Definitions
- the invention concerns a method for the manufacture of wooden frame pieces for use in window frames and door frames, said frame pieces being provided with concealed channels in which impregnation agents can be introduced for the protection of the wood against dry-rot and mould fungus, and where the channels open out on the outer side of the frame for the filling of the agents, and also the use of the frame parts manufactured by the method.
- Wood has a long tradition as a building material, and it is used to an increasing degree where it can fulfil the requirements for strength and maintenance. Wood is namely a material which is very environment friendly, the reason being that it immediately enters into the organic cycle.
- Such chemical treatment can consist either of a surface protection, where use is made of chemical impregnation agents for protection against dry-rot and mould fungus, or by giving the wooden item an application of a solution of impregnation agents which wholly or partly spread into the wood.
- Such impregnated wood is used to a great extent for wooden constructions, in that it is well protected and herewith stable, but at the same time the wood is a threat to the environment because of the relatively high content of heavy metals and organic solvents.
- this known method is encumbered with some disadvantages, mainly that the grooves and the channels must extend at an angle in the frame since they must be implemented from the outside and inwards, which is not only relatively difficult to perform for the reason that precision is required to ensure the necessary channel connections, but also that it requires some form of drill gauge or guide in order for the angularly-extending channel system to be produced with the requisite precision.
- the distribution of the impregnation agent in the channel is not uniform, the result of which can be that there will be zones which receive too great a supply of impregnation agent, or there will be zones which are weakly impregnated because of an inadequate supply.
- the impregnation agents dissolved in liquid distribute themselves mainly through the wood grain. Since the grain normally extends longitudinally in the item, the impregnation agent will distribute itself more easily in the longitudinal direction than transversely. However, this is difficult to take into consideration when the channel extends at an angle through the item. Moreover, the transverse extension of the channel system through the grains constitutes a weakening of the wood.
- the invention by manufacturing frame pieces so that the individual frame pieces during manafacture and before assembly are provided with at least one channel which extends longitudinally to and around the middle of the piece, and by providing a hole extending at right-angles hereto between the channel and the side surface of the piece, in a surprisingly simple manner there is achieved a channel system which is not only simple to configure, since it solely comprises channels which extend parallel with the remaining working operations on the item, but which also lies in the centre zone of the item, whereby the radial distance to the surface of the item is substantially uniform.
- the channel can be produced in standard items, since no significant weakening of the wood occurs due to the positioning and extension of the channels respectively around the middle and longitudinally through the item.
- the method is suitable for the manufacture of frames in a rational manner and, since the frame can be protected by a subsequent introduction of impregnation agents, the possibility is provided for the use of unimpregnated wood. There is hereby achieved the most environment-friendly production and maintenance of the wood, and surface treatment such as painting can hereby be undertaken immediately after the manufacture of the frame.
- profile lists can be used in the production.
- a number of frame pieces are involved, namely an upper piece 1, two side pieces 2, a lower piece 3 and possibly a transverse window bar 4 and a vertical window bar 5.
- the upper piece 1, one end of which is shown in fig. 2, comprises a possibly profiled wooden item which in different ways can be provided with rabbets etc.
- two longitudinal holes are also provided, channels 6, a suitable distance inside the frame piece 1, corresponding to the extent of the desired area for the subsequent impregnation.
- a transverse hole 7 is provided which extends through the two channels 6 and ends on the side of the frame piece at either the one or both side surfaces.
- Two screws 11 are used for the closing of the channels 6, but other methods of closing can be envisaged such as plugs or the like which seal off the channels 6.
- assembly joints such as scarf joints or the like are provided between the upper frame 1 and the side frame 2.
- the side frame 2 which is shown in fig. 3, is provided with three channels 6 and a transverse channel 7.
- the two outermost channels 6 are closed with screws 11, whereas the centre channel 6 is provided with a limited opening via a hole in a screw.
- This screw 12 is shown more clearly in fig. 6, in which the hole 13 through the screw can be seen.
- the impregnation fluid in the central channel 6 will be able to seep through the opening 13 in the screw 12 and into the side frame 2.
- the transverse bar 4 which is shown in fig. 4, is provided with three channels 6, a connection channel 7, two closing screws 11 and a through-flow screw 12.
- tracks 10 in which lists 9 can be placed and glued are configured opposite the recesses 8.
- the channels 6, 8 and the transverse channels 7 will be positioned and connected with one another in such a manner that an impregnation fluid, which is introduced via the channels 7, will spread to the places in the frame where the channels 6, 8 are placed.
- an impregnation fluid which is introduced via the channels 7, will spread to the places in the frame where the channels 6, 8 are placed.
- the transverse channels 7 are closed or plugged with a screw 11 or similar tight-sealing plug. With subsequent filling with impregnation fluid, this screw or plug is removed before the filling, after which the channels are closed again.
- the outside surface of the frame pieces 1-4 is configured with a track 14 into which the list 15 can be pressed and secured, e.g. by gluing.
- the track 14 finishes at a distance from the end, while that shown on the under frame 3, see fig. 10, extends for the whole length of the frame piece.
- one of these frame pieces in the assembled frame will be able to be filled with flowing impregnation agent through the transverse holes 7, which are thereafter closed with a screw 11 or the like.
- FIG. 11 there is shown an example of a frame where the top of upper frame piece 1 is configured with a channel 8 which is dimensioned in such a manner that it can serve as a reservoir for the impregnation agent.
- This channel 8 can be closed at the top with a list 9, as shown in fig. 5, or 15 as shown in figs. 9 and 10.
- the advantage gained hereby is that the agent can seep from this reservoir down through the side pieces 2 to the lower piece 3. Moreover, it is easier to mill or to saw a channel in long frame pieces than to drill a channel from the end of the piece, since the length of the drill sets a limit for how long the drilled channel can extend in the piece.
- Subsequent introduction of impregnation agent can be effected by re-filling the channel with the agent.
- a channel 8 in the rabbet which can be covered with a list and which, moreover, is concealed and protected by the window frame when the window is closed.
- frames which are environment-friendly can be produced, and which can be effectively impregnated by filling the internally-lying channel system with impregnation fluid.
- the optimum security is hereby achieved against attack by dry-rot and mould, whereby the demands regarding maintenance of the frame are fulfilled.
- the filling with impregnation fluid can be effected in any known manner, e.g. by injection pump, and can be carried out either from the outside or from the inside at the opening to the channel 7.
