Embodiment Construction

[0112] figure 1 The example of the shape of the fastener of this invention and its usage state are shown. In this figure, fasteners are used to attach the support 51 to the base 41, and the support 51 is not directly connected to the base 41 made of concrete, but a base plate 42 made of metal is interposed therebetween. Therefore, the bottom plate 42 is equivalent to a supporting member for installing the pillar 51 , and the nut 46 is screwed to the anchor bolt 45 embedded in the base 41 , so that the bottom plate 42 is fixed on the upper surface of the base 41 . In addition, on the surface of the bottom plate 42, a plurality of female threads 47 are formed at specific positions for attaching fasteners.

[0113] The pillar 51 fastened to the bottom plate 42 corresponds to a coupling member, and is fixed in an upright state. The pillar 51 is formed by processing the laminated material into a slender section, and four locking pieces are screwed into its lower end surface to in...

Abstract

A fasting device which fastens a support member such as a foundation plate (42) to a connecting member such as a pillar (51) is composed of a bearing body (11), shock absorbing bodies (38), anchoring implements (55), etc. The bearing body (11) is disposed at the center of a space (S) where the support member and the connecting member face each other, and comprises a basic plate (12) which is in surface contact with the support member, a mounting plate (14) which is in surface contact with the connecting member, and connecting sections which connect both of these plates. The shock absorbing bodies (38) are formed using U-shaped leaf springs or the like, and are disposed at the outer edges of the space (S) where the support member and the connecting member face each other. Reaction forces are generated in the shock absorbing bodies (38) according to the displacement of the connecting member or the like.

Description

technical field [0001] The present invention relates to a fastener used for mounting a pillar on a base or fastening a cross member to a pillar in various wooden structures. Background technique [0002] Wood-structured buildings have so far been popular mainly for small-scale buildings such as houses, but in recent years, large-section laminated timber has tended to be produced and introduced into larger-scale buildings such as public facilities. The mainstream of wooden structure houses in Japan is the construction method of wooden shaft groups with foundations, pillars, and beams as the skeleton, but in larger buildings, large-section laminated timber is often built into a door shape. skeleton structure. In this wooden frame structure, it is essential to secure the rigidity of the fastening parts between members such as a base and a pillar, or a pillar and a beam, and a technique such as the following Patent Document 1 has been proposed. [0003] In Patent Document 1, t...
