Description

  The present invention relates to a fastening metal fitting for connecting a concrete foundation of a building and a vertical member such as a column or a vertical wall of a wall standing on a foundation laid horizontally on the concrete foundation.

  A structure that connects the foundation horizontally installed on the concrete foundation of the building and the pillar standing on this foundation with a reinforcing metal fitting has been practiced in the past, but in this way the structure simply connects the foundation and the pillar. In such cases, sufficient strength may not be obtained against external forces such as earthquakes and strong winds. In particular, when there is a large shaking due to a large earthquake or the like, there are many wooden buildings where the pillars are pulled up (disengaged) from the base, and thus collapse.

  From this point of view, in recent years, in order to obtain sufficient strength (seismic strength), it is strongly desired to implement a connection structure that connects a concrete foundation (hereinafter simply referred to as a foundation) and a pillar, not a foundation and a pillar. It is rare.

  By the way, as a connection structure which connects a foundation and a pillar in this way, it is disclosed by Unexamined-Japanese-Patent No. 2000-064422 (patent document 1) and Unexamined-Japanese-Patent No. 2003-3006974 (patent document 2), for example. In this way, the foundation and the column are tightly connected by connecting and fixing the connecting hardware (hole-down hardware) attached to the side of the column and the anchor bolt that passes through the base from the foundation and protrudes upward. The structure to do is common.

  Therefore, in order to implement the above-mentioned structure for connecting the foundation and the pillar, anchor bolts are erected according to the standing position of the pillar in order to connect to the hole-down hardware attached to the pillar. Required.

  However, because anchor bolts are originally constructed when the foundation is constructed (when concrete is cast and the foundation is formed), the lower side of the anchor bolt is embedded in the foundation and integrated to stand upright in this foundation. It cannot be retrofitted to an already built building.

  Therefore, a retrofit type anchor bolt for retrofitting to a foundation of a built building has been proposed in the past, however, this retrofit type has a vertical groove formed in the base from above, and this vertical groove is formed in the vertical groove. The anchor bolt is inserted and the adhesive is filled into the groove to fix it, so it is absolutely stronger than the original anchor bolt that is embedded in the foundation and integrated with the foundation (particularly pulling upward) Strength).

  Further, as disclosed in, for example, Japanese Patent Application Laid-Open No. 06-065931 (Patent Document 3), the vertical groove drilled in the foundation is not simply a straight shape, but has a shape having an expansion space at the lower portion. Improved pull-out strength, such as a structure that prevents the lower part of the anchor bolt from falling into the expansion space below the vertical groove by expanding the lower part of the inserted anchor bolt in the widening space (see Patent Document 3 and FIG. 4). Although the retrofit type has been proposed in the past, the construction is inevitably complicated and the construction is troublesome. In addition, the high pull-out is the same as the original anchor bolt that is embedded in the foundation and integrated with the foundation. It was difficult to obtain strength.

  As described above, in recent years, there has been a strong demand for connection between a foundation and a pillar from the viewpoint of strength such as earthquake resistance, and there are many cases where an anchor bolt is required for an already built building (in particular, In the case of a building constructed by an old construction method, anchor bolts are erected in advance at major vertical members such as large black pillars and corner pillars. Anchor bolts are rarely erected on vertical members, and additional anchor bolts are required if you want to attach hole-down hardware to these other vertical members and connect them to the foundation.) However, there is no effective means for easily attaching an anchor bolt having sufficient strength (pullout strength) to a desired position on the foundation.

Japanese Patent Laid-Open No. 2000-064422 JP 2003-306974 A Japanese Patent Application Laid-Open No. 06-065931

  The present invention has been completed in view of such a current situation, and by mounting and fixing the foundation installation plate on the concrete foundation, the screw collar portion is arranged upright above the foundation on the concrete foundation.

The second through-hole 2b of the foundation side mounting plate portion 2 is formed in a hole shape that substantially matches the second fastening rod 10 that is inserted into the second through-hole 2b. The present invention relates to a fastening bracket according to claim 4.

  Since the present invention is configured as described above, it can be erected on the foundation above the center in the width direction of the foundation on the concrete foundation simply by attaching and fixing the foundation mounting plate on the side surface of the concrete foundation. A screw hook portion as an alternative to the anchor bolt can be easily disposed in a standing position at a desired position corresponding to the vertical position of the vertical member, and the screw portion at the tip of the screw hook portion is connected to the vertical member. It is possible to easily realize the connecting structure between the vertical member and the concrete foundation by screwing and fixing the connecting metal fitting attached to the side surface.

