Description

Technical Field

[0001] The invention relates to the field of modular buildings, and in particular to a building module and a connection structure thereof. Background Art

[0002] Box-type modular buildings are the most prefabricated modular buildings. Not only can the interior decoration be completed inside the box, but the building curtain wall can also be fully prefabricated outside the box. It can also be connected to the core tube or other traditional buildings at the project site. It has the characteristics of high degree of prefabrication, less workload on the project site, short project period and recyclability.

[0003] At present, the connection operations between building modules are mainly carried out by bolt connection and welding. Due to the disadvantages of unstable welding quality, large workload and low efficiency in welding at the project site, box-type modular buildings generally do not consider welding for connection operations between building modules. Therefore, bolt connection is the fastest and simplest connection method for box-type modular buildings. Considering that there will be no pre-installed objects blocking the top surface of the building module, and people are allowed to go up during the installation of the building module without the need to build scaffolding, the top surface of the building module is the most suitable operating space for the bolt connection of the upper and lower building modules.

[0004] Although it is currently possible to complete the bolt connection operation of the upper and lower building modules from the top surface of the building module, there are disadvantages such as the use of non-standard parts and the deviation of the upper and lower stacking boxes leading to the failure of the bolt connection.

[0005] Specifically, there are many parts in the above-mentioned bolt connection pair. In order to ensure the convenience of bolt connection, internal and external threaded bolts and the like are used. Internal and external threaded bolts have threads on both the inner and outer surfaces, and are non-standard bolt fasteners that need to be customized. Therefore, they are not suitable for occasions with standard and specification requirements. In addition, during the installation of the stacking boxes of the upper and lower building modules, an opening to be bolted is required on the top surface of the lower building module, and the upper end surface of the opening is flush with the top surface; when the upper building module is placed downward, it is difficult for the bolt fastener of the upper building module to be accurately inserted into the opening. In this way, misalignment is likely to occur between the upper and lower building modules, which ultimately results in the above-mentioned bolt assembly being unable to connect smoothly and causing the connection to fail.

[0048] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0049] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0050] The present invention provides a building module and a connection structure thereof. The connection structure can be applied to the connection and fixation between adjacent building modules, as well as the connection and fixation between each building module and a load-bearing member, and has the advantages of fast and stable connection, accurate positioning, etc. Among them, the load-bearing member includes a foundation, a floor, a column, a wall, and other structural members used for bearing loads.

[0051] First embodiment of building module

[0052] The building module includes columns, multiple end beams, multiple side beams and a connecting structure. The columns are arranged vertically, the end beams and the side beams are arranged horizontally, and the multiple columns, multiple end beams and multiple side beams are connected to form a frame, so that the building module is frame-shaped. In this embodiment, the number of columns, the number of end beams and the number of side beams are all four. The connecting structure is arranged corresponding to the columns to connect the building module with the load-bearing member or the building module with the building module located below it.

[0053] See also Figure 1 , Figure 2 and Figure 3 The column 1 includes a tubular column body 11, a top plate 12 disposed on the top of the column body 11, and a bottom plate 13 disposed on the bottom of the column body 11. The top plate 12 is provided with a mounting hole 121, and the bottom plate 13 is provided with a positioning hole 131.

[0054] In other embodiments, the column 1 is tubular, with both the top and bottom open, and a top corner piece is provided at the top and a bottom corner piece is provided at the bottom. The corner piece holes on the top wall of the top corner piece constitute the mounting holes 121, and the corner piece holes on the bottom wall of the bottom corner piece constitute the positioning holes 131.

[0055] The mounting hole 121 is an elongated hole, and the two ends of the length direction are arc transitions. The positioning hole 131 is a circular hole.

[0056] The connection structure 2 includes a connection cone, a fastener 22 and a fixing member 23, and the connection between the building modules or between the building modules and the foundation is achieved through the cooperation of the above components.

[0057] See also Figure 4 , Figure 5 and Figure 6 The connecting cone includes a cone head 211, a rotating member 212, a limiting member 213 and a clamping member 215 which are arranged in sequence.

