[0046] The following is combined Figures 1 to 9 The present invention describes a prefabricated building 100 and a prefabricated building module 200 for the prefabricated building 100.

[0047] like Figures 1 to 3As shown, a prefabricated building 100 according to a first aspect embodiment of the present invention includes a floor slab 10 and a building module body 20. The building module body 20 may be a single unit or an array of multiple units. In an embodiment where only one building module body 20 is provided, the floor slab 10 covers the opening 203 of the building module body 20. The building module bodies 20 may be arranged in an array, including multiple units stacked vertically or multiple units arranged side-by-side horizontally. In the embodiment where multiple building module bodies 20 are stacked vertically, the floor slab 10 covers the opening 203 of the uppermost building module body 20. In the embodiment where multiple building module bodies 20 are arranged side-by-side horizontally, one or more floor slabs 10 may be provided, and one or more floor slabs 10 may cover the opening 203 of the building module body 20.

[0048] The main building module 20 can be manufactured in the factory and then transported to the construction site to shorten the construction time and increase the construction speed.

[0049] For example, one can refer to Figure 1 The building module body 20 includes a enclosure 201 and a base plate 202. The enclosure 201 is arranged around the base plate 202. One end of the enclosure 201 is connected to the base plate 202, and the other end of the enclosure 201 defines an opening 203. The opening 203 of the building module body 20 faces upward, and the floor slab 10 covers the opening 203 of the uppermost building module body 20.

[0050] When constructing the prefabricated building 100 using the building module body 20 of the above embodiment, firstly, the base plate 202 of the lowest building module body 20 is connected to the site. Then, another building module body 20 is hoisted above the first building module body 20, and the base plate 202 of the upper building module body 20 is connected to the enclosure 201 of the lower building module body 20. The base plate 202 of the upper building module body 20 and the lower building module body 20 define a building space. The base plate 202 of the upper building module body 20 serves as both the bottom plate of the upper building space and the top plate of the lower building space.

[0051] For example, one can refer to Figure 2 The building module body 20 includes a enclosure 201 and a base plate 202. The enclosure 201 is arranged around the base plate 202. One end of the enclosure 201 is connected to the base plate 202, and the other end of the enclosure 201 defines an opening 203. The building module body 20 has one or more such enclosures arranged in an array. The opening 203 of the building module body 20 faces downward. The building module body 20 located at the bottom is supported on the floor slab 10, and the floor slab 10 covers the opening 203 of the building module body 20.

[0052] In the process of building the prefabricated building 100 by using the building module body 20 of the above embodiment, first, the floor 10 is connected with the site, then a building module body 20 is hoisted to the upper side of the floor 10 and connected with the floor 10, and then another building module body 20 is hoisted to the upper side of the building module body 20, and the enclosure 201 of the building module body 20 on the upper side is connected with the base plate 202 of the building module body 20 on the lower side. The base plate 202 of the building module body 20 on the lower side is both the top plate of the building space on the lower side and the bottom plate of the building space on the upper side.

[0053] The prefabricated building 100 according to the embodiment of the present application is formed by connecting the floor 10 and the building module body 20, the building module body 20 includes the enclosure 201 and the base plate 202, and two adjacent building spaces can share the same base plate 202. Therefore, the prefabricated building 100 can meet the deformation and stress performance requirements of the combined structure horizontal component, and the amount of steel used is less than that of the traditional modular frame 205 structure. Compared with the hexahedral building module, the building module body 20 of the embodiment of the present application is a pentahedron, and the assembly steps of the building module body 20 are less, so as to improve the production efficiency of the building module body 20, and further improve the production efficiency of the prefabricated building 100. Compared with the hexahedral building module, the two plate parts need to be directly connected between the two plate parts, and the two plate parts need to be well fitted, and the node connection is difficult. In the embodiment of the present application, the base plate 202 is connected with the enclosure 201, the connection difficulty is smaller, the number of functional parts used for connection can be set smaller, and the degree and possibility of interlayer displacement between the two adjacent building module bodies 20 are smaller. Therefore, the prefabricated building 100 of the embodiment of the present application has a simple structure, can reduce the amount of steel, improve the installation efficiency, and effectively ensure the structural safety of the modular multi-layer combined prefabricated building 100.

