  Hereinafter, an embodiment of a hanging bracket for a ceiling edge receiver according to the present invention will be specifically described with reference to the drawings. The hanging metal fittings H1 to H4 of the first to fourth embodiments are all formed by punching and bending from a single metal plate. In addition, while the same code | symbol is attached | subjected to the component which is common in these embodiment, description is abbreviate | omitted in 2nd-4th embodiment about the component demonstrated in 1st embodiment. In addition, the suspension metal fittings H1 to H4 of these embodiments and the common parts of the suspension metal fittings H and H0 having the conventional structure shown in FIGS. 9 and 10 described above, and the light weight using these suspension metal fittings. The same code | symbol is attached | subjected also about each structural member of the steel frame foundation frame.

  1 and FIG. 2, the hanging metal fitting H1 of the first embodiment includes a belt-like main body portion 1 extending in the vertical direction, and a suspension bolt mounting portion 2 that projects horizontally from the upper end of the main body portion 1 to the rear. A U-shaped field edge holder 3 that is bent forward from the lower portion of the main body 1 and opened upward is integrally formed, and a bolt insertion hole 21 is formed in the suspension bolt mounting portion 2. It has been drilled. The left and right side edges of the main body 1 and the suspension bolt mounting portion 2 are respectively provided with projecting edge portions 4 and 4 projecting rearward from the main body 1 over the suspension bolt mounting portion 2. In addition, the front wall 3a of the field edge holder 3 is bent into a generally U-shape so that the upper portion 31 brings the bent portion closer to the main body portion 1, and on both left and right sides of the bent portion. Are provided with retaining protrusions 5 and 5 which are separated by an L-shaped cut 32 and project rearward (inward) obliquely downward.

  In order to use the suspension metal fitting H1 having the above-described structure for the lightweight steel base frame of the building ceiling portion, the lower end portion of the suspension bolt F hanging from the ceiling slab S is connected to the suspension bolt mounting portion 2 as shown in FIG. The suspension bolt mounting portion 2 is sandwiched and fixed by a pair of upper and lower nuts G that are inserted into the bolt insertion hole 21 and screwed into the suspension bolt F, and the field edge receiver D is lowered by the field edge holder holding portion 3. Embrace and support. The field edge receiver D supports the ceiling field edge B attached to the ceiling board A via the hook member C as described above.

  In such a foundation frame, even if a large external force acts on the entire ceiling due to an earthquake shake or the like, the hanging metal fitting H1 has a protruding edge 4 that is continuous with both side edges extending from the main body 1 to the suspension bolt mounting part 2. , 4, the boundary between the main body 1 and the suspension bolt mounting portion 2 does not buckle or extend and opens, and the main body 1 and the suspension bolt mounting portion 2 maintain a rigidly perpendicular arrangement. At the same time, the main body 1 itself is also highly rigid and difficult to bend. Therefore, the field edge receiver D, the ceiling field edge B, and the ceiling board A maintain a certain distance from the ceiling slab S, and in the event of an earthquake, the entire ceiling part is swayed integrally with the building frame. Deformation, dropout and destruction of the ceiling can be reliably prevented. Therefore, by using the hanging metal fitting H1, high earthquake resistance is imparted to the lightweight steel base frame of the building ceiling.

  In addition, the edge receiving portion 3 of the hanging metal fitting H1 has a substantially U-shaped bend at the upper portion 31 of the front wall portion 3a and the opening on the upper side is narrowed. Since the retaining protrusions 5 and 5 projecting diagonally downward inward on both sides of the upper part 31 of the upper part 31 function as a means for preventing separation, even if a large vertical vibration is applied to the base frame using this, the field frame is received. The ceiling edge receiver D held by the holding portion 3 does not leave upward, and thus the distortion of the entire ceiling portion, local deformation, dropout and destruction of the ceiling portion can be more reliably prevented.

