Definitions

  • the present invention relates to a roller shutter box with a substantially U-shaped Cross section and consisting of brick material, the roller shutter box from one is made of one-piece hollow brick and its legs forming the U-profile and the crossbar connecting them have hollow chambers.
  • the present also applies Invention also a method for producing a roller shutter box from brick material, wherein the malleable brick clay material in the desired cross-sectional shape of the roller shutter box is extruded.
  • a corresponding device and a corresponding method are known from DE 35 43 828 A1.
  • roller shutter boxes made of brick material are known.
  • the two the latter documents are used for the manufacture of corresponding roller shutter boxes on the front Form stones coated with binder are placed next to each other and e.g. with several in Reinforcements in the longitudinal direction and a binding agent to form a rigid Roller shutter box connected.
  • roller shutter boxes produced in this way are relatively complex and expensive. Furthermore the known roller shutter boxes made of brick material often only have poor thermal insulation properties on. In order to make the frontal gluing sufficiently durable, the Glue area become correspondingly large, which in turn correspondingly large wall thicknesses required and at most allows small void cross sections in the bricks. This is however with a view to a higher thermal conductivity and thus worse Thermal insulation disadvantageous.
  • roller shutter boxes made of brick material basically have the positive property that they are in terms of their surface and also in terms of their Coefficient of thermal expansion with the brick material from which house walls usually exist, largely agree, that is, they form with the House walls homogeneous plaster base, which affects the durability and adherence of a Plaster layer and in terms of avoiding plaster cracks has a positive effect.
  • the object of the present invention is to create a roller shutter box and a method for its production, which not only is available in a desired length without being assembled from several pieces to have, but which also above all, further improved thermal insulation properties Has.
  • this object is achieved in that the length of the Hollow brick is at least 90 cm and that at least the horizontally running walls of the hollow chambers including their horizontally running partitions Have a wall thickness of less than 12 mm.
  • the object underlying the invention is achieved in that the cavities provided in the roller shutter box are extruded with a minimum cross section of 22 x 60 mm 2 and the roller shutter box is extruded to a length of at least 90 cm.
  • roller shutter boxes produced according to the invention Due to the narrow design of the horizontal walls, which the individual hollow chambers of the Limit roller shutter and are due to the relatively large cross sections of the individual hollow chambers the thermal insulation properties of the roller shutter boxes produced according to the invention the well-known roller shutter boxes made of brick clay material significantly improved again.
  • the size The length of the roller shutter boxes according to the invention enables the usual window and door widths to bridge with a single roller shutter box part.
  • Preferred embodiments of the invention are characterized in that the length of the one-piece brick material blocks at least 1.20 m, preferably at least 1.60 m is, where also one-piece brick blocks of over 2.50 m in length (specifically 2.60 ml in the Practice are feasible.
  • Such roller shutter boxes can therefore be in the right place from the start desired length can be delivered in one piece and do not require any further Processing before use on a construction site. So in particular you don't have to individual pieces assembled and glued and also not with reinforcing elements be shed.
  • the object on which the invention is based is therefore achieved in that the mouldable brick clay material is extruded to a minimum length of 90 cm by means of a corresponding matrix or compression mold, the cavities provided in the roller shutter box being produced with a minimum cross section of 22 x 60 mm 2 will.
  • the initially still box made of brick material is expediently picked up by a conveying device and transported as stress-free as possible according to the extrusion speed.
  • the walls forming the U-profile ie two walls each forming a U-leg and the crossbar connecting hollow chambers on.
  • Such hollow chambers improve the thermal insulation properties of the roller shutter box. Since none because of the one-piece design of the roller shutter box according to the invention end-face gluing of shaped blocks are more required, must also for one Bonding required cross-sectional areas no longer exist, so that Hollow chamber cross sections, based on the total cross section of the roller shutter box can have a significantly larger share of the total cross-section of the roller shutter box.
  • embodiments of the invention are preferred in which at least one of the two legs of the U-profile, namely that when installing the inside of a building facing leg, but preferably also the outer leg and the crossbar have on average a void fraction that is at least 50% of the total cross-sectional area of the leg or crossbar. In particularly preferred variants this cross-sectional area proportion of the cavities even in the order of about 60% and above. It is already preferred due to the method of manufacture if the Roller shutter boxes manufactured as hollow chamber profiles with a constant profile cross-section become. The cross-sectional relationships and thus also the thermal conductivity properties are then the same everywhere perpendicular to the longitudinal direction of the roller shutter box. The favorable cross-sectional ratio reached from cavity cross-section to the cross-section of the brick material itself one by the walls of the hollow chambers towards the outside, but especially also the Partitions of the hollow chambers have a correspondingly small wall thickness.
  • Embodiments of the invention are therefore preferred, in which in particular the horizontal walls of the hollow chambers, i.e. the partitions in the vertical running U-legs and those on the outside of the U-profile and on the inside of the U-profile adjacent walls of the hollow chambers of the crossbar a maximum wall thickness less than 10 mm and particularly preferably less than 8 mm.
  • wall thicknesses down to 5 mm have already been realized.
