LT5986B - Proportion-retaining corner tenon jointpf square - Google Patents

Abstract

The object of the invention is a proportion-retaining corner tenon joint for square logs wherein square logs,joined perpendicularly in relation to each other,comprise upper tenon cheeks and lower tenon cheeks, incliened planes for next tenons, inclined planes for tenon necks, sealing gaps, compensatory surfaces, measuring surfaces and copying surfaces. In order to provide an airtight ant stable joint, the square logs have sealing edges located tetween the surfaces of the lower tenon cheeks and the compensatory surfaces. The said corner tenon joint for square logs keeps the cornertenons of log houses airtight regardless of the weather conditions. The joint allows constructing houses of partially dried logs where the corner tenons of perpendicular logs remain in tight contact with each other regardless of the moisture level.

Description

BACKGROUND OF THE INVENTION The present invention relates to the field of construction and provides corner joint joints used in the construction of log structures and log houses, where intersecting logs must be joined.

BACKGROUND OF THE INVENTION

There are many different angular stitch joints known, some of which are machine-made and some are hand-made. The most common machine made studs are saddle groove and trapezoidal joints. One example of such a connection is when the groove cut into each of the upper logs corresponds to the profile of the lower round log or beam. Alternatively, the joint structure may include recesses to be filled, or the notch elements may be fitted to ensure tightness. In the case of a trapezoidal joint, the inclined planes for the joint are cut on both sides of the log, upper and lower. When logs are stacked on top of each other, these joints also guarantee that the walls will remain mounted, even though there will be no overlap in the corners of the logs. The tools used are blocking grooves and anti-settling blocks made of wood core (US20090293390, Richard T. Anderson, 2009).

So-called Norwegian studs (JP 2009030419, R C KOA KK, 2009; EP0157161, Oertki Werkzeuge AG, 1985; US4287694, G. Howard Cornell, 1981) have been widely used in the construction of log houses. Also known are Norwegian studs, supplemented with a projection part extending from the groove element (VV02006121063, Anji Co Ltd, 2006).

There are also known wooden wall panels for timber frame houses whose edges include trapezoidal stud grooves; if it is necessary to connect such a plate to another plate, connecting elements corresponding to a trapezoidal groove are used, where the elements differ in their relative humidity content and due to the ambient air humidity, the panel elements and the fittings are joined into a common unit (EE00439U1, P. Moldow Filter Engineering).

The closest angular joint of a Norwegian tooth is provided by the invention described in U.S. Patent No. 4,287,694 (Cornell, G. Howard, 1981), but the joint described in that patent does not have surfaces which remain proportional to one another.

The currently known and used corner joints do not remain proportional to each other as the wood dimensions change.

The dimensions of the woody material in the field do not maintain a constant dimension (it maintains its moisture balance). Wood characteristics and dimensions change due to humidity, wind, sun and heat.

The manual production of junctions is time-consuming and labor-intensive.

Hence, log houses require corner joints that are air-tight, independent of changes in the wood dimensions of the building material, which occur perpendicular to the fiber under changing climatic conditions, and which can be manufactured quickly without the use of handmade but using machinery instead.

THE SUBSTANCE OF THE INVENTION

It is an object of the invention to provide an angled stud joint that maintains proportions. Corner stud joints in which the beams are perpendicular to one another include the upper stud sidewalls and the lower stud sidewalls, stud necks, stud stud bevels, neck stud bevel planes, sealing gaps, compensating surfaces, measuring surfaces, and coping surfaces. In order to ensure a tight and firm connection, the beams include sealing edges between the lower surface of the sidewall and the offset surfaces, and the angle between the offset surface and the cross-sectional surface of the beam is between 4 and 15 degrees, preferably 8 degrees. The angle between the upper surface of the sidewall and the cross-sectional surface of the beam and the angle between the lower surface of the side-walls of the beam and the cross-sectional surface of the beam is between 57 and 71 degrees, preferably 64 degrees. The angle between the inclined plane of the stud and the vertical lateral surface of the beam is between 7 and 17 degrees, and preferably 12 degrees. The upper side walls, lower side walls and offset surfaces are wedge-shaped. The copying surfaces and the compensation surfaces are perpendicular to each other and the measured surfaces are parallel to the cross-sectional surface of the beam. The distance between the copied surfaces is equal to the distance between the measured surfaces.

