Description

  The present invention relates to a ceiling brace mounting bracket for attaching a ceiling brace spanned between a ceiling base material assembled in a lattice pattern on the back of the ceiling and an upper end side of a suspension bolt for suspending the ceiling base material to the ceiling base material. .

  Conventionally, a ceiling bolt that is suspended from an upper floor slab or roof slab and suspended from a ceiling structural frame, which is a ceiling base material composed of a main bar and a cross bar, assembled in a grid pattern. There is known a suspended ceiling constructed by hanging and supporting at the lower end of the hanger via a hanging hanger (suspended metal fitting) (see, for example, Patent Document 1 and Patent Document 2).

  In such a suspended ceiling, in order to improve seismic resistance, the lower end of the suspension bolt located immediately above the connecting intersection of the main bar and the crossbar, and the upper end of another suspension bolt adjacent to the suspension bolt A ceiling brace was installed between the two parts. This ceiling brace was fixed to the side surface of the suspension bolt by welding. This is because the hanging hanger is formed by bending a narrow band-shaped plate material, and a ceiling brace cannot be attached to the hanging hanger. In such a configuration, there is a problem in that the suspension hanger swings around the connection position of the suspension hanger to the suspension bolt below the suspension bolt to which the ceiling brace is connected.

  Therefore, the present applicant created a reinforcing metal fitting shown in Patent Document 3 and attached the hanger so as to cover the hanger, thereby preventing the hanger from shaking. The reinforcing bracket includes a reinforcing surface portion that is formed in a range from the mounting portion or the vicinity thereof to the ceiling base material, and is attached to be attached along the ceiling base material. A ceiling brace is attached to the reinforcing surface portion. Configured to connect.

  By the way, after hanging bolts are suspended at the construction site, the ceiling foundation material is assembled in a grid pattern, but the hanging position of the suspension bolts and the connecting intersection of the main bar and crossbar of the ceiling foundation material are shifted. If this happens, there is a risk that the improvement in seismic performance due to the ceiling brace will be reduced. Therefore, in the past, the position was corrected by hitting the suspension bolt to the upper floor slab or roof slab. However, when the suspension bolt was re-applied to the upper floor slab, the upper floor slab and the suspension bolt In some construction sites, re-joining is prohibited because the strength of the joint decreases.

  Therefore, the present invention has been made to solve the above-described problem, and even if the hanging position of the suspension bolt is shifted, the ceiling brace can sufficiently improve the earthquake resistance performance. It is an object to provide a brace mounting bracket.

Therefore, since the lower end side of the ceiling brace can be attached to the connecting intersection of the ceiling base material, it is possible to sufficiently improve the seismic performance by the ceiling brace.

  According to the present invention, the brace fixing bracket includes both the main parallel part and the cross parallel part, and the main parallel part and the cross parallel part are formed separately, and the main parallel part And the cross parallel portion are configured to be detachable from each other.

  According to such a configuration, both the ceiling brace extending along the longitudinal direction of the main bar and the ceiling brace extending along the longitudinal direction of the cross bar are integrally attached to one connecting intersection. Can do. Further, when the ceiling brace is unidirectional, an unnecessary main parallel part or cross parallel part can be detached, and weight reduction can be achieved.

  Further, the present invention provides a main bar fixing portion which is located at a lower end portion of the main parallel portion and is fixed to an upper edge portion of the main bar, on both sides of the connecting intersection portion when viewed in the longitudinal direction of the main bar. It is characterized by being formed respectively.

  According to such a configuration, since the brace fixing bracket and the ceiling base material can be connected to each other in the longitudinal direction of the main bar across the connecting intersection, the ceiling brace and the ceiling base material can be connected in a balanced manner. The earthquake resistance can be further improved.

  Further, the present invention provides a crossbar fixing portion that is located at a lower end portion of the cross parallel portion and is fixed to an upper edge portion of the crossbar, as viewed in the longitudinal direction of the crossbar. It is characterized by being formed respectively.

  According to such a configuration, since the brace fixing bracket and the ceiling base material can be connected to each other in the longitudinal direction of the cross bar across the connecting intersection, the ceiling brace and the ceiling base material can be connected in a balanced manner. The earthquake resistance can be further improved.

  Further, the present invention is characterized in that the brace fixing bracket includes an accommodating portion for accommodating a hanging hanger that supports the ceiling base material.

In addition, as shown in FIG. 11, when arrange | positioning so that the plate | board surface width direction of the hanging hanger 20 may become parallel with respect to the surface direction of the brace fixed surface part 56 which mentions the 1st member 53 later, a 1st member 53 is parallel to the hanging hanger 20 that sandwiches the main bar 2, so that the main bar 2 is sandwiched and becomes the main parallel part 51. Then, the second member 54 orthogonal to the first member 53 sandwiches the cross bar 3 and becomes the cross parallel part 52.

