[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a fixing bracket for a wooden building, for example, which joins horizontal members such as columns and beams.

[0002]

[Prior art]

 Conventionally, in the frame structure of a wooden building, various metal fittings have been used to fix a vertically standing pillar and a horizontal member such as a beam that is laid on the pillar. No. 407, Japanese Utility Model Laid-Open No. 4-110803, and the like are known. These joining brackets consist of a back plate that is formed by bending a single steel plate and attached to a pillar, and a pair of side plates that are bent at right angles so as to be parallel to each other from both side edges of the back plate. And is formed in a U-shape as a whole. Then, a pair of side plates is inserted into the slit opened at the joint end face of the horizontal member such as a beam, and the side plate and the beam are fixed by bolts penetrating the beam. Is fixed by bolts penetrating through the pillars. The joint fitting disclosed in Japanese Utility Model Application Laid-Open No. 3-54407 has two back plates in order to increase the strength of the back plate to which a vertical load such as a beam is concentrated.

As shown in FIG. 5, the conventional fixing bracket 50 is formed by bending a pair of side plates 52 from both side edges of a back plate portion 51 so as to be formed in a U-shape as a whole. Naturally, the slits 54 of the beams 53 into which the side plates 52 are inserted need to be formed in parallel with each other at intervals so as to correspond to the respective side plates 52. For this reason, for example, when joining a narrow beam 53 having a width of 100 mm or less, the interval L between the pair of slits 54 and the outer edge of the beam 53 becomes extremely narrow. There is a possibility that the joint 53 of the beam 53 will be broken from the portion and cracks will be generated. In other words, in this type of joint 50, the back plate portion 51 is fixed to the column 56 by the bolt 55, so that the width of the back plate portion 51 needs to be wider than the bolt 55, and the back plate portion 51 is extremely It cannot be formed narrow and requires a certain width. For this reason, in the fixing bracket 50 that bends the side plates 52 from the back plate portion 51, the interval between the side plates 52 is also formed according to the width of the back plate portion 51, so that the narrow beam 53 is fixed. However, the distance between the side plates 52 cannot be reduced according to the width of the beam 53. For this reason, when the narrow beam 53 is joined with the fixing bracket 50 bent in a U-shape, a crack is easily generated from the slit 54 structurally, and the strength of the beam 53 is significantly reduced, and the beam 53 is substantially reduced. There was a problem that 53 could not be fixed securely.

[0004] The present invention is intended to solve such a problem. When fixing a transverse member such as a narrow beam, it is possible to suppress cracks at a joint end face and securely fix the transverse member. The purpose is to provide fixing hardware for construction.
