Definitions

  • the present invention relates to a connection assembly primarily for so-called air treatment apparatus housing panels, slabs or the like, of the kind disclosed in the preamble to claim 1 and constituting a further development of the art in our Swedish Patent 7702695-3.
  • the Swedish patent 7702695-3 relates to a connection method which also optionally allows flat or angular connection, e.g. between two wall panels or slabs.
  • the connections obtained have high strength, they have the drawback that the material consumption for support connections and connection members with locking legs is large.
  • Another drawback with the prior art is that it is tied to pre-shaped support sections made on the slabs, i.e. the support sections must be already integrated in the structure during fabrication.
  • connection assembly in the prior art is that it is limited to certain specific slab or module sizes, unless deviating sizes are specially fabricated at large extra cost. Furthermore, the previously known assembly does not permit integral connection of further elements such as bracings and the like.
  • the chief object of the present invention is therefore to provide a connection method primarily intended for air treatment apparatus housing panels or slabs, where material consumption for the different slabs and connection assemblies co-acting in the structure will be low, while at the same time a tight joint with high strength is achieved, and where it is possible to connect slabs of optional sizes without using pre-shaped support sections which are made integral with the slabs.
  • Another object of the invention is to achieve a connection method, which is also easy to use for unqualified or untrained staff and where only a moderate force will be required for thrusting the locking legs on the support sections, which have their legs provided with abutment ends and are situated side by side, e.g. at the edges of the ceiling slabs of air treatment apparatus housings.
  • a still further object of the present invention is to achieve a connection method where production of the components necessary for the method can take place without an expensive fabrication and checking procedure for the purpose of ensuring the intended secure and reliable function. It is also an object of the invention to provide simple and safe bracing and connection of further devices.
  • connection assembly being given the distinguishing features disclosed in the claims.
  • Stability is further increased by utilizing an edge leg as extra support for the attachment of the support section to the edge face of a standard slab.
  • connection section has its legs departing convergingly and directly from its web, to terminate in a pair of stiffening knees or bends with a gap therebetween.
  • a suitable strip is placed between the squeezing legs of the respective support sections.
  • connection assembly is illustrated in Figure 1, e.g. the connection between two ceiling slabs 1 for an air treatment apparatus housing, the slabs having a first slab face 22 and a second slab face 23 which may be the outside and inside faces respectively of such a housing.
  • Support sections 2 have been arranged on the respective slabs 1 in a mirror-symmetrical way, a connection section 3 being used to provide a locked connection between both slabs.
  • connection section 3 has a web 4 from which depart two converging legs 5, so-called locking legs, which are each terminated by an inwardly bent knee 9 and an outwardly bent knee 10 as well as a leg 11 at right angles to the web, a gap 24 separating both legs, this gap being intended for accomodating squeezing legs 7 of the support sections 2 such as to keep the connection locked.
  • the support sections 2 have joining webs 6 and abutment ends 8 as well as a U-shaped edge portion with legs 12 and 25 defining therebetween a gap 26.
  • a resilient seal placed between the squeezing legs 7 has been given the reference numeral 14.
  • connection section 3 has engagement surfaces 13 against the roots of the U-shaped edge portion with its legs 12 and/or the flat faces of the slab 1. These engagement surfaces comprise the outsides of the legs 5 in Figure 1.
  • the support sections are suitably screwed to the side faces of the slabs 1.
  • the support sections 2 are attached by screws 16 through the attachment web 15 of the section and through the slab, as illustrated in Figure 1 by the screw head and centre line of the screws 16.
  • a seal 17 can be arranged between the face 23 of the slab 1 and the attachment web 15.
  • screws 18 are arranged to pass through the edge portion 12 of the support section 2 and into the short side face of the associated element 1.
  • An intermediate seal 17 can also be used here. Where the edge portion is U-shaped, with two legs 12, 25, the screws 18 can be taken through a larger hole in the inner of the two legs, which can then be covered by a plug 19.
  • the first attachment method is particularly suitable for cut slabs, where there are no end walls on the slabs or where such can be insecurely attached and with less dimensional accuracy.
  • Dependent legs 20 illustrated in the Figures can be used for mounting such as extra details or peripheral equipment pertaining to an air treatment apparatus.
  • the dependent legs 20 may be used for supporting the apparatus if they are on the underside of a floor slab 1.
