[0081] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0082] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0083] Herein, ordinal numbers such as “first” and “second” cited in this application are merely identifiers and do not include any other meanings, such as a specific order or the like.

[0084] In order to thoroughly understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also include other implementations.

[0085] The present application provides a concrete modular building. The concrete modular building is formed by pouring concrete on a steel structure. The concrete modular building is constructed as a substantially rectangular parallelepiped structure. The size of the concrete modular building can be substantially the same as the size of a standard container. The top of the steel structure has a steel top frame 120. The corners of the steel top frame 120 are provided with top corner connection boxes 124. In this way, the concrete modular building can be hoisted through the top corner connection boxes 124, so that there is no need to vertically hoist the concrete modular building, and the operation of hoisting the concrete modular building is convenient.

[0086] Please refer to Figures 1 to 13 The concrete modular building includes a box body 100 and a top cover 160. The top of the box body 100 has a top opening 101. Therefore, the top opening 101 of the box body 100 can reduce the weight of the box body 100 and facilitate hoisting.

[0087] like Figures 1 to 6 As shown, the box body 100 includes a concrete body 110. The concrete body 110 includes a vertical wall 113 and a bottom wall. The vertical wall 113 includes a side wall and an end wall. The side wall, the end wall and the bottom wall form a substantially rectangular parallelepiped structure.

[0088] Optionally, one end wall is provided with a doorway for setting a box door, and the other end wall is provided with a window for setting a window for ventilation, thereby further reducing the weight of the box body 100.

[0089] like Figures 1 to 9 As shown, the box body 100 also includes a steel top frame 120. The steel top frame 120 is made of metal. The steel top frame 120 is constructed as a circumferentially closed annular structure. The steel top frame 120 includes a top beam 121 and a top corner connection box 124. The top beam 121 can be rectangular steel. The top beam 121 includes a top side beam 123 and a top end beam 122. The length direction of the top side beam 123 is parallel to the length direction of the box body 100. The length direction of the top end beam 122 is parallel to the width direction of the box body 100. The ends of the top end beam 122 and the top side beam 123 are connected to form a roughly rectangular frame. The top end beam 122 is located at the top end of the end wall. The top side beam 123 is located at the top end of the side wall. Along the length direction of the box body 100, the top end beam 122 is located at the end of the box body 100. Along the width direction of the box body 100, the top side beam 123 is located at the side of the box body 100.

[0090] like Figure 3 ,as well as Figures 8 to 13 As shown, a top corner connection box 124 is provided at the corner of the steel top frame 120. The top side beam 123 and the top end beam 122 are connected by the top corner connection box 124. The top corner connection box 124 has a connection hole. Specifically, a top hole 130 (an example of a connection hole) is provided at the top of the top corner connection box 124. Along the length direction of the box body 100, the outer end surface of the top corner connection box 124 away from the center of the steel top frame 120 has an end hole 134 (an example of a connection hole). Along the width direction of the box body 100, the outer side surface of the top corner connection box 124 away from the center of the steel top frame 120 has a side hole 132 (an example of a connection hole). The connection hole can be roughly the same as the setting of the corner hole of the corner piece of the existing container, so as to be able to connect the twist lock, and the structure of the connection corner piece of the ship and vehicle for transporting concrete modular buildings. The box body 100 can also be tied through the side hole 132 and the end hole 134. It can be understood that in an embodiment not shown, the connection hole may also be different from the corner fitting hole of the existing container corner fitting.

[0091] The steel top frame 120 is connected to the top of the concrete body 110 (top of the vertical wall 113). At this time, the top beam 122 and the top side beam 123 surround the top opening 101. The top cover 160 is connected to the top of the box body 100 to cover the top opening 101.

