DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a civil engineering construction in which a column such as a steel pipe column or a steel frame column is inserted into a steel pipe pile, concrete is cast around the column, and the steel pipe pile and the column are joined and integrated. The present invention relates to a method and an apparatus for positioning a pillar at a predetermined position in a steel pipe pile when building a pillar such as a viaduct, an elevated railway, a building, and the like.

[0002]

2. Description of the Related Art As a method of joining a steel pipe foundation pile and a column of a civil engineering building structure, a reinforced concrete foundation is provided on the steel pipe foundation pile, and the column base of the steel pipe column is fixed on this foundation with anchor bolts. It is a common construction method to fill concrete into steel pipe columns as necessary. However, recently
As a method of joining the steel pipe foundation pile and the column, the reinforced concrete foundation provided on the steel pipe foundation pile is omitted, the steel pipe pillar is inserted into the steel pipe pile and filled with concrete, and the steel pipe pile and the steel pipe column are joined and integrated, and the steel pipe foundation pile is joined. It is necessary to join the column and the pillar.

[0003] As a known technique relating to a construction method of inserting and joining a steel pipe column into a steel pipe pile, for example, Japanese Unexamined Patent Publication No.
No. 86630 proposes a joint structure between a concrete-filled steel pipe pile and a concrete-filled steel pipe column. An anchor bolt is embedded in the head of a concrete-filled steel pipe pile, and a leg of the steel pipe column is inserted into the steel pipe pile. It is disclosed that concrete is cast and joined and integrated after fixing with anchor bolts.

[0004] However, when an attempt is made to perform horizontal positioning with anchor bolts embedded in concrete in a steel pipe pile, the anchor bolts are installed in a narrow space in the steel pipe pile. It is difficult to install accurate anchor bolts
It is necessary to make the pile diameter unnecessarily large in design, which is uneconomical, and there is a problem that the installation error of the pile is arbitrarily generated, so that it is difficult to uniformly install the anchor bolts. In addition, a base plate is required on the column base to fix the anchor bolts, and the workability of the column is increased, and it is not necessary to design a large-diameter steel pipe pile to accommodate the base plate in the pile. Nevertheless, the diameter of the steel pipe pile must be increased, which causes a problem of poor economy.

[0005] Also, Japanese Patent Application Laid-Open No. 3-64008 discloses that
As a joint structure between a pillar and a pile of a building structure, it is described that the lower part of the steel pipe of the pillar is inserted into the upper part of the steel pipe of the pile and the two are joined via concrete. There is no disclosure of positioning and building.

That is, when a pillar such as a steel pipe pillar or a steel pillar is inserted into a steel pipe pile, concrete is poured around the pillar, and when the steel pipe pile and the pillar are joined and integrated, a pillar is built. Actually, a concrete construction method and apparatus for positioning the column in the horizontal direction have not been distributed so far.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for fixing a column inserted into a steel pipe pile without fixing the legs of the column such as a steel pipe column or a steel column inserted into the steel pipe pile to anchor bolts. It is an object of the present invention to provide a method and apparatus for positioning a pillar in the horizontal direction, which can be positioned at a horizontal position of the pillar and can be erected.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

According to the present invention, when the column is installed, the installation position of the column is determined by using a device for horizontal positioning of the column.

First, a column horizontal positioning device according to the present invention will be described.

FIG. 1 is a perspective view of a column horizontal positioning device according to the present invention. FIG. 2 is a view occupying the pedestal of the column horizontal positioning device. FIG. 3 is a view showing a state where the horizontal positioning device for the pillar is assembled.

As shown in FIGS. 1 to 3, the column horizontal positioning device of the present invention includes a pedestal 1 and a gauge member 2 slidably mounted on the pedestal. Pedestal 1 is top plate 3
And two leg members 4, 5 hanging from the top plate 3, and
And a tightening bolt 7 mounted in a bolt mounting hole 6 provided in one leg member 4. Also, on the top plate 3,
A long hole 8 is drilled in the center of the hole. This is because when the gauge plate is slid on the top plate, the shaft of the bolt 9 for fixing the gauge plate and the top plate is elongated in the top plate. It is provided so that it can move freely inside. The gauge member 2 is provided with a leg portion 14 of a gauge plate bent downward on both sides thereof, and the gauge member is arranged on the top plate so as to straddle the top plate 3. The provision of the legs 14 prevents the lateral displacement of the gauge material. Note that the gauge material can be provided so as to hold the top plate. In order to fix the gauge member 2 to the top plate 3, the bolt 9 inserted into the bolt mounting hole 17 can be fixed by tightening with a nut 10, but other fixing tools may be used.

