Description

Well ceiling structure {Structure of well type celing}

The present invention relates to a well ceiling structure, and more specifically, when installing a well ceiling formed on a ceiling slab of a building, the transmission path of the solid sound transmitted through the components such as the ceiling internal suspension and connecting members is minimized. In order to make the well ceiling structure by using the ceiling frame structure to connect and fix the ceiling plate and the ceiling plate of the well ceiling, it is possible to maximize the noise reduction effect on the floor impact sound while improving the workability and reducing the installation cost. It is about the ceiling structure.

In general, the ceiling of a building shields the upper slab structure, improves the aesthetics of the interior, and at the same time serves as a barrier to heat or reflection of noise, and a ceiling fixture for attaching a ceiling finish to the ceiling structure of a building. This is done by constructing and installing a ceiling finish.

The general structure of the ceiling frame for attaching such a ceiling finishing material is composed of a finishing material attaching member to which the ceiling finishing material is attached and a supporting member supporting it. As for the finishing material attaching member, a plurality of horizontal frames and vertical frames are horizontally aligned with each other. It is composed of a lattice-shaped frame structure that is cross-connected.

In particular, the well ceiling is an interior decoration recessed upward to install lighting equipment or ventilation equipment in the center of the ceiling, and is a ceiling finishing material that complements the interior of the interior by harmonizing with various lighting and ventilation equipment installed on the ceiling. It is a structure, and is manufactured in various shapes of design using a shape steel material, wood, or synthetic resin material.

These well ceilings are mainly used in construction sites that form the internal structure of modern buildings where the beauty of a design appealing to the aesthetic desires or sensibility of consumers is important, but the construction of well ceilings in the field is conventional ceiling surfaces. Various problems can occur compared to construction.

First, since the well ceiling structure must be fixed to the ceiling, the details such as the installation location and fixing method of the well ceiling must be designed and installed accurately, and after construction, additional post-processing or correction work may be required, and wood may be used. Therefore, when constructing a well ceiling, the construction time is prolonged due to the hassle of having to be installed in consideration of wiring to install an electric device such as a lighting fixture exposed from the ceiling. Back is generated.

In addition, during the construction process, safety accidents such as falling of the ceiling or attachments on the ceiling, etc., may occur.Therefore, there is a problem that requires great attention to construction, and the construction of the well ceiling in various sizes and designs There is a limit to doing, there is a problem that it is difficult to construct in accordance with the inclination of various consumers.

Moreover, in the case of a well ceiling, the use of components for installing ceiling finishing materials such as a ceiling frame, a sash, and a connecting member increases, so that the external sound such as interlayer noise is amplified due to an increase in the transmission path of solid sound transmitted through these components. There are potential problems.
