Description

[0002] At present, box-type modular buildings generally have two structural forms of steel structure and concrete. The characteristics of box-type modular buildings are high degree of prefabrication, small workload on the construction site and short project period, which also restricts the connection construction space, construction efficiency and connection reliability between building modules. As the manufacturing technology of prefabricated building structures becomes more mature, people have higher requirements for the prefabrication degree of building modules, thus requiring smaller connection construction space, higher construction efficiency and connection reliability for the connection structure between building modules.

[0003] In the prior art, whether it is steel structure or concrete building modules, their connection structures are too complicated and require a large construction space, which restricts the pre-installation degree of the building modules and increases the reinforcement materials of the building modules for the connection structure.

[0100] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.

[0101] The present application provides a modular building.

[0102] See also Figure 1 , the modular building 100 includes a connection assembly 130. The connection assembly 130 includes a first connection member 131 and a second connection member 132. Specifically, the first connection member 131 is arranged along the vertical direction DH, and the first connection member 131 has a first contact surface inside, and the first contact surface is inclined relative to the vertical direction DH and the first horizontal direction D1. The second connection member 132 is arranged along the first horizontal direction D1 and connected to the first connection member 131, and the second connection member 132 has a second contact surface 132a suitable for the first contact surface. The second connection member 132 at least partially extends to the inside of the first connection member 131, so that the second contact surface 132a abuts against the first contact surface.

[0103] According to the connection component 130 of the present solution, by setting an inclined contact surface, it is easy to form a pre-tightening force between the first connection member 131 and the second connection member 132; and in the process of fixing and connecting, the space between the objects connected to each other can be reduced, and the difficulty of operation is reduced.

[0104] It can be understood that, since the second contact surface 132a is adapted to the first contact surface and abuts against the first contact surface, the second contact surface 132a is also inclined relative to the vertical direction DH and the first horizontal direction D1.

[0105] Furthermore, the modular building 100 further includes an upper module 110 and a lower module 120, wherein the lower module 120 is located below the upper module 110. The connecting assembly 130 is located between the upper module 110 and the lower module 120, and the connecting assembly 130 is connected to the upper module 110 and the lower module 120. Figure 1 In the embodiment, the upper module 110 and the lower module 120 both include a column assembly 140, and the connecting assembly 130 is located between the column assemblies 140 adjacent to each other along the vertical direction DH. Figure 1 and Figure 2, the column assembly 140 has a first connection port 144a and a second connection port 141b that are connected to the outside. The first connection port 144a faces the vertical direction DH, and the second connection port 141b faces the first horizontal direction D1. The first connection member 131 extends to the inside of the column assembly 140 via the first connection port 144a, and the second connection member 132 extends to the inside of the column assembly 140 via the second connection port 141b. The upper module 110 / lower module 120 includes a column 141, a first module beam 142, a second module beam 143 and a column connecting plate 144. The column 141 is arranged along the vertical direction DH and is configured as a tubular member, such as a square tube. The column 141 is provided with a second connection port 141b that is connected to the outside. The column connecting plate 144 is connected to the top and bottom of the column 141 to close the column 141 in the vertical direction DH. The column connecting plate 144 has a first connecting port 144a, and the first connecting port 144a penetrates the column connecting plate 144 along the vertical direction DH. The first module beam 142 is arranged along the first horizontal direction D1 and connected to the column 141, and the second module beam 143 is arranged along the second horizontal direction D2 perpendicular to the first horizontal direction D1 and connected to the column 141. It should be noted that the above-mentioned column assembly 140 is generally applicable to the use of steel structure modules. Alternatively, please refer to Figure 2 In the case of using concrete building modules, the column assembly 140 may also have an embedded component 145, such as a steel bar, which is connected to the column connecting plate 144 and is located inside the column 141. For example, the column connecting plate 144 and the embedded component 145 are first installed, and then the connected column connecting plate 144 and the embedded component 145 are placed in a mold. Concrete is poured into the mold cavity, and the mold is removed after molding to obtain the column 141 connected with the column connecting plate 144 and the embedded component 145.

[0106] See also Figures 1 to 4 The first connecting member 131 has a first mounting hole 131a connected to the outside, and the first contact surface is located on the inner wall of the first mounting hole 131a. The second connecting member 132 extends to the inside of the first connecting member 131 via the first mounting hole 131a. The second connecting member 132 includes a side plate 136, which is arranged along the first horizontal direction D1 and has a second contact surface 132a. Further, the first mounting holes 131a are arranged in pairs, and adjacent first mounting holes 131a are spaced along the second horizontal direction D2. Correspondingly, the side plates 136 are arranged in pairs, and adjacent side plates 136 are spaced along the second horizontal direction D2 and are suitable for the first mounting holes 131a. Figure 4 In the embodiment, the second connecting member 132 further includes an end plate 137, and the end plate 137 is connected to the side plate 136 adjacent to each other along the second horizontal direction D2. Preferably, the side plate 136 and the end plate 137 are integrally formed, or in other words, the second connecting member 132 is an integral structure.

[0107] The end plate 137 has a first fixing hole 132b that penetrates the end plate 137 along the first horizontal direction D1. The first connecting member 131 also has a second fixing hole 131b that communicates with the outside. Along the first horizontal direction D1, the second fixing hole 131b corresponds to the first fixing hole 132b. Figure 4 In the embodiment, the second fixing hole 131b is located between the adjacent first mounting holes 131a along the second horizontal direction D2.

