A SANDWICH PANEL WALL
FIELD OF THE INVENTION
The present invention relates to a sandwich panel wall, in particular to a joint between sandwich panel and a foundation. The invention further relates to a foundation fixing means and a joint between sandwich panels and a frame of building.
BACKGROUND OF THE INVENTION
Sandwich panels are conventionally used in construction applications, such as in warehouses, public buildings, business premises, and agricultural and industrial buildings. In these conventional applications sandwich panels often form the outer wall of building. Sandwich panels are commonly about 0,5-2 m wide and several meters long. Several sandwich panels are installed side by side to cover whole wall. Sandwich panels have one metal sheet as one surface and other metal sheet as other surface and an insulation material such as mineral wool or polyurethane between the metal sheets. Sandwich panels are often installed so that one surface of sandwich panel is outside the building and other surface is inside the building. Further in this document outer refers to an item which is outside of the building or near the surface which is outside the building. Further in this document inner refers to an item which is inside of the building or near the surface which is inside the building. Sandwich panels may be installed in vertical or horizontal direction. Usually sandwich panels are supported by the e.g. steel, wood or concrete frame of building which includes columns, beams and/or other type of girders. A sandwich panel wall is jointed to foundation usually by thin metal U- or L- profiles. The U- or L-profiles are fixed by screws or by other well-known fixing parts both to foundation and sandwich panel to fix the sandwich panel wall to the foundation.
An unexpected weather condition or an error during the installation of sandwich panels or rain during the installation of sandwich panels may cause rain water going into the sandwich panel wall. Water runs in a wall downwards and/or in horizontal direction and water ends up to the lowest possible point of wall which is usually U- or L- profile in the joint between the wall and a foundation. If the U-profile is made of continuous metal sheet, the water will stay long time between the flanges of U-profile which is harmful for the structure. If the joint comprise a thermal slotted U-profile or L-profiles, the leaked water may enter inside the building which is also harmful.
Continuous metal items like the web of U-profiles between the outer surface of wall and the inner surface of wall cause a heat bridge. Temperature on an inner surface near the heat bridge may drop down to the level that humidity in air condensates inside the building which is harmful.
In prior art rain water and/or condensation due to a heat bridge cause a risk of damages for a sandwich panel wall.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows the most preferable embodiment of a joint between a sandwich panel wall 1 and a foundation structure 2 according to the invention. This embodiment is easy to manufacture and same time it fulfills the improvements of this invention. In this embodiment a sandwich panel wall 1 is jointed to the foundation structure 2 by a foundation fixing means 7. In this embodiment a foundation fixing means 7 comprises an U-profile which further comprises an inner combined water barrier and fixing portion 8, an inner horizontal fixing portion 9, outer horizontal fixing portion 11, an outer vertical fixing portion 12, one or more holes in the lower side of outer vertical fixing portion 12 as a water passage 5 and slots 15 in the web of U- profile as a horizontal insulating portion 10. Preferably the material of U-profile is metal. Most preferable the material of U-profile is 0,5 mm - 4 mm steel. The slots 15 are in more than one queue between outer and inner horizontal fixing portions to prevent the heat bridge effect. The steel material between adjacent slots 15 forms a zig-zag figure. A fixing portion 8,9,11,12 comprises a solid material for screws or fixing parts to attach a sandwich panel wall 1 to a foundation structure 2. In this embodiment a foundation fixing means 7 comprises also a separate horizontal water barrier portion 6. Preferably there is no gap between the lowest point of a water passage 5 and the uppermost surface of horizontal portion to which a water passage 5 abutted on so all water runs out of the structure. The size of water passage 5 is preferably so large that water runs out of the structure despite of the surface tension of water. Preferably the size of water passage is more than 5x5 mm2 or 0 5 mm. Distance between neighboring water passages 5 is preferably 0,4 m-2 m. In this embodiment a horizontal water barrier portion 6 is over a horizontal thermal insulating portion 10. If a horizontal water barrier portion 6 would be under a horizontal thermal insulating portion 10, leaked water stayed in slots 15 which increase the drying time. Preferably in this embodiment there is no gap between a horizontal water barrier portion 6 and an inner vertical water barrier portion 8 so the drying is faster. Preferably the joint between an inner vertical water barrier portion 8 and a horizontal water barrier portion 6 is water tight. A water tight joint may be created e.g. by bonding a horizontal water barrier portion 6 and an inner vertical water barrier portion 8 together. Preferably in this embodiment there is a gap between a horizontal water barrier portion 6 and an outer vertical fixing portion 12. Water in the wall will run to above mentioned gap which fastens drying. All known water insulating materials with low thermal conductivity are suitable for a horizontal water barrier portion 6. Optionally the water insulation material has a corrugation which fastens drying. Preferably the water insulating material bonds by itself to a steel surface. One example of water insulating material is a butyl band.
