Description

  The present invention relates to a column base bracket for a wooden structure and a method for reinforcing a wooden structure using the same.

  In general, the structure of a building such as a wooden house is composed of a base material that is laid along the foundation and a pillar material that is erected on the base material. .

  In recent years, such wooden houses have been required to have improved earthquake resistance and countermeasures for aging. In particular, the reinforcement of the joint between the base material and the pillar material, which is important for supporting the weight of the house, is regarded as important.

Conventionally, as a reinforcing member and a reinforcing method of a wooden structure, an L-shaped bracket and a reinforcing member arranged in a bracing manner with respect to the L-shaped bracket are fixed with screws (for example, Patent Document 1).
JP 2003-293463 A (Claims, FIGS. 1 to 4)

  However, the technique described in Patent Document 1 is to fix the reinforcing metal fitting directly to the base material and the column material with screws or the like. For this reason, there is a concern that it cannot be applied when the wood of the joint part to be reinforced is deteriorated due to the damage or corrosion caused by white ants.

  The present invention has been made in view of the above circumstances, and a column base metal fitting that can easily reinforce a joint portion even when the wood of the joint portion is deteriorated and a wooden structure using the same. It is an object to provide a reinforcing method.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a column base metal fitting that reinforces a joint portion between a wooden column material and a base material, and an fitting portion that covers a lower end portion of the column material, And a fitting portion fitted in a mortise provided in the base material.

  By comprising in this way, even if the lower end part of a pillar material deteriorates, a base material and a pillar material can be joined by excising the said part and coat | covering a fitting part.

  According to a second aspect of the present invention, in the column base metal fitting of the wooden structure according to the first aspect, the fitting portion and the fitting portion have a hollow extruded shape member having at least one rib along the longitudinal direction of the base material. The fitting portion is formed of the rib and the remaining U-shaped section obtained by cutting away the side piece parallel to the rib, and the fitting portion includes the rib and the rib. It is characterized by being formed of a hollow rectangular portion composed of side pieces parallel to the ribs or ribs parallel to each other and side pieces perpendicular to the ribs.

  By comprising in this way, since a column base metal fitting is integrally formed with a hollow extrusion shape material, while improving an intensity | strength, cost reduction can be achieved. Further, the dimensional accuracy can be improved by forming the tenon using the rib of the extruded shape member.

  This vertical structure of a wooden building is made up of a base material 2 installed on a foundation 1 of a wooden structure and a column material 3 installed on the base material 2 as shown in FIG. This is a structure in which the base material 2 and the column material 3 are connected using the metal fitting 4.

  The foundation 1 is made of concrete with reinforcing bars. An anchor bolt 5 is erected on the foundation 1 for removing the standing position of the pillar material 3 and fixing the base material 2.

  The base material 2 is provided with a mortise 6 that opens toward the upper end and outwards at the joint portion of the pillar material 3 on the side surface on the outer wall side of the wooden building (see FIG. 3). A fitting portion 41 of a column base metal fitting 4 to be described later is fitted into the mortise 6.

  The column member 3 is made of wood, and the deteriorated portion at the lower end thereof is cut out, and the fitting portion 42 of the column base metal fitting 4 described later is formed on three sides of the lower end portion of the column member 3 after being cut out. Is covered. When the column member 3 is joined to the base member 2, two fixing through-holes 31 that are parallel to each other are formed in two opposite sides of the lower end portion of the column member 3.

It is good also as a tenon with the both cylinders which consist of these side pieces 20b and 20c orthogonal to these 43 and 43a. Further, the mortise 6B of the new base material 20A may be formed between the two ribs 21a and 21b of the new base material 20A in accordance with the fitting portion 41A of the column base metal 4A.

  In this way, the fitting portion 41A of the column base metal 4A is used as a tenon with both barrels, and the mortise 6B of the new base material 20A is formed between the two ribs 21a and 21b of the new base material 20A, thereby The leg bracket 4 and the new base material 20 </ b> A can be positioned, fitted, and joined without any deviation.

  In FIG. 13, the other parts are the same as those in the third embodiment, so the same parts are denoted by the same reference numerals and description thereof is omitted.
