Description

BUILDING MODULE AND CONNECTING STRUCTURE THEREOF

BACKGROUND

100011 The present invention relates to the field of modular buildings, and in particular to a building module and connecting structure thereof [0002] Box-type modular building is the fabricated module building with the highest degree of preassembly. Not only the interior decoration can be completed inside the box, but also the curtain wall of the building can be fully preassembled outside the box, and it can also be connected with the core tube or other traditional buildings on the project site, which has the characteristics of high degree of prefabrication, less work on the project site, short project period and recyclable utilization.

[0003] At present, the main modes of connection between building modules are bolted connection pairs and welding. Welding on the projection site leads to the defects of unstable welding quality, heavy workload and low efficiency, so that welding generally is not taken for using in the box-type module building as connections between building modules. Therefore, bolted connection pairs is the quickest and simplest way to connect box-type module buildings. The top surface of the building module is the most suitable for operating space of the bolted connection pairs connecting the upper and lower building modules, considering that the top surface of the building module will not be blocked by pre-installed objects, and that people will be allowed to get aboard it during the installation of the building module and no scaffolding will be required.

[0004] At present, although it is possible to complete the connection operation of the bolted connection pairs for upper and lower building modules from the top surface of the building module, there are some disadvantages such as use of non-standard parts and the failure of the bolted connection caused by the deviations between stacked upper and lower boxes.

[0005] Specifically, there are large numbers of parts in bolted connection pairs. Internal and external threaded bolts will be used in order to ensure the convenience of bolted connection.

The internal and external threaded bolts are non-standard bolt fasteners with both internal and external surfaces threaded, which needs to be customized, so they are not suitable for the occasions required to conform standards and specifications. In addition, during installation of stacking upper and lower building modules, the top surface of the lower building module shall be provided with an opening to be bolted, wherein the upper end face of the opening is flush with the top surface; when the upper layer building module is placed downward, it is difficult for the bolt fasteners of the upper layer building module to be accurately inserted into the opening, such that deviations between the upper and lower building modules readily occur, and eventually the assembly of bolts cannot be successfully connected and the connection thereby fails.

DETAILED DESCRIPTION

[0048] Exemplary embodiments embodying 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 drawings therein are essentially used for illustrating rather than limiting this invention.

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

[0050] The present invention provides a building module and connecting structure thereof The connecting structure can be applied to adjacent building modules for the connections and securing between the upper and lower ones, as well as the connections and securing between respective building module and load-bearing member. It has the advantages of quick and stable connection and accurate positioning. Among them, the load-bearing member includes structural parts used for load bearing, such as foundation, floor, post, and wall.

First Embodiment of Building Module [0051] The building module comprises a post, a plurality of transverse members, a plurality of side rails, and a connecting structure. The post is arranged vertically. The transverse members and side rails are arranged horizontally. A plurality of posts, a plurality of transverse members and a plurality of side rails are connected to form a frame, such that the building module is frame shaped. In this embodiment, each of the number of posts, the number of transverse members, and the number of side rails is four. The connecting structure is arranged corresponding to the post to connect the building module with a load-bearing member or said building module with a building module below it.

[0052] Referring to FIG. 1, FIG. 2, and FIG. 3, the post 1 comprises a tubular post body 11, a top plate 12 disposed on the top of the post body 11, and a bottom plate 13 disposed at the bottom of the post 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.

[0053] In other embodiments, the post 1 has a tubular shape with openings at both its top and the bottom portions, wherein the top portion is provided with a top corner fitting and the bottom portion is provided with a bottom corner fitting. The top corner fitting has a corner-fitting hole on its top wall which constitutes the mounting hole 121, and the bottom corner fitting has a corner-fitting hole on its bottom wall which constitutes the positioning hole 131.

[0054] Wherein, the mounting hole 121 is an elongated hole, and either end thereof in the lengthwise direction is transitioned in arcs. The positioning hole 131 is a circular hole.

[0055] The connecting structure 2 comprises a connecting cone 21, a fastener 22, and a fixing member 23. These components cooperate to create connections between the building module and a building module or the building module and the foundations.

[0056] Referring to FIG. 4, FIG. 5, and FIG. 6, the connecting cone 21 comprises a cone head 211, a rotating member 212, a restriction member 213, and a clamping piece 215 arranged in sequence.

[0057] The cone head 211 is used to fit with the positioning hole 131 of another building module to create quick positioning of the building module and another building module. The cone head 211 is generally conical, wherein the outline of the cone head 211 is arc-shaped, and the dimension of the cross-section of the cone head 211 gradually increases along the direction toward the rotating member 212, i.e., in the direction from top to bottom.

[0058] Further, the cross-sectional dimension of a portion of the cone head 211 near the rotating member 212 is larger than the dimension of the mounting hole, such that the cone head 211 abuts against the top of the structure below the building module.