  • the free dependent legs 20 can be used for mounting or bracing an air treatment apparatus, if the support sections 2 are mounted with the legs 20 on the outside.
  • Figure 3a illustrates the connection section illustrated in Figure 1.
  • Figure 3b is a modification of the connection section 3, the web 4 continuing out on both sides in the form of extending flanges folded back on themselves and forming said engagement surfaces, the return part of the double bend then being folded at right angles to the web to form locking legs 5', the lower parts of which are provided with a substantially right angular bend 9 towards the plane of symmetry 27 and the ends of the legs are terminated in a right angular bend 10 such as to form a gap 24 between the legs 5' in which the squeezing legs of the support sections are kept locked.
  • Figure 3c illustrates a modified connection section 3 with outer flanges 21 and at the inner of same locking legs 5" which converge gently towards the symmetrical plane of the section, the lower ends of the legs being folded at 9 such as to be substantially parallel to the web 4 and to terminate in stiffening folds by bending backwards legs 11, with a gap 24 between the two legs in which the squeezing legs of the support sections are kept locked.
  • the legs 11 may form an angle of 90° in relation to the web 4, however.
  • the legs 11 can be part of a 180° fold or they may be directed towards the web 4.
  • a connection section according to Figure 3a can also include engagement flanges 21.
  • the engagement flanges 21 are intended to engage against the upper parts of the edge legs 12, or against the flat faces 22 of the slabs. Particularly with engagement against the slab faces 22, this results in a flexibility in the connection since it is then not absolutely necessary for exact fitting and engagement between the support sections 2 and their adjacent slabs 1, and some clearance or variation in spacing between element and side leg 12 can be accepted.
  • the depth of the connection itself is substantially the depth of the slabs 1 united by the connection.
  • Such a size relationship is to be preferred, of course.
  • the support sections 2 can be screwed solely into the slab face 23.
  • Figure 2 shows alternative embodiments of support sections and/ or attachment of same and/or additional elements.
  • figure 2 a shows an embodiment, which in principal corresponds to the one shown in figure 1 but having a dependent leg 20, the outer end of which is bent in parallel relation to slab 1 to provide an extra leg 39.
  • a dependent leg 20 has been omitted.
  • the support section in figure 2 c lacks both an attachment web 15 and a dependent leg 20, but a Z-shaped section 31 is inserted with one leg into gap 26 and constitutes with its web and its other leg parts corresponding to web 15 and leg 20.
  • an extra section 30 surrounding with a U-shaped part the slab and even being in alignment with that leg of section 31 which corresponds to the dependent leg 20, in which latter region these sections can be interconnected by a screw 32.
  • Section 30 is terminated by a free leg being parallel to the slab and turned away from the assembly.
  • the support section according to figure 2 d corresponds to the one of figure 2 c, but it shows that even an attachment to one of the major surfaces of the slab, preferably adjacent to the narrow side is possible.
  • the very attachment is effected by preferably a striplike section 33, which may be attached to the slab by means of a screw 34 outside the support section.
  • Figure 2 e is similar to figure 2 d, but shows attachment to the slab by means of a screw 35 penetrating webs 12 and 25.
  • a section 33 is thus lacking and the support section is turned 180°.
  • Figure 4 is similar to figure 1, but provides also for a U-section 28 surrounding joining webs 6 and being inserted into both gaps 26 with an intermediate sealing 29 covering the area between both joining webs.
  • the screws 18 may extend through the legs of U-section 28 for achieving a very resistable and completely gastight assembly.
  • seals and gaskets may be provided at optional locations.
  • Said seals and gaskets may be entirely or partly made of elastic material, for instance rubber for rendering any desired elasticity.
  • Figure 5 illustrates, that the gap 26 may be used in a very advantageous way to retain a bracing plate 36, e.g. of triangular shape.
  • a bracing plate 36 e.g. of triangular shape.
  • Such a bracing plate may be provided in two gaps 26 extending within a common plane in a corner area of two adjacent slabs and may be secured by e.g. press rivets 37.
  • the gaps may also be used for retaining / securing additional elements of any kind. If it is desired to maintain substantial elasticity wihtin the area, the gap width is chosen larger or the thickness of the additional elements smaller, so that a certain play allows that elasticity.
