Construction method of gypsum board partition wall
1. Positioning and setting-out of partition wall. According to the architectural design, the partition line and sideline will pop up on the floor of the indoor building, and lead to the bottom of the two main structures, and at the same time pop up the door and window opening line.
2. Install the horizontal keel (lower sill) along the ground and fix it with nails, or drill holes first and fix it with expansion bolts. When installing, it should be installed according to the line and sideline, and both ends should be pushed to the surface of the structural wall (column), and the later fixed point should be no more than100 mm from the structural facade; The spacing between nails or expansion bolts should not be greater than 800 mm, and the levelness and straightness of the keel should be guaranteed during installation.
3. Install the top transverse keel (upper sill), and the installation along the top keel is the same as that along the earthworm.
4. Install the vertical keel along the wall (column). The fixed connection between the vertical keel of the partition frame and the building structure wall is the same as that along the top and along the ground.
5. Install the vertical keel. Based on the threading holes on the C-shaped vertical keel, first determine the direction of the upper and lower ends of the keel, and try to align the threading holes. The length and size of vertical keel shall be subject to the measured size on site. ; After the vertical keel is installed in place, it should be vertical. Doors and windows openings should be strengthened and fixed with double rows of vertical keels. When the design requires rigid connection, the vertical keel and the top keel along the ground should be connected by self-tapping screws or axial rivets.
6. Install the through-hole keel and cross brace. When the partition wall adopts a series of through-hole keels, the vertical keels shall be installed with through-hole keels and pass through the through-hole of each vertical keel in the horizontal direction. Angle codes are mainly used to connect the cross brace keel and the vertical keel. The angle codes are fixed on the back of the vertical keel with axial rivets or self-tapping screws, and can also be connected to the opening surface of the vertical keel with Cato.
7, doors and windows and other node skeleton installation, for the partition skeleton parts, can use additional keel or buckle box to strengthen the keel, should be installed and fixed according to the design drawings. Decorative wooden door frames are usually fixed on the vertical keel of the hole with self-tapping screws, as is the connection between the cross beam of the door frame and the horizontal keel.
Construction skills of gypsum board partition wall
1, fire-resistant gypsum board must choose products that meet China's fire protection standards. The length is the height of the whole space, and the width is 900 or 1200mm. Thickness according to the design requirements, the installation of partition wall should be carried out after the completion of roofing, floor, indoor plastering, glass and other processes.
2. This project is a single-layer gypsum board partition wall. Gypsum boards are arranged vertically. Gypsum boards on both sides of the keel should be staggered. The joint surface of gypsum board adopts concealed joint. Gypsum board has wedge-shaped edges, and SG building glue is used for bonding gypsum board and gypsum keel.
3. When the door opens to the gypsum board partition, a door stop device, such as a door bump or a door stop, should be set to prevent the door handle from hitting and damaging the partition.
4. See the manufacturer's atlas for the wall structure. The partition wall is connected with the roof by means of auxiliary gypsum keel, and the keel spacing is determined according to the width of gypsum board. Then the upper part of the vertical keel is pressed on the auxiliary keel, and the lower part is supported by wooden wedges and stays. Finally, plaster the board. Sticking plate must be carried out after the final setting of keel bonding (not earlier than 4h).
5. Within 30mm width around the plate, evenly coat 3 ~ 5mm thick adhesive on the keel. Push and squeeze the plate tightly, and knock with a rubber hammer to make the plate and keel closely combined. After pasting the panel, immediately check whether the wall is flat and vertical, and correct it in time when problems are found. After pasting, clean up the sundries at the joint of the plate, embed the putty into the flat plate, scrape the putty at the bottom of the joint about 1mm thick after the final setting of caulking, then immediately paste the joint tape, compact and scrape it with one operation, and scrape the putty on the joint tape with one big operation when the putty is initially set.
Construction is a very complicated matter, so we must have a certain understanding in advance, so that we can easily face the decoration. Bian Xiao told everyone about the concrete construction method of gypsum board partition wall and some tips that can be used, so that everyone can use it during construction.