100591 A guide chamfer 2111 is disposed on the top of the cone head 211, wherein the dimension of the inner diameter of the guide chamfer 2111 tends to increase in the direction facing away from the cone head, that is, gradually increases from top to bottom. It is for the purpose that the tapered design of the cone head 211 along with the structural design of the guide chamfer 2111 enable playing the role of guiding and positioning, facilitating quick positioning of the fastener 22 and improving the efficiency and accuracy of connections.

[0060] Further, the cone head 211 is provided with a through pin hole 2112. The axis of the pin hole 2112 is parallel to the axis of the cone head 211, that is, the pin hole 2112 is through up and down. In this embodiment, the number of the pin hole 2112 is two, and they are located on respective one of sides with respect to the axis of the cone head 211.

[0061] Referring to FIG. 6, at the bottom of the cone head 211 is provided a connecting rod 214, wherein the connecting rod 214 is rod-shaped, that is, the cross section of the connecting rod 214 is circular. The axis of the connecting rod 214 and the axis of the cone head 211 are in the common line, and the diameter of the connecting rod 214 is smaller than the size of the bottom of the cone head 211.

[0062] In this embodiment, the connecting rod 214 and the cone head 211 are integrally formed. In other embodiments, the connecting rod 214 may also be welded to the cone head 211.

[0063] The rotating member 212 is rotatably connected with the cone head 211.

Specifically, the rotating member 212 is provided with a via hole for the connecting rod 214 passing therethrough, that is, the rotating member 212 is sleeved over the outer periphery of the connecting rod 214 and disposed below the cone head 211, such that the rotatable connection between the rotating member 212 and the cone head 211 is created.

[0064] Specifically, the via hole is circular, and its inner diameter is slightly larger than the outer diameter of the connecting rod 214, so that the rotating member 212 is rotatable relative to the cone head 211.

[0065] Referring to FIG. 7, the rotating member 212 is in the form of an elongated plate with smooth transitions at either end in the lengthwise direction. The rotating member 212 conforms to the mounting hole 121 and can pass through the mounting hole 121. The thickness of the rotating member 212 is the same as the thickness of the circumferential wall of the mounting hole 121.

[0066] The rotating member 212 is further provided with a mating hole 2121 arranged corresponding to the pin hole 2112 on the cone head 211. In this embodiment, the number of the pin hole 2112 is two, and therefore the number of the mating hole 2121 is two. The two mating holes 2121 are arranged at intervals along the lengthwise direction of the rotating member 212 and are arranged on respective one of sides with respect to the via hole.

[0067] When the rotating member 212 rotates to bring the mating hole 2121 and the pin hole 2112 being on the common line, the pin shaft may be inserted into both the pin hole 2112 and the mating hole 2121 to restrict the rotation between the rotating member 212 and the cone head 211. In this embodiment, when the lengthwise direction of the rotating member 212 and the lengthwise direction of the restriction member 213 are at an angle of 900, that is, when the lengthwise direction of the rotating member 212 is parallel to the widthwise direction of the restriction member 213, the mating hole 2121 and the pin hole 2112 are located on the common line and are communicated with each other.

[0068] Specifically, the height of the pin shaft is greater than the height of the rotating member 212, and the pin shaft is supported by the restriction member 213 beneath the rotating member 212. The pin shaft is therefore stuck in the mating hole 2121 and the pin hole 2112, thereby restricting the rotation between the rotating member 212 and the cone head 211. The height of the pin shaft can be greater than the sum of the height of the cone head 211 and the height of the rotating member 212, so as to facilitate inserting or removing the pin shaft. The pin shaft can further be provided with a cavity inside, wherein the cavity has an inner circumferential wall with internal threads, and a bolt with external threads can create threaded connections between the bolt and the pin shaft, thereby facilitating inserting or removing the pin shaft by the bolt.

[0069] The restriction member 213 is fixedly connected with the cone head 211 such that the restriction member 213 are also rotatably connected with the rotating member 212. That is, when the cone head 211 rotates, the restriction member 213 is driven to rotate, allowing ratable connections between each of the cone head 211 and the restriction member 213 with the rotating member 212. Specifically, the restriction member 213 is connected to the other end of the connecting rod 214 relative to the cone head 211, i.e., the bottom end of the connecting rod 214.

[0070] The restriction member 213 is in the form of an elongated plate with smooth transitions at either end in the lengthwise direction. In this embodiment, the size of the restriction member 213 is the same as that of the rotating member 212.

[0071] The length of the restriction member 213 is smaller than the length of the mounting hole 121, and the length of the restriction member 213 is greater than the width of the mounting hole 121. Therefore, when the lengthwise direction of the restriction member 213 is parallel to the lengthwise direction of the mounting hole 121, the restriction member 213 can pass through the mounting hole 121; when the cone head 211 is rotated such that the widthwise direction of the restriction member 213 is parallel to the lengthwise direction of the mounting hole 121, the restriction member 213 cannot pass through the mounting hole 121, and here the restriction member 213 is located below the top plate 12 and abuts against the top plate 12.

[0072] The connecting cone 21 has an inner cavity passing therethrough from the top of the cone head 211 to the bottom of the restriction member 213. The axis of the inner cavity and the axis of the cone head 211 are in the common line.

