Description

TITLE
Shuttering joist for bricklaying work over window and door openings
TECHNICAL FIELD
The present invention refers to a lintel for masonry above windows and doorways, comprising a L-shaped sheet-metal angle profile, with a substantially horizontal base shank part which is provided with a declining flange on the edge which is opposite from the that side which supports a back shank part, which back shank part is directed upwards from said base shank part and is connected to supplementary sheet metal parts to form a closed section together with the rear side of the back shank part, and which profile forms a lintel that serves as a remaining lead off for rain-water from the rear side of the wall to its front side, after completion of the wall.
BACKGROUND OF THE INVENTION
Lintels according to the above are commercially available in sheet metal, which are being used in combination with a stainless reinforcement ladder. The reinforcement involves a substantial rise in the price since it negatively influences all links such as manufacturing, storage, freight and masonry.
Different variants of lintels that at least partly form a closed profile are known, for an example through US 4020612, GB 706218 and DE 2533856. The purpose with the box shape is to increase the bending stiffness, so that further reinforcement is not needed. However, known lintels displays drawbacks in the form of high weight in relationship to stiffness. Besides, each end of the beam may need to be in engagement with the butt joint between two bricks, which can be difficult to achieve, since bricks can vary in length up to one centimetres.
THE TECHNICAL PROBLEM The purpose of the present invention is to achieve a lintel which more effectively utilizes the material, so that necessary rigidity is achieved with low weight.
THE SOLUTION This is achieved according to the invention, by means of that in position of use, the closed profile section extends for some distance below the underside of the lower edge of the base shank part and includes a sheet metal part which is parallel to the underside of the base shank part and forms a support surface along the inside of the wall, in level with the lower edge of the flange.

DESCRIPTION OF EMBODIMENTS The lintel 10 shown in Fig. 1-6 is preferably made by rollforming of sheet metal, and includes as a base element a L-shaped angle profile, with a primarily horizontal base shank part 11 and a back shank part 12 rising upward from said part. The upper side of the base shank part 11 forms a support surface for bricks at masonry, for example above a door or window opening, or a form of base for masonry. When the brick wall is finished, the lintel may be left remaining and then acts as a lead out for rain water, so that the water which can penetrate through a brick wall and run along the back side of said wall, can be led out along the back shank part between the upper side of the base shank part and the underside of the brickwork.
The base shank part 11 is connected to the back shank part 12 via an obliquely upwards inclined connection part 13, which ensures that a certain distance between the rear of the brickwork and the back shank part 12 is maintained, so it can lead out the water on the top side of the base shank part.
The base shank part 11 is provided with a downwards pointing, V-shaped flange 14 on the side which is turned away from the back shank part 12. The back shank part 12 is extended towards complementary sheet metal parts, of which a first sheet metal part 15 extends obliquely upwards from the top edge 16 of the rear of the back shank part and which contributes to collect water that runs down along the inside of the masonry.
A second sheet metal part 17 extends vertically downwards from the top edge 18 of the first part 15, past the underside of the base shank part and passes via a fold edge 19 over to a third sheet metal part 20. This part 20 runs in parallel with the underside of the base shank part, at a certain distance below its underside, and forms a support surface on the same level as the lower edge of the flange 14. The sheet metal part 20 is concluded by an upwards pointing part 21 that reaches up to the underside of the base shank part and is connected to this underside, e.g. by spot welding, riveting or by a so called "TOG-L-LOC"-joint.
Consequently, the back shank part 12 forms a closed box beam in cooperation with the parts 15, 17 and 19. This beam is intended to bear together with the flange 14 at both ends of the beam upon the upper side of the brick 24 (see Fig. 6), at each side of the wall opening.
The base shank part 11 is, in the area of said support parts at the ends of the beam, provided with countersinks 22 to the level of the sheet metal part 20 and the lower edge of the flange 14. These countersinks 22 are provided with upwards pressed deformations by means of a line of gill- formed openings 23. The openings 23 are oriented away from the respective beam end and is intended to be filled by mortar, when lintel is pressed downwards into the mortar which is laid out in advance on the surfaces which shall form a bearing for the beam. By means of this anchoring of the box beam in the horizontal joint at both the bearings, the box beam is made to function as a reinforcement in the masonry beam.
When using long lintels, e.g. at buildings with large continuous window parts, consoles are used which are attached to the inner wall which carries the facing. The consoles are mounted at suitable mutual distance and forms a bearing for the lintels.
Fig. 7 discloses a first embodiment of a console during use at bricklaying of a cavity wall 24 outside an existing wall 25, which is provided with additional insulation and a plastered base 25a. The console 26 is L-formed with flat iron part 28 which is attached to the existing wall with bolts 27 and a T-beam part 29 projecting in right-angle from said part 28. The beam part 29 is provided with a welded block 30 which positions the lintel 10 in abutment against the inside of the flange 14 and against the oblique part 21. The consoles 26 are mounted before the base 25a is plastered and can also be used for suspension of steel fabric in the plaster layer. The consoles and the lintel together form a support for a facing brick wall which lacks base support, for example when adding insulation to existing buildings.
If it is necessary to join together several lintel sections to a continuous length, it is possible to use joint pieces 31, 32. The joint piece 31 is pushed into the closed rear profile section of the lintel 10 and the joint piece 32 is pushed into the V-formed flange part 14.
Fig. 8 and 9 shows an alternative console 33 which is designed similarly as the console 26 with a flat iron part 28 and a projecting T-beam part 29. The console 33 is however equipped with downwards and to the sides projecting angle stay 34, and it is intended to be used differently. Consequently, the consoles 33 are to be mounted at suitable mutual distance, corresponding to the length of the lintel sections. Thus, the angle stays 34 carry the lintel ends and masonry takes place in such a manner that the downward pointing flange of the T-beam part 29 will be located in the butt joint between two brick stones. The top side of the T-beam part can form a support for a reinforcement ladder 35 which is inserted into the horizontal joint of the brick wall. After grouting of the wall, the ends of the consoles will be completely concealed.
Both they above described console embodiments can be used in combination with the lintel for formation of a reinforced wall beam during bricklaying around inside and outside corners. Hereby, the lintel ends are cut in mitre, e.g. in 45° angle, and are mounted together by means of joint pieces which are bent in angle.
The invention is not limited to the above described embodiments, but more variants are conceivable within the scoop of the following claims. For example, the countersunk part 22 can be designed differently.
