Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for fixing a building base on a foundation.

[0002]

2. Description of the Related Art Conventionally, when fixing a foundation 16 of a building on a foundation 17, the lower portion of an L-shaped anchor bolt 18 is vertically embedded in a concrete foundation 17, as shown in FIG. The upper part was penetrated through the base 16, and the protruding portion on the upper surface of the base 16 was fixed with a washer 19 and a nut 20.

[0003] The concrete foundation 17 is formed by assembling a formwork and placing concrete in it, but in order to fix the base 16 horizontally on the foundation 17, before the concrete hardens. In addition, it was necessary to vertically embed the anchor bolt 18 and level the top end of the foundation 17 by leveling.

However, since the anchor bolt 18 is long and heavy, it easily tilts in uncured concrete and is difficult to mount vertically, and it takes a lot of manpower to level the top end of the foundation 17 horizontally. It takes time and the base 16
It was not easy to fix the horizontal on the foundation 17.

SUMMARY OF THE INVENTION Therefore, the present invention
An object of the present invention is to provide a fixing mechanism for a building base that enables a building base to be easily and horizontally fixed on a foundation.

[0006]

In order to solve the above-mentioned problems, the present invention employs the following technical means.

In the structure for fixing the base of a building according to the present invention, an anchor bolt having a lower portion fixed to a foundation and an upper portion supporting the foundation of the building is screwed to the sleeve embedded in the foundation. By doing so, the upper and lower positions are adjustably attached, and the upper and lower positions of the anchor bolts are appropriately adjusted so that the base can be horizontally fixed on the foundation.

A male screw is formed on the upper part of the anchor bolt,
By penetrating from the bottom surface of the base to the upper surface, a receiving portion that supports the bottom surface of the base is provided below the portion where the male screw is formed, and a nut is screwed into the portion penetrating the base and protruding to the upper surface of the base. The base may be clamped between the nut and the receiving portion to support it.

As a result of adopting the above means, the present invention has the following actions. Since the fixing mechanism of the foundation of the building of the present invention does not embed the anchor bolt in the foundation of uncured concrete but attaches it by screwing it into the sleeve embedded in the foundation, the anchor bolt does not tilt, and moreover, Since the vertical position of the anchor bolt can be adjusted by rotating it, even if the top end of the foundation is not leveled accurately, the anchor bolt can be easily adjusted to adjust the vertical position. Can be fixed horizontally.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
This will be described with reference to the drawings.

The building base fixing mechanism according to the present invention fixes a lower part 1 to a foundation 2 and an upper part 3 to a building base 4.
Anchor bolt 5 adapted to support the anchor bolt 5 is attached by screwing the lower portion 1 into a sleeve 6 embedded in a foundation 2 so that the vertical position can be adjusted.
The base 4 can be horizontally fixed on the foundation 2 by appropriately adjusting the vertical position of the base.

To carry out the present invention, first, when forming the concrete foundation 2, the sleeve 6 is embedded in the foundation 2. The foundation 2 is provided with reinforcing bars (not shown), and FIG.
It is formed by assembling the formwork 7, pouring concrete into it, and removing the formwork 7 after hardening of the concrete, as shown in FIG.

The sleeve 6 is made of metal and has a cylindrical shape as shown in FIG. 2. An internal thread 8 is formed on the inner peripheral surface of the sleeve 6, and four rod-shaped retainers 9 are horizontally arranged on the outer peripheral surface. I have set up. A plurality of sleeves 6 are vertically arranged at appropriate intervals while the concrete is not hardened, and a plurality of sleeves 6 are embedded so that the lower openings 1 of the anchor bolts 5 can be screwed together and the openings at the upper ends are connected to the outside of the foundation 2. To do. Since the sleeve 6 is shorter and lighter than a conventional anchor bolt, it is hard to tilt even in uncured concrete.

After the foundation 2 is formed, the anchor bolts 5 are attached to the respective sleeves 6. The anchor bolts 5 are as shown in FIG.
a and 10b are formed, and disk-shaped plate-like portions 11a and 11b are formed at one end.
The lower part 1 and the upper part 3 made of metal provided with
11a and 11b are made to face each other, and a cushioning material 12 is sandwiched between them for connection.

