Description

The utility model relates to the field of construction, in particular to the seams (nodes) of the intervening connection of wooden house building to create a sealing system for the intervent space with increased heat / wind insulation properties, and can be used in wooden low-rise construction (residential / summer houses, bathhouses, garages, arbors etc.). The utility model is universal, and is applicable to all of the following types of building material: wooden beam; wooden shaped beam; wooden glued beam; round log - any wood moisture.

Currently, the most technically advanced construction companies use various rubber seals (EPDM) for wind / heat insulation of inter-crown joints, which are compressed during the laying of the next crown, thereby covering possible gaps. The disadvantages of this system are: large residual deformation of the sealing material (about 50% - according to manufacturers); short service life (about 5-10 years - according to manufacturers); due to low elasticity - the inability to ensure the tightness of the joint at high wind loads.

Many companies for wind / heat insulation begin to use self-expanding tape PSUL - (pre-compressed sealing tape). PSUL is made of foamed polyurethane, and its service life (according to manufacturers) is about 20 years. But practice shows that even after 5 years of the PSUL being in a compressed state (inside the interventional space), with the subsequent dismantling of the wall, the PSUL does not restore its original state. That is, PSUL cannot guarantee to fill the gaps arising from operational deformations of wooden elements. PSUL, also, cannot ensure the tightness of the joint at high wind loads.

A wooden element, such as a wall, is known in the art that is made in the form of a set of consecutive planks, for example, a transverse fold of boards, where each board contains a set of protrusions and / or a set of grooves on its longitudinal edges. The protrusions of one of the boards are adapted to interact with a plurality of grooves of another board. A seal is installed between each board in the groove or in the grooves of the groove and is made hollow of a flame-retardant elastomeric material, for example rubber (FR 2976302, 12/14/2012).

The disadvantages of this design include the following:

- The compression of the sealing element at the time of laying the next upper crown is created due to the forces of gravity, namely, the weight of the next upper crown should overcome the elastic properties of the rubber seal. For this reason, there are limitations on the elasticity of the used sealing elements due to the light weight of the wood. If sufficiently elastic sealing elements are used, the suspension (incomplete landing) of the next stacked crown occurs during installation. Therefore, weakly-elastic sealing elements are used, which, for the above reasons, cannot provide sufficient joint tightness at high wind loads.

- A linear dependence of the tightness of the joint on the degree of opening of the interdental joint (the larger the opening, the less the force of pressing the sealing element to the surface of the beam).

- Large residual deformation of the sealing material (about 50% - according to manufacturers).

- Not a long service life (about 5-10 years - according to manufacturers).

угла строения, угловое соединение строения выполнено стыковым с соединением торцов посредством шпонки и клея. По крайней мере одна грань каждого из брусьев, образующих поверхность внешней стены строения, и торцы брусьев выполнены с огнезащитным покрытием на основе алюмосиликатных микросфер и термопластичного полимерного связующего.Known profiled beam of rectangular cross-section, made with opposite faces, equipped with support protrusions and longitudinal installation grooves for placing the supporting protrusions of a similar beam when installing the beams on top of each other, having trapezoidal profiles in the cross section and with cuts in the installation grooves and / or supporting protrusions of the beam ( RU 101721, 01.27.2011). From the patent RU 126025, 03/20/2013, the structure of a profiled beam equipped with supporting protrusions and mounting grooves on its two opposite sides having trapezoidal profiles in cross section is known. In the installation grooves and / or supporting ledges of the beam, cuts are made. The walls of the building are assembled from alternating rows, consisting of one beam and two shafts of shorter length, connected by a key. Between the faces of two adjacent bars forming a wall, a soft insulation is laid, equal in length to a larger beam. The ends of the beam, forming the angle of the structure are sawn off at an angle equal to

angle of the structure, the angular connection of the structure is made butt with the connection of the ends by means of dowels and glue. At least one facet of each of the bars forming the surface of the external wall of the structure, and the ends of the bars are made with a fireproof coating based on aluminosilicate microspheres and a thermoplastic polymer binder.

These designs have several drawbacks. Since the manufacture of longitudinal cuts is carried out before drying the beam, and, possibly, before milling (profiling) the beam, it is quite problematic to observe the alignment of these cuts on the opposite mating surfaces of the finished profiled bars. As a result, the practical impossibility of dressing cuts in the upper beam on a wooden key installed in the cut of the lower beam when assembling the wall. In order for such a design to be feasible, it will be necessary to produce the key in advance weakened (smaller thickness than the cuts), which makes it a meaningless element in the design. A wooden key has a tendency to dry out, crack, rot, which also negates its purpose in the structure. Aluminum foil plates are almost impossible to use in this design due to the same misalignment of the cuts, and, as a consequence, the practical impossibility of putting the cuts in the upper beam on the foil plate installed in the cut of the lower beam when assembling the wall. In addition, aluminum foil has a permanent deformation, and will not be able to block possible gaps formed during the operation of the building. The only function of the foil strip in this design is to reflect infrared radiation (within its surface area) directed toward the wall.

