[0110] In other embodiments, the modular building can also be a double-column or three-column structure, that is, two or three columns are close to each other. The arrangement of multiple columns close to each other can increase the support strength.

[0111] When multiple upper columns 1 are close to each other and multiple lower columns 2 are close to each other, the connecting plates 531 of multiple connecting devices are fixedly connected or integrally formed. Among them, the upper columns 1 and the lower columns 2 are arranged one by one. The connecting devices and the upper columns 1 are arranged one by one.

[0112] The plurality of connection devices are connected to each other through a fixed connection or an integrally formed connection plate 531, thereby realizing the connection of the plurality of upper columns 1 and the plurality of lower columns 2, thereby increasing the strength of the entire modular building.

[0113] For example, Figure 5 A structural schematic diagram of two connecting components 53 with an integrally formed connecting plate 531 is shown, that is, the connecting plate 531 of the two connecting components 53 is integrally formed, two upper connecting parts 532 are provided on one side of the connecting plate 531, and two lower connecting parts 533 are provided on the other side, and the upper connecting parts 532 and the lower connecting parts 533 are arranged in a one-to-one correspondence.

[0114] The connecting assembly 53 of the above structure is used to connect two columns close to each other, such as Figure 6 At the same time, Figure 6 A partial structural schematic diagram of two upper columns, two lower columns and two temporary installation components is shown.

[0115] The connection device in this embodiment includes an upper partition, a lower partition, a connection assembly and a grouting piece. The upper partition is arranged in the upper column to separate an upper accommodating space, the lower partition is arranged in the lower column to separate a lower accommodating space, the upper connection piece of the connection assembly extends into the upper accommodating space, the lower connection piece extends into the lower accommodating space, the connection plate is located in the upper column and the lower column and separates the upper accommodating space from the lower accommodating space, the upper grouting piece is obtained by pouring slurry into the upper accommodating space and solidifying, the lower grouting piece is obtained by pouring slurry into the lower accommodating space and solidifying, the upper grouting piece connects the upper column, the upper connection piece and the connection plate, the lower grouting piece connects the lower column, the lower connection piece and the connection plate, thereby realizing the connection between the upper column and the lower column, thereby obtaining a column with a higher height. Compared with the connection box used for connection in the related art, the connection device realizes connection through the grouting piece with lower cost, saves the use of steel materials, saves the use of fireproof and anti-corrosion coatings, and thus reduces costs.

[0116] The modular building of the utility model adopts the above-mentioned connection device to achieve a high height and low cost. The modular building connected by the connection device can withstand pressure and bending moment and has strong tensile bearing capacity.

Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