  The first member 53 is a member connected to the hanging hanger 20 when the hanging hanger 20 is located at the connecting intersection 8 (see FIGS. 5 to 7). The first member 53 is integrally formed by punching or bending a metal plate having a desired thickness that is excellent in rigidity and corrosion resistance. In the present embodiment, the first member 53 forms a cross parallel portion 52 and is disposed along the cross bar 3. The first member 53 includes an engaging portion 55 that is horizontally disposed on the upper end side, and a brace fixing surface portion 56 that is formed by being bent substantially vertically from the engaging portion 55.

  The locking portion 55 is connected in a substantially neck shape with an appropriate inclination angle and a plate width (equivalent to the plate width of the metal fitting body 22 of the hanging hanger 20) from the central portion of the brace fixing surface portion 56 in the plate width direction. It is formed by bending the upper end side of the installation part 57 horizontally. The continuous portion 57 is formed with a through hole 57 a through which a screw for fixing the first member 53 and the second member 54 is inserted. The locking portion 55 is formed with a notch portion 55a formed in a plane U shape from the front end edge side. The notch 55a is a place where the bolt 26a is inserted, and the engaging portion 55 and the mounting portion 25 of the hanging hanger 20 are sandwiched from above and below by a pair of nuts 26b and 26b screwed into the bolt 26a. Thus, the first member 53 is fixed to the hanging hanger 20 (see FIGS. 6 and 7). That is, the space below the locking portion 55 constitutes a housing portion 20 a that houses the hanging hanger 20.

  The brace fixing surface portion 56 is disposed on both sides in the width direction of the continuous portion 57 and includes a flat portion 56a with which the side surface of the ceiling brace 9 abuts. The brace fixing surface portion 56 is formed with a gap 60 having a predetermined width with respect to the connecting portion 57, and the engaging portion 62 of the second member 54 is inserted into the gap 60, so that the first member 53 and the first member 53 are connected to each other. The two members 54 are engaged (see FIGS. 4 and 5). As shown in FIGS. 4, 5, and 7, on the lower end side of the brace fixing surface portion 56, the convex surface shape (main bar 2) of the upper edge 3 a (see FIG. 3) of the crossbar 3 (see FIG. 3). The support part (crossbar fixing | fixed part) 58 formed in the concave shape along the upper edge part 2a is also the same shape. A screw hole 58 a is formed in the support portion 58. Then, the brace fixing surface portion is formed by screwing the screw V from the support portion 58 side to the crossbar 3 by placing the support portion 58 along the crossbar 3 toward the upper edge portion 3a. The crossbar 3 is fixed to 56. Further, the first member 53 is formed such that the flat portions 56a on both sides in the plate width direction of the brace fixing surface portion 56 extend downward, straddling the main bar 2, and the support portions 58, 58 are crossbars 3, 3 are respectively addressed to the upper edge portions 3a and 3a. The fixing of the support portion 58 and the cross bar 3 is not limited to the above-described structure, and for example, the upper edge portion 3a of the cross bar 3 may be sandwiched like the hanging hanger 20. Reinforcing ribs 61 are respectively formed at the ends in the width direction of the flat portion 56a. The reinforcing rib 61 is formed by bending the plate material of the first member 53 in a right angle direction.

  As shown in FIGS. 1 and 2, the second member 54 is a member connected to the first member 53, and is punched into a metal plate having a desired plate thickness excellent in rigidity and corrosion resistance. And are integrally formed by bending. In this embodiment, the 2nd member 54 comprises the main parallel part 51, and is arrange | positioned along the main bar 2 (refer FIG. 3). The second member 54 includes an engaging portion 62 that engages with the first member 53 and a brace fixing surface portion 63 that is located on both sides of the engaging portion 62 in the plate thickness direction.

  As shown in FIGS. 4 and 5, the engaging portion 62 is a portion that is inserted into the gap 60 between the brace fixing surface portion 56 and the connecting portion 57 of the first member 53. It is formed in a U shape in plan view so as to surround the portion 55 (the housing portion 20a of the hanging hanger 20). As for the engaging part 62, while the lower end part contact | abuts to the lower end part of the clearance gap 60 of the 1st member 53, an inner peripheral surface contact | abuts to the surface of the connection part 57, and the outer peripheral part of the latching | locking part 55, Engaged with the first member 53. Further, a through hole 62 a is formed on the side surface of the engaging portion 62, and a screw (not shown) is held from the through hole 62 a toward the through hole 57 a of the connecting portion 57 of the first member 53. Thus, the first member 53 and the second member 54 are fixed.

