Description

  The present invention relates to a heel support for fixing and supporting a ridge when the ridge is attached along an outer wall surface of a building.

  Conventionally, various types of scissors support have been developed. For example, a pair of support frame portions curved in a semi-annular shape are combined into an annular shape, and one opposing end portion can be rotated with respect to each other. It is widely known that it is pivotally attached and the other opposing end portions are connectable to each other, and further, one support frame portion is integrally provided with a support leg portion for fixing to the outer wall surface of the building. However, according to such a scissors support tool, since the outer diameter of the scissors is slightly different from the design dimensions, the scissors are supported by the pair of support frame portions formed in the semi-annular shape. If the outer diameter of the heel is slightly smaller than the design size when supported in the inserted state, the heel is pinched and supported by these support frame parts, and rattling occurs and stable. While it becomes difficult to support, the outer diameter of the collar is larger than the design dimension , When sandwiching the 該竪 trough in inserted condition by the pair of support frame portion, there is a possibility that it becomes difficult to coupling of the support frame portions.

On the other hand, as described in Patent Document 1, fixing pieces are provided in parallel to each other toward the outside at both ends facing the abutting state of the support member made of an annularly curved band body. Also known is a scissor support that is configured so that after the scissors are inserted through the support metal fittings, the diameter of the support metal fittings is reduced and pressed against the outer peripheral surface of the scissors by tightening between the two fixing pieces with screws. It has been.

  However, since the support fitting made of the band body is formed in an annular shape, it is difficult not only to attach the heel to the heel when the heel is supported. The fixing pieces are joined by tightening screws to reduce the diameter of the support bracket and press the inner peripheral surface thereof to the outer peripheral surface of the flange. There is a problem that the construction efficiency is lowered, and the support force of the hooks by the support metal fittings depends on the magnitude of the tightening force of the screw, so that a uniform hook support structure cannot be obtained.

  Further, in order to stabilize the support of the heel, in Patent Document 1, a pair of protrusions are provided on the inner peripheral surface of the support fitting with a small gap in the circumferential direction, and these protrusions are connected to the protrusions. Although it is disclosed that the heel is supported by three points with the inner peripheral surface portion of the support fitting on the diameter line passing through the central portion of the boss, when the tightening force by the screw is large, the protrusion is There arises a problem that the outer peripheral surface is pressed with a larger pressing force than necessary and the ridge is recessed or damaged.

  The present invention has been made in view of such problems, and the object of the present invention is to ensure that the support operation of the kite can be performed reliably and efficiently, and the outer diameter of the kite is an error relative to the design dimension. Even if this occurs, the error can be elastically absorbed to prevent stable play with a constant clamping pressure without causing backlash and the like, and there is no risk of dents or damage to the heel.樋 To provide support.

It is characterized in that it protrudes in the circumferential direction so that it can be bent and deformed, and a protrusion that presses against the outer peripheral surface of the ridge is provided at the tip of this bullet piece.

  The invention according to claim 3 is characterized in that the bullet pieces are provided on the arc-shaped support surfaces of the left and right fixed arm pieces, respectively.

  According to the saddle bracket of the present invention, the curved support frame piece is placed in a state where the arc-shaped support surfaces of the left and right support arm pieces receive one half of the outer peripheral surface of the predetermined part in the longitudinal direction of the saddle. By covering the other half of the outer peripheral surface of the heel, not only can the heel support work be performed easily, but the base end of the curved support frame piece can be rotated to the tip of one support arm piece. Since it is pivotally attached and its tip is locked to the tip of the other support arm piece, it can efficiently support the rod without using bolts and nuts. In addition, the tip end projections of the projecting pieces provided with the flanges on the arc-shaped support surface at intervals in the circumferential direction, and the inner circumference of the arc-shaped support surface of the curved support frame piece facing these projections Since it can be supported by the three points with the surface part, stable support of the heel without rattling In addition, the elastic piece with a protrusion that press-contacts the outer peripheral surface of the heel is elastically deformed in the radial direction, and even if the outer diameter of the heel has an error with respect to the design dimension, the error is elastic. The protrusion at the tip of the bullet piece can always be pressed against the outer peripheral surface of the heel with a constant pressing force while absorbing it efficiently, and the heel is securely and firmly supported without causing dents or damage to the heel. be able to.
