JPS587785B2 - Frame members with joints - Google Patents

Description

[Detailed Description of the Invention] The present application relates to a frame member having a joint part that is useful for connecting the tops and even corners of frames or for connecting frames. This invention relates to a frame member having a joint portion and forming a cylindrical body.

Traditionally, Shiguchi was joined using various joint plates, corner parts, etc., but especially at angled joints such as the top of a mountain frame and even corners, it was necessary to create a certain slope. The selection of joining members and the joining work are extremely complicated.

The present application was developed in view of the above-mentioned circumstances, and is designed so that the joint parts of the plurality of frames to be joined form a cylindrical body.
A cylindrical joint with a half-sided or fan-shaped cross section is provided at the end of each frame to improve workability and to make it more versatile.

The frame member according to the present application will be described in detail below.The structure is such that bolt holes 3 are bored in a plane 1b forming the circumferential surface of a cylindrical joint 1 having a semicircular or fan-shaped cross section, and the circumferential curved surface of the joint is It is characterized in that the end portion of a square pipe-shaped frame member 2 is bonded and fixed to 1a.

In practice, each member is often joined by bolting or riveting, so bolt holes 3 are bored in the plane 1b forming the peripheral surface of the joint 1.

Further, the slope of the frame member 2 is preferably a rectangular pipe or other shaped steel that can be moved on the circumferential curved surface 1a of the joint portion 1 by slidingly contacting the end of the frame.

The drawings show a preferred embodiment of the present application, and Fig. 1 shows a slope view and a vertical cross-sectional view of a joint portion 1, which is the main part, and Fig. 2 shows a top and an uneven view of a chevron rigid-frame structure using the present application. This is a diagram showing a corner joint. The joint 1 in this case is a short tube with a semicircular cross section as in FIG. 1, and a curved surface 1a is welded to a flat surface 1b. 1, the mutual orientation is determined and welded at the stage of materials before assembly.

FIG. 3 shows another embodiment of the present application, in which three members 2
The joint part 1 has a fan-shaped cross section so that the parts can be joined.

In addition, the present invention may be used as a joint between two members as shown in FIG. 4, or as a pillar base as shown in FIG. 5.

Further, in the present application, reinforcing means such as ribs may be provided on the joint portion 1 as necessary.

In the above-mentioned drawing example, 11 is a bolt for fixing the joint, 12 is a metal fitting for connecting to a column, 13 is a base plate, and 14 is an anchor bolt.

The structure of the frame member according to the present application is as described above,
Its structure provides the following unique effects.

Each joint part of a plurality of frame members 2 to be joined can have sufficient strength, since each joint part 1 composes a cylindrical body with partitions, and can also be resistant to vibration. It has a unique effect, such as being able to create relief with its cylindrical body.

When the frame member 2 is joined to the joint part 1, it can be made to form an arbitrary angle within 90 degrees with respect to the joint part 1 by slidingly moving on the peripheral curved surface 1a of the joint part 1. It can be used as a joint between parts with arbitrary angles such as even corners, it can also be used as a joint by aligning the axial directions of two frame members, and the joint part 1 can be used as a column base. You can also do it.

Particularly when used as a column base, it has the effect of reducing the pitch of anchor bolts and reducing the base area.

The joining of the joint parts 1 of each frame member is extremely easy because the two thousands faces 1b, which are the partition plates in the cylindrical body formed by combining the joint parts, are joined by bolting, and the work is extremely easy. Since the part to be tightened is always inside the cylindrical body, problems such as being hidden by other structural members and not being able to be worked on are eliminated.
