Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column fixing device for a wooden building.

[0002]

2. Description of the Related Art A base is fixed by using anchor bolts projecting from a foundation concrete, and a tenon is fitted into a tenon provided on the base to stand on the base.

[0003]

In the conventional example, since the pillar is mounted on the base only by so-called tenon connection, the mounting strength is low. For example, only a reinforcing device such as a bracing device is required. In addition, the work of joining the tenon and tenon is complicated.

The present invention has been made in view of such a drawback of the conventional example, and has been devised to provide a fixing device having an unprecedented novel structure.

[0005]

SUMMARY OF THE INVENTION A joint fitting comprising a pillar erected on a pillar receiving plate placed on a foundation concrete, and a joining rod protruding from a substrate in an engaging hole vertically provided in the pillar. The connecting rod is inserted through the column receiving plate, and the connecting rod and the column are fixed to each other with a fixed rod, while a pressing piece is provided at a proper position of a pair of receiving rods protruding on both sides of the column receiving plate. Both ends are placed, and a first tightening nut is screwed into an anchor bolt that is erected on the foundation concrete and penetrated the holding piece to fasten the holding piece to the foundation concrete. The basic means is to penetrate a base placed on the foundation concrete via the receiving rod or the holding piece, and screw a second tightening nut to a tip of a bolt protruding from the base.

[0006]

1 is a longitudinal sectional view, FIG. 2 is a plan view showing a column without a pillar, and FIG. 3 is a perspective view of a bracket. It is.

In the figure, A is a fixing bracket, and a pair of fixing brackets A are provided on each of three sides of a square (substantially coincident with the end face of the pillar P) pillar-shaped receiving plate 2 having an engaging hole 1 at the center. Are formed by projecting receiving rods 3 and 3 having a square cross section of
In addition, the connecting rod 4 of the connecting bracket B is penetrated from the lower side of the column receiving plate 2 and is combined with the connecting member B to form the column receiving plate 2 and the receiving rods 3 protruding from three sides of the column receiving plate 2. 3 are placed on the foundation concrete Bc.

[0008] The joining bracket B is constructed by erection of the joining rod 4 on a substrate 5 superposed on the pillar receiving board 2 below the pillar receiving board 2. A through hole 7 provided in the connecting rod 4 by projecting from the column receiving plate 2 through the column receiving plate 2, being inserted into an engaging hole 6 provided vertically on the column P mounted on the column receiving plate 2, A fixed rod (a so-called drift pin is used in the embodiment, but a bolt and a nut may be used, and it may not be what is called a drift focus) in the through hole 8 provided in the column P so as to coincide with the through hole 7. 9) is inserted and fixed to the column P.

The base plate 5 of the joint fitting B interposed between the column receiving plate 2 and the foundation concrete Bc is provided with an extension 5A projecting from the column receiving plate 2 in the horizontal direction. Is interposed between a pair of receiving rods 33 arranged in a direction orthogonal to the other pair of two receiving rods 3, 3.3, 3.

The supporting rod 3 has a base end welded to the column receiving plate 2 to constitute the joint fitting B. The column receiving plate 2 is connected to the receiving plate 3 by the substrate 5 (or The board | substrate 5 (or extension piece 5A) interposition gap | interval 10 is located above the extension piece 5A) by the board thickness, ie, as shown in FIG. As shown, the column receiving plate 2 is supported by the receiving rod 3.

A notch 11 formed at the base of the extension piece 5A is for engaging a welding margin.

The pair of receiving rods 3 and 3 are placed on the foundation concrete Bc, and the pair of engaging rods 12
A and 12A are placed and combined, and the holding piece 12 matches the square shape of the receiving rod 3 with both ends of the central piece 12B provided with the elongated hole 13 in the width direction of the foundation concrete Bc (base b). An L-shaped engaging piece 12A is provided. An anchor bolt a protruding from a foundation concrete Bc is passed through the long hole 13 of the holding piece 12 so that the holding piece 12 is connected to the receiving rod. Place on 3 and 3 and combine, presser 1
The first tightening nut 15 is screwed into the anchor bolt a protruding by 2 and the pressing piece 12 is tightened and fixed to the foundation concrete Bc via the receiving rod 3.

The base concrete Bc provided on the holding piece 12
The anchor bolts a are made to penetrate through the elongated holes 13 long in the width direction in order to absorb an installation error of the anchor bolts a in the width direction of the foundation concrete Bc. The reason why the fixing bolt A is separated from the fixing bracket A) is to absorb an installation error of the anchor bolt a in the longitudinal direction of the foundation concrete Bc (in combination with an anchor bolt having a different installation position at the construction site from the beginning). Is also possible).

In the drawing, the base b is the anchor bolt a
A through hole 14 corresponding to the position is formed in advance, and the tip of an anchor bolt a protruding from the first tightening nut 15 is penetrated through the through hole 14 through the receiving rod 3 or the holding piece 12. Placed on the foundation concrete Bc,
A second tightening nut 16 is screwed to the tip of the bolt protruding from the through hole 14 and fixed to the foundation concrete Bc.

In addition, between the base b and the base concrete Bc other than the fixing bracket A (the receiving rod 2), for example,
The ventilation port material 17 as disclosed in Japanese Patent No. 24248 is scattered, and an interval generated between the base b and the foundation concrete Bc between the ventilation ports 17 functions as an underfloor ventilation port.

The ventilation opening member 17 has a plate thickness equal to that of the column receiving plate 1.
Therefore, the lower surface of the base b and the upper surface of the column receiving plate 2 are arranged so as to be on the same plane with each other, and the lower edge of the base b and the lower edge of the column P coincide with each other. The base b is fixed on the foundation concrete Bc.

In the embodiment, the bases b, b, b are arranged on three sides with the pillar P interposed therebetween. However, even if the bases are arranged on four sides or two sides, the present invention can be applied. Implementation is possible.

[0018]

The present invention has the configuration described above,
Compared with conventional tenon joints, the pillars can be firmly fixed,
In addition, since it adopts a configuration in which it is fixed not only to the base but also to the foundation concrete, the standing state can be reliably maintained, and a column fixing device having a novel structure can be provided.

According to the second aspect of the present invention, during the joining operation, the rotation of the joining metal fitting is prevented, so that the positional deviation between the through hole and the through hole provided as in the embodiment does not occur, and the fixed rod does not move. Can be performed smoothly.
