Stairs
|
Designing stairs is always a challenge, especially if you need to create exact and precise designs as with precast elements. Allplan provides several methods for designing and reinforcing stairs. |
The component designer allows you to accomplish this task in no time at all. Stairs are provided as parameterized components. With just a few entries, you define the geometry and place the stair in your building. That’s all! Correspondingly, parameterized reinforcement is available. All you need to do is define parameters. The reinforcement is shown attached to the cursor and can be placed in a component where it then expands to adapt to the outline. The illustrations show how easily you can create stairs using Allplan. |

Buildings and staircases are designed floor by floor. Reference planes are very useful. Inclined elements adapt automatically and walls, windows and doors update automatically to reflect any changes you make. To get a better overview, it is advisable to design the walls, slabs and staircase separately. Now use the component designer to create the first flights of stairs, which need to be brought into the correct position. The next step is to create walls and slabs, which are also precast elements in this construction project. The walls are double walls and the slab is designed as a half floor. Some walls are equipped with layers of insulation. The walls are created in plan; the height is governed by the plane. Doors, windows, electrical installations etc. are integrated. In particular, the supports for slabs and girders need to be taken into account. Allplan handles the remaining work – nodes, joints, reinforcement – almost automatically. Creating the slab is just as easy as the principal geometry has already been defined. The walls of the next floor are outside. Consequently, a layer of insulation is applied. As you can see, the devil is in the details. But these illustrations also show that this approach eliminates any problems during production and on the construction site from the get-go. Even the height is checked. It took the Allplan user who has designed this staircase less than two days to create the design, general drawings, production drawings, reinforcement drawings and all the lists and schedules for reinforcement and fixtures. Two days? Bear in mind that there are many details, which need to be defined and fitted precisely into the design. In particular, this applies for the inclined elements, fixtures connecting the precast elements, stair support etc.. Consider the time and effort spent doing this as a good investment - after all, questions did not arise during production or on site and everything was completely trouble-free. Allplan includes a special stair designer that allows you to create not only standard stairs but also free-form stairs. Here, too, entry is based on parameters. This way, you can design any stair such as this spiral stair in as fast and uncomplicated a manner as possible. You can use the plug-in FormBau to create stairs that are even more complicated. FormBau lets you generate formwork with just a few clicks. This data is then transferred to milling machines. |
