Description

The utility model relates to the field of construction, in particular to wooden housing construction, and can be used as the corner joint of the timber walls of a wooden building.

A known type of joint is angular, wooden block-like and timbered walls in a “paw”, in which the end part of each angular element of the joint is formed by vertical and inclined surfaces. This type of connection is characterized by compact dimensions as a result of the absence of parts of the bar protruding beyond the walls, but it has significant drawbacks. Elements of an angular connection with inclined forming surfaces cannot be manufactured on machine equipment intended for mass production. The corner joint does not provide structural strength, and therefore it is necessary to use additional fasteners such as wooden dowel or metal equivalent. Corner connection does not provide the necessary thermal properties, and therefore requires additional thermal insulation, for example, caulking gaps, as well as sealing the entire surface of the outer corners (GOST 30974-2002. Interstate standard. Corner connections of wooden block and log low-rise buildings. Table 1. Type compounds in the "paw").

Known shortened angular design, characterized by compact dimensions as a result of the absence of protruding parts of the bar outside the walls. Outside, the shortened design is closed with angled planks and a windproof material. At the outer end surfaces of the parts, there are depths of 2-3 cm. Thermal properties are provided by linings, corner beams and insulating windproof material. The disadvantage of the design is the low strength of the corner joint of this type and the complexity of installation with the use of windproof material (RU 79303, Е04В 2/70, publ. 27.12.2008).

Known smooth angular design containing tongue and groove joint, fastening the bars are connected at an angle to each other in the horizontal direction. The first beam contains a tongue-and-groove connecting element extending along the entire height of the beam, and the second beam contains the corresponding groove connecting element extending along the entire height of the beam, forming a dove-tail connection. The corner joint of the bars is made on the same vertical plane, without “bandaging” the bars of one and the other wall, and therefore does not have the strength of the lock corner joint. Thus, the disadvantage of the angular design is the low strength of the joints of the bars and the complexity of the design, which requires high precision manufacturing (RU 2630319, publ. 07.09.2017)

Known angular connection for the house in the four-sided lock groove, contains a cut-in "flush". The corner joint provides for the “remainder” of the timber protruding 100–200 mm beyond the outer surface of the log walls. As a result, the material consumption increased by an average of 4%. (RU 131395, publ. 08/20/2013).

The closest is the corner joint of wooden block and log walls of low-rise buildings, from which the type of joint is known in the four-sided lock groove (in the "Oblo"). The corner joint contains parts that form walls at an angle to each other with the mutual displacement of parts of one wall relative to parts of the other wall at half the height of the beam, provided with upper, lower and side grooves located on the inner and outer side at a distance from the end sections of the parts, limiting the end protrusions, thus forming the remainder of the beam (the release of the end protrusions of the beam) protruding beyond the outer surface of the walls by 100 ... 200 mm. Grooves of bars and profiled logs may have ridges, grooves and grooves (including under gaskets) designed to increase the density of joints (GOST 30974-2002. Interstate standard. Corner joints of wooden block and log low-rise buildings. Table 1. Four-sided joint type locking groove (in "Oblo")).

The disadvantage of the technical solution is not rational consumption of the material of the timber. For example, for a part with a length of 5 m. The consumption for the production of a bar will be 4% of the volume of the bar. In addition, protruding timber outside the walls occupies a volume and adversely affect the appearance of the object.

The objective of the claimed utility model is to save the timber and improve the aesthetic properties of the corner joint.

The technical result achieved in the implementation of this utility model is to reduce the consumption of timber material, the exception protruding beyond the walls of the parts of the timber, and increase the usable floor space of the building.

To achieve a technical result, an angular joint of a timber for the walls of a wooden building was proposed, comprising wall-made details made of timber that are angled to each other with the first wall’s relative displacement of parts of the second wall half a beam height, provided with upper, lower and side grooves, located on the inner and outer side at a distance from the end cuts, limiting the end protrusions, characterized in that the depth of the outer lateral grooves is greater than the depth of the inner the lateral grooves, the dimensions of the length and width of the end protrusion of the parts of the first wall are equal to the dimensions of the depth and width of the outer groove of the details of the second wall, the dimensions of the length and width of the end protrusion of the parts of the second wall are equal to the dimensions of the depth and width of the outer groove of the details of the first wall the first wall is smaller than the width of the end protrusion of the second wall parts by an amount equal to the size of the depth of the external groove of the first wall parts.

According to the utility model, the depth of the outer side slots is 0.25-0.29 of the width of the beam.

According to the utility model, the depth of the outer side grooves is 40-70 mm.

According to the utility model, the depth of the outer side grooves is 50-58 mm, and the width of the beam is 200 mm.

The utility model is illustrated with illustrations.

FIG. 5 angular connection of a bar assembled.

The corner joint of the timber for the walls of a wooden building contains parts 1 and 2 (Fig. 1), forming the first and second walls at an angle to each other. The angle between them is mostly 90 °. The sides of parts 1 and 2 (as well as the sides of the walls) facing the 90 ° angle are called the inner side. The other side of the parts, the opposite internal, is called the external side. The size of the distance between the inner and outer side of the beam is the width of the beam, as well as the thickness of the walls (not shown in the illustration).

