97906 Thermally insulated hire element

The invention relates to a hire element according to the preamble of claim 1. Due to the increasing popularity of log construction, several different element and solid log solutions have been developed. Because the k-value of the log is poor compared to thermal insulation, the log building must be thermally insulated, or made of the thickest possible log.

10

If the log is further insulated from the inside using log panel, mineral wool and plastic, the most important feature of the log, breathability, will be lost. In addition, the sagging of the log must be taken into account when installing the collars.

15

When making a wall from a thick solid log, the problem becomes deformations and cracks caused by the drying of the log. Attempts are made to eliminate this by making a log from two or more boards like glulam. A lot of wood is wasted 20 because the boards have to be planed before gluing and the finished log also after gluing. In addition, gluing requires large hot production facilities and expensive press equipment, i.e. large investments. 1 2 3 4 5 6 7 8 9 10 11

One option is to make the building from two separate 2 sweat circles, between which mineral wool is installed or 3 are blown with pulp blasting pulp. In doing so, the wall becomes unnecessarily thick and the wood consumption is 5 high.

6 7

It is also known in advance to manufacture a log by connecting the log boards on the outer surfaces 8 with pieces of wood in the vertical position 9, the ends of which have a tail joint. Described in pat.hak. 780165. If the above structure is insulated in 11 cavities with inflatable pulp wool after the logs are installed, the problem is likely to be the tendency of the inflatable 2 97906 insulators to sink over time, so that an air gap may remain in the top of the walls. The gripping surface between the boards and the pieces of wood connecting them is small, so the movement due to the life of the wood can detach the pieces from each other.

The structure disclosed in patent 75207 (in which a box-like beam made of four boards is connected at its corners by a metal full-length nail plate-like connector profile) is not suitable as a log wall structure because the longitudinal metal connector profiles connecting the boards make it possible to make and cut corner posts. In addition, a log-sized connector profile attachment is significantly more expensive than a tongue-and-groove attachment.

15

Pending Applications. In the structure known from 934644, the small elements are constructed of wooden boards, which are separated by spacers between the boards. Wood panels on the outer surfaces are fastened to the spacers with screws or nails, as in 20 elements in general. This method of fastening is not suitable for logs. to the structure because the screws or nails remain visible.

•. Patent 70965 discloses a log structure consisting of two outer panels and longitudinal spacers connecting them. To ensure the cohesiveness of the structure, · the element must be filled with polyurethane or some other adhesive insulating material. This is in stark contrast to the ecological principle of log construction.

: 30 Utility in model re-wrapping. 1420 has been resolved. the ecological problem of patent 70965. It has replaced the glue with a log length of \ log length. the production technology is likely to become a problem, a test of the tail joint groove: * milling is slow. In addition, inserting a tree several meters long into the joint groove can be difficult, as the boards are usually threaded. The two intermediate 3 97906 trees in the structure increase the price and impair the thermal insulation capacity.

The log element according to the invention eliminates the above-mentioned drawbacks. To achieve this purpose, the log element 5 is mainly characterized by the fact that each side of the intermediate board (2) has ribs transverse to the plane of the intermediate board, directed to each side of the intermediate board. the above-mentioned structure of the rib-groove joint enables an inexpensive warm wall structure, the manufacture of which is simple and fast.

An embodiment of the invention is shown in the accompanying drawing 1. Section λ-λ, which shows a vertical sectional view of a log wall, with the logs mounted one on top of the other. The log element is made of two pre-planed log boards (1) and a connecting lock board (2) connected to them, which are glued (or nailed) together into an open housing. After isolation, the log is notched. Solid wood (4), cut B-B, is glued to the ends of the log (between the boards). This results in a ready-to-install log that meets the thermal insulation requirements for the outer wall, has a breathable structure and: in addition, the log is made impressive due to its thickness. When installing hire, graves with the heart side facing outwards are blocked from the outside. cracking.

On the construction site, the logs are installed with saunas like planed logs in general, but it is not necessary to install a separate joint wool between the logs, because the pulp has been sprayed a little oversized. If necessary, a rubber-5 bait can be installed in the joint seam to prevent airflow from the log seam.

The partitions can be left uninsulated, so the HVAC installations can be pulled in the cavity, the logs of the partitions can be made of a thinner log lamella and a narrower lock lamella, so less raw material goes into the partitions and they take up less space »» · »• · 1 ·