[0054] Exemplarily, the enclosure 201 can be formed by connecting a plurality of walls end to end, and the number of walls can be designed as needed. The wall can be a complete whole wall, and the prefabricated building 100 can be connected on the site, and then the wall can be holed as needed, for example, as a door or window. Alternatively, the wall can be pre-holed in the factory, and then the holed part can be selected to be retained or filled and closed according to the requirement.

[0055] Exemplarily, the enclosure 201 can be connected with one side of the base plate 202 in the up-down direction (as shown in FIG. 2B), or the enclosure 201 can be connected with the circumferential side wall of the base plate 202.

[0056] In some embodiments, the building module body 20 can be connected to the building module body 20 adjacent in the horizontal direction by referring to Figure 1 The side of the substrate 202 away from the enclosure 201 is provided with a connecting column foot 204, the enclosure 201 includes a plurality of stand columns 2011, one end of the stand column 2011 is connected with the substrate 202; for the two building module bodies 20 arranged up and down, the connecting column foot 204 of one building module body 20 is sleeved on the other end of the stand column 2011 of the other building module body 20 and connected with the stand column 2011. In the above embodiment, the connecting column foot 204 is in a cylindrical shape, and the connecting column foot 204 is connected with the stand column 2011 by being arranged, so as to realize the connection of the adjacent building module bodies 20 in the horizontal direction, the connection operation is convenient and difficult, there is no requirement for wet operation, and the overall installation efficiency is high.

[0057] Exemplarily, the other end of the stand column 2011 can be provided with a plurality of second connecting holes 2013, the connecting column foot 204 can be provided with a plurality of third connecting holes 2041, and the high-strength bolt can be arranged in the second connecting hole 2013 and the third connecting hole 2041 to connect the stand column 2011 and the connecting column foot 204.

[0058] Exemplarily, the side of the floor slab 10 facing the opening 203 can also be provided with a connecting column foot 204, and the connecting column foot 204 is used to be connected with the stand column 2011 of the building module body 20.

[0059] In some embodiments, the building module body 20 can be connected to the building module body 20 adjacent in the horizontal direction by referring to Figure 3 The plurality of building module bodies 20 are arranged side by side in the horizontal direction, and the prefabricated building 100 further includes a connecting rib, the connecting rib is arranged in the plurality of substrates 202 in the horizontal direction to connect the plurality of substrates 202.

[0060] In some embodiments, the plurality of building module bodies 20 are arranged side by side in the horizontal direction, and the prefabricated building 100 further includes a connecting rib, the connecting rib is arranged in the plurality of floor slabs 10 in the horizontal direction to connect the plurality of floor slabs 10.

[0061] In some embodiments, the plurality of building module bodies 20 are arranged side by side in the horizontal direction, and the prefabricated building 100 further includes a connecting rib, the connecting rib is arranged in the plurality of substrates 202 in the horizontal direction to connect the plurality of substrates 202, and the connecting rib is arranged in the plurality of floor slabs 10 in the horizontal direction to connect the plurality of floor slabs 10.

[0062] In the above embodiment, the floor slabs 10 or the substrates 202 adjacent to each other are connected by the connecting rib, so that the overall structure meets the rigid floor slab 10 assumption, ensures the safety of the structure, and can better realize the connection of the adjacent building module bodies 20 in the horizontal direction, which is conducive to improving the integrity of the prefabricated building 100.

[0063] Exemplarily, the connecting rib can be a prestressed rib, and the two ends of the connecting rib are connected with a pressing member, which is screwed on the connecting rib to be pressed on the base plate 202 or the floor 10.

[0064] In some embodiments, reference can be made to Figure 3 and Figure 8 The plurality of building module bodies 20 are arranged side by side in the horizontal direction, and the fence 201 includes a plurality of columns 2011, the columns 2011 are formed with first connecting holes 2012, and the fabricated building 100 further includes a first connecting piece, which is arranged through the first connecting holes 2012 of the side-by-side adjacent columns 2011 of the two building module bodies 20 to connect the two columns 2011.

