Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a roof drainage system for clean rooms. Background Technology
[0002] When constructing industrial plants with cleanroom requirements, cleanroom roof panels need to be spliced together to form the roof structure of the cleanroom. The connection nodes between adjacent roof panels are composed of arched keels and T-shaped profiles or T-shaped hanging beams at the ends of the roof panels.
[0003] In the aforementioned technical solutions, with prolonged use, the high humidity in the cleanroom, or the moisture and condensation on the ceiling, can cause the hand-made panel ceiling to become soaked, leading to problems such as panel detachment. Additionally, during pipeline testing after the cleanroom is constructed, localized water may be present, which can easily cause water leaks at connection points. Utility Model Content
[0004] This invention provides a ceiling drainage system for cleanrooms, which can solve at least one of the above-mentioned technical problems.
[0005] To address the aforementioned technical problems, one or more embodiments of this utility model provide a ceiling drainage system for cleanrooms, comprising multiple ceiling panels sequentially spliced along their long and short sides, with joints formed between adjacent panels. The joint extending along the short side of the ceiling panel is a first joint, and the joint extending along the long side is a second joint. A keel is fixed to both the long and short sides of the ceiling panel. A drainage beam is provided within the first joint, and a drainage board assembly is provided within the second joint. The end face of the keel away from the ceiling panel has an upper protrusion and a lower protrusion extending away from the ceiling panel, with the upper protrusion extending less than the lower protrusion, forming a slot between the upper and lower protrusions. A hollow groove is formed between two adjacent upper protrusions, and the slot and hollow groove combine to form a stepped groove. Both the drainage beam and the drainage board assembly include a connecting seat for connecting two slots, the connecting seat having an open upper end facing the drainage cavity of the hollow groove. The drainage beam has a suspension portion connected to the connecting seat and extending upwards outwards into the hollow groove. The drainage board assembly has a sealing part that connects to the connector and extends upward to seal the empty groove.
[0006] The beneficial effects of one or more of the above technical solutions are as follows:
[0007] Compared to traditional bow-shaped keel, the keel in this design includes upper and lower protrusions, forming a slot between them. The length of the upper protrusion is shorter than that of the lower protrusion. This design facilitates the creation of a larger slot between the keels of two adjacent ceiling slabs. Compared to traditional U-shaped profiles or U-shaped suspension beams, the profiles used for connection in this design have an open drainage cavity at the top on the connecting seat, which faces the slot.
[0008] In this solution, regardless of whether it is the joint on the short or long side of the roof slab, the condensed water vapor or water leaking from the pipes can be collected in the drainage chamber using the hollow groove. Then, the excess water can be drained along the extension direction of the joint using the drainage chamber, thus avoiding damage to the roof slab caused by water immersion due to prolonged accumulation of water vapor.

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0016] like Figures 1-5As shown, one or more embodiments of this utility model provide a ceiling drainage system for cleanrooms, including multiple ceiling panels 1 sequentially spliced along their long and short sides, with joints 7 formed between adjacent ceiling panels 1. The joint 7 extending along the short side of the ceiling panel 1 is a first joint, and the joint 7 extending along the long side is a second joint. A keel 2 is fixed to both the long and short sides of the ceiling panel 1. A drainage hanger 4 is provided within the first joint, and a drainage board assembly is provided within the second joint. The end face of the keel 2 facing away from the ceiling panel 1 has an upper protrusion 23 and a lower protrusion 21 extending in a direction away from the ceiling panel 1, with the upper protrusion 23 extending less than the lower protrusion 21, and a slot 72 is formed between the upper protrusion 23 and the lower protrusion 21. A hollow groove 71 is formed between two adjacent upper protrusions 23, and the slot 72 and the hollow groove 71 combine to form a stepped groove. Both the drainage hanger beam and the drainage board assembly include a connecting seat 6 for connecting the two slots 72. The connecting seat 6 has an open upper end and faces the drainage cavity 9 of the empty slot 71. The drainage hanger beam has a suspension portion 4 that connects to the connecting seat 6 and extends upward out of the empty slot 71. The drainage board assembly has a sealing portion 5 that connects to the connecting seat 6, extends upward, and seals the empty slot 71.
[0017] The drainage system in this embodiment has a first direction, a second direction, and a third direction that are perpendicular to each other. The first direction is parallel to the long side extension direction of the top plate 1, the second direction is parallel to the short side extension direction of the top plate 1, and the third direction is a vertical direction (and parallel to the thickness direction of the top plate 1).
[0018] As can be seen, the only difference between the first joint and the second joint is the length of their extensions. The keel 2 structure of the first joint and the second joint, as well as the slot 72 and empty slot 71 formed by the keel 2, are the same.
