Description

  The present invention relates to a tightly bound hardware having earthquake resistance that does not cause slipping at the intersection between a field edge and a field edge when vibration such as an earthquake occurs.

  After the Great East Japan Earthquake, more earthquake-resistant ceiling structures are required. As means for fixing the field edge to the field edge holder in the conventional ceiling foundation structure, there are clips disclosed in Patent Document 1 and Non-Patent Document 1. However, each clip has a pair of claw parts formed at the lower end hooked on the lip of the field edge and locked, and the upper edge of the clip is bent and hooked on the field edge holder to make the field edge a field edge receiver. Since it is a fixed structure, if there is a deformation or breakage such as opening of the claw or lip due to vibration during an earthquake, the field edge will be easily removed from the field edge holder. Moreover, it was the structure where a field edge and a field edge holder slide with respect to a vibration of a horizontal direction.

  As fixtures having earthquake resistance in the vertical direction, there are structures shown in Patent Document 2 and Patent Document 3. Each of these fixtures has a configuration in which the upper portion is fixed to a field edge holder, and the field edge is inserted into the field edge support portion. As a result, the floating of the field edge with respect to the vibration in the vertical direction and the slip of the field receiver with respect to the vibration in the lateral direction are prevented. However, the field edge itself is a structure that is slidably held, and when lateral vibration occurs, the field edge moves in the axial direction, causing slipping at the intersection between the field edge and the field edge receiver, The earthquake resistance is not enough. Furthermore, in the hanging metal fittings of Patent Document 3, unevenness occurs in the ceiling finish material fixed under the field edge due to the thickness of the clip that is rotated under the field edge, so that the smoothness of the ceiling part looking up from the room is obtained. Damaged.

  The earthquake-proof reinforcement metal fitting disclosed in Patent Document 4 firmly fixes the intersection between the field edge and the field edge receiver. A first metal fitting which is arranged so as to straddle the field edge and is fitted to the field edge, and a second metal fitting which is disposed so as to sandwich the lip portion of the field edge and straddle the first metal fitting is attached to the field edge Since both metal fittings can be displaced in the axial direction of both the field edge and the field edge respectively, the structure is configured to absorb the impact force caused by the earthquake. In order to increase the seismic strength, it is necessary to attach reinforcing brackets to more places, but increasing the number of parts increases costs and labor, and increasing the weight increases the burden on other members. become.

  The clip disclosed in Patent Document 5 has the same structure as the clip disclosed in Patent Document 1 and Non-Patent Document 1, but is liquid in the contact portion of the field edge and the clip and the contact portion of the field edge and the clip. Alternatively, by applying or injecting a viscous adhesive, slipping at the intersection between the field edge and the field edge holder is suppressed. However, there is a limit to the strength of fixing with an adhesive.

  In the present invention, even when the Great East Japan Earthquake-grade vibration occurs, it is seismically resistant to vertical and lateral vibrations by suppressing slipping between the field edge and the field edge intersection. An object of the present invention is to provide a fastened hanging hardware that is easy to install and is inexpensive to prevent dropping.

  The problem of the present invention is that a tightly-suspended hardware is formed with a field edge receiving and locking part at the upper part of the trunk part extending in the longitudinal direction and a field edge holding part at the lower part. A single steel plate having a holding portion, wherein the bending engagement piece of the field edge receiving and engaging portion is bent and engaged from the outside of the upper flange of the field edge receiving portion into the opening, and is continued from the field edge receiving and engaging portion. The part is bent along the web part from the upper flange of the field receiver and fixed to the web part, and the pair of claw parts of the field edge holding part are hooked and locked to the lip part of the field edge and the field edge The above-mentioned holding part, which is a tightly-fitting hardware for fixing the bridge and which is valley-folded so as to be perpendicular to the field receiving web part, reaches the lower part of the field edge from the upper end of the field receiver and extends the field edge from its side surface. It is solved by being configured when fixed.

  It is more advantageous to attach a rib portion to the upper portion of the holding portion because the buckling portion is prevented from buckling and deformation of the tightly suspended hardware can be suppressed.

  If a hole smaller than the screw diameter to be fastened in advance is provided at the place to be screwed, the work becomes easier and proper tightening is possible, and tightening by screwing requires fewer parts and is also inexpensive. This is more advantageous because the overall weight can be kept light.

  According to the invention of claim 1, a field edge receiving and locking part is formed at the upper part of the trunk part extending in the longitudinal direction, and a field edge holding part is formed at the lower part, and the pair of refrigeration branches off from the trunk part and descends diagonally to the left and right. A single steel plate having a portion, wherein a bending engagement piece of the field edge receiving and engaging portion is bent and engaged in the opening from the outside of the upper flange of the field edge receiving portion, and the body portion continuing from the field edge receiving and engaging portion The upper edge flange of the field edge holder is bent along the web part and fixed to the web part, and the pair of claw parts of the field edge holding part are hooked and locked to the lip part of the field edge and the field edge and the field edge receiver As a result, the above-mentioned holding part that is valley-folded so as to be perpendicular to the field edge receiving web part reaches the lower edge of the field edge and fixes the field edge from its side. In addition, the rising of the field edge against the vertical vibration is prevented, and the field edge is received against the horizontal vibration. Because each sliding in the axial direction of the ceiling joist can be suppressed, preventing the slippage of the intersection is ensured. Moreover, even if there is deformation or breakage such as opening of the claw or lip due to vibration, the fall of the field edge can be prevented.

