What are the construction technologies of light steel keel partition wall?

Hearing the name of light steel keel partition wall, many people feel strange. Light steel keel is a new building material, and the light steel keel partition wall is made of this new material. Light steel keel partition wall is light in weight but high in strength. It can prevent fire, sound and shock, and the installation is relatively simple. Therefore, it is widely used in stations, shopping malls, hotels, office buildings, factories, and some indoor decoration or renovation of old buildings. The construction technology of light steel keel partition wall is introduced below, and interested friends can have a look.

1.？ Process flow: pay-off of light partition wall →? Install the door opening frame? —→? Install the keel along the top and the keel along the ground? →? Vertical keel grading? -Installation of vertical keel-Installation of horizontal keel block-Installation of gypsum cover panel-Construction joint practice-Surface construction.

2.？ Setting-out: according to the design and construction drawing, set out the position line of partition wall, the edge line of door and window opening and the edge line of top keel position on the prepared ground or pillow belt.

3.？ Installation of door opening frame: After setting out, install the door opening frame of partition wall as designed.

4.？ Install the top keel and the ground keel: Install the top keel and the ground keel according to the line of the partition wall, and fix them on the main body with nails, with the nail spacing of 600 mm ..

5.？ Vertical keel grading: according to the position of the entrance of the pay-off door of the partition wall, after the top keel is installed, the grading size is 450mm according to the specifications of the cover panel of 900mm or1200 mm. The grading with insufficient modulus should avoid the position of the first cover panel at the edge of the door opening frame, so that the broken gypsum cover panel is not at the door opening frame.

6.？ Installation of keel: install vertical keel according to the slope position, insert the upper and lower ends of vertical keel into the top keel and the ground keel respectively, and fix them with core-pulling rivets after vertical adjustment and accurate positioning; The wall column keel is fixed with nail or wood screw, and the nail distance is1000 mm.

7.？ Installation of transverse retaining keel: According to the design requirements, when the height of partition wall is more than 3m, transverse retaining keel should be added and fixed with directional core-pulling rivets or bolts.

8.？ Installing gypsum cover plate

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

2)? Gypsum board is installed on one side, starting from the door, and the wall without door opening starts from one end of the wall. Gypsum board is generally fixed with self-tapping screws, with the nail spacing of 200mm at the edge of the board and 300mm in the middle of the board. The distance between the screw and the edge of gypsum board shall not be less than 10mm, nor greater than 16 mm. When self-tapping screws are fixed, gypsum board must be nailed with keel.

3)? Install electrical pipes and boxes and equipment in the wall.

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

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

6)? Installation of 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 from the first layer and cannot fall on the same keel with the joints of the first layer.

9.？ Joint practice: there are three forms of joint practice of gypsum board, namely flat joint, concave joint and layering joint. Can be handled according to the following procedures.

1)? Scraping caulking putty: before scraping caulking putty, clean up the floating soil in the joint, embed the putty in the joint with a small scraper, and fill it with wooden boards and scrape it flat.

2)? Bonding tie: Bonding tie material as soon as caulking putty solidifies. First, scrape a thin layer of colloidal putty with the thickness of 1mm and the width of the strap at the joint, then paste the strap, scrape it flat and compact it from top to bottom with an intermediate scraper to drive out bubbles between the colloidal putty and the strap.

3)? Scraping intermediate putty: Immediately after pasting the adhesive tape, scrape a layer of intermediate putty with a thickness of about 1mm, which is about 80mm wider than the bandwidth of Rachel, so that the Rachel tape is buried in this layer of putty.

4)? Scraping putty: Fill the wedge groove with putty with a big scraper and scrape the board flat.

10.？ Wall decoration, gypsum board wall, according to the design requirements, can do a variety of finishes.

The above process is the construction technology of light steel keel partition wall, and the construction personnel should take a closer look. In the process of construction, the required materials, accessories and construction tools should be ready, and don't be blind for a while. There is also the need to pay special attention to some quality problems. For example, the deformation of the wall, the cracks in the board, the weak connection of the skeleton, and the inequality of the wall cover panel. These problems are very serious and directly affect the construction quality. After the problem occurs, it should be repaired in time and bear the responsibility of construction project. Any construction process in decoration requires us to strictly check, find problems in time and rework in time, but without professional decoration knowledge, it is difficult to check the construction effect. At this time, we need professional decoration supervision to help us check the construction process.
