Abstract

A hull construction, especially for water or airborne modes of transport, and constructed out of a number of extended panels (4) arranged on a closed hull frame design, which is preferably of equal width and deployed in a corresponding groove (14) and tongue (15). The hull panels (4) are designed according to the desired frame profile and are placed at an angle of 90-180 degrees in a diametrical plan where the craft's normal direction of forward travel lies at a plane of 90 degrees. The panels' groove and tongue form a rib like pattern on the hull frame's (1) interior made of protruding and reinforcing components (13, 15). The hull frame can be built up in a suspended mode or within a supporting frame (16), transverse bulkhead, or the like, and the hull panels can be arranged to run the length of the hull frame, or the hull frame can be split into two hull surfaces which are adjoined with the help of an outer seam plate, e.g. a keel plate, coaming plate or stern plate. All seams in the hull frame are secured with a seaming glue, more particularly a heat hardened glue with a high anti-shearing factor.

Description

8005125-3 thermal stresses, which can cause weaknesses and bumps or dents in the welded panels. The welded or riveted constructions therefore also become heavy, uneven and unnecessarily expensive.

Attempts have also been made to join panels together by gluing, but even in this case the joining must take place with an overlapping joint or with overlapping jointing tape, and gluing is usually not considered to provide the same safety as a mechanical joint.

The invention has therefore been based on a disc-shaped body made of a plurality of elongate panels which along their one longitudinal edge are formed with a substantially U-shaped groove or groove and along their other longitudinal edge a tongue or spring element, the depth or height is at least partially substantially smaller than the depth of the U-shaped groove, so that a tension groove is formed between the spring element and the groove.

The invention thus relates to a system for producing a continuous disc-shaped body of a plurality of elongate panels, which system is characterized, inter alia, in that the elongate panels are formed along one of its edges with a substantially U-shaped, groove-like groove and along their opposite edge with a spring-like element, which is narrower than the groove groove, and where the groove and spring elements of adjacent panels are arranged to effect a permanent joining of the panels by a method in which spring and groove of adjacent panels are moved together, one or more press blocks are inserted into the space in the groove between its one side and the spring, so that the spring is pressed at least against the opposite side of the groove groove and the press block or press blocks are permanently retained in this space.

A particularly advantageous method for providing a strong and tight joint is that a thermosetting adhesive layer is applied over the spring and / or in the groove groove before the panels are brought together, and that the groove spring joint is heated while maintaining the pressing action between groove groove, adhesive layer and spring. so that a fixed connection is formed between the panels and the press block or blocks. It can often be valuable to apply a thermosetting adhesive layer also between the press blocks and corresponding parts of the panels, so that the entire board body forms a firmly continuous unit. The invention thus relates to both a method and a device for producing cohesive disc-shaped bodies.

Further features of the invention will become apparent from the following detailed description, in which reference will be made to the accompanying drawings. In the drawings, Figure 1 shows schematically and in perspective one side of a disc-shaped body made according to the invention, and Figure 2 also shows schematically and in perspective the opposite side of a disc-shaped body made according to an alternative method according to the invention. Figures 3, 4 and 5 show three different alternative designs of phage pieces and press blocks, and Figures 6 and 7 show a further alternative method for joining the panels according to UPPfï "" í "9 °" between them.

Figure 1 shows fragmentarily a disc-shaped body made of three elongate panels 1, 2 and 3, of which only a small piece is shown. The panels may be made of glued, molded or otherwise made wood material, but they are preferably cast or injection molded profiles of plastic, aluminum or any suitable alloy. For ship or boat building purposes, profiles OV lüffmef fl ll, f- @ X- marine aluminum are considered to be a particularly suitable material.

