Electric connection log structures

 

(57) Abstract:

The invention allows to simplify the process of making electric connections and to expand the raw material base for the production of timber structures due to the fact that, in at least two rows of wooden elements each of the elements in the row provided with at least one longitudinal groove of the same N-shaped in the upper parts of the element with three contact surfaces in the form of planes. 3 C. p.

The proposal relates to the construction of houses, buildings and constructions of log structures and can be used in the walls of these structures.

Electric connection is usually performed in the form of a longitudinal groove on one or two opposite sides of the logs and can have different shapes, for example a longitudinal groove in the arcuate shape [1]. Other forms: triangular groove "a" or with a comb "b" (see Fig. 16) [1].

Closest to the proposed form of connection is electric connection according to the patent [2].

Well-known compound, was adopted as a prototype, has at least two rows of wooden elements, each element in the row at the top and bottom parts with longitudinal p is raised, two of the three contact surfaces made in the form of an arc, because the processing of such a surface requires a complex cutting tools - milling cutter.

The objective of this proposal is to simplify the process of making electric connections, as well as the expansion of raw materials manufacture of wooden structures.

The problem is solved: the fact that electric connection log structures containing at least two rows of wooden elements, each element in the row at the top and bottom parts provided with at least one longitudinal groove of the same shape with at least three contact surfaces, a longitudinal groove is made N-shaped, and each of the contact surfaces in the form of planes;

- the fact that each element in the row is made of semi-log (plates), with their diametrically flat surface in adjacent rows are directed in different directions;

- the fact that one row of wooden elements made of composite of two semi-log, directed diametrically flat surfaces in different directions, and the other from whole logs;

- the fact that each element in the row is made of timber sector 240oC.

General principianti elements, each of the elements in the row at the top and bottom parts provided with at least one longitudinal groove of the same shape, at least three contact surfaces.

Distinctive features of the proposed design are the following symptoms. A longitudinal groove is made N-shaped, and each of the contact surfaces in the form of planes. This form of a longitudinal groove may be executed in the most simple tool, such as a circular saw, then as to produce longitudinal groove Z-shaped prototype, which two of the three contact surfaces made in the form of an arc, requires the use of more complex tools, such as cutters.

Another difference is that each item in the series, equipped with a N-shaped longitudinal groove, can be made of the half of the log facing flat surface at one side and adjacent the opposite. This embodiment contributes to the expansion of raw materials, for example in the case where the diameter of the available logs considerably more than is required for the construction of the building.

In the known technical solution prototype of such a variant is not prevnum of the two folded halves of the log, and another from a log. This embodiment provides a self sealing connected elements, low insufflation and waste reduction, because it doesn't require surgery, Ocharovanie provides a clean wall surface on both sides, close to the surface of the timber. The known solution does not provide such option.

The next difference is that each element in the row is made of log sector with angle 240owhile the semicircular surface directed upwards. This embodiment has a low insufflation and, in addition, this form of execution reduces the likelihood of moisture in the connection.

Known technical solution does not provide such an option run.

Therefore, this proposal meets the criteria of the invention of "novelty."

For comparison of proposals with other known solutions conducted a search of the patent and scientific literature. Known electric connection log structures including longitudinal triangular groove (Fig. 16"a") [1] or quadrangular groove and attached block of the same shape on the opposite side (Fig. 16 b). Each of the contact surfaces, which provides only two contact surfaces, while the proposed design is at least three.

A disadvantage of known construction with a rectangular groove is that it has an additional fastening element is attached to the bar.

The disadvantage of both variants of known construction is that they do not provide a solid connection of two or more elements in a series. In the proposed embodiment, such a disadvantage does not.

Thus the proposed connection meets modern technology.

The proposal is illustrated by drawings, where Fig. 1 shows a General view of the connection from whole logs; Fig. 2 is a variant of the connection of the semi-log (plates semicircular shape) of Fig. 3 is a variant of the connection of the two semi-log in the same row and whole logs in the other; Fig. 4 is a variant of the connection of the sector 240o.

Ironman compound contains at least two rows of wooden elements - the top 1 and bottom 2. Each of the elements in the row provided with at least one longitudinal groove in the top 3, and 4 in the lower part of the same shape.

A longitudinal groove 3 and 4 has at least three contact surfaces 5, 6 and 7 N-shaped, made in the form plasketes round-edge cant 8, 9 (Fig. 2), with their diametrically flat surfaces 10, 11 are directed in different directions, according to their semi-circular edged surfaces 12, 13 are also aimed in different directions.

In another embodiment, the connection can be made so that one row of wooden elements made of composite of two semi-log 14, 15, directed diametrically flat surfaces 16, 17 to the outside (in different directions), and the other the number of whole logs 18 (Fig. 3).

In the following embodiment, the connection is made in such a way that each element in the row is made of timber sector 19, 20 with the angle 240othis semicircular surfaces 21, 22 are directed upward.

The proposed solution can be illustrated, and other similar variants. A characteristic feature of all these options is that each element in the compound provided with at least one longitudinal groove in the top 3, and 4 in the lower part of the N-shaped.

The presence of the specified longitudinal groove simplify the manufacturing process of the connection by providing the possibility of using the most simple tools, such as circular saws, improves the tightness of the connection due to A use of material of different diameters, in addition, the presence of a longitudinal groove provides a strong connection between the elements.
