It should be understood that fig. 4 is only a schematic diagram illustrating that a plurality of prefabricated module units 100 may be assembled to form a data center 200 with a multi-layer architecture, and the specific number of layers of the data center 200 is not limited to the three-layer architecture shown in fig. 4, and may also be configured as a two-layer architecture, a four-layer architecture, a five-layer architecture, or an architecture with more than five layers, and the specific number of layers of the data center 200 may be selected according to various factors such as actual assembly requirements, and the size of a space of a scene, and is not limited thereto.

It should be noted that, the data center 200 is usually laid out in an outdoor scene, but the layout of the data center 200 is not limited to the outdoor scene, and all the scene applications that can meet the requirements of the construction of the data center 200 and the layout conditions for laying out the data center 200 belong to the scope protected by the embodiments of the present application, and are not strictly limited thereto.

The structure of the prefabricated modular unit 100 will be described below by taking one of the prefabricated modular units 100 as an example, and in the following description, the structural improvement of the prefabricated modular unit 100 in the embodiment of the present application can be applied to other prefabricated modular units 100 of the data center 200 without conflict, and the present application is not limited thereto. And fig. 5-17 described below, it is possible to retain only the frames 10 of the prefabricated module units 100 and remove the internal functional modules 210 and/or wall boards, so as to enable a plurality of frames 10 to be spliced into the basic architecture of the integrated data center 200, wherein the dotted lines in fig. 5 and 6 may represent the boundary lines dividing the accommodating space 14, and the dotted lines are taken as the boundary lines, and the part on one side of the dotted lines belongs to the first subspace 141, and the part on the other side of the dotted lines belongs to the second subspace 142.

Referring to fig. 5, 6 and 7 in combination, the prefabricated modular unit 100 includes a frame 10, a top plate 30 and a bottom plate 40, the top plate 30 being connected to the top of the frame 10, and the bottom plate 40 being connected to the bottom of the frame 10. Wherein the top panel 30 and the bottom panel 40 are both wall panel structures of the prefabricated modular unit 100.

Specifically, the frame 10 includes a top frame body 11 and a bottom frame body 12, and a pillar 13 connected between the top frame body 11 and the bottom frame body 12. The top shelf 11 may be understood as a shelf on the side away from the ground when the prefabricated modular unit 100 is placed on the ground, and the bottom shelf 12 may be understood as a side shelf close to the ground when the prefabricated modular unit 100 is placed on the bottom.

The top deck frame 11 includes two first longitudinal beams 113 and two first cross beams 114, the two first longitudinal beams 113 are disposed oppositely, the two first cross beams 114 are disposed oppositely and connected between the two first longitudinal beams 113, and the two first longitudinal beams 113 and the two first cross beams 114 are connected end to end according to the connection relationship of "first longitudinal beam 113-first cross beam 114-first longitudinal beam 113-first cross beam 114" to form the top deck frame 11 of the prefabricated module unit 100. In other words, the top shelf 11 is the top beam structure of the prefabricated modular unit 100.

And the dimension of each of the two first longitudinal beams 113 in the extending direction thereof is larger than the dimension of each of the two first cross beams 114 in the extending direction thereof 114. The extending direction of the first longitudinal beam 113 is perpendicular to the extending direction of the first cross beam 114, the dimension of the first longitudinal beam 113 along the extending manner thereof can be understood as the length of the first longitudinal beam 113, and the dimension of the first cross beam 114 along the extending direction thereof can be understood as the length of the first cross beam 114.

In other words, comparing the lengths of both the first longitudinal beam 113 and the first cross beam 114, the first longitudinal beam 113 is a beam structure having a longer length than the first cross beam 114. It should be noted that the dimension of each first longitudinal beam 113 along the extending direction thereof may also be the same as the dimension of each first transverse beam 114 along the extending direction thereof, and may be selected according to actual situations, and is not strictly set.

The bottom shelf body 12 comprises two second longitudinal beams 121 and two second cross beams 122, the two second longitudinal beams 121 are oppositely arranged, the two second cross beams 122 are oppositely arranged and connected between the two second longitudinal beams 121, and the two second longitudinal beams 121 and the two second cross beams 122 are connected end to end according to the connection relationship of the second longitudinal beams 121-the second cross beams 122-the second longitudinal beams 121-the second cross beams 122 "to form the bottom shelf body 12 of the prefabricated module unit 100. In other words, the sub-frame 12 is the bottom beam structure of the prefabricated modular unit 100.

