It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Reference Figures 1 to 4 As shown, this invention provides a rotary-positioning modular steel structure building structure, comprising multi-layered unit structures A stacked together. (See reference...) Figure 1 As shown, in this embodiment, the unit structure has three layers: a bottom layer unit structure, a middle layer unit structure, and a top layer unit structure. Each layer of unit structure is formed by connecting four unit structures.

[0039] See Figure 2 As shown, each unit structure A includes a base and a riser 2.

[0040] The base consists of two layers. Each unit structure's base is composed of two layers. Each base layer includes four substrates 11. The four substrates 11 are arranged in a matrix.

[0041] See Figure 6 As shown, the substrate 11 has through holes. A crossbeam 12 connects two adjacent substrates 11 of each base layer.

[0042] Each unit structure has four risers 2. A notch a is formed in the lower end of the riser 2's wall. A bayonet b is formed in the inner wall of the notch a. Insertion connectors 3, coaxially arranged with the riser 2, are formed on the upper end of the riser 2 and on the base plate 11 of the bottom substrate. In this embodiment, the base plate also has variations; see [reference needed]. Figure 1 As shown in Figure 7, a connector is provided on the substrate of the bottom base of the bottom unit structure.

[0043] Specifically, a locking block 31 is formed on the circumferential surface of the connector 3. The upper and lower ends of the riser 2 are movably inserted into the through holes of the base plates 11 of the two base layers. The lower end of the riser 2 is fitted onto the connector 3 on the base. The lower end of the riser 2 of the upper unit structure A is fitted onto the connector 3 on the riser 2 of the lower unit structure A. After the connector 3 is inserted into the lower end of the riser 2, the locking block 31 of the connector 3 is embedded in the notch a. After rotating the riser 2, the locking block 31 is embedded in the bayonet b via the notch a.

[0044] See Figure 8 , Figure 9 and Figure 12 As shown, the substrates 11 of two adjacent unit structures A in the horizontal direction are connected together. Figure 8 The diagram shown is a schematic of a structure in which two substrates are integrally formed.

[0045] Figure 9 The diagram shows a structure formed by four substrates molded as a single unit. Figure 12 This is a schematic diagram of the structure of the upper substrate of the four top-level unit mechanisms, which is integrally formed.

[0046] Continue reading Figure 6 and Figure 10 As shown, a plurality of limiting plates 12 are connected to the base plate 11, and the plurality of limiting plates 12 are spaced apart along the circumferential direction of the perforation. The limiting plates 12 abut against the outer side of the pipe wall of the riser 2.

[0047] In this embodiment, multiple limiting plates 12 are equally spaced along the circumferential direction of the perforation.

[0048] In a preferred embodiment, a guide slope c is formed at the end of the limiting plate 12 that is away from the substrate 11. The guide slope is inclined toward the inside of the perforation.

[0049] See Figures 7 to 9 As shown, the connector 3 includes: ear plate 32 and inner support 33.

[0050] There are multiple ear plates 32. Multiple ear plates 32 are vertically mounted on the upper end of the base plate 11 or the riser 2. The multiple ear plates 32 are evenly spaced along the circumferential direction of the center of the plane of the base plate 11 or the axis of the riser 2. The locking block 31 is disposed on the outside of the multiple ear plates 32.

[0051] The inner support 33 is connected to the inner side of the multiple ear plates 32.

[0052] See Figures 12 to 14 As shown, the roof structure is mounted on the base plate 11 of the upper foundation of the top unit structure A. The connector 3 at the upper end of the riser 2 of the top unit structure A is connected to the roof structure.

[0053] This invention provides a construction method for a rotary-positioning modular steel structure building, characterized by comprising the following steps:

[0054] S1. Construct multiple unit structures A.

[0055] S2. Lay the bottom unit structure A on the ground, install the base plate 11 of the bottom base of the bottom unit structure A on the foundation structure, and connect the base plates 11 of two adjacent unit structures A in the horizontal direction together.

[0056] S3. The multi-layer unit structure A is stacked layer by layer from bottom to top. The lower end of the riser 2 of the upper unit structure A is fitted with the connector 3 on the riser 2 of the lower unit structure A. After the connector 3 is inserted into the lower end of the riser 2, the locking block 31 of the connector 3 is embedded in the notch a. After the riser 2 is rotated, the locking block 31 is embedded in the bayonet b through the notch a, and the base plates 11 of the two adjacent unit structures A in the horizontal direction are connected together.

[0057] In this embodiment, the base is mainly composed of a limiting plate, a connector, and a rectangular base plate welded together. Figure 8 The substrate shown is composed of two substrates, such as... Figure 9 The substrate 4 shown is composed of four substrates.

[0058] After the base plate of the lower base of the bottom structural unit is connected to the foundation structure through the embedded parts, the riser is inserted along the limiting plate. The top guide slope of the limiting plate (serves a guiding function) and the limiting plate positions the edge of the riser, which facilitates the installation and fixing of the riser.

[0059] The upper end of the riser is connected to a circular end plate, on which a connector is installed. The bottom wall of the riser is cut into a "7" shaped groove (formed by an integral combination of a notch and a snap-fit), which is then screwed on and fixed in place with the connector. The connection between the snap-fit ​​and the riser is flattened to increase the stress-bearing area and avoid stress concentration.

[0060] The perforation in the middle of the substrate is made according to the size and shape of the connector.

[0061] The top-level unit structure mainly consists of bolts, lower nuts, circular end plates, and risers.

[0062] The rotary-positioning modular steel structure of this invention is suitable for connecting modular steel structure units. This rotary-positioning modular steel structure is easy to install and disassemble, and can be reused, significantly improving work efficiency during installation and reducing construction costs.

[0063] The rotary-positioning modular steel structure of this invention can better optimize structural installation, accelerate module installation speed, and improve the quality of module connection nodes. This rotary-positioning modular steel structure of the invention features high reliability, wide applicability, and ease of installation, secondary disassembly, and reuse in modular steel structures.
