Description

  The present invention relates to a thin-plate type field edge mounting bracket for assembling and fixing a field edge in a ceiling base to a field edge receiver, and a field edge mounting method.

In general, a conventional ceiling is supported by a plurality of field receivers (channel materials) supported by the frame ceiling through suspension members (suspending bolts, suspension wires, etc.) and a field receiver through field attachment brackets. A plurality of channel-shaped field edges and a ceiling panel screwed to the field edges.
The edge mounting brackets are mainly press-molded with a thick plate material with a plate thickness of about 1.6 mm that cannot be deformed with acupressure on the ceiling base of buildings where earthquake resistance is required in advance. For the ceiling base, a press-molded thin plate material having a plate thickness of about 0.6 mm is employed (see Patent Document 1, FIG. 8, and Patent Document 2, FIG. 1, FIG. 4). .

  Conventionally, as shown in FIG. 4, the thin plate type field edge mounting bracket 9 is placed on the upper surface of the field edge receiver 4, and a latching piece 911 formed with a length projecting from the field edge receiver. And a hanging piece 912 that is brought into contact with the rising surface of the field edge receiver 4 from the retaining piece 911, and is attached by folding the front end side of the retaining piece 911 into the back surface side of the field edge receiver 4. A pair of receiving pieces 921 inserted into the inverted U-shaped groove 71 at both ends thereof, with the L-shaped field edge receiving attachment portion 91 and the lower end of the hanging piece 912 extended into the field edge receiving 4. It is integrally formed by the field edge support receiving part 92 which has.

However, this is a shiatsu-deformable thin plate material that can be folded by folding the tip end of the latching piece 911 by hand with respect to the field receiver 4, so that it can be folded by shiatsu due to shaking such as an earthquake. The metal fitting itself such as the latching piece 911 and the receiving piece 921 is easily deformed, and in particular, the receiving piece 921 is loosely inserted into the inverted U-shaped groove 71 by being bent by the latching piece 911 only on the upper side. Therefore, when the receiving piece 921 is subjected to a vertical swinging load, a concentrated load that is in the upper dynamic pressure contact with the inverted U-shaped groove 71 is applied to deform the deformation. The vibration (tilting) in the downward direction away from the inverted U-shaped groove 71 causes backlash between the field edge 7 and the field edge receiver 4, and a positional deviation occurs between the two. If further vibrations are received in various states, resonance will occur. The shaking is amplified and the rattle and position shift increase, and it deforms to the extent that it cannot be supported by the field edge 7. The joint strength as well as the seismic strength is extremely inferior, and the entire ceiling base is distorted. In such a suspension structure that only causes the field edge 7 to be supported and received by such a field edge support receiving portion 92, the desired seismic performance cannot be obtained regardless of the thickness of the plate material. There is a problem.

On the upper side of the field edge regulating pieces 513 and 513, a guide part 514 is formed so as to be opposed to each other and inclined in an inverted C shape so as to guide and insert the field edge 7 into the field edge fitted part 51. A screw hole 6 a for fixing a screw to the lower surface of the field edge 7 is formed in the field edge lower surface piece 511 slightly outside the portion substantially facing the field edge regulating piece 513.

When the field edge 7 is set by inserting and guiding the field edge 7 into the field edge fitted part 51 via the guide part 514, the field edge side pieces 512 and 512 are expanded, and the Temporarily assembled state in which the field edge regulating pieces 513 and 513 are elastically returned to and engaged with the upper surfaces of the inverted U-shaped grooves 71 and 71 (so-called patching) and the field edge 7 is prevented from coming off. Can be done.
Moreover, the upper half part of the field edge side piece 512 has a function as a reinforcing surface part and a function as a grip part at the time of attachment work of the field edge 7 by gripping the upper half parts. When the lower half of the field edge side piece 512 is slightly separated from the side surface of the field edge 7 in a state in which 7 is inserted and set in the field edge fitted portion 51, the upper half of the field edge side piece 512 is By sandwiching the parts and narrowing the pressure on both side surfaces of the field edge 7, it is possible to correct the state to be in close contact with an appropriate interval.

  The field edge receiving portion 52 is bent toward the outside (on both sides of the field edge 7) from the upper half of the field edge side piece 512, and is contacted and engaged with the rising surface of the field edge receiver 4. The receiving engagement piece 521 is bent from the upper and lower ends of the field edge receiving engagement piece 521 so as to sandwich the upper surface and the lower surface of the field edge receiving 4, and protrudes beyond the width surface of the field edge receiving 4 at the tip side. Are formed in a substantially U-shape in a lateral direction that opens in a direction opposite to the field edge fitting portion 51, and the field edge receiving engagement pieces 521, 521 of the field edge receiving engagement pieces 521, 521. A pair of field edge receiving fixing pieces 523 which are formed to bend toward the field edge fitted part 51 side away from the upper half part of the field edge side piece 512 from the opposite side, and the rising surfaces face each other. 523 are provided.

