Description

Connector for modular buildings and modular buildings including the same {MODULAR STRUCTURE CONNECTION APPARATUS AND MODULAR STRUCTURE HAVING THE SAME}

The present invention relates to a connecting device for modular buildings and a modular building including the same.

Modular buildings are constructed by stacking and assembling multiple unit modules. In such a modular building, the unit module is basically a column made of four or more steel materials arranged in a square shape (square, H-type, U-shaped) and a ceiling beam made of multiple steel materials connecting the upper parts of the plurality of columns (square, H-shaped). It is composed of a plurality of steel floor beams (square, H-type, C-shaped) connecting the lower parts of multiple columns.

Meanwhile, as major technologies related to modular buildings, technologies are being used to connect unit modules only at the pillars or join the beams adjacent to the pillars to minimize on-site construction.

Therefore, in the current unit module, ceiling beams only support finishing materials and construction loads and are used only to support ceiling finishing materials after completion, so their utilization rate as a structural member is not high. This results in an increase in the cross-sectional size of the floor beam supporting the floor load, which results in interference with mechanical/electrical equipment and an increase in the floor height of the entire building, making it uneconomical. In addition, transportation of unit modules is restricted due to height restrictions. It happens.

The cover member 331 is seated on the upper surface of two floor beams 220 adjacent to each other, as shown in FIGS. 5(a), 6(a), 7(a), and 8(a). Take structure. This cover member 331 may be formed with a cover hole 331a, which corresponds to the upper through hole 220a of each of the two floor beams 220 so that the fastening bolt 321 penetrates. is formed That is, each of the two floor beams 220 has an upper through hole 220a, and two cover holes 331a are formed in the cover member 331 to correspond to the two upper through holes 220a.

The cover member 331 formed in this way is pressed and fixed to the upper surface of the floor beam 220 by fastening the fastening bolt 321 to the nut member 312. The fastening bolt 321 penetrates the cover hole 331a of the cover member 331 before penetrating the upper through hole 220a of the floor beam 220 in order to be fastened to the lower nut member 312. At this time, the fastening bolt 321 is fastened. The head of the bolt 321 fails to pass through the cover hole 331a of the cover member 331 and is caught, thereby pressing the upper part of the cover member 331, causing the cover member 331 to be attached to the upper surface of the floor beam 220. It is fixed by pressure.

And, as shown in FIGS. 4(a), 6(a), and 8(a), the filler member 332 includes two floor beams 220 adjacent to each other and two connection boxes 311 adjacent to each other. ) takes the structure placed between. This pillar member 332 may be formed with a pillar hole 332a, which is formed to correspond to the box hole 311a so that the fastening bolt 321 passes through it. That is, each of the two connection boxes 311 has a box hole 311a, and two filler holes 332a are formed in the filler member 332 to correspond to the two box holes 311a.

The filler member 332 formed in this way is pressed and fixed between the floor beam 220 and the connection box 311 by fastening the fastening bolt 321 to the nut member 312. When the fastening bolt 321 is fastened to the nut member 312 fixed to the connection box 311, as the fastening bolt 321 presses the floor beam 220 downward, the filler member 332 presses the floor beam 220. It is pressed and fixed between and the connection box 311.

Meanwhile, Figures 5(b), 6(b), 7(b), and 8(b) are portions of the exterior of the modular building, where there are no unit modules to be connected in the lateral direction, which is the lateral direction of the modular building. In this case, the cover member 331 and the filler member 332 only have a size that is used in one unit module and do not have a size that is used across two unit modules. That is, the cover member 331 and the filler member 332 are used to horizontally connect the unit modules as shown in FIGS. 5(b), 6(b), 7(b), and 8(b). It may not be used. Of course, at this time, the cover member 331 and the filler member 332 can play a role in height adjustment, such as reducing and eliminating the gap in construction errors in terms of height, and play a role in distributing the load or preventing loosening like a washer. It can be done.

Meanwhile, the present invention can provide a modular building including the above-described connecting device 300.