  • the main thing is that the walls that run horizontally and therefore Thermal bridges from the outside of the roller shutter box towards the inside form. Nevertheless, the wall thicknesses of the vertical walls of the Hollow chambers do not exceed a dimension of 12 mm, preferably 10 mm.
  • the hollow chambers should have the same cross-section as far as possible, but at least have a cross-sectional area that is essentially the same in amount.
  • thermal insulation material preferably foamed with PU foam.
  • too constant profile cross-section and the same cross-sectional areas of the cavities as extremely cheap, because then the PU foam from a cavity corresponding Number of tubes or nozzles that can be inserted into the cavities with constant filling rate can be filled, the tubes or nozzles in all cavities with the withdrawn at the same speed, while at the same time from all tubes the same Quantity of PU foam or other thermal insulation material emerges. Because the cavities Amount in roughly the same cross-sectional areas and thus an identical overall With such a procedure, all cavities are filled evenly.
  • the total wall thickness of the legs of the U-profile should be at most 50 mm, but preferably less than 40 mm, for example 38 mm, the internal dimension of the hollow chambers of the legs in the thickness direction of the legs being at least 24 mm, preferably at least 26 to 28 mm.
  • the external dimensions of the roller shutter box correspond to the usual requirements and standards for all common types of masonry and are, for example, 300 x 300 mm 2 in cross-section or even more, for example 300 x 365 mm 2 , with a clear internal dimension between the legs of at least 200 to 225 mm and a slightly larger clear height from the inner base of the U-profile to the plane defined by the leg ends.
  • the free end faces of the two U-legs, which face away from the crossbar of the U-profile are preferably have a groove for inserting reinforcing material, preferably in Connection with an aluminum rail, which serves as a plaster, plaster edge or corner rail.
  • the Reinforcement may be necessary, for example, if the roller shutter box before a Fall has to carry larger loads or if excess lengths, e.g. 3 m or more, two Roller shutter boxes according to the invention must be connected to each other.
  • the roller shutter box Despite the relatively small wall thicknesses and the relatively large proportion of the cavities on Total cross section of the U-legs and the crossbar is the roller shutter box from completely sufficient stability and can easily the conventional, made of shaped bricks Replace composite roller shutter boxes also in static terms.
  • the roller shutter box itself is not a load-bearing structural element of a building, but carries loads at most until a lintel to be poured over the roller shutter box is finished or a appropriate carrier is installed. At the same time, the new roller shutter box is lighter and front all because of the reduced use of personnel in the production also cheaper.
  • the roller shutter box On the Top, i.e. on the outside of the crossbar of the U-profile, the roller shutter box has preferably at least one substantially groove-like concrete filling bag.
  • Preferably two such concrete filling pockets are provided, at least one of the walls of the groove-like concrete filling pockets one Undercut forms by facing the outer surface of the crossbar and opposite a perpendicular to this runs obliquely.
  • the walls should be two different Concrete filling pockets must be inclined in opposite directions, so that overall, after the hardening of the concrete material intervening in both concrete filling pockets Wedging effect of a dovetail connection results.
  • An advantage of these concrete filling bags also lies in avoiding an air gap that is otherwise, for example after the Hardening of the lintel, due to loads or load changes, through thermal Tensions, setting of the building etc. arise between the lintel and the roller shutter box can. Even if the roller shutter box is not firmly anchored to the lintel, it forms the part of the lintel part protruding into the concrete filling bag is at least a kind of labyrinth and prevents one Draft air gap.
  • the brick clay material is formed by a shape or matrix extruded, the outlet cross section of the extrusion die or matrix being the cross section of the Brick blank corresponds.
  • this matrix is not a flat one for the formation of cavities Molding can be, but for example mandrels or reaching up to the matrix opening or the like, which define the cavities created and around which the soft brick clay material is extruded.
  • shape or Matrix is also to be considered that the brick clay material continues to leak out the extrusion nozzle or matrix can still swell up, something that ultimately arises Wall thicknesses are therefore generally somewhat larger than those left free by the matrix Extrusion column.
  • the roller shutter boxes are to be produced by extrusion in such a way that the cross-sectional areas of the cavities are at least 22 ⁇ 60 mm 2 .

  • the crosspiece preferably also has only five or fewer hollow chambers, which is already from the demand for the same cross-sectional areas, based on the hollow chambers of the Thighs. Due to the usually arcuate shape corresponding to half a circular or U-bend curved inner surface of the crossbar results at least in the corner area, i.e. at the transition between the crosspiece and the legs, one that deviates from the rectangular shape Cross-sectional shape of the hollow chambers, if one is not excessively large in these areas Wants to provide wall thicknesses. Also behind the level of the outer surface of the crossbar recessed concrete backfill pockets may force one of a preferred one Rectangular shape, different cross-sectional shape of the cavities in the area of the crossbar.

  • This type of lintel formwork is a so-called "lost formwork", that is, after the Pouring with concrete and appropriate reinforcements remains made of brick material existing formwork installed and part of the lintel.
  • lost formwork you have through the use of brick clay material in turn a plaster base and homogeneous with the rest of the masonry due to the hollow chambers, an improved thermal insulation, because of that with a lot of reinforcing steel filled concrete lintel itself generally does not have good thermal insulation properties.
  • the lintel formwork according to the invention can be on one side only on the inside or outside or on both Sides, that is, be arranged in the extension of both legs of the roller shutter box.
