Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column-pile joining member for a steel structure.

[0002]

2. Description of the Related Art Conventionally, when constructing a foundation beam for a steel structure, piles are generally arranged in a hole excavated in the ground (hereinafter referred to as a foundation hole). Then, a groove (hereinafter referred to as a foundation beam groove) that communicates with both foundation holes is excavated between adjacent foundation holes, a wooden frame and a reinforcing bar are arranged in the foundation beam groove, and concrete is placed to form the foundation beam. It is provided (prior art 1).

Further, for example, in Japanese Examined Patent Publication No. 3-51428, spacers are preliminarily provided around the entire inner surface of a predetermined section from the top end of a pile steel pipe erected in the ground, and filled concrete is poured into the pile steel pipe. After the hardening of the filled concrete, the concrete and spacers in the predetermined section are removed, and the pillar steel frame is inserted into the pile steel pipe, and then the concrete is filled into the space between the joints of the pile steel pipe and the column steel frame. An invention relating to a method for constructing a pile joint is disclosed (prior art 2).

[0004]

In the construction method of the prior art 1, in order to construct a foundation beam, in addition to the outer shape of the wooden frame, a large foundation beam groove on which the worker can work is excavated. Most of the huge amount of excavated earth and sand has to be carried out to the outside, discarded, and then concrete must be placed, which requires a large number of man-hours and a large amount of money, which causes a problem such as a long construction period. The workability was poor. Also,
Since the foundation and foundation beams are concrete and the upper structure joined to them is a steel pipe column (steel frame column), there is also a problem that the design concept is not unified.

Further, in the construction method of the prior art 2, since the pile steel pipe is used for the foundation, there are problems such as excavation of the foundation hole, installation of a wooden frame and the like, inconsistent design concept as in the above prior art 1. Although it does not occur, the concrete and spacer at the part where the pillar steel frame is inserted must be removed after concrete is cast into the pile steel pipe and hardened, and the pillar steel frame is inserted directly into the pile steel pipe and joined. Therefore, it is extremely troublesome to adjust the vertical and horizontal positions of the column steel frame, which requires a lot of man-hours and costs, and the construction period is unavoidable. In addition, when the foundation beam is provided between the adjacent pile steel pipes, the same problem as in the case of the conventional technique 1 occurs.

The present invention has been made in order to solve the above-mentioned problems. It does not require the placing of concrete for foundation beams, and the positional accuracy of column joints is high. Therefore, the number of man-hours and costs are reduced, and the construction period is shortened. The purpose is to obtain a column-beam joint structure with excellent workability.
