Both ends of the first upper bottom side beam 141 in the length direction of the first modular building unit 100 may be connected with the two first corner posts 111, respectively. The first upper bottom side beam 141 may be connected to the first corner post 111 by welding.

Preferably, opposite end surfaces of the first upper bottom side beam 141 in the length direction of the first modular building unit 100 may be connected with surfaces of the two first corner posts 111 opposite to each other, respectively. In this way, the first upper bottom side beam 141 may be disposed between the two first corner posts 111 along the length of the first modular building unit 100. Opposite ends of each first upper bottom-side beam 141 are connected to two first corner columns 111, so that the connection strength between the first upper bottom-side beam 141 and the first corner columns 111 is ensured, and the stress of the first upper bottom-side beam 141 can be transmitted to the first corner columns 111, so that the first corner columns 111 can disperse the pressure borne by the first upper bottom-side beam 141.

The first upper chassis structure 140 may include at least one first upper bottom cross member 142, and both sides of the first upper bottom cross member 142 in the width direction of the first modular building unit 100 may be connected with two first upper bottom side members 141, respectively.

Opposite sides of each first upper bottom beam 142 are connected to two first upper bottom beams 141.

A plurality of first upper bottom cross members 142 may be spaced apart along the length of the first modular building unit 100. Thus, a plurality of first upper bottom side beams 142 may be provided between the two first upper bottom side beams 141, each first upper bottom side beam 142 being connected to the first upper bottom side beam 141 along opposite sides of the first modular building unit 100. Thus, the structural strength of the first upper bottom side beam 141 is improved, the stress is uniformly dispersed, and the first upper bottom side beam 141 is prevented from being broken.

The first upper floor 143 is laid above the first upper bottom cross member 142 for supporting electronic equipment such as a cabinet, an air conditioner, and the like. The first upper floor 143 may be made of a steel floor. Of course, the first upper floor 143 may be made of calcium sulfate floor, which can play a role in fire prevention and static electricity prevention, thereby improving safety.

Preferably, both sides of the first upper floor 143 in the width direction of the first modular building unit 100 are connected with two first upper bottom side beams 141, respectively. The first upper floor 143 may be connected to both the first upper bottom side rail 141 and the first upper bottom cross rail 142 by welding, but of course, the first upper floor 143 may also be connected to both the first upper bottom side rail 141 and the first upper bottom cross rail 142 by bolts. The lower surfaces of both sides of the first upper floor 143 in the width direction of the first modular building unit 100 may be connected with the upper surface of the first upper bottom side beam 141. In this way, the first upper floor 143 may be constructed as a one-piece floor in the width direction of the first modular building unit 100, reducing the number of floors. The lower surface of the middle portion of the first upper floor 143 may be connected with the upper surface of the first upper floor cross member 142.

In order to avoid leakage of electronic equipment such as a cabinet, as shown in fig. 2, a first floor paste 144 may be laid on the first upper floor 143, and the first floor paste 144 may be laid on an upper surface of the first upper floor 143. First ground is glued 144 and can be glued for static ground, can set up electronic equipment such as data center rack air conditioner on the static ground is glued to avoid the electricity conduction of rack to go up chassis structure, improved the security.

Returning now to fig. 1, the first upper chassis structure 140 and the first lower chassis structure 120 may have a distance of 300mm to 1100mm in the height direction of the first modular building unit 100, thereby leaving enough space for installing pipes or equipment. The first upper chassis structure 140 and the first lower chassis structure 120 may be hollow between them to act as a cavity cold sink. Cool air may enter the space between the first upper chassis structure 140 and the first lower chassis structure 120. Preferably, the first upper floor 143 may be provided with a vent hole through which cool air may enter above the first upper chassis structure 140 for cooling down electronic equipment such as the cabinet.

A specific structure of the first lower chassis structure 120 will be described below.

The first lower chassis structure 120 may include a first lower bottom side member 121 and a first lower bottom cross member 122, a length direction of the first lower bottom side member 121 may be parallel to a length direction of the first modular building unit 100, and a length direction of the first lower bottom cross member 122 may be parallel to a width direction of the first modular building unit 100. The first lower bottom side beam 121 and the first lower bottom cross beam 122 are disposed perpendicular to each other.

