Technology
According to Norwegian technology for the hand – cutting houses building the mount is used. The half – jig, that is a thick northern pine trunk formatting smooth surfaces of two ideally truncated obverses.
The spanner mode of a mount when constructing a wooden house, called Norwegian spanner latch, was founded in the old times by people who knew not only what the harsh climate is and what the volatile timber can be while desiccation but also how quickly all the work done by human can go down to drain. It is widely acknowledged to be on of the most stabliest and warmth – retentive from the rest in the practice range.
The following stage is the longest, the hardest and the most diligence requiring one. It is when the mound should be put into the crib. The log is put on the below lying edge of another log. Meanwhile, the another junction between two logs is footed, that is tooled with special axe. This secures the structure mould of mounts and makes the maximum junction place between logs, that gives a possibility to put a proper number of lagging material and not to lose the warmth. In the point of edge junction the complex system is drawn including trapeze – shaped lines, that compose the after so called ‘plate’s’ profile. Because the quality consequences are noticed only after few rows of cribs even the tenuous mistakes or inaccuracy aren’t allowed. After many measurements the rips are being done. Later on, the wedge form junction is manually tooled with the axe. From the overlook it seems as a saddle, that sides are diligently polished just during the process of junction production. Then, at the end of junction construction, inside the so called hidden prickle is done, that accesses the hidden junction point between logs of the bottom log. As a rule, it is done in the outer – corner junction places of a wooden house, in order to reassure the extra thermal – isolation and strength.
The unique Norwegian junction latch lies in the drying process. Therefore, this is inevitable because even when a house is being built, it still absorbs the damp, and continuously secretes it all and all again. During the drying and house crib settlement process the corner junction because of its stock weight aggregates and doesn’t let to warp to the mount from its inner intensity, differently from the standard plate. The higher drying and set are, the more impermeable junction is. Even such cases are known, when a piece of timber is taken away during the takedown of the centenarian house convolves and releases all inner stand – forces, that before were tightly connected (locked).
This kind of technology allows to use only the natural damp log, this is when the mount dries just in the crib. The special production mechanization is not being done, so the log, that itself has a natural damp, is fitted to notching only manually.
The crib of the wooden house is produced on the site of the company. This is to ensure all the possible control that is needed for all levels of the fitting. The following step is marking, and the fitting map as well is added to the main documentation kit. Then the crib is being de – fitted, taken to the fitting place and assembled just on the foundation. The pine and fir are the main timber types used for the production. The major feature, that characterizes the mount is its thickness. The most usable dimensions are 160 mm for inner and up to 240 mm for outer walls. The standard lenght of a mount is 6 m. A wall, longer than 6 m is joined, and the meeting point, as rule, is hidden in the plates. In order to avoid the longitudinal deflection and to reasure the rigidness of a construction, the walls are assembled on the wooden shelving. Moreover, the house with no spikes fundamental is highlighted.
