TECHNICAL FIELD
[0001] The utility model relates to data center energy saving technical field, especially a prefabricated modular container type data center. BACKGROUND
[0002] The prefabricated modular data center is a pre-engineering scheme product, which is used for integrating information technology equipment (such as servers, switches, firewalls, etc.), supporting power supply and distribution, refrigeration, fire control, monitoring and other equipment into a modular container body in a factory according to project requirements, and then transporting the container body to a project site for reassembly and use.
[0003] Container roof waterproofing is one of the most important factors affecting the use function of the building, and is also a weak link in the building. A large number of high-value, precision equipment are placed in the data center, which is sensitive to the environment and expensive, so the roof waterproofing is particularly important for the prefabricated modular data center project, and the loss and consequences are very serious once the waterproofing fails.
[0004] The prefabricated modular data center is composed of different modular containers, and the roof is composed of the top plates of different containers and the joints between the top plates. The numerous joints and difficult drainage are the "pain points" of the prefabricated modular data center roof. Due to the lack of reliable and durable joint sealing nodes and effective roof drainage measures, a general prefabricated modular data center needs to build a "herringbone" roof on the container module roof to achieve the standard drainage slope and roof waterproofing requirements through building slope. The "herringbone" roof solves the problems of roof drainage and waterproofing of the prefabricated modular data center, but the construction is complex and the construction period is long, which offsets the advantages of rapid deployment of the prefabricated modular data center, and also causes the problems of cost increase and poor resistance to typhoon, so the "herringbone" roof is not a good solution to the roof drainage and waterproofing problems of the prefabricated modular container type data center.
[0005] In order to reduce the use cost and shorten the construction time while meeting the functional requirements of roof drainage and waterproofing, the utility model provides a prefabricated modular container type data center. SUMMARY

[0015] The connection between the drainage eaves and the cap brim adopts a 360° interlocking design, and the fixed support and waterstop are connected to the container body by single-sided bolt fasteners.
[0016] The waterstop is a water-absorbing and expanding rubber waterstop, and the outer layer of the water-absorbing and expanding rubber waterstop is covered with butyl non-drying sealant.
[0017] The joint filling structure comprises three layers from bottom to top: foam rods, rock wool strips, and non-cured rubber asphalt.
[0018] Among them, foam rods and non-cured rubber asphalt are used to seal the upper and lower ends of the joint, respectively, rock wool strips are used for heat insulation, and foam rods are also used to support rock wool strips.

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0029] This prefabricated modular containerized data center includes container bodies. The top plate of the top container body has a 2% one-way slope. When two top container bodies are spliced side by side, a sharp corner is formed at the connection point.
[0030] Taking a 40-foot container as an example, the height of the two pillars at one end of its length is 4150mm, and the height of the two pillars at the other end is reduced to 3900mm. After the container roof is covered, the container roof has a 2% slope.
[0031] There are three types of container combinations: single-row single-slope, double-row double-slope without corridor, and double-row double-slope with corridor. All three types of container combinations have a roof with a 2% structural slope, which can meet the roof drainage slope requirements.
[0032] The joint where the two top-level container bodies are spliced side by side is equipped with a joint sealing structure;
[0033] The joint sealing structure includes, from top to bottom, a drainage structure, a waterstop strip, and a joint filling structure 7;
[0034] The joint filling structure 7 is located between the two container bodies, and the drainage structure and waterstop are connected to the container bodies by single-sided bolt fasteners 3.
[0035] The drainage structure includes a seam cap 1 and a C-shaped fold 2. The seam cap 1 and the C-shaped fold 2 are connected at the eaves with a 360° interlocking design and are connected by stainless steel rivets to ensure that no water seepage channels are formed.
[0036] The seam cap 1 includes a cap top and a cap brim. The cap top has an inverted V-shaped structure and both sides have a 10% slope.
[0037] The C-shaped folding piece 2 is used to support the seam cap 1, including a fixed support and a drainage eaves;
[0038] The connection between the drainage eaves and the cap brim adopts a 360° interlocking design, and the fixed support and waterstop are connected to the container body by a single-sided bolt fastener 3.
[0039] The waterstop is a water-absorbing and expanding rubber waterstop 4, and the outer layer of the water-absorbing and expanding rubber waterstop 4 is covered with butyl non-drying sealant 5.