The first lower bottom side beam 121 is located below the first upper bottom side beam 141 in the height direction of the first modular building unit 100. Preferably, a connection structure may be provided at a side of a lower portion of the first corner post 111, the connection structure may be provided between the first lower bottom side beam 121 and the first corner post 111, and the connection structure may be used to connect with a lock. The dimension of the first lower bottom side sill 121 in the length direction of the first modular building unit 100 may be smaller than the dimension of the first upper bottom side sill 141, and the dimension of the first lower bottom side sill 121 in the width direction of the first modular building unit 100 may be larger than the dimension of the first upper bottom side sill 141, thereby improving the structural strength of the first lower bottom side sill 121.

The first lower chassis structure 120 may include two first lower bottom side members 121, and the two first lower bottom side members 121 may be oppositely disposed in the width direction of the first modular building unit 100. Both ends of the first lower bottom side beam 121 in the length direction of the first modular building unit 100 may be connected to lower portions of the two first corner posts 111, respectively. The first lower bottom side member 121 may be connected to the first corner post 111 by welding.

Preferably, opposite end surfaces of the first lower bottom side member 121 in the length direction of the first modular building unit 100 may be connected with surfaces of the two first corner posts 111 opposite to each other, respectively. In this way, the first lower bottom side member 121 may be disposed between the two first corner posts 111 in the length direction of the first modular building unit 100. Opposite ends of each of the first lower bottom side members 121 are connected to the two first corner posts 111, so that the connection strength of the first lower bottom side member 121 and the first corner posts 111 is ensured, and the stress of the first upper bottom side member 141 can be transmitted to the first lower bottom side member 121 via the first corner posts 111, thereby enabling the first lower bottom side member 121 to disperse the pressure borne by the first upper bottom side member 141.

Further, the dimension of the first upper chassis structure 140 in the width direction of the first modular building unit 100 is smaller than the dimension of the first lower chassis structure 120. Specifically, the distance between the two outer surfaces of the first upper bottom side members 141 facing in opposite directions in the width direction of the first modular building unit is smaller than the distance between the two outer surfaces of the first lower bottom side members 121 facing in opposite directions. The outer surface of the first upper bottom side beam 141 refers to a surface of the first upper bottom side beam 141 facing the exterior of the first modular building unit. The outer surface of the first lower bottom side member 121 refers to a surface of the first lower bottom side member 121 that faces the outside of the first modular building unit. Thereby, a sufficient installation space can be left.

Of course, the dimension of the first upper chassis structure 140 in the width direction of the first modular building unit 100 may also be equal to the dimension of the first lower chassis structure 120. The distance between the two outer surfaces of the first upper bottom side members 141 facing in opposite directions in the width direction of the first modular building unit is equal to the distance between the two outer surfaces of the first lower bottom side members 121 facing in opposite directions. Therefore, the installation precision is reduced, and the installation difficulty is reduced.

The first lower chassis structure 120 may include at least one first lower bottom cross member 122, and both sides of the first lower bottom cross member 122 in the width direction of the first modular building unit 100 may be connected with two first lower bottom side members 121, respectively. The first lower cross member 122 may be connected to the first lower side member 121 by welding. Preferably, opposite side surfaces of the first lower bottom cross member 122 in the width direction of the first modular building unit 100 may be connected with surfaces of the two first lower bottom side members 121 opposite to each other, respectively. In this way, the first lower bottom cross member 122 may be disposed between the two first lower bottom side members 121 in the width direction of the first modular building unit 100. Opposite sides of each first lower bottom beam 122 are connected to two first lower bottom beams 121.

A plurality of first lower bottom cross members 122 may be spaced apart along the length of the first modular building unit 100. Thus, a plurality of first lower bottom side beams 122 are arranged between the two first lower bottom side beams 121, each first lower bottom side beam 122 being connected to the first lower bottom side beam 121 along opposite sides of the first modular building unit 100. Thus, the structural strength of the first lower sill 121 is improved, the stress is uniformly dispersed, and the first lower sill 121 is prevented from being broken. The first modular building unit 100 may further comprise a conduit having electrical wires disposed therein, which may be electrically connected to the electronics located above. The piping may be laid on the first lower bottom beams 122 or between adjacent first lower bottom beams 122 for ease of management.