And each of the two second longitudinal beams 121 has a dimension in the extending direction thereof that is greater than a dimension in the extending direction of each of the two second cross beams 122. The extending direction of the second longitudinal beam 121 is perpendicular to the extending direction of the second transverse beam 122, the dimension of the second longitudinal beam 121 along the extending manner thereof can be understood as the length of the second longitudinal beam 121, and the dimension of the second transverse beam 122 along the extending direction thereof can be understood as the length of the second transverse beam 122.

In other words, comparing the lengths of both the second longitudinal beam 121 and the second cross beam 122, the second longitudinal beam 121 is a beam structure having a longer length than the second cross beam 122. That is, the second longitudinal beams 121 are long-side beam structures in the prefabricated module unit 100, and the second transverse beams 122 are short-side beam structures in the prefabricated module unit 100. It should be noted that the dimension of each second longitudinal beam 121 along the extending direction thereof may also be the same as the dimension of each second cross beam 122 along the extending direction thereof, and may be selected according to actual situations, and is not strictly set.

It should be understood that the first longitudinal beam 113 of the top shelf body 11 is disposed to correspond to the second longitudinal beam 121 of the bottom shelf body 12, and the first lateral beam 114 of the top shelf body 11 is disposed to correspond to the second lateral beam 122 of the bottom shelf body 12. That is, the first longitudinal beam 113 of the top stage frame body 11 extends in the same direction and length as the second longitudinal beam 121 of the bottom stage frame body 12, and the first lateral beam 114 of the top stage frame body 11 extends in the same direction and length as the second lateral beam 122 of the bottom stage frame body 12.

The quantity of stand 13 is four, and four stands 13 are connected respectively in four corners departments of top layer support body 11 and bottom support body 12, can make and form actual joint relation between top layer support body 11 and the bottom support body 12. Therefore, the upright column 13, the top shelf 11 and the bottom shelf 12 can cooperate to form a frame structure of the prefabricated module unit 100, and the functional module 210 is disposed in the accommodating space 14 defined by the top shelf 11, the bottom shelf 12 and the upright column 13.

It can be understood that the top plate 30 can be connected to the top 111 of the top shelf 11, and the bottom plate 40 can be connected to the bottom shelf 12, so that when a plurality of prefabricated modular units 100 are vertically stacked, the internal structures of two vertically adjacent prefabricated modular units 100 can be protected by the bottom plate 40 of the upper prefabricated modular unit 100 and the top plate 30 of the lower prefabricated modular unit 100, and the adjacent prefabricated modular units 100 cannot interfere with each other due to the non-shielding structure, thereby having good protection effect.

It should be noted that, depending on the actual application scenario of the prefabricated modular unit 100, the prefabricated modular unit 100 may also have wall panels disposed on the peripheral sides of the prefabricated modular unit 100. That is, according to the actual application scenario of the prefabricated modular unit 100, the number, installation position, and shape structure of the wall panels of the prefabricated modular unit 100 can be flexibly adjusted, so that the prefabricated modular unit 100 is configured as a closed box structure or a semi-closed box structure, which is not strictly limited.

In the embodiment of this application, top layer support body 11, bottom support body 12 and stand 13 connect the box simple structure who forms and intensity accord with prefabricated modular unit 100's intensity demand, can support with a plurality of prefabricated modular unit 100 levels and case connection or perpendicular multilayer pile up to can realize the nimble dilatation in data center 200's space, be favorable to the application demand under the multi-scene. By improving the structure of the top rack 11, the space utilization rate inside the data center 200 can be improved on the basis of ensuring that the data center 200 has good working performance, which will be described in detail below.

Referring to fig. 5, 6 and 7, the top shelf 11 includes a top portion 111 and a bottom portion 112 parallel to the vertical columns 13, the top portion 111 is used for connecting two adjacent prefabricated modular units 100, and the bottom portion 112 is disposed between the top portion 111 and the bottom shelf 12, i.e., the vertical distance between the bottom portion 112 and the bottom shelf 12 is smaller than that between the top portion 111 and the bottom shelf 12. The bottom 112 is used as a boundary for dividing the inner space of the accommodating space 14, a first sub-space 141 is formed between the bottom 112 and the top 111, and a second sub-space 142 is formed between the bottom 112 and the bottom shelf 12.

