Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation ducts, in particular to a special vertical shaft exhaust duct reinforcement structure for a data center computer room building. Background Art

[0002] In the ventilation system of computer room buildings such as data centers, the shaft exhaust ducts installed outside the computer room buildings play a vital role in exhausting hot air. In addition to being installed in mounting structural beams such as steel structural beams, existing shaft ventilation ducts are often reinforced by welding metal strips on the outside of the ventilation ducts, but this method has the problem of limited reinforcement effect. There are also structures that reinforce the ventilation ducts by setting annular metal rings around them. However, this structure is prone to loosening and deformation when dealing with strong winds or long-term use. Therefore, the existing reinforcement method of the shaft exhaust ducts outside the computer room buildings of data centers still needs to be improved in terms of stability, durability and installation convenience to meet the growing ventilation needs of computer rooms.

The shaft exhaust duct 1 is provided with a corresponding number of hot air inlets 4 corresponding to the hot air exhaust outlets of the computer room building 3 on each floor. The shaft exhaust duct 1 is provided with a set of reinforcement units 6 on the lower and upper outer surfaces on each floor, namely a bottom support reinforcement unit 6.1 and an upper support reinforcement unit 6.2;

[0006] The reinforcement unit 6 includes two reinforcement frames 7 arranged in an upper and lower manner for being sleeved on the outer ring of the flange air duct 5. The reinforcement frame 7 is composed of four C-shaped steels 9 with bolt mounting holes 8 evenly arranged at the bottom of the groove. The four C-shaped steels 9 are the first, second, third and fourth C-shaped steels 9.1, 9.2, 9.3 and 9.4 respectively. The second C-shaped steel 9.2 is located on the side of the shaft exhaust air duct 1 facing the machine room building 3.

Outside the reinforcement frame 7, the ends of the two reinforcement frames 7 protruding from the reinforcement frame are arranged correspondingly up and down, and the two reinforcement frames 7 are connected by four vertical C-shaped steels 10 perpendicular to the reinforcement frame 7, and one end of the vertical C-shaped steel 10 is vertically connected to the end of a reinforcement frame protruding from the reinforcement frame 7 of the two reinforcement frames near the middle of the floor; at least one of the positions where the two ends of the vertical C-shaped steel 10 meet the two reinforcement frames 7 is connected by an angle connector 11, and the angle connectors 11 are fixed together with the vertical C-shaped steel 10 and the reinforcement frame 7 by full welding;

[0007] The four ends of the reinforcement frame 7 protruding from the upper end of the upper support reinforcement unit 6.2 are mounted above the installation structure beam 2 of the upper layer and are fixed to the installation structure beam 2 of the upper layer by full welding; the four ends of the reinforcement frame 7 protruding from the lower end of the bottom support reinforcement unit 6.1 are mounted above the installation structure beam 2 of this layer or the ground, and are fixed to the installation structure beam 2 of this layer or the ground by full welding, so as to allow the vertical C-shaped steel 10 in the middle to pull or lift up another reinforcement frame 7 near the middle of the floor and away from the supporting beam body of the installation structure beam 2; the shaft exhaust duct 1 is at the junction of the two layers, the bottom support reinforcement unit 6.1 on the upper side and the upper support reinforcement unit 6.2 on the lower side share a reinforcement frame body, that is, the reinforcement frame 7 at the lower end of the bottom support reinforcement unit 6.1 of the upper layer and the reinforcement frame 7 at the upper end of the upper support reinforcement unit 6.2 of the lower layer share the same reinforcement frame body.

[0008] Preferably, the four C-shaped steels 9 constituting the reinforcement frame 7 are fixed at their intersections by full butt welding.

[0009] Preferably, each C-shaped steel 9 of the reinforcement frame 7 is fastened and fixed to the outer side surface of the flange air duct 5 by a plurality of sets of evenly distributed fasteners 13 .

[0010] Preferably, the fastener 13 includes bolts, nuts and washers that cooperate with each other. During installation, the bolts are driven through the duct plate from the inside of the duct to the outside, through the bolt mounting holes 8 on the C-shaped steel 9, and then the C-shaped steel 9 and the flange duct 5 are fastened together with nuts and washers.

[0011] Furthermore, the spacing between each set of fasteners 13 is 20-40 cm.

[0012] Preferably, the C-shaped steel 9 is a channel-shaped structure with curled edges on both ends, and is formed by folding steel bars.

