Description

WALL MODULE AND BUILDING WITH SUCH A WALL MODULE
Technical field
The present invention relates to a wall module arranged to be used as at least a part of a wall in a building. More
specifically the invention relates to a wall module comprising an inside and an outside, at least two load bearing studs with an inside and an outside, at least one outer cover board arranged on the outside of the load bearing stud, at least one inner cover board arranged on the inside of the load bearing studs, which cover boards span over the space between the load bearing studs, and isolation arranged between the load bearing studs and between the cover boards .
Background of the invention Buildings with a load bearing frame of wood, so called wooden buildings, is one of the most common types of buildings.
Buildings may be single family houses or blocks of flats. The number of stories in a wooden building is usually not more than four. Wooden buildings may be built in a number of different ways. One alternative is to use so called loose timber, wherein the entire load bearing frame is assembled on the building site. Another alternative is to assemble the building by modules. The modules may either consist of walls or may be so called volume modules. The modules may have different degrees of finishing and may comprise finished surface layers on the inside as well as the outside.
In later years the interest for energy efficient buildings have increased dramatically. A large part of the energy which is consumed in a building is used for heating of the building. In order to minimize the energy consumption for heating it is necessary that walls and windows are well insulated so that they transfer small amounts of energy from the inside to the outside. The insulation capability may be measured with the so called K-value . In order to achieve a low K-value it is common to use thick glass wool insulation. Further, it is necessary to prevent unwanted air flow between the outside and the inside of the house as such leakage leads to energy losses. In order to minimize said leakage plastic is usually used on the inside and/or the outside of the insulation so that air may not pass through the wall.
However, it is difficult to achieve a low K-value over the entire extension of the wall as heat leaks out via the studs in the walls, which studs in principle extend through the entire thickness of the wall. Furthermore, it is difficult to fill the entire space between the studs with glass wool insulation .
The PCT application WO 91/02865 (Dl) describes an I-girder which is not only light in weight and dimensionally stable but also easy to manufacture. According to the invention, this object is fulfilled with a girder of the type which is mentioned in the beginning which comprises two wooden flanges connected with styrene plastic. Boards of plywood or another suitable material is arranged on both sides of the foam plastic and in contact with the wooden flanges.
US 4329827 (D2) describes roof elements which comprise two at a distance from each other arranged boards between which girders and mineral wool are arranged. The Swedish patent 413529 (D3) relates to buildings with a girder frame. In D3 I -girders are shown with two wooden flanges with a board material between them as a waist.
The German patent publication DE 199 57 080 Al (D4) describes girders which are constructed by an inner girder and an outer girder with mineral wool between them and which are arranged between two boards such as for example chip boards .
Summary of the invention
An object of the present invention is to provide a wall module and a building which at least partly solves the problems with the prior art .
Another object of the present invention is to provide a wall module and a building which is less complicated in its construction compared to wall modules and buildings according to the prior art.
Another object of the present invention is to provide a wall module and a building with better heat insulation than wall modules and buildings according to the prior art.
At least one of these objects is fulfilled with a wall module and a building according to the independent claims.
Further advantages with the invention are provided with the features of the dependent claims .
A wall module according to the invention is arranged to be used as at least a part of a wall in a building. The wall module comprises an inside and an outside, at least two load bearing studs with an inside and an outside, at least one outer cover board arranged on the outside of the load bearing studs, at least one inner cover board arranged on the inside of the load bearing studs, which cover boards span over the space between the load bearing studs, and insulation arranged between the load bearing studs and between the cover boards, wherein the inside is intended to be directed towards the inside of the building and the outside is intended to be directed towards the outside of the building. At least one of the load bearing studs comprises an inner beam, an outer beam, a block of cellular plastic arranged between and glued to the inner beam and the outer beam. The wall module is
characterized in that at least one of the load bearing studs comprises two beam boards which are arranged on each side of, spans over and are glued to the inner beam, the block of cellular plastic and the outer beam, and that the insulation is constituted by cellular plastic, wherein the insulation is glued to the surrounding studs and to the cover boards.
Preferably, the insulation is the same type of cellular plastic as in the blocks of cellular plastic between the inner and the outer beam. The beam boards are preferably of the same board material as the cover boards . Thereby the number of different components which are required to build the wall module is minimized.
The wall module according to the invention provides good heat insulation also at the studs due to the fact that they are constructed with a block of cellular plastic between an inner beam and an outer beam. Cellular plastic heat insulates considerably better than wood. With a wall module heat losses through uninsulated massive wooden studs are thus avoided. That also the insulation between the cover boards is of cellular plastic contributes positively to the heat insulation of the wall module. Furthermore, the cellular plastic is tight which means that moisture cannot penetrate through it. This contributes to the fact that the wall module may be built without a separate moisture barrier. Also the cover boards contribute to the fact that the moisture barrier may be avoided. The cover boards are preferably of a material that does not absorb moisture.