Since the top 111 of the top shelf 11 can be connected to two adjacent prefabricated modular units 100, the top 111 of the top shelf 11 is connected to the adjacent prefabricated modular units 100 in the prefabricated modular units 100 with respect to the bottom 112 of the top shelf 11, and defines the boundary of the peripheral dimension of the prefabricated modular units 100. That is, the top 111 of the top frame 11, the bottom frame 12 and the vertical column 13 can collectively define the receiving space 14.

And the top 111 of the top shelf 11 and the bottom 112 of the top shelf 11 are two ends of the top shelf 11 in a direction parallel to the vertical column 13, and the bottom 112 of the top shelf 11 is disposed between the top 111 of the top shelf 11 and the bottom shelf 12. That is, the vertical distance between the top 111 of the top shelf 11 and the bottom shelf 12 is not the same as the vertical distance between the bottom 112 of the top shelf 11 and the bottom shelf 12, so that there is a difference in vertical distance between the top 111 of the top shelf 11 and the bottom 112 of the top shelf 11. Based on this, the top shelf 11 can be stretched out a certain vertical space by the difference of the vertical distance between the top 111 and the bottom 112 in the direction parallel to the vertical columns 13.

And the accommodating space 14 can be divided into two parts by arranging the top 111 and the bottom 112 of the top shelf 11 with height difference, wherein the first sub-space 141 can be enclosed by the top 111 of the top shelf 11, the upright column 13 and the bottom 112 of the top shelf 11, and the second sub-space 142 can be enclosed by the bottom 112 of the top shelf 11, the upright column 13 and the bottom shelf 12.

When the space dimensions of the two spaces are considered according to the height of the human body of the worker, the first subspace 141 surrounded by the bottom 112 of the top layer frame body 11, the upright post 13 and the bottom layer frame body 12 is a space which is less involved by the worker in the accommodating space 14, the space can be utilized by utilizing the height difference between the top part 111 and the bottom part 112 in the space, and one or more devices of ventilating ducts, wire racks, cables, buses, exhaust systems, cables and the like are arranged in the space. And the second subspace 142 surrounded by the top 111 of the top layer frame body 11, the upright column 13 and the bottom 112 of the top layer frame body 11 is a moving space which is more suitable for the movement of the working personnel in the accommodating space 14, in the part of space, the working personnel can conveniently move, carry, maintain and the like, and the suitable space can provide good stability and reliability for the movement of the working personnel.

By dividing the accommodating space 14 into two different functional areas, the layout space of the functional modules 210 and the activity space of the staff can be standardized at the bottom of the prefabricated modular unit 100, and the available space of the wiring or power, exhaust and other systems can be distributed at the top of the prefabricated modular unit 100. On one hand, the method can be distinguished from the prior art that the wiring space is arranged at the bottom, so that an overhead board for providing the moving stability of workers needs to be additionally arranged, the height of the bottom layer frame body 12 can be matched with the height of the bottom plate 40 arranged on the bottom layer frame body, so that the bottom plate 40 arranged on the bottom layer frame body 12 can provide good flatness on the basis of not occupying extra space, the space layout in the accommodating space 14 is not influenced by the obvious upright post 13 structure in the accommodating space 14 caused by the fact that the bottom beam protrudes out of the bottom plate 40, the space size and the cost occupied by additionally arranging an elevating plate can be effectively reduced, therefore, a larger activity space and a more compact functional module 210 can be provided for workers in a limited space, the space utilization rate in the prefabricated module unit 100 is effectively improved, and the overall power density of the data center 200 is favorably improved. On the other hand, the routing space is arranged at the top of the prefabricated modular unit 100, so that the layout space of the functional module 210 at the bottom of the prefabricated modular unit 100 and the activity space of workers can be avoided, the idle space at the top of the prefabricated modular unit 100 can be effectively utilized, and routing or power, exhaust and other systems are correspondingly arranged, so that the available space inside the prefabricated modular unit 100 is enlarged, and the working reliability is good.