[0065] That is to say, for the two building module bodies 20 arranged side by side in the horizontal direction, the columns 2011 close to each other are also connected to each other by the first connecting piece. On the one hand, the connection strength of the adjacent building module bodies 20 in the horizontal direction can be enhanced, which is beneficial to improve the integrity of the fabricated building 100. On the other hand, the overall lateral stiffness formed by the two columns 2011 is better, which can improve the cooperative deformation performance between the columns 2011 and the columns 2011, effectively improve the critical bearing capacity of the columns 2011, and is beneficial to improve the seismic safety of the fabricated building 100.

[0066] Exemplarily, the first connecting piece can be a high-strength bolt.

[0067] Reference can be made to Figure 4 The second aspect of the present application further proposes a fabricated building module 200.

[0068] The fabricated building module 200 according to the second aspect of the present application includes the building module body 20 used in the fabricated building 100 of any of the above embodiments.

[0069] The fabricated building module 200 according to the embodiment of the present application includes the building module body 20 of any of the above embodiments. Since the building module body 20 only includes the fence 201 and one base plate 202 connected with the fence 201, the structure is simple, the amount of steel is less, the connection of the complex beam-column joint in the traditional modular steel structure system can be omitted, and the installation efficiency of the multi-layer composite structure is significantly improved.

[0070] In some embodiments, reference can be made to Figure 4 The fence 201 includes a plurality of columns 2011, and the fabricated building module 200 further includes a support assembly 30, which is detachably connected with the one end of the plurality of columns 2011 close to the opening 203.

[0071] Specifically, the column 2011 can be provided with four (reference can be made to Figure 4) or the column 2011 can also be provided with 6 or 8, etc.

[0072] In the above embodiment, the support assembly 30 is connected with the plurality of columns 2011, so that the plurality of columns 2011 can be constrained to each other, reducing the possibility of shaking, vibration, and fracture of the column 2011 during transportation, that is, the support assembly 30 is used to ensure the structural stability of the building module body 20 in the transportation and installation process in the non-working state.

[0073] After the prefabricated building module 200 is transported to the construction site, the support assembly 30 needs to be detached from the column 2011 to form the building module body 20, and then the building module body 20 is connected and assembled to form the prefabricated building 100. The support assembly 30 is detachably connected with the column 2011, so that the support assembly 30 can be detached, and the detached support assembly 30 can be reused.

[0074] In some embodiments, the other end of the column 2011 is formed with a second connecting hole 2013, and a high-strength bolt is arranged in the second connecting hole 2013 to connect with the support assembly 30. That is, the support assembly 30 and the connecting column foot 204 can jointly form the second connecting hole 2013 to achieve the connection with the other end of the column 2011, thereby reducing the number of openings on the column 2011.

[0075] In some embodiments, the support assembly 30 can be connected with the column 2011 in the following manner: Figure 4 and Figure 10 The support assembly 30 includes at least two first telescopic rods 301 and at least two second telescopic rods 302, the first telescopic rod 301 is detachably connected between two columns 2011, and the second telescopic rod 302 is connected between two first telescopic rods 301.

[0076] In the above technical solution, the first telescopic rod 301 and the second telescopic rod 302 are connected and arranged in the above manner, so that the structural stability of the entire support assembly 30 is better, which is conducive to better maintaining the position of the column 2011 stable; both the first telescopic rod 301 and the second telescopic rod 302 can be telescopic, thereby facilitating the support assembly 30 to adapt to building module bodies 20 of various different specifications and sizes, and reducing the size precision matching requirements of the support assembly 30 and the building module body 20.

[0077] Here, the length of the first telescopic rod 301 can be extended or shortened. For example, the first telescopic rod 301 can be connected with the second telescopic rod 302 in the following manner: Figure 10The first telescopic rod 301 and the second telescopic rod 302 each include a connecting segment 3011 and an adjusting segment 3012. The connecting segment 3011 is sleeved on both ends of the adjusting segment 3012 and is screwed with the adjusting segment 3012. The adjusting segment 3012 is formed with a plurality of stop pieces 3013 arranged along the circumference of the adjusting segment 3012. When the length of the first telescopic rod 301 or the second telescopic rod 302 needs to be adjusted, the adjusting segment 3012 is directly rotated through the stop pieces 3013, so that the connecting segment 3011 is telescoped relative to the adjusting segment 3012.

