Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a joining device for members applied to joining parts of columns and beams in a wooden structure.

(Prior Art) Conventionally, a joint portion between a pillar (a) and a beam (b) in a wooden structure is, as shown in (i) FIG. 6, a strip metal object (c) that is bridged between the pillar and the beam. , The same hardware and columns and beams are joined by bolts (d) that are tightened, or (ii) as shown in FIG. 7, the flat plate portion of the battledore bolt (e) that is tightened and inserted into the pillar (a). Tighten the beam (b) and the bolt (f), or (iii)
As shown in FIG. 8, both sides of the column and the beam are sandwiched by the iron plate (g) and joined by nails or bolts (h).

(Problems to be solved by the invention) However, in the joint structure of (i) and (ii), since there is a gap between the bolt and the bolt hole formed in the member, the relative displacement of the joint portion is large. However, there was rattling, and the joining strength was insufficient.

Further, in the joint structure of (iii), the added iron plates were exposed on both side surfaces of the column and the beam, which was inconvenient in terms of finish and appearance.

The present invention has been proposed in view of the above problems of the prior art, and a purpose thereof is to configure a moment resistance joint portion which is close to a rigid joint without causing rattling in the member joint portion. In addition, a joining device is provided for a member in a wooden structure that does not impair the appearance.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a joining device for members in a wooden structure according to the present invention has a structure in which one member among the wooden members to be joined at an angle intersects each other. A pair of parallel bolt embedding holes that extend in the material axis direction of the one member and that are open at the joint end face of the other member whose end portion intersects with the same member are provided in the other member, and A pair of bolt through-holes extending in the extension direction of the material axis of one member are provided in parallel with each other, and while each pair of bolt through-holes and the one or more bolt embedding holes are respectively inserted with one pair of bolts, An adhesive is filled in the gaps between the bolts and the inner peripheral surfaces of the bolt through holes and the bolt embedding holes.

(Operation) As described above, according to the present invention, among the wooden members to be joined that intersect at an angle to each other, the one member provided on one member extends in the axial direction of the member and the end portion is A pair of parallel bolt embedding holes that open in the joint end surface for the other member that intersects the same member, and mutually parallel bolt penetrations provided in the extension direction of the material axis of the one member in the other member. By inserting the bolts through the holes, the bolts are arranged in the both members, and the adhesive is provided in the gap between the bolts and the inner surfaces of the bolt embedding holes and the bolt through holes. And the bolts are integrally fixed in the holes, and thus embedded in the members, a pair of bolts parallel to each other are provided so that the compression axis of the bolts is against the bending moment in the vertical plane of the members. Resists by force and tensile axial force By doing so, a moment resistance joint close to a rigid joint is formed.

(Embodiment) The present invention will be described below with reference to the illustrated embodiment.

In FIG. 1, (A) is a wooden column, (B) and (B ') are wooden beams horizontally arranged on both sides of the column (A), and the beams (B) and (B') are the same.

Further, the pillar (A) extends vertically on the same axis as the pair of upper and lower bolt embedding holes (1) (1 ') of the respective beams (B) and (B') and penetrates the same pillar (A). A pair of bolt through holes (3) are provided.

When the pillar (A) and the beams (B) and (B ') are joined, a pair of upper and lower bolt through holes (3) of the pillar (A) and upper and lower pairs of the beams (B) and (B') are joined. Bolt embedding hole (1)
A bolt (4) is inserted over (1 '), and water-proof packing materials (5) and (5') are installed so as not to generate voids at the periphery of the joint surface of the column and beam, and the adhesive injection Entrance (2)
An adhesive such as an epoxy resin adhesive is injected from (2 '), and the adhesive is filled over the bolt embedding holes (1) (1') and the bolt through holes (3). Each hole (1)
(1 ') An adhesive is filled in the gap between the inner peripheral surface of (3) and a pair of upper and lower bolts (4), and the bolts (4) and pillars (A), beams (B) and (B') Unify.

At this time, the water-proof packing material (5) (5 ') prevents the adhesive from leaking from the column-beam joint surface.

Therefore, it is buried in the pillar (A) and the beams (B) (B '),
The upper and lower bolts (A) integrated with the same pillar and beam resist the bending moment in the vertical plane of the beam by the compressive force of one bolt and the tensile force of the other bolt, and thus rigid connection is achieved. A moment resistance junction close to is constructed.

In the above-mentioned embodiment, the case where the beams are arranged on both sides of the column is shown, but the present invention is also applied to the case where the beams are arranged on one side of the column or in three directions.

FIG. 2 shows another embodiment of the present invention, in which a part of the bolt (4) is inserted into each of a pair of upper and lower bolt embedding holes (1) provided in the beam (B), and the embedding hole (1) is formed. ) Is filled and fixed with an adhesive, and bolts (4) protruding from the joint end face of the beam (B)