[0092] In this embodiment, the provision of the steel top frame 120 can increase the strength of the top of the box body 100. The top corner connection boxes 124 are provided at the corners of the steel top frame 120. The hanging points can be set through the top corner connection boxes 124, so that the box body 100 can be hoisted by the hoisting ropes 190, which can avoid cracking of the box body, and further avoid cracking and leakage, and avoid cracking affecting the finished decoration surface of the module; in this way, there is no need to vertically hoist the box body 100; the provision of the top opening 101 can reduce the weight of the concrete modular building.

[0093] Alternatively, if Figure 7As shown, the vertical wall 113 has a main body 111 and a positioning portion 112. The positioning portion 112 is located above the main body 111. The positioning portion 112 is connected to the top of the main body 111. The inner side surface of the positioning portion 112 close to the center of the box body 100 and the inner side surface of the main body 111 close to the center of the box body 100 are roughly flush. The top beam 121 is located above the main body 111. The top beam 121 is overlapped to the top surface of the main body 111. The thickness dimension of the main body 111 is greater than the thickness dimension of the positioning portion 112. The top beam 121 is located on the outer side of the positioning portion 112 away from the center of the steel top frame 120 in the horizontal direction. In this way, the steel top frame 120 is embedded in the concrete body 110. Along the thickness direction of the main body 111, the size of the whole formed by the top beam 121 and the positioning portion 112 is roughly equal to the thickness dimension of the main body 111. As a result, the contact area between the top beam 121 and the concrete body 110 is large, and the connection strength is high.

[0094] Optionally, the top cover 160 is a metal piece. Thus, the top cover 160 is light in weight and convenient for hoisting. In addition, the top cover 160 has great strength.

[0095] Alternatively, if Figure 7 As shown, the top of the outer side surface of the main body 111 away from the center of the box body 100 is recessed inward (toward the center of the box body 100 in the horizontal direction) to form an avoidance gap 114. The edge 161 of the top cover 160 has a mounting groove 162 with an opening facing downward. When the top cover 160 covers the top opening 101, the top beam 121 and the positioning portion 112 are both located in the mounting groove 162. When the top cover 160 covers the top opening 101, the outer side surface of the mounting groove 162 away from the center of the box body 100 in the horizontal direction is located in the avoidance gap 114. The outer side surface of the mounting groove 162 and the outer side surface of the main body 111 are arranged at intervals.

[0096] Please continue to refer to Figure 7 The concrete modular building further includes a top cover fastener 184. For example, the top cover fastener 184 may be a self-tapping screw. When the top cover 160 covers the top opening 101, the outer side wall of the mounting groove 162 away from the center of the box body 100 may be connected to the top beam 121 through the top cover fastener 184. At this time, the head of the top cover fastener 184 is completely located in the avoidance gap 114. Thus, the concrete modular building is conveniently transported.

[0097] It can be understood that in an embodiment not shown, the top cover fasteners can be bolts or expansion bolts.

[0098] Furthermore, the edge 161 of the top cover 160 is a U-shaped piece with an opening facing downward to form a mounting groove 162. Thus, the structure of the top cover 160 is simple.

[0099] Alternatively, if Figure 3 , Figure 8 and Fig.13 As shown, the steel top frame 120 also includes a top intermediate connection box 125. The shape of the top intermediate connection box 125 is roughly the same as the top corner fittings of the existing container. The top intermediate connection box 125 is connected to the top side beam 123. Along the length direction of the box body 100, the top intermediate connection box 125 is located on the inner side of the top corner connection box 124 close to the center of the steel top frame 120. Along the length direction of the box body 100, the top intermediate connection box 125 and the top corner connection box 124 are arranged at intervals. The top intermediate connection box 125 has a connection hole. Specifically, the top of the top intermediate connection box 125 has a top hole 130. Along the width direction of the box body 100, the outer side surface of the top intermediate connection box 125 away from the center of the steel top frame 120 has a side hole 132. Therefore, the top hole 130 of the top intermediate connection box 125 can be used as a hanging point for hanging the box body 100. In this way, it is more convenient to hang the box body 100. In addition, the side holes 132 of the top middle connection box 125 can also be used for binding.

