Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a spliced ​​air duct. Background Art

[0002] The air duct is a piping system used for air transportation and distribution. After the electromechanical pipeline professional integrated modules or the building modules pre-installed with electromechanical pipelines are stacked and assembled, the integrated air ducts between the integrated modules need to be connected, which involves the integrated air duct connection between the vertical integrated modules and the horizontal integrated modules.

[0003] In the process of connecting the integrated air ducts between the modules, the outer surface of the integrated air ducts for special purposes also needs to be covered with an insulation layer or a protective layer, such as air conditioning ducts or smoke exhaust ducts. When the size of the integrated air duct is slightly larger, workers cannot complete the back connection of the air duct and the installation of the insulation layer or the protective layer in the construction space on one side. In the prior art, the size of the connecting air duct is usually increased or reduced, so that it is pre-installed on one end of the integrated air duct and transported to the construction site together with the integrated air duct. The integrated air ducts between the modules are connected through the connecting air duct, and then the glue is injected to ensure the sealing connection between the integrated air duct and the connecting air duct. However, the integrated air duct and the connecting air duct are partially thick and cannot form a regular sealing gap, so the sealing of the integrated air duct cannot be guaranteed.

[0004] Therefore, a spliced ​​air duct is needed to at least partially solve the above problems. Utility Model Content

[0096] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0097] The utility model provides a spliced ​​air duct 100. For the specific structure of the spliced ​​air duct 100, please refer to Figures 1 to 34, which includes an integrated air duct 110 and a connecting member 120, wherein the two integrated air ducts 110 are arranged opposite to each other along a first direction D1, and connecting flanges 111 are arranged at opposite ends of the integrated air ducts 110; the connecting member 120 is constructed as a cylindrical structure with two open ends along the first direction D1, and the two open ends are respectively connected to the corresponding integrated air duct 110 via the connecting flanges 111, and the connecting member 120 includes a connecting component 121, and the connecting component 121 includes two ends opposite to each other in a circumferential direction, wherein the adjacent ends of at least two connecting components 121 are connected together so that at least two connecting components 121 surround the cylindrical structure, and the connection between the two connecting components 121 forms a connecting seam extending along the first direction D1; or the two ends of a connecting component 121 are connected together to surround the cylindrical structure, and the connection between the two ends forms a connecting seam extending along the first direction D1.

[0098] According to the spliced ​​air duct 100 of the utility model, two integrated air ducts 110 are connected by a connecting member 120, which reduces the difficulty of assembling the spliced ​​air duct 100 and shortens the installation period at the construction site. At the same time, a regular sealing gap is formed between the connecting member 120 and the integrated air duct 110, the adjacent connecting parts 121 or the two ends, ensuring that the spliced ​​air duct 100 has good sealing performance.

[0099] like Figure 2 , Figures 9 to 13 , Figures 18 to 22 , Figure 25 to Figure 28 , Fig.33 , Fig.34 As shown, the first direction D1 can be roughly parallel to the height direction of the spliced ​​air duct 100. Specifically, the two integrated air ducts 110 are arranged opposite to each other up and down, and the connecting flange 111 is sleeved on the outer periphery of the opposite ends of the integrated air duct 110 and extends outward laterally. Of course, the first direction D1 can also be roughly parallel to the length direction of the spliced ​​air duct 100. Specifically, the two integrated air ducts 110 are arranged opposite to each other left and right, and the connecting flange 111 is arranged on the outer periphery of the opposite ends of the integrated air duct 110 and extends outward longitudinally. For the convenience of description, in this embodiment, the first direction D1 is roughly parallel to the height direction of the spliced ​​air duct 100.

[0100] like Fig.10 , Fig.19 and Fig.26 As shown, for a spliced ​​air duct 100 for special purposes, such as air conditioning, smoke exhaust ducts and other devices, the spliced ​​air duct 100 also includes an insulation board 190, and the insulation board 190 is coated on the outer surface of the two integrated air ducts 110. The connecting member 120 and the insulation board 190 are arranged front and back. By arranging the insulation board 190, the heat loss can be reduced, the generation of condensed water can be reduced, and the service life of the spliced ​​air duct 100 can be extended.

