Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology and relates to a modular building system with rapid self-locking interconnection between boxes. Background Technology

[0002] Modular steel structure buildings, with their advantages of rapid construction, high environmental friendliness, and suitability for standardized production, are highly compatible with the concepts of green building and industrialized construction. Promoting modular construction methods will effectively reduce resource waste and carbon emissions caused by on-site construction. Modular steel structures are highly compatible with the concepts of green building and industrialized construction.

[0003] Modular steel structure buildings refer to a building form that uses prefabricated room units as components, which are then manufactured in a factory and transported to the construction site for assembly. Compared with traditional building structures, modular steel structures offer advantages such as rapid construction, a high degree of prefabrication and assembly, suitability for standardized and industrialized production, and compliance with green building requirements. Currently, modular steel structure buildings are widely used in countries and regions such as Europe, America, and Japan. In China, modular steel structure buildings are mainly 1-3 story buildings converted from shipping containers, with only a few demonstration projects and no large-scale promotion or application yet.

[0004] Currently, there is no universally applicable modular building system, primarily because existing technologies cannot simultaneously satisfy the requirements of rapid connection between modules and good stress distribution at nodes, and do not fully consider the diverse usage needs of buildings and the multi-scenario applications of combining multiple modules. Existing module connection technologies are mainly concentrated at the frame level, which is inconsistent with the design concept of assembling fully furnished room units. Furthermore, existing module splicing typically uses high-strength bolts or welding connections, both of which require considerable construction space and cannot be applied to the central column nodes of modular steel structures. This limits the design to parallel module arrangements, significantly impacting the flexibility of the planar layout in the modular steel structure design process. Therefore, it is necessary to develop a new type of connector that does not require construction space to achieve the connection of central column nodes in modular steel structures. Additionally, due to the uncertainties of the construction site and splicing process, under non-ideal conditions, modules may fail to splice due to installation errors. Installation errors may arise from initial defects in components, on-site assembly deviations, and stress deformation between modules; these errors are difficult to eliminate. As the number of spliced ​​modules increases, the module assembly error problem will become more prominent, necessitating improvements in the error sensitivity of module assembly. Therefore, the widespread application of modular buildings requires comprehensive consideration of characteristics such as efficient on-site assembly, diverse module combinations, construction with wall panels, structural service to the building, and insensitivity to installation errors. Developing a modular building system that integrates these characteristics and addresses every issue is promising for widespread adoption. Therefore, it is necessary to propose a modular building system that requires no additional construction space, automatically compensates for processing errors, is based on assembled fully furnished room units, and considers the layout of water and electricity pipe networks, enabling rapid self-locking interconnection between container units. Summary of the Invention

[0005] The purpose of this invention is to provide a modular building system with rapid self-locking interconnection between cabinets, which enables the rapid assembly of fully furnished room units on the construction site. It features diverse module combinations, flexible spatial layout, and wide application range. It improves the sensitivity to installation errors during module splicing, solves the problem of insufficient construction space during steel module construction, and takes into account the laying of water and electricity pipelines, increases the interconnection of structural components, and enhances the overall structural load-bearing capacity.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A modular building system for rapid self-locking interconnection between enclosures includes several modular room units that can be self-lockingly interconnected in pairs. Each modular room unit includes a main body of the building and several vertical self-locking connectors installed on the main body of the building. Each vertical self-locking connector consists of a lock head and a lock mechanism. The lock mechanism includes a lock rod fixed to the main body of the building. The lock head includes a top plate fixed to the main body of the building, two locking plates movably installed on the top plate and having grooves machined on their surfaces, and an elastic element that connects the locking plates and the top plate at both ends and is used to push the two locking plates closer together. When the locking plates are close together, the grooves on the two locking plates cooperate to form a self-locking groove that constrains the lock rod.

[0008] The lock head and lock are configured such that when two vertically adjacent modular room units are assembled, the lock bar on one of the modular room units pushes open the lock plate on the other modular room unit and engages in the self-locking groove formed by the elastic member, so that the two vertically adjacent modular room units are self-lockingly interconnected.

