Definitions

  • the present invention relates to a sealing strip adapted for sealing the longitudinal intervals between two parallel boards or planks, and in particular for sealing between planks or boards in a terrace structure.
  • planks usually of pressure-impregnated type, are arranged across all supporting beams at suitable intervals.
  • the boards are to be allowed to move a little during extensions and contractions caused by change in humid ⁇ ity, and the boards should also be allowed to move a little during changing load and temperature conditions.
  • the boards are arranged at intervals to allow water and snow to find a discharge possibility to avoid puddles forming in the middle of the terrace, which would lead to an accelerated decomposition of the materials in the terrace boards.
  • a further problem with existing terrace structures is that the boards will curve concavely upwards so that nails and other fastening devices are forced up from the boards when they move during changes in humidity and load condi- tions.
  • German patent No. DE 102.394 relates to a sealing bar adapted for use in connection with completely compact floors within buildings.
  • the shown sealing element is apparently completely stiff and is penetrated by openings for fastening screws. Therefore an element according to this patent would not prevent leaking if used out of doors.
  • U.K. patent No. 1.311.487 relates to a sealing element which also is designed to obtain a tight seal between floor ⁇ boards.
  • this element is made in two parts, each consisting of one hard portion and one soft portion. Such an element would not give any durable sealing between terrace boards used out of doors and exposed to high temperatures, very low temperatures, and long-lasting precipitation.
  • Swedish published application No. 462.809 relates to a stiff tightening bar which in fact allows the adjacent planks to be broken along pre-manufactured weakening sections in the boards. Therefore, it seems impossible to obtain a guite impermeable sealing when the boards afterwards contract, for instance during a dry period.
  • the sealing strip according to the present invention is in particular developed to be used together with pressure impregnated wood. Therefore, the sealing strip is designed in such a manner that contracting of the wood material enhan ⁇ ces the sealing effect of the sealing strip as barbed sec- tions are forced into the wooden boards during the contrac ⁇ ting process.
  • the sealing strip is, according to a prefer ⁇ red embodiment, shaped in such a manner that when the wood material expands the strip will be squeezed and deformed in such a manner that the side edge of said strip will be comp ⁇ ressed harder into the wood material the more the wood mate ⁇ rial expands. Due to these two features a complete tighte ⁇ ning will be obtained during all conditions.
  • the sealing strip according to the present invention also results in minimal curving of the boards.
  • the object of the present invention is to provide a sealing strip adapted for use between terrace boards in such a manner that all the disadvantages mentioned above are avoided.
  • the objects are to provide a water ⁇ tight and flat terrace of wood and in particular of impreg ⁇ nated wood in a simple and inexpensive manner.
  • Fig. 1 shows a sealing strip according to the present invention mounted between two terrace boards having milled out grooves
  • Fig. 2 shows in more detail a sealing strip of the type shown in fig. 1
  • Fig. 3 shows a sealing strip of a somewhat different em ⁇ bodiment
  • Fig. 4 shows a sealing strip of a still further embodi ⁇ ment, however also in accordance with the present invention
  • Fig. 5 shows an auxiliary fitting for transportation of water away from terraces of the above described type.
  • FIG. 1 shows a portion of a terrace 1 made of parallel boards 2 of which only two parallel boards are shown on the figure.
  • the boards shown are provided with inclined grooves 4,5 having such a design that when two boards 2 are posi ⁇ tioned alongside each other the two grooves 4,5 represent symetrical recesses at the same level in the two adjacent boards 2.
  • a pre-manufactured strip 8 is shown introduced in the interval 6 between the two boards 2 in such a manner that the side edges 3 of said strip 8 are forced into the grooves 4,5 in the adjacent boards 2 while a channel-shaped portion 15, in the middle of said strip or fitting 8, defines a downward curved flow channel between the two boards.
  • the strip 8 preferrably has approximately the same length as the boards 2, and therefore extends without interruptions from one end of the board to the opposite.
  • the complete terrace preferrably may be erected in such a manner that it is inclined somewhat in one direction or to both directions. Such a construction will account for a natural flow away from the terrace. It should also be mentioned that neither light nor water will flow in under the terrace, and due to this fact the ground below the terrace receives neither water nor light and therefore the growth of weeds below the terrace is strongly reduced.
  • Fig. 2 the cross section of the sealing strip 8 is shown in more detail. It is deemed to be very advantageous to provide the strip or fitting 8 with an acute angled break along its logi- tudinal side edges 3 which are folded sharply so that the strip 8 obtains a portion of an acute angle ⁇ , preferrably approximately 15°, along both side edges.
  • the folded portion of the side edge, on the figure extending from reference 3 to reference 14, has a width which slightly exceeds the width of the grooves 4,5. This will lead to a number of advantages mentioned below.
  • the outer, sharp edges along the outer side edges 3 of the strip 8 will act as barbs which may easily be pushed from the side into the grooves 4,5, but cannot be pulled out without taking special precautions.
  • the folded edge has such a dimension that it must be forced into the corresponding groove 4,5. According to this the side edges 3 will not be pulled out from the corresponding grooves 4 and 5 when the terrace boards 2 contract, for instance because they are getting dry.
