Description

  The present invention relates to a connecting structure of a ceiling bracing reinforcing brace that forms a unitized system ceiling or the like that is framed in a lattice shape by a T-bar or the like.

  In general, in this type of unitized system ceiling structure, in order to improve the seismic strength by integrating the entire ceiling unit, the reinforcing brace is placed on the top side of the ceiling case between the suspension bolts suspended on the ceiling case. The base end side is installed on the side of the ceiling surface (T-bar) side, and is attached on the basis of an inclination angle of about 45 °.

  By the way, there is a conventional method of attaching the reinforcing brace, and depending on the construction, there is a portion where the reinforcing brace cannot be attached at an inclination angle of 45 ° due to the interval between the suspension bolts. Installation with an inclination angle of 15 ° is allowed. Therefore, as disclosed in Patent Document 1, a connecting piece (movable piece 15) is provided on the distal end side of the reinforcing brace (11), and the connecting piece and a hanging bracket (fixing tool 13) to the suspension bolt (3) are provided. Is known which is attached to a shaft (17) so that the angle of the reinforcing brace can be adjusted.

However, in this case, the connecting piece (movable piece 15) and the hanging fitting (fixing tool 13) are directly pivotally attached (17) to the position near the side of the suspension bolt (3). The fixing tool 13) becomes a free end and rotates more than necessary, and the nail piece (13b) can be directly hooked on the upper part of the suspension bolt (3) by holding the base end side of the reinforcing brace (11). Therefore, from the state in which the hook (fixing tool 13) is provided with a claw piece (13c) and the hook (fixing tool 13) is previously hooked on the lower side of the hanging bolt (3), the hanging bolt ( The work of moving to the upper side of 3) is forced, and it has the disadvantage that the work of latching is difficult and the work efficiency deteriorates. In addition, if it continues to be shaken by an earthquake or the like after construction, it will be pushed and pulled so that it can change beyond the construction allowable angle (allowable range that functions as a brace) of the reinforcing brace (11) with respect to the shaft attachment part. The load in the pulling direction and the load in the torsional direction are concentrated, and the dependence on seismic strength is concentrated on the hanging bracket (fixing tool 13), causing positional deviation and deformation in the hanging bracket, and the entire reinforcement structure As a result, there is a concern that the seismic balance will be lost and the durability will be impaired. Therefore, as disclosed in Patent Document 2, the bolt portion (51) is suspended by screwing into the hanging bracket (mounting bracket 6). There has been a demand for the emergence of a structure in which the reinforcing brace (5) can be disposed substantially on the axis of the bolt (2) and the angle can be adjusted even in a structure in which a load in the twisting direction is not applied.
In addition, the code | symbol attached | subjected with the said parenthesis () is the code | symbol used in the said gazette.

  The present invention has been devised to eliminate the above-mentioned problems, and the reinforcing brace and the hanging bracket are connected to each other through the connecting bracket so that the angle can be adjusted. During the installation work in an inclined manner, when the hanging bracket is hooked on the top of the suspension bolt, the hanging bracket is restricted from rotating more than necessary. It is possible to perform the same latching work as that using a simple connecting bracket and maintain the work efficiency as it is, and after construction, when it is shaken by an earthquake, etc., it is pushed and pulled (pushing / pulling) to the shaft mounting part. Even if a load is applied in the direction, it is possible to regulate the reinforcement brace from changing beyond its allowable construction angle. And to provide a connection structure of the ceiling foundation reinforcing brace can be maintained.

