Abstract
An I-beam with a main beam body and a head at each end. The heads are symmetrical widthwise laterally of the beam body with each head having an outwardly facing side shaped to define two identical, longitudinally outwardly facing grooves. Each groove is shaped by longitudinally outwardly facing ribs and by transverse ribs at the free ends of the first mentioned ribs to define an opening into an undercut region inside the groove. The heights of the ribs are selected relative to the width of the grooves so that the height of the laterally outer rib of one beam fits into the height of the undercut of the groove of the other beam when the rib of one beam is installed in the groove of the other. The ribs in the grooves are shaped to support the rib of the head of one beam in the groove of the other when the beam bodies are at right angles. In an alternative design, there may be a third groove between the two outer grooves.
Description
I-BEAM FOR BUILDING STRUCTURES
BACKGROUND OF THE INVENTION
The present invention relates to an I-beam according to the preamble of claim 1 and to its use for building structures.
I-beams for building structures are known, for example, from DE-A-196 36 802.
The term I-beam is intended to mean profile bars, in particular made of metal, for example iron or preferably aluminum, which have two opposite heads and one or more head-connecting webs, wherein the heads project symmetrically beyond the at least one web on both sides. Such profile bars are also known as double-T
profiles.
SUMMARY OF THE INVENTION
The invention is intended to achieve the object of developing I-beams of the above type such that they can be connected to one another without any additional tools or any additional fastening means. The design is intended to be straightforward enough for even unskilled workers to be able to use it to erect structural skeletons and entire buildings in a short period of time.
This object is achieved according to the invention by an I-beam with a main beam body and a head at one or preferably at each end. The heads are symmetrical widthwise laterally of the beam body with each head having an outwardly facing side shaped to define two identical, longitudinally outwardly facing grooves. Each groove is shaped by longitudinally SPEC\298954 outwardly facing ribs and by transverse ribs at the free ends of the first mentioned ribs to define an opening into an undercut region inside the groove. The heights of the ribs are selected relative to the width of the grooves so that the height of the laterally outer rib of one beam fits into the height of the undercut of the groove of the other beam when~the rib of one beam is installed in the groove of the other. The ribs in the grooves are shaped to support the rib of the head of one beam in the groove of the other when the beam bodies are at right angles. In an alternative design, there may be a third groove between the two outer grooves.
According to the invention, the longitudinal grooves are formed such that a second, identical profile with a longitudinal rib can engage in a longitudinal groove of the double-T profile and the second profile can be turned in the groove such that the two profiles form a corner of a building without additional profiles or screws being necessary.
The corner structure of the building forms a cavity in which service installations or rainwater outlets can be installed.
The heads are also referred to as flanges.
Their height is at least 6 millimeters. Panels can be plugged laterally or longitudinally onto the head ends or flange ends, wherein the panels either have an end-side groove or have a gripper fastened on them which, together with the panel, forms such an end-side groove. It is possible for the panels to butt so closely against the I-beams that, even in storm conditions, it is not possible for any water to penetrate between the beam and the panels into an interior. Rainwater and condensed water can run off in the longitudinal grooves.
SPEC\298954 On two mutually opposite end sides, the panels preferably each have a groove by which they can be plugged laterally onto a head part of a beam. The groove arranged on one side is considerably deeper than the groove arranged on the other side. As a result, by virtue of displacement of the panel sideways in relation to the head of the beam, the panel can be disengaged from the head on one side and can then be pivoted out laterally and then, by virtue of lateral displacement in the opposite direction, the panel can also be disengaged from the head of the other beam in each case.
As a standard profile, it is proposed that the I-beams, measured over the outer surfaces of their two heads, have a height of 100 millimeters.
Other features and advantages of the present invention will become apparent from the following description of the invention which refers to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows two heads of two I-beams, with both beams shown in a broken-away state, according to the invention and the beams in an oblique position relative to one another during insertion of a lateral head end of one beam into an undercut in a longitudinal groove on the outside of the head of the other beam, and Figure 2 shows part of a building according to the invention which is formed using I-beams and plug-connected panels.
