Description

The utility model relates to the field of ground construction, and more specifically to the exterior decoration of the corners of log or paving buildings, and can be used mainly when cornering by cutting into a “bowl” or cutting into a “paw”.

The device of the corners of the walls of buildings obtained by cutting in the "cup" (with the remainder) and cutting in the "paw" (without the remainder) are widely known. [A wooden house from small to large. Series "House". - M .: "The cognitive book +", 1999. - 184 p. (Page 56, Figure a, b)]. When cornering the walls of wooden buildings into a “bowl” (with the remainder), the building element (log, beam or glued beam) has the necessary grooves for fastening with subsequent elements, and part of it goes beyond the corner. When cornering the walls of wooden buildings in a “paw” (without residue), the building element (log, beam or glued beam) is limited to fastening with subsequent building elements and does not protrude beyond the corner. In such structures, corner joints are a vulnerable point, since the ends of logs, beams or glued beams are not closed from external environmental influences (rain, sun, wind, etc.) and freezing is possible in the corner of the walls (because here lower temperature than on the smooth wall).

To protect the outside corner of the log house “from the paw” from weathering, they are lining the boards (“Subtleties of building chopped wooden houses: log house according to the rules (Rules and errors in assembling log cabin handcuts)”, seversrub.com> page.php? Id = 108) . The design does not take into account the shrinkage of the building, and in the first years of operation, destruction of fasteners or attachment points may occur.

Angular external siding structures are known ("Installing the external siding angle", sading.net> narush.html). The design of the siding consists of overlapped lapped or with the help of overlays of corner profiles with a nail strip fixed to the walls of the building. When mounting the indicated corner structures, it is required to strictly observe the rule: leave a temperature gap between the nail strips of the corner profiles and maintain an overlap of 2-2.5 cm over the overlays. This complicates the facing of the corner of the building. In addition, when joining corner profiles with the help of overlays, it is possible that moisture can enter the structure. The installation of a large-angle angle from a single vertical profile is very expensive, and the joining of profiles greatly complicates the implementation and reduces the tightness of the entire structure.

The closest technical solution for the claimed utility model according to the first embodiment is an airtight log corner construction according to the patent for utility model No. 79303, IPC E04B 2/70, the embodiment shown in FIG. 4. The ends of the logs of the first wall and the ends of the logs of the second wall in the corner connection do not protrude beyond the level of the outer surfaces of the walls (log house assembly “without residue” or “into the paw”), forming a shortened angular structure. On the outer surfaces of the ends of the logs there is an end thinning, which ends at the edge, the distance to which from the outer corner is greater than the width of the log in the end thinning. Windproof paper is attached to the outer surface of the corner from the edge of the end thinning of the first wall to the edge of the end thinning of the second wall, and windproof paper is attached on top of it. Outside, the corner structure is closed by vertical overlays (slats), some ends of which are fixed on boards located directly in the corner of the structure and the second are extended beyond the edges of the end thinning and attached to the outer surface of the logs, overlapping the gaps at the intersections of the logs. The design of the prototype is designed for wind protection of the ends of the logs, as well as protection from weather loads and to prevent the ingress of water and wind into the gaps and seams of the corner joints. However, this known device has a shortened length, a plurality of connected parts and fasteners, which leads to insufficient protection against moisture in the structure. With a large flow rate of precipitation, windproof paper or cardboard in the structure can get wet and cause the development of fungi and contamination of the wood of the log.

The design does not take into account the shrinkage of the building, and in the first years of operation, destruction of fasteners or attachment points may occur. The closest technical solution for the claimed utility model in the second embodiment is an airtight log corner construction according to the patent for utility model No. 79303, IPC E04B 2/70, the embodiment shown in FIG. 5. In this embodiment, the ends of the logs of the first wall and the ends of the logs of the second wall in the corner connection slightly protrude beyond the level of the outer surfaces of the walls (assembly "in the bowl"). The device contains three corner pads in the form of boards fixed in the corners formed by logs intersecting in the corner and windproof paper located on the outside of the corner under the pads. Outside, the angular structure is closed by overlays in the form of strips, one ends of which are interconnected, forming a rectangular angular profile. Planks are placed on the ends of the logs and onlays from the boards and cover the gaps between the logs, preventing water and wind from getting through them. However, this known device has a shortened length, a plurality of connected parts and fasteners, which leads to insufficient protection against moisture in the structure. With a large yield of precipitation, windproof paper in the structure can become wet and cause the development of fungi and contamination of the logs. The design does not take into account the shrinkage of the building, and in the first years of operation, destruction of fasteners or attachment points may occur. The use of this protection design is limited by the angular design with the lengths of the ends of the log elements not more than 4 centimeters.

The objectives of the utility model for both options are to protect the ends of the logs, beams or glued beams from external environmental influences (rain, sun, etc.) and increase the heat-shielding properties of the structure.

The technical result, which is claimed by the claimed utility model for solving the problem of the first and second options, is to exclude the possibility of moisture penetrating into the corner structure, to exclude the effects of ultraviolet rays on the insulation, to increase the heat-shielding properties of the building corner structure.

The technical result is achieved as follows.

According to the first option, the utility model has in common with the prototype that it contains external linings fixed to the log elements connected “in the paw” and overlapping the ends of the logs or timber.

