What Is a Shed Roof?

The ceiling is also known as the "ceiling". Is an important building component of house construction. The function of the ceiling is to make the top of the house neat and beautiful, and it has the properties of heat insulation, heat insulation and sound insulation. General public places, such as theaters, conference rooms, entrance halls, business halls, etc., must be provided with ceilings. The ceiling is composed of a skeleton and a surface layer, and the skeleton is suspended by a keel (suspended ceiling joist) under a floor or a roof truss. The surface layer is divided into plaster and block. Plastering the ceiling is to nail wooden planks under the small keel. Then rub the lime hemp mortar surface on the wooden planks; the block ceiling is nailed to the small keel in two directions according to the size of the block, and then the block is nailed or pasted on the small square. The block surface layer includes fiberboard, plywood, sound-absorbing board, calcium plastic foam board and gypsum asbestos board. The block surface layer has the advantages of light weight, sound absorption, heat insulation, ventilation and easy installation. Calcium plastic foam board can be made into various relief patterns and with various colors, with a strong three-dimensional relief feeling. The disadvantage of the block surface layer is that it requires labor and materials, and the engineering cost is high. In industrial and civil residential buildings, it is usually used to directly apply the lime hemp mortar roof covering on the bottom of the floor. Disadvantages such as exposed ribs and inability to avoid pipeline installations. ^[1]

Also called ceiling, ceiling, flat roof, there are two types of ceilings commonly used: Luming ceiling, roof or

Sheds usually consist of a surface layer, a base layer and a boom.

1. Surface layer: The surface layer method can be divided into two types: on-site plastering (that is, wet operation) and prefabricated installation. On-site plastering is generally applied to mortars mixed with paper tendons, hemp, asbestos, or man-made fibers on gray slats and steel nets. Plastering has a large amount of labor, is prone to cracks, and even breaks down in pieces, which is suitable for small-area suspended ceilings. In addition to the prefabricated panels used for prefabricated installation, in addition to wood and bamboo panels, and various plywood, particleboard, fiberboard, sugarcane boards, and wood wool boards, there are various prefabricated boards.

1. Pay attention to the lightness of the ceiling shape. Briskness is the basic requirement for general interior ceiling decoration design. Up, down, and down are the foundation of the stability of the interior space composition. Therefore, the principle of ceiling form, color, texture, light and shade should be fully considered. Of course, the space required for special atmospheres is exceptional.

2. Meet structural and safety requirements. The decorative design of the ceiling should ensure the rationality and reliability of the structure and structural treatment of the decorative part to ensure the safety of use and avoid accidents.

3. Meet the requirements of equipment layout. Various equipments in the upper part of the ceiling are concentrated, especially in the complex design of high-grade, large-space ceiling ventilation and air conditioning, fire protection systems, and strong and weak electricity. At the same time, the relationship between vents, smoke detectors, automatic sprinklers, speakers and the ceiling surface should be coordinated.
