Light steel keel gypsum board partition walls must have been heard, but not many people really understand. However, when the decoration is finished, they will hear the workers talking about it. Therefore, it is very necessary to know in advance whether the light steel keel plaster board partition wall . Today Xiao Bian came to give you a full overview of the light steel keel plaster board partitions , hoping to help the necessary partners. 
What is a light steel keel plasterboard partition?
The light steel keel is a construction metal skeleton made of high-quality continuous hot-dip galvanized sheet metal and rolled through a cold bending process. It is used for the decoration of non-load-bearing walls and building roofs that are decorated with light-weight plates such as gypsum board and decorative gypsum board. It is suitable for the decoration of various types of building roofs, the interior and exterior walls of buildings, and the basic materials of scaffolding ceilings. According to the use of ceiling keel and partition keel, according to the profile of the V type, C type, T type, L type keel. 
Classification of light steel keel gypsum board partitions
Light steel keel gypsum board partition walls can be divided into single row keel single layer gypsum board partition wall, single row keel double gypsum board partition wall and double row keel double gypsum board partition wall, the former is used for general partition wall The latter two are used for soundproof walls. 
The advantages of light steel keel plasterboard partition wall
1. Dry operation, safety, construction convenience, quickness, on-demand combination, sensitive division of space, easy to remove at the same time. Can effectively save labor and speed up construction progress.
2, light weight, strength to meet the use request. The thickness of gypsum board is usually 9.5-15mm, and the weight per square meter is only 6-12kg. Two steel gypsum board sandwiched between the middle light steel keel is a good partition wall, the wall weight per square meter in 23Kg, only about 1/10 ordinary brick wall. The use of paper gypsum plasterboard as internal wall material can meet the requirements of strength, and the vertical rupture load of paper gypsum board with a thickness of 12mm can reach 500N or more. 
3, reduce income. The chemical and physical properties are stable, and the expansion and contraction rate is small during the dry and moisture absorption process.
4, good decorative effect. The surface layer of the gypsum board partition can be compatible with a variety of surface decoration materials to satisfy the decoration request of most of the functions of the building.
5, economic and reasonable, reduce costs. Compared with ordinary brick-mixed secondary structural walls, it has prevented the formation of cut-outs due to the pre-embedment of water and electricity, preventing the leveling of plasters that were stopped due to the surface decoration practices, and even our work on the wallpaper finishing surface. In addition, plastering and plastering of putty are omitted, which reduces the cost and shortens the construction period, saves resources, and saves money.
6, energy conservation and environmental protection, policy support. 
Light steel keel gypsum board partition wall construction process
1, process flow
Light wall partition line → Install door opening frame → Install keel along the top and keel along the ground → Vertical keel sub-file → Install vertical keel → Install transverse keel card file → Install gypsum panel → Construction joint practice → Surface construction
2. Take off the line: According to the design and construction drawings, place the boundary line of the partition wall, the border line of the door and window opening, and put the top keel position edge line on the ground or ground pillow belt that has been completed.
3. Install the door opening box: After the line is put out, according to the design, install the door opening frame of the partition first.
4. Install the keel along the top and the keel along the ground: Install the top keel and the ground keel according to the placed position line of the partition wall and fix it on the main body with the shot nail. The nail pitch is 600mm. 
5, vertical keel sub-file: According to the location of the partition wall release door, after installing the top keel, according to the specifications of the cover panel 900mm or 1200mm board width, sub-standard size of 450mm, less than the modulus of the sub-file should be avoided The position of the first cover panel at the edge of the door frame is such that the cracked plaster cover panel is not at the hole frame.
6. Install the keel: install the vertical keel according to the bin position, insert the keel along the top keel and the keel along the upper and lower ends of the vertical keel, adjust the vertical and accurate positioning, and fix it with rivets; use the rivets or wood against the wall and the side keel. Screw and wall, column fixed, nail pitch 1000mm.
7, install the transverse stop keel: According to the design requirements, when the height of the partition wall is greater than 3m, horizontal keel shall be added, and rivets or bolts shall be adopted to draw the heart.
8, install the gypsum cover panel 
Light steel keel gypsum board partition quality standards
The provisions of Articles 7.3.9 to 7.4.10 in GB-50210-2001 shall prevail and shall be strictly observed.
Finished protection of light steel keel gypsum board partitions
1. During the construction of the light steel keel partition wall, the working type shall ensure that the installed items are not damaged, and the electric tubes and equipment in the wall shall not touch the misalignment and damage.
2. The light steel skeleton and gypsum plaster board shall enter the site, and shall be properly kept during storage and use so as to ensure no deformation and no pollution or damage.
3. Doors, windows, floors, walls, windowsills, etc. installed on the construction site should be protected and prevented from being damaged.
4. Walls that have been installed must not collide and keep the walls free from damage and contamination.
