Light steel keel partitions are widely used as partitions in our lives. If you have carefully observed them, you will find that light steel keel partitions are used in large areas in terminal buildings, stations, shopping malls, theatres, office buildings, etc. In addition to large public spaces, many small houses also use light steel keel partitions. Today, I will introduce the composition, thickness, price and construction process of light steel keel partition wall in detail

light steel keel partition walls are widely used as partitions in our lives. If you have carefully observed them, you will find that light steel keel partition walls are widely used in terminal buildings, stations, shopping malls, theatres, office buildings, etc. In addition to large public spaces, many small houses also use light steel keel partitions. Today, I will introduce the composition, thickness, price and construction process of light steel keel partition wall in detail

I Components of light steel keel partition wall

light steel keel partition wall is composed of horizontal keel, vertical keel and support card

1. Horizontal keel: generally installed under the floor or on the ground, mainly used to fix the vertical keel

2. Vertical keel: generally used for hanging gypsum board

3. Support card: mainly used to fix through keel and vertical keel

II Thickness dimension of light steel keel partition wall

1. The thickness of single-sided single-layer sealing plate (0.95cm) of 75 type light steel keel partition wall is 8.45cm, and the wall thickness after painting is about 9cm

2. The thickness of double-sided double-layer sealing plate (0.95cm) of 75 type light steel keel partition wall is 9.40cm, and the wall thickness after painting is about 10cm

3. The thickness of single-sided single-layer sealing plate (1.20cm) of 75 type light steel keel partition wall is 8.70cm, and the wall thickness is about 9cm after painting

4. The thickness of double-sided double-layer sealing plate (1.20cm) of 75 type light steel keel partition wall is 9.9cm, and the wall thickness is greater than 10cm after painting

III Construction process flow of light steel keel partition wall

1. Setting out of wall position

snap lines on the floor according to the partition wall position determined by the design drawings, and lead the lines to the ceiling and side walls

2. Construction of skirting board

if it is required to set a skirting board, the base course of the floor should be cleaned first, yj302 interface treatment agent should be painted, C20 plain concrete skirting board should be poured, and the upper surface should be kept flat and the two sides should be vertical, and then according to the design requirements, whether structural reinforcement or embedded parts should be configured in the skirting board should be determined

3. Install the keels along the ground, top and side

the connection between the horizontal keel and the building top and ground, as well as the connection between the vertical keel and the wall and column. Generally, m5*35 shooting nails can be used to fix the keel and the concrete matrix. If the light steel keel is in contact with the surface of the building matrix, a full-length rubber sealing strip should be pasted on both sides of the keel contact surface for waterproof and sound insulation

4. Installation of vertical keel

the vertical keel is usually determined by the width of the cover plate. If the width of the cover plate is large, an additional vertical keel should be added in the middle. The median distance of vertical keel shall not exceed 600mm. The median distance of the vertical keel with heavy covering layer of the partition wall shall not be greater than 420mm. When the height of the partition wall is relatively large, its vertical keel layout shall also be densified accordingly

when installing the vertical keel, it should be arranged from one end of the partition wall, and the doors and windows should be extended from the door and window openings to both sides. If the distance between the last vertical keel and the keel along the wall (column) is larger than the keel mid distance specified in the design, a vertical keel must be added. Push the vertical keel with the cut length between the keel along the top and the keel along the ground, and the flange faces the direction of the cover panel. If the upper and lower ends of the keel are connected by steel columns, fix them with self tapping screws or pop rivets and the horizontal keel. When a perforated vertical keel is used, its up-down direction cannot be reversed. When the vertical keel is cut on site, it must be cut from its upper end, and ensure that the through-hole height of each keel is at the same level

according to the design requirements, the vertical keel at the door and window opening should be installed in a double way or with a box to strengthen the keel. If the door is large and the door and window are heavy, diagonal braces need to be set at the upper, lower, left and right positions outside the door frame

5. Installation of through keel

through punching of through keel across each vertical keel can be extended with supporting connectors. Install a bracket or support card on the open surface of the vertical keel, and connect and lock it with the through horizontal brace keel. An angle bracket can be added on the back of the vertical keel to fix it with the through keel. When using the keel of the support card series, the support card should be installed on the open surface of the vertical keel, with a clamp distance of 400-600mm and a distance of 20-25mm from both ends of the keel

IV The price of light steel keel partition wall

light steel keel partition wall is a relatively economical wall partition. The price varies with the thickness and width of keel materials. Generally, the price of each piece is between 12-20 yuan, and the price of each standard piece of gypsum board (2400mm × 1200 mm) is between 22-30 yuan. Then, according to the different shapes and materials of partition walls, plus the cost of auxiliary materials and labor costs, Generally, the price of light steel keel partition wall is 90-150 yuan/square meter

after reading it carefully, you have a general understanding of the light steel keel partition wall, but if it involves the actual problems of specific home decoration, it is still based on the suggestions of the designer.