  The upper field edge holding piece 522 is closer to the side surface of the field edge 7, and the lower field edge holding piece 522 is separated from the side surface of the field edge 7 (position separated from the reinforcing portion 53) And the lower side edge receiving sandwiching pieces 522, 522 are arranged to face each other (facing each other) in a state of being misaligned. When the misalignment is arranged in this way, when the distal end portion of the lower field edge holding piece 522 disposed away from the side surface of the field edge 7 is bent to the back side of the field edge receiver 4, The field edge 7 does not get in the way, the bending operation can be easily performed, and the field edge receiver 4 can be held in a diagonal plane with a different phase angle, so that the joint strength against the swing restriction can be improved. it can.

In this temporarily assembled state, when the lower half of the field edge side piece 512 is slightly separated from the side surface of the field edge 7, the upper half parts of the field edge side piece 512 that also serves as a gripping part Is tightly corrected at an appropriate interval by narrowing pressure on both side surfaces of the field edge 7.

  Next, the respective top ends of the four top and bottom field receiving pinching pieces 522... Projecting from the upper and lower surfaces of the field receiving 4 are bent and attached to the back side of the field receiving 4 in a V shape or U shape. When this bending operation is performed, if the hand is released from the state where the upper half of the field edge side piece 512 is gripped, the state where the lower half of the field edge side piece 512 is closely corrected to both side surfaces of the field edge 7 is Since it may return to the slightly separated state again, it is preferable to perform the folding operation while maintaining the gripping state. In addition, the priority order of the bending operation of the front end portion of each field edge holding piece 522 is not particularly limited, but if the upper field edge holding pieces 522 and 522 are bent first, the above-mentioned close contact Since the corrected state is maintained, it is possible to perform the bending operation of the lower edge receiving pinch pieces 522 and 522 even if the hand is released.

After that, the standing edge receiving edge fixing pieces 523 and 523 are bent to a lying position, are brought into pressure contact with the rising surface of the field receiving edge 4 and polymerized, and the field holes are formed through the overlapping screw holes 6b and 6b. If the screw is fixed to the rising surface of the edge receiver 4 and the field edge lower surface piece 511 is fixed to the lower surface of the field edge 7 through the screw hole 6a, the mounting is completed.
In this way, when the field edge receiving fixing pieces 523 and 523 and the field edge lower surface piece 511 are fixed by screws, the field edge fitting part 51 and the field edge receiving attachment parts 52 and 52 are respectively connected to the field edge receiver 4. It is tightly integrated with the three-piece fit with respect to the field edge 7, and the synergistic fixing action of these three members increases the strength of assembly rigidity and further improves the seismic strength against displacement and deformation due to vibration. Can be achieved.

  In the embodiment of the present invention configured as described above, the field edge 7 is attached to the field edge receiver 4 via the field edge mounting bracket 5 in the construction on the base of the ceiling portion 1. The field edge mounting bracket 5 is fitted on the lower surface and both side surfaces of the field edge 7, and the upper end side thereof has an upper half portion (field edge side piece 512) extending upward from the field edge 7. The field-shaped fitted portion 51 is fitted on both sides of the upper half and on the rising surface and the upper and lower surfaces of the field-receiver 4 that is outside the field edge 7, and the field-edge fitted so as to be opposed to each other.

The field edge fitting part 51 is inserted from the lower surface side of the field edge 7 through the field edge receiving fixing pieces 523 and 523, and the field edge receiver mounting part 52 is brought into contact with the rising surface of the field edge receiver. In this fitted state, each tip side protruding from the field edge receiver 4 of the field edge holder clamping pieces 522, 522 is pressed and bent to the back surface side of the field edge receiver 4, and a pair of By pressing and bending the field edge receiving fixing pieces 523 and 523 to face each other with respect to the rising surface of the field receiving edge 4, the field edge receiving fixing pieces 523 and 523 to be overlapped are fixed by screws. The edge 7 is fitted to the edge fitting portion 51, and the outer peripheral surface side should be supported and received. Configure and Aru.