Parts 1 and 2 are made of rectangular type timber with flat surfaces, or of profiled type with longitudinal ridges and grooves on the upper and lower surfaces. Parts 1 are identical to each other in the part of the corner joint, as are parts 2. Parts of one wall are placed with a mutual displacement relative to the details of the other wall by half the height of the beam. The parts are provided with upper 3, lower 4 (Fig. 2) and side grooves 5, 6, 7 and 8, located at a distance from the end slice 9 and 11. The end part of the part 1 from the end slice 9 to the groove 7 and the end part of the part 2 from face cut 11 to the groove 6 form the end protrusions 10 and 12 (Fig. 1)

The end protrusion 10 has dimensions of length c1 and width d1.

The end protrusion 12 has dimensions of respectively e2 and f2.

The side groove 5 of the outer side of the part 1 has dimensions of depth e1 and width f1.

The lateral groove 6 of the outer side of the part 2 has dimensions of depth c2 and width d2.

The dimensions c1 and d1 of the end protrusion 10 are equal to the sizes c2 and d2 of the groove 6, and the dimensions e2 and f2 of the end protrusion 12 are equal to the dimensions e1 and f1 of the groove 5. The size d1 of the end protrusion 10 is smaller than the size f2 of the end protrusion 12 by an amount equal to the size e1 of the external depth groove 5. In this case, the lateral surface of the end protrusion 12 is located on the outer side flush with the outer lateral surface of the beam 2, which as a whole ensures that the groove 5 is filled and the flat forming surfaces of the angle are formed.

The size of the depth of the grooves 7 and 8 of the inner side in the claimed and in known structures is approximately 16-32 mm. This size is determined on the basis of the dimensions of the cross-section of the beam and the design of the castle connection.

The dimensions of the length c1 and e2 of the end protrusions are equal to the dimensions of the depth of the corresponding lateral grooves c2 and e1. The length dimensions c1, e2 of the end protrusions 10 and 12, and the equal dimensions c2 and e1 of the depth of the groove are increased to a size that ensures sufficient strength of the end protrusions 10 and 12 from splitting along the wood fibers. However, an excessive increase in the size e1 and c2 of the depth of the grooves leads to a decrease in the size of the cross section and loss of strength in the area of the slots 3, 4, 5, 7 parts 1 and 3, 4, 6, 8 parts 2. Therefore, the ratio of the sizes of the slots 5, 6 and the dimensions of the end protrusions 10, 12 are mutually balanced to ensure strength.

According to the fabricated samples of the corner joint of the timber and the results of the experimental design, it was established that the depth e1 and c2 of the lateral grooves 5 and 6 facing the outside is 0.25-0.29 of the width of the timber.

It has been established that the preferred size of the beam width for a given corner joint is from 160 to 280 mm. The size c1, e2 of the length of the end protrusions and the equal dimensions e1 and c2 of the depth of the lateral grooves are in the range of 40 to 70 mm.

It has been established that for a beam width of 200 mm, the optimum size c1, e2 of the length of the end protrusions and equal dimensions e1, c2 of the depth of the lateral grooves are 50-58 mm.

For assembling the corner joint with offset of parts 1 of one wall relative to details 2 of the other wall half the height of the beam, part 13 is used (Fig. 4 and 5), which represents the upper half of the part 1 sawn along the longitudinal horizontal plane. This part is usually referred to as the zero bar.

The corner joint assembly is covered with protective and decorative elements 14 (FIG. 5), protecting it from weathering and giving the appearance of the object. Shelter has a positive effect on the thermal properties of the corner joint and the durability of wood.

The manufacture of parts for the corner joint is made, according to the design dimensions, includes the operations of trimming a bar-shaped workpiece and milling the grooves by feeding the cutting tool in the horizontal and vertical directions, in one or several passes of the tool. Hundegger K2i equipment or other equipment with similar functional characteristics, which is widely used in the manufacture of wooden house-building products, is used for manufacturing.

In the zone of the second end section, the parts may have a design of a similar form, to form a second corner joint, or another form, for example, for openings or for other structural or architectural elements of a building.

The assembly of the corner joint is made by the traditional method, by laying a zero bar 13, then a bar 2, then a bar 1, a bar 2 and so on. During the assembly, the sealing material is laid in the corner joint, as well as between the rows of parts 1, 2, if provided for by the project.

The corner joint of the timber provides high strength of the interlocking connection of parts and good thermal performance.

As a result of the equal size of the end protrusions 10, 12 and the size of the outer side grooves 6, 5, a reduction in the consumption of the beam by 4% is ensured. The corner joint at the same time forms an angle without protruding outward walls of the timber.

The corner joint is especially effective for building planning solutions whose walls form ledges or protrusions. At the same time, the absence of timber outlets outside the walls in the internal rooms provides an increase in the useful area of the rooms.

In addition, the location of the end protrusions 5, 6 within the surface of the wall allows you to cover the corner with decorative protective materials using simple technical means to ensure the rational form of the corners.

According to this technical solution, LLC “GUD VUD” carried out experimental development, made samples and determined the optimal parameters of the corner joint. The expediency of the use of products under this proposal was confirmed, technological preparation for its production is being carried out.