[0101] The profile of the connecting member 120 matches the profile of the integrated air duct 110. Figures 2 to 12 , Fig.29 and Fig.30 As shown, the cross-sections of the integrated air duct 110 and the connecting member 120 are both polygonal, wherein the number of sides of the polygon is greater than or equal to 4; or Figures 13 to 28 , Figure 31 to Figure 34 As shown, the cross-sections of the integrated air duct 110 and the connecting component 120 are both circular or elliptical. Since the integrated air duct 110 and the connecting component 120 are both cylindrical structures, the spliced ​​air duct 100 obtained by splicing and assembling has no right-angle turning points. The air flow resistance in the spliced ​​air duct 100 is small, which can improve the ventilation efficiency. At the same time, the difficulty of splicing and assembling is low. A regular sealing gap is formed between the connecting component 120 and the integrated air duct 110, the adjacent connecting components 121 or the two ends, which can effectively avoid the hidden danger of leakage.

[0102] like Figures 1 to 6 , Figures 12 to 15 , Figure 21 to Figure 24 and Figures 28 to 34 As shown, the connection component 120 is provided with at least one branch pipe interface 122 , and the branch pipe is connected to the connection component 120 and communicates with the connection component 120 through the branch pipe interface 122 , so that the branch pipe communicates with the integrated air duct 110 through the connection component 120 .

[0103] Preferably, the connection seam between the open end of the connecting member 120 and the corresponding connecting flange 111 is filled with a flexible sealing material to ensure good sealing at the connection between the connecting member 120 and the integrated air duct 110, thereby preventing air leakage from the connection seam between the open end of the connecting member 120 and the corresponding connecting flange 111.

[0104] As an optional implementation, Figures 2 to 28 As shown, the adjacent ends of at least two connecting parts 121 are connected together so that the at least two connecting parts 121 form a cylindrical structure, and the connection between the two connecting parts 121 forms a connecting seam extending along the first direction D1, wherein the two ends of the connecting part 121 along the first direction D1 are respectively connected to the corresponding connecting flange 111 through a flange structure, and the adjacent ends of the two connecting parts 121 are connected through the flange structure. At the construction site, the connecting part 121 is connected to the integrated air duct 110 through the flange structure, and the adjacent connecting parts 121 are spliced ​​in sequence through the flange structure to form a cylindrical structure. The operator can preferentially connect the connecting part 121 located on the back of the spliced ​​air duct 100 with the integrated air duct 110 according to the operating position, which reduces the difficulty of splicing and assembly and makes the splicing and assembly operation more flexible.

[0105] For the specific structure of the connecting member 120, please refer to Figures 2 to 4 , Figures 9 to 15 , Figures 18 to 28 , which includes a first connecting component 1211 and a second connecting component 1212, wherein the first connecting component 1211 is arranged at the rear end of the second connecting component 1212, a split flange 130 is arranged between the connecting flange 111 and the first connecting component 1211, the connecting flange 111 and the split flange 130 are fixed by a first fastener 171, and the split flange 130 and the first connecting component 1211 are fixed by a second fastener 172. The operator can preferentially connect the first connecting component 1211 to the connecting flange 111 through the split flange 130 according to the operating position, which not only reduces the difficulty of splicing and assembly, but also enables the connection between the butt flange and the split flange 130, and the split flange 130 and the connecting component 121 to form a regular sealing gap, thereby ensuring the air tightness of the spliced ​​air duct 100.

[0106] Preferably, the connection seams between the butt flange and the split flange 130, and between the split flange 130 and the first connecting part 1211 are filled with flexible sealing materials, so that the connection between the butt flange and the split flange 130, and between the split flange 130 and the connecting part 121 has good air tightness.

