Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated building and a prefabricated building module. Background Art

[0002] Modular steel structure buildings have prominent advantages such as high standardization and industrialization levels, and fast construction speed, and have now become an important direction for the development of building industrialization. A fast and reliable connection node between modules is the key to giving full play to the advantages of modular buildings and ensuring the integrity of the structure.

[0003] In related technologies, modular steel structure building modules are mostly hexahedron frame structures, and there are a large number of overlapping composite floors in the multi-layer composite structure formed by modular steel structure building modules. Therefore, there are problems such as excessive steel consumption, strength redundancy, and low production efficiency. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a prefabricated building, which has less steel consumption and high production efficiency while meeting the requirements of deformation and mechanical properties.

[0005] The prefabricated building module according to the first aspect embodiment of the present invention includes a floor slab and a building module main body. The building module main body includes a surrounding wall and a base plate. The surrounding wall is arranged around the base plate. One end of the surrounding wall is connected to the base plate, and the other end of the surrounding wall defines an opening. One or a plurality of the building module main bodies are arranged in an array; the opening of the building module main body faces upward, and the floor slab covers the opening of the building module main body located at the uppermost position; or, the opening of the building module main body faces downward, and the building module main body located at the lowermost position is supported on the floor slab and the floor slab covers and seals the opening of the building module main body.

[0006] The prefabricated building according to an embodiment of the present invention is formed by assembling and connecting a floor slab and a main building module. The main building module includes a fence and a base plate. Two adjacent building spaces can share the same base plate. Therefore, while meeting the requirements of the deformation and mechanical properties of the combined structure's horizontal members, the steel consumption of the prefabricated building is less than that of the traditional modular frame structure. Compared with the hexahedral building module, the main building module in the embodiment of the present application is pentahedral, and the assembly steps of the main building module are fewer. Therefore, it is beneficial to improve the production efficiency of the main building module, and further improve the production efficiency of the prefabricated building. Compared with the assembly of the hexahedral building module that requires direct connection between two plate members and requires good fitting between the two plate members, the connection difficulty at the node is large. In the embodiment of the present application, the base plate is connected to the fence, the connection difficulty is smaller, the number of functional components for connection can be set less, and at the same time, the degree and possibility of inter-story displacement between two adjacent main building modules are also smaller. Thus, the prefabricated building in the embodiment of the present application has a simple structure, can reduce the steel consumption, improve the installation efficiency, and effectively ensure the structural safety of the modular multi-story combined prefabricated building.

[0007] In some embodiments, connection column feet are provided on a side of the base plate facing away from the fence. The fence includes a plurality of columns, and one end of each column is connected to the base plate.

[0013] According to an embodiment of the second aspect of the present invention, the prefabricated building module includes a building module main body. Since the building module main body only includes a surrounding enclosure and a base plate connected to the surrounding enclosure, the structure is simple and the steel consumption is less. The connection of complex beam-column joints in the traditional modular steel structure system can be omitted, significantly improving the installation efficiency of the multi-story composite structure.

[0014] In some embodiments, the surrounding enclosure includes a plurality of columns, and the prefabricated building module further includes a support assembly, and the support assembly is detachably connected to one end of the plurality of columns close to the opening.

[0046] The following will be combined with Figures 1 to 9 to describe the prefabricated building 100 of the present invention and the prefabricated building module 200 for the prefabricated building 100.

[0047] As Figures 1 to 3As shown in the figure, the prefabricated building 100 according to the embodiment of the first aspect of the present invention includes a floor slab 10 and a building module main body 20. The building module main body 20 is provided with one or a plurality of arranged in an array. For the embodiment in which the building module main body 20 is provided with only one, the floor slab 10 covers the opening 203 of the building module main body 20. The building module main bodies 20 are arranged in an array, including a plurality of building module main bodies 20 arranged in a stacked manner in the up and down direction, or a plurality of building module main bodies 20 arranged side by side in the horizontal direction. For the embodiment in which a plurality of building module main bodies 20 are arranged in a stacked manner in the up and down direction, the floor slab 10 covers the opening 203 of the uppermost building module main body 20. For the embodiment in which a plurality of building module main bodies 20 are arranged side by side in the horizontal direction, the floor slab 10 can be provided with one or more, and one or more floor slabs 10 cover the opening 203 of the building module main body 20.