[0100] Optionally, refer to Figure 3 The box body 100 further includes a steel bottom frame 140. The steel bottom frame 140 is a metal part. The steel bottom frame 140 is constructed as a circumferentially closed annular structure. The steel bottom frame 140 includes a bottom beam 141 and a bottom corner connection box 144. The bottom beam 141 includes a bottom side beam 143 and a bottom end beam 142. The length direction of the bottom side beam 143 is parallel to the length direction of the box body 100. The length direction of the bottom end beam 142 is parallel to the width direction of the box body 100. The ends of the bottom end beam 142 and the bottom side beam 143 are connected to form a substantially rectangular frame. The bottom end beam 142 is located at the bottom end of the end wall. The bottom side beam 143 is located at the bottom end of the side wall. The steel bottom frame 140 is connected to the bottom end of the concrete body 110. In this way, the steel bottom frame 140 is embedded in the concrete body 110. The provision of the steel bottom frame 140 can increase the strength of the bottom end of the box body 100.

[0101] like Figure 3 , Figures 10 to 12 As shown, a bottom corner connection box 144 is provided at the corner of the steel bottom frame 140. The bottom side beam 143 and the bottom end beam 142 are connected by the bottom corner connection box 144. The bottom corner connection box 144 has a connection hole. Specifically, a bottom hole 131 (an example of a connection hole) is provided at the bottom of the bottom corner connection box 144. Along the length direction of the box body 100, the outer end surface of the bottom corner connection box 144 away from the center of the steel bottom frame 140 has an end hole 134 (an example of a connection hole). Along the width direction of the box body 100, the outer side surface of the bottom corner connection box 144 away from the center of the steel bottom frame 140 has a side hole 132 (an example of a connection hole).

[0102] Thus, when stacking two boxes 100, the bottom surface of the bottom corner connection box 144 of the upper box 100 is overlapped (for example, stacked on by the connecting plate 182 and the adjustment plate 181 described later) with the top surface of the top corner connection box 124 of the lower box 100 so as to be stacked through the bottom corner connection box 144 and the top corner connection box 124.

[0103] Alternatively, if Figure 3 and Fig.13 As shown, the steel bottom frame 140 also includes a bottom intermediate connection box 145. The shape of the bottom intermediate connection box 145 is roughly the same as the shape of the bottom corner piece of the existing container. The bottom intermediate connection box 145 is connected to the bottom side beam 143. Along the length direction of the box body 100, the bottom intermediate connection box 145 is located on the inner side of the bottom corner connection box 144 close to the center of the steel bottom frame 140. Along the length direction of the box body 100, the bottom intermediate connection box 145 and the bottom corner connection box 144 are arranged at intervals. The bottom intermediate connection box 145 has a connection hole. Specifically, the bottom of the bottom intermediate connection box 145 has a bottom hole 131. Along the width direction of the box body 100, the outer side surface of the bottom intermediate connection box 145 away from the center of the steel bottom frame 140 has a side hole 132. Therefore, the side hole 132 of the bottom intermediate connection box 145 can also be used for binding.

[0104] When stacking two boxes 100, the bottom surface of the bottom intermediate connection box 145 of the upper box 100 is overlapped (for example, stacked on through the connecting plate 182 and the adjustment plate 181 described later) with the top surface of the top intermediate connection box 125 of the lower box 100 so as to be stacked through the bottom intermediate connection box 145 and the top intermediate connection box 125.

[0105] Optionally, return Figure 3 The steel bottom frame 140 further includes a bottom cross beam 146. The length direction of the bottom cross beam 146 is parallel to the width direction of the box body 100. Along the length direction of the box body 100, the bottom cross beam 146 is located between the two bottom end beams 142. Along the width direction of the box body 100, the bottom cross beam 146 is located between the two bottom side beams 143. The end of the bottom cross beam 146 is connected to the bottom middle connection box 145. Thus, the strength of the bottom end of the box body 100 can be increased.

