Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a modular building comprising full-height modular units. Background Technology

[0002] In the field of modular construction, especially in the rapid construction of data centers, a steel structure modular construction scheme is commonly used. This scheme involves prefabricating standardized modular units with pre-defined functions in a factory, then transporting them to the site for hoisting and assembly. A common approach is to stack two standard modular units, one above the other, to form a functional floor. For example, the lower module houses server racks and other equipment, forming an equipment floor, while the upper module is used to install cable trays, pipes, etc., forming a utility tunnel.

[0003] However, this stacked module design inevitably creates a horizontal structural joint because the upper and lower modules are joined at the midpoint of the floor via their respective top and bottom beams. This joint presents several problems: First, the interior wall finish spanning this joint is divided into upper and lower sections, making it difficult to guarantee the overall flatness and aesthetics of the wall surface. Furthermore, it hinders the efficient prefabrication and installation of equipment or decorative components in the factory. Second, vertical pipelines within the building, such as electrical conduits and low-voltage cables, need to be fabricated in two sections, increasing the complexity and workload of on-site construction and introducing additional connection points that may affect system reliability. Finally, in the module joining area, operational space needs to be reserved for on-site module connections. This renders the structural beams in this area unreliable connection points for the integrated pipeline system, forcing designers to adopt special support and hanger solutions, increasing design complexity and construction costs. Utility Model Content

[0004] The purpose of this utility model is to provide a modular building comprising full-height modular units, solving the technical problem in the prior art where the structural discontinuity caused by the stacking of standard modules creates difficulties for wall decoration, vertical pipeline laying, and integrated pipeline system installation. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, this application provides a modular building comprising full-height modular units, including: At least one first module type, wherein the first module type is formed by stacking at least two standard module units in a vertical direction; At least one second module type, wherein the second module type is a through-height module unit; The height of the through-height module unit is matched with the total height of the first module type, so that the first module type and the second module type can be aligned and connected at the top. The dimension of at least one horizontal direction of the full-height module unit matches the corresponding horizontal direction dimension of the standard module unit constituting the first module type, so that the full-height module unit and the standard module unit can be spliced ​​together. The through-height module unit is a single, integrated structural frame, thereby forming a continuous and uninterrupted internal space along its height direction.

[0006] Optionally, the modular building is a data center building.

[0007] Optionally, the full-height module unit is located in the corridor area of ​​the building or used as a pipeline shaft.

[0008] Optionally, in the first module type, the lower standard module unit is used to form an equipment layer, and the upper standard module unit is used to form a pipe gallery layer.

[0009] Optionally, the continuous, uninterrupted interior space is used to accommodate vertical pipelines extending from the upper to the lower part of the first module type.

[0010] Optionally, both the standard module unit and the through-height module unit are steel structure modules.

[0011] Optionally, the adjacent first module type and the second module type are fixedly connected by bolts.

[0012] Optionally, adjacent first module types and second module types are fixedly connected by welding or pinning.

[0013] Compared with existing technologies, the modular building with full-height modular units provided in this application has the following beneficial effects: By introducing full-height modular units compatible with stacked modular systems into the modular building, a complete and continuous interior wall surface is provided, fundamentally solving the problem of uneven wall surfaces caused by modular splicing, improving the building's aesthetics, and creating conditions for high-precision prefabrication and installation of wall equipment, decorative panels, etc. in the factory; At the same time, the continuous and uninterrupted space inside the full-height modular unit allows for the simultaneous laying of vertical pipelines such as electrical and water supply and drainage lines without the need for segmented fabrication and on-site connection, simplifying the construction process and reducing the risk of failure that may be introduced due to too many connection points; In addition, since the connection and operation area of ​​intermediate floors is eliminated, the support and hanger system of integrated pipelines can obtain a continuous and reliable installation interface within the full-height modular unit, eliminating the need to design and manufacture complex irregular components, thereby simplifying the integrated pipeline design and reducing material and construction costs.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This embodiment provides a modular building that includes full-height modular units, which can be applied to scenarios such as data centers.

[0019] In one embodiment of this application, the overall structure of the modular building is composed of two different types of modular units: a first module type 10 and a second module type 20. Both types of modules are highly prefabricated in the factory, including the pre-installation of the main structure, some walls, and electromechanical pipelines, and then transported to the construction site for hoisting and assembly, thereby achieving rapid construction of the building.

