[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural laminated member with a joint fitting that facilitates connection when a structural laminated member is used for a pillar, a beam, a girder, etc. in construction.

[0002]

2. Description of the Related Art There are various methods for connecting structural laminated wood. A flange plate type in which the upper and lower surfaces of the laminated wood are sandwiched by plates, and the upper and lower surfaces of the laminated wood are sandwiched by plates. In addition to the flange plate lag screw type that is fixed with a lag screw and the wegg plate type that clamps bolts at several side surfaces of the laminated wood with plates, Japanese Patent Application No. Sho 63-133766 and Japanese Patent Application No. 2-9059.

[Problems to be Solved by the Invention] However, although the connection is made by such a method, in the former case, since the work is performed on site, the larger the beam or the like, the more labor is required for the connection work, and much labor is required. And in the latter case,
Although the number of on-site works was small, it was limited to only the connections between the same beams including the former, and it was difficult to connect to other columns and girders, which made me feel very inconvenient for construction.

[0004]

[Means for Solving the Problems] The present invention solves such a problem and provides a laminated member with a joint metal fitting which can be easily connected not only to the same beam but also to a column or a girder through a joint metal fitting. It is something to do. In other words, a fastener made by fixing a suitable number of mounting plates with screw holes to a connecting rod made of deformed reinforcing bars or bolts is used as an end face suitable for the laminated member used for beams, girders, columns, etc. at an arbitrary angle. The connecting rod is embedded so that it protrudes in an appropriate amount at a place or in a concave portion where a concave portion is drilled, fixed with an embedded mounting plate and an adhesive, and a supporting plate is projected on a joint metal object of any shape with a polygonal cylinder, and a fixing plate. This is a combination of the installed concave coupler and a joint metal fitting such as a joint coupler composed of a convex coupler.

[0005]

[Operation] Select a metal fitting suitable for the joining location on the end face of the laminated lumber to be joined. For example, if the laminated lumber is used as a beam or column, combine it with a joint metal fitting, or in the case of a ridge, use a recess It is used by combining the laminated laminated material and the joint coupler, which are fixed and joined with the connecting rod and the nut.

Fixing with connecting rod 3 and nut 6, supporting plates 7b, 8
b is connected by the pin 9a and the laminated member 4 is joined.

(2) For joining eaves or ridges using the laminated lumber 4 as pillars, beams or girders, (a) For joining eaves or ridges as shown in FIG. The end surface 4a of the laminated member 4 is applied to the end portion 10a of the joint metal fitting 10, and the connecting rod 3 and the nut 6 are attached.
The laminated members 4 which are connected to each other as a beam or a pillar are joined. (B) In the case of joining a column and a girder as shown in FIG. 5, the end face 4a of the laminated member 4 which is a column using the joint metal 5
The end surface 4a of the laminated lumber 4 which is made into a girder is applied to the joint metal 5, and the connecting rod 3 and the nut 6 are connected to join the laminated lumber 4. (3) For joining when a large number of laminated members 4 are gathered as beams, as shown in FIG. 8 , joint hardware 11 made of a trapezoidal cylindrical body is radially provided on the column 12, and the end face 4a of the laminated member 4 is formed.
Is applied to the bottom surface 11a of the joint metal 11, and is connected by connecting the connecting rod 3 and the nut 6.

(Second Embodiment) Since this embodiment is almost the same as the first embodiment, only different parts will be described. Reference numeral 13 denotes a laminated member having an arbitrary cross section,
A mounting plate 2 in which a concave portion 13b having a proper depth is formed in a proper position in a, and the fastener 1 is embedded so that the connecting rod 3 projects into the concave portion 13b.
It is fixed with adhesive X. Fig. 9
The concave coupler 7 of the joint coupler 9 is fixed to the concave portion 13b of the one laminated member 13 and the convex coupler 8 is fixed to the concave portion 13b of the other laminated member 13 by the connecting rod 3 and the nut 6 as shown in FIG. The concave coupler 7 and the convex coupler 8 are connected and joined. In this case, the joint coupler 9 is built in by the recess 13b, and the end face 13a is brought into close contact.

It is fixed to the attached mounting plate 2 with an adhesive agent X. In use, as shown in FIG. 10, it is used at the ridge or eaves, and the method is the same as that of the second embodiment, so the explanation is omitted.

[0011]

As described above, according to the present invention, since the fastener having the mounting plate embedded in the laminated member is provided so as to project and is combined with the joint metal fitting, the laminated member is used for the beam, girder or column. When joining, it can be done by selecting so as to adapt to each joining position, and the joining is simple and anyone can do it securely, and the fastening plate is fixed firmly with the mounting plate and the adhesive. It has many features such as strong and is a very excellent idea in practice.