Illustratively, the height of the first sub-space 141 defined by the bottom 112 of the top shelf 11, the pillar 13 and the bottom shelf 12 is smaller than the height of the second sub-space 142 defined by the top 111 of the top shelf 11, the pillar 13 and the bottom 112 of the top shelf 11, wherein the height is a dimension parallel to the pillar 13, that is, a dimension in the vertical direction. In other words, the size of the space defined by the bottom 112 of the top shelf 11, the pillar 13 and the bottom shelf 12 is smaller than the size of the space defined by the top 111 of the top shelf 11, the pillar 13 and the bottom 112 of the top shelf 11.

Therefore, the second subspace 142, which is defined by the top 111 of the top frame 11, the upright post 13 and the bottom 112 of the top frame 11 together, can be used as a main space to accommodate the functional module 210 and provide an activity space for workers, and the first subspace 141, which is defined by the bottom 112 of the top frame 11, the upright post 13 and the bottom frame 12 together, can be used as an auxiliary space to accommodate one or more combinations of a ventilation pipeline, a wire frame, a cable, a bus, an exhaust system, a refrigeration system and an electric power system. With the arrangement, the equipment can be reasonably arranged, and the waste of the space inside the prefabricated modular unit 100 is effectively avoided, so that the available space inside the prefabricated modular unit 100 is utilized to the maximum extent, and the space utilization rate is high.

In one possible embodiment, the first sub-space 141 is a hanging space, and each device disposed in the first sub-space 141 can be hung inside the first sub-space 141 by being hung on the top plate 30. The second subspace 142 is a bearing space, and each device disposed in the second subspace 142 may be fixedly disposed inside the second subspace 142 by being carried by the bottom plate 40.

The possibility of the bottom 112 of the top shelf 11, the upright 13 and the bottom shelf 12 together enclosing the first subspace 141 will be described below by three possible embodiments.

In one possible embodiment, as shown in fig. 7, in the top shelf 11, the height of each first longitudinal beam 113 of the two first longitudinal beams 113 is greater than the height of each first transverse beam 114 of the two first transverse beams 114, and the height of each first longitudinal beam 113 of the top shelf 11 is greater than the height of the corresponding second longitudinal beam 121 of the bottom shelf 12, wherein the height is a dimension parallel to the direction of the vertical column 13. That is, in the top shelf 11, two first cross members 114 and two first longitudinal members 113 cooperate to constitute the top portion 111 of the top shelf 11, and two first longitudinal members 113 cooperate to constitute the bottom portion 112 of the top shelf 11.

Therefore, by changing the height of the first longitudinal beam 113, a height difference can be formed between the first longitudinal beam 113 and the first cross beam 114, so that the top frame 11 can be stretched out to a certain vertical space, which is beneficial to enclosing a part of space by the bottom 112 of the top frame 11, the upright column 13 and the bottom frame 12. With this arrangement, the top frame 11 can have a structural condition for dividing the inner space of the prefabricated module unit 100 by making the beam structures constituting the top frame 11 have a height difference, and the structure is simple and reliable.

In addition, the height of the first cross beam 114 is not changed, so that the first cross beam 114, the upright column 13 and the first longitudinal beam 113 jointly form an opening entering the first subspace 141, a certain moving space can be provided for arrangement of various routing lines in a ventilation pipeline, a line frame, a cable, a bus, an exhaust system, a refrigeration system and an electric power system, and a guiding effect is provided, so that various devices can smoothly enter the bottom 112 of the top layer frame body 11 from the end face of the prefabricated module unit 100, and the upright column 13 and the first subspace 141 enclosed by the bottom layer frame body 12 jointly are favorable for reasonably utilizing the space arrangement inside the prefabricated module unit 100.

In another possible embodiment, in the top shelf 11, the height of each first longitudinal beam 113 of the two first longitudinal beams 113 is the same as the height of each first transverse beam 114 of the two first transverse beams 114, the height of each first longitudinal beam 113 of the top shelf 11 is greater than the height of the corresponding second longitudinal beam 121 of the bottom shelf 12, and the height of each first transverse beam 114 of the top shelf 11 is greater than the height of the corresponding second transverse beam 122 of the bottom shelf 12, wherein the height is a dimension parallel to the direction of the vertical column 13. That is, in the top shelf 11, two first cross members 114 and two first longitudinal members 113 cooperate to constitute the top portion 111 of the top shelf 11, and two first cross members 114 and two first longitudinal members 113 cooperate to constitute the bottom portion 112 of the top shelf 11.

