Profile arrangement with connecting elemet for sectional girders

a technology of connecting elemets and sectional girders, which is applied in the direction of rod connections, structural elements, building components, etc., can solve the problems of inability to create connection load too large, low load-carrying capacity of butt joints of known profile arrangements, etc., and achieve the effect of substantial load-carrying capacity

Benefits of technology

[0007]It is an object of the present invention to provide a profile arrangement which will overcome the aforementioned disadvantages and which will be flexible in design.

Problems solved by technology

The disadvantage of the known approach is that the butt joints of the known profile arrangement have a lower load-carrying capacity than the sectional girders themselves.
Therefore, for static reasons, it is not possible to select any given butt joint of the sectional girders, particularly in the case of a profile arrangement in the form of a multiple-span girder that rests on a plurality of supports, since, otherwise, the load on the connection that is created is too great.

Embodiment Construction

[0023]FIG. 1 shows a load-bearing structure 6 for solar panels which have four profile arrangements 11 supported on supports 7. In this example, each profile arrangement 11 has two coaxially serially disposed sectional girders 12, which are joined at butt joints 13 thereof by a connecting element 16. Each connecting element 16 is introduced into the corresponding end region of sectional girders 12 to join the same. Sectional girders 12 are hollow profile sections which are formed as extruded sections of aluminum, for example.

[0024]Each connecting element 16 (see FIG. 3) has a value of its section modulus Wy1 that differs maximally by 10%, advantageously maximally by 5%, from the value of the corresponding section modulus Wy2 of sectional girders 12. Connecting element 16 is a peripherally closed, hollow profile section that is fabricated as an extruded section of aluminum, for example. Connecting element 16 has an asymmetrical cross section, which is designed for introduction into t...

Abstract

A profile arrangement (11) has two coaxially serially disposed sectional girders (12) and having a connecting element (16), the connecting element (16) having a value of its section modulus (Wy1) that differs maximally by 10% from the value of the corresponding section modulus (Wy2) of the sectional girders (12).

Description

[0001]This claims the benefit of German Patent Application DE 10 2009 026 512.0, filed May 27, 2009 and hereby incorporated by reference herein.[0002]The present invention relates to a profile arrangement.BACKGROUND[0003]These types of profile arrangements are used, for example, as parts of a load-bearing structure that rests on a plurality of supports. In particular, in the case of solar park installations, frame structures having such profile arrangements are erected, upon which solar modules are mounted.[0004]Since the sectional girders, i.e. profile supports, are mostly available in standard lengths, it is necessary to interconnect a plurality of coaxially serially disposed sectional girders at the butt joints thereof by a connecting element in order to construct longer sections.[0005]A profile arrangement having two coaxially serially disposed sectional girders and having a connecting element that is introduced into the end regions of the sectional girders to join the same is k...
