• An advantage of this embodiment is that the elements can be manufactured in simple manner from readily available basic material such as the profiles.
• the desired or required strength can be obtained by selecting the respective wall thicknesses of the support members and connecting members, which determine the strength to a significant extent.

• the floor construction comprises buffer or kick edges arranged along outer edges of the floor plates. This also has the advantage of the possibility of prefabrication on the basis of a previous form definition. In prior art floors the plates were measured during fitting, which again also required great skill. This work further had to take place in the space in which the floor was also being placed, and such spaces are in general rather inaccessible for such operations.
• the construction preferably comprises fastening means comprising locking members which extend through the plates and can be operated from the upper side, and which engage through rotation under a support member or a connecting member.
• the operating means hereof are preferably countersunk into the floor element.

• a first preferred embodiment according to the present invention (fig. 1) relates to three beam parts 1,2,3 of a floor construction.
• Connecting beam 3 is manufactured from a profile comprising side walls 32,34 and lower walls 33,31.
• This profile is preferably manufactured from a metal.
• a metal is preferably a metal with high degree of inertness, such as a stainless steel, aluminium and the like.
• Such a profile can of course also be manufactured from more low-grade types of metal.
• hooking members 36,37 Situated at the ends of the connecting beam are hooking members 36,37, which are arranged in line with side walls 34,32 respectively.
• the upper wall 31 extends via part 35 in a manner such that hooking members 36,37 are mutually connected by means of this part of the upper wall.
• This connecting part is not essential, but does provide some strength.
• the shape of hooking members 36,37 and upper wall 35 are cut out of a profile part. Use is preferably made here of laser cutting, since a suitable precision can hereby be achieved in the manufacture of these parts. This cutting technique is not intended however as being limitative. Other cutting techniques can also be used.
• the embodiment further comprises support beams 1,2. These support beams can be embodied integrally. For an improved fitting of the support beams a coupling is however provided to enable mutual coupling of " two relatively short support beams in longitudinal direction in simple and robust manner. In this preferred embodiment shapes are cut for this purpose from a beam, whereby the two beam parts 1 and 2 can be fitted to each other while also achieving that after fastening they no longer have any, or hardly any, freedom of movement in length, width and height direction.
• Support beam 1,2 is defined in its entirety by means of upper wall 11, lower wall 10 and side walls 12,14.
• Support beam part 1 is defined as comprising the upper coupling.
• Support beam part 2 is defined as comprising a lower coupling.

• An extended protruding part 23 is arranged on upper wall 11.
• the wall of assembled support beam 1,2 will be substantially closed all around after the upper coupling and the lower coupling have been placed against each other. It is however also possible to provide such a coupling with an opening, for instance on the underside, for passage of for instance moisture. It is further also possible to leave small openings for the purpose of compensating imperfections in the cutting process for the manufacture of the parts of the coupling, for instance close to cut corners, so that the positioning effect of the coupling is maintained while possible cutting imperfections will not stand in the way of a correct fit of the coupling.
• Such cutting imperfections can for instance be caused by an askew orientation of a saw or laser beam, or by the occurrence of for instance burrs.
• chamfered corners do not therefore form an essential part of the invention and can also be omitted.
• ⁇ inner corners' with a rounded edge in order to compensate for possible burrs in outer corners.
• Such a rounded edge can be made by cutting for instance a small circle round the inner corner.
• a protruding part 25 is provided in each of the wall parts 18,19 of the lower coupling of support beam part 2.
• protruding parts 25 By fitting these protruding parts 25 into respective openings 24 of side wall parts 16,17 of the upper coupling of beam part 1 a shifting of the two beam parts 1 and 2 relative to each other after coupling thereof can be prevented in effective manner, whereby the length of the resulting part is defined and the couplings remain in position in the longitudinal direction.

• Figure 3 shows an alternative variant with two openings at the same position on the beam. Situated between the openings is a bridge part 52 for further strengthening of support beam part 50.
• FIG. 4 shows a further preferred embodiment according to the present invention.
• Two support beams 1 are shown which support by means of struts 56 on the construction of the space in which the floor must be placed. These struts support for instance on structural elements of a ship or a hull of a ship.
• connecting beams 3 Arranged between the two support beams 1 are connecting beams 3, which are hooked into support beams 1 by means of the oblique hooking elements.

• a buffer edge or kick edge is provided which is attached to a floor frame and made to size in situ.
• This buffer edge is here generally welded fixedly to support beams for the floor. This requires a large amount of custom fitting in situ, wherein the working environment is rather impractical for the workmen.

This is possible in that the overall form of the floor is predetermined as a whole, after which the cuts in the plate can be determined by means of computer calculations.
