Abstract

PROBLEM TO BE SOLVED: To provide the efficiency of a work for fixing an anchor bolt to a foundation by fitting a nut screwed to the anchor bolt to a cap part provided in a base, placing it on a form, and pouring concentrate thereto. SOLUTION: A base plate 20A made of synthetic resin or hard rubber has caps 21 formed according to the setting position of anchor bolts 6a, 6b, and diameter parts for receiving the end parts of the anchor bolts 6a, 6b, which are fittable to nuts 5a, 5b, are formed on the inside of the caps 21, respectively. A pair of framework 2 constructing a foundation are erected, and face plates 3 are for mounted in the inside thereof. The base plate 20A, in which the caps 21 are installed to the nuts 5a, 5b screwed to the anchor bolts 6a, 6b is put on the face plates 3 and fixed thereto. Concrete 10a is poured into the framework 2, and the surface is finally finished by a finish iron while finish concrete 10b is poured in the lower part of the base plate 20A. Thus, the labor for setting an anchor bolt is saved, and the anchor bolt can be vertically fixed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate used to fix anchor bolts of a support in advance when the support is erected on a concrete foundation.

[0002]

2. Description of the Related Art Referring to FIG. 4, a description will be given of a case where columns are fixedly erected on a concrete foundation via base plates at appropriate intervals. FIG. 4 (A) shows a cross section of the concrete foundation when the concrete foundation is made. In the Kunkleit foundation 1, a pair of form bodies 2 are erected and the form bodies of the foundation 1 are formed in an inclined shape. Attach faceplate 3 inside 2. Then, in a state where the anchor bolts 6a and 6b are suspended from the substrate 4 via the pair of nuts 5a and 5b,
The substrate 4 is mounted on the faceplate 3 and fixed. In this state, the concrete 10a is poured into the form body 2 so as to leave a gap in the lower part of the substrate 4 where a finishing iron can enter. Then, while the finishing concrete 10b is placed under the substrate 4, the surface is finished with the finishing iron. Finish.

[0003] Thereafter, the concrete 10a, 10b
After the is solidified, remove the formwork 2 and face wood 3
When the nuts 5a and 5b are loosened and the substrate 4 is removed, the anchor bolts 6a and 6b are fixed to the foundation 1. When the support column 8 is to be erected, the base plate 7 is inserted into the anchor bolts 6a, 6b, and the nuts 5a, 5b are inserted.
b, and the columns 8 are mounted on the concrete foundation 1 at predetermined intervals (FIGS. 4B and 4C).

[0004]

In the above-mentioned construction process, when the surface of the finishing iron 10b is placed on the anchor bolts 6a and 6b while finishing the surface with the finishing iron while putting the finishing concrete 10b under the substrate 4, the anchor bolt 6
Since a and 6b are simply suspended, they may be inclined. Then, leave it as it is, concrete 10a,
When 10b is hardened, the anchor bolts 6a and 6b remain in an inclined state, and when attaching the base plate 7,
Fixing the anchor bolts 6a, 6b vertically may be troublesome, and the anchor bolts 6a, 6b
May crush the screw. Then, this invention provides the board | substrate for anchor bolts which solves the said subject.

[0005]

According to a first aspect of the present invention, there is provided a substrate in which a cap is provided corresponding to a mounting position of an anchor bolt, so that the anchor bolt can be easily attached to the substrate and the anchor bolt is inclined. Can be prevented.
The substrate of claim 2 facilitates the work of the finishing concrete by forming the notch. Further, in the substrate according to the third aspect, since the cap is connected and formed via the thin portion, the appearance can be improved by covering the cap with the nut.

[0006]

FIG. 1A is an overall view of a substrate 20A, and FIG. 1B is a cross-sectional view along AA. The substrate 20A is
It corresponds to the conventional substrate 4 and is made of synthetic resin, hard rubber, or the like, and has caps 21 corresponding to the installation positions of the anchor bolts 6a and 6b. This cap 21 is shown in FIG.
As shown in (B), the anchor bolt 6
a, a diameter portion 22b into which the distal end portions of the anchor bolts 6a, 6b can be inserted;
When a and 6b are mounted on the cap 21, the anchor bolts 6a and 6b are fixed to the substrate 20A by the elastic action of the material of the cap 21 (synthetic resin, rubber).

