  • Detail

The ceiling refers to the top decoration of the living environment of the house. The ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption. It is also the hidden layer of electrical, ventilation and air conditioning, communication and fire prevention, alarm pipeline equipment and other projects. There are many materials for ceiling, such as common aluminum gusset board, gypsum board, sauna board, etc. today, let's take a look at asbestos board

asbestos board is the abbreviation of asbestos fiber cement plate, which is produced with asbestos, glass fiber, clay and other materials according to scientific formula. It has strong resistance to tension and pressure, and can withstand about 1400 ℃. It can be used for heat insulation, heat insulation and sound insulation, boiler, steel plant, chemical plant, aluminum plant and other general electrical insulation. What is the construction process of asbestos board ceiling

I. Introduction to asbestos board

asbestos board is the abbreviation of asbestos fiber cement plate. It is produced with asbestos, glass fiber, clay and other materials according to scientific formula. It has strong resistance to tension and pressure, and can withstand about 1400 ℃! It can be used for heat insulation, heat insulation and sound insulation, boiler, steel plant, chemical plant, aluminum plant and other general electrical insulation

the difference between asbestos board and mineral wool board: asbestos board is made of asbestos, adhesives and other materials It is suitable for heat preservation, heat insulation, sound insulation and electrical insulation. Mineral wool board is made of slag cotton as the main raw material, added with an appropriate amount of additives, after batching, molding, drying, cutting, surface finishing and spraying of mineral wool board. It does not contain asbestos, formaldehyde, heat preservation, sound insulation, moisture resistance, heat insulation and has good sound absorption function. Both materials can be used for decoration

II. The role of ceiling

1. Improve the indoor environment and meet the requirements of use functions

ceiling design should not only consider the requirements of indoor decorative effect and artistic style, but also consider the requirements of building use functions on building lighting, ventilation, heat preservation, heat insulation, sound absorption or reflection, sound, fire prevention and other technical performance, which directly affects the indoor environment and use. For example, the ceiling of the theater should comprehensively consider many problems in optical and acoustic design

2. Decoration of interior space

ceiling is an important part of interior decoration. In addition to the wall and ground, it is another large area surrounding the interior space. It plays an important role in rendering the environment and setting off the atmosphere in the room from the aspects of space, light and shadow, material, etc

III. construction process of asbestos board ceiling

1. Snap line: snap a 50cm control line according to the elevation led out from the elevation point in advance, and determine the standard line of the ceiling design elevation of each room according to the popped control line. Mark the grading control points of asbestos board on the wall, generally about 900-1200mm away

2. Installing hanging bars: determine the position of the hanging bars according to the requirements of the construction detail drawing, and brush antirust paint before installing the hanging bars. The diameter of the suspender is φ 6. The reinforcement shall be made and painted with anti rust paint, and the spacing between lifting points shall be 900-1200mm. During installation, the upper end is connected with the iron expansion bolt, and the lower end is connected with the hanger after threading. The exposed length of the installed boom end shall not be less than 3mm

3. Installation of keel: uc50 or u38 keel is adopted, and the spacing between ceiling keels is less than 1200mm. When installing the main keel, connect the main keel hanger to the main keel, tighten the screws, and arch the ceiling according to the design requirements. The arch height is about 1/20 of the short span, and the extension of the installed main keel should be staggered. Add lifting points at the joints, and check the flatness of the keel at any time. When the ventilation duct is larger than the maximum spacing requirement of the keel, angle steel of more than 30*3 must be used as the keel skeleton, and the skeleton cannot be in contact with the ventilation duct and other equipment works

4. Installation of asbestos board: according to the different installation methods and specifications of the panel, the secondary asbestos board is divided into T-shaped and C-shaped. The spacing of the asbestos board is 600mm. Hang the asbestos board on the large keel through the pendant, and install a 600mm transverse keel parallel to the main keel, with a spacing of 600mm or 1200mm. When shelving method and tongue and groove method are adopted for installation, the secondary keel is T-shaped, and C-shaped is selected for pasting method or other fixing methods

5. Installation of asbestos sheet and film: the specification and thickness of asbestos sheet and film are determined according to the design requirements. During installation, operators must wear white gloves to prevent pollution

Xiaobian conclusion: This is the Xiaobian's introduction to the relevant knowledge of asbestos ceiling, hoping to help you. For more relevant knowledge, please continue to pay attention to the information platform, and more wonderful content will be presented to you later
