Light steel keel walls are widely used as partitions in our lives. If you look closely, you will find that terminals, stations, shopping malls, theaters, office buildings, etc. are widely used to light steel keel. Wall . In addition to the large public space, in fact, many small houses will also use light steel keel walls. Today small metal frame around the walls of the composition, thickness, size, price, several aspects of the construction process to detail the metal frame wall.
I. Components of light steel keel walls
The light steel keel wall consists of three parts: a horizontal keel, a vertical keel, and a support card.
1. Horizontal keel: generally installed below the floor or on the ground, mainly used to fix the vertical keel.
2, vertical keel: generally used to hang gypsum board.
3, support card: mainly used to fix the piercing keel and vertical keel.
II. Thickness of Light Steel Keel Partitions
The thickness of a single-layer single-layer sealing plate (0.95cm) for type 1 and type 75 light steel keel walls is 8.45cm, and the wall thickness after painting is about 9cm.
The thickness of the double-layer double-layer sealing plate (0.95cm) of the Type 2 and Type 75 light steel keel walls is 9.40cm, and the thickness of the wall after painting is about 10cm.
The thickness of a 3,75-type light steel keel partition wall (1.20cm) is 8.70cm, and the wall thickness after painting is about 9cm.
The thickness of the 4,75-type light steel keel partitions on both sides of the double-layer sealing plate (1.20cm) is 9.9cm, and the wall thickness after painting is greater than 10cm.
III. Light steel keel wall construction process
1, wall position line
According to the partition wall determined by the design drawings, the line is laid on the ground floor and the line is led to the ceiling and the side wall.
2, kick table construction
If you want to set the kick stand, you should first clean up the floor ground floor, brush YJ302 type interface treatment agent, pouring C20 plain concrete kick table, keep the upper surface flat, both sides perpendicular, and then according to design requirements, determine the kick table Whether to configure structural reinforcement or embedded embedded parts.
3, installation along the ground, along the top, along the side keel
The connection between the horizontal keel and the top of the building and the ground, and the connection between the vertical keel and the wall and column, generally M5*35 can be used to fix the keel and the concrete matrix. When the light steel keel is in contact with the surface of the building substrate, a long rubber seal is generally attached to both sides of the keel contact surface for waterproofing and sound insulation.
4, vertical keel installation
The vertical keel is usually set according to the width dimension of the cover panel. If the width of the cover panel is larger, a vertical keel should be added in between. Vertical keel distance is not more than 600mm. The distance between the heavier vertical keel of the partition wall and the vertical wall of the partition wall shall not be greater than 420mm. When the height of the partition wall is relatively large, the vertical keel arrangement shall be encrypted accordingly.
When installing the vertical keel, it should be arranged from one end of the partition wall. The doors and windows should be opened from both the door and the window opening to the sides. If the length of the last vertical keel is larger than the distance between the keels along the wall (pillar), the distance between the keel should be larger than the design. At the time, a vertical keel must be added. Push the length of the vertical keel between the keel along the top and along the ground. The flange faces towards the cover plate. If the upper and lower ends of the keel are connected by steel columns, use the self-tapping screws or rivets and horizontal keel to fix the keel. . When the vertical keel is punched, the vertical direction cannot be reversed. When the vertical keel is cut off at the scene, it must be cut from its upper end, and the height of the through holes of each keel is at the same level.
According to the design requirements, the vertical keel installation at the door and window openings should be double-stranded or buckled to strengthen the keel. If the door is relatively large and the doors and windows are heavy, it is necessary to set diagonal braces at the upper, lower, left and right positions outside the door frame.
5, the installation of consistent keel
Through-hole piercing through each vertical keel can be carried out using matching fittings. Install the bracket or support card on the open face of the vertical keel, and connect it with the through cross keel, and add the corner bracket and the through keel on the back of the vertical keel to fix it. When using the keel of the support card series, the support card should be installed on the open face of the vertical keel with a card distance of 400-600mm and 20-25mm from both ends of the keel.
IV. Prices of light steel keel walls
The light steel keel partition wall is an economical wall partition. The thickness and width of the keel material are different, and the price is not the same. Generally, the price of each keel is between 12-20 yuan, and every standard sheet of plasterboard is The price of 2400mm x 1200mm is between 22-30 yuan. Then according to the different shapes and materials of the partition, plus the cost of auxiliary materials and labor costs, the price of general light steel keel partition wall is 90-150 yuan. / Square meter.
After careful reading, you have a general understanding of the light steel keel partition , but if it comes to the actual problems of specific home decoration, or to the designer's advice, if you want to know if your house is appropriate With a light steel keel partition wall, we can enter our website to consult our designer Ha.
