Definitions

  • the invention relates to a building wall element according to claim 1 and a wood layer composite panel according to claim 12.
  • a well-known construction method for wooden houses is the block construction method.
  • the walls which are the supporting parts of the construction, are made of solid and horizontally superimposed beams.
  • the unavoidable drying or increase in wood moisture and the associated shrinkage and swelling of the wood are a problem because it can lead to subsidence or uplift.
  • the bars may warp or deform over time, so that they no longer lie sufficiently close together.
  • the warping of the beams leads to a leakage of the walls.
  • heat insulations are usually applied to the inside of the walls. Building physics brings this u.a. the disadvantage that the solid bars are arranged on the outside, so facing the cold side, whereby the heat storage of the wall is reduced.
  • the internal insulation arrangement adversely affects the position of the dew point in the wall. This is located behind the internal insulation in the wall, which leads to condensation (increase in moisture) in this area. Furthermore, additional wind seals increase the risk of condensation.
  • the DE 34 08 608 C2 describes a generic construction of a building wall element with an outer and an inner layer.
  • the individual beams of such beam layers are similarly stacked to each other as in a conventional log cabin wall.
  • the bars have a smaller thickness.
  • the two beam layers are arranged at a distance from each other.
  • Each post engages dovetailed in grooves that extend over the entire height of the bar layers.
  • the support consists of two parts, of which the first two grooves in the longitudinal direction initially only partially fills, and engages the second in the assembly movable part in the initially left free space of the grooves.
  • the construction of a wall in the manner described requires additional insulation material in the space between the layers, which is expensive and therefore undesirable.
  • the problem of warping is reduced due to the smaller cross-sectional dimensions of the beams, the problem of lifting and setting is not solved.
  • the EP 1 097 032 B1 describes a prefabricated Laminated wood element with at least three interconnected from immediately adjacent board or post-like woods, these woods have two different directions of two adjacent layers.
  • the plywood element is made of wood material and the connection of the individual layers is done by dowels, which enforce the layers of wood.
  • This construction essentially eliminates the setting problems known in log cabin construction. But to achieve good insulation properties and good wind resistance, the structure of a wall in the manner described must have a large dimension in the thickness direction of the woods or additional insulation material, which is expensive and therefore undesirable. In addition, the drilling of the holes and the insertion of the dowels is expensive.
  • the invention has for its object to provide a wall panel and a wooden panel that are dimensionally stable and can be easily and inexpensively manufactured.
  • this object is achieved with respect to the wall element by a building wall element with at least two layers juxtaposed woods having layers which are interconnected by means of opposing grooves and fixed ridge strips inserted therein, the wood fiber course of the wood runs parallel to the main load direction; and this object is achieved with respect to the wood panel by a laminated wood composite panel with at least two layers of juxtaposed layers of wood, which are interconnected by means of opposing grooves and ridge strips firmly inserted therein, the wood fiber profile of the woods is parallel to the planes of at least two layers and the Main load direction transverse to these planes.
  • the building wall element or the wood layer composite plate are constructed so that in each case adjacent woods have a plug connection with at least one extending over the length of the timber projection and are in mutual sealing engagement, wherein the end face of the respective projection is spaced from the respective opposite wood and a Expansion joint forms.
  • the connectors Through the connectors, a substantially tight connection between the woods of the respective layers can be created, which improves the heat and sound insulation.
  • the woods can still in their width direction shrinkage and swelling, without the overall dimensions of the building wall element or the wood layer composite panel are changed.
  • the expansion joint may also be an outwardly opening joint, in order to avoid any capillary action that may occur.
  • the ridge strips can penetrate into at least one sealingly engaging region of the plug connections in each case. This prevents air convection between the air spaces separated by the strips.
  • the ridge strips can be pressed by an increase in volume due to swelling against Nutbegrenzende surfaces of the grooves, so that a firm connection of the woods and the at least two layers is achieved.
  • a fixation of the woods and the at least two layers can also be achieved by connecting means which penetrate at least one side surface of the ridge rail and the woods.
  • fixation of the woods and the at least two layers can be achieved by gluing.
  • the aforementioned types of fixation can also be performed in combination.
  • the building wall element or the wood layer composite panel can be constructed of different types of wood within the same element. These types of wood can be used according to the desired requirements, without having to meet the otherwise required in timber construction symmetry requirements, which brings enormous benefits.
