Abstract

PURPOSE:To correspond to the error of the implantation of an anchor bolt sufficiently by adjusting an adjusting member bored in a slot while the adjusting member is inserted rotatably into a hole, which is implanted to foundation concrete and into which the anchor bolt is inserted, and the slot is located at the position of the anchor bolt in a base plate. CONSTITUTION:A column 1 is disposed in upright into a frame body 2a welded on a base plate 2. The base plate 2 is placed on spread mortar 6 on foundation concrete 4. A plurality of holes 3 are formed to the base plate 2 at that time, and the diameters of the holes 3 are determined so as to be made larger than those of anchor bolts 5. Slots 3, into which the anchor bolts 5 are inserted, are bored to adjusting bolts 10, and the adjusting bolts 10 are rotated and the slots 13 are adjusted so as to be located at the positions of the anchor bolts 5. Nuts 7 are screwed and put into the anchor bolts 5, and the base plate 2 is fixed. Accordingly, the error of the implantation of the anchor bolts 5 is absorbed effectively, and the base plate 2 can be fixed firmly onto foundation concrete 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column pedestal, and more particularly,
The present invention relates to an anchor bolt capable of absorbing variations in planting position.

[0002]

2. Description of the Related Art Conventionally, this type of pedestal metal member is constructed by welding a metal base plate having a hole into which an anchor bolt is inserted at the lower end of a column.

The hole is formed to have a diameter sufficiently larger than the diameter of the anchor bolt so as to absorb the implantation error of the anchor bolt.

[0004]

However, in the above-described conventional column pedestal, a hole having a diameter sufficiently larger than the diameter of the anchor bolt is provided so that even if there is some error in the planting position of the anchor bolt, Although the bolts are configured so that they can be inserted, it was difficult to position the anchor bolts with high precision because the anchor bolts were planted in the foundation concrete.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and an object thereof is to provide a column pedestal member which can sufficiently cope with a large anchoring bolt installation error. .

[0006]

In order to achieve the above-mentioned object, a column pedestal according to the present invention has a base plate provided at the lower end of the column, and an anchor bolt of a base concrete planted in the base plate. A column base metal article having a hole to be inserted is characterized in that the hole is provided with an adjusting member which is rotatably inserted and which has an elongated hole into which the anchor bolt can be inserted.

[0007]

In the above structure, the adjusting member is rotated to adjust the elongated hole to the anchor bolt position, and the anchor bolt is inserted into the elongated hole.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a column pedestal according to an embodiment, in which a base plate 2 is fixed to a lower end of a column 1 made of a wooden column by welding. In addition, the pillar 1 is configured such that a lower end portion is inserted into a frame body 2a welded onto the base plate 2 and is erected, and the base plate 2 is set by an anchor bolt described later. Then, it is attached by welding.

The base plate 2 is provided with a plurality of holes (two in the illustrated example). The diameter of the hole 3 is determined to be sufficiently larger than the diameter of the anchor bolt 5 in which the lower portion is embedded in the basic concrete 4 and the upper portion is provided so as to project. That is, the diameter of the hole is determined to be larger than the diameter of the conventional hole in consideration of the planting error of the anchor bolt 5.

The base plate 2 is placed above the foundation concrete 4 with a mortar 6, so-called manju intervening, and is attached by screwing a nut 7 onto the anchor bolt 5. Is fixed by interposing the adjusting member 10.

As shown in the perspective view of FIG. 2, the adjusting member 10 has a collar portion 11 having a diameter larger than the diameter of the hole 3 in the upper portion.
And has an insertion portion 12 which is integrally formed with the collar portion 11 and has a diameter slightly smaller than the diameter of the hole 3 and a thickness smaller than the depth of the hole 3. The adjusting member 10 has a long hole 13 into which the anchor bolt 5 can be inserted.

Therefore, the adjusting member 10 is capable of rotating the circle of the hole 3, and the rotation causes the elongated hole 3 to rotate.
It becomes possible to insert the anchor bolt 5 located in a circle having the long axis as the diameter.

Therefore, even if there is an error in the installation of the anchor bolt 5, the base plate 2 can be firmly fixed to the foundation concrete 4 by tightening the nut 7 through the adjusting member 10.

FIGS. 3 and 4 are longitudinal sectional views of a column base metal article according to another embodiment of the present invention, which can be adopted when the base plate is thick.

That is, a step portion 2'matching the flange portion 21 of the adjusting member 20 is provided above the hole 3 of the base plate 2 so that the upper surface of the adjusting member 20 and the upper surface of the base plate 2 are aligned with each other. ing. It should be noted that the one-digit numbers of the reference numerals of the other components of the adjusting member 20 are the same as the numbers in the first embodiment, so further explanation is omitted.

In the above-mentioned embodiment, the pillar 1 is a wooden pillar, but it may be a steel pillar.

[0017]

The column pedestal according to the present invention has a base plate provided at the lower end of the column, and the column pedestal has holes for inserting anchor bolts planted in foundation concrete in the base plate. The hole is provided with an adjusting member that is inserted rotatably and has an elongated hole into which the anchor bolt can be inserted. Can be firmly fixed to.
