DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a convex curved surface with which a bracket attached to a vertical member such as a cubic or vertical frame comes into contact,
The present invention relates to a vertical member mounting position adjusting member for adjusting the verticality of the vertical member by the convex curved surface.

[0002]

2. Description of the Related Art A vertical member such as a curtain wall or a vertical frame of a curtain wall is fixed directly or indirectly to a frame such as a floor slab in order to secure its verticality. A state in which the bracket joined to the vertical member is brought into contact with the adjustment member joined to the vertical member side of the fastener having the vertical member side, and the surface on the vertical member side has a convex curved surface, and the angle around the in-plane horizontal axis of the curtain wall is adjusted. Supported by fasteners.

In some cases, the adjusting member is formed as a part of the fastener. However, the adjusting member is manufactured separately from the fastener as shown in Japanese Utility Model No. 2503833 because the surface in contact with the bracket is formed as a convex curved surface. In this case, it is necessary to temporarily fix the adjusting member to the fastener by screwing or welding when adjusting the height and angle of the bracket.

In the case where the adjusting member is temporarily fixed by screws, the adjusting member must be provided with a screw hole for a temporary fixing screw in addition to a bolt hole for a bolt for joining the bracket to the fastener. There is an increasing problem.

SUMMARY OF THE INVENTION In view of the above background, the present invention proposes an adjusting member capable of easily performing temporary fixing by reducing the number of processes for forming a screw groove or the like when the adjusting member is temporarily fixed to a fastener with a screw. is there.

[0006]

According to the present invention, a thread groove into which a temporary fixing screw penetrating through the fastener is screwed is formed in a part of the cross section of the convex curved surface portion contacting the bracket in the longitudinal direction of the adjusting member. By doing so, it is possible to form a screw groove only by extruding the adjusting member, and it becomes unnecessary to drill a temporary fixing screw, thereby reducing the number of processing.

The thread groove is formed from the surface on the fastener side to a halfway depth on the bracket side in the thickness direction of the convex curved surface portion.
By being extruded, it is formed continuously in the longitudinal direction of the adjustment member.

[0008] The adjusting member is easily temporarily fixed to the fastener when the temporary fixing screw passes through the fastener and is screwed into the screw groove of the adjusting member. Since the screw groove of the adjusting member is formed continuously in the longitudinal direction of the adjusting member, the temporary fixing screw is screwed into the screw groove, and the adjusting member is temporarily fixed to the fastener when the adjusting member is temporarily fixed to the fastener. The position can be adjusted in the longitudinal direction.

The adjusting member is joined to both a bracket which is joined to a vertical member such as a slab or a vertical frame and a fastener which is fixed to a frame such as a floor slab, and has a convex surface on the bracket side. The verticality of the vertical member is adjusted by the bracket coming into contact with the curved surface of the convex curved surface portion having the curved surface.

Since the adjusting member is joined to both the bracket and the bolt by a bolt penetrating the fastener, it is necessary to make a bolt hole in the fastener and the adjusting member at a position where the temporary fixing screw is removed. When the fastener is opened from the side, burrs protrude from the surface of the fastener on the adjustment member side, and the burrs deteriorate the adhesion between the adjustment member and the fastener.

[0011] In order to solve this problem, according to the second aspect, a groove having a width larger than the diameter of a bolt penetrating the bracket and the fastener is formed from the surface on the fastener side above and below the fastener side of the screw groove. The contact between the fastener and the adjustment member is avoided, and a state is ensured in which the surface of the adjustment member on the fastener side is completely adhered to the surface of the fastener around the bolt hole on the adjustment member side. The groove is formed continuously in the longitudinal direction of the adjusting member, corresponding to the fact that the screw groove is formed during extrusion molding.

According to a third aspect of the present invention, when an engaging portion for downwardly engaging the upper end of the fastener is formed on the upper portion of the adjusting member, the adjusting member is supported by the fastener during temporary fixing. Since the adjustment member can be stabilized, the fastener can be temporarily fixed to the fastener with the temporary fixing screw.

According to a fourth aspect of the present invention, when a receiving piece that can be engaged with a height adjusting bolt screwed into the bracket projects upward from the upper bracket side, the adjusting member of the height adjusting bolt is provided. From falling off is prevented.
