[0046] See also Figures 1 to 7 An embodiment of the utility model provides a steel door for a clean room, the steel door comprising a door frame 100 and a door leaf 200 .
[0047] The door frame 100 is installed on the wall 1 .
[0048] The door leaf 200 is hinged to the door frame 100 so that the door leaf 200 can rotate relative to the door frame 100 and has a closed state and an open state. A honeycomb filler 210 is provided inside the door leaf 200 to improve the sound insulation performance of the door leaf 200.
[0049] The door frame 100 includes a first frame column 110, a third frame column 130, and a fourth frame column 140. The first frame column 110 and the third frame column 130 are parallel to each other, and both ends of the fourth frame column 140 are respectively connected to the first frame column 110 and the second frame column 120. Of course, in some other embodiments, the door frame 100 also includes a second frame column 120, and the first frame column 110, the second frame column 120, the third frame column 130, and the fourth frame column 140 are connected to each other end to end, and the second frame column 120 is buried in the floor to improve the stability of the door frame.
[0050] Each frame column includes a first frame body 150 and a second frame body 160 connected to each other. The first frame body 150 is fixed on the wall body 1. A sealant 300 is arranged between the first frame body 150 and the wall body 1 to improve the sealing between the first frame body 150 and the wall body 1. The sealant 300 can be glass glue.
[0051] The second frame 160 includes a seal 161 , which is disposed opposite to the door leaf 200 . When the door leaf 200 is in a closed state, the door leaf 200 may be pressed against the seal 161 , thereby improving the sealing between the door leaf 200 and the second frame 160 .
[0052] That is to say, the sealing between the first frame column 110, the second frame column 120, the third frame column 130 and the fourth frame column 140 and the wall 1 can be improved; the sealing between the first frame column 110, the second frame column 120, the third frame column 130 and the fourth frame column 140 and the door leaf 200 can also be improved.
[0053] It can be understood that the steel door for a clean room provided in the embodiment of the utility model improves the sound insulation performance of the door by arranging a honeycomb filler 210 in the door leaf 200; each frame column of the door frame 100 is divided into a first frame body 150 and a second frame body 160 which are connected to each other, and a sealant 300 is arranged between the first frame body 150 and the wall 1, and a seal 161 which can be tightly pressed against the door leaf 200 is arranged between the second frame body 160 and the door leaf 200, so as to improve the sealing between each frame column and the wall 1, and improve the sealing between each frame column and the door leaf 200; thereby improving the sound insulation and sealing performance of the door, avoiding affecting the internal environment of the clean room, and improving the overall quality of the clean room.
[0054] Specifically, combined Figure 3 and Figure 4In some embodiments of the present invention, the seal 161 includes a first seal 1611 and a second seal 1612 .
[0055] The door leaf 200 includes a door leaf back 220 and a door leaf side 230. The first seal 1611 is arranged opposite to the door leaf back 220, and the second seal 1612 is arranged opposite to the door leaf side 230. When the door leaf 200 is in a closed state, the first seal 1611 is tightly sealed against the door leaf back 220, and the second seal 1612 is tightly sealed against the door leaf side 230. The first seal 1611 and the second seal 1612 are respectively tightly sealed against different surfaces of the door leaf 200, which can further improve the sealing between the door leaf 200 and the door frame 100 and reduce the risk of sealing failure. The first seal 1611 can be an airtight rubber strip, and the second seal 1612 can be a rubber plug.
[0056] Furthermore, in order to weaken the vibration of sound and improve the sound insulation performance between the door frame 100 and the wall 1, in some embodiments of the utility model, each frame column also includes a plate 170, the first frame 150 is provided with a accommodating cavity 151, and the plate 170 is arranged in the accommodating cavity 151. The plate 170 can be a wooden board or a gypsum board.
[0057] In order to facilitate the installation of each frame column on the wall 1, in some embodiments of the utility model, the frame column also includes a connecting piece 180, which is inserted into the second frame 160 and the plate 170 in sequence and connected to the wall 1, so that the first frame 150 and the second frame 160 can be fixed on the wall 1, and the connecting piece 180 can be a self-tapping screw.
[0058] In addition, the frame column also includes a U-shaped groove edging member 190, the first side of the U-shaped groove edging member 190 is clamped on the wall 1, and the second side of the U-shaped groove edging member 190 is abutted against the plate 170. At this time, the connecting member 180 passes through the plate 170 and the U-shaped groove edging member 190, so that the first frame 150 can be more firmly fixed on the wall 1.
[0059] Combination Figure 4 In some embodiments of the utility model, the first frame 150 is provided with a reinforcing rib 152, a structural adhesive layer 153 is provided between the reinforcing rib 152 and the wall 1, and a structural adhesive layer 153 is also provided between the accommodating cavity 151 and the wall 1. The structural adhesive layer 153 can improve the sealing between the first frame 150 and the wall 1, and can also reduce the vibration of sound to improve its sound insulation performance.
[0060] In some embodiments of the present invention, the door leaf 200 can be made of an electrolytic plate, for example, by electroplating a steel plate to form a uniform, dense, well-bonded metal or alloy deposition layer to further prevent corrosion of the door leaf 200 and increase its lifespan.
[0061] Furthermore, in some embodiments of the present invention, the door also includes a sweeping rubber 400 and an observation window 500 .
[0062] The observation window 500 is arranged on the door leaf 200 so that the staff can understand the situation in the clean room at any time and make work arrangements in time.
[0063] The sweeping rubber 400 is arranged on the bottom side of the door leaf 200, and the sweeping rubber 400 abuts against the floor of the clean room to avoid a gap between the bottom side of the door leaf 200 and the floor, which can effectively improve the sound insulation and sealing performance.
[0064] Combination Figure 6 In some embodiments of the present invention, the door leaf 200 includes a first door leaf 240 and a second door leaf 250 .
[0065] The first door leaf 240 is hinged to the first frame column 110 , and the second door leaf 250 is hinged to the third frame column 130 .
[0066] The first door leaf 240 is provided with a first rubber strip 241, and the second door leaf 250 is provided with a second rubber strip 251. The first rubber strip 241 and the second rubber strip 251 are arranged opposite to each other, so that when the door leaf 200 is in a closed state, the first rubber strip 241 and the second rubber strip 251 are pressed against each other and sealed. The door leaf 200 is provided with a first door leaf 240 and a second door leaf 250, which can meet the needs of different clean rooms and facilitate the entry and exit of articles of different specifications or sizes in and out of the clean room. At the same time, the first rubber strip 241 is provided on the first door leaf 240 and the second rubber strip 251 is provided on the second door leaf 250, so as to improve its sealing and sound insulation performance.
