Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a foundation and a hiring pile and a foundation structure used for constructing the foundation. More specifically, the present invention relates to a concrete in which cracks and cracks are not generated in concrete forming a pile.

[0002]

2. Description of the Related Art When constructing a structure, a foundation is laid to make the ground solid. Piles are usually built into the foundation. Piles are particularly useful when laying a foundation on soft ground, as they can distribute the weight of the structure into the ground or deep into the ground.

As the types of piles, wood piles, reinforced concrete piles and the like are generally known. The type of pile built on the foundation differs depending on the condition of the ground, the structure to be constructed, and the like. For example, wooden piles are often used as the foundation for buildings such as relatively small detached houses. The so-called pine wood such as Japanese red pine and Japanese black pine is mainly used for wood used for wooden piles.

[0004] The wooden pile is usually peeled off from the bark so that many irregularities such as nodes appear on the surface, and further, the side having a larger outer diameter (in this specification, it may be described as "base").
Is placed on the ground with the side having a small outer diameter (in this specification, sometimes referred to as “tip”) down. As a result, it is difficult to slip and the settlement resistance can be increased, so that it is possible to endure the weight of the building and make it difficult for the settlement to occur. However, wooden stakes are relatively small parts of groundwater and the like near the ground surface (hereinafter, for convenience,
The “water-free part” has a disadvantage that it is easily corroded because it is easily exposed to air.

[0005] On the other hand, a reinforced concrete pile is built in the ground and then has a relatively large amount of an underwater portion or a portion of groundwater below the portion (hereinafter referred to as a "normal water portion" for convenience. It is difficult to corrode even after a long period of time on both sides of the ground, which is usually less than about 1.5 m deep from the ground surface. However, there is a drawback that it is easy to sink.

In order to solve the above-mentioned problem, the present inventor has proposed a construction in which the normal water section A is installed at the time of building as shown in FIG.
The pile 9 in which the portion corresponding to 1 is made of wood (wood pile 90) and the portion corresponding to the anhydrous portion B1 is formed of concrete 91 has been developed. According to the pile 9, it is possible to simultaneously achieve both settlement prevention and corrosion prevention after driving into the ground.

[0007]

However, the above-mentioned pile has the following problems. That is, since the pile 9 is formed by connecting the concrete 91 to the wooden pile 90 via the connecting member 92, when the pile 9 is pushed into or driven into the ground, the wooden pile 90 and the concrete are connected. Excessive force is likely to be applied to the joint with the joint 91, which may cause cracks or cracks in the concrete 91 near the joint.

An object of the present invention is to provide a function equivalent to that of the above-mentioned conventional pile built on the ground, and to provide a foundation construction method and a foundation in which cracks and cracks are not generated in the concrete constituting the pile. It is an object of the present invention to provide a hiring pile and a foundation structure used for construction of a building.

Arranging a hollow form member in such a manner that the pile member and the form member are erected together in the ground, and a step of pouring and solidifying concrete inside the form member. It is a method of constructing a foundation, characterized in that:

According to a third aspect of the present invention, there is provided a method for constructing a foundation on which a structure is constructed, wherein a pile member having a connecting member protruding from a base surface is inserted into the inside of the pile member so that the connecting member is inserted into the outside. While being built in the ground by a hiring pile into which a hollow form member is inserted, the form member is arranged in the hollow portion through which the pile member has passed so that the connection member is housed inside. A step of removing the hired pile from the ground and a step of pouring and solidifying concrete into the formwork member.

According to a fourth aspect of the present invention, there is provided a method of constructing a foundation on which a structure is constructed, wherein the connecting member is housed on a pile member having a connecting member projecting from a base surface. By placing a hollow form member in such a manner that the connection member is inserted thereinto and the form member is inserted into the outside, the pile member and the form member are ground together. A method for constructing a foundation, comprising: a step of removing the hiring pile from the ground; and a step of pouring and solidifying concrete into the inside of the form member.

According to a fifth aspect of the present invention, there is provided the method for constructing a foundation according to the first, second, third or fourth aspect, wherein the pile member is a wooden pile from which bark is peeled. .

According to a sixth aspect of the present invention, the pile member is formed such that the upper side has a larger diameter and the diameter gradually decreases toward the lower side. A third aspect of the present invention is a method for constructing a foundation according to the fourth or fifth invention.

