Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intersection joining joint for a wooden construction and a method for joining an intersection joining a wooden construction by using the joint.

[0002]

2. Description of the Related Art For example, a total of four horizontal beams such as beams and body differences are attached to a through-column so as to have a substantially uniform installation height in a cruciform cross-shape in a plan view. A utility model registration No. 2599759 is known as a joint joint for assembling a T-shaped crossover type in a plan view with a mounting height of a bridge to a through column as a whole. Case One long bolt (102) that penetrates the pillar (100) and its fixing nut (1
It can be said that the present invention is similar to the present invention in that 03) is used.

[0003]

However, since the joint joint (main member) (10) of the above-mentioned known device is a metal product bent in a U-shape in plan view, it is easy to pack and transport it to the construction site. Also, it is very heavy in handling at the construction site,
Not only is it bulky, but also when it is mounted on the pillar (100), unless a special dedicated turning operation tool is inserted into the frame of the joint (10), the nut (103) is not attached to the bolt (102). It is still annoying and inconvenient because it cannot be fixed by tightening.

Further, a large number of bolt holes (12) are distributed in the back portion (11) of the joint (10), and as shown in FIGS. 3 and 7, the bolt holes (12) are removed. The bolts (102) that penetrate the pillar (100) in an orthogonal state are selectively released so that they do not interfere with each other.

Therefore, when inserting the joint (10) into the bolt (102) and selecting the bolt hole (12) easily, it is easy to misunderstand, and moreover, the joint (10) itself must be upsized. Therefore, it is difficult to apply it to thin horizontal materials.

[0006] In order to prevent the joint joint (10) from unsightly protruding from the horizontal member such as the beam (200), the body difference, and the girder, the size and the bolt hole corresponding to the change in the thickness of the horizontal member. It is necessary to prepare a large number of different types of bonded joints (10) with different numbers in advance and prepare them in stock, or to use them properly, which is inferior in mass production effect and versatility.

In this case, a so-called plug that can be tapped with a hammer or the like may be used as each of the fixing pins (P), but in particular, a rotating operation tool (16) as shown in FIGS. Therefore, it is desirable to adopt a form that is screwed into the fixing pin receiving communication holes (15) (15) of the horizontal member (X).

That is, in the fixed pin (P) shown in FIGS. 18 and 19, the cylindrical pin body (1) made of a metal pipe material is used.