[0019] As a specific structural form, the top plate 1 here includes a core material 11 and panels 12 attached to two sides of the core material 11. The panels 12 are fixed to the core material 11 by adhesive. More specifically, the end of the keel 2 facing away from the slot 72 abuts against the end face of the core material 11, and the edge of the panel 12 is bent vertically to form a folded edge. The keel 2 is confined between the folded edge and the core material 11.
[0020] Specifically, the width formed by the two slots 72 is greater than the width of the empty slot 71, thus forming the aforementioned stepped slot.
[0021] In this embodiment, the suspension part 4 includes a vertical plate 43, a horizontal plate 42 and a top seat 41 connected sequentially from bottom to top. The lower end of the vertical plate 43 is connected to the bottom surface of the drainage cavity 9 in the connecting seat 6. The horizontal plate 42 spans the joint 1 of the two top plates and is attached to and fixed to the upper surface of the top plate 1.
[0022] Specifically, there is an upwardly protruding structural reinforcement between the vertical plate 43 and the bottom surface of the drainage cavity 9 in the connecting seat 6, so as to increase the connection strength between the suspension part 4 of the hanging beam and the connecting seat 6.
[0023] In this embodiment, the sealing part 5 includes a vertical plate 52 and an inverted U-shaped plate 51 connected sequentially from bottom to top. The lower end of the vertical plate 52 is fixed to the connecting seat 6, and the two vertical sides of the inverted U-shaped plate 51 abut against the adjacent upper protrusion 23 respectively.
[0024] Specifically, the upper end of the vertical plate 52 is connected to the center of the inverted U-shaped plate 51 along the first joint width direction (i.e., the second direction).
[0025] In this embodiment, the keel 2 also includes a stop portion 22 integrally formed with the upper protrusion 23 and the lower protrusion 21. The stop portion 22 abuts against the core material 11 of the top plate 1. The cross-sectional profiles of the stop portion 22, the upper protrusion 23 and the lower protrusion 21 in the direction perpendicular to the extension of the joint 7 are respectively square.
[0026] Specifically, the stop part 22, the upper protrusion 23 and the lower protrusion 21 here are all square structures, each with a square cavity, in order to achieve weight reduction.
[0027] In this embodiment, the upper protrusion 23 of the keel 2 is fixed to the panel 12 of the top plate 1 by screws 3.
[0028] Specifically, the screw 3 passes through the upper and lower sidewalls of the panel 12 and the upper protrusion 23 respectively, so as to increase the connection strength between the keel 2 at the end of the top plate 1 and the panel 12.
[0029] In this embodiment, the upper protrusion 23 on the short side of the top plate 1, the panel 12, and the adjacent horizontal plate are fixed by screws 3.
[0030] Specifically, the two ends of the horizontal side are fixed to the two top plates 1 by screws 3, which facilitates the stable connection between the drainage beam and the two adjacent keels 2.
[0031] In this embodiment, a gap is formed between the lower protrusions 21 of the two top plates 1, and a partition strip 8 is provided in the gap. The partition strip 8 extends upward to be fixed to the connecting seat 6, and the gap is filled with sealant.
[0032] Specifically, the separator 8 here adopts an inverted T-shaped structure. The lower part of the separator 8 has a horizontal edge, and the two ends of the horizontal edge abut against the end face of the lower protrusion 21 in the keel 2.
[0033] In this embodiment, the connecting seat 6 includes two side seats 62, the lower ends of the two side seats 62 are connected by a base 63, and the upper end of the side seat 62 has a flat plate 61 extending toward the joint 7. The length of the flat plate 61 and the flat seat along the direction perpendicular to the joint 7 is equal to the length of the upper protrusion 23.
[0034] Specifically, the side seat 62 and the base 63 here each have a square cavity in the center, and the side seat 62 and the base 63 also adopt an integral molding structure.
[0035] Working principle: When using this device, multiple top plates 1 are connected along the short side and the long side respectively. The connection node at the short side of the top plate 1 is formed by the combination of two keels 2 and the drainage hanging beam, and the connection node at the long side of the top plate 1 is formed by the connection of two keels 2 and the drainage board assembly.
[0036] When water vapor accumulates at the connection point of the top plate 1 or water leaks from the water supply pipeline, the water is accumulated in the drain cavity 9 of the connecting seat 6 and then flows out from the drain cavity 9 along the direction of the joint 7, so as to avoid water damage to the top plate 1 caused by water vapor accumulation.
[0037] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
[0038] Any aspects of this utility model not described in detail are known to those skilled in the art.