[0106] Optionally, please continue to refer to Figure 3 , the box 100 further includes a column 150. The column 150 is a metal piece. The length direction of the column 150 is parallel to the height direction of the box 100. Along the length direction of the box 100, the column 150 is located between the two ends of the box 100. The bottom end of the column 150 is connected to the bottom intermediate connection box 145. The top end of the column 150 is connected to the top intermediate connection box 125. In this way, the strength of the box 100 can be increased.

[0107] Alternatively, if Figure 3As shown, the box 100 further includes a corner post 151. The corner post 151 is a metal piece. The length direction of the corner post 151 is parallel to the height direction of the box 100. The top end of the corner post 151 is connected to the top corner connection box 124. The bottom end of the corner post 151 is connected to the bottom corner connection box 144. The corner post 151 is spaced apart from the column 150. Thus, the strength of the box 100 can be increased.

[0108] It should be noted that the steel structure includes corner columns 151 , columns 150 , a steel bottom frame 140 and a steel top frame 120 .

[0109] like Figures 9 to 11 As shown, the top of the top corner connection box 124 also has a top through hole 135. The bottom of the bottom corner connection box 144 also has a bottom through hole 136. The concrete modular building also includes a stacking fastener 180. The stacking fastener 180 is used to penetrate the top through hole 135 and the bottom through hole 136, and then connect the nut to connect the two stacked boxes 100. Thereby, the connection strength of the two stacked boxes 100 can be increased.

[0110] Furthermore, if Fig. 9 and Fig.10 As shown, the top corner connection box 124 has a top corner fitting 126 and a top connection part 127. The shape of the top corner fitting 126 is substantially the same as that of the top corner fitting of the existing container. The top corner fitting 126 has a connection hole. The top connection part 127 has a top through hole 135. Along the width direction of the box body 100, the top connection part 127 is located on the inner side of the top corner fitting 126 close to the center of the box body 100. The top corner fitting 126 and the top connection part 127 are connected. The top surface of the top corner fitting 126 and the top surface of the top connection part 127 are substantially flush. Along the length direction of the box body 100, the outer side surface of the top connection part 127 away from the center of the box body 100 has a top operation hole 137 connected to the top through hole 135. The top operation hole 137 is spaced apart from the end hole 134. Thus, the stacking fastener 180 and the nut can be operated through the top operation hole 137. In addition, the arrangement of the top corner piece 126 and the top connecting portion 127 increases the strength of the top corner connecting box 124.

[0111] like Figure 3 and Fig.10As shown, the bottom corner connection box 144 has a bottom corner fitting portion 148 and a bottom connecting portion 149. The shape of the bottom corner fitting portion 148 is substantially the same as that of the bottom corner fitting of the existing container. The bottom corner fitting portion 148 has a connecting hole. The bottom connecting portion 149 has a bottom through hole 136. Along the width direction of the box body 100, the bottom connecting portion 149 is located on the inner side of the bottom corner fitting portion 148 close to the center of the box body 100. The bottom corner fitting portion 148 and the bottom connecting portion 149 are connected. The bottom surface of the bottom corner fitting portion 148 is substantially flush with the bottom surface of the bottom connecting portion 149. Along the length direction of the box body 100, the outer side surface of the bottom connecting portion 149 away from the center of the box body 100 has a bottom operation hole 133 connected to the bottom through hole 136. The bottom operation hole 133 is spaced apart from the end hole 134. Thus, the stacking fastener 180 and the nut can be operated through the bottom operation hole 133. In addition, the arrangement of the bottom corner piece 148 and the bottom connecting portion 149 increases the strength of the bottom corner connecting box 144.