  In addition, the foundation installation plate is fixed to the side of the concrete foundation (fixed from the side with respect to the concrete foundation) and is inserted into a conventional retrofit anchor bolt (vertical groove drilled in the foundation). It is excellent in pulling strength upward as compared with (fixed by), and thus it can be firmly prevented that the vertical material is pulled upward from the concrete foundation or foundation, and the conventional retrofitting type anchor bolt It is also possible to realize an excellent earthquake-resistant structure that is not available.

  Therefore, the present invention can achieve the connection between the vertical member erected at the place where the anchor bolt is not erected and the concrete foundation without troublesome construction and complicated structure, and the conventional retrofitting type anchor bolt.

  Further, in the inventions according to claims 4 and 5, since the foundation installation plate portion can be more securely attached and fixed to the side surface of the concrete foundation, the concrete foundation and the longitudinal member can be more reliably secured. It is a metal fitting for fastening that excels in practicality.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  Inserting a fixing rod 3 such as a driving rod or a fixing bolt inserted into the through-hole 2a of the foundation installation plate portion 2 into the side surface of the concrete foundation 1 or an insertion formed on the side surface of the concrete foundation 1 By inserting and fixing to the part 5, the foundation installation plate part 2 is attached and fixed to the side surface of the concrete foundation 1 in the installation state.

  Here, the screw rod part 4 provided in a projecting state upward on the foundation side installation plate part 2 is fixed to the base side installation plate part 2 with the base end part thereof, and the tip part thereof. The upper part is arranged in a standing state above the center part in the width direction of the base 6, not on the side upper side of the base 6 laid horizontally on the concrete foundation 1.

  Accordingly, the vertical member 7 (for example, a column or a vertical wall of a wall) is provided so that the screw portion 4a at the tip of the screw rod portion 4 standing upright above the center in the width direction of the base 6 is erected on the base 6. The vertical member 7 and the concrete foundation 1 can be tightly connected by screwing and fixing to a connecting metal fitting 8 (for example, a hole-down metal fitting) provided on the side surface.

  In addition, as described in the above-mentioned conventional example, the conventional retrofitting type anchor bolt is structured to be inserted into a vertical groove drilled in a concrete foundation and fastened and fixed with an adhesive or the like in the groove. There was a problem that it was weak, but in this respect, in the present invention, the fastening rod 3 inserted into the through hole 2a of the foundation mounting plate portion 2 is driven into the side surface of the concrete foundation 1 or the fastening rod. 3 is inserted and fixed in the insertion portion 5 formed on the side surface of the concrete foundation 1, and the foundation side mounting plate portion 2 is fixed to the side surface of the concrete foundation 1 in a side-by-side state (closely). As compared with the conventional example, it is possible to secure a very high pulling strength.

  Therefore, the present invention can be used as an alternative to an anchor bolt at a desired position corresponding to the standing position of the longitudinal member 7 simply by mounting and fixing the foundation installation plate portion 2 at a desired position on the side surface of the concrete foundation 1. The screw hook part 4 can be easily arranged in an upright state, and thus the connecting member 8 of the vertical member 7 is screwed onto the screw hook part 4a which is superior in pulling strength as compared with the conventional retrofitting type anchor bolt. By fixing, the vertical members 7 where the anchor bolts were not erected can be easily and firmly fixed to the concrete foundation 1, making it possible to easily implement a connection structure with excellent earthquake resistance. It becomes a secure fitting metal fitting.

  In addition, for example, the screw flange portion 4 is disposed on the side of the concrete foundation 1 to which the foundation side mounting plate portion 2 is attached and fixed, and the upper portion is disposed on the distal end side. When the base 6 is arranged in a standing state above the center in the width direction, and is formed in a curved shape or a bent shape by connecting the base end portion and the distal end portion via a curved portion or a bent portion. For example, the present invention can be designed and realized with a simple configuration in which the screw flange portion 4 simply formed by bending or bending the saddle member is fixed to the base side installation plate portion 2 constituted simply by a flat plate material. Therefore, it will be further excellent in mass productivity.

