Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure for a horizontal member and a metal fitting for the horizontal member, which is used when joining a column and a horizontal member such as a beam or a girder.

[0002]

2. Description of the Related Art Conventionally, when a column and a beam, girder, or the like are joined together, a protrusion formed at one end of the beam or girder is fitted into a recess formed on the column side to join them together. Or by using an L-shaped metal joining metal fitting as an auxiliary, and further by fastening the pillar and beam with bolts and nuts. on the other hand,
In recent years, in order to reduce the work at the construction site, the so-called pre-cutting method, in which the shapes of pillars, beams and other members are cut in advance in a factory, has been actively carried out. Therefore, it is often the case that the metal fittings used to join the pillars and beams are fixed to the pillars or beams in advance and transported to the construction site in this state.

By the way, as for such a metal joint metal, there is one proposed in, for example, Japanese Patent Application Laid-Open No. 10-25812. As shown in FIG. 5 , the metal joint 100 has a bolt 101 and a nut 1 on the side surface of the pillar P.
02 (and washers 103 and 104), and the beam H is joined by the joining metal piece 100. The joining hardware 100 is fixed to the pillar P, a fixing plate portion 105, a left standing plate portion 106 that stands upright from the left side of the fixing plate portion 105, and a left standing plate portion 106. A right standing plate portion 107 which stands upright from the right side of the fixed plate portion 105, a left end thereof is continuous with the left standing plate portion 106, a right end thereof is continuous with the right standing plate portion 107, and a rear end thereof is Fixed plate part 105
And a bottom plate portion 108 that is continuous with. The left standing plate portion 106 and the right standing plate portion 107 are formed with locking grooves 106a, 107a at the upper ends thereof, and insertion holes 106b, 10 through which bolts are inserted, respectively.
7b is provided.

On the other hand, at one end of the beam H, the left side groove portion H ₁ into which the left side upright plate portion 106 is inserted and the right side upright plate portion 10 are provided.
A left-side groove portion H ₂ into which 7 is inserted is formed, and the left-side groove portion H ₂ is formed.
₁ and the left-side groove portion H ₂ between the above-mentioned joining hardware 100 and the pillar P.
The head portion of the bolt 101 used for fixing to is cut by the thickness length. Also, on the upper end side of this beam H,
A locking bolt 109 is fixed in the thickness direction of the beam H, and the insertion hole 10 is provided below the locking bolt 109.
Bolt insertion holes H ₃ are formed at positions corresponding to 6b and 107b. Therefore, the joining structure of the beam H to the pillar P by the joining hardware 100 is the same as the above-mentioned locking bolt 1
Both ends of 09 are locked in locking grooves 106a, 107a formed at the upper ends of the left standing plate portion 106 and the right standing plate portion 107, and the joint metal 100 and the beam H are joined together by the joint bolt 1
It is fixed by 10,111.

[0005]

However, in the structure in which the pillar P and the beam H are joined by the above-mentioned conventional joining metal fitting 100, the joining fitting 100 is fixed in advance in a factory and transported to the construction site. Considering this, it is bulky and cannot transport a large number of columns P at one time. In particular, FIG.
As shown in FIG.
2 or 3 metal fittings 10
When 0 is fixed, the efficiency is extremely low in consideration of the transportation work. Further, in the above-described conventional joining hardware 100, the left standing plate portion 106 and the right standing plate portion 10 are provided on both the left and right sides.
Since 7 is formed, the work of fixing the fixing plate portion 105 to the pillar P is also inefficient.

Therefore, the present invention has been proposed to solve the problems of the above-described conventional metal joint, and even when it is fixed to a column in advance, it does not become bulky and can be used for carrying work. It is an object of the present invention to provide a joint structure for a horizontal material and a metal fitting for a horizontal material that can be carried out extremely efficiently and have good workability on site.

As shown in FIG. 1 , one end of the beam H which is joined to the pillar P by the joining hardware 40 having the above-mentioned structure, as shown in FIG. 1 , is a slanted insertion groove H ₇ into which the one wire rope 43 is inserted. When insertion groove H ₈ which is inclined above the other wire rope 44 is inserted. In addition, between the insertion groove H ₇ and the insertion groove H ₈ , the fixing plate 41 is fixed to the pillar P.
The head portion of the lateral bolt 49 fixed to is cut so as not to contact. In addition, an insertion hole H ₉ is formed in the middle of one end of the beam H so that the vertical bolt 47 is inserted in the vertical direction. The aforementioned pillars P, slightly above the mounting position of the joining hardware 40, the longitudinal direction of the columnar P bolt insertion holes P ₂ is formed in a direction perpendicular, in the bolt insertion hole P ₂ On the lower side, it is parallel to the bolt insertion hole P ₂ ,
Lateral bolts 49, 49 for fixing the fixing plate 41 to the pillar P
Insertion holes P ₁ and P ₁ are formed for inserting.

[0032] FIG. 3 shows a state in which bonding the pillar P and the beam H by joining hardware 40 according to the embodiment of the implementation described above, the fixed plate 41 by a transverse bolt 49 and nut 50 It is fixed to the pillar P. In addition, the beam H, on the other hand (及
(And the other) wire rope 43 (44) is through groove H

The lower surface is supported by the upper surface and is fixed by vertical bolts 47 and nuts 51. In this embodiment, the pillar P and the beam H are further
It is fixed by the battledore bolts 54 inserted through the bolt insertion holes P ₂ . A through hole 54b into which the vertical bolt 47 is inserted is bored in a plate portion 54a constituting the battledore bolt 54, and the battledore bolt 54 is screwed to a nut 55 on the back side of the pillar P.

Therefore, according to the above-described joining fitting 40, as shown in FIG. 4 , the support plate 42 is rotated around the support shaft 46 so that the support plate 42 and the fixed plate 41 face each other. can do. Therefore, according to the joining bracket 40 according to the implementation in the form of this, the transverse bolt to the column P 4
Even when the joint fitting 40 is fixed via 9, 49, the joint fitting 40 does not largely project from the pillar P and does not become bulky. Therefore, many pillars P can be loaded and transported to the installation site. Further, with this joint fitting 40, when the beam H is joined at the installation site, the support plate 42 is simply centered around the support shaft 46 from the state shown in FIG.
The beam receiving member for supporting the beam H, like the joining metal fitting 1 according to the first embodiment and the joining metal fitting 20 according to the second embodiment, may be obtained by rotating the . 3 and the member for supporting the beam H by the central support plate 27 do not require the work of screwing a bolt and a nut (both of which are omitted in the drawings) when fixing, and workability at the installation site is further improved. It becomes possible.
