1. Material selection and technical specifications for medical steel doors
A. Material selection for door frames and door leaves of medical steel doors ：
1) Professional medical steel door frames are made of Baosteel or Shougang high-quality hot-melt galvanized steel sheets (SGCC) with a thickness of ≥1.5mm to ensure the overall stability of the door frame; the thickness of the door frame should be customized according to the thickness of the wall to create a door cover effect, vertical and horizontal frames Frames are spliced vertically, no welding or touch-up paint;
2) The door frame needs to be equipped with a sealing strip. The sealing strip must be made of high-quality rubber material, glue-free physical inlay, environmentally friendly, silent, guaranteed sealing effect and easy to replace;
B. Technical requirements for medical steel door leaves;
1) Surface material: Use high-quality hot-melt galvanized steel plate (SGCC), steel plate thickness ≥0.8mm;
2) Surface treatment: Use high-voltage electrostatic spraying, monochrome effect, or PVC wood grain peritoneum; door leaves are prohibited from using cheap raw materials such as cheap color steel plates.
3) Surface spraying treatment of medical steel door leaves: high-voltage electrostatic spraying is required, with good acid resistance and solvent resistance; the coating uses high-quality environmentally friendly powder, such as Tiger Or Aksu brand; it is required to be dust-proof, anti-bacteria, smooth spray surface, no cracks, blistering, spray thickness ≥ 40UM.
4) The thickness of the professional medical steel door leaf ranges from 40mm to 50mm. There are no solder joints on the surface of the door leaf, and there are no solder joints, rivets, and front and back door panels around the door leaf. Using self-biting technology, it is strong, flat and beautiful and easy to keep clean.
5) The support structure uses a hot-dip galvanized steel plate inner frame group with a thickness of ≥1.6mm to ensure the strength and non-deformation of the professional medical steel door leaves.
6) Filling material: made of high qualityFireproof honeycomb core paper is filled and fully connected with the inner surface of the steel plate to ensure the impact resistance of the door panel.
7) 5mm or 6mm tempered glass can be used for hospital-specific steel door door windows.
2. Technical indicators of professional medical steel door ward doors:
1) It has good sound insulation, airtightness and heat preservation Effective, silent design ensures quiet opening and closing of the door.
2) The sound insulation effect is level V, 35dB>Rw≥25dB
3) Professional medical steel ward door : The door leaf is made of 0.8mm high-quality steel plate, filled with green environmentally friendly non-combustible materials; the door frame is made of 1.5mm high-quality steel plate, with sealing strips embedded inside; the surface is electrostatic powder sprayed or PVC coated steel plate.
4) The single door adopts the cover-less type, and the double-door and bi-fold doors adopt the original cover with its own buckle to ensure that the door is overall smooth and beautiful.
5) The interior is filled with high-strength honeycomb cardboard and is fully bonded to the steel plate for strong impact resistance. The lower part of the bathroom door is equipped with breathable blinds.
6) If the wall thickness at the construction site is greater than or equal to 200MM, it is required to provide all-inclusive wall door frames (integrated door frames) to meet the needs of various wall thicknesses on site.
7) The internal lining of the door frame needs to be thickened (taking into account the installation of its magnetic lock and supporting hardware, etc., the strength of the product must be ensured).
8) Professional medical steel door windows and blinds:
① Equipped with a glass door with a window, the window is 5mm For single-layer tempered glass windows, the window beading shall be aluminum alloy beading, and the window beading shall not be 3.5mm higher than the plane of the door leaf; for door bodies with shutters, the shutters shall be made of high-strength steel or aluminum alloy shutters.
② The aluminum alloy glass bead is anodized, resistant to pickling, non-corrosive, has good durability, soft color, no screws and no welds on the surface; it must be sprayed with the same color as the door panel.
③45° angle, no screw holes on the surface, easy to clean
9) Medical steel door hardware accessories :
① Select the specific type of hardware accessories according to the location and function of the door, clearly indicate the selected brand model to ensure the durability of the door; manufacturer\’s authorization letter or domestic agent authorization letter; hinge , locks and other hardware accessories must provide national type inspectionreport.
② Hardware, accessories, and fasteners should meet functional requirements, be installed in correct, complete, and firm locations, have sufficient strength, open and close flexibly, and be noise-free.
Hinges: Use high-strength and high-quality stainless steel hinges, with at least 2 pairs of hinges for each door panel. Fixed with high-quality steel screws; the hinge has undergone 24 hours of non-stop fatigue testing and has been used more than 300,000 times.
3. Professional medical steel door installation process:
①The door frame and door leaf are installed separately on site to facilitate transportation Simple and convenient for finished product protection. The door frame adopts 45° angle or 90° angle. High installation accuracy is required. The allowable deviation of the width of the door frame is ±1mm, the verticality of the two frames is ≤2mm, the diagonal difference of the door frame is ≤3mm, the elevation of the door frame reference line is <2mm, the installation position of the door frame in the opening is <5mm, and the door leaf is in Installation is done after the cement mortar has completely hardened. When installing the door frame sealing strip, there should be no joint in the middle, and the joints of the sealing strips on the three sides should be at a 90° angle. High precision is required when assembling the door leaf and door frame to ensure the sound insulation performance of the door body.
② The installation of professional medical steel door hinges requires opening holes in the door frame and door leaf, and adding lining boards for installation.
③The door frame, door type and installation method of professional medical steel doors must be in full compliance with the process requirements of the design drawings.
④ Responsible for the grouting work of the door frame edge seams to ensure that it is firmly connected to the structure and does not deform.
4. Precautions for professional medical steel doors:
1. Transportation of medical steel doors:
The transport vehicles transporting factory-inspected medical steel doors to the construction site should have rainproof measures, a flat and clean chassis, and sufficient length and width. The metal door frames and door leaves are loaded separately, the door frames are placed neatly and horizontally, and the door leaves are laid flat. Door loading requirements: The binding must be firm and reliable, there must be no looseness, there should be a cushion, and no direct contact with the surface of the door frame and door leaf to avoid scratching the surface coating during long-distance transportation. When loading and unloading door frames and door leaves, handle them with care and do not pry, throw or drop them. When transporting door frames and door leaves, attention should be paid to: the loading quantity and height are determined according to the vehicle model and the type and size of the door frame and door leaves.
2. Storage of medical steel doors
When transporting metal doors to the construction site, attention should be paid to the door frames and door leaves. protection. Door frames and door leaves should be placed in a dry and clean place with a flat floor, away from the sun and rain, and must not come into contact with corrosive substances. Door frames and door leaves should not be in direct contact with the ground, should be padded with sleepers and placed upright. The door frame of a three-frame door (without threshold) should be placed upside down, that is, the upper frame faces downwards. The door frame and door leaves of four-frame doors should be placed upright. The stacking angle shall not be less than 70°, the number stacked in a single row shall not exceed 50, and measures shall be taken to prevent tipping.