Therefore, by changing the heights of the first longitudinal beam 113 and the first cross beam 114, the height of the top frame 11 is entirely greater than the height of the bottom frame 12, so that the top frame 11 can be stretched to form a certain vertical space, which is beneficial to the following first subspace 141 surrounded by the bottom 112 of the top frame 11, the upright column 13 and the bottom frame 12. With this arrangement, the top frame 11 can be deformed to have a structural condition for dividing the internal space of the prefabricated module unit 100, and the structure is simple and reliable.

In yet another possible embodiment, in the top shelf 11, the height of each of the two first longitudinal beams 113 is greater than the height of one of the two first transverse beams 114 and equal to the height of the other of the two first transverse beams 114. The height of each first longitudinal beam 113 in the top shelf 11 is greater than the height of the corresponding second longitudinal beam 121 in the bottom shelf 12, and the height of each first cross beam 114 in the top shelf 11 is greater than or equal to the height of the corresponding second cross beam 122 in the bottom shelf 12, wherein the height is a dimension parallel to the direction of the vertical column 13. That is, in the top shelf 11, two first longitudinal beams 113 and one first cross beam 114 cooperate to constitute the top portion 111 of the top shelf 11, and two first longitudinal beams 113 and one first cross beam 114 cooperate to constitute the bottom portion 112 of the top shelf 11.

In addition, the height of one of the first beams 114 is smaller than that of the other first beam 114, so that the first beam 114, the upright column 13 and the first longitudinal beam 113 jointly form an opening entering the first subspace 141, and a certain moving space and a guiding function can be provided for arrangement of various wires in a ventilation pipeline, a wire frame, a cable, a bus, an exhaust system, a refrigeration system and an electric power system, so that various devices can smoothly enter the bottom 112 of the top layer frame body 11, the upright column 13 and the first subspace 141 enclosed by the bottom layer frame body 12 from the end surface of the prefabricated module unit 100, and the space arrangement inside the prefabricated module unit 100 is favorably and reasonably utilized.

It should be noted that, considering the bending of the beam, when changing the height of the beam constituting the top frame 11, the change of the height of the beam arranged in the long side direction, i.e., the first longitudinal beam 113, is to be considered preferentially, but does not represent that in some application scenarios, the change of the height of the beam arranged in the short side direction, i.e., the first transverse beam 114, cannot be considered preferentially, and the arrangement that the height of the beam of the top frame 11 can be changed and the height of the beam of the top frame 11 is greater than the height of the beam of the bottom frame 12 is within the protection scope of the embodiments of the present application, which is not strictly limited.

Based on the above description, it should be understood that, in the embodiment of the present application, the height of the top frame body 11 is greater than that of the bottom frame body 12 mainly by making the heights of the beams constituting the bottom frame body 12 equal, and making the height of at least one pair of side beams of the four beams constituting the top frame body 11 greater than that of each beam of the bottom frame body 12, so that the accommodating space 14 can be divided into two parts, which is beneficial to improve the space utilization rate inside the prefabricated module unit 100. Wherein, the height of the top shelf 11 is the distance from the top 111 to the bottom 112 of the top shelf 11, that is, the farthest distance from one end to the other end of the top shelf 11 in the direction parallel to the upright 13, which may be equal to the height of the first subspace 141.

In a possible embodiment, as shown in fig. 8, the prefabricated module unit may further include a partition 20, and the partition 20 is connected to the bottom 112 of the top shelf 11 to further facilitate the division of the receiving space 14 by the spacing function of the partition 20.

