DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a joint structure between a pile and a building according to the present invention will be described in detail with reference to the drawings. However, although various limitations that are technically preferable for carrying out the present invention are attached to the embodiments described below, the scope of the present invention is not limited to the following embodiments and illustrated examples.

In this embodiment, a joint structure 1 between a pile P and a building built on the pile P, and a joint structure 1 between a pile P and a pillar C of a building will be described.
The joint structure 1 has a base plate 11 and a tube body 12 fixed to the lower surface of the base plate 11, as shown in FIGS. 1, 2, and 3, for example, and the tube body 12 is attached to the pile P. The connecting member 10 installed over the pile cap, the connecting plate 20 to which the pillar C of the building is fixed on the upper surface, the fastening member 30 connecting the base plate 11 and the connecting plate 20, and the base. A filling material 40 formed by filling a fluid hardening material between the board 11 and the joint plate 20, and a fluid hardening material filled between the base plate 11 and the joint board 20 for storing the fluid hardening material until the joint board 20 is filled. It is equipped with a leak prevention member 50 and the like.

The joining member 10 is a member formed by welding a steel tube 12 to the lower surface of a steel base plate 11.
Here, a disk-shaped steel plate 13 inscribed on the inner surface of the tube 12 is used as a backing metal, and the tube 12 is welded and fixed to the base plate 11. Note that the steel plate 13 serving as the backing metal may be in the shape of a donut plate inscribed on the inner surface of the tube body 12.

Elongated holes 11a (see FIG. 2) extending in a predetermined direction are formed at the four corners of the base plate 11 of the joining member 10.
Furthermore, a through hole 11b is provided in the center of the base plate 11 at a position inscribed with the inner surface of the tube body 12. In this embodiment, four through holes 11b are provided at equal intervals in the circumferential direction.
This through hole 11b is formed to penetrate through the base plate 11 and the steel plate 13 disposed on the lower surface of the base plate 11.

The tubular body 12 of the joining member 10 has a size that allows it to be placed over the pile cap with a gap between it and the pile P.
In other words, the inner diameter of the tube 12 is larger than the outer diameter of the pile P. For example, a gap of about 1 cm to several tens of cm is left between the inner surface of the tube 12 and the outer surface of the pile P, and the tube is attached to the pile cap. 12 is covered. Note that the upper end of the pile P abuts against the steel plate 13 of the joining member 10 placed over the pile head.

The through hole 11b of the base plate 11 is provided for filling the space between the inner surface of the tube body 12 and the outer surface of the pile P with a fluid hardening material. Furthermore, the filling status of the fluid hardening material can be confirmed using the through hole 11b.
Further, an annular member 60 is disposed on the outer circumferential surface of the pile P to come into contact with the lower end of the tube 12 and to hold the fluid hardening material between the inner surface of the tube 12 and the outer surface of the pile P. .
A filler 70 filled with a fluid hardening material is provided between the inner surface of the tubular body 12 and the outer surface of the pile P.

The annular member 60 is a member made of an elastic material such as rubber, and is disposed in close contact with the outer peripheral surface of the pile P.
This annular member 60 has a function of preventing the fluid hardening material filled from the through hole 11b of the base plate 11 from leaking out from between the pipe body 12 and the pile P.
Specifically, by adjusting the arrangement of the annular member 60 by moving it up and down along the pile P, the annular member 60 is brought into close contact with the lower end of the tube body 12, and the gap between the tube body 12 and the pile P is closed. It is now possible to block the
In this embodiment, the annular member 60 having a rectangular cross section is described as an example, but the annular member 60 may have another cross-sectional shape such as a circular cross section.

The joining plate 20 is a plate-like member made of steel, and has elongated holes 20a (see FIG. 2) formed in its four corners that extend in a predetermined direction.
For example, as shown in FIG. 2, the joint plate 20 is placed on top of the base plate 11 in such a way that the long holes 20a of the joint plate 20 intersect with the long holes 11a of the base plate 11 (specifically, in the perpendicular direction). It is located in
The joining member 10 and the joining plate 20 are fastened together by a fastening member 30 that communicates the long hole 11a of the base plate 11 with the long hole 20a of the joining plate 20.
In this way, the joining member 10 and the joining plate 20 are stacked so that their long holes (11a, 20a) intersect with each other, and are fastened by the fastening member 30 that communicates with each long hole. On the other hand, it is possible to perform position adjustment by moving the joint plate 20 in the direction along the elongated holes (11a, 20a).
Note that the fastening member 30 of this embodiment includes a bolt 31 and a nut 32 screwed onto the bolt 31.

