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 in a tenon hole provided on the base so as to be erected 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]

A column is erected on a column receiving plate placed on a foundation concrete, and the column and the connecting piece erected on the column receiving plate are overlapped in a horizontal direction and fixed with a fixed rod. Fastened to each other, in place of a pair of receiving rods protruding on both sides of the pillar receiving board,
A first tightening nut is screwed into an anchor bolt which is placed on both ends of the holding piece, erected on the foundation concrete and penetrated the holding piece, and tightens the holding piece on the foundation concrete. Through a base placed on the foundation concrete via the receiving rod or the pressing piece, and screwing a second tightening nut to a tip of a bolt protruding from the base as a basic means. By inserting the connecting piece into the slit provided in the pillar, the connecting piece is hardly visible from the outside and the appearance is improved, and the holding piece is separate from the receiving rod, and the holding piece is long in the width direction of the foundation concrete. By providing a long hole for anchor bolt penetration, an error in the installation of the anchor bolt is absorbed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of a partly cut-off apparatus for a wooden building according to the present invention, FIG. 1 is a partially cutaway front view, FIG. FIG. 4 is a perspective view of a metal fitting, and FIG. 5 is a perspective view of another embodiment of the metal fitting.

In the drawing, A is a fixing bracket, and the fixing bracket A is provided with a pair of receiving rods 2 and 2 projecting on opposite sides of a column receiving plate 1, and on the lower surface of the distal end portion of the receiving rods 2. A reinforcing piece 3 is fixedly attached by pulling, and a connecting piece 4 is erected at the center of the pillar receiving board 1 so as to have the same width as the pillar receiving board 1. 9 are arranged in the vertical direction, and engaging portions 6 at both ends of a holding piece 5 separate from the receiving rod 2 (fixing metal A) are provided at appropriate positions of the receiving rods 2 and 2 of the fixing metal A. , 6 are placed and combined, and the holding piece 5 is provided at both ends of a central piece 5A provided with an elongated hole 7 in the width direction of the base concrete Bc (base b) with the circular cross section of the receiving rod 2 at both ends. It is provided with the engaging portion pieces 6 and 6 on a matching circular curve. That is, in the column fixing device of the embodiment, the column P is fixed by using the fixing bracket A and the pressing piece 5 in combination.

[0008] The fixing bracket A is made of a foundation concrete Bc.
An anchor bolt a protruding from the upper surface of the base is placed at a predetermined position of the foundation concrete Bc so as to be interposed between the receiving rods 2 and 2, and the anchor bolt a is penetrated through the elongated hole 7. The engaging portion 6 of the holding piece 5 combined with the a
The first tightening nut 10 is attached to the protruding anchor bolt a.
And the holding piece 5 is fixed to the basic concrete Bc via the receiving rod 2 so as to be fastened to the basic concrete Bc.

The anchor bolt a is made to penetrate through the elongated hole 7 in the width direction provided in the base concrete Bc in the holding piece 5 in order to absorb the installation error of the anchor bolt a in the width direction of the base concrete Bc. The reason why the holding piece 5 is made separate from the receiving rod 2 (fixing bracket A) is to absorb an installation error of the anchor bolt a in the longitudinal direction of the foundation concrete Bc (from the beginning, construction work). This is also because it can be combined with anchor bolts with different installation positions at the site).

In the drawing, b is a base, and the base b has a through hole 11 formed in advance corresponding to the position of the anchor bolt a, and the tip of the anchor bolt a protruding from the first tightening nut 10 in the through hole 11. Is mounted on the foundation concrete Bc via the receiving rods 2 to the holding pieces 5, and a second tightening nut 12 is screwed and fastened to the tip of a bolt projecting from the through hole 11 to the foundation concrete Bc. It is fixed.

In addition, between the base b and the base concrete Bc other than the fixing bracket A (rod 2), for example,
The ventilation port material 13 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 13 functions as an underfloor ventilation port.

The ventilation opening 13 has a plate thickness equal to that of the column support 1.
Therefore, the lower surface of the base b and the upper surface of the column receiving plate 1 are arranged so as to be on the same plane with each other. The base b is fixed on the foundation concrete Bc so that the edges coincide with each other.

The column P is provided with a slit 14 at the center of the lower end face thereof, and a connecting piece 4 erected on the column receiving plate 1 fixed on the foundation concrete Bc is inserted into the slit 14 so as to be inserted therebetween. It is placed on the top (the width of the gap formed by the bases b, b and the width of the column receiving plate 1 and the column P are the same width), and a through hole 11 ′ formed in advance so as to match the through hole 9. A drift pin 8 (which may be replaced with a bolt and a nut) is inserted from one end of the column P, and the column P is erected on the foundation concrete Bc to obtain an embodiment apparatus.

FIG. 5 shows the first embodiment in which the bases b, b are arranged on two sides with the pillar P interposed therebetween, whereas the bases b, b are arranged on all sides. , B, and b are shown, and the remaining parts can be understood in the same manner as in the first embodiment, and therefore the description is omitted.

The connecting piece 4 (having the same width as the column P) in the embodiment is provided upright at the center of the column receiving plate 1. For example, it is provided at opposite ends of the column receiving plate 1 and provided at both ends. The column P may be interposed between the connecting pieces.

[0016]

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.