Referring to fig. 9 and 10, in the embodiment of the present application, the first longitudinal beam 113 may be a solid structure, that is, the first longitudinal beam 113 itself is a solid structure without a hollow area except for a hole-type structure or a groove-type structure for installation and positioning on the first longitudinal beam 113. Therefore, on the one hand, the first longitudinal beams 113 are not provided with complicated structures, the whole process is simple, and the whole processing and production efficiency of the frame 10 can be improved. On the other hand, the overall strength of the first longitudinal beam 113 is more excellent, which is beneficial to ensuring the overall yield strength of the frame 10, so that the frame 10 is not easy to bend and deform, and further the overall mechanical strength of the prefabricated module unit 100 is improved, and the prefabricated module unit is more suitable for outdoor scenes with complicated and changeable environmental conditions, and is beneficial to improving the application requirements of the prefabricated module unit 100 under multiple scenes.

Of course, the first longitudinal beam 113 may also be a hollow structure, that is, one or more hollow areas C may be disposed on the first longitudinal beam 113. Through setting up first longeron 113 into hollow out construction, can reduce first longeron 113's material manufacturing cost and administrative cost on the basis of guaranteeing whole mechanical strength, be favorable to improving production efficiency, can also make first longeron 113 highly on the basis of satisfying the demand, have diversified structural deformation probably, be favorable to adapting to prefabricated modular unit 100's multi-scene application demand.

The following description will be made of the implementation possibility of the first longitudinal beam 113 by taking the first longitudinal beam 113 as a hollow structure as an example, but it should be understood that the invention is not limited thereto.

Referring to fig. 10, 11, 12 and 13, each first longitudinal beam 113 includes a first layer frame 115, a second layer frame 116 and a web structure 117. Two adjacent first cross beams 114 are connected to the first-layer frame body 115, two adjacent upright posts 13 are stacked and connected to the second-layer frame body 116 and the first-layer frame body 115, the web member structure 117 is connected between the first-layer frame body 115 and the second-layer frame body 116, and a hollow area C is formed in a gap area between the web member structure 117 and the first-layer frame body 115 as well as between the web member structure 117 and the second-layer frame body 116.

It will be appreciated that the first tier frame 115 cooperates with the first cross member 114 to form the top 111 of the top tier frame 11 and the second tier frame 116 forms the bottom 112 of the top tier frame 11. The first-layer frame body 115 and the second-layer frame body 116 are arranged at intervals, and the distance between the first-layer frame body 115 and the second-layer frame body 116 can determine the height of the first longitudinal beam 113, specifically, the larger the distance between the first-layer frame body 115 and the second-layer frame body 116 is, the higher the height of the first longitudinal beam 113 is, the smaller the distance between the first-layer frame body 115 and the second-layer frame body 116 is, and the lower the height of the first longitudinal beam 113 is. The height of the first longitudinal beam 113 determines the proportion of the first sub-space 141 in the accommodating space 14, and specifically, the higher the height of the first longitudinal beam 113 is, the higher the specific gravity of the first sub-space 141 in the accommodating space 14 is, the lower the height of the first longitudinal beam 113 is, and the lower the specific gravity of the first sub-space 141 in the accommodating space 14 is.

Therefore, the height of the first longitudinal beam 113 can be flexibly adjusted by adjusting the spacing distance between the first layer frame body 115 and the second layer frame body 116, so that the proportion of the first sub-space 141 in the accommodating space 14 can be adjusted, the internal space of the prefabricated module unit 100 can be reasonably utilized, and the space utilization rate is high. And web member structure 117 is connected between first layer support body 115 and second layer support body 116, can make first layer support body 115 and second layer support body 116 connect each other through web member structure 117's connection effect, and then when first layer support body 115 atress, the power can be passed through web member structure 117 and transmitted on second layer support body 116, and then make second layer support body 116 can share the atress for first layer support body 115, thereby guarantee that first longeron 113 wholly possesses better structural stability, the reliability is good. And the hollow-out area C formed between the web member structure 117 and the first layer frame body 115 and the second layer frame body 116 can reduce the production cost of the first longitudinal beam 113 to the maximum extent on the basis of ensuring the strength of the first longitudinal beam 113, which is beneficial to improving the overall production efficiency of the prefabricated module unit 100.