[0078] Further, the support assembly 30 further includes a connecting component 303 connected to the end of the first telescopic rod 301. The connecting component 303 can include a first plate and a second plate arranged at a set angle and connected. The first plate and the second plate are respectively used to be connected to different wall surfaces of the column 2011.

[0079] For example, the two ends of the second telescopic rod 302 can be provided with a connecting ring 304, which is sleeved on the first telescopic rod 301, so that the first telescopic rod 301 and the second telescopic rod 302 are connected.

[0080] Specifically, the number of the first telescopic rod 301 can be determined according to the number of the columns 2011. The number of the second telescopic rod 302 can be determined according to the number of the first telescopic rod 301. For example, the columns 2011 are provided with four, the first telescopic rod 301 can be provided with two, and the second telescopic rod 302 can be provided with one, two, three, etc. For example, the columns 2011 are provided with six, the first telescopic rod 301 can be provided with three, and the second telescopic rod 302 can be provided with two, three, four, five, six, etc.

[0081] In some embodiments, reference can be made to Figure 4 The fence 201 includes a plurality of walls connected head to tail. The connection between adjacent walls is provided with a column 2011. At least one wall is embedded with a frame 205. The frame 205 is connected with the column 2011. The frame 205 and the column 2011 are both connected with the base plate 202. In the above embodiment, by connecting the frame 205 on the column 2011, the lateral stiffness of the column 2011 can be improved, thereby improving the lateral stiffness of the building module main body 20 in the corresponding axis, and further improving the seismic performance of the fabricated building 100. The base plate 202, the column 2011 and the frame 205 are connected in pairs to form a whole, so as to bear force together and improve the anti-deformation ability of the building module main body 20.

[0082] In the embodiment of the present application, the wall is not the main force bearing member. The wall can be a filler wall. The material of the wall can be set according to actual needs, which is not limited here.

[0083] Exemplarily, one column 2011 can be connected with one frame 205 or can be connected with multiple frames 205.

[0084] Exemplarily, the frame 205 can be welded or connected with the column 2011 through high-strength bolts, and the frame 205 and the column 2011 can be welded or connected with the base plate 202 through high-strength bolts.

[0085] For the multiple building module bodies 20 arranged in a stack from top to bottom, and the openings 203 of the multiple building module bodies 20 face upwards, the frame 205 of the building module body 20 located at the bottom can be connected with the base plate 202 of the building module body 20 located at the top through bolts. Due to machining errors and other reasons, the frame 205 of the building module body 20 located at the bottom can not be well fitted with the base plate 202 of the building module body 20 located at the top. Therefore, the bolt connection mode can reduce the machining precision requirement of the frame 205 and the base plate 202 and reduce the production cost.

[0086] For the multiple building module bodies 20 arranged in a stack from top to bottom, and the openings 203 of the multiple building module bodies 20 face downwards, the frame 205 of the building module body 20 located at the top can be connected with the base plate 202 of the building module body 20 located at the bottom through bolts. Due to machining errors and other reasons, the frame 205 of the building module body 20 located at the top can not be well fitted with the base plate 202 of the building module body 20 located at the bottom. Therefore, the bolt connection mode can reduce the machining precision requirement of the frame 205 and the base plate 202.

[0087] In some embodiments, the frame 205 can be used to arrange fixed electromechanical pipelines, thus also being beneficial to improve the overall structural integration.

[0088] In some embodiments, the frame 205 can be used to arrange fixed electromechanical pipelines, thus also being beneficial to improve the overall structural integration. Figure 9 The frame 205 includes a frame body 2051 and a connecting seat 2052, the connecting seat 2052 includes a first part 2053, a second part 2054, and a reinforcing rib 2055, the first part 2053 is connected between the second part 2054 and the frame body 2051, the second part 2054 is connected with the column 2011, an end surface area of the second part 2054 facing the column 2011 is smaller than an end surface area of the frame body 2051 facing the column 2011, and the reinforcing rib 2055 is connected with the frame body 2051, the first part 2053, and the second part 2054.

