Description

Building board, especially for soundproofing and fire protection - patent application from 11.11.1968 patent application The invention relates to building panels for the construction of Room partitions, cladding, cladding and the like made from materials with low Strength.

Known building boards of this type have the following disadvantages: The edges of the panels are particularly prone to breakage, and edge damage occurs in particular on. Non-through-going screws, such as those used to connect the panels to one another or on skeletal parts are advantageously used because of the low The strength of the panel materials in these is not certain. Only non-through-going screws however, have the option of being viewed from the unseen or less important side and so on the opposite side a plate surface free of screw heads to obtain. hen both plate sides should remain free of screw heads, or Also for other reasons, the front sides of the panel are often provided with, for example, groove and Spring connections strung together. In these and similar cases it is advantageous to Slit the plate from the front side, e.g. by machining to be able to. In doing so, however, the ends of the board broke because of their poor strength or brittleness of the panel material.

Another disadvantage of panels without reinforcement or less expedient Reinforcement is their low fire resistance. Even if the panel material is fire-resistant in itself to a sufficient extent, blows of the occurring form Tension individual cracks that are sufficient to remove individual fragments from the panel structure fall out and the room seal required for fire protection is lost. This wall can be avoided by isolated skeletal division will. With a larger skeleton distance and / or correspondingly cheaper, thinner building panels and / or correspondingly higher fire loads, however, it occurs and demands Remedy.

Often the sound insulation of the known panels is also without reinforcement or unsatisfactory with unsatisfactory reinforcement and, in particular, lacking in fire-fighting Panels mostly on satisfactory sound insulation and sound-absorbing panels satisfactory fire resistance.

The object of the invention is daring to avoid such deficiencies, i.e. not continuous even with panels made of materials with low strength To make screw and / above groove connections applicable, Satisfactory fire resistance even with a wide skeleton, thin panels or high fire exposure to achieve and / or to increase the sound insulation of the panels.

As a solution, it is proposed for panels of the type mentioned at the beginning, that they have reinforcement at least in one edge zone.

Particularly advantageous refinements of the invention are set out in the subclaims laid down.

Embodiments of the invention are in conjunction below described with the drawing.

Building board, in particular for sound. and fire protection - patent application from 11.11.1968 Description of figures Fig. 1 bi. Fig. 8 shows the structural design of reinforcements or reinforcements in the edge zone and / or total area of building boards low strength, especially with plasterboard.

Figures 9 and 10 show such edge. or area reinforcement with mineral panels, e.g. with cement-bound asbestos fiber panels.

Fig. 11 shows an integral fire protection panel composed of 2 gypsum cardboard or asbestos fiber boards and one fire-retardant and heat-insulating Intermediate layer. The figures show in detail: Figure 1 by inserting a U-shaped The sheet metal profile can be screwed onto the plasterboard edge from two sides (i.e. a screwed-in self-tapping screw or self-tapping screw finds a firm hold). By inserting an L-shaped reinforcement profile, the edge is on one side screwable. When the edge profile is placed directly on the box a direct edge protection is created for the outer cardboard edges. Furthermore, the sharp-edged and straight design thanks to the inserted reinforcement profile the cardboard edges facilitated or secured during production. The reinforcement profile consists preferably of galvanized sheet steel or otherwise corrosion-protected Metal band.

Figure 2 Through the use of an essentially M-shaped 2α Edge reinforcement profile, the plasterboard can be screwed from two sides and also slidable, i.e. between the legs of the reinforcement profile subsequent sawing or milling or the like. A slot can be formed in such a way that a part of the plaster core remains next to the slot or that the entire space between the M-shaped legs to accommodate insertable Connecting springs or the like. Remains free.

The explanations apply mutatis mutandis to the reinforcement of the plasterboard to Figure 1.

Figure 3 The plasterboard edge is made by inserting a strip-shaped sheet metal profile screwable from two sides. Through punched and bent tabs in this sheet metal strip the spacing from the cardboard surfaces is effected during manufacture. The advantage of this design: the gypsum paste flows in spite of the production a laid reinforcement profile securely into the panel corners.

For building panels made of wood composite materials, e.g. for chipboard, which are pressed in the manufacturing process. can be sheet metal strips or similar Reinforced areas are also used without the bevels to maintain the spacing will.