  • the woods of an outer layer may e.g. be constructed of a weather-resistant wood species, such as larch or oak, while the woods of an inner layer may be constructed of cheaper spruce wood.
  • the ridge strips could also be made of other wood, for example, made of very solid beech wood.
  • the building wall element may be at least one space between the at least two layers, the extent of which is between 0 cm and 5 cm in the thickness direction. This creates a thermally insulating static air layer. In the case of the laminated wood panel this gap can be up to approx. 50 cm.
  • Insulating material may be present in at least one space between two layers.
  • An angle between the groove and the wood grain course of the woods can be a right angle or can be from the right Deviate angle. By varying this angle, the stability of the building wall element or the wood layer composite panel can be adapted to the expected load conditions.
  • the laminated wood panel in a preferred embodiment consists of at least three layers.
  • a building wall element according to the embodiment of four layers of juxtaposed wood 2 having layers 1, which are interconnected by means of mutually opposite grooves 3 and strips 4 inserted therein.
  • the wood fiber profile of the wood 2 runs parallel to the main load direction, ie in the direction of the dead weight of the wall.
  • the strips 4 are ridge strips.
  • reference character A denotes a longitudinal direction of the woods 2
  • B a width direction of the woods 2
  • C a thickness direction of the woods.
  • the direction of the wood fiber course of the woods 2 corresponds to the longitudinal direction of the woods 2.
  • the reference numeral 6 denotes spaces between the layers 2.
  • the woods 2 have a plug connection 5 with over the length of the timber 2 extending projections 7, 9, wherein the woods 2 are in mutual sealing engagement, and wherein the end face of the respective projection 7, 9 is spaced from the respective opposite wood 2 and forms an expansion joint 11, as shown in Figures 1 to 3a.
  • FIG. 3 a shows that the timbers 2 each have two projections 7 and three recesses 8 at one of their side surfaces with respect to their width direction. On their other side surface, the woods 2 corresponding to three projections 9 and two recesses 10th
  • the projections 7, 9 are engaged with the corresponding recesses 8, 10, so that a tight connection is formed and an expansion joint 11 is present between the woods 2 with respect to their width direction. Thus, the woods 2 can expand toward this expansion joint 11 relative to each other.
  • the projections 7, 9 preferably each have the same dimensions.
  • the strips 4 each penetrate a sealing engagement area. This is indicated by a dashed line in Figures 3a and 3b. Thus, an air convection between the separated by the strips 4 spaces 6 is prevented, which improves the thermal insulation of the building wall element.
  • Figure 3b shows another embodiment of the connector 5.
  • only one projection 7 with a corresponding recess 10 is engaged, so that a tight connection is formed and an expansion joint 11 between the woods with respect to their width direction is present.
  • the woods 2 can expand toward this expansion joint 11 relative to each other.
  • the strips 4 penetrate here in each case in a sealing engagement area.
  • the connector 5 is not limited to the shape shown in Figures 3a and 3b, but can take any form that leads to a tight connection between the woods 2.
  • the woods 2 may each optionally have only one projection, two, three or more projections and the corresponding number of recesses.
  • the expansion joint may also be an outwardly opening groove to avoid any capillary action that may occur.
  • the arrangement of the above-mentioned groove 3 and the strip 4 is in the present embodiment parallel to the width direction of the woods 2.
  • the arrangement of the groove 3 and the bar 4 but can not be performed parallel to the width direction of the woods 2.
  • the strip 4 fixes the layers 1 and the woods 2 in two directions, ie in the thickness direction and in the longitudinal direction of the woods 2, as a result of positive locking.
  • the strip 4 and the groove 3 are dimensioned so that due to the change in volume, a non-positive connection between the woods 2 a layer 1 and the bar 4 is achieved.
  • the strip 4 according to the exemplary embodiment has two portions 4a, 4b that are tapered to one another, wherein the dimension of the side surfaces 4c, 4d in the longitudinal direction of the woods 2 is formed larger than a central region 4e.
  • FIGS. 4b and 4c show possible modifications of the strip 4.
  • a middle area 4f with respect to the thickness direction of the woods 2 is made larger than the middle area 4e from FIG. 4a. Consequently, the dimension of the ridge strip increases in the thickness direction of the woods. In this way, the gap 6 between the layers 1 in the thickness direction of the woods 2 can be increased.