Illustratively, the spacing between the first layer of shelves 115 and the second layer of shelves 116 is in the range of 300mm to 900mm (inclusive of 300mm and 900 mm). It can be understood that when the distance between the first-layer frame body 115 and the second-layer frame body 116 is too large, the proportion of the first sub-space 141 occupying the accommodating space 14 is increased, and the activity space of the worker and the installation space of the function module are reduced. When the distance between the first-layer frame body 115 and the second-layer frame body 116 is too small, the proportion of the first sub-space 141 occupying the accommodating space 14 is reduced, so that the first sub-space 141 does not have enough space size to accommodate one or more combinations of an exhaust system, an electric system, a refrigeration system, cables and wire racks. The distance between the first-layer frame body 115 and the second-layer frame body 116 is set in the range, so that the proportion of the first sub-space 141 and the second sub-space 142 occupied by the accommodating space 14 can be well balanced, and the possibility of space waste caused by insufficient space utilization of the prefabricated module unit 100 due to the fact that one of the sub-spaces occupies the accommodating space 14 in an excessively large or excessively small proportion is reduced to the minimum, so that the space in the prefabricated module unit 100 is better utilized.

In a possible embodiment, the extension direction of the web structure 117 is inclined to the extension direction of the first-layer frame body 115, which is equivalent to the extension direction of the web structure 117 also being inclined to the extension direction of the second-layer frame body 116. The inclined web member structure 117 can enable diversified connection relations to be achieved between the first layer frame body 115 and the second layer frame body 116, the inclined angle between the web member structure 117 and the first layer frame body 115 or the second layer frame body 116 can be adjusted according to different application scenes, and application requirements under multiple scenes can be improved.

That is, the web member structure 117 and the first layer frame body 115 are arranged at an included angle, which is equivalent to the included angle between the web member structure 117 and the second layer frame body 116, and the included angle is in an angle range of 30 degrees to 90 degrees (including 30 degrees and 90 degrees of end points). Therefore, when the web member structure 117 and the first layer frame body 115 are in the range of 30 degrees to 90 degrees, the load can be uniformly distributed on the first longitudinal beam 113, and the force applied to the first longitudinal beam 113 is uniform. When the included angle between the web member structure 117 and the first layer frame body 115 exceeds this range, the web member structure 117 may be insufficiently stressed or deformed, and the anti-seismic effect is poor.

For example, as shown in fig. 11 and 13, the extension direction of the web member structure 117 is perpendicular to the extension direction of the first-layer frame body 115, so that the force applied to the first-layer frame body 115 can be transmitted to the second-layer frame body 116 at the shortest distance, and the distance required for transmitting the force can be shortened, which is highly practical. Alternatively, as shown in fig. 12 and 14, the extending direction of the web member structure 117 and the extending direction of the first layer frame body 115 form an angle in the range of 30 ° to 60 ° (including 30 ° and 60 ° as end points) to well meet the application requirements in multiple scenarios.

In the embodiment of the present application, as shown in fig. 11, the number of the web structures 117 may be one, and one web structure 117 may be vertically disposed between the first-layer frame body 115 and the second-layer frame body 116, so that the first-layer frame body 115, the web structure 117, and the second-layer frame body 116 are connected to form an "i" shaped structure, or, as shown in fig. 12, one web structure 117 may also be obliquely disposed between the first-layer frame body 115 and the second-layer frame body 116, so that the first-layer frame body 115, the web structure 117, and the second-layer frame body 116 are connected to form a "Z" shaped structure.

Alternatively, referring to fig. 10, 13 and 14, the web structure 117 may also include a plurality of substructures 118, each of the substructures 118 is connected between the first-layer frame body 115 and the second-layer frame body 116, and two adjacent substructures 118 may be spaced apart from each other or connected to each other. Providing a plurality of substructures 118 and dispersing the plurality of substructures 118 at various positions between the first-layer frame body 115 and the second-layer frame body 116 enables the substructures 118 capable of converting stress to be provided at various positions on the first-layer frame body 115. Therefore, balanced connection can be provided for the first layer frame body 115 and the second layer frame body 116, so that the load of the first longitudinal beam 113 is uniformly distributed on the first layer frame body, the whole stress is uniform, the better bending resistance of the prefabricated module unit 100 is realized, and the situation that the prefabricated module unit 100 fails due to weak connection strength at a certain position of the first longitudinal beam 113 can be prevented from occurring when an earthquake occurs.

