Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an L-shaped steel, a channel steel, and other construction materials in a building structure, and suspends an erecting member such as a wiring part such as a water pipe or a sewer pipe from the construction material. The present invention relates to a hanging support metal fitting for being lowered.

[0002]

2. Description of the Related Art Conventionally, a downward holding portion for holding a construction material from above as a suspension support fitting which is mounted and fixed to the construction material for the purpose of suspending and supporting various construction members such as piping from various construction materials. And an upward holding portion parallel to the downward holding portion and for sandwiching the construction material from below are formed in a side U shape, and a tightening bolt is attached to the downward holding portion, and the upward holding portion is provided. For the part, a suspending tool for holding the above-mentioned erection member, for example, for connecting a piping band in a freely changeable direction, for example, a hanging support fitting to which a support member for connecting to a hanging tanbuckle is used.

[0003] When such a suspension support is attached to a construction material such as an L-shaped steel or a channel steel, the construction material is fitted between the upward holding portion and the downward holding portion, and the fastening member attached to the downward holding portion is attached. The bolts are screwed in and fixed by pressing the upward holding portion against the construction material. Therefore, the distance between the downward holding portion and the upward holding portion must be such that the building material can be fitted in and the bolt can be screwed down. Therefore, when the thickness or the vertical width of the construction material is different, a plurality of suspension support fittings that are adapted to the respective thicknesses or vertical widths are required.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a hanging bracket having improved versatility which can be used without being limited by the size of a construction material. .

[0005]

According to a first aspect of the present invention, there is provided:
A hanging support fitting suspended and fixed to a predetermined building material, a downward holding portion for sandwiching the building material from above, and an upper member having a descending portion extending downward from the downward holding portion, A lower member having an upward holding portion for sandwiching the construction material from below and an ascending portion extending upward from the upward holding portion, wherein the lower member and the lower member ascend. The part is adjustable in length and can be connected and fixed by a connecting member. A fastening member for fastening and fixing a building material projecting downward is attached to the downward holding portion of the upper member, and the building material is attached to the lower member. And a support member for suspending the erection member or the like is attached thereto.

[0006] Since the suspension bracket is divided into an upper member having a downward holding portion and a lower member having an upward holding portion, the size of a building material such as an L-shaped steel or a channel steel of a building structure is reduced. It can be sandwiched together. Further, since the length of the descending portion of the upper member and the ascending portion of the lower member can be adjusted and connected and fixed by the connecting member, it is possible to cope with construction materials of various sizes and thicknesses. Further, fine adjustment can be made by a fastening member attached to the downward holding portion of the upper member.

[0007] Since it is possible to cope with construction materials of various sizes even with a suspension support fitting of the same shape and the same size, it is possible to appropriately change the support member attached to the lower member according to the purpose of use. The types of erecting members and the like that are lowered and extended also increase, and work efficiency is improved.

A second aspect of the present invention is characterized in that the lower member has a flat plate portion projecting from the upper end of the upward holding portion to both left and right sides.

When the flat plate portion is brought into contact with the lower surface of the construction material, and the lower end of the fastening member attached to the downward holding portion of the upper member is pressed against the upper surface of the construction material, the construction material and the lower member have a wide contact. Since the contact surfaces can be shared, the suspension bracket is firmly attached to the building material.

A third aspect of the present invention is characterized in that the ascending portion of the lower member has a reinforcing piece.

Since the reinforcing piece is provided at the ascending portion of the lower member which is most heavily loaded, the hanging support has sufficient strength even if it is divided into an upper member and a lower member.