A known seam of wall panels of building envelopes of buildings and structures, including a sealing mastic sequentially placed in the gap between the end faces of the wall panels, the sealing mastic from the outer surface of the panels, an elastic gasket and insulation, the gasket has a tubular shape and is made of wilaterm, the sealing mastic has a relative elongation of at least 20 %, and the insulation is a mounting foam (RU 90089, 12/27/2009).

The disadvantage is the high complexity with insufficient tightness and operational reliability of the seam.

A seam of the interventional connection of a log house is known, which is formed between the upper and lower crowns, and each log in these crowns has conjugate faces, including grooves and protrusions. In the grooves are placed sealing elements made of a polymeric material by extrusion (US 2008127583, 05.06.2008).

However, in this seam the above disadvantages are not eliminated.

The closest analogue of the claimed utility model is a seam of an intravenous connection, in which coaxial grooves are made in the mating faces of an interventional connection of logs, and to obtain a seam, the sealing element in the form of a calibrated profile is pressed with its one side into a longitudinal groove made on the underlying beam and the other side - it is tightened to a longitudinal figured groove made on an overlying beam during the combination of logs, and ensures tightness (US 2007006539, January 11, 2007).

In this design, as a sealant, a profile made of rubber based material (EPDM), or foamed polyurethane, or foamed polyethylene, etc., can be used technologically, therefore, it has the same drawbacks that are inherent in the joint known from FR 2976302, 12/14/2012.

The problem to which the proposed utility model is directed is to create a seam of an interventional connection that would eliminate the above disadvantages.

The technical result achieved by the implementation of this utility model is to increase the heat-insulating properties and airtightness for blowing inter-crown joints in the walls of wooden buildings while preserving the fundamentals of the technology for manufacturing the wall kit and assembling it at the construction site and with possible changes in cross sections and relative axial displacements of the longitudinal grooves .

The specified technical result is achieved in the seam of the interventional connection, containing a tight fit in longitudinal grooves having a coaxial arrangement on both conjugated faces of the interventional connection, a sealing element representing an elastically deformable calibrated profile and having an overall width greater than the width of the longitudinal groove.

The inter-crown connection can be wooden elements stacked on top of each other in a row, representing a wooden beam, or a wooden profiled beam, or a wooden glued beam, or a rounded log. These bars or logs can be made with supporting protrusions and longitudinal mounting grooves for placing the supporting protrusions of a similar beam / log when installing the bars / logs on top of each other.

A hollow profile of a polymeric material may be made at least single chamber.

The claimed utility model implements a sealing scheme for the interventional space using the seam of the interventional connection (additional heat / wind circuit “Interventional floating heat / wind shutter”: wind floating shutter and thermal floating shutter).

“Wind floating shutter” - is formed by installing a sealing element — a calibrated profile made of impact-resistant material (for example, sealing elements are a hollow extruded profile made of polymer material based on (PVC or polyethylene or polypropylene), or a full-body profile made of foamed PVC made by extrusion or casting) into prepared technological longitudinal grooves of a certain depth and specific width, made on both mating planes of the der sowing elements (crowns) in a strictly axial mutual arrangement. “Interventional floating heat / wind gate” (claimed technical solution) may have a single-circuit or double-circuit design. In the single-circuit version, the sealing element can be located anywhere in the interventional space: closer to the outside of the wall; closer to the inside of the wall, or in the center (axis) of the wall. In the double-circuit version, the sealing elements must be located inside the interventional space in two threads. The "Wind Floating Shutter" repeats the full contour of the outer walls of the wooden structure, and fills each interventional space along the entire height of the walls of the wooden structure. The sealing element is a calibrated profile, has an overall width — greater than the groove width — of the amount of elastic deformation of the side walls of the profile, taking into account its forced tight fit into the longitudinal grooves of the conjugated faces of the intervening connection (mating wall elements), which ensures complete protection against blowing through the interventional wall joints. The calibrated profile has an overall height calculated for a certain depth of grooves on the mating planes of the crowns, which, in turn, allows the profile to perform the functions of a “Wind Floating Lock” even with operational deformations of wooden elements in the walls with the formation of significant (up to 10 mm) interventional clearances without leakage of interventional joints in the wall of a wooden structure.

“Thermal floating shutter” - is ensured by low thermal conductivity (comparable with the thermal conductivity of a single-chamber double-glazed window filled with ordinary air) of a calibrated profile installed in the grooves of mating wooden elements.

