Abstract

Re floor brick; this square, loadbearing perforated brick for the fabrication of reinforced-block floors is suitable for everything from a cost-effective production at the brick works to the mechanical fabrication of the floor with a smooth lower layer which can be painted and wallpapered. In this arrangement, the floor brick can be advantageously used not only for the prefabricated brick floor panels but also for mechanical laying and grouting directly in the structure. Re the step brick: this extruded perforated brick profiled in the shape of a step is loadbearing and configured for the cost-effective fabrication of steps, which are either prefabricated or built directly into the structure. Mechanical production of the step bricks in the brick works requires only a small amount of additional equipment. With this floor brick and the step brick, a smooth lower layer which can be painted or wallpapered is achieved for floors and steps in the erection of the structure in one operation, with the result that painstaking plastering on the building site is thus replaced in an equivalent and simple manner.

Description

Ceiling and step tiles

The invention relates to a manufactured in the extrusion process, statically active perforated brick for the production of steel stone ceilings, reinforced concrete rib ceilings and straight stairs.

The ceiling tiles detailed in DIN 4159 have in Cross-section of a widening of the base area on both sides; also in longitudinal section these ceiling tiles have a widening of the base area, optionally one or both sides. According to the German patent application no.

P 33 07 717.7 is this brick foot in the step brick from the DIN 4159 adopted.

There is only one required to manufacture these ceiling and stair step tiles very small part of the built-in brick cutters can be used and when cutting these briquettes must be a significant proportion of the molded clay strand of the extruder to be led back; in terms of space, the drying systems are considerably less used and the large free cross-sections between the briquettes impair the drying process unfavorable; small existing mechanical setting device is suitable for these briquettes to put.

The underside of the structural component, whether ceiling or stairs, must have a Plaster are provided following, the application of which is complex.

The object of this invention is to provide a ceiling tile and a step tile to create that is easy to manufacture, with the existing and existing Setting machines can be set and used in the erection of ceilings and stairs in one operation with an additional work fabric a smooth one The underside, ready for painting or wallpapering, has, as well as the building physics Meets requirements while bringing about the great advantages of the brick of a healthy living environment.

The object is achieved according to the invention, the moldings for a ceiling or stair step tile from an extruder and die with rectangular cross-section, laterally corrugated, according to Fig. 1, 3 respectively. 6 and 2, 4, 5 or 7 can be automatically cut in the longitudinal view.

1 and 2, 6 and 7 show bricks with fully mortared butt joints; FIG. 3 with a butt joint that can be partially mortared, the longitudinal view of FIG both sides, and FIG. 5 shows the one-sided butt joint recess.

The shape and arrangement of the holes are arbitrary.

A plate (1), FIG. 8, advantageously serves as the ceiling and staircase soffit large format, with a non-slip top (2) to provide the necessary adhesive bond to allow the mortar (3) to be introduced during production, a smooth one Bottom (4) to accommodate the ceiling wallpaper or paint, as well as avoidance a different color between the brick and mortar surfaces, which otherwise arise from different physical properties. This plate (1) should in terms of building physics with regard to thermal conductivity and water vapor diffusion values own that are very similar to brick; in terms of fire resistance and durability, this is manufacturing technology in the relevant industry just as workable. Thin wood fiber and chipboard, for example, meet these requirements.

When creating stairs on the spot, be accordingly the stair incline and tread width, small stops (5) on the top of the slab for the step brick (6), as shown in Fig. 9 shown is. These stops (5) can also act as supports for the longitudinal reinforcement (7) to be brought in between the individual rows of stairs and mortared are, serve. Compared to this training of the step brick according to the German Patent application Fr. P 33 07 717.7 the bricks used for installation are very allowed have large tolerances, with an exact job and the required accuracy the completed raw staircase is reached in the same way.

Instead of the non-slip top of the plate (2), dowels can be used at intervals Find various types of use that are to be introduced between the bricks local ribs (3) protrude and hold the plate (1) firmly in the structure.

Instead of the thin plate (1), a thick insulation plate can be used will.

The technical advance of this invention is that the Production of the ceiling and step tiles is much easier, the ceiling tiles for material conveyance for mechanical-automatic laying on the construction site suitable according to their external shape and the underside of the ceilings and stairs have smooth surfaces and thus the workload of plastering is eliminated.

Fig. 8 shows the cross section of a fully mortared ceiling with the smooth soffit, according to this invention.

Fig. 9 shows the cross section of a straight staircase with the smooth one Bottom view, according to this invention.

Claims (4)

Claims 1. Ceiling and step tile, characterized in that that the briquettes are produced in the extrusion process with a rectangular cross-section will. A plate (1), advantageously large in size, serves as the ceiling and staircase soffit with a non-slip top (2) to create the necessary adhesive bond with the during manufacture to be applied mortar (3) to obtain a smooth underside (4) to the ceiling wallpaper or to take up the paint, as well as avoiding a different parbe between the brick and mortar surfaces in the finished component. 2. Step brick according to claim 1, characterized in that Small stops (5) on the according to the stair incline and tread width The top of the plate for the step tile (6) must be attached. 3. Ceiling and step brick according to claim 1, characterized in that that instead of the non-slip top side of the plate (2), dowels are used at intervals, which protrude into the mortar ribs (3) to be introduced between the bricks and these Connect the plate to the structure with a force-fit connection. 4. Ceiling and step brick according to claim 1, characterized in that that instead of the thin underside plate (1) a thick insulation plate is used will.
