Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to a corner profile and a clean plate assembly for a clean room. Background Art

[0002] A clean room is a storage or working space that needs to control parameters such as air cleanliness, temperature, humidity, pressure, and noise, and has good airtightness. Clean panels are generally used in the construction process of a clean room. Adjacent clean panels are generally at different angles such as 180 and 90 degrees. Adjacent clean panels are connected and bonded using Chinese-shaped connectors or right-angle connectors to enhance the stability of the connection between adjacent clean panels.

[0003] In the related technical solution, two clean panels with an angle of 135 degrees need to be connected. At this time, the Chinese-shaped connector or the right-angle connector is not suitable for this scenario. The inventor tried to make the corresponding corner profile according to the shape of the gap between the two clean panels with an angle of 135, but it is easy to cause the panel to be damaged by thermal expansion and contraction due to the stop of the connector. Utility Model Content

[0004] The utility model provides a corner profile and a clean board component for a clean room, which can solve at least one of the above technical problems.

[0005] In order to solve the above technical problems, one or more embodiments of the utility model provide a corner profile for a clean room, which is used to connect two clean panels with an angle of 135 degrees, including two acute-angled panels with an angle of 45 degrees and two obtuse-angled panels with an angle of 135 degrees, the ends of the two acute-angled panels that are close to each other are connected by a first curved panel, the ends of the two acute-angled panels that are far away from each other are connected to the obtuse-angled panels by a second curved panel, and the ends of the two obtuse-angled panels that are far away from the acute-angled panels are connected to each other; the two acute-angled panels, the two obtuse-angled panels and the first curved panel and the two second curved panels are connected in sequence to form a closed profile; the outer side surface of the acute-angled panel is provided with a connector that is plugged into the clean panel to achieve positioning; the length L1 of the cross-section of the acute-angled panel is greater than the thickness of the core panel of the clean panel to be connected, and the length L1 is less than the thickness of the clean panel.

[0006] One or more embodiments of the utility model further provide a clean panel assembly, including the above-mentioned corner profile for clean room, and at least two clean panels, the clean panel including a core panel and two side surfaces attached to the core panel, the side surfaces of the clean panel are embedded with keels, and the keels are provided with slots; the first curved panel and the second curved panel are filled with adhesive between the adjacent clean panels. The beneficial effects of one or more of the above technical solutions are:

[0007] In this solution, the angle between the two acute-angle plates is 45 degrees, and the angle between the two obtuse-angle plates is 135 degrees. The shape formed by the combination of the acute-angle plates and the obtuse-angle plates is convenient for filling the gap between the interfaces of the two clean plates with an angle of 135 degrees, so that the two acute-angle plates can limit the adjacent clean plates by the insertion of the connector and the outer side stop. The two obtuse-angle plates can achieve approximate coverage of the outer side panels of the adjacent clean plates.

[0008] In this solution, two adjacent acute-angle plates are connected by a first curved plate, and adjacent acute-angle plates and obtuse-angle plates are connected by a second curved plate. In addition, the length L1 of the cross section of the acute-angle plate is greater than the thickness of the core plate of the clean plate to be connected, and the length L1 is less than the thickness of the clean plate. This arrangement prevents the acute-angle plate from completely abutting against the panel of the clean plate, which is beneficial for reserving some space for the thermal expansion and contraction deformation of the panel when the abutment limit panel is applied. In addition, this arrangement also facilitates reserving more glue space at the first curved plate and the second curved plate, which facilitates increasing the stability of the bonding between the corner profile and the clean plate; and when there is more adhesive, it is convenient to use the adhesive to absorb the thermal expansion and contraction deformation of the panel, reducing the probability of a gap between the corner profile and the panel.

[0013] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0014] like Figure 1-Figure 2As shown, one or more embodiments of the utility model provide a corner profile for a clean room, which is used to connect two clean panels 8 with an angle of 135 degrees, including two acute-angled panels 1 with an angle of 45 degrees and two obtuse-angled panels 3 with an angle of 135 degrees, the ends of the two acute-angled panels 1 that are close to each other are connected by a first curved panel 6, the ends of the two acute-angled panels 1 that are away from each other are connected to the obtuse-angled panel 3 by a second curved panel 4, and the ends of the two obtuse-angled panels 3 that are away from the acute-angled panels 1 are connected to each other; the two acute-angled panels 1, the two obtuse-angled panels 3 and the first curved panel 6 and the two second curved panels 4 are connected in sequence to form a closed profile; the outer side surface of the acute-angled panel 1 is provided with a connector that is plugged into the clean panel 8 to achieve positioning; the length L1 of the cross-section of the acute-angled panel 1 is greater than the thickness of the core panel 802 of the clean panel 8 to be connected, and the length L1 is less than the thickness of the clean panel 8.