The panels have a thickness over substantially their entire surface, which is determined by ordinary strength calculations for the material in question, and which is thus not unnecessarily oversized. Along its one longitudinal edge, each panel is formed with a female coupling member 4 in the form of an angle projecting from the main plane of the panel, which forms a substantially U-shaped groove 6 or seam together with the lowest part 7 of the main plane of the panel. Along its opposite longitudinal edge, the panel is formed with a male coupling member 8 in the form of an inverted L-shaped spring member projecting from the main plane 5, the stack 9 of which has substantially the same height as the lowest main plane part 7, and whose foot has a width equal to or preferably less than the width of the groove 6. The male coupling member 8 is suitably displaced laterally a distance from the main plane 5 in the same direction as the female coupling member 4 and a distance substantially corresponding to the thickness of the lower part 7 of the main plane 5. The lower side of the main plane lower flange 7 and the upper side of the main plane 5 may be designed sloping as shown in the figure to give an extended sealing surface, and possibly also the angle to the main plane 5 of the lower flange 7 may be greater than the corresponding angle of the upper edge of the main plane, so as to have the closest possible abutment between the panels. the flat outside of the disc-shaped body. The foot 10 of the spring member 8 is substantially thinner than the height of the outer side part 11 of the female coupling member 4, so that in the case of joined spring and tongue parts a clamping groove 12 is formed, in which one or more clamping blocks 13 can be inserted.

In the event that the panels are joined together without the use of adhesive layers between the spring and tongue parts resp. between the clamping blocks and the corresponding panel parts, the web part 14 of the groove can alternatively be heated to widen, after which the clamping block or clamping blocks are inserted into the groove 12.

When mounting the disc-shaped body, the spring 8 is inserted in a panel into the groove 6 to the adjacent panel, the foot 10 of the spring is pressed against the bottom of the groove, and then one or more clamping blocks 13 are inserted into the clamping groove 12, whereby the spring is also pressed against the lower flange 7. The clamping blocks 13 may be slightly conical wedges, which are driven into the clamping groove, or they may be plane-parallel rods, which in the cooled state are inserted into the clamping groove, so that after assuming the same temperature as the panels have expanded to to provide a permanent clamping connection between the spring 8 and the lower flange 7 of the panel, respectively. the bottom or the life part of the groove 14. In this case, the clamping block or clamping blocks are designed slightly wider than the nominal width of the clamping groove 12.

Alternatively, the living part 14 of the groove can be heated for expansion, after which the clamping block or clamping blocks are inserted into the groove 12.

The clamping blocks 13 can be short pieces of metal rods, but they can also be long rods, which extend along the entire length of the panels.

In order to provide a safer and denser joint, an adhesive layer 15 is suitably arranged between on the one hand the bottom part 14 of the groove and the lower flange 7 of the panel and on the other hand the foot 10 and stack 9 of the groove. In a particularly preferred embodiment of the invention a thermosetting adhesive layer is applied. .ex. an adhesive foil on the spring 8 before it is inserted into the groove 6, and after joining the two parts the panels are clamped together as described above by means of the clamping blocks 13, and then the disc-shaped body is heated along a joint part or preferably in its entirety to so. the temperature to which the adhesive is heard: and during pressing from the clamping blocks gives a strong adhesive joint in addition to the mechanical joint formed during the cooperation of note 6, spring 8 and clamping block l3. A disc-shaped body thus produced is light and strong and can be handled as a coherent unit. However, the sheet-shaped body can be built up successively in the workplace by successively joining a plurality of panels, and in this case a curing of the adhesive layers 15 is conveniently achieved and for all joints after all the panels of the sheet-shaped body have been mechanically joined together. .

The panels can also be designed with longitudinal bars, for example T-shaped bars 16 as indicated by dashed lines in Figure 1. By means of these bars or projecting planes the disc-shaped body can be fastened in a suitable manner, and between the bars 16 can if necessary insulation is applied.

It should be pointed out that the panels 1, 2 and 3 can be mounted horizontally as shown in the figures or standing or at any angle to the horizontal plane resp. the vertical plane.

Figure 2 illustrates an alternative method and device according to the invention. In this case the panels 1, 2 and 3 are joined in principle in the same way as described above, but in this case the clamping blocks are replaced by G-shaped clamps 17 with web 18, top 19 and underside 20 with clamping blocks 21. The upper side 19 abuts against the upper side of the female part 14 of the female coupling member 4, and the clamping block 21 presses the inverted L-shaped spring 8 upwards against the bottom resp. outwards towards the lower flange of the panel 7.