[0112] Optionally, refer to Figure 6 ,as well as Figures 8 to 13 The concrete modular building further includes a connector 170. The connector 170 is a metal part. The connector 170 extends along the height direction of the box 100. When two boxes 100 are stacked, part of the connector 170 is inserted into the bottom hole 131 of the bottom intermediate connection box 145 of the box 100 located above and the top hole 130 of the top intermediate connection box 125 of the box 100 located below, thereby extending into the bottom intermediate connection box 145 and the top intermediate connection box 125, so as to connect the bottom intermediate connection box 145 and the top intermediate connection box 125, thereby connecting the two boxes 100. When two boxes 100 are stacked, another part of the connecting member 170 is passed through the bottom hole 131 of the bottom corner connecting box 144 of the box 100 located at the top, and the top hole 130 of the top corner connecting box 124 of the box 100 located at the bottom, so as to extend into the bottom corner connecting box 144 and the top corner connecting box 124, so as to connect the bottom corner connecting box 144 and the top corner connecting box 124, thereby connecting the two boxes 100. As a result, the connection strength of the stacked boxes 100 is large.

[0113] like Figure 8 and Fig. 9 As shown, the top of the connecting member 170 is configured as a tapered structure 175 that is small at the top and large at the bottom. In this way, when stacking two boxes 100, the connecting member 170 is extended into the top hole 130 of the box 100 located below. At this time, the connecting member 170 extends to the top of the box 100 located below. Then, the box 100 located above is hoisted to the connecting member 170, so that the connecting member 170 extends into the bottom hole 131 of the box 100 located above. At this time, the tapered structure 175 can guide the movement of the box 100 located above. In this way, it is convenient to install the two stacked boxes 100.

[0114] Optionally, please continue to refer to Figure 8 and Fig. 9 The side of the connecting member 170 extends horizontally to form a limiting portion 174. When two boxes 100 are stacked, the limiting portion 174 can overlap the edge of the top hole 130 of the box 100 located below to limit the position of the connecting member 170. This facilitates installation.

[0115] Alternatively, if Figure 8 and Fig. 9 As shown, the connecting member 170 has a first plate 171, a second plate 172 and a third plate 173. The second plate 172 and the third plate 173 are arranged at intervals. The plane where the second plate 172 is located is parallel to the plane where the third plate 173 is located. The plane where the second plate 172 is located is perpendicular to the plane where the first plate 171 is located. Specifically, the plane where the first plate 171 is located is perpendicular to the width direction of the box 100. The plane where the second plate 172 is located is perpendicular to the length direction of the box 100. Along the length direction of the box 100, the second plate 172 and the third plate 173 are arranged at intervals. The second plate 172 and the third plate 173 are both connected to the first plate 171. Along the width direction of the box 100, the second plate 172 and the second plate 172 are arranged on both sides of the first plate 171. The second plate 172 and the third plate 173 are both provided with a limiting portion 174. As a result, the strength of the connecting member 170 is large.

[0116] Furthermore, the connection member 170 is a casting, so that the connection member 170 has a high strength.

[0117] Alternatively, if Fig.10 and Fig.12 As shown, the concrete modular building further includes a connecting plate 182 and an adjusting plate 181. The adjusting plate 181 is a flat plate. The adjusting plate 181 can be disposed between two stacked boxes 100 to adjust the angle between the plane where the bottom wall of the box 100 located above is located and the horizontal plane, so that the plane where the bottom wall is located is as parallel to the horizontal plane as possible. For example, the adjusting plate 181 is disposed between the top surface of the top corner connection box 124 and the bottom surface of the bottom corner connection box 144. The adjusting plate 181 can also be disposed between the top surface of the top intermediate connection box 125 and the bottom surface of the bottom intermediate connection box 145.

