Definitions

  • the present invention relates to a lintel for supporting one or more wall layers when masonrying buildings, such as bridging wall openings, supporting brick facades and the like, and which consists of a relatively thin, angled sheet metal profile with at least two legs.
  • Wall lintels for bridging wall openings are known in many different designs (DE-A-1,966,687, 2,533,856).
  • GB-A-1457803 proposes a hollow beam that is walled in behind the facade and has a considerable height.
  • So-called light beams are also known (BE-A-489.891) which are provided with perforations-holes in a module system and allow several beams to be screwed together to form a beam system.
  • Lintels have also already been proposed (GB-A-598.093) which bridge both the facade wall and the backing via window or door openings and which lintels protrude with a roof-shaped part into the space between the two walls.
  • the purpose of the invention is to propose a lintel of the type mentioned at the outset, which has sufficient strength to support the wall layer, which is light in weight and has little influence on the loading conditions due to its own weight, which absorb torsional forces caused by one-sided loading of the lintel during the walling can, and which can be added from a thin sheet profile in a simple manner.
  • the invention is based on the object of creating a wall lintel of this type which, despite its lightweight construction, can absorb large loads during masonry work, but after the mortar has set, is not an obstacle in the way between the bricks when setting a window or door frame.
  • the load-bearing leg of the fall forming the web of the lintel is each provided with a material weakening extending over its entire length, for example a series of slits perforations or the like, the material weakening the web in two parts divides, of which the outer part - after the masonry has received load-bearing capacity - can be broken inwards or broken off at a distance from the edge to the second leg approximately corresponding to the thickness of a wall joint.
  • the lintel 1 according to the invention according to FIGS. 1-3 is mainly Z-shaped in cross section, one leg 2 consisting of two parts 2 and 3 which are at an angle to one another and have the shape of an inverted V in cross section.
  • the angle between the central part 4 of the Z-shaped profile and the mentioned first leg 2 is somewhat greater than 90 °, so that when the central part 4 assumes a horizontal position, it is inclined upwards and outwards, that Part 3 of the inclined leg 2 mainly forms a right angle with the horizontal central part 4, which can be brought to bear against a building.
  • the second leg 5 of the Z-shaped sheet metal profile is mainly bent at right angles to the central part 4 and serves as a load-bearing stiffening web during the mooring and until the masonry has received its own strength to be self-supporting.
  • the leg 5 is provided with material weakenings 6 along its entire length.
  • these material weakenings consist of slot-shaped openings with narrow material parts between the individual slots, which are arranged in a row at a distance from the bending edge, which expediently corresponds to the thickness of a wall joint.
  • the weakening of material in the leg 5 is arranged such that the load-bearing capacity of the leg is only insignificantly reduced in its plane.
  • Other types of material weakenings than slots or perforations are also possible, for example cracks, grooves or combinations of the measures mentioned.
  • the section of the leg 5, which extends from its free end edge to the material weakening 6, can either be bent in the direction towards the central part 4 of the lintel or this section can also be bent by repeated bending along the material weakening 6 be canceled.
  • the remaining part of the leg 5 can serve as a drip nose.
  • the free end edge of the leg 5 is bent through 180 °, as can be seen in FIG. 1.
  • the horizontal middle part 4 of the lintel 1 is provided on the side facing away from the leg 5 with a punch 7, through which a tongue 8 is formed, which is separated on three sides by the punch from the middle part.
  • the tongue 8 is normally in the same plane as the central part 4 and can be bent downward by about 90 ° and thereby forms a support so that the rear edge of the lintel cannot be inclined due to the load on the bricks in the soft mortar.
  • tensioning straps 11 which are connected to the legs 2 and 5 in such a way that a load can be transferred.
  • the tensioning straps are attached between the butt joints of the bricks and consist of a plate or the like.
  • the ends are provided with bends 23, 24 which can be inserted partly into the slots 6 of the leg 5 and partly bent over the free end edge of the leg 2 can be.
  • the lintel shown in FIGS. 1-3 is intended for bridging openings first, but in addition to its function as such it also has to serve as a water drain for which water runs off at the back of a facade covering or the like.
  • the lintel shown in FIGS. 1-3 cannot be used because the leg 2 cannot be accommodated and should also not be visible.
  • the lintel 9 shown in FIGS. 4 and 5 can be used, which is mainly U-shaped and can be used wherever the underside of the wall opening is covered by, for example, a window or door frame.
  • the legs 12, 13 are designed with a relatively large web height, which absorb most of the loads that occur. Material weaknesses 6 are provided in both legs 12, 13 at some distance from the bevel edge.
  • the leg sections 12, 13 are removed in accordance with the length of the support surface until the material is weakened, as is illustrated, for example, in FIG. 5.
  • the parts of the legs that extend into the wall opening remain intact during the brickwork until the mortar has set, thereby absorbing the fall from one or more layers of stone.
  • the outer sections of the legs 12, 31 can be broken off until the material weakening 6 by repeated back and forth, as in FIG. 5, right part of the figure Figure is shown. In this training, the fall can possibly be covered with mortar.
  • the exemplary embodiment according to FIGS. 6 and 7 shows a lintel 16 which is used where the masonry structure is not self-supporting and can only be achieved by reinforcement or the like.
  • the lintel 16 consists of a mainly U-shaped sheet metal profile which is formed in the middle part 17 between the legs 19 and 20 with a roof-shaped part 18 running in the longitudinal direction of the lintel. Near the bend edges are material again. weakenings 6 are provided, the slots in the roof-shaped part 18 are provided in the immediate vicinity of the bend, while the slots in the legs 19 and 20 are spaced apart by approximately a wall joint.
  • the roof-shaped part 18 is introduced into a recess 21 in the bricks which form the first layer, the remaining cavity of the recess 21 being filled with mortar or the like. As soon as the masonry has received sufficient load-bearing capacity, either only the legs 19 and 20 can be broken off or broken along their material weaknesses 6 or the legs 19, 20 together with the middle parts 17 on both sides of the roof-shaped part 18 can be broken off along the slots 6.
  • This type of reinforcement 18 is particularly expedient for large-volume stones, such as, for example, aerated concrete blocks, light-clinker blocks, concrete blocks, concrete hollow blocks, etc.
  • the lintels according to the invention consist of relatively thin steel sheet (for example 0.7-1.0 mm thick), but it is also possible to produce the lintels from so-called expanded metal, the material weakening being achieved by means of cracks or grooves.
