown in Figures 19 and 20, there are no limitations on the types of first bottom beam 110, first ceiling beam 210, second bottom beam 310 and second ceiling beam 410 to which the modular unit connection device 1 according to another embodiment of the present invention can be connected.

[0147] For example, the first floor beam 110, the first ceiling beam 210, the second floor beam 310 and the second ceiling beam 410 may be "H" shaped beams as shown in Fig. 18, may be "⊂" shaped beams as shown in Fig. 19, or may be square beams as shown in Fig. 20. Also, as shown in Fig. 19, the first ceiling beam 210 and the second ceiling beam 410 may be "⊂" shaped beams, and the first floor beam 110 and the second floor beam 310 may be "H" shaped beams.

[0148] However, as shown in FIG. 20, when the first ceiling beam 210 and the second ceiling beam 410 are rectangular beams, the first main fixing member 41 and the second main fixing member 42 are joined to the first ceiling beam 210 and the second ceiling beam 410, respectively, by a known method such as welding.

[0149] As described above, the preferred embodiments of the present invention have been described in detail, and it will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the present invention.
