Definitions

  • the present invention concerns a structural element for buildings in accordance with the claims.
  • a yet further problem with existing designs of walls in buildings is that they do not include the possibility of controlling the amount of heat in the wall. This is especially significant in warmer climates. It is therefore costly to cool buildings.
  • a further problem with existing building structures is that it is difficult to monitor if there is a risk of moisture damage in the walls, floors, ceilings and the like. Normally, moisture damage will not be recognized until significant damage has already incurred in the building. Moisture damage leads to other consequential damages incurring in the building such as mold (mildew) and the like.
  • mold mold
  • log-like structural element which includes an insulating core
  • This log-like structural element includes an insulating core that consists of an insulating material.
  • the insulating material is on its one side provided with at least one material layer and its second opposite side (of the first side) is provided with at least one second material layer.
  • This design meets its intended purposes, but has the flaw that its insulating core is made of petroleum-based raw materials, that is to say, made of non-renewable resources.
  • the insulating core does not include elongated channels in accordance with the present design and this is why the design can not be used in a similar way as the present design.
  • the main purpose of the design according to the present invention is to create a substantially improved structural element for buildings.
  • Another purpose of the present invention in an alternative embodiment, is to create a log-like structural element, which shrinks to a much lesser extent than an ordinary log.
  • a further purpose of the present invention is to create a structural element which has a significantly improved sound-dampening capacity than existing logs.
  • a further purpose of the present invention is, in an alternative embodiment, to create a building element in the form of a sheet (panel, board) which can be used in floors.

  • the flanges 13 are given at least one thickness.
  • the channels 12 are given an extension length in depth from the core element's (piece of wood) first main side 8 toward its second main side 9 and given a depth which preferably amounts to more than half the distance between the first main side 8 and the second main side 9 and less than the distance between the first main side 8 and the second main side 9.
  • the core element's 7 first main side 8 includes a first set of channels 12 with intermediate flanges 13.
  • the flanges 13 are given at least one thickness.

  • FIG 4 is shown another conceivable variant of the core element 7 which has a third side 10 provided with at least one longitudinal channel 16. It is also conceivable that the fourth side 11 is provided with at least one longitudinal channel 17.
  • channels 12, 13, 16 and 17 as well as the core element's 7 dimensions may vary considerably within the scope of the present invention.
  • the channels' and the flanges' respective width as well as their thickness are dimensioned according to the requirements placed on a structure's load bearing capacity and other parameters.
  • the core 2 is made up of several core elements 7 which are joined flange against flange (such as is shown in the figures). By joining flange against flange longitudinal channels are formed in the structural element. The joining of flange against flange is accomplished by gluing or other for the purpose suitable joining method.
  • figure 5 is shown an example of an embodiment of the present invention, where it includes at least one first insulating core 2 and at least one second insulating core 18. The first insulating core 2 and the second insulating core 18 are preferably separated by at least one material layer 19.
  • the first insulating core 2 and the second insulating core 18 include in the exemplified embodiment a first core element 7, a second core element 20, a third core element 21, a fourth core element 22, a fifth core element 23 and a sixth core element 24.
  • the design may include several more core elements than shown in the figures.
  • the structural element 1 is essentially elongated.
  • the structural element 1 in accordance with the first embodiment is intended to be used as a log or similar.
  • Figures 5 A - 5C exemplify the use of the structural element 1, in the embodiment that is similar to a log.
  • the figures show how a first longitudinal structural element can be connected together to form a tie (corner) 26 together with a second structural element.
  • they are in their ends, or in their ends' proximity, provided with at least one notch (recess) 27 with which a unifying tie between at least one first structural element and one second structural element is created.

