[0045] Another objective of this invention is to provide a modular building structure installation method to guide people in installing the new modular building structure, thereby improving the installation efficiency of the modular building structure.

[0046] Reference Figure 7 and Figure 10 A modular building structure installation method, based on the aforementioned modular building structure, includes the following steps: S1. The support plate 2 is installed at the lower position; S2. Arrange several layers of the modular unit 1 on the bearing plate 2; S3. After the modular unit 1 of several layers is installed, the structural column 3 is set at the mounting groove 14 of the modular unit 1, so that the lower end of the structural column 3 is connected to the bearing plate 2 below. S4. On the top of the modular unit 1, the bearing plate 2 is set, and the bearing plate 2 is connected to the upper end of the structural column 3. S5. Repeat steps S2 to S3 directly; Alternatively, steps S2 to S4 can be repeated directly; Alternatively, repeat steps S2 to S4 first, and then repeat steps S2 to S3. S6. Complete the installation of the modular building structure.

[0047] Reference Figure 7 and Figure 10 In one embodiment, a first support plate is first set at a predetermined location. After the first support plate is set, a first layer of modular units and a second layer of modular units are stacked on top of the first support plate. After the first and second layers of modular units are stacked, a first structural column 31 is installed at the mounting slots on the sides of the first and second layers of modular units, so that the lower end of the first structural column 31 is fixedly connected to the first support plate. Then, a second support plate is installed at the top of the second layer of modular units, so that the second support plate is fixedly connected to the upper end of the first structural column 31. Afterward, a third layer of modular units and a fourth layer of modular units are stacked on the second support plate. After the modular units are stacked, second structural columns 32 are installed in the mounting slots on the sides of the third and fourth layer modular units, with the lower ends of the second structural columns 32 fixedly connected to the second support plate. Then, the third support plate at the top of the fourth layer modular unit is installed, with the third support plate fixedly connected to the upper end of the second structural column 32. Next, a fifth and sixth layer modular unit are stacked on top of the third support plate. After the fifth and sixth layer modular units are stacked, third structural columns 33 are installed in the mounting slots on the sides of the fifth and sixth layer modular units, with the lower ends of the third structural columns 33 fixedly connected to the third support plate. This modular building structure of the present invention can reduce the pressure impact of upper modular units with a set floor height on lower modular units, ensure the versatility of the modular units, and facilitate the production of modular units.

[0048] In one embodiment, the modular building structure of the present invention has the following advantages: (1) Pressure dispersion and bottom protection: The modular unit with a set upper floor height applies pressure to the bearing plate 2, and the bearing plate 2 transmits the pressure to the structural column 3, instead of the modular unit with a set upper floor height directly applying pressure to the modular unit below; the load-bearing frame of the present invention, consisting of the bearing plate 2 and the structural column 3, can effectively prevent the bottom modular unit from being damaged due to excessive pressure.

[0049] (2) Modular unit has versatility: The mounting groove 14 on the modular unit 1 is a stepped mounting groove with a cross-section. The mounting groove 14 can meet the installation needs of the "first structural column 31, second structural column 32 and third structural column 33". The cross-sectional area of ​​the first structural column 31, second structural column 32 and third structural column 33 are designed differently. The higher the height, the smaller the cross-sectional area required for the structural column 3 can be to match the strength requirements of the structure at different floor heights. The modular unit 1 of the present invention does not need to be designed differently for different floor heights. Therefore, the present invention realizes the standardized design of the modular unit 1, which can facilitate the production of the modular unit 1 and improve the production efficiency of the modular unit 1.

[0050] (3) It helps to simplify the production process of modular units: This invention eliminates the need to design modular units of different strengths for multi-layer modular building structures, reducing the complexity of the modular unit production process and facilitating large-scale production of modular units.

[0051] (4) Modular buildings have excellent structural stability: After the structural column 3 is installed into the installation groove 14, the installation groove 14 can restrict the lateral movement of the structural column 3, making it difficult for the structural column 3 to fall out after being embedded in the installation groove 14, which greatly improves the overall shear resistance of the multi-layer modular single unit after stacking. (5) Stress optimization: When the second connecting hole B is designed as an oval through hole, the bolt fixes the structural column 3 to the side of the modular unit 1. When the structural column 3 is subjected to the pressure transmitted from the upper bearing plate, the structural column 3 is allowed to undergo "small" vertical displacement through the oval through hole. This is to avoid excessive stress at the connection between the bolt and the structural column at the second connecting hole B, which would cause the bolt to be sheared. It is also beneficial to avoid the structural column directly transmitting force to the side of the modular unit, effectively preventing the modular unit from being damaged due to excessive stress.

[0052] (6) Convenience of side-by-side installation of modular units: The protrusion 331 on the third structural column 33 has a third connecting hole D connected to the second connecting hole B. The vertical outer surface of the protrusion 331 is flush with the side surface of the modular unit 1. When multiple rows of modular units 1 are arranged side by side, bolts can be used to pass through the "first connecting hole 15, second connecting hole B and third connecting hole D" in the room of the modular unit 1 to connect the side-by-side modular units 1 together. This design of the present invention is beneficial to the connection of side-by-side modular units and is beneficial to improving the connection efficiency of side-by-side modular units.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
