Light steel keel plasterboard partition has been widely used at different occasions, such as shopping mall, hotel, station and other places, to space, usually can use light steel keel plasterboard partition, the advantage of the ceiling of light steel keel plasterboard partition, condole and construction technology.
The advantage of light steel keel plasterboard partition.
1, safe, convenient and fast construction, high flexibility, can arbitrarily divide the space, and easy to dismantle. It effectively saves manpower and speeds up construction progress.
2, light weight, high strength. The ply of plasterboard is 9.5-15mm commonly, but every square metre weight has 6-12Kg only. With two pieces of paper plasterboard covering in light steel keel formed a very good partition effect. This kind of wall weight per square meter in 23Kg, only for the common brick wall 1/10 or so. Moreover, the strength of plasterboard can also meet the requirements by using plasterboard as the inner wall material. The longitudinal fracture load of plasterboard with thickness of 12mm can reach more than 500N.
3. Good decoration effect. Plasterboard partition wall modelling diversity, decorate convenient. Its face layer can be compatible with a variety of face layer adornment material, satisfy the adornment requirement that great majority building uses a function, can be used at room, meeting room commonly, the room that often uses water can use waterproof plank, the space that needs to notice fire prevention also can choose fire prevention plank.
4, reasonable economy, reduce waste. Compared with ordinary brick wall, light steel keel partition can be avoided due to water and electricity reserve embedded stuck between the chisel, and because of surface decoration practices of plaster leveling assignments, and omits the gypsum during the wallpaper architectural surface operations, putty, paint job, thus reducing the cost and shorten the time limit for a project, and save resources, avoid waste.
5, shrink. The chemical and physical properties of gypsum board are stable. In the process of drying and moisture absorption, the expansion rate is small, which effectively overcomes the defects of joint cracking caused by the expansion of other lightweight boards in the process of use. And because of its own structure can be easily set deformation joints, so it can be used for prone to slight displacement or slight vibration parts.
Light steel keel gypsum board partition construction technology
1. Technological process
Light partition line – - – install the door entrance frame – - – - install along the top keel and along the keel – - vertical keel classification? -→ installation of vertical keel -→ installation of horizontal keel clip -→ installation of plaster cover panel -→ construction of joints -→ surface construction
2. Wiring: according to the design construction drawing, in the ground or pillow belt has been done, release the partition position line, the border line of the door and window hole, and put the top keel position line.
3. Install the door opening frame: After wiring out, install the door opening frame of the partition wall according to the design.
4. Install along the top keel and along the ground keel: install the top keel and ground keel according to the position line of the partition wall, and fix them on the main body with shooting nails, and the shooting nail distance is 600mm.
5. Vertical keel grading: according to the location of the opening of the partition line door, after installing the top ground keel, the grading specification and size are 450mm according to the plate width of 900mm or 1200mm according to the specifications of the cover panel. The grading with insufficient module should avoid the position of the first cover panel at the edge of the door frame, so that the broken plaster cover panel is not near the hole frame.
6. Install the keel: install the vertical keel according to the file position, insert the upper and lower ends of the vertical keel along the top keel and along the ground keel, adjust the vertical and accurate positioning, fixed with rivets; The keel is fixed with the wall and column side by shooting nails or wood screws, and the nail distance is 1000mm.
7. Install the transverse clamp keel: according to the design requirements, when the partition height is greater than 3m, the transverse clamp keel should be added and fixed by pulling rivets or bolts.
8. Install the plaster cover panel
1) Check whether the keel installation quality, the door opening frame meets the design and structural requirements, and whether the keel spacing meets the modulus of the gypsum board width.
2) Installed on the side of the gypsum board, starting from the doorway, unable to the mouth of the cave wall from one end of the wall, plasterboard commonly used self-tapping screws, nail plate edge distance is 200 mm, plate spacing is 300 mm, the screw distance from the edge of the gypsum board shall not be less than 10 mm, also shall not be greater than 16 mm, self-tapping screws, drywall must close and keel.
3) Install electric pipes, electric boxes and electric box equipment in the wall.
4) Install fireproof, sound-proof and moisture-proof filling materials in the wall, and install and fill the gypsum board on the other side at the same time.
5) Install the paper gypsum board on the other side of the wall: the installation method is the same as the paper gypsum board on the first side, and its joints should be staggered with the first side panel.
6) installation of double layer paper gypsum board: the fixing method of the second layer board is the same as that of the first layer, but the joints of the third layer board should be staggered with the first layer, and the joints of the first layer can not fall on the same keel.
9. Seam practice: there are three forms of gypsum board seam practice, namely flat seam, concave seam and layering seam. It can be handled according to the following procedures.
1) scraping and caulking putty: before scraping and caulking putty, remove the floating soil in the joint, insert the putty into the plate seam with a small scraper, and fill the plate and scrape flat.
2) paste the tie belt: to be stitched putty solidification prototype that is, paste the tie material, first thin on the joint
Scrape a layer of thin consistency of the adhesive putty, the thickness is 1mm, the width is the width of the knot, then paste the knot belt, with a scraper from the top to the next direction scraping compaction, drive out the bubble between the putty and the knot belt.
3) scraping middle putty: after the tie belt is pasted, immediately blow a layer of middle putty with a width of about 80mm and a thickness of about 1mm, so that the tie belt is buried in this layer of putty.
4) Leveling putty: use a large scraper to fill the putty wedge groove and flatten the board.
10. Wall decoration, plasterboard wall, according to the design requirements, can do a variety of finishes.