According to a seventh aspect of the present invention, there is provided an employment pile used when a pile member having a connecting member protruding from a base surface is built into the ground, from the surface where the pile member abuts to the inside. A hiring stake for use in foundation construction, wherein a housing portion into which the connecting member can be inserted is formed.

According to an eighth aspect of the present invention, a guide surface formed so as to be narrowed inward is provided on an inner surface of the housing portion near a surface where the pile member contacts. A hiring pile used for construction of a foundation according to the seventh invention.

According to a ninth aspect of the present invention, there is provided a form pressing member which presses the form member when the pile member is laid and buries the form member in the ground. A hiring stake used for construction of a foundation according to the seventh or eighth invention, wherein the hiring stake is movable and its installation location can be adjusted.

According to a tenth aspect of the present invention, there is provided a foundation structure on which a structure is constructed, the pile member being buried in the ground and having a connecting member protruding from a base surface thereof; In the hollow portion where the member has passed, a hollow form member arranged so that the connecting member is housed therein, and concrete provided inside the form member are provided. Characterized by the following:

In the present invention, "base surface" indicates the end surface of the base of the pile member. .

The term "building" as used in the present invention means that a pile member is pushed (press-fitted) or hammered into a ground. In addition, "building direction"
Means the direction in which the pile member is inserted into the construction site.

As the pile member, a wooden pile is usually used for the reasons and costs described above. However, the present invention is not limited to this.A lot of irregularities are provided on the surface like a wooden pile, and the pile is driven into the ground with the large outside diameter on the top and the small outside diameter on the bottom. As long as the settlement resistance can be increased so as to endure the weight of the structure and make it difficult for the settlement to occur, a reinforced concrete pile, a steel pile, or a combination thereof may be used. Examples of the reinforced concrete pile include a centrifugal reinforced concrete pile and a centrifugal prestressed pile, and examples of the steel pile include a steel pipe pile, a spiral steel pipe pile, and an H-shaped steel pile.

A rod is usually used as the connecting member. The rod-shaped body includes, for example, a rod-shaped reinforcing bar, a reinforcing bar having a convex band formed on its surface, or a reinforcing bar having a cross-section of an appropriate shape such as a circle, a square, a rhombus, or a star, so-called deformed reinforcing bar. Further, for those having a circular, square, rhombic, or star-shaped cross-section, not only a solid body but also a hollow body (for example, a pipe) may be used. In particular, when the connecting member is a hollow body and the pile member is a wooden pile, it is possible to drive the connecting member without causing a crack or the like in the wooden pile without making a hole for providing the connecting member in the wooden pile. Since it is possible, work efficiency can be improved.

As a method of driving a pile member into the ground,
There are a hitting method, a vibration method, a press-in method, and the like.

(Operation) While a pile member having a connecting member protruding from a base surface is built in the ground, the connecting member is housed inside a hollow portion through which the pile member has passed. Arranging a hollow form member, or arranging a hollow form member on a pile member having a connection surface protruding from a base surface such that the connection member is accommodated therein; The step of embedding the pile member and the formwork member together in the ground, and the step of pouring and solidifying concrete into the inside of the formwork member comprises a joint between the pile member and the concrete. The pile can be provided on the ground without causing cracks or cracks in the ground. The pile formed by the method for constructing a foundation according to the present invention has substantially the same structure as a state in which a conventional pile is laid on the ground, and therefore has the same function.

Further, since a hollow form member is disposed in a hollow portion formed by passing the pile member, the form member becomes a wall, and the hollow portion is buried by the earth pressure of the ground or the like. I won't. Therefore, the concrete can be sufficiently poured into the hollow portion, and the strength of the formed pile does not lack reliability compared to the conventional pile. Note that, on a pile member having a connecting member protruding from a base surface, a hollow form member is arranged so that the connecting member is housed therein, and the pile member and the form member are separated from each other. Even those built together in the ground, a hollow portion is formed in the place where the above-mentioned pile member passed in the ground.

The pile member is a bark-peeled wooden pile,
Since the surface has a natural uneven portion such as a node, the settlement resistance is large, and the settlement of the pile can be effectively prevented.

