DOUBLE-WALLED PANEL FOR BUILDING
FIELD OF THE INVENTION
[0001] 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 indoor temperature in
normal use conditions, but also helps in putting out fire when
the building is on fire.
BACKGROUND OF THE INVENTION
[0002] 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.
[0003] The plastic panels and 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
[0004] A primary object of the present invention is to provide
a double-walledpanel 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.
[0005] To achieve the above and other objects, the double-walled
panel according to 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 least two sealing covers for sealing
the two open sides of the main body as well as the two open ends
of each of the chambers. The double-walled panel may be used
as a ceiling panel or a partition panel.
[0006] The working liquid stored in the chambers not only helps
in lowering indoor temperature in normal use conditions, but
also helps in putting out fire when the building is on fire.

[0007] 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 accompanying
drawings, wherein
[0008] Fig. 1 is an exploded perspective view of a double-walled
panel for building according to a preferred embodiment of the
present invention;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Please refer 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
3
CA 02639660 2008-09-19
present invention, and to Fig. 3 that 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.
[0014] 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.
[0015] The working liquid 2 is stored in the chambers 12 in the
main body 1, and may be water or other suitable liquids.
[0016] 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 1 with a plurality
of insert portions 31 for separately inserting into the open
ends 121, 122 of the chambers 12 to seal the same.
[0017] 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
4
CA 02639660 2008-09-19
sectional view of the circled area "a" of Fig. 4. As shown,
to use the double-walled panels of the present invention as a
ceiling panels, simply install the already sealed main body 1
of the double-walled panels on a predetermined framework 4, such
as a lightweight ceiling suspension system. Of course, the
double-walled panels of the present invention may also be used
as interior partition panels.
[0018] 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 1 onto burning things to help in
extinguishing the fire.
[0019] 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
CA 02639660 2008-09-19
effectively overcomes the problems in the conventional plastic
and gypsum panels and is very practical for use.
[0020] 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.
