Wiring out According to the construction drawing, place the partition wall azimuth line, door and window opening frame line on the prepared floor or floor pillow belt, and place the top keel azimuth edge line.
After installing the door opening frame, follow the instructions and first install the door opening frame of the partition wall.
Install the top keel and ground keel according to the already placed partition wall orientation line. Install the top keel and ground keel according to the line and fix them on the main body with nails. The nail spacing is
The basis for vertical keel classification. After installing the roof keel, the location of the door opening of the partition wall shall be based on the standard of the cover panel or the board width binning standard. If the binning size is insufficient, it should avoid the position of the first cover panel on the edge of the door opening frame so that the broken edge fireproof board is no longer close to it. At the hole frame.
Install the keel according to the gear position. Install the vertical keel at the upper and lower ends of the vertical keel. Insert the top and bottom keels into the top and bottom keels. After adjusting the straightness and positioning accurately, use rivets to fix the side keels against the wall columns. Use nails or wood screws to connect the keels to the wall columns. The fixed nail spacing is
When installing a transverse retaining keel according to the design requirements, when the partition wall height is greater than 100, a transverse retaining keel should be added and fixed with blind rivets or bolts.
Installing fireproof boards
Check the installation quality of keels to see if the door opening frame meets the design and structural requirements and whether the keel spacing meets the modulus of the gypsum board width.
The paper fireproof board on one side of the installation starts from the door. For walls without door openings, the fireproof board starts from one end of the wall. The fireproof board is usually fixed with self-tapping screws. The distance must not be smaller or larger than the self-tapping screws. When fastening with self-tapping screws, the fireproof board must be close to the keel.
Install electrical pipes, electrical boxes and electrical box equipment inside the wall.
Install the fireproof, soundproof and moisture-proof filling material in the wall together with the paper fireproof board on the other side.
The installation method of the paper fireproof board on the other side of the wall is the same as that of the fireproof board on the first side. The joints should be staggered with the panel on the first side.
When installing a double-layer fireproof board, the fixing method of the second layer is the same as that of the first layer, but the joints of the third layer should be staggered with the first layer and cannot fall on the same keel as the joints of the first layer.
Seaming methods There are three methods for jointing fireproof boards, namely flat seams, concave seams and taped seams. It can be handled in the following order.
Before scraping the caulking putty, remove the floating soil in the joints and use a small scraper to embed the putty into the board seams and fill the board surface with smoothness.
Paste the tie tape and wait for the caulking putty to solidify into its original shape. Post the tie material. First, scrape a thin layer of gelatinous putty with a thin consistency on the joint. The thickness is the width of the tie band and then post the tie tape with a medium scraper. Smooth and compact from top to bottom to drive out the air bubbles between the putty and the bonding tape.
Scrape the middle layer of putty. After pasting the tie tape, immediately scrape another layer of middle layer putty on top of it, which is about 100% thicker than the tie tape, so that the tie tape is buried in this layer of putty.
Leveling putty Use a large scraper to fill the wedge-shaped groove and plate with putty and level it.
Wall decoration fireproof board walls can be decorated with various finishes according to design requirements.
