BACKGROUND OF THE INVENTION
The present invention relates to a wood shaft connector.
[0002]
[Prior art]
Conventionally, various timbers are used for wooden axes such as foundations, pillars, and beams of houses, and various sizes are prepared. For this reason, trees of a size suitable for them are required, and their resources are limited. Of the wooden shafts, the size of the beams in particular varies depending on the skip width, and there is a problem with spans of 3640 mm or more. These shaft assemblies are performed using expensive equipment that has been cut in advance, and the construction method is complicated and requires a lot of labor. Moreover, the heat insulation measure with respect to the shape of a complicated shaft assembly part is complicated.
[0003]
[Problems to be solved by the invention]
In the present invention, it is desired to reduce the number of types and save labor by using as simple a shaft set as possible without using a complicated shaft set and the expensive equipment required for this. In addition, we want to make a large cross-section and connection reinforcement easy and take a span of 3640 mm or more. Accordingly, the present invention is intended to provide a wood-axis joint that enables these.
[0004]
[Means for Solving the Problems]
Here, the inventor firstly cuts an isosceles triangular prism with a predetermined vertical width from three corners of a set of intersecting side faces of a wooden shaft that has a square cross section and stands upright, and this side face is the same. It consists of a covering part that covers the part cut by a predetermined depth in the vertical direction, an orthogonal part that extends the lower end of the covering part in the perpendicular direction, and an upright part that stands upright to the orthogonal part. The present inventors have found a wood shaft joint made of a metal plate that joins a wood shaft perpendicular to an upright wood shaft, which has a bolt hole.
[0005]
Secondly, a U-shaped covering portion covering a portion obtained by cutting the both sides and the upper surface of the wooden shaft at a horizontal position and having a square cross section with a predetermined width and a predetermined depth, and an upright surface of the covering portion It consists of an orthogonal part that extends in a perpendicular direction from the lower end, and an upright part that stands upright on the orthogonal part, and both upright surfaces of the covering part have protrusions protruding in the extension direction, and the protruding part has a perforated protruding piece And a tree orthogonal to each other in a horizontal position, comprising a combination of an upright portion and a projecting portion having bolt holes and an L-shaped piece having bolt holes on both orthogonal pieces standing on both ends of the orthogonal portion. We found a wood-axis joint made of metal plates that join the shaft.
[0006]
Thirdly, with respect to the C-shaped steel with the opening side up, the C-shaped steel is formed such that two perpendicular upright pieces of the same height as the top surface intersect at the center of the C-shaped steel. The center of the top of one upright piece is extended by a predetermined width and a predetermined length, each has a bolt hole, and a perforated protruding piece is joined to the top corner of the C-shaped steel Thus, the present inventors have found a wood shaft joint made of a C-shaped steel and a metal plate that joins a base wood shaft and an upright wood shaft.
[0007]

Use the parts that have already been adjusted. In addition, when joining three wooden axes that are orthogonal to each other in a T-shape when viewed from above, a pair of orthogonal parts and upright parts may be omitted from the second joining tool. When joining two wooden shafts that are orthogonal to each other while facing an upright wooden shaft, use two joints in which one pair of the orthogonal portion and the upright portion is omitted from one joint. The covering portions that do not have the bolt holes that are in contact with the diagonal portions and that have been adjusted for the corner interval are used in an overlapping manner. When one orthogonal wooden shaft is joined to the upright wooden shaft, a pair of the orthogonal portion and the upright portion may be omitted from one connector.
