Description

Profile iron connection for a strut structure using a plurality of profiled sheet metal sections, e.g. B. Post The invention is based on a profile iron connection for a strut structure using a plurality of profiled sheet metal sections, for. B. posts whose longitudinal edges are bent over by 180 'in such a way that there are two channel-like channels, as well as connecting parts for these sections , which consist of at least one clamping or wedge piece, which are received within the profile of said sheet metal sections, and with their edges are received by the said channel-like channels, the wedge pieces are thereby secured in their respective desired setting position, being clamped to the bent longitudinal edges of the said sections by means of bolts and, if necessary, one or more clamping plates, which the bent longitudinal edges of the mentioned sections overlap.

In contrast, the object of the invention is to provide compounds of the type mentioned to the extent that a stiffening that is as favorable as possible is achieved at the connection point and thus the most favorable strength ratios possible.

To solve this problem, the invention provides that the Sheet metal sections each have a profile with a right-angled cross-section and that the or each wedge also has a rectangular profile cross-section which corresponds to the inner profile of the sheet metal section in question and fills this inner profile.

In this task solution following at e7 known design features were used: It has been known for a combination of profile bar parts with movable table parts to design connectors that way. that they fill the inner profile of the profile iron parts.

Through the invention, it is achieved in a simple manner that profile iron connections of the type mentioned in the first paragraph become stiffer at the connection and thus larger Can absorb forces at the connection point. This is also supported by a Achieved construction that allows a favorable manufacturing method, as the connecting parts have very simple constructive forms.

The invention is illustrated in several exemplary embodiments with reference to the drawing; FIG . 1 shows the connecting parts in the not yet assembled state, FIG . 2 shows a cross section through the connection.

F i g. 3 diagrammatically shows the connecting parts of a second embodiment with a two-part clamping or wedge piece, FIG . 4 shows a diagram of the compound connection, FIG . 5 and 6 further exemplary embodiments of the connection when assembling more than two profile iron bodies.

From the drawing, the profile iron connection for a strut structure using a plurality of profiled sheet metal sections 1 to 9, z. B. posts whose longitudinal edges are bent by 180 'in such a way that there are two channel-like channels can be seen. There are connecting parts for these sections are provided, which consist of at least one clamping or wedge piece 10, 11 , which are received within the profile of the said sheet metal sections 1 to 9 and are received with their edges by the said channel-like channels, the wedge pieces 10, 11 are secured in their desired setting position in that they are clamped to the bent longitudinal edges of said sections with bolts 12 and, if necessary, one or more clamping plates 13 to 16 which overlap the bent longitudinal edges of said sheet metal sections 1 to 9.

The sheet metal sections 1 to 9 each have a profile with a right-angled cross-section. Each wedge 10, 11 also has a right-angled profile cross-section which corresponds to the inner profile of the relevant metal section 1 to 9 and fills this inner profile.

The wedge 11 can be constructed in two parts, so that each wedge part is inserted separately into an associated channel of the sheet metal section 3 (cf. in particular FIG. 3).

Claims (2)

Claims-1. Profile iron connection for a strut structure using a plurality of profiled sheet metal sections, e.g. B. posts, the longitudinal edges of which are bent by 180 ' so that two channel-like channels are present, as well as connecting parts for these sections, which consist of at least one clamping or partial piece, which are received within the profile of said sheet metal sections and with their edges from the said channel-like channels, the wedge pieces are thereby secured in their respective desired setting position that they are clamped to the bent longitudinal edges of said sections by means of bolts and, if necessary, one or more clamping plates which overlap the bent longitudinal edges of said sections , characterized in that the sheet metal sections (1 to 9) each have a profile with a rectangular cross-section and that the or each wedge (10, 11) also has a rectangular profile cross-section which corresponds to the inner profile of the sheet metal section (1 to 9) in question and this fills in the profile. 2. Profile iron connection according to claim 1, characterized in that the wedge piece (11) is designed in two parts, so that each wedge piece part is inserted separately into an associated channel of the sheet metal section (3).