By the insulation being glued to the surrounding studs and to the cover boards air spaces between the cover boards are avoided which would result in uninsulated areas on the wall module . The insulation may be constituted by a material chosen among expanded polystyrene and extruded polystyrene. Said materials are cellular plastics which are well suited for use as
insulation. There are also other types of cellular plastics such as expanded polystyrene. The man skilled in the art may easily choose a suitable cellular plastic.
At least one of the cover boards and the beam boards are wooden fibre boards. Preferably the beam boards and the cover boards are of the same board material in order to facilitate the construction. At least one of the cover boards and the beam boards may be laminated wood boards . Laminated wood boards have better strength than pressed wood fiber boards but are more
expensive .
The cover boards and the beam boards preferably have a density which is at least 700 kg/m3. More preferred the cover boards and the beam boards have a density which is at least 900 kg/m3. By pressing the wood fibre boards under high pressure they become tight and get high density. This is preferable in that the boards then do not let through or absorb moisture. The insulation preferably has a thickness in the interval 150- 400 millimetres. With a cellular plastic with a thickness of 200 millimetres a thermal conductivity coefficient (U-value) of approximately 0.17 is achieved. The stud in at least one end of the wall module may be
intended to constitute a corner post in a building and be constituted by a massive wood post or steel post while the studs in the wall module comprises an inner beam, an outer beam, a block of cellular plastic arranged between an glued to the inner beam and the outer beam, and two beam boards which are arranged on each side of, spans over and are glued to the inner beam, the block of cellular plastic and the outer beam. With such a construction of the wall module a high strength in the corner of the building is achieved. As has been mentioned above, the insulation may preferably be glued to the surrounding studs and the cover boards in order to avoid air slits in the wall module. In order to further minimize the risk for air slits two adjacent studs on the sides of each piece of insulation may be pressed against the insulation using screws that run through the studs and the insulation .
According to a second aspect of the present invention a building is provided comprising at least one wall module comprising an inside and an outside, at least two load bearing studs with an inside and an outside, at least one outer cover board arranged on the outside of the load bearing studs, and at least one inner cover board arranged on the inside of the load bearing studs. The cover boards span over the space between the load bearing studs. The wall modules also comprise insulation arranged between the load bearing studs and between the cover boards. The inside is directed towards the inside of the building and the outside is directed towards the outside of the building. The building is characterized in that at least one of the load bearing studs comprises an inner beam, an outer beam, a block of cellular plastic arranged between and glued to the inner beam and the outer beam, and two beam boards which are arranged on each side of, spans over and are glued to the inner beam, the block of cellular plastic and the outer beam and that the insulation is constituted by cellular plastic . A building according to the second aspect of the present invention provides the same advantages as has been described above in relation to the first aspect of the invention. A building according to the invention may be built as a so called passive house more easily and less expensive than passive houses according to the prior art as there is no need for a separate moisture barrier and as air pockets and thermal bridges have been minimized. Thermal bridges in the form of massive wood pillars have been removed by the use of insulated studs. Air pockets may be eliminated as the insulation in the form of cellular plastic may be glued to the studs and to the cover boards .
Preferably, beams in at least one of the floor structure beams and the roof trusses are constituted by building beams
comprising an inner beam, an outer beam, a block of cellular plastic arranged between and glued to the inner beam and the outer beam, and two beam boards which are arranged on each side of, spans over and are glued to the inner beam, the block of cellular plastic and the outer beam.
Such a building may be produced in a rational way as the number of different components used may be kept low. In the following, embodiments of the invention will be
described with reference to the appended drawings.

Fig. 2 shows a wall module according to an embodiment of the present invention, which comprises building beams according to fig. 1.
Fig. 3 shows in cross section the building according to an embodiment of the present invention with wall modules
according to fig. 2.
Fig. 4 shows in larger detail in cross section a corner in a building with wall modules and beams according to fig. 2 and fig. 3. Description of preferred embodiments of the invention
In the following description of preferred embodiments similar features in the different drawings will be denoted with the same reference numeral. The figures are not drawn to scale.
