calcium silicate board has a wide range of applications. Ceiling and partition are two common methods. So how to construct and install calcium silicate board ceiling? What are the construction precautions for using calcium silicate board as partition wall? Next, let's answer it by Xiaobian.

1. How to construct and install the ceiling with calcium silicate board

1. To install the ceiling with calcium silicate board, firstly, it is necessary to play the thread, prepare the thread and dye, fix the position where the ceiling needs to be installed, and mark it with the thread. When playing the thread, it is necessary to consider the reserved position of the keel, and the general distance is between 911 mm and 1211 mm.

2. After the elastic thread is finished, you can prepare to install the hanger bar. The hanger bar needs to be installed according to the position of the installation drawing. Before installation, paint should be applied to the surface of the hanger bar to make its color more consistent and beautiful. The hanger bar is used for fixing the keel, so you must pay attention to and check its firmness during installation. After installing the hanger bar, install and fix the keel, and finally install the calcium silicate board ceiling on the keel.

Second, what are the construction precautions for using calcium silicate board as partition wall

1. When using double-layer calcium silicate board partition wall equipment, the fixing method of one layer of board is the same as that of single-layer calcium silicate board wall. However, the drawing seam of the second layer of calcium silicate board cannot fall on the same vertical keel with the first layer of seam.

2. The calcium silicate board equipment should be laid longitudinally to minimize horizontal joints. The edge of the plate should fall in the middle of the keel (the spacing of the keel should closely match the width of the plate).

3. For the calcium silicate board with ceramic tiles, the equipment method of the board is the same as that of the single-layer calcium silicate board wall, but in order to make the mortar bond with the board well, the smooth surface of the board needs to face the keel and the rough surface outward. Use 6mm thick 1:1 cement mortar to smear the calcium silicate board and 117 glue contact layer on the wool surface, and then bond 5mm thick ceramic tiles on the contact layer.

4. The plate and keel are fixed with 4 mm and 25 mm self-tapping screws, and the screws around the steel plate are blocked by 211mm in the middle and 311mm in the middle.

5. Because the overlap width between the panel and the main keel is small (about 21mm), the keel spacing specification should be accurate and vertical.

6. caulk the board joints with putty, then sew them with paper towels, scrape putty and polish them flat.

thus, it can be seen what the construction and installation requirements of calcium silicate board are in the application of suspended ceiling and partition wall.