[0015] See also Figure 1 At this time, the acute-angled plate 1 is respectively a first plate body 101 and a second plate body 102, and the obtuse-angled plate 3 is respectively a third plate body 301 and a fourth plate body 302. It should be noted that the acute-angled plate 1 and the obtuse-angled plate 3 are both flat plates.

[0016] Specifically, the clean board 8 here includes a core board 802, and the two side surfaces of the core board 802 perpendicular to its thickness direction are respectively attached with the panel 801, and the core board 802 and the panel 801 are bonded into a sandwich structure by an adhesive. In order to achieve the connection between adjacent clean boards 8 and increase the structural strength of the clean board 8, the clean board 8 is embedded with a keel 803 at least at the side surface where the splicing position is required. In some technical solutions, the keels 803 are respectively embedded at the four side surfaces of the square clean board 8, and in other technical solutions, the square clean board 8 is embedded with the keel 803 only at one pair of two side surfaces arranged oppositely.

[0017] The aforementioned corner profile is used to connect two clean plates 8 with an included angle of 135 degrees, which means that the included angle between two adjacent side surfaces of adjacent clean plates 8 is 135 degrees.

[0018] In this embodiment, the acute angle plate 1, the obtuse angle plate 3, the first curved plate 6 and the second curved plate 4 are integrally formed. Preferably, the material of the corner profile is aluminum; in other embodiments, other materials may also be used, which can be set by those skilled in the art.

[0019] In this embodiment, the first plate body 101, the second plate body 102, the first curved plate 6, and the second curved plate 4 enclose the inner cavity 9 of the corner profile, and the first curved plate 6 and the second curved plate 4 are concave toward the inner cavity 9 of the corner profile, that is, the outer curved surfaces of the first curved plate 6 and the second curved plate 4 face the inner cavity 9 of the corner profile. This arrangement makes it easy to use the first curved plate 6 and the second curved plate 4 to form a receiving groove for receiving the adhesive.

[0020] Specifically, the first curved plate 6 and the two acute-angle plates 1 enclose a first receiving groove 7, and the adjacent acute-angle plates 1 and obtuse-angle plates 3 are enclosed by the second curved plate 4 to form a second receiving groove 5. The first receiving groove 7 and the second receiving groove 5 are used to contain adhesive.

[0021] In this embodiment, the connector is a limit plate 2 used in pairs, the two limit plates 2 used in pairs are perpendicular to the acute-angle plates 1 on which they are located, and the two limit plates 2 used in pairs are parallel to each other, and the extension direction of the limit plates 2 is the same as the extension direction of the acute-angle plates 1.

[0022] Specifically, the extension length of the limiting plate 2 along the direction perpendicular to the acute-angle plate 1 is not greater than the depth of the groove on the keel 803 to be plugged in.

[0023] In this embodiment, a stop space is defined between two limit plates 2 used in pairs, and a bending portion bent toward the center of the stop space is provided at the end of the limit plate 2 away from the acute angle plate 1. This arrangement makes it easy to use the bending portion to guide and insert the connector into the slot 804.

[0024] In this embodiment, the distance between the two limiting plates 2 used in pairs and away from the side is equal to the thickness of the slot 804 at the keel 803 in the clean plate 8 to be connected.

[0025] One or more embodiments of the present invention further provide a clean panel 8 assembly, including the above-mentioned corner profile for clean room, and at least two clean panels 8, the clean panel 8 including a core panel 802 and two side surfaces attached to the core panel 802, a keel 803 is embedded in the side surface of the clean panel 8, and a slot 804 is provided on the keel 803; an adhesive is filled between the first curved panel 6 and the second curved panel 4 and the adjacent clean panels 8.

[0026] Specifically, the keel 803 here is a bow-shaped keel. In some other structural settings, the keel can also adopt other shapes.

[0027] Working principle: When in use, firstly, plug the connector at one of the acute angle plates 1 (such as the first plate body 101 shown in the figure) of the corner profile into the corresponding slot 804 of the keel 803. Then move another clean plate 8 to a position close to the corner profile, and plug the connector of another acute angle plate 1 (such as the second plate body 102 shown in the figure) into the corresponding slot 804 of the keel 803.

[0028] After the connection is completed, the first plate body 101 and the second plate body 102 respectively stop at the keel 803 and a small part of the panel 801 on the side of the clean plate 8, and then fill the first receiving groove 7 and the second receiving groove 5 with adhesive, use the adhesive to seal the joints, and achieve a stable connection between the corner profile and the clean plate 8.

[0029] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0030] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
