Description

Description of the knot angle steel construction system KW - Bausystem) for the patent application dated June 25, 1968 -I.) Intentions The aim of the system is the extensive, industrial prefabrication of the supporting structures of components for the entire building construction area in steel frame construction. .

Commercially available, seamless, Galvanized hollow profiles according to DIN -1629 for use. Followed the new development the purpose of reducing construction costs through rational, serial prefabrication, to increase the quality and to shorten the overall construction time. In particular, should the weather-dependent work on the construction site is limited to a minimum will..

II.) Task and solution The production of the connections occurring in a truss system at the collision of different truss rods (nodes) should be simplified and made possible in prefabrication.

First of all, all nodes that are normally possible became one Truss set. In the detailed drawings no.

1-4, 12 nodes usually allow all of them occurring rod connections.

As a solution to the task at hand, the nodes from the -the entire framework system solved, and for itself as KNOTEN8-WINKEL to a new, and previously unknown construction element in steel frame construction.

The construction principle of the nodal angles results from the detailed drawings No. 1 - 4.

The knot angles consist of the following individual elements 1.) Vertical Connecting rod 2.) transom support -3,) column support The vertical connecting rod corresponds in its external dimensions to the internal dimensions of the vertical hollow columns, . and is inserted into the latter. With that the possibility of Manufacture of rod connections in vertical and horizontal direction given. -The transom supports are in accordance with the static requirements with the column support welded. The external dimensions of the transom supports correspond to the internal dimensions of the bars to be connected.

A bolt is connected by simply sliding it open the transom support The transom is only structurally connected to the support, because the bars are not subjected to tensile stress in the entire static system.

The column support brings about the transfer of the resulting from the transoms Support forces in the columns.

III.-) Summary and application From the connections of the to 3 basic elements belonging to the entire building system namely a) node angle b) transom c) Stems can be assembled as any truss system. As special advantages are to be emphasized 1.). a few basic elements 2.) cost-saving prefabrication of the Knot angle in a large setie 3.) No processing of the stems and bars, as these can be supplied in fixed lengths. 4.) quick and easy assembly 5.) low Weights and dimensions of the individual parts All basic elements are in a catalog comprehensible and to be offered at fixed unit prices. There is thus the possibility for a building of any kind, all construction elements in exact pieces and Record dimensions and obtain them from the warehouse.

A significant advance can be seen in the development and prefabrication of the individual node angles. This makes it possible to manufacture a load-bearing steel frame for universal use in series without typing the buildings. There is therefore no need, as is the case with the known methods, the Individual production of the individual structural members, which with their fixed connections and connecting parts are exclusively assigned a specific place in the entire structural system. The new construction element "Nodal angle °" in connection with the hollow profiles for supports and transoms allows the efficient series production of half-timbered constructions of various dimensions within the framework of the static conditions.
