[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] like Figures 1 to 8 As shown, the present invention discloses a single-piece modular combined building structure system, the technical solution of which includes wall panel module 1, H-shaped steel column 2 and floor slab module 3; The wall panel module 1 includes type A, the first-floor wall panel unit, and type B, the standard-floor wall panel unit, depending on the floor it is located on.

[0021] The first-floor wall panel unit serves as the starting floor of the building. It does not have a T-shaped steel beam 11 at the bottom. Instead, it is directly connected to the building foundation by the guide beam 13 of the light steel keel wall frame 12 through the mortar. A T-shaped steel beam 11 is installed at the top. The beam is in an upright position, with the flanges placed horizontally at the bottom and the vertical web facing upwards.

[0022] The standard floor wall panel unit is used for the second floor and above, and it is equipped with T-shaped steel beams 11 at both the top and bottom. The top T-shaped steel beam 11 is upright and is used to support the floor slab module 3; the bottom T-shaped steel beam 11 is inverted, with its flanges placed horizontally at the top and its vertical web facing downwards. Its web is used to connect with the top beam web of the lower wall panel module 1.

[0023] The first-floor wall panel unit has square pre-reserved slots 14 at both ends of the top, and no holes at the bottom. The upper end of the vertical keel inside the first-floor wall panel unit is fixed to the connecting plate 4 on the horizontal flange of the top T-shaped steel beam 11 by high-strength bolts 5, and the lower end is welded to the bottom guide beam 13. The standard floor wall panel unit has square pre-reserved slots 14 at all four corners. The upper and lower ends of the vertical keel inside the standard floor wall panel unit are fixed to the connecting plate 4 on the horizontal flange of the T-shaped steel beam 11 by high-strength bolts 5.

[0024] The connection node between wall panel module 1 and H-shaped steel column 2 forms two mutually perpendicular connection surfaces in space, including a vertical connection surface and a horizontal connection surface, ensuring the stability of the connection. Vertical connection surface: The web of the T-shaped steel beam 11 is aligned with the stiffening plate 23 on the side of the H-shaped steel column 2. High-strength bolts 5 are inserted into the corresponding holes of the web and the connecting plate 4 and tightened to achieve the docking and fixing of the T-shaped steel beam 11 and the H-shaped steel column 2, and to initially define the relative position of the T-shaped steel beam 11 and the H-shaped steel column 2.

[0025] Horizontal connection surface: An L-shaped movable angle plate 6, with a right-angled metal plate as an auxiliary connector, is used. One right-angled side of the movable angle plate 6 is fitted with the flange of the T-shaped steel beam 11, and the other right-angled side is fitted with the corner of the H-shaped steel column 2. High-strength bolts 5 are inserted into the corresponding holes of the movable angle plate 6 and the flange, and the movable angle plate 6 and the H-shaped steel column 2, and tightened to form an auxiliary reinforcement connection.

[0026] The H-shaped steel column 2 has a column base plate 21 welded to its base, which is anchored to the anchor bolt assembly in the concrete foundation. When the column needs to be extended, the end plate 24 is used in conjunction with the high-strength bolt 5 for connection. That is, stiffening plate 23 and end plate 24 are welded to the end of the column, and splicing is carried out on site using high-strength bolt 5. At the height where the column connects to the wall panel module 1 of each layer, a connecting plate 4 with bolt holes is pre-welded, and stiffening plate 23 is set inside the node area to enhance rigidity.

[0027] Floor slab module 3 includes pre-cast reinforced concrete ribs 31 and a base plate 32, which are assembled in the factory using a pre-embedded fastening system. Internally threaded sleeves 34 are pre-embedded within the ribs of the reinforced concrete ribs 31, with the upper opening of the sleeve flush with the concrete bottom surface. After the base plate 32 is in place, machine screws 35 and concealed pressure strips 33 are screwed into the internally threaded sleeves 34 from the back of the decorative surface towards the concrete structure to tighten and fix them. After tightening, a removable decorative cap 36 is placed over the machine screws 35. The base plate 32 directly serves as the finished ceiling surface of the building interior, and the cavity formed between it and the ribs is used for laying pipelines or filling with sound insulation and thermal insulation materials.

[0028] An assembly method for a single-piece modular composite building structure system includes the following steps: Step 1, Foundation Acceptance and Layout: Reserve shear keyways when pouring foundation concrete; Before installation, check the foundation strength and verify the positional accuracy of the keyway and pre-embedded anchor bolts; use a total station to mark the installation position of each wall panel module 1 and H-shaped steel column 2; Step 2, Installation on the first floor: a. Steel column installation: Hoist the H-shaped steel column 2 and fit its column base plate 21 into the foundation pre-embedded anchor bolts; After initially tightening the nuts, temporarily fix the column by installing guy ropes in both directions; use a theodolite to correct the verticality, and finally tighten the nuts to complete the final fixation according to the designed torque value.

[0029] b. Wall panel installation: Lay high-strength, non-shrink mortar at the wall panel location on the foundation; Hoist the first-floor wall panel unit so that its bottom guide beam 13 sits on the mortar. After correcting the verticality, first use high-strength bolts 5 to connect the web of the T-shaped steel beam 11 to the connecting plate 4 on the column; then install the movable corner plate 6 and use high-strength bolts 5 to connect the flange of the top T-shaped steel beam 11 of the wall panel to the H-shaped steel column 2. Step 3: Installation of floor slab and upper layer: a. Floor slab installation: After the grout strength reaches the design value, hoist the first floor slab module 3, so that its reinforced concrete rib plate 31 is supported on the flange of the T-shaped steel beam 11 at the top of the first floor wall panel unit.

[0030] b. Steel column extension: Before hoisting the upper wall panel, first hoist the two sections of the H-shaped steel column of this floor into place, aligning their lower ends with the end plate 24 at the top of the lower column. Use high-strength bolts 5 to penetrate the bolt holes of the end plate 24 and tighten them according to the torque requirements to complete the column extension. c. Upper wall panel installation: Hoist the standard floor wall panel unit, align the web of its bottom T-beam 11 with the web of the top T-beam 11 of the lower wall panel, leaving a pre-designed gap in the middle, and connect it with the connecting plate 4 and high-strength bolts 5; simultaneously complete the connection between the web of the T-beam 11 of this floor wall panel and the connecting plate 4 on the column, and complete the connection between the flange of the T-beam 11 and the H-beam column 2 through the movable corner plate 6.

[0031] Step 4, Cyclic Operation and Finishing: Repeat Step 3, installing layer by layer upwards until the structure is capped.