[0009] Furthermore, the number of locks on the main body of the house and the length of the lock rods can be set according to different requirements. By changing its structural dimensions, the error sensitivity of module splicing can be further reduced.

[0010] Furthermore, due to the design of the elastic element in conjunction with the movable locking plate, the centers of the lock and the lock head do not need to correspond one-to-one; it is sufficient to ensure that the lock head can self-lock with the lock. At the same time, in actual use, it can automatically compensate for manufacturing errors, reducing the sensitivity to errors in module assembly.

[0011] Furthermore, the top plate extends on both sides in a direction perpendicular to the top plate to form L-shaped side plates. The top plate and the locking plate have a degree of freedom perpendicular to the side plates. One end of the elastic member is connected to the side plate, and the other end is connected to the locking plate in a compressed state.

[0012] Furthermore, the end of the locking plate facing the locking rod to be self-locked and interconnected is rounded.

[0013] Furthermore, the elastic element is a self-locking spring.

[0014] Furthermore, the lock also includes two sleeves that are fixed to the main body of the house and run horizontally through it, and the two ends of the lock rod are fixedly connected to the sleeves.

[0015] Furthermore, the modular building system also includes horizontal connectors for connecting two adjacent modular room units in the horizontal direction.

[0016] More preferably, the locks are configured such that the positions of the locks located on the adjacent edge areas of two modular room units correspond one-to-one, and the horizontal connector includes a connecting rod for passing through sleeves located on the two adjacent modular room units, and a connecting plate detachably fixed at both ends of the connecting rod and abutting against the sleeve.

[0017] More preferably, the connecting rod is hollow, and its outer contour dimensions match the hollow portion of the sleeve. The connecting plate is fixed and locked to the sleeve on the horizontally adjacent modular room unit by a tie bolt passing through the connecting rod.

[0018] Furthermore, the main body of the house is assembled from steel columns, steel beams, longitudinal wall panels, transverse wall panels, and floor slabs.

[0019] Furthermore, the docking area of ​​the steel column section of the main body of the house is also provided with an internal locking rod, and a lock is also provided in the corresponding position of the adjacent main body of the house for self-locking interconnection with the internal locking rod.

[0020] Furthermore, the cross-sectional shape of the steel columns can be square tube columns, H-shaped columns, and L-shaped columns; the cross-sectional shape of the steel beams can be tube beams, H-shaped beams, and channel steel beams.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] (1) The modular building system with rapid self-locking interconnection between the boxes can realize rapid assembly between modules on the construction site. The splicing module is a room unit with walls and floors, which conforms to the design concept of "fully decorated" assembly. The connection between modules does not require additional construction space, which solves the installation problem of multi-module connection and does not affect the integrity of the module.

[0023] (2) The module connection does not affect the interior decoration, water and electricity and the external enclosure system, and the modules can be freely assembled. When the upper and lower modules are self-lockingly connected, there are no additional construction procedures on site except for hoisting, which further improves the construction efficiency, and can automatically compensate for processing errors. The configuration is simple and there are few parts, which is conducive to large-scale processing and manufacturing. In addition, the construction space for water and electricity pipeline network is designed.

[0024] (3) The upper and lower module columns are connected by self-locking, which allows for direct force transmission. The interconnection between module beams enhances the overall structural integrity. It meets the need for free combination of multiple modules, has a flexible spatial layout, and a wide range of applications, giving full play to its advantage of being suitable for rapid construction on site.

[0056] The above implementation methods will be described in more detail below with reference to specific embodiments.

[0057] Example 1:

[0058] To enable rapid assembly of fully furnished room units on the construction site and mitigate the sensitivity to installation errors during module splicing, this invention provides a modular building system with rapid self-locking interconnection between units. Its structure can be found in [reference needed]. Figures 1 to 11 As shown, the room includes several modular room units that can be self-locking and interconnected in pairs. Each modular room unit includes a main building structure and several vertical self-locking connectors installed on the main building structure. The main building structure is assembled from steel columns 1, steel beams 2, longitudinal wall panels 4, transverse wall panels 5, and floor slabs 3. An internal locking rod 10 is provided in the docking area of ​​the steel column 1 section of the main building structure. A lock 6 for self-locking interconnection with the internal locking rod 10 is also provided in the corresponding position of adjacent main building sections. The cross-sectional shape of the steel column 1 can be a square tube column, an H-shaped column, or an L-shaped column; the cross-sectional shape of the steel beam 2 can be a pipe beam, an H-shaped beam, or a channel steel beam 2.

