Description

  The present invention relates to a hanging support used for supporting heavy objects such as kitchen hanging doors and ceiling fans.

  When a heavy object such as a kitchen hanging door or a ceiling fan is suspended and supported from the ceiling, it is suspended by using beams (H-shaped steel) existing on the back of the ceiling instead of the ceiling plate itself. Conventionally, as shown in FIGS. 7 (A) and 7 (B), the base wood 102 is struck and fixed between the upper and lower flanges of the adjacent beams 101, and the support wood 103 is attached to the base wood 102 with nails. It is fixed. Then, all screw bolts 104, which are suspension rods, are inserted into the vertical through holes formed in the support tree 103, and nuts provided on the upper and lower surfaces of the support tree 103 are tightened so that the all screw bolts 104 are suspended from the support tree 103. It is fixed.

  Patent Document 1 discloses a ceiling hanger comprising a beam mounting portion for mounting on a beam, an extension member extending from the beam mounting portion, and a main body connected to the extension member. The main body portion includes a pair of side walls extending in a direction substantially parallel to the beam and arranged to be opposed to each other in the vertical direction, and a connecting wall connecting the pair of side walls. In the position, there is disclosed a ceiling hanging object provided with an elastic engagement portion protruding inward from the inner surface of the side wall.

  However, in the conventional suspension support structure using the base wood 102, the work burden on the site is large, such as hitting and fixing the base wood 102. In addition, the base wood 102 may become thin due to aging, and rattling may occur. Furthermore, when all the screw bolts 104 are displaced from the position to be hung, such as a kitchen hanging door or a ceiling fan, it is necessary to perform the above operation again.

  Further, in the ceiling hanger described in Patent Document 1, the entire screw bolt 104 cannot be appropriately suspended between the beams 101.

  In view of the above circumstances, it is an object of the present invention to provide a suspension support tool that does not require base wood to be attached to a beam and can suspend and fix a suspension bar portion between the beam so that the position can be adjusted. To do.

  In order to solve the above-described problems, the present invention provides a horizontal member spanned between the lower flanges of adjacent beams and an end fixing for removably fixing the end of the horizontal member to the lower flange. And a suspension rod support portion that is movably attached to the horizontal member and fixed to the horizontal member at an arbitrary position, and a suspension rod portion that is supported by the suspension rod support portion. It is characterized by that.

  If it is the above-mentioned structure, since it has an end fixing tool that detachably fixes the end of the horizontal member spanned on the lower flange of the adjacent beam to the lower flange, without attaching the base wood to the beam The horizontal member can be fixed to the lower flange. Moreover, the said suspension bar part can be suspended and fixed to the arbitrary positions of the said horizontal member by the said suspension bar support part.

  The horizontal member is made of lip-groove steel, and the surface having an opening is arranged facing downward, and the suspension rod support portion has a frame portion that is externally fitted to the horizontal member, and the frame portion The tip of the bolt screwed upward from the lower side may be provided so as to be able to contact the back surface of the horizontal member through the opening of the horizontal member. Since a general lip groove steel is used as the horizontal member, the cost can be reduced. Further, when the surface having the opening is upward, the groove is deformed in the direction in which the groove is closed when a load is applied downward. However, when the surface having the opening is downward, such deformation does not occur. However, if it is turned downward, the groove is deformed in the opening direction. So we are preventing the 13b plate from opening

  The end fixture may include a frame portion that is externally fitted to the horizontal member, and a concave portion having a height higher than the thickness of the lower flange may be formed in the frame portion. According to this, reliable fixation can be performed in a state where the edge of the lower flange enters the recess.

  The suspension rod support portion may be a common product in which a concave portion identical to the concave portion of the end fixture is formed. According to this, cost reduction can be achieved by sharing components.

  According to the present invention, there is no need to attach the base wood to the beam, and there is an effect that the hanging rod portion can be suspended and fixed at an arbitrary position between the beam.