  The technical means adopted by the present invention to solve the above-mentioned problem is that a unit ceiling surface is formed by assembling a T bar or the like for laying a building panel via a plurality of suspension bolts suspended on a ceiling frame, A reinforcing brace attached between the suspension bolts in an inclined manner with the distal end side laid on the ceiling housing side and the proximal end side on the ceiling surface side, and the suspension bolt is connected to the distal end side of the reinforcement brace via a connecting fitting A hook that is hooked to the upper side of the hook is attached, and the connecting bracket includes a brace mounting portion that is attached to a reinforcing brace, and a nut portion that is provided facing substantially the axis of the hanging bolt of the hook. A bolt portion that can be screwed in at a predetermined inclination angle, and a plate-like tip portion of the brace mounting portion and a plate-like base portion formed on the base end side of the bolt portion are superposed on each other. Axis for folding rotation The bolt portion is configured to include a shaft attachment portion, and the brace mounting portion is attached to the reinforcing brace by projecting the shaft attachment portion from the front end side thereof and screwed into the hook. Is fixedly attached to the suspension bolt together with the hanging metal fitting by its tightening operation, and the reinforcement brace is configured to be adjustable with respect to the inclination angle via the shaft attachment portion. The part is allowed to rotate at any construction allowable angle of the reinforcing brace, but it can also be used as an abutment means that abuts against any part of other members in order to restrict further unnecessary rotation. It is characterized by being.

The present invention is configured as described above, so that the reinforcing brace and the hanging bracket are connected to each other via the connecting bracket so that the angle can be adjusted. In some cases, when hanging the hanging bracket on the top of the suspension bolt, the hanging bracket is restricted from rotating more than necessary, the latching posture is maintained, it is difficult to hook, and the state where it cannot be hooked can be surely avoided, the angle It is possible to perform the same latching work as that using a non-adjustable connecting bracket and maintain work efficiency as it is, and after construction, when the ceiling is shaken due to an earthquake etc. Even if a load in the direction of (stretch / pull) is applied, it is possible to regulate the reinforcement brace from changing beyond its construction allowable angle. On the other hand, a bolt portion fixed and attached together with a hanging bracket at a predetermined inclination angle, for example, an inclination angle of about 45 °, receives a load in the push-pull direction and transmits the load, and a large load is applied in the torsion direction. And the seismic balance of the entire reinforcing structure can be maintained well.

Hereinafter, the embodiment of the present invention will be described in detail based on a connection structure of ceiling reinforcing braces exemplified as a preferred embodiment.
In the drawings, reference numeral 1 denotes a ceiling casing, and a plurality of suspension bolts 2 are suspended on the ceiling casing 1 at a predetermined interval, and a ceiling panel is laid on the lower end of the suspension bolt 2. The unit ceiling surface is formed by assembling the T bar 4 in a lattice shape on the entire ceiling surface via the T hanger 41.

Reference numeral 5 denotes a reinforcing brace attached between the suspension bolts 2 with one end laid on the ceiling housing 1 side and the base end on the T-bar 4 side serving as the ceiling surface. A hanging metal fitting 6 is attached to the upper part of the suspension bolt 2 via 7.
The reinforcing brace 5 is formed of a channel material, and the base end side of the reinforcing brace 5 is fixed by screws with a mounting bracket 41 a attached to the lower part of the suspension bolt 2. .

The hook 6 is formed by bending a plate-like body and integrally forming a nut 61, bifurcated upper and lower locking pieces 62, 63, and a support piece 64 for supporting a distal end edge of a bolt 72 of a connecting fitting 7 described later. Has been.
The nut portion 61 is provided with a nut hole (not shown) into which the bolt portion 72 is screwed and disposed at a position where the tip of the bolt portion 72 can come into contact with the suspension bolt 2. The upper locking piece 62 has an angle of approximately 90 degrees (approximately 45 degrees with respect to the suspension bolt 2), and the lower locking piece 63 is approximately 130 degrees (approximately horizontal direction orthogonal to the suspension bolt 2). Are bent at different lengths and angles. As a result, when the bolt part 72 is screwed into the nut part 61, the reinforcing brace 5 is arranged on the substantial axis of the suspension bolt 2, and an inclination of approximately 45 degrees is obtained.