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

[0049] Exemplarily, reference can be made to Figure 1 , the building module main body 20 includes a fence 201 and a base plate 202. The fence 201 is arranged around the base plate 202. One end of the fence 201 is connected to the base plate 202, and the other end of the fence 201 defines an opening 203; the opening 203 of the building module main body 20 faces upward, and the floor slab 10 covers the opening 203 of the uppermost building module main body 20.

[0050] When building the prefabricated building 100 using the building module main body 20 of the above embodiment, first connect the base plate 202 of the lowermost building module main body 20 to the site, and then hoist another building module main body 20 above this building module main body 20, and connect the base plate 202 of the upper building module main body 20 to the fence 201 of the lower building module main body 20. The base plate 202 of the upper building module main body 20 and the lower building module main body 20 define a building space. The base plate 202 of the upper building module main body 20 is both the bottom plate of the upper building space and the top plate of the lower building space.

[0051] Exemplarily, reference can be made to Figure 2 , the building module main body 20 includes a fence 201 and a base plate 202. The fence 201 is arranged around the base plate 202. One end of the fence 201 is connected to the base plate 202, and the other end of the fence 201 defines an opening 203. The building module main body 20 is provided with one or a plurality of arranged in an array; the opening 203 of the building module main body 20 faces downward, and the lowermost building module main body 20 is supported on the floor slab 10 and the floor slab 10 covers and seals the opening 203 of the building module main body 20.

[0052] When assembling the prefabricated building 100 with the building module body 20 of the above embodiment, first connect the floor slab 10 to the site, then hoist a building module body 20 above the floor slab 10 and connect it to the floor slab 10, and then hoist another building module body 20 above the building module body 20, and connect the enclosure 201 of the building module body 20 located above to the base plate 202 of the building module body 20 located below. The base plate 202 of the building module body 20 located above and the base plate 202 of the building module body 20 located below define a building space, so that the base plate 202 of the building module body 20 located below serves as both the top plate of the building space located below and the bottom plate of the building space located above.

[0053] The prefabricated building 100 according to the embodiment of the present invention is assembled and connected by the floor slab 10 and the building module body 20. The building module body 20 includes an enclosure 201 and a base plate 202. Two adjacent building spaces can share the same base plate 202. Therefore, while the prefabricated building 100 meets the requirements of the deformation and mechanical properties of the combined structural horizontal members, its steel consumption 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 pentahedral, and the assembly steps of the building module body 20 are fewer. Therefore, it is beneficial 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 assembly of the hexahedral building module that requires direct connection between two plate members and good fitting between the two plate members, the node connection is difficult. In the embodiment of the present application, the base plate 202 is connected to the enclosure 201, the connection difficulty is smaller, the number of functional parts for connection can be set less, and the degree and possibility of interlayer displacement between two adjacent building module bodies 20 are also smaller. Thus, the prefabricated building 100 of the embodiment of the present application has a simple structure, can reduce the steel consumption, improve the installation efficiency, and effectively ensure the structural safety of the modular multi-story combined prefabricated building 100.

[0054] Exemplarily, the enclosure 201 can be formed by connecting multiple walls end to end, and the number of walls can be designed according to needs. The wall can usually be a complete whole wall. After the prefabricated building 100 is connected to the site, holes are opened in the wall as needed, such as door openings or window openings. Or, the wall can also be pre-opened in the factory in advance, and then the opening is selected to be retained or filled and closed according to the needs.

[0055] Exemplarily, the enclosure 201 can be connected to one side surface of the base plate 202 in the up-down direction (as Figures 1 to 4 shown), or the enclosure 201 can also be connected to the circumferential side wall of the base plate 202.