Preferably in this embodiment a horizontal water barrier portion 6 has an inclination a which improves water to run out of structure through a water passage 5 because the outer edge of horizontal water barrier portion 6 is lower than the inner edge of horizontal water barrier portion 6. Inclination a is created by inclination of the top surface of foundation structure 2 or by material between a foundation structure 2 and a horizontal water barrier portion 6. An inclination a is preferably 1-15 degrees. A joint between a sandwich panel wall 1 and a foundation structure 2 according to this invention may comprise solutions which are used commonly in joint between a sandwich panel wall 1 and a foundation structure 2 like flashings 14, insulations 13,16 and joint means between sheet of sandwich panel 3,4 and a foundation fixing means 7.
Figure 2 shows one embodiment of a joint between a sandwich panel wall 1 and a foundation structure 2 according to the invention. In this embodiment a sandwich panel wall 1 is jointed to the foundation 2 by a foundation fixing means 7. In this embodiment a foundation fixing means 7 comprises one inner L-profile which further comprises an inner vertical fixing portion 8 and an inner horizontal fixing portion 9 and at least one outer L-profile which comprises an outer horizontal fixing portion 11 and an outer vertical fixing portion 12, a combined horizontal water barrier and thermal insulating portion 6, a vertical water barrier portion 22, one or more holes in the lower side of outer vertical fixing portion 12 or a gap between outer L-profiles as a water passage 5 and a gap between the fixing portions of an inner and an outer L-profiles 9,11. Preferably the material of L-profile is metal. Most preferably the material of L-profile is 0,5 mm - 4 mm steel. Preferably there is no gap between the lowest point of a water passage 5 and the uppermost surface of horizontal portion to which a water passage 5 abutted on so all water runs outside the wall.
The size of water passage is preferably so large that water runs out of the structure despite of the surface tension of water. Preferably the size of water passage is more than 5 mm, 5x5 mm2 or 0 5 mm. In this embodiment a combined horizontal water barrier and thermal insulating portion 6 is over an inner and outer horizontal fixing portion 9, 11. In some embodiments (not shown in picture) the top surface of a horizontal water barrier portion 6 is in same level than the top surfaces of horizontal fixing portions 9, 11. If a combined horizontal water barrier and thermal insulating portion 6 would be under an inner and outer horizontal fixing portion 9,11, some of the leaked water stayed in structure which increases the drying time. In this embodiment a combined horizontal water barrier and thermal insulating portion 6 and an inner vertical water barrier portion 22 are continuous material which is bended to L shape so there is no seam between an inner vertical water barrier portion 22 and a combined horizontal water barrier and thermal insulating portion 6 so all water goes out of the structure through a water passage 5. In this embodiment a gap a combined horizontal water barrier and thermal insulating portion 6 and an outer vertical fixing portion 12 is optional. All known water insulating materials with low thermal conductivity are suitable for a combined horizontal water barrier and thermal insulating portion 6 and an inner vertical water barrier portion 8. Preferably the water insulating material bonds to steel surface by itself. Optionally the water insulation material has a corrugation which fastens drying. One example of water insulating material is a butyl band.
Preferably in this embodiment a horizontal water barrier portion 6 has an inclination a which improves leaked water to run out of structure through a water passage 5 because the outer edge of horizontal water barrier portion 6 is lower than the inner edge of horizontal water barrier portion 6. Inclination a is created by inclination in a top surface of foundation structure 2 or by material between a foundation structure 2 and a horizontal water barrier portion 6. An inclination a is preferably 1 -15 degrees.
In this embodiment a joint between a sandwich panel wall 1 and a foundation structure 2 may comprise solutions which are used commonly in joint between a sandwich panel wall 1 and a foundation structure 2 like flashings, insulations and joint between sheet of sandwich panel 3,4 and a foundation fixing means 7.
In some embodiments joint between a sandwich panel wall 1 and foundation structure 2 comprises only inner L-profile (not shown in picture) but this kind of joint has less stiffness than joint with two L-profiles or one C-profile.
Figure 3 shows one preferable embodiment of wall corner according to the invention. In this embodiment an inner metal surface 4 of the sandwich panel wall 1 comprises a cutting between inner and outer metal surfaces 3, 4 of sandwich panel 19 to improve condensation preventing properties. A vertical fixing portion 7 may have accordingly comprises a cutting in the inner vertical fixing portion. Sandwich panels 1,19 are supported by a steel frame 18.
Figure 4 shows a preferable embodiment of joint of two sandwich panels to the column according to the invention. In this embodiment joint between sandwich panels 1,19 and column of frame 18 comprises a water tight material to prevent water leak to building. The water tight material is any kind of sealant such as e.g. silicon or polyurethane foam. In one preferable embodiment according to the invention the gap between outer metal surfaces 3 of sandwich panels 1, 19 are covered by a tape 21. Preferably the tape is material which allows drying outwards from structure but prevent water drops to enter the structure. Above mentioned material comprise e.g. so small channels that water vapor penetrates the material but water drops are not able to penetrate the material.
It is apparent to a person skilled in the art that as technology advanced, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
