Description of the Related Art The applicant of the present application has proposed that a pile be used as a pillar as it is as a building structure suitable for low-rise stores and warehouses and capable of significantly reducing building costs (Japanese Patent Application No. 8-275116). In the building structure using this pile as a pillar, the construction time is greatly shortened and the construction cost is reduced because the foundation footing and the underground beam are not required. On the other hand, it is a prerequisite for building structures to have the required strength against earthquakes, etc., so the surface layer of the site ground was improved. This is based on the following analysis results.

000 mm, the length L P of the wire L corresponding to the pile buried in the ground is 9000 mm, and the length L C corresponding to the pillar erected on the ground is 9000 mm. It was 4000 mm. The tip of該線material L (the lower end) as well as pin support, as in the portion L P corresponding to the pile portion corresponding to the elastic restoring force receiving pilings from the ground, a total of nine spring k 1, k the 2 ... k 9 are connected horizontally at 1000mm intervals. An axial force P is applied to the top end of the wire L as an external force.
And a horizontal force H was applied.

That is, when the spring constants of these springs k 1 , k 2 ... K 9 are set to various sizes, and how the deformation mode of the wire L changes is examined, the spring constant of the spring k 1 changes. And the deformation mode of the wire L also greatly changes, but only by changing the spring constants of the other springs k 2 to k 9, no significant change was found in the deformation mode of the wire L.

This makes the evaluation of the whole system extremely easy. That is, in case of applying the present analytical model to the specific construction site defines a spring constant of each depth by boring the site soil, it the spring constant of the spring k 1, k 2 ... k 9 Although this will be applied, it is difficult to obtain an accurate value because the boring data has large variations. However, what is required accuracy is only the spring constant of the spring k 1 of the surface layer, it the spring constant of the deeper somewhat may lack accuracy. Therefore, the surface layer if to ground improvement, the ground characteristics artificially can operate, therefore, it is possible to accurately calculate the spring constant of the spring k 1. Thus, highly reliable evaluation is possible, and the required strength of this type of building structure can be sufficiently ensured. Depending on the ground conditions,
In some cases, it may not be necessary to improve the ground.

の接続方法。1. Piles comprising an underground pile and a ground pillar
Function as a pillar material, and
Piles with concrete on the ground floor on the first floor are used as pillars
Building structure, wherein the pile pillars are made of PC steel on the inner peripheral surface.
Insert the reinforced cage into the formwork and compact by centrifugal compaction
And a pile cap is disposed at the top end of the pile post.
At the same time, a cylindrical steel material is disposed at a predetermined position of the pile post,
Connecting a steel column to a steel member to connect a pile column and a steel frame
In the method, the building structure remediates a surface layer of the ground.
To eliminate the need for underground beams and foundation footings, while the centrifugal compaction of the
The pile cap and the pile post
A plurality of vertical streaks are arranged between the cylindrical steel material to be installed, and
The upper end of the vertical streak contacts the inner peripheral surface of the pile cap.
And weld the lower end of the longitudinal bar to the inside of the cylindrical steel material.
Abutting on the peripheral surface and welding;
Extrapolate the cylindrical steel material by the side and insert the iron
By inserting a reinforcing rod, the pile is attached to the top edge of the reinforcing rod.
The cap is crowned and the rebar basket is inserted into the formwork
When forming pile columns by normal centrifugal compaction
The tubular steel is formed so as to be exposed on the outer surface near the top of the pillar.
Is, after Kenkomi the該杭column using該杭pillar, in pile pillars in a building structure utilizing the pile, characterized in that to connect the steel member to the column directly or through a copy to the cylindrical steel and Connection method with steel members.
