Description
Technical Field
[0001] The utility model relates to the field of prefabricated buildings, and particularly relates to a modular building unit with high space utilization rate. Background Art
[0002] Modular building is a new type of prefabricated building in which factory prefabricated modular units are transported to the site and installed as a whole. The factory prefabricated modular units include both load-bearing structural bodies and building components such as enclosure decoration and mechanical and electrical pipelines, which can significantly reduce the secondary masonry and late decoration workload on site, shorten the construction period, and improve the project quality at the same time. Due to the above construction advantages, modular buildings have been widely used in low-rise buildings such as emergency hospitals, project command posts, urban exhibition halls, and cultural and tourism buildings.
[0003] Embedded modular buildings use a frame structure as the main load-bearing structure, and the modular units provide internal building space and functions. It is a construction plan that can promote modular buildings to permanent multi-story and high-rise buildings. In order to save steel consumption and improve on-site workload, a sparse frame structure with large storey height and large column spacing is also proposed. However, the modular units used in existing engineering projects are all standard six-sided cubes. When they are embedded in the frame structure, there will be conflicts with the frame columns and frame beams in terms of architecture. To avoid the frame columns and frame beams, the modular units will significantly reduce the usable building space, and at the same time increase the on-site decoration workload for concealing the protruding frame columns on the building facade. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that in an embedded modular building, the unit can achieve geometric coordination with the frame columns and frame beams respectively in the building plane and the building elevation, which not only improves the space utilization rate of the modular unit, but also reduces the workload of later on-site facade decoration. For this purpose, a modular building unit with high space utilization rate is proposed.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a modular building unit with high space utilization rate, including two types: modular unit I and modular unit II. The modular unit I is composed of a structural cube, a cantilever steel beam, an enclosing side plate, and a horizontal plate. The modular unit II is composed of a structural cube, a cantilever steel beam, a top keel, an enclosing side plate, and a horizontal plate.
[0006] Further, both the modular unit I and the modular unit II are processed in the factory based on the structural cube.
[0007] Further, the structural cube includes modular columns, modular beams, and modular corner fittings. The modular columns are welded to the bottom surface of the top modular corner fittings and the top surface of the bottom modular corner fittings, and the modular beams are welded to the side surfaces of the modular corner fittings.
[0008] Furthermore, on the sides of the modular beams or modular corner fittings at the top and bottom of the structural cube, externally welded cantilever steel beams are obtained to form Structure I; on the inner sides of the modular columns of Structure I, enclosure side plates are installed, horizontal plates are installed based on the modular beams at the bottom and the cantilever steel beams, and horizontal plates are installed based on the modular beams at the top and the cantilever steel beams to obtain Modular Unit I.
[0009] Furthermore, on the sides of the modular beams or modular corner fittings at the top and bottom of the structural cube, externally welded cantilever steel beams are obtained to form Structure I; on the top surface of the top modular beam of Structure I, top keels are welded upward to obtain Structure II; on the inner sides of the modular columns of Structure II, enclosure side plates are installed, horizontal plates are installed based on the modular beams at the bottom and the cantilever steel beams, horizontal plates are installed based on the modular beams at the top and the cantilever steel beams (only within the range outside the top keels), enclosure side plates are installed based on the side surfaces of the top keels, and horizontal plates are installed on the top surfaces of the top keels to obtain Modular Unit II.
[0010] The modular building unit described in the present utility model achieves geometric coordination with the frame columns and frame beams of the frame structure on the building elevation through the following methods:
[0011] 1) In the intersection area of Modular Unit I and Modular Unit II with the frame columns, the outer contours of its modular columns, modular beams, modular corner fittings, cantilever steel beams, enclosure side plates, horizontal plates, etc. are all arranged around the frame columns. In this way, geometric coordination between Modular Unit I and Modular Unit II and the frame columns of the frame structure is achieved on the building plane, that is, the column-ringing of Modular Unit I and Modular Unit II;
[0012] 2) In the intersection area of Modular Unit II with the upper frame beam, its top modular beam, modular corner fittings, and the horizontal plate based on the top modular beam are located at the bottom surface of the lower flange of the upper frame beam; the top keel and the enclosure side plates installed on the side surface of the top keel and the horizontal plate on the top surface of the top keel are located inside the frame beam. In this way, geometric coordination between Modular Unit II and the frame beam of the frame structure is achieved on the building elevation, that is, the beam-wrapping of Modular Unit II.