The pile member whose upper side is formed to have a large diameter and whose diameter is gradually reduced toward the lower side is built up with the tip of the small diameter side down, so that the resistance at the time of installation is improved. Can be reduced and work becomes easier. Also, after construction, it is possible to increase the resistance against settlement by making it less slippery, so that it is possible to withstand the weight of the building and make it difficult for the settlement to occur.

A hiring pile used when a pile member having a connecting member protruding from a base surface is built into the ground, and a housing portion into which the connecting member can be inserted from a surface in contact with the pile member to the inside. Is formed, the connecting member can be accommodated in the accommodating portion, and the connecting member can be kept out of the way when the pile member is erected. Therefore, the hiring pile can be brought into contact with the contacting surface with the end face of the upper part of the pile member, and the pile member can be pushed into the ground and built.

A hiring stake provided with a guide surface formed so as to be narrowed inward on the inner surface of the housing portion near the surface where the stake member abuts, especially when the stake member is a wooden stake or the like. When it is deformed by pressing, when pushing the pile member into the ground by applying a pressing force,
A portion of the base surface of the pile member that abuts the hiring pile and does not correspond to the accommodation portion can be compressed and deformed. With this, a portion corresponding to the accommodation portion in the base surface of the pile member is raised upward, and it can be deformed so as to be narrowed inward along the guiding surface provided on the hiring pile, and from the guiding surface. By the generated reaction force, a pressing force can be applied from the periphery toward the central portion in the axial direction of the housing portion. Therefore, the connection member provided on the pile member can be fixed or substantially fixed by being tightened by the pile member.

[0030] A formwork pressing member is provided for pressing the formwork member when embedding the pile member so as to be embedded in the ground, and the formwork pressing member is movable in the mounting direction so that the installation location can be adjusted. Since the installation position of the mold pressing member can be arbitrarily adjusted, it is possible to cope with various mold members having different lengths.

Reference numeral 3 denotes a wooden pile which is a pile member (see FIGS. 4 to 11). The wooden pile 3 is in a state where the bark on the surface is peeled off, and has a natural uneven portion 30 such as a node. The wooden pile 3 has a base portion 31 formed with a large diameter, and gradually becomes smaller in diameter with the tip portion 32. The tip 32 is

FIG. 2 is an explanatory sectional view of a main part showing a state where the hiring pile is pushing the wooden pile. In addition, the code | symbol A has shown the anhydrous part and the code | symbol B has shown the normal water part.

With reference to FIG. 1 to FIG. 12, the procedure of the foundation construction method according to the present invention and the operation thereof will be described. With the tip 32 of the wooden pile 3 facing downward, the wooden pile 3 is erected vertically in the ground by a press-fitting method (see FIG. 4). At this time, the upper side of the wooden pile 3 is left on the ground for a required length.
Since the wooden pile 3 is built with the tip 32 on the small diameter side down, the resistance at the time of building can be reduced, and the work becomes easy. In addition, the wooden pile 3 has a larger diameter as the base 31 and also has a large number of uneven portions 30 on the surface.
The settlement of the pile can be effectively prevented. Also, after construction, it is possible to increase the resistance against settlement by making it less slippery, so that it is possible to withstand the weight of the building and make it difficult for the settlement to occur.

On the base surface of the wooden pile 3 built on the ground,
A rebar insertion hole 33 for inserting the rebar 4 is drilled to a required depth in a vertical direction by a drill or the like (see FIG. 5).

The rebar 4 is inserted into the rebar insertion hole 33 (see FIG. 6). The outer diameter of the reinforcing bar insertion hole 33 is
It is formed so as to have a slightly larger diameter than the outer diameter. Therefore, the rebar 4 is not fixed to the wooden pile 3 only by being inserted into the rebar insertion hole 33.

The hire pile Y is lifted by the wire rope 5, the sleeve 2 is inserted into the outer peripheral portion of the hire pile main body 1, and the upper end edge of the sleeve 2 is put on the cover 120 to adjust the installation position of the sleeve pressing member 12. . The sleeve pressing member is slidable and movable in the longitudinal direction of the hiring pile main body 1, tightens the screws of the fixtures 122... Along the screw groove, and presses the tip of the screw against the hiring pile main body 1. By doing so, it can be fixed to the hiring pile main body 1. Therefore, the installation position of the sleeve pressing member 12 can be adjusted arbitrarily, and can be adapted to sleeves of various lengths.
Furthermore, since the sleeve pressing member can be removed from below by moving it in the longitudinal direction of the hiring pile main body 1, the outer diameter can be changed by replacing the cover pressing member with a sleeve pressing member having a different outer diameter. Can be adapted to various sleeves different from each other.

