Abstract
Multiple vertex joint adapter solves the problem of various free forms of n≥3 -angular, designs' mesh structures in the way that takes account of fundamental characteristics of steel structures and the ease of executing an application. The housing of the multiple vertex joint adapter is composed of n≥3 -sheet metals and of one or more reinforcing ribs. Sheet metals 1.1, 1.2, 1.3, 1.4, 5.1, 5.2, 5.3, 5.4, 9.1, 9.2, 9.3, 9.4 and 9.5 for each n≥3 on the outside polygon of the multiple vertex joint adapter feature through- or screw-boreholes. Reinforcing ribs 2.1, 2.2, 2.3, 3.1, 3.2, 3.3, 3.4, 6.1, 6.2, 6.3, 7.1, 7.2, 7.3, 7.4, 10.1, 10.2, 10.3, 11.1, 11.2, 11.3 and 11.4 are made of sheet metal with or without through-boreholes that allow screwing the flange 4.1, 4.2, 4.3, 4.4 and 8.1, 8.2, 8.3, 8.4, and 12.1, 12.2, 12.3, 12.4, 12.5 onto the vertex element and positioning a given vertex element. Reinforcing ribs are chamfered on the edges for the reasons of welding technology. In the case when multiple vertex joint adapters are cast, their detailed shape is adjusted to the casting technology. Reinforcing ribs 2 improve the strength of the multiple vertex joint adapter. Support elements of the selected shapes are screwed onto individual sheet metal pieces of the multiple vertex joint adapter with a screw connection in the way that the screw connection channels the entire load on the support element to the vertex as a static or a dynamic connection point.
Description
MULTIPLE VERTEX JOINT ADAPTER
The subject of the invention is the multiple vertex joint adapter with reinforcing ribs, onto which an n- number of the structure's support elements are attached for each n≥3, ending with a flange into which the load on the support element is channelled in the manner that there are tensile or pressure force, and shear force in each joint.
The technical problem that the invention solves is making such vertex structure that will allow a simple assembling and disassembling of profiles and the multiple vertex joint adapter, while at the same time the whole structure will fulfil n-angular vertices in a given mesh structure and will be of a simple design.
There are several existing solutions of vertex elements for connecting profiles in a mesh structure. The oldest known one is the US 4 262 461 patent. In this case, the vertex is a thin-walled cylinder onto which the structure's support elements are mounted. The drawback to this solution is the physical design of the support elements, mounted onto the vertex with special retaining rings. The solution is rather impractical as it involves a number of non-standard elements that need to be custom-made for the structure.
The other known solution follows the US 5 398 475 patent. The multiple vertex joint adapter has a conical shape, with flat spots in the places where the support elements are placed. The flat areas of the vertex also include boreholes for mounting the support element onto the vertex. The vertex is questionable from the viewpoint of manufacturing the conical element. Namely, in the case where the mesh structure is corrugated, conical vertices with different angles have to be manufactured. Later, in each vertex element we need to further offset the surfaces at the connection point between the profile and the vertex. Besides the two older solutions of making a connecting element, there are a few other patent solutions, such as US 2007/0125033, GB 2 446 908, WO 2006/123475 A1 and US 5 624 160, whose drawbacks are mainly about the physical execution of the invention or assembly. All existing vertex elements can cover only one type of the geometric mesh.
The common characteristics of the existing multiple vertex joint adapters is an attempt to make an element to connect the vertices of triangular mesh structures, with six support elements in one vertex joint. Later on, there are vertex elements, connecting three support elements, such as right-angled mesh structures. The next common characteristic of the solutions of existing multiple vertex joint adapters is placing the upper edges of support elements onto the upper edges of the connecting element, which is impossible to achieve, particularly with freeform mesh structures (e.g. n-angle mesh structure for each n≥3).
Height offsets of support elements, connected in the joint, is performed by adjusting welding joints for height. Screwing at different placings of the support element onto the vertex is solved by a different positioning of screwing bores, relative to the vertex, the support element and ribs in the vertex joint. Below, the invention will be described on an executed case and in figures, showing:

The multiple vertex joint adapter structure consists of several sheet metals 1.1 , 1.2, 1.3, 1.4, 5.1 , 5.2,
5.3, 5.4, 9.1 , 9.2, 9.3, 9.4 and 9.5 for each n>3, and mid-reinforcing ribs 2.1 , 2.2, 2.3, 3.1 , 3.2, 3.3,
3.4, 6.1 , 6.2, 6.3, 7.1 , 7.2, 7.3, 7.4, 10.1, 10.2, 10.3, 11.1, 11.2, 11.3 and 11.4, welded onto the sheet metal of vertices 1.
