Abstract

PURPOSE:To simplify the foundation work to perform the construction quickly at a low cost, and to facilitate the improvement of height accuracy of the groundsill located surface at each floor bundle, and to secure the sufficient ventilation under the floor, and to restrict the flow-in of the cold air without stuffing with humidity and hot air. CONSTITUTION:A foundation continuous footing, which is formed of the only outer frame, is located by a method similar with the conventional method to form a ventilation port, in which a ratproof plate is fitted in an intermediate part of the vertical direction at an appropriate position. After placing concrete in the foundation continuous footing at need, foundation stones 20 are arranged at positions for pillar. Floor bundles 10 are stood on each foundation stone 20 freely to move finely in the vertical direction and freely to fix the upper part thereof to a groundsill 23, and the groundsill 23 is fixed thereon through a connecting material 12. The ventilation port is opened and closed freely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for simplifying the foundation work of a building such as a general wooden house and improving the air permeability under the floor.

[0002]

2. Description of the Related Art Generally, in the basic construction of a building such as a wooden building, first, a hole is dug to an appropriate depth to place a split chestnut or a cobblestone, and the ground is compacted to throw away a concrete. Do the work. Then, a temporary frame is assembled and the foundation concrete is hit to form the cloth foundation 1 (FIG. 3 (B)). The cloth foundation 1 includes an outer frame 2 and a partition frame 3 that partitions the inside of the outer frame 2 vertically and horizontally.
It consists of and. Further, ventilation holes 4 are formed in the outer frame 2 of the cloth foundation 1 by denting them from the upper surface in some places, and a lattice-shaped ratproof plate 5 is attached thereto (FIG. 4 (B)).

[0003]

According to the above-mentioned conventional foundation construction method, the cloth foundation 1 is formed by vertically and horizontally continuing the inner partition frame 3 with respect to the outer frame 2, and a part of the pillar is erected. It's just that, so much of it becomes unnecessary and extra effort and cost. Not only that, but the continuous cloth foundation hinders the ventilation under the floor, and the floor boards become moist and easily damaged.
The humidity in the room also increases, and damage from molds and pests is more likely to occur. Moreover, since the conventional ventilation port 4 is formed from the upper surface of the cloth foundation, the load applied to the ventilation port 4 is applied to the lower corner 4a, and cracks are likely to occur from there (FIG. 4 (B)).
There is also a drawback.

The present invention has been made in order to solve the problems in the above-mentioned conventional basic construction method, and can be constructed quickly and at low cost, and it is possible to secure sufficient ventilation under the floor. The task is to provide a basic construction method.

[0005]

According to the present invention, a cloth foundation consisting only of an outer frame is installed in the same manner as in the conventional method, and a ventilation opening is formed in an appropriate place in the vertical center of the cloth foundation. Then
After hitting a concrete in the cloth foundation as needed, a foundation stone is arranged at a position where a pillar is erected, and on each foundation stone, a floor bundle which can be finely moved in the vertical direction and whose upper portion can be fixed to a base. The above-mentioned problem was solved by a basic construction method of a building, which is characterized by fixing a foundation on it. It is preferable that the ventilation port can be opened and closed.

[0006]

[Working] Since the cloth foundation consists only of the outer frame and there is no partition inside it, the ventilation under the floor through the ventilation port is good. Since the ventilation opening is provided in the middle of the cloth foundation in the vertical direction, the load on the ventilation opening is dispersed and cracks are less likely to occur at the corners. Since each floor bundle can be finely moved up and down, the base installation height can be adjusted with high accuracy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of the construction of a floor bundle 10 used in the present invention, the main body 11 of which is made of metal such as iron, concrete, wood or the like, and is usually formed into a square pole. The plate-like connecting member 1 is provided on the upper part of the side surface of the floor bundle main body 11 which faces each other.
2 and 13 are usually rotatably mounted. Connecting material 1
One or a plurality of stop holes 14 through which bolts, nails and the like are inserted are transparently provided at the end portions of 2 and 13. The distance between the connecting members 12 and 13 is set to match the width of the base 23. A female screw portion 15 is provided on the bottom surface of the floor bundle main body 11, and a base 16 such as a disk is provided there.
The male screw 17 which is erected upright is screwed in.

In the foundation construction method according to the present invention, the cloth foundation 18 consisting of only the outer frame is formed in the same manner as in the conventional case, and the inside of the cloth foundation 18 is rolled and solidified, and then the concrete 19 is hit. And, the foundation 20 is installed only at the place where the pillar is set up,
The floor bundle 10 is placed on it (FIG. 3 (A)). The foundation 20 is usually made of concrete, and is usually reinforced with reinforcing bars. Finally, the base 16 is fixed to the anchor bolt 16a.
Therefore, it is preferable to fix it to the foundation 20.

A ventilation opening 21 is formed in the cloth foundation 18 not in the upper surface thereof but in an intermediate portion in the vertical direction, and a lattice-shaped ratproof plate 22 is fitted therein. By providing the ventilation port 21 at the intermediate position in this way, the load applied to the ventilation port 21 is dispersed, and the corners are less likely to crack. Cloth foundation 18
Since there is no partition inside, the air circulation between the inside and outside of the cloth foundation 18 through the ventilation port 21 is good, and moisture does not accumulate under the floor. Further, the ventilation port 21 may be opened and closed by sliding it sideways. By doing so, it is possible to improve ventilation in the summer and prevent warm air from trapping under the floor, and to prevent cold air from flowing in the winter.

The floor bundle 10 placed on the foundation 20 is a base 1
6 is fixed and the floor bundle main body 11 is rotated, or the floor bundle main body 11 is pressed and the base 16 is rotated so that the height of the upper surface of the floor bundle main body 11, in other words, the base is installed. The height of the surface can be finely adjusted with high precision. When the height is determined, the bases 23 are sandwiched, the connecting members 12 and 13 are raised, and the bolts are inserted through the fixing holes 14, or
The connecting members 12 and 13 are fixed to the base 23 by hitting nails or the like. The subsequent assembly of the frame member 24 on the base 23 is performed in the same manner as in the conventional case.

[0011]

The present invention is as described above. According to the present invention, since the foundation work is simplified, it is possible to perform the work quickly and at low cost, and the height of the base installation surface in each floor bundle is high. Accuracy is easy to obtain, and since ventilation under the floor is sufficiently ensured, there is an effect that cold air can be prevented from flowing in without trapping moisture and warm air.
