Light steel keel is a new type of construction material, light steel keel partition is a partition wall made of this new material. This new partition wall is widely used in various occasions. Although light weight and high strength, it can be fireproof, soundproof, shockproof and easy to install. Today, I will lead you to understand the construction process of light steel keel partition wall.
Lightweight steel keel partition wall construction process details
Lightweight steel keel partition wall construction process:
1, process flow
Lightweight partition wall release line - → Installation of the door hole frame - → Installation of the keel along the top Along the ground keel → Vertical keel boxing - → Installation of vertical keel - → Installation of horizontal keel card - → Installation of gypsum cover plate - → Construction joints to practise - → Surface Construction.
2, release the line
According to the design and construction drawings, on the completed floor or floor pillow tape, loose the position line of the partition wall, the boundary line of the door and window, and place the top keel position edge.
3. Install door opening frames
After laying the lines, install the opening frames of the partition wall as designed and first.
4. Install the keel along the top keel and keel along the ground
Install the keel according to the position line of the partition wall that has been placed, install the top keel and the ground keel according to the line, and fix the keel to the main body with the keel Nail, the distance of the nails is 600mm. ...
5, vertical keel division
According to the location of the doorway of the dividing wall, after installing the top keel, according to the specifications of the cover plate 900mm or 1200mm, the size of the sub-profile is 450mm, less than the modulus box should avoid the first cover plate is located at the edge of the door frame in order to make the broken gypsum cover plate is not on the door frame.
6, install the keel
Install the vertical keel according to the location of the split position. Insert the top and bottom keel of the vertical keel along the top keel and keel along the ground. After adjusting the vertical and positioning accuracy, fixed with rivets; use rivets as the side of the walls and columns. Nails or wood screws are fixed on walls and columns with 1000mm spacing between nails.
7. Install horizontal locking keel
According to the design requirements, when the height of the partition wall is more than 3m, the horizontal card keel should be added and rivets or bolts should be fixed.
8. Installation of gypsum cover
1) Acceptance of the installation quality of the keel, open the door frame in accordance with the design and construction requirements, as well as the spacing of the keel in accordance with the modulus of the width of the gypsum board.
2) Install gypsum board on one side. Start at the doorway, and walls without door openings start at one end of the wall. Plasterboard is usually fixed with self-tapping screws. The distance between the board nails is 200mm. For 300mm, the distance between the screws and the edge of the gypsum board should not be less than 10mm and not more than 16mm. When the self-tapping screws are fixed, the gypsum board must be fastened with a keel.
3) Installation of wall pipes, electrical boxes and electrical box equipment.
4) Install fireproof, soundproof and moisture-proof filler material on the wall and install it at the same time with the plasterboard on the other side.
5) Install the other side of the wall with gypsum board: the installation method is the same as the first side of the gypsum board, and the joints should be staggered with the first side of the board.
6) Installation of double-layer gypsum board: the second layer is fixed in the same way as the first layer, but the joints of the third layer should be staggered with the first layer and not separated from the first layer. On the same keel.
9, jointing practice
There are three forms of gypsum board joints, i.e., flat joints, concave joints and bead joints. It can be handled as follows.
1) Scraping putty: remove the floating soil at the joints before scraping off the putty. Use a small spatula to insert the putty into the joint and fill it with surface.
2) adhesive knotting tape: the original shape of the putty putty should be pasted adhesive. First, scrape a thin layer of consistency gel putty on the joint. Thickness of 1 mm, the width of the knot width. Paste the tie and use the center scraper to scrape the plane from top to bottom to remove air bubbles between the putty and the tie.
3) Scrape off the intermediate layer of putty: Immediately after pasting the tie, scrape off a layer of intermediate layer of putty with a thickness of about 1 mm and a thickness of about 80 mm, so that the tie can be buried here A layer of putty.
4) Leveling putty: fill the wedge with a large notch and fill the wedge with a wedge.
10, veneer
Wall decoration, gypsum board walls, according to the design requirements, can be used for a variety of finishes.
Light steel keel partition wall construction process
In the light steel keel partition wall construction process, special attention should be paid to some quality problems, such as wall deformation and panel cracks, skeleton connection is not solid, and wall panels are not equal. These problems are more serious and directly affect the construction quality. I have read the introduction, I believe everyone has a simple understanding of the construction process of light steel keel partition wall.
