Abstract
A log house made of individual logs in which in order to form the corner joints each lower log has, in the area in which a log rests on it, slanting cuts parallel to its centre line which form a saddle. Each resting log has, in the area of the lower log, a V-notch which overlaps the saddle, resting with both of its lateral areas on the slanting cuts of the lower log. In order that the joint is substantially leakproof the saddle is divided, at least in the area of one saddle side, by means of a crosspiece, and the V-notch is divided, at least in the area of one V-notch flank, by means of a groove running in the longitudinal direction of the resting log, the crosspiece engaging in the groove where logs are resting on one another.

Claims (10)
1. A log house made of individual logs in which in order to form the corner joints each lower log has, in the area in which a log rests on it, slanting cuts paral-lel to its centre line which form a saddle and each resting log has, in the area of the lower log, a V-notch which overlaps the saddle, resting with both of its lateral areas on the slanting cuts of the lower log characterized by the fast that the saddle (5) is divided, at least in the area of one saddle side, by means of a crosspiece (4) and the V-notch (7) is divided, at least in the area of one V-notch flank (9), by means of a groove (11) running in the longi-tudinal direction of the resting log (2), the crosspiece (4) engaging in the groove (11) where logs (1, 2) are resting on one another.
2. A log house made of individual logs in accordance with Claim 1 characterized by the saddle (5) being divided in the area of both saddle sides by means of a cross-piece (4) and the V-notch (7) in the area of both V-notch flanks (8, 9) by means of the groove (11).
3. A log house made of individual logs in accordance with Claim 1 or 2 characterized by the fact the the exter-ior contour of the crosspiece (4) corresponds to that of the rough log (1) in this crosspiece area.
4. A log house made of individual logs in accordance with one of Claims 1 to 3 characterized by the fact that the resting log (2) and the lower log (1) are arranged at an angle of 90° in order to form the corner joint.
5. A log house made of individual logs in accordance with Claim 4 characterized by the fact that the crosspiece (4) divides the saddle (5) into two saddle halves arranged symmetrically to the crosspiece (4).
6. A log house made of individual logs in accordance with Claim 4 or 5 characterized by the fact that the groove (11) divides the V-notch (7) into two V-notch halves arranged symmetrically to the groove (11).
7. A log house made of individual logs in accordance with one of Claims 1 to 6 characterized by the fact that the resting log (2) has a longitudinal groove (10, 11) on its lower side, the longitudinal groove (11) serv-ing as the seat of the crosspiece (4) of the lower log (1) in the area of the V-notch (7).
8. A log house made of individual logs in accordance with one of Claims 1 to 7 characterized by the fact that at least one slanting cut (3) has a drainage trough (15) which runs at an acute angle to the crosspiece (4) from the corner (16) formed by the crosspiece related to the slanting cut (3) and the saddle comb (6) pro-duced between the slanting cuts (3) to the exterior of the logs (17).
9. A log house made of individual logs in accordance with one of Claims 1 to 8 characterized by the fact that the crosspiece (4) has a rectangular, trapezoidal, or triangular cross-section.
10. A log house made of individual logs in accordance with one of Claims 1 to 8 characterized by the fact that each crosspiece (4) is designed as a bevelled edge directed towards the exterior of the log house.