Fig. 1 shows a building beam 1 which is used in a wall module according to an embodiment of the present invention. Fig. la shows the building beam in a view towards the longer side while fig. lb shows the building beam in a view towards the shorter side. Fig. lc shows the building beam in cross section along the cut AA. The building beam comprises a first inner beam 2 in the form of a wood list, a second outer beam 3 in the form of a wood list, and insulation in the form of a block 4 of cellular plastic. The block 4 of cellular plastic is arranged between and glued to the inner beam 2 and the outer beam 3. The first beam board 5 and a second beam board 6 are arranged on each side of, spans over and are glued to the inner beam 2, the block 4 of cellular plastic and the outer beam 3. Fig. 2 shows a wall module 7 according to an embodiment of the invention, which comprises building beams 1 according to fig. 1. Fig. 3 shows in cross section a building 8 according to an embodiment of the invention with wall modules 7 according to fig. 2. The wall module 7 is arranged to be used as at least a part of a wall in the building 8. The wall module 7 comprises an inside 9 and an outside 10 and a number of load bearing studs 11 with an inside and an outside, at least one outer cover board 12 arranged on the outside 10 of the load bearing studs 11 and at least one inner cover board 13 arranged on the inside 9 of the load bearing studs 11. The cover boards 12, 13, span over the space between the load bearing studs 11. Insulation 14 in the form of cellular plastic is arranged between the load bearing studs 11 and between the cover boards 12, 13. The insulation 14 is glued to the surrounding studs and to the cover boards 12, 13. The insulation 14 is
preferably constituted by a material chosen from expanded polystyrene and extruded polystyrene. As the insulation is glued to the studs and to the cover boards a good insulation is achieved over the entire surface of the wall module. The inside 9 of the wall modules 7 is thus intended to be directed towards the inside of the building 8 and the outside of the wall modules 7 is intended to be directed towards the outside of the building 8.
The cover boards 12, 13 and the beam boards 5, 6, are
preferably boards of the same sort such as wood fibre boards or cross veneer boards. The cover boards 12, 13, and the beam boards 5, 6 are preferably Masonite construction boards, or It- board which it is usually called. This is a technically and economically preferable alternative to wood or glued material in different kinds of building constructions. The K-board is manufactured from wood raw material with extra long fibres and pressed to a very high density of 940 kg/m3. This gives the board an extreme strength and toughness. It is of course possible within the scope of the invention to use other wood fibre boards than Masonite. It is however important to use wood fibre boards which have been pressed hard. Preferably the wood fibre boards which are used in the invention have a density of at least 700 kg/m3, and preferably at least 900 kg/m3. Such hard pressed wood fibre boards have a high strength if they are combined with long wood fibres. The studs 11 preferably have a cross section with a width of
20-100 millimeters and a depth of 100-300 millimeters. Typical measures on the cross section of the studs 11 is 60
millimeters wide and 200 millimeters deep. With width and depth is meant the short and the long measure, respectively, of the cross section of the stud 11. The height of the studs 11 is adapted to the desired room height in the building 8. The studs 11 are arranged in a wall module 7 so that the depth defines the distance between the cover boards 12, 13. The wall module 7 with cellular plastic as insulation 14 between the cover boards 12, 13, and with 200 millimeters depth have a heat transfer coefficient (U-value) of 0,17.
The stud 11 in at least one end of the wall module is intended to constitute corner post in a building 8 and is constituted by a massive wood post or steel post while the studs 11 in the wall module 7 in other respects are constructed according to the description above. In the building 8 essentially all beams 1 are of the type which has been described above. Thus, studs 11, roof trusses 15 and floor structures 16 are constructed with beams 1 according to fig. 1. As is evident from fig. 3, the beams 1 in the floor structure 16 are doubled and are arranged one on each side of a stud 11. Between the studs 11 and the cover boards 12, 13 there is arranged insulation 14 in the form of cellular plastic which is glued to the studs 11 and the cover boards 12, 13, and thereby completely fills the space between the studs 11 and between the cover boards 12, 13. Preferably the insulation 14 is cellular plastic. A way of avoiding the presence of any air slit between the insulation 14 and the studs 11 on both sides of the studs 11 is to arrange through screws 17 through two studs 11 and the intermediate insulation 14 so that the insulation is squeezed in place between the studs 11.
Fig. 4 shows in larger detail in cross section a corner in a building 8 with a first wall module 7 and a second wall module 7' and beams 1 in accordance with fig. 2 and fig. 3. The first wall module 7 has an outer cover board 12 which extends longer than the first wall module 7. On the inside of the wall module 7, 7', there is arranged inner boards 19 which are arranged at a distance from the inner cover boards 13. The space between the inner boards 19 and the inner cover boards 13 may be used to arrange hidden cables. The inner boards 19 may for example be gypsum boards which may serve as underlayer for painting and hanging of wall paper. By arranging inner boards 19 of gypsum the fire class of the building may also be raised.
The described embodiments may be amended in many ways without departing from the spirit and scope of the invention which is limited only by the appended claims. It is of course possible to arrange other types of boards than gypsum boards as inner boards in the bui lding .
