RU2293161C1 - Wooden building of profiled beams - Google Patents

Abstract

FIELD: building, particularly wooden structures of profiled beams.

SUBSTANCE: wooden building comprises double-length beam of square cross-section. The beam comprises installation slots formed in each beam side and mating member, which provides connection of the same beam lengths to previous one. The mating member is formed as board with support projections on one board side. The projections define trapezes in cross-sections, which provide plane and inclined surfaces alternating during serial beam stacking. Mating member having greater length is laid on beam with lesser length and corresponding beam width having corner and other connections. Next beam is laid on mating member having the same length.

EFFECT: increased reliability of beam tightness and junction with each other in corner and other connection areas without transversal member forming at beam ends.

Description

The invention relates to the construction industry and the woodworking industry, in particular to the production of buildings for various purposes from profiled timber.

A known group of profiled structural beams, for example a beam (RF patent 2239028 7, E 04 B 1/10 from 03/05/2003), having a trapezoidal profiles in cross section.

The disadvantages of the known beam include the complexity of manufacturing, assembly and a limited number of options for the construction of various buildings due to the processing of transverse profiles with the necessary precision shape to ensure the conditions of congruency of the joining of the angular conjugation of long bars.

As a prototype, the method of erecting the walls of prefabricated log or timber houses and the prefabricated wall (RF patent 2044842 6, E 04 B 2/00, E 04 C 2/12 of 09/27/1995.), Consisting in the execution of a beam or log of two lengths, stacked on top of each other, drilling holes in them and tightening them with screw joints.

However, this method does not provide stable tightness of the walls and angular mating due to the need for periodic tared tightening of the nuts of the screw joints during operation of the building.

Thus, the task to which the claimed invention is directed is to ensure a snug fit and reliable fixation by bars by joining the bars with each other during the formation of angle-forming and other joints without making special transverse profiles at the ends of the bars that form a “lock” when joining.

This task is achieved by the fact that, having a trapezoidal profile in the cross section, the beams are equipped with a mating element in the form of a board with a trapezoidal cross-section profile on the side, which is laid longer with a shorter length and the mating width of the beams, and the beam on the mating element of a similar length.

Comparative analysis with the prototype shows that in the claimed technical solution, each bar having mounting grooves on one side is equipped with a mating element with supporting protrusions of a similar profile, resting on inclined surfaces when mounted on each other, connected by a tight screw connection during installation.

Thus, the claimed structure of a profiled beam meets the criterion of "novelty."

Comparison of the claimed structure with other technical solutions and methods of erecting wooden structures shows that the manufacture of a beam with a trapezoidal cross-sectional profile and various options for erecting building structures from it are widely known, however, the presence of an additional input structural element of conjugation in the combined relationship of the known elements creates the effect of quantitative and high-quality manufacturing and construction of buildings from long profiled bars of different lengths, at rarely stacked on top of each other, it is not known that in combination with the square design of the beam with installation grooves, and the interface element in the form of a board with support ledges confirms a new property, namely the factory workmanship and the ability to quickly erect a structure with a tight fit of the bars to each other and their reliable screed by screw connection in angle-forming and other mates without producing profile transverse elements on the edge of the beam.

This allows us to conclude that the declared structure of the profiled timber meets the criterion of "significant differences".

The drawings show:

figure 1 is a schematic diagram of the construction of angular conjugation of the wall of the house;

figure 2 is a cross section of the components;

figure 3 - option, timber, compiled in the factory;

figure 4 is a section aa in figure 3.

In the general case, the workpieces are dried and processed in a wood drying and impregnation plant. Free and bound moisture is extracted from wood by repeatedly repeating vacuum-pulse vacuum. The formation of the beams of the beam and the mating element is performed on the machine for deep longitudinal single-pass milling by the upper and lower tool spindles with conical twin mills. The beam 1 is made of a square length L ₁ and L ₂ with the same side B, on two opposite sides of which a groove 2 for installing the sealing element 3 and two trapezoidal mounting grooves 4 are made. The square section allows you to simplify the processing of profile elements, for example, a screw with left and right threads easy to change the position of the knives of the processing tool, i.e. readjust the sides of the square to a different value.

Each beam is supplied with a structure that is attached to it when mounting the structure by means of a 5 screw connection with an offset. In the connecting element 6, depending on the order of the crown, L ₁ and L ₂ in length, made in the form of a board with two trapezoidal supporting protrusions 7 on one side with a correspondingly alternating flat support and inclined surfaces during their successive laying. This embodiment provides the simplicity and quality of angular and other conjugation. The beam 8 is made for the lower crown of a rectangular section with a width of B and with a groove 2.

One of the possible options for the construction of the structure is shown in figure 1. The finished bars 1, 8 and the connecting elements 6 of two lengths connected to them are laid in an alternating sequence, namely the element 6 of length L _{2 is} laid on the length L ₁ and the mating width B forming the angular connection of the bars 1 or bars 8. After the alignment of the angle, drill holes through in the elements 6, the mates and the deaf in the bars 1 and 8 and tightly put the nagil 5 in them, fixing the position and interconnecting the bars 1 or 8 with each other, since they are interconnected. The second row of bars 1 is laid on the elements 6 with the coincidence of their lengths, placing the mounting grooves 4 on the inclined side surfaces of the support ledges 7. The assembly process is repeated until the formation of the upper crown of the wall. Then the ceiling is laid and the roof is installed by any known means.

In the case of the construction of the structure from the timber shown in figure 3, compiled with element 6 in the factory or on a specially designated site, the process is carried out according to the above technology.

Thus, the factory quality of the constituent parts of the structure in combination with the above method of quickly erecting the structure from profiled timber 1 ensures its tight fit and reliable screed with a 5-pin joint of angle-forming and other joints.