The leak prevention member 50 is used to hold the fluid hardening material filled between the base plate 11 and the joint plate 20 between the base plate 11 and the joint plate 20, and to store it until the joint plate 20 is filled. It is attached to the base plate 11 with bolts 31 or the like. Here, a square washer 33 is interposed between the leak prevention member 50 and the head of the bolt 31.
The leak prevention member 50 is, for example, a tub-shaped member made of steel, and has an opening 50a (see FIG. 1) in the center of its bottom plate, through which the tube 12 of the joining member 10 is inserted.
Further, a bolt hole 50b (see FIG. 3) through which the bolt 31 of the fastening member 30 is inserted is formed in the bottom plate on the outer edge side of the opening 50a. In this embodiment, four bolt holes 50b are formed.
In addition, in this embodiment, the leak prevention member 50 which consists of one member is used, but the leak prevention member 50 used in the aspect which joined two or more parts may be sufficient.

The diameter of the opening 50a of the leak prevention member 50 is formed to be larger than the outer diameter of the pipe body 12, and when adjusting the position of the joint plate 20 with respect to the joint member 10 (base plate 11), The arrangement of the leak prevention member 50 can be changed depending on the position of the fastening member 30 moving along the hole 11a. Note that this opening 50a is formed smaller than the base plate 11.
Further, the diameter of the bolt hole 50b of the leak prevention member 50 is formed to be approximately the same size as the diameter of the bolt 31, so that the fluid hardening material leaking from the elongated hole 11a of the base plate 11 can be absorbed by the bottom plate of the leak prevention member 50. It has a structure that is closed with a bolt 31.
Note that the bolt hole 50b of the leakage prevention member 50 may be a loose hole or an elongated hole. In this case, the rectangular washer 33 interposed between the leak prevention member 50 and the head of the bolt 31 functions as a member for blocking the fluid hardening material.
Further, if necessary, a nut may also be screwed onto the upper surface of the base plate 11.

Next, a procedure for constructing the joining structure 1 of this embodiment will be explained.

First, the pipe body 12 of the joining member 10 is installed so as to cover the pile head of the pile P that is erected in the ground.
At this time, as shown in FIGS. 4 and 5(a), use a guide member G that is inserted into the through hole 11b of the base plate 11 and whose tip protrudes below the lower end of the tube body 12. .
This guide member G is formed in a shape that prevents it from falling through the through hole 11b.
Then, with the guide member G, which is inserted through the through hole 11b of the base plate 11 and protrudes below the lower end of the pipe body 12, along the outer surface of the pile P, the pipe body 12 of the joining member 10 is attached to the pile P. Cover the top of the pile.
By doing so, the joining member 10 can be installed on the pile P so that the distance between the inner surface of the tubular body 12 and the outer surface of the pile P is equal over the entire circumference.
In this embodiment, four through holes 11b are provided at equal intervals in the circumferential direction, and the guide member G is inserted through the through holes 11b, but three through holes 11b are provided at equal intervals in the circumferential direction. Even if the guide member G is inserted through the through hole 11b, the distance between the inner surface of the tube body 12 and the outer surface of the pile P can be made equal over the entire circumference.

Next, as shown in FIG. 5(b), the guide member G is pulled out from the through hole 11b.
Then, the annular member 60 previously disposed on the lower side of the pile P is moved upward, and the annular member 60 is brought into contact with the lower end of the tubular body 12 of the joining member 10.
Note that the annular member 60 is arranged in advance on the upper side of the pile P, and when the tubular body 12 of the joining member 10 is placed over the pile head of the pile P, the annular member 60 is pushed down by the tubular body 12. The annular member 60 may be brought into contact with the lower end of the tube body 12.

Next, as shown in FIG. 6A, a fluid hardening material (for example, a grout material such as mortar) is filled between the inner surface of the tube body 12 and the outer surface of the pile P through the through hole 11b of the base plate 11. It is preferable to use a funnel when filling the space between the inner surface of the tubular body 12 and the outer surface of the pile P with the fluid hardening material from the through hole 11b.
Then, the fluid hardening material filled between the tubular body 12 and the pile P is hardened to form the filler 70. By forming the filler 70 between the tubular body 12 and the pile P, the joining member 10 is fixed to the pile cap of the pile P.

Next, as shown in FIG. 6(b) and FIG. 2 (FIG. 3), the top of the base plate 11 is aligned so that the long hole 20a of the joint plate 20 intersects (perpendicularly) the long hole 11a of the base plate 11. The joining plates 20 are arranged so as to overlap each other, and the joining members 10 and the joining plates 20 are fastened together by a fastening member 30 in which the elongated holes 11a of the base plate 11 and the elongated holes 20a of the joining plates 20 communicate with each other.
At this time, the bonding member 10 and the bonding plate 20 are fastened together with a pad 40a of non-shrinkable mortar called manju mortar being sandwiched between the base plate 11 and the bonding plate 20. This makes it easier to adjust the position and angle of the joining plate 20 with respect to the joining member 10.
Further, as shown in FIG. 6(b), when the joining member 10 and the joining plate 20 are fastened together using the fastening member 30, the leakage prevention member 50 is attached to the base plate 11.

