Cement fiberboard has a wide range of applications. Thin plates can be used for ceiling materials and can be perforated as sound-absorbing ceilings. Conventional boards can be used for walls and/or decorative materials. Thick boards can be used as LOFT steel floor boards, attic boards, exterior wall insulation boards, and wall covering boards. The following small series introduces the relevant knowledge of cement fiberboard construction technology.
Cement fiberboard construction process:
Construction tools: hand saws, electric circular saws, cutting knives, drills or cluster drills, hand plows or electric planers, nail guns, umbrella bolts, wall bolts, self-tapping bolts, wood screws, screws, injection screws, Hooks, flexible paper strips, sealants, foam strips, metal corners, metal trims, etc.
1. Dry construction method:
The first step: the application of large screws Lima screw, frame spring can be more than 0.8mm of fire-resistant galvanized aggregate.
The second step: 30cm -65mmx35mm column.
The third step: under 120cm - strengthen the crossbar.
The fourth step: the indoor construction plate joints need 3mm, outdoor need to stay 5mm.
The fifth step: the distance between the lock screw and the minimum distance is 1.5cm or more, 10cm spacing lock-screw.
2. Mixed construction method:
The first step: the application of large screws Lima screw, frame spring can be more than 1.0mm of fire-resistant galvanized aggregate
The second step: 40cm-65mmx35mm column
The third step: lock the screw from the margin at least 1.5cm or more, horizontal 10cm spacing lock a screw; from the top, the next row of screw distance 5cm, other 10cm.
The fourth step: The junction of the two plates cannot be continuous.
Step 5: Before the grouting is completed, the plate can be horizontally locked on the lateral side to strengthen the transverse column, and is to be removed after the grouting is completed.
3. External wall construction method:
A galvanized skeleton with a thickness of 1.2 mm or more and a spacer of 30 cm spacing. Firstly lock the layer of 12mm-15mm thick anti-sprague plate, then paste or lock the 8mm thick FOREX cement plate, and then do the surface waterproof paint treatment.
Seam processing: AB glue is not used to make up soil and screws to increase the strength of the wall to avoid cracking.
Cement fiberboard construction notes:
1. The wall can be divided into single-layer light steel keel double-side fixed fiber cement board and double-layer light steel keel double-sided fiber cement board. The staggered joints are fixed on the keel, and the middle is filled with rock wool or other insulation materials. House wall or compartment wall, that is, depending on the building sound insulation design requirements. The thickness of fiber cement board should be 8-10mm (inner wall), 12mm (outer wall) board, with light facing outward. Most of the foreign countries use the pressure strip method or open seam construction.
2, bathroom, bathroom and other places with high humidity, the board must be tiled, board surface hair outward. After the moisture content of the board to be confirmed is lower than 10%, seal the sealant on the board surface. After the glue is dry, paste the tile with AB glue. Never use cement mortar to prevent the fiber cement board from falling off.
3. The light steel keel frame of the fixed wall plate must be flat and stable, with reliable nail holding power.
4. When fixing the fiber cement board, it must start from the center of the board surface and gradually extend and fix it to the surrounding area, so as to avoid internal stress caused by improper fixing of the board surface, resulting in unevenness of the board surface as a whole.
5. When fixing the cement pressure plate with self-tapping screws, the nail pitch is 200mm for the ceiling plate, 300mm for the center of the wall plate, 200mm for the circumference, 13mm--15mm for the center of the nail hole from the center of the plate, and the nail head should be lower than the plate surface. 0.3mm.
6. After fixing each nail, apply a primer to the nail head immediately to prevent the nail head from rusting and affect the overall appearance.
7, in the fixed fiber cement board surface need to open the hole by slightly larger than the actual size of the line painted, such as the square hole, should be drilled in a hole in each square hole, aperture 10mm, and then portable marble saw Cut along the line. If it is a round hole, drill a hole in the inscribed circle, and then use a jig saw to cut along the line. Drill hole diameter is 10mm to remove the flash.
