- Fig. 7 is an alternative embodiment of the rail system intended for a U-shaped bar; and Fig. 8 illustrates the sleeve of the rail system of Fig. 7, part of the sleeve also being shown in an enlarged view.
- the system comprises bars 1 having a rectangular cross-sectional shape, such as wooden bars, and supporting level-adjustment means 2.
- the level- adjustment means comprise rods 4 and sleeves 3.
- the sleeves 3 are attached to the bars 1 in a manner to be described in closer detail in the following and the rods 4 are attached in the sleeves.
- Such attachment is effected by means of internal threads formed in the sleeve 3 and matching external threads formed on the rods 4, at least in the upper ends thereof facing the bar, which arrangement allows the rods to be screwed into the sleeves.
- the rods are caused to engage with the sleeves and further, the lengths by which the rods project beyond the bar may be easily adjusted by turning the rod inside the sleeve.
- the rods 4 are hollow and at their ends turned away from the bar they are provided with holes 7 for reception therein of fasteners 5, such as screws or nails, by means of which they may be attached to the support structure.
- the cavity 6 in the rods preferably has a cross-sectional shape, at least at their upper end accommodated inside the bar, that is suitable for tool engagement.
- the cavity may have an hexagonal cross-sectional shape allowing the rod to be turned by means of an Allen wrench.
- both the attachment of the rods by means of the fasteners 5 and the adjustment of the rods vertically may be effected from the upper side of the bar that is turned away from the support structure.
- On top of the bars is subsequently applied the external surface material 8 of the wall or the floor.
- Figs 2a-c illustrate the bars 1 in more detail.
- the bars are provided with through holes 9, in which the sleeves 3 may be inserted, and with abutment shoulders 10 against which the sleeves 3 may be caused to engage.
- these abutment shoulders may be configured in such a manner that the upper part of the hole facing away from the support structure has a somewhat larger diameter size than the lower portion.
- the holes may be either drilled in the bars in advance or be drilled in connection with the mounting. When the holes are pre-drilled, they could either be drilled in predetermined suitable places or in a number of places, an arrangement which allows the most suitable holes in any particluar case to be chosen during the mounting.
- the sleeves 3 are shown in closer details in Figs 3a-c.
- the sleeves are internally threaded and at the upper portion, i.e. at the end intended to be turned away from the support structure they are provided with locking protrusions 11 intended to engage with the abutment shoulders 10 formed in the holes 9 of the bars. Further, the sleeves are provided at the very same ends with longitudinal slits 12 and they are made of a material which may be bent resiliently somewhat outwards.
- the sleeve may be forced into a hole in a bar from the lower face thereof, whereby the locking protrusions 11 of the sleeve are forced somewhat towards one another, whereupon it is pushed upwards in the hole until its locking protrusions move past the abutment shoulder 10 and snap outwards to lockingly secure the sleeve.
- This fastening arrangement is advantageous since on the one hand it is rapid and simple and on the other it may be locked and if needed be detached completely manually without the use of tools or with the aid of simple tools only.
- the sleeve ends are provided with pro ⁇ jecting flanges 13 against which the bar 1 is supported.
- the flanges 13 may be prolonged by insulation carrier means 14 which, when the sleeve is secured in a bar, project beyond the bar 1 to carry insulation material 16 (for thermal or sound purposes) or the like, as illustrated in Fig. lb.
- insulation carrier means 14 which, when the sleeve is secured in a bar, project beyond the bar 1 to carry insulation material 16 (for thermal or sound purposes) or the like, as illustrated in Fig. lb.
- brake-off slits 15 preferably are provided to allow the insulating carriers to be removed in a simple manner without damaging the flanges, should they not be needed.
- rubber seals 17 preferably are positioned in order to provide resiliency and/or sound reduction in the floor, or the like.
- FIGs 4a-c A second embodiment of the bar system in accordance with the invention is illustrated in Figs 4a-c.
- the system comprises bars 20 having a U-shaped cross-sectional configuration, such as steel beams.
- it comprises rods 4 and sleeves 21, the first ones being of equal configuration to those of the previous embodiment but the latter being somewhat modified.
- the bars, illustrated in more detail in Figs 5a-c, are also in this case provided with holes 22 on the main face 24 of the bar but in this case the abutment shoulders are provided by slits 23 formed on the legs 25 of the bar.
- these notches in the bar may either be formed during the very mounting or in advance.
- Reference 44 designates a transverse recess formed in the legs 25, allowing the bar to be bent at point 45 on its main face 24 in order to allow adjustment to a desired change of inclination of the finished floor.
- the sleeves shown in more detail in Figs 6a-d also in this case comprise an internally threaded hole 26.
- the locking projections 27 are, however, formed on separate arms 28 which are arranged in parallel with the hole-delimiting walls.
- These locking projections 27 and arms 28 are positioned on the flange 29 projecting from the sleeve and are arranged in such a manner that when the sleeve is pushed from below into the U-shaped bar 20 they will be positioned externally of the legs 25 and thus, from the outside, snap into and lockingly engage with the slits 23.
- the flanges 29 may be prolonged by brake-off insulation carrier means 30 and with rubber seals 31.
- FIG. 7 and 8 Another manner of causing the sleeves 40 and the U- shaped bar 41 to engage in a simple and removable manner is shown in Figs 7 and 8.
- the legs of the bars have been bent inwards into the shape of flange edges 42, at least below the holes, and in a corresponding manner the sleeves have been provided with grooves 43.
- the sleeves are inserted sideways into the bars from the lengthwise direction of the bars until they assume a position opposite a suitable hole.
- the bar system in accordance with this embodiment functions in a manner identical to that described with reference to the previous embodiments .
- One advantage gained by the system in accordance with the present invention is its ability for adaptation to most types of bars normally used, such as rectangular wooden bars, U-shaped steel bars, and the like.
- a further advantage is that it may be mounted, adjusted, and dismantled simply and rapidly and that the main part of the work may be effected from the outer face, allowing the work to be performed quicker and without being as demanding as hitherto.
