The fire wall actinomycetes - → installation of the door opening frame - → device along the top of the keel and keel along the keel → vertical binning - → means vertical keel - → means lateral keel card file - → means plaster cover panel - → Construction seams practice - → Surface Construction 2. actinomycetes: According depict construction plans, has been doing to bring pillows on the floor or ground, release the line of bearing walls, door and window openings border line, and put away Top keel bearing edges. 3. The apparatus of the door opening frame: After actinomycetes by depicting the end of the door opening frame means the first partition. 4. The device along the top of the keel and keel along: they have already put away the wall bearing line, according to wire-bound top keel and keel, with a nail fixed to the main body shot nail vertical distance of 600mm 5. keel points. file: According to the partition actinomycetes door opening position, at the top of the keel after the device, according to the cover panel of the standard 2400mm or 1220mm plate width, sub-file standard scale of 610mm, the lack of modulus of sub-file should avoid the top edge of the door opening frame block cover panel orientation, so that is not broken by the hole edge Firewood box office. 6. The device keel: Press binned orientation means vertical keel, vertical keel up and down along the top of the keel and two pierced along the keel, after adjusting the straight and precise positioning with pumping heart rivets; wall, pillar side of the keel, or wood with a nail Screws and walls, columns fixed, nail distance of 1000mm 7. keel block of Lateral card: according to depict demand, wall height greater than 3m card file should be added lateral keel, taken to heart pumping rivets or bolts. 8. The device Firewood: (1): View keel means quality, the door opening frame and structural requirements can fit depict keel interval modulus can fit the width of the gypsum board. (2) means the paper side of the fire board, from the beginning of the door, nowhere by the end of the beginning of the hole in the wall the wall, Firewood is usually self-tapping screws, nails from the board edge for 200mm, 300mm intervals board screw spacing from the fire board not less than marginal 10mm, nor more than 16mm, self-tapping screws stick, the fire board and keel immediately necessary. (3) the apparatus wall electrical pipes, electrical boxes and electrical boxes devices. (4) means the wall of fire, sound insulation, moisture-filled data, and the other side of the paper together with the means to fill the fire board. (5) the other side of the device wall paper Firewood: means approach with the top side of the fire board, the joints should be staggered with the top side of the board. (6) means double Firewood: fixed way with the top layer of the second sheet of the same, but the third laminate joints should be staggered with the top layer, the top layer of the seam can not fall on the same keel. (7) The joint practice: Firewood joint approach in three ways, namely, flat seam, dents and press seam. Can be disposed in the following order. (8) scraping putty caulking: scraping putty caulking seams topsoil eradicate before the first clean, with a small spatula putty embedded in the slab, and the board tamped gelling. (9) Post Rachel with: caulking putty to be the prototype of condensation that line then pull the information posted, first scrape a layer of thin seam in the more dilute gel consistency of putty, a thickness of 1mm, the width of the bandwidth for Rachel, then posted pick Ribbon, with the blade in one direction from the top down Calibrating compaction, expelled bubble gum putty and tying belt. (10) Middle scraping putty: Rachel with post after layer immediately above Zaigua Rachel bandwidth than about 80mm thickness of about 1mm middle putty, so Rachel belt buried in this layer of putty. (11) leveling putty: putty with a large spatula to fill the slot with the wedge plate smooth. (12) Wall embellishment, Firewood walls, depicting demand basis, do a variety of finishes.