The seam of the interventional connection is not a key, because the role of the key is to prevent the mutual displacement of the mating parts of the wall. In this case, the task of the calibrated profile is to be able to elastically deform (change the geometric shape - the cross section) with possible changes in the cross sections and the relative axial displacements of the longitudinal grooves in which it is located. For these purposes, the profile is made of an elastically deformable polymer material that meets these requirements (for example, on the basis of impact-resistant PVC, or foamed PVC, or polyethylene or polypropylene. Its service life exceeds the service life of wooden structures. Due to the elastic deformation of the side walls of the profile with a tight landing it in the grooves in the beam (log), - the force of pressing the side walls of the profile to the walls of the groove allows you to ensure the windproof node of the intervening connection, even with strong wind During operational deformations of wooden wall elements, the profile has the ability to shift (swim) into the groove in vertical directions (up / down), as well as change geometrically in the cross section, adjusting to possible mutual axial displacements of the grooves in the mating beams when they shrink and shrinkage, thereby leaving the knot locked against the penetration of the wind.

The cost of such a profile is comparable to the cost of an EPDM sealant, which does not affect the increase in the total cost of a wooden structure, but at the same time, the technical and operational indicators of the buildings being built are significantly improved.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a cross-section of the pairing of profiled bars ("Finnish profile") with sawn longitudinal grooves and installed in them

a profile performing the role of “Interventional floating heat / wind shutter”, with a jute laid in the interventional space, as well as visualization of the wall element; in FIG. 2 - cross-section of the pairing of profiled bars (“German profile”) with sawn longitudinal grooves and a profile installed in them, performing the role of “Interventional floating heat / wind shutter”, as well as visualization of the wall element; in FIG. 3 - cross-section of the pairing of logs with sawn longitudinal grooves and a profile installed in them, performing the role of “Interventional floating heat / wind shutter”, with a jute laid in the inter-crown space, as well as visualization of the wall element; in FIG. 4 - cross-section of the pairing of non-profiled bars with sawn longitudinal grooves and a profile installed in them, performing the role of “Interventional floating heat / wind shutter”, with a jute laid in the interventional space, as well as visualization of the wall element. Accepted designations:

1 - longitudinal groove;

2 - the upper crown of the interventional connection;

3 - the lower crown of the interventional connection;

4 - sealing element - calibrated profile;

5 - jute.

In the claimed utility model, a seam of an interventional connection “Intervent floating heat / wind shutter” is disclosed, in which a calibrated (shutter) profile is integrated into the interventional space of a wall assembled from elements (wooden beam; wooden shaped beam; wooden glued beam; round log) in this way that, during operational deformations of wooden wall elements, it has the ability to elastically deform, and freely displace (swim) in the grooves (similar to the compression ring in the groove p internal combustion engine) of the mating wall elements in vertical directions (up / down), and always (within the permissible displacement) provides a reliable barrier against the penetration of wind into the room, and also helps to maintain heat in the room in the cold season, thereby saving energy carrier.

The longitudinal grooves of the end faces of the interdental connection are made of calibrated cross-section in one technological operation together with milling (profiling) of a beam, a log that is logged, or sawn on a finished profiled beam, a log that has been cut using special equipment directly on the construction site, which ensures absolute accuracy in alignment of the grooves on opposite planes of wooden elements, which, in turn, positively affects the ease of assembly of walls on this system. The sealing element - the calibrated profile has low thermal conductivity, does not dry out over time, is not afraid of moisture, does not crack and is not subject to decay, while it has the ability to swim (move up / down) along the longitudinal grooves, therefore, it always ensures the same clamping force on the side walls, which does not depend on the size (within the limits of the possible (depends on the height of the applied profile)) disclosure of the interventional gap.

The wall using the seam of the interventional connection “Interventional floating heat / wind shutter” is assembled as follows.

After fixing the structure on the base of the lower crown 3, the sealing element 4 “floating heat / wind lock” is stored in the prepared longitudinal grooves 1 along their entire length (for example, with a wooden mallet) to the entire depth of groove 1. If the construction of the beam involves laying jute 5 (jute pads) then it fits. Then, another crown is laid on top, which, with its grooves located on the lower plane of the beam, technologically falls on the protruding part of the sealing element 4 of the "floating heat / wind shutter" stored in the lower crown 3. In order to completely fit the upper crown 2 into place, and to overcome the elastic deformation of the side walls of the sealing element 4 when it enters the grooves 1 of the upper crown 2, it is necessary to force the crown to be precipitated (for example, by means of manual ramming). Regular upper crowns 2 are stacked according to the same principle.

Installation of a building using a seam of an interventional connection “Interventional floating heat / wind shutter” does not differ in labor costs from installation using traditional technologies, but surpasses some in terms of manufacturability and convenience. For example, in systems involving the laying of a jute gasket in the inter-crown space, there is a danger of its shift during installation work, and pinching it between the mating crowns, which is an unacceptable violation of the technology of building construction. Installation with the claimed utility model excludes the existence of such a hazard, because the jute is placed between calibrated profiles of the “floating heat / wind shutter”, which have a decent protrusion height, and, thereby, limiting the possible lateral displacements of the jute during installation work.