The plate-like portion 11b of the upper portion 3 is the receiving portion 11 of the base 4.
b. The cushioning material 12 is made of rubber having the same cross section as that of the plate-shaped portions 11a and 11b, or other rubber-like material, and is made into a plate-shaped material by pressing it with heat to press it or bonding it with an adhesive. It is fixed to the parts 11a and 11b.

The anchor bolt 5 is a male screw on the lower portion 1.
By attaching 10a to the female screw 8 of the sleeve 6, the sleeve 10 is attached to the sleeve 6 and is fixed to the base 2.

Next, the base 4 is supported on the upper portion 3 of each anchor bolt 5. As shown in FIG. 4, the anchor bolt 5 is formed by penetrating a portion of the upper portion 3 on which the male screw 10b is formed into a hole formed from the bottom face formed on the base 4 to the upper face, and further forming the male screw 10b. The bottom surface of the base 4 is supported by the receiving portion 11b provided below the portion. Then, the washer 13 is attached to the projecting portion of the base 4 and the nut 14 is screwed and tightened to fix the base 4 between the nut 14 and the receiving portion 11b. As a result, the base 4 is firmly fixed on the foundation 2.

Then, it is checked with a leveler whether the base 4 is fixed horizontally. If it is not fixed horizontally,
By rotating one of the anchor bolts 5 and adjusting the vertical position to correct the inclination of the base 4, the base 4 can be fixed horizontally. Therefore, it is not necessary to accurately level the top end of the foundation 2 and the labor is small.

This fixing mechanism can be used for fixing the base of general houses, buildings, and other buildings in general. In the case of a general house, the anchor bolt 5 has a lower part 1 with a length of 200 mm, an upper part 3 with a length of 120 mm, a lower part 1 and an upper part 3.
The diameter of the portion where the male screw is formed is 13 mm, and the plate-shaped portion 11
a, 11b having a thickness of 4 mm, a cushioning material 12 having a diameter of 90 mm and a thickness of about 22 mm, the sleeve 6 has a total length of 200 mm,
The inner diameter of the female screw formed may be 13 mm, and the thickness of the peripheral wall may be about 4 mm, but the invention is not limited to this, and the size may be an appropriate size according to the type and size of the building. Different shapes can be used.

The receiving portion 11b is at least the plate-like portion.
Since the thickness of 11a and 11b and the thickness of the cushioning material 12 are higher than the top of the foundation 2, there is a space between the foundation 2 and the base 4, which ensures ventilation under the floor. Therefore, it is not necessary to form a ventilation hole in the foundation 2 unlike the conventional case. Therefore, it is possible to save the labor of forming the ventilation opening when forming the foundation 2, and to prevent the formation of the ventilation opening from interfering with the arrangement of the reinforcing bars in the foundation 2.

Further, conventionally, since the corner portion 15 of the foundation 2 causes a decrease in strength, it is impossible to form a ventilation port, which results in insufficient ventilation, which may result in a building base or Although the wood used for the floor was easy to rot and caused the generation of termites, the anchor bolt 5 according to the present invention causes a gap between the base 4 and the corner 15 of the foundation 2. , Sufficient ventilation can be secured.

Also, the upper portion 3 and the lower portion 1 of the anchor bolt 5
Are connected by the cushioning material 12, and even if an earthquake occurs or a large vehicle passes by, the vibration is absorbed by the cushioning material 12, and the lower part 1 to the upper part 3 of the anchor bolt 5 are absorbed.
I can't tell you. Moreover, since the space exists between the foundation 2 and the foundation 4, the vibration is not directly transmitted from the foundation 2 to the foundation 4.

Therefore, even if the foundation 2 shakes, the vibration is not transmitted from the foundation 2 to the base 4 through the anchor bolts 5 as it is, and a sufficient seismic isolation effect can be obtained.

[0024]

The fixing mechanism for the foundation of the building of the present invention is
With the above-mentioned structure, the anchor bolt is screwed into the sleeve embedded in the foundation to be attached, so that the anchor bolt does not tilt and the base can be easily adjusted by adjusting the vertical position of the anchor bolt. Since it can be fixed horizontally and the top end of the foundation does not need to be leveled accurately, the construction is labor-free and the cost is low.