DETAILED DESCRIPTION OF THE INVENTION
The two double-T beams or I-beams 10, shown in a broken-away state in Figure 1, are for building SPEC\298954 structures. They are formed in a symmetrically identical manner heightwise and widthwise. Each of the top sides of their two flanges or heads 12 have two identical longitudinal grooves 14 which are undercut symmetrically at 16 on both lateral sides of each groove and all of the grooves are of the same cross-sectional shape and cross-sectional size. The undercuts 16 on both lateral sides of the grooves 14 have a rectangular cross-sectional shape with rounded corners. The narrowest width open region of each longitudinal groove 14 is formed by respective transverse ribs 18 which are directed toward one another, are located at and define the top surface of the groove or its entrance and the ribs are the end sections of longitudinal ribs 20 which bound the longitudinal grooves 14 laterally. A longitudinal rib 22 is arranged between two adjacent longitudinal grooves 14 and also has two such transverse ribs 18, which project away from one another defining the entrance ends of the respective grooves. Beneath the transverse ribs 18, the longitudinal grooves 14 have a rectangular cross-sectional shape. The groove base 24 is flat.
The two opposite heads 12 of each beam 10 are connected to one another by a web 26 and the heads extend symmetrically both longitudinally and laterally on both sides beyond the web 26. The web 26 and the two associated heads 12 are together comprised of a single piece of material, preferably aluminum. However, other materials, for example iron or plastic, possibly may be used.
The width B1 comprised of the width of the outer longitudinal ribs 20 and the length of the respective transverse rib 18 is equal to, or only slightly smaller than, the height H1 of the lateral SPEC~298954 undercuts and also has the same form as these undercuts.
The entire height H2 of the heads 12 is dimensioned, over the outer longitudinal rib 20 of said heads, such that one lateral head end of another identically shaped I-beam 10 can be inserted transversely, by insertion of an outer longitudinal rib 20, into any one of the longitudinal grooves and can be introduced into the undercut 16 of the relevant longitudinal groove 14 in Figure 1 such that the webs 26 of the two beams 10 are at right angles to one another. The width B1 of the outer longitudinal rib 20 and the relevant undercut 16 form a mutually retaining type of fit. The web 26 is arranged symmetrically in the center with respect to the longitudinal grooves 14.
Type of fit or fit is intended to mean all interengageable shapes and dimensions by way of which the two interengaged parts are mutually retained in at least two directions of movement. The term fits can be gathered, for example, from DIN 7154, 7155 and 7157 and from "Dubbel Taschenbuch fur den Maschinenbau", [Dubbel pocketbook for mechanical engineering], 15th edition, pages 339 and 340.
In a preferred embodiment, the height H2 of the heads 12, measured over the outer longitudinal ribs 20 of the latter, is greater than the groove width B2 at the narrowest point thereof between the ends of the ribs 18.
Consequently, in the event of slippage in the transverse direction, i.e. left or right in Fig. l, the outer longitudinal rib 20 fitted into an undercut 16 cannot be moved out of the longitudinal groove 14, or drop out of the same groove. Instead, for the purposes of separation and assembling two beams 10, the latter have to be initially positioned obliquely corresponding to Figure 1.
SPEC~298954 The lateral outer edges 30 of the heads 12 are preferably set back, for example of flattened or round design, in order that the head 12 of one beam 10 can be inserted more easily into a longitudinal groove 14, and S the undercut 16 thereof, of another beam 10, as can be seen from Figure 1.
Measurements are given in millimeters in Figure 1. These measurements are only examples for a possible embodiment, and the invention is not restricted thereto.
Figure 2 shows, in a broken-away state, a building structure with a plurality of beams 100 which are designed incorporating the concept of the two beams of Figure 1, with the exception that a central longitudinal groove 32 is additionally formed between the two outer longitudinal grooves 14. The central groove 32 is located laterally symmetrically over the web 26 and may be designed to be identical to, or different from, the lateral longitudinal grooves 14. For this reason, the parts in Figure 2 are provided with the same designations which correspond to the,parts of Figure 1.
