1. Characteristics of light steel keel partition wall <br><br><br><br><br><br><br><br> Light steel keel partition wall is a permanent wall. It is made of light steel keel as the skeleton and is made of paper-based gypsum board as the base material. The latex paint can be used on the face. The final decoration of various materials such as wallpapers, artificial materials, etc., is often used in the process of home decoration in the adjustment and design of space layout, such as the division of large indoor spaces, the modification and displacement of non-bearing walls. , Duplex residential building, such as the cover of the stairs. 2. Types of Light Steel Keels <br> The commonly used light steel keels are Q50, Q75 and Q100, which are suitable for different height partition walls. The family room height is generally within 3 meters, and the use of light steel keel of Q50 can meet the demand. Assembling the light steel keel skeleton requires the use of keels and corresponding fittings for different parts to be assembled into partition walls. 3. Types of gypsum plaster board <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> gypsum plasterboard From the performance point of view, there are three kinds of gypsum plaster board, fireproof gypsum board and waterproof gypsum board, which can be selected according to the needs of the environment. Dividing from the edge shape of the board, there are mainly two kinds of mold edges for dark seams and right-angle edges for clear seams or siding walls. The thickness of the gypsum board is 9mm, 9.5mm, 12mm, 15mm, 18mm, 25mm, etc. The specifications of the t-drywall are 2400mm, 2500mm, 2750mm, 3000mm, etc. The width of the board is 900mm. , 1200 mm and other specifications, so you can accurately choose the gypsum board according to the partition wall area and the position of the doors and windows. 4. Installation of Light Steel Dragon Skeletons <br> First, according to the design drawings, the position line of the wall body is popped up on the indoor floor, and the line is led to the side walls and the ceiling. The two lines should be ejected from the ground spring line, that is, the two walls. The projection line on the ground surface should be ejected. 5. Installation of plaster board <br><br><br><br><br><br> Light steel dragon skeleton is installed, after inspection is correct, you can install gypsum board, gypsum board should be arranged vertically, gypsum board on both sides of the keel should be staggered, with self-tapping Screws are fixed in order from the middle to the sides of the board. The distance from the board edge to the board is 10 to 16 mm. The board edge is at least 15 mm to the side of the cutting edge. The board side screw spacing is 250 mm. The distance is 300 mm. The nut is slightly embedded in the plate, but it must not damage the paper. The lower gypsum board should not be in direct contact with the ground. Leave a gap of 10-15 mm and seal it with sealant. 6. Installation of Light Steel Keel Shaped Partition Walls <br> One of the major advantages of the light steel keel wall is its ease of machining and installation of profiled wall surfaces. In home decoration, in order to make full use of space or increase the artistic effect of wall decoration, irregular wall surfaces are sometimes required. Now take the installation of the arc-shaped wall surface as an example to illustrate the installation method of the irregular wall surface. 7.Price analysis of light steel keel partition wall<br>Light steel keel wall is a kind of economical wall partition. The specifications of the keel are generally 3 meters long and have 75 mm, 100 mm and other width specifications. According to the keel material thickness and width, the price is different, each price is between 12-20 yuan. The price per standard sheet (2400 mm x 1200 mm) for plasterboard is between 22-30 yuan. With the cost of auxiliary materials and labor costs, the general decoration price of light steel keel partition wall is between 90-150 yuan per square meter, depending on the shape and material of the partition wall.

The light steel keel partition wall has the advantages of light weight, safety, strong impact resistance, non-toxicity and non-combustibility. It occupies less space in the interior and is convenient and quick to construct than other permanent wall materials. At the same time, it also has good sound insulation, heat insulation, anti-corrosion, anti-frog properties, can be used in any part of the family room, including kitchen, bathroom partition processing. It can also be used for high-grade sound insulation and thermal insulation to meet special environmental requirements. Therefore, the light steel keel partition wall is an ideal wall material.
Second, to do wall mats to ensure that the skeleton and the ground anastomosis. The specific approach is: first clear the ground contact, brush once again YJ302 interface agent, then hit the concrete wall pad, the top surface of the wall pad should be flat, both sides should be vertical.
Fixed along the ground, along the top keel, can be used to shoot nails or drilling with expansion bolts fixed, the spacing is generally 900 mm is appropriate, the shooting nail position should avoid the original base layer has been laid in the dark pipe.
The installation spacing of the vertical keel should be selected in accordance with the provisions of the height restrictions. When the dark seams are used, the spacing of the keel should be increased by 6 mm. If clear seams are used, the spacing of the keel is determined by the width of the clear seam. The walls of the wall where the objects need to be hung, the spacing of the keel should be shortened, generally 300 mm. The vertical keel should be arranged from one end of the wall. When the distance of the last keel from the wall is larger than the specified keel spacing, a keel must be added. The upper and lower ends of the vertical keel should be fixed with the kerf nails along the ground and along the top keel. When the keel needs to be cut at the scene, it shall be started from the upper end of the keel. Punching positions cannot be reversed and each keel is punched at the same level.
When installing the door pillars, they should be assembled according to the design of the door pillars. When installing the pillars, the door should be fixed together with the pillars. The installation method of the window is the same as the entrance.
When the height of the partition wall exceeds the length of the plasterboard or the wall has a window, a horizontal keel shall be provided. The connection method may adopt the manner of connecting along the ground, the keel along the top and the vertical keel, and the vertical keel may also be used. The angle bracket is connected to the vertical keel.
When installations such as switchboards, washbasins, and water tanks are required on the partition walls, the hangers of all types of wall-mounted equipment shall be connected to the skeleton of the dragon in advance when the skeleton is installed according to the design requirements.
After installing the gypsum board, clean the floating soil in the joints and use a putty knife to put the putty into the joint and level the board. After the putty in the seam is solidified, scrape lmm putty and paste the fiberglass seam tape. Use a putty knife to squeeze from the top. Press in the next direction, and scrape the surface so that the excess putty is squeezed out from the seam with the mesh. A putty knife was then used to scrape the putty on the entire surface of the decoration, and the seams were buried in putty. The edges of the gypsum board and the unevenness of the paper were all leveled, leaving the decoration of the surface to be finished.
When installing the curved wall surface, firstly draw the arc-shaped reference line on the ground and the ceiling respectively. This reference line should be double-lined. The drawing method is the same as the installation method of the general light steel keel partition wall. After cutting the notch along the ground and along the top keel, bend it to the desired arc shape so that the arc edge is tightly curved to the baseline. Use the nail to fix it on the ground and the ceiling. Use a self-tapping screw or hanging dowel for the vertical keel. Along with the ground, along the top keel firmly connected. The vertical keel spacing is determined based on the length of the arc. The principle is that each circular gypsum board should be applied to three vertical keels.
When installing the gypsum plasterboard, the back of the gypsum board should be equidistantly cut to a depth of 2-3 mm and a thickness of 2/5 of the thickness. The distance between cuts is determined by the radius of the arc. The smaller the radius, the smaller the cutting distance. When installing, the cutting surface* will be on the keel. From one side, the plasterboard is gradually bent so that it is close to the arc surface of the keel, and then used. Self-tapping screws secure it. Other installation steps are the same as general light steel keel plasterboard walls.