[0040] The joint filling structure 7 comprises, from bottom to top, a three-layer structure consisting of foam rods, rock wool strips, and non-cured rubber asphalt;
[0041] Among them, foam rods and non-cured rubber asphalt are used to seal the upper and lower ends of the joint, respectively, rock wool strips are used for heat insulation, and foam rods are also used to support rock wool strips.
[0042] The top-level container body splicing area is equipped with longitudinal and transverse frame beams 6. The fixed supports and waterstops of the C-shaped folding parts 2 are connected to the longitudinal and transverse frame beams 6 by single-sided bolt fasteners 3.
[0043] The drainage eaves of the C-shaped folding piece 2 and the brim of the spliced cap 1 are both 50mm wide.
[0044] The foam rod has a diameter of 40mm and the rock wool strip has a thickness of 100mm.
[0045] The C-type folding member 2 is made of 3.0mm thick high-weather-resistant stainless steel, folded into the required shape at the factory. The width of the web of the C-type folding member 2 is the sum of the flange width and the joint width of the box girder plus 20mm. The C-type folding member 2 extends outward by 50mm on each side to provide joint cap fixing supports and drainage eaves. The web of the C-type folding member 2 is clamped to the lower water-absorbing and expanding rubber waterstop 4 by 4*M12 stainless steel bolts arranged at 500mm intervals. It is connected to the upper flange plate of the longitudinal and transverse frame beams of the box girder. The pre-tension provided by the bolts compresses the water-absorbing and expanding rubber waterstop 4 in the web of the C-type folding member 2, so that the waterstop is tightly fitted to the web of the C-type folding member 2 and the upper flange plate of the beam.
[0046] The water-absorbing and swelling rubber waterstop 4 is an intelligent waterproof material combining the elasticity of rubber and the properties of water-absorbing resin. Applicable to sealing the joints of prefabricated modular data center roofs, the water-absorbing and swelling rubber waterstop 4 has a specially designed shape. The upper and lower surfaces of the waterstop are corrugated with a peak height of 0.2mm and a wave pitch of 0.5mm. The middle of the waterstop contains a hollow tube 42 with an inner diameter of 4mm and a wall thickness of 4mm. The thickness of the waterstop 4 is 4mm, and its width equals the flange width of the girder plus the joint width. A layer of butyl self-adhesive 5 is applied to the upper and lower surfaces of the water-absorbing and swelling rubber waterstop 4. The pre-tension provided by bolts compresses the web of the C-shaped fold 2, reducing the thickness of the water-absorbing and swelling rubber waterstop 4 from 4mm to 2mm, ensuring a tight fit between the water-absorbing and swelling rubber waterstop 4 and the web of the C-shaped fold 2 and the upper flange of the beam. Any gaps remaining between the water-absorbing and swelling rubber waterstop 4 and the web of the C-shaped fold 2 and the upper flange of the beam can be actively filled and sealed due to its water-swelling properties.
[0047] The seam cap 1 is made of high weather-resistant stainless steel, which has good durability and a wall thickness of 1mm. It is folded at a 10% slope in the factory. With its built-in 10% slope 11 and 50mm wide eaves 12, it has excellent drainage performance at the seam, with a low possibility of water accumulation, reducing the pressure on the seam waterproofing and realizing the design concept of "combining prevention and drainage".
[0048] The single-sided bolt fastener 3, made of high weather-resistant stainless steel, is 12mm in diameter and 50mm in length. It is pre-tapping the flange plates of the longitudinal and transverse frame beams 6 of the box body to secure the bolts. The tapping diameter, quantity, position, and spacing match the bolt arrangement on the C-shaped fold 2. The single-sided bolt fastener 3 provides the pre-pressure required for compressing the water-absorbing and expanding rubber waterstop 4 and secures the C-shaped fold 2.
[0049] Butyl non-drying sealant 5 uses butyl rubber (IIR) or halogenated butyl rubber as a base material, and features no curing required and permanent plasticity. It is used at the connection between the joint cap 1 and the C-shaped fold 2, and on the upper and lower surfaces of the water-absorbing and expanding rubber waterstop 4. Through the extrusion pressure during connection, butyl non-drying sealant 5 can fill the gaps in the contact surface and block leakage channels.
[0050] The embodiments described above are merely one specific implementation of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