[0056] In some embodiments, reference may be made to Figure 1 Figure 1 , on the side of the substrate 202 facing away from the enclosure 201, there are connecting column feet 204. The enclosure 201 includes a plurality of upright columns 2011, and one end of the upright column 2011 is connected to the substrate 202; for two building module bodies 20 arranged vertically, the connecting column feet 204 of one building module body 20 are sleeved on the other end of the upright column 2011 of the other building module body 20 and are connected to the upright column 2011. In the above embodiments, the connecting column feet 204 are cylindrical. By providing the connecting column feet 204 to connect with the upright columns 2011, the connection of adjacent building module bodies 20 up and down can be realized. The connection operation is convenient and has little difficulty, there is no requirement for wet work, and the overall installation efficiency is high.

[0057] Exemplarily, a plurality of second connection holes 2013 may be provided at the other end of the upright column 2011, and a plurality of third connection holes 2041 may be provided on the connecting column feet 204. High-strength bolts may pass through the second connection holes 2013 and the third connection holes 2041 to connect the upright column 2011 and the connecting column feet 204.

[0058] Exemplarily, the connecting column feet 204 may also be provided on the side of the floor slab 10 facing the opening 203, and the connecting column feet 204 are used to connect with the upright columns 2011 of the building module body 20.

[0059] In some embodiments, reference may be made to Figure 3 Figure 3 , a plurality of building module bodies 20 are arranged side by side in the horizontal direction, and the prefabricated building 100 further includes connecting bars, and the connecting bars are horizontally inserted through a plurality of substrates 202 to connect the plurality of substrates 202.

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

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

[0062] In the above embodiments, by connecting the adjacent floor slabs 10 or substrates 202 side by side with the connecting bars, the overall structure meets the rigid floor slab 10 assumption, ensuring structural safety. The connection of adjacent building module bodies 20 in the horizontal direction can be better realized, which is beneficial to improving the integrity of the prefabricated building 100.

[0063] Exemplarily, the connecting bars can be prestressed bars, and compression members are connected to both ends of the connecting bars. The compression members are screwed onto the connecting bars to be pressed against the substrate 202 or the floor slab 10.

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

[0065] That is to say, for two adjacent building module bodies 20 arranged side by side in the horizontal direction, their adjacent columns 2011 close to each other are also connected to each other through the first connecting member. On the one hand, the connection strength between adjacent building module bodies 20 in the horizontal direction can be enhanced, which is beneficial to improving the integrity of the prefabricated building 100; on the other hand, the overall lateral stiffness formed by the two columns 2011 is better, the co-deformation performance between the columns 2011 can be improved, the critical bearing capacity of the columns 2011 can be effectively increased, and it is beneficial to improving the seismic safety of the prefabricated building 100.

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

[0067] Reference can be made to Figure 4 , the second aspect of the present invention also proposes a prefabricated building module 200.

[0068] The prefabricated building module 200 according to the embodiment of the second aspect of the present invention includes a building module body 20, and the building module body 20 is used for the prefabricated building 100 of any of the above embodiments.

[0069] The prefabricated building module 200 according to the embodiment of the present invention includes the building module body 20 of any of the above embodiments. Since the building module body 20 only includes the enclosure 201 and a substrate 202 connected to the enclosure 201, therefore, the structure is simple, the steel consumption is less, the connection of complex beam-column joints 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 enclosure 201 includes a plurality of columns 2011. The prefabricated building module 200 further includes a support assembly 30, and the support assembly 30 is detachably connected to one end of the plurality of columns 2011 close to the opening 203.

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

[0072] In the above embodiments, the support assembly 30 is connected to a plurality of upright columns 2011, so as to enable the plurality of upright columns 2011 to restrain each other, reducing the possibility of the upright columns 2011 shaking, vibrating, and breaking during transportation, that is, the support assembly 30 is used to ensure the structural stability of the building module main body 20 during transportation and installation in the non-working state.

[0073] After transporting the prefabricated building module 200 to the construction site, it is necessary to disassemble the support assembly 30 from the upright column 2011 to form the building module main body 20, and then connect and assemble the building module main body 20 to form the prefabricated building 100. The support assembly 30 is detachably connected to the upright column 2011, so that the support assembly 30 can be disassembled, and the disassembled support assembly 30 can be reused.