  According to the second aspect of the present invention, when the rib portion is attached to the upper portion of the holding portion, the buckling portion is prevented from buckling, so that deformation of the tightly bound hardware can be suppressed.

  According to the invention of claim 3, if a hole smaller than the screw diameter to be fastened in advance is provided at the place to be fastened with screws, the work becomes easier and proper fastening is possible. The cost is low because it is small, and the overall weight can be kept light.

The tightly-suspended hardware A, which is a single steel plate, has a field edge receiving and locking part 3c at the upper part and a field edge holding part 3a at the lower part. It consists of a set of holding parts 4 to get off. The steel plate used for the tight hanging hardware A is preferably thicker than the conventional JIS clip having a thickness of 0.6 mm in order to effectively bind the edge 2 and the edge receiver 1.

  The above-mentioned field edge receiving and locking portion 3c has a bent locking piece 3d and a notch 3e. In order to facilitate bending and locking, the base of the bending locking piece 3d is slightly narrower than the tip, and when there are two or more pieces, each is formed with a slight inclination toward the notch 3e as a whole. It is preferred that The bending locking piece 3d is bent and locked from the outside of the upper flange portion 1a of the field receiver 1 into the opening 1c. Depending on the length of the upper flange portion 1a of the field receiver 1, it can be bent and locked at any location of the bending locking piece 3d. Stopping is effective. The body part 3 continuing from the field edge receiving and engaging part 3c is bent along the web part 1b from the upper flange 1a of the field edge receiver and fixed to the web part 1b. As a result, it is possible to prevent the edge receiver 1 from sliding in the axial direction (Y direction in the figure) against vibrations in the vertical direction (Z direction in the figure) and lateral vibrations. The field edge holding part 3a has a pair of claw parts 3b. The claw portions 3b are hooked and locked to lips 2b provided on the left and right sides of the groove opening 2a of the field edge 2, respectively. It is desirable that the portion where the holding portion 4 starts to branch from the trunk portion 3 is a corner formed by the upper flange portion 1a and the web portion 1b of the edge receiving portion. This is to make the binding between the field and the field reception effective. Each set of holding portions 4 is provided with a rib portion 4a at the upper end thereof. The holding portion 4 is valley-folded so as to be perpendicular to the field edge receiving web portion 1b, reaches the lower edge of the field edge from the upper end of the field edge support, and is fixed to the field edge side surface portion 2c. Thereby, it is suppressed that the field edge 2 slides to an axial direction (X direction in a figure) with respect to the vibration to a horizontal direction. When a strong seismic force is applied, the buckling prevention rib portion 4a for preventing the hanging hardware from being deformed is mountain-folded so as to open to the outside so as to hit the edge receiver 1.

FIG. The bending locking piece 3d is bent and locked from the outside of the upper flange portion 1a of the field receiver 1 into the opening 1c. The body part 3 continuing from the field edge receiving / holding part 3c is bent along the web part 1b from the upper flange 1a of the field edge receiver, and fixed to the web part 1b with screws. The pair of claw portions 3b are hooked and locked to the lip portions 2b provided on the left and right sides of the groove opening 2a of the field edge 2, respectively. The pair of holding portions 4 branched from the trunk portion 3 at the corners formed by the upper flange portion 1a and the web portion 1b of the field edge receiver are each folded in a valley so as to be perpendicular to the field edge reception web portion 1b. The upper edge of the edge reaches the lower edge of the edge and is fixed to the edge edge side surface 2c with screws. The rib portion 4a is folded in a mountain so as to open to the outer edge receiver 1 so as to prevent buckling to prevent the hanging hardware from being deformed even when a strong seismic force is applied.

  Each of the screws 6a to 6f penetrates from the outside of the field edge 2 and the field edge receiver 1 into the respective openings 1c and 2a. The number of screws for fixing the field edge 2 and the field edge receiver 1 is not limited to the illustrated example, and may be one or three or more according to the size of the screw. It is desirable that at least two left and right heads are at least two for secure fixing. It is preferable to provide small holes 5a to 5f in advance at the place to be screwed. The hole is smaller than the screw diameter. In the holding portion 4, the screw holes 5 c facing each other on the left and right sides are arranged so that the tips of the screws penetrating according to the width H in the short direction (Y direction in the drawing) of the field edge 2 do not collide with each other in the opening of the field edge. It is desirable that the positions of 5e, 5d, and 5f are shifted to be left-right asymmetric.

  According to the present invention, by suppressing slipping between the field edge and the field edge receiving intersection, the field edge can be prevented from falling due to vertical and horizontal vibrations such as earthquakes, and the earthquake resistance of the ceiling structure is improved.
