[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame binding structure and a frame binding structure, and in particular, a bolt member protruding upward from a horizontal frame member and a hole-down fitting attached to a vertical member installed above a joist. Then, the present invention relates to a frame binding material and a frame binding structure used for tightly fixing the vertical member.

[0002]

[Prior Art and Problems to be Solved by the Invention] The framed wall construction method was introduced to Japan by the platform construction method, which is the most common wooden house construction method in North America. It uses complicated joints and joints for the joining method. Unlike conventional construction methods, there are few types of cross-sectional dimensions of the wood that composes the building, and basically the building is constructed by nailing construction. In other words, it is a method of constructing a building with floors and walls in which structural plywood is nailed to a frame made up of dimension lumber.

More specifically, as shown in FIG. 5, a base 51 is provided on a cloth foundation 50, joists 52 and 53 are arranged side by side to form a floor set, and a plywood 54 is pasted on the floor (platform). The attachment work of the vertical frame 55 is performed. In addition, in order to build a building on the upper floor part, a head joint 57 is provided on the upper frame 56 attached to the upper end of the vertical frame 55, and joists 52, 53 are provided.
Are arranged to form a floor set, a plywood 54 is attached, and the vertical frame 55 of the upper floor portion is attached on this floor.

In such a framed wall construction method, anchor bolts and other bolt members which are fastened to hole down fittings attached to vertical members such as vertical frames and columns are tightly fixed, and the cores of the vertical members are the cores of the vertical members. Often arranged along the. On the other hand, for example, joists located below the bearing wall in the middle part of the building may be arranged along the center line of the module.In such a case, the axial center of the anchor bolt and the core of the joists are Since they coincide with each other, a method has been adopted in which the anchor bolt is installed by penetrating the joist, or the joist is cut and divided and attached at a position where the anchor bolt projects.

However, the method of penetrating the anchor bolts or cutting and dividing the joists takes time and labor, and particularly when prefabricating a building, there is a problem that efficient construction cannot be performed. In addition, a bolt member such as a long anchor bolt that extends from the horizontal frame member such as the foundation or head tie on which the joist is placed to above the joist is difficult to obtain the positional accuracy, and when the inclination accuracy is poor, the floor member is difficult. There was a problem that the construction was difficult, such as the position of the holes provided in the building did not match.

The present invention has been made in view of such conventional problems, and does not need to provide a bolt member penetrating a joist and to increase the length of the bolt member.
An object of the present invention is to provide a frame-bonded metal product and a frame-bonded structure capable of easily fastening a bolt member to a hole-down metal product attached to a vertical member.

In the center of the lower end portions of the pair of side surface portions 24, first integrated bolt holes 25 each having a size of about φ13 are formed at positions where they coincide with each other, and the upper metal fitting 20 is provided with a joist 13 above the bolt holes 25. Hole 30 for temporary fixing to
Are provided in two places each. Where the upper hardware 2
Since 0 has a U-shape that sandwiches the joist 13 from both sides, it has a structure sufficient to increase its rigidity and to support the pulling force via the connecting bolt 19.

Further, the vertical plate portion 27 which constitutes the lower metal member 22 is formed by partially overlapping a pair of symmetrical hook-shaped pieces 31 made of steel plates having a thickness of about 3 mm. The bottom part of the joist 13 has a rectangular shape with a length of about 90 mm and a width of about 100 mm, and has a length of about 50 mm and a width of about 55 mm at the center of the lower half. A rectangular fastening opening 28 having a size matching the cutout opening 35 formed in the edge portion is formed. The pair of hook-shaped pieces 31
They are overlapped with each other with a width of about 40 mm above the fastening opening 28, and a second integrated bolt hole 29 with a size of about φ13 is formed at the center of this overlapped portion. Since the second integrated bolt hole 29 is formed in the overlapping portion, as described later, when the upper metal piece 20 and the lower metal piece 22 are integrated with each other through the integrated bolt 32, a strong integration is achieved. Can be structured. A pair of nail holes 33 for temporarily fixing the lower metal member 22 to the joist 13 are provided on both sides of the second integrated bolt hole 29, outside the overlapping portion.

The base plate portion 26 constituting the lower metal member 22 is made of a steel plate having a thickness of about 3 mm, has a rectangular shape with a width of about 50 mm and a length of about 60 mm, and has a vertical plate portion 27. A fastening hole 21 having a size of about φ30 is formed in the central portion close to. The base plate portion 26 has a reinforcing plate 34 which is welded to both side edges of the base plate portion 26 and vertically fixed.
As a result, each of the rear side edges of the reinforcing plate 34 that is vertically erected while having a U-shaped cross section
The base plate portion 26 extends vertically with respect to the vertical plate portion 27 and is firmly fixed by welding to both side edges of the fastening opening 28 of No. 7.

The lower metal piece 22 is shown in FIG.
As shown in (c), the base plate portion 26 is inserted into the cutout opening 35 provided in the lower end edge portion of the joist 13, and the U-shaped plate 36 of the upper metal fitting 20 previously attached to the joist 13 is inserted. The vertical plate portion 27 is arranged along the one side surface portion 24, and is disposed below the upper metal member 20. As a result, the first integrated bolt hole 25 and the second integrated bolt hole 29 are aligned with each other, and the upper bolt 20 and the lower bolt 22 can be integrated by inserting and fastening the integrated bolt 32. Become.

Here, the anchor bolt 15 projects from the base 12 at a notch opening 35 formed at the lower end edge of the joist 13 at the projecting portion of the anchor bolt 15, and above the notch opening 35. The bolt insertion hole 37 for inserting the integrated bolt 32 is formed in the joist 13 in advance (FIG. 3).
(See (a)).

Therefore, the base plate portion 2 is made to match the fastening opening 28 of the lower metal piece 22 with the cutout opening 35.
6 is inserted and arranged in the notch opening 35, and the anchor bolt 1
5 is fastened to the fastening hole 21 of the base plate portion 26, and the upper metal fitting 20 is provided so as to cover the upper end surface of the joist 13.