The G-clamps can be made of the same material as the panels or of other material, and they are suitably made of a high-strength material with some spring action. In the lower half of Figure 2, a method for mounting the disc-shaped elements on a vertical bar, a boat frame 22 or the like is shown. In this case, the life 18 of the G-clamp is slightly widened, and the clamp is fixed as a rule by means of rivets 23, screw or bolt. The assembly and assembly of the disc-shaped body shown in Figure 2 takes place as follows: The spring 8 or the groove 6 of a panel is coated with a layer 15 of a thermosetting adhesive, and the spring 8 of one panel is inserted into the groove 6 of another panel. The foot 10 of the spring 8 is pressed by means of a suitable tool against the bottom of the groove 6, and from the side a suitable number of G-clamps 17 are inserted. The G-clamps may consist of an elongate strip extending along the entire joint between the panels, or it may be of short clamp pieces as shown in Figure 2. In this latter case, suitably shorter or longer clamping blocks of substantially the same type as shown in Figure 1 can be pressed into the clamping groove 12 between the G-clamps 17. If an extremely dense and strong joint is desired, a clamping blocks of the same length as the distance between the G-clamps are applied in the clamping groove. The larger or smaller loose clamping blocks 13 can be inserted in such a cooled state that, after heating to room temperature, they achieve the desired pressing effect. If desired, the disc-shaped body can be mounted on frame 22 or bolts by riveting, screwing or otherwise attaching the G-clamps 17 to the frame. After completion of the entire sheet-shaped body, a heat treatment takes place in the event that layers of glue or adhesive foils have been applied between the spring-groove joint and any other joints, for example by covering the body, placing it in an oven, treating it with heat fans or in another way. The body is then heated to such a temperature and for such a time that the adhesive layers harden. If necessary, final adjustments of the body can be achieved by inserting separate clamping blocks between the G-clamps.

The smooth surface of the body thus achieved does not normally need to be sanded, plastered or painted.

Figure 3 shows how the clamping block 13 'is designed with a nose 24 facing away from the planes of the panels, which engages above or behind a corresponding nose or hook 25 at the end on the side of the female coupling member. This coupling provides a very strong and secure connection, especially if an adhesive foil is applied over the entire joint surface between the clamping block on the one hand and the male and female coupling means on the other hand.

Figure 4 shows how the clamping block or G-bracket is designed with a T-bracket 26 projecting from the planes of the panels, which can serve as a support or support arm for the disc-shaped body, or in which all kinds of different members such as insulation etc. can be attached and supported. In this case, the upper overhang 27 in the G-clamp has been able to be lowered so that clamps can be tilted on the female coupling member without having to be pushed in from the side as described previously.

Figure 5 shows an alternative to clamping blocks with support bracket, where the upper overhang of the G-clamp is replaced with a separate strip 27, which is fastened with screw 28, rivet or otherwise in the bracket 26 after the clamp is mounted in the coupling joint, and which extends over the life of the female coupling member 14 and forms a fuse against release therefrom.

Figures 6 and 7 show an alternative to the G-bracket described above. The clamp is in this case made in two parts, a lower hook 29, which in the manner described above is adapted for insertion into the clamping groove between two panels and an upper hook.30, which is intended to be able to be attached to the web 18 'of the lower hook 29'. and to be able to abut with an upper side 19 'against the upper side of the life of the female coupling member 14. For this purpose, both the lower and the upper hook are formed with holes 31 for screws or bolts.

This design of the G-bracket allows an assembly of panels of varying size on the coupling means.

The embodiments of the joint clamp shown in Figures 4, 5 and 6 enable a reduction of the goods in the coupling means, since the coupling means when using such clamps are subjected to very little rotational stress during assembly and use. The clamp itself constitutes the main load-bearing suspension part.

It is to be understood that the foregoing description and the embodiments of the invention shown in the drawings are merely illustrative examples, and that various modifications of the method and apparatus may occur within the scope of the appended claims. For example, the profiles can be locked to each other by driving scissors, rivets, pins or similar elements between the female part 14 of the female coupling member 4 and the foot coupling member 8D 8D. These parts can be pre-drilled for the pin, screw or the like, but it may be sufficient to only one part is pre-drilled so that a locking is achieved by upsetting the material into the other part or even by upsetting the material straight through both parts.
