Abstract: Disclosed herewith a modular integrated building and a construction method thereof. The building comprises multiple prefabricated room units (1). A bottom of a load-bearing structure of the prefabricated room unit (1) is provided with a semi-prefabricated connecting port (2). Reinforcing bars arranged at a top of the prefabricated room unit (1) of a next floor are inserted in the connecting port (2) and thus connected with reinforcing bars arranged therein, so that the prefabricated room units (1) of two adjacent floors are connected with each other through in-situ casting concrete in the connecting port (2). A cast-in-situ concrete interlayer (3) is arranged on a top plate (11) of the prefabricated room unit (1) of a next floor, for connecting adjacent prefabricated room units (1) of a same floor together.

Abstract: The present invention discloses an integrated steel concrete building and its construction method. The building comprises a plurality of prefabricated room modules of steel, each including at least one column having a structure of hollow steel tube, which has an inner chamber inserted with penetrating rebars and poured with concrete. The penetrating rebars extend upwardly out of the column of the prefabricated room module into an inner chamber of a column of a prefabricated room module of an upper floor.

Abstract: Disclosed herewith a prefabricated bathroom and a construction method and an installation method thereof. The prefabricated bathroom includes a bottom unit (11), multiple wall units (12) and a top plate unit (13). One of the wall units (12) is a structural wall (14), which is provided with a recessed top region (141) reserved for later pouring, a middle full-prefabricated structural wall body (142), and a recessed bottom region (143) reserved for later pouring. Top exposed reserve bars (144) of the prefabricated bathroom of a floor are inserted into the recessed bottom region (143) of the prefabricated bathroom of a next floor, and connected with bottom exposed reserve bars (146) thereof, so that the prefabricated bathroom of said floor can be connected with that of said next floor through pouring concrete in the recessed top region (141) and the recessed bottom region (143).

Abstract: Disclosed herewith a prefabricated frame, including a column (1), a main beam (2), a secondary beam (3), and a floor (5). The main beam (2) and the secondary beam (3) are both prefabricated members, and provided with exposed reserve reinforcing bars. The floor (5) is a laminated plate having a prefabricated slab (51) at a lower portion thereof. The prefabricated slab (51), the main beam (2), and the secondary beam (3) are connected together through in-situ casting concrete on respective top portions thereof. The column (1) is a prefabricated column, which has exposed reserve reinforcing bars at a top thereof, and a to-be-cast structure at a bottom thereof for connection with a lower building structure, which has exposed reinforcing bars inserted into the to-be-cast structure. The connection between the column (1) and the lower building structure is achieved by casting in-situ concrete in the to-be-cast structure (12).