The two central longitudinal ribs 22, which bound the central longitudinal groove 32, form additional protection against the penetration of storm water at the joints 34 of building panels 36 (wall, ceiling, floor or roof panels). On their mutually remote end sides, the building panels 36 have fitting grooves 38 and 40 into which the heads 12 of the beams 100 of Figure 2 (or of the beams 10 of Figure 1) can be plugged. The building panels 36 can be plugged on laterally, rather than having to be plugged onto the heads 12 in the longitudinal direction of the beams 100. Nevertheless, in the assembled state, the building panels 36 cannot slip out of the beams 100. Only the fitting groove 38 at one SPEC~298954 panel end is deeper than the fitting groove 40 at the other panel end to such an extent that the building panel 36 can be pushed sideways onto the beam head 12 at one panel end (but not in the direction of the other panel end) to such an extent that a fitting rib 42 of the fitting groove 40 can be moved out transversely at the beam head 12 of the other panel end. As a result, it is also possible for the one fitting groove 38 to be drawn off from the beam head 12 at the one panel end.
The building panels 36 may be rectangular or narrow enough to be referred to as sheets.
All the longitudinal grooves 14 and 32 of the beams 10 and 100 can collect and discharge rainwater and condensed water. As shown in Figure 2, the beams 10 and 100 can be used to form building corners 44 in which there is located a cavity 46 which can be used for the installation of rainwater discharge lines, domestic-water lines, electric cables, ventilation lines, etc.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.

This object is achieved according to the invention by an I-beam with a main beam body and a head at one or preferably at each end. The heads are symmetrical widthwise laterally of the beam body with each head having an outwardly facing side shaped to define two identical, longitudinally outwardly facing grooves. Each groove is shaped by longitudinally SPEC\298954 outwardly facing ribs and by transverse ribs at the free ends of the first mentioned ribs to define an opening into an undercut region inside the groove. The heights of the ribs are selected relative to the width of the grooves so that the height of the laterally outer rib of one beam fits into the height of the undercut of the groove of the other beam when~the rib of one beam is installed in the groove of the other. The ribs in the grooves are shaped to support the rib of the head of one beam in the groove of the other when the beam bodies are at right angles. In an alternative design, there may be a third groove between the two outer grooves.
According to the invention, the longitudinal grooves are formed such that a second, identical profile with a longitudinal rib can engage in a longitudinal groove of the double-T profile and the second profile can be turned in the groove such that the two profiles form a corner of a building without additional profiles or screws being necessary.

As a standard profile, it is proposed that the I-beams, measured over the outer surfaces of their two heads, have a height of 100 millimeters.
Other features and advantages of the present invention will become apparent from the following description of the invention which refers to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows two heads of two I-beams, with both beams shown in a broken-away state, according to the invention and the beams in an oblique position relative to one another during insertion of a lateral head end of one beam into an undercut in a longitudinal groove on the outside of the head of the other beam, and Figure 2 shows part of a building according to the invention which is formed using I-beams and plug-connected panels.
DETAILED DESCRIPTION OF THE INVENTION
The two double-T beams or I-beams 10, shown in a broken-away state in Figure 1, are for building SPEC\298954 structures. They are formed in a symmetrically identical manner heightwise and widthwise. Each of the top sides of their two flanges or heads 12 have two identical longitudinal grooves 14 which are undercut symmetrically at 16 on both lateral sides of each groove and all of the grooves are of the same cross-sectional shape and cross-sectional size. The undercuts 16 on both lateral sides of the grooves 14 have a rectangular cross-sectional shape with rounded corners. The narrowest width open region of each longitudinal groove 14 is formed by respective transverse ribs 18 which are directed toward one another, are located at and define the top surface of the groove or its entrance and the ribs are the end sections of longitudinal ribs 20 which bound the longitudinal grooves 14 laterally. A longitudinal rib 22 is arranged between two adjacent longitudinal grooves 14 and also has two such transverse ribs 18, which project away from one another defining the entrance ends of the respective grooves. Beneath the transverse ribs 18, the longitudinal grooves 14 have a rectangular cross-sectional shape. The groove base 24 is flat.
