DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a building having an architectural structure such as a wooden framed house, and more particularly, to a technique for building a pillar.

[0002]

2. Description of the Related Art In a frame structure, a frame is formed by assembling various members such as a base, a pulling bar, a pillar, etc. on a foundation, and the connection of the various members as described above is performed by a joint or a joint. I was However, in order to use joints and connections, processing with high dimensional accuracy as designed is indispensable, and the burden on work is large. Therefore, in recent years, the processing of the connection has been simplified by interposing a metal joint between the members, and the load required for the processing has been reduced.

In recent years, instead of forming a square ventilation hole as a base as in the past, a spacer called a base packing, a cat mortar, a cat base, etc. is intermittently arranged between the base and the base. Then, a ventilation path for underfloor ventilation is formed.

However, since this type of structure is an important part for supporting a load, the use of a metal joint as described above has not been performed when erecting a pillar. Still, it was necessary to use a connection that required precise processing, and it was not possible to fully enjoy the advantages such as shortening the construction period.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is a main object of the present invention to sufficiently obtain advantages such as shortening of a construction period even in a structure in which ventilation is performed under the floor by interposing a spacer.

Means for this is to fix a joint metal having a plate-shaped base plate and an upright portion erected on the upper surface of the base plate on a base, and to mount the joint metal on the base plate of the joint metal. And a lower end of the pillar is inserted into the upright portion to build the pillar.

That is, the joint metal is fixed on the foundation by using an anchor bolt projecting upward from the foundation, or by embedding a base plate in the upper surface of the foundation, and the base is also fixed to the joint metal. Fix it on the base plate. Then, the column material is inserted into the upright portion of the metal joint to be built. The base may be mounted and fixed by abutting the end faces so as to sandwich the upright portion of the metal joint, or may be mounted and fixed by abutting the side surface of the pillar so as to sandwich the pillar.

In this structure, the end face of the base may be processed by a vertical cut surface if the upright portion is a flat plate, and a corresponding shape if the upright portion is, for example, a column or a prism. What is necessary is just to form in the shape which has a notch part, and is simple. Also, the end face of the column material may be formed by forming a horizontal cut surface and then forming a notch portion into which a standing portion of the joint metal is inserted, which is extremely simple. Moreover, the joining hardware is firmly fixed with the base plate interposed between the foundation and the base,
Since the erected portion supporting the column material is erected on the base plate, sufficient strength to support the load can be obtained.

Another means is to form a base plate to be interposed between a foundation and a base, and to form an upright portion to be inserted from below from a top surface of the base plate into a pillar to be built. It is characterized by being hardware.

In this case, it is preferable that the thickness of the base plate is set to be the same as the thickness of the spacer interposed between the base and the base to secure the ventilation path. By interposing the base plate between the foundation and the base, the necessary processing of the base can be eliminated, and the processing can be further simplified. This is because it is easy to respond to

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a column base of a wooden frame structure, and shows a column base in a case where a ventilation passage 4 for underfloor ventilation is formed by interposing a spacer 3 between a foundation 1 and a base 2. Is shown. The column base is constructed by building a column 6 using a metal joint 5 interposed between the foundation 1 and the base 2.

The right side of FIG. 1 shows an intermediate column base, and the left side shows an outgoing column base. Since the basic configuration is the same, the right intermediate column base will be described below as an example. .

First, a metal joint 5 forming an intermediate column base portion
2 includes a base plate 7 and a standing portion 8 erected from the upper surface of the base plate 7 as shown in FIG. 2, and is fixed on the foundation 1 to support the lower end of the column member 6. Base plate 7 is foundation 1
It is formed in a rectangular plate shape so as to ride on it, and a rectangular plate-shaped standing portion 8 is erected at an intermediate portion in the length direction. Standing part 8
Is set to be larger than the thickness of the base 2 so as to protrude above the base 2.

The thickness of the base plate 7 is set to be the same as the thickness of the spacer 3. In order to fix the base 1 and the base plate 7, and the base plate 7 and the base 2, an anchor bolt 9 protruding upward from the base 1 and a hexagonal bolt 10 for fixing the base 2 are inserted through the base plate 7 from below. Two insertion holes 7a are formed side by side in the longitudinal direction with the standing portion 8 interposed therebetween. Under the insertion hole 7a, there is formed a detent housing part 7b having a shape and a dimension capable of holding the head of the hexagon bolt 10 within the thickness of the base plate 7 and preventing detent (see FIG. 3).

The number of the insertion holes 7a may be one, and as shown in FIG.
The work is easier if the hex bolt 10 is inserted. This is because it is difficult for the anchor bolt 9 to be erected at an accurate position that has been scheduled in advance.

