The core-insulated double wall, as a new module of Allplan Precast, is a new development, which drastically reduces the planning effort, even for complex, insulated walls. Parametrised entries for connections, joint alignments, different shell thicknesses, insulation, laying functions for reinforcement and fittings bundle many moves and allow compact and efficient processing. The thermal wall saves time in everyday planning life, as well as being flexible and open to difficult tasks.
The software requirements for robotic production of insulated walls are quickly listed. Easy to plan, like a double wall, but with the special feature of insulation that naturally complicates this. When looking at the details of what the program can do, it is initially noticeable that a “quick entry” can be configured for is "basic" standard cases.
Compact, clearly understandable – the new interface
The planning steps are anchored in functions such as “wall structure, connections, partitions, reinforcement”. The entry is parametrised and the effects of an entry are immediately visible. With simply structured walls, the entry is not only reduced to a minimum, but values that are not even required. Thanks to many years of experience in the application, success has been achieved in displaying the wealth of functions compactly, clearly and easily understandably.
Wall construction made easy
Walls are arranged according to types, such as: Double wall with internal insulation, or core-insulated wall. For this wall type, the shells are defined, attributes such as thickness, quality, display types are specified and the geometric arrangement of the shells among one another takes place. If there are offsets in the shells, massive stripes are envisaged on edges or openings, or the insulation has different areas of thickness. The standards can be saved as favourites, so that this definition can be a one-off process. All the more, as each individual element can be accessed during project processing and these basic settings can be precisely modified. This even goes as far as modifying the thickness of the wall (architectural wall), starting point of the design, whereby the entire wall type can then be modified accordingly.
Wall connections – everything is feasible
As with the previous applications, after defining the wall types, the connections are set. The connections are predefined so that the solution can be obtained at the push of a button.
Vertical joints follow a scheme If a connection should not exist, the conceptual scheme for how to enter the system is quite simple. One imagines that all lines intersect and the lines and intersections are now threaded on, which are intended to illustrate the joint run.
Joints that are based on the profile of the formwork Horizontal joints are very frequently based on the profile of the formwork. And according to these, the series of lines is defined, e.g. a line such as tongue and groove. Now, these only need to be allocated to the walls/shells.
Design scope through an arbitrary number of running joints. The joints are/become 3D bodies. There are two advantages linked to this. For one thing, one has precise quantities, important for calculation and invoicing and then these joints can also be tilted arbitrarily, in order to design angled precast parts.
In this way, the facing shell can be broken down into parts, in order to get a grip on them constructively, as well as in terms of design.
Reinforcement flexible and automated
If the precast part is highly complicated, a quasi manual reinforcement cannot be avoided. Of course, designing takes place in table projection and receives a 3D reinforcement basket. This ensures that the reinforcement is correctly displayed in each section and in each view, as well as being consistent within itself, with the excerpts and steel list.
However, walls can also be reinforced in an essentially automated manner. For each shell, two reinforcement units can be predefined. A unit can be comprised of mats and additional longitudinal and transverse bars. Even bent mats can be processed in order to integrate a massive strip with a needle-shaped reinforcement, all at once.
Reinforcement can also be automatically created for the air shaft, i.e. for the core concrete.
Lattice girder or needles for the composite
The laying of girders takes place automatically according to specific rules for consideration of the insulation. As an alternative to this, there is the automatic laying of Schöck ComBAR thermal anchor system. Programmed according to the regulations for the permit, so that quality-assured laying and secure installation are ensured. And, of course, fittings can be manually entered in all layers.
Innovations for production
Plotter, laser, formwork and reinforcement robots, right up to the data required for the mat welding system. When looking at somewhat more complex details and relevant border reinforcement, these can be immediately supplied by the mat welding system, when it is recognised that conventional interfaces are no longer sufficient. With the new program, we are advancing forward into the 3rd dimension, together with manufacturers of host computers. Multicoloured concrete in one shell, massive strips, bent mats, are key words that clarify this.
Automatic plans and individual layout
The methodology for the derivation of the element plans from an overview plan or model is unique. Initially, a generally valid plan layout is defined for a specific type of precast part and specifications are made regarding the appearance of the plan. With this unique preparation, it is guaranteed that a fully automated plan is obtained for basic components, according to the individual requirements. If the parts become more complex, refinement can take place according to all rules of planning. Geometry, reinforcement, fittings can be switched and displayed separately. The element plan module is also described in more detail with the iParts and in further chapters.
Conclusion
With the thermal wall, one is equipped for the increasing demand for insulated walls. The previously complex engineering design work is significantly facilitated by strong, program-supported functions. 3D makes everything immediately assessable and ensures the planning quality. Last but not least, without any extra effort, one receives the complete materials management and data for controlling the system.