  • a middle region 4g is made larger with respect to the thickness direction of the woods 2 than the middle region 4e from FIG. 4a and projects outwards in the longitudinal direction of the woods 2 in each case. In this way, both the form and the adhesion between the woods 2 a layer 1 and the strip 3 can be further improved.
  • a strip 4 is not limited to that shown in Figures 4a to 4c, but may take any shape that can be brought into engagement with a groove 3 in the manner of a ridge strip.
  • the ridge strips can also be made of a different material such as wood, for example of metal or plastic.
  • the fixation of the wood on the bar 4 by using dowels, nails, screws, glue, etc. can be achieved.
  • dowels, nails, screws, glue, etc. known system Connecting means
  • the fixation by means of volume enlargement and the fixation by means of system known connection means can also be performed in combination.
  • the layers 1 according to the exemplary embodiment are offset relative to one another, so that the tightness and the stability as well as the rigidity of the building wall element are further improved.
  • the layers 1 may not be arranged offset to one another.
  • the structural and physical properties of the building wall element can by the number of layers 1, the dimensions of the timber 2, the dimension of the interstices 6 between the layers 1, the execution of the connector 5, the arrangement of the layers 1 to each other and the choice of the wood desired requirements are adjusted as desired.
  • the symmetry conditions usually required in timber construction can be disregarded.
  • each wood 2 of a layer 1 can move in its thickness direction (direction C) and width direction (direction B) without changing the overall dimensions of the building wall element.
  • the well-known disadvantage of wood namely its directed change in volume, has added the structure of the invention no negative impact on the overall system. There is no subsidence and no warping, so that the tightness of the building wall element is maintained.
  • the invention can be applied not only to structures arranged substantially vertically or horizontally (e.g., walls and ceilings) but also to sloping constructions (e.g., roof structures).
  • the woods of a layer may be connected with respect to their widthwise direction by means of a plug connection (for example a groove-comb connection).
  • a plug connection for example a groove-comb connection.
  • the outer layer has plug connections, whereas the remaining layers have no connections.
  • the connector For low building physics requirement can be dispensed with the connector.
  • foreign materials such as insulating or sealing materials, can be incorporated between the woods of a layer.
  • connection of the woods of a layer is essentially by an increase in volume due to swelling of the strips used.
  • the number of strips used can vary as desired according to the desired requirements.
  • a fixation due to increase in volume of the strips is done by the moisture content of the strips is lowered below the moisture content of the woods and the dried strips are inserted into the opposite continuous grooves.
  • the dimensions of the strip and the groove are dimensioned so that a non-positive connection between the woods of a layer and the bar is achieved as a result of the volume change generated by the wood moisture balance.
  • the fixation of the layers in the longitudinal and the width direction of the wood is done by positive engagement with the strips.
  • a einstoffliches building wall element which can be referred to as Reinverbund.
  • connection means can be used if the moisture balance and thus the increase in volume of the bar has not yet taken place.
  • the groin may be subjected to a suitable treatment to increase the swelling effect.
  • the strip which is designed as a ridge strip, fixes the layers and the woods only in two directions, i. in the direction of strength and in the longitudinal direction of the woods. If the increase in volume of the strip is dispensed with, the fixing of the wood to the strip can be achieved by using other connecting means known per se. Of course, the fixation by means of volume enlargement and the fixation with the connecting means can also be carried out in combination.
  • a building wall element can be provided with space and without space between the layers.
  • the structure of the invention allows any number of layers and thus any number of air spaces.
  • a substantially static layer of air is created between the layers, which increases the thermal insulation of the component.
  • the distance between the layers forming this static air layer should be less than 5 cm in the building wall element in order to avoid air convection. For the laminated wood panel, this distance can be up to approx. 50 cm.

  • the outer areas of the round timber can be used in the building wall element as a ridge strip.
  • the timbers can be sawn or planed.
  • the outer surfaces of the woods are possible in visual quality.
  • the building wall element can only be made of wood (Reinverbund), good building physics properties result. For example, there may be no emissions caused by binding materials. Since the building wall element according to the invention furthermore requires no vapor barrier, etc., a moisture exchange can take place through the building wall element.
  • the layers of the building wall element according to the invention consist essentially of identical parts, that is, all woods can be the same and all ridge strips can be the same.
  • the rectilinear connectors and the grooves can be easily milled into the woods. Consequently, the building wall element can be easily machined with a large degree of automation is possible.
