Introduction to the construction technology of light steel keel partition walls

Many people feel unfamiliar when they hear the name light steel keel partition wall. Light steel keel is a new type of building material, and light steel keel partition walls are made of this new material. Light steel keel partition walls are very light in weight but very strong. They can be fireproof, soundproof, and shockproof, and are easy to install. Therefore, it is widely used in stations, shopping malls, hotels, office buildings, factories, as well as some interior decoration or renovation of old buildings. Next, we will introduce the construction technology of light steel keel partition walls. Interested friends can take a look.

1. Process flow: Laying out the light partition wall—→ Installing the door opening frame—→ Installing the top keel and ground keel → Vertical keel staging?—→ Installing the vertical keel Toward the keel—→Install the transverse keel clip—→Install the gypsum cover panel—→Construction joint practices—→Surface layer construction.

2. Lay out the lines: According to the design and construction drawings, lay out the partition wall position lines, door and window opening frame lines, and place the top keel position edges on the prepared ground or floor pillow belt.

3. Install the door opening frame: After laying out the wiring, first install the door opening frame of the partition wall according to the design.

4. Install the top keel and ground keel: According to the location line of the partition wall, install the top keel and ground keel according to the line, and fix it to the main body with nails. The distance is 600mm.

5. Vertical keel grading: According to the position of the partition wall setting door opening, after installing the top keel, according to the specification of the cover panel, the board width is 900mm or 1200mm, and the grading specification is 450mm, which is insufficient. The grading of modules should avoid the position of the first cover panel on the edge of the door opening frame, so that the broken edge gypsum cover panel is not at the door opening frame.

6. Install the keel: Install the vertical keel according to the graded position. Insert the upper and lower ends of the vertical keel into the top keel and the ground keel. After adjusting the verticality and positioning accurately, fix it with rivets; walls and columns The side keel is fixed to the wall and column with nails or wood screws, and the nail distance is 1000mm.

7. Install transverse blocking keels: According to the design requirements, when the height of the partition wall is greater than 3m, transverse blocking keels should be added and fixed with blind rivets or bolts.

8. Install the gypsum cover panel

1) Check the installation quality of the keel, whether the door opening frame meets the design and construction requirements, and whether the keel spacing meets the modulus of the gypsum board width.

2) Install the gypsum board on one side, starting from the door. For walls without door openings, start from one end of the wall. The gypsum board is generally fixed with self-tapping screws. The nail distance between the board edges is: 200mm, the distance between the boards is 300mm, the distance between the screws and the edge of the gypsum board shall not be less than 10mm, nor greater than 16mm. When fixing with self-tapping screws, the gypsum board must be nailed tightly to the keel.

3) Install electrical pipes, electrical boxes and electrical box equipment inside the wall.

4) Install fire-proof, sound-insulating and moisture-proof filling materials in the wall, and install and fill them in at the same time as the gypsum board on the other side.

5) Install the gypsum board on the other side of the wall: The installation method is the same as the gypsum board on the first side, and the joints should be staggered with the first side panel.

6) Install double-layer gypsum 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 not with the first layer. The seams of the layers fall on the same keel.

9.?Joining methods: There are three forms of gypsum board jointing methods, namely flat seams, concave seams and batten seams. It can be handled according to the following procedures.

1) Scrape the caulking putty: Before scraping the caulking putty, clean the floating soil in the joints first, use a small scraper to embed the putty into the seams of the board, and fill it with the board surface.

2) Paste the tie tape: After the caulking putty solidifies, the tie material can be pasted. First, scrape a thin layer of gelatinous putty with a thin consistency on the joint, with a thickness of 1mm and a width of Pull the tie wide, then stick the tie tape, use a medium scraper to flatten and compact it from top to bottom, and drive out the air bubbles between the glue putty and the tie tape.

3) Scrape the middle layer of putty: After the tie tape is pasted, immediately scrape a layer of middle layer putty about 1mm thicker than the tie tape, which is about 80mm wider than the tie tape, so that the tie tape is buried in this layer of putty. .

4) Leveling putty: Use a large scraper to fill the wedge-shaped groove and plate with putty and level it.

10. Wall decoration and gypsum board walls can be made into various finishes according to design requirements.

The above process is the construction process of light steel keel partition walls. Construction personnel should take a careful look. During the construction process, the required materials, accessories and construction tools must be fully prepared, so as not to be blinded by the time. There are also some quality issues that need to be paid special attention to. For example, wall deformation and panel cracks, weak frame connections, and uneven wall covering panels. These problems are serious and directly affect the quality of construction. After problems occur, they must be repaired in time and bear responsibility for the construction project. Any construction process during decoration requires our strict inspection, timely discovery of problems, and timely rework. However, it is difficult to check the construction effect without professional decoration knowledge. At this time, we need professional decoration supervision to help us control the construction process. We can apply Tubatu Decoration Warranty, the decoration guarantee includes professional quality inspection services, which can provide one-on-one home decoration consultants and help owners quickly safeguard their rights during decoration!