[0108] After the connection assembly 130 is connected to the upper module 110 and the lower module 120, the positions of the first connection member 131 and the second connection member 132 can also be locked. Therefore, the connection assembly 130 also includes a first fastener 135, the first fastener 135 is arranged along the first horizontal direction D1, and the second fixing hole 131b is suitable for the first fastener 135. The first fastener 135 passes through the first fixing hole 132b and is connected to the second fixing hole 131b. For example, the first fastener 135 is configured as a bolt, and the second fixing hole 131b has an internal thread suitable for the bolt. Alternatively, the connection assembly 130 also includes a second fastener suitable for the first fastener 135. The second fastener is located inside the first connection member 131 and corresponds to the position of the second fixing hole 131b along the first horizontal direction D1, and the first fastener 135 passes through the first fixing hole 132b and the second fixing hole 131b and is connected to the second fastener. For example, the first fastener 135 is configured as a bolt, the first fixing hole 132b and the second fixing hole 131b are configured as common through holes, and the second fastener is configured as a nut suitable for the bolt. In order to facilitate the assembly of the first fastener 135, Figure 4 In the embodiment, the first fixing hole 132b is configured as an elongated strip and extends along the vertical direction DH.

[0109] See also Figure 5 In order to prevent the first connecting member 131 from sliding into the interior of the column 141 through the second connecting port 141b, the interior of the column 141 also has a limiting member 146. It can be understood that the limiting member 146 is used to limit the position of the first connecting member 131 relative to the column 141 along the vertical direction DH.

[0110] Please continue reading Figures 1 to 5In order to ensure that the elevation of the modular building 100 meets the requirements after the upper module 110 and the lower module 120 are installed in the modular building 100, appropriate leveling operations should be performed during the assembly process. Therefore, the connection assembly 130 also includes a leveling member 133, such as a leveling gasket. The leveling member 133 has a first positioning hole 133a that penetrates itself along the vertical direction DH and is suitable for the first connection member 131. The leveling member 133 is sleeved on the outer periphery of the first connection member 131, and the leveling member 133 is clamped between the upper module 110 and the lower module 120. Preferably, along the second horizontal direction D2, the column assemblies 140 are arranged in pairs and abut against each other; correspondingly, along the second horizontal direction D2, the first connection members 131 are arranged in pairs and spaced from each other. In order to establish the connection of the column assemblies 140 arranged in pairs along the second horizontal direction D2, the connection assembly 130 also includes a horizontal connection plate 134. The horizontal connecting plate 134 has a second positioning hole 134a suitable for the first connecting member 131, and the second positioning hole 134a penetrates the horizontal connecting plate 134 along the vertical direction DH. The horizontal connecting plate 134 is sleeved to the outer periphery of the first connecting member 131 adjacent to each other along the second horizontal direction D2. Figure 1 and Figure 3 , along the vertical direction DH, the first mounting holes 131a of a single first connecting member 131 are arranged in pairs, and adjacent first mounting holes 131a are spaced apart along the vertical direction DH. It should be noted that, since the first contact surface is located on the inner wall of the first mounting hole 131a, in order to optimize the force of the connecting assembly 130 in the vertical direction DH, the adjacent first contact surfaces along the vertical direction DH are symmetrically arranged relative to the middle of the first connecting member 131.

[0111] In addition, one of the upper module 110 and the lower module 120 may be configured as a base plate 150, and the other may include a column assembly 140. Figure 6 A modular building 200 is shown, where the upper module 110 includes a column assembly 140, and the lower module 120 is configured as a base plate 150. In an embodiment not shown, the upper module 110 can be configured as a base plate 150, and the lower module 120 includes a column assembly. For example, the connection assembly 130 (or the first connection member 131) is connected to the base plate 150 by welding. Figure 7 A modular building 300 is shown, compared to Figure 6 The modular building 200 shown is different in that two column assemblies are stacked on top of the base plate 150 along the vertical direction DH.

[0114] The leveling member 133 is sleeved onto the outer circumference of the first connecting member 131 .

[0115] The upper module 110 is connected to the first connection member 131 so that the leveling member 133 is sandwiched between the upper module 110 and the lower module 120 .

[0116] The second connecting member 132 is passed through the second connecting port 141 b so that the second connecting member 132 is connected to the first connecting member 131 .

[0117] When the upper module 110 includes column assemblies 140 arranged in pairs along the second horizontal direction D2, the lower module 120 is first placed on the placement surface, and the first connecting members 131 are connected to the lower module, and adjacent first connecting members 131 are spaced apart along the second horizontal direction D2.

[0118] The horizontal connecting plate 134 is sleeved onto the outer periphery of the first connecting member 131 adjacent to each other along the second horizontal direction D2.

[0119] The leveling member 133 is sleeved on the outer periphery of the first connecting member 131. It should be noted that when adjusting the elevation, due to the size difference of the column assembly 140, the thickness of the leveling member 133 may be different.

[0120] The upper module 110 is connected to the first connection member 131 so that the leveling member 133 is sandwiched between the upper module 110 and the lower module 120 .

[0121] The second connecting member 132 is passed through the second connecting port 141 b so that the second connecting member 132 is connected to the first connecting member 131 .
