Manufacturing process

Manufacturing Process:

The Space Frame manufacturing process at LANIK is as follows. A large part of the constituents are acquired from specialized manufacturers in the neighbourhood, since LANIK is located in one of the major metalworking centers in Spain. So, materials normally purchased by LANIK include tubes, cones, bolts, caps and spherical joints.

The manufacturing process peculiar to LANIK consists in the following basic operations:

a) Manufacturing of bars.-

Characteristics of the materials

Spheres:
Carbon steel F-1140 in accordance with UNE-36011 (similar to AISI 1040 or 1045 and to steel CK-40 in accordance with DIN norms.

Tube:
Normally, tubes made in threes with longitudinal welding are used.  They are easy to weld tubes which fulfil the specifications described in the Spanish regulation MV-108-1976.

Space frames

"Seo" System

General description

The SEO space grid constructional system is based on bars and joints that are united together by means of cones and bolts.

The joint consists of a one-piece forged node having a given number of threaded holes according to geometry and to the node position in space, the number of holes being restricted only by the minimum angle determined by adjacent bars interference.

Structures tridimensionnelles

Système "Seo"

Description générale structures tridimensionnelles:

Le système d'assemblage comprend une sphère forgée monopièce, pourvue d'un certain nombre de trous filetés en fonction de la géométrie et de l'emplacement de la sphère dans l'espace, le nombre de trous n'étant limité que par l'angle minimum défini par l'interférence entre deux barres contigües.

Contrôles

Système "Ortz"

Contrôles

Dans la fabrication des composants des Structures tridimensionnelles, réalisées par système ORTZ deux types de contrôle sont appliqués:

- Contrôle de réception des matériaux.
- Contrôle de fabrication intérieure.
   
Ceux du premier groupe pourraient se subdiviser-en:

a) Contrôles dimensionnels et d'aspect qui s'effectuent dans nos ateliers, ainsi que certains contrôles métallurgiques, duretés, etc.

Checks

In the manufacture of the components of the Spatial Structures made with the ORTZ system, two types of tests are carried out:

- Reception of materials
- Interior construction

Those in the first group can be subdivided as follows:

a) Dimensional checks carried out in our workshops, as well as some others such as metallurgical and strength etc.
