Description

In the present invention, H-shaped steel and C-shaped steel used as beam members and other construction materials are used as horizontal base materials in the equipment construction of structures, and lip channel steels and equilateral angle steels are attached to the horizontal base materials as horizontal supports. The present invention relates to a shaped steel fixing bracket for fixing shaped steels in a crossed manner when the pipes and equipment are suspended at a predetermined position.

Conventionally, as a shaped steel fixing bracket for fixing this kind of shaped steel to each other in a cross shape, for example, a fixing portion provided with a tightening bolt that can move forward and backward in a screw hole and extending from the fixing portion in a substantially L shape. A plate-shaped metal fitting is disclosed which comprises a support portion which is arranged to face the fixed portion via a connecting portion and has a rectangular opening for inserting a horizontal support member from the connecting portion to the supporting portion. There is.
As a method of its use, a lightweight channel steel is inserted into the opening of the metal fitting on the bottom surface of the flange of the H-shaped steel used as the beam material of the structure, and the electric wire is included and attached to the raceway member or the opening. It is used as a member for suspending pipes and the like by attaching suspension bolt supports, but it is arranged so as to be stacked in a crossed manner, and the tightening bolts are tightened and sandwiched to fix them.

In this metal fitting, when the opening surface of the lightweight channel steel is arranged in the direction opposite to the tightening direction of the tightening bolt, even if the opening surface of the lightweight channel steel is deformed in the opening direction due to the tightening force of the tightening bolt, the opening It is restricted to both sides and can be securely fixed without deformation.
When lip groove steel is used as a horizontal support material for suspending pipes or the like using this type of metal fitting, it is generally used with the opening facing the side surface, and in that state, it is often used. When tightened with a tightening bolt, the opening cannot be securely fixed because the reaction force is weak and the opening is easily deformed in a cantilevered state.
When equilateral angle steel is used as the horizontal support material, it is generally arranged in an L-shape or an inverted L-shape, and the horizontal side of the equilateral angle steel is in contact with either the upper or lower surface of the H-shaped steel flange portion. In the state, the tightening bolt is tightened and fixed, but because it is L-shaped, the reaction force against the tightening force of the tightening bolt applied to the horizontal side is received at the tip of the other vertical side, and rotation due to eccentricity occurs and it is securely fixed. Can't be done.
That is, in this form of metal fitting, the reaction force is weak and does not have a predetermined strength with respect to the tightening direction of the tightening bolt as in the case of lip channel steel, or eccentricity with respect to the tightening direction as in the case of equilateral angle steel. There was a problem that it could not be used.

It is a plate-shaped metal fitting body provided with a rectangular opening through which the horizontal support material is inserted from the support portion to the support portion, and the horizontal base material which is vertically overlapped with the horizontal support material inserted through the opening portion is fixed. In the shaped steel fixing bracket that is sandwiched and fixed by tightening the tightening bolt of the portion, the equilateral angle steel that protrudes inward from the end edge of the opening on the side opposite to the tightening direction of the tightening bolt and serves as a horizontal support material. It is characterized by providing a support piece that supports the horizontal side.

According to the shaped steel fixing bracket of the present invention, the tightening bolt is tightened by providing a support piece that protrudes inward from at least one of both side edges of the opening and is inserted into the opening of the lip channel steel as a horizontal support material. At this time, the support piece inserted into the opening of the lip channel steel supports one end of the opening, and the opening can be securely fixed without being deformed.

In addition, by providing a support piece that supports the horizontal side of equilateral angle steel arranged in an L shape that protrudes inward from the edge of the opening on the opposite side of the tightening direction of the tightening bolt and serves as a horizontal support material. When tightening the tightening bolt, the support piece supports the horizontal side of the equilateral angle steel from the inside coaxially with the tightening bolt, so that the equilateral angle steel can be prevented from rotating and can be securely fixed. It can be resolved.