  • a tie 26 can be created between at least a first elongated structural element and a second elongated structural element and as such included in a first wall and a second wall. What is unique with the present tie is that it does not build in height (that is to say in the vertical direction).
  • the structural elements may even be provided with at least one protruding segment (not shown in the figures) which may for example be used at the tie or with the connection of several structural elements on one another in the vertical direction.
  • at least one protruding segment not shown in the figures
  • the number of notches may be more numerous or less and be of another for the purpose suitable form.
  • the first material layer 4 and the second material layer 6 are displaced in relation to the core 2.
  • the displacement is in the horizontal direction.
  • the core elements will dry substantially faster than existing logs dry thanks to the channels in the core elements as well as the intermediate flanges in the core elements.
  • the core element will preferably dry before the core (comprised of several core elements) is assembled (glued together). Thanks to each respective core element being dried before assembly, the core will essentially have finished shrinking before it is assembled. When using the structural element as a log, the problems caused by shrinkage in common logs will thereby essentially be eliminated.
  • FIG 6A and in figure 6B is shown an alternative embodiment intended to be used for example in a floor frame work. Size and thickness of the sheet-formed structural element may vary greatly within the scope of the present patent application.
  • the present structural element may be sheet-shaped (panel-shaped).
  • the core 2 on its top side is provided with at least one first material layer 4 and on its bottom side is provided with at least one second material layer 6.
  • the channels 12 and 14 are preferably placed in the transverse direction in relation to material layer 4 and material layer 6.
  • Figure 6B shows a structural element that can include at least one second core 18 with at least one second intermediate material layer.
  • the structural element includes elongated channels.
  • the elongated channels have resulted in the above stated technical effect that a flow of air through the channels can occur.
  • at least one fan can induce a stream of air to flow through the channels.
  • This design allows for the channels to be used for both cooling and heating the wall.
  • Relative cooler outdoor air can for example be used at night to cool the wall, which can be accomplished by the relative cooler outdoor air being conveyed into the walls (structural elements) elongated channels (channel 12 and channel 14).
  • the channels in several structural elements are intended to be connected with one another.
  • a wall's temperature can be reduced at night by using this method. This reduction of a wall's temperature at night can be utilized to cool a room during parts of the day. It is further conceivable that the opposite effect can be achieved, that is to say that the wall can be warmed during the day so it can radiate warmth at night. This is made possible since the structural element includes elongated channels through which a stream of relative cooler or relative warmer air can flow.
  • This flow is created by at least one fan emitting a flow of air channeled into channel 12 and channel 14.
  • the fan's emitted air can be supplied from outdoor air.
  • the emitted air may even be temperature conditioned with an AC system or similar temperature conditioning device.
  • a dehumidifier in accordance with earlier known technology, can be hooked up to dehumidify the air that is brought into channel 12 and channel 14.
  • the channels may be used to monitor moisture levels in a wall, floor frame work or similar. Moisture may for example derive from leakages in a water pipes or the like. Monitoring may be accomplished by a stream of air flowing through the channels, which is created for example by at least one fan.
  • At least one sensor is put in a place along the channels length that is suitable for the purpose.
  • the sensor consists preferably of a moisture sensor that detects the level of moisture and changes in the moisture level in the airflow. Detection of changes in moisture levels in the air flowing through the channels may be accomplished by use of at least two sensors. The moisture level of the incoming air into the structural element is measured and then compared with the moisture level in the air flowing out from the channels 12 and 14 in the structural element. If the moisture level rises above a predetermined level an alarm is set off.
  • the sensors can transmit information wirelessly or with wires to a monitoring system for moisture, mold or similar.
  • channels 12 and 14 are connected between several structural elements (enclosed elongated channels that run on from one structural element to at least one other structural element and preferably to several structural elements), the detection of moisture, the presence of mold and the like may be accomplished by one or two sensors for several structural elements. This is also applicable in combination with the earlier mentioned cooling and heating of the introduced air.
  • An unexpected technical effect has arisen during the impregnation of the insulating core 2. It has been shown that the present design allows for the complete saturation and thereby total impregnation (100 %) of all the wood material in the present insulating core 2.
  • the present invention may be impregnated by different kinds of impregnation agents that for example retard fire, protect against rot, mold and/or insect damage or similar.
  • a complete and total impregnation of all wood material in the insulating core 2 is made possible by the present invention's unique design. Complete and total impregnation (100 %) of all wood material in the insulating core 2 is achieved with current known impregnation techniques and this is why the impregnation procedure is not discussed further in this patent application.
  • the present invention is a method for use of the present structural element. It is also conceivable that at least one of the third sides and the fourth sides are provided with at least one material layer.
  • the present invention has a number of advantages. The most obvious is that structural elements are obtained, which liken a log, but shrink less than existing logs. Another advantage of the present invention is that a structural element which substantially eliminates thermal bridges is obtained. A still further advantage of the present invention is that a sound- dampening structural element is obtained. A yet further advantage of the present invention is that it allows for economical cooling and heating of walls.
  • the unexpected technical effect of complete and total (100 %) impregnation of the present invention, thanks to its unique design, is of great advantage in minimizing and even eliminating the risks of and damage of building structures from fire, insects, mold, rot and other similar negative effects.