[0013] Preferably, the outer layers of each C-shaped steel 9 and vertical C-shaped steel 10 forming the reinforcement frame 7 are coated with an anti-corrosion nanofilm, which can be a polymer, metal, or ceramic film. This anti-corrosion nanofilm not only prevents corrosion but also helps maintain the original color of the reinforcement unit during long-term use.

[0014] Preferably, except for the vertical shaft exhaust duct 1 located on the bottom floor, the fourth C-shaped steel 9.4 on the reinforcement frame 7 on the reinforcement unit 6 installed on the vertical shaft exhaust duct 1 on the remaining floors has several horizontal C-shaped steels 12 extending vertically outward and parallel to the reinforcement frame. The horizontal C-shaped steel 12 and the C-shaped steel 9 on the reinforcement frame 7 are connected by full welding or direct full welding after connection with an angle connector 11.

[0016] Preferably, the flange duct 5 is an angle iron flange duct or an aluminum alloy thermal break flange duct. More preferably, in places where installation is convenient and strength is not particularly high, the aluminum alloy thermal break flange duct is used, because the external aluminum alloy thermal break flange is cheap, cost-saving, and can be sprayed with colored paint on its outer side as needed, so as to maintain the uniform appearance of the overall duct. In places where installation is inconvenient, such as where there is only a structural beam installed but no top-level overhead layer with a support grid for people to walk on, and where it is inconvenient for people to stand, and where strength is required, such as an air duct with a larger inner diameter at the top, where the hoisting weight is heavy, and where there is a risk of falling off between the air ducts during hoisting, the angle iron flange duct is used, because although the angle iron flange is more expensive than the external aluminum alloy thermal break flange, it only needs to tighten the bolts during installation, which is convenient for installation, has high installation efficiency, is easy to ensure the safety of the installer, and has high connection strength and good hoisting safety.

[0017] Preferably, two folding connectors 14 with bolt holes on both sides are vertically connected on the inner wall of the connection between at least partially adjacent two sections of flange duct 5 on the uppermost vertical shaft exhaust duct 1. The two folding connectors 14 are respectively located at diagonal positions in the flange duct. Each folding connector is fixed to the two side walls of the flange duct by fasteners to enhance the connection strength between the two sections of flange duct and ensure installation strength and hoisting safety. More preferably, the fasteners include bolts, nuts and washers that cooperate with each other. During installation, after the bolts pass through the bolt holes on the folding connectors 14 and penetrate the duct plate from the inside of the flange duct to the outside, the folding connectors 14 and the flange duct 5 are fastened together using nuts and washers.

[0034] like Figure 1-11 As shown, a dedicated vertical shaft exhaust duct reinforcement structure for a data center computer room building is provided. The vertical shaft exhaust duct 1 is one floor higher than the computer room building 3 and is supported by installing structural beams 2 on each floor. In this embodiment, the computer room building has five floors, and the vertical shaft exhaust duct 1 is six floors high. The vertical shaft exhaust duct 1 is composed of a plurality of flange ducts 5 with gradually increasing cross-sectional areas from bottom to top, which are spliced ​​together to meet the increasing air output requirements as the number of computer room floors increases. The vertical shaft exhaust duct 1 is provided with a corresponding number of hot air inlets 4 corresponding to the hot air exhaust outlets of the computer room building 3 on each floor. The vertical shaft exhaust duct 1 is provided with a group of reinforcement units 6 on the lower and upper outer surfaces on each floor, namely a bottom support reinforcement unit 6.1 and an upper support reinforcement unit 6.2.

[0035] The reinforcement unit 6 includes two reinforcement frames 7 arranged in an upper and lower manner for being sleeved on the outer ring of the flange air duct 5. The reinforcement frame 7 is composed of four C-shaped steels 9 with bolt mounting holes 8 evenly arranged at the bottom of the groove. The four C-shaped steels 9 are the first, second, third and fourth C-shaped steels 9.1, 9.2, 9.3 and 9.4 respectively. The second C-shaped steel 9.2 is located on the side of the shaft exhaust air duct 1 facing the machine room building 3. The first and third C-shaped steels 9.1 and 9.3 are located on both sides of the side of the shaft exhaust air duct 1 facing the machine room building 3, and both ends of the first and third C-shaped steels 9.1 and 9.3 protrude. Outside the reinforcement frame 7, the ends of the two reinforcement frames 7 protruding from the reinforcement frame are arranged correspondingly up and down, and the two reinforcement frames 7 are connected by four vertical C-shaped steels 10 perpendicular to the reinforcement frame 7, and one end of the vertical C-shaped steel 10 is vertically connected to the end of a reinforcement frame protruding from the reinforcement frame 7 of the two reinforcement frames near the middle of the floor; at least one of the positions where the two ends of the vertical C-shaped steel 10 meet the two reinforcement frames 7 is connected by an angle connector 11, and the angle connectors 11 are fixed together with the vertical C-shaped steel 10 and the reinforcement frame 7 by full welding;