An insertion hole 8a is also formed in the upper part of the upright portion 8 so that a hexagon bolt 11 for fixing the column member 6 can be inserted therethrough. Note that a drift pin may be used instead of the hexagon bolt 11.

The two bases 2 have a vertical cross-section so as to be in surface contact with the upright portion 8, and have through holes vertically penetrating at positions corresponding to the insertion holes 7 a of the base plate 7. 2a is formed. At the upper end of the through hole 2a,
A large-diameter concave portion 2b is formed so that the nut 12 to be screwed can be accommodated.

The column member 6 has a horizontal cut surface so as to be in surface contact with the upper surface of the base 2, and has a vertical cut groove 6 a formed so as to allow insertion of the upright portion 8 of the joint metal member 5. are doing. Further, a through hole through which a hexagon bolt is inserted is formed at a position corresponding to the insertion hole of the standing portion. At both ends of the through hole 6a, a concave portion 6c for accommodating the head of the hexagon bolt 11 and the nut 12 is formed.

The metal joint 5 thus constructed and the base 2
The column member 6 is assembled as follows. First, the joining hardware 5 is arranged on the foundation 1 in the same manner as the arrangement of the spacer 3 on the foundation 1. At this time, the anchor bolts 9 are inserted into the two insertion holes 7a formed in the base plate 7, but in the illustrated example, the anchor bolts 9 are inserted into the outer insertion holes 7a and the inner insertion holes 7a are inserted. A hexagon bolt 10 is inserted through the hole 7a. Conversely, both may be anchor bolts 9 or hexagon bolts 10.

Thereafter, the base 2 is connected to the joining metal 5
Is placed on the base plate 7 in a state of surface contact with the standing portion 8 of
A nut 12 is screwed into a tip of the anchor bolt 9 and the hexagonal bolt 10 inserted into the through hole 2a of the base 2, and tightened.

Subsequently, the cut groove 6a of the column member 6 is inserted into the upright portion 8 of the metal joint 5, and in this state, the hexagon bolt 10 is inserted into the through hole 6b, and the nut 12 is tightened. The state where the material 6 is set up is maintained.

As shown in FIG. 4, the lower end surface of the column member 6 may be brought into contact with the base plate 7 of the metal joint 5, and the column member 6 may be assembled so as to be sandwiched between the two bases 2.

In this way, assembly can be performed very easily. Moreover, the processing of the end faces of the base 2 and the pillars 6 is also easy. Therefore, simplification of the work and shortening of the construction period can be realized.

The metal joint 5 is fixed with the base plate 7 interposed between the foundation 1 and the base 2, and the erected portion 8 for supporting the column 6 is erected on the base plate 7. As a result, sufficient strength to support the load can be obtained.

Further, since the thickness of the base plate 7 of the metal joint 5 is set to be the same as that of the spacer 3, the same effect as the arrangement of the spacer 3 is produced only by fixing the metal joint 5 on the base 1. The operation is extremely simple without any trouble such as using another spacer on top of another.

The metal fittings 5 used for the column bases at the protruding corners shown in FIG. 1 are formed so that the standing position of the standing portion 8 with respect to the base plate 7 is shifted to one side in the length direction. The erected position is set at half the width of the base 2 from the end, and one base 2
Upright portion 8 in a cut groove 2c formed along the length direction
Is configured to enter. This metal joint 5 can also be used in the corner. In addition, as shown in FIG. 5, the base plate 7 may be formed in an L shape in plan view.

FIG. 6 shows the metal joint 5 when the base 2 is arranged on all sides, and FIG. 6 shows the metal joint 5 when the base 2 is arranged on three sides. On a base plate 7 of a required shape having a portion on which the base 2 rides,
It is constructed by standing up. The standing portion 8 may be formed in a three-dimensional shape such as a column shape or a polyhedral shape in addition to the plate shape as described above.

[0028]

In other words, according to the above-described structure, it is possible to simplify the joint processing of the base and the column material, and it is possible to simplify the work and shorten the construction period. In addition, since the metal joints with the erected parts are used on the base plate that is fixed between the base and the base, sufficient strength to support the load can be achieved even with the simple processing as described above. can get.

Further, since the joint hardware is composed of a base plate and an upright portion, it is most suitable for a structure in which ventilation under the floor is performed by interposing spacers which have recently increased. In particular, if the thickness of the base plate is set as in claim 3, the same effect as the arrangement of the spacers can be obtained only by fixing the joining hardware on the base, and another spacer can be used by overlapping. The work is simple and effortless.
