Prefabric fiber reinforced cement (GRC) wallpanel

Abstract

The subject of the present invention relates to fiber reinforced cement (GRC) frontage panel heat isolated by foam concrete and a method for producing this. After putting steal stude frame which is secured to cassette by flexible anchorage, into GRC cassette which has 10 mm section width and formed by spraying GRC (Glassfiber reinforced Cement) to a mold in the form of panel, by filling cassette with foam concrete there is obtained heat isolated light, monoblock GRC outer frontage panel.

What is claimed is:  
     
         1 . The subject of the present invention is self heat isolated composite light wallpanel comprising FTB/GRC (glass fiber reinforced concrete), foamed concrete, special designed carrier steel stude frame (c) and steel wire mesh (g) having different characteristics, characterized in that the carrier steel stude frame (c) and the steel wire mesh (g) placed inside the heat isolated light wallpanel is totally covered with foam concrete and therefore does not constitute a heat bridge whereby the saturation on outer surfaces of panels caused by temperature differences is prevented.  
     
     
         2 . Self heat isolated GRC panel according to the preceding claims, characterized in that it comprises the following: GRC shell (b), omega sectioned steel stude frame (c), flexible anchorage rods (d), pads that connect flexible anchorage rods to shell inner face, foam concrete filling (f), foam concrete mounting steel wire mesh (g), anchorage plates (h) by which panel will be welded to four corners of the panel, diagonal profile (i) which is welded to anchorage plate.  
     
     
         3 . Self heat isolated GRC panel according to    claim 1    and    claim 2   , characterized in that the GRC shell (b) for the aim of providing heat isolation is filled with foam concrete before said GRC shell has set and during the same manufacturing process so that the light wallpanel is producted in one and same process.  
     
     
         4 . Self heat isolated GRC panel according to the preceding claims, characterized in that GRC shell (b) can be produced with requested form, design and shape and such that it can include every kind of detail such as window spaces, strip windows, blind frames, fringe, surface texture etc.  
     
     
         5 . Self heat isolated GRC panel according to the preceding claims, characterized in that steel stude frame (c) (FIG. 6) which is placed inside GRC shell (b), carries GRC shell (b) by means of flexible anchorage rods (d) and also provides panel to be fixed to building tablier (a) by means of diagonal profile (m) which is placed on anchorage plate (h).  
     
     
         6 . Self heat isolated GRC panel according to the preceding claims, characterized in that flexible anchorage rods (d) are placed on steel stude frame (c) with sufficient space.  
     
     
         7 . Self heat isolated GRC panel according to the preceding claims, characterized in that the steel stude frame is narrower to reduce the thermal transfer and that sufficiently thick foam concrete has been placed on both sides of the steel sude frame.  
     
     
         8 . Self heat isolated GRC panel according to the preceding claims, characterized in that flexible anchorage rods (d) are welded to steel stude frame (c) from one end and fixed to GRC shell from the other end and there is provided flexibility by means of the free 6-8 cm section (FIG. 5- c ) and as a result of this panel is not effected by ground and building movements.  
     
     
         9 . Self heat isolated GRC panel according to the preceding claims, characterized in that mounting of said panel to building tablier (a) is provided by fixing the diagonal profile (FIG. 2, 3 , 4 -L) which is fixed to anchorage plates (FIG. 6) on the corners of the panel, to steel strap on the building tablier (FIG. 2, 3 , 4 -J).  
     
     
         10 . Self heat isolated GRC panel according to the preceding claims, characterized in that it functions as mounting to foam concrete filing (f) and there is a layer of steel wire mesh (g) placed in steel stude frame (c) in order to prevent the possible cracks and openings on foam concrete.  
     
     
         11 . Self heat isolated GRC panel according to the preceding claims, characterized in that finished panel thickness is about 10-15 cm.  
     
     
         12 . Self heat isolated GRC panel according to the preceding claims, characterized in that finished panel weight is 80-100 kg for each meter square.  
     
     
         13 . A method for producing self heat isolated GRC panel according to the preceding claims, it comprises the steps of:  
 a) first panel mold made of steel or glass reinforced plastic is prepared with desired architectural form, design and detail;     b) 10-12 mm thick GRC shell (b) is formed by spraying GRC mortar into said panel;     c) steel stude frame (c) (FIG. 6) which is constructed so that it can receive wind load, particular weight and mechanic characteristics, is placed;     d) sufficiently spaced flexible anchorage rods (d) and anchorage plates (h) (FIG. 6- n ) which have  4  steel corners are provided over steel stude frame;     e) flexible anchorage rods (d) are padded to GRC shell by means of GRC mortar;     f) a layer of steel wire mesh (g) which functions as mounting to foam concrete filing (f) is placed on steel stude frame (c);     g) a panel is formed by filling foam concrete into GRC shell (b);     h) panel is sent to treatment chamber inside the mold;     i) after treating period panel is removed from the mold and becomes ready to transport to the construction area where it is going to be mounted.
