Definitions
- the invention relates to a composite element made of wood and thermal insulation, in particular as a load-bearing wall element or as a roof or ceiling beam for House construction is used according to the preamble of independent claims 1 and 9.
- Load-bearing wooden cross-sections come primarily as supports / stems in the outer wall area of buildings that are erected in timber frame / frame construction.
- the currently used wood cross-sections or wooden handles are mostly beams made of solid wood, which at regular intervals in a house wall but also in the roof or Ceiling areas are arranged.
- the mentioned wood cross-sections because of their comparatively lower insulation value Thermal bridges that reduce the overall insulation value of the wall.
- the cross-sections are no longer from solid wood, but from two essentially parallel wooden slats in To form an I or box girder. Between or on the side of the two Wooden slats are arranged one or two thin wood-based panels, the two Connect the slats together (see Fig. 2). Immediately adjacent to each Carrier and / or insulating material is in turn arranged in the carrier itself. Through the Reduction of the wood cross-section in the central area of the beam is true Insulation effect compared to the solid wood beam improved, a thermal bridge remains but continue to exist in a reduced form due to the connecting wooden element.
- the composite element according to the invention essentially consists of at least two wooden slats arranged in parallel, between which - preferably exclusively - Insulation material is arranged and connected to the wooden slats.
- the insulation is selected so that an essentially rigid, one-piece composite element is formed that comes as close as possible to a cross-section of solid wood in its strength.
- Wood slats mean both slabs cut from solid wood, as well as slats, which mainly consist of wood and subsequently such slats are put together, for example glued laminated wood panels, single-layer fiberboard with directional fiber structure, in which the fiber direction preferably corresponds to the longitudinal direction of the slats and their fibers are longer than the largest cross-sectional extent of that viewed in the longitudinal direction Cross section of the slats.
- the wooden slats themselves can also be hollow chamber profiles be made of wood.
- the insulating material arranged between the wooden slats is preferably again in turn primarily from a wood material, in particular more than 90% by weight, in particular more than 95% by weight, in particular more than 98% by weight from one Wood material.
- the remaining constituents include, in particular, adhesive components and / or fire-retardant components, preferably as an adhesive Lignin-based adhesives can be used.
- Wood components in particular wood fibers, joined, in particular pressed or glued, materials in question, such as wood fiber boards, in particular the so-called soft fiberboard, which is a comparatively low have a specific weight and a high proportion of pores.
- the volume fraction of the pores in the insulation material should be at least 10%, preferably amount to at least 25%, the pores preferably being self-contained Pores are distributed evenly, as finely as possible over the Cross section of the insulation.
- the pores are preferably as small as possible, however, there are also large pore formations with a defined shape, for example in shape of through holes, recessed hollow bodies etc., conceivable.
- the insulating material arranged between the wooden slats alternatively consists of pressure-resistant Materials such as: polyurethane, polystyrene (extruded or expanded), Wood soft fiber MDF boards or mineral wool.
- the insulation used has a compressive strength of 20 kPa to 200 kPa, preferably the greatest possible compressive strength with the least possible compression and greatest possible heat-insulating effect, and in particular a compressive strength from 50kPa to 200kPa, especially from 100 - 200 kPa.
- the specific weight of the insulating material is between 15 kg / m 3 and 400 kg / m 3 , preferably 200 kg / m 3 to 400 kg / m 3 and in particular for rigid foams 20-60 kg / m 3 , mineral wool 60-200 kg / m 3 and soft fiber MDF boards 200-400 kg / m 3 .
- the thermal insulation effect of the insulation material is between 0.025 to 0.1 W / mK, preferably with numerical values as small as possible and in particular with 0.035-0.055 W / mK.
- the insulation material is preferably flush with the wooden slats on the side however, also be formed narrower if a material with sufficient compressive strength is used.
- the insulation is either foamed or by means of a suitable adhesive (or adhesive), e.g. PU glue, glued to the wooden slats.
- a suitable adhesive e.g. PU glue
- the insulation material can also be assembled Condition to be pressed.
- FIG. 1 shows a composite element 1 installed in a wall 4. Doing the composite element 1 approximately the wall thickness 4 without cladding / planking 5.
- the composite element comprises two wooden slats arranged essentially in parallel or square timbers 2, between which insulating material 3 is arranged.
- the wooden slats 2 are arranged on the outside, at the front and form 3 planes together with the insulation material side surfaces.
- the insulation 3 is firmly connected to the wooden slats 2, so that a substantially rigid, one-piece composite element 1 is formed.
- the wall 4 with an insulating material is directly adjacent to the composite element 1 6 completely or partially filled, which is usually from the material of the Insulating material 3 differs because the insulating material 6 in contrast to the insulating material 3 does not have to perform a supporting function.
- Fig. 2 shows a known I or box girder with two end faces arranged Wooden slats 2, between which in the case of the I-beam (left in Fig. 2) a wooden plate 7 is arranged with a smaller width.
- the box girder (right in Fig. 2) there are two Wood-based panels 7 arranged laterally on the wooden slats 2.
- the in between or laterally arranged wood-based panels 7 ensure stability and The column's load-bearing capacity, however, continues to form a thermal bridge, which is the total insulation value the wall reduced.