  If comprised in this way, although it is the field attachment bracket 5 which is a thin-sheet material and can be affixed to the finger, it is hooked to the field receiver 4 by pressing and bending only the upper surface side to the back surface side. The conventional structure for intensively supporting and receiving the field edge 7 from the inside is eliminated by the field edge receiving attachment part 91 and the field edge support receiving part 92 loosely inserted into the inverted U-shaped groove 71 of the field edge 7. Wide overlapping of the pair of field edge receiving attachment parts 52, 52 and the field edge fitting part 51 covering the outer peripheral surface area which is the three surfaces of the field edge receiver 4 and the field edge 7, respectively. Since it has a surface area and can be firmly integrated and attached in a state in which both are fitted, the strength of assembly rigidity is increased, and the field edge 7 is supported and received by the field edge fitting part 51 from its lower surface side. Depending on the structure, it can be mounted with improved support receiving strength that does not apply concentrated load. In addition, the field edge mounting portions 52, 52 that form a pair are securely clamped and attached by the field edge holder clamping pieces 522 that are pressed and bent at four positions on the back side of the field edge receiver 4, and Since the field edge receiving fixing pieces 523 to be superposed are screw-fixed, the joint strength between the three parties can be improved.

  As a result, when receiving a shake such as an earthquake, the pair of field edge mounting portions 52, 52 do not expand, and the rocking load is generated by the outer periphery of the field edge receiver 4 and the field edge 7. With a wide overlapping surface area covering the surface, the stress can be received in a dispersed state, and it can be prevented from being concentrated and applied to each part of the field mounting bracket 5 to prevent deformation. The swing regulation in the width direction so as to be separated from 7 is surely improved, and the swing regulation in the longitudinal direction is also fixed to the lower surface of the field edge 7 by screws or the field regulation piece 513.

Since the upper half portion is formed by the field edge side pieces 512 and 512 having a length extending above the field edge 7, the field edge receivers are provided on the upper half portions of the field edge side pieces 512 and 512. The mounting portion 52 and the field edge regulating piece 513 can be bent, and the upper half functions as a gripping portion, even if the lower half of the field edge side piece 512 is slightly separated from both side surfaces of the field edge 7 again. Even in this state, the upper half can be sandwiched between the two sides of the field edge 7 so that the pressure can be reduced and brought into close contact with each other. Each tip of the pieces 522 can be bent into a V-shape on the back side of the field edge receiver 4.

It is arranged on the outside so as to face the positional deviation. When the misalignment is arranged in this manner, the field edge receiving attachment portion 52 can be firmly attached to the field edge receiver 4 by the field edge receiving clamping pieces 522. When the front end of the edge holder 522 is bent to the back side of the field receiver 4, the field edge 7 does not get in the way and the bending operation can be easily performed. Since it can be held in a diagonal plane with a different phase angle, the joint strength against rocking regulation can be improved.

  Further, the upper half of each of the field edge side pieces 512 and 512 is engaged with the upper surface of the inverted U-shaped groove 71 on the side opposite to the field edge receiver 4 to restrict the tilt of the field edge 7. Since the field edge regulating pieces 513 and 513 formed toward the width inside (width direction) of the field edge 7 are provided, the field edge lower surface piece 511 is provided with the field edge 7 when subjected to shaking such as an earthquake.

  In addition, the field edge regulating pieces 513 and 513 are configured to form a guide part 514 that is inclined in an inverted C shape above the field edge restricting pieces 513 and 513 so that the field edge 7 is inserted and guided to the field edge fitted part 51. For this reason, when the field edge 7 is inserted and guided in the field edge fitting part 51 and set, the field edge side pieces 512 and 512 are expanded, and with the resilience, the field edge regulating pieces 513 and 513. Can be elastically restored and engaged with the upper surfaces of the inverted U-shaped grooves 71, 71, and the field edge 7 can be prevented from coming off with one touch, and the field edge mounting bracket 5 is slid from this state. Thus, it is possible to obtain a temporarily assembled state simply by fitting the field edge receiver mounting portion 52 to the field edge receiver 4, so that the attachment work can be easily performed and the work efficiency can be improved.

Further, the field edge lower surface piece 511 is formed at a lower surface portion of the field edge 7 that is separated from the field edge receiver 4, that is, a screw hole 6a that is formed in a region that is substantially opposed to the field edge regulating piece 513 (slightly outside). Since the screw is fixed to the lower surface of the field edge 7 at the portion, the field edge 7 and the field edge fitted portion 51 can be fixed and attached while being supported by the field edge 7. The edge fitting part 51 and the field edge receiving attachment parts 52, 52 are firmly integrated in a three-piece integrated state with respect to the field edge receiver 4 and the field edge 7, respectively, and these three are fixed together. As a result, not only can the strength of the assembling rigidity be improved, but the joint action with the field edge regulating pieces 513 and 513 can further improve the rocking regulation in which the field edge lower surface piece 511 is separated from the field edge 7. Such as the occurrence of rattling between the field edge 7 and the field edge receiver 4, the field edge mounting bracket 5, etc. The location shift is reliably prevented, thereby improving the earthquake resistance.