[0058] The cone head 211 is used to cooperate with the positioning hole 131 of another building module to achieve rapid positioning of the building module with another building module. The cone head 211 is generally conical, specifically, the outer contour of the cone head 211 is arc-shaped, and the size of the cross section of the cone head 211 gradually increases in the direction close to the rotating member 212, that is, it increases from top to bottom.

[0059] Furthermore, the cross-sectional dimension of the cone head 211 in the direction close to the rotating member 212 is larger than the dimension of the mounting hole, so that the cone head 211 abuts against the top of the structure under the building module.

[0060] A guide chamfer 2111 is provided at the top of the cone head 211, and the inner diameter of the guide chamfer 2111 has an increasing trend in the direction away from the cone head, that is, the inner diameter of the guide chamfer 2111 gradually increases from top to bottom. The purpose is that the conical design of the cone head 211 plus the structural design of the guide chamfer 2111 can play a guiding and positioning role, which is conducive to the rapid positioning of the fastener 22 and improves the efficiency and accuracy of the connection.

[0061] Furthermore, the cone head 211 is provided with a penetrating pin hole 2112, the axis of which is parallel to the axis of the cone head 211, that is, the pin hole 2112 penetrates vertically. In this embodiment, there are two pin holes 2112, which are located on both sides of the axis of the cone head 211.

[0062] See also Figure 6 A connecting column 214 is provided at the bottom of the cone head 211. The connecting column 214 is columnar, that is, the cross section of the connecting column 214 is circular. The axis of the connecting column 214 and the axis of the cone head 211 are located on the same straight line. The diameter of the connecting column 214 is smaller than the size of the bottom of the cone head 211.

[0063] In this embodiment, the connecting column 214 is integrally formed with the cone head 211. In other embodiments, the connecting column 214 can also be connected to the cone head 211 by welding.

[0064] The rotating member 212 is rotatably connected to the cone head 211. Specifically, a through hole is provided on the rotating member 212 for the connection column 214 to pass through, that is, the rotating member 212 is sleeved on the outer periphery of the connection column 214 and is arranged below the cone head 211, thereby realizing the rotatable connection between the rotating member 212 and the cone head 211.

[0065] Specifically, the through hole is circular, and its inner diameter is slightly larger than the outer diameter of the connecting column 214 , so that the rotating member 212 and the cone head 211 can rotate.

[0066] See also Figure 7 The rotating member 212 is in the shape of an elongated plate, and both ends of the length direction thereof are smoothly transitioned. The rotating member 212 is adapted to the mounting hole 121 and can pass through the mounting hole 121. The thickness of the rotating member 212 is consistent with the thickness of the peripheral wall of the mounting hole 121.

[0067] The rotating member 212 is also provided with a matching hole 2121, which is arranged corresponding to the pin hole 2112 on the cone head 211. In this embodiment, there are two pin holes 2112, so there are two matching holes 2121. The two matching holes 2121 are arranged at intervals along the length direction of the rotating member 212 and are arranged on both sides of the through hole.

[0068] When the rotating member 212 rotates until the matching hole 2121 and the pin hole 2112 are located in the same straight line, the pin shaft is inserted into the pin hole 2112 and the matching hole 2121 at the same time to limit the rotation between the rotating member 212 and the cone head 211. In this embodiment, when the length direction of the rotating member 212 is 90° to the length direction of the limiting member 213, that is, when the length direction of the rotating member 212 is parallel to the width direction of the limiting member 213, the matching hole 2121 and the pin hole 2112 are located in the same straight line and communicate with each other.

[0069] Specifically, the height of the pin is greater than the height of the rotating member 212, and is supported by the stopper 213 located below the rotating member 212, so that the pin is clamped in the matching hole 2121 and the pin hole 2112, thereby limiting the rotation between the rotating member 212 and the cone head 211. The height of the pin can be greater than the sum of the heights of the cone head 211 and the rotating member 212, so as to facilitate the insertion or extraction of the pin. A cavity can also be opened in the pin, and the inner peripheral wall of the cavity is provided with an internal thread, and the bolt and the pin are screwed together by a bolt with an external thread, so that the insertion or extraction of the pin is facilitated by the bolt.

