As shown in FIG. 2, the basic skeleton of the modules 10, 20 is identical to the modules of the prior art. That is, the module 10, 20 is composed of a beam member provided in the upper, lower, and the column 50 connecting the edge of the beam member.

By the way, in the prior art, as described above, when constructing the layer structure (1), the upper and lower members are combined, each occupying a space, so that the higher the layer structure (1), the higher the height of the layer structure. .

However, in the joining structure of the floor height-reducing modular building according to the present invention, by combining the coupling member 30, 40 corresponding to the upper and lower members of the prior art module so as not to occupy space, respectively, so as to overlap each other, It is to lower the height of the layer structure (1).

That is, the modular system according to the present invention is provided to the plurality of unit modules (10) 20 and the modules (10) 20 in combination to provide a layer structure (1), of the layer structure (1) In order to reduce the height of the floor, it is configured to include a coupling member 30, 40 overlapping the construction.

2, the lower coupling member 30 of the upper module 10 and the upper coupling member 40 of the lower module 20 are configured to overlap each other.

As the overlapping configuration of the coupling members 30 and 40 is repeated for each layer, the height of the layer structure 1 is significantly lower than that of the conventional modular system.

3 and 4, the coupling members 30 and 40 of the modules 10 and 20 according to the present invention are the first members 32 and 42 and the second member 34. ), And the second members 34 and 44 overlap.

That is, the lower coupling member 30 of the upper layer module 10 and the upper coupling member 40 of the lower layer module 20 are composed of first members 32, 42 and second members 34, 44, respectively. have. Then, by overlapping the second members 34 and 44 of the respective coupling members 30 and 40, the coupling members 30 and 40 are coupled.

3 and 4, each coupling member 30, 40, the first member 32, 42 is horizontal, the second member 34, 44 is the first member ( 32, 42 is vertically coupled, the second member 34, 44 is a structure coupled to both sides of the first member (32, 42).

Each coupling member 30 and 40 has a hollow rectangular column shape in which one side of the cross section is open, and the lower coupling member 30 of the upper layer module 10 has an open side facing downward and the lower layer module 20. The upper coupling member 40 of the open one side is directed upward. That is, each coupling member 30, 40 is in the 'c' shape.

In addition, the lower coupling member 30 of the upper layer module 10 and the upper coupling member 40 of the lower layer module 20 overlap with each other when the layer structure 1 is installed, and the open one surface thereof faces each other.

At this time, the coupling member 40 of the lower module 20 is inserted into the open one surface of the coupling member 30 of the upper module 10 is overlapped. That is, the coupling member 30 of the upper module 10 is configured to receive at least a portion of the coupling member 40 of the lower module 20.

In addition, the inner surface of the second member 34 of the upper module 10 coupling member 30 and the outer surface of the second member 44 of the lower module 20 coupling member 40 are configured to overlap each other, It is preferable that the coupling of the coupling members 30 and 40 is made firm.

In addition, the overlapping state of the coupling members 30 and 40 becomes a hollow rectangular pillar. However, in this case, as shown in FIGS. 3 and 4, the second members 34 and 44 in an overlapping state are thicker than the first members 32 and 42. That is, since the upper, lower and left and right members have different thicknesses in the drawing, stiffness with respect to the load may be reduced, thereby removing the first members 32 and 42 of the coupling member 30 and 40. It is preferable to form thicker than the two members 34 and 44.

Here, in FIGS. 3 and 4, the first members 32 and 42 of the coupling members 30 and 40 are horizontally illustrated, and the second members 34 and 44 are illustrated vertically, but embodiments of the present disclosure are not limited thereto. In accordance with the concept of the present invention, various types of coupling members 30 and 40 may overlap each other.

In addition, the shape of the coupling member 30 of the upper module 10 and the coupling member 40 of the lower module 20 may be formed in the reverse direction.

In addition, since the modular system is preferably manufactured to the same size in order to shorten the construction period of the layer structure (1) and at the same time to easily build the layer structure (1), the pillars 50 of the modules 10, 20 It is formed to the same thickness. In this way, when the column 50 is manufactured in the same standard, the load supporting effect is excellent.

Therefore, the coupling member 30 of the upper module 10 is preferably formed to a size large enough to accommodate at least the upper end of the column 50 of the lower module 20. 3 and 4, the width of the coupling member 30 of the upper module 10 is configured to be formed thicker than the width of the column 50, the inner edge of the coupling member 30 of the upper module 10 The upper end of the pillar 50 of the lower layer module 20 is inserted.

Of course, the coupling members 30 and 40 are not necessarily limited to the above shapes in order to manufacture the pillars 50 of the respective modules 10 and 20 to the same standard, and various forms are possible.

For example, although not shown, the edge portion of the coupling member of the upper module may be formed to be removed (omitted). At this time, even if the width of the coupling member of the upper module is the same or smaller than the pillar does not interfere with each other, there is no problem in coupling the module. However, in this case, since the coupling portion of the pillar and the coupling member of the upper module may be weak, it is preferable to install a reinforcing member on the coupling portion to reinforce the coupling force.

Next, the coupling member 30, 40 of the present invention is characterized in that it comprises a coupling means 60 is provided in the form steel, the coupling member 30 is provided to engage the overlapping portion 30, 40.

Referring to FIG. 5, the overlapping portions of the second members 34 and 44 of the coupling members 30 and 40 are coupled by the bolt 62 and the nut 64, which are the coupling means 60.