[0036] The four ends of the reinforcement frame 7 protruding from the upper end of the upper support reinforcement unit 6.2 are mounted above the installation structure beam 2 of the upper layer and are fixed to the installation structure beam 2 of the upper layer by full welding; the four ends of the reinforcement frame 7 protruding from the lower end of the bottom support reinforcement unit 6.1 are mounted above the installation structure beam 2 of this layer or the ground, and are fixed to the installation structure beam 2 of this layer or the ground by full welding, so as to allow the vertical C-shaped steel 10 in the middle to pull or lift up another reinforcement frame 7 near the middle of the floor and away from the supporting beam body of the installation structure beam 2; the shaft exhaust duct 1 is at the junction of the two layers, the bottom support reinforcement unit 6.1 on the upper side and the upper support reinforcement unit 6.2 on the lower side share a reinforcement frame body, that is, the reinforcement frame 7 at the lower end of the bottom support reinforcement unit 6.1 of the upper layer and the reinforcement frame 7 at the upper end of the upper support reinforcement unit 6.2 of the lower layer share the same reinforcement frame body.

[0037] The four C-shaped steels 9 constituting the reinforcement frame 7 are fixed at their intersections by full butt welding.

[0038] The C-shaped steels 9 of the reinforcement frame 7 are fastened and fixed to the outer side surface of the flange air duct 5 by a plurality of sets of evenly distributed fasteners 13 .

[0039] The fasteners 13 include bolts, nuts and washers that cooperate with each other. During installation, the bolts are driven from the inside of the duct to the outside through the duct plate, through the bolt mounting holes 8 on the C-shaped steel 9, and then the C-shaped steel 9 and the flange duct 5 are fastened together with nuts and washers.

[0040] The spacing between each set of fasteners 13 is 20-40 cm.

[0041] The C-shaped steel 9 is a channel-shaped structure with curled edges at both ends, and is formed by folding a steel bar.

[0042] Each C-shaped steel 9 and vertical C-shaped steel 10 that makes up the reinforcement frame 7 is coated with an anti-corrosion nanofilm, which can be made of a polymer, metal, or ceramic film. This nanofilm not only prevents corrosion but also helps the reinforcement unit maintain its original color over long-term use.

[0043] Except for the vertical shaft exhaust duct 1 located on the bottom floor, the fourth C-shaped steel 9.4 on the reinforcement frame 7 on the reinforcement unit 6 installed on the vertical shaft exhaust duct 1 on the remaining floors has several horizontal C-shaped steels 12 extending vertically outward and parallel to the reinforcement frame. The horizontal C-shaped steel 12 and the C-shaped steel 9 on the reinforcement frame 7 are connected by full welding or direct full welding butt connection after being connected with an angle connector 11. The other end of the horizontal C-shaped steel 12 is fixedly connected to the mounting structure beam 2 of the layer by full welding or direct full welding butt connection after being connected with an angle connector 11.

Preferably, the spacing of the bolt holes 11.3 matches the spacing of the bolt mounting holes 8 provided on the channel bottoms of the C-shaped steels 9 that comprise the reinforcement unit 6.

[0045] The flange air duct 5 is an angle iron flange air duct or an aluminum alloy thermal break flange air duct. Preferably, in places where installation is convenient and strength is not particularly high, the aluminum alloy thermal break flange air duct is used, because the external aluminum alloy thermal break flange is cheap, cost-saving, and can be sprayed with colored paint on its outer side as needed, so as to maintain the uniform appearance of the air duct as a whole. In places where installation is inconvenient, such as where there is only an installation structure beam and no top-level overhead layer with a support grid for people to walk on, and where it is inconvenient for people to stand, and where strength is required, such as in the upper part of the air duct with a larger inner diameter, where the hoisting weight is heavy, and where there is a risk of falling off between the air ducts during hoisting, the angle iron flange air duct is used. Although the angle iron flange is more expensive than the external aluminum alloy thermal break flange, it only needs to tighten the bolts during installation, which is convenient for installation and operation, with high installation efficiency and easy to ensure the safety of the installer. It also has high connection strength and good hoisting safety. In this embodiment, the shaft exhaust duct 1 uses angle iron flange ducts on the top layer, i.e., the 6th layer, and also uses angle iron flange ducts on the higher 4th and 5th layers.