The two opposite heads 12 of each beam 10 are connected to one another by a web 26 and the heads extend symmetrically both longitudinally and laterally on both sides beyond the web 26. The web 26 and the two associated heads 12 are together comprised of a single piece of material, preferably aluminum. However, other materials, for example iron or plastic, possibly may be used.
The width B1 comprised of the width of the outer longitudinal ribs 20 and the length of the respective transverse rib 18 is equal to, or only slightly smaller than, the height H1 of the lateral SPEC~298954 undercuts and also has the same form as these undercuts.
The entire height H2 of the heads 12 is dimensioned, over the outer longitudinal rib 20 of said heads, such that one lateral head end of another identically shaped I-beam 10 can be inserted transversely, by insertion of an outer longitudinal rib 20, into any one of the longitudinal grooves and can be introduced into the undercut 16 of the relevant longitudinal groove 14 in Figure 1 such that the webs 26 of the two beams 10 are at right angles to one another. The width B1 of the outer longitudinal rib 20 and the relevant undercut 16 form a mutually retaining type of fit. The web 26 is arranged symmetrically in the center with respect to the longitudinal grooves 14.
Type of fit or fit is intended to mean all interengageable shapes and dimensions by way of which the two interengaged parts are mutually retained in at least two directions of movement. The term fits can be gathered, for example, from DIN 7154, 7155 and 7157 and from "Dubbel Taschenbuch fur den Maschinenbau", [Dubbel pocketbook for mechanical engineering], 15th edition, pages 339 and 340.
In a preferred embodiment, the height H2 of the heads 12, measured over the outer longitudinal ribs 20 of the latter, is greater than the groove width B2 at the narrowest point thereof between the ends of the ribs 18.
Consequently, in the event of slippage in the transverse direction, i.e. left or right in Fig. l, the outer longitudinal rib 20 fitted into an undercut 16 cannot be moved out of the longitudinal groove 14, or drop out of the same groove. Instead, for the purposes of separation and assembling two beams 10, the latter have to be initially positioned obliquely corresponding to Figure 1.
SPEC~298954 The lateral outer edges 30 of the heads 12 are preferably set back, for example of flattened or round design, in order that the head 12 of one beam 10 can be inserted more easily into a longitudinal groove 14, and S the undercut 16 thereof, of another beam 10, as can be seen from Figure 1.
Measurements are given in millimeters in Figure 1. These measurements are only examples for a possible embodiment, and the invention is not restricted thereto.
Figure 2 shows, in a broken-away state, a building structure with a plurality of beams 100 which are designed incorporating the concept of the two beams of Figure 1, with the exception that a central longitudinal groove 32 is additionally formed between the two outer longitudinal grooves 14. The central groove 32 is located laterally symmetrically over the web 26 and may be designed to be identical to, or different from, the lateral longitudinal grooves 14. For this reason, the parts in Figure 2 are provided with the same designations which correspond to the,parts of Figure 1.
The two central longitudinal ribs 22, which bound the central longitudinal groove 32, form additional protection against the penetration of storm water at the joints 34 of building panels 36 (wall, ceiling, floor or roof panels). On their mutually remote end sides, the building panels 36 have fitting grooves 38 and 40 into which the heads 12 of the beams 100 of Figure 2 (or of the beams 10 of Figure 1) can be plugged. The building panels 36 can be plugged on laterally, rather than having to be plugged onto the heads 12 in the longitudinal direction of the beams 100. Nevertheless, in the assembled state, the building panels 36 cannot slip out of the beams 100. Only the fitting groove 38 at one SPEC~298954 panel end is deeper than the fitting groove 40 at the other panel end to such an extent that the building panel 36 can be pushed sideways onto the beam head 12 at one panel end (but not in the direction of the other panel end) to such an extent that a fitting rib 42 of the fitting groove 40 can be moved out transversely at the beam head 12 of the other panel end. As a result, it is also possible for the one fitting groove 38 to be drawn off from the beam head 12 at the one panel end.