  • the folded edge 14 will instead be subjected to a force which results in a minor extension of the angle ⁇ while the side edge 3 is forced still more tightly and closely to the inner surface of the grooves 4 and 5.
  • the strip 8 will be deformed at the bottom of the channel 15.
  • the elasticity of the strip will here allow the profile to open somewhat, so that the boards 2 may move a little from each other while the channel 15 in fact is more thoroughly tightened along its upper brim.
  • the sealing strip 8 may preferrably be designed exactly as shown in Fig. 2. It is then seen that the angle ⁇ 15° is repeated many places in the cross-section.
  • the outer folded brim has an angle a related to the adjacent flat area of the protrusion 9,10.
  • the side walls in the channel 15 also in turn make an angle ⁇ related to the vertical plane. Further the bottom of the channel 15 makes an angle ⁇ related to the horizontal plane.
  • the boards will be retained at a mutual distance 18 when outer stress does not occur.
  • this distance may be reduced to the width 19 at the bottom of the channel 15.
  • this bottom has a curved portion as shown 20, the distance between the boards may be reduced still further.
  • the dis ⁇ tance between the boards may also increase to exceed the distance 18 when the boards 2 contract. All the time the elastic strip will follow the movements and seal tightly to the adjacent boards without making any gap. Water falling down on the terrace will flow away along all the channels 15.
  • the cross- section of the strip 8 may be used for the cross- section of the strip 8.
  • the bottom of the channel 15 may be flat or wave-shaped, the side edges 3 may be folded downwards instead of upwards.
  • the strip 8 may be extruded having one portion folded upwards at 3 and one portion downwards at 3'and some of the folding lines as 17 and/or 20 may be completely omit- ted.
  • any bending and movement of the strip 8 will result in a better sealing against the encompassing wood.
  • This may be best understood if the situa ⁇ tion without such a folded or sharply bent edge 3 is consid- ered.
  • a movement of the boards relative to each other will make the protrusion on the strip 8 to move out of the grooves 4,5 which results in poor sealing, which in turn will make water flow out above the channel of the strip and contact the wood in the grooves 4 and 5 and thereafter also the under side of the boards 2.
  • a folded side edge 3 shaped to be forced into the groove 4,5 in the terrace boards 2 this situation will be avoided in all loading conditions.
  • a channel shaped por- tion 15 having a substantially rectangular cross section as assumed in Fig. 1 and 2 is deemed to be the best embodiment. This shape will give good flow conditions and it will also give the strip a great sideways flexibility when the boards are loaded in such a manner that they will move away from each other.
  • the shown cross section design of the strip 8 therefore will give a very high freedom of relative movement even if the strip fastens at both folded brims 3 in the material of the board 2. It is preferred that channel 15 is somewhat more narrow near its bottom than in its upper parts, as such a design will enhance the effects described above.
  • the sealing strip according to this invention is advantageous as such a strip represents a very useful remedy when terraces are to be built, as it secures a constant distance between all of the terrace boards along their complete length.
  • a terrace built by means of such channel-shaped fittings there ⁇ fore will obtain a better aesthetic appearance than a terrace built without such fittings.
  • such a seal may also be provided on already existing terraces which initially were built without such sealing strips. Then a profile mill may be guided in between two adjacent boards and guidedalong these boards while grooves are milled out in both board edges at the same time. When such grooves are milled out a strip may be pushed down into the gap from above. Due to the intrinsic elasticity of the strip, the sealing strip will expand when pressed down and a correct position in said milled out grooves will be obtained.
  • Fig. 3 shows a strip having a wavey bottom
  • Fig. 4 illustrates a strip with an evenly tilting bottom. Still further cross-sections may be provided within the scope of the present invention.
  • the strip may for ins ⁇ tance be flat along its complete width, as also such a design will allow some sideways movement between the terrace boards, in particular when the channel 15 is wider at its top than at its bottom.
  • the terrace may be finished according to the design shown in Fig. 5.
  • an end fitting 16 leads the flow of water to the edge of the terrace.
  • an end duct 16 arranged across of all the sealing strips 8.
  • the fitting or strip according to the present invention may be made from different materials.
  • One possible and suitable material is an iron plate having a protection of plastic, possibly with structured surface, and being for instance 0-5 mm thick. Galvanized metal plates 0.5 - 1 mm thick are also well suited. Still further materials may be plastic materials and laminates. Extruded strips of low weight metal, for instance aluminium, may also be used. It is preferred that the material has an even surface which may easily be cleaned, and it should preferrably be chosen from among materials enduring the required stress and temperature loads which are usual in buildings. Similarly the elasticity of the strip is important, as it should press back towards the grooves 4,5 when mounted.
  • the grooves which are made in the side edges of the terrace boards may also have different designs.
  • the grooves may for instance be tilted upwards as shown on the examples or they may be arranged horizontally.
  • the grooves may also have a less deep and more open shape. Combinations of the different shown shapes of said grooves and said strips may also be used without diverting from the scope of said inven ⁇ tion.
  • More than one single groove 4,5 may also be arranged in each board 2. In such cicumstances the strip 8 may be pro ⁇ vided with more that one protrusion 9,10 on each side.
