Description

  The present invention relates to a rectangular steel hanging bracket, and more particularly to a rectangular steel hanging bracket used to suspend a ceiling base or the like.

  As a hanging metal fitting used for suspending a ceiling base or the like, as shown in FIG. 8, one that has been used by being hooked on a lip portion y ′ of a C-shaped steel Y ′ has been frequently used. A support portion 2 'for attaching a suspension bolt 3' is formed at the lower end of the suspension fitting X '. In this case, since the C-shaped steel Y 'has the lip portion y', it is only necessary to hook the hook-shaped locking portion 1 'formed at the upper end of the hanging bracket X' on the lip portion y '. There is also an advantage that the position for lowering the suspension bolt can be freely adjusted in the direction of action.

  By the way, in recent years, square steel (for example, square steel in which both ends are caulked at a corner portion) has been frequently used instead of C-shaped steel. This square steel is more resistant to twisting than the C-shaped steel and has a closed cross section, so that the strength is dramatically increased, and is advantageous in terms of weight reduction, accuracy (for example, flatness) and cost. However, in the case of square steel, since there is no portion for hooking the hanging bracket, it is impossible to use the one for C-shaped steel as it is. Therefore, a method of using a simple L-shaped hanging bracket is conceivable. However, in the case of an L-shaped hanging bracket, it is necessary to screw it to the side surface of the square steel in advance, and once it is attached, the mounting position is changed. There is a problem that it is impossible to change.

This type of hanging bracket is composed of a pair of hangers each having a holding portion having a substantially U-shaped cross section for holding a channel member for anti-fretting penetrating perpendicularly to a square steel from a direction perpendicular thereto. Some have already been proposed (see, for example, Patent Document 1).

JP 2001-200609 A

However, in the case of the hanger device disclosed in Patent Document 1, a holding portion having a substantially U-shaped cross section for holding a channel member for anti-fretting penetrating so as to be orthogonal to the square steel from an orthogonal direction. Since the pair of hangers are provided, the number of parts is increased, the assembly work is complicated, and the cost is disadvantageous.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a square steel hanger having a simple structure and excellent workability.

In the present invention, as a first means for solving the above-mentioned problems, in a square steel hanging metal fitting used to suspend a ceiling base or the like, it is fitted from a direction orthogonal to a square steel having a quadrangular cross section. , fit the U-shaped cross section ing a pair of side edges provided vertically integrally from both ends of the upper side and the upper side along the top surface of the rectangular steel along the sides of the rectangular steel insertion part and the fitting insertion portion together they constitute the support part which is bent integrally formed horizontally to the lower end of the hand only sides in, to the support part, is mounted a hanging bolts used to suspend the ceiling foundation like.

By configuring as described above, it is possible to set the hanging bracket by simply fitting the fitting insertion portion from the direction orthogonal to the square steel having a quadrangular cross section used to suspend the ceiling foundation and the like, Since the set hanging bracket can be easily moved along the square steel, the configuration is simplified, and the hanging position of the base material suspended by the hanging bolt can be easily adjusted. Moreover, only one of the side edges in the U-shaped insertion section formed of an upper side along the upper surface of the square steel and a pair of side edges vertically extending from both ends of the upper side along the side surface of the square steel. Since it is only necessary to form a support part integrally with the lower end of the horizontal , the structure is simplified.