[0070] The stopper 213 is fixedly connected to the cone head 211, so that the stopper 213 is also rotationally connected to the rotating member 212, that is, when the cone head 211 rotates, the stopper 213 is driven to rotate, so that the cone head 211 and the stopper 213 are simultaneously rotationally connected to the rotating member 212. Specifically, the stopper 213 is connected to the other end of the connecting column 214 relative to the cone head 211, that is, the bottom end of the connecting column 214.

[0071] The limiting member 213 is in the shape of an elongated plate, and both ends of the limiting member 213 in the length direction are smoothly transitioned. In this embodiment, the size of the limiting member 213 is the same as the size of the rotating member 212 .

[0072] The length of the stopper 213 is less than the length of the mounting hole 121, and the length of the stopper 213 is greater than the width of the mounting hole 121. Therefore, when the length direction of the stopper 213 is parallel to the length direction of the mounting hole 121, the stopper 213 can pass through the mounting hole 121; when the cone head 211 is rotated so that the width direction of the stopper 213 is parallel to the length direction of the mounting hole 121, the stopper 213 cannot pass through the mounting hole 121. At this time, the stopper 213 is located below the top plate 12 and abuts against the top plate 12.

[0073] The connecting cone has an inner cavity which passes through from the top of the cone head 211 to the bottom of the stopper 213. The axis of the inner cavity and the axis of the cone head 211 are located on the same straight line.

[0074] Combination Figure 4 and Figure 8 The clamping member 215 includes a bottom wall 2151 and a plurality of side walls 2152. The bottom wall 2151 is disposed at the other end away from the cone head 211, and a through hole is provided on the bottom wall 2151 for the screw 221 to pass through. The bottom wall 2151 and the plurality of side walls 2152 are combined to form a clamping groove. In this embodiment, the bottom wall 2151 is hexagonal, and the number of the side walls 2152 is three, which are arranged at intervals.

[0075] See also Fig. 9 and Fig.10 The fastener 22 is located in the column 1 and extends downward from the column 1. The fastener 22 specifically includes a screw rod 221, a baffle plate 222 disposed on the top of the screw rod 221, a connecting pipe 223 located above the baffle plate 222, an operating plate 224 located above the connecting pipe 223, and a nut 225.

[0076] The nut 225 is matched with the screw rod 221. The cross section of the nut 225 is hexagonal and matched with the clamping groove.

[0077] The screw rod 221 can be inserted into the inner cavity of the connecting cone and connected with the connecting cone. The screw rod 221 is provided with an external thread, and the nut 225 is provided with an internal thread, so that the screw rod 221 and the nut 225 are screwed together.

[0078] The fastener 22 is connected to the connecting cone by screwing the screw 221 and the nut 225. Specifically, the nut 225 is clamped in the clamping groove of the connecting cone, and the screw 221 passes through the inner cavity of the connecting cone and is screwed with the nut 225, and passes through the through hole on the bottom wall 2151. The nut 225 is clamped in the clamping groove, which avoids the situation that the screw 221 and the nut 225 are difficult to lock during the installation process, and ensures the connection strength. The connecting tube 223 is hollow inside, and an operating hole for operation is opened on the operating plate 224. In this embodiment, the operating hole is a hexagonal through hole for the operator to insert an L-shaped hexagonal wrench for tightening.

[0079] Furthermore, the operation panel 224 is provided with a lower hook 226. The top of the interior of the column 1 is provided with an upper hook 14, and the lower hook 226 can be hung on the upper hook 14, and the fastener 22 is hung in the column 1, so as to facilitate the storage of the fastener 22. Before installation, the fastener 22 is hung on the inner wall of the column 1. During assembly, the operator reaches into the column 1 and removes the fastener 22 from the upper hook 14 for use.