[0118] The connecting plate 182 is a flat plate. The connecting plate 182 is provided with holes for avoiding the connecting member 170 and the stacking fastener 180. The thickness of the connecting plate 182 is greater than the height dimension of the limiting portion 174. The connecting plate 182 can be arranged between two stacked boxes 100 to support the box 100 located above. For example, the connecting plate 182 is arranged between the top surface of the top corner connection box 124 and the bottom surface of the bottom corner connection box 144. The connecting plate 182 can also be arranged between the top surface of the top intermediate connection box 125 and the bottom surface of the bottom intermediate connection box 145.

[0119] Optionally, when the top cover 160 covers the top opening 101, the top surface of the top corner connection box 124 and the top surface of the top middle connection box 125 are both located above the top surface of the edge 161. The bottom surface of the bottom corner connection box 144 and the bottom surface of the bottom middle connection box 145 are both located below the bottom surface of the concrete body 110. In this way, the concrete body 110 can be protected, and the stacking and fixing of the concrete modular building are convenient.

[0120] Second embodiment

[0121] like Fig.14 and Fig.15 As shown, in the second embodiment, when the top cover covers the top opening, the edge 261 of the top cover overlaps and is connected to the top surface of the top beam 221. At this time, the edge 261 of the top cover can be welded to the top surface of the top beam 221. The outer side surface of the top beam 221 away from the center of the steel top frame in the horizontal direction is roughly flush with the outer side surface of the main body. The edge 261 does not have a mounting groove. Therefore, the transportation of the concrete modular building is convenient.

[0122] The steel bottom frame 240 does not have bottom crossbeams and columns.

[0123] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0124] Third embodiment

[0125] In the third embodiment, if Fig.16 As shown, the steel base frame 340 has no columns.

[0126] The other configurations of the third embodiment are substantially the same as those of the first embodiment and will not be described in detail herein.

[0127] Fourth embodiment

[0128] In the fourth embodiment, if Fig.17 As shown, the steel bottom frame 440 does not have a bottom cross member.

[0129] The other configurations of the fourth embodiment are substantially the same as those of the first embodiment and will not be described in detail here.

[0130] Fifth embodiment

[0131] In the fifth embodiment, if Figures 18 to 20 As shown, the top cover 560 is an integrated structure formed by welding steel parts. Therefore, the top cover 560 has great strength.

[0132] like Figures 18 to 20 As shown, the two side walls of the vertical wall 513 are connected with the two end walls to form a tetrahedron structure. The tetrahedron structure is a circumferentially closed structure. The bottom end of the tetrahedron structure has a bottom opening 516.

[0133] The concrete modular building further comprises a bottom nesting 517, a bottom fastener 518 and a bottom connecting member 519. The bottom nesting 517 is a sleeve-shaped structure with internal threads. The bottom wall 515 is connected to the vertical wall 513 through the bottom fastener 518 to cover the bottom opening 516.

[0134] Specifically, the bottom inner nest 517 is embedded in the bottom end of the vertical wall 513. The bottom connector 519 can be a sheet metal part. For example, the bottom connector 519 is an angle steel. One end of the bottom connector 519 is connected to the bottom wall 515. For example, one end of the bottom connector 519 is connected to the bottom wall 515 by a fastener (bolt). The other end of the bottom connector 519 is attached to the bottom end of the vertical wall 513. The bottom fastener 518 can be a bolt. After the bottom fastener 518 is inserted into the other end of the bottom connector 519, it is threadedly connected to the bottom inner nest 517 to connect the bottom wall 515 and the vertical wall 513. Thus, the box body is formed by connecting the vertical wall 513 and the bottom wall 515, and the weight of the vertical wall 513 and the bottom wall 515 is small, which is convenient for loading and unloading the box body.

[0135] Optionally, the bottom wall 515 may be a steel structure frame. The steel structure frame is a common steel profile. In an embodiment not shown, the bottom wall 515 may be a concrete structure cast in the steel structure frame by concrete, or the bottom wall 515 may be light steel. The weight of light steel is less than that of a common steel profile.

[0136] The other configurations of the fifth embodiment are substantially the same as those of the first embodiment and will not be described in detail here.