[0073] In combination with FIG. 4 and FIG. 8, the clamping piece 215 comprises a bottom wall 2151 and a plurality of side walls 2152. The bottom wall 2151 is disposed at the further end facing away from the cone head 211, and is provided with a through hole for the screw shaft 221 passing therethrough. A clamping trough is surrounded and formed by the bottom wall 2151 and the plurality of side walls 2152. In this embodiment, the bottom wall 2151 has a hexagonal shape, and the number of the side walls 2152 is three, which are arranged at intervals.

[0074] Referring to FIGS. 9 and 10, the fastener 22 is located inside the post 1 and protrudes downwardly from the post 1. The fastener 22 specifically includes a screw shaft 221, a baffle plate 222 disposed on the top of the screw shaft 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.

[0075] The nut 225 conforms to the screw shaft 22L The cross section of the nut 225 has a hexagonal shape, which is mated with the clamping trough.

[0076] The screw shaft 221 can be inserted into the inner cavity of the connecting cone 21 and connected to the connecting cone 21. An external thread is disposed outside the screw shaft 221, and an internal thread is disposed inside the nut 225, such that the screw shaft 221 and the nut 225 are threaded.

[0077] The fastener 22 and the connecting cone 21 are connected by threaded connections between the screw shaft 221 with the nut 225. Specifically, the nut 225 is clamped in the clamping trough of the connecting cone 21. The screw shaft 221 passes through the inner cavity of the connecting cone 21 and is threaded with the nut 225 and passes through the through hole on the bottom wall 2151. The nut 225 being clamped in the clamping trough, avoids the situation where it is difficult for the screw shaft 221 and the nut 225 to be securely locked during the installation, and ensures the connection strength. The connecting pipe 223 is hollow inside, and the operating plate 224 is provided with an operation hole for operation. In this embodiment, the operation hole is a hexagonal through-hole for the operation of inserting the L-shaped hexagon wrench and tightening operation by an operator.

[0078] Further, the operating plate 224 is also provided with a bottom-end hook 226. An top-end hook 14 is disposed on the top of the interior of the post I. The bottom-end hook 226 can be hung on the top-end hook 14 to suspend the fastener 22 inside the post 1, thereby facilitating accommodating of the fastener 22. Before installation, the fastener 22 is suspended over the inner wall of the post 1. During assembly, the fastener 22 is ready for use by the operator reaching into the post 1 and taking it off from the top-end hook 14.

[0079] Referring to FIG. 11, the fixing member 23 is fixed to the bottom of the interior of the post 1. Specifically, the fixing member 23 comprises a fixing tube 232 standing at the bottom in the post 1 and a fixing plate 231 fixed on the top of the fixing tube 232. The fixing pipe 231 is provided with a via hole for the screw shaft 221 passing therethrough and restricting the baffle plate 222 from passing therethrough.

[0080] In this embodiment, the fixing tube 231 is standing on the bottom plate 13 of the post I. 100811 In order to further enable those skilled in the art to specifically understand how the connecting structure 2 provided in this embodiment creates the connections and fixations between the building module and a building module, the specific connection process will be described below.

[0082] For the sake of convenience of description, the building module on the lower layer is assigned as the lower building module, and the building module on the upper layer is assigned as the upper building module.

[0083] Si: Placing the lower building module.

[0084] Specifically, the lower building module is horizontally placed in a predetermined installation spot. The lower building module can utilize the building module in the present application or the building module in the related art. In this case, the building module has a corner fitting, and the corner-fitting hole constitutes the mounting hole 121.

[0085] 52: Placing the connecting cone 21 of the connecting structure 2 of the upper building module at the lower building.

[0086] Specifically, the upper building module utilizes the building module in the present application and comprises a connecting structure 2. The rotating member 212 and the restriction member 213 of the connecting cone 21 are rotated to bring their lengthwise directions conforms to each other, and the connecting cone 21 are placed from top to bottom into the mounting hole 121 of the lower building module, such that the rotating member 212 and the top plate 12 are located at the same height. Then, the cone head 211 is rotated by an angle of 900, so that the widthwise direction of the restriction member 213 is parallel to the lengthwise direction of the mounting hole 121, and the restriction member 213 and the top plate 12 are thereby locked against each other.

[0087] S3: Placing the upper building module such that the upper building module is stacked on the top of the lower building module.

[0088] Specifically, the cone head 211 of the connecting cone 21 passes through the positioning hole 131 of the upper building module, so as to create the quick positioning of the upper building module and the lower building module.

[0089] S4: Connecting the fastener 22 to the connecting cone 21 to create the connection between the upper building module and the lower building module.

[0090] Specifically, the screw shaft 221 of the fastener 22 is inserted from the top of the connecting cone 21, and the screw shaft 221 is rotated using cooperation between the operation hole with the hexagonal wrench tool, so that the external thread of the screw shaft 221 mates with the internal thread on the inner peripheral wall of the inner cavity to establish threaded connection.