[0020] Specifically, the first module type 10 is the basic unit constituting the main functional areas of the building (such as a data center). This first module type 10 is formed by stacking at least two standard module units 11 vertically, in this embodiment, two stacked one above the other. It should be noted that each standard module unit 11 is an independent box-type structure. The standard module unit 11 has preset geometric dimensions; in this embodiment, its outer contour dimensions can be designed as a width of 4062 mm, a depth of 4062 mm, and a height of 3420 mm. The structural frame of this standard module unit 11 is mainly constructed of steel. For example, it has corner posts at its four corners, and the top and bottom are enclosed by top and bottom beams to form a rectangular frame. Secondary beams can be added according to load-bearing requirements. These steel components can be made of Q355B grade steel and assembled in the factory by welding or bolting.

[0021] When two standard module units 11 are stacked one on top of the other, they form the first module type 10 with a total height of 6840 mm. Of course, in actual design, the heights of the two stacked standard module units 11 can be different. In data center applications, this stacking structure has a clear functional division. The lower standard module unit 11 forms the equipment layer, its internal space accommodating and deploying core equipment such as server racks and power distribution cabinets; while the upper standard module unit 11 forms the pipe gallery layer, its internal space mainly used for laying a large number of horizontal pipelines, including but not limited to power cable trays, low-voltage cable trays, air conditioning chilled water pipes, fire water pipes, and ventilation ducts. However, because the bottom beam of the upper module and the top beam of the lower module connect in the middle, a horizontal structural seam 12 is inevitably formed between them. This structural seam runs through the entire first module type 10, thus dividing the building's internal structure.

[0022] To address the problems caused by the aforementioned horizontal structural seam 12, this application introduces a second module type 20. The second module type 20 is a full-height modular unit. Unlike the stacked structure of the first module type 10, this full-height modular unit is a single, integrated structural frame. That is, its main load-bearing structure (e.g., the columns at its four corners) is a complete component extending from the bottom to the top without any structural interruptions. In this embodiment, the structural frame of this full-height modular unit also uses a steel structure and is manufactured in a single process at the factory.

[0023] To achieve seamless integration with the first module type 10, the full-height module unit is meticulously designed with dimensions to match. Firstly, its total height matches the total height of the first module type 10. Specifically, the height of the full-height module unit is designed to be 6840 mm, which is exactly the same as the total height of two standard module units 11 stacked together. This height matching ensures that when the first module type 10 and the second module type 20 are joined side-by-side, they form a flush mating plane at the top and bottom of the building, thus guaranteeing the flatness of the entire building's top platform and bottom foundation. Secondly, at least one horizontal dimension of the full-height module unit matches the corresponding horizontal dimension of the standard module unit 11 constituting the first module type 10. In this embodiment, the depth of the full-height module unit matches the depth of the standard module unit 11, i.e., its depth dimension is 4062 mm. This dimensional matching allows the full-height module unit to be integrated into the overall layout of the building as a standard planar grid unit, ensuring that the modules can be tightly joined to form a regular, continuous building exterior wall or internal partition.

[0024] A significant advantage of using full-height modular units is that, as an integrated structural frame, it forms a continuous and uninterrupted internal space 21 along its height. This internal space 21 extends from the bottom to the top of the full-height modular unit, without any obstruction from transverse structural beams such as horizontal structural seams 12.

[0025] In specific building layouts, these full-height modular units can be strategically placed in specific locations within the building to leverage their structural advantages. For example, in this embodiment, full-height modular units are placed in the corridor area of ​​a data center building. If a traditional corridor area uses the first module type 10, its walls would be divided in two by a horizontal structural seam 12, affecting not only aesthetics but also making it difficult to prefabricate and install equipment such as fire hydrant boxes, switch panels, and evacuation indicator lights in the factory. In contrast, with full-height modular units, the side walls of the corridor (i.e., the inner walls of the full-height modular units) form a completely continuous surface from floor to ceiling, allowing for the direct installation of whole metal wall panels or other decorative materials in the factory, achieving extremely high flatness and aesthetics. Simultaneously, all wall equipment can be precisely pre-installed in the factory, significantly reducing on-site wet work and piecemeal installation tasks.

[0026] Furthermore, the continuous, uninterrupted internal space 21 provides an effective solution to the problem of laying vertical cabling. In data centers, a large number of cablings need to be routed from the upper utility corridor to the lower equipment layer. If the area uses the first module type 10, the cablings must be disconnected and reconnected on-site when crossing the horizontal structural joint 12, which is not only time-consuming and labor-intensive but also increases potential points of failure. In this embodiment, however, the cablings that need to cross vertically can be guided to the adjacent corridor area and laid using the continuous internal space 21 within the full-height module unit. For example, electrical engineers can lay cables from the upper utility corridor cable tray directly and unobstructed from the upper space (over 6 meters high) to the designated location in the lower equipment area in one go, without any intermediate splicing. This significantly simplifies the construction process, shortens the construction period, and improves the reliability of the electrical system.