The first lower chassis structure 120 may further include a first lower floor 123, the first lower floor 123 being laid over the first lower bottom side rail 121 and the first lower bottom cross rail 122. The first lower floor 123 may be made of a steel floor. Preferably, both sides of the first lower floor 123 in the width direction of the first modular building unit 100 are connected with the two first lower bottom side beams 121, respectively. The lower surfaces of both sides of the first lower floor 123 in the width direction of the first modular building unit 100 may be connected with the upper surface of the first lower bottom side beam 121. In this way, the first lower floor 123 may be constructed as a one-piece floor in the width direction of the first modular building unit 100, reducing the number of floors.

The lower surface of the middle portion of the first lower floor 123 may be connected with the upper surface of the first lower floor cross member 122. The first lower floor 123 may be connected to the first lower bottom side rail 121 and the first lower bottom cross rail 122 by welding. The first lower floor 123 may be provided with pipes, devices, wire racks, grounding devices, etc. The sides of the first lower floor 123 may be provided with a skirt to avoid exposure of the underlying piping to the outside of the first modular building unit 100. The skirt may be integrally formed with the first lower floor 123, thereby facilitating assembly.

Further, the first lower chassis structure 120 further includes a first bottom plate 124, and the first bottom plate 124 is disposed below the first lower bottom cross member 122. Both sides of the first floor panel 124 in the width direction of the first modular building unit 100 are connected to surfaces of the two first lower bottom side beams 121 facing each other, respectively. The first floor plate 124 may be connected with a surface of the first lower bottom side beam 121 located at an inner side of the modular building unit. Thus, the pipes are prevented from being exposed from below the first lower chassis structure 120, the flatness of the bottom of the first modular building unit 100 is ensured, and the external structure is prevented from damaging the structure and equipment inside the first modular building unit 100.

Fig. 3 and 4 show a block diagram of a modular building unit according to a second preferred embodiment of the invention. The first modular building unit 100 further comprises a first truss structure 150, the first truss structure 150 being disposed at a side of the first modular building unit 100 between the first upper chassis structure 140 and the first lower chassis structure 120 to improve the structural strength of the first modular building unit 100.

Specifically, the first truss structure 150 may be disposed between the first lower bottom side member 121 and the first upper bottom side member 141. The first truss structure 150 may include a first truss web 151, with the bottom of the first truss web 151 connected to the first lower bottom side beam 121 and the top of the first truss web 151 connected to the first upper bottom side beam 141.

The upper surface of the first truss web 151 may be connected to the lower surface of the first upper bottom side beam 141, and preferably, the first truss web 151 may be connected to the first upper bottom side beam 141 by welding. The lower surface of the first truss web 151 may be connected to the upper surface of the first lower bottom side beam 121. Preferably, the first truss web 151 may be connected to the first lower bottom side beam 121 by welding. The first truss web members 151 may support the first upper bottom side beam 141 to improve the structural strength of the first upper bottom side beam 141, and the compressive force to which the first upper bottom side beam 141 is subjected may be transmitted to the first lower bottom side beam 121 via the first truss web members 151, thereby preventing the first upper bottom side beam 141 from being broken.

The first truss web members 151 may be obliquely disposed between the first lower bottom side beam 121 and the first upper bottom side beam 141, and the adjacent first truss web members 151, the first lower bottom side beam 121, and the first upper bottom side beam 141 may collectively form a triangular structure, thereby further improving structural strength such that the first truss web members 151 can stably support the first upper bottom side beam 141.

The first modular building unit further comprises a first top side beam, a first top cross beam and a first top plate, and two ends of the first top side beam in the length direction of the first modular building unit are connected with the tops of the two first corner columns respectively. The two sides of the first top cross beam in the width direction of the first modular building unit are connected with the two first top side beams respectively. The first top plate is laid above the first top side beam. Therefore, the electronic equipment is arranged in the first modular building unit, and the first top side beam, the first top cross beam and the first top plate which are positioned above can uniformly disperse the pulling force from the lower part, so that the deformation of the first upper chassis structure positioned below is avoided.

The invention also provides a modular building comprising the modular building unit.