  In addition, as a detachment prevention means for preventing the upper detachment of the field ledge holder D held by the field ledge holder 3, as shown in FIG. Not only the stop protrusions 5 and 5 but various forms and mechanisms can be adopted. For example, in the hanging metal fitting H2 of the second embodiment shown in FIG. 4, the main body portion 1 and the suspension bolt mounting portion 2 and the projecting edge portions 4 and 4 of these side edges are the same as in the first embodiment. However, the front wall portion 3a of the field edge holding portion 3 is curved inwardly as a whole except for the lower portion, and protrudes obliquely downward inward by an upward U-shaped cut at the center in the width direction of the upper portion 31. A retaining protrusion 6 is formed, and the retaining protrusion 6 functions as a detachment preventing means for preventing the field receiver D from being separated upward.

  The suspension metal fitting H3 of the third embodiment shown in FIG. 5 has projecting edge portions 4 and 4 continuous on both side edges extending from the main body portion 1 to the suspension bolt mounting portion 2 as in the first embodiment. The upper portion 31 of the front wall portion 3a of the edge holder 3 is bent into a substantially U shape when viewed from the side, and has retaining protrusions 5 and 5 that protrude obliquely downward inward on the left and right sides thereof. However, it differs from 1st embodiment by the point which has the expansion | blocking prevention means of the field edge receiving holding part 3 further. The spread prevention means includes a T-shaped hooking piece 7 formed by punching on the upper side of the main body 1 and having a lower end connected to the main body 1, and an upper portion 31 of the front wall portion 3 a of the field edge holder 3. And a latch groove 8 that opens upward in the center of the frame, and bends the latch piece 7 forward, and engages the latch groove 8 with the tip latch portion 7a, thereby holding the edge receiving The portion 3 can be prevented from spreading outward. The hooking piece 7 is arranged so as to protrude forward from the vertically rectangular punching hole 1a so that a tool such as a screwdriver can be easily hooked at the time of bending, and prevents the base end position from being cracked by bending. For this purpose, the base 7b is bent backwards in a U-shape.

  When using this hanging metal fitting H3, as shown in FIG. 6, after holding the field edge receiver D in the field edge receiver holding part 3, the hanging piece 7 in the state of the phantom line shown in the figure is attached. A suitable tool such as a screwdriver is used to bend forward, and the leading end latching portion 7a is engaged with the latching groove 8 of the front wall portion 3a as shown by the solid line in the figure. As a result, the hanging metal fitting H3 does not expand the edge receiving portion 3 due to load or expand due to an external force such as an earthquake, and high load resistance and excellent durability can be obtained.

  The means for preventing the spread of the field edge holding portion 3 is not limited to the latching method constituted by the latching piece 7 and the latching groove 8 as in the third embodiment, and various methods can be adopted. For example, in the hanging metal fitting H4 of the fourth embodiment shown in FIG. 7, the projecting edge portions 4, 4 that are continuous to both side edges extending from the main body portion 1 to the suspension bolt mounting portion 2 are provided as in the first to third embodiments. However, a bolt insertion hole 33 is formed in the upper portion 31 of the front wall portion 3 a of the field edge holding portion 3, and the body portion 1 has substantially the same height as the bolt insertion hole 33. A screw hole 10 is formed, and the connecting bolt 9 inserted into the bolt insertion hole 33 from the front is screwed into the screw hole 10.

  In this hanging metal fitting H4, as shown in FIG. 7, after the field edge holder D is held by the field edge holder holding part 3, the front wall part 3a of the field edge holder holding part 3 and the main body part. 1 is connected with the connecting bolt 9 to prevent the field edge holder 3 from being expanded by load or expanded by an external force such as an earthquake. Can also be prevented. Therefore, the connecting bolt 9 in the hanging metal fitting H4 serves both as a means for preventing the spread of the field edge holding portion 3 and a means for preventing the separation of the field edge receiver D.

  The hanging bracket for the ceiling edge receiver of the present invention is not limited to those exemplified in the first to fourth embodiments, but the shape of each part, the shape and structure of the above-described detachment prevention means and spread prevention means, etc. The detailed configuration can be variously modified in addition to the embodiment.