That is, a plurality of first fastening holes 36 are formed on the side surfaces of the coupling member 30 of the upper layer module 10, and the first fastening holes are also provided on the side surfaces of the coupling member 40 of the lower layer module 20. A plurality of second fastening holes 46 drilled to correspond to 36 are provided.

Then, after the second members 34 and 44 overlap each other, the bolt 62 is inserted into the first fastener 36 and the second fastener 46, and the coupling member 30 is tightened by tightening the nut 64. 40 is combined.

As such, the bolt 62 and the nut 64 are provided at regular intervals on the side surfaces in the lengthwise direction of the coupling members 30 and 40, so that the bolt 62 and the nut 64 at each fastener with respect to the load. Becomes resistant, and the overall rigidity against load is improved. Accordingly, there is an effect that can increase the length (span) of the coupling member 30, 40 more.

Here, the nut 64 may be provided separately, but since the construction of the nut 64 is difficult to fix the position of the nut 64 after the second members 34 and 44 overlap, the coupling member of the lower layer module 20 is provided. It is preferable that the nut 64 fixed to the inner surface of the 40 is provided in advance.

In addition, as described later, the filling member 70 may be filled in a space in which the coupling members 30 and 40 overlap each other, thereby improving rigidity of the coupling members 30 and 40.

At this time, after filling the filling 70 in the space as described above to combine the coupling member 30, 40 with the bolt 62 and the nut 64. However, when the nut 64 is short, it may be difficult to insert and fasten the bolt 62 to the end by the hardened filler material 70. Therefore, the nut 64 is preferably formed to have a height such that the bolt 62 can be fastened to the end so as not to be affected by the filling 70.

In addition, the coupling means 60 is not limited to the bolt 62 and the nut 64, of course. That is, the second members 34 and 44 may be joined by welding and joining the overlapped portions.

Next, in the space formed by the coupling members 30 and 40 of the present invention overlapped by the vertical members, which are the first members 32 and 42, and the vertical members, which are the second members 34 and 44, the layer. To increase the rigidity of the structure (1), it is characterized in that the filler material 70 is filled.

When the upper layer module 10 and the lower layer module 20 are coupled to each other, a space may or may not be formed by the first member and the second member depending on the shape of the coupling members 30 and 40.

As shown in FIGS. 3 and 4, when spaces are formed by the first members 32 and 42 and the second members 34 and 44 when the coupling members 30 and 40 overlap each other. In the space, by filling the filling 70 such as concrete, it is possible to improve the rigidity of the coupling member (30, 40).

In addition, as described above, when the nut 64 is provided inside the coupling member 40 of the lower layer module 20, the nut 64 serves as a stud of the concrete-filled steel pipe to fill the filling 70 ) And the coupling member 30, 40 has an effect of improving the resistance to the load of the layer structure (1) by improving the bonding force.

Next, as described above, the coupling member may be variously formed as one embodiment only. That is, according to the concept of the present invention, if the coupling member of the upper layer module 10 and the coupling member of the lower layer module 20 are configured to overlap, other forms are possible.

6 shows another embodiment of the coupling members 80 and 90 according to the present invention in detail, and shows a cross-sectional view of the coupling members 80 and 90 in an overlapping state and an exploded view thereof.

Another embodiment of the coupling member 80 and 90 will be described in detail with reference to FIG. 6.

Each coupling member (80, 90) consists of a horizontal first member (82) (92) and the second member (84) (94) vertically coupled near the center of the first member (82, 92) have. The coupling member 80 of the upper module 10 is configured such that the second member 84 is formed downward, and the coupling member 90 of the lower module 20 is configured such that the second member 94 is formed upward. That is, the coupling member 80 of the upper module 10 has a cross section 'TT' shape, the coupling member 90 of the lower module 20 is formed in a 'ㅗ' shape.

In addition, the contact surface between the second members 84 and 94 is biased to one side with respect to the center of the first members 82 and 92, that is, the cross section of the state in which the coupling members 80 and 90 overlap with each other is left and right symmetrical. If it is not formed, there is a problem that the load does not act the same in the left and right, and the stability of the layer structure 1 is reduced.

Therefore, when the coupling members 80 and 90 overlap with each other in the second members 84 and 94, the contact surfaces of the second members 84 and 94 overlap with the first members 82 and 92. It is preferable to configure so as to coincide with the center of.

In addition, for the structural stability of the layered structure (1), the thickness of the first member (82, 92) is formed thicker than the thickness of the second member (84, 94) and the coupling means (60) Same as described.

In another embodiment of the coupling members 80 and 90, when the coupling members 80 and 90 overlap with each other, the first and second members 82 and 92 and the second and second members 84 and 94 are overlapped with each other. Since no space is formed, the filling cannot be filled.

In addition, various forms of the coupling member are possible as described above.

Although not shown, by applying another embodiment of the coupling member, the lower coupling member of the upper layer module has a second member is provided in the center of the first member, the upper coupling member of the lower module has two second members of the upper layer It may be configured to be provided in the first member with a space equal to the thickness of the second member of the coupling member of the module.

In this case, when the coupling member is coupled, the second member of the lower coupling member of the upper module overlaps with the second member of the upper coupling member of the lower module. In such a fitted form, the coupling members have a fixed position to some extent, such that the fastening by bolts and nuts is easy, and thus the workability is excellent.

In addition, in addition to changing the position and number of the second member of the coupling member according to the user's selection, of course, it is also possible to form a space for filling the filling by the first member and the second member. .
