BACKGROUND OF THE INVENTION

The present invention relates to a rapid-construction framework, especially of steel, as a support structure for ceiling and wall plates of a building, with perpendicular supports and horizontal tie bars, all with uniform section and each with coupling elements at both ends, to produce plug connections with bottom and/or top supports, wherein each of the coupling elements comprises a main element which is hollow on the tie bar side with four shaped guide bars arranged therein, wherein at least one attached support and at least one main element, in the hollow space, engage on another tie bar, force- and form-locking and have an angular section.

In accordance with a prior construction by the inventors herein, a modular rapid-construction framework comprises perpendicular supports arranged in the grating in the form of hollow shaped bars of square section and horizontal tie bars. Tie bars and supports are connected by coupling elements welded onto both ends of the tie bar, the coupling elements being in the form of hollow main elements with shaped guide bars arranged therein, wherein at least one support and at least one main element, in the hollow space, engage on another tie bar. A special feature of this prior construction is that the shaped guide bars are open lengthwise and especially are configured as angular. Tolerance problems can thus be eliminated in a simple manner and the welding seams between the shaped guide bars and the main elements holding them can be arranged so that they do not hinder the precise fit of the framework parts.

An object of the present invention is to further improve the aforementioned prior construction, so that fewer different structural elements are needed and the assembly is further expedited in order to attain increased economy.

SUMMARY OF THE INVENTION

The present invention provides a rapid-construction framework of the aforementioned type, wherein the four shaped structural bars or beams are fitted together in an independent modular connection, while all the main elements of the rapid-construction framework on the tie bar side have a free lightweight rectangular section and are of the same dimensions for its assembly. These modular connections, as well as the tie bars, can be economically mass produced and stored. It is advantageous that different wall combinations can be economically constructed with standard or modular tie bars and the hollow structural bars or beams serving as supports and only to be cut to length, which also can be manufactured and stored, so that the axes of the couplings and the supports always fit together.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The plan of the rapid-construction framework, shown diagrammatically in FIG. 1, which can be for a building with an upper story, allows for five basic possibilities for the use of the modular connection 3 or 3' shown in FIGS. 2 and 3, respectively.

1. Supports 1, 1a and tie bars 2a, 2b of the rapid-construction framework can be fitted together in a straight line, forming a flat wall framework, as indicated in I in FIG. 1.

2. A second row of supports and therewith an additional wall framework can be attached on one wall side on each support 1, 1a, perpendicular to the first row of supports with tie bars 2d. This is indicated by II in FIG. 1.

3. Corners can be constructed (see FIG. 1, position III) with tie bars 2e and 2f and supports 1, 1a.

4. Intersecting tie bars 2g-2j can be attached to supports 1, 1a, as indicated by IV in FIG. 1, to support two adjacent walls, which can be perpendicular to a main wall.

5. Finally, a greater distance can be bridged over with a tie bar 2k of two or three times the modular length between each two supports 1, 1a, so that one or two supports can be dispensed with and a larger passageway can be maintained between two inside rooms of the building.

For all of the variations shown in FIG. 1, it is essential that these can be provided entirely with standard (modular) tie bars 2a-2k and also with support 1, 1a of hollow structural bars or beams, using modular connections 3 and/or 3'.

Modular connection 3 in FIG. 2 comprises a hollow structural bar segment 4 of low structural height, into which are symmetrically welded four shaped guide bars 5 of angular section. Hollow shaped segment 4 has the section dimensions of hollow supports 1, 1a. Shaped guide bars 5 are of the same length, but their length is many times longer than the structural height of hollow segment 4. Shaped guide bars 5 preferably are welded only on their lengthwise edges with the inside of hollow segment 4, The modular connection can also be manufactured as one integral unit (e.g. light die cast metal or cast iron), as indicated by 3' of FIG. 3.

Furthermore, it is important for the function of modular connection 3, 3' to have the space "a" between the four angular segments, as shown in FIG. 2. This space "a" may be only slightly greater than double the wall thickness "s" of hollow main elements 4a, 4b and so forth, which are welded onto the ends of the bars 2a, 2b and so forth, because this type of design assures a force-locking connection by simple fitting together of the structural elements. Therefore it is also important that the "structural play" be such that during the assembly of the parts which are to be assembled, only relatively slight friction is to be overcome. The edge dimensions "A" of modular connection 3, therefore, may be only slightly smaller than the small width "J" of supports 1, 1a as well as hollow main elements 4a, 4b and so forth, welded at the ends of tie bars 2a2b and so forth.

Hollow main elements 4a-4j are either of the same section as supports 1, 1a or, as is shown in the exemplary embodiments, are of half the size of the support section. The structural height of these main elements is lower than the structural height of the tie bars themselves. Furthermore, these main elements are welded offset downwardly or upwardly at the ends of the tie bars relative to the tie bar axes. It is also important that these elements 4a-4j can all be at the same level, so that tie bars 2a-2k can be mass produced as modules.

FIGS. 4-7 show main elements 4a-4j each coupled at the end of the corresponding tie bar with the top or bottom ends of supports 1, 1a, so that modular connections 3 with their four shaped guide bars 5 are inserted through hollow main elements 4a-4j engaging in the hollow space of supports 1, 1a. In this manner, with a modular connection 3 or 3', it is possible to attach two, three or four tie bars simultaneously to a bottom support 1 and a top support 1a.

Since the hollow main elements 4a-4j at the ends of tie bars 2a-2i generally have only half the section of supports 1, 1a, but have lower structural height than the entire coupling, e.g. in the cases of FIGS. 4, 5 and 6, additional leveling members 40 or 41 must be used. Leveling member 40 (FIG. 4) has the complete secion of supports 1, 1a, but leveling member 41 has only half the section of supports 1, 1a. On the other hand, both types of leveling members 40, 41, have the same structural height as main elements 4a-4j at the tie bar ends. Leveling members 40, 41 are therefore integrated as needed to assure force transmission between tie bars and supports in the couplings.

An assortment of modular parts is thus produced, which allows the necessary wall or room combinations in a rapid-construction framework, e.g., for a residence. Windows or doors or other passageways also can thus be provided between any two supports 1 or 1a.

FIG. 4 shows the area I of FIG. 1 in detail, wherein, to produce a straight wall, supports 1, 1a lie in a row and tie bars 2a, 2b are attached to supports 1, 1a by a modular connection 3 and a leveling member 40.

FIG. 5 shows the arrangement of area II of FIG. 1. In this case, a row of supports meets another row of supports perpendicular to it and therefore is attached to supports 1, 1a by means of modular connection 3 and also to the two tie bars 2b and 2c, both perpendicularly aligned with tie bar 2d, wherein a leveling member 41 which is identical with hollow main element 4d is required opposite element 4d.

FIG. 6 shows the coupling in the area III of FIG. 1, wherein tie bars 2e and 2f are connected force- and form-locking by modular connection 3 at a right angle to supports 1, 1a. Two leveling members 41 are required with this arrangement, which are identical with main elements 4e and/or 4f at the ends of tie bars 2e and 2f.

FIG. 7 shows the area IV of FIG. 1. Modular connection 3 here provides the form- and force-locking connection of tie bars 2g, 2h, 2i, 2j intersecting with supports 1, 1a.

FIG. 8 shows a diagonal 20e which can be arranged between two adjacent supports 1, which however requires the use of modular connections 3, of which shaped guide bars 5 instead of hollow segment 4 extend downwardly for the length of hollow main element 4e. Leveling member 41 which is then required must likewise have double structural height.