Further, the first upper bottom side beam 141 of the first modular building unit 100 is also provided with a first connection hole (not shown). The first connection hole may be provided on a side surface of the first upper bottom side member 141 facing the outside of the first modular building unit 100. As shown in fig. 1 and 2, the first upper chassis structure 140 further includes a first connector 161 and a first supporter 162, and the first supporter 162 is connected to the first connection hole through the first connector 161. The first connector 161 may be configured as a bolt. The first connection hole may be configured as a long hole, such as a kidney-shaped hole. The first connector 161 may be movable in a height direction of the modular building unit with respect to the first connection hole, thereby adjusting the position of the first supporter 162.

Specifically, the first support 162 may include a first connection section 163 and a first support section 164, the first connection section 163 being connected with the first support section 164.

Thereby reducing the gap between the first modular building unit 100 and the second modular building unit 200. The connection floor 270 may be made of calcium sulfate floor, which can play a role in fire prevention and static electricity prevention, thereby improving safety.

To ensure flatness, the first connector 161 may be movable in the height direction of the first modular building unit 100 with respect to the first connection hole, and the second connector 261 may be movable in the height direction of the second modular building unit 200 with respect to the second connection hole to adjust the positions of the first and

second supports

162 and 264 in the height direction of the modular building units, thereby adjusting the positions of the first and

second support sections

164 and 264 in the height direction of the modular building units, so as to ensure that the upper surface of the connection floor 270 is flush with the upper surface of the first upper floor 143 of the first building unit and the upper surface of the connection floor 270 is flush with the upper surface of the second upper floor 243 of the second building unit.

Of course, the first floor board 143 may be provided with the first floor paste 144, the second floor board 243 may be provided with the second floor paste 244, and the upper surface of the connecting floor board 270 may be flush with the upper surfaces of the first floor paste 144 and the second floor paste 244, so as to ensure flatness.

Of course, the modular building may comprise a larger number of modular building units, such as three, four or five, and a person skilled in the art may arrange a plurality of modular building units side by side in the width direction of the modular building units, depending on the actual situation.

Figures 6 and 7 show a modular building unit according to a third preferred embodiment of the present invention.

To facilitate installation of the connection floor, the present invention also provides a third modular building unit 300, the structure of the third modular building unit 300 being similar to that of the second modular building unit 200 except that the third upper floor 343 is not connected to the third upper bottom side member 341 and the third connecting member 361 and the third supporting member 362 are not provided on the third upper bottom side member 341. The upper surface of the third upper floor beam 342 of the third upper chassis structure 340 of the third modular building unit 300 projects above the upper surface of the third upper floor beam 341.

In particular, the modular building comprises two third modular building units 300, the two third modular building units 300 being arranged side by side in the width direction of the third modular building units 300. In order to secure the connection strength between the modular building units and prevent shaking between the third modular building units 300, the smaller the distance between the two third modular building units 300, the better.

In order to prevent inconvenience in installation of the connection floor due to an excessively small gap, the connection floor is not provided on the third upper floor beam 341 but on the outer surface of the third upper floor beam 342. The upper surface of the third upper floor beam 342 of the third upper chassis structure 340 of the third modular building unit 300 projects above the upper surface of the third upper floor beam 341. An outer surface of a portion of the third upper floor crossmember 342 protrudes from an upper surface of the third upper floor crossmember 341 in the height direction of the third modular building unit 300. I.e., the outer surface of a portion of the third upper floor beam 342 is exposed. The outer surface of third upper bottom cross member 342 refers to the surface of third upper bottom cross member 342 facing the exterior of third modular building unit 300 in the width direction of third modular building unit 300.

A third connecting member 361 and a third supporting member 362 are provided on the outer surface of part of the third upper floor beam 342 described above. The third connecting section 363 is connected to the outer surface of the portion of the third upper floor crossmember 342 described above by a third connecting member 361. In this way, the installation space between the two third connection sections 363, that is, the installation space for installing the connection floor is widened. Thus, the size of the connection floor in the width direction of the third modular building unit 300 can be widened without producing a connection floor of a smaller size, reducing the difficulty of processing and installation.

Meanwhile, the dimension of the third upper bottom side member 341 in the width direction of the third modular building unit 300 is prevented from being excessively small, the dimension of the third upper bottom side member 341 in the width direction of the third modular building unit 300 is ensured, the truss structure can be ensured to be mounted to the third upper bottom side member 341 and the third lower bottom side member 321, and the structural strength is ensured.