The building panels 36 may be rectangular or narrow enough to be referred to as sheets.
All the longitudinal grooves 14 and 32 of the beams 10 and 100 can collect and discharge rainwater and condensed water. As shown in Figure 2, the beams 10 and 100 can be used to form building corners 44 in which there is located a cavity 46 which can be used for the installation of rainwater discharge lines, domestic-water lines, electric cables, ventilation lines, etc.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.

The combination of claim 8, wherein one of the fitting grooves of the one panel at one lateral side of the head of a beam is deeper along the length of the panel, which is also the lateral width of the beam, than is the depth of the fitting groove of the other panel at the other lateral side of the head of the beam, with the depth of the fitting groove in the one panel being greater to such an extent that upon lateral displacement of the building panel in the direction of the deeper fitting groove, the shallow fitting groove of the panel can be disengaged from the head of the beam.
10. A building beam having a beam body with ends and having at least one head at at least one end of the beam body, the head of the beam being symmetrical widthwise of the beam body;
the head having a top, longitudinally outwardly facing side, which is shaped to define at least two identical, longitudinally outwardly facing grooves, each groove having a width laterally of the beam;
the head being shaped so that each groove is shaped to be undercut symmetrically on both lateral sides of the groove, each groove being laterally bounded by a respective laterally inward, longitudinally outwardly extending rib and a respective laterally outward, longitudinally outwardly extending rib, the heights of the ribs being related to the width of the grooves such that the height of the laterally outer rib fits into the height of the undercut of the groove when the laterally outer rib of a first one of the beams is installed in one of the grooves of a second one of the beams with the first and second beams being oriented at right angles to one another and where the heads of the first and second beams are identical such that when the main bodies of the two beams are at right angles to one another, the height of the laterally outer rib of the second beam is selected to form a mutually retaining fit with the undercut of the groove of the first beam.
the head having a top, longitudinally outwardly facing side, which is shaped to define at least two identical, longitudinally outwardly facing grooves, each groove having a width laterally of the beam;
the head being shaped so that each groove is shaped to be undercut symmetrically on both lateral sides of the groove, each groove being laterally bounded by a respective laterally inward, longitudinally outwardly extending rib and a respective laterally outward, longitudinally outwardly extending rib, the heights of the ribs being related to the width of the grooves such that the height of the laterally outer rib fits into the height of the undercut of the groove when the laterally outer rib of a first one of the beams is installed in one of the grooves of a second one of the beams with the first and second beams being oriented at right angles to one another and where the heads of the first and second beams are identical such that when the main bodies of the two beams are at right angles to one another, the height of the laterally outer rib of the second beam is selected to form a mutually retaining fit with the undercut of the groove of the first beam.
11. A beam for construction having a beam body, opposite sides and a head at at least one of the opposite sides of the beam, the head having a top outwardly facing side in which at least two grooves are formed symmetrically laterally of the beam body with each of the grooves being formed between a laterally inner and a laterally outer longitudinally projecting rib defined in the head;
each of the ribs having a longitudinally outer end on which a short length transverse rib is defined with the transverse ribs on the laterally inner and outer ribs projecting toward each other to define a narrow entrance region into the respective groove between the ends of the transverse ribs and also defining an undercut in each of the grooves, such that a laterally outer rib of an identically shaped head of another of the beams can be entered through the entrance region between the transverse ribs of the head of the first mentioned beam with the laterally outer rib of the other beam being 20 obliquely inclined, and the height of the laterally outer rib of the other beam being adapted to retaining fit with the groove of the one beam.
each of the ribs having a longitudinally outer end on which a short length transverse rib is defined with the transverse ribs on the laterally inner and outer ribs projecting toward each other to define a narrow entrance region into the respective groove between the ends of the transverse ribs and also defining an undercut in each of the grooves, such that a laterally outer rib of an identically shaped head of another of the beams can be entered through the entrance region between the transverse ribs of the head of the first mentioned beam with the laterally outer rib of the other beam being 20 obliquely inclined, and the height of the laterally outer rib of the other beam being adapted to retaining fit with the groove of the one beam.