[0107] like Figures 2 to 8 , Figures 12 to 17 , Figure 21 to Figure 24 and Fig.28 As shown, the second connecting component 1212 is respectively connected with a fixing flange 140 at both ends along the first direction D1, and the fixing flange 140 is fixed to the corresponding connecting flange 111 by a third fastener 173. Since the second connecting component 1212 is located at the front end of the first connecting component 1211, compared with the first connecting component 1211, the splicing and assembly difficulty of the second connecting component 1212 and the integrated air duct 110 is relatively low, and there is no need to connect to the connecting flange 111 through a split flange 130, which simplifies the splicing and assembly process. Preferably, the fixing flange 140 and the second connecting component 1212 are fixedly connected or integrally formed, which can effectively improve the assembly efficiency of the spliced ​​air duct 100.

[0108] Preferably, the connection seams between the fixing flanges 140 of adjacent connection components 121 are filled with a flexible sealing material to ensure the air tightness of the connection between the connection flange 111 and the fixing flange 140 .

[0109] like Figures 1 to 6 , Figures 12 to 15 , Figure 21 to Figure 24 and Fig.28As shown, the second connecting component 1212 is provided with a branch pipe interface 122, and the branch pipe is connected to the second connecting component 1212. The branch pipe is connected to the connecting component 120 through the branch pipe interface 122, so that the branch pipe is connected to the integrated air duct 110 through the connecting component 120, and the operator can fix the fixing flange 140 to the corresponding connecting flange 111 through the branch pipe interface 122.

[0110] For the specific structure of split flange 130, please refer to Figure 4 , Fig.15 and Fig.24 , which includes a docking wall 131 and a fitting wall 132, wherein the docking wall 131 and the connecting flange 111 are arranged opposite to each other along the first direction D1, and the docking wall 131 is fixed to the connecting flange 111 by a first fastener 171; the fitting wall 132 extends along the first direction D1, and the fitting wall 132 is arranged at the rear end of the first connecting component 1211, and the fitting wall 132 is fixed to the first connecting component 1211 by a second fastener 172, so that the split flange 130 is connected to the connecting flange 111 and the first connecting component 1211 in sequence.

[0111] like Figures 3 to 6 , Figure 8 , Fig.15 and Fig.24 As shown, the fixed flange 140 includes a fixed wall 141 arranged opposite to the connecting flange 111 along the first direction D1, and the fixed wall 141 is fixed to the connecting flange 111 by a third fastener 173. Preferably, the fixed wall 141 and the second connecting component 1212 are fixedly connected or integrally formed, which is easy to process and assemble, and can effectively reduce the difficulty of assembling the spliced ​​air duct 100.

[0112] like Figures 2 to 8 , Figures 12 to 17 , Figure 21 to Figure 24 and Fig.28 As shown, the two ends of the first connecting component 1211 are respectively provided with first side flanges 150 extending along the first direction D1, and the two ends of the second connecting component 1212 are respectively provided with second side flanges 160 extending along the first direction D1. The first side flange 150 and the second side flange 160 are fixed by a fourth fastener 174. Preferably, the first side flange 150 and the first connecting component 1211 are fixedly connected or integrally formed, and the second side flange 160 and the second connecting component 1212 are fixedly connected or integrally formed, which can effectively improve the assembly efficiency of the spliced ​​air duct 100.

[0113] Preferably, the connecting seam between the two connecting parts 121 is filled with a flexible sealing material, specifically, the connecting seam between the first surrounding flange 150 and the second surrounding flange 160 is filled with a flexible sealing material, so that the connection between the first connecting part 1211 and the second connecting part 1212 has good air tightness, thereby preventing air leakage in the connecting seam between the first surrounding flange 150 and the second surrounding flange 160.

[0114] like Figures 2 to 8 , Figures 12 to 17 , Figure 21 to Figure 24 and Fig.28 As shown, two ends of the second peripheral flange 160 along the first direction D1 are respectively connected integrally with the corresponding fixing flange 140 , which is easy to process and assemble.