[0074] In some embodiments, a second connection hole 2013 is formed at the other end of the upright column 2011, and a high-strength bolt is passed through the second connection hole 2013 to be connected to the support assembly 30. That is to say, the support assembly 30 and the connection column base 204 can jointly use the second connection hole 2013 to realize the connection with the other end of the upright column 2011, thereby reducing the number of openings on the upright column 2011.

[0075] In some embodiments, reference can be made to 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 rods 301 are detachably connected between two upright columns 2011, and the second telescopic rods 302 are connected between two first telescopic rods 301.

[0076] In the above technical solution, the first telescopic rods 301 and the second telescopic rods 302 are connected and arranged in the above manner. In this way, the structural stability of the entire support assembly 30 is better, which is beneficial to better keeping the position of the upright column 2011 stable; both the first telescopic rods 301 and the second telescopic rods 302 can be telescopic, which is beneficial to making the support assembly 30 adapt to building module main bodies 20 of various different specifications and sizes, and reducing the dimensional accuracy matching requirements of the support assembly 30 and the building module main body 20.

[0077] Here, the length of the first telescopic rod 301 can be extended or shortened. Exemplarily, reference can be made to Figure 10, both the first telescopic rod 301 and the second telescopic rod 302 include a connecting section 3011 and an adjusting section 3012. The connecting section 3011 is sleeved at both ends of the adjusting section 3012 and is screwed to the adjusting section 3012. The adjusting section 3012 is formed with stoppers 3013, and a plurality of stoppers 3013 are provided along the circumferential direction of the adjusting section 3012. When it is necessary to adjust the length of the first telescopic rod 301 or the second telescopic rod 302, the adjusting section 3012 is directly rotated through the stopper 3013, so that the connecting section 3011 can be telescoped relative to the adjusting section 3012.

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

[0079] Exemplarily, connecting rings 304 may be provided at both ends of the second telescopic rod 302. The connecting rings 304 are 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 rods 301 can be determined according to the number of the columns 2011 provided, and the number of the second telescopic rods 302 can be determined according to the number of the first telescopic rods 301 provided. For example, if there are four columns 2011, two first telescopic rods 301 can be provided, and the second telescopic rods 302 can be provided with one, two, three, etc. For example, if there are six columns 2011, three first telescopic rods 301 can be provided, and the second telescopic rods 302 can be provided with two, three, four, five, six, etc.

[0081] In some embodiments, reference may be made to Figure 4 , the enclosure 201 includes a plurality of walls connected end to end. Columns 2011 are provided at the joints between adjacent walls. At least one wall is embedded with a frame 205. The frame 205 is connected to the column 2011, and both the frame 205 and the column 2011 are connected to the base plate 202. In the above embodiments, by connecting the frame 205 to the column 2011, the lateral stiffness of the column 2011 can be improved, thereby improving the lateral stiffness of the corresponding axis of the building module main body 20, and further being beneficial to improving the seismic performance of the prefabricated building 100. The base plate 202, the column 2011 and the frame 205 are connected to each other to form an integral body, so that they can jointly bear the force, which is beneficial to improving the anti-deformation ability of the building module main body 20.

[0082] In the embodiments of the present application, the wall is not used as a main load-bearing member. The wall can be a filling wall, and the material of the wall can be set according to actual needs, and no specific limitation is made here.

[0083] Exemplarily, a column 2011 may be connected to a frame 205 or may be connected to multiple frames 205.

[0084] Exemplarily, the frame 205 may be welded to the column 2011 or connected by high-strength bolts. The frame 205 and the column 2011 may both be welded to the base plate 202 or connected by high-strength bolts.

[0085] For multiple building module bodies 20 stacked vertically, and when the openings 203 of the multiple building module bodies 20 face upward, the frame 205 of the building module body 20 located below may be connected to the base plate 202 of the building module body 20 located above by bolts. Due to processing errors and other reasons, the frame 205 of the building module body 20 located below may not fit well with the base plate 202 of the building module body 20 located above. Therefore, by using the bolt connection method, the processing precision requirements for the frame 205 and the base plate 202 can be reduced, and the production cost can be reduced.

