1) light steel keel is generally used for ready-to-install gypsum board partition wall, can also be used for cement particle board partition wall, straw board partition wall, fiberboard partition wall. Different types and specifications of light steel keel, can be composed of different partition wall skeleton. Structure. Generally, along the ground, along the top keel and along the wall, along the column keel (with vertical keel) constitutes a partition wall frame, the center of a number of vertical keel, it is the main load-bearing keel. Some types of light steel keel, but also to add through the horizontal support keel and strengthen the keel; vertical keel spacing according to the width of the gypsum board, generally in the gypsum board board edge, the board is placed in one, the distance is not greater than 600mm; when the wall decoration layer quality is large, such as ceramic tiles, the keel spacing is not greater than 420mm is appropriate; when the height of the wall to be higher, the keel spacing should be appropriately narrowed.
Light partition wall has limit height. It is based on the section of light steel keel, stiffness and keel spacing, wall thickness, gypsum board layers.
2)The partition wall skeleton construction is determined separately by different keel types or systems according to the partition wall requirements.
3)Different parts and different keel fixing methods and ways:
①Border keel (including along the ground keel, along the top keel and along the wall, column keel) and the main structure fixed. General use of nail technology, that is, according to the distance & lt; 1.0m into the nail and the main structure of the fixed, can also be used to drill holes into the expansion bolts or in the main structure of the method of leaving embedded parts,
② vertical keel and pull rivets along the top, along the ground keel fixed.
3 door frame and vertical keel connection. Depending on the type of keel has a variety of practices, there are ways to strengthen the keel and wooden door frame connection, can also be used to extend the sides of the wooden door frame upward, inserted along the top of the keel and vertical keel, can also be used in other ways of fixing,
4) round curved partition wall wall construction, according to the curved surface requirements will be along the ground, along the top of the keel sawn into a sawtooth shape, fixed in the top surface and the ground, and then arranged according to the smaller spacing (generally 150mm) vertical keel and pull rivets. 150mm) arrangement of vertical keel.
Light steel keel gypsum board partition wall, the main materials and accessories requirements
1. Light steel keel main parts: along the top keel, along the ground keel, strengthening keel, vertical keel, horizontal keel should be in line with the design requirements.
2. Light steel skeleton accessories: support card, card bracket, corner bracket, connectors, fixings, attached to the wall keel, pressure strip and other accessories should be in line with the design requirements.
3. Fastening materials: nail, expansion bolts, galvanized self-tapping screws, wood screws and bonding inserts should meet the design requirements.
4. Filling sound insulation materials: selected according to design requirements.
5. Covering board: paper-faced gypsum board specifications, thickness selected by the designer or according to the drawings.
Two, the main machine
Direct current welding machine, electric toothless saw, electric drill, screwdriver, nail gun, wire drop, ruler and so on.
Three, working conditions
1. light steel frame, gypsum panel partition wall construction should be completed before the basic acceptance, gypsum panel should be installed after the completion of the roof, ceiling and wall plastering.
2. When the design requires the partition wall to have a pillow belt, it should wait until the construction of the pillow belt is completed and reach the design degree before the light steel skeleton installation.
3. According to the design and construction drawings and material plans, check all the materials of the partition wall, so that it is complete.
4. All materials, must have material testing report, certificate of conformity.
Four, operation process
1. process
Light partition wall line -→ installation of door opening frame -→ installation along the top keel and along the ground keel →
vertical keel stall -→ installation of vertical keel -→ installation of horizontal keel card file. → Installation of horizontal keel card file -→
Installation of gypsum cover panel -→ Construction joints -→ Surface construction
2. Laying out the line: According to the design and construction drawings, on the ground or ground pillow tape, put out the partition wall position line, door and window opening border line, and put the top keel position edge line. Position edge line.
3. Installation of door opening frames: After placing the line according to the design, the door opening frames of the partition wall will be installed first.
4. Installation along the top keel and along the ground keel: according to the position line of the partition wall that has been put in place, install the top keel and
ground keel according to the line, and fix it on the main body with the nail, and the nail distance of the nail is 600mm.
5. Vertical keel staggering: according to the position of the door opening of the partition wall release line, after installing the top keel, according to the specification of the cover panel of 900mm or 1200mm width, staggering specification size is 450mm, and the width is 600mm, and the size is 600mm. After installing the top floor keel, according to the specification of cover panel 900mm or 1200mm board width, the specification size of the sub-stage is 450mm, and the sub-stage of the insufficient modulus should avoid the position of the first cover panel on the side of the door opening frame, so that the broken edge gypsum cover panel is not at the hole frame.
6. Installation of keel: install vertical keel according to the position of sub-stage, insert the upper and lower ends of vertical keel along the top keel and along the ground keel, adjust the vertical and positioning accurately, and then fix it with extracted rivets; against the wall, column side keel with nail or wood screws and wall, column fixed, nail distance is 1000mm.
7. Installation of transverse blocking keel: according to the design requirements, the height of the partition wall is more than 3m should be added when the transverse blocking keel. Transverse blocking keel, pick to the center rivet or bolt fixing.
8. Installation of gypsum panel
1) Check the installation quality of keel, whether the door opening frame is in accordance with the design and structural requirements, whether the spacing of keel is in accordance with the modulus of the width of gypsum board.
2) Installation of one side of the paper-faced gypsum board, starting from the doorway, the wall without door opening from the end of the wall, the gypsum board is generally fixed with self-tapping screws, the board edge nailing distance of 200mm, the board in the middle of the spacing of 300mm, the screw from the edge of the gypsum board distance shall not be less than 10mm, and shall not be greater than 16mm, the self-tapping screws are fixed, the paper-faced gypsum board must be tightly attached to the keel.
3) Installation of electrical pipes, electrical boxes and electrical box equipment in the wall.
4) Install fireproof, sound insulation and moisture-proof filler material in the wall, and fill in with the other side of the paper-faced gypsum board at the same time.
5) Installation of the other side of the wall paper-faced gypsum board: the installation method is the same as the first side of the paper-faced gypsum board, the joints should be staggered with the first side of the board.
6) Installation of double-layer paper-faced gypsum board: the fixing method of the second layer of the board is the same as the first layer, but the joints of the third layer of the board should be staggered with the first layer, and the joints of the first layer should not fall on the same keel.
9. Seam practice: there are three forms of paper-faced gypsum board seam practice, i.e., flat seam, concave seam and compression strip seam. It can be handled according to the following procedures.
1) Scrape the joint putty: scrape the joint putty before removing the floating soil in the joint
2) Scrape the joint putty: scrape the joint putty before removing the floating soil in the joint
