How is a suspended ceiling calculated?

It can be calculated according to the projected area, or it can be calculated according to the area. If it is a straight line reflective roof, it is calculated by area, and the area refers to the bottom surface plus (the size of the distance between the ceiling and the roof) and then multiplied by the total length to obtain the area of the ceiling, and the area of the ceiling is calculated.

In fact, it is to calculate the area of gypsum board, such as 20 square meters is 4 5, and the calculation method is 4 (square meters.

Design requirements for suspended ceilings:

1. It is used to shield structural components and various equipment, pipelines and devices.

2. For the ceiling of the room with acoustic requirements, its surface shape and material should be considered according to the sound quality requirements.

3. The ceiling is an important part of the interior decoration, which should be considered in combination with the interior design, and the various lamps and air conditioning outlets installed on the ceiling should become the organic whole of the ceiling decoration.

4. It should be convenient to maintain various devices and pipelines hidden in the ceiling.

5. The ceiling should be convenient for industrial construction, and avoid wet work as much as possible.

The ceiling is composed of decorative panels, keels, hanging wires and other materials, which can be changed according to the needs of the new material, according to the different materials of the decorative panels, the ceiling can be divided into gypsum board ceilings, metal ceilings, glass ceilings, PVC board ceilings, etc., gypsum board construction is relatively cheap, followed by PVC boards, metal plates are the most durable but the price is higher. The main use in home decoration is the aluminum gusset ceiling in the metal plate.

Suspended ceiling refers to a kind of decoration for the top decoration of the living environment of the house. To put it simply, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. The ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and is also a hidden layer for electrical, ventilation and air conditioning, communication and fire prevention, alarm pipeline equipment and other projects.

Ceiling area: (length + width) Ceiling width + (length + width) The height of the sag. The area around the ceiling:

(Inner perimeter + outer perimeter of the ceiling) 2 The distance between the inner edge and the outer edge is the area of the required materials, and the cost of the ceiling is generally calculated separately. If there is a light strip, the cost of the light strip needs to be calculated separately.

Calculation method: (length + width) 2 room height = wall area.

Length and width = top surface area (wall area + top surface area - door and window area) 35 = number of barrels used.

Taking the 5-liter capacity commonly used in households as an example, the theoretical coating area of 5 liters is 35 square meters for two passes.

Taking a room 5 meters long, 3 meters wide and high as an example, the interior wall and ceiling painting area is calculated as follows:

1. Wall area: (5 meters + 3 meters) 2 meters = square meters 2. Top surface area: (5 meters 3 meters) = 15 square meters.

3. Paint volume: (square meters = barrels.)

The building materials used in the top decoration generally include coatings, ceilings, top corners and lighting ceilings, and the packaging of paint latex paint is basically divided into two specifications: 5 liters and 15 liters.

Home improvement ceiling is a common link in home improvement. Suspended ceilings are classified differently according to the material of the decorative panel. Ceiling decoration materials are the main basis for distinguishing the name of the ceiling, mainly including:

Light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long aluminum gusset ceiling, square painted aluminum gusset ceiling, painted glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, whole house duplex ceiling, etc.

It occupies a very important position in the decoration of the whole room, and the appropriate decoration of the top surface of the room can not only beautify the indoor environment, but also create a colorful artistic image of the indoor space. When choosing ceiling decoration materials and design schemes, it is necessary to follow the principles of material saving, firmness, safety, beauty and practicality.

In general, like a 300*300 board, 11 sheets are almost a square, so it's easy to forget it.
