At first, Daniel Maire built himself a concrete staircase. Then he tiled it, after having equipped with stair noses and skirting made to measure in solid oak. Remained to give it a matching ramp, home made of course!

See the plan of this realization: Customize a masonry staircase: the plan

The staircase is in two flights separated by an intermediate landing. Only the upper part requires a ramp, as well as a railing at the level of the floor. The lower end is closed by the wall (the central wall carrying the ends of the upper steps).

■ Step nosings completed with a back molding, are pegged and screwed into the concrete while the baseboards are simply glued to the wall. The former are specially profiled to allow tiles to be laid after the fact. The skirting boards, in two joined "L" elements, are chamfered on their outer edges and notched with the shape of the steps noses.

■ The start and end columns of the boom, 85 x 85 mm in section, consist of two U-shaped sections. Assembled by groove and tongue, they form a central recess of 25 x 25 mm allowing to put on a solid iron of the same section. The starting post undergoing the strongest mechanical stresses, its iron is sealed in the first step of the top flight. That of the arrival post, which connects the ramp and the guardrail, is just tugged into the floor of the floor.

■ Welded at the top of the anchors, a large threaded rod holds each post in place with a nut and a large interlocking washer. This device is then covered by the pommel: a block of 95 x 95 x 64 mm, chamfered edges. Upstairs, the railing ends in a pegboard-screwed into the wall.

■ This quality achievement involves a lot of wrought work and routing, the use of a combined wood is essential. For reasons of economy, the wood is bought in a sawmill.

The frames of the stairs

The two anchors are debited to a length of 110 cm (start) and 90 cm (finish) respectively, then extended by a threaded rod of Ø 18 x 140 mm welded (and centered) at the end. The starting iron is sealed in the first step about ten centimeters deep, carefully controlling its verticality on two contiguous faces. To secure the finish iron in the floor of the floor, a plate flat iron 60 x 30 x 4 mm is welded (after drilling) at its base.

Baseboards and threaded rods

Baseboards and threaded rods

The lower end receives baseboards on both sides of the steps, the upper one is trimmed on one side only. The difference in the length of the end-welded threaded rods is the material available.

Starting post and tiling

Starting post and tiling

The reinforcing iron of the starting post is sealed in the step before laying the tiles. At the base, a Plexiglas plate forms a hollow joint insensitive to the effects of cleaning products.

The noses of steps

After wrought, the wood is molded "per kilometer" to the top. In addition to the facing moldings, two other machining operations are carried out: a 5 x 12 mm groove on the underside for the vertical tile bending, and on the top a 30 x 17 mm groove that will receive those of the steps.

■ The steps noses and their returns are cut to length, according to the dimensions of the staircase, then the second are cut at the back and rounded. The pieces are then sawn and grooved for assembly by false tongue. To fix them in the concrete, two milled holes are pierced in the rabbet of the nose and that of the returns.

■ Before fixing preferably, the parts are melted and covered with two layers of water-based glaze interspersed with a ginning. This avoids staining the tile, then placed, and facilitates the cleaning of burrs mortar or glue on the wood.

Profile of walking noses and returns

Profile of walking noses and returns

The profile of the steps noses and their returns allows to seal the tiles in recovery. To do this, they are grooved on the underside and furrowed on the top, on the side.

Skirting boards

Make two pieces of assembled flat angle bracket, they are cut into a sheet of 40 x 16 mm section. A cardboard template makes it possible to postpone the profile of the stair nosing on the vertical part and notch it precisely. Once assembled, their front edge is cut at an angle of inclination of 5°. Their outer edges and the one that connects them to the plinth below are finally chamfered. Again, baseboards are glazed before being glued in place.

Ramp and railing

These protections have a complex trellis pattern, which requires the tracing of two scale 1 tricks (ramp and guardrail) on large sheets of strong paper or cardboard.

It is thus easy to dimension the "small woods32 x 32 mm and the bars of 47 x 47 mm, which frame them.The whole is connected by pins of Ø 8 mm and screwed (in parts high and low) between two squares of 20 x 20 mm. are glued in a machined groove in the handrail and the corresponding low rail, themselves journalled in ends (Ø 10 mm) to the posts.

■ The parts being corrected according to the flow plug, the half-poles receive a large central groove of 12.5 x 25 mm for the anchor iron and then, on both sides, two grooves of 8 x 15 mm. This allows them to be assembled next with a false tongue of plywood 8 mm.

■ After drying, the posts are sawn to their final length and recessed at their top to accommodate the lock nut. Their installation is carried out by inserting at the base a Plexiglas plate of 75 x 75 x 4 mm, which will form the hollow joint. The wallboard of the floor is sized according to the height of the plinth, so that its top aligns with that of the post of arrival. Its wall fixing is prepared in advance: it consists of three lag screws, distributed in the height, whose heads disappear in countersinks before being covered by wooden plugs.

Posts and recesses

Posts and recesses

The posts are in two parts hollowed with a wide middle groove and assembled by false tongues. Which, once formed, household in the center a square recess for the iron anchor. Another recess is made at their top, at the mortiser, to accommodate the clamping device. The circle drawn in pencil corresponds to the diameter of the puck.

Smooth, handrails and trellises

■ The rails and handrails, profiled at the router (see section), are presented on poles and flanges, with wedges and clamps, to trace their length in a precise way. Their positioning is also spotted on them in anticipation of their assembly; the cutting angles of the boom elements are raised with a false square. The trunnion housings are then drilled at their ends and then transferred to the posts using flanged centering devices.

■ The small woods of the trellises are placed on the screen and their respective lengths are carefully marked: the cutting, with a circular saw, is done in series in order to limit the trolley settings. The log holes (8 mm) must be drilled at their ends and chamfered at their longitudinal edges. Always based on the sketch, they are assembled "sign" by "sign"With a vinyl glue quick setting.It is, again, easier to vitrify all before putting it, even remaking retouches afterwards.

Assemblies and assemblies of the ramp

Assemblies and assemblies of the ramp

The assemblies made, the trellises are rotated laterally to their bars and then, in the upper and lower parts, the squares. These are, before final assembly, glued in the groove of the low rails and handrails.

knobs

■ When everything is in place, the studs are locked through their nuts, while the wallboard is tapped with a ratchet. Finally, the knobs are posed. Their base, previously pierced in the center, is equipped with a double threaded socket to tighten them on the threaded rods, by inserting a plate medium 75 x 75 x 3 mm.

Poles and end board

Poles and end board

The posts are strung on their frame and locked by nut and washer, while the end board is anchored in the wall. If the locations are accurate, the set is quite easy to set up.

Press grooves

Press grooves

The use of the stops of the mortiser makes it possible to obtain a plane background. If the pole fitting grooves on the iron are accurate, the quality of the anchoring of the guardrail or ramp is ensured.

Strong fixation

Strong fixation

Seen in low-angle, the pommel reveals the medium plate on which it is placed. For a strong fixation, it is strongly recommended to screw it on the threaded rods.

Grid patterns

Grid patterns

The important adjustment work required by the trellis is largely forgotten by the elegance of the result. The judicious distribution of the bars makes it possible to respect the regulation spacing of 11 cm.

Security side

The set meets the regulations in force, which imposes a ramp height of 90 cm to the right of the steps noses and 100 cm on finished floor for the guardrail. The spacing between the bars of the trellis pattern is for the same reason limited to 11 cm.