The assembly of flat right-angled surfaces 1.1 , 1.2, 1.3, 1.4, 5.1 , 5.2, 5.3, 5.4, 9.1 , 9.2, 9.3, 9.4 and 9.5 is welded together. The outside of the flat sheet metal assembly includes at least two or more reinforcing ribs on the inside. They are welded onto the sheet metal of each vertex joint. The vertex joint is made of steel sheet metal or any other weldable material with the strength similar to steel, as it should withstand the loads between the support elements of the structure 4.5, 4.6, 4.7 and 8.6, 8.7, 8.8, 8.9, and 12.7, 12.8, 12.9, 12.10, 12.11 , as well as outside loads that appear and act on the vertex joint adapter. The sheet metal has boreholes, allowing screw connection between the vertex joint adapter and a larger number of support elements of any given shape with an either welded or otherwise executed flange 4.1 , 4.2, 4.3, 4.4 and 8.1 , 8.2, 8.3, 8.4, and 12.1 , 12.2, 12.3, 12.4, 12.5. inside the polygon for each solution n≥3, consisting of sheet metal, at least one or several reinforcing ribs are welded. They are made from the same material as other elements or sheet metals. The ribs are chamfered so as to allow welding between the initial vertex sheet metals.
Reinforcing ribs 2.1 , 2.2, 2.3, 3.1 , 3.2, 3.3, 3.4, 6.1 , 6.2, 6.3, 7.1 , 7.2, 7.3, 7.4, 10.1 , 10.2, 10.3, 1 1.1 , 1 1.2, 1 1.3 and 1 1.4 are made with through-boreholes. The through-borehole in the rib allows
mounting the multiple vertex joint adapter onto support profiles, ending with a flange 4.1 , 4.2, 4.3, 4.4 and 8.1 , 8.2, 8.3, 8.4, and 12.1 , 12.2, 12.3, 12.4, 12.5 . with a welded support profile 4.5, 4.6, 4.7 and 8.6, 8.7, 8.8, 8.9, and 12.7, 12.8, 12.9, 12.10, 12.1 1. Besides, the borehole allows positioning in the place where the whole vertex is being assembled in accordance with the design's mesh structure. The position of reinforcing ribs depends on detailed geometry of the vertex element. Through- boreholes in vertex sheet metal should be positioned so as to allow - regardless of the reinforcing ribs on the vertex joint assembly - access for the bolt and the washer of a given size, and the access for the tool. The screw connection can be composed - the screw, the bolt and the washer - and should provide enough space for screwing. In case there is not enough space available, the screw-borehole is made into the sheet metal of the multiple vertex joint adapter in the way that allows using the screw connection in the assembly: the bolt and the washer.
Reinforcing ribs 2.1 , 2.2, 2.3, 3.1 , 3.2, 3.3, 3.4, 6.1 , 6.2, 6.3, 7.1 , 7.2, 7.3, 7.4, 10.1 , 10.2, 10.3, 1 1 .1 , 1 1 .2, 1 1.3 and 1 1.4 for the multiple vertex joint adapter are made in the way that the more stressed reinforcing rib has no through-borehole and the other rib is made with the through-borehole. The reinforcing rib without the through-borehole makes the vertex joint assembly stronger, which allows its application under high stress. Positioning of the vertex element is provided by means of an additional cylinder, welded onto the inner side of the rib without the through hole. The additionally welded cylinder has the inner diameter identical to the diameter of the borehole through the other rib. This solution prevents access to the inner part of the multiple vertex joint adapter, which requires the use of a screw-borehole, made into the connecting element. The screw-boreholes in the connecting element are used for connecting - by means of a screw connection - the multiple vertex joint adapter and the support element with flanges on both sides, either welded or otherwise attached.
The reinforcing ribs provide more strength to the whole multiple vertex joint adapter. It is required for high stress, which the structure is subject to (own weight, the elements, such as wind, snow and useful loads).
Part two covers preparing the connection between the support element and the flange 4.1 , 4.2, 4.3, 4.4 and 8.1 , 8.2, 8.3, 8.4, and 12.1 , 12.2, 12.3, 12.4, 12.5. The flange material should be identical to that of the support element 4.5, 4.6, 4.7 and 8.6, 8.7, 8.8, 8.9, and 12.7, 12.8, 12.9, 12.10, 12.1 1 in order to be able to join the support and the flange (sheet metal) with a quaiity welded joint. The number of boreholes in the flange is identical to that on the vertex sheet metal 1.1 , 1 .2, 1 .3, 1 .4, 5.1 , 5.2, 5.3, 5.4, 9.1 , 9.2, 9.3, 9.4 and 9.5. The boreholes on the flange are made in relation to the angle of the support element to the flange. The screw-boreholes on the flange should be positioned so as to allow the access of the 4.4, 8.5 and 12.6 size to the screw-borehole in the flange and the screwing itself.
Part three is dedicated to connecting support elements, ending with a flange 4.1 , 4.2, 4.3, 4.4 and 8.1 , 8.2, 8.3, 8.4, and 12.1 , 12.2, 12.3, 12.4, 12.5 and are connected with the vertex joint assembly via a screw connection. Through- or screw-boreholes on the flanges at the tips of support elements or/and on the sheet metal of the vertex assembly should be made so as to match one another and make a screw connection possible. The screw connection dimension in calculated with a view to the strength of the support element. The procedure is so designed that the support elements of the mesh structure are first specified, followed by specifying corresponding flanges that allow adequate screw connections. Only then do we begin specifying the dimensions of the multiple vertex joint adapter, defined by the strength as well as screwability and complete assembly in a space.