[0046] Two folding connectors 14 with bolt holes on both sides are vertically connected on the inner wall of the connection between at least partially adjacent two sections of flanged air duct 5 on the uppermost vertical shaft exhaust air duct 1. The two folding connectors 14 are respectively located at diagonal positions within the flanged air duct. Each folding connector is fixed to the two side walls of the flanged air duct by fasteners to enhance the connection strength between the two sections of flanged air duct, ensuring installation strength and lifting safety. More preferably, the fasteners include mutually cooperating bolts, nuts, and washers. During installation, the bolts pass through the bolt holes on the folding connectors 14 and then penetrate the air duct plate from the inside of the flanged air duct outward. After that, the folding connectors 14 and the flanged air duct 5 are fastened together using nuts and washers.

[0047] Installation process:

[0048] 1) After the production of each flange duct 5 constituting the shaft exhaust duct 1 is completed, four C-shaped steels are fixed to the outer surface of each flange duct where a reinforcement frame is required to be installed by fasteners 13 according to the actual size of the flange duct to form a reinforcement frame 7, wherein it is ensured that the shaft exhaust duct 1 is at the junction of the two layers, the bottom support reinforcement unit 6.1 on the upper side and the upper support reinforcement unit 6.2 on the lower side share a reinforcement frame body, that is, the reinforcement frame 7 at the lower end of the bottom support reinforcement unit 6.1 of the upper layer and the reinforcement frame 7 at the upper end of the upper support reinforcement unit 6.2 of the lower layer share the same reinforcement frame body to save materials and installation work; then the intersections between the four C-shaped steels are welded together,

[0049] 2) Except for the flange ducts on the shaft exhaust duct 1 on the bottom floor, which are directly spliced ​​and installed from the ground up, the flange ducts 5 on the shaft exhaust ducts 1 corresponding to the machine room buildings on other floors will be spliced ​​and fixed together in sequence or in several sections according to actual needs, and then lifted by a crane and placed from top to bottom into the installation structure beam 2, so that the installation structure beam 2 supports the flange duct 5 on each floor. During the hoisting, the crane rope is hung on the four protruding ends of the reinforcement frame; after being placed, the upper support reinforcement unit 6.2 is located at The four ends of the upper reinforcement frame 7 protruding from the reinforcement frame 7 are mounted above the mounting structure beam 2 of the upper layer, and then after leveling, the four ends of the reinforcement frame 7 are fixed to the mounting structure beam 2 of the upper layer by full welding; the four ends of the reinforcement frame 7 at the lower end of the bottom support reinforcement unit 6.1 protruding from the reinforcement frame 7 are mounted above the mounting structure beam 2 of the layer or the ground, and then after leveling, the four ends of the reinforcement frame 7 are fixed to the mounting structure beam 2 of the layer or the ground by full welding;

[0050] 3) Connect the protruding ends of the first and third C-shaped steels on the reinforcement frame 7 near the middle of the floor in the reinforcement unit 6 to the vertical C-shaped steel 10 through angle connectors. The angle connectors 11 are fixed to the vertical C-shaped steel and the reinforcement frame by full welding;

[0051] 4) The other end of the vertical C-shaped steel 10 is connected to the other reinforcement frame in the reinforcement unit by using an angle connector and then fully welded or directly fixed by fully welded, thereby completing the entire fixation.

A group of reinforcement units are provided on the outer sides of the lower and upper sides of each layer of the shaft exhaust duct. Compared with the existing support method, it can better provide uniform and stable supporting force for the duct, effectively disperse the gravity and wind force borne by the duct, thereby greatly improving the stability and durability of the duct, and extending the service life of the duct; and the reinforcement frame in the reinforcement unit can be pre-fixed on the outer surface of the flange duct before the flange duct is spliced ​​together, and combined with the ingenious, convenient and fast installation and fixing method between the two reinforcement frames in a reinforcement unit, the reinforcement frame can not only be flexibly made according to the actual size, so that it can fit tightly on the outer side of the duct, but also can be applied to shaft exhaust ducts of different specifications and shapes, so that it has a wide range of application prospects, and is easy to install, fast and accurate, with high construction efficiency and strong practicality, and is worthy of promotion.
