Definitions

  • the present invention relates to a lintel for supporting one or more layers of wall when masonrying buildings, such as bridging wall openings, carrying brick facades and the like is the load-bearing part of the fall.
  • Wall lintels for bridging wall openings are known in many different versions (DE-OS 1.966.687, 2.533.856).
  • lintels are sought which at least partly have space in the joint between two stone layers and are therefore made from a relatively thin sheet material.
  • the requirement for a low construction height means that the moment of inertia or the bending resistance is very high is small and the fall can only bear light loads.
  • tensioning straps or tie rods have been proposed (DE-OS 2,724,755) which are fastened to the leg end regions of the fall. By attaching these straps in the brick butt joints, they can be accommodated inconspicuously.
  • 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 therefore has little influence on the loading conditions due to its own weight, the torsional forces caused by one-sided loading of the lintel during the walling can accommodate, and which is bendable from a thin sheet metal profile in a simple manufacturing process without complex welding operations.
  • the invention is based on the object to create a wall lintel of this type which, despite its lightweight construction, can absorb large loads during masonry work, but after the mortar has set, it is not an obstacle in the way between the bricks.
  • the leg or legs each with one in its longitudinal direction extending material weakening, for example, a series of slots, perforations and / or one or more crevices, grooves and the like. Or combinations thereof is provided, the material weakening being designed so that the load capacity in the plane of the leg is only slightly reduced, while Material weakening at the same time forms a breakage indicator when the leg is bent along this.
  • material weakening for example, a series of slots, perforations and / or one or more crevices, grooves and the like. Or combinations thereof is provided, the material weakening being designed so that the load capacity in the plane of the leg is only slightly reduced, while Material weakening at the same time forms a breakage indicator when the leg is bent along this.
  • 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 at an angle to one another standing parts 2 and 3, which have the shape of an inverted V's 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.
  • the 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 masonry 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 weaknesses 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 suitably corresponds to the thickness of a wall joint.
  • the material weakening in the leg 5 is arranged so that the load-bearing capacity of the leg is only insignificantly reduced in its plane.
  • Other types of material weakening - as slits or perforations are 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 can be bent towards the central part 4 of the lintel or this section can also be broken off by repeated bending along the material weakening 6.
  • the remaining part of the leg 5 can serve as a drip nose.
  • the free end edge of the leg is bent through 180 °, as can be seen from 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 thus 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 Fig. 1-3 is intended for bridging openings at first hand, but in addition to its function as such it also has to serve as a water drain for the water at the Back of a facade covering or the like.
  • the lintel shown in FIGS. 1-3 cannot be used since the leg 2 cannot be accommodated and should not be visible either.
  • 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 bending 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. 2.
  • 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 the illustration 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.
  • Material weaknesses 6 are again provided in the vicinity of the bending edges, the slots in the roof-shaped part 18 being 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 l8 is particularly useful for large-volume stones, such as gas concrete blocks, light clinker blocks, concrete blocks, concrete hollow blocks, etc.
  • the wall 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 nets, the weakening of the material being achieved by means of cracks or grooves.
