The present disclosure relates to a space frame, and more particularly relates to an apparatus for defining a node for the space frame.
Generally space frames are used in various industries, such as architecture, construction and any other known industries. The space frame includes multiple support structures and a node at which two or more support structures are coupled to each other. The space frame is used for carrying a load caused by a mass supported on the space frame. The multiple support structures are positioned at various angular positions to provide desired load carrying capacity to the space frame. After a prolonged period of time, the node of the space frame may incur damage due to use. Repairing the damaged node of the space frame at the field application location is a complex and time consuming process.

The bolt 203A is further engaged with the nut 203B to couple the clamping member 110 with the coupling member 108 and the support structure 102. At step 308, a tack weld is provided between the clamping member 110, the coupling member 108 and the support structure 102. Further, the first and second mounting bosses 214, 216 along with the fastening members are removed from the first and second clamping members 206, 208, respectively. In an example, a cutting tool may be used for removing the first and second mounting bosses 214, 216 from the clamping member 110. Further, the first and the second clamping members 206, 208 are welded to the coupling member 108 by depositing a welding material between the clamping member 110 and the coupling member 108. In the illustrated embodiment, the welding material is deposited within the first opening 210 to couple the clamping member 110 with the coupling member 108.
The welding material may also be deposited around a periphery of the first and second clamping members 206, 208 and the coupling member 108. In other embodiments, welding may be performed at any location between the clamping member 110 and the coupling member 108. Similarly, the first and the second clamping members 206, 208 are welded to the support structure 102 by depositing the welding material between the clamping member 110 and the support structure 102. In the illustrated embodiment, the welding material is deposited within the second opening 212 to couple the clamping member 110 with the support structure 102.
The welding material may also be deposited around a periphery of the first and second clamping members 206, 208 and the support structure 102. In other embodiments, welding may be performed at any location between the clamping member 110 and the support structure 102. Thus, each of the clamping members 110 may be welded with each of the plurality of coupling members 108 and each of the plurality of the support structures 102 of the space frame 100 via a known welding process. In various embodiments, each of the plurality of coupling members 108 and each of the plurality of the support structures 102 may be coupled by each of the clamping members 110 by known fasteners, such as bolts, rivets, and other welding methods known in the art.
The present disclosure relates to the apparatus for defining a node for the space frame 100 and a method 400 of assembling the space frame 100 having the plurality of support structures 102. The nodes for the space frame 100 may be defined by coupling the plurality of support structures 102 with the plurality of coupling members 108 of the node member 104 by the plurality of clamping members 110. According to the present disclosure, during a failure of one or more nodes of the space frame 100, the apparatus including the node member 104 and the clamping members 110 may be used for defining the one or more nodes in a short period of time. The node member 104 may be developed in a manufacturing site in accordance with a desired specification of a structure of the space frame 100.
At step 404, the method 400 includes aligning the first connecting end 202 of each of the plurality of coupling members 108 with each of the plurality of support structures 102 by the clamping member 110. The node member 104 made in the manufacturing site is taken to location of the space frame 100 structure to replace the damaged node. Each of the plurality of coupling members 108 is aligned with each of the plurality of support structures 102 by disposing each of the first and second clamping members 206, 208 on the first and the second portions 205, 209, respectively, of the outer surface 207 of the support structures 102 and the coupling members 108.
Further, the first mounting boss 214 of the first clamping member 206 and the second mounting boss 216 of the second clamping member 208 may be aligned to receive the fastening member 203. The first mounting boss 214 and the second mounting boss 216 may be further coupled with the fastening members 203. The tack weld is provided between each of the clamping members 110, the coupling members 108 and the support structures 102 of the space frame 100. Further, the first and second mounting bosses 214, 216 along with the fastening member 203 may be removed. At step 406, the method 400 includes welding each of the clamping members 110 with each of the support structures 102 and each of the coupling members 108. The welding material may be deposited through the first opening 210 and the second opening 212 of the first and second clamping members 206, 208 to couple the first and second clamping members 206, 208 with the coupling members 108 and the support structures 102, respectively.
The apparatus 200 of the present disclosure may be adapted for defining a node for various space frames. Further, the apparatus 200 may be taken to a field, where the space frame 100 is located for repairing the damaged node in short period of time. As the welding of the clamping member 110 includes a fillet weld or groove weld, an operator with less skill may be able to weld the clamping member 110 with the coupling member 108 and the support structure 102. Further, maintenance cost associated with repairing of the damaged node may be minimized as the apparatus 200 may be easily transported to the field and the welding operation may be performed with the operator having less skill in the welding operation.
While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the spirit and scope of what is disclosed. Such embodiments should be understood to fall within the scope of the present disclosure as determined based upon the claims and any equivalents thereof.