Figure 4 Duroh insert of a U-shaped curved grid 12 b with preferably reinforced cross brackets 12 a, the plasterboard edge can be slit. In the aftermath inserting the slot or the slot made during manufacture after curing Slit can be inserted connecting means for connecting such during assembly Plates are placed one below the other. Advantage: gypsum paste flows safely into the Panel corners.

Pauplatte, especially for sound and fire protection - patent application vom 11.11.68 Description of the figures Figure 5 Gispakttonplatte reinforced in the whole area against breakage due to mechanical effects and / or heat effects, furthermore in the Edge zone reinforced with wire mesh, in the edge zone bent several times under certain circumstances. Due to the (3) U-shaped design of the grid reinforcement in the edge zone, the The edge of the plate can be slit and reinforced for inserting retractable fasteners. To keep the reinforcement grid at a distance from the cardboard surfaces during manufacture Parts of the reinforcement grid can be made corrugated (3 aj '.

Figure 6 Gypsum plasterboard reinforced over the entire area and in the edge zone bruise due to mechanical impact and / or heat stress. Through screwable Pieces of sheet metal, pressed into the reinforcement mesh or by edging with the reinforcement mesh connected, preferably arranged in the edge zone and / or in the total area The plasterboard is distributed modularly in the named areas screwable. (Sheet metal pieces 4) (spacer cams 3 b) Figure 7 plasterboard in the whole floor level and reinforced in the edge zone, bsr. reinforced by glass fibers (in loose pores, as fleece, mat, fabric, etc.). Glass fibers preferably with synthetic resin Impregnated, gypsum paste in the hand zone, preferably additionally tempered with resin, glass fiber reinforcement compacted in the edge zone or in several layers. (Fiberglass mat 7) Figure 8 plasterboard or asbestos fiber board or chipboard with heavy material filling, e.g. pebbles, Anhydrite grains, metal grains, etc. and / or> reinforced with split brick and complained. (Heavy body 6) Advantage: Increased sound insulation of the bedplate due to increased Weight due to heavy filling, but without increasing the bending stiffness of the plate.

Figure 9 Mineral-bound panels e.g. made of asbestos fibers, others mineral fibers, wood fibers, etc. in the total area and / or reinforced by hand by single or multi-layer wire mesh (7). Wire mesh preferably galvanized or Corrosion-resistant sheathed, straight during manufacture between the fiber layers pressed in, preferably between two or more pre-pressed individual layers inserted and during hardening or drying with the individual layers to form a sheet pressed and hardened or dried.

Figure 10 Mineral-bound panels, e.g. made of asbestos fibers, others reinforced with mineral fibers, wood fibers, etc. in the total area and / or in the edge with single or multi-layer glass fiber mats or fabrics, possibly also with synthetic resin soaked, in the edge zone preferably glass fiber reinforcement compacted or multi-layered and hardened and tempered by synthetic resin in such a way that the edge zone can be slit and / or screwable. (Glass fiber reinforcement 8) Building board, in particular for sound and fire protection - patent application dated 11/11/1968 Description of the figures Figure 11 integral fire protection plate, in particular as a fire-retardant intermediate part in multilayer partitions. 3-ply made up of two fire-retardant layers 9 (e.g. plasterboard or plasterboard GKF boards, asbestos fiber boards, flame-retardant Chipboard) and made of fire-retardant insulation mats or insulation boards (10) through nails (11); the nail ends are protected against tearing out by shims.

This means that there is a risk of parts of the plate breaking off as a result of the effects of heat reduced. Breaking off of plate parts due to the effect of heat is completely eliminated by additional wires or wire mesh stretched over the outside of the panel, or by wires that are cut between the nail ends.

Advantage: normal partition walls are made integral by gluing them in Fire protection panels between the outer wall panel shells in formal design for fire-retardant partition walls. Time-consuming individual installation of heat-insulating insulating mats and fire-retardant panels are omitted. By connecting spring 12 made of fire retardant Such integral fire protection panels can be made of non-combustible material get connected. The further advantage of this integral fire protection panel is in that in the zones particularly endangered for the passage of heat, t.b. in area of the floor, wall and ceiling connection between the outer connection profiles of the normally executed partition walls a fully-fledged fire protection component made of fire-retardant Sheets and insulating mats can be inserted.
