DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a use state of an embodiment of the present invention. A building frame B is composed of a deck plate 18 made of corrugated steel plate and a concrete slab layer 19 cast on the upper surface thereof. Both ends of a strut member 22 made of a metal band plate slightly loosely bent in a V-shape are engaged with engagement grooves 21 and 21 provided on the side wall of the groove portion 20 of the deck plate 18. The suspension bolt 5 is penetrated through the center of the strut member 22, and the nut 23 is screwed into the bolt 5a at the upper end thereof, so that the suspension bolt 5 is attached from the building frame B by the strut member 22 in a hanging manner. The building aggregate A is hung on the lower end of the bolt 5 by the hanger C according to the embodiment of the present invention. Then, for example, a ceiling board 24 is fixed to the lower surface side of the building aggregate A with screws or an adhesive. The structure for attaching the upper end of the suspension bolt 5 to the building frame B is not limited to the above-described embodiment, but may be a known structure, for example, the suspension bolt 5 may be mounted to the building frame B by an insert metal fitting. Good.

FIG. 2 is a front view of the suspension device C in a state of crossing the building aggregate A, FIG. 3 is a side view, and FIG. 4 is a sectional view taken along line AA of FIG. FIG. 5 is a sectional view taken along line BB of FIG. FIG. 6 is an exploded perspective view of each member constituting the suspension device. The following description can be better understood especially with reference to the perspective view of FIG.

That is, as described above, the building aggregate A is composed of a main body 1 having a generally upwardly-U-shaped cross section including a bottom piece 1a and left and right side pieces 1b, 1b rising from both left and right sides of the bottom piece. The engaging pieces 2, 2 are formed by bending slightly downward from the upper edges 2a, 2a of the both side pieces in the direction opposite to each other, and are formed to extend in the longitudinal direction by a metal material.

The hanging device C includes a lower surface side nut member 3 located on the lower surface side of the engaged pieces 2 and 2 of the building aggregate A, and an upper surface side nut member located on the upper surface side thereof. A lower nut that is threaded into the lower nut member 3 and that is screwed into the lower nut member 3 to tighten the upper nut member 4. The engaged pieces 2 and 2 of the building aggregate A are engaged from below by the nut member 3, and the engaged pieces 2 and 2 are pressed from above by the upper nut member 4, and are engaged. The pieces 2 are suspended between the lower nut member 3 and the upper nut member 4 so as to be hung.

To be more precise, the lower surface side nut member 3 has a substantially rectangular lower surface side flat plate portion 8 having a screw hole 7 for screwing the hanging bolt 5, and upwardly from both right and left edges of the flat plate portion 8. Engaging pieces 9 and 9 which bend and engage the engaged pieces 2 and 2 from the lower surface side, and front and rear rising pieces 10 and 10 which are bent upward from both front and rear edges of the flat plate portion 8 and rise. Guide pieces 11, 11 protruding in the left-right direction are provided on the left and right end edges of the front and rear rising pieces 10, 10. Guide grooves 12, 12 fitted along the engagement pieces 2, 2 are formed.

The upper surface side nut member 4 is formed so as to be entirely larger in diameter than the lower surface side nut member 3, and has a substantially rectangular upper surface side flat plate portion having a through hole 13 through which the hanging bolt 5 penetrates. 14 and the left and right regulating pieces 15, 15 bent downward from the left and right edges of the flat plate portion 14 and contacting the left and right pieces 1b, 1b of the building aggregate A, and downward from the front and rear edges of the flat plate portion 14. The front and rear restricting pieces 16, 16 are bent and come into contact with the front and rear rising pieces 10, 10 of the lower surface side nut member 3.

In particular, the center portion 14a of the upper flat plate portion 14 of the upper nut member 4 and the left and right shift portion 14b with which the upper edges 2a of the engaged pieces 2, 2 abut. It is characterized in that a step 17 is formed so that the portion 14a bulges in a convex shape.

In order to use the suspension device C of the embodiment of the present invention having the above configuration as shown in FIG. 1, first, as shown in FIG. , 12 are attached to the building aggregate A so as to fit along the left and right engaged pieces 2, 2 of the building aggregate A. Next, the upper nut member 4 is moved so that the right and left restricting pieces 15, 15 of the upper flat plate portion 14 are along the outer surfaces of the left and right pieces 1b, 1b of the building aggregate A. The lower nut member 3 is superimposed on the lower nut member 3 along the outer surfaces of the front and rear rising pieces 10, 10 of the lower nut member 3.

As a result, the through hole 13 of the upper flat plate portion 14 of the upper nut member 4 and the screw hole 7 of the lower flat plate portion 8 of the lower nut member 3 are concentrically positioned. The lower end bolt portion 5b of the hanging bolt 5 attached in a hanging manner as described above is inserted into the through hole 13 and screwed into the screw hole 7, and then screwed into the lower end bolt portion 5b. By bringing the nut 6 into contact with the upper flat plate portion 14 of the upper nut member 4 and strongly tightening it, the building aggregate A is hung on the building frame B by the hanger C of the present invention. .

That is, as shown in FIG. 2 or FIG. 4, the lock nut 6 is brought into contact with the upper flat plate portion 14 of the upper nut member 4 so that the left and right engaged pieces of the building aggregate A are formed. 2 and 2 are sandwiched between the engagement pieces 9 and 9 of the lower surface side nut member 3 and the upper surface side flat plate portion 14 of the upper surface side nut member 4. It will be sandwiched between the members 3 and 4 and will be reliably suspended.

In particular, as shown in FIG. 2, FIG. 4 or FIG. 6, the upper flat plate portion 14 has a central portion 14 a on the through hole 13 side and upper edges 2 a, 2 a of the engaged pieces 2, 2 from the lower surface side. A step 17 separates the left and right abutting portions 14b from contact with each other, and the central portion 14a protrudes in a convex shape by the step 17; Due to the elastic deformation of the step 17, the left and right shift portions 14b strongly press the upper edges 2a, 2a of the engaged pieces 2, 2, so that the building aggregate A is engaged with the left and right engaged portions. Engagement of the lower side nut member 3 that abuts on the left and right side portions 14b of the upper flat plate portion 14 that abuts the upper edges 2a, 2a of the pieces 2, 2 and the lower surfaces of the two engaged pieces 2, 2. Strongly grasped by the pieces 9 and 9, the building aggregate A is Does not move unexpectedly in the longitudinal direction, i.e., in the front-back direction.

According to the embodiment of the present invention, since the guide grooves 12, 12 are provided in the lower nut member 3 as described above, the lower nut member 3 is engaged with the building aggregate A by both engagements. Since the upper nut member 4 is provided with left and right regulating pieces 15 and 15 and front and rear regulating pieces 16 and 16, these regulating pieces 15 and 15 can be attached easily. 16, the upper nut member 4 can be easily superimposed on the lower nut member 3. In addition, by superposing the two nut members 3 and 4 in this manner, the through hole of the upper nut member 4 can be formed. 13 and the screw hole 7 of the lower surface side nut member 3 are automatically concentric, so that the suspension bolt 5 can be easily inserted and screwed from the through hole 13 to the screw hole 7.

As described above, according to the present invention, the building aggregate A can be very easily and firmly attached to the suspension bolt 5, and the construction is simple, so that it can be manufactured at low cost. .
