Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for joining materials used for steel pipe piles.

[0002]

2. Description of the Related Art As shown in FIG. 3, when a structure under a track is to be constructed by an open-cutting method, a track is temporarily received by a construction girder 1, a receiving girder 2, and a steel pipe pile 3, and the under-track is cut and cut under the track. A method of constructing the structure 4 is conceivable. In this construction method, it is necessary to connect the steel pipe piles with the joint member 5 as shown in FIG.
For this purpose, the joining material 5 is joined to the joining material connection 6 formed in the steel pipe pile.

FIG. 5 is a view for explaining a conventional joint for joining materials.
FIG. 5A is a front view, and FIG. 5B is an AA cross-sectional view. In the drawings, the portion described as a welded portion indicates an in-situ welded portion as indicated by Note). The joint 6 for joining material is attached by welding a horizontal ring stiffener 7 and a vertical ring stiffener 8 cut at a factory to a steel pipe pile at the site. (Not shown) and joining the joining materials by bolting or the like.

[0004]

However, since the conventional joint for joining material is formed on a steel pipe pile by on-site welding, the cost is higher than that of factory welding, it takes more time for construction, and the quality is inferior. There was a problem. An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a joint for a joint material to be attached to a steel pipe pile, which can improve economy, workability, and quality.

[0005]

According to the present invention, a horizontal ring stiffener, a vertical stiffener, and an end plate are attached to a steel plate bent at an inner radius equal to the outer radius of a steel pipe pile by factory welding. Features. The invention of claim 2 is characterized in that the two joints for joining materials are sandwiched from both sides of the steel pipe pile, and the end plates are joined to each other by high-strength bolts so as to adhere to the steel pipe pile.

[0006]

Embodiments of the present invention will be described below. FIG. 1 is a view for explaining a joint for joining material of the present invention.
1 (a) is a front view, FIG. 1 (b) is a sectional view taken along line AA of FIG. 1 (a), and FIG. 2 is a perspective view for explaining a joint for joining material.
The locations marked as welds are factory welds. The joint for joining material 10 is factory-welded with a horizontal ring stiffener 12 at the upper and lower parts of a steel plate 11 bent at an inner radius equal to the outer radius of the steel pipe pile 3 to form a joint 12a between the horizontal ring stiffener 12 and the joining material. The vertical stiffener 13 is factory-welded to the end plate 1 at the end of the steel plate 11.
4 is manufactured by factory welding.

[0007] The two joints for joining materials thus manufactured are attached so as to be sandwiched from both sides of the steel pipe pile 3 at the construction site (FIGS. 1A and 1B), and the end plates 14 are connected to each other by high-strength bolts 15. Join. Accordingly, the steel plate 11 and the steel pipe pile 3 bent at an inner radius equal to the outer radius of the steel pipe pile 3 come into close contact with each other. The joining material is joined to the joining material joint 10 thus attached in the same manner as in the related art. Since a special vertical load is not applied to the joint, the steel plate 11 and the steel pipe pile function sufficiently only by being brought into close contact with each other, and the stress generated in the steel pipe pile can be reliably transmitted to the joint.

[0008]

As described above, by attaching the joint for joining material of the present invention to a steel pipe pile, it has a function similar to that of the case where it is attached by on-site welding, and ensures that the stress generated in the steel pipe pile is applied to the joint material. Can be transmitted to And since the joint for joining materials is manufactured by factory welding, it can be attached to the steel pipe with high-strength bolts at the construction site, and there is no need to perform on-site welding. Therefore, it is possible to improve the economic efficiency, the workability, and the quality as compared with the conventional joint for joining materials attached by field welding.
