Abstract

PROBLEM TO BE SOLVED: To make it impossible to pull out with ease during a strong wind, earthquake and so forth by providing a base where a plurality of through holes penetrating in the slanting direction is formed and inserting slidably a plurality of pins longer than the through holes into each through hole respectively and pressing each pin against the ground with a pressure plate. SOLUTION: A plurality of through holes 2B, which penetrate in the slanting direction between the top 2A and the bottom, are formed on a disk-shaped base 2. The through holes 2B are bored in such a direction that they may be oriented to the inside of the base 2. A plurality of pins 3 satisfactorily longer than the through holes 2B are slidably inserted into the through holes 2B respectively. The pins 3 inserted into the through holes 2B are adapted to project out from the bottom of the base 2 in an intersecting state. A bolt 4 is vertically anchored with the central part of the top of the base 2 of a foundation pile stated above. A pressure plate 5 is fitted in the screw 4A so that it may move vertically. A floor material 8 of a house is fixed with a bolt 7 locked with the pressure plate 5 with a nut 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation pile for fixing a prefabricated house, a simple house such as a temporary house or other structures to the ground.

[0002]

2. Description of the Related Art Conventionally, when fixing a building as described above to the ground, a method has been used in which a bar-shaped pile is driven vertically into the ground and the building is connected thereto.

[0003]

When a structure is fixed to the ground by such a method, there is no particular problem in normal times. For example, when a strong wind hits the structure, the structure shakes. The force that pulls out from the ground acts on the pile, and the connection between the pile and the ground becomes loose.
Then, when an extremely strong wind hits the structure due to a gust, a typhoon, or the like, there is a problem that the pile may be detached from the ground and the structure may be blown away. Further, according to the conventional method, there is a problem that the pile is easily removed from the ground even when an earthquake having a large seismic intensity occurs.

An object of the present invention is to solve the above-mentioned problems and to provide a foundation pile for fixing a structure which does not easily come out of the ground when a strong wind, an earthquake or the like occurs.

[0005]

In order to achieve the above object, the foundation pile according to the present invention is formed with a plurality of through holes that obliquely penetrate between one surface and the other surface. A base portion, a plurality of pins that are longer than the length of the through holes and are slidably inserted into the through holes, and a pressure plate that presses the pins toward the ground side. It is what

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings.

[0007]

1 and 2 show an embodiment of the present invention. In the figure, reference numeral 1 is a foundation pile according to the present invention,
It consists of a disk-shaped base 2 and a plurality of pins 3. More specifically, the base 2 has a circular shape with a diameter of several 10 cm, for example, and a plurality of through holes 2B penetrating obliquely between the upper surface 2A and the lower surface thereof are formed. The through hole 2B is
It is perforated in such a direction as to face the inside of the base portion 2. A plurality of pins 3 that are sufficiently longer than the length of the through hole 2B are slidably inserted into the through hole 2B. As can be understood from FIG. 1, the plurality of pins 3 inserted into the through holes 2B project from the lower surface side of the base 2 in a state of intersecting each other. A bolt 4 is vertically fixed to the central portion of the upper surface of the base portion 2 of the foundation pile 1 as described above, and the pressure plate 5 is vertically movably fitted to the screw portion 4A. A nut 6 is fitted in the screw portion 4A protruding from the pressure plate 5.
Further, a bolt 7 having a screw portion 7A is vertically fixed to the pressure plate 5.

The foundation pile 1 constructed as described above is used as follows. That is, for example, on the ground where a prefabricated house is desired to be installed, first place the base 2 at positions corresponding to the four corners of the house, insert the pin 3 into the through hole 2B, and hammer the pin 3 into the ground. The base 2 is temporarily fixed to the ground. In this state, the pressure plate 5 is fitted to the threaded portion 4A of the bolt 4, and then the floor material 8 of the house is fixed to the bolt 7 of the pressure plate 5 with the nut 9. Then, the weight of the floor material 8 is applied to the pressure plate 5, the pressure plate 5 is lowered, and the lower surface thereof is the head 3 of the pin 3.
Touch A and push pin 3 into the ground. As a result, the pins 3 are in a state in which they open up and take roots in the ground. Then, when the pin 3 is sufficiently embedded in the ground, if the nut 6 is tightened, the floor material 8 is securely fixed to the ground. Next, if other building materials and the like are attached to the floor material 8, the house is completed. Foundation pile 1
The house fixed to the ground by the pin 3 as described above
Since it is inserted diagonally into the ground, it will not float up from the ground due to gusts or strong winds.

[0009]

FIG. 3 shows another embodiment of the present invention. Here, the through hole 11A of the base portion 11 of the foundation pile 10 is formed in the opposite direction to the case of the first embodiment, that is, toward the outside of the base portion 11. Therefore, the pins 3 are designed to expand without crossing each other. Foundation pile 10
Also in the case of the above configuration, the same operational effect as that of the first embodiment can be obtained.

[0010]

FIG. 4 and FIG. 5 show still another embodiment of the present invention. In this embodiment, a spherical concave surface 13A is formed on the lower surface of the pressure plate 13, and the head 3A of the pin 3 is pressed by this concave surface 13A. According to such a structure, while the pressure plate 13 descends, the load is always efficiently applied to the head 3A of the pin 3, and the force of the pin 3 entering the ground is increased.

Although the present invention has been described with reference to the specific embodiments as described above, the present invention is not limited to this, and a person skilled in the art can claim the invention. It goes without saying that various changes and modifications can be made without departing from the above.

[0012]

According to the present invention, the foundation piles are difficult to slip out of the ground even if the structure is greatly shaken due to a strong wind, an earthquake, etc. Therefore, the structure is blown away by the strong wind or is displaced by the earthquake. Is prevented from moving,
Thus, the safety of humans living in the building and the prevention of damage to the building itself and the contents inside the building can be prevented.