[0115] Exemplarily, the cross section of the connecting member 120 is a polygon, and the number of sides of the polygon is greater than or equal to 4. Figures 2 to 6 As shown, at least one open end has an open slope that tilts inward from front to back, and the fixed wall 141 on the outside of the open slope has the same inclination direction as the open slope, so that the fixed flange 140 is sloped and arranged on the outside of the open slope, which is more convenient for assembly. In particular, when the fixed wall 141 with a flexible sealing material attached is sealed with the connecting flange 111, the fixed wall 141 has the same inclination direction as the open slope, which can prevent the fixed flange 140 and the connecting flange 111 from having excessive contact displacement and damaging the flexible sealing material.

[0116] like Figures 3 to 7 As shown, the first peripheral flange 150 is bent and extended backward at both ends along the first direction D1 to form abutment walls 180. The abutment walls 180 are arranged opposite to the corresponding connecting flange 111 along the first direction D1 and docked with the corresponding docking wall 131 to make the connection between the connecting component 120 and the integrated air duct 110 sealed and fitted.

[0117] like Figures 4 to 7 As shown, one of the two open ends of the connecting member 120 has an open plane perpendicular to the first direction D1, and the docking wall 131, the fixed wall 141 and the abutting wall 180 outside the open plane all extend perpendicular to the second direction D2, wherein the second direction D2 is perpendicular to the first direction D1 and parallel to the open plane, and the fixed flange 140 outside the open plane does not need to be sloped, and the fixed flange 140 is flatly arranged between the second connecting component 1212 and the connecting flange 111.

[0118] like Figures 2 to 7As shown, the abutment wall 180 on the outer side of the open inclined surface includes a first wall 181 and a second wall 182 arranged front and rear, the first wall 181 and the corresponding connecting flange 111 are arranged relatively to each other along the first direction D1, the second wall 182 is connected to the corresponding docking wall 131, and the angle between the first wall 181 and the reference plane perpendicular to the first direction D1 is α, wherein 20°≤α≤45°, which is conducive to the sealing connection between the docking wall 131 and the connecting flange 111.

[0119] Exemplarily, the cross section of the connecting member 120 is a quadrilateral, such as Figures 3 to 6 and Figure 8 As shown, the second connecting component 1212 and the fixed wall 141 are both U-shaped, and the two side walls of the fixed wall 141 outside the open inclined surface are inclined, and the angle between the two side walls of the fixed wall 141 and the reference plane perpendicular to the first direction D1 is β, wherein 20°≤β≤45°, which is conducive to the sealed connection between the fixed flange 140 and the connecting flange 111; preferably, 25°≤β≤30, in a limited installation space, to achieve rapid fixation of the fixed flange 140 and the connecting flange 111, and prevent the flexible sealing material attached to the fixed wall 141 from being deformed due to excessive displacement and affecting the sealing effect.

[0120] Exemplarily, the cross section of the connecting member 120 is circular or elliptical, such as Figures 13 to 17 As shown, the first connecting component 1211 and the second connecting component 1212 are both arc-shaped plates, the curvature of the second connecting component 1212 is greater than π, and at least one open end has an open slope inclined inward from front to back, and the docking wall 131 and the fixed wall 141 on the outside of the open slope have the same inclination direction as the open slope. Since the curvature of the second connecting component 1212 is greater than π, the assembly difficulty of the second connecting component 1212 and the integrated air duct 110 is relatively large, especially the fixed wall 141 attached with a flexible sealing material is sealed and fitted with the connecting flange 111, and the sloped setting of the fixed flange 140 can prevent the fixed flange 140 and the connecting flange 111 from having excessive contact displacement and damaging the flexible sealing material.