[0027] Similarly, full-height modular units offer convenience for the installation of supports and hangers in integrated pipeline systems. In the splicing area of ​​traditional stacked modules (i.e., near the horizontal structural joint 12), the structural beams in this area are often unsuitable as installation points for pipeline supports and hangers because space needs to be reserved for workers to tighten bolts between modules. However, in corridor areas using full-height modular units, the main structural beams at the top are continuous and unobstructed, serving as ideal installation bases for integrated pipeline supports and hangers. This allows supports and hangers to be arranged evenly and regularly along the length of the corridor, eliminating the need to design complex irregular or cantilevered supports to avoid connection operation areas, thus simplifying integrated pipeline design and saving costs.

[0028] Regarding module connections, in this embodiment, adjacent first module type 10 and second module type 20, as well as between individual module units, are primarily fixedly connected using high-strength bolts. During factory prefabrication, high-precision bolt holes are pre-drilled on the splicing surfaces of the column or main beam of the module frame. After hoisting and positioning on site, construction workers use a torque wrench to pass high-strength bolts of grade 10.9 or higher through the aligned bolt holes and tighten them to the specified torque, thereby achieving reliable fixing between modules and forming a stable overall structure.

[0029] In summary, this embodiment combines the traditional stacked standard modular unit 11 with an innovative integrated full-height modular unit to construct a hybrid modular building. While retaining the advantages of rapid and efficient modular construction, this solution precisely addresses a series of technical problems in existing technologies caused by horizontal structural joints 12, such as wall discontinuities, pipeline interruptions, and difficulties in installing supports and hangers. This significantly improves the building's intrinsic quality, construction efficiency, and aesthetics.

[0030] In some embodiments, adjacent module units (e.g., between the first module type 10 and the second module type 20) are fixedly connected by a combination of welding and pinning.

[0031] Specifically, the pin-connection structure is mainly used for rapid and precise positioning and temporary fixation during module hoisting. During the manufacturing stage of the module frame, locating pins or corresponding pin holes are pre-machined or welded onto key connection nodes of its corner posts or main beams. For example, a protruding conical or cylindrical locating pin is provided on the side of a corner post of one module, while a pin hole for precise fitting is reserved at the corresponding position in an adjacent module. When the module is hoisted near the target position by a crane, the hoisting worker can guide the locating pin to align with the pin hole. Once the pin engages with the hole, the module achieves millimeter-level precise positioning in the horizontal direction and gains temporary shear and torsional resistance, preventing displacement of the module before final fixation. This pin-connection structure helps improve hoisting efficiency, reduces the precision requirements for worker operation, and provides safety assurance for subsequent permanent connection operations.

[0032] After precise positioning and temporary fixation via the pin-joint structure, construction workers will proceed with permanent welding. Welding is carried out at pre-designed structural nodes on the modular frame, such as the mating surfaces between corner columns of adjacent modules, between top beams, and between bottom beams. To ensure structural strength and durability, high-strength structural welding methods, such as full-penetration bevel welding, are typically employed. Construction workers will use appropriate welding rods or wires, and employ gas-shielded welding (such as CO2 gas shielded welding) or submerged arc welding, according to the welding procedure qualification requirements, to fill the gaps between the buttressing steel plates with weld metal, fusing the two independent modular frames together to form a continuous and rigid connection.

[0033] Compared to bolted connections, the welded connections used in this embodiment have advantages. Firstly, welding provides higher structural integrity and stiffness; the weld seam can transfer stress like the base material, making the entire building structure closer to a single, integrated structure, thus exhibiting superior performance in resisting lateral loads such as earthquakes and strong winds. Secondly, in some cases, welding can simplify the design of connection nodes, avoiding the weakening of component cross-sections caused by a large number of bolts.

[0034] This embodiment demonstrates that the core concept of the hybrid modular building proposed in this application—creating a continuous interior space 21 through full-height modular units with matched height and dimensions—is independent of the specific connection technologies between the modules (whether bolts, welding, pins, or combinations thereof). Regardless of the connection method used, the beneficial effects of the full-height modular units in solving problems such as wall discontinuities and pipeline interruptions can be achieved. Therefore, this embodiment provides an optional implementation method for the technical solution of this application, suitable for building scenarios with higher requirements for earthquake or wind resistance.