The upper locking piece 62 and the lower locking piece 63 are each formed with a substantially C-shaped locking portion for locking the suspension bolt 2 in a hook shape. Is formed so that the basic inclination angle (approximately 45 degrees) of the reinforcing brace 5 can be enjoyed, and each of them forms a support piece and the reinforcing brace 5 is linear with respect to the hanging bolt 2. It is to be locked to.
The support piece 64 is a guide piece that accurately abuts and guides the tip of the bolt portion 72 to the suspension bolt 2, and when the tip of the bolt portion 72 abuts the suspension bolt 2, On the other hand, the nut portion 61 has a function of supporting the bending stress so as not to be applied, and is bent using the lower side of the C-shaped formation of the locking portion. This hanging metal fitting 6 is a well-known thing disclosed by patent document 2, and omits detailed description.

  The connecting bracket 7 has a predetermined inclination angle between a brace mounting portion 71 attached to the front end side of the reinforcing brace 5 and a nut portion 61 provided facing the substantially axis of the suspension bolt 2 of the hanging bracket 6. A bolt portion 72 screwed with an inclination angle of about 45 °, and a plate-like tip portion 71a of the brace mounting portion 71 and a plate-like base portion 72a formed on the base end side of the bolt portion 72, It is configured to include a shaft mounting portion 73 that is superposed and is pivotally mounted by a rivet so as to be bent and rotated.

Next, an embodiment in which the connection fitting 7 is specifically configured will be described with reference to FIGS. The brace attaching portion 71 of the connecting fitting 7 in the present embodiment is entirely formed of a plate-like member, and has bent pieces 71c on both sides so as to cover the channel-shaped reinforcing brace 5 from the front end side. A mounting portion 71b formed in a U-shape, and a truncated triangular plate-shaped tip having inclined bent pieces 71d on both sides formed by extending a bent piece 71c from the attached portion 71b. Part 71a.
The bolt portion 72 includes a screw portion 721 that is screwed into the hanging metal fitting 6 and a plate-like base portion 72a that extends from the base end side through a tapered surface.

  Then, the plate-like tip portion 71a and the plate-like base portion 72a are overlapped with each other and are pivotally attached by rivets (axially-attached portions 73). Both sides of the plate-like base portion 72a including the portion extending below the shaft-attaching portion 73 of the plate-like base portion 72a that is an arbitrary portion of the bolt portion 72 are arbitrary portions in the brace mounting portion 71 as other members, that is, The inclined bent piece 71d is brought into contact with an angle of about ± 15 ° determined as an arbitrary construction allowable angle of the reinforcing brace 5. In addition, this construction allowable angle value may be revised. As a result, the plate-like base 72a of the bolt part 72 also serves as a contact means, and the inclined bent piece 71d functions as a contact piece of the plate-like base 72a. After the part 72 is attached, the angle of the reinforcing brace 5 is restricted.

4 and 5 show another embodiment in which the connecting fitting 7 is specifically configured. The brace mounting portion 71 of the connecting fitting 7 in this embodiment is entirely formed by a flat plate-like member. The shaft-attached portion 73 and the bolt portion 72 are protruded from the front end side of the channel-shaped reinforcing brace 5 and attached thereto, and the protruding portion is used as a plate-like tip portion 71a to the reinforcing brace 5. The part to be the mounting surface is configured as a mounting part 71b. In addition, the structure which makes the axial attachment part 73 and the bolt part 72 project from the front end side of the reinforcement brace 5 should just project from the cut surface of the reinforcement brace 5, for example, the reinforcement brace 5 This includes a mode in which a U-shaped notch is provided at the center portion of the cutting surface on the front end side, and the shaft attachment portion 73 is disposed in the U-shaped notch so as not to protrude from the front end surface.
The bolt portion 72 has a screw-like portion 72b screwed into the hanging bracket 6 and a plate-like base portion 72a formed to extend through a stepped portion 72c that is dropped from the taper surface on the base end side. The bottom of the plate-like base 72a is formed in a straight line.

