Double-walled panel for building

Abstract

A double-walled panel for building includes a main body defining an inner space and two opposite open sides, and being internally provided with spacing boards to divide the inner space into a plurality of chambers respectively having two opposite open ends; a working liquid being filled in at least one of the chambers; and at least two sealing covers being respectively provided on one surface facing toward the main body with insert portions for sealing the two open ends of each of the chambers. The double-walled panel may be used as a ceiling panel or a partition wall. The working liquid filled in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in extinguishing fire when the building is on fire. The working liquid can also serve as drinking water for those who are trapped in a collapsed building during a disaster.

1 . A double-walled panel for building, comprising:
 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 being filled in at least one of 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; and the sealing covers being respectively 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.   
     
     
         2 . The double-walled panel for building as claimed in  claim 1 , wherein the main body is made of a plastic material. 
     
     
         3 . The double-walled panel for building as claimed in  claim 1 , wherein the working liquid is selected from the group consisting of water and other fire-extinguishing liquids. 
     
     
         4 . The double-walled panel for building as claimed in  claim 1 , wherein the working liquid filled in the chambers is in a volume smaller than or equal to a total volume of the chambers. 
     
     
         5 . The double-walled panel for building as claimed in  claim 1 , wherein the sealing covers respectively include a plurality of separated sections, and the insert portions being respectively provided on the sections on one surface thereof facing toward the main body.
