Definitions
- the present invention relates to a fixed ladder central.
- This type of scale is particularly useful for access, usually infrequently and for technical reasons, in places with difficult access or dangerous, ie facades, aerial masts, particular GSM antennas etc.
- the present invention provides a fixed ladder with steps that can be reversibly attached to variable heights.
- a ladder comprising a central upright with rungs extending from of the said amount in which the amount of the side runners a slide adapted to receive the means of setting of steps.
- a ladder with a central stud that includes a rail security.
- the rail is provided with a dish on which can slide or roll an anti-fall cart vertically of known design.
- the user of the scale is therefore secured by an anti-fall trolley connected to a rail integrated in the amount of the scale.
- the steps can be moved vertically to fit the configuration and relief of the ladder support fixed. They can be quite removable. We provides for this purpose, in the central amount, and on the side opposite of the aforementioned dish, a slide in which the steps are fixed.
- this slide would also allow to insert bolt heads, for example M10, for fix the ladder on the support by means of a flange.
- the steps planned, perpendicular to this amount preferably have a solid triangular shape or trapezoidal reversed. They can be trained by folding of a stainless steel or aluminum surface.
- the surface is triangular or trapezoidal, the edge of the longer side being bent to make it perpendicular, and folded advantageously a second time at a distance different, to form the support surface of the feet of the user.
- This surface can be covered with a anti-slip material.
- the steps can exceed on each side of the rail, but also extend alternately on one side then the other, staggered.
- the ends of the rungs may have lugs or stops formed by straightening (folding) of two growths of a piece with said triangular surfaces or trapezoidal.
- two holes are provided in the triangular or trapezoidal surface to pass bolts, for example two M10 bolts, whose head is placed in the slide, and who will fix the rung by two matching nuts.
- steps between steps can be set for example from 225 to 300 mm while respecting the standard ISOEN14122-4.
- the rungs are also adjustable in height for allow for a shift of these if an obstacle becomes present during assembly. It can be edges, An anchor clamp fixing GSM antennas, pipes, tubes or ducts, etc.)
- the slide can also be used to fix with the help of bolts flanges or fasteners to bracket (antenna, etc ..).
- the complete scale is assembled by the superposition and solidarity of several segments central amounts.
- Fig. 1 represents a segment of scale according to the invention comprising 3 steps.
- Fig. 2 represented a segment of scale with a another embodiment of the steps.
- Fig. 3 represents a cross section of the amount.
- Fig. 4 represents the scale of FIG. 1 side view opposite.
- Fig. 5 represents the scale seen on the slice.
- Fig. 1 represents a scale according to the invention seen in elevation on the ladder side.
- a scale 1 composed of a quantity central 2 and three steps 3 fixed at heights varied and adjustable.
- the steps include a trapezoidal vertical surface 33 and a surface 4 support perpendicular to the scale, with a flange 4 'extending downwards. These surfaces 4 and 4 'can be obtained by folding and folding the upper edge of a step surface 33.
- the surface 4 can be coated with a non-slip material.
- the steps are maintained by nuts 6 associated with bolts whose heads can slide in a slide 7.
- Fig. 2 represents a 3-step scale segment comprising another embodiment of the steps, these extend alternately on one side then the other of the central amount. It will be understood that general can also be associated with segments ladders of complete rungs according to fig. 1 and rungs each extending on either side of the amount central. This makes it easier to adapt to irregularities of the support.
- Fig. 3 illustrates a cross section of the amount of the ladder and thus shows the slide channel 7 as well as the flat 8, opposite, forming with 9 a rail on which can slide or roll a safety trolley not illustrated.
- An example of such a trolley is described in EP 1,253,280.
- Fig. 4 is a side view of the scale. We distinguish the surfaces 9, 10, 11 of the section of FIG. 3. We have added a flange 12 fixed by a bolt 66.
- Fig. 5 is a scale view of the opposite side to levels.
- an anchoring piece 12 is shown in the support of the ladder maintained by a bolt 66 whose head is also in slide 7.