  As shown in FIGS. 1 and 2, the brace fixing surface portion 63 is disposed on both sides of the engaging portion 62 in the width direction. The brace fixing surface portion 63 is formed by bending the plate members at both end portions of the engaging portion 62 outward in a right angle direction. The brace fixing surface portion 63 includes a flat surface portion 63a with which the side surface of the ceiling brace 9 (see FIG. 3) abuts, and the flat surface portions 63a and 63a are configured to be located on the same plane. The brace fixing surface portion 63 extends downward from the lower end portion of the engaging portion 62 and is formed in a bifurcated shape, and is configured to straddle the cross bar 3 and the first member 53. As shown in FIGS. 4 to 6, the lower end side of the brace fixing surface portion 63 is formed in a concave shape along the convex surface shape of the upper edge 2 a (see FIG. 3) of the main bar 2 (see FIG. 3). Further, a support portion (main bar fixing portion) 64 is formed. A screw hole 64 a is formed in the support portion 64. Then, the support portion 64 is routed along the main bar 2 to the upper edge portion 2a, and the screw V is held from the support portion 64 side to the main bar 2, so that the main bar 2 is placed on the brace fixing surface portion 63. Is fixed. Note that the fixing between the support portion 64 and the main bar 2 is not limited to the above structure, and for example, the upper edge portion 2a of the main bar 2 may be sandwiched like the hanging hanger 20. Reinforcing ribs 65 are respectively formed at the ends in the width direction of the flat portion 63a. The reinforcing rib 65 is formed by bending the plate material of the second member 54 in a right angle direction.

  The second member 54 is connected so that the brace fixing surface portion 63 is orthogonal to the brace fixing surface portion 56 of the first member 53, and the brace fixing bracket 50 has a substantially cross shape in plan view.

  According to the ceiling brace mounting bracket 1 having such a configuration, as shown in FIGS. 3 and 4, the installation position of the suspension bolt 5 is shifted from the connecting intersection 8 between the main bar 2 and the crossbar 3. Even if it exists, the ceiling brace 9 can be attached to the connection crossing part 8 without moving the suspension bolt 5 by directly fixing the brace fixing bracket 50 to the main bar 2 and the cross bar 3. At this time, even without the hanging hanger 20, the brace fixing bracket 50 is fixed to the main bar 2 and the crossbar 3 with sufficient strength via the support portions 58 and 64. As a result, the stress applied to the main bar 2 and the stress applied to the cross bar 3 during an earthquake can be efficiently transmitted to the ceiling brace 9, and local stress is not applied to the suspension bolt 5 and the suspension hanger 6, so that the rigidity Becomes higher, and buckling of each part can be suppressed. Therefore, it is possible to sufficiently improve the seismic performance by the ceiling brace 9.

  In the present embodiment, the brace fixing bracket 50 includes both the main parallel part 51 (second member 54) and the cross parallel part 52 (first member 53). Both the ceiling brace 9 that extends and the ceiling brace 9 that extends along the longitudinal direction of the cross bar 3 can be integrally attached to one connecting intersection 8, thereby further improving the seismic performance. be able to. Furthermore, by being able to attach the ceiling race 9 in the four directions in which the main bar 2 and the cross bar 3 extend from the connecting intersection 8, the brace installation position is limited due to the influence of ducts and equipment on the back of the ceiling. Even in this case, the braces can be arranged efficiently so as to be advantageous in terms of structure.

  Further, since the support portions (main bar fixing portions) 64 positioned at the lower end portion of the main parallel portion 51 are formed on both sides of the connection intersection portion 8 when viewed in the longitudinal direction of the main bar 2, the connection intersection portions are formed. The brace fixing bracket 50 and the main bar (ceiling base material) 2 can be connected with 8 interposed therebetween. Therefore, the ceiling brace 9 and the main bar 2 can be connected with a good balance, and the seismic performance can be further improved.

  Further, since the support portions (crossbar fixing portions) 58 positioned at the lower end portion of the cross parallel portion 52 are formed on both sides of the connecting intersection portion 8 when viewed in the longitudinal direction of the crossbar 3, the connecting intersection portions are formed. Since the brace fixing bracket 50 and the cross bar (ceiling base material) 3 can be connected with the 8 interposed therebetween, the ceiling brace 9 and the cross bar 3 can be connected in a well-balanced manner, and the earthquake resistance can be further improved. .

  Further, as shown in FIGS. 5 to 7, when the suspension bolt 5 is located at the connecting intersection 8, the brace fixing bracket 50 can be fixed to the existing suspension hanger 20, easily and reliably. The ceiling brace 9 can be fixed to the ceiling base materials 2 and 3.

  Further, in the present embodiment, the brace fixing bracket 50 is formed in a cross shape in plan view, but is not limited thereto. For example, it may be formed in a T shape in plan view. If it forms in such a shape, it will become possible to connect a ceiling brace in the connection crossing part of the peripheral part of a ceiling.