Similarly, the plate-like tip portion 71a and the plate-like base portion 72a are overlapped with each other and are pivotally attached by a rivet (axially-attached portion 73). As described above, the stepped portion 72c of the plate-like base portion 72a which is an arbitrary portion of the bolt portion 72 is an arbitrary portion in the brace mounting portion 71 as another member, that is, the brace mounting portion 71 (plate-shaped tip portion) facing the stepped portion 72c. The corners of the front end surface 71a) come into contact with each other at an angle of ± 15 ° determined as an arbitrary construction allowable angle of the reinforcing brace 5.
Further, the mounting portion 71b of the brace mounting portion 71 is attached to the bottom portion of the plate-like base portion 72a with a predetermined gap so as to be opposed to the front end side cut surface with respect to the reinforcing brace 5, and arbitrary portions of other members As a cut surface of the reinforcing brace 5 so as to come into contact with the corner of the bottom at an angle of ± 15 °.
Thereby, the plate-like base portion 72a of the bolt portion 72 also functions as a contact means, and the stepped portion 72c and the bottom portion thereof are respectively the tip surface of the plate-like tip portion 71a and the cutting surface on the tip side of the reinforcing brace 5. The two portions are in contact with each other, and the angle of the bolt portion 72 is regulated. The plate-like base portion 72a is formed to be elongated by extending between the shaft mounting portion 73 and the screw portion 72b, and only the bottom portion of the plate-like base portion 72a is brought into contact with the cutting surface on the front end side of the reinforcing brace 5. May be.

In the form of the embodiment of the present invention configured as described above, a unit ceiling surface is formed by assembling a T-bar 4 or the like for laying a building panel via a plurality of suspension bolts 2 suspended on the ceiling frame. When the reinforcing brace 5 is attached with the tip end side between the suspension bolts 2 and 2 inclined to the ceiling housing side and the base end side inclined to the ceiling surface side, the connecting bracket 7 is attached to the tip end side of the reinforcement brace 5. The hanging metal fitting 6 attached so as to be able to be bent and rotated through is suspended on the upper side of the suspension bolt 2.
The connecting bracket 7 has a predetermined inclination angle (approximately 45 °) between a brace mounting portion 71 attached to the reinforcing brace 5 and a nut portion 61 provided facing the substantially axial line of the suspension bolt 2 of the hanging bracket 6. ), And a plate-like tip portion 71a formed on the front end side of the brace mounting portion 71 and a plate-like base portion 72a formed on the base end side of the bolt portion 72. It is provided with a shaft mounting portion 73 that is superposed and bent so that it can be bent, and the brace mounting portion 71 is attached to the reinforcing brace 5 by projecting the shaft mounting portion 73 from the tip side. The bolt portion 72 screwed into the hanging bracket 6 is fixedly attached to the suspension bolt 2 together with the hanging bracket 6 by the tightening operation thereof, and the reinforcing brace 5 is inclined at a predetermined inclination via the shaft mounting portion 73. Configure the angle to be adjustable based on the angle (approximately 45 °) On the other hand, any part of the bolt part 72 is allowed to rotate at any arbitrary construction allowable angle (angle adjustment) of the reinforcing brace 5 but is in contact with any part of another member so as to restrict any unnecessary rotation. It is configured to be capable of restricting the angle by also being used as a contact means.

