Definitions
- the invention relates to a plasterboard element for a wall / ceiling substructure, which is a one-piece plasterboard, a visible side and forms a back and has two longitudinal edges, the mutually asymmetrical, interlocking engagement / rear grip designs as an assembly aid with a visible or rear projection have, and in which each edge - seen in cross section - starting from the visible side a laterally crossing longitudinal edge course to the back, which is uniformly aligned at 40 ° to 60 ° is inclined to the central plane of the plate.
- Gypsum board element consists of two one-piece glued together flat encased plasterboard 101, 102, each half-rounded board edges form and are laterally offset from each other.
- the plasterboard element thus forms edge-side edges 103, 104, which are designed step-like are, in each case one plasterboard protrudes around a projection 105. Due to the rounding of the board edges, the plasterboard element shows both on a visible side 106 and on a rear side 107 at the edges 103, 104 each have a spatula 108, which with the spatula one abutting plasterboard element forms a spatula groove 109 which with a Filler is filled.
- the spatula is - seen in cross section - semi-circular / inclined to a plate center plane 110 and the two Filling chamfers of a spatula groove are symmetrical and exactly the same size.
- the plasterboard element by means of two rows of fastening screws 112 on the edge attached to a substructure 113, one of which is a slat in FIG. 5 trained substructure strut is shown.
- the mounting direction of the Gypsum board elements are indicated by an arrow 114.
- Gypsum board elements of the type mentioned at the beginning are considered so-called one-man boards, since they can be assembled by only one man, the engagement / rear grip designs serve as an assembly aid.
- One man can namely hold the one plasterboard element with the rear projection one edge behind the visible projection of an already assembled one Slide plasterboard element and the other edge of the held plasterboard element with a fastening screw on the substructure fix. Then the plasterboard element is close to the edges on the edge and along other lines using a variety of mounting screws attached to the substructure.
- the plasterboard element of the The type mentioned at the beginning thus serves to form a wall or ceiling shell on the substructure.
- the width of the gypsum board element For a given thickness of the gypsum board element, its width is or span is limited, e.g. currently 62 cm to 80 cm. If you look at the gypsum board element with otherwise the same design, a larger one Span there, then the deflection of the plasterboard element increases in the assembled state between the adjacent substructure struts. With substructure struts are stands, slats, Rafters or metal profiles. The plasterboard elements hang by. This deflection occurs on ceiling cladding and false ceilings particularly striking in appearance. The substructure must therefore be geared towards relatively small spans. For wall / ceiling substructures there is therefore a relatively large number of substructure struts.
- each edge has a spatula on the visible side to define a panel joint filler groove, the fillet chamfer are arranged obliquely relative to a spatula center plane, and that the spatula - seen in cross section - an obliquely arranged Truncation of one acute-angled projection is, and the other Spatial bevel - seen in cross section - a slight bend in one edge is obtuse.
- the plasterboard element according to the invention is also with an enlarged span or width in the fully assembled state without bending or Sag.
- the struts the substructure into which the fastening screws are driven can accordingly be further apart, so that less Substructure struts and fewer rows of fastening screws required are.
- the total thickness of the gypsum board element according to the invention not larger than that of the well-known two-plate composite. It can be stated that, with the same overall thickness, the deflection strength a one-piece plasterboard is considerably better than that of a two-gypsum board composite.
- one-piece plasterboard with the well-known step-like engagement / rear grip designs not manufacture because this, as far as it is at all is technically feasible, is not economically feasible. That's why she sees Invention in accomplishing the task as engagement / rear grip designs the obliquely inclined longitudinal edge course, which is at a one-piece gypsum board can be produced economically.
- the angle range 40 - 60 ° is the effect of the acute-angled projection guaranteed as an assembly aid. Because of the trowel blunting the danger to be observed with plasterboard reduces that a point of the acute-angled projection breaks off.
- the thickness of the one-piece plasterboard in practice will be at least 18 mm and usually amount to a maximum of 25 mm.
- the spatula goes on Projection under a strong, reversing bend in the inclined slope Longitudinal edge course over and goes the spatula on the the projection opposite side over a slight bend in the obliquely inclined Longitudinal edge course over.
- Two adjacent to the substructure one-piece plasterboard panels pushed against each other touch each other the sloping longitudinal edge course.
- These two gypsum boards are not glued together and do not have to be glued together his.
- the two filler chamfers of a filler groove offer the filler not the same areas. Within the scope of the invention, that the two spatula chamfers of the spatula groove are exactly the same size.
- the gypsum board element according to the invention are therefore also essentially the design of the spatula chamfer delimiting the spatula groove.
- the dimension the one with the spatula chamfers and the obliquely inclined longitudinal edges provided edges is usually a multiple of the span of the one-piece Gypsum wallboard.