Next, a description will be given of a method of positioning a steel pipe column inserted into a steel pipe pile using the horizontal positioning device of the present invention.

FIG. 5 is a view showing a state in which a horizontal positioning device is attached to a steel pipe pile and a column is inserted into the steel pipe pile.

As shown in FIG. 5, a horizontal positioning device in which a gauge member 2 is mounted on a pedestal 1 is installed on the head of a steel pipe pile installed on a foundation concrete. That is, the upper end of the steel pipe pile head is fitted into the recess between the leg members 4 and 5 of the pedestal 1. When the bolts attached to the leg member 4 at two locations are tightened, the bolt tip 11 presses the outer surface of the steel pipe pile head. As a result, the steel pipe pile head is fastened by the leg member 5 and the bolt tip 11, and the pedestal 1 can be fixed to the steel pipe pile head. In order to firmly attach the pedestal to the steel pipe pile head, it is preferable to provide at least two fastening bolts.

The horizontal positioning device must be installed at at least two places on the head of the steel pipe pile because the horizontal position of the pillar must be determined on both sides of the pillar in the steel pipe pile. In the case of two locations, it is desirable to provide the circumference of the steel pipe pile in two divided positions, and in the case of providing three locations, it is desirable to provide the circumference of the steel pipe pile in three parts. In the case where four or more locations are provided, the circumference of the steel pipe pile may be similarly set to a divided position. However, it is not practical to install too many, and two to four locations are desirable.

After mounting the pedestal 1 on the head of the steel pipe pile, the erection position of the column is measured, and the gage member 2 is positioned so that the tip position of the gage material matches the measured outer surface position at the erection position of the column. The gauge material is slid on the top plate 3 to perform positioning.

That is, the position of the gauge member 2 is adjusted so that the gauge member 2 of each positioning device provided at the head of the steel pipe pile can contact the outer surface of the column at a predetermined position.

After adjusting the position of the gauge material, the bolt 9
And the nut 10 to tighten the gauge material 2 to the top plate 3 of the base 1.
Fixed to

The column is installed by suspending the column, inserting the column into a steel pipe pile, and adjusting the position of the column so that the column contacts the gauge member 2.

Thus, since the tip of the gauge material becomes the outer surface of the installation position of the column, the installation position of the column in the horizontal direction can be determined. After hanging the column and inserting it into the pile and holding it at the installation position in contact with the gauge tip, for example, insert a fixture such as a wedge into the gap between the column and the steel pipe pile, fix the column by wedge action, and fix the concrete. If it is cast, the standing pillar is completed.

Further, when inserting the column into the steel pipe pile, the column collides with the gauge member 2, and it may take time to insert the column. Therefore, in the present invention, when the guide member 12 is provided on the gauge member 2 and the column is inserted, the column is guided by the guide member 12 so that the column does not collide with the gauge member 2.

FIG. 4 is a view showing a state in which a guide plate is provided as a guide member for guiding the column to the gauge member.

As shown in FIG. 4, the guide member 12 extends upward from the end of the gauge member 2 and its upper portion is bent (rightwardly bent in FIG. 4) to serve as a column guide. It has become.

Further, in order to reduce the friction between the column and the guide member, a member such as a roller for reducing friction can be embedded in the guide member so that the column can move smoothly on the surface of the guide member. Further, in order to prevent deformation of the guide member, a reinforcing member 13 connecting the guide member 12 and the gauge member 2 may be provided. And, as the guide material, a plate-like or rod-like material can be used.

[0031]

According to the present invention, the installation position of the column in the horizontal direction is adjusted at the head of the steel pipe pile, so that there is no need for a person to work inside the pile and workability is improved. Moreover, since the operation of a person inside the pile is eliminated, it is not necessary to increase the pile diameter more than necessary. In addition, since the slide mechanism is provided on the pedestal and the gauge material, it is possible to easily absorb the construction error of the arbitrarily generated pile, and it is possible to carry out the work in a uniform manner, so that the workability is good. .