With this configuration, the reinforcing brace 5 and the hanging bracket 6 are connected via the connecting bracket 7 so that the angle can be adjusted, and the reinforcing brace 5 is installed between the suspension bolts 2 and 2 in an inclined manner. In some cases, when the hanging bracket 6 is hooked on the upper part of the suspension bolt 2, the hanging bracket 6 rotates more than necessary, and the upper locking piece 62 and the lower locking piece 63 of the hanging bracket 6 face downward. And the latching posture is maintained, it is difficult to hook and the state where it cannot be hooked can be surely avoided, and the posture where the upper locking piece 62 and the lower locking piece 63 always face the suspension bolt 2 is ensured. Thus, the same latching operation as that using a connection fitting whose angle cannot be adjusted can be performed, and the work efficiency can be maintained as it is.
Moreover, after the bifurcated upper locking piece 62 and the lower locking piece 63 are hooked and locked on the upper side of the suspension bolt 2, the bolt portion 72 is tightened by the rotation operation from the base end side of the reinforcing brace 5. In the case where the conventional angle adjustment is not possible, the state in which both of the bifurcated locking pieces 62 and 63 cannot be latched at the same time due to the inclination angle of the reinforcing brace 5 is eliminated. Can be firmly attached to the suspension bolt 2 together with the hanging bracket 6, and there is an advantage that an optimum truss moment can be obtained for a festival in which the reinforcing brace 5 is inclined and attached.

Furthermore, after construction, when the ceiling is shaken due to an earthquake or the like, even if a load in the direction of pushing (pushing / pulling) is applied to the pivoting portion 73, the reinforcing brace 5 has its allowable construction angle (strut). And a bolt portion 72 fixedly attached on the axis at an inclination angle of about 45 ° with the hanging bracket 6 with respect to the suspension bolt 2. The load in the push-pull direction is received and the load is transmitted, so that a large load such as a twist direction is not applied, and the seismic balance of the entire reinforcing structure can be maintained well.
That is, as shown in FIG. 1, when the reinforcing brace 5 is linearly attached to the bolt part 72 at an inclination angle of about 45 °, the bolt part 72 is Since the suspension bolt 6 is firmly attached to the suspension bolt 2 with its tip abutted, and the base end side of the reinforcing brace 5 is firmly attached to the attachment bracket 41a, the inclined state is maintained. Although it can be maintained, when a large vibration load is applied (when the entire ceiling surface is greatly shaken), the inclination angle of the reinforcing brace 5 is displaced in the vertical direction with the pivot portion 73 as a fulcrum. However, since the arbitrary part (both sides of the plate-like base part 72a) of the bolt part 72 is in contact with the arbitrary part (inclined bent piece 71d) of the other member (brace mounting part 71), the reinforcement brace 5 is allowed to be installed. It is regulated that the angle is changed beyond the angle, and the reinforcing function as a brace can be maintained.

  Further, as shown in FIG. 6, when the reinforcing brace 5 is attached at an inclination angle of about 60 ° (or 30 °), even if a normal load is applied to the shaft attachment portion 73, the inclination state is the same as described above. However, when a large shake is applied, the inclination angle of the reinforcing brace 5 tends to be displaced with the pivoting portion 73 as a fulcrum. However, the downward displacement of the reinforcing brace 5 is that any part of the bolt part 72 (the side part on the lower side (or upper side) of the plate-like base part 72a) is immediately selected by any other member (the brace mounting part 71). Since it is brought into contact with the portion (lower (or upper) inclined bent piece 71d) and further angle variation is restricted, it is possible to suppress a large shake by the action of damping the inertia force in the opposite direction. The As a result, it is restricted that the angle exceeds the construction allowable angle, and the reinforcing function as a brace can be maintained. In addition, if attachment of such a reinforcement brace 5 is constructed in the cross state as the whole ceiling, one shaking can also be suppressed by the other reinforcement brace 5.

  Further, by setting the arbitrary part of the bolt part 72 as the plate-like base part 72a, the length, size, shape, etc. of the plate-like base part 72a itself can be freely changed, and desired parts such as the bottom and side parts thereof can be changed. For example, with the brace mounting portion 71, the reinforcing brace 5 and the like as other members, contact means for abutting against a desired arbitrary part such as each surface portion of these other members can be easily constructed, Variations in the configuration that restricts the angle can be achieved. In addition, although the arbitrary part of the bolt part 72 is the plate-like base part 72a, the screw part 72b may be used, and the plate-like base part 72a is in direct contact with an arbitrary part such as the brace attaching part 71 or the reinforcing brace 5. However, the present invention is not limited to this, and a contact piece (stopper piece) or the like may be separately attached, and may be in contact with an arbitrary portion of the hanging bracket 6. Anyway.

