Installation process of Xuanyuan fire door

2021-09-29 09:31:23

Xuanyuan fireproof door installation tools: electric hammer, woodworking hammer, file, plane, hacksaw, flat screwdriver, angle ruler, ring ruler, plumb bob, etc.

Installation procedure: assembling door frame

(1) On the flat and smooth ground, use a 2.5mm diameter electric drill to lead 30-40mm deep nail holes at the upper end of the mullion, and use four 80mm long yuan nails to firmly connect the transom with the two mullions (the three frame openings are on the same plane; the gap between the inner side of the frame and the connection between the mullion and the transom is less than 0.5mm, and the two transoms form a 90 degree angle with the mullion).

(2) Fix 6 connecting pieces on both sides of the mullion.

(3) Turn the assembled door frame over on the ground and fix the other 6 connecting pieces with yuan nails (check whether the angle is 90 degrees and whether the inner width of the lower and middle three points of the door frame is consistent).

(4) After the inspection meets the requirements, "pre close" the door leaf and the door frame (the side with the seam). The clearance between both sides of the door and the door frame shall meet the requirements.

Connection and fixation of fire door frame and wall

(1) Move the firmly assembled door frame into the door opening as a whole (both sides of the door frame and the wall are on the same plane; check whether the whole door frame is perpendicular to the ground with a plumb bob)

(2) Determine twelve drilling points on the wall by taking the pin hole of the connector as the point.

(3) Use 8-10mm diameter electric hammer to drill holes on the hole points, nail wood wedges in the drilling seeds, and fix the connecting pieces on the wall with yuan nails.

(4) Wooden strips shall be inserted between the fixed door frame and the wall and in the joints to ensure that they are neither too tight nor too loose, so that the door frame and the wall can be connected and fixed.

Install the door leaf

(1) The hinge groove shall be removed, and the decorative surface of the door shall not be damaged during the operation.

(2) Install hinges. Before nailing wood screws, first lead the nail holes, then nail wood screws and tighten them (first tighten a screw on the upper and lower hinges, and then close the door to check whether the gap is in compliance, whether the opening and the door leaf are on the same plane, and whether the door leaf is sagging. Tighten other screws after no mistakes are made, and it is strictly prohibited to "drive" the screws directly into the door leaf frame).

(3) Install the door lock (after the door lock is installed, pay attention to comprehensively check whether the door lock switch is flexible and whether the seam is compliant).

Install door pocket line and door stop strip. (Two in one structure)

(1) A concave installation nail groove is set for both the sleeve line and the baffle strip. The 20-25mm nails are used to fix the door sleeve line shell and the baffle strip shell on the door frame, and then the glue is used to install the strip core of the door sleeve line and the baffle strip on the sleeve line shell and the baffle strip shell.

(2) The door pocket line and the door stop strip shall be cut to a 45 degree angle (pay attention to use a flat file or carpenter's plane to polish the angle, and the joint of the two corners of the angle shall be a line, the joint shall be tight and flat, and the joint shall be firmly glued).

Installation quality standard: overall effect

(1) The door leaf and door lock switch shall be flexible without forming "self opening".

(2) The gaps around the door leaf are consistent.

(3) The connection gap is tight and firm.

(4) The decorative surface is free of damage.

Stitch standard

(1) The gap between the door leaf locking position and the mullion is 3-4mm.

(2) The joint between the door leaf joint side and the mullion is 2-3mm.

(3) The seam between transom and door leaf is 2-3mm.

(4) The joint between the door leaf and the ground is 6-8mm.
