Building blocks as molds

In addition to a number of other properties, building blocks for building construction purposes must have sufficient compressive strength, although the the mortar layer connecting them is usually less pressure-resistant. Both compressive strength is seldom exploited * That is the case with stones or stone-like materials high density is disadvantageous for transport and processing wages, especially since it is too small manageable stone sizes.

A different approach is used for steel frame or reinforced concrete frame construction, in which their high compressive strength is largely exploited, but all other wall parts are inserted as non-load-bearing filler parts * However, for many reasons, this type of construction is only justifiable and rational for large buildings. For simple to medium-sized structures, the well-known, costly "brick construction ^{11" has been used} for the shell construction, including subsequent interior and exterior plastering for the prefabricated construction.

The protection request relates to a construction method that enables wage costs with appropriately shaped and dimensionally stable building blocks to reduce their processing for joining and juxtaposing while avoiding mortar, and also for the constant checking of the height and side alignment. this will achieved through certain surface shapes of the stones.

Furthermore, the building blocks should serve as molds for certain Take over concrete fillings as a supporting structure, while they are not used for support themselves. Hence they no longer need to be made of stable material, but can now be formed from lightweight, synthetic or even foam materials will. This can result in structural weight and corresponding transport costs and equipment (cranes) can be saved. The weight of the building material is then almost entirely dependent on the weight of the (in the liquid state ζ B concrete that can be transported and filled in via a hose line depends on its casting cross-sections in the casting molds to be designed variably as required (e.g. for lower and upper floors).

Since the building blocks of low density, they can] be much larger in stature than today. Skilled workers are not or not absolutely necessary for their processing. Now, for the building blocks that have become the mold of the supporting structure, materials with desired technological properties can be selected for other advantages, such as elasticity, any precise formability for form fit and joint tightness, adhesiveness and finally heat and sound insulation.

Such modules are easy to rework, adapt and to slit and join for all installation lines in the walls, so that they are cost-saving, structure-borne noise and can be laid in a heat-insulated manner. Such soundproofing measures of the active type are usually cheaper and more effective than those of the passive type.

For the strength of the concrete fillings, their steel reinforcement is an advantage. The shape of the building blocks enables and facilitates their practical and variable insertion and favors the "shaking" and disintegration of the poured concrete

The steel wires (3) can thus be held in any appropriate direction. They can be as high as one storey, so that they are flush with the reinforced concrete; ceilings can be cast in a forceful manner to reduce the length of the knees. The openings can be connected by transverse grooves (5), which are also filled with concrete when pouring, which surrounds the inserted steel reinforcement (6), which runs through several blocks. If necessary, the building blocks can be glued to one another for the sake of tightness, if necessary with a double-layer adhesive film.

Of course, since u V still easily transportable, much larger standard dimensions (Figure 2) of the building blocks are possible without or in structural strength losing steel reinforcement.

Plastering a building shell with liquid mortar is very profitable, water and time consuming. The plate drying technique instead of plastering the walls from the inside is wage and space consuming.

By choosing appropriate materials for building blocks, their dimensioning No plastering of the masonry is required for heat and sound insulation and its surface structure (density, smoothness, color) more, neither for the walls outwards nor inwards.
