How to design the stairs of our house? Read our tips! In order to design and build a staircase to our house we need to take several aspects into account: first legislative, then ergonomic, structural and safety and finally aesthetic. For proper implementation it is advisable to rely on the expertise of a technician who will abide by the Municipal Building Regulations, for the regulatory part and will take into account appropriate design criteria, especially by monitoring the structural aspect. When you design a staircase, you must calculate the space and the height that you have available. Another parameter to be considered is the slope of the ramp generally between 20 ° and 45 °, which usually are much steeper, as their use is private. So that the body staircase is comfortable it is necessary to establish a proper relationship between riser and tread. The riser is typically between 15 and 20 cm whilst the tread is calculated using empirical relationships based on the work done by the in addressing the uneveness In fact, with the variation of the slope, the user tends to change the length of the stride in such a way that the work done to overcome a step is equal to the work done to accomplish the same stride on the level. This implies that the increase of the tread corresponds to a reduction of the riser and vice versa. To date, the formula mostly used is that of the architect François Blondel 1675. According to studies by the French architect the effort of raising the foot is vertically double that to move horizontally; given a length of about 64 cm for a comfortable pace on horizontal level , it can deduce that the tread depth of the step must be the result of the subtraction of said length of twice the value of the riser, ie: 2a + p = 62 ÷ 64 cm. Where a is the value of the riser and p is the value of the tread. Here is a short example. To cover 270 cm height with a riser of 17 cm the following calculation is made, as mentioned in the previous step, to determine the number of steps: 270/18 = 15 steps. Multiplying the number of steps by the 28cm tread you obtain the plan of the staircase: 15x28 = 420 cm. For stairs that have the handrail, the safety regulations stipulate that it should have a height between 90 cm and 1 m and a minimum distance of 4 cm from the wall. The railing placed on the void must have a minimum height of 1 m and beimpraticable by a 10cm diam sphere (DM. 236 06/14/89). It is commonly accepted that poles must be vertical and not horizontal to avoid the dangerous "ladder effect". What types of stairs? After seeing the rules for correct planning, we can proceed with knowing the types of staircases existing. Ramp of stairs: The most widely used because most comfortable. Consisting of two parallel ramps at angle, and an intermediate landing. Very often, the two ramps are connected by steps in a fan shape, to make the most of the space. A spiral staircase: suitable for small spaces, because the occupied surface is only the size of its diameter. It can be circular, square or elliptical. The steps are anchored to a supporting structure, said plug or column, fixed to the floor and ceiling. Mariner or staggered treads: made of two uprights and rungs or steps to narrow treads. They connect lofts and libraries. But they are uncomfortable and are rarely designed to be used between two floors. They often have a 20cm riser, so the stairway is somewhat 'steep and dangerous. In essence, a staggered tread staircase is divided into two adjacent ramps and, in fact, offset, each of which will be inevitably used only by the same foot, right or left. The route is, therefore, made up of a succession of steps that must be alternately trampled in a specific order Retractable . It folds into itself and fits into a compartment that contains it. It can be made of aluminum or steel, or lightweight materials. Is it suitable to get to areas not often used and disappears when not in use.
