Description

Combined support hanger type ceiling and construction method

technical field

The invention relates to a combined support hanger-type suspended ceiling and a construction method, belonging to the field of house construction engineering.

Background technique

At present, with the rapid development of public building space, the decoration of large spaces has received great attention. Due to the continuous increase of equipment in the ceiling, the span of the ceiling space is getting larger and higher, and the height of the ceiling space is getting higher and higher. More and more, there are more and more technical problems of ceiling construction. When the ceiling is subjected to upward thrust or under the action of negative wind pressure, due to the excessive length of the suspending bars and insufficient rigidity, a certain bending deformation will occur, which will cause the entire ceiling system to deform upwardly or laterally, forming a "dome", which is easy to cause the ceiling. The system is unbalanced, causing uneven surface of the ceiling and even burying potential safety hazards.

The requirements of the current specification for large space ceilings: when the length of the boom is greater than 1.5m, anti-bracing should be set up, and there are no other design or construction requirements, which shows that the provisions of the specification are vague and general. The design unit is not familiar enough with the setting of the ceiling support. In the design, the setting of the ceiling support is unreasonable or conservative, there are large design defects, and there is no corresponding atlas for guidance, and the operability is not strong, resulting in the current ceiling The support settings are more confusing. There are also various problems in the current practice of large-space ceiling support. For example, when the support setting distance is too large or the support type is too small, it will cause large deformation of the ceiling, local instability, etc., resulting in deformation and cracking of the entire ceiling system. This will result in higher maintenance costs later on. If the spacing between the supports is too small, the construction operation area will be narrow, which is not conducive to the installation operation, delays the construction period, and the amount of steel is too large, resulting in a lot of waste.
