Definitions
- the invention relates to a self-supporting composite building board, in particular raised floor slab with a rectangular plan and a flat trough, preferably made of sheet metal, as external reinforcement for a pourable and pourable state in the trough and cured therein with high pressure resistance, z.
- B. anhydrite with at least the tub base provided with numerous, the composite (anchoring) with the filling material producing punches and the tub bottom is also profiled.
- a self-supporting composite building board of the above type the outer trough-shaped reinforcement of which, however, has a flat bottom
- DE-PS 2 004 101 or EP-A-0152609
- Further developments of this composite building board are already known (cf. brochure of the company MERO-Werke “MERO-Doppelboden” D 488 2/79), in which the bottom, the sheet metal tub serving as external reinforcement, has radially extending beads from the center outwards , which merge into a surround surrounding the edge of the tub floor.
- the tub floor was arched from the outer edges towards the center of the floor. This means that the filler material, e.g. B.
- the invention has for its object to provide a cantilever composite panel, in particular raised floor slab with higher load capacity compared to the prior art, while maintaining the previous plate height and material thickness for the tub-shaped outer reinforcement.
- the above object is achieved with a self-supporting composite building board of the type described in the introduction in that the trough bottom has four essentially cruciformly arranged, flat-arched zones, each of which extends from deep areas in the center of the floor and along the cruciform axis of symmetry of the trough to the highest Extend the area next to each bath corner.
- Embodiments of the invention emerge from the subclaims. It is Z. B. useful if the apex lines rising outwards against the tub corners of the four curved zones coincide with the diagonals of the tub.
- a flat, plate-shaped elevation is provided in the middle of the tub floor, the height of which, measured from the deep areas of the tub floor along the axes of symmetry of the tub, is only a fraction of the greatest height of the tub floor in the areas next to the tub corners, An undesirable snap effect is avoided due to tensions in the tub floor, which can be created when the four flat, domed zones are formed.
- the greatest height of the arched tub floor in the areas next to the tub corners is expediently one fourth to one fifth of the overall height of the tub.
- the degree of deformation of the tub floor is thereby advantageous kept relatively small. This is not only favorable in terms of production technology, but also with regard to the material thicknesses of the tub base after the deformation process.
- a peripheral bead with a flat bottom is formed in a manner known per se in the edge region of the tub bottom next to the side walls of the tub, the level of which runs somewhat below the deepest areas between the four curved zones of the tub bottom, one is advantageous Touching the profiled trough floor within the surrounding bead with a raw floor or the like.
- the tub (10) chosen as the exemplary embodiment consists of deep-drawn steel sheet galvanized on both sides and forms the outer reinforcement for a filler material (11), preferably anhydrite, which is introduced in the flowable state and hardened in the tub (10), around a raised access floor panel (12) (Fig. 5) with a square floor plan.
- a filler material preferably anhydrite
- These raised access floor panels (12) have a covering (13) and are supported with their corners on footrests (14) so that the outer edges of the raised access floor panels (12) touch.
- the footrests (14) are in turn set up on a bare floor (15).
- the sheet steel pan (10) has z. B. a side length of about 600 mm and is with a height of z. B. approx. 33 mm relatively flat.
- the steel sheet trough (10) has a specially profiled floor (16) from which the four side walls (17) extend upwards in order to increase the load-bearing capacity or resilience of the raised floor plate (12).
- the upper edge of these side walls (17) is designed as an outwardly angled flange (18).
- the edge area of the tub floor (16) contains a uniformly deep and wide surrounding bead (19) with a flat bottom. Only at the four corners of the tub (10) is the bead (19) at (20) widened inward and provided with a flat angular recess (21) with which the tub (10) on the Footrests (14) (Fig. 5) is supported. Within this circumferential bead (19), the trough base (16) is provided with four flat, domed zones (22) and a flat, plate-shaped elevation (23) in the center of the base.
- the four arched bottom zones (22) are arranged symmetrically in such a way that they each extend from deep areas along the cruciform symmetry axes (24) of the tub (10) and from the flat plate-shaped elevation (23) in the middle of the tub bottom to a highest area (25). Extend next to each tub corner, the apex lines of the arched zones (22) rising outwards against the tub corners coinciding with the diagonals (26) of the tub (10). As can be seen in particular from FIG. 4, the height of the plate-shaped central elevation (23) is only about half the greatest height of the tub floor (16) in the areas (25) next to the tub corners.
- the same figure also shows that the greatest height of the tub floor (16) in the areas (25) is only about a quarter to a fifth of the overall height of the tub (10).
- the distribution of the punches (27) in the tub floor (16) is also important for the high load-bearing capacity or resilience of the finished raised floor plate (12).
- the density of the punches (27) is lowest in the middle of the trough bottom in the area of the plate-shaped elevation (23), while their concentration is greatest at the edges of the trough bottom (16) compared to the surrounding bead (19) or the side walls (17) .
- a series of closely adjacent punches (27) is provided here. In deviation from the exemplary embodiment, a plurality of rows of closely adjacent punches (27) running parallel to one another can also be arranged. It is essential that the density of the punches (27) increases from the center of the tub bottom to the outside.
- the punches (27) can also be arranged regularly or irregularly in the tub floor (16).
- the preferred filler material (11) is anhydrite
- other flowable or pourable and hardenable materials e.g. B. concrete