[0013] On the premise of achieving geometric coordination between Modular Unit I and Modular Unit II and the frame structure, each layer of the frame and the modular unit can be constructed on-site in the following order:
[0014] First, install the frame columns of each layer of the frame structure;
[0015] Then, the modular corner fittings at the bottom of Modular Unit I are connected to the top surface of the lower frame beam by bolts or other means to complete the installation of Modular Unit I;
[0016] Then, the modular corner fittings at the bottom of Modular Unit II are connected to the modular corner fittings at the top of Modular Unit I by bolts or other means to complete the installation of Modular Unit II;
[0017] Then, the module corner fittings at the top of the module unit body II are connected to the bottom surface of the lower flange of the upper frame beam above by bolts or other means to complete the installation of the upper frame beam.
[0018] Repeating the above process can complete the on-site construction of the entire modular building.
[0019] Technical principle of the present utility model:
[0020] The embedded modular building unit body of the present utility model realizes the geometric coordination of the module unit body with the frame columns and frame beams on the building elevation through the structural form of welding cantilever steel beams and top keels on the basis of a structural cube. Specifically, the present utility model can bring the following advantages:
[0021] (1) The adjacent module unit bodies on the same floor form a ring around the column at the intersection area with the frame column. The unit body does not have to avoid the frame column, which may cause the frame column on the outer facade to protrude. This not only increases the building area but also avoids the external facade decoration construction for concealing the protruding frame column.
[0022] (2) The module unit body forms a bypass around the beam at the intersection area with the upper frame beam. By extending the top keel of the unit body upward into the height range of the frame beam, the building net clear height is maximally increased.
[0023] In summary, the module unit body of the present utility model can maximize the space utilization rate of the embedded module unit through the method of surrounding columns and bypassing beams, and at the same time reduce the workload of the later on-site facade decoration, becoming a more efficient new module unit form suitable for embedded modular buildings.

[0036] The following further explains the present utility model in conjunction with the drawings and embodiments.
[0037] Refer to Figures 1-5 , A module building unit with high space utilization rate, including two types: module unit I and module unit II. The module unit I is composed of a structural cube, a cantilever steel beam, an enclosure side plate, and a horizontal plate. The module unit II is composed of a structural cube, a cantilever steel beam, a top keel, an enclosure side plate, and a horizontal plate. Both the module unit I and the module unit II are processed in the factory based on the structural cube.
[0038] As Figure 1 shown, the structural cube includes a module column 1, a module beam 2, and a module corner fitting 3. The bottom surface of the top module corner fitting 3 of the module column 1 and the top surface of the bottom module corner fitting 3 are welded, and the module beam 2 is welded to the side surface of the module corner fitting 3.
[0039] As Figures 2-3 shown, on the side surface of the module beam 2 or the module corner fitting 3 at the top and bottom of the structural cube, a cantilever steel beam 4 is welded outward to obtain structure I; an enclosure side plate 5 is installed inside the module column 1 of structure I, a horizontal plate 6 is installed based on the bottom module beam 2 and the cantilever steel beam 4, and a horizontal plate 6 is installed based on the top module beam 2 and the cantilever steel beam 4 to obtain module unit I.
[0040] As Figures 4-5As shown in the figure, on the sides of the modular beams 2 or the modular corner fittings 3 at the top and bottom of the structural cube, the cantilever steel beams 4 are welded outward to obtain the structure I; on the top surface of the top modular beam 2 of the structure I, the top keel 7 is welded upward to obtain the structure II; on the inner side of the modular column 1 of the structure II, the enclosing side plates 5 are installed, the horizontal plates 6 are installed based on the bottom modular beam 2 and the cantilever steel beam 4, the horizontal plates 6 are installed based on the top modular beam 2 and the cantilever steel beam 4 (only within the range outside the top keel), the enclosing side plates 5 are installed based on the side surface of the top keel 7, and the horizontal plates 6 are installed on the top surface of the top keel 7 to obtain the modular unit II.