[0059] The vertical self-locking connector consists of a lock head 7 and a lock 6. The lock 6 includes a lock rod 602 fixed to the main body of the building (preferably located in the edge area, i.e., at the position of steel beam 2, etc.). The lock head 7 includes a top plate 701 fixed to the main body of the building (again, preferably located in the edge area, i.e., at the position of steel beam 2, etc.), two locking plates 703 movably disposed on the top plate 701 and having grooves machined on their surfaces, and an elastic member 70 connecting the locking plates 703 and the top plate 701 at both ends and used to push the two locking plates 703 closer together. 2 (In this embodiment, the elastic element 702 is a self-locking spring), and when the locking plates 703 are brought together, the slots on the two locking plates 703 cooperate to form a self-locking groove that constrains the locking rod 602; the lock head 7 and the lock 6 are configured such that when two vertically adjacent modular room units are assembled, the locking rod 602 located on one of the modular room units pushes open the locking plate 703 on the other modular room unit and is inserted into the self-locking groove formed by the elastic element 702, so that the two vertically adjacent modular room units are self-lockingly interconnected.

[0060] In this embodiment, the number of locks 6 on the main body of the house and the length of the lock rod 602 can be set according to different requirements. By changing its structural dimensions, the error sensitivity of module splicing can be further reduced.

[0061] Because of the elastic element 702 and the movable locking plate 703, the centers of the lock 6 and the lock head 7 do not need to correspond one-to-one; it is sufficient to ensure that the lock head 7 can self-lock with the lock 6. Furthermore, in actual use, it can automatically compensate for manufacturing errors, reducing the sensitivity to errors in module assembly.

[0062] The top plate 701 extends along both sides in a direction perpendicular to the top plate 701, forming L-shaped side plates. The top plate 701 and the locking plate 703 have a degree of freedom perpendicular to the side plates. One end of the elastic member 702 is connected to the side plate, and the other end is connected to the locking plate 703 in a compressed state. The end of the locking plate 703 facing the locking rod 602 to be self-locked is rounded, which is equivalent to forming a smooth, herringbone-shaped gap between the two locking plates 703, which facilitates the locking rod 602 to be squeezed into the self-locking groove during interconnection.

[0063] The lock 6 also includes two horizontally continuous sleeves 601 fixed to the main body of the house. The two ends of the locking rod 602 are fixedly connected to the sleeves 601. The modular building system also includes a horizontal connector 8 for connecting two horizontally adjacent modular room units. To facilitate the splicing of modules on the same floor, the lock 6 is configured such that the positions of the locks 6 located on the adjacent edges of two modular room units correspond one-to-one. The horizontal connector 8 includes a connecting rod 802 for passing through the sleeves 601 located on the two adjacent modular room units, and a connecting plate 801 detachably fixed at both ends of the connecting rod 802 and abutting against the sleeves 601. The connecting rod 802 is hollow, and its outer contour dimension matches the hollow portion of the sleeve 601. The connecting plate 801 is fixedly locked to the sleeves 601 on the horizontally adjacent modular room units by a tie bolt 803 passing through the connecting rod 802. After the modules on the same floor are spliced, pipelines 9 can be arranged between the locks 6, such as... Figure 9 As shown.

[0064] The modular building system with rapid self-locking interconnection between the containers in this embodiment, such as Figure 11 As shown, rapid assembly between modules can be achieved on the construction site. The splicing module is a room unit with walls and floor slabs 3, which conforms to the design concept of "fully furnished" assembly. No additional construction space is required for the connection between modules, which solves the installation problem of connecting multiple modules and does not affect the integrity of the modules.

[0065] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