Then, the hiring stake Y is lowered from above in the state described above, and the reinforcing bar 4 is inserted into the insertion tube 130, and is accommodated in the accommodating portion 100 (see FIG. 7). This makes it possible to prevent the reinforcing bar 4 from being in the way when the wooden pile 3 is built. Therefore, the hiring pile Y can make the contact surface 13 abut on the base surface of the wooden pile 3 and push the wooden pile 3 into the ground to be built.

The hire pile Y is pushed down by applying force in the vertical direction by a pile driver or the like, and the wooden pile 3, the reinforcing bar 4, and the sleeve 2 are buried in the ground (see FIG. 8). At this time, the wooden pile 3 is erected so that the entire length of the wooden pile 3 is located in the normal water section B and the sleeve 2 is located in the anhydrous section A. It is well known that wood does not generally have high hardness and deforms when subjected to considerable pressing force.

The contact surface 13 of the hiring pile body 1 is
When the wooden stake 3 is pressed into the ground by applying a pressing force to the wooden stake 3, a portion of the base surface of the wooden stake 3 that abuts the hire stake Y and that does not correspond to the insertion pipe 130 is pressed by the pressing plate 1.
32 can be pressed to compress and deform. Thereby, a portion corresponding to the insertion tube 130 in the base surface of the wooden pile 3 is raised upward, and is deformed so as to be narrowed inward along the guiding surface 131 formed on the inner surface of the insertion tube 130. Thus, the reaction force generated from the guide surface 131 can apply a pressing force from the periphery toward the center in the axial direction of the storage unit 100. Therefore, the reinforcing bar 4 inserted into the wooden pile 3 can be tightened and fixed by the wooden pile 3.

In addition, in the contact surface 13 of the hire pile main body shown in the present embodiment, since the insertion pipe 130 and the lower end edge of the hire pile main body 1 are particularly protruded from the pressing plate 132, the wooden pile 3 The area for pressing the base surface is small, and an extremely high pressing force is applied to the contacted portion. In other words, since the wooden pile 3 pressed by the hire pile Y has a large deformation of the base 31, the force for fastening and fixing the rebar 4 inserted in the wooden pile 3 by the wooden pile 3 can be increased. 12).

The hire pile Y is lifted by the wire rope 5 and pulled out from the ground to form a hollow portion 6 (FIG. 9).
reference). Since the sleeve 2 serves as a wall, the hollow portion 6 is not buried by the earth pressure of the ground or the like. Therefore, the concrete 7 can be sufficiently poured into the hollow portion 6, and the strength of the formed pile does not lack reliability compared to the conventional pile. In particular, when construction is performed on soft ground, the hollow portion 6 is likely to be filled with earth pressure unless there is anything that becomes a wall because the ground is soft. In this case, the concrete filling amount may not be sufficient, and the strength of the pile may not be reliable.

In order to easily pour the concrete 7, the soil near the surface where the wooden pile 3 was erected is filled with the hollow portion 6.
Then, concrete 7 is poured into the buried sleeve 2 to fill the reinforcing bar 4 (see FIG. 10). The work of pouring concrete becomes easier when a funnel or the like is used. When the concrete 7 solidifies, the concrete 7 is integrated with the wooden pile 3 via the reinforcing bar 4 (see FIG. 11). In addition, the code | symbol K has shown the basic structure. By pouring the concrete 7 into the hollow portion 6 and solidifying it, a pile integrally provided with the concrete 7 can be formed on the ground.

According to this construction method, after the wooden pile 3 is built, the concrete 7 is poured and solidified.
When the pile is built, there is no concrete 7 and the problem unlike the conventional pile does not occur. That is, no excessive force is applied to the joint between the wooden pile 3 and the concrete 7, and no crack or crack is generated in the concrete 7.

The terms and expressions used in the present specification are merely illustrative and not restrictive. Terms and expressions equivalent to the features described in this specification and some of them are not limited to those described above. There is no intention to exclude expression. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
