Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a beam member connector comprising a ring-shaped joint metal body for fixing a beam to be joined in a wooden construction and a wedge body for pressing the ring. .

(Prior Art) Conventionally, beams are tied together in wooden construction by gluing the beams together or by mounting a seat plate between the beams and tightening them with bolts. A concave groove is provided, and one half of the ring-shaped joining metal fitting is press-fitted into the concave groove on the one-beam side, and the other half is driven into the concave groove provided on the beam on the joining side to be fixed.

(Problems to be solved by the invention) However, in the beam joining method described above, the former is exposed to the outside such as a glazing or bolt, and the appearance is impaired. When the joint surface of the beam on the joint side is aligned with the joint surface of the embedded beam so that the positions of the recessed grooves coincide with each other, there is a problem that the one-side protruding portion of the joint metal fitting becomes an obstacle.

(Means for Solving Problems) The present invention is intended to solve these problems, and the configuration and operation thereof will be described below with reference to embodiments shown in the drawings.

From Fig. 1, a ring body with an appropriate diameter (a) and a required width (b).
A pair of prismatic pressing guide rods (3) and (3) are radially arranged at the edge of the outer peripheral surface on one side of the peripheral wall (2) so as to face the center of the ring body (1). Affixing to form the joint metal concrete (A), and separately from this, as shown in FIG. 2, the width (c) of the pressing guide rod (3).
A wedge body (B) is formed with a plate thickness equivalent to that of one side surface (4) and the other side surface is an inclined surface (5) squeezing inward.
And the wedge member (B) constitute the beam member joining device of the present invention.

Next, the operation of the present invention will be described with reference to FIGS. 3 to 6. As shown in FIG. 3, the ring body is attached to the joint surface (6) of the cross beam (T ₁ ).
For inserting a ring body having a groove width (e) slightly wider than the plate thickness (d) of (1) and a depth (f) slightly longer than the lateral width (b) of the ring body (1). A guide bar for pressing the joint metal (A) with a groove (7)
Corresponding to (3) and (3), communicate with the ring body insertion groove (7),
Opening to the outside of the cross beam (T _1), pressing the guide rod (3), (3) has a slidable width, ring body inserted from the joint surface (6) of the lateral beam (T ₁₎ Notch guide grooves (9), (9) that reach the bottom end (8) of the concave groove (7)
On the other hand, as shown in FIG. 4, the vertical beam (T ₂ ) joint surface (1
(0) is a groove (7) for inserting the ring body in the joint surface (6) of the cross beam (T ₁ ).
Corresponding to, the groove (11) for inserting and fixing the ring body having a depth of about 1/2 of the width (b) of the ring body (1) is provided, and the horizontal beam (T ₁ ) is provided as shown in FIG. In the groove (7) for inserting the ring body of the joint metal concrete (A), the guide rod (3) for pressing, the guide rods (3) and (3) from the side of (3) are cut into the guide groove (9). ), (9) while sliding, the front of the ring body (1) is flush with the joint surface (6), or is inserted with a slight depression, as shown in FIG. Joining face (6) of (T ₁ ) and vertical beam
With the joint surface (10) of (T ₂ ) being aligned with the ring body insertion concave groove (7) and the ring body insertion fixing concave groove (11) of the beams (T ₁ ) and (T ₂ ), The contact surfaces (6) and (10) come into contact with each other as if they were in pressure contact, and the guide bar for pressing
(3), the wedge guides (B), (B) in the notch guide grooves (9), (9) at the rear of each of the (3), vertical planes (4), (4) Move to the vertical beam (T ₂ ) direction by inserting into the (3) and (3) sides and driving the wedges (B) and (B) in the directions of the arrows (P) and (P). Then, the front part of the gold concrete (A) is press-fitted into the ring body insertion fitting fixing groove (11) of the vertical beam (T ₂ ), and the metal joint concrete (A) and the wedge body (B) are inserted. By horizontal beam (T ₁ ) and vertical beam
(T ₂ ) is securely fixed.

(Effect) In the beam joining using the present invention, unlike the conventional brazing or bolt joining method, the joining metal fitting is not exposed to the outside remarkably, so that there is no defect that the appearance is unsatisfactory. It has an excellent practical effect, such as not hindering the attachment of the beam like a ring-shaped joint fitting.