As an arbitrary part of the other member with which the plate-like base portion 72a comes into contact, a contact piece is bent to face the plate-like tip portion 71a of the brace mounting portion 71, and both side portions of the plate-like base portion 72a are formed on this, respectively. It is configured to abut. In other words, the brace mounting portion 71 is attached to the channel-shaped reinforcing brace 5 from the front end side thereof so as to have a U-shaped attachment portion 71b having bent pieces on both sides, and the attachment portion 71b. The bent piece 71c is formed so as to be inclined and extended, and is formed of a plate-like tip 71a having inclined bent pieces 71d on both sides, and the bent piece 71d of the plate-like tip 71a is connected to another member. As an arbitrary part, it can comprise so that the both sides of the plate-shaped base 72a may contact | abut.
When configured in such a contact relationship, both side portions of the plate-like base portion 72a and the inclined bent piece 71d can be contacted by planar contact, and the load received by angle regulation is dispersed to improve contact strength. be able to. Moreover, since the contact surface area can be changed simply by extending the plate-like base portion 72a below the shaft mounting portion 73, it is easy to manufacture the contact strength.

Further, the bottom of the plate-like base 72a is formed in a straight line, and the bottom is attached to the reinforcing brace 5 with a predetermined gap so as to face the cut surface thereof, and the attaching portion 71b of the brace attaching portion 71 is attached. And the arbitrary site | parts of another member can be comprised as a cut surface of the reinforcement brace 5 contact | abutted with the corner | angular part of the said bottom part.
With this configuration, when the reinforcing brace 5 can be attached at 45 °, the angle of the brace attaching portion 71b is adjusted with the bottom of the plate-like base 72a abutting (adhering) to the cut surface of the reinforcing brace 5 It can be attached impossible, and by adjusting the gap between them, the angle restricting position within the range of allowable construction angle can be arbitrarily set, and the deflection angle of the reinforcing brace 5 can be ± 15. An arbitrary angle can be set within the range of °.

Further, a stepped portion 72c that falls off from the screw portion 72b via a tapered surface is formed on the plate-like base portion 72a of the bolt portion 72, and a brace that contacts an arbitrary portion of the other member facing the stepped portion 72c. It can be configured as a tip corner of the mounting portion 71.
If comprised in this way, in addition to contact | abutting with the front-end | tip surface of the level | step-difference part 72c and the plate-shaped front part 71a, the contact | abutting with the bottom part of the plate-shaped base part 72a mentioned above and the front end side cutting surface of the reinforcement brace 5 is used together. Thus, the angle can be regulated by contacting the two locations.

Further, the plate-like base portion 72a of the bolt portion 72 is arranged on the U-shaped inner surface side of the reinforcing brace 5 and attached to the reinforcing brace 5 and the attaching portion 71b is attached (attaching the attachment state shown in FIG. 5 upside down) Further, the plate-like base portion 72a is extended below the shaft-attached portion 73, and both sides (corner portions and side surfaces) of the bottom portion of the plate-like base portion 72a are raised on the U-shaped sides of the reinforcing brace 5. Arbitrary portions of the other members can be configured as both-side rising pieces of the reinforcing brace 5 so as to contact each of the pieces. With this configuration, it is possible to change the shape of the plate-like base portion 72a so that the shape of the plate-like base portion 72a is wide, or the side surface on the bottom side is abutted on both sides of the reinforcing brace 5 with a predetermined area.
The connecting metal fitting 7 is not limited to the reinforcing brace 5 of the channel material, but can be applied to a bolt material. At that time, a nut for screwing the front end side of the bolt material into the attaching portion 71b of the brace mounting portion 7 A section should be provided.
