BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base which is installed between the ground and Daihiki to maintain a constant height of the floor when building a house or the like.

[0002]

2. Description of the Related Art Conventionally, when building a house or the like,
After installing the base, it is a general method to measure the distance between the base and Daihiki and cut the floor to the length and hang it on the upper part of the base. However, when the conventional construction method is applied, the foundation is lowered due to the subsidence of the ground, and the floor surface is also lowered accordingly, causing distortion in the building. Therefore, the applicant invented a foundation that keeps the height of the floor constant as shown in Japanese Patent Publication No. 03-40769 so that the floor does not lower even if the ground lowers due to subsidence. This invention has a structure in which a hole for inserting a floor girder into the upper part of the base and a sand puddle portion for inserting sand around the floor girder are provided, and the floor girder is inserted into the base to insert fine sand into the sand puddle. ing.

[Problems to be Solved by the Invention]
According to the invention shown in -40769, when installing the foundation which keeps the height of the floor constant, since the floor is made of square prisms, after inserting the floor into the foundation, from the gap between the upper surface of the foundation and the floor. When the sand was put in, it was difficult for the sand to enter the bottom of the floor, so that it took time for the sand to uniformly enter the bottom of the floor. On the other hand, even if the base is fixed vertically to the ground, and then the floor is fixed horizontally with nails from the nail holes provided in the stopper plate, if the ground is not horizontal The central axis of the base was tilted with respect to the central axis, and as a result, a stress was generated to tilt the floor.

[0004]

In order to solve the above-mentioned problems, a screw is provided outside the upper edge of the cylindrical body having an upper opening and a plurality of ribs inscribed, and a bottom wall is provided at the lower part. A large hole is formed in the center of the bottom wall, an upper floor with a plurality of small holes formed in the outer periphery of the large hole, and one end surface of the cylindrical body with screws on the inner surface are approximately parallel and approximately perpendicular to the central axis. A plurality of grips on the outer circumference of the cylindrical body, and a screw between the one end face of the outer circumference and the grip, and the other end face to the grip. In the peripheral part, a joint provided with a screw in the opposite direction to the screw,
The upper floor bracket was connected to the fixed body, and the upper floor bracket was inserted into the inner surface of the lower floor bracket having a bottom plate provided at the lower portion of the cylindrical body having an opening at the upper portion and circumscribing a plurality of ribs.

[0005]

With the base for keeping the height of the floor constant according to the present invention, when the ground subsides, the lower floor fixed to the concrete base on the ground goes down and the upper floor is connected to the upper part. Since the fixed body is largely fixed by nails, a gap is formed in the upper part of the dry sand poured into the bottom wall of the upper floor and the lower wall of the lower floor. Then, the dry sand in the sand pool on the inner surface of the upper floor and the dry sand between the inner surface of the lower floor and the outer surface of the upper floor flow into the gap to maintain the level position of Daihiki installed at the time of construction. In addition, since an appropriate gap was provided between the outer surface of the upper floor and the inner surface of the lower floor, the lower floor was fixed vertically to the ground, and then the upper edge of the upper floor was connected via a joint. When the ground is unevenly submerged with the connected fixed body fixed with a nail so that the upper floor is vertically held, the central axis of the lower floor is tilted with respect to the central axis of the upper floor. However, due to the appropriate gap provided between the outer peripheral surface of the upper floor and the inner peripheral surface of the lower floor, the upper floor can be kept vertically installed during construction.

FIG. 11 is a conceptual diagram showing a construction state of this embodiment. The lower floor paddle 2 is temporarily placed vertically on a concrete stand 30 placed on the ground. After screwing the screw 22 of the joint 3 into the screw 7 provided on the upper part of the upper floor bracket 1,
A screw 23 provided on the fixed body 4 is screwed into the screw 21 to integrally connect the upper floor bracket 1, the joint 3 and the fixed body 4. After the upper floor pad 1 is inserted from the bottom portion into the inner cylindrical portion of the lower floor pad 2 until the bottom wall 8 contacts the bottom plate 14 of the lower floor pad 2, the dry sand 31 or Pour cold water stones to the upper surface of the fixed body 4. Next is the floor floor 1
Is lifted and the fixing body 4 is abutted on the side surface and the bottom surface of the large pull 32, and is fixed to the large pull 32 using a nail. The lower floor bridge 2 and the concrete stand 30 are fixed by driving nails into the four anchor holes 16 provided in the bottom plate 14. Then, a gap is formed between the upper surface of the dry sand 31 flowing into the bottom plate 14 and the bottom wall 8 of the upper floor 1, so that the dry sand 31 in the upper floor 1 flows down and fills the gap. Next, a suitable hollow pipe-shaped handle or the like is inserted into the two handles 20 of the joint 3 and the joint 3 is rotated. Then, since the right screw and the left screw are screwed on the joint 3, the lower floor part 2 is pushed out in the direction of the concrete stand 30, and the fixed body 4 is pushed out in the direction of the large pull 32, respectively. It is more firmly fixed to the pull 32.
Further, in the gap between the upper surface of the dry sand 31 that has re-generated on the bottom plate 14 and the bottom wall 8 of the upper floor 1 in the same manner as described above, the dry sand 31 flows down to fill the gap.
Enforcement is complete.

FIG. 12 is a conceptual diagram showing a state in which the ground is inclined and sinking. There are two types of subsidence after construction: uniform settlement and unequal settlement. In case of uniform settlement,
Since a gap is created between the bottom plate 14 and the bottom wall 8 of the upper floor part 1, the dry sand 31 flows into this gap to fill the gap.
Therefore, the position of the Daihiki 32 set at the time of construction is maintained without lowering. In addition, in the case of uneven settlement, the upper floor 1 or the lower floor 2 may be inclined due to the inclination of
According to the present invention, since an appropriate gap is provided between the outer diameter of the upper cylindrical body portion 5 and the inner diameter of the lower cylindrical body portion 12, the lower floor part 2 is slightly inclined with respect to its central axis due to uneven settlement. However, due to the appropriate gap provided between the outer diameter of the upper cylindrical body 5 and the inner diameter of the lower cylindrical body 12, the upper floor floor 1 can be kept vertically installed during construction.

[0012]

As described above, when the base according to the present invention that keeps the height of the floor constant is used, even if the ground subsidence occurs, the gap created by the subsidence is dried as described above. Since the sand 31 is automatically filled, the floor surface can always be kept constant. In particular, the effect of preventing distortion of the building due to uneven settlement is remarkable, and opening and closing of fittings and squealing of the floor are eliminated. For this reason, the work of the craftsman to dive under the floor, which was performed to correct the distortion of the building, is no longer necessary. Even when compared with the conventional product already invented by the applicant, significant improvements have been made.
