The light steel keel gypsum board is a combination of a gypsum board and a light steel keel to form a light steel keel gypsum board. Gypsum board is a kind of material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, easy processing, sound insulation, fire prevention and so on. It is one of the new lightweight panels currently under development. Next Xiaobian will introduce light steel keel gypsum board partition wall operation technology.
First, the main materials and accessories requirements
1. Light steel keel main parts: along the top keel, along the keel, strengthen keel, vertical keel, transverse keel should meet the design requirements.
2, light steel skeleton accessories: support card, Cato, corner bracket, connectors, fixtures, wall keel, bead and other accessories should meet the design requirements.
3, fastening materials: nails, expansion bolts, galvanized tapping screws, wood screws and adhesive caulking materials should meet the design requirements.
4, filled with sound insulation material: according to design requirements.
5, cover plate: paper gypsum board specifications, thickness selected by the designer or according to the requirements of the drawings.
Second, the operating conditions
1. Before the construction of the light steel frame and gypsum cover panel partition wall, the basic acceptance work shall be completed. The installation of the gypsum cover panel shall be completed after the completion of the roofing, ceiling and wall plastering.
2. When the design requires that the partition wall has pillows, it should be installed after the construction of the pillows and the design requirements are met.
3. According to the design drawing and material plan, verify all the materials of the partition wall and make it complete.
4, all materials must have a test report, certificate.
Third, the operating process
1. Take off the line: According to the design and construction drawing, 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 made.
2. Install the door opening frame: After the line is put in, the door opening frame of the partition wall is installed first according to the design.
3. 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.
4, vertical keel sub-file: According to the location of the partition wall release door hole, 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.
5. Install the keel: install the vertical keel according to the shift position. Insert the keel along the top keel and the keel along the upper and lower ends of the vertical keel. After adjusting the vertical and the positioning accuracy, fix it with rivets; use the rivets or wood against the wall and the side keel. Screw and wall, column fixed, nail pitch 1000mm
6, install the horizontal card file keel: According to the design requirements, the height of the partition wall is greater than 3m should be added horizontal card file keel, with a riveting heart or bolts.
7, seam practices: There are three forms of gypsum board joints, that is, flat seams, concave seams and pressure strip seams. Follow the procedure below.
Scrape the seam putty. Before cleaning the putty, the floating soil in the joint shall be removed, and the putty shall be embedded in the plate with a small spatula.
Stick a pull tie. After the caulking of the putty, the brazing material can be pasted, and a thin thick consistency gel-like putty is firstly scraped on the seam, the thickness is 1 mm, the width is the width of the pull knot, and the tying tape is then affixed, and the squeegee is used. The next direction is squeezing and compacting to drive out the air bubbles between the glue putty and the tie band.
Scratch the middle putty. After the tying tape is affixed, a layer of intermediate putty with a thickness of about 80 mm and a thickness of about 1 mm is pulled on the top immediately so that the tying tape is buried in the putty.
Leveling putty. Use a large squeegee to fill the wedge groove with the putty.
8, wall decoration, plasterboard wall, according to design requirements, can do a variety of finishes.
Fourth, product protection
1. During the construction of the light steel keel partition wall, the working type shall ensure that the installed project is not damaged, and the electric pipe and equipment in the wall shall not touch the dislocation and damage.
2. The light steel skeleton and gypsum plasterboard shall be properly kept during storage and use to ensure no deformation, moisture, pollution or damage.
3. Doors, windows, floors, walls, windowsills, etc. installed in the construction site should be protected and prevented from being damaged.
4. Walls that have been installed may not collide and keep the walls free from damage and contamination.
Fifth, pay attention to the quality of the problem
1. Wall shrinkage deformation and board surface cracks: The reason is that the vertical keel tightly covers the upper and lower keels, and no telescopic amount is left. The wall that exceeds 2m in length does not control the deformation joints, causing wall deformation. A 3mm gap should be left around the partition wall to reduce distortion and cracks caused by temperature and humidity.
2. The connection of the light steel skeleton is not firm because the local nodes do not conform to the construction requirements and the local nodes should be strictly handled according to the drawings. The nail spacing, location, and connection method should meet the design requirements.
3. The unevenness of the wall cover panel is mostly caused by two reasons: one is the lateral misalignment of the keel installation, and the other is that the thickness of the gypsum board is inconsistent.
4. Uneven uneven groove: Gypsum board is difficult to grasp the size of the joints. Pay attention to the size of the partitions during construction to ensure that the joints between the boards are consistent.

Short Radius Elbow refers to that the radius of curvature is 1 times of the elbow pipe diameter,also referred to as 1D.
Elbow push hot forming process is the use of special elbow pushing machine, mandrel and the heating device, so that pushing pipe raw material to forward movement in the mold set, be heated in motion, expanding and bending forming process. Elbow push hot deformation characteristics of tube diameter is determined according to the law of constant volume before and after deformation of the metal material, use smaller diameter than the diameter of the elbow, through mandrel to control the deformation process of the blank, to other parts of the compensation due to thinning of the diameter expands, thereby obtaining a uniform wall thickness of the elbow.