Incidentally, a cap 21 formed on the substrate 20A is provided.
The nuts 5a and 5b are screwed into anchor bolts 6a and 6
b is formed on the premise that the diameter of the anchor bolt 6 is not screwed with the nuts 5a and 5b.
a and 6b corresponding to the diameter portion 22b of the anchor bolt 6
a, 6b so as to be able to be fitted to the tip of the
a may be eliminated and formed only by the diameter portion 22b. That is, the cap 21 may be formed so as to be fittable at the distal ends of the anchor bolts 6a, 6b or via the nuts 5a, 5b so that the cap 21 can be fixed by the elastic action of the cap 21.

Next, an operation of fixing an anchor bolt to the concrete foundation 1 and erecting a fixed post 8 to the base plate 7 using the substrate 20A will be described with reference to FIG. First, in the same manner as in the prior art, a pair of formwork bodies 2 are erected, and a face tree 3 is attached inside the formwork bodies 2 in order to form the corners of the foundation in an inclined shape. And nuts 5a, 5 screwed into the anchor bolts 6a, 6b
In FIG. 2B, the substrate 20A mounted on the cap 21 is placed on the faceplate 3 and fixed (FIG. 2A). In this state, the substrate 20A
Formwork body 2 just enough to leave a gap at the bottom of
Concrete 10a is poured into the inside, and then the surface is finished with a finishing iron (not shown) while the finishing concrete 10b is placed under the substrate 20A.

Even if the finishing iron hits the anchor bolts 6a, 6b during the above operation, the anchor bolts 6a, 6b are fitted to the cap 21, so that the anchor bolts 6a, 6b hardly incline and maintain a vertical state. ,
Even if 10b is hardened, anchor bolts 6a and 6b are fixed in a vertical state. Next, concrete 10a, 10b
After the hardening, the substrate 20A is removed and the nut 5 is removed.
a, 5b are removed, the base plate 7 is inserted into the anchor bolts 6a, 6b, and fixed with the nuts 5a, 5b. As described above, the anchor bolts 6a, 6b
Can be fixed in a so-called one-touch manner by being inserted into a cap 21 formed on the substrate 20A, and the anchor bolts 6a and 6b can be fixed to the substrate 4 via nuts 5a and 5b as in the related art.
You can save time and effort compared to setting
Since it is mounted on the base 1, it is fixed to the foundation 1 with almost no inclination.

FIG. 3 shows another substrate 20B to be used in the same manner as the substrate 20A, and FIG.
3 (B) is a plan view, FIG. 3 (C) is a view of a concrete foundation being prepared (corresponding to FIG. 2 (A) showing a cross section), and FIG. 3 (D) is a finish view with columns upright. The substrate 20B is made of the same material as the substrate 20A, has a notch 25 formed around the periphery of the cap 21, and the cap 21 is connected and formed via a thin portion 26. This thin part 26
Refers to a state in which the cap 21 can be connected to the substrate 20B, is in the original state even when the anchor bolts 6a, 6b are applied with a finishing iron, and can be easily cut with scissors or the like.

When this substrate 20B is used, FIG.
As shown in (2), when the surface is finished with the finishing concrete 10b, the notch 25 allows the finishing iron to work from the upper portion of the board 20B to almost near the center of the board 20B, thereby improving work efficiency. Can be.

Since the cap 21 is formed on the substrate 20B via the thin portion 26, the cap 21 is cut off with scissors or the like after the substrate 20B is removed.
Then, after fixing the support post 8 to the anchor bolts 6a, 6b via the base plate 7 with the nuts 5a, 5b, the cap 21 is fitted into the nuts 5a, 5b to improve the aesthetic appearance. Can be effectively used.

[0013]

According to the first aspect of the present invention, a substrate for an anchor bolt is
Since the anchor bolt can be set via the cap, work efficiency can be improved. Further, since the notch is formed in the substrate according to the second aspect, the finishing operation at the center of the substrate becomes easy. In the substrate according to the third aspect, since the cap can be easily separated from the substrate, the appearance can be improved by covering the cap with the nut.