- flushing trowel groove is used subsequent obliquely inclined longitudinal edge course itself extends at least 1/3 of the thickness of the one-piece plasterboard. Then the obliquely inclined longitudinal edge is long enough to slide against each other Forces occurring in adjacent plasterboard elements record without damage.
- the invention also relates to a gypsum board element at the beginning mentioned type that with an adjacent plasterboard element on the Wall / ceiling substructure is brought together, the longitudinal edges of the two plasterboard elements are pushed against each other and the two spatula chamfers forming the spatula groove from each other to have.
- the two one-piece plasterboard only, i.e. not with the spatulas, along the obliquely inclined longitudinal edge course collided and the two spatula chamfers of the spatula groove are designed differently.
- the Invention thus achieves the object by not just supporting the two plasterboards against each other in the middle assigns the edges arranged obliquely inclined longitudinal edge courses alone, but also goes over to spatulas that differ in the course are designed.
- the protrusion Due to the angular range 40 - 50 ° of the continuously rectified, the protrusion is relatively short or stocky.
- the conditions are set up so that the inclined Longitudinal edge course in one between the visible side and the Back extending diagonal line lies one in the plate center plane lying longitudinal section, which is 0.75 - 1.25 times the Thickness of the one-piece plasterboard is. It is the present arrangement not about the diagonally inclined longitudinal edges of the two Edges to create the largest possible contact surface, but only about making the contour of the edges easy to manufacture. Also because of the limited (e.g. 1 m) span of the plasterboard the dimensions of the engagement / rear grip designs running in the direction of the plate center plane keep small; the engagement / grip design should only affect a relatively small proportion of the width of the Extend plasterboard.
- the plasterboard element according to the invention usually has on the visible side near the two longitudinal edges one with a flat provided edge area, with the flattening towards the spatula groove gets deeper. This flattening improves the leveling and leaves the inlay of a joint tape.
- the invention Gypsum board element also on the back spatula joints to form Filler grooves, although there is no filling on the back.
- one-piece plasterboard also allows the both edges on the obliquely inclined longitudinal edge course to Back side are butt-shaped to match. At this Training arises when two are placed side by side or put together one-piece plasterboard with no spatula groove on the back.
- the design of the plasterboard element according to the invention can e.g. provide for a gypsum fibreboard, the total surface of which Gypsum material is formed. Another embodiment of the invention lies before if one extends to the visible side, the back and the edges Sheathing is provided, the surface of the plasterboard element overall is essentially formed by the casing.
- the difficulties with regard to span and implementation lie with the known one Gypsum board element particularly pronounced when the gypsum building boards are covered because these gypsum building boards primarily have their flexural strength get from the casing and the casing for improvement the flexural strength is difficult to influence.
- the casing is e.g. a glass fiber material, but is usually cardboard, so called Plasterboard is available. It is encased for the invention to produce one-piece plasterboard, the sheathing on the two Edges bent or kinked differently. So is the casing only slightly bent at one edge in order to form the spatula on the other edge very distinctly bent and kinked to the projection to consider.
- the plasterboard element is a one-piece plasterboard 1, in which a core 2 made of plaster material is provided with a casing 3 is.
- the plasterboard has a visible side 4, a rear side 5 and two longitudinal edges 6, 7.
- the casing 3 consists of one Part that is on the visible side 4 and the edges 6, 7 and with cover strips extends to the back 5 and a part that the back 5 and covers the envelope strips.
- the gypsum building board 1 is a board center plane 8 assigned and the plasterboard 1 forms with two adjacent plasterboard 9, 10 a wall or ceiling.
- the plasterboard 1 is attached to a substructure 11, of which only one substructure strut are shown, which are transverse to the plasterboard 9, 1 or 1, 10 is located on the back. There are rows of mounting screws 12 through the plasterboard 1, 9, 10 into the struts of the substructure 11 driven.
- the obliquely inclined longitudinal edge course 13 lies in a theoretical diagonal line 20, which together with the visible side 4 or the rear side 5 Give projection 19 an acute-angled configuration; the projection is 19 blunted by the strongly curved or kinked spatula 15.
- the Plasterboard has a thickness 21.
- the diagonal line 20 intersects the Visible side 4 and the rear side 5 and thereby determines one in the middle plane 8 lying longitudinal section 22.
- the direction of assembly of the plasterboard 1, 9, 10 is given by an arrow 23.
- the substructure 11 is of vertical struts formed in the form of metal profile stands.
- the substructure 11 is on both sides with a wall shell made of plasterboard 1 provided, which are attached by means of the fastening screws 12.
- the substructure 11 is inclined inclined struts formed in the form of rafters of a roof.
- the substructure 11 is only on one side, namely on the underside a ceiling shell made of plasterboard 1, which by means of Fastening screws 12 are attached.
