00 -2- "DOUBLE-WALLED PANEL FOR BUILDING" Field of the Invention The present invention relates to a panel for use in a building, and more particularly to a double-walled panel for building that not only helps in lowering 00 indoor temperature in normal use conditions, but also helps in putting out fire when the building is on fire.

00 Background of the Invention Generally, a conventional ceiling structure includes at least a set of lightweight steel frames connected to an inside roof of a room, and a plurality of plastic panels or gypsum panels is supported on the lightweight steel frames.

The plastic panels arnd the gypsum panels supported on the lightweight steel frames are only decorative panels without the function of lowering indoor temperature. Moreover, the plastic panels and the gypsum panels are easily burned and damaged in a fire to produce a large amount of black smoke and toxic gases, which increase people's difficulty in safely leaving the building on fire to result in increased number of injured and dead persons.

Summary of the Invention Throughout this specification and claims, unless the context requires otherise, the word "comprise" or variations such as "comprises" or "comnprising". will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of -any other integer or group of integers.

A primary object of the present invention is to provide a double-walled panel for use as a ceiling panel and/or a partition panel in a building, so that the panel not only helps in lowering indoor temperature in normal use conditions, but also helps in putting out fire when the building is on fire.

G 00 o -3- To achieve the above and other objects, the double-walled panel according to ;Z the present invention includes a double-walled main body defining an inner space and two opposite open sides, and being internally provided with a plurality of spacing boards to divide the inner space into a plurality of chambers, and each of the chambers having two opposite open ends at the two open sides of the main body; a working liquid stored in the chambers in the main body; and at 00 least two sealing covers for sealing the two open sides of the main body as well o as the two open ends of each of the chambers.

00 According to a preferred feature of the invention the main body is made of a ci 10 plastic material.

According to a preferred feature of the invention the working liquid is water.

Accord ing to a preferred feature of the invention each of the sealing covers is provided on one surface facing toward the main body with a plurality of insert portions for separately inserting into the open ends. of the chambers to seal the same.

According to a preferred feature of the invention the double-walled panel may be used as a ceiling panel or a partition panel.

The working liquid stored in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in pulling out fire when the building is on fire.

Brief Description of the Drawings The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the 2 5 accompanying drawings, wherein COMS ID No: ARCS-202765 Received by IP Australia: Time (1-tm) 18:54 Date 2008-08-19 19 Rug 2008 17:46 Wray Bunburj Fax 97914133 p.

Detailed Description of the Preferred Embodiments The embodiment of the invention is described with reference to Figs. 1 and 2 that are exploded and assembled perspective views, respectively, of a double-walled panel for building according to a preferred embodiment of the present invention, and Fig. 3 which is a sectional view taken along line A-A of Fig. 2. As shown, the double-walled panel of the present invention includes a main body 1, a working liquid 2, and at least two sealing covers 3.

The main body 1 is double-walled to define an inner space and two opposite open sides, and may be made of a plastic material. The double-walled main body 1 is internally provided with a plurality of spacing boards 11 to divide the inner space into a plurality of chambers 12, such that each of the chambers 12 has two opposite open ends 121, 122 at the two open sides of the main body 1.

The working liquid 2 is stored in the chambers 12 in the main body 1, and may be water or other suitable liquids.

The sealing covers 3 are connected to the two opposite open sides of the main body 1 to seal the open ends 121, 122 of all the chambers 12. Each of the sealing covers 3 is provided on one surface facing toward the main body I with a COMS ID No: ARCS-202765 Received by IP Australia: Time 18:54 Date 2008-08-19 19 Aug 2008 17:46 lxrayj Bunburyj Fax 97914133 p.

8 00 plurality of insert portions 31 for separately inserting into the open ends 121, 122 of the chambers 12 to seal the same.

Please refer to Fig. 4 that shows the installation of the double-walled panels of the present invention for use as ceiling panels in a building, and to Fig. 5 that is an enlarged sectional view of the circled area of Fig. 4. As shown, to use the 00 0 double-walled panels of the present invention as a ceiling panels, simply install Sthe already sealed main body 1 of the double-walled panels on a predetermined Sframework 4, such as a lightweight ceiling suspension system. Of course, the O double-walled panels of the present invention may also be used as interior C 10 partition panels.

The working liquid 2 in the sealed chambers 12 of the double-walled main body 1 provides the function of lowering indoor temperature when the environment in which the double-walled panel is used is in normal conditions. In the event the building using the double-walled panels is on fire, the working liquid 2 in the sealed chambers 12 of the main body 1 would be heated and vaporized due to the surrounding high temperature. The vaporized working liquid 2 results in expansion and final breaking of the plastic main body 1, so that the working liquid 2 in the chambers 12 of the main body 1 flows out of the damaged main body I onto burning things to help in extinguishing the fire.

With the working liquid 2 stored in the chambers 12, the double-walled panel for building according to the present invention not only helps in lowering indoor temperature in normal use conditions, but also helps in putting out fire, if the building is on fire unfortunately. Therefore, the present invention effectively overcomes the problems in the conventional plastic and gypsum panels and is very practical for use.

The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