In this way, after the joining member 10 and the joining plate 20 are fastened and the leakage prevention member 50 is attached to the base plate 11, a fluid hardening material (for example, grout material such as mortar) is placed between the base plate 11 and the joining plate 20. Fill it.
Note that the edge of the tub-shaped leak prevention member 50 is designed to be located at a higher position than the joining plate 20, so that the fluid hardening material can be filled until the joining plate 20 and the fastening member 30 are filled.
Then, the fluid curable material filled inside the tub-shaped leak prevention member 50 is cured so that the fluid curable material is filled between the base plate 11 and the joint plate 20, as shown in FIG. A filling material 40 is formed. By forming the filler 40 between the base plate 11 and the joint plate 20 and inside the leak prevention member 50, the joint plate 20 (column C) is fixed to the joint member 10 (base plate 11).
Through such a procedure, the joint structure 1 between the pile P and the pillar C of the building can be constructed.
Note that the fastening member 30 embedded in the filler 40 is less likely to be rusted, and the fastening member 30 is less likely to deteriorate.

In such a joint structure 1, after the pipe body 12 of the joint member 10 is placed on the pile cap of the pile P, a fluid hardening material is filled between the pipe body 12 and the pile P to form the filler 70. Since the joining member 10 can be fixed to the pile P in this manner, the joining work is simpler than the joining work of attaching a pile cap to the pile P using many bolts as in the above-mentioned conventional technology. , the joining member 10 can be installed on the pile P with a simple operation.

Furthermore, the joining member 10 and the joining plate 20 in this joining structure 1 are stacked so that their long holes (11a, 20a) intersect (orthogonal to each other), and are fastened by fastening members 30 that communicate with the respective long holes. Therefore, it is possible to adjust the joint plate 20 by moving it in the direction along each elongated hole (11a, 20a), and to adjust the position and angle of the joint plate 20 with respect to the joint member 10. With this, the position and angle of the pillar C relative to the pile P can be adjusted.
If the positions and angles are adjusted using the intersecting elongated holes (11a, 20a) as described above, the arrangement of the pillars C relative to the piles P can be adjusted relatively easily.

As described above, with the joining structure 1 of this embodiment, the pile P and the pillar C of the building can be joined with good workability.

Note that the present invention is not limited to the above embodiments.
For example, as shown in FIG. 7(c), the annular member 60 disposed on the outer circumferential surface of the pile P is connected to the pile P and the tube body 12 so as to come into contact with the inner surface of the tube body 12 of the joining member 10. It may be inserted in between.
In this case, as shown in FIGS. 7(a), 7(b), and 7(c), the guide member G, which is inserted through the through hole 11b of the base plate 11 and protrudes below the lower end of the tube body 12, is attached to the outer surface of the pile P. The guide member G is pulled out from the through hole 11b while the tubular body 12 of the joining member 10 is placed over the pile head of the pile P in a state along the guide member G.
In this process, the annular member 60 is inserted between the pile P and the tubular body 12 while being elastically deformed so as to be crushed.
In this way, if the annular member 60 is inserted between the pile P and the tube 12 so as to come into contact with the inner surface of the tube 12 of the joining member 10, the fluidity hardening filled from the through hole 11b The material can be more suitably held between the inner surface of the tube body 12 and the outer surface of the pile P.

Further, the present invention is not limited to the above embodiments.
For example, as shown in FIG. 8, a leakage system is constructed of a bucket-shaped member 51 attached to the upper surface of the base plate 11 and a back plate member 52 attached to the lower surface of the base plate 11 at a portion that closes the elongated hole 11a. The joining structure 1 may include a stopper member 50.
Even with such a joining structure 1, the pile P and the pillar C of the building can be joined with good workability.

Further, the present invention is not limited to the above embodiments.
For example, as shown in FIGS. 9 and 10(a), a guide member G having a tip end bent at a predetermined curvature may be used.
By inserting a guide member G having a curved tip into the through hole 11b of the base plate 11 and arranging the guide member G outward so that the tip of the guide member G is spread outward, the pile cap of the pile P can be This makes it easier to guide the tube body 12 of the joining member 10.
In particular, this guide member G is formed to have a curvature that allows its curved tip to follow the outer surface of the pile P, so as shown in FIGS. If G is rotated and pulled up, the tip of the guide member G can be pulled out while slidingly contacting the pile P.
Even in this case, the joining member 10 can be installed on the pile P so that the distance between the inner surface of the tubular body 12 and the outer surface of the pile P is equal over the entire circumference.

