Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a transparent building constructed using a translucent panel so as to allow external natural light to be taken in a high ceiling in a large building such as a building. The present invention relates to a light ceiling, and more particularly, to a light-transmitting lightweight ceiling that uses a non-combustible tent sheet for a ceiling panel and is configured to be easily maintained.

2. Description of the Related Art Conventionally, when building a high ceiling, such as a 50 m floor above a floor in a large building such as a building, as a translucent ceiling that receives external natural light, a translucent glass plate (mesh) is generally used. A glass plate) and a plastic plate (acrylic plate) are used as ceiling panels. In order to maintain the translucent ceiling, a self-propelled gondola is installed below the ceiling, or a catwalk is vertically and horizontally arranged above the ceiling.

Problems to be Solved by the Invention Conventionally, glass plates and plastic plates used as translucent ceiling panels are heavy and expensive, and are fragile and danger of falling even if they conform to interior restrictions. There are many problems.

In addition, as for the basement of the ceiling, it is necessary to have a native area that supports a heavy glass plate or a plastic plate. In addition, on the premise that the weight of the self-propelled gondola is loaded, the sectional size of the ceiling base material must be increased accordingly.
Then, the construction of the roof truss (or the ceiling beam) was greatly increased due to the recalculation of the structural calculations, and there was a problem that the cost was large and the economy was uneconomical.

In addition, the self-propelled gondola for maintenance is exposed under the ceiling, which greatly impairs the design and image of the translucent ceiling.

That being said, if the catwalk was laid vertically and horizontally above the ceiling instead of a self-propelled gondola, the shadow of the catwalk would be reflected on the translucent ceiling, so the design and image of the ceiling would be damaged, or only the shadow There is a problem that light transmittance is impaired, and these are problems to be solved.

Embodiment Next, the illustrated embodiment of the present invention will be described.

This lightweight ceiling, as evident in FIGS. 1 and 2,
The upwardly-opened channel 1 forms a grid-structured ceiling base consisting of a collection of squares of about 1300 mm on a side or a rectangle of approximately the same size, and has substantially the same shape and shape as one cell of this ceiling base. The large ceiling panel 4 is placed on each cell.

As shown in detail in FIG. 3, the channel member 1 forming the ceiling base is formed by bending an iron plate having a thickness of about 1.6 mm into a channel steel shape having a total width of about 130 mm. A hanging side 1b vertically connected to one side of the groove 1a is hung and supported by a hanging bolt 8 via a hanger 9, thereby forming a suspended ceiling. In particular, in the channel member 1, the ceiling base is formed by arranging parallel adjacent members in parallel in an arrangement in which the respective hanging sides 1b, 1b face each other. The two channel members 1, 1 arranged in parallel are joined by a connecting plate 15. Then, the flanges on both sides of the channel-shaped hanging tool 9 opening downward are connected to the hanging sides 1b, 1
It is superposed on the outside of b, and both are firmly fastened with bolts 16 and nuts 17. Approximately the center of the hanging tool 9 is the hanging bolt 8
Hanged at. The suspension bolts 8 are suspended from a beam or a roof frame, which is a ceiling frame of a building (not shown). A large number of the suspension bolts 8 are arranged at a pitch of about 1200 mm in the longitudinal direction of the channel 1.

The relationship between the building frame 18 around the ceiling and the base of the ceiling is such that the connecting member 20 is extended from the angle 19 attached to and fixed to the building frame 18, and this is joined to the channel member 1 so that the channel member 1 is fixed. I have.

The ceiling panel 4 has a structure in which a nonflammable tent sheet 3 is stretched in the plane of the panel frame 2 using an angle, as also shown in detail in FIG. External light is introduced through the tent sheet 3. On the lower surface side of the panel frame 2, a stopper (or anti-sway, the same applies hereinafter) 5 serving as a leg formed by bending a thin steel rod into an L shape is protruded (FIG. 3). It is configured to stand in one groove 1a. A handle 6 formed by bending a thin steel rod into a gate shape is installed at a substantially central portion of one side of the upper surface side of the panel frame 2.
