One, what are the acceptance specifications for non-standard fire doors?
1. Examine and verify the product certificate and on-site acceptance records. Verify that the fire door frame is securely installed and that its position and opening direction comply with the design requirements. Verify that the number, position, and installation/connection method of embedded steel components comply with the design requirements.
2. Check basic items: - Qualified fire doors: Close tightly, operate smoothly, no deformation or deflection, good sealing, and automatic closing is sensitive. - Excellent fire doors: Close tightly, operate smoothly, no obstruction or rebound, no deformation or deflection, good sealing, and automatic closing is sensitive. - Non-standard fire doors: Automatic closing is sensitive.
3. Inspect non-standard fire door accessories:- Qualified fire doors: Accessories are complete, securely installed, and positioned correctly, with smooth operation.- Excellent fire doors: Accessories are complete, securely installed, and positioned correctly, with a neat appearance, smooth operation, and suitability.
4、Inspect the sealing quality of gaps between fire-resistant frames and walls.。Certified fire door：Fully filled、Fill material meets design specifications.。High-quality fire door：Dense and full、Smooth surface、Fill material meets design specifications.。
5. Inspect the quality of non-standard fire doors.Qualified fire doors: The surface is smooth, clean, and free of pinholes, pits, and rust; the surface coating color is uniform.Excellent fire doors: The surface is smooth, clean, and free of scratches, pinholes, pits, and rust; the surface coating color is uniform and the coating film is smooth, beautiful, and aesthetically pleasing.
II. Detailed Specifications for the Installation and Acceptance of Fire Doors
1、Fire-resistant door construction acceptance specifications
① The installation of fire doors shall comply with the requirements specified in construction drawings, design specifications, and design change notices.
② The installation process of fire doors should undergo quality control. Quality checks should be performed after each stage of work, and the construction unit should be responsible for conducting these checks, with the supervision unit overseeing the process. Concealed works should be inspected by relevant parties before being concealed, as notified by the construction unit.
③ Inspection of the installation process for non-standard fire doors should be documented according to the required format, including the installation process inspection record and the acceptance record for concealed works. After passing the inspection, the installation should be reviewed and approved by the site supervisor before proceeding with the commissioning.
④ Except for special circumstances, fire doors should open in the direction of the exit. After the fire door is closed, it should be manually opened from either side.
⑤ Self-closing devices and sequential operators should be installed on automatic fire doors. Double and multi-leaf fire doors should be equipped with sequential operators.
⑥ For frequently opened fire doors, control, signaling, and manual override devices that automatically close the door leaf in case of fire should be installed, and these devices must comply with the product specifications.
⑦The installation of the electric control device for fire doors should comply with the design requirements and product specifications.
⑧ Fire-resistant fasteners should be installed on the door leaf of a double-door or multi-door where the two leaves are fixed together.
⑨ The fire-resistant seals installed at the joints between the fire door frame and the door leaf, and between the door leaf and the door leaf, should be firm and intact.
⑩Fire-resistant doors installed near expansion joints should be located on the side with more floors, and the door leaf should not cross the expansion joint when opened.
⑪The steel fire-resistant door frame should be filled with cement mortar. The door frame should be securely connected to the wall using embedded steel components or expansion bolts, with a spacing between the connection points not exceeding 600mm.
⑫The overlap dimension between the fire door leaf and the door frame should not be less than 12mm.
⑬The operating clearance between the fire door leaf and the door frame should comply with the following requirements:
The clearance between the door leaf and the door frame, particularly at the hinge side, should not exceed the dimensional tolerance specified in the design drawings. The clearance between the door leaf and the door frame, particularly at the locking side, should not exceed the dimensional tolerance specified in the design drawings. The clearance between the door leaf and the upper frame should not exceed 3mm. The gap between door leaves or multiple door leaves should not exceed 3mm. The clearance between the door leaf and the lower frame or the floor should not exceed 9mm. The gaps between the door leaf and the door frame, at the hinge side, the locking side, and the upper frame, should not exceed 3mm.
⑭ After installing the fire door, the door leaf should open and close smoothly, without any rebounding, warping, jamming, or tight closure.
⑮Under normal circumstances, the opening force of fire doors should not exceed 80N.
2、How to inspect fire doors
① After the fire door is debugged, the construction unit should conduct engineering quality acceptance based on its own inspection and evaluation. The acceptance should be initiated by the construction unit and implemented jointly by the construction unit, the owner, and relevant units such as supervision, design, and construction.
② Prior to the quality acceptance of non-standard fire doors, the contractor shall provide the following documents and complete the relevant verification records:- Quality acceptance application report- Quality control check records as specified in the previous basic regulations- Technical documents as specified in the previous basic regulations- As-built drawings and related documents- Records of inspection, installation, and commissioning processes- Records of concealed work acceptance
③ Before the fire door project quality acceptance, a acceptance plan should be formulated according to the acceptance contents and methods specified in this standard. The acceptance personnel should carry out the acceptance according to the acceptance plan and procedures, and should fill in the engineering quality acceptance records in accordance with the requirements.
④ The models, specifications, quantities, and installation locations of non-standard fire doors should comply with the design requirements.
⑤ The acceptance of the fire door installation quality should comply with the relevant regulations regarding the installation of fire doors as described above.
⑥ The acceptance of the fire door control function should comply with the relevant regulations regarding the functionality testing of fire doors as described in the preceding text.