Unlike the prototype in the utility model according to the first embodiment, the external overlays are made in the form of angular rectangular profiles and are joined to each other along the height of the building using a tight groove-protrusion connection, while the lower protrusion of each corner profile is located on the outside of the structure and overlaps the upper the protrusion of the underlying angular profile with the formation of gaps from the ends of the protrusions 1 ± 0.2 cm

According to the second option, what is common with the prototype of the utility model is that there are external overlays fixed to the protruding ends of the log elements connected “into the bowl” and overlapping the gaps at the intersections of the elements.

In contrast to the prototype, the outer pads in the utility model according to the second embodiment are made in the form of angular profiles and are joined to each other along the height of the building using a tight groove-protrusion connection, while the lower protrusion of each corner profile is located on the outside of the structure and overlaps the upper protrusion the underlying angular profile with the formation of gaps from the ends of the protrusions 1 ± 0.2 cm

The angular profiles according to the second embodiment in cross section may be rectangular or have a trapezoid shape, the sides of which are located on the protruding ends of the log elements. The ends of the side faces of the corner profiles are bent over the protruding ends of the elements of the log house. The cavity formed between the corner profiles and the outer corner of the building, in the second embodiment, is filled with insulation, such as polystyrene foam. The use of this design to protect the angle is possible with any length of the ends of the log house elements.

Corner profiles for both options are made of plastic, or metal, or of wooden panels impregnated with a bactericidal composition, for example, copper sulfate solution, and glued together with a high-strength moisture-proof adhesive, for example KLEIBERIT PUR - adhesive 501.

The implementation of the outer lining in the form of finished corner profiles and the location when docking them from the outside with a lower ledge, i.e. face down, to prevent the penetration of moisture into the building, provide protection from atmospheric influences and increase the heat-shielding properties of the structure. And the use of additional insulation (the second option) enhances the heat-shielding properties of the device.

The presence of vertical grooves and vertical protrusions in the connection of the corner profiles ensures their reliable connection, the integrity of the mounted structure and prevents it from moisture and deformation during shrinkage of the building, since the corner profiles are joined with a gap of 1 ± 0.2 cm.

Both variants of the utility model are united by a single creative concept, since they are aimed at achieving the same technical result in the same way: the use of corner profiles to protect the corners and connecting these profiles in height by the “groove-protrusion” type, with the lower protrusions being closer to the outside . The essence of the utility model is illustrated by drawings.

Figure 1, 2, 3 shows the angular structure of the building, made by the method in the "paw" (without residue) of logs, beams and glued beams, respectively (the first version of the utility model).

Figure 4, 5, 6 - angular structure of the building, made by the method in the "bowl" (with the remainder) of logs, beams and glued beams, respectively, with an angled trapezoidal profile (second version of the utility model).

In Fig.7, the cross section of the angular structure in plan according to the second embodiment with an angular rectangular profile.

In Fig. 8, the same as in Fig. 7 with an angled trapezoidal profile with bent ends.

In Fig.9 is a section 1-1 of Fig.7 and Fig.8 (connection of angular profiles in thickness), where Ext. - the inside, Nar. - the outer side of the corner profile.

The angular design in both versions contains angular profiles 1, mounted on wooden elements 2, 3. The connection of the angular profiles to each other is performed according to the “groove-protrusion” type with the lower protrusion located closer to the outside to prevent moisture ingress and the possibility of high-quality connection when the building shrinks (Fig.9). When performing the corners of the walls of wooden buildings in the "bowl" (with the remainder) (Fig. 4, 5, 6) between the corner profile and the outer corner of the building, a cavity 4 of rectangular (Fig. 7) and triangular section (Fig. 8) is formed, which can fill with insulation, for example polystyrene foam.

At the ends of each angular profile, protrusions 5, 6 and grooves 7 are made. The ends of the protrusions 5, 6 are installed in the grooves 7 with a gap 8 of 1 ± 0.2 cm. The angular profile can be made of wood, plastic and metal.

The utility model is industrially applicable. In both versions, for joining angular profiles from wood, vertical grooves 7 and protrusions 5, 6 at the ends of the angular profiles can be obtained by reducing the thickness of the profile by 2 times and ensuring their necessary depth. In both versions, for joining the corner profiles of plastic and metal, the grooves and protrusions at the ends of the corner profiles are performed in advance in their manufacture. For the manufacture of corner profiles made of wood with grooves and protrusions, the use of tape and milling machines is possible. On milling machines, grooves are made with a width of 0.5 profile thickness and 2 centimeters deep. The grooves at the opposite ends of the angular profile are staggered. When using wooden panels, they are pre-glued together with a high-strength moisture-proof adhesive, for example KLEIBERIT PUR-adhesive 501. Before gluing, each individual panel is first dried and treated with fire-retardant and water-repellent compounds. They are impregnated with a bactericidal composition (solution of copper sulfate). For the manufacture of plastic plates using a stamping machine. For the manufacture of blanks of plates from sheet metal using guillotine shears. The creation of the necessary configuration of the metal panel is performed using a roll forming machine. Drill holes are made in the plastic and metal plates with drills. The fastening of the corner profiles on the corner structure is carried out with nails, dowels or screws with rubber washers. The fastening of the first profile starts from the bottom point of the angle, and the next profile in height is performed as follows: the lower protrusion 5 of the upper corner profile is placed on the outside of the structure and overlap the upper protrusion 6 below the lying corner profile with a gap 8 of 1 ± 0.2 cm. With this method of joining, the end face of the protrusion 5 is directed downward, and moisture does not enter the structure, and the gap prevents deformation of the cladding structure when the building shrinks.