In the corner joint of the beams, the sealing edges of the upper beam press the sides of the upper beams of the lower beam in parallel, and the dimensions of the surfaces of the joints joined by the joint always remain the same, whether the wood expands due to moisture or shrinkage.

When the beams are expanding due to moisture, the sealing edges of the upper beam of the angular seam joint cut into the side walls of the upper tines of the lower beam.

When the angled logs shrink while drying, the sealing edges of the upper stud of the corner stud joint press against the side walls of the upper studs of the lower stud.

When the beam joints are expanded by moisture or shrink during drying, the inclined planes of the upper beam and the bevelled planes of the tines are shifted relative to the planes of the lower beam and the oblique planes of the tine.

The joint keeps the logs in the corner of the log home tightly sealed despite the climatic conditions. The joint also allows the installation of houses made of partially dried logs, as the angled studs of the crossed logs remain firmly pressed together, regardless of moisture content.

Compared to machine-made and manual-made solutions, the present invention improves the tightness of corner house junctions, reduces production time and reduces the number of machine operations and, ultimately, reduces the cost of production.

IMPLEMENTATION DESCRIPTION

The beams are machined with a milling machine, end and side milling machine to achieve a proportional angular joint.

After the beams are milled, they are joined to each other to form a perpendicular stud joint: upper stud side wall 2 and lower stud side wall 9, lower stud side wall continuous planes 7, studs 8, stud studs 5, studs beveled planes 6, offset surfaces 10, measured surfaces 4 and copying surfaces 3. The bars have milled sealing edges 1 between the lower stitch side wall surfaces 9 and the offset surfaces 10. To ensure a stable and tight connection, the angle is between the offset surface 10 and the cross-sectional surface of the beam is 8 degrees, the angle between the upper stud side walls 2 and the beam cross-section and the angle between the lower stud side walls 9 and the beam cross-sectional surface is 64 degrees, the angle between the tapering tapering planes 6 and the vertical the lateral surface is 12 degrees, and the angle between the inclined plane 5 of the cervical spine and the cross-sectional surface of the beam is 12 degrees, the upper spine side walls 2, lower spine side walls 9 and offset surfaces 10 are wedge-shaped and copying surfaces 3 and offset surfaces 10 is perpendicular, and the measured surfaces 4 are parallel to the cross-sectional surface of the beam, where the distance between the copying surfaces 3 is equal to the distance between the measured surfaces 4.

In the corner stud joint, the upper gasket sealing edges 1 are pushed parallel to the upper gusset side walls 2 of the lower girder, and the dimensions of the copying surface 3, the measuring surface 4, the tapering tapering planes 5 and the tapering tapering planes 6 always maintain their proportion. shrinks due to moisture or drying.

When the angular logs expand due to moisture, the sealing edges 1 of the upper beam intervene in the side walls of the upper stud of the lower beam.

When the beams are shrinking while drying, the sealing edges 1 of the upper beam remain detached from the side walls 2 of the upper beam of the lower beam.

c

As the beam joints expand due to moisture or shrink due to the angled stud joint, the upper bevel tapering plane 5 and the tapering tapering plane 6 move relative to the lower tapering tapering plane 5 and the tapering tapering plane 6.

According to the present invention, the angular stitch sealing edge 1 is firmly pressed relative to the stitch sidewall 2 when the two logs are joined perpendicularly. After joining, the copying surface 3 is pushed firmly into the surface to be measured. The sloping plane 5 of the neck studs is inserted into the sloping plane 6 of the stud neck. The sealing gap 11 remains at the bottom of the stud; it acts as a stabilization reserve.

The stud neck 8 must be filled with sealing material when the logs are joined as a wall in the house. The side wall 9 of the stud will be clearly visible on the outside of the joint. The spider sidewall 2 will be visible on the outside of the joint, extending identically to the spider sidewall 9. Thanks to the angled joint, the spider sidewalls 2 and 9 have a similar appearance to the joint known as the Norwegian stud.

The stability of the angular joint ratio is a consequence that the joint density will not change. When the dimensions change, the following displacements occur: the sealing edge 1 moves towards the stud side wall 2, the copying surface 3 moves towards the measuring surface 4, the sloping plane 5 moves towards the sloping plane of the stud side wall 6. The settling clearance above the sealing gap 11 will either decrease or increase.

The angular stud joint of the present invention keeps the log houses airtight with respect to climatic conditions. The joint also allows for the installation of houses made of partially dried logs, as the angled studs of the crossed logs remain firmly pressed together regardless of moisture content
