Description

  The present invention relates to a connection structure between a foundation and a pillar for the purpose of strongly connecting a concrete foundation and a pillar in a wooden structure, and in particular, enhancing the pulling force of the pillar, and a connection hardware used for this connection structure. About.

  Conventionally, in a wooden structure, a base is fixed to the upper surface of the foundation, and a pillar is erected on the base. In this case, in order to integrally form the foundation, the foundation, and the pillar, for example, in order to connect the foundation and the foundation, the upper end of the anchor bolt embedded in the foundation is inserted into the vertical hole of the foundation, and the upper end of the anchor bolt is inserted. Various nuts were screwed to the part and fixed to the upper surface of the base. In order to connect the foundation and the pillar, an attracting hardware (hole-down hardware) is fixed to the side of the pillar, and a nut is screwed into the upper end of the anchor bolt that penetrates the vertical hole of the base to engage the attracting hardware. It was fixed.

  In this case, the “base and foundation” and “foundation and column” are joined, but the three members are not joined, and separate anchor bolts for the base and foundation are required, increasing the number of anchor bolts. In order to solve this problem, the top end of the anchor bolt is fixed to the base with a flanged nut (slipped nut with seat), and the tip of the bolt that locks and fixes the head to the metal fitting is screwed and tightened to the flanged nut Has been proposed (Patent Documents 2 and 3). In addition, in order to fix the brace fixing hardware to the base, the upper end of the anchor bolt is fixed with a long nut on the upper surface of the brace fixing hardware, and the lower end of the bolt that is pulled to the long nut and locked to the hardware is fixed. A structure for screwing and tightening has also been proposed (Patent Document 1).

In addition, it is desirable that the anchor bolt shaft and the attachment shaft of the attracting metal are coincident with each other. However, in consideration of the case where this is shifted, the upper end of the anchor bolt and the bolt with the head fixed to the attracting metal are fixed. The structure which connects a lower end part via the connection adjustment nut (eccentric adjustment metal fitting) which has an eccentric screw hole is proposed (patent documents 4 and 5).

  In the conventional technology, the bond between the foundation, the base, and the column is strengthened, but the pulling force of the column itself cannot be increased. In order to increase the pulling force that must be borne by a single column, up to the material strength of the column itself, the material strength of the anchor bolts and attracting metal must be increased, or the number of anchor bolts and attracting metal connected to the column must be increased. It was good. In this case, at the corners of the bases 22 and 22, two adjacent side surfaces of the pillar 36 (FIG. 4B), and at an intermediate part of the base 22 on two opposite side surfaces of the column 36 (FIG. 4A), A structure in which the attracting metal object 42 is fixed and the corresponding anchor bolt 25 is embedded, or a structure in which two attracting metal objects 42 and 42 are arranged on one side surface of the column 36 has been considered (FIG. 4C).

  However, in these methods, the attracting metal 42 is fixed at the same height of the pillar 36, so the number of bolts and screw bolts for fixing the pillar 36 and the attracting metal 42 is concentrated, and the cross section of the pillar 36 is concentrated. There is a problem that the defect becomes large and the strength of the pillar 36 against bending or the like is reduced. In the third structure, since the anchor bolts 25 and 25 are arranged in parallel in the width direction of the foundation, there is a problem that it is difficult to secure the concrete cover thickness of the anchor bolts 25 and 25.

  However, the present invention uses a connection hardware in which the first connection part having the first insertion hole and the second connection part having the second third insertion hole are vertically aligned on the side surface of the column with the axis aligned. Alternatively, since the connecting hardware fixing the first connecting portion having the first insertion hole and the connecting hardware fixing the second connecting portion having the second third insertion hole are arranged in a line with the axis aligned, the above-mentioned problem Solved.

In other words, the present invention is a structure in which a pillar is erected on a foundation via a base or directly, and has the following requirements.
(1) The first connecting hardware and the second connecting hardware are fixed in series on the side surface of the column from above, and the first connecting hardware includes a first connecting portion having a first insertion hole, The connecting hardware has a second connecting portion having a second insertion hole and a third insertion hole. The first insertion hole and the second insertion hole are arranged coaxially with an axis parallel to the axis of the column.

(3) The upper end portion of the second anchor bolt is coupled to the second coupling portion of the second coupling hardware.

In addition, another invention is a structure in which a pillar is erected on a foundation via a base or directly, and the foundation and the pillar are characterized by having the following requirements. .
(1) A coupling hardware is fixed to the side surface of the column, and the coupling hardware includes a first coupling portion and a second coupling portion in order from above, and the first coupling portion has a first insertion hole, The second connecting portion has a second insertion hole and a third insertion hole that are coaxial with the first insertion hole. The second insertion hole and the third insertion hole are arranged substantially parallel to the side surface of the column, and the second insertion hole is positioned on the side closer to the column and the third insertion hole is positioned on the side farther from the column. .
(2) An anchor bolt embedded in the foundation, the first anchor bolt being the side closer to the side of the column, the second anchor bolt being the far side, and the upper end of the first anchor bolt passing through the second insertion part The part is coupled to the first coupling part directly or via a connection hardware.
(3) The upper end portion of the second anchor bolt is coupled to the second coupling portion of the coupling hardware.

Furthermore, another invention is a connected hardware characterized by satisfying the following conditions.
(1) A first connection part is formed on the upper part of the substrate that can be fixed to the side surface of the pillar, and a second connection part is formed on the lower part.
(2) The first connection part has a first insertion hole through which the upper end of an anchor bolt embedded in the foundation can be inserted, and the second connection part has a second insertion hole through which the anchor bolt can be inserted, and the like. And a third insertion hole through which the anchor bolt can be inserted. The first insertion hole and the second insertion hole are formed coaxially.
(3) The first connecting portion has a first locking edge capable of locking and fixing the anchor bolt or a connecting rod connected to the upper edge of the anchor bolt, and the second connecting portion is another anchor bolt. A second locking edge capable of locking and fixing the upper end of the second locking edge.

  The “linkage” in the above refers to connection so as to receive a load, and its structure such as screwing and locking is arbitrary.

  This invention uses, on the side surface of the column, a connecting hardware in which the first connecting portion having the first insertion hole and the second connecting portion having the second third insertion hole are vertically aligned with their axes aligned, Alternatively, since the connecting hardware that fixes the first connecting portion having the first insertion hole and the connecting hardware that fixes the second connecting portion having the second third insertion hole are arranged in a column with the axes aligned, one column It is possible to connect two anchor bolts to one side surface of the steel plate, thereby improving the connection between the concrete foundation and the column and enhancing the pulling force of the column. In addition, since the connecting hardware, anchor bolts, and the like are coaxially arranged in a line, there is room on the side of the column, which can effectively cope with a true wall structure in a Japanese-style room.

  Also, with respect to the side of one pillar, the number of connecting parts of the connecting hardware is increased, or the number of connecting hardware having connecting parts is increased vertically, thereby adjusting the number of anchor bolts to be used and pulling force There is an effect that can be easily adjusted.