[0121] like Fig.16 and Fig.17 As shown, the angle between the docking wall 131 on the outside of the open bevel and the reference plane perpendicular to the first direction D1 is γ, and the angle between the fixed wall 141 on the outside of the open bevel and the reference plane is δ, wherein 20°≤γ=δ≤45°, which is conducive to the sealed connection between the fixed flange 140 and the connecting flange 111; preferably, 25°≤γ=δ≤30, so that the fixed flange 140 and the connecting flange 111 can be quickly fixed in a limited installation space, and the flexible sealing material attached to the fixed wall 141 can be prevented from being deformed due to excessive displacement and affecting the sealing effect.

[0122] like Figures 13 to 17 and Fig.21As shown, one of the two open ends of the connecting member 120 has an open inclined surface inclined inward from front to back, and the other has an open plane perpendicular to the first direction D1. The docking wall 131 and the fixed wall 141 on the outside of the open plane extend perpendicular to the second direction D2, wherein the second direction D2 is perpendicular to the first direction D1 and parallel to the open plane. The two open ends of the connecting member 120 form an open inclined surface and an open plane respectively. The operator can first fix the fixing flange 140 on the outside of the open plane with the corresponding connecting flange 111 to achieve a preliminary fixation of the connecting member 120 and one of the two integrated air ducts 110, and then further fix the fixing flange 140 on the outside of the open surface with the corresponding connecting flange 111, which can effectively improve the assembly efficiency of the spliced ​​air duct 100.

[0123] Exemplarily, the cross section of the connecting member 120 is circular or elliptical, and the first connecting member 1211 and the second connecting member 1212 are both arc-shaped plates and the arc is equal to π, such as Figure 22 to Figure 24 and Fig.28 As shown, the two open ends of the connecting member 120 have an open plane perpendicular to the first direction D1, and the docking wall 131 and the fixed wall 141 outside the open plane extend perpendicular to the second direction D2, wherein the second direction D2 is perpendicular to the first direction D1 and parallel to the open plane. Since the first connecting component 1211 and the second connecting component 1212 are both arc-shaped plates and the curvature is equal to π, the difficulty of splicing and assembling the second connecting component 1212 and the integrated air duct 110 is relatively low, so the fixing flange 140 does not need to be sloped, and the fixing flange 140 can be selected to be flatly set between the second connecting component 1212 and the connecting flange 111.

[0124] like Figures 9 to 12 , Figures 18 to 21 and Figure 25 to Figure 28 As shown, the spliced ​​air duct 100 is manufactured by the following steps:

After the connecting component 121 rebounds and resets, the first end 123 and the second end 124 are connected together by the first fastener 171.

[0134] like Figure 29 to Figure 32 As shown, the connecting component 121 is provided with a branch pipe interface 122, the branch pipe is connected to the second connecting component 1212, the branch pipe is connected to the connecting component 120 through the branch pipe interface 122, so that the branch pipe is connected to the integrated air duct 110 through the connecting component 120, and the operator can fix the first end 123 and the second end 124 through the branch pipe interface 122.

[0135] Preferably, the connecting seam between the two ends is filled with a flexible sealing material, specifically, the connecting seam between the first end 123 and the second end 124 is filled with a flexible sealing material, so that the connection between the first end 123 and the second end 124 has good sealing properties, avoiding the risk of air leakage in the spliced ​​air duct 100.

[0136] like Fig.29 and Fig.31 As shown, the first end 123 and the second end 124 are respectively provided with connecting holes 126, and the first fastener 171 passes through the connecting holes 126 provided at the first end 123 and the second end 124 in sequence. The operator fixes the first end 123 and the second end 124 through the branch pipe interface 122 so that the first fastener 171 fastens the first end 123 and the second end 124.

[0137] Exemplarily, the cross section of the connecting member 120 is a polygon, and the number of sides of the polygon is greater than or equal to 4. Fig.29 and Fig.30 As shown, one of the two end portions of the connecting component 121 is bent and extended toward the inside of the cylindrical structure to form a butt flange 125, and the other is located on the outside of the butt flange 125 and is fixed to the butt flange 125 by a first fastener 171.