[0089] It can be understood that, since the end surface area of the second part 2054 facing the column 2011 is smaller than the end surface area of the frame body 2051 facing the column 2011, compared with the end surface of the entire frame body facing the column being connected by being welded in close contact with the column, the frame body 2051 is connected with the column 2011 through the connecting seat 2052 in the embodiment, the connection difficulty is reduced, the machining size precision of the frame 205 can be reduced, and the machining difficulty of the frame 205 is reduced. Along the extension direction of the column 2011, the connecting seat 2052 can be provided with a plurality of connecting seats 2052 spaced apart, so as to equivalently reduce the calculation length of the lateral resistance capacity of the slender column 2011, and improve the axial critical bearing capacity thereof.

[0090] In the above embodiment, the connecting seat 2052 adopts the above structure, and when the connecting seat 2052 is subjected to loads in various directions, the connecting seat 2052 is not easy to deform, the structural stability is good, and reliable connection of the frame body 2051 and the column 2011 can be achieved.

[0091] Exemplarily, the reinforcing ribs 2055 can be arranged on both sides of the first part 2053 in the horizontal direction, or the reinforcing ribs 2055 can also be arranged on both sides of the first part 2053 in the vertical direction (for reference Figure 9 ).

[0092] In some embodiments, the base plate 202 comprises a first decorative layer, a rigid structure layer 2021 and a second decorative layer arranged in sequence, the rigid structure layer 2021 is formed with accommodating cavities 2022 for accommodating pipelines (for reference Figures 4 to 7 ), and the adjacent accommodating cavities 2022 are provided with reserved holes 2023 for penetrating the connecting ribs.

[0093] Exemplarily, the rigid structure layer 2021 can be a steel frame layer or a reinforced concrete layer. The first decorative layer and the second decorative layer can be a composite wood board layer, a ceramic tile layer, a gypsum layer, a stainless steel plate layer and the like to play the role of decoration, covering the rigid structure layer 2021, sound insulation and the like. The rigid structure layer 2021 is formed with the accommodating cavities 2022, and the accommodating cavities 2022 can be provided with pipelines in advance when the factory is prefabricated, or the pipelines can be arranged at the construction site.

[0094] By arranging the accommodating cavities 2022 in the rigid structure layer 2021 in advance, the possibility of causing great damage to the overall structure of the base plate 202 by subsequent pipeline arrangement can be reduced, which is beneficial to make the base plate 202 have good use performance.

[0095] The reserved holes 2023 are arranged for the connection bars, that is, the pipeline and the connection bar can be arranged separately, so that the possibility of corrosion and damage of the connection bar caused by the contact between the pipeline leakage material and the connection bar can be reduced, the service life of the connection bar can be prolonged as much as possible, and the possibility that the use reliability of the prefabricated building 100 is affected can be reduced.

[0096] In some embodiments, the yield strength of the column 2011 is greater than 400 MPa, the diameter of the cross section of the column 2011 is less than 200 mm, and the wall thickness of the column 2011 is less than 10 mm. That is, the yield strength of the column 2011 is greater, and the size of the column 2011 is smaller, so that the structural strength of the prefabricated building 100 can be higher, and the usable area of the prefabricated building 100 can be larger with the same floor area.

[0097] For example, the column 2011 can be made of super-strong steel with a yield strength of 460 Mpa-550 Mpa, the diameter of the cross section of the column 2011 can be 150 mm or 100 mm or less, and the wall thickness of the column 2011 can be 6 mm or less.

[0098] The prefabricated building 100 in the embodiments of the present application is generally used as a permanent building, and the prefabricated buildings in the related art are mostly three floors or less. The prefabricated building 100 in the embodiments of the present application has higher lateral stiffness, better connection stiffness between the building module bodies 20, and more connection points, so that the floor height can reach six floors, breaking through the three-floor use scenario of the prefabricated building in the related art.