[Second Embodiment]
Next, a ceiling brace mounting bracket 1 ′ according to a second embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 8 to 10, in the ceiling brace mounting bracket 1 ′ according to the second embodiment, the brace fixing bracket 50 ′ includes only the first member 53 (cross parallel portion 52), and the second member Is not provided.

  That is, the ceiling brace mounting bracket 1 ′ according to the present embodiment is provided when connecting only the ceiling brace 9 (see FIG. 9) provided extending in the longitudinal direction of the crossbar 3. The first member 53 is provided in a direction orthogonal to the hanging hanger 20 that sandwiches the main bar 2 and is disposed along the cross bar 3.

  In addition, since the structure of the hanging hanger 20 and the 1st member 53 is the same as that of 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. In the present embodiment as well, the brace fixing surface portion 50 ′ can be directly fixed to the main bar 2 or the crossbar 3 even when the hanging hanger 20 is displaced from the connecting intersection 8.

  According to such a configuration, the following operational effects can be obtained in addition to the operational effects similar to those of the first embodiment. That is, when the first member 53 (cross parallel part 52) and the second member 54 (main parallel part 51) are detachable, when the ceiling brace 9 to be connected is unidirectional, an unnecessary main parallel part 51 is provided. Alternatively, the cross parallel part 52 (the second member 54 which is the main parallel part 51 in this embodiment) can be detached, and the number of parts of the brace fixing bracket 50 ′ can be reduced and the weight of the ceiling brace mounting bracket 1 ′ can be reduced. can do.

[Third embodiment]

As shown in FIG. 11, the ceiling brace mounting bracket 1 ″ according to the third embodiment is such that the plate surface width direction of the hanging hanger 20 is parallel to the surface direction of the brace fixing surface portion 56 of the first member 53. The first member 53 is parallel to the hanging hanger 20 that sandwiches the main bar 2. Therefore, the first member 53 sandwiches the main bar 2, and the main parallel part 51. Then, the support portion 58 on the lower end side of the first member 53 serves as a main bar fixing portion, while the second member 54 orthogonal to the first member 53 sandwiches the cross bar 3 so that the cross It becomes the parallel part 52. And the support part 64 of the lower end side of the 2nd member 54 becomes a crossbar fixing | fixed part.

[Other forms]
In the first embodiment and the second embodiment, the first member 53 is fixed to one of the main bar 2 and the cross bar 3, and the second member 54 is fixed to the other of the main bar 2 and the cross bar 3. The first member 53 and the second member 54 are arranged so as to be orthogonal to each other, but the shapes of the first member 53 and the second member 54 are not limited to this.

  For example, as shown in FIG. 12, the first member and the second member may be constituted by a pair of L-shaped members 70, 70, which may be fixed to a hanging hanger (not shown) as a brace fixing bracket 71. . The L-shaped member 70 is substantially L-shaped in plan view, and one side 70a is fixed to one side surface (right side in FIG. 12) of the main bar 2, and the other side 70b straddles the main bar 2. The main bar 2 is configured to extend to the other side surface (left side in FIG. 12) and to be fixed to the side surface of the cross bar 3 fixed to the other side surface. The other L-shaped member 70 is arranged so as to be point-symmetric with respect to the L-shaped member 70 around the connecting intersection 8, and one side 70 a is on the other side of the main bar 2 (in FIG. 12). The other side 70b extends across the main bar 2 and extends to one side surface (right side in FIG. 12) of the main bar 2 and is fixed to the side surface of the cross bar 3 fixed to one side surface. It is configured to be. Each L-shaped member 70 is fixed to each other by a known fixing means such as a screw. The L-shaped member 70 includes a main parallel portion connected to the main bar 2 and a cross parallel portion connected to the cross bar 3 as a single member. In addition, in FIG. 12, the schematic block diagram is shown and the structure which connects the hanging hanger and the L-shaped member 70 to this is abbreviate | omitting illustration.

  According to such a configuration, in addition to being able to obtain the same effects as those of the first embodiment and the third embodiment, if one of the L-shaped members is omitted, the corner of the corner of the ceiling It becomes possible to connect the ceiling brace.

  As mentioned above, although the form for implementing this invention was each demonstrated, this invention is not limited to the said embodiment, A design change, such as a material, a shape, and a magnitude | size, is suitably possible in the range which does not deviate from the meaning of this invention. It is. For example, in the embodiment, the shape of the hanging hanger 20 is the same as that of the existing hanging hanger 6. However, the shape is not limited to this, and may be other shapes, or may be formed integrally with the brace fixing bracket. It is good.

  Moreover, in the said embodiment, although the brace fixing metal fitting 50 is comprised by the 1st member 53 and the 2nd member 54 separately, it is not limited to this, A planar view cross shape or T-shape The shape may be integrally formed.
