DE814520C - Scarf stone for window and door lintels, underlay and like - Google Patents

Description

The subject of the application is a formwork stone for window and door lintels and the like. Made of concrete or reinforced concrete.

For bridging wall openings such as windows and doors and as Beams or the like are sometimes finished and form-fitting, the entire span bridging components inserted, or one manufactures one to be removed afterwards Formwork on, which is stamped with concrete. Come with newer construction methods more and more so-called scarf stones in use. The production of heavy beams or Window and door lintels in the factory, transport to the construction site and insertion in the masonry are still too expensive and time-consuming today with quick construction methods, and in many cases a so-called grown bond with neighboring components cannot be achieved. Scarf stones, wreath stones and similar components can be used however, easier to insert into the building, they only require lighter auxiliary support and allow continuous building. As the word Schalstein says, these are the ones Formwork and cladding of the load-bearing and bridging parts to be subsequently tamped down Concrete core. The caped scarf stones, for example for window lintels, hang, since they are smaller than the window span, at the core and require special Attachment and connection with this, otherwise they would tip over. You are therefore Only to be used with limited span and it is to be used on beams of larger span not to think about this.

These disadvantages are intended to be remedied by the scarf block according to the invention which is illustrated in the drawing, for example, in cross-sections.

Fig. I shows the formwork stone divided into the lower stone a with bulge b and projection c and the upper stone d with the injection opening e and outlet f , into which the neighboring component i, in this case fused with the concrete core h, protrudes; , Fig. 2 shows the basic form of the formwork stone used for beams; Fig. 3 when used as a lintel and at the same time in a horizontal core composite with a neighboring component i.

The basic size of this scarf block is adapted to the standardized dimensions and can be lined up in a large number of rows and installed in a grown bond with any neighboring components; with simple help. The organically attached bracket, in the example in the drawing of the bead b, ensures the clasping hold with the load-bearing concrete core h. Even with a large span, the hanging block cannot tip over and become detached from the structure. In the case of a small span and a low construction height, the lower stone a with bead b is sufficient; in the case of a larger span, a greater load-bearing capacity and construction height is achieved by impacting the upper stone d. If a subsequent concrete ceiling or support structure is attached, it is advisable to use the upper stone d in the version with an opening f, which can extend over the entire length or only forms partial sections.