Further, for example, as shown in FIGS. 11(a) and 11(b), a joining member 10 may be used in which a tube-side protrusion 12a is provided on the inner surface of the tube 12.
The tube body side protrusion 12a is provided to maintain a predetermined distance between the inner surface of the tube body 12 and the outer surface of the pile P. It projects toward the outer surface of the pile P so as to come into contact with it.
The tubular body side protrusion 12a here is formed in an annular shape along the inner surface of the tubular body 12.
If the joining member 10 is provided with such a tube-side protrusion 12a, the joining member 10 is attached to the pile P so that the distance between the inner surface of the tube body 12 and the outer surface of the stake P is equal over the entire circumference. It can be installed in

For example, as shown in FIGS. 12(a) and 12(b), a joining member 10 in which a pipe body side protrusion 12a is provided on the inner surface of the pipe body 12 is attached to a pile P in which a pile side protrusion 12b is provided on the outer surface. may be installed.
The tube side protrusion 12a and the pile side protrusion 12b are provided to maintain the distance between the inner surface of the tube 12 and the outer surface of the pile P to a predetermined length.
The tube side protrusion 12a here is formed in a spiral shape along the inner surface of the tube body 12, and the pile side protrusion 12b is formed in a spiral shape along the outer surface of the pile P.
When this joining member 10 is placed over the pile head of the pile P, the joining member 10 may be screwed onto the pile head of the pile P.
When the joining member 10 is installed on the pile P, the tube-side protrusions 12a protrude toward the outer surface of the pile P so as to come into contact with the outer surface of the pile P, and the pile-side protrusions 12b protrude from the inner surface of the tube 12. It has a shape that protrudes toward the inner surface so as to come into contact with the inner surface.
Further, in a state where the joining member 10 is installed on the pile P, the pile-side protrusion 12b on the outer surface of the pile P is located at a higher position than the tube-side protrusion 12a on the inner surface of the tube body 12.
Even in this case, the joining member 10 can be installed on the pile P so that the distance between the inner surface of the tubular body 12 and the outer surface of the pile P is equal over the entire circumference.

In particular, as shown in FIG. 12(b), when the tube-side protrusion 12a of the joint member 10 (pipe body 12) installed on the pile P is located at a lower position than the pile-side protrusion 12b of the pile P, If a fluid hardening material is filled between the inner surface of the tube body 12 and the outer surface of the pile P through the through hole 11b of the base plate 11 to form the filler 70, the tube body side protrusion 12a and the pile side protrusion 12b can be formed. The compression struts formed by the filler material 70 between the piles P and the joint member 10 increase the joint strength, and the yield strength of the joint structure 1 increases.

Further, for example, as shown in FIGS. 13(a), (b), and (c), a pile P is provided with a pile side protrusion 12b on the outer surface, and a tube body side protrusion 12a is provided on the inner surface of the tube body 12. You may make it install the joining member 10.
Here, four tube-side protrusions 12a are formed at equal intervals in the circumferential direction along the inner surface of the tube body 12, and four pile-side protrusions 12b are formed at equal intervals in the circumferential direction along the outer surface of the pile P. has been done.
When installing this joining member 10 on the pile cap of the pile P, as shown in FIGS. After the joint member 10 is placed on the pile head of the pile P, the joint member 10 may be rotated about the pile P as shown in FIGS. 13(b) and 13(c). Here, the joining member 10 is rotated by 45 degrees.
As shown in FIG. 13(c), the tube-side protrusion 12a of the joint member 10 (pipe body 12) installed on the pile P is located at a lower position than the pile-side protrusion 12b of the pile P, and overlaps in the vertical direction. In this case, if a fluid hardening material is filled between the inner surface of the tube body 12 and the outer surface of the pile P from the through hole 11b of the base plate 11 to form the filler 70, the tube body side protrusion 12a Due to the compression strut formed by the filler 70 between the pile P and the pile-side protrusion 12b, the joint strength between the pile P and the joint member 10 is increased, and the yield strength of the joint structure 1 is improved.

Note that if the tubular body side protrusion 12a of the tubular body 12 of the joining member 10 is divided into a plurality of parts and is formed at a position where the guide member G inserted from the through hole 11b of the base plate 11 does not hit, then FIG. As shown in 14, the pipe body 12 of the joining member 10 can be placed over the pile head of the pile P by using the guide member G in combination.

Note that the application of the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the present invention.