[0086] For multiple building module bodies 20 stacked vertically, and when the openings 203 of the multiple building module bodies 20 face downward, the frame 205 of the building module body 20 located above may be connected to the base plate 202 of the building module body 20 located below by bolts. Due to processing errors and other reasons, the frame 205 of the building module body 20 located above may not fit well with the base plate 202 of the building module body 20 located below. Therefore, by using the bolt connection method, the processing precision requirements for the frame 205 and the base plate 202 can be reduced.

[0087] In some embodiments, the frame 205 can be used to arrange and fix mechanical and electrical pipelines, which is also beneficial to improving the overall structural integration.

[0088] In some embodiments, reference may be made to Figure 9 , the frame 205 includes a frame body 2051 and a connection seat 2052. The connection 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 to the column 2011. The end face area of the second part 2054 facing the column 2011 is smaller than the end face area of the frame body 2051 facing the column 2011. The reinforcing rib 2055 is connected to the frame body 2051, the first part 2053, and the second part 2054.

[0089] It can be understood that since the end face area of the second part 2054 facing the column 2011 is smaller than the end face area of the frame main body 2051 facing the column 2011, therefore, compared with the end face of the entire frame main body facing the column being bonded and welded to the column, in this embodiment, the frame main body 2051 is connected to the column 2011 through the connecting seat 2052, the connection difficulty is reduced, the processing dimensional accuracy of the frame 205 can be reduced, and the processing difficulty of the frame 205 can be reduced. Along the extending direction of the column 2011, a plurality of connecting seats 2052 can be provided at intervals, so as to equivalently reduce the calculated length of the anti-side ability of the slender column 2011 and improve its axial critical bearing capacity.

[0090] In the above embodiment, the connecting seat 2052 adopts the above structural form. When the connecting seat 2052 is subjected to loads in various directions, the connecting seat 2052 is not prone to deformation, has good structural stability, and can realize the reliable connection between the frame main body 2051 and the column 2011.

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

[0092] In some embodiments, the substrate 202 includes a first decorative layer, a steel structure layer 2021, and a second decorative layer that are sequentially laminated. The steel structure layer 2021 is formed with a receiving cavity 2022 for accommodating pipelines (reference can be made to Figures 4 to 7 ), and a reserved hole 2023 for passing connecting ribs is provided between adjacent receiving cavities 2022.

[0093] Exemplarily, the steel structure layer 2021 can be a steel frame layer, or it can also be 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, etc. to play roles such as decoration, covering the steel structure layer 2021, and sound insulation. The steel structure layer 2021 is formed with a receiving cavity 2022, and pipelines can be set in advance during factory prefabrication in the receiving cavity 2022, or pipelines can also be arranged at the construction site.

[0094] By setting the receiving cavity 2022 in the steel structure layer 2021 in advance, the possibility of causing great damage to the overall structure of the substrate 202 by subsequent pipeline arrangement can be reduced, which is beneficial to enabling the substrate 202 to have better use performance.

[0095] A reserved hole 2023 for passing a connecting rib is provided between adjacent accommodating cavities 2022. By providing a dedicated reserved hole 2023 for arranging the connecting rib, the pipeline and the connecting rib can be separately arranged. Thus, the possibility of the connecting rib being corroded and damaged due to contact between the leaked substance of the pipeline and the connecting rib can be reduced, which is beneficial to extending the service life of the connecting rib as much as possible and reducing the possibility that the service reliability of the prefabricated building 100 is affected.

[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 to say, the column 2011 has a greater yield strength and a smaller self-size. Thus, the structural strength of the prefabricated building 100 can be higher, and with the same floor area, the usable area of the prefabricated building 100 can be larger.

[0097] Exemplarily, the column 2011 can be made of ultra-high-strength steel with a yield strength of 460 Mpa - 550 Mpa, the cross-section diameter of the column 2011 can be 150 mm or 100 mm or smaller, and the wall thickness of the column 2011 can be 6 mm or smaller.

[0098] The prefabricated building 100 in the embodiment of the present application is usually used as a permanent building. Most of the prefabricated buildings in the related art are below three floors. The prefabricated building 100 in the embodiment of the present application has a higher lateral stiffness, better connection stiffness between the building module main bodies 20, and more connection points. Therefore, the storey height can reach six floors, breaking through the three-floor usage scenario of the prefabricated buildings in the related art.