Illustratively, as shown in fig. 13 and 14, the extending directions of two adjacent substructures 118 may be arranged in parallel. Alternatively, as shown in fig. 10, the extending directions of two adjacent substructures 118 may intersect. It should be understood that fig. 10 only schematically shows the possibility of intersecting the extending directions of two adjacent sub-structures 118, the angle of the included angle between two adjacent sub-structures 118 may be in the range of 0 ° to 180 ° (including the endpoint values of 0 ° and 180 °), and a V-shaped symmetrical or asymmetrical structure may be present, which is not strictly limited.

It should be noted that, in consideration of the stress balance between the two first longitudinal beams 113, as described above, the two first longitudinal beams 113 have the same form and structure, but in the practical application of the prefabricated module unit 100, the form and structure of the two first longitudinal beams 113 may also be different, for example, the connection positions and the number of the web member structures 117 disposed between the first layer frame body 115 and the second layer frame body 116 may be different, as long as the height of the first longitudinal beam 113 is greater than the height of the second longitudinal beam 121, which is not strictly limited. In addition, the first longitudinal beam 113 may be provided as a beam structure having a string structure, that is, the second-layer frame 116 may not be connected between two adjacent vertical columns 13, but may be located only between the first-layer frame 115 and the bottom-layer frame 12.

In one possible embodiment, as shown in fig. 15 and 16, the prefabricated modular units 100 further comprise a connecting structure 50, the connecting structure 50 is connected to the top 111 of the top shelf 11, i.e., the first-layer shelf 115, through a guide post, and the connecting structure 50 is used for connecting two adjacent prefabricated modular units 100. Because the connecting structure 50 is an independent structure, the connecting structure 50 is connected to the first-layer frame body 115, when a plurality of prefabricated module units 100 are vertically stacked, a gap can be formed between two adjacent prefabricated module units 100 through the spacing effect of the connecting structure 50, and the size of the gap can be designed according to the thickness of the connecting structure 50, the overall strength of the data center 200, the size of the space of the application data center 200 and other factors, so that the size is not strictly limited.

Illustratively, the connecting structure 50 is provided with a guide hole 51, and when two prefabricated modular units 100 are vertically stacked, two adjacent prefabricated modular units 100 can be connected to each other by punching a positioning hole 119 on the first longitudinal beam 113 (specifically, the first-layer frame body 115) of the prefabricated modular unit 100 located below and the bottom-layer frame body 12 of the prefabricated modular unit 100 located above, and aligning the guide hole 51 with the positioning hole 119, thereby enabling the connection of the guide columns. When two prefabricated modular units 100 are transversely spliced, the guide holes 51 may be aligned with the positioning holes 119 by punching the positioning holes 119 into the first longitudinal beams 113 (specifically, the first-layer frame bodies 115) of two prefabricated modular units 100, respectively, and placing the connecting structure 50 on the first-layer frame bodies 115 of two adjacent prefabricated modular units 100, so that the two adjacent prefabricated modular units 100 can be connected to each other through the connection of the guide columns. With the arrangement, the fixing mode is simple, the cost is low, and the operation is convenient. Wherein, the guide post can be a bolt.

It should be noted that, the number of the connecting structures 50 may be one or more, and when there are a plurality of connecting structures 50, the plurality of connecting structures 50 may be distributed at intervals at various positions on the first longitudinal beam 113 (specifically, on the first-layer frame body 115), and may provide a balanced connection for the first longitudinal beam 113, so as to enhance the connection strength at various positions of the first longitudinal beam 113, and avoid concentrated force transmission caused by concentrated arrangement of the connecting structures 50, which may cause damage to the prefabricated module unit 100 and affect the stability of the data center 200. The size of the coupling structure 50 can be adjusted according to the coupling manner of the transverse assembling and the longitudinal stacking, and as shown in fig. 15 and 17, when the coupling structure 50 is to be stacked with two prefabricated module units 100 in the vertical direction, the size of the coupling structure 50 can be set to be correspondingly small. As shown in fig. 16 and 18, when the connecting structure 50 is to be used to transversely assemble two prefabricated modular units 100, the size of the connecting structure 50 can be set to be correspondingly large. That is, the size of the connecting structure 50 can be flexibly adjusted according to actual conditions, and is not strictly limited thereto.