[0041] The processing of the modular unit I and the modular unit II is completed in the factory environment. In the actual project, the internal mechanical and electrical pipelines and building decorations can be laid on the enclosing side plates and the horizontal plates according to the design requirements.
[0042] Figures 6-7 It involves the geometric coordination relationship between the new modular unit and the frame structure in the building plane and the building elevation. As Figure 6 shown, for the frame structure with 1 bay in the transverse direction and 2 bays in the longitudinal direction, 2 columns of modular units are installed between the frame columns 8 in each transverse bay, and 1 row of modular units is installed between the frame columns 8 in each longitudinal bay. Finally, 2 rows and 2 columns of modular units are installed on each floor of the frame in this example; as Figure 7 shown, 2 layers of modular units are installed for each 1 - layer frame structure, which are the modular unit I and the modular unit II from bottom to top in sequence.
[0043] To achieve the geometric coordination relationship between the modular unit I, the modular unit II and the frame column 8 and the frame beam 9, the size and positioning of the cantilever steel beam 4 should be determined according to the size of the modular beam 2, the modular corner fitting 3, and the geometric position relationship with the adjacent frame column 8, etc.; the size and positioning of the top keel 7 should be determined according to the size of the modular beam 2, the geometric position relationship between the modular unit II and the upper - layer frame beam 9, etc.
[0044] As Figure 6 shown, in the intersection area of the modular unit I, the modular unit II and the frame column 8, the outer contours of the modular column 1, the modular beam 2, the modular corner fitting 3, the cantilever steel beam 4, the enclosing side plate 5, the horizontal plate 6, etc. are all arranged around the frame column. In this way, the geometric coordination between the modular unit I, the modular unit II and the frame column 8 of the frame structure in the building plane is achieved.
[0045] As Figure 7As shown in the figure, in the area where the module unit body II intersects with the upper frame beam 9, the top module beam 2, the module corner fitting 3, and the horizontal plate 6 based on the top module beam are located at the bottom surface of the lower flange of the upper frame beam 9; the top keel 7, the enclosure side plate 5 installed on the side surface of the top keel, and the horizontal plate 6 on the top surface of the top keel are located inside the frame beam 9. In this way, the geometric coordination between the module unit body II and the frame beam 9 of the frame structure is achieved on the building elevation.
[0046] The actual number of module unit bodies installed in each floor and each span of the frame structure should be determined according to factors such as the load-bearing and deformation resistance capabilities of the frame columns 8 and frame beams 9, and the weight of the module unit bodies. However, the change in the number of module unit bodies embedded in the frame structure does not affect the coordination relationship between the unit bodies and the frame structure.
[0047] Figures 8-11 It involves the construction process on-site of the new type of module unit body and the frame structure. As Figure 8 shown, first install the frame columns of each floor of the frame structure; as Figure 9 shown, the module corner fitting 3 at the bottom of the module unit body I is connected to the top surface of the lower frame beam 9 by bolts or other means to complete the installation of the module unit body I; as Figure 10 shown, the module corner fitting 3 at the bottom of the module unit body II is connected to the module corner fitting 3 at the top of the module unit body I by bolts or other means to complete the installation of the module unit body II; as Figure 11 shown, the module corner fitting 3 at the top of the module unit body II is connected to the bottom surface of the lower flange of the upper frame beam 9 by bolts or other means to complete the installation of the upper frame beam. Repeating the above process can complete the on-site construction of the entire modular building.
[0048] On the basis of the structural cube, the new type of module unit body realizes the geometric coordination between the module unit body and the frame columns 8 and frame beams 9 on the building plan and elevation through the construction form of welding the cantilever steel beam 4 and the top keel 7: the adjacent module unit bodies I and II on the same floor achieve surrounding the column in the area where they intersect with the frame column 8, and the unit body does not have to cause the frame column 8 on the exterior facade to protrude in order to avoid the frame column, which not only increases the building area but also can avoid the exterior facade decoration construction for concealing the protruding frame column 8; the module unit body II realizes surrounding the beam in the area where it intersects with the upper frame beam 9, and the top keel 7 of the unit body extends upward into the beam height range of the frame beam 9 to maximize the building net space. In summary, through surrounding the column and surrounding the beam, the module unit body can maximize the space utilization rate and at the same time reduce the workload of the later on-site facade decoration.