  In particular, for example, the screw flange 4 has a curved portion or a bent portion that bends or bends the screw flange 4 in the width direction of the base 6 at a position close to the base 6 above the base 6. When formed into a shape, the screw flange 4 extends upward from the side of the concrete foundation 1, and immediately reaches the upper position of the base 6, immediately from the upper side of the base 6 to the center in the width direction. Since it bends or bends upward, the long range of the distal end portion of the screw rod portion 4 can be arranged upright above the center portion in the width direction of the base 6. That is, a portion that plays a role as an alternative to the anchor bolt (portion disposed in a standing state above the center in the width direction of the base 6) can be formed in the screw flange portion 4 in a long range, and accordingly, the screw rod The connection between the portion 4 and the connecting member of the longitudinal member 7 can be performed more satisfactorily.

  In addition, for example, the base side installation plate portion 2 forms a second through hole 2b different from the through hole 2a, and a second fastening rod 10 fitted into the second through hole 2b is provided. The base side mounting plate portion 2 is fixedly attached to the side surface of the base 6 by being inserted into and fixed to the insertion portion 9 formed on the side surface of the base 6 by being driven into the side surface of the base 6. In the case where it is configured to be able to, the foundation side mounting plate part 2 is fixed not only to the side surface of the concrete foundation 1 but also to the side surface of the foundation 6, whereby the vertical member 7 is fixed to the concrete foundation 1 and the foundation 6. Therefore, the higher connection strength by the vertical member 7, the concrete foundation 1, and the base 6 will be obtained.

  In particular, for example, the through-hole 2a of the base-side mounting plate portion 2 is a long hole into which the fastening rod 3 is inserted in a loose fitting state in which the vertical movement of the fastening rod 3 is not permitted but left-right movement is permitted. The second through hole 2b of the base side mounting plate portion 2 is formed in a hole shape that substantially matches the second fastening rod 10 that is fitted into the second through hole 2b. For example, it is difficult to drive into the side surface of the concrete foundation 1 the fastening rod 3 that is obstructed by a hard member such as pebbles contained in the concrete foundation 1 and inserted into the through-hole 2a of the mounting plate 2 on the foundation If the insertion part 5 into which the fastening rod 3 is inserted cannot be drilled, the placement position of the fastening collar 3 and the insertion position of the insertion part 5 are shifted to the left and right to avoid pebbles. In addition, the fixing rod 3 can be moved left and right with respect to the through-hole 2a but not allowed to move vertically. Since the second through-hole 2b has a shape substantially matching the second fastening rod 10, the base-side installation plate portion is formed by making the through-hole 2a into a long hole shape. The attachment strength of 2 (the pulling-out strength upward) is not weakened. Therefore, the attachment of the foundation installation plate portion 2 can be performed more reliably and satisfactorily.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In this embodiment, a concrete foundation 1 of a building and a vertical member such as a pillar or a vertical wall of a wall standing on a foundation 6 placed horizontally on the concrete foundation 1 are tightly connected. By forming a through hole 2a into which a fastening rod 3 such as a fastening bolt or the like is inserted, and driving the fastening rod 3 inserted into the through hole 2a into the side surface of the concrete foundation 1, or concrete A foundation side mounting plate part 2 configured to be fixedly attached to a side surface of the concrete foundation 1 by being inserted into and fixed to the insertion part 5 formed on the side surface of the foundation 1, and the foundation side mounting plate part 2 and a screw flange 4 provided in a projecting state upward from 2, and the screw flange 4 is fixed to the base mounting plate 2 with a lower portion as a base end portion and an upper portion as a tip portion. Concrete foundation 1 with the above-mentioned foundation installation plate 2 attached and fixed It is set as the structure arrange | positioned in the standing state above the width direction center part of this base 6 instead of the side upper side of the base 6 installed horizontally, and the screw part 4a of the front-end | tip part of the screw rod part 4 of this standing state Is a fastening bracket constructed such that the longitudinal member 7 and the concrete foundation 1 are fastened together by screwing and fixing to a connecting bracket 8 attached to the side surface of the longitudinal member 7 standing on the base 6.

  As shown in FIG. 1, the foundation side mounting plate portion 2 has a flat plate structure made of a flat plate material obtained by punching a metallic plate material into a predetermined shape by press molding. In addition, this foundation installation board part 2 is not restricted to flat form, For example, it forms in the cross-sectional U-shape or L-shape, and the shape which can be installed along the fitting state in the corner of the said concrete foundation 1 is formed. You may do it.

  As shown in FIG. 1, two through holes 2 a into which the fastening rods 3 are inserted and two second fastening rods 10 to be described later are inserted into the plate surface of the foundation side mounting plate portion 2. Two second through holes 2b are formed.