[0080] See also Fig.11 The fixing member 23 is fixed to the bottom of the column 1. Specifically, the fixing member 23 includes a fixing tube 232 erected at the bottom of the column 1 and a fixing plate 231 fixed to the top of the fixing tube 232. The fixing plate 231 is provided with a through hole for the screw 221 to pass through and for limiting the baffle 222 to pass through.

[0081] In this embodiment, the fixing tube 232 is erected on the bottom plate 13 of the column 1 .

[0082] In order to further enable those skilled in the art to understand in detail how the connection structure 2 provided in this embodiment realizes the connection and fixation between building modules, the specific connection process will be described below.

[0083] For the convenience of description, the building module located at the lower level is defined as the lower building module, and the building module located at the upper level is defined as the upper building module.

[0084] S1. Place the lower building module.

[0085] Specifically, the lower building module is horizontally placed at a preset installation position. The lower building module can be the building module in the present application or the building module in the related art. In this case, the building module has a corner piece, and the corner piece hole constitutes the installation hole 121.

[0086] S2. Place the connection cone of the connection structure 2 of the upper building module on the lower building.

[0087] Specifically, the upper building module adopts the building module in the present application, which has a connecting structure 2. The rotating member 212 and the limiting member 213 of the connecting cone are rotated to be consistent in the length direction, and the connecting cone is placed from top to bottom into the mounting hole 121 of the lower building module, so that the rotating member 212 and the top plate 12 are at the same height, and then the cone head 211 is rotated by 90°, so that the width direction of the limiting member 213 is parallel to the length direction of the mounting hole 121, so that the limiting member 213 and the top plate 12 are locked against each other.

[0088] S3. Place the upper building modules so that they are stacked on top of the lower building modules.

[0089] Specifically, the cone head 211 of the connecting cone is passed through the positioning hole 131 of the upper building module to achieve rapid positioning of the upper building module and the lower building module.

[0090] S4. Connect the fastener 22 to the connecting cone to achieve the connection between the upper building module and the lower building module.

[0091] Specifically, the screw rod 221 of the fastener 22 is inserted along the top of the connecting cone, and the screw rod 221 is rotated by using a hexagonal wrench tool in conjunction with the operating hole to make the external thread of the screw rod 221 fit with the internal thread on the inner wall of the inner cavity to achieve threaded connection.

[0092] S5. Insert the pin to limit the rotation between the rotating member 212 and the cone head 211.

[0093] Specifically, when the length direction of the rotating part 212 is parallel to the width direction of the limiting part 213, the matching hole 2121 and the pin hole 2112 are located on the same straight line, and the pin shaft is inserted to limit the rotation between the rotating part 212 and the cone head 211, thereby completing the connection and fixation between the upper building module and the lower building module.

[0094] Through the cooperation between the fastener 22 of the connection structure 2 and the connection cone, and the clamping action between the stopper 213 and the positioning hole 131, the upper building module and the lower building module are protected from vertical tensile forces, thereby preventing the upper building module and the lower building module from moving away from each other in the vertical direction. The cooperation between the rotating member 212 and the mounting hole 121 is used to protect against horizontal shear forces, thereby preventing any relative lateral movement.

[0095] That is, the connection structure 2 of this embodiment realizes a firm and reliable connection between the upper building module and the lower building module in a simple manner. The upper building module and the lower building module are not easily misaligned, and the upper building module and the upper building module are quickly stacked and fixed; the connection operation is simple, the connection is fast and stable, and the construction efficiency of the building module is greatly improved.

[0096] The connection between the building module and the load-bearing component in the present application is described below. The following load-bearing component is described by taking the foundation as an example.

[0097] Please refer to Figures 12 to 15, a basic connecting member 7 is provided on the foundation. The basic connecting member 7 includes a base plate 71 and a fixing column 72 fixed on the base plate 71. The base plate 71 is welded to the embedded parts fixed to the foundation, or the base plate 71 is welded to the steel structure foundation part. A top plate or an angle piece is provided on the top of the fixing column 72, and a mounting hole 721 is provided on the top plate or on the angle piece. The connection process of the building module and the foundation in this application can refer to the connection process of the upper building module and the lower building module, and the lower building module can be replaced by the basic connecting member 7.
